Abstract
Description
Technical Field
[0001] This utility model relates to the field of gear shaft grinding technology, and in particular to a grinding device for gear shaft processing. Background Technology
[0002] A gear shaft is a mechanical part that supports rotating parts and rotates with them to transmit motion, torque, or bending moment. It is generally a round metal rod, with different diameters for each section. Rotating parts in a machine are mounted on shafts. Based on the shape of the shaft axis, shafts can be divided into crankshafts and straight shafts. Based on the load-bearing capacity, shafts can also be divided into: ① Rotating shafts, which bear both bending moment and torque during operation; these are the most common shafts in machinery, such as the shafts in various reducers. ② Spindles, which support rotating parts and only bear bending moment without transmitting torque. Some spindles rotate, such as the axles of railway vehicles, while others do not rotate, such as the shafts supporting pulleys. ③ Drive shafts, which are mainly used to transmit torque without bearing bending moment, such as the long shafts in the moving mechanisms of cranes and the drive shafts of automobiles.
[0003] During the gear shaft machining process, a grinding device is needed to grind the gear shaft to correct the errors generated during the previous cutting process and improve the accuracy of the gear shaft. Generally, the grinding disc is driven by a motor to rotate, and the grinding disc is moved by a moving mechanism so that the grinding disc comes into contact with the gear shaft, thereby grinding the gear shaft.
[0004] However, gear shafts have different parts such as end faces, conical surfaces, or tooth root transition fillets. Moreover, the grinding components of traditional grinding devices have fixed angles and can usually only process outer diameters or surfaces with specific angles. When grinding the end faces, conical surfaces, or tooth root transition fillets of gear shafts, the gear shafts need to be placed inside different grinding devices. This means that the gear shafts need to be fixed in different grinding devices. However, each clamping of the gear shaft will cause errors due to the deviation of the positioning reference, which can easily affect the coaxiality, perpendicularity, and other critical accuracy of the gear shafts. Based on the above problems, this application proposes a grinding device for gear shaft processing. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example: Refer to Figure 1-4A grinding device for gear shaft machining includes a mounting base 1. Two linear motors 2 are fixedly mounted on the top of the mounting base 1, arranged symmetrically. The two linear motors 2 are of identical specifications. A mounting bracket 3 is mounted on the surface of each linear motor 2. A lateral movement component is located inside the mounting bracket 3. A mounting housing 9 is mounted on the top of the mounting base 1 via the lateral movement component. An angle adjustment component is located on the surface of the mounting housing 9. A grinding motor 15 is mounted on the top of the mounting housing 9 via the angle adjustment component. A grinding shaft 16 is fixedly mounted at the output end of the grinding motor 15. A grinding disc 17 is fixedly mounted on the surface of the grinding shaft 16. A clamping component is located on the top of the mounting base 1. The angle adjustment component includes an adjustment motor 10 fixedly mounted on the left side of the mounting housing 9. A worm gear 11 is fixedly mounted at the output end of the adjustment motor 10. A worm wheel 12 meshes with the surface of the worm gear 11. Both the worm gear 11 and the worm wheel 12 are located inside the mounting housing 9. Both worm gear 11 and worm wheel 12 are made of stainless steel. A rotating shaft 13 is fixedly installed inside the worm wheel 12. The rotating shaft 13 is rotatably installed inside the mounting housing 9. A fixed bracket 14 is fixedly installed on the top of the rotating shaft 13. The bottom of the fixed bracket 14 overlaps with the top of the mounting housing 9. The grinding motor 15 is fixedly installed on the right side wall of the fixed bracket 14. According to the grinding position of the gear shaft, the motor 10 drives the rotating shaft 13 to rotate through the worm gear 11 and worm wheel 12. The rotating shaft 13 drives the fixed bracket 14 to rotate, so that the grinding motor 15 drives the grinding disc 17 to make a circular motion through the grinding shaft 16, thereby adjusting the angle between the grinding disc 17 and the gear shaft. This allows grinding of different positions of the gear shaft. The angle of the grinding disc 17 can be adjusted according to the grinding requirements of the gear shaft. This eliminates the need to use different grinding devices to grind the gear shaft when grinding different positions, avoiding the reduction in machining accuracy caused by multiple fixings of the gear shaft.
[0022] It is worth mentioning that the aforementioned linear motor 2 mainly consists of a stator, a mover, and an auxiliary structure. The stator and the mover maintain a small air gap and have no mechanical contact. The permanent magnet placed on the mover in the linear motor 2 generates a constant magnetic field, which interacts with the traveling wave magnetic field of the stator to form a driving force along the linear direction. Since the traveling wave magnetic field moves at a constant speed, the mover will follow the magnetic field and move at the same speed. By adjusting the frequency and phase of the stator current, the speed and direction of the traveling wave magnetic field can be precisely controlled, thereby controlling the speed, displacement, and direction of the mover. Therefore, the linear motor 2 can be regarded as prior art and will not be described in detail below.
[0023] Specifically, the lateral movement component includes a servo motor 4 fixedly mounted on the left side of the mounting bracket 3. A coupling is fixedly mounted on the output end of the servo motor 4, and a rotating screw 5 is fixedly mounted on the output end of the servo motor 4 via the coupling. A mounting seat 6 is threaded onto the surface of the rotating screw 5, and a guide rod 7 is slidably mounted inside the mounting seat 6. The guide rod 7 is fixedly mounted inside the mounting bracket 3. A mounting plate 8 is fixedly mounted on the top of the mounting seat 6, and a mounting housing 9 is fixedly mounted on the top of the mounting plate 8. The rotating screw 5 and the guide rod 7 are vertically aligned, with the rotating screw 5 located above the guide rod 7. Both the rotating screw 5 and the guide rod 7 are made of stainless steel. The servo motor 4 drives the coupling to rotate the rotating screw 5, allowing the mounting seat 6 to move. The mounting plate 8 moves through the mounting housing 9 and is guided by the guide rod 7 to the mounting base 6. The rotating shaft 13 drives the grinding motor 15 to move through the fixed bracket 14. The grinding motor 15 drives the grinding disc 17 to move through the grinding shaft 16, so that the grinding disc 17 grinds different positions of the gear shaft. The position of the grinding disc 17 can be adjusted according to the grinding requirements of the gear shaft. In addition, during the use of the rotating screw 5, the rotating screw 5 and the guide rod 7 can be protected by the corrugated protective sleeve. The corrugated protective sleeve is installed between the mounting base 6 and the mounting bracket 3 to shield and protect the rotating screw 5 and the guide rod 7, preventing grinding dust and debris from adhering to the rotating screw 5 and the guide rod 7.
[0024] Specifically, the clamping assembly includes a mounting vertical plate 18 fixedly mounted on the top of the mounting base 1. A connecting bracket 19 is fixedly mounted on the left side of the mounting vertical plate 18. A geared motor 20 is fixedly mounted on the left side of the connecting bracket 19. A coupling is fixedly mounted on the output end of the geared motor 20. A rotating shaft 21 is fixedly mounted on the output end of the geared motor 20 via the coupling. A left fixed head 22 is fixedly mounted on the right end of the rotating shaft 21. A hydraulic push rod 23 is fixedly mounted on the right side of the connecting bracket 19. A rotating sleeve 24 is rotatably mounted on the output end of the hydraulic push rod 23. A right fixed head 25 is fixedly mounted on the left end of the rotating sleeve 24. The part to be ground... The gear shaft is placed between the left fixed head 22 and the right fixed head 25, so that the gear shaft contacts the right end of the left fixed head 22. The output end is driven by the hydraulic push rod 23 to move the rotating sleeve 24, so that the rotating sleeve 24 pushes the right fixed head 25 to contact the gear shaft. The gear shaft is fixed, and the output end is driven by the geared motor 20 to drive the rotating shaft 21 to rotate through the coupling. The rotating shaft 21 drives the left fixed head 22 to rotate. Since the gear shaft is clamped by the left fixed head 22 and the right fixed head 25, the gear shaft drives the right fixed head 25 to rotate through the rotating sleeve 24, thereby changing the grinding surface of the gear shaft.
[0025] In use: Based on the grinding position of the gear shaft, the output end of the adjusting motor 10 drives the worm gear 11 to rotate, which in turn drives the meshing worm wheel 12 to rotate. The worm wheel 12 drives the rotating shaft 13 to rotate inside the mounting housing 9, which in turn drives the fixed bracket 14 to rotate. The fixed bracket 14 then drives the grinding motor 15 to rotate, causing the grinding motor 15 to drive the grinding disc 17 to perform circular motion via the grinding shaft 16. This adjusts the angle between the grinding disc 17 and the gear shaft. After adjustment, the linear motor 2 drives the moving seat to move the mounting bracket 3. The mounting bracket 3 then drives the rotating screw 5 and guide rod 7 to move, causing the rotating screw 5 and guide rod 7 to move the mounting seat 6. The mounting seat 6 then moves the mounting plate 8, which in turn moves the adjusting motor 15 through the mounting housing 9. The movement of the machine 10, worm gear 11, and rotating shaft 13 causes the rotating shaft 13 to move the fixed bracket 14, which in turn causes the grinding motor 15 to move the grinding disc 17 via the grinding shaft 16, bringing the grinding disc 17 into contact with the grinding position of the gear shaft. The grinding motor 15 drives the grinding disc 17 to rotate via the grinding shaft 16, allowing the grinding disc 17 to grind the gear shaft. The servo motor 4 drives the coupling to rotate the rotating screw 5, which in turn drives the mounting base 6 to move. The guide rod 7 guides the mounting base 6, causing the mounting plate 8 to move via the mounting housing 9, which in turn drives the adjusting motor 10, worm gear 11, and rotating shaft 13, and the fixed bracket 14 to move the grinding motor 15. The grinding motor 15 then drives the grinding disc 17 via the grinding shaft 16, allowing the grinding disc 17 to grind different positions on the gear shaft.
