Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile maintenance equipment especially relates to a cvt chain repair device. BACKGROUND

[0002] CVT chain, as the core transmission element in modern continuously variable transmission (CVT), plays a crucial role. It is usually composed of a series of metal sheets connected by hinges, forming a continuous and scalable transmission belt that can smoothly transmit torque between the two pulleys of the transmission. This design enables CVT to achieve stepless speed change, thereby improving fuel efficiency, reducing emissions and enhancing driving comfort.

[0003] However, during long-term use, the working surface of the CVT chain will inevitably be subject to wear and tear. This wear and tear can be caused by a variety of factors, including continuous mechanical stress, material degradation in high-temperature environments, and increased friction due to inadequate lubrication. As the wear and tear intensifies, the working surface of the chain gradually loses its original precision and shape, affecting the performance and life of the transmission.

[0004] Traditional repair methods, such as manual grinding or simple mechanical processing, often fail to achieve the desired results. These methods often cannot accurately control the angle and fit during the repair process, resulting in the repaired chain working surface failing to maintain good contact with the pulley or other transmission elements. This not only reduces transmission efficiency, but also may cause noise, vibration and additional wear and tear, and in severe cases may even cause the transmission to fail.

[0005] In addition, traditional repair methods may also cause damage to other parts of the CVT chain. For example, excessive grinding may weaken the structural strength of the chain, increasing the risk of breakage; and inappropriate repair methods may cause the gap between the chain and the pulley to be too large, affecting the accuracy and response speed of the transmission.

[0006] Therefore, for the repair of CVT chains, we need a more accurate, efficient and reliable solution. This solution not only needs to restore the original precision and shape of the chain working surface, but also needs to ensure that the repaired chain can maintain good cooperation with other transmission elements, thereby ensuring the overall performance and life of the transmission.

DETAILED DESCRIPTION

[0030] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0031] The following description, in conjunction with the accompanying drawings, describes a CVT chain repair device according to an embodiment of the present invention.

[0032] like Figures 1-6 As shown in the figure, a CVT chain repair device according to an embodiment of the present invention includes an operating table 1, a repair device 2, a turntable device 3, and a CVT chain 4. The repair device 2 includes an adjustment component 21 and a repair component 22. The adjustment component 21 is disposed on the operating table 1, and the repair component 22 is rotatably disposed on the adjustment component 21. The turntable device 3 includes a drive component 31. The drive component 31 is rotatably disposed on the operating table 1. The CVT chain 4 is sleeved on the drive component 31, and one end of the CVT chain 4 is magnetically connected to the repair component 22.

[0033] As can be understood, the operating table 1 is the basic platform of the entire repair device, used to support and secure other components. It provides a stable working environment for the repair work.

[0034] Repair device 2 is the core component for performing CVT chain repair work, and it is further divided into two parts:

[0035] Adjustment component 21 is mounted on the operating table 1 and is used to adjust the position and angle of repair component 22 to adapt to the repair needs of different CVT chains 4. By adjusting component 21, the movement trajectory of repair component 22 can be precisely controlled, ensuring the accuracy and efficiency of the repair process.

[0036] The repair assembly 22 is rotatably mounted on the adjustment assembly 21 for direct contact with the CVT chain 4 and for performing repair work. The repair assembly 22 includes a belt sander for repair tools or surface treatment techniques to restore the performance of the CVT chain 4.

[0037] The turntable device 3 is used to support the CVT chain 4 and enable it to rotate smoothly so that the force is evenly distributed throughout the repair process.

[0038] The driving assembly 31 is rotatably arranged on the operation table 1, and is the core part of the rotating disc device 3.

[0039] The CVT chain 4 is the object to be repaired. In the present application, one end of the CVT chain 4 is magnetically connected to the repairing assembly 22, and can always closely adhere to the working surface of the CVT chain. Even if the chain moves slightly during the repairing process, the abrasive belt can still closely contact the chain, which not only improves the repairing efficiency, but also ensures the consistency and stability of the repairing quality.

[0040] Specifically, the use process is as follows:

[0041] Firstly, the CVT chain 4 to be repaired is sleeved on the driving assembly 31 of the rotating disc device 3, so as to ensure that the CVT chain 4 can rotate smoothly. Then, the position and angle of the repairing assembly 22 are adjusted through the adjusting assembly 21 of the repairing device 2 on the operation table 1, so that the repairing assembly 22 can closely adhere to the working surface of the CVT chain 4. At this time, the abrasive belt in the repairing assembly 22 is started to form contact with the CVT chain 4.

[0042] Then, the driving assembly 31 is started to keep the CVT chain 4 continuously rotating during the repairing process. Since one end of the CVT chain 4 is magnetically connected to the repairing assembly 22, even if the CVT chain 4 moves slightly during the rotating process, the repairing assembly 22 can always closely contact the CVT chain 4, so as to ensure the repairing quality and efficiency.

[0043] During the repairing process, the contact force and angle of the repairing assembly 22 can be further adjusted through the adjusting assembly 21 according to the wear condition of the CVT chain 4, so as to achieve the best repairing effect.

[0044] Finally, when the repairing work of the CVT chain 4 is completed, the driving assembly 31 and the repairing assembly 22 are closed, the CVT chain 4 is taken off from the driving assembly 31, and the quality inspection and test are carried out, so as to ensure that the performance of the CVT chain 4 has been restored to the expected level.

[0045] In an embodiment of the present application, as shown in Figure 1 and Figure 4As shown, the adjusting assembly 21 includes a stand 211, a mounting sleeve 212, a movable block 213, a mounting column 214, a mounting plate 215, a first connecting plate 216, an adjusting nut 217, a second connecting plate 218, and a first spring 219. The stand 211 is arranged on the operation table 1. The mounting sleeve 212 is slidably arranged on the stand 211 and is threadedly connected with the side wall of the stand 211. The movable block 213 is movably arranged on one side of the mounting sleeve 212. The mounting column 214 is arranged on one side of the movable block 213. The mounting plate 215 is arranged on the side wall of the mounting column 214. The first connecting plate 216 is movably arranged on the side wall of the mounting plate 215. The adjusting nut 217 is movably connected with the first connecting plate 216 through the mounting plate 215. The second connecting plate 218 is movably arranged on the first connecting plate 216. One end of the first spring 219 is connected with one end of the second connecting plate 218, and the other end of the first spring 219 is connected with the other end of the first connecting plate 216.

[0046] It can be understood that the stand 211 is a support structure of the entire adjusting assembly 21, which is firmly arranged on the operation table 1 to provide a stable mounting basis for subsequent components.

[0047] The mounting sleeve 212 is slidably arranged on the stand 211, which means that the mounting sleeve 212 can move up and down along the axial direction of the stand 211. At the same time, the mounting sleeve 212 is threadedly connected with the side wall of the stand 211, which allows the user to adjust the position of the mounting sleeve 212 on the stand 211 by rotating it and fix the position through the self-locking property of the thread.

[0048] The movable block 213 is movably arranged on one side of the mounting sleeve 212, which serves as a bridge connecting the mounting sleeve 212 and subsequent components to allow a certain angle adjustment.

[0049] The mounting column 214 is arranged on one side of the movable block 213, which further connects the movable block 213 and the subsequent mounting plate 215 to provide more structural support and flexibility for the entire adjusting assembly 21.

[0050] The mounting plate 215 is arranged on the side wall of the mounting column 214, which serves as a platform connecting the first connecting plate 216 and the repairing assembly 22. The design of the mounting plate 215 allows the first connecting plate 216 to adjust the angle on it.

[0051] The first connecting plate 216 is movably arranged on the side wall of the mounting plate 215, which allows the repairing assembly 22 to adjust the angle within a certain range in the horizontal direction.

[0052] The adjusting nut 217 is movably connected to the mounting plate 215 through the first connecting plate 216. By rotating the adjusting nut 217, the user can adjust the angle of the first connecting plate 216 relative to the mounting plate 215, thereby achieving precise angle adjustment of the repair assembly 22.

[0053] The second connecting plate 218 is movably arranged on the first connecting plate 216, which serves as a bridge connecting the repair assembly 22 and the first connecting plate 216, allowing the repair assembly 22 to be finely adjusted in the vertical direction.

[0054] One end of the first spring 219 is connected to one end of the second connecting plate 218, and the other end is connected to the other end of the first connecting plate 216. This design allows the repair assembly 22 to maintain a certain stability and buffering effect when subjected to external forces, while also providing the repair assembly 22 with certain adaptive capabilities.

[0055] In one embodiment of the present application, as shown in Figure 1 、 Figure 3 and Figure 4 , the repair assembly 22 includes a first drive motor 221, a first sand belt pulley 222, a second sand belt pulley 223, a sand belt 224, a fixed block 225, a connecting rod 226, and a magnet 227. The first drive motor 221 is arranged at one end of the mounting plate 215, the first sand belt pulley 222 is rotatably arranged at the other end of the mounting plate 215, and the first sand belt pulley 222 is connected to the output end of the first drive motor 221. The second sand belt pulley 223 is rotatably arranged on the second connecting plate 218, the sand belt 224 is sleeved on the outer side of the first sand belt pulley 222 and the second sand belt pulley 223, the fixed block 225 is arranged on the side wall of the first connecting plate 216, the connecting rod 226 penetrates through the fixed block 225, and the magnet 227 is arranged in the sand belt 224, with one end of the magnet 227 connected to the connecting rod 226.

[0056] It is understood that the first drive motor 221 is arranged at one end of the mounting plate 215 as the power source of the entire repair assembly 22. It drives the rotation of the first sand belt pulley 222 through the rotation of the output shaft, thereby driving the circular motion of the sand belt 224.

[0057] The first sand belt pulley 222 is rotatably arranged at the other end of the mounting plate 215 and connected to the output end of the first drive motor 221. When the first drive motor 221 is started, it will drive the first sand belt pulley 222 to rotate, providing power for the circular motion of the sand belt 224.

[0058] The second abrasive belt wheel 223 is rotatably arranged on the second connecting plate 218 and cooperates with the first abrasive belt wheel 222 to support the circulating movement of the abrasive belt 224. The position and angle of the second abrasive belt wheel 223 can be adjusted by the adjusting assembly 21 to adapt to the repair needs of different cvt chains 4.

[0059] The abrasive belt 224 is sleeved outside the first abrasive belt wheel 222 and the second abrasive belt wheel 223 and is a key component for performing the repair work. When the first abrasive belt wheel 222 rotates, the abrasive belt 224 will move in a cycle and contact the cvt chain 4 to remove the worn or damaged parts on the surface of the cvt chain 4.

[0060] The fixing block 225 is arranged on the side wall of the first connecting plate 216 and is used to fix the position of the connecting rod 226. The design of the fixing block 225 ensures the stability and accuracy of the connecting rod 226, thereby ensuring the effective contact of the magnet 227 with the cvt chain 4.

[0061] The connecting rod 226 penetrates through the fixing block 225 and is used to connect the magnet 227 and other parts of the repair assembly 22. The design of the connecting rod 226 enables the magnet 227 to maintain a stable position and angle during the repair of the cvt chain 4.

[0062] The magnet 227 is arranged inside the abrasive belt 224 and one end thereof is connected with the connecting rod 226. The magnet 227 is used to form a magnetic attraction connection with the cvt chain 4 to ensure that the abrasive belt 224 can be tightly attached to the working surface of the cvt chain 4 during the repair. Even if the cvt chain 4 moves slightly during the repair, the magnet 227 can maintain the close contact between the abrasive belt 224 and the cvt chain 4, thereby improving the repair efficiency and ensuring the consistency and stability of the repair quality.

[0063] In an embodiment of the present application, as shown in Figure 1 and Figure 2 The driving assembly 31 comprises a first driving wheel 311, two second driving wheels 312, a third driving wheel 313, two second springs 314 and a second driving motor 315. The first driving wheel 311 is rotatably arranged at one end of the operation table 1. The two second driving wheels 312 are rotatably arranged at the other end of the operation table 1. The third driving wheel 313 is rotatably arranged at one side of the first driving wheel 311. One end of each of the two second springs 314 is connected with the operation table 1, and the other end of each of the two second springs 314 is connected with one of the two second driving wheels 312 and one end of the third driving wheel 313. The second driving motor 315 is arranged at the bottom of the operation table 1, and the output end of the second driving motor 315 is connected with the first driving wheel 311.

[0064] The first driving wheel 311 is rotatably arranged at one end of the operation table 1 and is one of the main components for driving the rotation of the cvt chain 4.

[0065] The two second driving wheels 312 are rotatably arranged at the other end of the operation table 1 and jointly support the rotation of the cvt chain 4 with the first driving wheel 311.

[0066] The third driving wheel 313 is rotatably arranged at one side of the first driving wheel 311 and serves as an auxiliary driving wheel to further increase the stability and driving force of the rotation of the cvt chain 4.

[0067] The two second springs 314 are respectively connected to one end of the operation table 1 and the other end of one of the two second driving wheels 312 and one end of the third driving wheel 313.

[0068] The second driving motor 315 is arranged at the bottom of the operation table 1 and serves as the power source of the entire driving assembly 31.

[0069] In one embodiment of the present application, as shown in Figure 1 , Figure 2 and Figure 4 the cvt chain 4 is rotatably sleeved on the first driving wheel 311, the two second driving wheels 312 and the third driving wheel 313, and the side edges of the cvt chain 4 are magnetically connected to the magnets 227.

[0070] The cvt chain 4 is rotatably sleeved on the first driving wheel 311, the two second driving wheels 312 and the third driving wheel 313. This design ensures that the cvt chain 4 can continuously and smoothly rotate in the circumferential direction of the driving wheels during the repair process. The surface of the driving wheel is usually designed with grooves matching the cvt chain 4 to increase the transmission effect and stability.

[0071] The cvt chain 4 is magnetically attracted to the magnet 227:

[0072] In the cvt chain repair device, the side edges of the cvt chain 4 are designed to be magnetically attracted to the magnet 227 in the repair assembly 22. This design allows the magnet 227 to be closely attracted to the side edges of the cvt chain 4 during the repair process, ensuring that the abrasive belt 224 in the repair assembly 22 can always be closely attached to the contact surface of the cvt chain 4. This close fit helps improve repair efficiency and consistency of repair quality.

[0073] The magnetic attraction of the magnet 227 can be adjusted according to the material of the cvt chain 4 and the repair requirements. During the repair process, the magnet 227 will move with the rotation of the cvt chain 4 and always maintain close contact with the side edges of the cvt chain 4. This design not only improves the automation of the repair, but also reduces the labor intensity of the operator.

[0074] In one embodiment of the present application, as shown in Figure 3 , Figure 4 and Figure 5 , it further comprises a control end 5, which is electrically connected to the second drive motor 315 and the first drive motor 221 respectively.

[0075] It should be understood that the control end 5 is a PLC electronic device that integrates various control functions and display interfaces, and can accurately control and monitor various motors and actuators in the device through pre-set programs and logic.

[0076] The control end 5 is electrically connected to the second drive motor 315:

[0077] In the cvt chain repair device, the control end 5 is electrically connected to the second drive motor 315 through a cable. This connection allows the control end 5 to send start, stop, acceleration, deceleration and other control signals to the second drive motor 315, and receive feedback signals from the second drive motor 315. Through these signals, the control end 5 can accurately control the rotation speed, direction and power of the second drive motor 315, thereby achieving stable control of the rotation speed of the cvt chain 4.

[0078] The control end 5 is electrically connected to the first drive motor 221:

[0079] Similarly, the control end 5 is also electrically connected with the first driving motor 221. This connection allows the control end 5 to accurately control the first driving motor 221, including starting, stopping, adjusting the rotation speed, etc. Since the first driving motor 221 is responsible for driving the sand belt 224 in the repair assembly 22 to perform circular motion, the accurate control of the control end 5 on the first driving motor 221 is crucial to ensure the repair quality and efficiency.

[0080] It should be noted that the control method of the present application can be automatically controlled by a controller, and the control method of the controller can be realized by simple programming by those skilled in the art, which is common knowledge in the art, and the present application mainly protects the mechanical structure, so the control method and circuit connection will not be explained in detail.
