Problems solved by technology

[0003] The invention provides a polishing wheel with simple structure, uniform polishing, no need to rotate the pipe to be processed, high efficiency, and capable of processing variable-diameter pipes; it solves the uneven polishing of the polishing wheel in the prior art, and it can be polished while polishing It is necessary to rotate the pipe, which is time-consuming and labor-intensive, and the technical problem of low production efficiency
[0004] At the same time, the invention also provides an inner wheel that can be adapted to various specifications, so that steel pipes with different diameters can be polished, and the polishing wheel can be easily disassembled, which solves the problem that the polishing wheel in the prior art can only be used for a single diameter. The pipes are polished, the versatility is not good, and the technical problems are high cost

Embodiment 1

[0035] like figure 1 As shown, a polishing wheel includes an inner wheel 1 , a nest 2 and an outer wheel 3 that rotate synchronously and are coaxial. There are four evenly distributed arc-shaped elastic grinding members 4 in the inner wheel 1, one end of the four elastic grinding members 4 is connected to the inner wall of the inner wheel 1, and the other end is at the same distance from the center of the inner wheel 1, The diameter of the processing inner circle 5 formed by four end points is slightly smaller than the diameter of the pipe to be ground (such as figure 2 shown), the elastic grinding member 4 can be elastically deformed according to the change of the diameter of the pipe to be ground.

[0036] like image 3 As shown, the diameter of the middle part of the outer wheel 3 is greater than the diameters of both ends, and a V-shaped belt groove 6 is provided on the outer peripheral surface of the middle part, which is used for connecting the belt transmission syste...

Embodiment 2

[0047] like Figure 17 As shown, a polishing wheel includes an inner wheel 1 , a nest 2 and an outer wheel 3 that are coaxial and rotate synchronously. The difference from Embodiment 1 is that there is no annular cover plate 7 in this embodiment, and the outer circumferential surface of the inner wheel 1 is evenly distributed with four protrusions 11 integrally formed with the inner wheel through clearance fit and positioning on the nesting. The groove 10 is matched, the length of the protrusion 11 is the same as the length of the positioning groove 10, the positioning key 9 on the outer circumferential surface of the nesting 2 is clearance fit with the groove 8 on the inner wall of the outer wheel, and the length of the positioning key 9 is the same as the length of the groove 8 . When assembling, insert the inner wheel into the nest, and the two are closely matched. Similarly, insert the nest with the inner wheel into the outer wheel, so that the three are tightly matched a...

Abstract

The invention relates to a grinding component, in particular to a polishing wheel for grinding a pipe. The polishing wheel comprises an outer wheel and an inner wheel, wherein the outer wheel and the inner wheel are coaxial, are connected with each other and rotate synchronously. An inner wall of the inner wheel is provided with more than two elastic grinding components, the elastic grinding components are arc-shaped, one ends of the elastic grinding components are connected with the inner wall of the inner wheel, endpoints of the other ends of the elastic grinding components are located on an identical circle, and the outer wheel is provided with a linkage part. The polishing wheel is simple in structure, performs polishing evenly, is high in efficiency and can be used for processing the diameter-varied pipe, and the to-be-processed pipe does not need rotating. The technical problems that in the prior art, the polishing wheel cannot perform polishing evenly, the pipe needs rotating in the polishing process, time and labor are wasted, and production efficiency is low are solved.

Description

technical field [0001] The invention relates to a grinding component, in particular to a polishing wheel for grinding pipes. Background technique [0002] In the process of pipe production, the polishing of the outer surface of the pipe is a very important process. The common practice in the industry is to put the pipe close to the rotating polishing wheel and rotate the pipe at the same time to meet the technical requirements of surface polishing. If the pipes are polished in the traditional way, the polishing of the product will be very uneven, which requires higher technical requirements for workers and consumes more manpower. In the existing patent documents, a Chinese patent is disclosed: "Polishing Wheel for Polishing Machine (CN2732419Y)". The polishing wheel includes a wheel frame and a rubber ring. The long strip is provided with an annular belt surrounding the wheel frame, and the outer edge of the wheel frame is covered with a rubber ring. Chinese patent: "a pol...
