Composite tube end surfacing layer weld joint polishing equipment

Abstract

The invention discloses composite tube end surfacing layer weld joint polishing equipment which comprises a rack, a base, a polishing mechanism arranged on the rack and a polishing feeding mechanism arranged between the rack and the base; the polishing mechanism comprises a drive shaft, a variable frequency motor, an upper belt wheel, one end of the drive shaft is in cup joint with a lower belt wheel, the upper belt wheel and the lower belt wheel are connected through a belt, and the other end of the drive shaft is in cup joint with a grinding wheel and a contour wheel; the polishing feeding mechanism comprises a left-right feeding mechanism body, a front-rear feeding mechanism body and a linkage mechanism, a polishing fixing plate is hinged to the rack, and the drive shaft penetrates through the polishing fixing plate to be connected with the rack. The tube end surfacing layer weld joint polishing equipment is reasonable in structural design and convenient and fast to use, movement of the rack in the front-rear direction and the left-right direction is achieved through the arranged polishing feeding mechanism, the problem of circumferential jump of a steel pipe is solved through the arranged linkage mechanism, the problem of transition polishing of a grinding wheel can be effectively solved through the arranged grinding wheel and the contour wheel, and thus polishing precision and efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a welding seam grinding equipment for a cladding layer of a composite pipe end. Background technique [0002] Bimetal composite pipe usually puts a corrosion-resistant metal pipe inside another metal pipe, and fixes the two into one structure through expansion and end welding. There is an irregular transition step at the overlap of the welding layer. In order not to affect the subsequent use of the steel pipe, the step must be ground smoothly. The traditional grinding method is mostly manual grinding, and manual grinding mostly relies on the experience of workers to judge Grinding degree, this kind of grinding method has defects such as high grinding cost, low grinding precision, and long grinding time. Grinding existing defect, there is special grinding equipment on the market, but existing grinding equipment all exists and can't overcome the beating pr...

[0002] Bimetal composite pipe usually puts a corrosion-resistant metal pipe inside another metal pipe, and fixes the two into one structure through expansion and end welding. There is an irregular transition step at the overlap of the welding layer. In order not to affect the subsequent use of the steel pipe, the step must be ground smoothly. The traditional grinding method is mostly manual grinding, and manual grinding mostly relies on the experience of workers to judge Grinding degree, this kind of grinding method has defects such as high grinding cost, low grinding precision, and long grinding time. There are special grinding equipment on the market, but the existing grinding equipment cannot overcome the beating problem caused by the ellipticity and straightness of the steel pipe during the rotation process.
