[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1

[0032] Please see Figure 1-4 This invention provides a technical solution: a surface grinding device for gear production, comprising a device housing 1, a support plate 2 fixedly connected to the inner side of the device housing 1, a sleeve 3 fixedly connected to the top of the support plate 2, a plurality of sleeves 3, a first electric push rod 4 symmetrically fixedly connected to the top of the support plate 2, a lower support plate 5 fixedly connected to the output end of the first electric push rod 4, the lower support plate 5 being located outside the sleeve 3, a first sliding rod 6 uniformly slidably connected to the top of the lower support plate 5 on the outer side of the sleeve 3, a first mounting plate 7 fixedly connected to the top of each of the first sliding rods 6, a first spring 8 provided at the bottom of each of the first mounting plates 7 on the outer side of the first sliding rods 6, a lower sanding disc 9 provided at the top of each of the first mounting plates 7, a rotating shaft 10 rotatably connected to the inner side of each of the sleeves 3, and a gear limiting block 11 provided at the top of each of the rotating shafts 10. By setting a plurality of gear limiting blocks 11, multiple gears can be ground simultaneously, facilitating mass production.

[0033] An upper pressure plate 12 is slidably connected to the inner side of the outer casing 1 above the lower support plate 5. A fixing rod 13 is fixedly connected to the bottom end of the upper pressure plate 12 corresponding to the sleeve 3. A fixing plate 14 is fixedly connected to the bottom end of each fixing rod 13. An upper pressure block 16 is rotatably connected to the bottom end of each fixing plate 14 via a connecting shaft 15. A second sliding rod 17 is slidably connected to the top end of the fixing plate 14 outside the fixing rod 13. A baffle 18 is fixedly connected to the top end of the second sliding rod 17 above the fixing plate 14. A second mounting plate 19 is fixedly connected to the bottom end of the second sliding rod 17. A second spring 20 is provided on the outer side of the second sliding rod 17 between the fixing plate 14 and the second mounting plate 19. An upper sanding disc 21 is provided at the bottom end of each second mounting plate 19. By setting the gear limiting block 11 and the upper pressure block 16, the sanding disc 16 is slidably connected to the upper support plate 16. The gear is placed at the top of the gear limiting block 11. As the upper pressure plate 12 moves downward, the upper pressure block 16 contacts the top of the gear, thereby clamping and fixing the gear through the gear limiting block 11 and the upper pressure block 16, achieving the effect of facilitating gear fixation. Furthermore, by setting the first mounting plate 7 and the second mounting plate 19, the lower sanding disc 9 and the upper sanding disc 21 are respectively assembled with the first mounting plate 7 and the second mounting plate 19. The bottom end of the first mounting plate 7 and the top end of the second mounting plate 19 are respectively provided with the first spring 8 and the second spring 20. Under the action of the first spring 8, the first mounting plate 7 provides elastic support to the lower end face of the gear, and under the action of the second spring 20, it provides elastic pressure to the upper end face of the gear, thereby preventing the gear from being damaged by hard pressure during the grinding process.

[0034] The working principle and usage process of this invention are as follows: In use, the gear to be processed is placed on the top of the gear limiting block 11. After the gear is placed, the upper pressure plate 12 pushes the fixing rod 13 at its bottom end and the fixing plate 14 at the bottom end of the fixing rod 13 downwards. The upper pressure block 16 is rotatably connected to the middle position of the bottom end of the fixing plate 14 via the connecting shaft 15. As the upper pressure plate 12 moves downwards, the upper pressure block 16 contacts the top end of the gear, thereby clamping and fixing the gear through the gear limiting block 11 and the upper pressure block 16. Since the second sliding rod 17 is uniformly slidably connected to the outer side of the fixing plate 14, and the bottom end of the second sliding rod 17 is fixedly connected to the second mounting plate 19, and the bottom end of the second mounting plate 19 is equipped with an upper sanding disc 21, as the upper pressure block 16 approaches the gear, the upper sanding disc 21 contacts the upper end face of the gear. Furthermore, with the pushing of the upper pressure plate 12, the upper end face of the gear is elastically pressed under the action of the second spring 20. The first electric push rod 4 pushes the lower support plate 5 upward inside the device housing 1, thereby simultaneously pushing the first sliding rod 6, the first mounting plate 7, and the lower sanding plate 9 at its top upward. During the upward movement, the lower sanding plate 9 contacts the lower end face of the gear. As the first electric push rod 4 pushes, the first spring 8 at the bottom of the first mounting plate 7 provides elastic support to the lower end face of the gear. Then, the rotating shaft 10 drives the gear limiting block 11 threaded at its top to rotate together with the gear. The upper pressure block 16 at the top of the gear rotates with the gear under the action of the connecting shaft 15, and simultaneously presses the gear. During the rotation of the gear, the upper sanding plate 21 and the lower sanding plate 9 located at the upper and lower ends of the gear grind both ends of the gear simultaneously, thereby improving the grinding efficiency of the gear. Furthermore, by setting several gear limiting blocks 11, multiple gears can be ground simultaneously, which is convenient for mass production.

By setting a plurality of gear limiting blocks 11, multiple gears can be ground simultaneously, facilitating mass production.

[0037] An upper pressure plate 12 is slidably connected to the inner side of the outer casing 1 above the lower support plate 5. A fixing rod 13 is fixedly connected to the bottom end of the upper pressure plate 12 corresponding to the sleeve 3. A fixing plate 14 is fixedly connected to the bottom end of each fixing rod 13. An upper pressure block 16 is rotatably connected to the bottom end of each fixing plate 14 via a connecting shaft 15. A second sliding rod 17 is slidably connected to the top end of the fixing plate 14 outside the fixing rod 13. A baffle 18 is fixedly connected to the top end of the second sliding rod 17 above the fixing plate 14. A second mounting plate 19 is fixedly connected to the bottom end of the second sliding rod 17. A second spring 20 is provided on the outer side of the second sliding rod 17 between the fixing plate 14 and the second mounting plate 19. An upper sanding disc 21 is provided at the bottom end of each second mounting plate 19. By setting the gear limiting block 11 and the upper pressure block 16, the sanding disc 16 is slidably connected to the upper support plate 16. The gear is placed at the top of the gear limiting block 11. As the upper pressure plate 12 moves downward, the upper pressure block 16 contacts the top of the gear, thereby clamping and fixing the gear through the gear limiting block 11 and the upper pressure block 16, achieving the effect of facilitating gear fixation. Furthermore, by setting the first mounting plate 7 and the second mounting plate 19, the lower sanding disc 9 and the upper sanding disc 21 are respectively assembled with the first mounting plate 7 and the second mounting plate 19. The bottom end of the first mounting plate 7 and the top end of the second mounting plate 19 are respectively provided with the first spring 8 and the second spring 20. Under the action of the first spring 8, the first mounting plate 7 provides elastic support to the lower end face of the gear, and under the action of the second spring 20, it provides elastic pressure to the upper end face of the gear, thereby preventing the gear from being damaged by hard pressure during the grinding process.

[0038] In this invention, preferably, the lower support plate 5 is slidably connected to the inner side of the device housing 1 via the first slide rail 22. The first slide rail 22 is located on both sides of the lower support plate 5. The top of the lower support plate 5 is provided with a through hole corresponding to the sleeve 3. The sleeve 3 is located inside the through hole to ensure the stable sliding of the lower support plate 5.

[0039] In this invention, preferably, a second electric push rod 23 is fixedly connected to the top of the inner part of the device housing 1. The output end of the second electric push rod 23 is fixedly connected to the top of the upper pressure plate 12. The upper pressure plate 12 is slidably connected to the inner side of the device housing 1 via a second slide rail 24. The second slide rail 24 is located on both sides of the upper pressure plate 12, so that the second electric push rod 23 pushes the upper pressure plate 12 to slide downward along the second slide rail 24 on the inner side of the device housing 1, thereby causing the upper pressure plate 12 to push the fixing rod 13 at its bottom end and the fixing plate 14 at the bottom end of the fixing rod 13 to move downward.

[0040] In this invention, preferably, the bottom end of the rotating shaft 10 is fixedly connected to a driving pulley 25 and a driven pulley 26, respectively. The driving pulley 25 and several driven pulleys 26 are connected by a transmission belt 27. The driving pulley 25 is fixedly connected to the output end of the worm gearbox 28. The other end of the worm gearbox 28 is fixedly connected to the output end of the drive motor 29. The output end of the drive motor 29 is connected to the driving pulley 25 through the worm gearbox 28. The drive motor 29 drives the driving pulley 25 to rotate through the worm gearbox 28. The driving pulley 25 drives the driven pulleys 26 to rotate through the transmission belt 27. Thus, the driving pulley 25 and the driven pulleys 26 simultaneously drive the rotating shaft 10 to rotate inside the sleeve 3, thereby causing the rotating shaft 10 to drive the gear limiting block 11 threaded at its top end to rotate together with the gear.

[0041] In this invention, preferably, the top of the first mounting plate 7 is fixedly connected to the lower sanding plate 9 by fixing bolts 30, and the bottom of the second mounting plate 19 is fixedly connected to the upper sanding plate 21 by fixing bolts 30, which facilitates the replacement of the lower sanding plate 9 and the upper sanding plate 21 and has good adaptability.

[0042] In this invention, preferably, threaded sleeves 31 are fixedly connected to the sides of the gear limiting block 11 and the upper pressure block 16 that are far apart from each other. The gear limiting block 11 and the upper pressure block 16 are respectively threaded to the rotating shaft 10 and the connecting shaft 15 through the threaded sleeves 31, which makes it easy to replace the gear limiting block 11 and the upper pressure block 16 according to the size of the gear to meet more usage needs.

[0043] In this invention, preferably, both the gear limiting block 11 and the upper pressing block 16 are fixedly connected to a boss 32 on the side that is close to each other, and both the gear limiting block 11 and the upper pressing block 16 are provided with anti-slip rubber pads 33 on the outer side of the boss 32 on the side that is close to each other, which can prevent the gear from slipping during rotation and prevent the gear limiting block 11 and the upper pressing block 16 from damaging the end face of the gear.

[0044] In this invention, preferably, a baffle 34 is fixedly connected inside the outer shell 1 of the device to the back of the support plate 2. A rectangular window is opened inside the baffle 34, and the top of the support plate 2 is flush with the bottom of the rectangular window. When cleaning inside the device, the grinding waste is blown to the other side of the baffle 34 through the rectangular window, which facilitates the centralized treatment of the waste.

[0045] In this invention, preferably, the outer side of the device housing 1 is provided with a double door 35, a control switch 37, and a warning light 38. An observation window 36 is provided inside the double door 35. The control switch 37 and the warning light 38 are located below and above the double door 35, respectively. When the double door 35 on the outer side of the device housing 1 is opened, the gear to be processed is placed on the top of the gear limiting block 11. After the gear limiting block 11 and the upper pressure block 16 clamp the gear, the double door 35 on the outer side of the device housing 1 is closed. The drive motor 29 is started by the control switch 37. At this time, the warning light 38 on the outer side of the device housing 1 lights up. After the grinding is completed, the warning light 38 on the outer side of the device housing 1 goes out. The second electric push rod 23 and the first electric push rod 4 automatically return to their original positions. Then the double door 35 is opened to replace the gear, making the use safer.

[0046] In this invention, preferably, the first electric push rod 4, the second electric push rod 23, the drive motor 29, and the warning light 38 are all electrically connected to the control switch 37, so that the first electric push rod 4, the second electric push rod 23, and the drive motor 29 can be controlled by the control switch 37, making it more convenient to use.

[0047] The working principle and usage process of this invention are as follows: In use, open the double door 35 on the outside of the device housing 1, and place the gear to be processed on the top of the gear limiting block 11. The top of the gear limiting block 11 is provided with a boss 32, the outer diameter of which is smaller than the inner diameter of the gear, thus positioning the gear and facilitating its placement. Several gear limiting blocks 11 are provided inside the device housing 1, allowing multiple gears to be placed simultaneously. After the gear is placed, the control switch 37 on the outside of the device housing 1 controls the second electric push rod 23 at the top inside the device housing 1. This causes the second electric push rod 23 to push the upper pressure plate 12 downwards along the second slide rail 24 inside the device housing 1, thereby causing the upper pressure plate 12 to push the fixing rod 13 at its bottom and the fixing rod 13 at its bottom. As plate 14 moves downward, an upper pressure block 16 is rotatably connected to the middle of the bottom end of fixed plate 14 via connecting shaft 15. As upper pressure plate 12 moves downward, upper pressure block 16 contacts the top of gear, thereby clamping and fixing the gear through gear limiting block 11 and upper pressure block 16. A second sliding rod 17 is uniformly slidably connected to the outer side of fixed plate 14, and a second mounting plate 19 is fixedly connected to the bottom end of the second sliding rod 17. An upper sanding disc 21 is mounted on the bottom end of the second mounting disc 19. As the upper pressure block 16 approaches the gear, the upper sanding disc 21 contacts the upper end face of the gear. With the pushing of upper pressure plate 12, the upper end face of the gear is elastically pressed under the action of the second spring 20. Then, the control switch 37 controls the top of the support plate 2... An electric push rod 4 pushes the lower support plate 5 upward along the first slide rail 22 inside the device housing 1. This, in turn, pushes the first slide rod 6, the first mounting plate 7, and the lower sanding disc 9 upward simultaneously. During this upward movement, the lower sanding disc 9 contacts the lower end face of the gear. As the first electric push rod 4 pushes, the first spring 8 at the bottom of the first mounting plate 7 provides elastic support to the lower end face of the gear. Then, the double door 35 on the outside of the device housing 1 is closed, and the drive motor 29 is started via the control switch 37. At this time, the warning light 38 on the outside of the device housing 1 illuminates. The drive motor 29 drives the drive pulley 25 to rotate via the worm gear reducer 28. The drive pulley 25 is connected to the transmission belt 27. The driven pulley 26 rotates, which in turn causes the driving pulley 25 and the driven pulley 26 to simultaneously drive the rotating shaft 10 to rotate inside the sleeve 3. This causes the rotating shaft 10 to drive the gear limiting block 11, which is threaded to its top, to rotate together with the gear. The upper pressure block 16, located at the top of the gear, rotates with the gear under the action of the connecting shaft 15, and simultaneously presses the gear. Both the gear limiting block 11 and the upper pressure block 16 are provided with anti-slip rubber pads 33 on the side near the gear to prevent the gear from slipping during rotation and to prevent the gear limiting block 11 and the upper pressure block 16 from damaging the gear end face. During the rotation of the gear, the upper sanding disc 21 and the lower sanding disc 9, located at the upper and lower ends of the gear respectively, simultaneously grind both ends of the gear, thereby improving the grinding efficiency of the gear.Furthermore, by setting several gear limit blocks 11, multiple gears can be ground simultaneously, facilitating mass production. After grinding is complete, the warning light 38 on the outside of the device housing 1 goes out, the second electric push rod 23 and the first electric push rod 4 automatically return to their origin, and then the double door 35 is opened to replace the gears.
