Problems solved by technology

[0002] Generally, the cylinder is only a single stroke when it is running. The range of use of this cylinder is relatively single. If the inside of the cylinder is worn, it will lead to insufficient precision of the cylinder operation.
At present, in order to solve this problem, a positioner is added to the actuator on the cylinder, and the positioner controls the pressure of the air source input to the actuator to control the stroke of the cylinder. However, the control of the stroke of the cylinder requires circuit control, which is costly and complicated. The accuracy of the control process also needs to be improved

Embodiment Construction

[0018] The features and principles of the present invention will be described in detail below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, not to limit the protection scope of the present invention.

[0019] Such as figure 1 with figure 2 As shown, this embodiment provides a cylinder, including a cavity 1, a first end cover 2 and a second end cover 3 disposed at both ends of the cavity 1, a solenoid valve (not shown) disposed on the cavity 1, And the piston 4 that is arranged in the cavity 1 and divides the cavity 1 into an air inlet chamber and an air outlet chamber, at least one of the first end cover 2 and the second end cover 3 is provided with a piston 4 for adjusting The adjustment structure of the movement stroke.

[0020] The setting of the adjustment structure realizes the adjustment of the stroke of the piston 4, and when the cylinder is worn, the cylinder stroke can be changed so that the cy...

Abstract

The invention relates to a cylinder comprises a cavity, a first end cover and a second end cover which are arranged at two ends of the cavity, an electromagnetic valve arranged on the cavity and a piston which is arranged in the cavity and which divides the cavity into a gas incoming cavity and an exhausting cavity. At least one of the first end cover and the second end cover is provided with an adjusting structure used for adjusting the moving stroke of the adjusting piston. The cylinder has the advantages that the piston stroke is adjustable through the adjusting structure, when the cylinder is worn, the cylinder can be used continuously by changing the cylinder stroke.

Description

technical field [0001] The invention relates to the mechanical field, in particular to an air cylinder. Background technique [0002] Generally, the cylinder is only a single stroke in operation, and the scope of use of this cylinder is relatively single. If there is wear and tear inside the cylinder, the accuracy of the operation of the cylinder will not be sufficient. At present, in order to solve this problem, a positioner is added to the actuator on the cylinder, and the positioner controls the pressure of the air source input to the actuator to control the stroke of the cylinder. However, the control of the stroke of the cylinder requires circuit control, which is costly and complicated. The accuracy of the control process also needs to be improved. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a cylinder, which improves the structure of the cylinder and achieves the purpose of controlling the stroke...
