Embodiment Construction

[0014] See attached figure 2 , a tool for fast and precise installation and disassembly of valve sleeves, consisting of a first pin 1, a second pin 2, a housing 3, a mandrel 4, and an elastic collet 5; the first pin 1 is fixedly connected to the mandrel 4 Form the first handle, turn the first handle, and the mandrel rotates thereupon; the second pin 2 is fixedly connected with the housing 3 to form the second handle, hold the second handle tightly, and the whole device can be picked up or put down; the collet 5 is threaded and The shell 3 is connected as a whole, and the front end of the collet 5 is set in the form of a gap; the mandrel 4 is threadedly matched with the shell 3 and passes through the center hole of the collet 5. When the mandrel 4 rotates, due to the effect of the thread , the mandrel 4 will move back and forth in the shell and the collet. When the mandrel moves forward, the collet will expand under the action of the mandrel; conversely, when the mandrel moves...

Abstract

The invention belongs to the technical field of assembling tools and particularly relates to a tool used for fast and accurately installing and disassembling a valve sleeve. The tool used for fast andaccurately installing and disassembling the valve sleeve is composed of a first pin 1, a second pin 2, a shell 3, a mandrel 4 and an elastic chuck 5; the first pin 1 and the mandrel 4 are fixedly connected to form a first handle, and by rotating the first handle, the mandrel rotates accordingly; the second pin 2 and the shell 3 are fixedly connected to form a second handle, and by holding the second handle, the whole device can be taken up or put down; the elastic chuck 5 and the shell 3 are connected into a whole through a thread, and the front end of the elastic chuck 5 is arranged into a manner of a notch; the mandrel 4 is matched with the shell 3 through the thread, and penetrates through a center hole of the elastic chuck 5; when the mandrel 4 rotates, due to the effect of the thread, the mandrel 4 moves forwards and backwards in the shell and the elastic chuck; when the mandrel moves forwards, the elastic chuck expands under the expanding effect of the mandrel; and otherwise, when the mandrel moves backwards, the elastic chuck restores to be shrunk under the effect of the elasticity of the elastic chuck.

Description

technical field [0001] The invention belongs to the technical field of assembly tool design, and in particular relates to a tool for fast and accurate installation and disassembly of valve sleeves. Background technique [0002] The valve sleeve is an important part of the valve, usually installed in the elongated cylindrical hole of the housing (see figure 1 ). Although the valve sleeve and the housing are in clearance fit, the clearance is very small. When it is assembled with the sealing ring into a valve sleeve assembly and then put into the housing, the two become interference fit. And because the installation hole is deep and the valve sleeve is small, it is very difficult to install and disassemble only by hands, often resulting in low installation accuracy, jamming, or inability to disassemble, and installation and disassembly take a lot of time. In order to solve these problems, the tool for quickly and accurately installing and removing the valve sleeve is designe...
