[0029] Several positioning mechanisms 4 are distributed along the rotation center of the rotary mechanism 5. The positioning mechanism 4 includes a positioning hole or positioning groove adapted to the guide section 301. The positioning mechanism 4 can be a separate part or can be directly processed on the rotary mechanism 5. Figure 4 As shown, the positioning mechanism 4 is a positioning groove directly processed on the rotary mechanism 5.

[0030] In this embodiment, the positioning mechanism 4 includes a positioning sleeve 401 , and a positioning hole or a positioning groove adapted to the guiding section 301 is provided in the positioning sleeve 401 .

[0031] The positioning hole or positioning groove is a conical hole or a V-shaped hole, such as Figures 5-6 As shown, the guiding section 301 is a frustum or V-shaped structure adapted to the positioning hole or positioning groove.

[0032] The rotary mechanism 5 is a rotary body that rotates around the center and can be a circular structure, such as Figure 3 and 4 As shown, the rotary mechanism 5 can also be a polygonal structure or a spoke-shaped radial structure. The positioning mechanism 4 is distributed on the rotary mechanism 5 or on the outer circumference of the rotary mechanism 5.

[0033] The center line of the hole of the positioning sleeve 401 is generally arranged perpendicular to the rotating surface, and can also be arranged parallel to it.

[0034] The pushing mechanism 2 is a pneumatic cylinder, hydraulic cylinder, or electric push rod. It controls the linear motion of the guide pin 3. One end is connected to the guide pin 3, and the other end is connected to the frame 1. The pushing mechanism 2 can be a pneumatic device, an electric device, or other linear motion mechanism.

[0035] In this embodiment, a cylinder is used as the pushing mechanism 2. The pushing mechanism 2 is vertically arranged, and a mounting hole is provided on the rotary mechanism 5 to match the positioning sleeve 401. The positioning sleeve 401 is vertically arranged.

[0036] The rack 1 is provided with a pin sliding seat 7, and the guide pin 3 comprises a positioning sliding rail segment 302 matched with the pin sliding seat 7. The control surface of the pin sliding seat 7 in contact with the positioning sliding rail segment 302 is matched with the positioning sliding rail segment 302, which can be a cylindrical hole structure, a "T" type slot structure, or a "dovetail slot" structure.

[0037] By matching the pin sliding seat 7 with the guide pin 3, the freedom of the guide pin 3 is controlled, so that the guide pin 3 can only move freely in one direction.

[0038] Preferably, the end of the guide pin 3 connected with the pushing mechanism 2 is provided with a connecting lug seat 303, and the connecting lug seat 303 is connected with the telescopic end of the pushing mechanism 2 through a bolt or a pin, so as to realize the connection of the guide pin 3 with the pushing mechanism 2 and facilitate disassembly.

The proximity switch is electrically connected with the controller of the rotating mechanism 5, and the controller provides control instructions for the rotating mechanism 5 through the switch signal of the proximity switch.

[0042] Different from embodiment 1, as shown in Figure 7 and 8 , the pushing mechanism 2 is horizontally arranged, the bottom of the rotating mechanism 5 is provided with a plurality of mounting frames 6, and the mounting frames 6 are provided with horizontally arranged positioning sleeves 401.

[0043] The guide pin 3 is pushed out by the pushing mechanism 2 and inserted into the corresponding positioning sleeve 401, so as to guide the rotating mechanism 5.

[0044] The working principle of the device is as follows: after the rotating mechanism 5 is rotated to a set angle and stops rotating, the guide pin 3 is actuated under the action of the pushing mechanism 2 and is inserted into the sleeve hole of the corresponding positioning sleeve 4. Due to the cooperation and extrusion force between the sleeve hole of the positioning sleeve 4 and the tapered surface of the guide segment 301, the rotating mechanism 5 is rotated and driven, the gap between the tapered surfaces is eliminated, the guiding and positioning are realized, and the rotating mechanism 5 is locked by the insertion of the guide pin 3 into the sleeve hole of the positioning sleeve 401, so as to limit the further rotation of the rotating mechanism 5. When the rotating mechanism 5 needs to be rotated to the next station, the pushing mechanism 2 is retracted, the guide pin 3 is separated from the positioning sleeve 401, and the rotating mechanism 5 continues to work and rotates to the next station.
