[0002] The limit mechanism for bushing press-fitting is used to limit the bushing press-fitting process. The digital press-fitting machine is a new type of mechatronic precision machine tool, which is widely used in the press-fitting, assembly, stamping, molding and pressure assembly of various parts and components.

[0003] The reference authorization number is "CN 217728542 U", and the name is "A limiting mechanism for bushing press-fitting". Although this application solves the problem that "at the current stage, the bushing is directly pressed into place by a single plate during the pressing process, and this process cannot limit the inside of the bushing during the pressing process, and cannot be adjusted according to the height of the bushing press-fitting, the flexibility is insufficient, and the limiting mechanism during the pressing process is not stable enough", it also has some defects. For example, the above application cannot limit the press-fitting of bushings of different specifications and models, and can only limit the press-fitting of bushings of a fixed specification. In actual use, most of the time, bushings of different specifications and models need to be pressed and assembled. The above application has great limitations in use, so a limiting structure for a bushing press-fitting machine for an operating arm is proposed to solve the above-mentioned technical problems.
