Description

A tool for installation and removal of hydraulic skeleton

technical field

The application belongs to the technical field of assembly tools, and in particular relates to a tool for installing and dismounting a hydraulic framework.

Background technique

As an important part of the solenoid valve, the hydraulic skeleton is installed at 2 sealing end faces of the solenoid valve body (see Figure 1). The hydraulic framework 3 is threadedly connected to the solenoid valve body 1. When installing or dismounting in the traditional way, the slot on the hydraulic framework is clamped by the tightening head, and then the two are tightened or loosened.

Because the hydraulic frame is hollow inside, the contact area between the tightening head and the hydraulic frame is small, and the tightening torque between the hydraulic frame and the solenoid valve body is large, so it is very easy to cause the tool to slip when installing or removing the hydraulic frame, thereby scratching the operator's Hand or the sealing end face of the solenoid valve body, causing personal injury or product scrapping due to sealing failure.

Therefore, in order to solve these problems, the tool for installing and removing the hydraulic frame is designed.

A combined tightening head, including an adapter and a slotted head arranged on the adapter, the slotted head matches the slot of the hydraulic frame;

A protective sleeve, one end of the protective sleeve is sleeved on the adapter, and the other end is sleeved on the outer circle of the hydraulic frame, the protective sleeve is used to limit the position of the combined tightening head.

Preferably, the adapter is connected to the slotted head through an interference fit.

Preferably, the adapter is threadedly connected to the protective sleeve; wherein, one end of the adapter is provided with a thread, and the other end is provided with a clamping portion or a holding portion.

Preferably, the protective cover includes:

a threaded hole for connecting one end of the adapter;

The inner hole communicates with the threaded hole, and the inner hole can be sleeved on the outer circle of the hydraulic skeleton.

Preferably, the protective cover is made of non-metallic material.

Preferably, the protective sheath is made of polytetrafluoroethylene or plexiglass.

Beneficial technical effect of the application:

The tool itself provided by this application has the characteristics of simple structure and easy assembly. When in use, the protective cover acts as a limiter, which can completely avoid the problem of tool slippage during installation or disassembly of the hydraulic skeleton, thereby solving the problem of personnel injury or product failure during installation. The problem of scrapping due to seal failure caused by scratches; in addition, the combined tightening head can increase the number of uses and reduce the use cost of the entire tightening head.

Detailed ways

Please refer to Figures 1-4. The purpose of this application is to solve the problem that when installing or removing the hydraulic framework on the solenoid valve, the installation tool is very easy to slip, thereby scratching the operator's hand or the sealing end surface of the solenoid valve body.

In the embodiment of the present application, the present application adds a protective cover 6 to the tightening head composed of the adapter 4 and the slotted head 5 . The inner diameter of the protective sleeve 6 is slightly larger than the outer diameter of the hydraulic skeleton. When installing or disassembling the hydraulic skeleton, it can be conveniently set on the hydraulic skeleton to play a role in limiting the position. This can completely avoid the problem of tool slippage when the hydraulic skeleton is installed or removed. , so as to solve the problem of personnel being injured during installation or the product being scrapped due to seal failure caused by scratches.

Wherein, the protective sleeve 6 is assembled together with the screw thread and the tightening head, rather than the whole tool being processed as a whole, which greatly reduces the processing difficulty and saves the processing cost.

Wherein, the material of the protective cover 6 is soft non-metallic material such as polytetrafluoroethylene or plexiglass, which avoids damage to the hydraulic framework 3 when the protective cover 6 is in contact with the hydraulic framework 3 .

Among them, the integrated tightening head is changed into a combined tightening head, and the structure includes two parts-the adapter 4 and the slotted head 5, which are assembled together through interference fit. The combined structure makes it very easy to replace the slotted head 5 (wearing part) in the tightening head after being deformed or damaged after repeated use, prolonging the full-cycle service life of the entire tightening head.

Among them, the flat head 5 can have different specifications and sizes, and after being combined with the adapter 4 to form a tightening head, it can adapt to the installation requirements of hydraulic frameworks of different specifications and sizes.

Among them, the material of the inset 5 can be selected from spring steel with high strength such as Cr12MoV and 65Mn to increase the number of times of use, and the material of the adapter 4 can be selected from ordinary stainless steel such as 2Cr13 and 0Cr18Ni9 to reduce the material cost of the entire tightening head.

The application itself has the characteristics of simple structure and easy assembly; when in use, the protective cover 6 acts as a limiter, which can completely avoid the problem of tool slippage during installation or disassembly of the hydraulic skeleton, thereby solving the problem of personnel injury during installation or product damage due to scratches. The problem of scrapping due to seal failure caused by injury; the combined tightening head can increase the number of times of use and reduce the use cost of the entire tightening head.

In other embodiments of the present application, the technical solution is used to design and manufacture a tool for installing and dismounting the hydraulic framework. The adapter 4 forms a tightening head with the slotted head 5 through interference fit. The tightening head and the protective sleeve 6 are threaded to form a tool for installing and dismounting the hydraulic framework.

Further, the material of the adapter 4 is made of stainless steel such as 2Cr13, 0Cr18Ni9, the material of the prefix 5 is made of spring steel such as Cr12MoV, 65Mn, and the material of the protective cover 6 is made of non-metallic materials such as polytetrafluoroethylene or plexiglass.

The process of using this tool to install or disassemble the hydraulic frame is as follows: put the inner hole of the protective sleeve on the outer circle of the hydraulic frame, and install the tool on the hydraulic frame (Figure 3); turn the tool slightly, and insert the straight head of the tightening head into the slot of the hydraulic frame (Figure 4); turn the tool clockwise or counterclockwise again to tighten or loosen the hydraulic frame from the solenoid valve.
