Conical pipe weld joint trimming device

Abstract

The invention discloses a conical pipe weld joint trimming device and belongs to the technical field of weld joint trimming. The device comprises a base. Conical pipe clamping mechanisms of the same structure are arranged at the tops of the two first T-shaped sliding blocks correspondingly. An annular piece is welded to the outer wall of the left side of an annular ring. A rotary inner gear ring is arranged at the inner side of the annular piece; the top of the outer wall of the left side of the rotary inner gear ring is connected with a supporting block through two groups of connecting rods;a grinding cooling mechanism matched with a grinding block is arranged at the top of a movable assembly block; and a dust collection mechanism is arranged on the inner wall of the annular ring. Conical pipes of different specifications can be conveniently clamped; the rotary inner gear ring is driven to rotate through cooperation of a second micro servo motor, a speed reducer and a small gear, then, a trimming mechanism is driven to rotate through the connecting rods to trim the weld joint, so that the working efficiency and the working quality are greatly improved; and meanwhile, the trimming device is flexible and convenient to use, and adapts to weld joint trimming operation of conical pipes of different specifications.

Description

technical field [0001] The invention relates to the technical field of welding seam trimming, in particular to a welding seam trimming device for tapered pipes. Background technique [0002] Tapered pipe refers to a tapered seamless pipe designed and manufactured with seamless steel pipe as raw material through special equipment and technology. At present, when the length of the tapered pipe does not meet the requirements, two sets of matching tapered pipes Welding together, the weld seam at the welding place is prone to unevenness, so the weld seam needs to be trimmed by a trimming device. [0003] The current tapered pipe weld trimming devices on the market have the following defects: 1. Low trimming efficiency and low trimming quality. The welding seam on the surface is trimmed, and the flexibility is poor; 2 does not have a cooling mechanism and a dust suction mechanism, so that the conical tube is easily damaged due to temperature during the trimming, or dust affects t...

[0003] The current tapered pipe weld trimming devices on the market have the following defects: 1. Low trimming efficiency and low trimming quality. The welding seam on the surface is trimmed, and the flexibility is poor; 2 does not have a cooling mechanism and a dust suction mechanism, so that the conical tube is easily damaged due to temperature during the trimming, or dust affects the working environment and the health of the staff. For this reason, We propose a device for dressing of tapered pipe welds
