[0016] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0017] Combination Figure 1 , Figure 3 As shown, a device for symmetrically milling a workpiece includes a base 2, a core shaft 1, a sealing ring 6, and a closing nut 3.
[0018] Base 2 is mainly coordinated with the center of the milling machine table to determine the center of the milling machine, using transition coordination, combined with Figure 3 As shown, a U-shaped groove 7 is formed on the base 2 so as to fix it on the machine tool workbench; at the same time, the problem of insufficient tool travel of the milling machine is solved.
[0019] Combination Figure 2 As shown, the mandrel 1 is a stepped columnar structure, and the mandrel 1 cooperates with the base 2 to keep the axis of the mandrel 1 and the axis of the base 2 and the milling machine table in the same straight line.
[0020] The core shaft 1 cooperates with the workpiece 4. At this time, the hexagonal square hole of the workpiece has not been processed and formed, and is still not a circular inner hole. The core shaft 1 and the workpiece 4 cooperate through the inner hole of the workpiece 4, which makes it easy to find the symmetry surface, so that the workpiece 4 can be processed more conveniently and efficiently.
[0021] The closing nut 3 is mainly used to fix the workpiece 4 on the core shaft 1. Tightening the closing nut 3 presses the workpiece 4 against the base plate 5, making it easier to clamp and position the workpiece 4.
[0022] The process device is mainly used to solve the problem of batch processing of workpieces 4. It only needs to be clamped and no tool alignment is required, because the tooling has ensured that the center of the workpiece 4 coincides with the center of the machine tool. At the same time, the technical requirements for processing the workpiece 4 are guaranteed; moreover, the work efficiency is significantly improved.
[0023] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
