In some embodiments, referring to fig. 3, the groove 321 includes a first groove portion 3211, a second groove portion 3212, a third groove portion 3213, a fourth groove portion 3214, and a fifth groove portion 3215 that are sequentially connected, the extending directions of the first groove portion 3211 and the fourth groove portion 3214 are parallel to the axis of the rotating shaft 32, one end of the second groove portion 3212 is connected to a middle portion of the first groove portion 3211, an included angle between the extending direction of the second groove portion 3212 and the extending direction of the first groove portion 3211 is an acute angle, the other end of the second groove portion 3212 is connected to one end of the third groove portion 3213, the other end of the third groove portion 3213 is connected to a middle portion of the fourth groove portion 3214, an included angle between the extending direction of the third groove portion 3213 and the extending direction of the fourth groove portion 3214 is an acute angle, one end of the fifth groove portion 3215 is connected to one end of the first groove portion 3211 away from the second groove portion 3212, the other end of the fifth groove portion 3215 is connected to one end of the fourth groove portion 3214 near the driving member 10, and the first groove portion 1 extends in a smooth angle.

For ease of understanding, an end of the first groove portion 3211 in fig. 7, which is far from the driving member 10, is defined as an upper end, an end of the first groove portion, which is near to the driving member 10, is defined as a lower end, and the upper ends and the lower ends of the other groove portions in the present embodiment are defined as such, which is not described herein. Referring to fig. 5 and fig. 6 in combination, before the bearing assembly 40 rotates, the rotating shaft 32 approaches the driving member 10, and the balls 34 abut against the upper end of the first groove portion 3211. When the bearing assembly 40 is rotated, the driving member 10 drives the rotating shaft 32 to move away from the driving member 10, the first groove portion 3211 moves upwards relative to the balls 34, and when the joint between the second groove portion 3212 and the first groove portion 3211 moves to the position of the balls 34, the balls 34 move from the first groove portion 3211 to the second groove portion 3212. The driving element 10 drives the rotation shaft 32 to move away from the driving element 10, the balls 34 move from the second groove portion 3212 to the third groove portion 3213 and further abut against the lower end of the third groove portion 3213, and then the driving element 10 drives the rotation shaft 32 to move close to the driving element 10, so that the balls 34 move from the lower end of the third groove portion 3213 to the upper end of the third groove portion 3213, and the balls 34 move from the third groove portion 3213 to the upper end of the fourth groove portion 3214. At this time, the rotation shaft 32 is rotated by the guides of the second groove portion 3212, the third groove portion 3213, and the balls 34, and the rotation of the rotation shaft 32 is achieved from the rotation of the first groove portion 3211 corresponding to the balls 34 to the rotation of the second groove portion 3212 corresponding to the balls 34. When the rotation shaft 32 is reset, the driving member 10 drives the rotation shaft 32 to move away from the driving member 10, and the balls 34 move along the fourth groove portion 3214, further move to the fifth groove portion 3215, further move to the lower end of the fifth groove portion 3215, and then enter the lower end of the first groove portion 3211. After the balls 34 move to the lower end of the first groove portion 3211, the driving member 10 drives the rotating shaft 32 to move close to the driving member 10, so that the upper end of the first groove portion 3211 moves to a position corresponding to the balls 34, and the reset of the rotating shaft 32 is completed.

It can be appreciated that the rotation angle of the bearing assembly 40 driven by the rotation shaft 32 is equal to the central angle of the arc surface between the first groove portion 3211 and the second groove portion 3212.

Similarly, the extending direction of the fourth groove portion 3214 is parallel to the center line of the rotation shaft 32, and if the angle between the extending direction of the third groove portion 3213 and the extending direction of the fourth groove portion 3214 is greater than 45 degrees, that is, the angle between the extending direction of the third groove portion 3213 and the center line of the rotation shaft 32 is greater than 45 degrees, the balls 34 and Yi Ka are in the third groove portion 3213 during the rotation of the rotation shaft 32.

It will be appreciated that the rotation shaft 32 is moved away from the driving member 10, and is rotated under the guidance of the balls 34 and the grooves 321, and the rotation shaft 32 is moved close to the driving member 10 after being rotated by a certain angle. By arranging the upper positioning disk 43 and the lower positioning disk 44, the positioning block 431 of the upper positioning disk 43 and the positioning groove 441 of the lower positioning disk 44 can be utilized to fix the position of the connecting piece 41 after the rotation shaft 32 rotates, so that the position of the workpiece 200 is fixed, and the stability of the workpiece 200 during processing is improved.

When the third surface 203 and the fifth surface 205 of the workpiece 200 are required to be machined, the driving member 10 drives the rotating shaft 32 to move away from the driving member 10, and the rotating shaft 32 rotates under the guidance of the balls 34 and the grooves 321 during the movement.

The rotation process is approximately as follows: the rotation shaft 32 moves away from the driving member 10, the balls 34 move downwards relative to the first groove portion 3211 and then move into the second groove portion 3212, the rotation shaft 32 continues to move away from the driving member 10, meanwhile, rotation is conducted under the guidance of the second groove portion 3212 and the balls 34 until the third groove portion 3213 is shifted to the position of the balls 34, the third groove portion 3213 limits the rotation shaft 32 to continue to move away from the driving member 10, at this time, the driving member 10 drives the rotation shaft 32 to move close to the driving member 10, the rotation shaft 32 continues to rotate under the guidance of the third groove portion 3213 and the balls 34 until the fourth groove portion 3214 moves to the position of the balls 34, the rotation shaft 32 is not rotated any more, and the driving member 10 drives the rotation shaft 32 to continue to move close to the driving member 10 until the upper end of the fourth groove portion 3214 abuts against the balls 34, and rotation is completed. At this time, the third surface 203 and the fifth surface 205 of the workpiece 200 may be rotated by a certain angle, and then the third surface 203 and the fifth surface 205 may be rotated to the processing positions of the processing device in cooperation with the four-axis machine, so that the third surface 203 and the fifth surface 205 of the workpiece 200 may be processed by the processing device.

The reset process is roughly as follows: the driving member 10 drives the rotating shaft 32 to move away from the driving member 10, the balls 34 move downwards relative to the fourth groove portion 3214 and then enter the fifth groove portion 3215, the rotating shaft 32 rotates under the guidance of the fifth groove portion 3215 and the balls 34 until the first groove portion 3211 moves to the position of the balls 34, then the driving member 10 drives the rotating shaft 32 to move close to the driving member 10, and the balls 34 move upwards relative to the first groove portion 3211 until the balls abut against the upper end of the first groove portion 3211, namely resetting is completed.

When the rotating shaft 32 rotates, the upper positioning disc 43 and the lower positioning disc 44 can position the bearing assembly 40, so that the accuracy of positioning the workpiece 200 by the bearing assembly 40 is improved. Meanwhile, the connection member 41 can be buffered by the buffer member 22 during rotation. The positioning piece 42 is movably connected with the connecting piece 41, so that the positioning piece 42 corresponding to the workpiece 200 can be replaced for different types of workpieces 200, and the operation is convenient and the applicability is strong.
