Clamping and fixing device for metal processing

Abstract

The invention relates to the technical field of metal processing, and discloses a clamping and fixing device for metal processing. The device comprises an operating table, the upper surface of the operating table is fixedly connected with a sliding rail and a limiting ring separately, the upper surface of the operating table is rotatably connected with a fluted disc, and the left end of the innerwall of the sliding rail is fixedly connected with an electromagnet; and a metal sliding block is slidably connected to a grooved rail of the sliding rail, and a rack is fixedly connected to the end,close to the fluted disc, of the metal sliding block. According to the clamping and fixing device for metal machining, when a clamping block abuts against a metal material, a sleeve rod continues to move under driving of the fluted disc, a spring rod starts to be compressed, a switch assembly in the spring rod is in abut joint, a circuit is closed, an electrorheological fluid is powered on to be in a solid state, and a guide rod cannot move in a box body; and a limiting block fixedly connected with the guide rod cannot move, so that a push rod is limited under the matching of the limiting block and saw teeth, the push rod and the clamping block cannot move, and the effect of more stable clamping is achieved.

Description

technical field [0001] The invention relates to the technical field of metal processing, in particular to a clamping and fixing device for metal processing. Background technique [0002] Metal processing, referred to as metalworking, is a process technology that processes metal materials into parts, components or decorations. It is widely used in different fields such as industry, handicrafts and artworks. [0003] When drilling, cutting or grinding metal, it needs to be fixed first. At present, when processing some metal materials with small volume, workers usually hold processing equipment and metal materials for processing. During the processing The metal material may shift or fall off due to the negligence of workers, which will affect the processing effect, and the processing equipment may cause damage to the hands holding the metal material; when processing some larger metal materials, it will be used Clamping and fixing devices, such as three-jaw chucks, etc., althou...
