Abstract
The utility model 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, the blade of described cutter protrudes cutter bar body, and described blade comprises a front end cutting edge and a rear end cutting edge.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.
Description
Technical field
The utility model relates to a kind of cutter for lathe or boring machine, is 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.
Utility model content
The purpose of this utility model is to provide a kind of chamfering knife bar, can carry out chamfering by improving under the prerequisite not overturning workpiece to the positive and negative that workpiece is holed.
For achieving the above object, the technical solution of the utility model 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 utility model is described in further detail:
Fig. 1 is the structural representation of the utility model chamfering knife bar embodiment;
Fig. 2 is the sectional structure schematic diagram of the utility model chamfering knife bar embodiment;
Fig. 3 is that the utility model falls the schematic diagram of the positive face of workpiece;
Fig. 4 is the schematic diagram in the utility model hole of falling back of work.
Detailed description of the invention
As depicted in figs. 1 and 2, the utility model chamfering knife bar, 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 preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; without departing from the concept of the premise utility; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
