The electric push rod 22 is connected to the clamping plates 23 that are distributed oppositely. Two corresponding rollers 24 are rotatably connected to each clamping plate 23, and a guide roller 25 that is slidably matched with the inside of the mounting table 21 is arranged on the clamping plate 23;

[0030] The specific layout and installation method of the rollers 24 on the clamping plate 23 are as follows:

[0031] Each clamping plate 23 is symmetrically provided with two groups of connecting plates. One group of connecting plates includes two, and a rotating shaft is rotatably connected between the two connecting plates. The roller 24 is arranged on the rotating shaft. The connecting plates and the rotating shaft are shown in the figure but not labeled.

[0032] For further refinement of the solution of the embodiment of the present utility model, as Figure 1 shown in the figure, the horizontal adjustment assembly includes a horizontal roller 301, a sliding sleeve 32, and a fixing bolt 33. The horizontal roller 301 is arranged on the mounting frame 31. The sliding sleeve 32 is slidably matched with the horizontal roller 301 and is provided with a number of adjustment holes (not shown in the figure). The fixing bolt 33 is arranged on the sliding sleeve 32, and the fixing bolt 33 passes through the sliding sleeve 32 and is threadedly connected to one of the adjustment holes.

[0033] For further refinement of the above solution, as Figure 1 and Figure 3 shown in the figure, the fixing assembly includes a connecting rod 34, a clamping seat 35, a fastening screw 36, and a fixing plate 37. A vertically downward connecting rod 34 is arranged on the sliding sleeve 32. A clamping seat 35 is obliquely arranged at one end of the connecting rod 34. The fastening screws 36 are symmetrically arranged on the clamping seat 35. The fastening screws 36 are threadedly connected to the clamping seat 35, and one end of the fastening screw 36 is rotatably connected to the fixing plate 37.

The servo motor 12 and the worm and worm gear reducer 11 are arranged in the driving box 1. The input end of the worm and worm gear reducer 11 is connected to the servo motor 12, and the output end of the worm and worm gear reducer 11 is connected to the placing table 14.

[0035] It should be noted that both the servo motor 12 and the electric push rod 22 are electrically connected to the controller (the controller is not shown in the figure).

[0036] The working process of the present utility model:

[0037] First, place the cylinder block of the oil cylinder in the clamping area of the chuck 15. In this application, a chuck that can automatically clamp is used, specifically a three-jaw chuck, which belongs to the prior art principle and will not be described. Immediately, the cylinder block of the oil cylinder is stably clamped through the chuck 15. Initially, fix the welding torch on the clamping seat 35 and tighten its position through the fixed plates 37 on both sides. Then, place the guide sleeve on the cylinder block of the oil cylinder from top to bottom. The cylinder block of the oil cylinder and the guide sleeve are not shown in the figure. When the guide sleeve is sleeved on the cylinder block of the oil cylinder and reaches the clamping area of the clamping assembly, the controller immediately controls the clamping assembly to move synchronously towards the center. At this time, the four rollers 24 simultaneously contact the surface of the guide sleeve to limit its position on the cylinder block of the oil cylinder. The contact between the roller and the guide sleeve adopts a rolling friction method, with less contact wear. After the position of the guide sleeve and the cylinder block of the oil cylinder is limited, immediately adjust the orientation of the welding torch horizontally so that the welding head of the welding torch contacts the butt joint gap between the guide sleeve and the cylinder block of the oil cylinder and the welding torch remains inclined. Then, the orientation of the welding torch can be limited by the fixing bolts 33. Immediately, the welding torch works to perform spot welding on the contact butt joint between the two. At this time, the two are preliminarily fixed. Then, the clamping assembly can move away from the guide sleeve. After the clamping assembly moves away from the guide sleeve, the controller immediately controls the driving assembly to work. When the driving assembly works, it can drive the chuck 15 to rotate at a constant speed. At this time, the cylinder block of the oil cylinder and the guide sleeve can rotate together. While the two rotate synchronously, the welding torch can be used to complete the circumferential welding process of the butt joint between the two. When the circumferential welding process is completed, immediately control the chuck 15 to automatically release the locking of the cylinder block of the oil cylinder to achieve subsequent unloading. Then, replace a new set of the cylinder block of the oil cylinder and the guide sleeve to start a new vertical welding process.

[0038] Compared with the prior art, this device can realize the vertical circumferential welding process between the cylinder block of the oil cylinder and the guide sleeve, without manual intervention for welding, reducing the labor intensity and improving the welding efficiency. The degree of automation of the welding process is improved and the use effect is better.

[0039] In some embodiments, as Figure 1 shown, a fixed frame 13 is provided on the driving box 1, and a placing table 14 is rotatably connected to the fixed frame 13 through a bearing. In this embodiment, the fixed frame 13 can provide a supporting force for the placing table 14, avoiding the driving assembly directly bearing the gravity of the chuck 15 and the cylinder block of the oil cylinder, thereby extending the service life of the driving assembly.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
