Problems solved by technology

At present, when quenching and strengthening the V-shaped roller cross linear guide, a simple gate structure is used, so it is impossible to form a uniform hardened layer on the V-shaped raceway surface
At the same time, since the installation hole of the guide rail is an eccentric structural layout that is biased towards the bottom side, the use of a surface quenching sensor with a symmetrical gap size will easily result in high hardness of the bottom surface and a deep hardened layer, making it impossible to process the installation hole

Embodiment Construction

[0017] A V-type roller cross linear guide surface induction hardening sensor, see image 3 , the inductor includes an inductive conductor 1, a magnetizer 2 and a fixing piece 3. The inductive conductor 1 made of a hollow copper tube is a door-shaped structure that is adapted to the section of the V-shaped roller cross linear guide 5, wherein, in The position corresponding to the V-shaped raceway surface 14 of the V-shaped roller cross linear guide is also V-shaped. The gap between the side edge of the inductive conductor 1 of the gate structure and the bottom surface 11 close to the bottom surface 11 of the V-shaped roller cross linear guide rail is 4.5-5.0mm. The magnetizer 2 adapted to the V-shaped raceway surface 14 of the V-shaped roller cross linear guide is arranged on the inductive conductor 1 and is located at the V-shaped place; the magnetizer 2 is also the V-shaped roller cross linear guide. The V-shaped raceway surface 14 is matched with a V-shaped structure, and t...

Abstract

The invention discloses a surface induction hardening inductor for a V-shaped roller cross linear guide rail, which comprises an inducing conductor, a magnetizer and a fixing piece, wherein the inducing conductor made of a hollow copper tube adopts a door-type structure adapting to the cross section of the V-shaped roller cross linear guide rail; the magnetizer adapting to a V-shaped raceway surface of the V-shaped roller cross linear guide rail is arranged on the inducing conductor; and the fixing piece is arranged on the inducing conductor. The surface induction hardening inductor can achieve surface induction heating on the raceway surface and the bottom surface of the guide rail at the same time under different temperatures, different surface hardness and different hardening layer depths, ensures that a hardening layer with high hardness and high strength is formed on the raceway surface and the hardening layer has the bottom surface with certain hardness at the same time, and satisfies the requirements of quenching deformation of the guiding rail and the mounting hole processing.

Description

technical field [0001] The invention relates to a surface induction hardening inductor, in particular to a surface induction hardening inductor for a V-shaped roller cross linear guideway. technical background [0002] The V-shaped roller crossed linear guideway pair is composed of two guide rails with V-shaped raceways, roller cages, cylindrical rollers, etc. The cross-arranged cylindrical rollers are formed on the precision-ground V-shaped raceway surface. Reciprocating motion, can withstand loads in all directions, and achieve high-precision, smooth linear motion. figure 1 It is a schematic diagram of the working state of the V-type roller cross linear guide pair. Due to the asymmetric shape of the V-shaped roller cross linear guide, quenching and strengthening the V-shaped raceway surface alone will cause an asymmetric distribution of the hardened layer and residual stress of the guide rail, resulting in quenching deformation and difficult alignment. [0003] When the ...
