Due to the lack of a dedicated welding tooling, and since the shock absorber barrel has a circular cross-section, it is difficult to clamp the shock absorber barrel; moreover, during the clamping process, the shock absorber barrel is prone to move, resulting in misalignment between the lower connecting plate and the joint, with low welding position accuracy, low welding efficiency, and high labor intensity. These are the deficiencies of the prior art. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model. The present utility model will be further described in conjunction with the drawings and embodiments:

[0017] As Figures 1-3 shown, a welding device for a lower connecting plate and a joint includes a bottom plate 1. Legs 6 are installed at the lower part of the bottom plate 1. A first positioning groove 2 for positioning the lower connecting plate is provided on the bottom plate 1, and second positioning grooves 3 for positioning the joint 8 are symmetrically arranged on both sides of the first positioning groove 2; A pressing mechanism 4 is provided above the first positioning groove 2, and a support shaft 5 is provided in front of the first positioning groove 2.

[0018] The bottom plate serves as the foundation of the entire welding device. The first positioning groove and the second positioning groove provided thereon can respectively position the lower connecting plate 7 and the joint 8 in the horizontal direction. The pressing mechanism 4 realizes the positioning of the workpiece in the vertical direction during the welding process, and the support shaft 5 plays a role in supporting and positioning. The cooperation of the above three structures facilitates the welding between the lower connecting plate 7 and the joint 8, reduces the human error during the welding process, and ensures the welding accuracy.

[0019] Further, the first positioning groove 2 is located at the rear end of the bottom plate 1, and the second positioning groove 3 is located at the front end of the bottom plate 1.

[0020] In actual operation, placing the long shock absorber cylinder 11 in the first positioning groove realizes the positioning of the lower connecting plate in the horizontal direction, and placing the short shock absorber cylinder 12 in the second positioning groove realizes the positioning of the joint in the horizontal direction.

[0021] Specifically, the pressing mechanism 4 includes a pneumatic cylinder 41 and a pressing plate 42. The piston rod of the pneumatic cylinder 41 is hinged to the middle of the pressing plate 42. When the pneumatic cylinder 41 is opened, the piston rod of the pneumatic cylinder 41 drives the pressing plate 42 to move downward. Since the diameters of the long shock absorber cylinder 11 and the short shock absorber cylinder 12 are different, the pressing plate will be in an inclined state. This design makes the pressing action more flexible and the force controllable.

[0022] In order to reduce the phenomenon that the shock absorber cylinder is damaged due to the direct contact between the pressing plate and the shock absorber cylinder, the present utility model fixes a first nylon rod 43 and a second nylon rod 44 at the lower part of the pressing plate 42. The two play a key role during the welding process, protecting the long shock absorber cylinder 11 and the short shock absorber cylinder 12 from being directly pressed and damaged, and ensuring the tight fit during welding. Specifically, the first nylon rod 43 and the second nylon rod 44 are both fixed to the pressing plate 42 by bolts, and the detachable design facilitates quickly replacing the nylon rods according to different welding requirements.

[0023] Further, the first positioning groove 2 is located at the rear end of the bottom plate 1, and the second positioning groove 3 is located at the front end of the bottom plate 1.

[0024] Further, the lower end of the support shaft 5 is fixed to the bottom plate 1, and a boss 51 for supporting the first positioning shaft is provided at the upper end of the support shaft 5. The boss 51 provides stable support for the lower connecting plate 7 during the welding process.

[0025] The process of using the present utility model to weld the lower connecting plate 7 and the joint 8 is as follows:

[0026] 1. Prepare the long shock absorber cylinder 11 with the lower connecting plate 7 and the short shock absorber cylinder 12 with the joint 8;

[0027] 2. Place the long shock absorber cylinder 11 in the first positioning groove 2, and pass the inner hole of the lower connecting plate 7 through the support shaft 5 until it reaches the position of the boss 51;

[0028] 3. Place the short shock absorber cylinder 12 in the second positioning groove 3 on the right side, so that the joint 8 is located above the lower connecting plate 7;

[0029] 4. Use a welding torch to weld the lower connecting plate and the joint 8 as required (the solder joint positions are as Figure 2 shown);

[0030] 5. Then turn the long shock absorber cylinder 11 by 180 degrees and place it in the first positioning groove 2 again; turn the short shock absorber cylinder 12 by 180 degrees and place it in the second positioning groove 3 on the left side, and weld the exposed gap between the lower connecting plate 7 and the joint 8 again. The welding is completed.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention.
