Detailed Implementation

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-4 As shown, the welding device for hydraulic cylinder processing proposed in this utility model includes a base 1, and a rotary welding mechanism 2 and a push-limiting mechanism 3 set on the base 1. The rotary welding mechanism 2 includes a support plate 4 and a turntable 5. The support plate 4 is set on the base plate and has a through hole 6. The turntable 5 is rotatably set on the support plate 4. An electric push rod 7 is set on the inner side wall of the turntable 5. Multiple sets of electric push rods 7 are symmetrically arranged. A welding gun 8 is set at the output end of the electric push rod 7. The hydraulic cylinder is fixed on the push-limiting mechanism 3. When the electric push rod 7 is started, the welding gun 8 is driven to approach the welding point of the hydraulic cylinder. The turntable 5 is driven to rotate the electric push rod 7 and the welding gun 8 within a certain angle. Multiple sets of welding guns 8 are used for synchronous welding to improve the welding effect.

[0022] like Figure 3 and 4 As shown, a gear ring 9 is provided on the outer wall of the turntable 5, and a motor 10 is installed on the base plate. A gear 11 is provided at the output end of the motor 10. The gear 11 meshes with the gear ring 9. When the motor 10 is started, the gear 11 is driven to rotate, and the gear 11 drives the gear ring 9 to rotate, thereby adjusting the welding position. Meanwhile, the hydraulic cylinder remains fixed, which can prevent the hydraulic cylinder from shifting during rotation and ensure the welding quality.

[0023] like Figure 4 As shown, the welding torch 8 is equipped with a dust suction hood 12, and a vacuum cleaner 13 is installed on the side wall of the turntable 5. A connecting pipe 14 connects the vacuum cleaner 13 and the dust suction hood 12. The connecting pipe 14 is corrugated. When the vacuum cleaner 13 is activated, the welding fumes can be collected through the connecting pipe 14 and the vacuum cleaner 13. The corrugated connecting pipe 14 ensures that the dust suction head can always remain connected when the welding torch 8 moves.

[0024] like Figure 1 and 2As shown, the push-limiting mechanism 3 includes an adjusting groove 15 and a push plate 16. The adjusting groove 15 is located on the base plate and is positioned on one side of the support plate 4. A lead screw 17 is rotatably mounted inside the adjusting groove 15. One end of the lead screw 17 is shaft-connected to a motor 18 fixedly mounted on the side wall of the base plate. The push plate 16 is slidably located inside the adjusting groove 15 and is threadedly connected to the lead screw 17. A movable plate 19 is mounted on the push plate 16. A fixed plate 20 is mounted on the base plate and is positioned on the other side of the support plate 4. Two sets of fixed plates 20 and movable plates 19 are symmetrically arranged. Cylinders 21 are mounted on both the fixed plates 20 and movable plates 19. A clamping plate 22 is provided at the output end of the cylinder 21. The hydraulic cylinder is fixed between the fixed plates 20 through the clamping plate 22 of the cylinder 21. The parts to be welded are then fixed between the movable plates 19. The motor 18 is started, which drives the lead screw 17 to rotate. The lead screw 17 drives the push plate 16 to move, pushing the welding parts closer to the hydraulic cylinder. This method is convenient to use.
