Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to a feeding device for CVT transmission chain processing that prevents belt slippage. Background Technology

[0002] The CVT drive chain is a core power transmission component of a continuously variable transmission (CVT). It is a high-precision automotive part composed of multiple precision metal chain links connected by pins. Its machining accuracy directly determines the transmission efficiency, noise control, and service life of the transmission. Therefore, it has extremely high requirements for the positioning accuracy, synchronization, and stability of the feeding mechanism. Thus, a CVT drive chain feeding device that prevents belt slippage is needed to eliminate positioning errors caused by belt slippage during the feeding process, thereby ensuring product processing consistency, improving production yield, and meeting the cycle time requirements of automated production lines.

[0003] Early feeding devices consisted of a drive motor, a flat belt, and a carrying platform. The motor provided power, and the flat belt relied on friction to transmit power and transport the workpiece. However, when transporting a chain load with high inertia, the flat belt would slip, resulting in inaccurate feeding length and poor positioning accuracy, thus producing a batch of scrap. To solve these problems, existing technology uses raised textures on the surface of the belt and rollers to increase friction, and an adjustable tension screw to adjust the belt tension and maintain tension, thereby alleviating the slippage problem. However, in actual use, because it is impossible to monitor the chain pitch in real time during the conveying process, it is impossible to detect and correct slippage or pitch deviations caused by manufacturing errors of the chain itself in time, thus failing to guarantee the final conveying accuracy and failing to meet the user's needs.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the rotating lead screw is driven to move vertically through the threaded connection with the support plate. The lead screw can make the bracket and the pressure roller move up and down through the connecting piece, which can adapt to transmission chains of different thicknesses. When the pressure roller contacts the chain, it increases the contact pressure between the chain and the belt, improves the friction and prevents slippage. At the same time, the chain conveying will drive the pressure roller to rotate synchronously. The photoelectric sensor can detect the deviation of the chain pitch in time to ensure the chain conveying accuracy.

In this utility model, rotating the bidirectional lead screw causes the two sets of sliders to slide synchronously in opposite directions, thereby driving the mounting shell at the bottom of the slider and the guide roller to adjust the distance synchronously. It can be adapted and adjusted according to the width of the chain to form a guiding effect of clamping on both sides. When the chain deviates during the conveying process, the guide roller is pushed by the side of the chain, causing the connecting plate to slide along the inner wall of the mounting shell. The spring is used for buffering, and at the same time, the chain deviates. Attached Figure Description

[0032] 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.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The present invention provides an embodiment of a CVT transmission chain processing and feeding device for preventing belt 9 slippage, comprising a frame 1 and a belt 9. The frame 1 is the basic load-bearing structure of the entire device. Side plates 4 are fixedly connected to the front and rear sides of the top of the frame 1. A detection mechanism 2 is provided on the top right side of the rear side plate 4, and guide mechanisms 3 are provided on the top left and right sides of the two side plates 4.

[0034] The detection mechanism 2 includes a support plate 201, which serves as the support for the detection mechanism 2 and ensures vertical accuracy. The bottom of the support plate 201 is fixedly connected to the top right end of the rear side plate 4. A bracket 202 is provided on the inner bottom of the support plate 201, which serves as the mounting carrier for the pressure roller 207. A limit frame 203 is fixedly connected to the top of the bracket 202. A lead screw 204 is threadedly connected to the top of the support plate 201. The lead screw 204 is threadedly engaged with the top of the support plate 201 and can move vertically by rotation, providing adjustment for the height of the pressure roller 207. The bottom end of the lead screw 204 passes through the top of the support plate 201 and the limit frame 203 and is fixedly connected to a connecting piece 205. Plate 205 serves as the upper support point for spring 209. Simultaneously, when lead screw 204 rises, it can drive limit frame 203 to rise via connecting plate 205. Spring 209 is fixedly connected to the bottom of connecting plate 205. The bottom of spring 209 is fixedly connected to the top of bracket 202. The pressure of spring 209 ensures that pressure roller 207 is in close contact with the chain. Rotary shaft 206 is rotatably connected to the inner side of bracket 202. Rotary shaft 206 ensures that pressure roller 207 rotates smoothly. Pressure roller 207 is fixedly connected to the outer wall of rotary shaft 206. Pressure roller 207 rotates synchronously with the chain through friction. Photoelectric sensor 208 is provided at the front end of bracket 202. Photoelectric sensor 208 provides data for pitch calculation.

[0035] Guide posts 5 are fixedly connected to the front and rear sides of the top of the bracket 202. The top of the two guide posts 5 penetrates the top of the inner side of the support plate 201. The guide posts 5 restrict the bracket 202 to move only vertically.

[0036] Specifically, for transmission chains of different thicknesses, rotating the lead screw 204 causes the threaded connection between the lead screw 204 and the support plate 201 to move the lead screw 204 vertically. When the lead screw 204 moves upward, the connecting piece 205 connected to the bottom of the lead screw 204 drives the limiting frame 203 to rise. The limiting frame 203 then drives the bracket 202 and the pressure roller 207 to rise. Conversely, when the lead screw 204 moves downward, the pressure roller 207 will descend synchronously, thus adapting to transmission chains of different thicknesses. When the guide post 5 moves the bracket 202 up and down, it ensures that the bracket 202 moves smoothly only vertically. When the pressure roller 207 contacts the chain, the bracket 202 drives the spring 209 to rise. The connecting piece 205 at the top of the spring 209 remains fixed to the lead screw 204, therefore the spring 209... 9 generates compression, producing continuous downward pressure through elastic deformation, causing the pressure roller 207 to tightly adhere to the upper surface of the chain, increasing the contact pressure between the chain and belt 9, improving static friction, and preventing chain slippage. Simultaneously, during chain conveying, the pressure roller 207 rotates synchronously. The photoelectric sensor 208 at the front end of the bracket 202 is aligned with the side of the chain. When the chain is conveyed by belt 9, the protrusions of each chain link block the detection light path of the photoelectric sensor 208, generating a pulse signal. Combined with the synchronous rotation of the pressure roller 207's shaft 206, the system can confirm stable conveying speed. By statistically analyzing the time interval between two adjacent pulse signals and calculating the chain pitch based on the conveying speed, the system can detect when the pitch exceeds the preset tolerance, providing real-time feedback to the control system to adjust the conveying speed or trigger an alarm to ensure chain conveying accuracy.

[0037] Reference Figure 1 , Figure 2 and Figure 4The guide mechanism 3 includes two mounting brackets 301, which serve as mounting frames 14 for the bidirectional lead screw 302 and sliders 303. The bottom front and rear sides of the two mounting brackets 301 are fixedly connected to the top left and right sides of the corresponding side plates 4, respectively. The bidirectional lead screw 302 is rotatably connected inside both mounting brackets 301. When the bidirectional lead screw 302 rotates, it causes the two sets of sliders 303 to move synchronously in opposite directions. The bottom of both mounting brackets 301 is provided with a sliding groove 304, which restricts the sliders 303 to slide only laterally. The front and rear sides of the outer walls of the two bidirectional lead screws 302 are threaded with sliders 303. The sliders 303 move linearly through the rotation of the bidirectional lead screw 302, driving the mounting shell 305 to move. The bottom left and right sides of the multiple sliders 303 are slidably connected to the inner walls of the corresponding sliding grooves 304, respectively. The bottom of the multiple sliders 303 is fixedly connected to the mounting shell 305, which is a connecting... The connecting plate 306 provides a sliding guide. The inner walls of multiple mounting shells 305 are slidably connected to the connecting plate 306. The connecting plate 306 is the connecting carrier between the guide roller 307 and the second spring 3081. The bottom of the multiple connecting plates 306 is rotatably connected to the guide roller 307. The interior of the multiple mounting shells 305 is provided with a buffer assembly 308. The buffer assembly 308 includes multiple second springs 3081. One end of each second spring 3081 is fixedly connected to one side of the corresponding connecting plate 306. The other end of each second spring 3081 is fixedly connected to one side of the inner wall of the corresponding mounting shell 305. When the chain deviates, the second spring 3081 generates a reverse elastic force through compression. The bottom side of each of the multiple mounting shells 305 is provided with a second groove 3082. The second groove 3082 restricts the connecting plate 306 to move only laterally. The front and rear sides of the multiple connecting plates 306 are slidably connected to the inner wall of the corresponding second groove 3082.

[0038] Specifically, rotating the bidirectional lead screw 302 inside the mounting bracket 301 causes the reverse thread of the bidirectional lead screw 302 to drive the two sets of sliders 303 to slide synchronously in opposite directions along the slide groove 304 at the bottom of the mounting bracket 301. The slide groove 304 limits the sliders 303, allowing them to move only laterally to prevent deviation. This, in turn, drives the mounting shell 305 at the bottom of the sliders 303 and the guide roller 307 to adjust their spacing synchronously. This device can be adapted to the width of the chain to form a guiding effect that clamps both sides of the chain. During chain conveying, the chain deviates to one side and comes into contact with the guide roller 307 on the corresponding side. The guide roller 307 will start to rotate under the lateral thrust of the chain, and at the same time push the connecting plate 306 to slide along the inner wall of the mounting shell 305. During the sliding process, the connecting plate 306 will compress the spring 3081 inside the mounting shell 305, which plays a buffering role. At the same time, the reverse elastic force of the spring 3081 will reset the guide roller 307 and correct the chain deviation.

[0039] Reference Figure 1 , Figure 5 and Figure 6 Two side plates 4 are rotatably connected to the right end of adjacent sides with the same driving roller 6. Two side plates 4 are provided with driven rollers 8 on the left end of adjacent sides. The driving roller 6 and driven roller 8 are connected by a belt 9. A servo motor 7 is fixedly connected to the right front end of the front side plate 4. The output end of the servo motor 7 passes through the front side of the corresponding side plate 4 and is fixedly connected to the front end of the driving roller 6. The servo motor 7 provides power, causing the driving roller 6 and driven roller 8 to rotate synchronously through friction via the belt 9. Multiple friction grooves 10 are provided on the outer walls of both the driving roller 6 and driven roller 8. The friction grooves 10 increase the static friction between the roller and the belt 9, preventing slippage. Two side plates 4 are provided with guide grooves 16 on adjacent left ends. The guide grooves 16 restrict the driven roller 8 to move only in the left and right directions. The front and rear ends of the outer walls of the driven roller 8 are slidably connected to the inner walls of the corresponding guide grooves 16. The left ends of the two side plates 4... Frames 14 are fixedly connected to the opposite sides of the two screw rods 17 and the moving blocks 15. The moving blocks 15 are slidably connected to the inner sides of the two frames 14. The moving blocks 15 convert the rotational motion of the screw rod 17 into the linear motion of the driven roller 8. The adjacent sides of the two moving blocks 15 are fixedly connected to the front and rear ends of the driven roller 8, respectively. The left ends of the two frames 14 are threadedly connected to the screw rod 17. When the screw rod 17 rotates, it pushes the driven roller 8 to move, thereby realizing the fine adjustment of the tension of the belt 9. The right ends of the two screw rods 17 pass through the left ends of the corresponding frames 14 and the moving blocks 15, respectively, and are fixedly connected to the limit plates 18. The right side of the outer wall of the two screw rods 17 is threadedly connected to the adjusting nuts 19, and the left side of the outer wall of the two screw rods 17 is threadedly connected to the locking nuts 20. After the locking nuts 20 are tightened, the screw rod 17 is fixed by friction.

[0040] Specifically, after the servo motor 7 starts, it drives the active roller 6 to rotate. The active roller 6 drives the driven roller 8 to rotate synchronously through the friction of the belt 9, forming the belt 9 transmission system. The servo motor 7 can precisely control the speed of the active roller 6 to ensure that the conveying speed of the belt 9 is adapted to the speed requirements of CVT chain processing. At the same time, the multiple friction grooves 10 on the outer wall of the active roller 6 and the driven roller 8 can increase the contact friction between the roller body and the inner side of the belt 9 to avoid slippage. The front and rear ends of the driven roller 8 are embedded in the guide grooves 16 of the two side plates 4. The guide grooves 16 restrict the driven roller 8 to slide only in the left and right direction. When the belt 9 becomes loose after long-term use, the screw 17 on the two side frames 14 is rotated. The threaded connection with the frame 14 will push the moving block 15 to slide along the inner side of the frame 14. The moving block 15 drives the driven roller 8 to move away from the active roller 6 along the guide groove 16, thereby lengthening the belt 9 to achieve tension. During the adjustment process, the advance distance of the screw 17 can be locked by adjusting the distance nut 19. Finally, tighten the locking nut 20 to fix the position of the screw 17 and ensure the stability of the belt 9.

[0041] Reference Figure 5 and Figure 6The bottom right end of the two side plates 4 is fixedly connected to the same fixed frame 21. The fixed frame 21 serves as the installation reference for the cleaning brush 22. The cleaning brush 22 is fixedly connected to the inner side of the fixed frame 21. The brush head of the cleaning brush 22 contacts the lower surface of the return section of the belt 9 and scrapes off the surface metal dust as the belt 9 rotates. Multiple connecting blocks 12 are fixedly connected to the bottom of adjacent sides of the two side plates 4. Multiple support rollers 13 are provided at the bottom of the belt 9. The support rollers 13 roll in contact with the lower surface of the belt 9 to prevent the middle section of the belt 9 from sagging. The front and rear ends of the multiple support rollers 13 are rotatably connected to one side of the corresponding connecting block 12. The top of adjacent sides of the two side plates 4 is fixedly connected to the same support plate 11. The support plate 11 contacts the top inner side of the belt 9 to provide support and ensure the flatness of the conveying surface.

[0042] Specifically, the fixed frame 21 provides support for the cleaning brush 22. The cleaning brush 22 contacts the lower surface of the return section of the belt 9. When the belt 9 circulates with the drive roller 6 and the driven roller 8, the return section of the belt 9 contacts the cleaning brush 22, which can scrape off the metal dust or oil stains attached to the surface of the belt 9, avoiding the risk of slippage caused by dust residue. The connecting blocks 12 on the inner side of the two side plates 4 are evenly distributed to provide a rotation fulcrum for the support roller 13. The support roller 13 makes rolling contact with the lower surface of the belt 9. When the belt 9 conveys the chain, the support roller 13 counteracts the sagging force of the belt 9 through rolling support, increasing the tension of the belt 9. The support plate 11 fits against the inner top of the belt 9, providing support for the top of the belt 9 through surface contact, ensuring the flatness of the conveying surface of the belt 9, and avoiding contact deviation between the chain and the detection mechanism 2 due to undulation of the conveying surface.

[0043] Working Principle: For CVT transmission chains of different thicknesses, rotating the lead screw 204 causes the threaded connection between the lead screw 204 and the support plate 201 to move the lead screw 204 vertically. When the lead screw 204 moves upward, the connecting piece 205 at the bottom drives the limiting frame 203 to rise, which in turn drives the bracket 202 and the pressure roller 207 to rise. Conversely, when the lead screw 204 moves downward, the pressure roller 207 descends synchronously. This design can accommodate transmission chains of different thicknesses. The guide post 5 ensures that the bracket 202 moves smoothly only vertically when it moves up and down. When the pressure roller 207 contacts the chain, the bracket 202 drives the spring 209 to rise. Since the connecting piece 205 at the top of the spring 209 is fixed to the lead screw 204, the spring 209 is compressed, and the elasticity is utilized to release the spring's energy. The deformation generates continuous downward pressure, causing the pressure roller 207 to fit tightly against the upper surface of the chain, increasing the contact pressure between the chain and the belt 9, improving static friction and preventing slippage. At the same time, the chain conveying will drive the pressure roller 207 to rotate synchronously. The photoelectric sensor 208 at the front end of the bracket 202 is aligned with the side of the chain. The links of the CVT chain are periodically distributed. When the chain is conveyed with the belt 9, the protrusion of each link will block the detection light path of the photoelectric sensor 208, generating a pulse signal. Combined with the synchronous rotation of the shaft 206 of the pressure roller 207, the conveying speed is confirmed to be stable. The system calculates the chain pitch by statistically analyzing the time interval between two adjacent pulse signals and based on the conveying speed. If the pitch exceeds the preset tolerance, the mechanism will provide real-time feedback to the control system to adjust the conveying speed or trigger an alarm to ensure the chain conveying accuracy.

[0044] Furthermore, rotating the bidirectional lead screw 302 inside the mounting bracket 301 causes the reverse thread of the bidirectional lead screw 302 to drive the two sets of sliders 303 to slide synchronously in the opposite direction along the slide groove 304 at the bottom of the mounting bracket 301. The slide groove 304 restricts the sliders 303 to move only laterally to avoid deviation, thereby driving the mounting shell 305 at the bottom of the sliders 303 and the guide roller 307 to adjust their spacing synchronously. This allows for adaptation and adjustment according to the width of the chain, forming a guiding effect of clamping on both sides. During chain conveying, when the chain deviates to one side and contacts the guide roller 307 on the corresponding side, the guide roller 307 rotates under the lateral thrust of the chain, simultaneously pushing the connecting plate 306 to slide along the inner wall of the mounting shell 305. During the sliding process, the connecting plate 306 compresses the second spring 3081 inside the mounting shell 305 for buffering. At the same time, the reverse elastic force of the second spring 3081 resets the guide roller 307 and corrects the chain deviation.
