[0002] The patent application number retrieved is: "CN202022826973.4". A fixing device for the production of gear bearing plugs includes a moving mechanism, a processing mechanism, and a fixing mechanism. The processing mechanism is installed above the moving mechanism, and the fixing mechanism is installed on the side of the moving mechanism. The utility model sets up a processing mechanism, uses an upper pressure plate and a lower pressure plate to clamp the cutter head, and uses fixing bolts to fix the upper pressure plate and the lower pressure plate. When the cutter head is severely worn and needs to be replaced, it is only necessary to remove the fixing bolts to replace the cutter head, which saves time and effort. By setting up a fixing mechanism, the workpiece is placed between multiple holders, and the electric chuck controls the holder to approach the workpiece. Multiple holders contact the workpiece to fix it on the electric chuck. The fixing process is simple and convenient, and the clamping effect is good.
