Description

Technical Field

[0001] This invention relates to the field of vehicle door welding technology, and more specifically to a vehicle door welding device. Background Technology

[0002] Modern vehicle door panel welding equipment can achieve rapid welding of door panels with high precision and efficiency, meeting actual market demands. However, some problems still exist in actual processing. For example, before the vehicle door panel is placed on the workbench for processing, the clamping part of the fixture needs to be clamped. After processing, when the door panel needs to be removed, the clamping part of the fixture needs to be separated from the door panel, thus affecting the processing efficiency. To solve the above problems, this invention proposes a vehicle door welding device. Summary of the Invention

[0003] (1) Technical problems to be solved

[0004] The purpose of this invention is to overcome the shortcomings of the prior art, adapt to practical needs, and provide a vehicle door welding device that simply places the door panel on the processing table, automatically clamps it during welding, and automatically releases it after welding, thereby improving processing efficiency and solving the above-mentioned technical problems.

[0005] (2) Technical solution

[0006] To achieve the objectives of this invention, the technical solution adopted is as follows:

[0007] A vehicle door welding device includes a base, a support frame fixedly mounted on the side of the base, a hydraulic cylinder fixedly mounted on the top of the support frame, a mounting cover fixedly mounted on the piston rod of the hydraulic cylinder, a rodless cylinder fixedly mounted on each side of the inner side wall of the mounting cover, an electric rail fixedly mounted between the moving ends of the two rodless cylinders, a moving block fixedly mounted on the moving end of the electric rail, a welding gun fixedly mounted inside the moving block, and the welding nozzle of the welding gun protruding from the moving block, a pressing component mounted on the mounting cover, a placement frame fixedly mounted inside the base, and a clamping component cooperating with the pressing component at each of the four corners of the top of the placement frame.

[0008] The pressing assembly includes a backing frame that is reciprocally movable on the lower side of the mounting cover. The top surface of the backing frame is provided with multiple grooves, and the bottom surface of the mounting cover is fixedly provided with multiple limiting plates. The multiple limiting plates can reciprocate within the multiple grooves, and a support spring is fixedly provided between the bottom of the limiting plate and the bottom of the groove.

[0009] The clamping assembly includes a placement block fixedly mounted on the top of the placement frame. A support block is provided on the upper side of the placement block. A rotating shaft is rotatably connected between the inner walls of the support block. A flip plate is fixedly connected to the rotating shaft. A torsion spring is sleeved on the rotating shaft. One end of the torsion spring is fixedly connected to the flip plate, and the other end is fixedly connected to the support block.

[0010] A shifting component is provided between the support block and the placement block, and four shifting driving components are provided on the inner wall of the abutment frame, with the shifting driving components cooperating with the shifting component.

[0011] The displacement assembly includes a sliding groove disposed on the top surface of the placement block, a reciprocating push block disposed in the sliding groove, the push block being fixedly connected to the bottom of the support block, and a first movable spring being fixedly connected between the sliding groove and the push block.

[0012] The displacement drive assembly includes a movable groove disposed on the inner wall of the abutment frame, a first inclined block that can reciprocate is disposed in the movable groove, a second movable spring is fixedly disposed between the first inclined block and the inner wall of the abutment frame, and a second inclined block is fixedly disposed on the side of the support block away from the mounting cover.

[0013] When the flip plate is in its natural state of not contacting the first inclined block, the highest point of the flip plate is located at one-third of the distance from the bottom to the top of the second inclined block.

[0014] The vehicle door panel is moved between the flip plate and the placement blocks to the top surface of the four placement blocks, allowing the vehicle door panel to be placed on the four placement blocks. When welding is required, the hydraulic cylinder is activated, driving the mounting cover to move downwards, allowing the abutment frame to move downwards and contact the flip plate. The abutment frame first pushes the flip plate downwards to rotate and press it onto the vehicle door panel, clamping the vehicle door panel. Then, the mounting cover, carrying the welding gun, continues to move downwards to weld the vehicle door panel (the extension function is achieved through the setting of the limit plate, groove, and support spring, allowing the abutment frame to push the flip plate to press the door panel and continue to allow the welding head to move downwards). This allows for automatic clamping during welding and automatic release after welding, making it easier to quickly put the door panel into processing and quickly remove the door panel after processing, improving processing efficiency.

[0015] (3) Beneficial effects:

[0016] A. The pressing and clamping components automatically clamp the door panel during welding and automatically release it after welding, making it easier to quickly insert the door panel into the processing and quickly remove it after processing, thus improving processing efficiency.

[0017] B. By setting up the shift drive component and the shift component, the original clamping position can be welded. During the processing, there is no need to move the door panel to change the clamping position, thereby improving work efficiency.

[0018] C. Because the inclined surfaces of the first and second inclined blocks will first come into contact with each other, pushing the second inclined block to move and take the flip plate away from the original clamping position, the frame will then push the flip plate to rotate downwards and press it onto the vehicle door panel to achieve clamping. This avoids the flip plate moving while clamping the door panel, which would cause mutual friction and damage. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-10 The present invention is further illustrated by the embodiments:

[0032] A vehicle door welding device includes a base 1, a support frame 2 fixedly mounted on the side of the base 1, a hydraulic cylinder 3 fixedly mounted on the top of the support frame 2, a mounting cover 4 fixedly mounted on the piston rod of the hydraulic cylinder 3, a rodless cylinder 5 fixedly mounted on each side of the inner side wall of the mounting cover 4, an electric rail 6 fixedly mounted between the moving ends of the two rodless cylinders 5, a moving block 7 fixedly mounted on the moving end of the electric rail 6, a welding gun 880 fixedly mounted inside the moving block 7, and the welding nozzle of the welding gun 880 protruding from the moving block 7, a pressing component 8 mounted on the mounting cover 4, a placement frame 9 fixedly mounted inside the base 1, and a clamping component 909 cooperating with the pressing component 8 at the four corners of the top of the placement frame 9.

[0033] The pressing assembly 8 includes a backing frame 81 that is reciprocally movable on the lower side of the mounting cover 4. The top surface of the backing frame 81 is provided with a plurality of grooves 82. The bottom surface of the mounting cover 4 is fixedly provided with a plurality of limiting plates 83. The plurality of limiting plates 83 can reciprocate within the plurality of grooves 82. A support spring 84 is fixedly provided between the bottom of the limiting plate 83 and the bottom of the groove 82.

[0034] The clamping assembly 909 includes a placement block 91 fixedly mounted on the top of the placement frame 9. A support block 92 is provided on the upper side of the placement block 91. A rotating shaft is rotatably connected between the inner walls of the support block 92. A flip plate 93 is fixedly connected to the rotating shaft. A torsion spring is sleeved on the rotating shaft. One end of the torsion spring is fixedly connected to the flip plate 93, and the other end is fixedly connected to the support block 92.

[0035] The vehicle door panel is moved between the flip plate 93 and the placement block 91 to the top surface of the four placement blocks 91, so that the vehicle door panel can be placed on the four placement blocks 91. When welding is required, the hydraulic cylinder 3 is activated, which drives the mounting cover 4 to move downward, so that the abutment frame 81 moves downward and contacts the flip plate 93. The abutment frame 81 will first push the flip plate 93 to rotate downward and press it on the vehicle door panel, so that the flip plate 93 clamps the vehicle door panel. Then the mounting cover 4 continues to move downward with the welding gun to weld the vehicle door panel (the extension function is achieved by setting the limit plate 83, the groove 82 and the support spring 84, so that after the abutment frame 81 pushes the flip plate 93 to press the door panel, it can continue to move the welding head downward). Thus, it can automatically clamp during welding and automatically release after welding, so as to facilitate the quick insertion of the door panel into the processing and the quick removal of the door panel after processing, thereby improving processing efficiency. The compressive strength of the support spring 84 is greater than the torsional strength of the torsion spring. Therefore, the support spring 84 is only compressed during the process of the flipping plate flipping first and then continuing to move downward.

[0036] A shifting component 49 is provided between the support block 92 and the placement block 91. Four shifting drive components 50 are provided on the inner wall of the abutment frame 81. The shifting drive component 49 cooperates with the shifting component 50, and the four shifting drive components are respectively located above the four shifting components.

[0037] The shifting assembly 49 includes a sliding groove 911 disposed on the top surface of the placement block 91. A reciprocating push block is disposed in the sliding groove 911. The push block is fixedly connected to the bottom of the support block 92. A first movable spring 950 is fixedly connected between the inner wall of the sliding groove 911 and the push block.

[0038] The shifting drive assembly 50 includes a movable groove 501 disposed on the inner wall of the abutment frame 81. A first inclined block 502 that can reciprocate is disposed in the movable groove 50. A second movable spring 951 is fixedly disposed between the first inclined block 502 and the inner wall of the abutment frame 81. A second inclined block 999 is fixedly disposed on the side of the support block 92 away from the mounting cover 4. When the flip plate 93 does not abut against the first inclined block 502, the highest point of the flip plate 93 is located at one-third of the distance from the bottom to the top of the second inclined block 999 (e.g., Figure 5 As shown in the diagram, this causes the inclined surface of the first inclined block 502 to first abut against the inclined surface of the second inclined block 999, pushing the second inclined block 999 to move, taking the flip plate 93 away from its original clamping position. After the flip plate leaves its original clamping position, the abutment frame 81 will push the flip plate 93 to rotate downwards and press it onto the vehicle door panel to achieve clamping.

[0039] When spot welding is required at the clamping position, the rodless cylinder and electric track are activated, moving the moving block 7 to the position to be spot welded, that is, above the clamping part. At the same time, the first inclined block 502 is pushed to move outward of the abutment frame 81 to above the second inclined block 999. Then, the hydraulic cylinder 3 is activated, moving the mounting cover 4 downward, so that the inclined surface of the first inclined block 502 abuts against the inclined surface of the second inclined block 999, pushing the second inclined block 999 to move, taking the flipping plate 93 away from the original clamping position. Then, the abutment frame 81 pushes the flipping plate 93 downward to rotate and press it onto the vehicle door panel to achieve clamping, thus enabling electric welding at the original clamping position. During the processing, there is no need to move the door panel to change the clamping position, thereby improving work efficiency.

[0040] The welding gun is existing technology, so its structure will not be described in detail.

[0041] The working principle of this invention includes the following process:

[0042] The vehicle door panel is moved between the flip plate 93 and the placement block 91 to the top surface of the four placement blocks 91, so that the vehicle door panel can be placed on the four placement blocks 91. When welding is required, the hydraulic cylinder 3 is activated, which drives the mounting cover 4 to move downward, so that the abutment frame 81 moves downward and contacts the flip plate 93. The abutment frame 81 will first push the flip plate 93 to rotate downward and press it on the vehicle door panel, so that the flip plate 93 clamps the vehicle door panel. Then the mounting cover 4 continues to move downward with the welding gun to weld the vehicle door panel (the extension function is achieved by setting the limit plate 83, the groove 82 and the support spring 84, so that after the abutment frame 81 pushes the flip plate 93 to press the door panel, it can continue to move the welding head downward). Thus, it can automatically clamp during welding and automatically release after welding, so as to facilitate the quick insertion of the door panel into the processing and the quick removal of the door panel after processing, thereby improving processing efficiency.

[0043] When spot welding is required at the clamping position, the rodless cylinder and electric track are activated, moving the moving block 7 to the position to be spot welded, that is, above the clamping part. At the same time, the first inclined block 502 is pushed to move outward of the abutment frame 81 to above the second inclined block 999. Then, the hydraulic cylinder 3 is activated, moving the mounting cover 4 downward, so that the inclined surface of the first inclined block 502 abuts against the inclined surface of the second inclined block 999, pushing the second inclined block 999 to move, taking the flipping plate 93 away from the original clamping position. Then, the abutment frame 81 pushes the flipping plate 93 downward to rotate and press it onto the vehicle door panel to achieve clamping, thus enabling electric welding at the original clamping position. During the processing, there is no need to move the door panel to change the clamping position, thereby improving work efficiency.

Those skilled in the art can readily grasp the spirit of the present invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of the present invention, they are all within the protection scope of the present invention.
