Abstract

The invention discloses a semi-automatic clamp for a lathe. Connecting rod supports are fixedly connected with two ends of a clamp body; a positioning block is mounted in the middle of the clamp body; positioning flat plates are fixed on the two sides of the positioning block; a slide seat and an arc briquette are arranged at the two ends of the positioning block; a foot margin type hydraulic cylinder is fixedly mounted on a hydraulic cylinder seat in the clamp body; connecting rod slide seat is arranged at the top of the hydraulic cylinder seat; supporting rods are arranged on two sides of the hydraulic cylinder seat; a piston rod of the hydraulic cylinder is hinged with a lug of the connecting rod slide seat through a threaded connecting rod; two rotary rods are connected with the supporting rods arranged on the two sides of the hydraulic cylinder seat; one end of each rotary rod is fixedly connected to the connecting rod slide seat; the other ends of the rotary rods are connected with middle connecting rods respectively; the middle connecting rods are respectively connected with push rods; and each of the push rods is fixedly connected with the connecting rod support at the two ends of the clamp body and the slide seat respectively. The clamp has the advantages of compact structure, reliable clamping performance and high universality; and the clamping is reasonable and fast, and a plurality of workpieces can be processed at the same time, which can not only improve the processing efficiency, but also relieve the work intensity of operators.

Description

technical field [0001] The invention relates to a fixture, in particular to a semi-automatic fixture for machine tools. It belongs to the technical field of mechanical design and tooling equipment. Background technique [0002] At present, in the mechanical processing industry at home and abroad, computer-aided fixture design (CAFD) is continuously applied to product process equipment and fixture design. It not only overcomes the shortcomings of traditional fixture design, reduces the labor intensity of designers, but also improves Quality of fixture design. Scholars at home and abroad have carried out a lot of research on CAFD technology. For example, using SolidWorks software as a platform, first establish a parametric solid model library for standard parts of fixtures, and then develop non-standard solid model libraries for different fixtures. After the three-dimensional solid model of the assembly is obtained through virtual assembly, the two-dimensional engineering dr...
