[0024] For this specific embodiment, the support base 101 is used to support the installation of the fixing component.

[0025] Among them, the first baffle 102 is fixedly connected to the support base 101 and is located on one side of the support base 101; the auxiliary abutting member 103 is arranged on one side of the support base 101; the two clamping structures 104 are respectively arranged at both ends of the support base 101; the spacing adjusting member 105 is arranged on one side of the support base 101; the bracket 106 is fixedly connected to the spacing adjusting member 105 and is located on one side of the spacing adjusting member 105; the connecting seat 107 is fixedly connected to the bracket 106 and is located on one side of the bracket 106; the clamping frame 108 is fixedly connected to the connecting seat 107 and is located on one side of the connecting seat 107; the clamping member 109 is arranged on one side of the clamping frame 108. When welding and grinding the automobile door frame, according to the size of the automobile door frame, simultaneously control the two spacing adjusting members 105 to adjust the spacing of the clamping frames 108 on the bracket 106, then place both ends of the automobile door frame on the clamping frames 108 respectively, then make the front end fit against the first baffle 102, and then simultaneously control the clamping members 109 on both sides to simultaneously abut against both ends of the automobile door frame. When controlling the auxiliary abutting member 103 to abut against the rear end of the automobile door frame, the fixing of the automobile door frame can be completed, effectively improving the stability during welding or grinding. By simplifying the fixing process, the problem of the existing welding and grinding jig for an automobile door frame is solved.

[0029] When using a welding and grinding jig for an automobile door frame described in this embodiment, when welding and grinding the automobile door frame, according to the size of the automobile door frame, simultaneously control the two spacing adjusting members 105, control the driving motor 114 to drive the screw rod 115 to rotate, the rotation of the screw rod 115 drives the slider 116 to slide in the adjusting frame 113, and the sliding of the slider 116 is used to adjust the position of the bracket 106, and then adjust the spacing between the two clamping frames 108 according to the size of the automobile door frame. Then, place the two ends of the automobile door frame on the clamping frames 108 respectively, then make the front end fit the first baffle 102, and then simultaneously control the clamping members 109 on both sides, control the electric telescopic cylinder 118 to drive the connecting plate 119 to drive the abutting block 120 to move, so that the abutting block 120 abuts and fixes the automobile door frame, thereby completing the fixation of the two ends of the automobile door frame. Then, control the hydraulic cylinder 111 to drive the second baffle 112 to cooperate with the first baffle 102 to assist in fixing the rear end of the automobile door frame, and the overall fixation of the automobile door frame can be completed, effectively improving the stability during welding or grinding.
