Description

Technical Field

[0001] This utility model belongs to the field of gear processing technology, and in particular relates to a gear surface polishing device. Background Technology

[0002] A gear is a mechanical component that transmits motion and power through continuous meshing of gears on its rim. Gears have been used in transmission for a long time. In the late 19th century, the principle of generating gear cutting and the emergence of special machine tools and cutting tools for gear cutting based on this principle appeared. With the development of production, the surface of gears is relatively rough after processing. If they are directly installed on heavy vehicles, it will affect the meshing degree between gears and cause errors in gear transmission. Therefore, after the gears are manufactured, they need to be polished to improve the meshing degree between gears.

[0003] In the prior art, Chinese utility model patent with patent number CN219234160U discloses a gear surface polishing device. The key technical points of the device are: a placement table, on the top surface of which a placement frame is fixedly connected, and the top surface of the placement frame has a fixing hole; a placement plate, which is rotatably mounted on the top surface of the placement table, and a positioning rod is threadedly connected to the inside of the placement plate; and a grinding assembly, which is disposed on the top surface of the placement table and is used to grind the gear.

[0004] While the aforementioned prior art facilitates gear polishing, it can only polish one side of the gear and cannot polish both sides simultaneously. Furthermore, the polishing process generates debris, which is troublesome to handle and pollutes the surrounding working environment. Utility Model Content

[0005] This invention addresses the technical problems of only being able to polish one side of a gear, making it impossible to polish both sides simultaneously, and the generation of debris during polishing, which leads to complicated subsequent processing and pollution of the surrounding working environment. It provides a gear surface polishing device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gear surface polishing device, comprising a base and a side plate, wherein the side plate is fixedly mounted on the upper surface of the base, and a rotating shaft is rotatably mounted on one side of the side plate; a fixing assembly for fixing a gear from the inner surface is provided at one end of the rotating shaft, and polishing heads are provided on both sides of the fixing assembly.

[0007] A collection box is fixedly installed on the upper surface of the base. A spiral tube is provided inside the collection box. A baffle is fixedly installed below the spiral tube. A feeding trough is opened at the bottom of the collection box. A storage box is inserted into the feeding trough. A magnet is magnetically attracted to the lower surface of the storage box.

[0008] Optionally, the fixing component includes a fixing block fixedly mounted on the rotating shaft, a top block slidably mounted on the side of the fixing block, an inclined block fixedly connected to one end of the top block, a threaded rod threadedly mounted on one side of the fixing block, and a push plate rotatably mounted on one end of the threaded rod.

[0009] Optionally, a support column is fixedly installed on the upper surface of the base, a support plate is fixedly installed at the top of the support column, a cylinder is fixedly installed on the upper surface of the support plate, and a storage box is fixedly installed at the output end of the cylinder.

[0010] Optionally, a bidirectional lead screw is rotatably installed inside the storage box, and a servo motor is fixedly installed on one side of the storage box. A sliding groove is opened on the lower surface of the storage box, and a slider is threaded onto the surface of the bidirectional lead screw.

[0011] Optionally, a mounting plate is fixedly installed at the bottom end of the slider, a second motor is fixedly installed on the lower surface of the mounting plate, and a polishing head is fixedly installed at the output end of the second motor.

[0012] Optionally, a fan is fixedly installed on the side of the mounting plate, a branch pipe is connected to the back of the fan, a connector is connected to the top of the collection box, the connector is connected to the branch pipe and the connector is connected to the spiral pipe, a through filter hole is opened on the surface of the baffle, and an exhaust port is opened on both sides of the collection box.

[0013] In summary, compared with the prior art, the gear surface polishing equipment provided by this utility model has the following beneficial effects:

[0014] 1. In this utility model, by rotating the threaded rod, the threaded rod is inserted forward into the fixed block, thereby pushing the push plate forward as well. This pushes the inclined block to both sides, causing the top block to extend to both sides and press against the inner surface of the gear, thus fixing it from the inside of the gear. This allows the polishing head to polish both sides of the gear simultaneously, increasing work efficiency.

[0015] 2. In this utility model, the dust generated during polishing is sucked in by a fan, and the dust enters the spiral tube through the branch pipe. Then it is collected by the baffle. After passing through the spiral tube, the dust is buffered and decelerated to prevent the dust from rebounding when passing through the baffle and sticking to the inner surface of the collection box, which would increase the trouble of subsequent cleaning.

[0016] 3. In this utility model, the cylinder drives the storage box to move downward, so that the polishing head is located on both sides of the gear. Then, the servo motor is controlled to rotate, which drives the bidirectional lead screw to rotate. While the bidirectional lead screw rotates, it drives the slider to move in the center inside the slide groove, thereby driving the polishing head to move in the center. This allows the polishing head to polish the two sides of the gear. It is also convenient for polishing different types of gears and has practicality. Attached Figure Description

Detailed Implementation

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Example 1:

[0026] refer to Figure 1 A gear surface polishing device includes a base 1, a support leg 2 fixedly installed on the lower surface of the base 1, and a side plate 3 fixedly installed on the upper surface of the base 1. A rotating shaft 5 is rotatably mounted on one side of the side plate 3, and a first motor 4 for driving the rotating shaft 5 is fixedly installed on the other side of the side plate 3.

[0027] refer to Figures 1-3 A fixing block 6 is fixedly installed at one end of the rotating shaft 5. A top block 7 is slidably installed on the upper and lower sides of the fixing block 6. The top of the top block 7 is arc-shaped. An inclined block 8 is fixedly connected to one end of the top block 7 inside the fixing block 6. A threaded rod 9 is threadedly installed on the left side of the fixing block 6. A push plate 10 is rotatably installed at one end of the threaded rod 9 located on the fixing block 6. The push plate 10 and the two inclined blocks 8 are arranged in a triangle.

[0028] Furthermore, during use, rotating the threaded rod 9 causes it to insert forward into the fixed block 6, thereby pushing the push plate 10 forward as well. This pushes the inclined block 8 to both sides, causing the top block 7 to extend to both sides and press against the inner surface of the gear, thus fixing the gear. Fixing the gear from the inside allows both surfaces of the gear to be exposed, facilitating subsequent polishing work to be carried out simultaneously from both sides of the gear, thus speeding up work efficiency.

[0029] refer to Figure 1 A support column 11 is fixedly installed at the four corners of the upper surface of the base 1. A support plate 12 is fixedly installed at the top of the support column 11. A cylinder 13 is fixedly installed on the upper surface of the support plate 12. The output end of the cylinder 13 passes through the support plate 12 and slides, and a storage box 14 is fixedly installed at the end.

[0030] refer to Figure 4 The storage box 14 has a bidirectional lead screw 15 rotatably mounted inside, and a servo motor 16 that drives the bidirectional lead screw 15 is fixedly mounted on one side of the storage box 14. A groove 17 is provided on the lower surface of the storage box 14, and a slider 18 that slides inside the groove 17 is threaded on the surface of the bidirectional lead screw 15. The sliders 18 are arranged symmetrically.

[0031] refer to Figure 1 A mounting plate 19 is fixedly installed at the bottom of the slider 18. The mounting plate 19 is L-shaped, and a second motor 20 is fixedly installed on the lower surface of the mounting plate 19. A polishing head 21 is fixedly installed at the output end of the second motor 20.

[0032] Furthermore, during use, the cylinder drives the storage box 14 to move downwards, so that the polishing head 21 is located on both sides of the gear. Then, the servo motor 16 is controlled to rotate, thereby driving the bidirectional lead screw 15 to rotate. While the bidirectional lead screw 15 rotates, it drives the slider 18 to move in the center inside the slide groove 17, thereby driving the polishing head 21 to move in the center, so that the polishing head 21 can polish the two sides of the gear. At the same time, it is convenient to polish different types of gears, which is practical.

[0033] Example 2:

[0034] refer to Figure 1A fan 23 is fixedly installed on the side of the mounting plate 19. The air inlet of the fan 23 passes through the mounting plate 19 and is matched with the polishing head 21. A branch pipe 24 is connected to the back side of the fan 23.

[0035] refer to Figure 1 and Figure 5 A collection box 22 is fixedly installed on the upper surface of the base 1. A connector 25 is connected to the top of the collection box 22 and is connected to the branch pipe 24. A spiral pipe 26 is connected to the bottom of the connector 25. Symmetrical inclined plastic baffles 27 are fixedly installed at the bottom of the inner cavity of the collection box 22. Through filter holes are opened on the surface of the baffles 27 and the baffles 27 are located below the spiral pipe 26. Exhaust vents 28 are opened on both sides of the collection box 22.

[0036] Furthermore, during use, the blower 23 sucks in the debris generated during polishing. The debris enters the spiral tube 26 through the branch pipe 24 and is then collected by the baffle 27. After passing through the spiral tube 26, the debris is buffered and slowed down to prevent it from rebounding when passing through the baffle 27 and scattering and sticking to the inner surface of the collection box 22, which would increase the trouble of subsequent cleaning. The baffle 27 is set at an angle to facilitate the falling of debris.

[0037] refer to Figure 5 and Figure 6 The bottom of the collection box 22 is provided with a discharge trough 29, which is located between two baffles 27. The lower surface of the base 1 is connected to a storage box 30 that works with the discharge trough 29. The storage box 30 is detachable, and a magnet 31 is magnetically attached to the lower surface of the storage box 30.

[0038] Furthermore, during use, the metal shavings filtered by the baffle 27 fall into the storage box 30 through the feeding chute 29, and are then attracted by the magnet block 31 to prevent the shavings from being blown away again when the fan 23 sucks them in. After the work is completed, the storage box 30 can be removed to take out the shavings.
