Description
Technical Field
The invention relates to the field of spot welding robot workstations, in particular to a quick change mechanism for a spot welding fixture.
Background
At present, when mechanical products such as automobiles are machined, a spot welding robot workstation is used for welding, in order to fix the products, the spot welding robot workstation is used for fixing the products by using a clamp, but in the machining process, different products need to be machined, the clamp needs to be switched, under the general condition, the spot welding robot workstation utilizes mechanical assistance such as a forklift to switch the clamp when the clamp is switched, the clamp collision and unstable positioning often occur, manual fixing needs to be carried out, and the position calibration of the robot needs to be carried out when the clamp is switched every time. Therefore, it is very important to solve the problems that the clamp needs to be manually fixed during switching and calibration is needed during each switching.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to provide a quick change mechanism for a spot welding fixture, which automatically completes fixture switching work by driving the fixture to move through a fixture moving universal wheel, ensures the accurate position of the switched fixture by matching a positioning sleeve and a positioning column for positioning, does not need to be calibrated again, improves the processing efficiency, and solves the problems that the fixture needs to be manually fixed during switching and needs to be calibrated during each switching.
The invention provides a quick change mechanism for a spot welding fixture, which comprises a base, wherein a support is arranged on the base, a positioning column is arranged on the support, a fixture table is arranged at the upper end of the base, fixture moving universal wheels are arranged at four corners of the fixture table, a positioning guide wheel and a positioning sleeve are arranged at the lower end of the fixture table, positioning is carried out through the matching of the positioning sleeve and the positioning column, a top-stretching air cylinder is arranged at the lower end of the positioning column, and the positioning column is driven to ascend through the top-stretching air cylinder and is contacted with the positioning sleeve.
The further improvement lies in that: the front side of the support is provided with a guide plate, and the moving direction is guided through the guide plate.
The further improvement lies in that: and a limiting sensor is arranged on the rear side of the positioning column, and the maximum moving position is limited and detected through the limiting sensor.
The further improvement lies in that: and a locking cylinder is arranged beside the positioning column and used for locking the positioning column.
Anchor clamps move the universal wheel through anchor clamps and move to fixing base parallel direction, and the location leading wheel continues to move to spacing sensor position along the deflector, and control system transmission signal gives control system, and control system transmission signal gives the top and stretches the cylinder, and the top is stretched the cylinder and is driven the reference column and leading-in to the position sleeve in, compresses tightly the cylinder and delays time and drive the compact heap and compress tightly to realize the location and the fixed of anchor clamps. Otherwise, the whole operation sequence is reversed, and the clamp can be smoothly replaced.
The invention has the beneficial effects that: remove the universal wheel through anchor clamps and drive anchor clamps and remove, accomplish anchor clamps switching work automatically to fix a position through position sleeve and reference column cooperation, guarantee that the anchor clamps position of switching is accurate, need not recalibration once more, improve machining efficiency, the design is simple, anchor clamps switching speed is fast, fix a position accurately and fixed stable, switch anchor clamps and do not need personnel to observe in the bottom, all by the control of sensing control system.
