Detailed Description

Preferred embodiments of the present utility model are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present utility model, and are not intended to limit the scope of the present utility model.

The utility model provides a tool for machining the outer wall surface of a sliding valve sleeve 9, which comprises a bottom plate 1, a vertical plate 2 vertically fixed on the bottom plate 1, a mounting tube, a pull rod, a pressing block 6 and a handle 8. The base plate 1 is intended to be fixed to a table of a milling machine. One side plate surface of the vertical plate 2 is connected with the bottom plate 1 through the reinforcing ribs 3 to improve the strength.

A plurality of mounting holes 22 are provided on the base plate 1, and the mounting holes 22 are arranged in a horizontal direction. The positioning pins 21 are symmetrically arranged on the two horizontal sides of each mounting hole 22, and a nut 23 is welded and fixed between every two adjacent mounting holes 22.

The support tube 4 comprises a plug-in connection part, a bearing part and a limiting part arranged between the plug-in connection part and the bearing part. The insertion portion is for insertion into the mounting hole 22, and the support tube 4 is fixed at the mounting hole 22 by the connection bolt. The carrier part is intended to be inserted into the slide valve sleeve 9 for positioning and supporting the slide valve sleeve 9. The diameter of the limiting part is the largest and is attached to the vertical plate 2, and the two positioning pins 21 penetrate through the limiting part to conduct angular limiting. Because the end face of the slide valve sleeve 9 is provided with two positioning holes, the pin is just inserted into the positioning holes, so that the pin can simultaneously limit the supporting tube 4 and the slide valve sleeve 9 in an angle direction.

One end of the pull rod is in threaded connection with the nut 23, the rod body of the pull rod penetrates through the pressing block 6, and the other end of the pull rod is provided with the cam locking handle 8. The pressing block 6 is used for simultaneously pressing two slide valve sleeves 9 by rotating.

The specific implementation process is as follows: the slide valve sleeves 9 are sleeved on the support tube 4 one by one, and pins are inserted into process holes in the slide valve sleeves 9, so that the slide valve sleeves 9 are fully supported and positioned. The pull rod is then connected to the nut 23 and is gradually screwed until the press block 6 presses the two slide valve sleeves 9 against the riser 2, after which the cam lock handle 8 is rotated to fix the slide valve sleeves 9 thoroughly. The outer wall surface of the slide valve sleeve 9 can be milled. The reason why the slide valve sleeve 9 is not completely fixed by means of threads here is that: during tightening, the friction force acting on the press block 6 is increased to cause the press block 6 to rotate and disengage from the slide valve sleeve 9.

According to the scheme, two slide valve sleeves 9 can be clamped and fixed at one time, a plurality of slide valve sleeves 9 can be fixed at one time on the whole tool, and therefore machining of the slide valve sleeves 9 is completed at one time on a milling machine. And the production efficiency is improved.

It should be noted that the present example should not be limited to the machining of the slide valve sleeve 9, and other thick-wall pipe parts having similar machining needs can be produced by using the tooling scheme. For the condition that the end face of the pipe part is not provided with a positioning hole, the processing hole can be completely processed and then matched with a tool for application, the application of the tool scheme is free from barriers, and the processing hole can be blocked after processing.
