[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] like Figures 1 to 5 As shown, this utility model provides a fixing fixture for welding automotive door frames, including a base frame 1. A first position adjustment component 2 is installed on the front and rear sides of the base frame 1. The first position adjustment component 2 is connected to an angle adjustment component 3. The angle adjustment component 3 is connected to a support frame 4. A second position adjustment component 5 is installed on the support frame 4. The second position adjustment component 5 is connected to a pressure fixing component 6. The first position adjustment component 2 and the second position adjustment component 5 allow the position of the pressure fixing component 6 to be arbitrarily adjusted to fix automotive door frames of different sizes. Furthermore, two or more pressure fixing components 6 can cooperate with each other to fix automotive parts, thereby facilitating the welding of automotive door frames.
[0031] Specifically, the base frame 1 has symmetrically arranged fixing ears 7 fixedly connected to both sides, and fixing bolts 8 are provided on the fixing ears 7.
[0032] Furthermore, the first position adjustment component 2 includes a rack 201 fixed on the base frame 1, the rack 201 being meshed with a connecting gear 202, the connecting gear 202 being connected to a first motor 203 via a motor shaft, the first motor 203 being connected to a movable frame 204, and the movable frame 204 being slidably connected to the base frame 1 via a slide rail 205.
[0033] Furthermore, the angle adjustment component 3 includes a vertical plate 301 fixedly connected to the top surface of the movable frame 204. A second motor 302 is installed on the vertical plate 301. The second motor 302 is connected to a drive gear 303 through a motor shaft. The drive gear 303 is meshed with a driven gear 304. A connecting column 305 is fixedly connected to the middle of one side of the driven gear 304. The connecting column 305 passes through the vertical plate 301 and is fixedly connected to the support frame 4. This allows the support frame 4, the second position adjustment component 5, the pressure fixing component 6, and other structures to be kept away from the base frame 1, so as to facilitate the placement and removal of the car door frame and not easily affect the loading and unloading of the car door frame.
[0034] It is worth noting that the end of the support frame 4 away from the upright plate 301 is fixedly connected to a support foot 9. The position of the support foot 9 corresponds to that of the base frame 1. When the support frame 4 is in a horizontal position, it can support the support frame 4 to maintain the stability of the support frame 4.
[0035] It is worth noting that the second position adjustment component 5 includes a third motor 501 mounted on the support frame 4. The output end of the third motor 501 is connected to a lead screw 502. A positioning slide rod 503 is provided on one side of the lead screw 502. A moving table 504 is connected between the lead screw 502 and the positioning slide rod 503.
[0036] It is worth mentioning that the pressure fixing component 6 includes a cylinder 601 mounted on the moving platform 504. The piston rod of the cylinder 601 passes through the moving platform 504 and is connected to the pressure foot 602. The cylinder 601 is used to press the pressure foot 602 onto the car door frame, which, together with the base frame 1, forms a clamping and fixing in the vertical direction.
[0037] Among them, the first motor 203, the second motor 302, the third motor 501, and the cylinder 601 are existing technologies and will not be described in detail; at the same time, this utility model also includes a power supply, a controller, and a switch, which are not the main technical points of this patent and will not be described in detail.
[0038] Working principle and process: The car door frame is placed on the base frame 1 and limited by corresponding welding fixtures. The first motor 203 of the first position adjustment component 2 is started, which in turn causes the connecting gear 202 to rotate. Since the moving frame 204 is connected to the base frame 1 through the slide rail 205 and the position of the connecting gear 202 relative to the moving frame 204 is fixed, the connecting gear 202 can move on the rack 201, which in turn drives the moving frame 204 to move. This allows adjustment of the lateral position of the angle adjustment component 3, the support frame 4, the second position adjustment component 5, and the pressure fixing component 6. The second motor 302 of the angle adjustment component 3 is started, which in turn causes the driving gear 303 to drive the driven gear 304 to rotate. The connecting column 305 drives the support frame 4 to rotate, so that the support frame 4 is horizontally placed above the car door frame, and the bottom of the support foot 9 contacts the base frame 1 to make the support frame 4 more stable. The third motor 501 of the second position adjustment component 5 is started, and the lead screw 502 rotates. Under the action of the thread and the positioning slide rod 503, the moving table 504 drives the corresponding pressure fixing component 6 to move longitudinally, so that the pressure fixing component 6 is above the position to be clamped and fixed. The cylinder 601 of the pressure fixing component 6 is started, and the cylinder 601 extends. The pressure foot 602 presses on the corresponding position of the car door frame. With the cooperation of the base frame 1, the car door frame can be clamped and fixed from the top and bottom to facilitate the welding of the car door frame.
