Abstract

The invention provides a milling machine clamp. The milling machine clamp comprises a clamp body, a positioning device, a clamping device and a guide device, and the surface of the milling machine clamp is provided with a wear-resistant coating layer; the clamp body is provided with a baffle plate, and a pressing block is arranged on the baffle plate; and the positioning device comprises a positioning shaft, an end surface and a positioning pin, the positioning shaft is fixed on the baffle plate, and the positioning pin is arranged on the clamp body and is used for positioning a workpiece. According to the milling machine clamp, the workpiece can be reasonably positioned through cooperation among the clamp body, the positioning device, the clamping device and the guide device, the assisting time is shortened, then the milling efficiency is high, the labor production efficiency is improved, the worker labor intensity and the production cost are reduced, the end surface is used for limiting five degrees of freedom, moreover, the rotation degree of freedom is limited by combining the positioning pin, the workpiece can be completely positioned, so that the workpiece is easy to machineand control, and the size requirement of a product is ensured; and the quality of workpiece machining is stabilized and improved.

Description

technical field [0001] The invention relates to the technical field of metal processing, in particular to a milling machine fixture. Background technique [0002] A milling machine is a machine tool that uses a milling cutter to mill a workpiece, and is widely used in the field of machining. Usually the rotation of the milling cutter is the main movement, and the movement of the workpiece is the feed movement. It can process planes, grooves, various curved surfaces, gears, etc. In addition to machining planes, grooves, gear teeth, and threads of workpieces, milling machines can also process more complex profiles, and are widely used in machinery manufacturing and repair departments. The fixture on the milling machine is used to fix the workpiece. The current fixture is generally fixed directly on the worktable of the milling machine. The worktable moves left and right to process the workpiece or takes it down and replaces it with other surfaces for processing. For workpie...
