Description
Technical Field
[0001] This utility model relates to the field of automotive shock absorber technology, specifically to a shock absorber outer cylinder rotary welding device. Background Technology
[0002] Automotive shock absorbers are key components of a vehicle's suspension system, primarily used to reduce vibrations caused by uneven road surfaces, thereby improving ride comfort and handling stability. They are mainly classified into hydraulic shock absorbers, pressure-driven shock absorbers, and electronic shock absorbers. Existing shock absorber structures mainly consist of components such as piston rods, pistons, hydraulic fluid, cylinders, and springs.
[0003] The outer cylinder of the shock absorber is generally fixed by circumferential welding. Current technology mostly involves manual or welding robot circumferential welding along the butt joint. During the welding process, the shock absorber is generally fixed in a vertical position. However, during the welding process, the vertical position of the shock absorber will cause the welding liquid to flow along the outer wall of the outer cylinder, which can easily form pores, resulting in poor welding sealing and welding defects. This leads to unstable welding performance of the outer cylinder and affects the final welding effect. Utility Model Content
[0004] This utility model provides a rotary welding device for the outer cylinder of a shock absorber. The shock absorber is set in an inclined manner, which can prevent the welding liquid from flowing along the outer wall of the outer cylinder during the rotary welding of the shock absorber, prevent the formation of pores at the weld, thereby avoiding adverse effects on the welding seal and improving the stability of the outer cylinder welding.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A shock absorber outer cylinder rotary welding device includes a base and a welding mechanism mounted on the base, and further includes:
[0007] A rotating fixture is inclined from the top of the base toward the welding end of the welding mechanism. The rotating fixture includes an inclined placement plate, a bottom clamping assembly rotatably disposed on the side wall of the placement plate, and a drive source for driving the bottom clamping assembly to rotate.
[0008] Preferably, the rotating fixture further includes a mounting base for mounting the placement plate, the mounting base including a base plate and at least two columns vertically disposed on the top of the base plate at different heights.

[0011] Preferably, the drive source is a servo motor, which is connected to a fixed base via a coupling.
[0012] Preferably, the rotating fixture further includes a top clamping assembly disposed on the top sidewall of the placement plate.
[0013] Preferably, the top clamping assembly includes a connecting plate disposed on the top side wall of the placement plate, a top clamping cylinder fixed to the side wall of the connecting plate, and a top gripper disposed on the moving end of the top clamping cylinder.
[0014] Preferably, the connecting plate is slidably mounted on the side wall of the placement plate via a guide rail.
[0015] Preferably, the shock absorber outer cylinder rotary welding device further includes a protective cover disposed around the base, and the front of the protective cover is provided with a roller shutter door.

[0028] A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings.
[0029] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions: (Refer to...) Figure 1 A shock absorber outer cylinder rotary welding device includes a base 10 and a welding mechanism 20 disposed on the base, and a rotary fixture 30. Further, the rotary fixture is inclined from the top of the base towards the welding end of the welding mechanism 20, and includes a placement plate 310, a bottom clamping assembly 320, and a drive source 330. The placement plate 310 is inclinedly positioned on the top of the base 10, the bottom clamping assembly is rotatably disposed on the side wall of the placement plate, and the drive source 330 is disposed at the bottom of the placement plate and is used to drive the bottom clamping assembly to rotate. In use, the shock absorber to be welded is mounted on the placement plate and fixed and limited by the bottom clamping assembly. After the shock absorber is clamped, it can be driven by the drive source to rotate in an inclined manner, thereby allowing the welding mechanism to weld the shock absorber. Since the shock absorber in this invention is inclined, the welding liquid can be prevented from flowing along the outer wall of the outer cylinder during the rotary welding of the shock absorber, preventing the formation of pores at the weld, thus avoiding adverse effects on the welding seal and improving the stability of the outer cylinder welding.
[0030] Reference Figure 2Furthermore, the welding mechanism includes a welding machine 210, a welding robot 220, a welding machine transformer 230, and a robot control cabinet 240. The welding machine transformer is electrically connected to the welding machine and is used to convert high-voltage, low-current AC power into low-voltage, high-current AC power for welding. The robot control cabinet is used to control the operation of the welding robot.
[0031] Reference Figure 3 As a preferred technical solution in this embodiment, the rotating fixture further includes a mounting base 340 for mounting the placement plate 310. The mounting base 340 includes a base plate 341 and columns 342. The number of columns is at least two. In this embodiment, there are two columns 342, and the two columns are of different heights. The two columns are vertically fixed on the top of the base plate. In this way, when the placement plate is placed on the top surface of the two columns, an inclined structure can be formed, thereby using the inclined structure to place the shock absorber.
[0032] Reference Figure 3 Furthermore, the bottom clamping assembly 320 includes a fixed base 321, a bottom clamping plate 322, a bottom clamping cylinder 323, and bottom grippers 324. The fixed base 321 is fixedly mounted on the side wall of the placement plate 310. The bottom clamping plate 322 is rotatably mounted on the fixed base. The bottom clamping cylinder 323 is mounted on the clamping end of the bottom clamping plate. The bottom grippers 324 are mounted on the moving end of the bottom clamping cylinder. It should be noted that there are two bottom grippers arranged opposite each other, and the two bottom grippers can be opened and closed by the bottom clamping cylinder. In this way, when the two bottom grippers are closed, the bottom position of the shock absorber is clamped and fixed, so that when the bottom clamping plate is driven to rotate by the drive source, the shock absorber can be tilted and rotated.
[0033] In addition, in order to sense the position of the shock absorber when it rotates, a position sensor 311 for detecting the state of the bottom gripper 324 is provided on the side wall of the placement plate 310. Since the shock absorber rotates with the bottom gripper, the rotation position of the shock absorber can be detected by detecting the position of the bottom gripper.
[0034] Furthermore, the drive source 330 is a servo motor, which is connected to the fixed base 321 through a coupling. In this way, the power of the drive source is transmitted to the bottom clamping plate 322 through the coupling, thereby driving the bottom clamping plate to rotate, so as to realize the rotation of the outer cylinder of the shock absorber to be welded.
[0035] Reference Figure 3In some embodiments, in order to effectively clamp and fix the outer cylinder of the shock absorber, the rotating tooling 30 further includes a top clamping assembly 350 disposed on the top side wall of the placement plate 310. Further, the top clamping assembly includes a connecting plate 351, a top clamping cylinder 352, and top jaws 353. The connecting plate 351 is disposed on the top side wall of the placement plate 310, the top clamping cylinder 352 is fixedly disposed on the side wall of the connecting plate, and the top jaws 353 are disposed at the moving end of the top clamping cylinder. It should be noted that there are two top jaws arranged opposite each other, and these two top jaws can be opened and closed by the top clamping cylinder. In use, the top end of the outer cylinder of the shock absorber is located between the top jaws. The top clamping cylinder can drive the two top jaws to clamp and fix the outer cylinder of the shock absorber. This, combined with the bottom clamping assembly, clamps and fixes the shock absorber from both the top and bottom, thereby improving the fixing effect of the shock absorber.
[0036] Furthermore, as the bottom of the shock absorber rotates with the bottom clamping plate, the top of the shock absorber rotates relative to the top clamping jaws; that is, the top clamping jaws are fixed, while the top of the shock absorber is movable.
[0037] Furthermore, in order to facilitate the adjustment of the vertical height of the top clamping assembly along the placement plate, the connecting plate 351 is slidably disposed on the side wall of the placement plate 310 via a guide rail. Specifically, in this embodiment, a guide rail can be provided on the side wall of the placement plate, and correspondingly, a slider is provided on the side wall of the connecting plate. At the same time, the slider is slidably connected to the guide rail, so that the sliding connection between the connecting plate and the placement plate can be achieved by utilizing the sliding contact between the slider and the guide rail.
[0038] Reference Figure 4 , Figure 5 , Figure 6 , Figure 7 In some embodiments, the shock absorber outer cylinder rotary welding device further includes a protective cover 40 disposed around the base 10. A roller shutter door 410 is provided on the front of the protective cover 40, and a three-color light strip 411 is provided on the side wall of the protective cover above the roller shutter door for warning purposes. At the same time, a touch screen 420 and operation buttons 430 are also provided on the side wall of the protective cover 40 for controlling the welding process. In addition, a right-side single door 440 is provided on the right side of the protective cover, and a robot arm teaching pendant observation window 441 is provided on the right-side single door. A left-side single door 450 is provided on the left side of the protective cover, and a welding observation window 451 is provided on the side wall of the protective cover near the left-side single door. A rear single door 460 is provided on the back of the protective cover, and a welding parameter observation window 470 is provided on the rear side wall of the protective cover.
[0039] In use, the shock absorber to be welded is installed on the placement plate 310 and fixed and limited by the bottom clamping assembly. After the shock absorber is clamped, it can be driven by the drive source 330 to rotate in an inclined manner, so that the shock absorber can be welded by the welding mechanism. In addition, the shock absorber can also be fixed and limited from the top of the shock absorber by the top clamping assembly, so as to achieve the effect of fixing the outer cylinder of the shock absorber from multiple points. Since the shock absorber in this utility model is set in an inclined manner, the welding liquid can be prevented from flowing along the outer wall of the outer cylinder during the rotation welding of the shock absorber, preventing the formation of pores at the weld, thereby avoiding adverse effects on the welding seal and improving the stability of the outer cylinder welding.
