Description
Technical field
The present invention relates to a kind of processing method of pin-and-hole, particularly, relate to a kind of rudder stock is connected the circular cone pin-and-hole with tiller processing method.
Background technology
Rudder stock, tiller are chief components in the shipping rudder system, and the type of attachment of tiller and rudder stock has two kinds: a kind of is the cylinder syndeton, and another kind is the cone syndeton, and wherein circular cone is connected in the present shipbuilding and is generally adopted.And strict regulation requirement is arranged for the linearity, the fineness that guarantee the circular cone pin-and-hole that rudder stock is connected with tiller, generally be difficult to reach.
Summary of the invention
The purpose of this invention is to provide a kind of being used to processes rudder stock is connected the circular cone pin-and-hole with tiller method, guarantees linearity and fineness after its processing.
In order to achieve the above object, the invention provides a kind of rudder stock is connected the circular cone pin-and-hole with tiller processing method, wherein, this method be to each circular cone pin-and-hole all adopt drilling successively, expand cut, the operation of ream carries out substep and processes, it comprises: the microcephaly's size according to the circular cone pin-and-hole drills with corresponding drill bit earlier, with one group of reamer from small to large the hole is enlarged, reamer plays the straight effect of guiding reaming neck again, forms the thick bottoming reamer hinge of shape to each hole with one at last; Hinge is during to each hole, and the ream amount of feeding is 0.3～0.5mm/r, and ream speed is 6～12m/min, and the hinge pin consumption is 0.1mm.
Above-mentioned rudder stock is connected the processing method of circular cone pin-and-hole with tiller, wherein, also adopt the good smear metal liquid of cooling performance in the described method
Above-mentioned rudder stock is connected the processing method of circular cone pin-and-hole with tiller, wherein, described cutting fluid is the smear metal liquid that wear-resistant conditioner and No. 0 diesel oil are formed with the proportioning of 1:10.Nozzle alignment is processed the aperture, and with the smear metal liquid of enough pressure, flow is in time discharged smear metal, prevents from adhering to built-up edge on the reamer cutting edge, and is influential to the fineness in hole.
Above-mentioned rudder stock is connected the processing method of circular cone pin-and-hole with tiller, wherein, described ream, the reamer of employing are 6 spiral flute profiles.Strengthened chip space like this, made chip removal smooth.Because the fraising chip removal is bad, the very big influence that bring for the fineness in hole needs to reduce the reamer number of teeth for this reason.
Above-mentioned rudder stock is connected the processing method of circular cone pin-and-hole with tiller, wherein, the relief angle of described reamer cutting tip can not be excessive, and this angular range is 8 ° ~ 9 °.
Above-mentioned rudder stock is connected the processing method of circular cone pin-and-hole with tiller, wherein, the land of described reamer can not be wide, and this width is 0.1 ~ 0.15mm.
Rudder stock provided by the invention is connected the circular cone pin-and-hole with tiller processing method has the following advantages:
Solve the processing problems of circular cone pin-and-hole, pin-and-hole and fineness are obviously promoted, satisfied processing request, improved production capacity.
Description of drawings
Fig. 1 is rudder stock of the present invention is connected the circular cone pin-and-hole with tiller the employed process equipment schematic diagram of processing method.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is further described.
Rudder stock provided by the invention is connected the processing method of circular cone pin-and-hole with tiller, be to each circular cone pin-and-hole all adopt drilling successively, expand cut, the operation of ream carries out substep and processes, it comprises: the microcephaly's size according to the circular cone pin-and-hole drills with corresponding drill bit earlier, with one group of reamer from small to large the hole is enlarged again, reamer plays the straight effect of guiding reaming neck, forms the thick bottoming reamer hinge of shape to each hole with one at last; Hinge is during to each hole, and the ream amount of feeding is 0.3～0.5mm/r, and ream speed is 6～12m/min, and the hinge pin consumption is 0.1mm.
With processing Φ 36 circular cone pin-and-holes is example, and the cutter that is adopted sees the following form.
