Locking device for welding rotary jig of automobile body

Abstract

The invention discloses a locking device for an automobile body rotary welding clamp, which is mounted at the bottom of the clamp, and comprises a pedal arm, a locking mechanism, and a reset mechanism, wherein one end of the pedal arm is hinged with a BASE plate of the clamp; the other end of the pedal arm is used for stepping on; the locking mechanism is connected with the BASE plate of the clamp, and comprises a locking rod; the locking rod can move up and down; the upper end of the locking rod is inserted into a lock hole formed in a clamp swing table; the lower end of the locking rod is connected with the pedal arm; the pedal arm drives the locking rod to move; the reset mechanism is connected between the BASE plate of the clamp and the pedal arm, and used for resetting the pedal. Compared with the prior art, the locking device has the advantages that an operator can step on the pedal arm, so that the pedal arm drives the locking mechanism to conduct corresponding actions and further unlock and lock the clamp. Therefore, the locking device is convenient to operate; the operator is not required to stoop during operation, which reduces labor intensity and working hours, and eliminates safety hazards in the operation process.

Description

technical field [0001] The invention relates to an automobile tooling, in particular to a locking device for an automobile body welding rotary jig. Background technique [0002] At present, the tooling used for positioning workpieces in various welding workshops of automobile factories is mainly fixtures. Through the fixture, the workpiece can be quickly and accurately positioned and supported and maintained properly, so that all the workpieces produced can be fixed within a specific range, ensuring the precision and interchangeability of the products. Usually, fixtures are designed as static mechanisms, but in order to ensure the safety and convenience of operation, some fixtures need to be designed as dynamic mechanisms, such as plane rotation. The rotation system arranged in the fixture bottom plate and the fixture support can make the fixture body rotate 360 ​​degrees on the plane (rolling bearings are also equipped to make the rotation flexible and light). Such a syst...

Problems solved by technology

[0003] At present, the locking mechanism of the rotary fixture in the welding workshop is mainly based on the latch structure. Because of the low layout of this locking structure, the personnel need to bend over during the process of pulling out and inserting the pins, which is labor-intensive and affects the working hours. At the same time, the head of the personnel is easy to collide with the fixture during the process of standing up, causing the employee to be injured. In addition, most of these pins are arranged outside the base plate of the fixture (fixture base plate), and the personnel will not pay attention when walking between the stations. Being tripped is also a major safety hazard in the welding workshop
