Abstract

The invention discloses a pitch positioning tool for a multi-hole workpiece. According to the pitch positioning tool, the positioning is convenient and the multi-hole workpiece is difficult to move in the machining process. The pitch positioning tool comprises a base, wherein a central hole is formed in the base; a positioning column which is matched with a positioning hole serving as a datum point of the hole to be machined of the multi-hole workpiece is arranged on the base; the center distance from the positioning column to the central hole of the base is equal to the center distance from the positioning hole to the hole to be machined; and a pressing device and a positioning device matched with the multi-hole workpiece are arranged on the base. Due to the pitch positioning structure, the hole to be machined of the multi-hole workpiece can be conveniently aligned to the central hole on the base, and the multi-hole workpiece and the positioning column are fixed on the base through a locking device and a positioning device after alignment, so that the multi-hole workpiece can be effectively prevented from moving in the machining process; and therefore, the machining precision of the multi-hole workpiece is reliably guaranteed.

Description

technical field [0001] The invention relates to a positioning tool on a machine tool, in particular to a hole distance positioning tool for workpieces with holes. Background technique [0002] At present, for some porous workpieces with more than two holes, when the holes to be processed are bored, since the holes to be processed are usually not in the center of the porous workpiece, they are clamped on the clamping mechanism of the machine tool by a tool. The specific structure of the tooling includes: a bottom plate, one side of the bottom plate is provided with a clamping head matching with the clamping mechanism of the machine tool, and the other side of the bottom plate is provided with a pressing plate and a positioning plate matching with the porous workpiece. When clamping, first, align the center line of the hole to be processed in the porous workpiece with the machining axis, then fix the work on the base plate through the pressure plate and positioning plate, and ...
