In the light of solder artificially baseplate horn board intensity of occurrence dimension deviation, labor is advanced malpractice, use servo to control a system to undertake emulation designing special fixture, can come true semi-automatic turn an operation, improved manufacturing efficiency and product quality effectively, reduced the labor intensity of handlers. Baseplate horn board soldering is a important production process, its purpose is will horny board solders through protruding welder fixed go up in housing, make electric machinery is able to install the wind hood in fan assembly. Baseplate horn board distributing have trisect all of cloth, also blame trisect distributings (pursue as follows) . Solder traditionally the method is: Handlers puts housing the basis baseplate solders in the fixture with custom-built height, will horny board is placed in the clamping apparatus that contains magnet steel housing is stuck inside fixed position piece; Of the welder of fixture park protruding that will contain baseplate solder on electrode; Step on next foot switch, protruding welder solders; The hand moves rotating clamp to provide the next horny board solders the position, repeat measure 3, till solder is over all horn board; Get off clamping apparatus, good solder baseplate is taken out, finish baseplate of horny board solder operation. Because baseplate sketch map turns artificially clamping apparatus, handlers withstands when solder the active force measurement of clamping apparatus is different, can cause error of existence of fixed position of horny board axial. In the meantime, handlers of whole unit process of cargo bandling should repeat roll for many times, cause handlers labor intensity is higher. A variety of problems affected product quality and manufacturing efficiency, accordingly we designed a semi-automatic part board fixture will solve afore-mentioned problems. According to baseplate horny board solders the characteristic of working procedure, need can repeat rotational and fixed point of view by the requirement, we used reason servo electric machinery will command the rotational point of view when soldering. Servo electric machinery contains signal feedback, precision is tall, and can offer the roll that enough torsion drives clamping apparatus. In the meantime, use system of odd axis numerical control to control servo drive, use the process designing function of system of odd axis numerical control, our work out gives a program to come the movement when imitate solders artificially is ordinal, came true to solder automation. Solder to assure quality, we designed horny board to solder, with will put clamping apparatus, realize the function such as float of graduation roll, fluctuation, discharge. Thereby better land solved semi-automatic part board the interface of fixture and protruding welder, the biggest profit that turn the land used original device. Systematic hardware is designed 1, the composition of systematic composition system and run stream Cheng. 2, horny board solders a horny board solder action is to load rotational workpiece, provide platform of a float, pass by servo electric machinery solder gear deputy will command rotational point of view. Solder can drift up and down through bedspring, guide-post bushing and guide pillar, in the electrode inside the come away when roll, the electrode inside the impaction when soldering, when avoiding clamping apparatus to turn thereby brush touch, can rise effectively solder quality. With solder a form a complete set those who use is the clamping apparatus that improves on foundation of original and manual fixture, its action is fixed housing is mixed the relative position of horny board. Soldering on, we use the sucking disk that takes magnet steel to come grip fixture, replace artificial hand to press an action, fall off with making sure the clamping apparatus when soldering is not sent, avoid error of dimension of horny board axial. For the need of discharge, we still are soldering on installed discharge orgnaization, it passes connection of two air cylinder annulus of a discharge drives fixture to break away from the sucking disk that contains magnet steel, the discharge that finish. 3, servo servo electric machinery has torsion big, precision the tall, characteristic that can feedback, can control rotational angle and rotate speed according to pulse number. We chose Shanghai to open the 110HM-8M04030-F servo electric machinery of numerical control limited company, its bulk is compact, torsion achieves 4N.

M. Communicating servo drive system is the apparatus that controls servo electric machinery, we choose the word of KT270 total number that matchs with electric machinery photograph to communicate drive system. It uses DSP (digital signal processor) chip, accelerated data is collected and treat rate, make electric machinery moving performance good. In the meantime, it can set parameter on driver face plate directly, debug, monitoring system condition, the exterior is concise, the structure is compact. KT700B of system of odd axis numerical control is equivalent to the function of PLC in whole system. It has an input to output a function, take liquid crystal screen and clavier oneself, control of OK and direct online process designing and online monitoring. Undertake through it process designing imitate operates measure artificially, controallable semi-automatic horn board fixture. 4, electrical system and pneumatic system basically use control input and output dispatch name, with connection of protruding welder interface control actuator runs the place. Systematic software is designed 1, systematic parameter is installed (1) the setting setting that communicates servo driver shows condition is surveillant moving condition; The setting controls mode to control mode for the position, in order to dominate the niche of take-off of servo electric machinery; To make roll more smooth, the setting increases slowdown time appropriately; The setting protects limitation, for instance top rotate speed, highest torsion, bring about a system to be damaged with avoiding unusual situation to appear; Build craft file record to call the police parameter, know breakdown pattern of the system in time, adopt answer measure. (2) only axle control implement setting basis of the system try moving state, adjust each parameter, make its run stability; Set system parameter, definition process designing uses constant, reference point; Setting electron gear is compared, pass a setting to be able to turn clamping apparatus actually with pulse number establishs corresponding relationship, facilitating control; Set system extreme value, ensure the system is stable. 2, the program writes a program is to be based on only axle control implement offerred numerical control statement writes. The instruction uses order to arrange, according to handling the order when artificially, write a program. With SET the instruction accepts output signal, with WAT the instruction accepts input signal. SPEED instruction controls rate, POS instruction commands the position and point of view. In addition, still can use CALL to call a statement, execute similar order circularly. After the question that tries moving discovery and solution system had been established, have trial production. Moving process accords with design requirement, carry out according to the order that solders artificially, location is exact. In the meantime, the system can ask according to actual production, adjust traversal speed, satisfy the requirement that produces metre. But discover in real operation: Clamping apparatus and solder make and assemble quality reliable to systematic stability moving impact is very big. Accordingly, we undertook optimizing to clamping apparatus, undertake proper adjustment when assemble. At first, clamping apparatus is pressed easily to become warped first, cause error of measure of the product after soldering big. We increased to control apparatus beforehand on protruding welder, a squeezing ramming will solder first before soldering, increased jacket to solder in order to rise at the same time stiffness. However, discover after moving period of time, workpiece disengages clamping apparatus hard. Then, we are new nap clamping apparatus, adjust the position of the electrode on protruding welder, the workpiece when making solder gets power even, won't make workpiece deflection blocks dead clamping apparatus to bring about hard emergence. In the meantime, the pressure that adjusts discharge air cylinder and discharge annulus and solder clearance, when making air cylinder top goes out more smooth. Discharge air cylinder is when discharge, elastic force is very large, cause clamping apparatus easily to play when going out, make handlers gets hurt, damage at the same time clamping apparatus. We set dead block on workbench, clamping apparatus is being played after going out, contact dead block decelerate first, enhanced systematic security. Those who pass period of time try move, horny board fixture system can according to book a requirement, finish whole job job. The product quality that production gives accords with a design to ask, and averted the interference of factitious element, reduced the labor intensity of handlers. When fixture works, handlers can vacate those who move to have next work to assemble, improved manufacturing efficiency. Combine the application of servo, electromechanical unifinication technical application arrives in actual production, can bring more advantage to us, create bigger economic benefits.
