Description

Technical Field

[0002] The shock absorber of an electric bicycle is a crucial component for ensuring a smooth ride. It primarily uses springs and shock absorbers to reduce vibrations caused by road bumps. The shock absorber's operating principle is that when an electric bicycle travels on uneven surfaces, the wheel bounces upward when it encounters a bump. The spring is compressed to absorb the impact, while the shock absorber, through internal hydraulic or pneumatic devices, converts the spring's elastic potential energy into heat and dissipates it, thereby controlling the spring's rebound speed and maintaining relative stability. During the shock absorber manufacturing process, the connections between the various components must be more stable, and welding is one method for achieving this stability.

[0003] There are many existing welding methods. Spot welding is usually used to connect the shock absorber cylinder and the connecting ring. The shock absorber cylinder and the connecting ring are manually placed on corresponding fixtures to align the cylinder and the connecting ring. Then, they are welded together using a welding head to complete the welding of the cylinder and the connecting ring. However, during the welding process, workers need to reposition the connecting ring and the cylinder separately for each welding operation, which is cumbersome and increases the workload of workers while reducing welding efficiency. In addition, when placing the connecting ring, workers need to first put the connecting ring on the positioning pin so that the connecting ring can be in the designated welding position at the top of the cylinder to ensure the quality of the welding. After the welding is completed, workers need to manually remove the connecting ring and the cylinder as a whole from the positioning pin, making the installation and removal of the connecting ring very troublesome.

DETAILED DESCRIPTION

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0022] Example 1, with reference to Figure 1-Figure 4 , which is the first embodiment of the present invention, provides a welding device for shock absorber processing, including a base 1, an L-shaped fixing frame 11 installed on the top of the base 1, a cylinder 15 installed on one side of the L-shaped fixing frame 11, and a welding head 12 installed on the top of the L-shaped fixing frame 11, and also includes a welding unit installed on the base 1; the welding unit includes a distribution component installed on the base 1, and an insertion component installed on one side of the distribution component, the distribution component includes a lifting assembly 2 installed on the base 1, and a driving assembly 3 arranged on one side of the lifting assembly 2; the lifting assembly 2 includes a support plate 21 fixedly connected to the top of the base 1, a first hydraulic cylinder 23 is fixedly connected to the top of the support plate 21, a placement cylinder 22 is fixedly connected to the output end of the first hydraulic cylinder 23, and a plurality of connecting rings 24 are evenly placed inside the placement cylinder 22.

[0023] Specifically, during operation, the cylinder 15 is placed on one side of the L-shaped fixing frame 11, and several connecting rings 24 are placed in the placement cylinder 22. The cylinder 15 and the connecting ring 24 are welded by the welding head 12. The several connecting rings 24 are welded one by one by the welding unit, and there is no need to manually place the connecting rings 24 one by one on the bottom of the placement cylinder 22. The several connecting rings 24 in the placement cylinder 22 are distributed one by one by the distribution component, so that the several connecting rings 24 are welded in an orderly manner. The connecting rings 24 are limited and stabilized by the insertion component, so that the connecting rings 24 are welded in an orderly manner. When the connecting ring 24 and the cylinder 15 are welded, their positions will not shift. The distribution component is started to make the lifting assembly 2 work, and the support plate 21 supports the first hydraulic cylinder 23. Under the action of the first hydraulic cylinder 23, the placement cylinder 22 is pushed up and down, so that the connecting ring 24 in the placement cylinder 22 is aligned with the top of the cylinder 15, completing the welding operation and realizing batch welding of shock absorber components. There is no need to manually place the connecting rings 24 one by one on the bottom of the placement cylinder 22, which not only saves labor, but also reduces the probability of defective products and is safer to operate.

[0024] Reference Figure 5-Figure 7 The driving assembly 3 includes a fixed rod 35 fixedly connected to the support plate 21, and a rack 34 is fixedly connected to the fixed rod 35. The bottom of the placement cylinder 22 is slidingly connected to the driving rod 31, and the bottom of the placement cylinder 22 is also rotatably connected to the threaded rod 33. The driving rod 31 is threadedly connected to the outside of the threaded rod 33, and the end of the threaded rod 33 away from the placement cylinder 22 is fixedly connected to a gear 32, and the gear 32 is meshed with the rack 34.

[0025] Specifically, when the placement cylinder 22 moves up and down, it drives the threaded rod 33 and the gear 32 thereon to move up and down. With the cooperation of the rack 34, the gear 32 rolls on the rack 34, driving the threaded rod 33 to rotate, so that the driving rod 31 slides within a limit on the outside of the threaded rod 33, and the driving rod 31 moves back and forth on the placement cylinder 22. When the placement cylinder 22 moves up and down, the driving assembly 3 can be started to work, so that the shock absorber components inside the placement cylinder 22 fall one by one and are welded to the cylinder body 15 on the top of the base 1. The degree of automation is higher, it is not easy to make mistakes, and the safety factor is high.

[0026] Reference Figure 5-Figure 7 and Figure 11The distribution component also includes a distribution component 4 installed on one side of the driving component 3, and a blocking component 5 installed at the bottom of the placement cylinder 22; the distribution component 4 includes two symmetrically distributed distribution plates 44 that are slidably connected to the bottom of the placement cylinder 22, and the two distribution plates 44 are fixedly connected to the moving blocks 43 on the opposite sides thereof, and the two moving blocks 43 are provided with first inclined surfaces on the opposite sides thereof, and the two first inclined surfaces are provided with first T-shaped slides 45, and the inner sides of the two first T-shaped slides 45 are slidably connected with first T-shaped sliders 42, and the two first T-shaped sliders 42 are fixedly connected to the side rods 41 on the side away from the moving block 43, and the end of the side rods 41 away from the first T-shaped sliders 42 is fixedly connected to the driving rod 31.

[0027] Specifically, before welding, several connecting rings 24 are placed in the placement tube 22, and the two distribution plates 44 slide relative to and opposite to each other at the bottom of the placement tube 22, so that the connecting rings 24 in the placement tube 22 fall to the bottom of the placement tube 22 one by one, and then are welded with the cylinder 15 on the top of the base 1. The driving rod 31 moves back and forth on the placement tube 22, driving the side rod 41 to move back and forth, so that the first T-shaped slider 42 slides back and forth inside the first T-shaped slide groove 45. Under the action of the first inclined surface, the moving block 43 is driven to move back and forth, thereby making the two distribution plates 44 slide relative to and opposite to each other in the placement tube 22, so that in the process of the placement tube 22 moving up and down, the connecting rings 24 in the placement tube 22 fall to the bottom of the placement tube 22 one by one, which not only improves the efficiency of welding but also reduces the labor cost.

[0028] Reference Figure 11 The blocking assembly 5 includes two symmetrically distributed first movable chambers 51 opened at the bottom of the placement tube 22. The inner walls of the two first movable chambers 51 at the separated ends are fixedly connected to the first springs 52. The opposite ends of the two first movable chambers 51 are slidably connected to the blocking rods 53. The blocking rods 53 are fixedly connected to the first springs 52, and a second inclined surface is opened at the end of the blocking rod 53 away from the first spring 52.

[0029] Specifically, the connecting ring 24 that falls on the bottom of the placing tube 22 is blocked at the bottom of the placing tube 22 by the action of the two blocking rods 53, so as to prevent the connecting ring 24 from falling out from the bottom of the placing tube 22 and affecting the welding. Under the action of the first spring 52, the two blocking rods 53 have a tendency to move toward the outside of the first movable cavity 51, so that the two blocking rods 53 always stay inside the placing tube 22 to block the connecting ring 24 at the bottom of the placing tube 22. When the connecting ring 24 and the cylinder body 15 are welded, the connecting ring 24 and the cylinder body 15 are rigidly connected, so that the connecting ring 24 will be The first spring 52 is pressed against the first movable cavity 51 so that the blocking rod 53 no longer blocks the connecting ring 24, and the shock absorber components that have been welded can be removed. After removal, the first spring 52 is reset, so that the blocking rod 53 stays in the placement tube 22 again, blocking the connecting ring 24 in the placement tube 22, so that the connecting rings 24 fall one by one in the placement tube 22, and the connecting ring 24 at the bottom of the placement tube 22 is not easy to fall from the bottom of the placement tube 22.

[0030] Example 2, reference Figure 5 、 Figure 6 and Figures 8-10 , which is a second embodiment of the present invention, which is different from the first embodiment in that: the insertion component includes an insertion component 6 installed on one side of the support plate 21, a pushing component 7 installed on one side of the top of the insertion component 6, and a limiting component 8 installed on the other side of the top of the insertion component 6; the insertion component 6 includes a second T-shaped slide 67 provided on the support plate 21, and a second T-shaped slider 64 is slidably connected to the inner side of the second T-shaped slide 67, and a connecting rod 63 is fixedly connected to the second T-shaped slider 64. The connecting rod 63 is fixedly connected to the insertion tube 62, and the insertion tube 62 is slidably connected to the insertion rod 61 at one end away from the connecting rod 63. A return spring 68 is fixedly connected between the insertion rod 61 and the inner wall of the insertion tube 62, and a side pressure block 65 is fixedly connected to the end of the insertion rod 61 away from the insertion tube 62. A notch 69 is provided on one side of the bottom of the placement tube 22, and the notch 69 is adapted to the side pressure block 65. The side pressure block 65 is fixedly connected to an insertion block 66 on the side away from the insertion rod 61, and the insertion block 66 is adapted to the circular hole of the connecting ring 24.

[0031] Specifically, when the connecting ring 24 dropped on the bottom of the placement tube 22 is welded, the insertion block 66 is adapted to the circular hole of the connecting ring 24, and the insertion block 66 is inserted into the circular hole of the connecting ring 24, so that the connecting ring 24 conflicts with the shock absorber component on the top of the base 1, ensuring the strength of the connecting ring 24 and the shock absorber component after welding. When the placement tube 22 moves up and down, the pushing component 7 is triggered, so that the pushing component 7 pushes the insertion component 6 to move, so that the second T-shaped slider 64 slides inside the second T-shaped slide groove 67, driving the connecting rod 63 to move. Drive the insertion tube 62 to move, drive the insertion rod 61 to move, drive the side pressure block 65 to move, so that the insertion block 66 is inserted into the circular hole of the connecting ring 24. At the same time, the side pressure block 65 will move into the notch 69 and press the side of the connecting ring 24 tightly, ensuring that the connecting ring 24 is welded to the cylinder body 15. After welding, the placement tube 22 will move upward, triggering the pushing component 7, so that the pushing component 7 drives the insertion component 6 to move away from the placement tube 22, so that the insertion block 66 is separated from the connecting ring 24, making it convenient to remove the welded shock absorber components from the device.

[0032] Reference Figure 5 、 Figure 6 and Figure 8 The pushing assembly 7 includes a pushing block 72 fixedly connected to the top of the insertion tube 62, a third inclined surface is provided on the top of the pushing block 72, a third T-shaped slide groove 73 is provided on the third inclined surface, a third T-shaped slider 74 is slidably connected to the inner side of the third T-shaped slide groove 73, and the third T-shaped slider 74 is fixedly connected to the side away from the pushing block 72 with an L-shaped rod 71, and the end of the L-shaped rod 71 away from the third T-shaped slider 74 is fixedly connected to the placement tube 22.

[0033] Specifically, when the placement tube 22 moves up and down, it will trigger the pushing assembly 7, driving the L-shaped rod 71 to move, so that the third T-shaped slider 74 slides inside the third T-shaped slide groove 73. Under the action of the third inclined surface, the pushing block 72 moves horizontally, driving the insertion tube 62 to move. After welding is completed, the placement tube 22 moves upward, driving the L-shaped rod 71 to move upward, so that the bottom of the L-shaped rod 71 slides upward on the third inclined surface, driving the insertion tube 62 to move away from the placement tube 22.

[0034] Reference Figure 5 、 Figure 6 、 Figure 8 and Figure 9The limit assembly 8 includes a limit cylinder 81 fixedly connected to the L-shaped rod 71, and the bottom of the limit cylinder 81 is slidably connected to the limit rod 84. A second spring 82 is fixedly connected between the limit rod 84 and the inner wall of the limit cylinder 81. The top of the insertion rod 61 is fixedly connected to the limit block 85 near the side pressure block 65. The top of the limit block 85 is provided with a limit groove 86 that is compatible with the limit rod 84. The bottom of the push block 72 is fixedly connected to the side of the limit rod 84 near the limit rod 84. The top side of the limit block 85 is provided with an ejection rod 83 that is compatible with the ejection rod 83. The opposite ends of the limit rod 84 and the ejection rod 83 are both provided with a hemispherical structure.

[0035] Specifically, the function of the limit assembly 8 is that the insertion assembly 6 can be inserted into the circular hole of the connecting ring 24 instantly, so that the insertion block 66 has not been inserted into the circular hole of the connecting ring 24, and the connecting ring 24 continues to move downward, resulting in the insertion block 66 cannot be inserted into the circular hole of the connecting ring 24. When the placement cylinder 22 moves downward, it drives the L-shaped rod 71 to move, drives the limit cylinder 81 to move downward, drives the limit rod 84 to move downward, so that the bottom of the limit rod 84 is inserted into the limit groove 86, and limits the limit block 85. At this time, the placement cylinder 22 will continue to move downward, drive the L-shaped rod 71 to continue to move downward, drive the limit cylinder 81 to move downward, and at this time the limit rod 84 is clamped in the limit groove 86, so the limit rod 84 will move into the limit cylinder 81, squeeze the second spring 82, and the limit block 85 is limited, which is conducive to the insertion rod 6 1 is limited, the insertion tube 62 will continue to move, so that the insertion tube 62 slides outside the insertion rod 61, squeezing the return spring 68, and the insertion tube 62 will drive the push block 72 to move, thereby driving the ejection rod 83 to move. During the movement, the ejection rod 83 will be inserted into the ejection groove 87. Since the opposite ends of the limit rod 84 and the ejection rod 83 are both configured with a hemispherical structure, the ejection rod 83 will push the limit rod 84 to move outside the limit groove 86. When the ejection rod 83 is fully inserted into the ejection groove 87, the limit rod 84 is ejected out of the limit groove 86. At this time, the return spring 68 will reset, so that the insertion rod 61 will move outside the insertion tube 62, driving the side pressure block 65 and the insertion block 66 to move toward the side of the placement tube 22, so that the insertion block 66 is instantly inserted into the connecting ring 24, completing the limiting of the connecting ring 24. The rest of the structure is the same as that of Example 1.

This embodiment is different from the second embodiment in that it also includes a clamping assembly 9, the clamping assembly 9 includes a mounting plate 91 fixedly connected to one side of the base 1, a second hydraulic cylinder 92 is fixedly connected to the top of the mounting plate 91, the output end of the second hydraulic cylinder 92 passes through the mounting plate 91 and is fixedly connected to an L-shaped movable frame 94, a sliding groove 93 is opened on the top of the base 1, a sliding block 95 is slidably connected to the inner side of the sliding groove 93, and the sliding block 95 is fixedly connected to the L-shaped movable frame 94.

[0037] Specifically, the clamping assembly 9 clamps the shock absorber components on the top of the base 1, and the second hydraulic cylinder 92 is supported by the mounting plate 91. The second hydraulic cylinder 92 pushes the L-shaped movable frame 94 to slide on the top of the base 1, causing the sliding block 95 to slide inside the sliding groove 93, making the L-shaped movable frame 94 move more stably. In conjunction with the L-shaped fixed frame 11, the shock absorber components are clamped. The remaining structure is the same as that of Example 2.

[0039] Specifically, the cylinder 15 is placed on the top of the base 1 and clamped by the clamping assembly 9. With the cooperation of the L-shaped movable frame 94 and the L-shaped fixed frame 11, the cylinder 15 is clamped. During welding, the placement cylinder 22 will move downward, driving the connecting ring 24 to move downward, so that the bottom of the connecting ring 24 contacts the top of the cylinder 15, and then the cylinder 15 and the connecting ring 24 are welded together through the welding head 12.

[0040] Based on Examples 1-4, the working principle of the present invention is as follows: when welding, the cylinder 15 is placed on the top of the base 1, the cylinder 15 is clamped by the clamping assembly 9, and several connecting rings 24 are placed in the placement cylinder 22. The placement cylinder 22 is driven to move by the lifting assembly 2. During the movement of the placement cylinder 22, the threaded rod 33 and the gear 32 thereon are driven to move up and down. Under the cooperation of the rack 34, the gear 32 rolls on the rack 34, driving the threaded rod 33 to rotate, so that the driving rod 3 The drive rod 31 is limited and slides outside the threaded rod 33, so that the drive rod 31 reciprocates on the placement cylinder 22, driving the side rod 41 to reciprocate, causing the first T-shaped slider 42 to reciprocate inside the first T-shaped slot 45. Under the action of the first inclined surface, the moving block 43 is driven to reciprocate, thereby causing the two distribution plates 44 to slide relative to and away from each other in the placement cylinder 22, so that the connecting rings 24 in the placement cylinder 22 fall one by one to the bottom of the placement cylinder 22, so that the connecting rings 24 contact the top of the cylinder body 15 for welding.
