Abstract
The utility model relates to an endless belt protector for a length sensor of a machine tool, which is provided with all components of a conventional sensor except for a soft rubber belt. In addition, the longitudinal circle of a casing of a seal cavity is wrapped by a belt of which both ends are fixed to a connecting rod rest of a moving part, and then, moveable seal which forms an endless belt shape is formed and follows the moving part to move; during the movement of the moving part, the moveable seal can still have favorable seal performance, and thus, dirt is prevented from entering the seal cavity to pollute a grating, a magnetic grid, etc. of the sensor. The sensor provided with the utility model does not need cleaning or maintaining for a long time, and the sensor can still maintain high precision.
Description
The utility model relates to the grating that is used for the machining lathe, the endless belt formula sealing dust-proof device of magnetic railings ruler equal length detecting sensor, particularly sensor.
The linear transducer that uses on the existing lathe, the enclosed cavity that all has a shell and flexible glue band to form, quiet is fixed in this chamber, moving part stretches into enclosed cavity and by the flexible glue band on both sides it is clamped and form soft seal, moving part moves and exports the signal of displacement relative to quiet, the connecting rod of moving part is to move in the crack of both sides flexible glue band simultaneously, still has greasy dirt, dust, the cooling fluid of trace to enter enclosed cavity in its moving process, is bonded on dynamic and static.It generally all is contaminated between dynamic and static that existing various sensors break down, and makes grating sensor phase drift occur, pulse-losing; Make the magnetic induction sensor attenuated signal, and testing result is made mistakes, thereby sensor needs often dismounting solvent clean.
The purpose of this utility model is to provide a kind of endless belt formula protector, and the moving part that makes sensor is in moving process, and its enclosed cavity still is in reliable sealing state, and dirt can not enter in the enclosed cavity, to reduce the maintenance work amount effectively.
Described endless belt formula protector, have conventional sensors except that both sides sealings with the entire infrastructure the flexible glue band, other have ribbon one end to be fixed on the connecting rod rest of moving part and vertically around one week of enclosed cavity housing the back other end also be fixed on the connecting rod rest.Form the ring-band shape movable sealing.When the moving part straight line moves, can drive endless belt and move.
Roller bearing can be adorned in enclosed cavity housing two ends, reduces the frictional force that endless belt moves.
The material of endless belt can use stainless steel strip, teflin tape or other rubber-like oil resistant plastic band.
But endless belt follower of the present utility model moves the formation dynamic seal (packing) isolates the enclosed cavity and the external world fully.Adopt the sensor of described device and the result of conventional sensors contrast use to show that conventional sensors needs about three months cleaning maintenances can keep precision, and adopts the sensor of described device to use more than 2 years, still keeps satisfied precision.It is simple in structure, practical, greatly reduces the workload of maintenance.
Fig. 1, the longitudinal sectional view of described device.
Fig. 2, the transverse sectional view of described device.
Embodiment one, referring to Fig. 1;
Polytetrafluoroethylene (PTFE) strip 1 one ends are fixed on the moving part support 5, and vertically the housing 6 one all backs other ends around enclosed cavity also are fixed on formation sealing on the support 5.Frictional force when housing 6 two ends are equipped with roller bearing 4 and are reduced endless belt and move.Moving part 2 endless belt 1 when moving for quiet 3 moves with it.
Embodiment two, referring to Fig. 2.
Claims (4)
1, the endless belt formula protector of lathe linear transducer, it has conventional sensors to remove the entire infrastructure of both sides sealing with the flexible glue band, it is characterized in that, there is an end of ribbon 1 to be fixed on the connecting rod rest 5 of moving part, and vertically also be fixed on the connecting rod rest 5 around enclosed cavity housing 6 one all backs other ends, form the movable sealing of endless belt 1 shape.
2,, it is characterized in that housing 6 two ends are equipped with roller bearing 4 by the described device of claim 1.
3, by the described device of claim 1, the material that it is characterized in that endless belt 1 is thin stainless steel band.
