Description
【Technical field】
The present invention relates to the technical field of machining tool, particularly to a kind of boring for processing elongated cylinder bore
Knife.
【Background technology】
Cylinder block is the important composition part of hydraulic jack, and high-quality cylinder body can preferably ensure the close of hydraulic jack
Envelope property and service life.But it is faced with many difficulties in the little Long travel cylinder block of some diameters of processing, due to its cylinder
Body aperture is little, and boring bar used is thin, the in process easily phenomenon such as " allow knife ", vibration, leads to crudy poor, precision
Low；It is difficult to discharge further as chip, heat-sinking capability is poor, accelerates the abrasion of cutter.
【Content of the invention】
In view of this, for overcoming the deficiencies in the prior art, the present invention provides a kind of boring for processing elongated cylinder bore
Knife, its blade position is adjustable, and the range of work is wide, and machining accuracy is high；The bakelite guiding set up is cased with certain elasticity, both can avoid
Abrade machined surface, necessary guiding can be played again and require, improve the quality of processing.
For achieving the above object, technical scheme is as follows：
A kind of boring cutter for processing elongated cylinder bore, including knife bar and the blade being arranged on described knife bar, described
Knife bar side is provided with the square through hole matching with described blade, and described blade is arranged in described square through hole, described knife bar
End face is provided with trip bolt, and described blade is connected to described knife bar by described trip bolt, and described blade comprises front blade
With rear blade, described front blade is connected to described rear blade, and described rear blade side is provided with adjusting screw, described adjusting screw phase
Corresponding to described front blade one side, described knife bar one end is externally connected to bakelite fairlead, and described bakelite fairlead external diameter is little
In cylinder bore diameter 0.5mm-1.0mm to be processed, arrived by the cutting edge that described adjusting screw can accurately adjust described blade
The distance at described knife bar center, easy to use, the positioning of described bakelite fairlead, guiding avoid " allow knife " of knife bar to cause to process
The generation of the phenomenons such as precision is low, poor surface smoothness.
Further, described blade both sides are provided with relief angle α, and the angle of described relief angle α is 4 ° -6 °, and described relief angle is in boring
Play squeezing action during bits, make bore area fineness reach Ra1.6, accuracy class reaches iT7 level.
It is evenly arranged with twisted shape chip area, described chip area quantity is 4-6 part, by institute outside described bakelite fairlead
State the chip discharge that chip area will be processed, reduce the abrasion of cutter.
The structural principle of the present invention is：The phenomenons such as " allow knife " that exist for the little Long travel cylinder block of diameter, vibration,
Set up bakelite fairlead, so that the endoporus of processing is matched with described bakelite fairlead external diameter, play guiding, the effect of positioning, with
Improve its machining accuracy；The adjustable blade of setting, Adjustment precision is high, and usage range is wide.
The invention has the beneficial effects as follows, adjustment is convenient, and machining accuracy is high, improves the fineness of processing endoporus, extends
Cutting-tool's used life.
