The linear guide used together with other factors plays a decisive role in the performance and quality of the linear motor. Therefore, the linear guide determines the quality of the linear motor.
Linear motors are increasingly replacing drive devices with wear-resistant mechanical transmission components in industrial applications. They can provide high speed and acceleration, fine adjustment accuracy and precise positioning. The advantage of a linear motor is that the supplied electrical energy can be directly converted into linear motion. There is no need for any intermediate components for torque conversion machinery. Linear motors are used in a wide range of applications, including medical technology, optics, electronics, textile industry, machinery. Manufacturing, handling, transportation and packaging industries, etc.
For example, the process of manufacturing and processing electronic structural components is very demanding: electronic components having a size of 1 mm x 0.5 mm must be positioned with very high precision and security of the insertion. In the electronics industry, the operating cycle time of the automatic device is often less than 0.5 s, the drive device must reach a positioning accuracy of 5 μm and achieve a high acceleration value. The mechanical requirements are particularly high. The acceleration that can be achieved with a linear motor is linear. The mechanical structure puts high demands on it.
Linear motors produce high permanent axial forces during operation and the guide must absorb the 3000 N forces that occur. As a result, lightweight, rigid, and robust mechanical guides are required in highly dynamic operational applications.
Machine level correction. The linear guide rail requires two equal height blocks and a marble ruler to be placed on the mounting base surface, and a precise level meter is used to adjust the base level. The requirement is that the base convex (2 to 3 grid) linear guide rails be installed with the base surface roughness. Flatness, straightness and appearance inspection. Requirement: After horizontal debugging, the plane of the main linear guide mounting base must be measured with a laser interferometer (usually a straight guide rail surface that is close to the right side guide is the main guide rail). The flatness of the main guide rail is allowed to be 0.05mm per 10m. Stroke straightness allows convex 0.03mm. Roughness requirements 1.6, appearance no casting defects. Signage production
Chamfering of the linear guide mounting base surface and the rail side reference mounting surface. Requirements: The radius of chamfer is less than or equal to 3.5mm. If the chamfer is found to be too large or convex, it should be treated with oilstone and boring tool in time. Otherwise, it will cause poor installation of the guide rail or interfere with the slider.
Linear guide mounting base surface locking screw hole processing. Requirements: Make sure the position of the mounting screw hole is correct. The center distance between each screw hole is 120mm larger than 0.1mm or less than 0.1mm. In order to ensure high-precision screw hole processing, CNC equipment is required to position and process.
Check the linear guides after opening the box. Requirements: Check whether the linear guide has a certificate, whether it has bumps or rust, clean the rust-proof oil, remove the burrs on the assembly surface, impact protrusions and dirt and so on.
