[0029] Optionally, the top end of the positioning member 2 is provided with a guide slope 21, and the inner diameter of the workpiece is slightly larger than the outer diameter of the positioning member 2. In order to smoothly set the workpiece on the outer periphery of the positioning member 2, the top end of the positioning member 2 is provided with a guide slope 21, which can increase the gap between the outer wall of the top end of the positioning member 2 and the inner wall of the workpiece, and ensure that the positioning member 2 is smoothly inserted into the workpiece.
[0030] Optionally, the positioning device further comprises a plurality of protrusions, and the plurality of protrusions are arranged one by one corresponding to the plurality of positioning blocks 3. The plurality of protrusions are arranged at the other end of the positioning member 2 along the circumference of the positioning member 2, and the positioning block 3 is threadedly connected to the protrusion. Specifically, the plurality of protrusions are uniformly and spacedly arranged at the other end of the positioning member 2 along the circumference of the positioning member 2, and the positioning block 3 is slidably connected to the protrusion, so that the plurality of protrusions are uniformly distributed along the circumference of the positioning member 2, and the workpiece can be balanced in force, thereby further preventing the position of the workpiece from deviating.
[0031] Further, in the present embodiment, the positioning device is provided with three protrusions, which are uniformly and spacedly arranged at the end face of the positioning member 2 along the circumference of the positioning member 2. Specifically, the three protrusions are arranged on the same division circle and located at the 0° position, the 120° position and the 240° position of the division circle, respectively. Of course, in other embodiments, the number of protrusions is determined according to the actual situation, which will not be described here.
[0032] Optionally, the protrusion is integrally formed with the positioning member 2, which can improve the connection firmness of the protrusion and the positioning member 2, prevent the separation of the protrusion and the positioning member 2, and improve the service life of the positioning device.
[0033] Optionally, the side wall of the positioning member 2 is provided with a plurality of threaded holes 22, and the plurality of threaded holes 22 are arranged one by one corresponding to the plurality of positioning blocks 3. One end of the positioning block 3 can abut against the workpiece through the threaded hole 22, and the diameter of the threaded hole 22 is larger than that of the positioning block 3. Specifically, the protrusion is provided with the threaded hole 22, and the diameter of the threaded hole 22 is larger than that of the positioning block 3, so that the positioning member 2 can be applied to different types of positioning blocks 3, thereby providing different pressures and improving the versatility of the positioning device.

The shell is threadedly connected with the nut, the top bead is arranged in the interior of the shell, and part of the top bead is exposed to the shell. The two ends of the elastic member are connected with the top bead and the shell respectively. The elastic member always has a tendency to drive the top bead to be exposed to the shell, thereby making the top bead abut against the workpiece. When the external force is greater than the force of the elastic member, the workpiece can be rotated for position correction. When the external force is smaller than the force of the elastic member, the top bead is locked, thereby ensuring that the position of the workpiece will not deviate. Further, the elastic member is a compression spring.
