Description

Technical Field

[0001] This utility model relates to the field of polishing technology, specifically a polishing device for a motorcycle clutch cover. Background Technology

[0002] The motorcycle clutch cover is the outer shell that protects the core components of the clutch. It is usually made of aluminum alloy, cast iron or engineering plastic, combining lightweight and high strength. Its surface is often treated with polishing, spraying and other processes to enhance wear resistance, corrosion resistance and aesthetics. Some high-performance models also use hollowed-out designs, heat dissipation fins and other designs to help dissipate heat from the clutch and ensure smooth and reliable gear shifting. It is an indispensable protective component in the motorcycle transmission system.

[0003] The processing of clutch housings usually begins with selecting the process based on the material. For metal materials such as aluminum alloy and cast iron, casting blanks are often used. After aging treatment to eliminate stress, machining such as turning, milling, and drilling is used to ensure assembly accuracy. After forming, grinding and polishing are required to remove burrs and machining marks. Then, surface treatments such as spraying anti-rust paint, electroplating, or anodizing are used to enhance corrosion resistance and aesthetics. Finally, after passing airtightness and dimensional accuracy tests, the housing is packaged and shipped.

[0004] In existing motorcycle clutch covers, surface polishing is mostly performed by professionals using grinding wheels, resulting in low polishing efficiency. Therefore, to address this issue, a polishing device for motorcycle clutch covers is proposed. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A polishing device for a motorcycle clutch cover, comprising a worktable; a first support frame fixedly connected to the top of the worktable; a first slider slidably connected to the top of the first support frame; an electric push rod fixedly connected to the bottom of the first slider; a motor fixedly connected to the output end of the electric push rod; a top plate fixedly connected to the output end of the motor; a second slider slidably connected to the top of the worktable; a rotating shaft rotatably connected to the top of the second slider; a connecting rod fixedly connected to the top of the second slider; a first slider fixedly connected to the top of the connecting rod; and a polishing wheel fixedly connected to the top of the worktable. By pressing down the top of the cover and supporting the bottom positioning structure of the cover with the rotating shaft, the clutch cover can be stably clamped at the center of rotation, reducing uneven surface polishing or damage caused by shaking during polishing. The synchronous rotation of the top plate and the rotating shaft can align the cover with the polishing wheel, improving polishing accuracy. Pushing the first and second sliders to slide makes the cover contact with the rotating polishing wheel, so that the polishing force is evenly applied to the surface of the cover, increasing the quality of the cover polishing.

[0007] Preferably, a second support frame is fixedly connected to the top of the workbench; a spring-damped telescopic rod is fixedly connected to the middle of the second support frame; a polishing wheel is fixedly connected to the top of the spring-damped telescopic rod; a first slide rail is fixedly connected to the top of the workbench; a third slider is slidably connected to the top of the first slide rail; a polishing wheel is connected to the top of the third slider; the elastic contraction of the spring-damped telescopic rod can automatically adjust the contact pressure between the outer cover and the polishing wheel when the connecting rod pushes the outer cover to contact the polishing wheel. When the thrust is too large, the elastic deformation of the spring-damped telescopic rod absorbs the impact force, reducing polishing defects such as dents on the surface of the outer cover caused by the pressure of the polishing wheel, and ensuring that the surface finish of the outer cover is uniform.

[0008] Preferably, a pair of second slide rails are fixedly connected to the top of the worktable; a collection box is slidably connected to the top of the second slide rails; the collection boxes are symmetrically arranged on the top of the worktable; a magnetic block is fixedly connected to the side wall of the collection box; by symmetrically arranging the collection boxes on the side of the polishing wheel, the polishing debris is directly dropped into the middle of the second slide rail due to centrifugal force, and pushing the collection box can shorten the distance of the debris to fall or splash, reducing the contamination of the worktable surface by the debris.

[0009] Preferably, an air pump is fixedly connected to the top of the workbench; an air pipe is fixedly connected to the top of the air pump; an air nozzle is fixedly connected to the top of the air pipe; a fixing plate is fixedly connected to the top of the workbench; and an air pipe is slidably connected to the middle of the fixing plate. By spraying compressed air onto the surface of the clutch cover through the air nozzle before polishing, contaminants such as dust and metal particles attached to the surface can be blown away, ensuring that the polishing wheel directly contacts the surface of the cover during polishing and improving the uniformity of the polishing gloss.

[0010] Preferably, a paint pump is fixedly connected to the top of the workbench; a container is fixedly connected to the top of the workbench; the paint pump and the container are arranged correspondingly; a spray pipe is fixedly connected to the side wall of the paint pump; multiple sets of nozzles are fixedly connected to the top of the spray pipe; a coating layer is immediately sprayed through the nozzles after polishing, which can form a protective film on the surface, further increasing the quality of the outer cover surface and increasing the corrosion resistance of the outer cover during subsequent use.

[0011] Preferably, a first friction pad is fixedly connected to the bottom end of the top plate; a second friction pad is fixedly connected to the top end of the rotating shaft; by having the first and second friction pads contact the bottom and top of the outer cover respectively, the outer cover is stably fixed above the rotating shaft by increasing the friction force when the top plate rotates, effectively reducing the phenomenon of the outer cover shifting, slipping or falling off due to uneven force during the polishing process.

[0012] The advantages of this utility model are: 1. The present invention relates to a polishing device for a motorcycle clutch cover, wherein the top plate presses down on the top of the cover and the rotating shaft supports the bottom positioning structure of the cover, which can stably clamp the clutch cover at the center of rotation, reducing uneven surface polishing or damage caused by shaking during polishing. The synchronous rotation of the top plate and the rotating shaft can align the cover with the polishing wheel, improving polishing accuracy. Pushing the first slider and the second slider to slide makes the cover contact with the rotating polishing wheel, so that the polishing force is evenly applied to the surface of the cover, increasing the quality of the cover polishing.

[0013] 2. The polishing device for a motorcycle clutch cover described in this utility model can automatically adjust the contact pressure between the cover and the polishing wheel when the connecting rod pushes the cover to contact the polishing wheel by the elastic contraction of the spring damping telescopic rod. When the thrust is too large, the elastic deformation of the spring damping telescopic rod absorbs the impact force, reducing polishing defects such as dents on the surface of the cover caused by the pressure of the polishing wheel, and ensuring that the surface finish of the cover is uniform.

[0017] 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 scope of protection of the present utility model.

[0018] Specific implementation examples are given below.

[0019] like Figures 1 to 5 As shown in the embodiment of this utility model, a polishing device for a motorcycle clutch cover includes a worktable 1; a first support frame 11 is fixedly connected to the top of the worktable 1; a first slider 12 is slidably connected to the top of the first support frame 11; an electric push rod 13 is fixedly connected to the bottom of the first slider 12; a motor 14 is fixedly connected to the output end of the electric push rod 13; a top plate 15 is fixedly connected to the output end of the motor 14; a second slider 16 is slidably connected to the top of the worktable 1; a rotating shaft 17 is rotatably connected to the top of the second slider 16; a connecting rod 18 is fixedly connected to the top of the second slider 16; the first slider 12 is fixedly fixed to the top of the connecting rod 18; and a polishing wheel 19 is fixedly connected to the top of the worktable 1. During operation, the clutch cover to be polished is placed on top of the rotating shaft 17. After the cover is placed, the electric push rod 13 below the first slider 12 is pushed, causing the motor 14 to move closer to the cover above the rotating shaft 17, so that the top plate 15 contacts the top of the cover, and the top plate 15 presses down on the rotating shaft. The outer cover at the top of the 17 can position the outer cover. After the outer cover is fixed, a pushing force can be applied to the connecting rod 18 to drive the first slider 12 and the second slider 16 to slide, so that the outer cover placed on the top of the rotating shaft 17 contacts the rotating polishing wheel 19 and polishes the outer cover above the rotating shaft 17. When the outer cover is polished, the motor 14 can be started to drive the top plate 15 to rotate, which in turn drives the outer cover to rotate. The bottom of the outer cover contacts the rotating shaft 17, and the rotating shaft 17 rotates synchronously, so that the rotation of the outer cover and the rotation of the polishing wheel 19 cooperate to polish. By pressing down the top of the outer cover by the top plate 15 and the rotating shaft 17 supporting the bottom positioning structure of the outer cover, the clutch outer cover can be stably clamped in the center of rotation, reducing uneven surface polishing or damage caused by shaking during polishing. The synchronous rotation of the top plate 15 and the rotating shaft 17 can make the outer cover and the polishing wheel 19 aligned, improving the polishing accuracy. Pushing the first slider 12 and the second slider 16 to slide makes the outer cover contact the rotating polishing wheel 19, so that the polishing force is evenly applied to the surface of the outer cover, increasing the quality of the outer cover polishing.

[0020] like Figure 1 and Figure 3As shown, a second support frame 2 is fixedly connected to the top of the workbench 1; a spring-damped telescopic rod 21 is fixedly connected to the middle of the second support frame 2; a polishing wheel 19 is fixedly connected to the top of the spring-damped telescopic rod 21; a first slide rail 22 is fixedly connected to the top of the workbench 1; a third slider 23 is slidably connected to the top of the first slide rail 22; the polishing wheel 19 is connected to the top of the third slider 23; during operation, when the polishing wheel 19 polishes the outer cover, the thrust of the connecting rod 18 will squeeze the polishing wheel 19, and a large thrust will cause defects in the polishing of the outer cover. When the connecting rod 18 pushes the outer cover to contact the polishing wheel 19, the spring-damped telescopic rod 21 can retract elastically, causing the third slider 23 to slide along the first slide rail 22. The elastic retraction of the spring-damped telescopic rod 21 can automatically adjust the contact pressure between the outer cover and the polishing wheel 19 when the connecting rod 18 pushes the outer cover to contact the polishing wheel 19. When the thrust is too large, the elastic deformation of the spring-damped telescopic rod 21 absorbs the impact force, reducing the polishing defects such as dents on the surface of the outer cover caused by the pressure of the polishing wheel 19, and ensuring that the surface finish of the outer cover is uniform.

[0021] like Figure 1 and Figure 2 As shown, a pair of second slide rails 3 are fixedly connected to the top of the workbench 1; a collection box 31 is slidably connected to the top of the second slide rails 3; the collection box 31 is symmetrically arranged on the top of the workbench 1; a magnetic block 32 is fixedly connected to the side wall of the collection box 31; during operation, when the polishing wheel 19 polishes the outer cover above the rotating shaft 17, the polishing debris can fall into the middle of the collection box 31. Applying a pushing force to the collection box 31 can move the collection box 31 closer to the polishing wheel 19, so that the polishing wheel 19 collects the debris at a shorter distance. After the debris is collected into the collection box 31, the magnetic block 32 can attract the debris; because the collection box 31 is symmetrically arranged on the side of the polishing wheel 19, the polishing debris falls directly into the middle of the second slide rail 3 due to centrifugal force. Pushing the collection box 31 can shorten the distance of the debris falling or splashing, and reduce the debris contamination of the surface of the workbench 1.

[0022] like Figure 1 and Figure 4 As shown, an air pump 4 is fixedly connected to the top of the workbench 1; an air pipe 42 is fixedly connected to the top of the air pump 4; an air jet nozzle 43 is fixedly connected to the top of the air pipe 42; a fixing plate 41 is fixedly connected to the top of the workbench 1; and the air pipe 42 is slidably connected to the middle of the fixing plate 41. During operation, before polishing the outer cover above the rotating shaft 17, the air pump 4 can be started to drive the air jet nozzle 43 to spray air, which, together with the motor 14, drives the outer cover to rotate, thus removing contaminants from the surface of the outer cover. By spraying compressed air onto the surface of the clutch outer cover through the air jet nozzle 43 before polishing, contaminants such as dust and metal particles attached to the surface can be blown away, ensuring that the polishing wheel 19 directly contacts the surface of the outer cover during polishing, thereby improving the uniformity of the polishing gloss.

[0023] like Figure 1 and Figure 5 As shown, a paint pump 5 is fixedly connected to the top of the workbench 1; a container 51 is fixedly connected to the top of the workbench 1; the paint pump 5 and the container 51 are arranged correspondingly; a spray pipe 52 is fixedly connected to the side wall of the paint pump 5; multiple sets of nozzles 53 are fixedly connected to the top of the spray pipe 52; during operation, after the outer cover surface is polished, the paint pump 5 can be started to spray the liquid inside the container 51 evenly onto the outer cover surface from the multiple sets of nozzles 53, thus spraying the outer cover surface; the coating layer sprayed immediately after polishing through the nozzles 53 can form a protective film on the surface, further increasing the quality of the outer cover surface and increasing the corrosion resistance of the outer cover during subsequent use.

[0024] like Figure 1 and Figure 4 As shown, a first friction pad 6 is fixedly connected to the bottom end of the top plate 15; a second friction pad 61 is fixedly connected to the top end of the rotating shaft 17. During operation, the first friction pad 6 and the second friction pad 61 can contact the bottom and top of the outer cover, respectively. When the top plate 15 rotates, the friction force is increased, making the outer cover stable above the rotating shaft 17. By having the first friction pad 6 and the second friction pad 61 contact the bottom and top of the outer cover respectively, the friction force is increased when the top plate 15 rotates, and the outer cover is firmly fixed above the rotating shaft 17, effectively reducing the phenomenon of the outer cover shifting, slipping or falling off due to uneven force during the polishing process.

[0025] Working principle: The clutch cover to be polished is placed on top of the rotating shaft 17. After the cover is placed, the electric push rod 13 below the first slider 12 is pushed, which drives the motor 14 to approach the cover above the rotating shaft 17, so that the top plate 15 contacts the top of the cover. The top plate 15 presses down on the cover at the top of the rotating shaft 17 to position the cover. After the cover is fixed, a pushing force can be applied to the connecting rod 18 to drive the first slider 12 and the second slider 16 to slide, so that the outer shell placed on top of the rotating shaft 17 contacts the rotating polishing wheel 19 to polish the cover above the rotating shaft 17. When the cover is polished, the motor 14 can be started to drive the top plate 15 to rotate, which in turn drives the cover to rotate. The bottom of the cover contacts the rotating shaft 17, and the rotating shaft 17 rotates synchronously, so that the rotation of the cover and the rotation of the polishing wheel 19 cooperate to polish. When the polishing wheel 19 polishes the cover, the pushing force of the connecting rod 18 will squeeze the polishing wheel 19. A large pushing force will cause defects in the polishing of the cover. At this time, when the connecting rod 18 pushes the cover to contact the polishing wheel 19, the spring... The spring-damped telescopic rod 21 can retract elastically, causing the third slider 23 to slide along the first slide rail 22. When the polishing wheel 19 polishes the outer cover above the rotating shaft 17, the polishing debris can fall into the middle of the collection box 31. Applying a pushing force to the collection box 31 can move the collection box 31 closer to the polishing wheel 19, making the distance at which the polishing wheel 19 collects debris closer. After the debris is collected inside the collection box 31, the magnetic block 32 can attract the debris. Before polishing the outer cover above the rotating shaft 17, the air pump 4 can be started to drive the air jet 43 to spray air. In conjunction with the motor 14 to drive the outer cover to rotate, the contaminants on the surface of the outer cover can be removed. After the outer cover surface is polished, the paint pump 5 can be started to spray the liquid inside the container 51 evenly onto the outer cover surface from multiple sets of nozzles 53. The first friction pad 6 and the second friction pad 61 can contact the bottom and top of the outer cover. When the top plate 15 rotates, the friction increases, making the outer cover stable above the rotating shaft 17.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
