Technical Field

[0001] The utility model relates to a cylinder, in particular to a double-acting composite cylinder, belonging to the technical field of cylinders. Background Art

[0002] A cylinder is a cylindrical metal part that guides a piston to perform linear reciprocating motion in the cylinder. Its working principle is mainly to increase the air pressure through the piston. The pneumatic transmission converts the pressure of the compressed air into mechanical energy, thereby driving the mechanism to perform linear reciprocating motion, or swing and rotation motion. The application fields of cylinders are very wide, such as printing, semiconductors, automatic control, robots, etc.

[0003] When the cylinder is in use, if you want to achieve movement in two different directions, you need to combine the two cylinders together, which will lead to a high manufacturing cost of the equipment. At the same time, the overall volume of the equipment is large after the combination, which cannot meet the use requirements of a small installation space. For this reason, a double-acting composite cylinder is proposed. Utility Model Content

[0028] In this embodiment, specifically: the outer side walls of the first piston 23 and the second piston 26 are both fixedly connected with sealing rings 29, and the sealing rings 29 play a sealing role to prevent air leakage in the cylinder.

[0029] In this embodiment, specifically: a cover 210 is fixedly connected to the front surface of the sliding plate 21 , and the cover 210 is used to limit the stroke of the first piston 23 .

[0030] In this embodiment, specifically: two second buffer pads 211 are symmetrically fixedly connected to the front surface of the sliding plate 21 , and buffer pads are arranged in the front and rear directions of the sliding plate 21 to prevent the sliding plate 21 from hitting the base 11 .

The first air inlet 212 and the second air inlet 213 are respectively arranged at the two ends of the first cavity 22. When the first air inlet 212 or the second air inlet 213 takes in air, the gas enters from different sides of the first piston 23, so that the sliding plate 21 moves horizontally along the base 11, and air is delivered to the second cavity 25 through the third air inlet 214 to control the movement of the second piston 26 and the second piston rod 27, so that the second piston rod 27 moves in the vertical direction, thereby using one cylinder to achieve movement in two directions, reducing the manufacturing cost of the equipment, and at the same time, the overall volume is small, which can meet the use requirements of a narrow installation space.
