The cylinder is installed on the cylinder adjusting seat by screws. The output end of the cylinder is connected to the connecting block. A hinge seat is provided at the bottom of the welding seat, and a welding torch is hinged on the hinge seat. With the help of the rotating component and the cylinder, the welding torch can rotate and move in the horizontal direction. At the same time, the welding torch can also rotate vertically with the help of a servo motor. It can realize multi-degree-of-freedom welding work with different needs and has high efficiency.

[0004] However, the following shortcomings still exist:

[0005] In the existing welding process of automotive inspection parts, spatter such as welding slag and sparks can easily cause burns to personnel, equipment failures, or fire hazards. Furthermore, spatter can interfere with the welding area and affect the welding quality. Therefore, those skilled in the art provide a welding device for automotive inspection processing to solve the problems mentioned in the background art. Utility Model Content

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figures 1-4As shown, this utility model provides a technical solution: a welding device for processing automotive inspection tools, including a base plate 1, a chip removal component 2 mounted on the top of the base plate 1, a work box 3 mounted on the top of the chip removal component 2 and a splash-proof component 4 connected to the work box 3, the splash-proof component 4 including a baffle 401, a hinge 402, a connecting plate 403, a cylinder 404 and a connecting plate 405, the baffle 401 is symmetrically installed on both sides of the outside of the work box 3, the baffle 401 is in the shape of a square box, the hinge 402 is symmetrically arranged on both sides between the baffle 401 and the work box 3, the connecting plate 403 is symmetrically connected to both sides of the bottom surface of the baffle 401, the connecting plate 403 is connected to the connecting plate 405 through the cylinder 404 below;

[0025] Furthermore, baffles 401 are symmetrically installed on both sides of the work box 3. The opening size of the work box 3 can be covered or exposed by the opening and closing action. When the cylinder 404 extends, it pushes the baffle 401 to rotate around the hinge 402 and close inwards in the work box 3 through the connecting plate 403. At this time, the square box structure of the baffle 401 completely covers the side of the work box 3, forming a closed protective barrier to intercept the welding slag, sparks and other spatter generated during the welding process, preventing them from splashing outwards and causing burns to personnel, equipment failure or fire hazards. At the same time, it reduces the interference of spatter on the welding area and indirectly improves the welding stability. When the cylinder 404 retracts, the connecting plate 403 pulls the baffle 401 to rotate outwards around the hinge 402 and opens it. The side opening of the work box 3 is fully exposed, which makes it easy for operators to quickly complete loading and unloading or workpiece adjustment. It achieves a dynamic balance between protective function and operation convenience.

[0026] As one implementation method in this embodiment, please refer to Figures 1-4 As shown, the bottom surface of the electric telescopic rod 7 is provided with an adjustment component 8. The adjustment component 8 includes a fixed plate 801, a connecting plate 802, a rotating shaft 803, a support plate 804, a support 805, and a cylinder 806. The fixed plate 801 is fixed to the bottom surface of the electric telescopic rod 7. The connecting plate 802 is connected to the bottom of the connecting plate 802. The rotating shaft 803 is connected to the inside of the connecting plate 802. The rotating shaft 803 is connected to the support plate 804 and the support 805 below. The support 805 is connected to the fixed plate 801 through the cylinder 806 in front.

[0027] Furthermore, the electric telescopic rod 7 can extend and retract, driving the adjustment component 8 to move vertically, thereby adjusting the height of the welding torch 9. When the cylinder 806 extends and retracts, it pushes or pulls the support 805 to rotate around the shaft 803. Since the support 805 is connected to the support plate 804 and the shaft 803, under the action of the cylinder 806, the support 805 drives the welding torch 9 to change its tilt angle within a certain range, so that the welding torch 9 can accurately align with welding parts of different shapes and positions, ensuring welding quality.

[0028] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, the chip removal assembly 2 includes a fixing base 201, a storage box 202, a positioning pin 203, and a sleeve plate 204. The fixing base 201 is fixed to the top surface of the base plate 1, and the storage box 202 is installed on the top surface of the fixing base 201. Insertion holes are provided on both sides of the top surface of the fixing base 201 and the storage box 202. The positioning pin 203 is located inside the storage box 202 and the fixing base 201, and the positions of the positioning pin 203 and the insertion holes correspond to each other. The sleeve plate 204 is fixed to the outside of the storage box 202.

[0029] Furthermore, when the debris in the storage box 202 is full, the positioning pin 203 is pulled out to release the fixed connection between the storage box 202 and the fixed base 201. The storage box 202 is then pulled outward from under the sleeve plate 204 to clean the debris stored in the storage box 202. After cleaning, the storage box 202 is pushed back into the bottom surface of the sleeve plate 204. After the storage box 202 is pushed into a certain position, the positioning pin 203 is inserted into the corresponding hole to fix it, so that the debris removal component 2 returns to normal working condition and continues to collect debris. This facilitates regular cleaning by staff, reduces cleaning difficulty, and minimizes the interference of debris on equipment operation.

[0030] Working principle: When it is necessary to fix the workpiece, the electric telescopic rod 5 extends, pushing the clamping plate 51 to move inward to the inside of the work box 3 until the clamping plates 51 on both sides tightly clamp the workpiece, ensuring the stability of the workpiece position during welding and avoiding welding deviation due to shaking. The electric telescopic rod 7, the adjusting component 8, and the welding torch 9 are stabilized by the fixing bracket 6. The extension and retraction of the electric telescopic rod 7 drives the adjusting component 8 to move up and down, adjusting the height of the welding torch 9. The extension and retraction of the cylinder 806 pushes the support 805 to rotate around the rotating shaft 803, causing the welding torch 9 to tilt, so that the welding torch 9 is accurately aligned with the welding area, ensuring welding quality. At the same time, the motor 91 drives the welding torch 9, so that the welding torch 9... During operation, baffles 401 are symmetrically mounted on both sides of the work box 3. When cylinder 404 extends, it pushes baffles 401 to close inward around hinge 402. The box structure forms a protective barrier to intercept splashes. When cylinder 404 retracts, baffles 401 open outward, exposing the opening for easy loading and unloading, achieving a balance between protection and ease of operation. During welding, the generated debris enters the waste storage box 202 through the mesh 31 inside the work box 3. When the waste storage box 202 is full, the positioning pin 203 is pulled out for cleaning. After cleaning, the bottom of the sleeve plate 204 is pushed back, and the positioning pin 203 is inserted to fix it, restoring the chip removal function. This facilitates regular cleaning and reduces equipment interference.

[0031] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
