Description

Technical Field

[0001] This utility model relates to the field of door panel processing technology, specifically to a welding fixture for automotive door panels. Background Technology

[0002] The car door panel provides a passage for the driver and passengers to enter and exit the vehicle, isolates external interference, and to a certain extent reduces side impacts and protects the occupants. The door body includes the inner door panel, the outer door panel, the door window frame, the door reinforcing beam, and the door reinforcing plate. Welding fixtures are required during the manufacturing process of the car door.

[0003] The prior art patent document with publication number CN221065012U provides: a welding fixture for automobile door panels, including a welding fixture body. In use, the door panel is installed in the corresponding groove. Later, through the cooperation of the positioning post and the positioning tube, the parts between the door panels are limited and fixed by the extrusion force of the limiting plate before welding, which facilitates the subsequent welding. The welding head moves up and down inside the fixing hole, and the fixing hole provides vertical limiting force for the welding head. Later, the door panel is pushed by the thrust generated by the positioning post through the support mechanism, so that the door panel and one end of the welding head are quickly separated. Later, different shaped grooves can be used according to the shape of the door panel. Later, the movable seat is pulled inside the fixing groove to move the door panel outward. After being moved out, the door panel is pushed out of the groove through the opening, which facilitates the subsequent material removal.

[0004] Although the device has many beneficial effects, the following problems still exist: During the use of the device, the sliding of the movable seat is prone to squeezing the limiting block, causing the torsion spring to rotate, resulting in insufficient stability and causing the movable seat to fall off, affecting the welding use; secondly, the welding head position is fixed during the use of the device, which is not convenient to adjust to adapt to different welding needs and needs to be improved. In view of this, we propose an automotive door panel welding fixture. Utility Model Content

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This type of automotive door panel welding fixture works by turning on the first motor to drive the worm gear to rotate, which in turn causes the two worm wheels to rotate simultaneously, driving the two shafts to rotate simultaneously. This, in turn, causes the two gears to rotate simultaneously, moving the two toothed plates outward. The movable seat can be removed and replaced with a movable seat with a different model of positioning slot to adapt to the needs of different automotive door panels. Controlling the first motor to drive the worm gear to rotate in the opposite direction causes the two toothed plates to move inward and engage with the slots. The longitudinal sliding of the movable seat prevents compression, allowing the toothed plates to move laterally to prevent disengagement. The spring's rebound force facilitates the compression of the toothed plates to move inward, improving the stability of the movable seat.

[0021] This type of automotive door panel welding fixture uses a third motor to drive a lead screw to rotate, which in turn moves a slider and moves the welding head to the desired position. By activating a second motor, a rotating plate is driven to rotate, allowing the welding head to be moved to any position for welding, thus adapting to different welding needs.

[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural schematic diagram of an embodiment of an automotive door panel welding fixture, including:

[0035] Please see Figures 1-5 This embodiment of an automotive door panel welding fixture includes a base 1, a mounting groove 2 on the top of the base 1, a movable seat 3 slidably connected to the bottom of the mounting groove 2, a positioning groove 4 on the top of the movable seat 3, and a mounting assembly 5 fixed to the side wall of the base 1. The mounting assembly 5 includes a first motor 501, a worm gear 502 fixed to the output end of the first motor 501, worm wheels 503 meshing at both ends of the outer circumference of the worm gear 502, rotating shafts 504 fixed to the inner circumference of each of the two worm wheels 503, gears 505 fixed to the other ends of the outer circumference of each of the two rotating shafts 504, and gears 505 meshing with toothed plates 506. A spring 507 is fixed to one end of the toothed plate 506. Slots 508 are provided on both sides of the movable seat 3. A fixing frame 6 is welded to the top of the base 1, and a first cylinder 7 is fixed to the top of the fixing frame 6. A welding assembly 8 is fixedly installed at the output end of cylinder 7. The first motor 501 and the first cylinder 7 are electrically connected to an external power source. By turning on the first motor 501, the worm gear 502 is driven to rotate, thereby causing the two worm wheels 503 to rotate simultaneously, driving the two rotating shafts 504 to rotate simultaneously, which in turn causes the two gears 505 to rotate simultaneously, driving the two toothed plates 506 to move outward. The movable seat 3 can be removed and replaced with a movable seat 3 with a different model of positioning groove 4 to adapt to the needs of different car door panels. The first motor 501 is controlled to drive the worm gear 502 to rotate in the opposite direction, thereby causing the two toothed plates 506 to move inward and engage with the slot 508. The longitudinal sliding of the movable seat 3 prevents the toothed plates 506 from being squeezed, allowing them to move laterally to prevent them from disengaging. The rebound force of the spring 507 facilitates the squeezing of the toothed plates 506 to move inward, which helps to improve the stability of the movable seat 3.

[0036] It is worth noting that, in order to facilitate the adjustment of the welding head position, the welding assembly 8 specifically includes a movable frame 801. A second motor 802 is fixedly installed at the bottom of the inner cavity of the movable frame 801. A rotating plate 803 is fixedly installed at the output end of the second motor 802. A third motor 804 is fixedly installed on the outer circumference of the rotating plate 803. A lead screw 805 is fixedly installed at the output end of the third motor 804. A slider 806 is threadedly connected to the outer circumference of the lead screw 805. A welding head 807 is fixedly installed at the bottom of the slider 806. The first motor 501 and the third motor 804 are electrically connected to an external power source. By turning on the third motor 804, the lead screw 805 is rotated, thereby moving the slider 806 and moving the welding head 807 to the desired position. By turning on the second motor 802, the rotating plate 803 is rotated, thereby moving the welding head 807 to any position for welding, which is convenient to adapt to different welding needs.

[0037] Next, in order to improve stability, specifically, the size of the mounting groove 2 matches the size of the movable seat 3, and the size and position of the toothed plate 506 match the size and position of the slot 508. By using the mounting groove 2 which matches the size of the movable seat 3, the lateral swaying of the movable seat 3 is prevented from affecting the welding. By using the toothed plate 506 which matches the size and position of the slot 508, the installation of the movable seat 3 is made more stable.

[0038] Meanwhile, in order to facilitate the control of the movement direction of the two toothed plates 506, specifically, the threads at both ends of the outer circumference of the worm 502 are in opposite directions, and the rotating shaft 504 is rotatably connected to the inner cavity side wall of the base 1. By setting the threads at both ends in opposite directions, it is easy to make the two worm wheels 503 rotate in opposite directions at the same time when the worm 502 rotates, so that the two toothed plates 506 move inward or outward at the same time.

[0039] Furthermore, in order to limit the movement of the slider 806, specifically, a groove 808 is provided at the bottom of the rotating plate 803. The size and position of the groove 808 match the size and position of the slider 806. By matching the size and position of the slider 806 with the groove 808, the slider 806 is prevented from rotating with the lead screw 805.

[0040] It is worth noting that, in order to facilitate the welding of the car door panel, specifically, the position of the rotating plate 803 matches the position of the positioning groove 4, and the lead screw 805 is rotatably connected to one side wall of the slide 808. By using the rotating plate 803, which matches the position of the positioning groove 4, dead corners where the welding head 807 cannot be welded are avoided in the car door panel.

[0041] Finally, to facilitate the removal of the car door panel, specifically, a groove 9 is provided at the bottom of the mounting groove 2, and a second cylinder 10 is fixed at the bottom of the groove 9. A through hole 11 is provided at the bottom of the positioning groove 4. The second cylinder 10 is electrically connected to an external power source. By opening the second cylinder 10, the output end passes through the through hole 11 and pushes the car door panel upward, which facilitates the removal of the material later.

[0042] In addition, the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this utility model does not involve improvements to the internal structure and methods.

[0044] First motor 501: Y90S-2;

[0045] Second motor 802: Y80S-2;

[0046] Third motor 804: Y70S-2;

[0047] Cylinder 7: CA2Y-Z40;

[0048] Second cylinder 10: CA2Y-Z30.

[0049] Combination Figures 1-5 The specific usage process of the automotive door panel welding fixture in this embodiment is as follows:

[0050] 1: When this device is needed for welding automotive door panels, start the first motor 501 to make the worm gear 502 rotate, which drives the two worm wheels 503 to rotate simultaneously, thereby causing the two rotating shafts 504 to drive the two gears 505 to rotate simultaneously, and then causing the two toothed plates 506 to move outward. Replace the movable seat 3 of the positioning slot 4 with a different model, and control the first motor 501 to rotate in the opposite direction to make the two toothed plates 506 move inward into the slot 508.

[0051] 2: Start the third motor 804 to rotate the lead screw 805 and move the slider 806 to the desired position. Start the second motor 802 to rotate the rotating plate 803 and move the welding head 807 to any position. Start the first cylinder 7 to move the welding head 807 downward for welding.
