[0023] The technical solution of the utility model is further elaborated in detail below in conjunction with the accompanying drawings and specific embodiments of the specification.

[0024] Embodiment 1:

[0025] The present application provides a self-centering automobile welding fixture, comprising a base 1; a placement table 2 is fixedly installed at the central position of the base 1, and an adsorption mechanism 3 is arranged in the inner cavity of the placement table 2;

[0026] The adsorption mechanism 3 includes an air cavity 301, air holes 302 and a connecting tube 303. The air cavity 301 is opened in the inner cavity of the placement table 2. The air holes 302 are opened on the surface of the placement table 2 at equal intervals. A connecting tube 303 is provided on one side of the placement table 2.

[0027] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when welding automobile parts, personnel place the automobile parts on the surface of the placement table 2, and can connect the connecting pipe 303 to the external air pump, and then use the external air pump to suck the gas inside the air cavity 301 outward, so that suction can be generated inside the air hole 302, so that the automobile parts can be fixed on the surface of the placement table 2, so that the device can prevent deviation and damage during the processing of the automobile parts, thereby further improving the fixation of the automobile parts by the device, and further ensuring the quality of the processing of the automobile parts by the device.

[0028] Further, the surface of the base 1 is provided with four sets of centering clamping mechanisms 4 on the side of the placing table 2, and a feeding mechanism 8 is provided between two sets of centering clamping mechanisms 4. The feeding mechanism 8 includes an inclined plate 801, a rotating groove 802 and a feeding roller 803. The inclined plate 801 is obliquely installed on the surface of the base 1, and the inner side of the inclined plate 801 is provided with rotating grooves 802 at equal intervals, and the feeding roller 803 is rotatably installed inside the rotating groove 802;

[0029] Specifically, Figure 1 , Figure 2 As shown, when the device is processing a part, the part is placed on the surface of the inclined plate 801. Since the inclined plate 801 is an inclined structure, the loading roller 803 can rotate inside the rotating groove 802 during the upward sliding process on the part, thereby making it convenient for personnel to place the automobile parts on the surface of the placement table 2, and then quickly perform welding processing on the automobile parts.

[0030] Further, the centering clamping mechanism 4 includes an electric slide rail 401, a slider 402 and a clamping plate 403. The electric slide rail 401 is fixedly installed on the surface of the base 1. The slider 402 is slidably installed on the surface of the electric slide rail 401. The clamping plate 403 is fixedly installed on the surface of the slider 402. A mounting groove 5 is provided on the top surface of the slider 402. The slider 402 is symmetrically provided with a mounting mechanism 7 on the groove wall of the mounting groove 5. The mounting mechanism 7 includes a mounting cavity 701, a fixing plate 702 and a spring 703. The mounting cavity 701 is provided on the groove wall of the mounting groove 5. A fixing plate 702 is slidably installed inside the mounting cavity 701. A spring 703 is installed on the surface of the fixing plate 702. A fixing cavity 6 is provided at the bottom of the clamping plate 403. The size of the fixing cavity 6 matches the size of one end of the fixing plate 702.

[0031] Specifically, Figure 1 , Figure 2As shown, the automobile parts are placed on the surface of the placement table 2, and the bottom of the parts are fixed by the adsorption mechanism 3. Then, the personnel open the electric slide rail 401 through the external controller, and drive the clamping plate 403 to move on the surface of the electric slide rail 401 through the slider 402. The parts placed on the surface of the placement table 2 are fixed by the inner side of the clamping plate 403, and the parts of the placement table 2 can be self-centering and clamped by four sets of centering clamping mechanisms 4, which is convenient for the device to process and weld the parts. When the device is in use, the personnel can replace the clamping plate 403 as needed due to the different sizes of the parts. During the replacement process, the personnel can pull the fixing plate 702 outward to make the fixing plate 702 move. 02 is separated from the interior of the fixing cavity 6, and then the clamping plate 403 is taken out from the interior of the mounting groove 5, and then a new clamping plate 403 is fixed to the automotive parts. At this time, the personnel inserts the bottom of the clamping plate 403 into the interior of the mounting groove 5, and then the personnel pulls the fixing plate 702 to make the fixing plate 702 retract into the interior of the mounting cavity 701. When the fixing plate 702 corresponds to the fixing cavity 6, the fixing plate 702 is released, and the fixing plate 702 will pop outward under the elastic force of the fixing spring 703 inside it, so that the clamping plate 403 can be fixed on the surface of the mounting slider 402. Through the setting of the mounting mechanism 7, it is convenient for personnel to replace the clamping plate 403 according to the size and shape of the welded parts, thereby further improving the applicability of the device.

[0032] Working principle: personnel place automobile parts on the surface of the placement table 2, connect the connecting pipe 303 to the external air pump, and then use the external air pump to suck the gas inside the air cavity 301 outward, so that suction can be generated inside the air hole 302, so that the automobile parts can be fixed on the surface of the placement table 2, and then personnel use the external controller to open the electric slide rail 401, and use the slider 402 to drive the clamping plate 403 to move on the surface of the electric slide rail 401, and fix the parts placed on the surface of the placement table 2 through the inner side of the clamping plate 403, and the four sets of centering clamping mechanisms 4 can self-center and clamp the parts on the placement table 2, so that the device can process and weld the parts.

[0033] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified and replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
