Description

Linear motor module adopting embedded ceramic guide rail

Technical Field

The utility model belongs to the technical field of the linear motion module, in particular to adopt embedded ceramic guide rail's linear electric motor module.

Background

The linear motor is a direct drive motor. By unfolding the closed magnetic field into an open magnetic field, electrical energy is directly converted into mechanical energy for linear motion without any intermediate conversion mechanism transmission. The linear motor may be considered as a structure formed by cutting a rotary motor in the radial direction and spreading the circumference of the motor in a straight line.

Direct drive motors are a motion control that directly transmits thrust/torque from a power source to a load. With this arrangement, all mechanical drive components (ball screw assemblies, rack and pinion, drive belts/pulleys, and gearboxes, etc.) can be replaced, and the backlash, compliance, and other problems associated with mechanical drives are eliminated.

The linear guide is a supporting and guiding mechanism for supporting and guiding a moving member to reciprocate linearly in a given direction. Depending on the nature of the massage device, the linear guides can be divided into sliding friction guides, rolling friction guides, elastic friction guides, fluid friction guides, etc.

The traditional guide rail is made of steel materials mostly, and along with the fact that the performance requirements of oil manufacturing equipment on a linear motor module are higher and higher, the steel guide rail cannot meet the use requirements of high-end manufacturing equipment due to the material performance and the machining process of the steel guide rail. The method specifically comprises the following steps:

1. the material performance is as follows: the metal (steel) material has the aging problem, and the metal (steel) material has the advantages of large thermal expansion coefficient, low elastic modulus, low hardness (HRC 52-58), poor wear resistance and incapability of ensuring the form and position accuracy of the size of the guide rail for a long time. In addition, metallic materials are environmentally sensitive and are susceptible to rusting and corrosion.

2. The working environment influences: because the motor can generate strong magnetism after being electrified. Because the guide rail is made of steel materials, the guide rail can be magnetized when working in a strong magnetic environment for a long time, and the shape and position accuracy and the like are increasingly poor. In addition, after long-term wearing and tearing, metal dust can adsorb on the motor magnetic track, leads to module precision to descend and even damages the motor.

3. The economic efficiency is as follows:

because the hardness of the metal raw material is low before processing, the hardness of the material needs to be increased by heat treatment, and then the metal raw material can be put into use only by accuracy correction. The production cycle is long and the difficulty is high. Is not conducive to rapid mass production of modules.

In the patent application with application number CN201920184187.3, a disclosed linear guide structure relates to the guide rail field, including the steel guide rail seat, the steel guide rail seat is U type structure, the inboard bilateral symmetry of steel guide rail seat is equipped with the recess, is equipped with the steel guide rail in the recess, the steel guide rail is the rectangle structure, the steel guide rail is equipped with the direction slot towards the side of steel guide rail seat, other sides of steel guide rail all hug closely with the recess inner wall, guide rail seat and steel guide rail structure as an organic whole.

The linear guide rail structure disclosed above adopts a steel guide rail, and has drawbacks in three aspects of material performance, influence of working environment, and processing cost.
