[0018] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments of the present application.

[0019] Embodiment 1: Refer to Figures 1-4 The oil seal trimming chuck comprises a supporting seat 1, a driving shaft 2 rotatably arranged in the supporting seat 1, a gear set connected between the driving shaft 2 and an electric motor, and the driving shaft 2 is driven to rotate by the gear set when the electric motor is started. The upper end of the driving shaft 2 extends through the supporting seat 1 and is fixedly connected with a rotating table 3. The central axis of the driving shaft 2 coincides with the central axis of the rotating table 3, and both are vertically arranged. The driving shaft 2 is driven to rotate, thereby driving the rotating table 3 to rotate.

[0020] A sliding groove 6 is formed in the top of the rotating table 3, and three sliding grooves 6 are arranged in a circular array along the central axis of the rotating table 3. Three pairs of limiting strips 4 are fixedly arranged on the inner wall surface of the top of the rotating table 3. Each pair of limiting strips 4 is arranged on the two sides of the sliding groove 6, and the length direction of the limiting strips 4 is consistent with the length direction of the sliding groove 6. The length extension line of the sliding groove 6 passes through the central axis of the rotating table 3. A sliding block 5 is slidably arranged between each pair of limiting strips 4. The end of the sliding block 5 is fixedly connected with a clamping block 7. The clamping block 7 extends through the sliding groove 6 and extends above the rotating table 3. The clamping block 7 is limited by the sliding block 5 and can stably slide along the sliding groove 6. A non-slip pad is fixedly arranged on one side surface of the clamping block 7. When the clamping block 7 clamps the oil seal, the non-slip pad can prevent the oil seal from being separated from the clamping block 7.

[0021] A linkage mechanism is fixedly arranged in the rotating table 3. The linkage mechanism is fixedly connected with the sliding block 5. The position of the clamping block 7 can be adjusted by the linkage mechanism through the sliding block 5, so that the oil seal of different sizes can be clamped. Figure 1 As shown in the drawings, the linkage mechanism comprises an electric telescopic rod 8 and a pair of linkage frames 9. The end of the electric telescopic rod 8 is fixedly connected with one sliding block 5. The one end of the linkage frame 9 is provided with a first slot 91, and the other end is provided with a second slot 92. The length direction of the first slot 91 is consistent with the length direction of the one end of the linkage frame 9. The length direction of the second slot 92 is consistent with the length direction of the other end of the linkage frame 9. The end of the pair of linkage frames 9 is slidably connected with the end of one sliding block 5 through the first slot 91. A rotating shaft 93 is rotatably arranged in the middle of the linkage frame 9. The end of the rotating shaft 93 is fixedly connected with the inner wall of the rotating table 3. The linkage frame 9 can rotate around the rotating shaft 93. The other two sliding blocks 5 are rotatably connected with a connecting rod 10. The end of the connecting rod 10 is slidably arranged in the second slot 92. The length direction of the electric telescopic rod 8, the linkage frame 9 and the connecting rod 10 is horizontally arranged.

[0022] As shown in the drawings, Figure 1As shown, the electric telescopic rod 8 is started to drive the rightmost slider 5 to move farther, the movement of the right slider 5 can drive the linkage frame 9 to rotate, causing the two linkage frames 9 to approach each other at the end of the connecting rod 10, so that the two connecting rods 10 can drive the corresponding sliders 5 to move farther, so that the three sliders 5 can move away from the center of the rotating table 3, and the distance between the clamping blocks 7 can be increased. At this time, the larger diameter oil seal can be clamped by the clamping block 7; when the electric telescopic rod 8 is started to drive the rightmost slider 5 to move closer, the three sliders 5 can be simultaneously moved to the center of the rotating table 3, and the smaller diameter oil seal can be clamped.

[0023] Working principle: during the working process of the oil seal burr trimming chuck, first adjust the space between the clamping blocks 7 to be sufficient to accommodate the next oil seal, then place the oil seal on the upper surface of the rotating table 3, start the electric telescopic rod 8 to drive the rightmost slider to approach the center of the rotating table 3, and through the linkage frame 9 and the connecting rod 10, the other two sliders 5 can be simultaneously driven to approach the center of the rotating table 3, so that the three clamping blocks 7 can clamp the oil seal, and different diameter oil seals can be clamped. Then, start the motor to drive the rotating table 3 to rotate as a whole through the gear set, so as to drive the oil seal to rotate, finally, adjust the position of the trimming head of the external trimming mechanism, so that the trimming head contacts the burr of the oil seal. The oil seal during rotation can be trimmed by the trimming head. Since the upper end of the clamping block 7 is lower than the height of the upper end of the oil seal, the burr on the outer side of the upper end of the oil seal can be trimmed after being clamped by the chuck, and the burr on the inner side of the upper end of the oil seal can also be trimmed. The trimmed ring-shaped burr will fall on the upper surface of the rotating table 3. During trimming, the trimmed burr will be bounced outwards due to inertia after being separated from the oil seal body. The bounced ring-shaped burr will fall on the upper surface of the rotating table. Since all the transmission components are hidden inside the rotating table 3, the surface of the rotating table 3 is relatively flat, and the fallen burr can be easily cleaned.

[0024] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
