Description

Technical Field

[0001] The utility model relates to the technical field of oil cylinder head disassembly structures, and particularly relates to a disassembly structure of an oil cylinder head. Background Art

[0002] An oil cylinder is a hydraulic cylinder. A hydraulic cylinder is a linear motion actuator whose output force is proportional to the effective area of the piston and the pressure difference on both sides. Its function is to convert hydraulic energy into mechanical energy.

[0003] At present, it is rather inconvenient to install and disassemble an oil cylinder head, which increases the difficulty of overhauling the oil cylinder and replacing the hydraulic oil. Moreover, there is a lack of special tools for disassembling the oil cylinder head nowadays. Content of the Utility Model

[0004] Technical Problem to be Solved

[0005] In view of the above-mentioned drawbacks of the prior art, the utility model provides a disassembly structure of an oil cylinder head, which can effectively solve the problem that it is rather difficult to disassemble the oil cylinder head in the prior art.

[0006] Technical Solution

[0007] To achieve the above object, the utility model is realized through the following technical solutions:

[0008] The utility model provides a disassembly structure of an oil cylinder head, including an oil cylinder body. A gasket is fixed at the top end of the oil cylinder body, and a support cover is fixed at the top end of the gasket. The middle part of the top end of the oil cylinder body is fixed with an oil cylinder head. An intermediate ring is sleeved outside the oil cylinder head. A jack is fixed at the top end of the support cover. Two groups of round holes are opened at the top end of the support cover, and bolt pull rods are arranged in the round holes. The bottom end of the bolt pull rod is arranged at the top end of the oil cylinder body, and its top end penetrates through the jack.

[0009] Further, a nut is sleeved outside the bottom end of each bolt pull rod, and the intermediate ring is clamped between the nut and the oil cylinder body.

[0010] Further, the top end of the bolt pull rod is tightly connected with the jack through a locking nut.

[0011] Further, the support cover is a hollow cavity structure with a small top end, a large bottom end and no bottom surface.

[0012] Further, the cross section of the gasket is an L-shaped structure. A groove structure with a diameter larger than the inner diameter and smaller than the outer diameter is opened inward at the bottom end of the gasket, and the size of the groove is adapted to the size of the top end of the oil cylinder body.

[0013] Furthermore, a frustum structure is provided at the top of the cylinder head, and the outer diameter of the frustum structure is consistent with the distance between the two sets of bolt tie rods.

[0014] Advantages

[0015] The technical solution provided by the present utility model has the following advantages compared with the known public technology:

[0016] With the jack-bolt tie rod-intermediate ring-washer structure provided by the present utility model, during use, first place the washer, then place the intermediate ring, tighten the bolt tie rod, put on the support cover, install the jack, tighten the bolt, and the jack is driven to complete the disassembly of the cylinder head. According to requirements, a manual hydraulic pump or an electric hydraulic station can be configured. The washer can prevent damage to the cylinder body, and disassembling the intermediate ring protects the threads of the parts to be disassembled. If the force is less than a specific weight, the intermediate ring can be omitted and the threaded rod can be directly tightened. The orange part is the support cover, which plays a supporting role during disassembly. BRIEF DESCRIPTION OF THE DRAWINGS
