Vehicle clamp capable of fast replacing machined part

Abstract

The invention discloses a vehicle clamp capable of fast replacing a machined part. The vehicle clamp comprises a body arranged on a machine tool worktable, the front end of the body is provided with a pull rod connected with a machine tool oil cylinder, the front end of the body is sleeved with the machined part, an expansion sleeve is connected to the pull rod, wherein the expansion sleeve is used for being matched with the front end of the body to clamp or loosen the machined part when the machine tool oil cylinder drives the pull rod to move, and the expansion sleeve and the pull rod are of an integral structure. According to the vehicle clamp capable of fast replacing the machined part, the pull rod is arranged at the front end of the body, and the expansion sleeve matched with the front end of the body to clamp or loosen the machined part when the machine tool oil cylinder drives the pull rod to move is connected to the pull rod, so that the front end of the body is matched with the expansion sleeve to clamp or loosen the machined part. The expansion sleeve and the pull rod are of the integral structure, so that after machining, the pull rod can drive the expansion sleeve to axially move together and enable the expansion sleeve to be loosened, when the expansion sleeve is loosened, the part can be automatically loosed, in this way, cost can be reduced, and machining precision and machining efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of processing fixtures, and in particular relates to a turning fixture capable of quickly replacing processed parts. Background technique [0002] At present, the existing car fixtures are affected by the three characteristic parameters of the processed parts (the three characteristic parameters are the inner hole, the end face diameter and the axial dimension). When any parameter changes or exceeds a certain range of changes, the fixture needs to Re-design and manufacture, poor versatility. In this way, not only the cost of fixture input is increased, but also the time for switching processed products is greatly increased, which affects production efficiency. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned shortcomings of the prior art, and provide a turning fixture capable of quickly changing parts to be processed. The turning fixture not only ha...
