[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figure 1-8 A multi-station turntable circulation limiting structure includes a multi-station turntable body 1, a sliding groove 8 is opened at the bottom of the multi-station turntable body 1, and a limiting groove 9 is opened inside the sliding groove 8, and a mounting hole 3 is opened at the top of the multi-station turntable body 1;

[0027] A fixture 2 is installed inside the mounting hole 3 by fixing screws. A supporting structure 5 is provided at the bottom of the multi-station turntable body 1 . The supporting structure 5 is provided with a clamping groove 61 , and a limiting plate 6 is provided in the clamping groove 61 .

[0028] A support column 7 is provided on the top of the limiting plate 6 , an air inlet 71 is provided on the bottom of the supporting column 7 , and a limiting sleeve 72 is provided on the top of the supporting column 7 .

[0029] At the same time, a main controller 4 is provided on the side of the supporting structure 5 , and the pulse air pump 10 is connected to the main controller 4 via electrical signals.

[0030] In addition, a connection port 74 is provided at the top of one side of the support column 7 , and a telescopic rod 73 is provided inside the limiting sleeve 72 , and one end of the telescopic rod 73 is connected to a ventilation rod 76 .

[0031] Furthermore, a vent 75 is formed at the bottom of the vent rod 76 , and the vent 75 is communicated with the connecting port 74 . A through slot 78 is formed on the side of the vent rod 76 , and a telescopic rod 73 is slidably disposed in the through slot 78 .

[0032] At the same time, when the limiting sleeve 72 is extended through the telescopic rod 73, the limiting sleeve 72 and the limiting groove 9 are adapted to each other.

[0033] Moreover, a sealing piston 77 is provided inside the limiting sleeve 72 , and a sealing piston rod is provided around the sealing piston 77 , and the sealing piston rod is in compression contact with the telescopic rod 73 .

[0034] A pulse air pump 10 is provided on the side of the support structure 5 , and the output end of the pulse air pump 10 is connected to the air inlet 71 opened at the bottom of the support column 7 through a connecting air pipe 11 .

[0035] In this embodiment, the parts are first installed on the fixture 2 installed on the top of the multi-station turntable body 1, and after processing, the turntable needs to be rotated to adjust the station. Since the body is in a fixed state, it is first necessary to release the limit before it can be rotated.

[0036] First, retract the support column 7 at the bottom of the multi-station turntable body 1 so that the limit sleeve 72 on the top of the support column 7 is separated from the limit groove at the bottom of the multi-station turntable body 1. Then the multi-station turntable body 1 can be rotated. At this time, the driving motor inside the support structure 5 is controlled and the multi-station turntable body driven by it is rotated at a uniform angle each time according to the position of the clamp 2 installed on its top.

[0037] When the multi-station turntable body 1 rotates to the required station, the main controller 4 controls the pulse air pump 10 to connect to one side of the support column 7 through the connecting air pipe, and extends the limit sleeve 72 on the top of the support column to the limit groove 9 opened at the bottom of the multi-station turntable body 1. At this time, the gas is transported to the interior of the support column 7 through the output end of the pulse air pump 10, and then the gas flows to the interior of the ventilation rod 76 through the connecting port 74 on the top of the support column 7, and the sealing piston 77 in the telescopic rod 73 extends the movable part of the telescopic rod 73 through gas expansion, and then extends the telescopic rod 73 through the through groove 78, so that the limit sleeve 72 and the limit groove 9 are mutually locked, so that the multi-station turntable body 1 can be accurately limited.

[0038] In the present invention, a sliding groove 8 and a limiting groove 9 are opened at the bottom of the multi-station turntable body 1, and the limiting sleeve 72 on the top of the support column 7 on the limiting plate 6 installed on the side of the support structure 5 is clamped, and after the multi-station turntable body 1 is rotated, the movable part in the telescopic rod 73 can be ventilated to clamp the limiting sleeve 72 and the limiting groove 9 to each other, so that the multi-station turntable body 1 can be accurately limited after rotation.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
