In order to solve the technical problems, the utility model provides a boring and milling clamp for large shaft parts, which is firmly clamped by adopting a surface contact scheme, improves the machining precision of products, and comprises a V-shaped clamp body, wherein the V-shaped clamp body is provided with a plurality of clamp characteristic bodies according to the size of the parts, the single clamp characteristic bodies are in an axisymmetric structure and are cast, the center of each clamp characteristic body is provided with a V-shaped groove surface characteristic, the clamp characteristic bodies are reinforced by rib plates in the vertical direction, and meanwhile, two sides of the clamp characteristic body in the horizontal direction are provided with grooves for fixing side plates, and the bottom plate of each clamp characteristic body is provided with a U-shaped notch and a lifting screw;
The side plate is assembled with the fixture characteristic body through the screw, a plurality of groups of compression blocks are arranged between the side plate and the side wall of the part after the part is placed into the V-shaped fixture body, the upper end face of the side plate and the upper end face of the compression block are on the same horizontal plane, the combined drawing shows, a pressing plate is further arranged in the height direction of the compression block, the auxiliary assembly is clamped, in addition, the side face of the pressing plate is arranged on the side plate, and the side face of the pressing plate is tightly pressed and connected with the side plate through the screw II and the gasket.
In one embodiment of the utility model, the overall V-shaped clamp body adjusts the gap and number of clamp features based on the length of the shaft.
In one embodiment of the utility model, the U-shaped notch is assembled and connected with a workbench of the machine tool through bolts.
In one embodiment of the utility model, the bottom of the V-shaped groove surface feature is a plane, so that the shaft part after clamping is not interfered, the height of the clamp body is reduced, and the quality of the clamp body is reduced.
In one embodiment of the utility model, the contact surface of the compression block and the part is characterized by a curved surface and is consistent with the radian of the part, and the compression block can be replaced according to the diameter of the shaft.
Compared with the prior art, the boring and milling clamp has the advantages that the whole structure is simple, assembly and disassembly are very convenient, meanwhile, shaft parts with different diameters in a certain range can be adaptively adjusted, the compressing mode cannot cause out-of-round deformation of the round pipe parts, the compressing blocks are in surface contact with the shaft parts, and the stability and the part machining precision in the boring and milling process can be effectively improved.
