Reference block inclined hole machining and positioning device

The utility model relates to the technical field of processing and positioning, in particular to a reference block inclined hole processing and positioning device, which is characterized in that an external member drives the left end of a positioning plate to move up and down, so as to adjust the angle of a wheel shaft for supporting the positioning plate, improve the diversity of angle adjustment of the positioning plate and reduce the limitation of device inclined angle adjustment. By arranging a first sliding rail and a top plate, the moving stability of a wheel shaft is improved, the fixing stability of a reference block by a positioning plate is improved, by arranging a rotatable wheel shaft, friction between the wheel shaft and the bottom end of the positioning plate is reduced, the service life of the device is prolonged, and the practicability of the device is improved; comprising a connecting base, a supporting column, a top plate, a stand column, a sleeve piece, a first fixing bolt, a positioning pl
