Description

Technical Field

[0001] The present invention relates to the technical field of chain guiding and connecting equipment, and particularly to an on-line guiding and connecting riveting mechanism for the timing chain of an automobile engine. Background Art

[0002] The main function of the engine timing belt is to drive the valve train of the engine, so that the engine intake and exhaust valves open or close at the appropriate time to ensure that the engine cylinders can inhale and exhaust normally. The chain drive method has reliable transmission, good durability and can also save space. The whole system consists of components such as gears, chains and tensioning devices, and is maintenance-free for life, which makes it have the same life as the engine. Not only the safety and reliability are improved to a certain extent, but also the use and maintenance costs of the engine are reduced a lot, which can be described as killing two birds with one stone.

[0003] Among them, when on-line guiding and connecting the timing chain, it is often necessary to butt the two ends of the chain together, then supplement the missing pins and chain plates, and finally connect the two ends of the chain together through a press. After the chain surrounds a circle and the head and tail ends approach each other, the position of the chain will change, and the pins may be difficult to accurately position with the chain, affecting the riveting efficiency. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides an on-line guiding and connecting riveting mechanism for the timing chain of an automobile engine, including a placement table, the top of the placement table is fixedly connected with a first electric telescopic rod, the bottom output end of the first electric telescopic rod is fixedly connected with an arc-shaped slider, and the bottom of the placement table is fixedly connected with a second electric telescopic rod;

[0005] A guiding mechanism, the guiding mechanism includes a timing chain, a motor, a transmission wheel, a transmission belt, a support wheel for guiding the timing chain, and a pushing component for connecting the timing chain;

[0006] The timing chain is placed on the top of the placement table, the bottom of the placement table is fixedly connected with the top of the motor, the number of transmission wheels is two, the outer walls of the two transmission wheels are rotatably connected to the inner wall of the placement table, and the bottom of the transmission wheel on the right is fixedly connected with the top output end of the motor;

[0007] Among them, the number of drive belts is two. The inner walls of the two drive belts are rotatably connected to the outer walls of the two drive wheels. The number of support wheels is four. The outer walls of the four support wheels are rotatably connected to the top of the placement table. The outer walls of the four support wheels are rotatably connected to the outer walls of the two drive belts. Start the first electric telescopic rod to retract, driving the arc-shaped slider to rise. The staff places the timing chain into the side wall of the drive belt from the gap after the arc-shaped slider rises. Then start the motor to drive the drive wheel to rotate, drive the drive belt to rotate through the drive wheel, and convey the timing chain. When all the timing chain enters the annular groove at the top of the placement table, extend the first electric telescopic rod again to push the arc-shaped slider down, so that the timing chain surrounds a circle, making the two ends of the timing chain approach each other until the two ends of the timing chain move to the position of the storage tank. Then stop the motor, and start the second electric telescopic rod to extend, pushing the sliding block to rise, driving the pin at the top of the spring block to rise. The sliding block will drive the connecting rod and the pressing plate to rise. When the pressing plate rises, it will squeeze the gas in the placement groove. At this time, the squeezed gas will be blocked by the spring air-blocking ring. Therefore, the gas pressure will increase. As the sliding block continues to move, the pin will contact the timing chain. When the pin aligns with the pin hole of the timing chain, it will directly insert into the timing chain. When the pin does not align with the timing chain, the pin will contact the bottom of the timing chain, causing the spring block to be squeezed and storing the resilience. At the same time, the protruding position of the convex rod on the right side will contact the spring air-blocking ring, pushing the spring air-blocking ring to rotate, so that the spring air-blocking ring stores the resilience. When the spring air-blocking ring rotates, a gap will leak out between it and the sliding cylinder. The high-pressure gas will enter the sliding cylinder through the gap, pushing the spring push rod to move and contact the pin, pushing the pin to move. After that, the protruding position of the convex rod on the right side will separate from the spring air-blocking ring, and the resilience of the spring air-blocking ring and the spring push rod will be released, causing them to return to their positions. At this time, the protruding part of the convex rod on the left side will contact the spring air-blocking ring on the left side, causing it to rotate, allowing the gas to push the spring push rod on the left side to extend and push the pin to move. In this way, it will push the pin to shake slightly, which helps to find the best alignment position with the pin hole, helps the pin find the correct position of the pin hole, and thus inserts more smoothly, realizing the precise docking of the pin and the pin hole.

[0008] Preferably, the pushing component includes two placement grooves opened on the inner wall of the placement table. A storage tank is opened on the inner wall of the placement table. A sliding block is slidably connected to the inner wall of the storage tank. The bottom of the sliding block is fixedly connected to the top output end of the second electric telescopic rod. A spring block is slidably connected to the inner wall of the sliding block;

[0009] Among them, a pressing plate is slidably connected to the inner wall of each of the two placement grooves. Connecting rods are fixedly connected to the bottoms of the two pressing plates.

[0010] Preferably, the pushing component further includes two sliding cylinders fixedly connected to the inner wall of the placement table. A spring push rod is slidably connected to the inner wall of each of the two sliding cylinders. The tops of the two connecting rods are fixedly connected to the bottom of the sliding block. A spring air-blocking ring is rotatably connected to the inner wall of each of the two sliding cylinders;

[0011] Wherein, a convex rod is fixedly connected to the top of each of the two pressing plates, and a polymerization component is arranged on the top of the placement table.

[0012] Preferably, the polymerization component includes two inclined plane blocks slidably connected to the top of the placement table. A push rod is fixedly connected to the bottom of each of the two pressing plates. Two first fixing blocks are fixedly connected to the top of the placement table. A spring push plate is arranged on the top of the placement table. The outer wall of the spring push plate is slidably connected to the inner walls of the two first fixing blocks.

[0013] Preferably, the polymerization component further includes two rollers rotatably connected to the side wall of the spring push plate. Two insertion blocks are slidably connected to the side of the spring push plate away from the rollers. Two second fixing blocks are fixedly connected to the top of the placement table. A spring concave-convex ring is slidably connected to the inner walls of the two second fixing blocks. A spring return rod is slidably connected to the inner walls of the two insertion blocks. A pressing component is arranged on the top of the placement table. When the pressing plate rises, it will also drive the push rod to rise. When the sliding block drives the pin to contact the timing chain, the push rod will also contact the inclined plane block, pushing the inclined plane block to rise, so that the inclined plane of the inclined plane block contacts the roller, pushing the roller to move towards the timing chain direction, causing the spring push plate to move. The spring push plate will drive the insertion block to move, so that the insertion block is inserted into the tooth chain gap of the timing chain. At this time, the insertion block continues to move, and the side wall of the insertion block will contact the protruding position of the spring concave-convex ring. Due to the stronger spring force of the spring concave-convex ring, the insertion block will be squeezed, causing the two insertion blocks to approach each other.

[0014] Preferably, the pressing component includes a support frame fixedly connected to the top of the placement table. An extrusion block is slidably connected to the inner wall of the support frame. A first connecting rod is rotatably connected to the top of the extrusion block. The inner wall of the first connecting rod is rotatably connected to the top of the spring push plate. Two spring pressing rods are slidably connected to the inner wall of the extrusion block. Two oil delivery pipes are connected through the inner wall of the extrusion block. When the spring push plate moves, it will push the first connecting rod to rotate. The first connecting rod will push the extrusion block to descend, approaching the timing chain. As the extrusion block continues to move, the pin will protrude from the pin hole of the timing chain. At this time, the outer link plate at the bottom of the extrusion block will be inserted onto the pin, and the spring pressing rod will contact the protruding pin.

[0015] Preferably, the pressing component further includes two tapered holes opened on the inner wall of the oil delivery pipe. A piston push rod is slidably connected to the inner wall of each of the two oil delivery pipes. A first support plate is arranged at the bottom of the extrusion block. The side wall of the piston push rod on the left is fixedly connected to the side wall of the first support plate;

[0016] Among them, two fixing frames are fixedly connected to the side wall of the extrusion block. Hydraulic oil is provided in the inner walls of the two oil pipelines, so that the spring pressure rod is extruded, causing the spring pressure rod to rise. The spring pressure rod then extrudes the hydraulic oil in the oil pipeline. The hydraulic oil will push the piston push rod to move through the tapered hole, causing the piston push rod to push the first support plate away from the outer chain plate. At the same time, the piston push rod will also push the rotating frame to rotate, causing the rotating frame to tilt, and the bottom of the rotating frame will pull the second support plate away from the outer chain plate.

[0017] Preferably, the pressing assembly further includes a rotating frame rotatably connected to the inner wall of the fixing frame. The inner walls of the two fixing frames are both slidably connected with a second support plate. The side walls of the two piston push rods are both slidably connected with the inner walls of the two rotating frames. The side walls of the two second support plates are both slidably connected with the inner walls of the two rotating frames. A feeding assembly is arranged on the side wall of the support frame to cancel the support for the outer chain plate. At this time, the top of the spring pressure rod will contact the inner wall of the top of the extrusion block, and the bottom of the spring block will contact the top of the sliding block, restricting both the extrusion block and the sliding block. As the extrusion block continues to descend, the spring pressure rod will then extrude the axle pin to rivet the axle pin, achieving the rapid riveting of the timing chain.

[0018] Preferably, the feeding assembly includes a storage frame fixedly connected to the side wall of the support frame. A pushing plate is slidably connected to the inner wall of the storage frame. A second connecting rod is rotatably connected to the side wall of the pushing plate. The side wall of the extrusion block is rotatably connected to the inner wall of the second connecting rod. An extrusion frame is fixedly connected to the top of the placement table. When the extrusion block descends, it will drive the second connecting rod to rotate, pushing the pushing plate away from the storage frame, canceling the blockage of the outer chain plate in the storage frame, causing the outer chain plate to fall. When the extrusion block rises, the second connecting rod will then pull the pushing plate close to the storage frame, pushing out the outer chain plate in the storage frame.

[0019] Preferably, the feeding assembly further includes a sliding plate slidably connected to the inner wall of the extrusion frame. The side wall of the sliding plate is fixedly connected to the side wall of the pushing plate. A spring air blocking plate is rotatably connected to the inner wall of the extrusion frame. An air injection pipe is connected through the inner wall of the extrusion frame. A fixing rod is fixedly connected to the side wall of the sliding plate, causing the outer chain plate to contact the first support plate and the second support plate again. At the same time, when the pushing plate moves away from the storage frame, it will drive the sliding plate to move, causing the fixing rod to separate from the spring air blocking plate. Since the spring air blocking plate was in a compressed state before, the resilience of the spring air blocking plate is released, causing it to return to its original position. When the pushing plate moves close to the storage frame, it will drive the sliding plate to squeeze the gas in the extrusion frame. At this time, the squeezed gas will be blocked by the spring air blocking plate.

[0020] The present invention has the following beneficial effects:

[0021] (1)When the present invention is in use, start the electric telescopic rod I to retract and drive the arc-shaped slider to rise. The staff places the timing chain into the side wall of the transmission belt from the notch after the arc-shaped slider rises. Then start the motor to drive the transmission wheel to rotate, drive the transmission belt to rotate through the transmission wheel, and convey the timing chain. After the timing chain completely enters the annular groove at the top of the placement table, extend the electric telescopic rod I again to push the arc-shaped slider to descend, so that the timing chain surrounds a circle, making the two ends of the timing chain approach each other until the two ends of the timing chain move to the position of the storage tank. Then stop the motor, and start the electric telescopic rod II to extend, push the sliding block to rise, drive the pin on the top of the spring block to rise. The sliding block will drive the connecting rod and the pressing plate to rise. The rising of the pressing plate will squeeze the gas in the placement groove. At this time, the squeezed gas will be blocked by the spring air-blocking ring. Therefore, the gas pressure will increase. As the sliding block continues to move, the pin will contact the timing chain. When the pin is aligned with the pin hole of the timing chain, it will directly insert into the timing chain. When the pin is not aligned with the timing chain, the pin will contact the bottom of the timing chain, causing the spring block to be squeezed and accumulate resilience. At the same time, the protruding position of the convex rod on the right side will contact the spring air-blocking ring, push the spring air-blocking ring to rotate, so that the spring air-blocking ring accumulates resilience. The rotation of the spring air-blocking ring will leak a gap with the sliding cylinder, and the high-pressure gas will enter the sliding cylinder through the gap, push the spring push rod to move and contact the pin, and push the pin to move. After that, the protruding position of the convex rod on the right side will separate from the spring air-blocking ring, and the resilience of the spring air-blocking ring and the spring push rod will be released, causing them to return to their original positions. At this time, the protrusion of the convex rod on the left side will contact the spring air-blocking ring on the left side, causing it to rotate, so that the gas pushes the spring push rod on the left side to extend and push the pin to move. In this way, it will push the pin to shake slightly, which helps to find the best alignment position with the pin hole, helps the pin find the correct position of the pin hole, and thus inserts more smoothly, realizing the precise docking of the pin and the pin hole.

[0022] (2) When the extrusion plate rises in the present invention, it will also drive the push rod to rise. When the sliding block drives the pin to contact the timing chain, the push rod will also contact the inclined block, pushing the inclined block to rise, so that the inclined surface of the inclined block contacts the roller, pushing the roller to move towards the timing chain direction, causing the spring push plate to move. The spring push plate will drive the insertion block to move, so that the insertion block is inserted into the tooth chain gap of the timing chain. At this time, the insertion block continues to move, and the side wall of the insertion block will contact the protruding position of the spring concave-convex ring. Since the spring force of the spring concave-convex ring is stronger, the insertion block will be squeezed, causing the two insertion blocks to approach each other. The insertion block will drive the two ends of the timing chain to approach each other, squeezing the spring return rod. When the two insertion blocks approach each other, they will tighten the timing chain until the insertion block separates from the protruding position of the spring concave-convex ring, and the resilience of the spring return rod will be released, causing the two insertion blocks to move away from each other, canceling the tension on the timing chain, thereby adjusting the distance between the pin holes at both ends of the timing chain, facilitating the insertion of the pin, and effectively preventing the distance between the pin holes at both ends of the timing chain from being too large, which affects the insertion of the pin.

[0023] (3) When the spring push plate moves in the present invention, it will push the first connecting rod to rotate. The first connecting rod will push the extrusion block to descend and approach the timing chain. As the extrusion block continues to move, the pin will protrude from the pin hole of the timing chain. At this time, the outer chain plate at the bottom of the extrusion block will be inserted onto the pin, and the spring pressure rod will contact the protruding pin, causing the spring pressure rod to be squeezed, making the spring pressure rod rise, so that the spring pressure rod squeezes the hydraulic oil in the oil delivery pipe. The hydraulic oil will push the piston push rod to move through the tapered hole, causing the piston push rod to push the first support plate to separate from the outer chain plate. At the same time, the piston push rod will also push the rotating frame to rotate, causing the rotating frame to tilt, so that the bottom of the rotating frame pulls the second support plate away from the outer chain plate, canceling the support for the outer chain plate. At this time, the top of the spring pressure rod will contact the inner wall of the top of the extrusion block, and the bottom of the spring block will contact the top of the sliding block, restricting the extrusion block and the sliding block at the same time. The extrusion block continues to descend, and the spring pressure rod will squeeze the pin, riveting the pin, and realizing the rapid riveting of the timing chain.

[0024] (4) When the extrusion block descends in the present invention, it drives the second connecting rod to rotate, pushing the material pushing plate away from the storage frame, canceling the blockage of the outer link plate in the storage frame, causing the outer link plate to fall. When the extrusion block ascends, the second connecting rod will pull the material pushing plate close to the storage frame, pushing out the outer link plate in the storage frame, making the outer link plate contact the first support plate and the second support plate again. At the same time, when the material pushing plate moves away from the storage frame, it drives the sliding plate to move, separating the fixed rod from the spring air blocking plate. Since the spring air blocking plate was in a compressed state before, the resilience of the spring air blocking plate is released, causing it to return to its original position. When the material pushing plate approaches the storage frame, it drives the sliding plate to squeeze the gas in the extrusion frame. At this time, the squeezed gas will be blocked by the spring air blocking plate, so the gas pressure will increase. As the sliding plate continues to move, the fixed rod will contact the spring air blocking plate again, causing the spring air blocking plate to rotate and cancel the blockage of the gas. The high-pressure gas will then enter the spray pipe. At this time, the sliding block will also return to its original position, and the pin in the storage groove will slide down the inclined surface of the storage groove to the top of the spring block. The high-pressure gas in the spray pipe will spray against the pin at the top of the spring block, applying an additional thrust to the pin to ensure that the pin remains vertical. Through the application of the above components, the addition of riveting materials is completed, ensuring the continuity of processing. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] Example 1, please refer to Figures 1 - 6, the present invention is an on-line guiding and riveting mechanism for the timing chain of an automobile engine, which includes a placing table 1. A first electric telescopic rod 11 is fixedly connected to the top of the placing table 1. The bottom output end of the first electric telescopic rod 11 is fixedly connected with an arc-shaped slider 12. A second electric telescopic rod 13 is fixedly connected to the bottom of the placing table 1;

[0043] A guiding mechanism 2, which includes a timing chain 21, a motor 22, a transmission wheel 23, a transmission belt 24, and a support wheel 25 for guiding the timing chain 21, and a pushing assembly 3 for loop connection of the timing chain 21;

[0044] The timing chain 21 is placed on the top of the placing table 1. The bottom of the placing table 1 is fixedly connected to the top of the motor 22. The number of the transmission wheels 23 is two. The outer walls of both transmission wheels 23 are rotatably connected to the inner wall of the placing table 1. The bottom of the transmission wheel 23 on the right side is fixedly connected to the top output end of the motor 22;

[0045] Among them, the number of transmission belts 24 is two. The inner walls of the two transmission belts 24 are rotatably connected to the outer walls of the two transmission wheels 23. The number of support wheels 25 is four. The outer walls of the four support wheels 25 are rotatably connected to the top of the placement table 1. The outer walls of the four support wheels 25 are rotatably connected to the outer walls of the two transmission belts 24. Start the first electric telescopic rod 11 to retract, driving the arc-shaped slider 12 to rise. The staff places the timing chain 21 into the side wall of the transmission belt 24 from the gap after the arc-shaped slider 12 rises. Then start the motor 22 to drive the transmission wheel 23 to rotate, and drive the transmission belt 24 to rotate through the transmission wheel 23 to convey the timing chain 21. When the timing chain 21 completely enters the annular groove at the top of the placement table 1, extend the first electric telescopic rod 11 again to push the arc-shaped slider 12 to descend, so that the timing chain 21 surrounds a circle, making the two ends of the timing chain 21 approach each other until the two ends of the timing chain 21 move to the position of the storage groove 32. Then stop the motor 22, and start the second electric telescopic rod 13 to extend, pushing the slider 321 to rise, driving the pin at the top of the spring block 33 to rise. The slider 321 will drive the connecting rod 341 and the pressing plate 34 to rise. When the pressing plate 34 rises, it will squeeze the gas in the placement groove 31. At this time, the squeezed gas will be blocked by the spring air-blocking ring 36, so the gas pressure will increase. As the slider 321 continues to move, the pin will contact the timing chain 21. When the pin is aligned with the pin hole of the timing chain 21, it will directly insert into the timing chain 21. When the pin is not aligned with the timing chain 21, the pin will contact the bottom of the timing chain 21, squeezing the spring block 33 to accumulate resilience. At the same time, the protruding position of the convex rod 37 on the right will contact the spring air-blocking ring 36, pushing the spring air-blocking ring 36 to rotate, so that the spring air-blocking ring 36 accumulates resilience. When the spring air-blocking ring 36 rotates, a gap will be leaked between it and the sliding cylinder 35, and the high-pressure gas will enter the sliding cylinder 35 through the gap, pushing the spring push rod 351 to move and contact the pin, pushing the pin to move. After that, the protruding position of the convex rod 37 on the right will separate from the spring air-blocking ring 36, and the resilience of the spring air-blocking ring 36 and the spring push rod 351 will be released, causing them to return to their original positions. At this time, the protrusion of the convex rod 37 on the left will contact the spring air-blocking ring 36 on the left, causing it to rotate, so that the gas pushes the spring push rod 351 on the left to extend and push the pin to move. Repeating this process will push the pin to shake slightly, which helps to find the best alignment position with the pin hole, helps the pin find the correct position of the pin hole, and thus inserts more smoothly, realizing the precise docking of the pin and the pin hole.

[0046] Embodiment 2. Please refer to Figures 7 - 13, the present invention is an on-line guiding ring riveting mechanism for an automotive engine timing chain. On the basis of Example 1, the pushing component 3 includes two placing grooves 31 opened at the inner wall of the placing table 1. A storage groove 32 is opened at the inner wall of the placing table 1. A sliding block 321 is slidably connected to the inner wall of the storage groove 32. The bottom of the sliding block 321 is fixedly connected to the top output end of the second electric telescopic rod 13. A spring block 33 is slidably connected to the inner wall of the sliding block 321;

[0047] Wherein, two pressing plates 34 are slidably connected to the inner walls of the two placing grooves 31. Connecting rods 341 are fixedly connected to the bottoms of the two pressing plates 34.

[0048] The pushing component 3 further includes two sliding cylinders 35 fixedly connected to the inner wall of the placing table 1. Spring push rods 351 are slidably connected to the inner walls of the two sliding cylinders 35. The tops of the two connecting rods 341 are fixedly connected to the bottom of the sliding block 321. Spring air blocking rings 36 are rotatably connected to the inner walls of the two sliding cylinders 35;

[0049] Wherein, convex rods 37 are fixedly connected to the tops of the two pressing plates 34. A polymerization component 4 is arranged on the top of the placing table 1.

[0050] The polymerization component 4 includes two inclined plane blocks 41 slidably connected to the top of the placing table 1. Pushing rods 42 are fixedly connected to the bottoms of the two pressing plates 34. Two first fixing blocks 43 are fixedly connected to the top of the placing table 1. A spring pushing plate 44 is arranged on the top of the placing table 1. The inner walls of the two first fixing blocks 43 are slidably connected to the outer wall of the spring pushing plate 44.

[0051] The polymerization component 4 further includes two rollers 45 rotatably connected to the side wall of the spring pushing plate 44. Two inserting blocks 46 are slidably connected to the side of the spring pushing plate 44 away from the rollers 45. Two second fixing blocks 47 are fixedly connected to the top of the placing table 1. Spring concave-convex rings 471 are slidably connected to the inner walls of the two second fixing blocks 47. Spring return rods 48 are slidably connected to the inner walls of the two inserting blocks 46. A pressing component 5 is arranged on the top of the placing table 1. When the pressing plate 34 rises, it will also drive the pushing rod 42 to rise. When the sliding block 321 drives the pin to contact the timing chain 21, the pushing rod 42 will also contact the inclined plane block 41, driving the inclined plane block 41 to rise, so that the inclined plane of the inclined plane block 41 contacts the roller 45, driving the roller 45 to move towards the timing chain 21, causing the spring pushing plate 44 to move. The spring pushing plate 44 will drive the inserting block 46 to move, so that the inserting block 46 is inserted into the tooth chain gap of the timing chain 21. At this time, the inserting block 46 continues to move, and the side wall of the inserting block 46 will contact the protruding position of the spring concave-convex ring 471. Since the spring force of the spring concave-convex ring 471 is stronger, the inserting block 46 will be squeezed, causing the two inserting blocks 46 to approach each other.

[0052] The pressing assembly 5 includes a support frame 51 fixedly connected to the top of the placement table 1. A pressing block 52 is slidably connected to the inner wall of the support frame 51. A first connecting rod 521 is rotatably connected to the top of the pressing block 52. The inner wall of the first connecting rod 521 is rotatably connected to the top of the spring pushing plate 44. Two spring pressing rods 53 are slidably connected to the inner wall of the pressing block 52. Two oil delivery pipes 54 penetrate through the inner wall of the pressing block 52. When the spring pushing plate 44 moves, it will push the first connecting rod 521 to rotate. The first connecting rod 521 will push the pressing block 52 to descend and approach the timing chain 21. As the pressing block 52 continues to move, the pin will protrude from the pin hole of the timing chain 21. At this time, the outer link plate at the bottom of the pressing block 52 will be inserted onto the pin, and the spring pressing rod 53 will contact the protruding pin.

[0053] The pressing assembly 5 further includes two tapered holes 541 formed in the inner wall of the oil delivery pipe 54. A piston push rod 55 is slidably connected to the inner wall of each of the two oil delivery pipes 54. A first support plate 56 is provided at the bottom of the pressing block 52. The side wall of the piston push rod 55 on the left is fixedly connected to the side wall of the first support plate 56.

[0054] Among them, two fixing frames 57 are fixedly connected to the side wall of the pressing block 52. Hydraulic oil is provided in the inner wall of each of the two oil delivery pipes 54, so that the spring pressing rod 53 is squeezed, causing the spring pressing rod 53 to rise. The spring pressing rod 53 squeezes the hydraulic oil in the oil delivery pipe 54. The hydraulic oil will push the piston push rod 55 to move through the tapered hole 541, causing the piston push rod 55 to push the first support plate 56 away from the outer link plate. At the same time, the piston push rod 55 will also push the rotating frame 571 to rotate, causing the rotating frame 571 to tilt, and the bottom of the rotating frame 571 will pull the second support plate 58 away from the outer link plate.

[0055] The pressing assembly 5 further includes a rotating frame 571 rotatably connected to the inner wall of the fixing frame 57. A second support plate 58 is slidably connected to the inner wall of each of the two fixing frames 57. The side walls of the two piston push rods 55 are slidably connected to the inner walls of the two rotating frames 571. The side walls of the two second support plates 58 are slidably connected to the inner walls of the two rotating frames 571. A feeding assembly 6 is provided on the side wall of the support frame 51 to cancel the support for the outer link plate. At this time, the top of the spring pressing rod 53 will contact the inner wall of the top of the pressing block 52, and the bottom of the spring block 33 will contact the top of the sliding block 321, restricting both the pressing block 52 and the sliding block 321. The pressing block 52 continues to descend, and the spring pressing rod 53 will squeeze the pin to rivet the pin, achieving rapid riveting of the timing chain 21.

[0056] The feeding component 6 includes a storage frame 61 fixedly connected to the side wall of the support frame 51. A pushing plate 62 is slidably connected to the inner wall of the storage frame 61. A second connecting rod 621 is rotatably connected to the side wall of the pushing plate 62. The side wall of the extrusion block 52 is rotatably connected to the inner wall of the second connecting rod 621. A pressing frame 63 is fixedly connected to the top of the placing table 1. When the extrusion block 52 descends, it will drive the second connecting rod 621 to rotate, pushing the pushing plate 62 away from the storage frame 61, canceling the blockage of the outer chain plate in the storage frame 61, and causing the outer chain plate to fall. When the extrusion block 52 ascends, the second connecting rod 621 will pull the pushing plate 62 close to the storage frame 61, pushing out the outer chain plate in the storage frame 61.

[0057] The feeding component 6 further includes a sliding plate 64 slidably connected to the inner wall of the pressing frame 63. The side wall of the sliding plate 64 is fixedly connected to the side wall of the pushing plate 62. A spring air-blocking plate 65 is rotatably connected to the inner wall of the pressing frame 63. An air injection pipe 66 is connected through the inner wall of the pressing frame 63. A fixing rod 641 is fixedly connected to the side wall of the sliding plate 64, making the outer chain plate contact the first support plate 56 and the second support plate 58 again. At the same time, when the pushing plate 62 moves away from the storage frame 61, it will drive the sliding plate 64 to move, separating the fixing rod 641 from the spring air-blocking plate 65. Since the spring air-blocking plate 65 was in a compressed state before, the resilience of the spring air-blocking plate 65 is released, causing it to return to its original position. When the pushing plate 62 approaches the storage frame 61, it will drive the sliding plate 64 to squeeze the gas in the pressing frame 63. At this time, the squeezed gas will be blocked by the spring air-blocking plate 65.

[0058] The quantity of the above components is not limited. Those skilled in the relevant art can freely set it according to actual needs, as long as the above components are installed at the corresponding component connection positions.

[0059] A specific application of this embodiment is as follows: When the present invention is in use, the electric telescopic rod 11 is started to retract, driving the arc-shaped slider 12 to rise. The staff places the timing chain 21 from the gap after the rise of the arc-shaped slider 12 to the side wall of the transmission belt 24. Then, the motor 22 is started to drive the transmission wheel 23 to rotate, and the transmission belt 24 is driven to rotate by the transmission wheel 23 to convey the timing chain 21. After the timing chain 21 completely enters the annular groove at the top of the placement table 1, the electric telescopic rod 11 is extended again to push the arc-shaped slider 12 to descend, so that the timing chain 21 makes a full circle, and the two ends of the timing chain 21 approach each other until the two ends of the timing chain 21 move to the position of the storage groove 32. Then, the motor 22 is stopped, and the electric telescopic rod 2 is started to extend, pushing the slider 321 to rise, driving the pin on the top of the spring block 33 to rise. The slider 321 will drive the connecting rod 341 and the pressing plate 34 to rise. When the pressing plate 34 rises, it will squeeze the gas in the placement groove 31. At this time, the squeezed gas will be blocked by the spring air-blocking ring 36, so the gas pressure will increase. As the slider 321 continues to move, the pin will contact the timing chain 21. When the pin aligns with the pin hole of the timing chain 21, it will directly insert into the timing chain 21. When the pin does not align with the timing chain 21, the pin will contact the bottom of the timing chain 21, causing the spring block 33 to be squeezed and storing the resilience. At the same time, the protruding position of the convex rod 37 on the right will contact the spring air-blocking ring 36, pushing the spring air-blocking ring 36 to rotate, so that the spring air-blocking ring 36 stores the resilience. When the spring air-blocking ring 36 rotates, a gap will leak out between it and the sliding cylinder 35, and the high-pressure gas will enter the sliding cylinder 35 through the gap, pushing the spring push rod 351 to move and contact the pin, pushing the pin to move. After that, the protruding position of the convex rod 37 on the right will separate from the spring air-blocking ring 36, and the resilience of the spring air-blocking ring 36 and the spring push rod 351 will be released, causing them to return to their positions. At this time, the protrusion of the convex rod 37 on the left will contact the spring air-blocking ring 36 on the left, causing it to rotate, and the gas will push the spring push rod 351 on the left to extend and push the pin to move. In this way, the pin will be pushed to shake slightly, which helps to find the best alignment position with the pin hole, helps the pin find the correct position of the pin hole, so as to insert more smoothly, realizing the precise docking of the pin and the pin hole, and then riveting processing is carried out;

[0060] Among them, after the pin is inserted into the pin hole, the spring push rod 351 extends and cannot push the pin to move. As the pressing plate 34 continues to rise, multiple protrusions on the convex rod 37 will all separate from the spring air-blocking ring 36, causing the spring push rod 351 to return to its position, enabling the slider 321 to rise smoothly;

[0061] Secondly, when the extrusion plate 34 rises, it will also drive the push rod 42 to rise. When the sliding block 321 drives the pin to contact the timing chain 21, the push rod 42 will also contact the inclined plane block 41, pushing the inclined plane block 41 to rise, so that the inclined plane of the inclined plane block 41 contacts the roller 45, pushing the roller 45 to move towards the timing chain 21, causing the spring push plate 44 to move. The spring push plate 44 will drive the insertion block 46 to move, so that the insertion block 46 is inserted into the tooth chain gap of the timing chain 21. At this time, the insertion block 46 continues to move, and the side wall of the insertion block 46 will contact the protruding position of the spring concave-convex ring 471. Since the spring force of the spring concave-convex ring 471 is stronger, the insertion block 46 will be squeezed, causing the two insertion blocks 46 to approach each other. The insertion block 46 will drive the two ends of the timing chain 21 to approach each other, squeezing the spring return rod 48. When the two insertion blocks 46 approach each other, the timing chain 21 will be tightened until the insertion block 46 separates from the protruding position of the spring concave-convex ring 471, and the resilience of the spring return rod 48 will be released, causing the two insertion blocks 46 to move away from each other, canceling the tightening of the timing chain 21, thereby adjusting the distance between the pin holes at both ends of the timing chain 21, facilitating the insertion of the pin, and effectively preventing the excessive distance between the pin holes at both ends of the timing chain 21 from affecting the insertion of the pin;

[0062] Among them, when the pin is inserted into the pin hole, when the insertion block 46 contacts the protruding position of the spring concave-convex ring 471, the insertion block 46 cannot push the timing chain 21 to move, and the insertion block 46 will push the spring concave-convex ring 471 to move, so that the spring concave-convex ring 471 accumulates resilience, enabling the insertion block 46 to move smoothly during the rising process of the pin;

[0063] Secondly, when the spring push plate 44 moves, it will push the first connecting rod 521 to rotate. The first connecting rod 521 will push the extrusion block 52 to descend, approaching the timing chain 21. As the extrusion block 52 continues to move, the pin will protrude from the pin hole of the timing chain 21. At this time, the outer link plate at the bottom of the extrusion block 52 will be inserted onto the pin, and the spring pressure rod 53 will contact the protruding pin, causing the spring pressure rod 53 to be squeezed, making the spring pressure rod 53 rise, squeezing the hydraulic oil in the oil delivery pipe 54. The hydraulic oil will push the piston push rod 55 to move through the tapered hole 541, causing the piston push rod 55 to push the first support plate 56 to separate from the outer link plate. At the same time, the piston push rod 55 will also push the rotating frame 571 to rotate, causing the rotating frame 571 to tilt, so that the bottom of the rotating frame 571 pulls the second support plate 58 away from the outer link plate, canceling the support for the outer link plate. At this time, the top of the spring pressure rod 53 will contact the inner wall of the top of the extrusion block 52, and the bottom of the spring block 33 will contact the top of the sliding block 321, restricting both the extrusion block 52 and the sliding block 321 at the same time. As the extrusion block 52 continues to descend, the spring pressure rod 53 will squeeze the pin to rivet the pin, achieving the rapid riveting of the timing chain 21;

[0064] Wherein, after the riveting is completed, the electric telescopic rod two 13 retracts, driving the sliding block 321 and the extrusion plate 34 to descend. Then, the push rod 42 will separate from the inclined plane block 41, releasing the extrusion on the spring push plate 44. The resilience of the spring push plate 44 will be released, causing the spring push plate 44 to return to its original position, raising the extrusion block 52. As the extrusion block 52 rises, the spring pressure rod 53 will separate from the pin. The resilience of the spring pressure rod 53 is released, causing it to return to its original position and canceling the extrusion on the hydraulic oil, attracting the piston push rod 55 to return. Since the tapered hole 541 is tapered, when the hydraulic oil passes through the small hole to the large hole, the flow rate of the hydraulic oil will be slowed down, thereby slowing down the return speed of the piston push rod 55 and preventing the support plate one 56 and the support plate two 58 from moving to the bottom of the outer link plate again when they rise;

[0065] Secondly, when the extrusion block 52 descends, it will drive the link two 621 to rotate, pushing the pushing plate 62 away from the storage frame 61, canceling the block on the outer link plate in the storage frame 61, and causing the outer link plate to fall. When the extrusion block 52 rises, the link two 621 will pull the pushing plate 62 closer to the storage frame 61, pushing out the outer link plate in the storage frame 61, and making the outer link plate contact the support plate one 56 and the support plate two 58 again. At the same time, when the pushing plate 62 moves away from the storage frame 61, it will drive the sliding plate 64 to move, separating the fixed rod 641 from the spring air blocking plate 65. Since the spring air blocking plate 65 was in a compressed state before, the resilience of the spring air blocking plate 65 is released, causing it to return to its original position. When the pushing plate 62 moves closer to the storage frame 61, it will drive the sliding plate 64 to squeeze the gas in the extrusion frame 63. At this time, the squeezed gas will be blocked by the spring air blocking plate 65, so the gas pressure will increase. As the sliding plate 64 continues to move, the fixed rod 641 will contact the spring air blocking plate 65 again, causing the spring air blocking plate 65 to rotate and canceling the block on the gas. The high-pressure gas will then enter the spray pipe 66. At this time, the sliding block 321 will also return to its original position, and the pin in the storage groove 32 will slide down the inclined plane of the storage groove 32 to the top of the spring block 33. The high-pressure gas in the spray pipe 66 will spray out against the pin on the top of the spring block 33, applying an additional thrust to the pin to ensure that the pin remains vertical. Through the application of the above components, the addition of riveting materials is completed, ensuring the continuity of processing.
