[0028] Positioning assembly 4 includes mounting seat 41 and V-shaped frame 42, mounting seat 41 is fixed to the top of support seat 1, V-shaped frame 42 is installed on mounting seat 41, and the horizontal line of the midpoint position of bending line of V-shaped frame 42 coincides with the central axis of connecting sleeve 32.

[0029] By installing electric cylinder 31 on support seat 1, connecting sleeve 32 is connected with electric cylinder 31, so that shock absorber cylinder body is fixed in connecting sleeve 32, by fixing mounting seat 41 on support seat 1 and installing V-shaped frame 42 on mounting seat 41, so that the horizontal line of the midpoint position of bending line of V-shaped frame coincides with the central axis of connecting sleeve 32, and then the position of shock absorbing ring in vertical direction corresponds to the position of shock absorber sleeve in vertical direction after preventing shock absorbing ring on V-shaped frame 42, so that the centering of shock absorbing ring and shock absorber cylinder body in vertical direction and horizontal direction is realized, then by controlling electric cylinder 31 to push shock absorber cylinder body to move, so that shock absorber cylinder body is attached on shock absorbing ring, welding assembly 2 can be used to weld and fix shock absorber cylinder body and shock absorbing ring, the centering difficulty during welding of shock absorber is reduced, and the welding efficiency is improved.

[0030] When connecting sleeve 32 is used to fix shock absorber cylinder body, arc support plate 36 is waved, so that spring 35 is compressed, and then the diameter of arc support plate 36 is increased, when the diameter of arc support plate 36 is matched with the diameter of shock absorber cylinder body, shock absorber cylinder body can be inserted into arc support plate 36, and arc support plate 36 clamps shock absorber cylinder body under the action of spring 35, so that the fixing effect of shock absorber cylinder body is realized.

[0031] Because the arc-shaped support plate 36 can move under the action of the spring 35 and the limiting rod 34, the welding equipment can weld shock absorber cylinders of different diameters, thus improving the compatibility of the welding equipment with various shock absorber products.

[0032] In the embodiments of this utility model, the mounting cylinder 33, the limiting rod 34, the spring 35, and the arc-shaped support plate 36 are all arranged in three sets around the circumference of the connecting sleeve 32. With the arrangement of the three sets of mounting cylinders 33, limiting rods 34, springs 35, and arc-shaped support plates 36, the clamping firmness of the limiting component 3 on the shock absorber cylinder is increased, thereby improving the alignment accuracy of the shock absorber cylinder and the shock absorber ring.

[0033] In an embodiment of this utility model, a positioning ear plate 43 is provided on the surface of the V-shaped frame 42 away from the connecting sleeve 32. A first threaded groove 44 is provided on the positioning ear plate 43, and a limiting bolt 46 is provided in the first threaded groove 44. A second threaded groove 45 is arranged in an array on the mounting base 41. The limiting bolt 46 passes through the first threaded groove 44 and connects with different second threaded grooves 45 to adjust the position of the V-shaped frame 42 on the mounting base 41. When it is necessary to adjust the placement position of the V-shaped frame 42 according to the size of the shock-absorbing ring, the limiting bolt 46 is first unscrewed from the inside of the first threaded groove 44, and then the positioning ear plate 43 changes from the locked state to the movable state. Then, the V-shaped frame 42 is directly adjusted to a suitable position, and the limiting bolt 46 is passed through the first threaded groove 44 and the second threaded groove 45 to tighten it.

[0034] In the embodiments of this utility model, two positioning ear plates 43 are symmetrically arranged along the bending line of the V-shaped frame 42, and two second threaded grooves 45 are arranged in an array to increase the connection between the V-shaped frame 42 and the mounting base 41 under the action of the two second threaded grooves 45 and the two positioning ear plates 43.

[0035] In an embodiment of this utility model, the welding assembly 2 includes an extension plate 21, a bracket 22, and a welding torch 23. The extension plate 21 is fixed to one side of the support base 1. The bracket 22 is located above the extension plate 21 and is fixedly connected to the side wall of the support base 1. The bracket 22 is L-shaped, and the welding torch 23 is placed on the L-shaped bracket 22.

[0036] After the shock absorber ring and the shock absorber cylinder are aligned and the electric cylinder 31 pushes the shock absorber cylinder and the shock absorber ring to fit together, the operator can take the welding torch 23 out of the bracket 22 and weld the connection between the shock absorber ring and the shock absorber cylinder by hand.

[0037] In an embodiment of this utility model, a first mounting plate 24 is provided on the welding torch 23, a second mounting plate 26 is provided on the side of the support base 1, a connecting line 25 is provided between the first mounting plate 24 and the second mounting plate 26, and a power supply electrically connected to the connecting line 25 is provided in the support base 1 so that the mobile power supply supplies power to the welding torch 23, thereby enabling the welding torch 23 to weld and fix the shock absorber cylinder and the shock absorber ring.

The positioning component 4 and the limiting component 3 are both installed on the lifting plate 12. A lifting drive component is installed inside the support base 1. The lifting drive component is connected to the lifting plate 12 to drive the lifting plate 12 to rise and fall. When the diameter of the shock absorber cylinder is too large, the lifting drive component drives the lifting plate 12 to rise, so that the electric cylinder 31 and the mounting base 41 rise synchronously. This increases the height of the connecting sleeve 32 and the V-shaped plate on the support base 1, so that the large-diameter shock absorber cylinder can be fitted into the connecting sleeve 32, avoiding collision between the shock absorber cylinder and the support base 1.

[0039] In an embodiment of this utility model, the inner wall of the arc-shaped support plate 36 is provided with a wear-resistant pad 37, so as to increase the clamping friction and clamping stability between the arc-shaped support plate 36 and the shock absorber cylinder under the action of the wear-resistant pad 37.
