Problems solved by technology

Usually, the positioning of the mandrel requires processing bolt holes and other forms on the mandrel. At the same time, multiple inspections and assemblies are required to make the assembled mandrel meet the positioning accuracy requirements, and the assembly efficiency is low. At present, there is no device that can be used without changing the mandrel. At the same time, the high-precision and high-efficiency positioning of the mandrel parts is completed, so a high-precision and high-efficiency positioning device suitable for the mandrel is needed

Abstract

The invention discloses a mandrel positioning device which comprises a bottom plate. A mandrel is placed on the bottom plate and is connected to bottom plate through a pair of symmetrically arranged pressing plates and screws, a positioning tool covers the outer part of the mandrel, the lower end of the positioning tool is buckled to the bottom plate and the upper end of the positioning tool penetrates a center hole in the top surface of the positioning tool. On the premise of not changing the structure of the mandrel, the mandrel is positioned quickly and precisely by assembly at one time, sothat the mandrel positioning difficulty is reduced, a lot of manpower resources is saved, and the mandrel positioning device is suitable for positioning the mandrel, a mandrel boss of which changes in a certain dimensional range.

Description

technical field [0001] The invention belongs to the field of positioning devices, and in particular relates to a mandrel positioning device. Background technique [0002] The mandrel is a rotary part with high dimensional accuracy. It is mainly used for assembly with other parts and plays a role in positioning other parts. It is widely used in precision test devices. Ensuring the positioning and installation accuracy of the mandrel is a prerequisite for ensuring the assembly accuracy of the entire test device. Usually, the positioning of the mandrel requires processing bolt holes and other forms on the mandrel. At the same time, multiple inspections and assemblies are required to make the assembled mandrel meet the positioning accuracy requirements, and the assembly efficiency is low. At present, there is no device that can be used without changing the mandrel. At the same time, the high-precision and high-efficiency positioning of the mandrel parts is completed, so a high-...
