Background

In the automobile manufacturing line, the stations of the template workers need to be handed with the clamps every day. To address field size issues and rear complaints of body assembly, it is a routine matter to adjust the clamp. After a long period of use, the clamp has various aging problems, such as: screw tooth decay, pin fracture, tooling part deformation and the like. These all cause the tool parts of the clamp to be difficult to disassemble, thereby bringing much trouble to the adjustment of the clamp. When this happens, the operator at the station can only use chisels, pliers, hammers, etc. to knock and loosen the clamp. These operations waste a lot of adjustment time and physical effort of personnel and sometimes damage the tooling parts.

Taking the adjustment of an aged stuck chuck as an example, the operator needs to perform the following operations to perform the adjustment:

first, the fastening screw of the clamp is loosened.

The clamp needs to be loosened through the hammer due to aging and adhesion, and the hammer does not strike the force point on the clamp. To loosen the clamp, a chisel is inserted into the pad area and a hammer is used to strike the chisel to loosen the chuck.

After the chuck is slightly loosened, a chisel is inserted into the gap between the clamps, and the tool clamp is pried to increase the clamp gap.

The tool is then used to remove or add the required shims.

Finally, the tool clamp is assembled back, and the screw is fastened.

In the above steps, the process of inserting the chisel into the gasket area and knocking by using the hammer is time-consuming and labor-consuming, and the tool parts are easily damaged or the hands of operators are injured by smashing, so that great inconvenience is brought to the clamp adjusting work.
