Automatic polishing and milling machine

Abstract

The invention relates to an automatic polishing machine, comprising: a base frame; a bracket whose upper end rotating shaft is suspended and connected to the beam of the base frame and is horizontally slidably connected with respect to the beam; the middle part of the bracket is connected with a grinding wheel; A second telescopic device installed vertically on the frame base; the other end of the second telescopic device is connected with a transmission device for transporting products to be processed; one end of the second telescopic device is connected to the column and arranged horizontally; The other end of the third telescopic device is connected with a resisting device, which is used to cooperate with the grinding wheel and the conveying device to resist the product to be processed. The automatic polishing machine of the present invention adopts the suspended bracket and the grinding wheel to realize the constant force contact of the product to be processed, and can realize automatic centering, and can be suitable for processing pipes of various sizes and types, and is suitable for irregular shapes Polishing is performed, the quality of polishing is high, and the vibration and noise are small during operation.

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 that is usually required in the product processing process, especially for pipes made of metal materials such as stainless steel and cast iron. deal with. 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 includes the following structures: an array of grinding wheels 200 driven by an independ...

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, making the surface of the pipe uneven in polishing. In the case of specification errors or polishing of 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 pipe allowed by the existing polishing machine is generally within Within 70mm, the difference in length and width of the cross section of the opposite pipe is limited to less than 70mm;

[0006] 3. It is usually difficult for a polishing machine 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
