Abstract
The utility model relates to a kind of detachable roller flange perforating cutter, and comprise handle of a knife and rhombohedral insert, handle of a knife body is bent into 45 ~ 60 ° of angles, and the head of handle of a knife is cutter head installation portion, and rhombohedral insert is fixed on cutter head installation portion by trip bolt; Four limits of rhombohedral insert all offer blade, and the acute angle of rhombohedral insert is 45 °, and rhombohedral insert is carbide bit.Compared with prior art, the utility model has that structure is simple, easy to use, working (machining) efficiency is high, machining accuracy advantages of higher.
Description
Technical field
The utility model relates to a kind of cutter, especially relates to a kind of detachable roller flange perforating cutter.
Background technology
Roller structure as shown in Figure 1, comprises roller body 1, is fixed on the roller flange 2 at roller body 1 two ends, offers endoporus 3 in roller flange 2 inside.When roller makes, need to fix roller flange at the two ends of roller body, and perforate is carried out to roller flange, make to form endoporus in the middle of roller flange, and then fine finishining is carried out to endoporus, process the keyway in endoporus.
As shown in Figure 2, traditional perforate lathe tool, all adopts the one numerical control knife 4 of 45 degree, its cutter and handle of a knife welded together, can not dismantle.In process, point of a knife can wear and tear or forge a knife, and at this moment whole, cutter must be removed, carry out reconditioning, can reuse.But because the operative skill of employee is different, also difference is existed, so sharpening program has become bottleneck for the level of whetting a knife.Beginner often due to can not whet a knife or sharpening level lower, will inefficiency be caused, the situation that quality cannot ensure.Circular runout large and easy machining deformation when the machining tool of existing roller flange uses.
Utility model content
The purpose of this utility model be exactly in order to overcome above-mentioned prior art exist defect and the detachable roller flange perforating cutter that a kind of structure is simple, easy to use, working (machining) efficiency is high, machining accuracy is high is provided.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of detachable roller flange perforating cutter, comprise handle of a knife and rhombohedral insert, described handle of a knife body is bent into 45 ~ 60 ° of angles, and the head of handle of a knife is cutter head installation portion, and described rhombohedral insert is fixed on cutter head installation portion by trip bolt.
The middle part of described rhombohedral insert offers screw hole.
Four limits of described rhombohedral insert all offer blade.
The acute angle of described rhombohedral insert is 45 °.
Described rhombohedral insert is carbide bit.
Described cutter head installation portion offers the rhombus mounting groove with rhombohedral insert form fit, in rhombus mounting groove, offer screw hole.
Compared with prior art, the utility model has the following advantages and beneficial effect:
(1) handle of a knife and cutter head separate by the utility model, and by the fastening installation of trip bolt, are so just beneficial to the replacing of cutter head, when needs tool changing, only screw need be unclamped, by bit replacing, decrease that employee frequently whets a knife, tool changing, reduce time waste.
(2) handle of a knife body is bent into 45 ~ 60 ° of angles by the utility model, when being connected on numerical controlled machinery by handle of a knife end, because the angle of handle of a knife body is arranged, is convenient to extend into roller flange inside and carries out interior hole machined.
(3) cutter head is arranged to rhombus, and blade is all offered in four limits, the utilization rate like this for cutter head improves further, and can make processing top or below time, do not need to change cutter.
(4) acute angle of cutter head is arranged at 45 °, be conducive to improving machining accuracy.
Accompanying drawing explanation
Fig. 1 is the structural representation of roller;
Fig. 2 is the structural representation of traditional drilling tool;
Fig. 3 is detachable roller flange perforating cutter structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment
A kind of detachable roller flange perforating cutter, as shown in Figure 3, comprise handle of a knife 5 and rhombohedral insert 6, handle of a knife 5 body is bent into 45 ~ 60 ° of angles, the head of handle of a knife 5 is cutter head installation portion 51, cutter head installation portion 51 offers the rhombus mounting groove with rhombohedral insert 6 form fit, in rhombus mounting groove, offer screw hole.The middle part of rhombohedral insert 6 offers screw 7 hole.Four limits of rhombohedral insert 6 all offer blade.The acute angle of rhombohedral insert 6 is 45 °.Rhombohedral insert 6 is carbide bit 6.Rhombohedral insert 6 is fixed on cutter head installation portion 51 by trip bolt 7.
Changed into by original replacing numerical control handle of a knife and change numerical control cutter head, without the need to reconditioning, only need change cutter head and just can use, main is that efficiency improves one times than before nearly, and operation is lighter, quick, and machining accuracy is higher.
Above-mentioned is can understand for ease of those skilled in the art and use utility model to the description of embodiment.Person skilled in the art obviously easily can make various amendment to these embodiments, and General Principle described herein is applied in other embodiments and need not through performing creative labour.Therefore, the utility model is not limited to above-described embodiment, and those skilled in the art, according to announcement of the present utility model, do not depart from improvement that the utility model category makes and amendment all should within protection domain of the present utility model.
Claims (6)
1. a detachable roller flange perforating cutter, is characterized in that, comprise handle of a knife and rhombohedral insert, and described handle of a knife body is bent into 45 ~ 60 ° of angles, and the head of handle of a knife is cutter head installation portion, and described rhombohedral insert is fixed on cutter head installation portion by trip bolt.
