Description

Technical Field

[0001] The invention relates to the technical field of welding, in particular to shock absorber piston rod welding equipment and a motorcycle shock absorber with an auxiliary shock absorbing mechanism. Background Art

[0002] The shock absorber piston rod is a key component in the motorcycle shock absorber. Its main function is to transmit force and motion, as well as to play a guiding role in the operation of the shock absorber. The piston rod is usually made of high-strength steel to withstand the various forces and impacts generated during the vehicle's driving. The piston rod needs to be welded during manufacturing. By using the shock absorber piston rod welding equipment, its core function is to use laser welding to firmly combine the various components to form a complete piston rod.

[0003] However, in the prior art, the welding work needs to weld the piston rod to the external retaining ring to prevent axial movement and ensure the normal operation of the shock absorber. Usually, the piston rod and the retaining ring are fixed by spot welding with a spot welding machine to ensure that the retaining ring will not be displaced during the subsequent complete welding process, and then the weld is completely welded. Usually, the piston rod is manually placed for welding. However, due to the relatively low efficiency of manual placement, each piston rod requires manual positioning and adjustment by the operator, which is not only time-consuming but also difficult to meet the high efficiency requirements of large-scale production. Secondly, the accuracy of manual placement is limited, and it is affected by the skills and experience of the operator, which easily leads to deviations in the position of the retaining ring, thereby affecting the welding quality and the overall performance of the shock absorber. In order to solve these shortcomings, manufacturers began to consider introducing automated equipment. Automated equipment can realize automatic feeding, positioning, welding and detection of piston rods, greatly improve production efficiency, reduce interference from human factors, and ensure welding accuracy and consistency. However, such equipment requires high equipment costs and complex technical maintenance requirements, and most of them also require manual removal of welded piston rods, affecting production continuity.

DETAILED DESCRIPTION

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0034] Example 1, reference Figure 1-Figure 11 , which is the first embodiment of the present invention, provides a shock absorber piston rod welding device, including a support frame 1, a welding device 2 and a mounting seat 3 fixedly arranged on the top of the support frame 1, and a conveyor 4 arranged on the top of the mounting seat 3, the welding device 2 is located on one side of the mounting seat 3, a welding head 21 is arranged on the top of the welding device 2, a servo motor 31 is arranged on the top of the mounting seat 3, the output end of the servo motor 31 is fixedly connected to a connecting shaft 311, a locking member 5 is arranged at one end of the connecting shaft 311, a bracket 6 is fixedly connected to the connecting shaft 311, the locking member 5 is internally slidably connected to a limiting member 7, two brackets 6 and limiting members 7 are arranged and are symmetrical about the central axis of the connecting shaft 311, a limiting sleeve 8 and a push rod 9 are arranged 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 seat 3, the limiting sleeve 8 and the push rod 9 9 are all slidably connected to the top of the inclined plate 10, the sliding directions of the limit sleeve 8 and the push rod 9 are perpendicular to each other, the push rod 9 passes through the placement box 11, the top of the mounting seat 3 is fixedly connected with the first telescope 12 and the second telescope 13, the output end of the first telescope 12 is fixedly connected to the push rod 9, the output end of the second telescope 13 is fixedly connected to the limit sleeve 8, a workpiece 14 is placed on the top of the push rod 9, two reinforcement rods 15 are connected between the limit member 7 and the locking member 5, when the first telescope 12 is fully extended, the locking member 5 fixes the workpiece 14 through the reinforcement rod 15 and the limit member 7, wherein the workpiece 14 can be placed into the interior of the placement box 11 by conventional equipment or manual batches, and a ladder can also be set, so as to integrate the loading, positioning, and welding links, which not only improves the production efficiency, but also reduces the equipment footprint and operation complexity.

[0035] Reference Figure 1-Figure 3 The locking member 5 includes a C-shaped frame 51 arranged on one side of the connecting shaft 311, a sliding block 52 fixedly connected to the C-shaped frame 51 on one side close to the connecting shaft 311, a first spring 53 connected between the C-shaped frame 51 and the connecting shaft 311, the sliding block 52 is slidably connected to the inside of the connecting shaft 311, and a conventional arc, i.e., a limiting ring, is arranged 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 rotates the locking member 5 as a whole through the bars on both sides of the sliding block 52, so that the limiting member 7 drives the workpiece 14 to rotate one circle, and the welding head 21 is used to weld the weld.

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

[0037] Reference Figure 2-Figure 5 The limit member 7 includes an arc sleeve 71 arranged 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 fitted 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 close to the workpiece 14 is a rounded surface 711, which is convenient for squeezing 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 a strong elastic force and can push the workpiece 14. When the workpiece 14 is pushed back by the first spring 53, it is inertial and disengaged from the arc sleeve 71, thereby achieving automatic disengagement, thereby being able to 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 the C-shaped frame 51. At this time, the rebound force generated by the first spring 53 will push the workpiece 14 completely back to the inside of the limit sleeve 8. At this time, the arc sleeve 71 will not contact the limit sleeve 8, and the limit sleeve 8 can be used to drive the workpiece 14 to the top of the inclined plate 10.

[0039] Reference Figure 2-Figure 6A collar 141 is disposed outside the workpiece 14 , the welding head 21 is located close to 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 circular shaft 74 . A plurality of slide slots 511 are provided at the top and bottom of the C-shaped frame 51 . The reinforcing rods 15 and one end of the circular shaft 74 are horizontally slidably connected inside the slide slots 511 .

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

[0042] Reference Figure 1-Figure 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. The end of the workpiece 14 can be placed inside the square rod 91. At the same time, the interior of the square rod 91 is smooth, which enables the workpiece 14 to move inside the square rod 91. When the square rod 91 moves toward the C-shaped frame 51, the square rod 91 will push the workpiece 14, but when the square rod 91 moves back, the workpiece 14 cannot move back with the square rod 91. The inner arc push block 92 runs through the interior of the placement box 11. Since the length of the interior of 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 workpiece 14 will be restricted by the placement box 11 and can only move up and down, ensuring that the workpiece 14 accurately falls into the interior of the square rod 91.

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

[0044] Reference Figure 1-Figure 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 ring 141, ensuring stable restriction of the ring 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 to prevent the workpiece 14 from deviating, 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 to the top of the inclined plate 10.

[0045] Specifically, the collar 141 is restricted by the arc surface 81 , thereby cooperating with the square rod 91 , so that the workpiece 14 is always restricted when moving, the workpiece 14 will not be offset when moving, and the workpiece 14 can accurately enter between the two arc sleeves 71 .

[0046] Reference Figure 1-Figure 11 The reinforcing rod 15 includes a screw 151 threadedly connected between the arc sleeve 71 and the strip plate 72, and a strip shaft 152 fixedly connected to one side of the screw 151, wherein 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, it is necessary to adjust the length of the slide groove mouth 511 according to the distance between the workpiece 14 and the ring 141 to ensure that when the first telescoping device 12 is fully extended, the C-shaped frame 51 can fix the strip shaft 152 and the round shaft 74.

[0047] Example 2, reference Figure 1-Figure 11 , which is the first embodiment of the present invention, provides a motorcycle shock absorber with an auxiliary shock absorbing mechanism, including a casing 16. The workpiece 14 is placed inside the casing 16 when in use. An interface block 17 is provided at one end of the workpiece 14. A shock absorbing spring 18 is connected between the interface block 17 and the casing 16. A cooling member 19 is provided outside the casing 16. The cooling member 19 can cool the casing 16, thereby ensuring the shock absorbing effect and preventing the workpiece 14 and the casing 16 from overheating.

[0048] The working principle of the present invention is as follows: a plurality of workpieces 14 are placed inside the placement box 11, at which time the lowest workpiece 14 will fall above the square rod 91, and one end of the workpiece 14 will enter the inside of the square rod 91, and then the first telescopic device 12 is started to pull the inner arc push block 92, so that the inner arc push block 92 and the square rod 91 move synchronously in the direction close to the C-shaped frame 51, and the workpiece 14 located inside the square rod 91 also moves synchronously therewith. When the workpiece 14 moves synchronously with the square rod 91 and the inner arc push block 92, the workpiece 14 and the workpiece 14 outside it will enter the inside of the limiting sleeve 8, and the collar 141 will fit with the arc surface 81 inside the limiting sleeve 8, and the workpiece 14 will be restricted by the limiting sleeve 8 to prevent the workpiece 14 from moving horizontally. When the workpiece 14 is moved, an offset is generated, and as the workpiece 14 is continuously pushed by the push rod 9, one end of the workpiece 14 contacts the inside of the C-shaped frame 51, and the collar 141 squeezes the fillet surface 711 of the arc sleeve 71, so that the arc sleeve 71 moves vertically, and the arc sleeve 71 drives the strip plate 72, the round shaft 74 and the reinforcement rod 15 to move synchronously. At the same time, the arc sleeve 71 compresses the second spring 73 when it moves. Since one end of the workpiece 14 contacts the C-shaped frame 51, the workpiece 14 squeezes the C-shaped frame 51 when it moves, so that the C-shaped frame 51 drives the sliding shaft block 52 to move, and the C-shaped frame 51 compresses the first spring 53. At this time, when the C-shaped frame 51 moves, the relative positions of the sliding groove 511, the reinforcement rod 15 and the round shaft 74 The workpiece 14 is also changed, and as the workpiece 14 continues to move, 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 squeezing of the workpiece 14 on the C-shaped frame 51, the reinforcement rod 15 and the round shaft 74 will first contact the end point of the slide groove 511, and then the C-shaped frame 51 will continue to move a short distance. Therefore, the C-shaped frame 51 squeezes the reinforcement rod 15 and the round shaft 74 to fix them together. At this time, the first telescopic device 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, and can only rotate. At this time, welding The device 2 drives the welding head 21 to the welding 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 limit member 7 also rotates as a whole. At this time, the limit member 7 will also drive the collar 141 and the workpiece 14 to rotate, so that the weld is completely welded. Then the first telescopic device 12 contracts, and the square rod 91 and the inner arc push block 92 move back. However, since the inner arc push block 92 is smooth inside and the friction is low, and 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 at this time to cause the workpiece 14 to move back.The collar 141 is free from the restriction of the arc sleeve 71, but the C-shaped frame 51 is quickly moved back under the influence of the first spring 53, which impacts the workpiece 14, so that the workpiece 14 completely enters the interior of the limit sleeve 8, and then the second telescopic device 13 is used to push the limit sleeve 8 to move, and the limit sleeve 8 will drive the welded workpiece 14 to move, and there is no obstruction below the limit sleeve 8. When the workpiece 14 is no longer supported, the workpiece 14 will slide above the inclined plate 10, and then slide above the conveyor 4, and the welded workpiece 14 will be conveyed by the conveyor 4. Then the second telescopic device 13 pulls the limit sleeve 8 back, and the square rod 91 pushes the next workpiece 14 to be welded.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
