[0045] The housing 41 is a hollow cylindrical structure;

[0046] One end of the bottom of the first screw rod 47 is rotatably connected to the bottom of the inner wall of the housing 41, and one end of the top of the first screw rod 47 is fixedly connected to the first motor;

[0047] The driving ring 46 is threadedly connected to the first screw rod 47, and one end of a plurality of first connecting rods 42 is hingedly connected to the outer wall of the driving ring 46 at equal intervals along its circumference;

[0048] The other end of the first connecting rod 42 is hinged with a slider 44;

[0049] A sliding groove corresponding to the slider 44 is provided at the bottom of the inner wall of the housing 41;

[0050] One end of the second connecting rod 45 is connected to the slider 44, and the other end of the second connecting rod 45 extends out of the housing 41 and is fixedly connected to the grab block 43;

[0051] When in use, the first motor drives the first screw rod 47 to rotate, so that the drive ring 46 can be lifted and lowered along the length direction of the first screw rod 47. When the drive ring 46 moves downward, under the action of the first connecting rod 42, the slider 44 slides outward, so that the grabbing block 43 can move outward. After the inner wall of the O-ring is expanded, the O-ring is grabbed, and then the front and rear moving components 2 and the lifting and moving components 3 are cooperated to move the grabbed O-ring to the processing table 6 to realize the loading of the O-ring.

[0052] In this embodiment, a side of the grab block 43 away from the second connecting rod 45 is arranged in an arc shape.

[0053] In this embodiment, the forward and backward moving assembly 2 includes a second motor 21, a second screw rod 23, a bearing seat 24 and a moving block 22;

[0054] There are two sets of bearing seats 24, which are installed on the frame 1 at intervals;

[0061] The working principle of the utility model is as follows:

[0062] The first motor drives the first screw rod 47 to rotate, so that the driving ring 46 can be lifted and lowered along the length direction of the first screw rod 47. When the driving ring 46 moves downward, under the action of the first connecting rod 42, the slider 44 slides outward, so that the grabbing block 43 can move outward. After the inner wall of the O-ring is expanded, the O-ring is grabbed. Then, in conjunction with the front and rear moving components 2 and the lifting and moving components 3, the grabbed O-ring is moved to the processing table 6 to realize the loading of the O-ring. The movable grabbing block 43 can meet the needs of grabbing O-rings of different diameters. It is highly practical and suitable for large-scale promotion and use.
