When the extending end of the telescopic cylinder 20 extends, the pressure-bearing section 313 drives the connecting rod 31 to rotate under the pushing of the extending end of the telescopic cylinder 20, so that the flat pushing piece 34 pushes the bearing ring 1 to drive the bearing ring 1 into the clamping tool.

In a specific embodiment, the main body section 311 includes a first section 311A and a second section 311B parallel to each other, and a connecting section 311C connected between the first section 311A and the second section 311B, wherein the hinge section 312 and the pressure-bearing section 313 are disposed on the first section 311A, the horizontal pushing member 34 is connected on the second section 311B, and the second section 311B is disposed close to the sliding plate 10 relative to the first section 311A, so that the horizontal pushing member 34 is closer to the sliding plate 10, and therefore, the axial length of the horizontal pushing member 34 can be effectively reduced, and therefore, when the rotation angle of the connecting rod 31 is fixed, the distance of the end surface of the horizontal pushing member 34 far from the connecting rod 31 moving in the longitudinal direction is reduced, and it is ensured that the radian of the movement of the horizontal pushing member 34 is relatively small, and it is possible to avoid the influence on the movement of the bearing ring 1 due to an excessively large deflection angle of the.

Bearing 32 is mounted on the side of second section 311B adjacent to skateboard 10, and the outer race of bearing 32 is in interference fit with second section 311B. The screw 33 is screwed with the second segment 311B and the screw 33 passes through the inner race of the bearing 32, and a cavity 321 is formed between the screw 33 and the inner race of the bearing 32. In one embodiment, a flange 331 is protruded from an end of the screw 33 near the bearing 32.

The horizontal pushing component 34 corresponds to the accommodating cavity 110, the horizontal pushing component 34 is positioned at one side of the connecting rod 31 close to the sliding plate 10, and the horizontal pushing component 34 is installed at one end of the screw 33 corresponding to the flange 331. Specifically, the horizontal pushing member 34 is substantially a plate-shaped structure, the end surface of the horizontal pushing member 34 close to the sliding plate 10 is provided with a receiving groove 341, the screw 33 is disposed through the horizontal pushing member 34, and the flange 331 is movably received in the receiving groove 341, so as to prevent the horizontal pushing member 34 from being separated from the screw 33, i.e., to ensure the movable clamping connection relationship between the horizontal pushing member 34 and the screw 33. It should be noted that, when the flange 331 rotates in the receiving groove 341, the axis of the pushing component 34 and the axis of the screw 33 are parallel or intersect. The end surface of the flat pushing member 34 far from the sliding plate 10 is convexly provided with an arc-shaped surface 342, the arc-shaped surface 342 is partially positioned in the cavity 321, and the arc-shaped surface 342 movably supports against the inner ring edge of the bearing 32.

When the bearing ring 1 is used, when the connecting rod 31 rotates to drive the horizontal pushing piece 34 to hit the bearing ring 1, the horizontal pushing piece 34 can move in all directions relative to the screw rod 33, so that the hitting end face (namely, the end face close to the sliding plate 10) of the horizontal pushing piece 34 can be attached to the end face of the bearing ring 1, the acting force received by all places of the bearing ring 1 is consistent or tends to be consistent, and the bearing ring 1 is prevented from being damaged due to uneven stress at all places. In addition, when the flat pushing member 34 is attached to the bearing ring 1 by extrusion, the arc-shaped surface 342 of the flat pushing member 34 abuts against the inner ring edge of the bearing 32, so that, in the striking process, if the flat pushing member 34 rotates to a certain extent, the bearing 34 is beneficial to the rotation of the flat pushing member 34, the problem that the flat pushing member 34 cannot be attached to the bearing ring 1 due to unsmooth rotation is avoided, and the bearing ring 1 can be smoothly pushed into the clamping tool is ensured.

When the connecting rod 31 rotates clockwise to hit the bearing ring 1, the elastic part 35 is compressed, and when the extending end of the telescopic cylinder 20 retracts, the connecting rod 31 is reset under the elastic force of the elastic part 35, and the operation is convenient. In addition, an extension plate 116 is connected to one side of the sliding plate 10, which is located at the elastic member 35, a bolt 117 is connected to the extension plate 116 in a threaded manner, the bolt 117 abuts against one side of the connecting rod 31, which is away from the elastic member 35, and by rotating the bolt 117, the distance from the flat pushing member 34 to the sliding plate 10 before striking the bearing ring 1 can be adjusted. Specifically, the extension plate 116 is in an L-shaped structure, the long side of the extension plate 116 is connected to the slide plate 10, and the bolt 117 is threadedly connected to the short side of the extension plate 116. In the present embodiment, the elastic member 35 is a spring.

Referring to fig. 1 and 2, the working process of the bearing ring driving mechanism of the present invention is as follows:

the bearing ring 1 on the material channel rolls into the containing cavity 110, then the sliding plate 10 is moved relative to the frame 2 to the containing cavity 110, the telescopic cylinder 20 is started, the extending end of the telescopic cylinder 20 extends to push against the upper end of the connecting rod 31, and further the flat pushing piece 34 connected to the lower end of the connecting rod 31 is driven to move towards the sliding plate 10, and further the flat pushing piece strikes the bearing ring 1, and finally the bearing ring 1 is sent into the clamping tool, so that the fixing effect on the bearing ring 1 is realized, and the bearing ring 1 is conveniently cut (for example, an inner ring channel of the bearing ring 1 is cut).

According to the bearing ring driving-in mechanism provided by the invention, the axis of the extending end of the telescopic cylinder 20 is parallel to the mounting plane of the clamping tool, so that the telescopic cylinder 20 is prevented from occupying too much space in front of the clamping tool, and a tool rest is facilitated to move; in addition, when the horizontal pushing piece 34 strikes the bearing ring 1, the horizontal pushing piece 34 can move relative to the screw 33, so that the acting force received by the bearing ring 1 is consistent or tends to be consistent, the bearing ring 1 is prevented from being damaged due to uneven stress at each part, meanwhile, the bearing ring 1 can smoothly enter the clamping tool, the driving stability is good, and the processing quality is improved.

In light of the foregoing description of preferred embodiments in accordance with the invention, it is to be understood that numerous changes and modifications may be made by those skilled in the art without departing from the scope of the invention.
