Clamper clamping internal part of workpiece

Abstract

The invention discloses a clamping device, and particularly relates to a clamper clamping an internal part of a workpiece. The clamper clamping the internal part of the workpiece comprises a base seat and a positioning device arranged on the base seat, the positioning device comprises a clamping piece and a fixing piece, wherein the clamping piece is of a barrel-shaped structure, and the lower portion of the fixing piece is in threaded connection with the base seat. A cross through groove is arranged in the clamping piece. Compared with the prior art, the clamper clamping the internal part of the workpiece solves the problem that discarded clampers are inconvenient to replace in the prior art, and adopts a spilt structure design. The clamper clamping the internal part of the workpiece can be replaced conveniently due to the fact that the clamper body is in threaded connection with the base body, and at the same time different clamping pieces can be adopted according to different structures of the clamping pieces. Due to the fact that the clamping piece adopts the barrel-shaped structure and the cross through groove is arranged in the clamping piece, the clamper clamping the internal part of the workpiece achieves clamping of the workpiece by sleeving the clamping piece into the workpiece.

Description

[0001] technical field [0002] The invention relates to a clamping device, in particular to a clamp for clamping the inside of a workpiece. Background technique [0003] Clamping devices are widely used in the manufacturing industry. For example, during the stamping, riveting, welding, pasting or solidification of the workpiece, it is often necessary to maintain the correct positional relationship. Clamping devices have various datum surfaces or points that allow the workpiece to be positioned accurately and are therefore considered an essential component in the machining industry. [0004] In the industrial field, when we process the outside of the workpiece, we often need to clamp the inside of the workpiece for processing. For the existing fixtures, one-piece fixtures are often used. Although such fixtures have high stability, the Wear and tear is unavoidable in long-term repeated use, so it is necessary to replace the clamping parts irregularly. Contents of the inve...

[0004] In the industrial field, when we process the outside of the workpiece, we often need to clamp the inside of the workpiece for processing. For the existing fixtures, one-piece fixtures are often used. Although such fixtures have high stability, the In the long-term repeated use, wear is inevitable, so it is necessary to replace the clamping parts from time to time
