Detailed Implementation

[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 , Figure 2A rotary welding device for the outer cylinder of an automotive shock absorber includes a base 10, a welding mechanism, and a rotating mechanism. The welding mechanism is mounted on the base 10 and includes a welding machine 210 and a welding robot 220. The rotating mechanism includes a turntable 310 and welding fixtures 320. The turntable 310 is fixedly mounted on the base 10. Several welding fixtures 320 are evenly distributed on the top of the turntable. Each welding fixture 320 can rotate with the turntable 310 to change the working state of the workpiece fixed thereon. Specifically, in this embodiment, there are two welding fixtures 320, symmetrically arranged radially along the top of the turntable. It should be noted that in this embodiment, the turntable rotates intermittently, allowing the welding fixtures and their components on one side to be rotated during rotation. The shock absorber rotates to the welding station, where a welding robot can weld the outer cylinder of the shock absorber. After the welding of the shock absorber on this side is completed, the turntable can be rotated again to move this part of the shock absorber out, so that the shock absorber on this side of the welding fixture can be moved to the unloading station. At the same time, the welding fixture and the shock absorber on the other side can be moved to the welding station with the turntable. Welding and unloading operations can be performed on the shock absorbers at the welding station and the unloading station respectively. After unloading, the shock absorber to be welded is reassembled. In this way, continuous welding can be achieved while the turntable is rotating. This utility model uses the rotating turntable to change the working state of the workpiece in the welding fixture, so that the welding fixture can switch back and forth between the welding station and the unloading station, which can ensure the continuous welding of the outer cylinder of the shock absorber and improve welding efficiency.

[0030] Reference Figure 2 As a preferred technical solution in this embodiment, the welding mechanism further includes 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] Furthermore, the aforementioned automotive shock absorber outer cylinder rotary welding device also includes a torch cleaner 40, which is mounted on the base 10. During welding, welding slag typically accumulates at the welding torch head, affecting subsequent welding results. The torch cleaner has a shearing mechanism inside that can cut the welding wire with accumulated welding slag, while the oil spraying mechanism can effectively prevent spatter, thereby achieving the cleaning purpose. In this embodiment, the torch cleaner is a dedicated mechanism for the welding robot to clean spatter, cut welding wire, and spray silicone oil, ensuring continuous welding by the welding robot during equipment operation, thereby ensuring the stability and quality of the welding process, and improving production efficiency and product quality.

[0032] Reference Figure 3 , Figure 4In some embodiments, the rotating mechanism further includes a mounting base 330, a motor 340, and a rotating divider 350. The mounting base 330 is fixedly mounted on the base 10 and is used to mount the turntable 310. The motor 340 is fixedly mounted on the mounting base. The rotating divider 350 is located at the output end of the motor and is connected to the turntable to drive the turntable 310 to rotate intermittently. In use, when the motor 340 is working, it transmits power to the rotating divider, which in turn transmits power to the turntable to achieve intermittent rotation of the turntable. It should be noted that the rotating divider in this embodiment is a cam divider, which can realize the intermittent rotation of two welding fixtures. Since the method of achieving 180° intermittent rotation through a cam divider is existing technology, it will not be described in detail here. In this way, while the operator is loading and unloading materials at one station, the welding robot can weld at another station, thereby achieving the purpose of uninterrupted loading and unloading of workpieces and welding, which can improve the working efficiency and production cycle of the equipment.

[0033] Furthermore, refer to Figure 5 In this embodiment, two welding fixtures are symmetrically arranged, and each welding fixture includes a fixture base 321, a fixing cylinder 322, a limiting seat 323, and a fixing column 324. The fixing cylinder 322 is vertically arranged on the fixture base, the limiting seat 323 is fixedly arranged on the top of the fixture base, and the fixing column 324 is arranged at the output end of the fixing cylinder 322. The fixing column 324 passes through the limiting seat 323 and is eccentrically arranged. In use, the bottom end of the shock absorber is located inside the limiting seat, and the fixing column 324 is located below the limiting seat 323. After the shock absorber is placed in place, the fixing cylinder 322 drives the fixing column to move upward. Since the fixing column is eccentrically arranged with the limiting seat and is located near the side of the limiting seat, and the bottom cylinder of the shock absorber has an inwardly tapered structure, when the fixing column moves up to contact the bottom cylinder of the shock absorber, it can fit tightly against the inner wall of the bottom cylinder of the shock absorber to achieve clamping and fixing of the shock absorber.

[0034] It should be noted that the welding fixture 320 in this utility model is not limited to the two mentioned above. That is, there can be more than two welding fixtures 320, such as three, four, etc., as long as the welding fixtures are evenly distributed along the top circumference of the turntable.

[0035] Reference Figure 5 Furthermore, the tooling base 321 includes a base plate 3211, a side plate 3212, and a top plate 3213. There are two side plates, and the two side plates are fixedly fixed to the top of the base plate. The top plate 3213 is fixedly installed on the top of the two side plates. In this way, the base plate, the side plates, and the top plate form a rectangular frame structure, which is used to install and fix the fixed cylinder and the limiting seat.

[0036] Furthermore, the limiting seat 323 includes a frame 3231 and a limiting cylinder 3232. The frame 3231 is fixedly installed on the top of the top plate 3213, and the limiting cylinder 3232 is fixedly installed on the top of the frame. Specifically, the frame 3231 is a circular cylindrical structure, and the top of the limiting cylinder 3232 is provided with an inclined surface. The presence of this inclined surface facilitates the installation of the shock absorber.

[0037] Furthermore, the end of the fixing column 324 away from the fixing cylinder 322 passes through the limiting cylinder 3232 and is set upward, and the fixing column 324 is offset from the axis of the limiting cylinder 3232. In this way, it can be ensured that the fixing column can contact the conical inner surface of the bottom of the shock absorber when it moves upward with the fixing cylinder, so as to achieve the fixed limiting of the shock absorber.

[0038] Reference Figure 6 In some embodiments, the automotive shock absorber outer cylinder rotary welding device further includes a cover 50 disposed around the base 10. The cover forms a box structure that covers the base 10. It should be noted that the front of the cover 50 is provided with a roller shutter door, and a three-color light strip is provided at the top of the roller shutter door for indication. A touch screen 510 and operation buttons 520 are provided on the front side wall of the cover 50. In addition, a right-side single door is provided on the right side of the cover 50, and a robotic arm observation window is provided on the right-side single door. A left-side single door is provided on the left side of the cover, and a welding observation room is provided on the left side wall of the cover, which can be used to observe the welding process. A rear single door is provided at the rear of the cover, and a welding parameter observation window is provided on the rear side wall of the cover.

[0039] In use, the turntable 310 rotates intermittently. During rotation, the welding fixture 320 and the shock absorber on it on one side can be rotated to the welding station. The welding robot 220 can then weld the outer cylinder of the shock absorber. After the shock absorber on that side is welded, the turntable 310 can be rotated again to move the shock absorber out, so that the shock absorber on that side of the welding fixture can be moved to the unloading station. At the same time, the welding fixture on the other side and the shock absorber on it can be moved to the welding station with the turntable. Welding and unloading operations can be performed on the shock absorbers at the welding station and the unloading station respectively. After unloading is completed, the shock absorber to be welded can be reassembled. In this way, continuous welding can be achieved during the continuous rotation of the turntable.

[0040] The above-described embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
