Detailed Description

The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following description.

As shown in fig. 1 to 3, the electromagnetic valve sleeve positioning tool includes a supporting and clamping mechanism and a calibration shaft 1; the support clamping mechanism clamps the long sleeve 2, one end of the calibration shaft 1 is fittingly penetrated into a central hole of the long sleeve 2, and the other end of the calibration shaft 1 is fittingly penetrated through the end piece 3 and extends out of the end piece 3.

In the scheme, the outer diameter of the calibration shaft 1 is matched with the central holes of the long sleeve 2 and the end piece 3, and the central holes are calibrated when the calibration shaft penetrates into the central holes. The end faces of the long sleeve 2 and the end piece 3 are close to each other by moving the calibration shaft 1 along the axial direction, the calibration shaft 1 is rotated, the position with the smallest end face gap is selected, and then welding is carried out, so that good precision is guaranteed.

In the calibration, when the long sleeve 2 and the end head piece 3 are not matched, the other end head piece 3 can be selected to be matched and then welded.

In order to ensure good adaptive calibration, a first rolling unit and a second rolling unit are arranged on the cylindrical surface of the calibration shaft 1, the first rolling unit is in adaptive contact with the central hole of the long sleeve member 2, and the second rolling unit is in adaptive contact with the central hole of the end piece 3.

As shown in fig. 2 and 3, the first rolling unit includes a plurality of cylindrical rollers 4 mounted via a rotating shaft, which is parallel to the axis of the calibration shaft 1. The second rolling unit includes a plurality of ball rollers 5 installed through a cover plate 501, and the ball rollers 5 are telescopically arranged through springs 502.

Preferably, one end of the calibration shaft 1 is positioned in the long sleeve 2, the other end of the calibration shaft extends out after passing through the end head piece 3, the extending end is provided with a through hole along the radial direction, and a handle 6 which can be taken out is arranged in the through hole; the calibration shaft 1 is rotated and moved by the handle 6.

In this embodiment, the supporting mechanism includes a base 701, a supporting column 702, and two semicircular clamps 703, wherein the lower end of the supporting column 702 is fixed on the base, and the upper end of the supporting column 702 clamps the long sleeve 2 through the two semicircular clamps 703.
