Abstract
The utility model relates to a self-cleaning device for a length detection sensor of a machine tool. Oilproof and soft objects, such as felt, foamed plastics, etc. are respectively adhered to a moving part of a conventional sensor, which corresponds to both sides of the working face of a static part. During a working process, the utility model can clean dirt on the static part, keep the moving part and the static part to be clean and enable the sensor which is not dismounted to be washed after long-time use to keep favorable precision. The utility model has the advantage of simple and practical structure, and greatly reduces the work load of maintaining the sensor.
Description
The utility model relates to the cleaning apparatus for self of the sensor, particularly sensor of the grating that is used for the machining lathe, magnetic railings ruler equal length checkout gear.
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, and moving part stretches into enclosed cavity and by the flexible glue band on both sides its clamping is formed soft seal.Moving part moves and exports the signal of displacement relative to quiet, and the connecting rod of moving part is to move in the crack of two flexible glue bands simultaneously, still has greasy dirt, dust, the cooling fluid of trace to enter enclosed cavity in its moving process.It generally all is contaminated between dynamic and static that existing various sensors are out of order, and makes grating sensor phase drift, pulse-losing occur, makes 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 sensor cleaning apparatus for self that in use cleans pollutant on the working sensor face automatically, to reduce its maintenance work amount.
Described sensor has the entire infrastructure of conventional sensors from clear device, and on moving part quiet relatively the both sides bonding oil resistant soft-body respectively of working face.And the another side of oil resistant soft-body is close to quiet, can move relative to it.
The felt that above-mentioned oil resistant soft-body is soft or the oil resistant plastic cement thing of foaming.
The utility model in the course of the work, the mobile drive oil resistant soft-body of moving part moves relative to quiet, can clean quiet the dirt on the working face, makes between dynamic and static and remains cleaning.Adopt the sensor of described device and the result of conventional sensors contrast use to show that conventional sensors generally needs about three months cleaning maintenances can keep precision, and adopts the sensor use of described device still to keep satisfied precision more than 1 year.It is simple and practical, greatly reduces the maintenance work amount.
Fig. 1, band is from the sensor schematic cross section of clear device.
Fig. 2 is the A-A cutaway view of Fig. 1.
Embodiment one,
Shell 5 is fixed on the Working gantry of lathe, be fixed in for quiet 4 in the shell 5, moving part 2 is fixed on movably on the workbench and stretches in the shell 5, flexible glue band 1 clamps moving part 2, form soft seal, difference bonding oil resistant soft-body 3 in the both sides of the working face of quiet relatively body 4 on the moving part 2, it is soft felt.
Embodiment two,
Oil resistant soft-body 3 is plastic cement of foaming, and all the other are identical with embodiment one.
Claims (2)
1, lathe length is controlled the cleaning apparatus for self of sensor, and the entire infrastructure of conventional sensors is arranged, it is characterized in that, and difference bonding oil resistant soft-body 3 in the both sides of quiet relatively 4 working face on the moving part 2, the opposite side of soft-body 3 is close to quiet 4, can relatively move.
2, described by claim 1 from clear device, it is characterized in that oil resistant soft-body 3 is the soft felt or the oil resistant plastic cement thing of foaming.
