Description
Technical field
The present invention relates to the main shaft counterweight nitrogen balance system of lathe class machining center, specifically a kind of guide structure of nitrogen balance cylinder piston rod.
Background technique
The nitrogen balance system of lathe class machining center, instead of traditional main shaft balancing weight counterweight, had both decreased raw-material resource loss, reduced the gross weight of lathe, also reduces the microseismic activity that motion of main shaft produces simultaneously, improves Product Precision.
Oil cylinder in nitrogen balance system, is provided with guide sleeve between the front cover and piston rod of cylinder barrel, plays sealing and support piston bar.Existing guide sleeve poor sealing performance, thus affect the working life of oil cylinder.
Summary of the invention
The present invention is directed to the problems referred to above, provide a kind of guide structure of nitrogen balance cylinder piston rod, this guide structure good seal performance, can improve the working life of oil cylinder.
According to technological scheme of the present invention: a kind of guide structure of nitrogen balance cylinder piston rod, comprise cylinder barrel, piston rod, front cover and guide sleeve, described front cover is fixed on the front end of described cylinder barrel, described piston rod is installed in described cylinder barrel also through described front cover, between described front cover and described piston rod, described guide sleeve is installed, between described guide sleeve and described piston rod, dust cap is installed, between described front cover and described piston rod, seal ring is installed.
Described guide sleeve comprises cylindric body, the rear end outer wall of described body is provided with flange, the inwall of described body is disposed with the first coaxial endoporus and the second endoporus to the back-end from front end, the diameter of described first endoporus is greater than the diameter of described second endoporus, is provided with dust cap mounting groove between described first endoporus and described second endoporus; Described dust cap is embedded in described dust cap mounting groove, and stretches out forward from described first endoporus; The front side of described front cover has groove, and the flange of described guide sleeve is installed in described groove, and is pressed on described front cover by mounting plate.
Described seal ring is resisted against on the ear end face of described guide sleeve.
The cross section of described seal ring is U-shaped.
The material of described guide sleeve is tin bronze.
Packing ring is provided with between the front-end face of described cylinder barrel and described front cover.
Technique effect of the present invention is: the present invention is provided with dust cap in the front end of guide sleeve, and its rear end is provided with seal ring, good seal performance, can ensure that dust does not fall into cylinder barrel, extend the life-span of oil cylinder; The material of guide sleeve is tin bronze, soft, wear-resisting, has both decreased the wearing and tearing rubbing and bring, and has turn improved the protection to piston rod.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of the guide sleeve in the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
