Description

Technical Field

[0001] The utility model relates to the technical field of high-precision cylinder production, in particular to a cylinder body installation structure. Background Art

[0002] The cylinder is a cylindrical metal part that guides the piston to perform linear reciprocating motion in the cylinder. It is the most commonly used driving component in mechanical equipment.

[0003] According to the invention patent application with patent number: CN103851010A and publication date of 2014-06-11, a cylinder is disclosed, which includes a cylinder body, a piston assembly and a clamping assembly. The cylinder body is provided with a receiving cavity, and the cylinder body is provided with an air inlet and an air outlet communicating with the receiving cavity. The piston assembly is movably mounted in the receiving cavity, and the clamping assembly is movably mounted on the piston assembly. The piston assembly includes a piston, a guide rod and a limiting mechanism. The piston and the limiting mechanism are respectively fixedly mounted at both ends of the guide rod. The piston and the guide rod are partially slidably arranged in the receiving cavity of the cylinder body. The clamping assembly includes a push member, a pin and at least one engaging member. The push member is movably accommodated in the guide rod and moves within a certain range with the help of the limiting mechanism. The at least one engaging member is movably accommodated in the guide rod and abuts against one end of the push member so that the at least one engaging member partially protrudes out of the guide rod. Its main technical effect is: multiple engaging parts are accommodated in the limiting hole of the guide rod and are held against one end of the pushing part. Under the push of the air source, the guide rod pushes the pushing part, so that the pushing part pushes the multiple engaging parts, so that the multiple engaging parts protrude from the limiting hole and are held against the inner wall of the object. Since the multiple engaging parts are all accommodated in the guide rod, the volume of the cylinder is small and the structure is compact.

[0004] During the movement of the cylinder, the piston rod moves between the outside and the inside of the cylinder body. When moving, some of the external dust will be carried into the cylinder, resulting in a decrease in accuracy. Adding a dust cover on the outside can reduce the entry of dust. After a long period of activity, the dust cover will age and need to be replaced. Therefore, a cylinder body mounting structure is proposed, aiming to propose a structure that is convenient for replacing the cylinder body dust cover. Utility Model Content
