[0002] A gear refers to a mechanical element with teeth on the rim that can continuously mesh to transmit motion and power. During the processing and manufacturing of gears, in order to improve the quality and precision of gears, after the gears are initially produced, the surfaces of the gears need to be ground to improve the quality of the gears.

[0003] According to the patent application number CN202320027294.1, this utility model belongs to the field of gear processing equipment, and specifically relates to a grinding equipment for gear inner holes, including a grinding disc and a power device arranged on a workbench; a clamping mechanism is arranged on the top of the grinding disc; a lifting mechanism is arranged on the workbench, and its driving end is connected with a support plate; the grinding mechanism includes a first motor, a rotating rod, a mounting block, a motor gear, a rack and a grinding strip. The motor gear and the rack are respectively rotatably and slidably arranged on the mounting block, the motor gear meshes with the rack, one end of the rack is connected with the grinding strip, and the grinding end of the grinding strip can abut against the inner hole wall of the gear to be ground. One end of the mounting block is connected with the bottom of the support plate through a connecting rod, the first motor is installed on the top of the support plate, the driving end of the first motor penetrates through the top of the support plate and is connected with the rotating rod, the lower end of the rotating rod is sleeved in the motor gear, the grinding strip is located directly above the inner hole of the gear to be ground, and the rack can drive the grinding strip to move radially along the inner hole of the gear to be ground to grind gears with different hole diameters.

[0004] Although this equipment can achieve the grinding of the inner holes of gears with multiple sizes, during the grinding process of the gears, a large amount of debris and heat will be generated on the inner wall of the gears. If not cooled in time, it will affect the quality of gear processing and the service life of the products. Currently, some equipment uses water for cooling and chip removal, and in order to facilitate the recycling of water resources, a filter layer is used to isolate and block the debris. However, the accumulated debris will affect the efficiency and quality of water filtration, and thus affect the recycling of water. Summary of the Invention

[0005] The purpose of the present invention is to provide a gear inner hole grinding equipment that can prevent debris accumulation to solve the problems raised in the above background technique.

[0006] To solve the above technical problems, the present invention provides the following technical solution: a gear inner hole grinding device that can prevent debris accumulation, including a base, a support plate symmetrically and fixedly connected to the top of the base, a top plate provided on the top of the base, and the top plate is fixedly connected to the base through the support plate. A workbench is rotatably connected to the top of the base. A first through groove is opened in the center of the workbench. A first recovery groove is opened inside the base. A mounting plate is fixedly connected to the inner wall of the first recovery groove. One end of the mounting plate is fixedly connected to a filter plate. A second recovery groove communicating with the first recovery groove is opened inside the base. The other end of the filter plate is fixedly connected to the base. A first motor is fixedly installed on the inner wall of the base. The output end of the first motor is fixedly connected to a rotating shaft. An impeller is fixedly connected to the outer wall of the rotating shaft. A water tank is fixedly connected to the top of the top plate. A second through groove is opened in the center of the top plate. A lead screw nut moving block is slidably connected inside the second through groove. A first cylinder is fixedly installed at the bottom of the lead screw nut moving block. The output end of the first cylinder is fixedly connected to a mounting block. A second motor is fixedly installed at the bottom of the mounting block.

[0007] Further, a water outlet pipe is fixedly connected to the outer wall of the water tank. A solenoid valve adapted to the water outlet pipe is fixedly installed on the outer wall of the water outlet pipe. The middle section of the water outlet pipe is composed of a flexible hose. The other end of the water outlet pipe is fixedly connected to the mounting block. A groove communicating with the water outlet pipe is opened inside the mounting block. By setting the middle section of the water outlet pipe as a flexible hose, it is convenient for the subsequent height and length self-adjustment of the water outlet pipe.

[0008] Further, a guiding block is fixedly connected to the bottom of the mounting block. The guiding block is annular in shape. A plurality of guiding grooves communicating with the groove are circumferentially and equidistantly opened inside the guiding block. The output end of the second motor is fixedly connected to a grinding disc. Through the guiding grooves, water can be accurately sprayed around the grinding disc, thereby facilitating the cooling of the grinding disc and also facilitating chip removal.

[0009] Further, a protective shell adapted to the impeller is fixedly connected to the inner wall of the base. The protective shell is sleeved outside the impeller. One end of the protective shell is fixedly connected to a recovery pipe. The bottom of the protective shell is fixedly connected to a guiding pipe. The other end of the guiding pipe is fixedly connected to the water tank. Through the guiding pipe, it is convenient to recycle and reuse the used water.

[0010] Furthermore, one end of the rotating shaft extends to the outside of the protective shell, and the other end of the rotating shaft is fixedly connected to the first bevel gear, and the inner wall of the base is fixedly connected to a fixing rod, the top of the fixing rod is rotatably connected to a second bevel gear meshing with the first bevel gear, the top of the second bevel gear is hinged with a connecting rod, and the other end of the connecting rod is hinged with a moving rod, the moving rod is slidably connected to the mounting plate, and the bottom of the moving rod is fixedly connected to a cleaning brush adapted to the filter plate, and through the cooperation of the first bevel gear and the second bevel gear, the moving rod can drive the cleaning brush to move while the impeller is working, so that the cleaning brush can clean the debris on the top of the filter plate, and the larger transmission ratio between the first bevel gear and the second bevel gear can prevent the moving rod from moving too fast.

[0011] Furthermore, a matching recovery box is slidably connected inside the second recovery groove, and the other end of the recovery box extends to the outside of the base, so that the debris can be conveniently collected and processed in a centralized manner through the recovery box.

[0012] Furthermore, a third motor is fixedly installed on the outer wall of the top plate, and a ball screw is fixedly connected to the output end of the third motor. The screw nut moving block is sleeved on the outside of the ball screw, and the screw nut moving block is transmission-connected to the top plate through the ball screw. By using the ball screw in conjunction with the screw nut moving block, it is convenient for the user to adjust the position of the grinding disc, thereby facilitating the user to perform grinding operations on inner holes of multiple sizes.

[0013] Furthermore, the outer wall of the screw nut moving block is symmetrically fixed with two sliders, and the inside of the top plate is symmetrically provided with two sliding grooves adapted to the sliders. The screw nut moving block is slidably connected to the sliding grooves through the sliders. Through the coordinated use of the sliders and the sliding grooves, the screw nut moving block can have stability when moving.

[0014] Furthermore, the workbench is circular in shape, and two second cylinders are symmetrically fixedly installed on the top of the workbench. The output ends of the two second cylinders are fixedly connected with clamps, and the gears can be easily fixed by the second cylinders and the clamps, thereby ensuring the stability of the gears during processing.

[0015] Furthermore, a gear ring is fixedly connected to the outer wall of the workbench, a fourth motor is fixedly installed on the top of the base, and a first gear meshing with the gear ring is fixedly connected to the output end of the fourth motor. Through the cooperation of the first gear and the gear ring, the gear can rotate when being polished by the polishing disc, thereby facilitating the annular polishing operation on the inner wall of the gear.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0017] 1. Through the combined use of the moving rod and the cleaning brush, when the water containing debris passes through the filter plate, the debris is filtered and blocked by the filter plate. Subsequently, the water without debris can fall to the bottom of the filter plate. At this time, the swinging of the connecting rod can drive the moving rod and the cleaning brush to clean the debris on the surface of the filter plate. Through the cleaning of the cleaning brush and the impact of the water at the top, the debris can enter the inside of the recycling box through the filter plate, which facilitates the centralized collection of debris by the device and enables the recycling of water at the same time.

[0018] 2. Through the combined use of the first gear and the toothed ring, when the user needs to grind and process the inner holes of gears of different sizes, the user can first place the gear on the top of the workbench for fixation. Subsequently, adjust the height of the grinding disc so that the grinding disc moves into the inner hole of the gear. Then the user adjusts the third motor to drive the ball screw to rotate, so that the screw nut moving block can drive the first cylinder, the mounting block and the grinding disc to move, so that the outer wall of the grinding disc can contact the inner hole of the gear. Subsequently, the user turns on the fourth motor to drive the first gear to rotate. At this time, the first gear can make the workbench rotate by squeezing the toothed ring, so that the gear can rotate, which facilitates the grinding and processing of the inner holes of gears of multiple sizes by the device.

The workbench 4 is circular in shape. Two second cylinders 38 are symmetrically and fixedly installed at the top of the workbench 4. The output ends of the two second cylinders 38 are fixedly connected with clamping plates 39. The outer wall of the workbench 4 is fixedly connected with a toothed ring 40. A fourth motor 41 is fixedly installed at the top of the base 1. The output end of the fourth motor 41 is fixedly connected with a first gear 42 that meshes with the toothed ring 40.,

[0030] The implementation method is as follows: When the user needs to grind the inner hole of the gear, first place the gear on the top of the workbench 4. Then the user turns on two second cylinders 38 to drive the clamping plates 39, so that the clamping plates 39 can clamp the gear, and at the same time, the gear is displaced to the central position and fixed. Then the user can adjust the position of the grinding disc 23 according to the size of the inner hole of the gear. First, adjust the first cylinder 16 to drive the mounting block 17, the guiding block 21, the second motor 18 and the grinding disc 23 to move downward, so that the grinding disc 23 moves to the inner hole of the gear. Then the user can drive the ball screw 35 to rotate by adjusting the third motor 34, so that the screw nut moving block 15 can adjust its position. At this time, the screw nut moving block 15 adjusts its position along the sliding groove 37 through the slider 36. When the outer wall of the grinding disc 23 contacts the inner hole of the gear, the user turns off the third motor 34 at this time. Then the user turns on the fourth motor 41 and the second motor 18. At this time, the second motor 18 drives the grinding disc 23 to grind the inner hole of the gear. At the same time, the first gear 42 drives the toothed ring 40 and the workbench 4 to rotate, so that the gear can rotate when the inner hole is being ground, thereby realizing the circular grinding of the inner hole of the gear, and enabling the equipment to grind the inner holes of gears of multiple sizes. And during the gear grinding process, in order to prevent debris from scattering and accumulating, the user can turn on the solenoid valve outside the water outlet pipe 19 at this time, so that the water in the water tank 13 enters the tank body 20 through the water outlet pipe 19. Then the water is sprayed out through a plurality of guiding grooves 22, which can realize the cooling of the grinding disc 23 and the gear, and at the same time can handle the debris generated by grinding, thereby preventing the debris from accumulating in the inner hole of the gear. At the same time, the debris will enter the inside of the first recovery tank 6 through the first through groove 5 together with the water. At this time, the debris in the water is blocked by the filter plate 8. In order to make the water resource recyclable, the user can turn on the first motor 10 to work at this time. Then the rotating shaft 11 can drive the impeller 12 to rotate. At this time, the water in the first recovery tank 6 can enter the guiding pipe 26 through the recovery pipe 25 under the rotation of the impeller 12, and finally the water can enter the inside of the water tank 13, thereby completing the recycling of the water resource. At the same time, the equipment can realize the centralized treatment of the debris, and can prevent the water filtration efficiency of the filter plate 8 from decreasing due to the accumulation of debris. When the debris accumulates on the flat part of the filter plate 8, at this time, the rotation of the rotating shaft 11 can drive the first bevel gear 27, and then the first bevel gear 27 drives the second bevel gear 29 to rotate. At this time, the second bevel gear 29 rotates smoothly along the fixed rod 28. During the rotation of the fixed rod 28, it can drive the connecting rod 30 and the moving rod 31 to move. When the moving rod 31 moves to the right, at this time, the moving rod 31 can drive the cleaning brush 32 to remove the impurities on the flat part of the filter plate 8, thereby ensuring the water filtration efficiency and quality of the filter plate 8.Meanwhile, it enables the debris to move centrally to the inclined surface portion of the filter plate 8, and finally enables the debris to enter the inside of the recycling box 33 under the impact of water, thereby facilitating the user to centrally collect the debris. When the moving rod 31 moves to the bottom of the first through groove 5, the top of the moving rod 31 can block the debris at this time, thereby preventing the debris from moving to the left side of the cleaning brush 32, ensuring the efficiency and quality of debris collection, reducing the burden on the user to collect debris, and realizing the recycling of water resources at the same time.

[0031] The working principle of the present invention:

[0032] Refer to Figure 1 - Figure 7 Through the coordinated use of the moving rod 31 and the cleaning brush 32, when the water containing debris passes through the filter plate 8, the debris is filtered and blocked by the filter plate 8 at this time. Subsequently, the water without debris can fall to the bottom of the filter plate 8. At this time, the connecting rod 30 swings to drive the moving rod 31 and the cleaning brush 32 to clean the debris on the surface of the filter plate 8. Through the cleaning of the cleaning brush 32 and the impact of the water at the top, the debris can enter the inside of the recycling box 33 through the filter plate 8, facilitating the equipment to centrally collect the debris and recycling the water at the same time.

[0033] Furthermore, through the coordinated use of the first gear 42 and the tooth ring 40, when the user needs to grind and process the inner holes of gears of different sizes, the user can first place the gear on the top of the workbench 4 for fixation, and then adjust the height of the grinding disc 23 so that the grinding disc 23 moves into the inner hole of the gear. Then the user adjusts the third motor 34 to drive the ball screw 35 to rotate, so that the screw nut moving block 15 can drive the first cylinder 16, the mounting block 17 and the grinding disc 23 to move, so that the outer wall of the grinding disc 23 can contact the inner hole of the gear. Subsequently, the user turns on the fourth motor 41 to drive the first gear 42 to rotate. At this time, the first gear 42 can make the workbench 4 rotate by pressing the tooth ring 40, so that the gear rotates, facilitating the equipment to grind and process the inner holes of gears of multiple sizes.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
