[0002] External cylindrical grinder is a grinding machine used to process the outer surface of cylindrical, conical or other shaped workpieces and the shoulder end face. External cylindrical grinder can process various cylindrical and conical outer surfaces and shoulder end faces. Among all grinding machines, external cylindrical grinder is the most widely used type of machine tool.

[0003] In the prior art, an external cylindrical grinder with automatic loading and unloading is disclosed with announcement number CN215547269U, which includes a bed, a workbench is provided on the top surface of the bed, a headstock is provided at the left end of the top surface of the workbench, a chuck is installed on the headstock, a tailstock is provided at the right end of the top surface of the workbench, a hydraulic cylinder is installed in the tailstock, and a pointed top fixing block is installed at the output end of the hydraulic cylinder. The top surface of the bed is located behind the workbench and is provided with a driving mechanism, a grinding wheel frame is provided on the driving mechanism, the driving mechanism drives the grinding wheel frame to move back and forth, and a grinding wheel is rotatably installed on the side of the grinding wheel frame. A frame is provided on the top surface of the bed, an electric slide is installed on the frame, and a loading and unloading robot is installed on the slider of the electric slide. The electric slide drives the loading and unloading robot to move left and right. The structure of this utility model is simple and reasonable. Through the setting of the electric slide and the loading and unloading robot, automatic loading and unloading of workpieces is realized, labor costs are reduced, and production efficiency is increased.

[0004] However, although the existing automatic loading and unloading external cylindrical grinder can be used to automatically load and unload the processed products by means of a robotic arm, the grinding wheel needs to rotate at high speed when the grinder is used, and the conversion and recovery effect of the mechanical energy generated by the rotation of the grinding wheel is not high, and the energy loss of the grinder is not high. The filtering and recovery effect of the heat generated by the grinding wheel is not high. When recovering the heat, the surface preheating effect of the processed product is not good, resulting in a large temperature difference between the processed product and the surface of the grinding wheel, which reduces the quality of the product grinding. At the same time, the effect of simultaneously cooling the surface of the grinding wheel while blowing away impurities on the surface of the grinding wheel is not high, which easily causes large thermal stress on the surface of the grinding wheel, affecting the quality of the product grinding and not meeting people's use needs. For this reason, we propose an automatic loading and unloading external cylindrical grinder. Summary of the Invention

[0048] like Figure 4 As shown, the energy storage battery 16 provides electric energy for the electric blowing fan 22 and the electric suction blower arranged inside the recovery pipe 17, which is beneficial for providing electric energy for the electric blowing fan 22 and the electric suction blower arranged inside the recovery pipe 17 through the energy storage battery 16, thereby achieving the effect of converting and recycling the mechanical energy generated by the grinding wheel, and reducing the energy loss of the grinder under long-term use.

[0049] like Figure 8 As shown, the electrostatic dust removal component includes a negative roller 27 and a positive plate 28.

[0050] like Figures 9-13 As shown, a servo motor 30 is provided on the outer wall of the processing frame 6, and the output end of the servo motor 30 is fixedly connected to a connecting gear 31, and the outer wall of the connecting gear 31 is meshed with a connecting tooth plate 32, and the outer wall of the connecting tooth plate 32 is fixedly connected to a connecting rod 33 that is slidably connected to the outer wall of the processing frame 6, and one end of the connecting rod 33 is fixedly connected to a cleaning scraper 34, which is beneficial to achieve the effect of conveniently scraping and cleaning impurities on the surface of the grinding wheel 7 through the setting of the cleaning scraper 34.

[0051] like Figure 10As shown, an air storage chamber 35 is provided inside the cleaning scraper 34, a flow port 36 is provided on the outer wall of the cleaning scraper 34, an air pipe 37 is provided on the top of the cleaning scraper 34, one end of the air pipe 37 is fixedly connected to a connecting pipe 39, and the outer wall of the connecting pipe 39 is fixedly connected to a bellows 38, and an electric cooling fan 40 is provided inside the bellows 38, which is conducive to achieving the effect of synchronous blowing and synchronous cooling of impurities on the surface of the grinding wheel 7 through the arrangement of the electric cooling fan 40 and the air pipe 37. When the grinding wheel is grinding the product, the dust adsorbed on the surface is scraped and dust removed and the synchronous blowing and cooling movement is performed. The drive of the servo motor 30 drives the connecting gear 31 through the rotation of the connecting gear 31. The connecting rod 33 fixedly connected to the gear plate 32 slides along the outer wall of the processing frame 6, so that the cleaning scraper 34 is in contact with the surface of the grinding wheel disc 7, and under the rotation of the connecting gear 31, the sealing plate 42 is driven to flip through the rotation of the rotating shaft 41, so that the connecting pipe 39 is in an open state.

[0054] Working principle:

[0055] like Figure 1-13 As shown, when the cylindrical grinder is in use, firstly, in view of the characteristics of the grinding wheel on the grinding machine grinding the product for a long time, the mechanical energy generated by the long-term rotation of the grinding wheel is converted and recovered, thereby improving the versatility of the grinding wheel during rotation and reducing the energy loss rate of the cylindrical grinder during use. In addition, according to the heat characteristics generated by the grinding wheel during grinding, the generated heat is filtered and recovered, and the upper and lower sides of the product to be processed are preheated to prevent the temperature difference between the product surface and the grinding wheel surface, which will reduce the quality of the product grinding process.

[0056] Next, when the heat generated by the grinding wheel is recovered and used, the dust and debris in the heat are removed by the electrostatic dust removal component in the dust removal box 18, so that when the product is preheated, the surface cleanliness of the preheated product is improved and the product is prevented from having potholes during the grinding process;

[0057] Finally, the grinding wheel performs a scraping and dust removal motion and a synchronous purging and cooling motion to remove the dust adsorbed on the surface of the product during grinding processing. The servo motor 30 drives the connecting rod 33 fixedly connected to the connecting tooth plate 32 to slide along the outer wall of the processing frame 6 through the rotation of the connecting gear 31, so that the cleaning scraper 34 is in contact with the surface of the grinding wheel disc 7, and under the rotation of the connecting gear 31, the sealing plate 42 is driven to perform a flipping motion through the rotation of the rotating shaft 41, so that the connecting pipe 39 is in an open state. At the same time, under the drive of the electric cooling fan 40 by the energy storage battery 16, cold air is transported to the air storage chamber 35 through the delivery pipe 37 and blown to the surface of the grinding wheel disc 7 through the flow port 36, so as to achieve the effect of synchronously purging impurities on the surface of the grinding wheel disc 7 and synchronously cooling the grinding wheel disc 7, thereby preventing the surface heat of the grinding wheel from being too high and reducing the quality of the product grinding processing.

[0058] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make some changes or modifications to equivalent embodiments using the technical contents disclosed above.
