Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically to a multi-size adaptable shock absorber end cap welding equipment. Background Technology

[0002] Shock absorbers are indispensable components in vehicles such as cars and motorcycles, as well as many industrial equipment. They can effectively reduce vibrations caused by uneven road surfaces or equipment operation, thereby improving ride comfort and equipment stability.

[0003] Chinese utility model patent CN118905489A discloses a welding equipment for the production of automotive shock absorbers, which aims to solve the problems of unsatisfactory centering effect, swaying during welding, and difficulty in adapting to products with different sleeve heights in the existing technology.

[0004] However, although the device can fix sleeves of different heights, it is difficult to fix shock absorber sleeves of different diameters. It is necessary to constantly change the clamps to fix the sleeves. In addition, the existing technology generally uses the pressing method to fix the end cap when welding the end cap, which will cause some wear to the protruding end of the end cap.

[0005] Based on this, this utility model designs a multi-size adaptable shock absorber end cap welding equipment to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a multi-size adaptable shock absorber end cap welding equipment.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A multi-size adaptable shock absorber end cap welding device, including a base;

[0009] The top of the base is fixedly installed with a surrounding plate to prevent cooling water from splashing out. A side plate is fixedly connected to the rear side of the surrounding plate. Two welding devices for welding the shock absorber end caps are symmetrically installed on the top of the front side of the side plate.

[0010] An end cap pressing assembly is installed on the front side of the side plate, between the two welding devices.

[0011] An adjustable inner support assembly for bearing the end cap and shock absorber cylinder and assisting in welding is installed at the top center of the base. The adjustable inner support assembly includes a translation component, an inner support component, and a rotation drive component. The translation component is connected to the base, and the translation component is connected to both the inner support component and the rotation drive component. The inner support component and the rotation drive component are also connected.

[0012] Furthermore, the end cap pressing assembly includes a movable module, a mounting plate, an extrusion block, and ball bearings. The movable module is fixedly installed in the middle of the side plate and located between the two welding devices. The output end of the movable module is fixedly connected to the mounting plate. A cylindrical extrusion block is fixedly connected to the bottom front end of the mounting plate. The bottom end of the extrusion block is set as an arc surface, and multiple ball bearings are rotatably installed on the surface of the arc surface.

[0013] Furthermore, the translation component includes an electric push rod, a waterproof box, sliders, and slide rails. The electric push rod is fixedly installed on the rear side of the side plate. The output end of the electric push rod slides through the rear side plate of the side plate and the enclosure and is fixedly connected to the waterproof box. Sliders are fixedly connected to both sides of the bottom of the waterproof box. Two slide rails that slide and cooperate with the two sliders are fixedly installed on the top of the base.

[0014] Furthermore, the internal support assembly includes a cylinder, a sliding rod, a push plate, a rotating rod, an arc-shaped abutment block, a sleeve rod, and a placement plate. The cylinder is fixedly installed on the inner bottom wall of the waterproof box. The output end of the cylinder is rotatably connected to the sliding rod via a bearing. The top of the sliding rod slides through the top of the waterproof box and extends to the outside. A sleeve rod is slidably fitted on the outer side of the top of the sliding rod. A placement plate for placing the shock absorber sleeve is fixedly connected to the bottom end of the sleeve rod. A push plate is fixedly connected to the top of the sliding rod. Multiple rotating rods are hinged to the outside of the push plate and the sleeve rod. The other end of the multiple rotating rods is hinged to an arc-shaped abutment block for abutting against the inner wall of the shock absorber.

[0015] Furthermore, the rotation drive assembly includes a drive motor, a sprocket assembly, a hollow column, a sliding block, a keyway, and a carrier box. The carrier box is fixedly installed on the bottom wall inside the waterproof box. The drive motor is fixedly installed on the top of the carrier box. The output end of the drive motor is fixedly connected to the sprocket assembly, which consists of two sprockets and a chain. The two sprockets are connected by chain drive. The output end of the drive motor and the hollow column are fixedly connected to the two sprockets respectively. A keyway is provided inside the hollow column, and a sliding block is slidably engaged in the keyway.

[0016] Furthermore, the top of the hollow column extends through the waterproof box to the outside, and the hollow column is rotatably connected to the top of the waterproof box via a bearing, while the top of the hollow column is fixedly connected to the bottom surface of the placement plate.

[0017] Furthermore, the top of the sliding rod rotates through the interior of the hollow column, and the outer wall of the sliding rod is fixedly connected to the sliding block.

[0018] Compared with the prior art, the advantages of this utility model are as follows:

[0019] 1. In this utility model, the extrusion block is moved towards the end cap by the moving module until the ball bearing on the bottom arc surface of the extrusion block is in close contact with the convex surface of the end cap. This can reduce the friction between the end cap and the extrusion block when the end cap rotates. At the same time, the ball bearing can adapt to end caps with different arc shapes.

[0020] 2. In this utility model, as the cylinder extends, multiple rotating rods are pushed upward by the sliding rod. Under the push of this force, the arc-shaped abutment block moves closer to the inner wall of the shock absorber sleeve and fits tightly against it, thus achieving the fixation of shock absorber sleeves of different diameters.

[0021] 3. In this utility model, the drive motor can drive the hollow column to rotate through the sprocket assembly. The hollow column can drive the placement plate to rotate. Since the arc-shaped abutment block is in close contact with the inner wall of the shock absorber sleeve, the shock absorber sleeve and end cap can rotate at the same time as the placement plate rotates, thereby speeding up the welding efficiency. Moreover, while the hollow column is rotating, it can drive the sliding rod to rotate synchronously through the sliding block and keyway, ensuring that there will be no rotational jamming between the push plate, the rotating rod and the arc-shaped abutment block.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0035] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0036] Example 1: In some examples, please refer to the appendix to the specification. Figure 1-9 A multi-size adaptable shock absorber end cap welding equipment includes a base 1, a welding device 4, an end cap pressing assembly 5, and an adjustable inner support assembly 6; a surrounding plate 2 to prevent cooling water from splashing is fixedly installed on the top of the base 1, a side plate 3 is fixedly connected to the rear side of the surrounding plate 2, and two welding devices 4 for welding shock absorber end caps are symmetrically installed on the top of the front side of the side plate 3; the end cap pressing assembly 5 is installed on the front side of the side plate 3 and at the position between the two welding devices 4.

[0037] An adjustable inner support assembly 6 is installed at the top center of the base 1 for bearing the end cap and shock absorber cylinder and assisting in welding. The adjustable inner support assembly 6 includes a translation assembly 61, an inner support assembly 62 and a rotation drive assembly 63. The translation assembly 61 is connected to the base 1, and the translation assembly 61 is connected to both the inner support assembly 62 and the rotation drive assembly 63. The inner support assembly 62 and the rotation drive assembly 63 are also connected.

[0038] When using this utility model, such as Figures 1-4 The position of the shock absorber sleeve and its end cap can be adjusted by the translation component 61, making it easy for manual handling. The welding device 4 can weld the shock absorber sleeve and end cap, and can spray water to cool them down during welding. The end cap pressing component 5 can press the end cap tightly to prevent it from falling off during welding. The inner support component 62 can support and fix shock absorber sleeves of different diameters. The rotation drive component 63 can rotate the shock absorber sleeve to speed up the welding efficiency.

[0039] In some embodiments, such as Figure 4 The welding device 4 consists of a mounting box 41, a drive shaft 43, a translation device 42, a welding plate 44, and a nozzle 45. The drive shaft 43 is rotatably mounted in the middle of the mounting box 41, and the welding plate 44 is fixedly mounted at the bottom end of the drive shaft 43. The translation device 42 is installed between the back side of the mounting box 41 and the top of the front side of the side plate 3. The nozzle 45 is installed on the side of the mounting box 41 near the end cover. The translation device 42 can drive the two welding plates 44 to move towards the end cover synchronously for welding. The welding plates 44 are welded to the end cover by resistance welding. The drive shaft 43 is used to drive the welding plates 44 to rotate for welding the end cover. The nozzle 45 is connected to an external water supply device through a water pipe, which can quickly cool down the end cover during welding. A motor is fixedly connected to the top of the mounting box 41 via a bracket. The output end of the motor is fixedly connected to the top of the drive shaft 43. The translation device 42 includes a cylinder and a slide rail. A cylinder is fixedly connected to the rear end of the side plate 3. The output end of the cylinder is fixedly connected to the mounting box 41 via a bracket. A slide rail is fixedly connected to the top of the front side of the side plate 3. The mounting box 41 is slidably connected to the slide rail via a slider.

[0040] When this utility model is in use, the cylinder drives the mounting box 41 to move synchronously towards the end cover along the slide rail. The mounting box 41 synchronously drives the welding plate 44 to move. At the same time, the output end of the motor drives the welding plate 44 to rotate through the drive shaft 43 to perform welding.

[0041] In some embodiments, the end cap pressing assembly 5 includes a movable module 51, a mounting plate 52, an extrusion block 53, and ball bearings 55. The movable module 51 is fixedly installed in the middle of the front side of the side plate 3 and located between the two welding devices 4. The output end of the movable module 51 is fixedly connected to the mounting plate 52. The bottom front end of the mounting plate 52 is fixedly connected to a cylindrical extrusion block 53. The bottom end of the extrusion block 53 is set as an arc surface 54, and a plurality of ball bearings 55 are rotatably mounted on the concave surface of the arc surface 54.

[0042] When using this utility model, such as Figures 8-9 The moving module 51 drives the extrusion block 53 to move toward the end cap until the ball 55 on the bottom arc surface 54 of the extrusion block 53 is in close contact with the convex surface of the end cap. This reduces the friction between the end cap and the extrusion block 53 when the end cap rotates. The ball 55 is protruding and mounted on the arc surface 54, which can prevent the convex surface of the end cap from contacting the concave surface of the arc surface 54. In this way, the ball 55 can adapt to end caps with different arc surface shapes.

[0043] In some embodiments, the translation component 61 includes an electric push rod 611, a waterproof box 612, a slider 613, and a slide rail 614. The electric push rod 611 is fixedly installed on the rear side of the side plate 3. The output end of the electric push rod 611 slides through the rear side plate of the side plate 3 and the rear side plate of the enclosure 2 and is fixedly connected to the waterproof box 612. Slider 613 is fixedly connected to both sides of the bottom of the waterproof box 612. Two slide rails 614 that slide and cooperate with the two sliders 613 are fixedly installed on the top of the base 1.

[0044] When using this utility model, such as Figure 6 The electric push rod 611 extends and retracts, and the waterproof box 612 moves along the direction of the slide rail 614 under the restriction of the slider 613 and the slide rail 614, so that workers can pick up and put away the welded shock absorber sleeve. The waterproof box 612 can prevent the cooling water from affecting the drive motor 631 and the cylinder 621.

[0045] In some embodiments, the inner support assembly 62 includes a cylinder 621, a sliding rod 622, a pusher plate 623, a rotating rod 624, an arc-shaped abutment block 625, a sleeve rod 626, and a placement plate 627. The cylinder 621 is fixedly installed on the inner bottom wall of the waterproof box 612. The output end of the cylinder 621 is rotatably connected to the sliding rod 622 via a bearing. The top of the sliding rod 622 slides through the top of the waterproof box 612 and extends to the outside. The sleeve rod 626 is slidably sleeved on the outer side of the top of the sliding rod 622. The bottom end of the sleeve rod 626 is fixedly connected to the placement plate 627 for placing the shock absorber sleeve. The top of the sliding rod 622 is fixedly connected to the pusher plate 623. Multiple rotating rods 624 are hinged to the outside of both the pusher plate 623 and the sleeve rod 626. The other end of the multiple rotating rods 624 is hinged to an arc-shaped abutment block 625 for abutting against the inner wall of the shock absorber.

[0046] When using this utility model, such as Figures 6-7 When fixing shock absorber sleeves of different sizes, the cylinder 621 first retracts, at which point the sliding rod 622 moves downward. While moving downward, multiple rotating rods 624 are pulled downward by the sliding rod 622. Under the action of this force, the arc-shaped abutment block 625 is forced to retract towards the sliding rod 622. Only then is there enough space to place the shock absorber sleeve on top of the placement plate 627. At this time, the arc-shaped abutment block 625 is located inside the shock absorber sleeve. Then, the cylinder 621 extends. While the cylinder 621 extends, multiple rotating rods 624 are pushed upward by the sliding rod 622. Under the push of this force, the arc-shaped abutment block 625 moves closer to and fits tightly against the inner wall of the shock absorber sleeve, thus achieving the fixing of shock absorber sleeves of different diameters.

[0047] In some embodiments, the rotation drive assembly 63 includes a drive motor 631, a sprocket set 632, a hollow column 633, a sliding block 634, a keyway 635, and a carrier box 636. The carrier box 636 is fixedly installed on the bottom wall inside the waterproof box 612. The drive motor 631 is fixedly installed on the top of the carrier box 636. The output end of the drive motor 631 is fixedly connected to the sprocket set 632. The sprocket set 632 consists of two sprockets and a chain. The two sprockets are connected by chain drive. The output end of the drive motor 631 and the hollow column 633 are fixedly connected to the two sprockets respectively. A keyway 635 is provided inside the hollow column 633. The sliding block 634 is slidably engaged in the keyway 635.

[0048] The top of the hollow column 633 extends through the waterproof box 612 to the outside, and the hollow column 633 is rotatably connected to the top of the waterproof box 612 via a bearing. The top of the hollow column 633 is fixedly connected to the bottom surface of the placement plate 627. The top of the sliding rod 622 rotatably passes through the interior of the hollow column 633, and the outer wall of the sliding rod 622 is fixedly connected to the sliding block 634.

[0049] When using this utility model, such as Figures 4-5 While the welding device 4 is welding the shock absorber sleeve and end cap, the drive motor 631 can drive the hollow column 633 to rotate through the sprocket group 632. The hollow column 633 can drive the placement plate 627 to rotate. Since the arc-shaped abutment block 625 is in close contact with the inner wall of the shock absorber sleeve, the placement plate 627 can drive the shock absorber sleeve and end cap to rotate at the same time, thereby speeding up the welding efficiency. While the hollow column 633 is rotating, it can drive the sliding rod 622 to rotate synchronously through the sliding block 634 and the keyway 635, ensuring that there will be no rotation jamming between the push plate 623, the rotating rod 624 and the arc-shaped abutment block 625.

[0050] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
