For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] See also Figure 1-Figure 4 In the present embodiment, a fixing fixture for processing automobile sealing rings is provided, including a fixing table 1, on which three equally spaced slide grooves 2 are provided, a guide rod 3 is provided in the slide groove 2, a clamping rod 4 is slidably connected to the guide rod 3 at a position located inside the slide groove 2, a pressing block 5 is provided at the upper end of the clamping rod 4, a driving component 6 is provided at a position below the slide groove 2 on the lower side of the fixing table 1, an output end of the driving component 6 is fixedly connected to the lower end of the clamping rod 4, and the driving component 6 drives the clamping rod 4 to slide and move along the guide rod 3 in the slide groove 2.

[0024] In the utility model, the automobile sealing ring to be processed is sleeved on the outside of the three clamping rods 4, and then the driving assembly 6 on the lower side of the fixed platform 1 is used to drive the clamping rod 4 to slide on the guide rod 3 in the slide groove 2, so that the clamping rod 4 moves toward the center of the fixed platform 1, or the clamping rod 4 spreads toward the outer circle of the fixed platform 1, so as to adapt to sealing rings of different sizes, so that the clamping rod 4 clamps and fixes the sealing ring, and after the clamping rod 4 is against the inner ring of the sealing ring, the pressing block 5 is pressed on the upper side of the sealing ring, so as to fix the sealing ring to be processed.

[0025] Specifically, refer to Figure 3 The driving assembly 6 includes a fixing frame 61 fixed to the lower side of the fixing platform 1, a motor 62 is arranged on one side of the fixing frame 61, and a screw rod 63 is fixedly connected to the output end of the motor 62, and a slide seat 64 matching the screw rod 63 is threadedly connected to the screw rod 63. The motor 62, the screw rod 63 and the slide seat 64 form a screw rod structure, and the screw rod is used as a driving source to drive the clamping rod 4 to move, so that the clamping rod 4 can move to adapt to the size of the sealing ring.

[0026] Specifically, both sides of the clamping rod 4 are fitted on the inner wall of the slide groove 2, the lower end of the clamping rod 4 is fixedly connected to the upper side surface of the slide seat 64, and the upper end of the clamping rod 4 extends to a position above the fixed platform 1. The guide rod 3 plays a guiding role, so that the clamping rod 4 can move stably in the slide groove 2 under the drive of the driving assembly 6, thereby avoiding the phenomenon of flipping of the clamping rod 4 during movement.

[0027] Among them, the fixing frame 61 is set in a U shape, and both ends of the fixing frame 61 are fixedly connected with a mounting plate 65, and screw holes are opened on the mounting plate 65. The fixing frame 61 is fixed to the lower side of the fixing platform 1 along the length direction of the slide groove 2 through the mounting plate 65. The fixing frame 61 is fixed by using the mounting plate 65 to ensure that the fixing frame 61 can be fixed on the lower side of the fixing platform 1, thereby ensuring that the screw rod structure on the fixing frame 61 can be fixed under the fixing platform 1 for driving.

[0028] Specifically, refer to Figure 4 The upper side of the clamping rod 4 is recessed downward to form a connecting groove 41, and a spring 42 is arranged inside the connecting groove 41. The lower side of the pressure block 5 is fixedly connected to a connecting rod 51, and the lower end of the connecting rod 51 is fixedly connected to a limiting plate 52. During the clamping process of the sealing ring, the clamping rod 4 is against the inner side of the sealing ring. As the clamping rod 4 spreads outward to tighten the sealing ring, the pressure block 5 plays a limiting role to prevent the sealing ring from slipping off the clamping rod 4, thereby ensuring that the sealing ring can be fixed on the fixing platform 1.

[0029] Among them, the connecting rod 51 is slidably connected to the connecting groove 41 of the clamping rod 4 and the limit plate 52 is located inside the connecting groove 41, and the two ends of the spring 42 are fixedly connected to the lower end of the inner wall of the connecting groove 41 and the lower side of the limit plate 52 respectively. The spring 42 and the connecting rod 51 can make the pressure block 5 expand and contract at the upper end of the clamping rod 4, so that the sealing ring can be better pressed on the clamping rod 4, ensuring that the clamping rod 4 can clamp and fix the sealing ring.

[0030] Among them, the fixed table 1 is arranged in a circular shape, and three equally spaced mounting feet 7 are arranged on the outer ring surface of the fixed table 1. The mounting feet 7 are provided with mounting screw holes 8. Fasteners are screwed into the mounting screw holes 8 of the mounting feet 7, so that the fixed table 1 can be fixed on the processing equipment using the mounting feet 7.

[0031] Working principle: fasteners are screwed into the mounting screw holes 8 of the mounting feet 7, so that the fixing platform 1 can be fixed on the processing equipment using the mounting feet 7. The automobile sealing ring to be processed is sleeved on the outside of the three clamping rods 4, and then the driving assembly 6 on the lower side of the fixing platform 1 is used to drive the clamping rod 4 to slide on the guide rod 3 in the slide groove 2. The clamping rod 4 is against the inner side of the sealing ring. As the clamping rod 4 spreads outward, the sealing ring is tightened. The pressure block 5 plays a limiting role to prevent the sealing ring from sliding off the clamping rod 4, thereby ensuring that the sealing ring can be fixed on the fixing platform 1.
