The gib block that thick stick is arranged in parallel；One is arranged in the arc plate slide outside adopt saddle axle made by polyvinylidene fluoride material
Set, the inner side of the saddle axle sleeve has the type face being engaged with arc plate outside；With the arc plate top notch
The saddle of an arc-shaped is fastenedly connected on the inside of the relative saddle axle sleeve, is provided with the saddle and is matched with the screw mandrel
The screw thread of conjunction.
The inside and outside circle of the ceramic bearing and the material of rolling element are adopted by zirconium oxide, silicon nitride and carborundum structure
Into composite；Material used by the retainer of the ceramic bearing is politef, nylon66 fiber, polyetherimide ammonia, oxidation
One of zirconium, silicon nitride, rustless steel and extraordinary aviation aluminum.
There is polyphenylene oxide composite material in the Surface coating of the ceramic bearing.
In the base periphery one can be nested with using bracing frame made by polyvinylidene fluoride material.
The polyvinylidene fluoride material is adopted and formed by the vinylidene homopolymerization of purity >=99.99%.
Due to taking above technical scheme, it has advantages below to the present invention：1st, directive slide track of the invention is due to justifying
The outer wall of arc plate is provided with a plurality of gib block being arranged in parallel with leading screw, therefore the directive slide track of the structure can not only provide super
Cross the torsional rigidity and stability of its size and weight, but also higher linear velocity can be provided and stablizing for accurate positioning is led
To.2nd, the present invention is due to using the base design integrated with directive slide track, therefore the base of integration is in the whole work of needs
Make the supporting that effect can be provided with length range.3rd, the present invention using ceramic bearing support screw due to being rotated, and is being made pottery
Porcelain bearing surface is coated with one layer of PPE (polyphenylene oxide) composite, therefore the present invention operationally has more preferable resistance to high speed, resistance to
High temperature and the characteristic such as corrosion-resistant.4th, it is of the invention because the rustless steel for having corrosion-resistant PTFE (politef) using surface spraying is led
To slide rail, therefore directive slide track operationally has antiacid, alkali resistant, high temperature resistant and reduces the characteristic of coefficient of friction.5th, the present invention
Saddle axle sleeve and bracing frame due to being made using PVDF (Kynoar), therefore with preferable super-weathering resistance energy, corrosion resistant
Corrosion and processing characteristics, and can operationally realize that wear-compensating and gapless drive.6th, the permission work of apparatus of the present invention
Speed more than 60 inch per seconds (1.5 meter per second), and can have the advantages that corrosion-resistant, long working life and low cost of manufacture.
