Pipe and column part butt weld polishing machine

Abstract

The invention relates to a pipe and column part butt weld polishing machine. The machine comprises a frame, a polishing mechanism and a part clamping, rotating and moving mechanism; the suspended self-aligning polishing mechanism is arranged on the frame in a suspension manner and comprises two suspension bracket assemblies with the same structure; the upper end part of each suspension bracket assembly is arranged on the frame in a hinging manner; each suspension bracket assembly comprises a suspension plate, a driving abrasive belt wheel, a driven abrasive belt wheel, an abrasive belt and a driving motor; each driven abrasive belt wheel is arranged on a tensioning plate; each tensioning plate is detachably and fixedly arranged at the lower end of the corresponding suspension plate; a telescopic clamping component and a lower rotary limiting mechanism are arranged between the two suspension bracket assemblies; two ends of the telescopic clamping component are respectively hinged to suspension plates; upper rotary limiting mechanisms for limiting the maximum opening angles of the two driven abrasive belt wheels are arranged above the two suspension bracket assemblies. The pipe and column part butt weld polishing machine has the advantages of simple structure, small size, convenience in installation and use, high grinding accuracy, long service life, low maintenance cost and the like.

Description

technical field [0001] The invention belongs to the technical field of butt weld processing machinery for pipe and column parts, in particular to a butt weld polishing machine for pipe and column parts. Background technique [0002] In the prior art, the butt weld grinding process of pipe and column parts is as follows: workers hold the pipe and column parts in their hands, and use a sander with a simple structure to perform manual sanding. The sander generally includes a sanding wheel, installed on The sanding belt on the sanding wheel and the motor that drives the grinding wheel to rotate have the following disadvantages in this manual sanding method: 1. The sanding quality is poor: the worker holds the tube and column parts, making the tube and column parts Friction occurs between the weld and the abrasive belt, and the force between the pipe and column parts and the abrasive belt and the sanding angle of the pipe and column parts are difficult to grasp, which seriously a...

[0002] In the prior art, the butt weld grinding process of pipe and column parts is as follows: workers hold the pipe and column parts in their hands, and use a sander with a simple structure to perform manual sanding. The sander generally includes a sanding wheel, installed on The sanding belt on the sanding wheel and the motor that drives the grinding wheel to rotate have the following disadvantages in this manual sanding method: 1. The sanding quality is poor: the worker holds the tube and column parts, making the tube and column parts Friction occurs between the weld and the abrasive belt, and the force between the pipe and column parts and the abrasive belt and the sanding angle of the pipe and column parts are difficult to grasp, which seriously affects the sanding quality; Pipe and column parts are polished at one time, and the sanding effect is not good

2. Low sanding efficiency: Affected by the fatigue strength and the working ability of workers, the work efficiency of manual hand-held tubes and column parts for sanding is low

3. There are potential safety hazards: in the process of grinding tube and column parts, once the workers get rid of their hands, the tube and column parts fly out, which is prone to production accidents

[0003] Several types of polishing equipment of this type are currently on the market, but they all have large volumes and many transmission parts, and fixed grinding is used when grinding parts, that is, the two grinding wheels are pushed towards the center by the cylinder until they are in contact with the parts. Contact, it will be fixed after contact, so that it can not be ground according to the appearance of the part floating and real-time, resulting in the grinding surface is not smooth, and even there are places where the grinding is not in place. In addition, the existing equipment has many spare parts. The places where problems occur in the actual operation process also increase accordingly, resulting in a higher repair rate of equipment, resulting in higher maintenance costs
