Problems solved by technology

In the prior art, three screws and a heart-shaped chuck tooling are used for processing. This fixture structure has the following disadvantages: 1. Due to the vibration and rotation of the machine tool, the screws for clamping the shaft parts will loosen, and the work is unreliable; 2. Insufficient clamping force and poor machining accuracy; 3. Difficult installation, time-consuming assembly and disassembly, low labor productivity and high processing cost

Abstract

The invention discloses a clamp which comprises a body and a clamp assembly. The body is connected with a machine tool bolt through an assembly hole. The body is formed by a body base disc and a detachable body upper disc which are identical in structure and size. The clamp assembly is formed by two groups of clamp parts identical in structure and shape, and the two groups of clamp parts are symmetrically arranged on the body base disc concentric and opposite to the body. The clamping parts include a centrifugal rod, a resetting spring, a clamp head and a clamp head seat. The centrifugal rod is L-shaped, the clamp head seat is arranged at one end of the centrifugal rod and fixedly connected with the centrifugal rod, and the clamp head and the clamp head seat are detachably and fixedly connected. The clamp has the advantages of being reasonable in structure design, simple in manufacture process, capable of saving time and labor during assembly and disassembly, being proper in clamping force, high in machining accuracy, convenient to use and low in cost.

Description

technical field [0001] The invention relates to a fixture, which belongs to the technical field of mechanical processing. It is mainly used for turning and grinding of double-top shafts. Background technique [0002] The processing of shaft parts, especially double-top shaft parts, has relatively high requirements for fixtures. In the prior art, three screws and a heart-shaped chuck tooling are used for processing. This fixture structure has the following disadvantages: 1. Due to the vibration and rotation of the machine tool, the screws for clamping the shaft parts will loosen, and the work is unreliable; 2. Insufficient clamping force and poor machining accuracy; 3. Difficult installation, time-consuming assembly and disassembly, low labor productivity and high processing cost. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide "a clamp". The fixture has the advantages of reasonable stru...
