Description

Technical Field

[0001] This invention relates to the field of cylindrical grinding machine technology, and more specifically, to an automatic loading and unloading cylindrical grinding machine. Background Technology

[0002] External cylindrical grinding machines are grinding machines used to process the outer surfaces of cylindrical, conical, or other shaped workpieces, as well as the end faces of shaft shoulders. They can process various cylindrical and conical outer surfaces and end faces of shaft shoulders. Among all grinding machines, external cylindrical grinding machines are the most widely used type of machine tool.

[0003] In the prior art, a cylindrical grinding machine with automatic loading and unloading is disclosed in CN215547269U. It includes a bed, a worktable on the top surface of the bed, a headstock on the left end of the top surface of the worktable with a chuck mounted on it, a tailstock on the right end of the top surface of the worktable, a hydraulic cylinder inside the tailstock, and a pointed fixing block mounted on the output end of the hydraulic cylinder. A drive mechanism is located behind the worktable on the top surface of the bed, and a grinding wheel frame is mounted on the drive mechanism. The drive mechanism drives the grinding wheel frame to move back and forth. A grinding wheel is rotatably mounted on the side of the grinding wheel frame. A frame is located on the top surface of the bed, and an electric slide is mounted on the frame. A loading and unloading robot is mounted on the slider of the electric slide, and the electric slide drives the loading and unloading robot to move left and right. This utility model has a simple and reasonable structure. Through the setting of the electric slide and the loading and unloading robot, it realizes automated loading and unloading of workpieces, reduces labor costs, and increases production efficiency.

[0004] However, while existing automated cylindrical grinding machines can effectively load and unload products using robotic arms, the high-speed rotation of the grinding wheel during operation results in poor energy conversion and recovery, ineffective reduction of energy consumption, and inefficient heat filtration and recovery. Furthermore, the preheating of the product surface during heat recovery is inadequate, leading to a large temperature difference between the product and the grinding wheel, thus reducing the quality of the grinding process. Simultaneously, the simultaneous cleaning and cooling of the grinding wheel surface is ineffective, easily causing high thermal stress and affecting the grinding quality, failing to meet user needs. Therefore, we propose an automated cylindrical grinding machine with automatic loading and unloading. Summary of the Invention

[0005] To address the problems mentioned in the background, this invention provides an automatic loading and unloading cylindrical grinding machine, which solves the problems mentioned in the background art regarding low energy consumption of the grinding machine, poor preheating effect on the surface of the product to be processed, and low simultaneous cooling effect on the surface of the grinding wheel while cleaning impurities.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0008] The end of the connecting shaft is fixedly connected to a first locking block, the outer wall of the first locking block is engaged with a second locking block, the outer wall of the second locking block is fixedly connected to a generator shaft, one end of the generator shaft is provided with a generator body, the outer wall of the generator body is provided with a connecting line, and one end of the connecting line is fixedly connected to an energy storage battery provided on the outer wall of the sliding rod.

[0009] A recovery pipe is fixedly connected to the outer wall of the processing frame, a dust collection box is fixedly connected to the outer wall of the recovery pipe, and a diversion pipe is fixedly connected to the outer wall of the recovery pipe. One end of the diversion pipe is fixedly connected to an upper preheating box, and the other end of the diversion pipe is fixedly connected to a lower preheating box. A grid plate is fixedly connected to the side wall of the processing table, and the product body is placed on the surface of the grid plate. This system addresses the characteristics of prolonged grinding of products by the grinding wheel on the grinding machine, converting and recovering the mechanical energy generated during the long-term rotation of the grinding wheel. This improves the multi-functionality of the grinding wheel during rotation and reduces the energy consumption rate of the cylindrical grinding machine during use. Furthermore, based on the heat characteristics generated during grinding, the generated heat is filtered and recovered. Preheating is also performed on the upper and lower sides of the product to be processed to prevent temperature differences between the product surface and the grinding wheel surface, thus ensuring the quality of the product grinding process.

[0010] Preferably, the outer wall of the sliding frame is fixedly connected to a first electric push rod that is fixedly connected to the outer wall of the sliding rod, and the outer wall of the generator shaft is provided with a second electric push rod, one end of which is fixedly connected to a protective sleeve that is slidably connected to the outer wall of the generator shaft.

[0011] Preferably, the inner wall contour of the protective sleeve is adapted to the outer wall contour of the connecting shaft and the generator shaft, and the first and second locking blocks are staggered with each other.

[0012] Preferably, the upper preheating box is equipped with an electric fan, and the bottom of the upper preheating box is fixedly connected to a flow grid plate located above the product body;

[0013] The main body of the product is located in the middle of the upper preheating box and the lower preheating box. An electric suction fan is installed inside the recovery pipe. An electrostatic dust removal component is installed inside the dust removal box. A loading and unloading robotic arm is slidably connected to the outer wall of the grinding machine body.

[0014] Preferably, the energy storage battery provides power to the electric blower and the electric suction fan installed inside the recycling pipe.

[0015] Preferably, the electrostatic dust removal assembly includes a negative electrode roller and a positive electrode plate. The dust removal box contains a negative electrode roller, and a positive electrode plate is located on one side of the negative electrode roller. The dust removal box also contains an activated carbon adsorption mesh located on one side of the positive electrode plate. When recovering and using the heat generated by the grinding wheel, the electrostatic dust removal assembly in the dust removal box removes dust and debris from the heat, thereby improving the surface cleanliness of the preheated product and preventing pits from appearing during the grinding process.

[0016] Preferably, a servo motor is installed on the outer wall of the processing frame. A connecting gear is fixedly connected to the output end of the servo motor. A connecting toothed plate meshes with the outer wall of the connecting gear. A connecting rod that is slidably connected to the outer wall of the processing frame is fixedly connected to the outer wall of the connecting toothed plate. A cleaning scraper is fixedly connected to one end of the connecting rod. When the grinding wheel grinds the product, it scrapes away the dust adsorbed on the surface and performs a simultaneous blowing and cooling motion. Driven by the servo motor, the connecting gear rotates, causing the connecting rod fixedly connected to the connecting toothed plate to slide along the outer wall of the processing frame, so that the cleaning scraper comes into close contact with the surface of the grinding wheel. Under the rotation of the connecting gear, the rotating shaft rotates, causing the sealing plate to flip, so that the connecting pipe is in an open state. At the same time, driven by the energy storage battery to the electric cooling fan, cold air is delivered to the air storage chamber through the delivery pipe and blown onto the surface of the grinding wheel through the flow port, achieving the effect of simultaneously blowing away impurities on the surface of the grinding wheel and simultaneously cooling the grinding wheel, thus preventing the surface of the grinding wheel from getting too hot and reducing the grinding quality of the product.

[0017] Preferably, the cleaning scraper has an air storage chamber inside, a flow port on the outer wall of the cleaning scraper, an air supply pipe on the top of the cleaning scraper, a connecting pipe fixedly connected to one end of the air supply pipe, a wind box fixedly connected to the outer wall of the connecting pipe, and an electric cooling fan inside the wind box.

[0018] Preferably, the rotation center of the connecting gear is fixedly connected to a rotating shaft, and one end of the rotating shaft is fixedly connected to a sealing plate that is rotatably connected to the inner wall of the connecting pipe.

[0019] Preferably, the energy storage battery provides power to the electric cooling fan, and the flow port is in contact with the surface of the abrasive disc.

[0020] Compared with the prior art, the beneficial effects of this invention are as follows:

[0021] 1. This invention addresses the characteristics of grinding wheels on grinding machines grinding products for extended periods.

Furthermore, based on the heat characteristics generated during grinding, the invention filters and recovers the generated heat and preheats the upper and lower sides of the product to be processed to prevent temperature differences between the product surface and the grinding wheel surface, thus ensuring the quality of the grinding process.

[0022] 2. By setting up a dust collection box, the present invention enables the recovery and reuse of heat generated by the grinding wheel.

[0023] 3. The cleaning scraper and air supply pipe of this invention enable the grinding wheel to scrape away dust adsorbed on the surface of the product during grinding.

[0039] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0040] Example 1:

[0041] Please see Figures 1 to 13This embodiment provides an automatic loading and unloading cylindrical grinding machine, including a grinding machine body 1, a processing table 2 is provided on the top of the grinding machine body 1, a sliding frame 3 is slidably connected to the outer wall of the processing table 2, a sliding rod 5 is slidably connected to the outer wall of the sliding frame 3, a processing frame 6 is fixedly connected to the outer wall of the sliding frame 3, a grinding wheel 7 is rotatably connected to the inner side wall of the processing frame 6, and a connecting shaft 8 is fixedly connected to the rotation center of the grinding wheel 7.

[0042] A first locking block 9 is fixedly connected to the end of the connecting shaft 8. A second locking block 10 is engaged with the outer wall of the first locking block 9. A generator shaft 11 is fixedly connected to the outer wall of the second locking block 10. A generator body 14 is provided at one end of the generator shaft 11. A connecting line 15 is provided on the outer wall of the generator body 14. A storage battery 16 is fixedly connected to one end of the connecting line 15 on the outer wall of the sliding rod 5.

[0043] A recovery pipe 17 is fixedly connected to the outer wall of the processing frame 6. A dust collection box 18 is fixedly connected to the outer wall of the recovery pipe 17. A diversion pipe 19 is fixedly connected to the outer wall of the recovery pipe 17. An upper preheating box 20 is fixedly connected to one end of the diversion pipe 19, and a lower preheating box 21 is fixedly connected to the other end of the diversion pipe 19. A grid plate 24 is fixedly connected to the side wall of the processing table 2. The product body 25 is placed on the surface of the grid plate 24. In view of the characteristics of the grinding wheel on the grinding machine grinding the product for a long time, the mechanical energy of the grinding wheel under long-term rotation is converted and recovered, which improves the multi-functionality of the grinding wheel when rotating and reduces the energy consumption rate of the external cylindrical grinding machine during use. According to the heat characteristics generated during grinding, the heat generated is filtered and recovered. 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 would reduce the quality of product grinding.

[0044] like Figure 6 As shown, the outer wall of the sliding frame 3 is fixedly connected to a first electric push rod 4, which is fixedly connected to the outer wall of the sliding rod 5. The outer wall of the generator shaft 11 is provided with a second electric push rod 12. One end of the second electric push rod 12 is fixedly connected to a protective sleeve 13, which is slidably connected to the outer wall of the generator shaft 11.

[0045] like Figure 6 As shown, the inner wall contour of the protective sleeve 13 is adapted to the outer wall contour of the connecting shaft 8 and the generator shaft 11. The first locking block 9 and the second locking block 10 are staggered to each other, which is conducive to achieving the effect of rotational stability of the connecting shaft 8 and the generator shaft 11 through the adaptation of the inner wall contour of the protective sleeve 13 to the outer wall contour of the connecting shaft 8 and the generator shaft 11.

[0046] like Figure 4As shown, an electric fan 22 is installed inside the upper preheating box 20, and a flow grid plate 23 located above the product body 25 is fixedly connected to the bottom of the upper preheating box 20.

[0047] The main body 25 is located in the middle of the upper preheating box 20 and the lower preheating box 21. An electric suction fan is installed inside the recovery pipe 17, and an electrostatic dust removal component is installed inside the dust removal box 18. The outer wall of the grinding machine body 1 is slidably connected to the loading and unloading robotic arm 26. The placement of the main body 25 in the middle of the upper preheating box 20 and the lower preheating box 21 facilitates the preheating effect on the surface of the product to be ground.

[0048] like Figure 4 As shown, the energy storage battery 16 provides power to the electric blower 22 and the electric suction fan installed inside the recovery pipe 17. This is beneficial for converting and recovering the mechanical energy generated by the grinding wheel, thereby reducing the energy loss of the grinding machine during long-term use.

[0049] like Figure 8 As shown, the electrostatic dust removal assembly includes a negative electrode roller 27 and a positive electrode plate 28. The negative electrode roller 27 is installed inside the dust removal box 18, and the positive electrode plate 28 is installed on one side of the negative electrode roller 27. An activated carbon adsorption mesh 29 is installed inside the dust removal box 18 on one side of the positive electrode plate 28. The arrangement of the electrostatic dust removal assembly and the activated carbon adsorption mesh 29 is conducive to removing impurities carried in the recovered heat. When recovering the heat generated by the grinding wheel, the electrostatic dust removal assembly in the dust removal box 18 removes dust and debris from the heat, thereby improving the surface cleanliness of the preheated product and preventing pits from appearing during the grinding process.

[0050] like Figures 9-13 As shown, a servo motor 30 is provided on the outer wall of the processing frame 6. A connecting gear 31 is fixedly connected to the output end of the servo motor 30. A connecting toothed plate 32 meshes with the outer wall of the connecting gear 31. A connecting rod 33 that is slidably connected to the outer wall of the processing frame 6 is fixedly connected to the outer wall of the connecting toothed plate 32. A cleaning scraper 34 is fixedly connected to one end of the connecting rod 33. This facilitates the easy scraping and cleaning of impurities on the surface of the abrasive wheel 7 by setting the cleaning scraper 34.

[0051] like Figure 10As shown, the cleaning scraper 34 has an internal air storage chamber 35 and an external flow port 36. An air supply pipe 37 is located at the top of the cleaning scraper 34, with a connecting pipe 39 fixedly connected to one end. A wind box 38 is fixedly connected to the outer wall of the connecting pipe 39. An electric cooling fan 40 is installed inside the wind box 38. This arrangement, along with the air supply pipe 37, facilitates the simultaneous blowing and cooling of impurities on the surface of the abrasive wheel 7. The dust adsorbed on the surface of the abrasive wheel during product grinding is removed through a scraping and dust-removing motion, and simultaneously cooled by blowing. The servo motor 30, driven by the rotating connecting gear 31, drives the connecting gear... The connecting rod 33, which is fixedly connected to the toothed plate 32, slides along the outer wall of the processing frame 6, so that the cleaning scraper 34 comes into contact with the surface of the grinding wheel 7. Under the rotation of the connecting gear 31, the rotation of the rotating shaft 41 drives the sealing plate 42 to rotate, 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 delivered to the air storage chamber 35 through the delivery pipe 37 and blown onto the surface of the grinding wheel 7 through the flow port 36. This achieves the effect of simultaneously blowing away impurities on the surface of the grinding wheel 7 and simultaneously cooling the grinding wheel 7, which prevents the surface of the grinding wheel from getting too hot and reducing the grinding quality of the product.

[0052] like Figure 11 As shown, a rotating shaft 41 is fixedly connected to the rotation center of the connecting gear 31, and a sealing plate 42 is fixedly connected to one end of the rotating shaft 41 and rotates to be connected to the inner wall of the connecting pipe 39. This facilitates the simultaneous opening of the air supply path when the cleaning scraper 34 cleans the abrasive disc 7.

[0053] like Figure 11 As shown, the energy storage battery 16 provides power to the electric cooling fan 40. The flow port 36 is in contact with the surface of the grinding wheel 7, which is conducive to providing power to the electric cooling fan 40 through the energy storage battery 16, thereby reducing the energy consumption of the grinding machine and improving the efficiency of the grinding machine in grinding products.

[0054] Working principle:

[0055] like Figure 1-13 As shown, when this cylindrical grinding machine is in use, firstly, considering the characteristics of the grinding wheel on the grinding machine grinding the product for a long time, the mechanical energy of the grinding wheel under long-term rotation is converted and recovered, improving the multi-functionality of the grinding wheel when rotating and reducing the energy consumption rate of the cylindrical grinding machine during use. Secondly, based on the heat characteristics generated during grinding, the generated heat is filtered and recovered. Thirdly, the upper and lower sides of the product to be processed are preheated to prevent temperature differences between the product surface and the grinding wheel surface, which would reduce the quality of product grinding.

[0056] Next, when recovering and using the heat generated by the grinding wheel, the electrostatic dust removal component in the dust removal box 18 is used to remove dust and debris from the heat, thereby improving the surface cleanliness of the preheated product and preventing pits from appearing on the product during grinding.

[0057] Finally, the dust adsorbed on the surface of the product during the grinding process is scraped off and simultaneously cooled by blowing. Driven by the servo motor 30, the connecting rod 33, which is fixedly connected to the connecting toothed plate 32, slides along the outer wall of the processing frame 6 through the rotation of the connecting gear 31. This causes the cleaning scraper 34 to come into close contact with the surface of the grinding wheel 7. Under the rotation of the connecting gear 31, the rotating shaft 41 drives the sealing plate 42 to rotate, opening the connecting pipe 39. At the same time, driven by the electric cooling fan 40 driven by the energy storage battery 16, cold air is delivered to the air storage chamber 35 through the delivery pipe 37 and blown onto the surface of the grinding wheel 7 through the flow port 36. This achieves the effect of simultaneously blowing away impurities on the surface of the grinding wheel 7 and simultaneously cooling the grinding wheel 7, preventing the surface of the grinding wheel from getting too hot and reducing the grinding quality of the product.

[0058] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
