Abstract
The utility model belongs to the metal surface Machining Technology, the inclined-plane, cylinder jacket inner bore surface mach fine boring squeezing knife tool its underpart that is used for that is proposed is main cutting edge (1), the right side is faced directly and is that wiper edges (3), the arc transition face between main cutting edge (1) and the wiper edges (3) are auxilliary cutting edge (2); Have the crush cones (4) that increases gradually along cutter direction of rotation circular arc on the wiper edges (3), the cone of crush cones (4) for cutting sth. askew and obtained to the awl end by the cone vertex of a cone, circular arc is the 25-35 degree at the bottom of the awl of this cone.The fine boring squeezing knife tool that the utility model proposed can push the cylinder sleeve bore surface in the cutting cylinder jacket inner bore surface, cylinder jacket inner bore surface metal tight ness rating is improved, thereby improve the wearability of cylinder liner internal wall, extruding rear region hardness improves HB40-HB60, tensile strength improves 45Mpa-65MPa, has prolonged the service life of engine; Its structural design is new reasonable.
Description
Technical field
The utility model belongs to the metal surface Machining Technology, relates generally to a kind of mach fine boring squeezing knife tool of cylinder jacket inner bore surface that is used for.
Background technology
The foundry engieering of cylinder jacket of diesel engine adopts centrifugal casting more at present, and it must cause the bore area inwall metal tight ness rating of cylinder jacket loose than the outer wall place; To the right boring process of casting exhaust hood cover bore area (inwall) also only is removal to allowance, can not do any improvement to the metal tight ness rating of cylinder liner internal wall; Because the cylinder jacket inner bore surface metal is loose, make engine in use cause cylinder jacket inner bore surface (inwall) to be easy to wear and tear and scrap too early.
Summary of the invention
The purpose of this utility model promptly is to propose a kind of mach fine boring squeezing knife tool of cylinder jacket inner bore surface that is used for, it can push cylinder jacket inner bore surface in the right boring cylinder jacket inner bore surface, the metal tight ness rating of cylinder liner internal wall is improved, thereby improve the wearability of cylinder liner internal wall, prolong the service life of engine.
The utility model takes following technical scheme to finish its invention task:
A kind of mach fine boring squeezing knife tool of cylinder jacket inner bore surface that is used for, the lower bevel of cutter is a main cutting edge, and the right side is faced directly and is wiper edges, and the arc transition face between main cutting edge and the wiper edges is auxilliary cutting edge; Have the crush cones that increases gradually along cutter direction of rotation circular arc on the wiper edges, the cone of crush cones for cutting sth. askew and obtained to the awl end by the cone vertex of a cone, circular arc is 25-35 degree at the bottom of the awl of this cone; The circular arc body of crush cones increases gradually along the direction of cutter rotation, can avoid crush cones that cylinder liner internal wall is formed and cut and guarantee the gradually pressurization extruding of crush cones to inboard wall of cylinder liner.
Described crush cones can be positioned at the bottom of wiper edges and have a determining deviation with auxilliary cutting edge.
The cutter that the utility model proposed is adding man-hour to cylinder jacket inner bore surface, utilize the main cutting edge of cutter to finish the processing of main cutting output, utilize auxilliary cutting edge to finish to remaining the cutting of processing capacity, utilize the crush cones on the wiper edges that the cylinder sleeve bore surface after cutting is pushed, cylinder jacket inner bore surface metal tight ness rating is improved, wiper edges forms main cutting edge, auxilliary cutting edge to the cylinder sleeve bore Surface Machining burr carries out smooth, utilizes wiper edges that crush cones is carried out smoothing to the micro-projection that the extruding of cylinder sleeve bore surface causes simultaneously.
The fine boring squeezing knife tool that the utility model proposed can push the cylinder sleeve bore surface in the cutting cylinder jacket inner bore surface, cylinder jacket inner bore surface metal tight ness rating is improved, thereby improve the wearability of cylinder liner internal wall, extruding rear region hardness improves HB40-HB60, tensile strength improves 45Mpa-65MPa, has prolonged the service life of engine; Its structural design is new reasonable.

The specific embodiment
Provide embodiment of the present utility model in conjunction with the accompanying drawings:
As Fig. 2, Fig. 3, shown in Figure 4, the inclined-plane, fine boring squeezing knife tool its underpart that proposes is a main cutting edge 1, the right side is faced directly and is wiper edges 3, arc transition face between main cutting edge and the wiper edges is auxilliary cutting edge 2, has crush cones 4 on the wiper edges 3, the circular arc of crush cones 4 increases gradually along the cutter direction of rotation, the cone of crush cones 4 for cutting sth. askew and obtained to the awl end by the cone vertex of a cone, and circular arc is 25-35 degree at the bottom of the awl of this cone.The circular arc body of crush cones 4 increases gradually along the direction of cutter rotation, can avoid crush cones that the pressurization gradually that cylinder liner internal wall forms cutting and 4 pairs of inboard wall of cylinder liner of assurance crush cones is pushed, crush cones 4 can be positioned at the bottom of wiper edges and have a determining deviation with auxilliary cutting edge.
The utility model process is: in to the cylinder jacket inner bore surface process, fine boring squeezing knife tool is done downward rectilinear motion when the cylinder jacket axis is done clockwise rotation; In this process, the main cutting edge 1 of cutter is finished the processing to big cutting output of cylinder jacket inner bore surface, auxilliary cutting edge 2 is finished the cutting of residue processing capacity, 4 pairs of cylinder jacket inner bore surfaces of the crush cones that has on the wiper edges push, cylinder jacket inner bore surface metal tight ness rating is improved, the burr that wiper edges 3 forms main cutting edge 1,2 pairs of cylinder jacket inner bore surface processing of auxilliary cutting edge back carries out smooth, simultaneously crush cones 4 is carried out smoothing in the micro-projection that the cylinder jacket inner bore surface extruding causes.
The situation of Fig. 5 after for right boring extruding cylinder jacket inner bore surface, the tight ness rating of obvious cylinder jacket inner bore surface metal is significantly improved.
