Description

Technical Field

[0001] This utility model relates to the field of bushing processing technology, and in particular to a cutting seat for symmetrical workpiece division. Background Technology

[0002] During the machining process of bearing bushings, since the surface of the oil filling groove needs to be machined on the inner wall, smaller bushings can be directly machined by a lathe. However, some larger workpieces are too long and exceed the machining range of the lathe. Therefore, it is necessary to symmetrically split the workpiece longitudinally and then use a milling machine to mill the groove.

[0003] When cutting existing cylindrical bushing workpieces, they only need to be placed on two parallel, straight support bases, and the curvature of the cylindrical surface will allow for natural positioning. The cutting saw can then be placed in the middle of the two support bases to symmetrically divide the workpiece. Due to the high weight of large workpieces, they are relatively stable after placement. After setting up a surrounding enclosure, corresponding fixing fixtures are generally not required, which can save time in fixing the workpiece and improve processing efficiency. However, some workpieces have special requirements, with one end being square rather than cylindrical. The cylindrical end can be self-positioned, but the square end cannot. The existing method is to use fixing fixtures for clamping and positioning. However, fixing fixtures are not only costly to install, but also increase processing time during processing, reducing overall processing efficiency. There is room for further improvement.
