Linear guide determines the quality of linear motor

The linear guide rail will also play a decisive role in the performance and quality of the linear motor. Linear motors are increasingly used in industrial applications to replace mechanical drives with easy wear. They can provide high speed and acceleration, good adjustment accuracy and precise positioning. The advantages of linear motor is that the supply of electrical energy can be directly converted into linear motion, completely any intermediate element for applications in the field of linear motor torque conversion machinery is widely not required, including medical technology, optics, electronics, textile industry, machinery manufacturing, handling conveying and packaging industry etc.. For example, the manufacturing process of electronic structural components and processing requirements are very high: the size of 1mm x 0.5mm electronic components must be very high accuracy and the positioning of the plug-in security. The automatic device is inserted in the electronic industry, the operation cycle time is often less than 0.5s, the positioning accuracy of driving device must reach 5 m and reached a high value of the acceleration of mechanical requirements are particularly high the use of linear motor can achieve the acceleration of linear guide mechanical structure and a very high demand structure is proposed. In the operation of linear motor will produce a very high axial force. The guide must absorb the force of the 3000N. Therefore, it is necessary to have a light weight, high rigidity and strong mechanical guide device in high dynamic operation. Machine level calibration. With two high gauge and a marble scale on the installation base on the linear guide, on the level of precision instrument debugging base level requirement is the base of convex (2~3 lattice) linear guide rail mounting surface roughness, flatness, straightness and appearance inspection. Requirements: when the level of measurement must be debugged after the main linear guide rail mounting surface by laser interference (we usually in a straight line guide rail surface near the right column) flatness allows each 10m convex 0.05mm, full stroke straightness allowed convex 0.03mm. Roughness requirements 1.6, appearance without casting defects. Chamfer treatment of linear guide rail mounting base surface and guide rail side reference mounting surface. Requirements: the fillet radius is less than or equal to 3.5mm, if found too large chamfer or protruding, should promptly use oilstone and file processing, otherwise it will cause the precision of the track installation or bad will interfere with the slider. Processing of locking thread hole of linear guide rail mounting base. Required to confirm the location of the installation screw is correct, the central distance of each connected screw 120mm greater than 0.1mm or less than 0.1mm; in order to ensure high-precision screw processing, the need to use numerical control equipment positioning processing. Inspection of linear guide rail after unpacking. Requirements: check whether there is a straight line guide certificate, there is no damage or rust, rust cleaning oil, clean the surface of the assembly of the burr, bump and dirt, etc..
