Detailed ways

The specific implementation of the present utility model will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

As shown in Figures 1 to 3, the positioning fixture for the milling machine includes a base plate 7, the base plate 7 is a flat plate structure, and the rear plate 2 and the cylinder integrated plate 8 arranged at intervals in parallel are arranged on the base plate 7. A side baffle plate 5 is arranged between the rear plate and the integrated plate of the cylinder body above, and a group of piston assemblies 9 that are retractable toward the rear plate are arranged on the integrated plate of the cylinder body.

A group of products to be processed is placed side by side on the bottom plate 7, and a group of products is placed between the rear plate and the integrated plate of the cylinder body. The piston assembly in the integrated plate of the cylinder body is clamped and positioned. One-time clamping can process multiple One-piece product, high work efficiency, easy clamping operation, reduces the work intensity of the operator, can ensure the processing accuracy, and easily ensure the product identity.

A group of base plate shim irons 3 are arranged on the base plate 7 between the rear plate and the integrated plate of the cylinder body. Preferably, the base pad iron 3 is arranged corresponding to the piston rod of each piston assembly. The height of the pad iron on the bottom plate is different to adjust the initial height of the product positioning.

A detachable tailgate 4 is provided on the inner side of the backboard 2 . The rear baffle plate 4 is located between the rear plate and the integrated plate of the cylinder body, and is arranged corresponding to the piston assembly, and the force is uniform and the positioning is reliable.

The side baffles 5 are a pair, which are respectively arranged at the two ends of the base plate, and a bar assembly 6 is arranged between the two side plates. A tie rod assembly 1 is arranged between the rear plate and the integrated plate of the cylinder block. The tooling can be disassembled and assembled, which is suitable for the processing of products of different sizes and specifications, and has strong versatility.

A cylinder cover plate 10 is provided on the outer side of the cylinder integrated plate 8 , and a hydraulic channel connected with the piston assembly is provided in the cylinder cover plate 10 . There can be several cylinder cover plates, which are convenient for processing. The cylinder cover plates are fixed on the cylinder body integration plate by fasteners, and the hydraulic passages in the adjacent cylinder cover plates are connected by joints 11.

A movable spacer 12 is provided on the bottom plate 7 corresponding to the piston rod of the piston assembly. The movable pads 12 are a group, and one is set corresponding to each piston assembly. The piston rod is not in direct contact with the product, the movable pad has a large force bearing area, the positioning is reliable, and the product surface is not easy to produce indentation.
