specific Embodiment approach 1
[0008] Specific implementation mode one: combine Figure 1-Figure 13 Describe this embodiment, a stick-slip rotary positioning device, the device includes a rotating unit 1, a drive unit 2 and a base 3; the rotating unit 1 includes a first rotating semicircular table 1-1 and a second rotating semicircular table 1-2 , the driving unit 2 includes a driving elastic table 2-1 and a driving rotating plate 2-2, the base 3 includes a base 3-1 and a piezoelectric ceramic driver 3-2, and the center of the section of the first rotating semicircular table 1-1 is processed with The first V-shaped groove 1-5, the second V-shaped groove 1-6 is processed at the center of the cross section of the second rotating semi-circular platform 1-2, the first rotating semi-circular platform 1-1 and the second rotating semi-circular platform 1-2 are opposite The installation combination is a round table, the first V-shaped groove 1-5 and the second V-shaped groove 1-6 are arranged oppositely, the drivin...
specific Embodiment approach 2
[0011] Specific implementation mode two: combination figure 1 , figure 2 and Figure 8 Describe this embodiment, a stick-slip type rotary positioning device, the first rotary semicircular table 1-1 is processed with two countersunk holes 1-7, the center line of the counterbore 1-7 is aligned with the first rotary semicircular table The straight face on one side of 1-1 is vertical, and two first threaded holes 1-8 are provided on the second rotating semicircular table 1-2, and the two first threaded holes 1-8 are opposite to the two countersunk holes 1-7 The settings are the same as those in the first embodiment.
specific Embodiment approach 3
[0012] Specific implementation mode three: combination figure 1 , figure 2 and Figure 8 Describe this embodiment, a stick-slip rotary positioning device, the device also includes two first adjusting bolts 1-3 and two adjusting springs 1-4, the adjusting springs 1-4 are sleeved on the first adjusting bolts 1- 3 on the screw rod, the adjustment spring 1-4 is installed in the first threaded hole 1-8 through the countersunk hole 1-7, and the two semicircular bodies can be effectively fixed by the adjustment spring 1-4 and the first adjustment bolt 1-3 screw rod, This method can precisely adjust the frictional force between the rotating unit 1 and the rotating shaft 2-1-2 to make the structure compact, and the other is the same as the second embodiment.
