Clamp device for machining center

Abstract

A clamp device for a machining center comprises a positioning unit, a clamp body and a clamping unit. According to the positioning unit, a machining reference face A and two positioning pin holes of a part to be machined are positioned through one-face two-hole. A clamp body face B is arranged on the clamp body. The part to be machined is fixed into the clamp body, and the machining reference face A corresponds to the clamp body face B. The clamping unit is connected with the clamp body, and the clamping unit and the clamp body are matched to extrude the part to be machined fixed into the clamp body in the direction of the clamp body face B. The clamp device has the beneficial effects that through the clamping unit, the part to be machined can be fixed according to the requirement, and the efficient drilling work is achieved; through combination of the clamp body and a drilling module, the device space can be saved, positioning is accurate, and the machining precision can be guaranteed; and through an auxiliary bearing unit, the part to be machined can be supported and protected in the clamping process; and through a rotating unit, the machining operation requirement in the side-mounting state is met.

Description

technical field [0001] The invention relates to the technical field of machining of mechanical parts, in particular to a special fixture for a machining center for drilling back cover holes. Background technique [0002] In recent years, with the rapid development of modern science and technology, CNC machine tools have been widely used in production. CNC machine tools are short for digital control machine tools, and they are automatic machine tools equipped with program control systems. The control system can logically process programs with control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the numerical control device through the information carrier. After calculation and processing, various control signals are sent by the numerical control device to control the movement of the machine tool, and the parts are automatically processed according to the shape and size required by the drawing. CNC machine tools solve c...

[0004] Therefore, the back cover, as one of the main basic parts of the reducer, has a complex shape and high precision requirements. When drilling the 8-φ10.5 bottom surface and the 6-M12 threaded bottom hole on the A surface, tighter processing conditions are required. For the machining center Whether the requirements of processing accuracy can be achieved will directly affect the performance of the reducer; if a general-purpose fixture (such as a machine vise) is used, it is difficult to achieve positioning and clamping, and the processing accuracy cannot be guaranteed, which will affect the processing efficiency of the workpiece and thus affect the output.

If a combined fixture is used, the fixture has a large size and bulky size, takes up a lot of space on the machining center, is not easy to implement, and the fixture has poor rigidity, a large reserve of required components, and a high one-time investment cost, which affects processing. the cost of
