Description

Auxiliary device for assembling plug

The technical field is as follows:

the utility model belongs to the technical field of precision machinery, specifically provide an auxiliary device for end cap assembly.

Background art:

the assembly of the shell plug is the first key process of the assembly of various shells and is a key component for realizing oil circuit control of hydraulic products. The quality requirement precision is high during the assembly, and the low quality of end cap assembly can directly influence the performance of hydraulic products, even cause waste, still can influence the delivery node of product. The current plug assembly mainly has two defects: firstly, as the plug part is small, the punching pressure required by the punching of the plug is large, and the punch easily falls off the hand, the shell is damaged, and the operator is injured; and two persons are needed to cooperate for preventing hands from falling off, so that the number of the required assembling personnel is increased.

The utility model has the following contents:

the utility model aims at: the utility model discloses based on end cap installation angle, a simple structure, convenient to use's end cap assembly auxiliary device is provided.

The technical scheme of the utility model: an auxiliary device for assembling a plug is formed by integrally forming a square cover plate and a circular boss, wherein the square cover plate is provided with symmetrical punch holes, and the end surface of the square cover plate is also provided with a positioning hole; the center of the whole device is provided with a through hole.

When the device is used, the circular truncated cone part is arranged in a hole of a main control valve shell, the punch hole is aligned with the plug hole, the four screws are used for fixing the position to prevent sliding, the punch stretches into the punch hole of the device for plug installation, and the problems that the punch slides and falls off hands in the striking process are avoided.

The automatic guide drift is accurate to be adjusted well main control valve end cap mounting hole, prevents to punch in-process drift slippage, causes product unnecessary damage and operating personnel injured. The symmetrical design of the punch holes enhances the universality of the device, can be used for installing the plug at the other side of the shell, reduces the use of tools and reduces the cost.

The utility model discloses novel structure, the principle is simple, and convenient to use can satisfy different positions end cap installation moreover, and whole end cap installation process is controlled easily, has effectively solved the injured problem of master control valve casing and operating personnel in the end cap installation, alleviates operating personnel's burden, has reduced operating personnel's outfit, has reduced manufacturing cost.

FIG. 2 is a schematic view of plug assembly

In the figure: 1-auxiliary device for assembling plug, 2-main control valve shell, 3-plug core, 4-plug cup

Detailed Description

It is right to combine below attached structure diagram the utility model relates to a structure theory of operation and embodiment for end cap assembly auxiliary device carry out detailed description, but structure theory of operation schematic diagram and embodiment do not be used for the restriction the utility model discloses, the fan adopts the utility model discloses a location, installation isotructure and principle all should belong to the utility model discloses a protection scope.

Example 1

Specifically as shown in fig. 1, the utility model discloses a be used for end cap assembly auxiliary device is a whole stainless steel part, including the punch hole of sealed rubber ring groove, longitudinal symmetry, terminal surface have screw hole, the center of location usefulness to open there are flexible pole clearing hole, main control valve locking gasket mounting groove etc.. On the basis of the design of above-mentioned structure, the utility model discloses in concrete design process, can also do following improvement, it is specific:

the plug assembly auxiliary device is integrally formed and made of high-strength steel. A rubber pad is arranged at the contact part of the device and the upper surface of the shell.

When assembling, the contact part of the rubber ring and the inner hole of the shell is provided with the rubber ring. The side surface of the circular boss of the device is provided with a groove. The square apron four corners of device sets up the chamfer, prevents to hinder the people, and 2 are no less than to the screw hole, and is optimum 4, and the location is firm, prevents to slide and rotates.

Taking 4 screw holes as an example, and a specific using method is as illustrated in fig. 2, the utility model discloses a specific application example, with 1-end cap assembly device round platform end down, a drift hole aligns 2-the end cap hole of master control valve case and installs, then place 3-stifled core in 4-stifled cup, and place in the casing is downthehole together, put the drift into the drift hole of 1-end cap assembly device, use the hammer to strike the drift, avoided the drift to slide, effectively solved the problem that the drift broke away in the punching process.
