Description

Technical Field

[0001] The invention relates to the technical field related to roller grinding, and in particular to a grinding and polishing device for roller grinding. Background Art

[0002] In the modern industrial manufacturing process, grinding and polishing of pipes are crucial steps, which directly affect the appearance quality, performance and service life of the product. Traditional methods of grinding and polishing pipes mostly rely on manual operation or simple mechanical equipment. These methods are not only inefficient, but also difficult to ensure the consistency of the surface quality of the processed pipes. Especially when processing pipes of different diameters, tools need to be frequently replaced or adjusted, which increases the difficulty of operation and production costs.

[0003] With the development of automation technology, some roller grinding equipment has appeared on the market, aiming to improve the grinding and polishing efficiency of pipes through rotating grinding wheels and other auxiliary components. However, the existing roller grinding equipment has obvious technical defects, which are mainly manifested in the following aspects:

[0004] 1. Poor adaptability: Traditional equipment is usually designed for pipes within a specific diameter range. When faced with pipes of different diameters, it is necessary to stop the machine for adjustment or replacement of accessories, which greatly reduces production efficiency and increases operational complexity.

[0005] 2. Insufficient uniformity: Due to the mismatch between the driving wheel and the contact surface of the pipe, the grinding pressure of the grinding wheel on the pipe surface is unevenly distributed, which in turn affects the uniformity of grinding and polishing, making it difficult for the surface quality of the final product to reach high standards.

[0006] In view of the above technical defects, the present invention proposes, for this purpose, we propose a grinding and polishing equipment for roller grinding. Summary of the invention

It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0037] See also Figure 1 - Figure 7 The embodiment of the present invention provides a technical solution: a grinding and polishing device for roller grinding, comprising an operating table 1, a grinding wheel 13 is arranged in the operating table 1, a plurality of evenly distributed driving wheels 12 are arranged in the operating table 1, a driven shaft 23 is fixedly installed at the lower end of each driving wheel 12, a movable sleeve 2 is rotatably installed on the outer periphery of the driven shaft 23, a first rotating rod 21 and a second rotating rod 22 are rotatably installed on both sides of each movable sleeve 2, a first rotating seat 211 rotatably connected to the other end of the first rotating rod 21 is fixedly installed on the inner wall of the operating table 1, a driven gear ring 242 is rotatably installed in the operating table 1, and a driven gear ring 242 is rotatably installed in the operating table 1.

[0038] Working principle: When in use, the pipe fitting is inserted into the operating table 1, and the first driving motor 24 is started. Through the meshing connection between the driving gear 241 and the driven gear ring 242, the first driving motor 24 can drive the driven gear ring 242 to rotate through its output shaft. Under the restriction of the movement direction of the movable sleeve 2 through the rotation connection between the first rotating rod 21 and the first rotating seat 211 of the operating table 1, the rotating driven gear ring 242 can drive each driving wheel 12 to shrink inward to fit with the outer periphery of the pipe fitting through the rotation connection between the second rotating rod 22 and the second rotating seat 221 and the movable sleeve 2, so as to achieve the effect of positioning the pipe fitting;

[0039] During the movement of each movable sleeve 2, the spring 36 and the tensioning wheel 33 ensure that the transmission belt 3 is always in contact with the outer periphery of the tensioning wheel 33, the driving wheel 32 and each driven shaft 23;

[0040] Then, the second drive motor 31 is started, and through the connection effect between the transmission belt 3 and the tensioning wheel 33, the driving wheel 32 and the periphery of each driven shaft 23, the second drive motor 31 can drive each drive wheel 12 to rotate through its output shaft, thereby achieving the effect of rotating the pipe fitting;

[0041] Finally, the pipe fitting can be polished and ground by the grinding wheel 13 .

[0042] In another embodiment provided by the present invention, a connecting seat 34 is rotatably installed on the outer side of the tensioning wheel 33, and a spring 36 is fixedly installed between the connecting seat 34 and the inner wall of the operating table 1; a telescopic sleeve 35 is fixedly installed between the connecting seat 34 and the inner wall of the operating table 1, and the spring 36 is arranged in the telescopic sleeve 35.

[0043] Specifically, the movement direction of the connecting seat 34 can be limited inside the operating table 1 through the telescopic sleeve 35, and the movement direction of the tensioning wheel 33 can be limited through the connecting seat 34, thereby ensuring that the tensioning wheel 33 is always in contact with the transmission belt 3.

[0044] In another embodiment provided by the present invention, a protective cover 11 is plugged and installed on the upper end of the operating table 1, and a hydraulic push rod 4 is fixedly installed on the inner wall of the operating table 1; a connecting plate 41 is fixedly installed on the inner end of the hydraulic push rod 4 through its output shaft, a third drive motor 42 is fixedly installed in the connecting plate 41, and a grinding wheel 13 is arranged at the outer end of the output shaft of the third drive motor 42; a limiting plate 43 is fixedly installed on the upper end of the third drive motor 42 through its output shaft, a positioning gear rod 44 is fixedly installed on the upper end of the limiting plate 43, a positioning gear hole 45 is opened in the middle of the grinding wheel 13, and the positioning gear hole 45 and the positioning gear rod 44 are plugged into each other; a threaded curved groove 46 is opened on the periphery of the positioning gear rod 44, a limiting rotation chamber 47 connected to the positioning gear hole 45 is opened on the upper end of the grinding wheel 13, and a threaded ring 48 threadedly connected to the threaded curved groove 46 is rotatably installed in the limiting rotation chamber 47.

[0045] Specifically, a protective cover 11 is provided to block the flying metal debris when the pipe is polished and processed, thereby protecting the workers;

[0046] When the pipe fitting needs to be processed by the grinding wheel 13, the hydraulic push rod 4 is started to adjust the position of the grinding wheel 13 so that the grinding wheel 13 contacts the outer periphery of the pipe fitting, and then the third driving motor 42 is started to drive the grinding wheel 13 to rotate through its output shaft, so as to achieve the effect of grinding and polishing the pipe fitting;

[0047] When the grinding wheel 13 needs to be replaced according to the requirements of pipe grinding and polishing, the grinding wheel 13 can be installed on the upper end of the positioning gear rod 44 through the plug-in connection between the positioning gear rod 44 and the positioning gear hole 45. When the threaded ring 48 contacts the positioning gear rod 44, the threaded ring 48 is rotated, and the grinding wheel 13 is driven to move through the threaded connection between it and the threaded curved groove 46, thereby achieving the effect of positioning the grinding wheel 13. Otherwise, the grinding wheel 13 can be disassembled, thereby achieving the effect of replacing the grinding wheel 13.
