The valve sleeve part is characterized by a plurality of holes, wherein the valve sleeve part also comprises a plurality of spark square holes, and the square holes are required to ensure the dimensional requirement of the axial position and the coplanarity requirement. At present, the valve sleeve electric spark square hole is processed through a non-automatic line, the valve sleeve is positioned and clamped mainly through a V-shaped block, the electric spark square hole in one direction is processed, the valve sleeve needs to be turned over manually and needs to be repositioned, the efficiency is low, errors are easy to generate, and the valve sleeve electric spark square hole processing method cannot adapt to the installation and positioning requirements of an electric spark automatic line. In order to meet the requirements of the electric spark automation line, the valve sleeve must be pre-installed and aligned before entering the electric spark automation line, and after installation, the valve sleeve can flow along with the 3R positioning chuck without changing the alignment state of the valve sleeve.
Due to the deviation of the dimensional accuracy of the valve sleeve, when the valve sleeve is arranged on the valve sleeve mounting seat in a clearance fit manner, the axis of the valve sleeve is not strictly vertical relative to the plane of the mounting seat, and the valve sleeve can be skewed at a certain angle, so that the position accuracy and the coplanarity of the valve sleeve after the electric spark square hole is machined subsequently can be influenced. The four adjusting screws on the horizontal correcting seat are adjusted to drive the valve sleeve mounting seat to generate adjustment of a horizontal angle, so that the deflection of the axis of the valve sleeve relative to the plane of the mounting seat is offset, and the aim of mounting the valve sleeve axis and the plane of the mounting seat in a mutually perpendicular mode is fulfilled.

the valve sleeve mounting seat is provided with a vertical positioning shaft, and the positioning shaft is in clearance fit with the inner hole of the valve sleeve;
the horizontal correcting seat comprises an adjusting plate, a supporting plate and four adjusting screws, the lower end of each adjusting screw is rotatably supported on the supporting plate, the supporting plate and the turntable are fixedly installed, each adjusting screw penetrates through the adjusting plate and is in threaded fit with the adjusting plate, and the adjusting plate can axially move relative to the screw by rotating the adjusting screws; the four adjusting screws are uniformly distributed relative to the axis of the positioning shaft.
Furthermore, a bearing is arranged between the lower end of each adjusting screw and the support plate.
Furthermore, the support is a three-degree-of-freedom support.
Furthermore, the outer edge of the rotating disc is a sawtooth-shaped outer edge.
Furthermore, the support comprises a cantilever and a joint bearing, and the cantilever and the joint bearing can be locked.
Further, the turntable is rotatably arranged on the horizontal plane through a bearing.
