The utility model content
The purpose of the utility model is to provide a kind of shield machine with wearing and tearing Presentation Function use the twolip hobboing cutter, to solve present shield machine with the do not wear and tear problem of Presentation Function of twolip hobboing cutter, having the accurate and advantage of simple structure of wearing and tearing demonstration.
The purpose of the utility model is to realize through following technical scheme:
A kind of shield machine with wearing and tearing Presentation Function is used the twolip hobboing cutter; Comprise that cutter hub, cutter hub axis hole that double cutting edge is installed are interior through the rotating shaft of bearing installation and the end cap of bearing outer setting; Said cutter hub is provided with an inner chamber that is communicated to each blade from roller end; Said inner chamber connects fuel transfer system, and said fuel transfer system is provided with pressure meter or pressure sensor.
Said inner chamber comprises that one is arranged on the rotating shaft center and along the horizontal main line of axis direction, said horizontal main line is provided with two oil transportation branch roads that are communicated to blade.
Said oil transportation branch road comprises the annular oil groove in cutter hub and the rotating shaft; Said annular oil groove all is opened in the position corresponding with blade on the external surface of rotating shaft and cutter hub; And be communicated with through middle chamber each other; Be communicated with through a cavity between annular oil groove in the said rotating shaft and the said horizontal main line, said blade inside has plural oil transportation hole, and is communicated with annular oil groove on the cutter hub.
Annular solid of the outside socket of said rotating shaft; And can relatively rotate each other; Said annular solid is arranged on the centre position of hobboing cutter, and the place, mating face of said annular solid and rotating shaft is provided with dynamic seal, and said annular solid and cutter hub joint are provided with the O RunddichtringO; Said blade and cutter hub junction also are provided with the O RunddichtringO, lock through key between said annular solid and the cutter hub.
The beneficial effect of the utility model is: through the inner chamber that cutter hub is provided with, inner chamber connects fuel transfer system, with the oil injection of certain pressure; Arrive each blade place of cutter hub through inner chamber; When wearing and tearing appearred in blade, the leakage of oil situation will appear in hobboing cutter, and said fuel transfer system is provided with pressure meter or pressure sensor; When wearing and tearing appearred in blade, operating personnel can find out intuitively that the pressure of inner chamber changes.In conjunction with above method, can find out the twolip hobboing cutter that has worn and torn accurately, have wearing and tearing and show accurately and advantage of simple structure.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
