Abstract
The utility model provides a compact swing hydraulic cylinder, including pneumatic cylinder, sharp uide bushing, spiral uide bushing, output shaft, swing arm, sharp uide pin, spiral uide pin. The hydraulic cylinder is a single-rod double-acting hydraulic cylinder. The linear guide sleeve is provided with a linear guide groove. The spiral guide sleeve is provided with a spiral guide groove. The linear guide pin fixed on the spiral guide sleeve is inserted into the linear guide groove of the linear guide sleeve. A spiral guide pin fixed on the output shaft is inserted into a spiral guide groove of the spiral guide sleeve. Due to the constraint effect of the guide groove on the guide pin, when the piston rod of the hydraulic cylinder stretches, the piston rod drives the spiral guide sleeve to move linearly and drives the output shaft to rotate so as to drive the swing arm to swing. The utility model discloses be fit for the application scenario that installation space is narrow and small, output torque is big.

Technical Field
The utility model relates to a compact swing hydraulic cylinder, the application scenario that the specially adapted installation space is narrow and small, output torque is big.
Background
Usually, the requirement of the mechanism action of the swing can be met by adopting a motor and a speed reducer, but compared with a hydraulic actuating element, the motor has the advantages of low power density, large volume and high cost of the speed reducer. Therefore, in applications requiring a large output torque and a small volume, a swing cylinder is generally used. The conventional swing hydraulic cylinder is two single-rod hydraulic cylinders which are symmetrically arranged, a rack is arranged in the middle of a piston rod, and the rack drives a gear to swing in a rotating mode. Due to the arrangement of the hydraulic cylinder, the gear and rack transmission mode and the like, the whole device is large in width and is not suitable for application fields with narrow installation space.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to the big problem of conventional swing pneumatic cylinder installation space, provide a compact swing pneumatic cylinder, the application that the specially adapted installation space is narrow and small, the output torque is big.
The technical scheme of the utility model:
a compact swing hydraulic cylinder comprises a hydraulic cylinder 1, a linear guide sleeve 2, a spiral guide sleeve 3, an output shaft 4, a swing arm 5, a linear guide pin 6 and a spiral guide pin 7; the hydraulic cylinder 1 is connected with the linear guide sleeve 2, the piston rod end of the hydraulic cylinder 1 is fixedly connected with the spiral guide sleeve 3, the spiral guide sleeve 3 is symmetrically provided with linear guide pins 6, the output shaft 4 is symmetrically provided with spiral guide pins 7, and the swing arm 5 is fixedly sleeved at the shaft end part of the output shaft 4; the linear guide sleeve 2 is provided with a linear guide groove; a spiral guide groove is formed on the spiral guide sleeve 3; a linear guide pin 6 fixed on the spiral guide sleeve 3 is inserted into a linear guide groove of the linear guide sleeve 2; a spiral guide pin 7 fixed to the output shaft 4 is inserted into a spiral guide groove of the spiral guide sleeve 3.
Further, the hydraulic cylinder 1 is a single-rod double-acting hydraulic cylinder.
Further, the piston rod end of the hydraulic cylinder 1 is connected with the spiral guide sleeve 3 in a locking mode through a second nut 10.
Further, the swing arm 5 is lockingly connected with the output shaft 4 through a first nut 9.
Further, the number of the linear guide pins 6 and the number of the spiral guide pins 7 are two.
The use method of the compact swing hydraulic cylinder is characterized in that a linear guide sleeve 2 is fixed, and a swing arm 5 is connected with an actuating mechanism; pressure oil is introduced into a rodless cavity or a rod cavity of the hydraulic cylinder 1, and a piston rod of the hydraulic cylinder 1 extends out or retracts due to the fact that the linear guide pin 6 is restrained by the linear guide groove of the linear guide sleeve 2, so that the spiral guide sleeve 3 is driven to do linear movement without rotating; because the spiral guide pin 7 is restrained by the spiral guide groove of the spiral guide sleeve 3, the output shaft 4 is driven to rotate by the linear movement of the spiral guide sleeve 3, and the swing arm 5 is driven to swing by the rotation of the output shaft 4.
The utility model has the advantages that: and a single-rod double-acting hydraulic cylinder is adopted, so that one hydraulic cylinder is reduced compared with a conventional swing hydraulic cylinder, and the composition is simplified. The hydraulic cylinder is longitudinally connected with the mechanical conversion device, and the whole device is small in outer diameter and suitable for narrow installation space. The linear guide sleeve, the spiral guide sleeve and the guide pin are adopted, power conversion of linear motion of the piston rod and swing of the swing arm is achieved, and the mechanical efficiency is high, the structure is simple, compact and reliable, and the cost is low.

In the figure: the hydraulic cylinder comprises a hydraulic cylinder 1, a linear guide sleeve 2, a spiral guide sleeve 3, an output shaft 4, a swing arm 5, a linear guide pin 6, a spiral guide pin 7, a bolt 8, a first nut 9 and a second nut 10.
Detailed Description
The present invention will be further described with reference to the following technical solutions and accompanying drawings.
In practical application, the linear guide sleeve 2 is fixed on the base, and the swing arm 5 is connected with the actuating mechanism through the head pin hole. The rodless cavity of the hydraulic cylinder 1 is communicated with pressure oil, the linear guide pin 6 is constrained by the linear guide groove of the linear guide sleeve 2, the piston rod of the hydraulic cylinder 1 extends out to drive the spiral guide sleeve 3 to move linearly leftwards without rotating, the spiral guide pin 7 is constrained by the spiral guide groove of the spiral guide sleeve 3, the leftward linear movement of the spiral guide sleeve 3 drives the output shaft 4 to rotate clockwise, and the rotation of the output shaft 4 drives the swing arm 5 to swing clockwise. The rod cavity of the hydraulic cylinder 1 is communicated with pressure oil, the piston rod of the hydraulic cylinder 1 retracts to drive the spiral guide sleeve 3 to move straightly rightwards without rotating, the straight moving rightwards of the spiral guide sleeve 3 drives the output shaft 4 to rotate anticlockwise, and the rotation of the output shaft 4 drives the swing arm 5 to swing anticlockwise.
