Problems solved by technology

[0005] This bowl-shaped workpiece clamping device with a hole in the bottom is mainly fixed by the relative movement between the piston rod 1, the driving column wedge 2, the two plungers 4, the return spring 6, and the fixing of the positioning screw 5 and the compression nut. The connection realizes the clamping of the workpiece, and its overall structure is more complicated and its working principle is more complicated

Abstract

The invention relates to the field of clamping devices, in particular to an arc type clamping device. The arc type clamping device comprises a base, a positioning block, a stud, nuts and a clamping portion. The base comprises an upper base body and a lower base body. The positioning block is clamped to the upper surface of the upper base body. A workpiece is placed on the upper surface of the lower base body. The stud penetrates the positioning block to reach the lower base body and is arranged in the lower base body. The upper end of the stud is fixed to the upper surface of the positioning block through one nut. The lower end of the stud is fixed to the upper surface of the lower base body through another nut. The clamping portion is arranged on the lower surface of the upper base body and clamps the lower end of the positioning block and the stud. The other end of the clamping portion abuts against the workpiece. The clamping portion is matched with the lower surface of the upper base body, the lower end of the positioning block and the contact face of the stud. The arc type clamping device is simple in structure and simple in working principle.

Description

technical field [0001] The invention relates to the field of clamping devices, in particular to an arc type clamping device. Background technique [0002] The device used to fix the processing object in the process of mechanical manufacturing so that it occupies the correct position to accept construction or inspection, also known as fixture. 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 machining 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 positioned and clamped before processing. [0003] In the existi...
