Description

Technical Field

[0001] The present application relates to the field of welding technology, and in particular to a deep groove welding device for a hydraulic cylinder. Background Art

[0002] Currently, hydraulic cylinders are essential components in hydraulic systems, used to convert hydraulic energy into mechanical energy to achieve the movement of mechanical parts. Welding is a very important process in hydraulic cylinder production. Existing welding methods mainly include manual welding and automatic welding. Manual welding is the most traditional welding method. It is characterized by flexible and convenient operation, but the quality is greatly affected by the operator's level and has low efficiency. Automatic welding is characterized by fast speed and stable quality, but it is expensive. In existing welding, the reserved gap between the two hydraulic cylinders is closely related to the wall thickness of the hydraulic cylinders. When the wall thickness is greater, the reserved gap between the two hydraulic cylinders is larger, which can ensure that the two hydraulic cylinders are welded through and avoid lack of fusion.

[0003] For related technologies, please refer to the Chinese patent application with announcement number CN118905547A, which discloses a rotary welding device and welding method for hydraulic press manufacturing, including a base and a fixing seat fixedly connected to both sides of the middle of the upper end surface of the base. Hydraulic cylinders are provided inside the two fixing seats, and a clamping assembly for fixing the hydraulic cylinders is provided inside the fixing seat. The clamping assembly includes a rotating ring rotatably connected to the inside of the fixing seat, and a handle is fixedly connected between the two rotating rings. Support assemblies for supporting the tail end of the hydraulic cylinder are provided in the middle of both sides of the upper end surface of the base, and the support assembly includes a supporting arc plate, and a top column is fixedly connected to the middle lower end surface of the supporting arc plate.

[0004] With regard to the above-mentioned related technologies, before welding, the device needs to manually place the two hydraulic cylinders inside the fixing seat to complete the alignment of the hydraulic cylinders. However, when welding the hydraulic cylinders with larger wall thickness, a certain amount of gap needs to be maintained between the two hydraulic cylinders. When adjusting the distance between the two hydraulic cylinders, the two hydraulic cylinders are first brought close to each other, and the distance between the two hydraulic cylinders is measured during the process of approaching each other. When the preset distance is reached, the movement is stopped. In the process of adjusting the distance, not only a lot of time is wasted, but each group of hydraulic cylinders needs to be adjusted during welding, and the adjustment of the distance between the two hydraulic cylinders is not convenient.

The two spacer blocks 64 separate from each other and drive the two scrapers 25 to separate from each other, so that the spacing between the two scrapers 25 is consistent with the distance between the two hydraulic cylinders, which is beneficial to reduce the interference of the scraper 25 on the weld. When the adjustment is completed, the positioning rod 27 is flipped and the positioning rod 27 is removed from the positioning groove 26, which improves the convenience of cleaning the surface of the hydraulic cylinder.

[0041] The implementation principle of the hydraulic cylinder deep groove welding device of the embodiment of the present application is as follows: before the spacing is adjusted, the positioning rod 27 is flipped to make the positioning rod 27 arranged vertically, the electric push rod 61 pushes the moving rod 62 to move, and the moving rod 62 cooperates with the connecting rod 63 to drive the spacer block 64 to slide in the first sliding opening 16; when the spacer block 64 moves to the second sliding opening 17, the positioning rod 27 is located in the positioning groove 26, and the two spacer blocks 64 separate from each other while driving the two scrapers 25 to separate from each other, so that the spacing between the two scrapers 25 is consistent with the distance between the two hydraulic cylinders; when the adjustment is completed, the positioning rod 27 is flipped to move the positioning rod 27 out of the positioning groove 26, and when the connecting plate 13 is located inside the hydraulic cylinder, the bidirectional electric telescopic rod 454 contracts to drive the connection between the first guide rod 452 and the second guide rod 453 toward the rotating block 5 3 are brought closer, the first guide rod 452 and the second guide rod 453 cooperate to drive all the second telescopic rods 43 to extend, thereby making the deformation block 44 fit against the inner wall of the hydraulic cylinder, positioning and supporting the inner wall of the hydraulic cylinder; after the positioning is completed, the third moving member 23 and the moving plate 22 cooperate to move the welding gun 24 and the scraper 25 to the hydraulic cylinder, and the rotating motor 51 drives the rotating block 53 to rotate through the circular plate 52 and the connecting member 54, and the rotating block 53 and the second telescopic rod 43 drive the hydraulic cylinder to rotate. While the hydraulic cylinder is rotating, the welding gun 24 welds the two hydraulic cylinders, and the scraper 25 cleans the hot slag generated during the welding process. When welding hydraulic cylinders of the same specification, the distance between the scraper 25 and the spacer block 64 only needs to be adjusted once, and no subsequent adjustment is required, which improves the convenience of adjusting the distance between the two hydraulic cylinders.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
