Description

Technical Field

[0001] This utility model relates to the technical field of shaft processing equipment, and more specifically, to a shaft processing positioning structure. Background Technology

[0002] In shaft machining, drilling is a common process used to achieve pin positioning, lubrication channels, or assembly connections. To ensure the accuracy and efficiency of shaft drilling, specialized positioning structures and fixtures are typically required for precise positioning and clamping.

[0003] For example, patent CN221019903U discloses a shaft-type external cylindrical positioning drilling mechanism, including a base plate and a positioning assembly, with at least one positioning assembly slidably mounted on the base plate. The positioning assembly includes a positioning block and a side template, with a V-groove on the upper part of the positioning block, in which a machining shaft is placed. This shaft-type external cylindrical positioning drilling mechanism improves machining efficiency and reduces costs.

[0004] However, in actual use, the size of the V-groove is relatively fixed and cannot accommodate shafts of different specifications. When processing shafts of different specifications, the V-groove or other fixtures need to be replaced. Traditional fixture designs lack a quick replacement mechanism, resulting in a long replacement process and reduced production efficiency. At the same time, if the size of the fixture is fixed and cannot be replaced, it is difficult to be compatible with shafts of different sizes, which limits the flexibility and versatility of the production line. Therefore, improvements are needed. Utility Model Content

[0026] In the embodiment, the shaft body machining positioning mechanism is fixed on the machine tool through the mounting table 100. When the shaft body is punched, the two ends of the shaft body are placed in the V-shaped groove 104, and one end of the shaft body on the fixed frame 101 is partially extended from the V-shaped groove 104 on the fixed frame 101, so that the end face of the shaft body is punched. The machine tool is provided with a punching mechanism on the side close to the extended shaft body to punch the shaft body.

[0027] In the embodiment, the plug 106 is fixedly connected with the limiting block 103, and the plug 106 is slidably connected with the insertion hole 105. When the limiting block 103 is installed, the plug 106 is inserted into the insertion hole 105 to complete the pre-installation of the limiting block 103 on the fixed frame 101 and the sliding frame 102. Then, the plug 106 is limited by the limiting assembly, so that the limiting block 103 is limited to avoid disengagement of the limiting block 103 from the fixed frame 101 and the sliding frame 102.
