Overturning tool for machining workpiece with inclined cross holes

Abstract

The invention discloses an overturning tool for machining a workpiece with inclined cross holes. The overturning tool comprises a shell and a fastening screw plug, and a part mounting hole is formed in one side of the shell and used for assembling a to-be-machined part. A screw plug mounting hole is formed in the outer side of the part mounting hole, and the fastening screw plug is screwed in thescrew plug mounting hole. The fastening screw plug abuts against the to-be-machined part, and the fastening screw plug is used for clamping the to-be-machined part. A plurality of inclined cross holesto be machined need to be machined in the part to be machined. Machining receding holes penetrating outwards are formed in the positions, corresponding to the inclined cross holes to be machined, ofthe shell, and the axes of the machining receding holes and the axes of the inclined cross holes to be machined are collinear. A plurality of machining faces are arranged on the outer side of the shell, and each machining face is perpendicular to the axis of the machining receding hole in the corresponding position. Each machining face is provided with a mounting base face arranged in parallel, and the mounting base face is arranged on the other side, opposite to the machining face, of the exterior of the shell. The overturning tool solves the technical problems that in the prior art, when multiple inclined cross holes are machined, clamping is complex, and precision is not easy to guarantee; and meanwhile, cutter setting and machining difficulty is large.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a turning tool for processing workpieces with oblique cross holes. Background technique [0002] In the field of normal temperature valves, the inside of the piston is an array of drilled cross holes, and the internal space is narrow and complicated. Ordinary vertical machining centers or horizontal machining centers can only process surfaces perpendicular to the direction of the main axis, and their machining range is very limited. If the space holes are to be machined with ordinary equipment, molds need to be made, and several times of clamping is required. It is difficult to guarantee the position and accuracy of the hole during the repeated clamping process. The oblique intersecting holes of the spool are distributed at a certain angle in the circumferential direction, and have the characteristics of small hole diameter and difficult positioning. At...
