Back chuck with dedusting function

Abstract

The invention relates to the field of clamping equipment, in particular to a back chuck with a dedusting function. The back chuck is provided with a bearing pedestal and comprises a front bearing anda back bearing arranged in the bearing pedestal, separately, a guide block hood, a chuck body, a connecting rod bracket, an air pumping assembly and an air outlet pipe, wherein the guide block hood isfixedly connected to the front end of the front bearing through a screw; an air cylinder assembly is arranged in the guide block hood; the chuck body is fixed to the front ends of a guide block assembly and the air cylinder assembly, and a clamping jaw assembly is driven by the air cylinder assembly; the connecting rod bracket is arranged between the chuck body and the air cylinder assembly, andthe connecting bracket is movably connected to the air cylinder assembly through a connecting rod; the air pumping assembly is arranged at the back end of a reducer assembly, and the air pumping assembly is supplied with gas by an external gas source and drives the air cylinder assembly; and the air outlet pipe penetrates the reducer assembly, the bearing pedestal, the air cylinder assembly and the chuck body. The clamping jaw provided by the invention is simple in structure and communicates to the external gas source by means of the air outlet pipe, so that fragments and dust are blown away / extracted during processing, and therefore, dust pollution of the environment is avoided.

Description

technical field [0001] The invention relates to the field of clamping equipment, in particular to a rear chuck with a dust removal function. Background technique [0002] Laser cutting is the most important application technology in the laser processing industry. Due to its fast speed, high precision, and no deformation of the workpiece, it has been widely used in automobiles, rolling stock manufacturing, aviation, chemical industry, and light industry. , electrical appliances and electronics, petroleum and metallurgy and other fields. In recent years, laser cutting technology has developed rapidly, with an annual growth rate of 20% to 30% internationally. The broad application market of laser cutting processing, coupled with the rapid development of modern science and technology, has made domestic and foreign scientific and technological workers conduct continuous research on laser cutting processing technology, and promote the continuous development of laser cutting techn...

Problems solved by technology

[0003] With the increasing market of laser pipe cutting machines, more and more pneumatic chucks are used. However, the pneumatic chucks currently used by laser machine factories generally have a problem that there is a lot of tailings and it is impossible to remove the dust inside the clamped pipe body.

The clamped pipe body usually produces a lot of debris and dust during processing, resulting in environmental dust pollution
