High-precision pentahedral machining machine tool

Abstract

The invention relates to a high-precision pentahedral machining machine tool which comprises a machine tool body, a workbench, a beam, a left upright post, a right upright post, an electrical control body, a control board, a main transmission case, a slide pillow, a dragging plate, a cutter storeroom, an automatic head storeroom, a right-angle cutter head and a chip discharger. Guide rails respectively comprise linear rolling guide rails arranged at the left side and the right side of the machine tool body and an inserted steel rolling guide rail arranged in the middle of the machine tool body, wherein the inserted steel rolling guide rail comprises an inserted steel piece, a rolling piece and a fixing piece of the rolling piece. The center of a spindle of the right-angle cutter head is provided with a pull rod sleeved with a butterfly-shaped spring, and the right end of the pull rod is connected with a clamping claw. The inserted rolling guide rail also comprises an oil cylinder knife loosening device, and embedded parts of heat storeroom shells are embedded in the right upright post. The invention has the advantages of high processing precision, easy assembly, good interchangeability of machine tool parts, occupied space reduction of the machine tool and head replacement speed improvement.

Description

technical field [0001] The invention relates to an improvement of a pentahedron processing machine tool, in particular to a high-precision pentahedron processing machine tool. Background technique [0002] The guide rails of the existing high-precision pentahedron processing machine tools are double linear rolling guide rails or three linear rolling guide rail structures; when the double linear rolling guide rail structure has a large load, the table top is easily deformed; for the installation of the three linear rolling guide rail structure, the machine tool The body and the worktable must be in the same plane, which puts forward higher requirements on the machining accuracy of the machine bed and workbench, and the processing cost will also increase. [0003] The right-angle milling head of the existing pentahedron machining center machine tool needs the ram to move to a specific position when changing the tool, which can be realized by the auxiliary tool release mechanis...
