Thrust clamping device

Abstract

The invention discloses a thrust clamping device. The thrust clamping device comprises a base, a linkage mechanism and a boss which is used for clamping a shaft. A guide hole, a slide block, a cavity and a groove are formed or arranged in the base. The slide block is in slide connection with the guide hole. The linkage mechanism comprises a clamping jaw, a power rod, a linkage rod, a connection plate, a press plate and a threaded rod. The clamping jaw is hinged to the inner wall of the cavity. The power rod and the linkage rod are connected with the base in a slide mode. The connection plate is hinged to the base. The press plate is arranged in the groove. The threaded rod is fixedly connected with the press plate. One end of the clamping jaw is abutted against the power rod. The other end of the clamping jaw is hinged to the slide block. One end of the connection plate is hinged to the power rod. The other end of the connection plate is hinged to the linkage rod. The end, far away from the connection plate, of a linkage plate is connected with the press plate in a slide mode. A tension spring is arranged between the end, penetrating through the base, of the threaded rod and the base. The other end of the threaded rod is connected with a nut. The boss is arranged at the end, far away from the threaded rod, of the press plate. According to the scheme, the problems that an existing clamp for machining the shaft is complex in structure, tedious in operation and low in work efficiency are solved.

Description

technical field [0001] The invention relates to the field of clamps, in particular to a thrust clamping device. Background technique [0002] In a broad sense, any process in the process, the device used to install the workpiece quickly, conveniently and safely, can be called a fixture. Such as welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc. Among them, machine tool fixtures are the most common, often referred to as fixtures. When processing a workpiece on a machine tool, in order to make the surface of the workpiece meet the technical requirements such as the size, geometric shape, and position accuracy with other surfaces specified in the drawing, the workpiece must be installed and clamped firmly before processing. Fixtures are usually composed of positioning elements, clamping devices, tool setting guide elements, indexing devices, connecting elements, and clamp bodies. Jigs and fixture arrangements are well known and widely used ...

AI Technical Summary

Problems solved by technology

With the development of my country's national economy, the demand for shafts is also increasing. According to different needs, shafts need to be further processed. Therefore, the fixture used for processing shafts is extremely important. The existing fixtures usually have a complex overall structure and relatively difficult operation. It is cumbersome and reduces the work efficiency of shaft machining
