Description

Technical Field

[0001] The utility model relates to the technical field of cylinder end covers, and specifically relates to an end cover assembly for a precision cylinder device. Background Technique

[0002] A cylinder is a common mechanical component that can convert the pressure of gas or liquid into mechanical energy to drive the movement of machines and equipment. The cylinder end cover is one of the components of the cylinder equipment. Its main function is to seal the cylinder to prevent air leakage and the entry of external impurities. At the same time, it is also an important part connecting the cylinder and the piston. Due to the long-term action of hydraulic shock and working load, the cylinder end cover is very easy to be damaged and needs to be replaced in time. However, the current cylinder end covers still have the following deficiencies:

[0003] For example, the patent document with the application number 202123052330.X discloses an end cover for a cylinder. In this end cover for a cylinder, through holes are provided on the end cover, and the residual gas in the cylinder barrel can be conveniently discharged through the through holes to prevent the end cover from detaching from the cylinder barrel or cracking under the action of the expansion force of the residual gas, thereby ensuring the normal operation of the cylinder and extending the service life of the cylinder. However, its installation steps are relatively cumbersome, the installation efficiency is low, and the installation is not firm enough.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and an end cover assembly for a precision cylinder device is proposed. Summary of the Invention

[0005] The purpose of the utility model is to provide an end cover assembly for a precision cylinder device to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An end cover assembly for a precision cylinder device includes a main cover body and an installation assembly. The main cover body is a steel structure formed by integral molding. The installation assembly is arranged on the surface of the main cover body, and the installation assembly includes a fixed installation groove, an installation positioning groove, a threaded installation groove, a limit fixing hole, and an internal thread sealing cover. The fixed installation groove is opened on the front surface of the main cover body, and an installation positioning groove is opened on the rear surface inside the fixed installation groove. A threaded installation groove is opened on the front surface of the main cover body, and a limit fixing hole is opened on the rear surface of the main cover body. The front end of the limit fixing hole penetrates through the rear surface of the threaded installation groove, and four groups of the threaded installation groove and the limit fixing hole are correspondingly arranged. The rear surface of the limit fixing hole is snap-fitted with an internal thread sealing cover.

[0007] Further, two groups of the installation positioning grooves are symmetrically arranged, and a magnetic adsorption layer is arranged on the inner surface of the installation positioning groove.

[0008] Further, a limit cylinder is arranged on the surface of the main cover body, and a sealing assembly for improving the sealing performance is arranged inside the limit cylinder.

[0009] Further, the sealing assembly includes a threaded fixing rod, a rubber sealing plug, and a waterproof sealing gasket. The threaded fixing rod is threadedly connected to the inner side of the limiting cylinder. A rubber sealing plug is arranged at the bottom of the threaded fixing rod, and a waterproof sealing gasket is arranged on the inner surface of the threaded installation groove.

[0010] Further, the sealing assembly further includes an elastic sealing ring and a polyurethane waterproof film. An elastic sealing ring is connected to the front end of the inner surface of the fixed installation groove, and a polyurethane waterproof film is arranged at the rear end of the inner surface of the fixed installation groove.

[0011] Further, an exhaust channel is formed on the upper surface of the inner side of the fixed installation groove, and the output end of the exhaust channel is connected to the lower surface of the limiting cylinder.

[0012] Further, the lower end of the inner side of the exhaust channel is snap-fitted with the rubber sealing plug, and the upper end of the inner side of the exhaust channel is threadedly connected to the threaded fixing rod.

[0013] Further, a PVD hard coating is arranged on the outer surface of the main cover body, and a hard steel support layer is arranged inside the main cover body.

[0014] The utility model provides a precision cylinder equipment end cover assembly, which has the following beneficial effects:

[0015] 1. By providing an installation assembly, the installation assembly includes a fixed installation groove, an installation positioning groove, a threaded installation groove, a limit fixing hole, and an internal thread sealing cover. During use, the installation of the end cover is positioned through the installation positioning groove, improving the accuracy of installation docking. After positioning, through the snap-fitting connection with the fixed installation groove, preliminary fixation is achieved. Then, the installation rod of the cylinder is threadedly connected to the threaded installation groove until the rear end of the installation rod penetrates into the inner side of the limit fixing hole. The internal thread sealing cover is threadedly connected to the rear end of the installation rod until the outer side of the internal thread sealing cover is completely snap-fitted with the inner side of the limit fixing hole. Thus, the rapid installation of the end cover and the cylinder equipment can be realized, improving the installation efficiency, and the installation is stable and not prone to loosening.

[0016] 2. By providing a sealing assembly, the sealing assembly includes a threaded fixing rod, a rubber sealing plug, and a waterproof sealing gasket. The sealing assembly further includes an elastic sealing ring and a polyurethane waterproof film. During use, the threaded fixing rod is screwed downward along the inner surface of the limiting cylinder, so that the threaded fixing rod drives the rubber sealing plug to move downward along the inner side of the limiting cylinder into the exhaust channel until the rubber sealing plug is tightly connected to the lower end of the inner side of the exhaust channel, sealing the exhaust channel by the rubber sealing plug. The waterproof sealing gasket can improve the waterproof sealing performance between the installation rod and the threaded installation groove. The elastic sealing ring can improve the sealing performance of the fixed installation groove, and the polyurethane waterproof film can enhance the waterproof effect. Thus, the overall sealing performance of the device is strong, preventing internal water ingress and corrosion. Description of the Drawings
