Abstract

The invention discloses a three-claw clamp which comprises a chuck and three clamping claws, wherein the three clamping claws are uniformly mounted on the chuck; one side of each of the three clamping claws is movably mounted on the chuck through a hinge piece; the other sides of the three clamping claws are mounted on a fixing disk through double-head studs; a cylinder is mounted on the fixing disk, and a cylinder rod is mounted in the cylinder and penetrates through the cylinder so as to be connected with the chuck through a hex nut; a protection cover is mounted on the outer side of the cylinder, and a threaded shank is mounted at the upper end of the cylinder; elastic antiskid pads are mounted on the clamping claws. The three-claw clamp provided by the invention is simple in structure and convenient to use; the clamping claws are mounted on the chuck and the fixing disk through the double-head studs and are convenient to remove and mount; the elastic antiskid pads are arranged on the clamping claws, so that micro deformation of a clamped piece in a clamping process can be prevented, and the product yield of the clamped piece is increased.

Description

Technical field

[0001] The invention relates to the technical field of clamp structures, in particular to a three-jaw clamp. Background technique

[0002] With the advancement of science and technology, in the production process, especially when the working environment is harsh and dangerous, it has become an inevitable trend to replace manual operations with manipulators. Manipulators replace manual operations, which not only guarantees personal safety, but also improves Work efficiency and avoid damage caused by manual operation errors.

[0003] The three-jaw fixture is the most common fixture for machining and clamping various parts. The fixture is easy to use and has a wide range of applications. It has long been standardized and manufactured. The prior art three-jaw clamp includes a chuck and three clamping jaws, and the three clamping jaws are evenly installed on the chuck. When in use, mechanical force is applied to the three clamping jaws, so that the reciprocating moveme...
