Automatic polishing machine

Abstract

The invention relates to an automatic polishing machine, comprising a base frame, the upper end of which is hung with a bracket that is connected with a beam of the base frame, a grinding wheel connected with the middle part of the bracket, a first flexible device which is horizontally arranged and one end of which is connected with a vertical column of the base frame and the other end is against the lower end of the bracket, a second flexible device which is vertically arranged and one end of which is connected with a bottom frame of the base frame, a transmission device which is connected with the other end of the second flexible device, a third flexible device which is horizontally arranged and one end of which is connected with the vertical column and the other end is connected with a top-supporting device which is used for supporting a top part together with the grinding wheel and the transmission device for product processing. The automatic polishing machine of the invention is suitable for processing tubes of various sizes and types, and is suitable for polishing tubes of irregular shapes with high polishing quality and low vibration noise when in working.

Description

technical field [0001] The invention relates to an automatic polishing machine, in particular to a device for automatically polishing the surface of a pipe. Background technique [0002] Polishing the surface of the product is a processing step usually required in the product processing process, especially for pipes made of metal materials such as stainless steel and cast iron. Most of the pipes need to be polished before the final molding or before surface coating and other steps. Since the polishing process is commonly used, the efficiency and effectiveness with which the polishing machine performs the polishing operation becomes an important factor affecting the production efficiency and quality of various products. [0003] Most of the existing pipe polishing machines are based on the principle of centerless polishing, and adopt the design of conveyor belt, adjustable fixed baffle or roller, and adjustable fixed grinding wheel, such as Figure 1A with 1B As shown, it in...

AI Technical Summary

Problems solved by technology

[0004] 1. Because the baffle or roller is fixed during the polishing process, it is often impossible to properly place the pipe against the grinding wheel. It may be too tight or too loose, resulting in uneven polishing on the surface of the pipe, and there is a specification error for the product to be processed Or in the case of polishing thin-skinned pipes, if the shape of the product changes slightly or the surface has unevenness, the polishing effect is more difficult to guarantee;

[0005] 2. The position between the baffle plate and the grinding wheel is difficult to adjust in a large range and accurately, which limits the adaptability of the polishing machine to products of various sizes to be processed. The adjustable range of the diameter of the round tube allowed by the existing polishing machine is generally within 70mm , the difference in length and width of the cross-sectional size of the opposite pipe is limited to less than 70mm;

[0006] 3. It is usually difficult for polishing machines to achieve polishing in a closed space, which will generate serious dust and noise pollution;

[0007] 4. The space occupied by the array of grinding wheels and the motor is relatively large, and multiple motors that drive the array of grinding wheels need to work at the same time, which consumes a lot of power
