Description

Technical Field

[0001] The utility model relates to a cylinder pushing device, in particular to a single-rod non-rotating cylinder pushing device. Background Art

[0002] A cylinder is an actuator in a pneumatic system. It converts the energy of compressed air into mechanical energy to achieve linear motion or swinging. A cylinder usually consists of a cylinder barrel, a piston, a piston rod, a front end cover, a rear end cover and seals, etc., and has wide applications in the fields of industrial automation, mechanical manufacturing, automobile manufacturing, etc.

[0003] When a cylinder pushes a part or a device to move, in order to solve the problem of the rotation of the cylinder shaft, circular guide rods are usually symmetrically arranged on both sides of the cylinder to prevent the cylinder from rotating. However, for this pushing device with two circular guide rods, since the cylinder shaft needs to cooperate with the guide rods, it is difficult to release the fitting tolerance, the machining and manufacturing precision requirements are high, and the situation that the guide rods and the cylinder rod are in conflict with each other is likely to occur, which is easy to damage the cylinder and has poor durability. Similar problems also exist in the existing finished three-guide-rod cylinders. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the technical problems of the existing cylinder pushing device with two circular guide rods, which has difficult release of fitting tolerance due to the need for the cylinder shaft to cooperate with the guide rods, high machining and manufacturing precision requirements, easy occurrence of the situation that the guide rods and the cylinder rod are in conflict with each other, easy damage to the cylinder and poor durability, and to provide a single-rod non-rotating cylinder pushing device.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] It includes a mounting frame, a cylinder and a guide rod;

[0008] There is one guide rod; the mounting frame is mounted on the ground or an external mounting mechanism;

[0009] The cylinder is mounted on the mounting frame, and its output end is connected to an external device to be pushed;

[0010] One end of the guide rod is mounted on the external device, and the other end passes through the mounting frame and is in sliding fit with it;

[0011] The length direction of the guide rod is arranged parallel to the output direction of the cylinder.

[0012] Further, the cross-section of the guide rod is rectangular.

[0013] Further, a guide sleeve is provided on the mounting bracket, and a guide hole adapted to the guide rod is provided on the guide sleeve. The other end of the guide rod passes through the guide hole to achieve sliding cooperation with the mounting bracket.

[0014] Further, the mounting bracket includes a mounting plate and two mounting sub - brackets respectively mounted at both ends of the mounting plate;

[0015] The cylinder is mounted on the mounting plate, the guide sleeve is provided on the mounting plate, and a through - hole corresponding to and communicating with the guide hole is provided on the mounting plate at the position of the guide sleeve. The other end of the guide rod passes through the guide hole and the through - hole;

[0016] The two mounting sub - brackets are respectively mounted on the ground or an external mounting mechanism.

[0017] Further, the two mounting sub - brackets have the same structure and are arranged in parallel. Each of them includes a first connecting rod and two second connecting rods respectively connected to both ends of the first connecting rod;

[0018] The length directions of the first connecting rod and the second connecting rod are perpendicular to each other, and both ends of the mounting plate are respectively connected to the closer sides of the two first connecting rods;

[0019] The other ends of the two second connecting rods are respectively mounted on the ground or an external mounting mechanism.

[0020] Further, one long side of the rectangle is adjacent to and corresponds to the cylinder, that is, the axis of the output end of the cylinder is located in the plane of the mid - plane perpendicular to this long side in the guide rod.

[0021] Further, the guide sleeve is made of wear - resistant plastic.

[0022] Further, a cylinder head cap is provided on the output end of the cylinder, and the output end of the cylinder is connected to an external device through the cylinder head cap.

[0023] The beneficial effects of the present utility model are as follows:

[0024] 1. The present utility model only sets one guide rod. Compared with setting two guide rods, the requirement for machining accuracy is reduced, which ensures the cooperation between the guide block and the guide rod, avoids the situation that the guide rod and the cylinder compete with each other, thus damaging the cylinder, and improves the durability.

[0025] 2. Compared with the existing circular guide rod, the cross - section of the guide rod in the present utility model is set as a rectangle, which increases the contact area of the guide and improves the force condition, further ensuring the cooperation between the guide block and the guide rod.

[0026] 3. In the present utility model, the long side of the rectangular cross-section of the guiding rod is arranged corresponding to the setting direction of the air cylinder and adjacent to it, so that the long side is the stress direction, increasing the dimension in the stress direction, thereby further improving the stiffness in the stress direction.
