Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic cylinder welding, specifically a support device for hydraulic cylinder welding. Background Technology

[0002] Hydraulic cylinders are key components of construction machinery. Their function is to convert hydraulic energy into mechanical energy. When manufacturing hydraulic cylinders, welding equipment is required, and the welding process must be coordinated with a support device.

[0003] However, a utility model patent with authorization announcement number CN216607827U discloses an easily adjustable support device for tower welding, belonging to the field of tower welding support devices. This easily adjustable support device for tower welding includes a base plate, with fixed seats fixedly connected to both sides of the top of the base plate. A telescopic groove is chiseled at the top of the fixed seat, and a connecting seat is slidably connected to the inner wall of the telescopic groove. A threaded groove is chiseled at the bottom of the connecting seat, and a threaded rod is threadedly connected inside the threaded groove. A groove is chiseled at the bottom of the fixed seat near the telescopic groove, and a driven gear is fixedly connected to the bottom of the threaded rod. The driven gear is located in the groove, and a driving gear meshes with the bottom of the driven gear. This allows the support device to be used such that, when the tower welding support device is in use, the gear drives the threaded rod to rotate, and the threaded structure formed between the threaded rod and the connecting seat drives the connecting seat to extend and retract, thereby adjusting the height of the support device and facilitating the alignment of the welding positions between tower sections later.

[0004] Based on existing solutions and actual production and processing applications, current support devices for hydraulic cylinder welding still have some problems. For example, the tower is clamped by components such as a second slider, a fixed rod, a spring, and a clamping plate, but the clamping structure is unstable. Moreover, the angle needs to be manually adjusted when welding the tower, which is cumbersome and reduces the welding speed. In addition, one end of the tower is prone to tilting during welding, reducing stability. Therefore, we propose a support device for hydraulic cylinder welding to solve the problems mentioned above.

Detailed Implementation

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Please see Figure 1-6The present invention provides the following technical solution: a support device for welding hydraulic cylinders, comprising a base plate 1, a mounting plate 2, a first connecting shaft 3, an adjusting disc 4, a gear ring 5, a gear 6, a second connecting shaft 7, a motor 8, a long groove 9, an adjusting block 10, a limiting rod 11, a limiting roller 12, a connecting rod 13, a connecting hole 14, an adjusting plate 15, an electric telescopic rod 16, a bearing plate 17, a threaded rod 18, and a guide rod 19.

[0042] Example 1: Existing methods use components such as a second slider, a fixing rod, a spring, and a clamping plate to clamp the tower cylinder. However, the clamping structure is unstable. Therefore, this example uses the following technical solution: Figure 1 , Figure 3 , Figure 4 and Figure 6 Since the limiting structure includes a long groove 9, an adjusting block 10, a limiting rod 11, a limiting roller 12, a connecting rod 13, a connecting hole 14, an adjusting plate 15, and an electric telescopic rod 16, the right end of the adjusting plate 4 has a long groove 9 opened at equal angles. The adjusting block 10 is slidably connected inside the long groove 9. The connecting rod 13 is threaded into the inside of the connecting hole 14. The limiting roller 12 slides on the upper side of the base plate 1 through the adjusting plate 15. Therefore, the outer cylinder of the oil cylinder to be processed is placed on the limiting rod 11 set at equal angles, and a limiting roller 12 of appropriate size is selected and placed on the left side of the adjusting plate 15. On the side, rotate the limiting roller 12 to make the connecting rod 13 threaded into the inside of the connecting hole 14, and install the limiting roller 12 on the adjusting plate 15. When the electric telescopic rod 16 works, it drives the adjusting plate 15 to move to the left, so that the limiting roller 12 moves to the left between the limiting rods 11 set at equal angles, so that the adjusting block 10 set at equal angles slides outward at the corresponding position, so that the outer end of the limiting rod 11 set at equal angles abuts against the inner wall of the outer cylinder. The "T" shaped structure of the adjusting block 10 can prevent the limiting rod 11 from disengaging from the adjusting plate 4, thereby facilitating stable clamping of the outer cylinder.

[0043] Example 2: Existing methods for welding tower sections require manual angle adjustment, which is cumbersome and reduces welding speed. Therefore, this example addresses this issue by employing the following technical solution: Figure 1 , Figure 3 and Figure 4Since the adjustment structure includes a first connecting shaft 3, an adjustment disc 4, a gear ring 5, a gear 6, a second connecting shaft 7, and a motor 8, the right rear end of the mounting plate 2 is rotatably connected to the first connecting shaft 3, and the front end of the gear ring 5 is meshed with the gear 6. The adjustment disc 4 is in a rotating structure on the upper side of the base plate 1 through the gear 6 and the gear ring 5. Therefore, when the motor 8 is working, it drives the second connecting shaft 7 to rotate on the mounting plate 2. When the second connecting shaft 7 rotates, it drives the gear 6 to rotate, so that the gear 6 meshes with the gear ring 5, so that the adjustment disc 4 rotates on the mounting plate 2 through the first connecting shaft 3. When the adjustment disc 4 rotates, it drives the clamped outer cylinder of the oil cylinder to rotate, thereby facilitating the adjustment of the angle of the outer cylinder of the oil cylinder.

[0044] Example 3: In existing systems, one end of the tower is prone to tilting during welding, reducing stability. Therefore, this example addresses this issue by implementing the following technical solution: Figure 1 , Figure 2 , Figure 4 and Figure 5 Since the threaded rod 18 is threaded to the front end of the bearing plate 17, and the front middle end of the bearing plate 17 is nested with the guide rod 19, the bearing plate 17 has a lifting structure on the upper side of the base plate 1 through the threaded rod 18 and the guide rod 19. Therefore, when the threaded rod 18 rotates, the front middle end of the bearing plate 17 slides upward on the guide rod 19. The threaded rod 18 and the guide rod 19 drive the bearing plate 17 to rise, so that the rear upper end of the bearing plate 17 fits against the lower end of the outer cylinder of the oil cylinder, thereby easily increasing stability. All the electrical components mentioned above are existing technologies and will not be described in detail here.

[0045] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
