Abstract

The invention discloses a multi-working-procedure combined machining device for a horizontal axis, which relates to the technical field of machine tool parts and comprises a positioning block, a pressing mechanism, a positioning plate and a cutter, wherein the positioning block is provided with a positioning tool, the positioning block is operably arranged on a chuck, the pressing mechanism and the positioning block are oppositely arranged, the pressing mechanism and the positioning block are operably used for clamping the radial direction of the horizontal axis, the pressing mechanism and the chuck synchronously rotate, the positioning plate is symmetrically and fixedly arranged on the side surface of the positioning block, and the positioning plate is operably used for clamping the axial direction of the horizontal axis. The positioning plate is symmetrically fixed on the side surface of the positioning block, so that axial movement is effectively limited, clamping stability is improved, and by rotating the positioning block by a certain angle, the middle part of the positioning block is only required to be replaced by a cutter, and the different positions on the linear shaft can be processed without repositioning the linear shaft, so that repeated positioning errors caused by repeated clamping in the traditional processing are avoided, and processing precision and efficiency are remarkably improved.
