Description

Technical Field

[0001] This utility model relates to the technical field of gear shaft processing, specifically a gear shaft grinding device. Background Technology

[0002] The gear shaft of a gear reducer is a crucial component, primarily used for transmitting power and torque. It is a key part of the reducer, and its quality and performance directly affect the overall operating condition and service life of the reducer. A gear shaft typically consists of a journal, gear, and bearings. The journal is the main load-bearing part of the gear shaft, usually needing to withstand significant torque, thus requiring high strength and rigidity. Currently, after the initial machining of the gear shaft, it undergoes further grinding.

[0003] The technical features of the grinding device for gear shaft processing disclosed in Chinese Patent Announcement No. CN218362223U are as follows: It includes a grinding table with grooves on the upper inner sides of both the front and rear ends. Two servo motors are fixedly embedded on one upper side of the grinding table. The output ends of the two servo motors pass through the grinding table and are fixedly connected to threaded rods inside the grinding table. Each of the two threaded rods has a movable rod threadedly fitted onto its shaft. A first fixing plate is fixedly connected to the upper surface of the grinding table near the servo motors, and a second fixing plate is fixedly connected to the middle of the upper surface of the movable rods.

[0004] In the above solution, the fixed sleeves are moved by a servo motor, a threaded rod, and a moving rod to fix the two fixed sleeves to both ends of the gear shaft. This results in the following disadvantage: when the grinding device is in use, the fixing method is singular, and it can only fix the two ends of the gear shaft. Utility Model Content

[0005] The purpose of this invention is to provide a gear shaft grinding device to solve the problem that the current grinding device has a single fixing method and can only fix the two ends of the gear shaft.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a gear shaft grinding device, including a support plate, the support plate being fixed to the top surface of a grinding table, a T-shaped plate being movably arranged inside the grinding table, a fixing plate being fixed to the top surface of the T-shaped plate, two first threaded holes being opened on the front side of the T-shaped plate, two second motors being fixed to the front side of the grinding table, the output shafts of the two second motors respectively passing through the grinding table and respectively fixed with lead screws, the threaded ends of the two lead screws respectively being threadedly connected to the interior of the two first threaded holes, a fixing cylinder being rotatably arranged on the inner side of the support plate and the fixing plate, the outer walls of the two fixing cylinders having second threaded holes on all four sides, bolts being threadedly connected to several second threaded holes, an arc-shaped clamping plate being movably arranged inside the two fixing cylinders, a rotating groove being opened on the outer side of several arc-shaped clamping plates, a rotating block being fixed to the threaded end of several bolts, and several rotating blocks being rotatably arranged in several rotating grooves.

[0007] Preferably, rubber pads are fixed to the inner sides of several of the arc-shaped clamping plates, and anti-slip textures are provided on the inner sides of several of the rubber pads.

[0008] Preferably, the inner wall of the grinding table is provided with sliding grooves on the left and right sides, and the left and right sides of the T-shaped plate are respectively fixed with sliding blocks, and the two sliding blocks are slidably arranged in the two sliding grooves.

[0009] Preferably, a first motor is fixed to the outer side of both the support plate and the fixed plate. The output shafts of the two first motors pass through the support plate and the fixed plate respectively, and are fixedly connected to the outer side of the two fixed cylinders respectively. A mounting base is movably provided above the grinding table. A controller is fixed to the front side of the grinding table. A first cylinder is fixed inside the mounting base. An L-shaped plate is fixed to one end of the telescopic rod of the first cylinder. A third motor is fixed to the rear side of the outer wall of the L-shaped plate. The output shaft of the third motor passes through the L-shaped plate and is fixed with a grinding wheel.

[0010] Preferably, the top surface of the grinding table is provided with a fixing groove, a guide rail is fixed inside the fixing groove, a connecting box is fixed on the top surface of the slider of the guide rail, a second cylinder is fixed inside the connecting box, and one end of the telescopic rod of the second cylinder is fixedly connected to the bottom surface of the mounting base.

[0011] Preferably, the top surface of the connecting box has two limiting grooves, and limiting posts are slidably inserted into the two limiting grooves respectively. The top ends of the two limiting posts are fixedly connected to the bottom surface of the mounting base.

[0012] Compared with the prior art, the gear shaft grinding device adopting the above technical solution has the following beneficial effects:

[0013] 1. In use, the combined use of the support plate, grinding table, T-shaped plate, fixed plate, second motor, lead screw, fixed cylinder, second threaded hole, bolt, arc-shaped clamping plate, rotating groove and rotating block facilitates the fixation of both ends and the outer wall of the gear shaft at multiple points. This not only improves the stability of the gear shaft during the grinding process and effectively reduces grinding errors caused by vibration or shaking, but also adapts to gear shafts of different lengths and diameters, improving the flexibility and practicality of the device.

[0014] Second, during use, the rubber pad protects the gear shaft during clamping, preventing wear on its surface. The anti-slip texture on the rubber pad increases friction, improving stability and ensuring the gear shaft doesn't shift due to rotation or vibration during grinding, thus guaranteeing grinding precision and quality. It also limits the movement of the T-shaped plate, preventing it from shifting or wobbling during movement, improving its stability.

[0015] Third, during use, the device allows for flexible adjustment of the grinding wheel in both left-right and height directions, improving its flexibility and practicality. It also allows for limiting the mounting base, ensuring it does not shift or wobble during lifting and lowering, thus contributing to the overall accuracy of the device during operation.

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-3 As shown, a gear shaft grinding device includes a support plate 1, which is fixed to the top surface of a grinding table 2. A T-shaped plate 3 is movably arranged inside the grinding table 2, and a fixing plate 4 is fixed to the top surface of the T-shaped plate 3. Two first threaded holes 6 are opened on the front side of the T-shaped plate 3. Two second motors 7 are fixed to the front side of the grinding table 2. The output shafts of the two second motors 7 pass through the grinding table 2 and are respectively fixed with lead screws 8. The threaded ends of the two lead screws 8 are respectively threadedly connected to the inside of the two first threaded holes 6. Fixing cylinders 9 are rotatably arranged on the inner sides of the support plate 1 and the fixing plate 4. Second threaded holes 10 are opened on all four sides of the outer wall of the two fixing cylinders 9. Bolts 11 are threadedly connected to the second threaded holes 10. Arc-shaped clamping plates 12 are movably arranged inside the two fixing cylinders 9. Rotating grooves 13 are opened on the outer sides of the arc-shaped clamping plates 12. Rotating blocks 14 are fixed to the threaded ends of the bolts 11. The rotating blocks 14 are rotatably arranged in the rotating grooves 13.

[0023] In use, the operator first places the gear shaft to be ground between two fixed cylinders 9. Then, the second motor 7 is started to rotate the lead screw 8, causing the T-shaped plate 3 to move forward, which in turn moves the rear fixed plate 4 and the rear fixed cylinder 9 forward. This causes the inner walls of the two fixed cylinders 9 to gradually approach the two ends of the gear shaft until they are tightly pressed together, completing the initial fixation of the gear shaft. Then, the operator rotates several bolts 11 one by one, causing the rotating block 14 to rotate inside the rotating groove 13, pushing the arc-shaped clamping plate 12 to move towards the outer wall of the gear shaft. Multiple arc-shaped clamping plates 12 cooperate with each other to clamp and fix the outer wall of the gear shaft from different directions, further enhancing the fixing effect of the gear shaft. The coordinated use of support plate 1, grinding table 2, T-shaped plate 3, fixing plate 4, second motor 7, lead screw 8, fixing cylinder 9, second threaded hole 10, bolt 11, arc-shaped clamping plate 12, rotating groove 13 and rotating block 14 facilitates multi-point fixation of both ends and outer wall of the gear shaft. This not only improves the stability of the gear shaft during the grinding process and effectively reduces grinding errors caused by vibration or shaking, but also adapts to gear shafts of different lengths and diameters, improving the flexibility and practicality of the device.

[0024] like Figures 1-3 As shown, rubber pads 15 are fixed to the inner sides of several arc-shaped clamping plates 12, and anti-slip textures 16 are provided on the inner sides of several rubber pads 15.

[0025] During use, when the operator rotates the bolt 11 and pushes the arc-shaped clamping plate 12 to clamp and fix the gear shaft, the rubber pad 15 will make close contact with the outer wall of the gear shaft, which can protect the gear shaft during the clamping process and avoid wear on the surface of the gear shaft. At the same time, the anti-slip texture 16 on the surface of the rubber pad 15 can increase the friction between the two and improve stability, ensuring that the gear shaft will not be displaced due to rotation or vibration during the grinding process, thereby ensuring the precision and quality of grinding.

[0026] like Figures 1-4 As shown, the inner wall of the grinding table 2 has sliding grooves 17 on the left and right sides respectively. The left and right sides of the T-shaped plate 3 are fixed with sliding blocks 18 respectively. The two sliding blocks 18 are slidably set in the two sliding grooves 17 respectively. The outer sides of the support plate 1 and the fixed plate 4 are both fixed with first motors 5. The output shafts of the two first motors 5 pass through the support plate 1 and the fixed plate 4 respectively, and are fixedly connected to the outer sides of the two fixed cylinders 9 respectively. The mounting base 19 is movably set on the top of the grinding table 2. The front side of the grinding table 2 is fixed with a controller. The controller model is Siemens S7-200. The controller is electrically connected to the second motor 7. The first cylinder 20 is fixed inside the mounting base 19. One end of the telescopic rod of the first cylinder 20 is fixed with an L-shaped plate 29. The rear side of the outer wall of the L-shaped plate 29 is fixed with a third motor 21. The output shaft of the third motor 21 passes through the L-shaped plate 29 and is fixed with a grinding wheel 22.

[0027] In use, when the operator controls the two second motors 7 to rotate synchronously via the controller, the two lead screws 8 rotate synchronously, moving the T-shaped plate 3 back and forth. This causes the sliding block 18 to slide within the slide groove 17, thus limiting the movement of the T-shaped plate 3 and ensuring that it does not deviate or wobble during movement, improving the stability of the T-shaped plate 3 during movement. The operator starts the third motor 21 to rotate the grinding wheel 22, starts the first motor 5 to rotate the fixed cylinder 9, which in turn drives the gear shaft to rotate. Then, the operator starts the first cylinder 20 to move the L-shaped plate 29 and the grinding wheel 22 forward, enabling the grinding of the gear shaft.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, the top surface of the grinding table 2 is provided with a fixing groove 23, and a guide rail 24 is fixed inside the fixing groove 23. A connecting box 25 is fixed on the top surface of the slider of the guide rail 24. A second cylinder 26 is fixed inside the connecting box 25. One end of the telescopic rod of the second cylinder 26 is fixedly connected to the bottom surface of the mounting base 19. Two limiting grooves 27 are provided on the top surface of the connecting box 25. Limiting posts 28 are slidably inserted into the two limiting grooves 27 respectively. The top ends of the two limiting posts 28 are fixedly connected to the bottom surface of the mounting base 19 respectively.

[0029] During use, the operator activates the guide rail 24, allowing the slider on it to move left and right, thereby adjusting the connecting box 25, mounting base 19, and grinding wheel 22. Simultaneously, the operator activates the second cylinder 26 to adjust the height of the mounting base 19 and grinding wheel 22, achieving flexible adjustment of the grinding wheel 22 in both left-right and height directions, improving the flexibility and practicality of the device. When the mounting base 19 is raised or lowered by the second cylinder 26, the limiting post 28 slides into the limiting groove 27, thus limiting the mounting base 19 and ensuring that it does not deviate or wobble during raising or lowering, helping to guarantee the accuracy of the entire device during operation.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
