Disclosure of Invention
The utility model aims at providing an impel rotary device to the aforesaid that prior art exists not enoughly, it is little, convenient to use of not only working stroke, and rotate nimble, the precision is high.
In order to achieve the above purpose, the utility model discloses a propulsion rotating device, which comprises a fixed seat and a guide seat fixedly arranged in the fixed seat; the automatic adjusting device is characterized in that a rotating sleeve is arranged in a guide seat in a sliding manner, a limiting step matched with the guide seat is fixedly connected to the rear end of the rotating sleeve, the rotating sleeve is provided with an inner hole, the front end of a push rod is arranged in the inner hole in a sliding manner, two symmetrical and equidirectional spiral grooves are formed in the side wall of the middle part of the inner hole of the rotating sleeve, the push rod is provided with a radial pin hole, a cylindrical pin penetrates through the pin hole of the push rod, two ends of the cylindrical pin are arranged in the two spiral grooves of the rotating sleeve, and a compression spring is arranged in the inner hole in front of the front end of the push rod; the front end of the rotary sleeve is fixedly connected with a pressure plate.
When the device is used, the push rod and the rotary sleeve are pushed forwards, when the limiting step of the rotary sleeve abuts against the guide seat, the rotary sleeve does not move forwards any more, the push rod continues to move forwards and drives the cylindrical pin to move forwards along the two spiral grooves, and the cylindrical pin and the two spiral grooves interact with each other to ensure that the rotary sleeve can only rotate and drive the pressing plate to rotate outwards due to the fact that the rotary sleeve cannot move forwards, so that the requirements of working conditions can be met; the push rod is loosened, the rotating sleeve reversely rotates under the action of the compression spring and drives the pressing plate to rotate inwards, and the automatic resetting is realized, so that the rotating sleeve does not axially move during rotation, the working stroke is small, the required movable space is small, the use is convenient, the two ends of the cylindrical pin simultaneously push the rotating sleeve to rotate, the two sides of the rotating sleeve are stressed, the rotation is flexible, the loading is uniform, the abrasion is not easy to occur, the rotation precision is high, and the frequent replacement is not needed;
as a further improvement of the utility model, the inner circle of the front end of the guide seat is provided with a sealing ring; impurities can be prevented from entering, and the rotation flexibility of the rotary sleeve is ensured;
as a further improvement of the utility model, a radial oil cup is arranged on the guide seat at the rear side of the sealing ring; the inner circle of the guide seat can be lubricated and rustproof, so that the rotation flexibility is further improved;
to sum up, the utility model discloses not only the working stroke is little, convenient to use, and rotates nimble, the precision is high.
