[0046] The mounting groove 11 is symmetrically arranged on the placing table 1;

[0047] The telescopic piece 12 is arranged in the mounting groove 11;

[0048] The pushing plate 13 is in sliding cooperation with the round roller 14 and is connected with the telescopic piece 12.

[0049] Further refinement of the embodiment scheme of the utility model is shown in Figure 1 and Figure 2 The rotating clamping assembly comprises a driving motor 23, a rotating disc 24 and parallel clamping jaws 25,

[0050] The driving motor 23 is connected with the servo motor 22;

[0051] The rotating disc 24 is connected with the driving motor 23;

[0052] The parallel clamping jaws 25 are arranged on the rotating disc 24 and are circumferentially distributed about the rotating disc 24.

[0053] Further optimization of the above embodiment scheme is that rubber pads are symmetrically arranged on the parallel clamping jaws 25 and the plurality of parallel clamping jaws 25 are independently controlled by the controller, and the rubber pads are not shown in the figure.

[0054] Further refinement of the embodiment scheme of the utility model is shown in Figure 1 and Figure 2 The three-axis device 21 comprises a cross slide and an electric push rod,

[0055] The cross slide is arranged on the mounting frame 2 and is driven by a screw structure;

[0056] The electric push rod is arranged on the cross slide and is connected with the servo motor 22.

[0057] It should be noted that the telescopic piece 12, the three-axis device 21, the servo motor 22, the driving motor 23 and the parallel clamping jaws 25 are electrically connected with the controller, the controller is not shown in the figure and can be arranged on the mounting frame 2.

[0058] The working process of the utility model is as follows:

[0059] Firstly, several bearing rings are sequentially sleeved through the round roller 14 (the diameter of the round roller 14 is matched with the inner hole diameter of the bearing ring), and then the bearing rings are neatly stacked, and the lowermost bearing ring is in contact with the pushing plate 13. At the same time, the controller controls the three-axis equipment 21 and the driving motor 23 to operate according to the pre-set program, so that one of the parallel clamps 25 moves to the upper side of the round roller 14, and then the controller controls the telescopic part 12 to move, thereby driving the bearing rings to move upward as a whole. At this time, the uppermost bearing ring moves to the pre-set area height, and then the parallel clamp 25 currently opposite to the round roller 14 can complete the clamping of one bearing ring and make the bearing ring separate from the round roller 14;

[0060] After completing the clamping and upward transfer of one bearing ring, the controller controls the driving motor 23 to work, thereby driving the rotating disc 24 to rotate at a pre-set angle. Then, another empty parallel clamp 25 moves to the upper side of the round roller 14 (the rotating disc 24 does not hinder the sleeve type chuck during the rotating process), and then the telescopic part 12 moves again to move the bearing rings upward at equal intervals. Then, the clamping and upward transfer of one bearing ring can be completed again. The above process is repeated until each parallel clamp 25 clamps one bearing ring;

[0061] Then, the controller controls the servo motor 22 to work, so that the driving motor 23 cooperates with the rotating disc 24, the parallel clamp 25 and the bearing ring to deflect (specifically, the rotating disc 24 deflects by 90 degrees clockwise, and the area height of the deflection of the rotating disc 24 is pre-set, thereby avoiding collision and hindrance with other objects). After the rotation is completed, the sleeving surface of the bearing ring is parallel to the sleeve type chuck, and then the controller controls the three-axis equipment 21 and the driving motor 23 to operate according to the pre-set program, thereby making the inner hole of one of the bearing rings opposite to the sleeve type chuck and having the same center as the sleeve type chuck. Then, the forward and backward movement of the three-axis equipment 21 can make the inner hole of one of the bearing rings exactly sleeve on the sleeve type chuck. Then, the sleeve type chuck can automatically complete the locking of the bearing ring. After the self-locking is completed, the parallel clamp 25 corresponding to the bearing ring first releases the clamping and then moves away from the sleeve type chuck, so as not to affect the subsequent turning process. The turning process of the outer surface of the bearing ring belongs to the prior art, which is not described in the present application. It should be noted that, during the sleeving of one of the bearing rings on the sleeve type chuck, the remaining bearing rings are spaced apart from the sleeve type chuck and do not contact each other;

[0062] After the outer surface of the bearing ring is turned, the corresponding parallel clamp 25 moves to the sleeving area again, clamps the bearing ring and moves it outward to transfer it away (the sleeve type chuck automatically releases the locking during the transfer and unloading). Then, the above process is repeated to realize the sequential feeding, turning and unloading processes of the other bearing rings on the sleeve type chuck;

[0063] Compared with the prior art, the device does not need manual placing of the bearing ring on the clamping end of the expanding sleeve type turning fixture before turning processing, can automatically feed and automatically unload and transfer the processed bearing ring after the turning processing is completed, and then feeds a new bearing ring to realize the assembly line operation, so manual intervention is not needed all the time, the automation degree of the bearing ring processing and feeding is significantly improved, and the feeding position is accurate.

[0064] In other embodiments, a visual camera and a buzzer electrically connected with the visual camera are arranged on the placing table 1; the embodiments are not shown in the drawings; the embodiments can capture the bearing ring on the circular roller 14 in real time through the visual camera, feed back a signal to the controller if the bearing ring on the circular roller 14 is all processed, and then control the buzzer to make a sound to remind the worker to feed in time.

[0065] The basic principle, main features and advantages of the utility model are shown and described above. The skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and the description in the specification are only to illustrate the principle of the utility model, and the utility model will have various changes and improvements without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model claimed for protection.
