Welding workstation fixture quick-changing mechanism
Technical field
This utility model belongs to Car main body element and manufactures field, it is adaptable to fixed, the quick-replaceable of mobile robot's welding workstation fixture and positioner.
Background technology
Along with stepping up of country's automated manufacturing level, car welding part manufacturing uses robot welding workstation, replace traditional manually-operated application to get more and more.Using robot welding workstation, equipment repeatable accuracy is high, good product consistency, Improving The Quality of Products, and work efficiency is high, personnel is freed from hard work.The layout of welding workstation fixture generally has two ways: one is that robot is fixed, and fixture is placed in robot periphery, the most fixed welding workstation, and robot periphery typically can put 3~4 set weld jigs;Another kind is that robot the most back and forth walks, and weld jig is put in track both sides, referred to as walking welding workstation, and 10~20 set weld jigs can be put in track both sides.In real work, owing to producing, product variety is various, number change big, needs often to change weld jig, can produce the demand of multiple product with a satisfied welding workstation.But the Comparision currently changing fixture is loaded down with trivial details, not only needs many people compounding practice, and the repetitive positioning accuracy adjustment after fixture is laid is also required to take the plenty of time.
Summary of the invention
This utility model provides a kind of welding workstation fixture quick-changing mechanism, big to solve existing welding workstation replacing fixture workload, the problem of holding time length.
nullThe technical solution of the utility model is: fixture mounting seat is between base and jack-up support,Base is by base plate、Lower location-plate one、Lower limiting board、Lower location-plate two、Bore convex、Lower location-plate three forms,Lower location-plate one、Lower limiting board、Lower location-plate two、Bore convex、Lower location-plate three notifies that bolt and base plate are fixing respectively and is connected,Fixture mounting seat is by upper location-plate one、Bore recessed、Upper limit plate one、Fixture installing plate、Upper location-plate two、Upper limit plate two、Upper location-plate three forms,Upper location-plate one、Bore recessed、Upper limit plate one、Upper location-plate two、Upper limit plate two、Upper location-plate three is connected by bolt and fixture installing plate are fixing respectively,Jack-up support is made up of supporting plate and limited block,Limited block is connected by bolt and supporting plate are fixing,Bore and convex recessed engage with cone,Lower location-plate two is fitted with the upper adjacent two sides of location-plate two,Lower location-plate one is fitted with upper location-plate one two sides,Lower location-plate three is fitted with upper location-plate three adjacent two sides.
The utility model has the advantage of: novel structure, fork truck is coordinated to use, the time changing, debugging weld jig on welding workstation can be shortened to about 5 minutes from original more than 1 hour, fixture repetitive positioning accuracy is high, shorten non-cutting time, improve work efficiency and utilization rate of equipment and installations, reduce manufacturing cost.

Detailed description of the invention
nullFixture mounting seat 2 is between base 1 and jack-up support 3,Base 1 is by base plate 101、Lower location-plate 1、Lower limiting board 103、Lower location-plate 2 104、Bore convex 105、Lower location-plate 3 106 forms,Lower location-plate 1、Lower limiting board 103、Lower location-plate 2 104、Bore convex 105、Lower location-plate 3 106 notifies that bolt is fixing with base plate 101 respectively and is connected,Fixture mounting seat 2 is by upper location-plate 1、Bore recessed 202、Upper limit plate 1、Fixture installing plate 204、Upper location-plate 2 205、Upper limit plate 2 206、Upper location-plate 3 207 forms,Upper location-plate 1、Bore recessed 202、Upper limit plate 1、Upper location-plate 2 205、Upper limit plate 2 206、Upper location-plate 3 207 is connected by bolt is fixing with fixture installing plate 204 respectively,Jack-up support 3 is made up of supporting plate 301 and limited block 302,Limited block 302 is connected by bolt is fixing with supporting plate 301,Bore convex 105 to engage with cone recessed 202,Lower location-plate 2 104 is fitted with the upper adjacent two sides of location-plate 2 205,Lower location-plate 1 is fitted with upper location-plate 1 two sides,Lower location-plate 3 106 is fitted with the upper adjacent two sides of location-plate 3 207.
The working method on quick-changing mechanism base being installed in welding workstation by the weld jig having been provided with fixture mounting seat is: adjusts fork truck fork spacing, is placed on fork by jack-up support;Operation fork truck, below jack-up mount to fixture mounting seat, rise fork, make jack-up support between upper limit plate one and upper limit plate two, what the hatching in Fig. 5 represented is jack-up support, and its arranged on left and right sides wants to leave space between upper limit plate one and upper limit plate two, continues to rise fork, the end face making jack-up support is fitted with fixture installing plate, forks fixture afterwards;Operation fork truck, fork truck fork is adjusted to suitable position and height, make the upper location-plate one in fixture mounting seat, upper location-plate two and upper location-plate San Tong method and the lower location-plate one on base, lower location-plate two, the laminating of lower location-plate three side, complete the fixture initial alignment shown in Fig. 6;Operation fork truck, slowly puts down fixture, makes the cone in four convex importing fixture mounting seats of cone on base recessed, gets final product automatic adjusting position and fit, completing the fixture shown in Fig. 7 and be accurately positioned;Being exited by fork truck fork, take off jack-up support, fixture installment work completes.
By the working method that the fixture installing quick-changing mechanism takes off from welding workstation it is: adjust fork truck fork spacing, jack-up support is placed on fork;Operation fork truck, is inserted into jack-up support below fixture mounting seat, makes jack-up support between upper limit plate one and upper limit plate two, fork fixture;Operation fork truck, exits fork truck fork, and fixture is transferred to storing place;Operation fork truck, slowly puts down fixture, is exited by fork truck fork, take off jack-up support, and fixture takes off work and completes.
