Hydraulic jig capable of rapidly switching clamping surfaces

Abstract

The invention discloses a hydraulic jig capable of rapidly switching clamping surfaces. The hydraulic jig comprises a base, a hydraulic pump arranged on the base, a hydraulic cylinder connected with the hydraulic pump, and a piston rod connected with a piston in the hydraulic cylinder. A vertical baffle is fixed to one end of the base. A sliding groove is formed in the upper surface of the base. A sliding block is placed in the sliding groove. A vertical rotating shaft is arranged on the sliding block and fixedly connected with a clamping plate. One surface of the clamping plate is a flat surface and the other surface of the clamping plate is a curved surface. According to the hydraulic jig capable of rapidly switching the clamping surfaces, the problem that a single jig cannot tightly clamp flat surfaces and curved surfaces at the same time in the prior art is solved, and the purpose of stabilizing a flat-surface workpiece or a curved-surface workpiece through the same jig is achieved.

Description

technical field [0001] The invention relates to the field of clamps, in particular to hydraulic clamps for quickly switching clamping surfaces. Background technique [0002] Fixture is a commonly used tool in the process of machining. It is a device used to fix the processing object in the process of mechanical manufacturing so that it can occupy the correct position for construction or inspection. It is used to fix the material or part to be processed, to ensure that it will not move and shift during the processing, and to avoid the deviation of the object to be processed from affecting the precision and accuracy of the processing operation. In a broad sense, in any process of the processing process, the device used to quickly, conveniently and safely install the workpiece can be called a fixture, such as welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc. Existing fixtures, except some special fixtures specially made for the processing of...

Problems solved by technology

[0004] The purpose of the present invention is to provide a hydraulic clamp with fast switching clamping surface, which solves the problem that a single clamp in the prior art cannot clamp both flat and curved surfaces, and achieves the purpose of stabilizing flat or curved workpieces with the same clamp

Aiming at the problem that the existing single clamp can not clamp both flat and curved surfaces, the present invention proposes a hydraulic clamp that quickly switches the clamping surface, through a clamping plate with one side being a plane and the other being a curved surface, and driving the clamping The rotating shaft of the holding plate can realize the convenient and fast replacement of the clamping surface, so as to achieve the purpose of stabilizing the flat workpiece or the curved surface workpiece with the same fixture
