A robot welding precise positioning automatic clamping mechanism

Abstract

The invention provides a robot welding precise positioning automatic clamping mechanism. The mechanism comprises a working table, a fixed base, a mounting rotary table, a vertical positioning mechanism and a lateral positioning mechanism; the fixed base is fixedly arranged on the working table, and a vertical positioning hole is formed in the fixed base; the mounting rotary table is detachably arranged on the fixed base, and a lateral positioning hole is formed in the mounting rotary table; the vertical positioning mechanism is arranged on the mounting rotary table, and the vertical positioning mechanism corresponds to the vertical positioning hole and is arranged in the vertical positioning hole in a penetrating mode; the lateral positioning mechanism is arranged on the fixed base, corresponds to the lateral positioning hole and is arranged in the lateral positioning hole in a penetrating mode. The automatic clamping mechanism has the advantages that the die change precision is high,it takes less time to conduct die change, and operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of robot welding equipment, and relates to an automatic mold locking mechanism for precise positioning of robot welding. Background technique [0002] Robot welding equipment is a kind of efficient welding equipment, which includes a turntable and a tooling mold that needs to be installed on the turntable. The tooling mold is a robot welding fixture. [0003] In the daily production process, tooling molds are used frequently, and the process of changing molds often takes a long time, thus delaying production; and at present, tooling molds are used as robot welding fixtures, so their weight is very large, generally 300KG As mentioned above, it is very troublesome to change the mold, and it takes 2-3 people to change the mold together, and when changing the mold, it is necessary to push the jig to align with the pin hole for manual insertion, and then lock 4 M16 screws to lock it, which requires many people. ...

[0003] In the daily production process, tooling molds are used frequently, and the process of changing molds often takes a long time, thus delaying production; and at present, tooling molds are used as robot welding fixtures, so their weight is very large, generally 300KG As mentioned above, it is very troublesome to change the mold, and it takes 2-3 people to change the mold together, and when changing the mold, it is necessary to push the jig to align with the pin hole for manual insertion, and then lock 4 M16 screws to lock it, which requires many people. It takes a long time and it is difficult to change the mold

[0004] In addition to the difficulty of replacing tooling molds, the installation accuracy is also relatively low. Once replaced, the accuracy of mold replacement is also relatively low, which will lead to deviations in the welding path of the robot and seriously affect the welding effect.
