Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of welding, in particular to a shock absorber piston rod welding device and a motorcycle shock absorber with an auxiliary damping mechanism. BACKGROUND

[0002] The shock absorber piston rod is a key component in the motorcycle shock absorber, and its main function is to transmit force and motion, and to guide during the working process of the shock absorber. The piston rod is usually made of high-strength steel to withstand various forces and impacts generated during vehicle driving. During manufacturing, the piston rod needs to be welded. The core function of the shock absorber piston rod welding device is to use laser welding to firmly combine the various components to form a complete piston rod.

[0003] However, in the prior art, the piston rod needs to be welded with an external snap ring to prevent axial movement and ensure normal operation of the shock absorber. Usually, a spot welding machine is used to spot weld the piston rod and the snap ring to ensure that the snap ring does not shift during subsequent complete welding. Then, the weld is completely welded. Usually, the piston rod is placed manually for welding, but the efficiency of manual placement is relatively low, and each piston rod needs to be manually positioned and adjusted by an operator, which not only consumes time but also cannot meet the high efficiency requirements of mass production. In addition, the precision of manual placement is limited and affected by the skills and experience of the operator, which can cause the snap ring to deviate in position and affect the welding quality and overall performance of the shock absorber. To solve these shortcomings, manufacturers have begun to consider introducing automated equipment. The automated equipment can automatically feed, position, weld and detect the piston rod, greatly improving production efficiency and reducing human interference to ensure welding precision and consistency. However, such equipment requires high equipment costs and complex technical maintenance requirements, and often requires manual removal of the welded piston rod, affecting the continuity of production.

[0004] Therefore, the shock absorber piston rod welding device and the motorcycle shock absorber with an auxiliary damping mechanism are proposed, which can facilitate automatic feeding and discharging. SUMMARY

[0009] Further, the limiting piece comprises an arc sleeve arranged in the C-shaped frame, a strip-shaped plate connected to one side of the arc sleeve, a second spring connected between the strip-shaped plate and the support plate, and a circular shaft fixedly connected to one side of the strip-shaped plate, the other side of the strip-shaped plate is attached to the arc sleeve, one end of the reinforcing rod penetrates through the arc sleeve and the strip-shaped plate, the side of the arc sleeve close to the workpiece is a fillet surface, the elastic coefficients of the second springs are smaller than that of the first spring.

[0010] Further, the outside of the workpiece is provided with a sleeve ring, the welding head is arranged close to the sleeve ring, and the inner diameter of the arc sleeve is equal to the diameter of the sleeve ring.

[0011] Further, the two reinforcing rods are symmetric about the central axis of the circular shaft, the top and the bottom of the C-shaped frame are each provided with a plurality of sliding grooves, and one end of the reinforcing rod and the circular shaft are each horizontally and slidably connected to the inside of the sliding grooves.

[0012] Furthermore, the push rod includes a square rod slidably connected to the top of the inclined plate, and an inner arc push block fixedly connected to one side of the square rod.

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] Example 1, referring to Figures 1-11 This invention provides a shock absorber piston rod welding device, comprising a support frame 1, a welding device 2 and a mounting base 3 fixedly mounted on the top of the support frame 1, and a conveyor 4 mounted on the top of the mounting base 3. The welding device 2 is located on one side of the mounting base 3, and a welding head 21 is provided on the top of the welding device 2. A servo motor 31 is provided on the top of the mounting base 3, and a connecting shaft 311 is fixedly connected to the output end of the servo motor 31. A locking member 5 is provided at one end of the connecting shaft 311, and a bracket 6 is fixedly connected to the connecting shaft 311. A limiting member 7 is slidably connected inside the locking member 5. Two brackets 6 and limiting members 7 are provided and are symmetrical about the central axis of the connecting shaft 311. A limiting sleeve 8 and a push rod 9 are provided on one side of the locking member 5. An inclined plate 10 and a placement box 11 are fixedly connected to the top of the mounting base 3. The limiting sleeve 8 and the push rod... The limit sleeve 8 and push rod 9 are slidably connected to the top of the inclined plate 10. The sliding directions of the limit sleeve 8 and push rod 9 are perpendicular to each other. The push rod 9 passes through the placement box 11. The top of the mounting base 3 is fixedly connected to the first telescopic device 12 and the second telescopic device 13. The output end of the first telescopic device 12 is fixedly connected to the push rod 9, and the output end of the second telescopic device 13 is fixedly connected to the limit sleeve 8. The top of the push rod 9 is where the workpiece 14 is placed. There are two reinforcing rods 15 connecting the limit member 7 and the locking member 5. When the first telescopic device 12 is fully extended, the locking member 5 fixes the workpiece 14 through the reinforcing rods 15 and the limit member 7. The workpiece 14 can be placed into the interior of the placement box 11 in batches using conventional equipment or manually. Ladders can also be set up to integrate the feeding, positioning and welding processes into one, which not only improves production efficiency but also reduces the equipment footprint and operational complexity.

[0035] Reference Figures 1-3 The locking component 5 includes a C-shaped frame 51 disposed on one side of the connecting shaft 311, a sliding block 52 fixedly connected to the C-shaped frame 51 near the connecting shaft 311, and a first spring 53 connected between the C-shaped frame 51 and the connecting shaft 311. The sliding block 52 is slidably connected inside the connecting shaft 311. A conventional arc, i.e. a limiting ring, is provided on the outside of the connecting shaft 311 to limit the sliding distance of the sliding block 52. When the servo motor 31 drives the connecting shaft 311 to rotate, the servo motor 31 causes the locking component 5 to rotate as a whole through the strips on both sides of the sliding block 52, thereby causing the limiting component 7 to drive the workpiece 14 to rotate one revolution, and the welding head 21 is used to weld the weld seam.

[0036] Reference Figures 1-7 The bracket 6 includes a support rod 61 fixedly connected inside the connecting shaft 311, two connecting frames 62 respectively connected to both sides of the support rod 61, and a support plate 63 connected between the two support rods 61. The reinforcing rod 15 is vertically slidably connected inside the support plate 63. When the limiting member 7 is squeezed and moved, it will drive the reinforcing rod 15 to move synchronously. The support plate 63 restricts the reinforcing rod 15 and the limiting member 7, so that the reinforcing rod 15 and the limiting member 7 can only move up and down, ensuring that the limiting member 7 can stably limit the vertical position of the workpiece 14.

[0037] Reference Figures 2-5 The limiting component 7 includes an arc sleeve 71 disposed inside the C-shaped frame 51, a strip plate 72 connected to one side of the arc sleeve 71, a second spring 73 connected between the strip plate 72 and the support plate 63, and a round shaft 74 fixedly connected to one side of the strip plate 72. The other side of the strip plate 72 is in contact with the arc sleeve 71. One end of the reinforcing rod 15 passes through the arc sleeve 71 and the strip plate 72. The side of the arc sleeve 71 near the workpiece 14 has a rounded corner surface 711, which facilitates the compression of the workpiece 14. The second spring 73 and the first spring 53 have strong elastic coefficients. The elastic coefficient of the first spring 53 is greater than the elastic coefficients of the two second springs 73, thereby ensuring that the first spring 53 has strong elastic force and can push the workpiece 14. When the workpiece 14 is pushed back by the first spring 53, it is disengaged from the arc sleeve 71 by inertia, thereby achieving automatic disengagement, which can improve the welding strength of the workpiece 14 after welding.

[0038] Specifically, when the workpiece 14 loses the support of the square rod 91, the workpiece 14 no longer presses against the C-shaped frame 51. At this time, the rebound force generated by the first spring 53 will push the workpiece 14 back completely into the interior of the limiting sleeve 8. At this time, the arc sleeve 71 will not contact the limiting sleeve 8. Then, the limiting sleeve 8 can be used to drive the workpiece 14 to the top of the inclined plate 10.

[0039] Reference Figures 2-6The outer side of the workpiece 14 is provided with a collar 141, the welding head 21 is located near the collar 141, and the inner diameter of the arc sleeve 71 is equal to the diameter of the collar 141.

[0040] The two reinforcing rods 15 are symmetrical about the central axis of the round shaft 74. The top and bottom of the C-shaped frame 51 are provided with multiple sliding slots 511. One end of the reinforcing rods 15 and the round shaft 74 are horizontally slidably connected inside the sliding slots 511.

[0041] Specifically, when the C-shaped frame 51 moves, the round shaft 74 and the reinforcing rod 15 will not move, but the relative position of the slide opening 511 with the round shaft 74 and the reinforcing rod 15 will change. Eventually, the end point of the inner wall of the slide opening 511 will squeeze the round shaft 74 and the reinforcing rod 15, so that the two are completely joined together, and the round shaft 74 and the reinforcing rod 15 will be unable to move.

[0042] Reference Figures 1-8 The push rod 9 includes a square rod 91 slidably connected to the top of the inclined plate 10, and an inner arc push block 92 fixedly connected to one side of the square rod 91. The interior of the square rod 91 has the same shape and size as one end of the workpiece 14, and the workpiece 14 can be placed inside the square rod 91. The interior of the square rod 91 is smooth, which allows the workpiece 14 to move inside the square rod 91. When the square rod 91 moves towards the C-shaped frame 51, the square rod 91 will push the workpiece 14. However, when the square rod 91 moves back, the workpiece 14 cannot move back with the square rod 91. The inner arc push block 92 penetrates the interior of the placement box 11. Since the length inside the placement box 11 is equal to the length of the workpiece 14, when multiple workpieces 14 are located inside the placement box 11, the workpieces 14 will be restricted by the placement box 11 and can only move up and down, ensuring that the workpieces 14 fall accurately into the interior of the square rod 91.

[0043] When the inner arc push block 92 slides inside the placement box 11, the inner arc push block 92 will squeeze the processing part 14 above the inside of the placement box 11, so that the processing part 14 inside the placement box 11 will not move down. The processing part 14 inside the placement box 11 will only move down when the square rod 91 reaches the inside of the placement box 11.

[0044] Reference Figures 1-11 The interior of the limiting sleeve 8 is divided into an arc surface 81 and a vertical surface 82. The diameter of the arc surface 81 is the same as the diameter of the collar 141, ensuring stable restriction of the collar 141. The vertical surface 82 is located below the arc surface 81. Both sides of the interior of the limiting sleeve 8 are vertical surfaces 82, thereby restricting both sides of the workpiece 14 and preventing the workpiece 14 from shifting, so that the workpiece 14 can only move downward. When the limiting sleeve 8 pulls the workpiece 14 to move, the workpiece 14 will automatically slide above the inclined plate 10.

[0045] Specifically, the circular arc surface 81 restricts the collar 141, thereby cooperating with the square rod 91 to ensure that the workpiece 14 is always restricted during movement, and the workpiece 14 will not deviate during movement, so that the workpiece 14 can accurately enter between the two arc sleeves 71.

[0046] Reference Figures 1-11 The reinforcing rod 15 includes a screw 151 threaded between the arc sleeve 71 and the strip plate 72, and a bar shaft 152 fixedly connected to one side of the screw 151. The arc sleeve 71 is a mold. When dealing with piston rods of different diameters, the arc sleeve 71 needs to be replaced. The arc sleeve 71 can be disassembled using the screw 151 for easy replacement. At the same time, the length of the slide groove 511 needs to be adjusted according to the distance between the workpiece 14 and the collar 141 to ensure that when the first telescopic device 12 is fully extended, the C-shaped frame 51 can fix the bar shaft 152 and the round shaft 74.

[0047] Example 2, refer to Figures 1-11 The first embodiment of the present invention provides a motorcycle shock absorber with an auxiliary shock absorption mechanism, including a housing 16, a machined part 14 placed inside the housing 16 during use, an interface block 17 provided at one end of the machined part 14, a shock absorption spring 18 connected between the interface block 17 and the housing 16, and a cooling component 19 provided on the outside of the housing 16, which can cool the housing 16 to ensure the shock absorption effect and prevent the machined part 14 and the housing 16 from overheating.

[0048] The working principle of this invention is as follows: Multiple processed parts 14 are placed inside the placement box 11. At this time, the lowest processed part 14 will fall above the square rod 91, and one end of the processed part 14 will enter the interior of the square rod 91. Then, the first telescopic device 12 is activated to pull the inner arc push block 92, so that the inner arc push block 92 and the square rod 91 move synchronously towards the C-shaped frame 51. The processed parts 14 located inside the square rod 91 also move synchronously. When the processed parts 14 move synchronously with the square rod 91 and the inner arc push block 92, the processed parts 14 and the processed parts 14 outside them will enter the interior of the limiting sleeve 8. The collar 141 will fit against the arc surface 81 inside the limiting sleeve 8. The limiting sleeve 8 restricts the processed parts 14 and prevents the processed parts 14 from shifting. As the workpiece 14 moves under the continuous push of the push rod 9, one end of the workpiece 14 contacts the interior of the C-shaped frame 51. The collar 141 then presses against the rounded corner surface 711 of the arc sleeve 71, causing the arc sleeve 71 to move vertically. The arc sleeve 71 drives the strip plate 72, the round shaft 74, and the reinforcing rod 15 to move synchronously. Simultaneously, the movement of the arc sleeve 71 compresses the second spring 73. Because one end of the workpiece 14 contacts the C-shaped frame 51, the workpiece 14 presses against the C-shaped frame 51 during its movement, causing the C-shaped frame 51 to move the sliding block 52. At the same time, the C-shaped frame 51 compresses the first spring 53. At this point, the relative positions of the sliding groove 511, the reinforcing rod 15, and the round shaft 74 during the movement of the C-shaped frame 51 are... This will also change. As the workpiece 14 moves, the collar 141 will enter between the two arc sleeves 71, and the collar 141 will be clamped by the two arc sleeves 71. At the same time, due to the compression of the C-shaped frame 51 by the workpiece 14, the reinforcing rod 15 and the round shaft 74 will first contact the end of the slide groove 511. Then the C-shaped frame 51 will still move a short distance, and the C-shaped frame 51 will compress the reinforcing rod 15 and the round shaft 74 to fix them together. At this time, the first expansion joint 12 is fully extended, and the C-shaped frame 51 is also in contact with the limiting ring of the connecting shaft 311 and cannot move, so that the workpiece 14 is restricted between the square rod 91 and the C-shaped frame 51. At the same time, the outside of the collar 141 is also restricted by the two arc sleeves 71 and cannot move, but can only rotate. At this time, welding is used to fix the collar 14. Equipment 2 drives the welding head 21 to the weld seam between the workpiece 14 and the collar 141, and then drives the servo motor 31 to rotate the connecting shaft 311. The connecting shaft 311 causes the locking member 5 and the bracket 6 to rotate as a whole, and the limiting member 7 also rotates as a whole. At this time, the limiting member 7 also drives the collar 141 and the workpiece 14 to rotate, thereby completing the weld seam. Then the first telescopic device 12 retracts, and the square rod 91 and the inner arc push block 92 move back. However, due to the low friction caused by the smooth internal treatment of the inner arc push block 92, and because the workpiece 14 is located between the two arc sleeves 71, the workpiece 14 cannot move back with the square rod 91. However, since one end of the workpiece 14 loses the support of the square rod 91, the first spring 53 rebounds, causing the workpiece 14 to move back.The collar 141 disengages from the arc sleeve 71, but due to the rapid return movement of the C-shaped frame 51 under the influence of the first spring 53, it impacts the workpiece 14, causing the workpiece 14 to fully enter the interior of the limiting sleeve 8. Then, the second telescopic device 13 pushes the limiting sleeve 8 to move, which in turn moves the welded workpiece 14. Since there is no obstruction below the limiting sleeve 8, when the workpiece 14 is no longer supported, it slides above the inclined plate 10, and then above the conveyor 4. The conveyor 4 transports the welded workpiece 14, and then the second telescopic device 13 pulls the limiting sleeve 8 back. The square rod 91 then pushes the next falling workpiece 14 for welding.
