Wheel-shaped workpiece radial loading durability test device and test method

Abstract

The invention discloses a wheel-shaped workpiece radial loading durability test device and test method, and relates to the field of production detection of a magnetic product. The device comprises a roller driven to rotate and a bearing component driven to be linearly and radially close to the roller; clamping grooves are formed at the upper side of one end of the bearing component, which faces the roller; the bearing component is a rectangular frame body of which one side is open; the clamping grooves are symmetrically formed on the frame body at both sides of an opening of the rectangular frame body; and groove bottoms of the clamping grooves are inclined relative to rabbets towards the direction away from the roller. A to-be-tested workpiece is fixed at the middle part of a rotating shaft, the rotating shaft is clamped in the clamping grooves, the bearing component is driven to be close to the roller so as to enable the to-be-tested workpiece to be in contact with the roller, and the roller drives the to-be-tested workpiece to rotate and applies a radial load. According to the invention, overload operation of the workpiece in an actual working state can be simulated and then defects hidden inside the workpiece can be sufficiently exposed in the short-time testing process so as to find and overcome the product defects, thereby improving product quality and prolonging the service life of the product.

Description

technical field [0001] The invention relates to the technical field of production and detection of magnetic products, in particular to a radial load durability test device and a test method for a wheel-shaped workpiece. Background technique [0002] Ferrite is a new type of non-metallic magnetic material that has developed rapidly since the 1940s. In the production process, the ferrite forming process is similar to the general ceramic process, which is easy to operate and easy to control, unlike metal magnetic materials that require complicated processing such as rolling. Compared with metal magnetic materials, ferrite has the advantages of large resistivity, high dielectric properties, and high magnetic permeability at high frequencies. Because ferrite magnetic products have good performance, low cost, simple process, and can save a lot of precious metals, they are widely used in electronic industry sectors such as communication broadcasting, automatic control, computing t...
