Abstract
The utility model discloses a hydrostatic guideway device. The hydrostatic guideway device comprises a sliding shaft fixed on a gang saw machine, a sliding pipe sleeving the sliding shaft, and a first fixed seat sleeving the sliding pipe and fixedly connected with the sliding pipe, wherein the first fixed seat is fixed on the sliding pipe through a nut and a sun piece. As the sliding shaft is fixed on the gang saw machine, the sliding pipe directly sleeves the sliding shaft, and the first fixed seat is directly fixed on the sliding pipe through the nut and the sun piece; thus, the gap between the sliding pipe and the sliding shaft is stable, no friction is generated, and the service life of the hydrostatic guideway device is prolonged. Meanwhile, the condition that the first fixed seat is acutely impacted and vibrated to break away from the sliding pipe during reciprocating motion to further influence the gap between the sliding pipe and the sliding shaft to cause friction damage is avoided.

The specific embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail.It should be noted that, the utility model accompanying drawing all adopts the form of simplification and all uses non-ratio accurately, only in order to convenient, the object of aid illustration the utility model embodiment lucidly.
The utility model provides a kind of static-pressure guide device, as shown in Fig. 1～4, comprising: be fixed on sliding axle 100 on gang saw mill, be set in the sliding tube 200 on described sliding axle 100 and be set in the first holder 300 on described sliding tube 200.As preferably, described sliding tube 200 is cylinder, and described the first holder 300 is fixed on described sliding tube 200 by nut 600 and sun sheet 700.Particularly, the two ends of described sliding tube 200 are provided with screw thread, the first holder 300 is between screw thread, described nut 600 is fixed on sliding tube 200 by this screw thread, thereby fix the first holder 300, avoid the first holder 300 in reciprocating motion process to be subject to severe impact vibration and to depart from sliding tube 200, and then affect the gap between sliding tube 200 and sliding axle 100, cause frictionally damage.Described sun sheet 700 is fixed between nut 600 and the first holder 300, plays buffer action, avoids producing and rubbing, cause damage between nut 600 and the first holder 300.
Further, the two ends of described sliding axle 100 are provided with fixture 400, and described sliding axle 100 is connected with gang saw mill by fixture 400.Continue referring to Fig. 1～4, described fixture 400 is the circular securing members of two halves, and described two securing members are fixedly connected with gang saw mill with described sliding axle 100 by bolt.
