Abstract
The invention discloses a chamfer cutter bar. The chamfer cutter bar comprises a cutter bar body, wherein a cutter is arranged at the front end of the cutter bar body, a gap for installing the cutter is formed in the front end of the cutter bar body, the cutter is fixed to the gap through a hexagon socket cap screw, and a cutting edge of the cutter protrudes out of the cutter bar body and comprises a front end cutting edge body and a rear end cutting edge body. Because the cutter is arranged on the cutter bar body, the cutting edge of the cutter protrudes out of the cutter bar body, the front end cutting edge body of the cutting edge is used for performing chamfering on the front sides of holes of workpieces, and in other words, the cutting edge body at the end, far away from a cutter bar base, of the cutting edge is used for machining. The rear end cutting edge body of the cutting edge is used for performing chamfering on the back sides of the holes of the workpieces, and in other words, the whole cutting edge penetrates through the holes of the workpieces and the cutting edge body at the end, close to the cutter bar base, of the cutting edge is used for machining. The chamber cutter is used for chamfering, the chamfering efficiency is improved, and the problem that chamfering cannot be performed on the back sides of the holes of some workpieces is avoided.
Description
Technical field
The present invention relates to a kind of cutter for lathe or boring machine, be specifically related to a kind of chamfering knife bar.
Background technology
In the processing of modern mechanical part, requirement must cross the part of hole machined, sub-assembly, and Hole chamfering crossed by complicated body conventional cone bed.But aperture is general all relatively large, lathe also can adopt longer knife bar to process some can the chamfering of clamping rotating body parts, at present, general chamfering tool can only carry out chamfering to the boring front of workpiece, and the chamfering at the Workpiece boring back side needs workpiece turn-over to realize.
Summary of the invention
The object of the present invention is to provide a kind of chamfering knife bar, under the prerequisite not overturning workpiece, chamfering can be carried out to the positive and negative that workpiece is holed by improving.
For achieving the above object, technical scheme of the present invention is: chamfering knife bar, comprise cutter bar body, described cutter bar body front end is provided with cutter, described cutter bar body front end is provided with the gap of mounting cutter, described cutter is fixed on gap place by hexagon socket cap head screw, and the blade of described cutter protrudes cutter bar body, and described blade comprises a front end cutting edge and a rear end cutting edge.
When adopting technique scheme, owing to being provided with cutter on knife bar, and the blade of cutter protrudes knife bar, is the front end cutting edge utilizing blade during positive to the hole of workpiece like this surface chamfer, namely away from one end cutting edge processing of knife bar seat.And during the hole back face chamfer of processing work, be the rear end cutting edge that make use of blade, by whole blade through workpiece hole, utilize one end cutting edge processing near knife bar seat.Adopt this chamfering tool chamfering, improve the efficiency of chamfering, avoid the problem that some part back side Hole chamfering cannot fall.
Further, the blade of described cutter protrusion knife bar is symmetrically distributed in the both sides of knife bar.The rotation that above-mentioned setting can make full use of knife bar carries out chamfering to hole.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of chamfering knife bar embodiment of the present invention;
Fig. 2 is the sectional structure schematic diagram of chamfering knife bar embodiment of the present invention;
Fig. 3 is that the present invention falls the schematic diagram of the positive face of workpiece;
Fig. 4 is the schematic diagram in the present invention hole of falling back of work.
Detailed description of the invention
As depicted in figs. 1 and 2, chamfering knife bar of the present invention, comprises knife bar 1, and the front end of knife bar 1 offers the gap of mounting cutter 2, and cutter 2 is fixed on gap place by hexagon socket cap head screw 3.The blade 21 of cutter 2 protrudes knife bar 1, and described blade 21 comprises a front end cutting edge and a rear end cutting edge.Owing to being provided with cutter 2 on knife bar 1, and the blade 21 of cutter 2 protrudes knife bar 1.The blade 21 that cutter 2 protrudes knife bar 1 is symmetrically distributed in the both sides of knife bar 1, and the rotation that can make full use of knife bar 1 carries out chamfering to hole.As shown in Figure 3, be the front end cutting edge utilizing blade 21 during surface chamfer positive to the hole of workpiece, namely away from one end cutting edge processing of knife bar seat.As shown in Figure 3, during the hole back face chamfer of processing work, be the rear end cutting edge that make use of blade 21, by whole blade 21 through workpiece hole, utilize one end cutting edge processing near knife bar seat.Adopt this chamfering tool chamfering, improve the efficiency of chamfering, avoid the problem that some part back side Hole chamfering cannot fall.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; without departing from the inventive concept of the premise; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
Claims (2)
