Description

Technical Field

[0001] The invention relates to the technical field of shock absorber welding, and in particular to a welding device for shock absorber processing and an electric bicycle shock absorber. Background Art

[0002] The shock absorber of an electric bicycle is an important component to ensure the smooth driving of the vehicle. It mainly uses springs and shock absorbers to reduce the vibration caused by road bumps. The working principle of the shock absorber is that when an electric bicycle is driving on an uneven road, the wheel will bounce up when encountering bumps, and the spring will be compressed to absorb the impact force. The shock absorber converts the elastic potential energy of the spring into heat energy through the internal hydraulic or pneumatic device and dissipates it, thereby controlling the rebound speed of the spring and keeping the vehicle body relatively stable. In the processing of the shock absorber, it is necessary to make the connection between the various components of the shock absorber more stable, and welding is a processing method to improve the stability of the connection.

[0003] There are many existing welding methods. In the process of connecting the shock absorber cylinder and the connecting ring, spot welding is usually used for welding. The shock absorber cylinder and the connecting ring are manually placed on the corresponding fixtures to align the cylinder and the connecting ring, and then welded together through the welding head to complete the welding of the cylinder and the connecting ring. However, during the welding process, workers need to re-place the connecting ring and the cylinder for each welding, which is troublesome to operate, increasing the work intensity of the workers and reducing the welding efficiency. In addition, when placing the connecting ring, the workers need to put the connecting ring on the positioning pin first, so that the connecting ring can be in the designated welding position at the top of the cylinder to ensure the quality of welding. After the welding is completed, the workers need to manually remove the connecting ring and the cylinder as a whole from the positioning pin, which makes the installation and removal of the connecting ring very troublesome, and it is impossible to achieve automatic positioning of the connecting ring during welding and quick removal after welding.

[0039] Example 1, reference 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 component 2 installed on the base 1, and a driving component 3 arranged on one side of the lifting component 2; the lifting component 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.

[0040] Specifically, during operation, the cylinder 15 is placed on one side of the L-shaped fixing frame 11, and a plurality of connecting rings 24 are placed in the placement cylinder 22. The cylinder 15 and the connecting rings 24 are welded by the welding head 12. The 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 at the bottom of the placement cylinder 22. The connecting rings 24 in the placement cylinder 22 are distributed one by one by the distribution component, so that the 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 to align the connecting ring 24 in the placement cylinder 22 with the top of the cylinder 15, and the welding operation is completed, thereby realizing batch welding of shock absorber parts. 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.

[0041] Reference Figure 5-Figure 7 The driving assembly 3 includes a fixed rod 35 fixedly connected to the support plate 21, a rack 34 fixedly connected to the fixed rod 35, a driving rod 31 is slidingly connected to the bottom of the placement cylinder 22, and a threaded rod 33 is also rotatably connected to the bottom of the placement cylinder 22. The driving rod 31 is threadedly connected to the outside of the threaded rod 33, and a gear 32 is fixedly connected to the end of the threaded rod 33 away from the placement cylinder 22, and the gear 32 is meshingly connected to the rack 34.

[0042] 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 limited position 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 down one by one and are welded to the cylinder body 15 on the top of the base 1. The degree of automation is stronger, it is not easy to make mistakes, and the safety factor is high.

[0043] Reference Figure 5-Figure 7 and Fig.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 placing cylinder 22; the distribution component 4 includes two symmetrically distributed distribution plates 44 slidably connected to the bottom of the placing cylinder 22, and the two distribution plates 44 are fixedly connected with moving blocks 43 on the opposite sides, and the two moving blocks 43 are provided with first inclined surfaces on the opposite sides, and the two first inclined surfaces are provided with first T-shaped slide grooves 45. The inner sides of the two first T-shaped slide grooves 45 are slidably connected with first T-shaped sliders 42, and the two first T-shaped sliders 42 are fixedly connected with side rods 41 on the side away from the moving blocks 43, and the end of the side rod 41 away from the first T-shaped slider 42 is fixedly connected to the driving rod 31.

[0044] Specifically, before welding, a plurality of connecting rings 24 are placed in the placing tube 22, and two distribution plates 44 are used to slide relative to and away from each other at the bottom of the placing tube 22, so that the connecting rings 24 in the placing tube 22 fall to the bottom of the placing tube 22 one by one, and then are welded to the cylinder 15 on the top of the base 1, and the driving rod 31 is driven to move back and forth on the placing 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, and under the action of the first inclined surface, drives the moving block 43 to move back and forth, thereby making the two distribution plates 44 slide relative to and away from each other in the placing tube 22, so that in the process of the placing tube 22 moving up and down, the connecting rings 24 in the placing tube 22 fall to the bottom of the placing tube 22 one by one, which not only improves the welding efficiency but also reduces the labor cost.

[0045] Reference Fig.11 The blocking assembly 5 includes two first movable chambers 51 symmetrically distributed and 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 with first springs 52. The opposite ends of the two first movable chambers 51 are slidably connected with blocking rods 53. The blocking rod 53 is fixedly connected to the first spring 52, and a second inclined surface is opened at one end of the blocking rod 53 away from the first spring 52.

[0046] 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 to the outside of the first active cavity 51, so that the two blocking rods 53 always stay on the inside of 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 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, so that the welded shock absorber parts can be removed. After removal, the first spring 52 will be reset, so that the blocking rod 53 will stay in the placing tube 22 again, blocking the connecting ring 24 in the placing tube 22, so that the connecting ring 24 can fall one by one in the placing tube 22, and the connecting ring 24 at the bottom of the placing tube 22 is not easy to fall from the bottom of the placing tube 22.

[0047] Example 2, reference Figure 5 , Figure 6 and Figure 8-Figure 10 , 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 groove 67 opened on the support plate 21, a second T-shaped slider 64 is slidably connected to the inner side of the second T-shaped slide groove 67, a connecting rod 63 is fixedly connected to the second T-shaped slider 64, an insertion tube 62 is fixedly connected to the connecting rod 63, an insertion tube 62 is slidably connected to the end of the insertion tube 62 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, 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 opened on one side of the bottom of the placement tube 22, the notch 69 is matched with the side pressure block 65, and an insertion block 66 is fixedly connected to the side of the side pressure block 65 away from the insertion rod 61, and the insertion block 66 is matched with the circular hole of the connecting ring 24.

[0048] Specifically, when the connecting ring 24 dropped on the bottom of the placing tube 22 is welded, the insert block 66 is matched with the circular hole of the connecting ring 24, and the insert 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 placing tube 22 moves up and down, the pushing component 7 is triggered, so that the pushing component 7 pushes the inserting component 6 to move, so that the second T-shaped sliding block 64 slides inside the second T-shaped sliding groove 67, driving the connecting rod 63 to move. The insertion tube 62 is driven to move, the insertion rod 61 is driven to move, and the side pressure block 65 is driven 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 to press against the side of the connecting ring 24, 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.

[0049] 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 an L-shaped rod 71 on the side away from the pushing block 72, 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.

[0050] 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, and under the action of the third inclined plane, 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 plane, driving the insertion tube 62 to move away from the placement tube 22.

[0051] Reference Figure 5 , Figure 6 , Figure 8 and Fig. 9The limiting assembly 8 includes a limiting cylinder 81 fixedly connected to the L-shaped rod 71, a limiting rod 84 is slidably connected to the bottom of the limiting cylinder 81, a second spring 82 is fixedly connected between the limiting rod 84 and the inner wall of the limiting cylinder 81, a limiting block 85 is fixedly connected to the top of the insertion rod 61 near the side pressure block 65, a limiting groove 86 matched with the limiting rod 84 is opened on the top of the limiting block 85, an ejection rod 83 is fixedly connected to the bottom of the push block 72 near the limiting rod 84, an ejection groove 87 matched with the ejection rod 83 is opened on the top of the limiting block 85, and the opposite ends of the limiting rod 84 and the ejection rod 83 are both arranged in a hemispherical structure.

[0052] Specifically, the function of the limiting assembly 8 is that the insertion assembly 6 can be inserted into the circular hole of the connecting ring 24 instantly, so as to avoid 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 tube 22 moves downward, it drives the L-shaped rod 71 to move, drives the limiting tube 81 to move downward, drives the limiting rod 84 to move downward, so that the bottom of the limiting rod 84 is inserted into the limiting groove 86, and the limiting block 85 is limited. At this time, the placement tube 22 will continue to move downward, drive the L-shaped rod 71 to continue to move downward, drive the limiting tube 81 to move downward, and at this time the limiting rod 84 is clamped in the limiting groove 86, so the limiting rod 84 will move into the limiting tube 81, squeeze the second spring 82, and the limiting block 85 is limited, which 1 is limited, the insertion tube 62 will continue to move, so that the insertion tube 62 slides outside the insertion rod 61, compressing the reset spring 68, and the insertion tube 62 will drive the push block 72 to move, and then drive the ejection rod 83 to move. The ejection rod 83 will be inserted into the ejection groove 87 during the movement. Since the opposite ends of the limit rod 84 and the ejection rod 83 are both set to have 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 reset spring 68 will be reset, so that the insertion rod 61 will move to the outside of the insertion tube 62, driving the side pressure block 65 and the insertion block 66 to move to 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.

The rest of the structure is the same as that of Example 2.

[0056] 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.
