[0023] The position of clamp 5 is automatically adjusted through linear extension structure 6, so that clamp 5 can quickly fix or release bearing part, reduce the time of manual operation, thereby improving the efficiency of production;Through linear extension structure 6, clamp 5 is driven to tightly adhere to the outer surface of bearing part, so that the part can be more stably fixed, and the accuracy and stability in the processing process are guaranteed;Without complex clamping plate, clamping block and screw combination, the process of installation and disassembly is simplified, the labor intensity of workers is reduced, and at the same time, it is also helpful to reduce the error caused by human factors;Since clamp 5 can move along sliding groove 4 to adapt to bearing parts of different sizes, the versatility and flexibility of the device are increased.

[0024] Each clamp 5 is provided with an adaptive abutting unit 7, which includes an abutting terminal 8. An installation slot is formed on the clamp 5, and a spring 9 is arranged in the installation slot. The two ends of the spring 9 are fixedly connected between the bottom wall of the installation slot and the outer wall of the abutting terminal 8. A telescopic guide rod 10 is arranged between the abutting terminal 8 and the outer wall of the clamp 5. The abutting terminal 8 can be finely adjusted according to the actual size of the bearing part through the spring 9, so as to realize the adaptive abutting effect. During the fixing process, the abutting terminal 8 can stably contact and apply force to the surface of the part, thereby reducing the machining error caused by inaccurate positioning. The telescopic guide rod 10 ensures that the abutting terminal 8 can smoothly expand and contract under the action of the spring 9, without the phenomenon of jamming, thereby further improving the reliability of the device. The spring 9 provides soft pressure, which effectively prevents unnecessary scratches or other damage to the surface of the part during the fixing process, thereby ensuring the quality of the part.

[0025] As a preferred embodiment of the above embodiment, a rubber layer is arranged on the outer surface of the abutting terminal 8, and anti-skid lines are arranged on the surface of the rubber layer. The rubber layer has a high friction coefficient, which can increase the friction between the abutting terminal 8 and the bearing part, so that the fixing is more firm, and good stability can be maintained even in the case of high-speed rotation or vibration. The rubber material is soft and elastic, which effectively prevents scratches or other damage caused by the direct contact of the hard abutting terminal with the surface of the part, thereby further protecting the surface quality of the part.

The uniformly distributed adaptive abutting units 7 can better adapt to bearing parts of different shapes and sizes, and multi-point contact can provide better adaptability and fixing effect. The simultaneous action of the plurality of adaptive abutting units 7 can reduce the error accumulation that may be generated by a single unit during positioning, thereby improving the accuracy of overall positioning.
