The boring machine knife holder comprises a cylinder-shaped knife bar for clamping a knife tool, wherein a circular hole is formed in the center of the front end of the knife bar; a central drill bit is fixed in the circular hole; knife blades are symmetrically fixed on two sides of the central drill bit and at the front end of the knife bar; knife edges of the knife blades are indented for a certain distance from the central drill bit; one end of each knife edge is abutted against the central drill bit; fan-shaped fixing blocks for fixing the knife blades are symmetrically arranged at the front end of the knife bar; inner concaves matched with the knife blades in shape are formed in the side surfaces of the fan-shaped fixing blocks; the knife blades are fixed in the inner concaves; the knife edges are higher than the front ends of the fan-shaped fixing blocks; the knife blades are fixed on the fan-shaped fixing blocks through screws; a counter bored hole is radially formed in the knife bar, and a radial screw penetrates into the counter bored hole to fix the central drill bit; and a counter bored hole is axially formed in the tail part of the knife bar, and an axial screw penetrates into the counter bored hole to fix the central drill bit. The boring machine knife holder has the benefits of improving the product processing precision, improving the work efficiency and reducing the cost.
Description
Technical field
The utility model relates to the cutting element of machining, especially relates to the boring machine knife rest of bent axle processing.
Background technology
In the bent axle mechanical processing process, often need process the end face centering again of clearing earlier to the end face of bent axle; Because of lathe can not the clamping bent axle, thus can't accomplish through lathe, usually; Select for use milling machine earlier end face to be milled processing, milled behind the end face machining center hole on numerical control borer again, two equipment of processing needs could be accomplished; Through twice loading and unloading, owing to have assembling and equipment error, so the perpendicularity of centre bore and axial end is poor; Have influence on the quality of product, workload is big simultaneously, and production efficiency is lower.
The utility model content
The utility model provides a kind of boring machine knife rest that is used for bent axle processing in order to overcome above-mentioned deficiency, can the two procedures of end face milling and boring once be accomplished on boring machine.
The technical scheme of the utility model is:
A kind of boring machine knife rest that is used for bent axle processing; Comprise the cylinder shape knife rod that is used for the clamping cutter; It is characterized in that: described knife bar front end center offers circular hole, is fixed with center bit in this circular hole, the both sides of said center bit and knife bar front end symmetry be fixed with blade; The blade position of said blade is than head indentation one segment distance of said center bit, and an end of said blade is near center bit.
Preferably; Said knife bar front end is provided with the fan-shaped fixed block that is used for fixing said blade of symmetry; The side of this fan-shaped fixed block is provided with the indent with said blade shapes coupling, and described blade is fixed on described indent, and described blade exceeds the front end of said fan-shaped fixed block.
The purpose of indent is set, and is that said knife bar is that blade provides radially and axial holding power.
Whet a knife for ease sheet or replacing, described blade is fixed on the fan-shaped fixed block through screw.
As preferably, described blade is triangular in shape, and blade is perpendicular to the axial location setting of center bit.
For can be after processing; It is smooth that the end face of work piece keeps; Remove the vestige of said blade and center bit joining place; Described center bit is by boring columniform anterior drill bit, can boring conical middle part drill bit and the clamping rear portion is formed, and the said blade that symmetry is installed is provided with by the position of the distance between two blades less than the same cutting face diameter of center bit, and said blade is positioned at the position, drill bit both sides, middle part of center bit.
Safeguard that for ease be convenient for changing, knife bar radially is provided with a counterbore, penetrates this counterbore fixed center drill bit by radial screw; The afterbody of said knife bar is axially arranged with a counterbore, penetrates this counterbore fixed center drill bit by axial bolt
The utlity model has the raising processing precision of products, increase work efficiency, the beneficial effect that reduces cost.
Description of drawings
Fig. 1 is used for the overall structure sketch map of the boring machine knife rest of bent axle processing for the utility model.
The specific embodiment
Combine accompanying drawing that the utility model is further described at present:
As shown in Figure 1; A kind of boring machine knife rest that is used for bent axle processing comprises the cylinder shape knife rod 5 that is used for the clamping cutter, and circular hole is offered at knife bar 5 front end centers; Be fixed with center bit 1 in this circular hole; The both sides of center bit 1 and knife bar 5 front ends symmetry be fixed with blade 21 and blade 22, the blade position of blade 21 and blade 22 is than head indentation one segment distance of center bit 1, and an end of blade is near center bit 1.
The both sides of circular hole; Be provided with the fan-shaped fixed block 51 and fan-shaped fixed block 52 that are used for fixing blade 21 and blade 22 of symmetry at knife bar 5 front ends; The side of this fan-shaped fixed block 51 and fan-shaped fixed block 52 is provided with the indent with blade 21 and 22 form fit, and blade 21 is triangular in shape with blade 22, and blade is perpendicular to the axial location setting of center bit 1; The bottom of this indent is provided with the cavity that can stretch into blade 21 and blade 22 the top of the horns; Can guarantee that leg-of-mutton two limits of blade 21 and blade 22 and two limits of indent coincide, blade 21 is fixed on indent with blade 22 through screw 3, and blade exceeds the front end face of fan-shaped fixed block 51 and fan-shaped fixed block 52.
Knife bar 1 radially is provided with a counterbore, penetrates this counterbore fixed center drill bit 1 by radial screw 4.
The afterbody of knife bar 1 is axially arranged with a counterbore, penetrates this counterbore fixed center drill bit by axial bolt 6.
Utilize the knife rest machining crankshafts end face of present embodiment, the disposable punching and the crankshaft end-face of clearing just can accomplished simultaneously is owing to disposable completion, so the perpendicularity of centre bore and axial end is good.
