Technical Field
[0001] This utility model relates to the field of rotary cylinders, and in particular to an adjustable rotary cylinder. Background Technology
[0002] A rotary cylinder is an actuator that converts gas pressure into rotary motion. Commonly used in industrial automation systems, its basic structure includes a cylinder body, piston, seals, bearings, and a rotating shaft. It utilizes the energy of compressed air to drive a rotary mechanism through the reciprocating motion of the piston within the cylinder, achieving continuous or intermittent rotation. Suitable for various applications requiring rotary motion, such as clamping, indexing, and driving rotary tables, it is ideal for applications requiring rotary motion, including clamping, indexing, and driving rotary tables.
[0003] Patent CN203670339U discloses a rotary cylinder. The rotating device includes a central wheel located in the middle of the cylinder body and racks located on both sides inside the cylinder body that mesh with the central wheel. One side of each rack is connected to the rear end cover of the cylinder body. A set of air passages is symmetrically arranged on both sides of the central wheel. The air inlet of the air passage is located on the rear end cover of the cylinder body. The upper part of the central wheel extends out of the cylinder body through the upper surface of the cylinder body. A square pin is cut on the inner wall of the connection between the central wheel and the rotating shaft. The central wheel drives the rotating shaft to rotate through the square pin and outputs power outward. However, when using this rotary cylinder, it usually requires manual operation of the threaded rod and nut to adjust the rotary cylinder. The adjustment speed is slow and it is inconvenient to use.
