[0002] With the rapid development of mechanical equipment and high-end spare parts, five-sided machining centers have become indispensable processing equipment for workpiece manufacturing. Five-sided machining machines have high processing efficiency and high five-sided forming accuracy. For workpieces with spatial special-shaped surfaces, the conventional method is to use a five-sided machining center for processing. For the machining center fixture, it should be a one-time clamping condition to be able to process as many surfaces as possible. At present, the processing of special-shaped workpieces still requires multiple clamping to complete, and the size of the workpiece is strictly limited. The processing is not only time-consuming, but also very costly. If multiple processing stations are set up for simultaneous processing, multiple sets of clamping modules with clamping cylinders are required, which takes up a lot of space. Utility Model Content

[0005] Preferably, there are four support columns, all of which are located above the base of the box and arranged in a square at the four corners of the base of the box. The support plate is a square structure and has threaded hole groups at the four corners. The support plate is located above the support columns and the threaded hole groups of the support plate match the positions of the four support columns. A threaded hole is provided at the center of the support plate.

[0006] Preferably, the set screw is arranged at the center of the support plate, a hexagon socket bolt hole is arranged above the set screw, and the set screw can move up and down on the support plate through the external thread.

[0008] Preferably, the positioning mandrel is bolted to the center of the box base, the bottom layer is a circular structure and is bolted to the center of the box base, the middle layer structure matches the bottom shape of the special-shaped workpiece, and the top layer structure is provided with a threaded hole group.

[0009] The beneficial effects of the utility model are:

[0010] The utility model is used for clamping and positioning special-shaped workpieces, which solves the problem that traditional processing machines have few single processing surfaces for processing special-shaped workpieces and that processing of special-shaped workpieces requires multiple clampings to complete, reduces the number of clamping times and the number of manual measurements, and thus reduces the labor intensity of workers.

[0011] The box body tooling of the utility model is designed and manufactured with high precision, which can ensure the stability and precision of clamping, thereby improving the processing precision. At the same time, the box body tooling has a simple structure and is convenient to use and maintain.
