Abstract

The invention discloses a piston type oscillating cylinder which comprises a cylinder body, rack-shaped piston rods, adjusting screw rods and an output shaft. The cylinder body is provided with two cylinder chambers and two end covers. The two rack-shaped piston rods are arranged in the two cylinder chambers respectively. The two adjusting screw rods are arranged on one end cover. The output shaft is fixedly provided with a gear which is in meshed connection with the two rack-shaped piston rods. The output shaft is connected with a rotary disk. The end cover where the adjusting screw rods are placed is a gas inlet end cover, and the other end cover is a gas outlet end cover. Each adjusting screw rod is provided with a gas inlet hole and a gas inlet adjusting mechanism. Each rack-shaped piston rod is provided with a vent hole. The gas outlet end cover is provided with two exhaust holes and two exhaust adjusting mechanisms which correspond to the two cylinder chambers respectively. According to the piston type oscillating cylinder, the rack-shaped piston rods are provided with the vent holes so that gas can flow to the other end from one end of each cylinder chamber, a buffer effect is achieved on the movement of the rack-shaped piston rods, the movement of the rack-shaped piston rods is stable and collision force is reduced.

Description

technical field [0001] The invention relates to the field of oscillating cylinders, in particular to a piston-type oscillating cylinder. Background technique [0002] Piston swing cylinder is a pneumatic actuator that uses the piston rod of one or two cylinders to drive the output shaft to make reciprocating rotary motion within a certain angle range. It is widely used in the indexing, flipping, sorting, clamping, valve The opening and closing of the robot and the arm movement of the robot, etc. The piston rod of the existing piston-type oscillating cylinder is cylindrical, and the piston rod of the cylinder is made into a rack shape by uniformly processing a number of teeth along the axial direction in the middle of the cylindrical surface of the piston rod. The rod rotates in mesh with a gear fixed on the output shaft to convert the linear motion of the piston rod of the cylinder into the rotation of the output shaft. After the cylinder is inhaled, the piston rod is dire...
