Abstract
The utility model discloses a cutter of chamfer can be carried out again to these hole both ends in processing hole even is free sword section between centre gripping section and drilling section, the diameter of empty sword section is less than the diameter of drilling section, the diameter of drilling section is less than the diameter of centre gripping section, in the junction of centre gripping section with empty sword section, be equipped with and pierce end chamfer cutting edge, in the junction of drilling section with empty sword section, be equipped with and drill out end chamfer cutting edge. After drilling processing was accomplished in the work, control centre gripping section moved down with the end chamfer cutting edge that pierces of empty sword section junction, cuts the chamfer to the hole week arris deckle edge that pierce the end to the adjustment digit control machine tool drives central displacement to the chamfer size of setting for in the relative spare part processing hole in center of cutter, the control cutter shift up drive drilling section and empty sword section junction drill out end chamfer cutting edge, carry out the circular interpolation chamfer to the hole week arris deckle edge that drill out the end. Realized the disposable processing to hole and both ends chamfer, improved production efficiency and reduced manufacturing cost.
Description
Technical field
The utility model relates to cutting tool; Be specifically related to a kind of machining hole can carry out again chamfering cutter to these two ends, hole.
Background technology
After in prior art, the hole machined of parts completes, usually will piercing end and getting out end and carry out chamfering this hole, remove the corner angle burr of hole two end periphery, so that the perforation of connector is installed.Shortcomings: one is when carrying out chamfering to two ends, described hole, and operating personnel usually will be arranged to adopt special equipment and cutter to process, significantly reduces production efficiency and adds production cost.Two is the chamferings to special-shaped parts connecting hole, and due to the restriction by described component structural space, when carrying out the hole peripheral chamfer getting out end (as shown in Figure 4), operation processing is very difficult.
Utility model content
For the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of machining hole can carry out again the cutter of chamfering to these two ends, hole, is intended to realize process operation convenient and swift, to reach the object enhancing productivity and reduce production cost.
For achieving the above object, the technical solution of the utility model is achieved in that this machining hole can carry out again the cutter of chamfering to these two ends, hole, comprises gripping section and drilling section; It is between described gripping section and drilling section, be connected with sky cutter section; The diameter of described empty cutter section is less than the diameter of drilling section; The diameter of described drilling section is less than the diameter of gripping section; In the junction of described gripping section and described empty cutter section, be provided with and pierce chamfer blade; In the junction of described drilling section and described empty cutter section, be provided with and get out chamfer blade.
Preferably, described chamfered cutting edge is the wherein a kind of of oblique line shape, dome arcuation and concave arc shape.
Preferably, tilt angle alpha=30 at described oblique line shape chamfered cutting edge counter-knife center are ° to 60 °.
Preferably, described drilling section is straight trough shape or spiral channel-shaped.
The utility model is by taking said structure, during work, while after parts Drilling operation is completed, the chamfer blade that pierces controlling described gripping section and empty cutter section junction moves down, cutting chamfering is carried out to the hole edges of the periphery burr piercing end, and adjust the chamfer dimesion of the center displacement to setting in the Relative Zero component processing hole, center of Digit Control Machine Tool carry its tools, what control that shipper pole on cutter moves drilling section and empty cutter section junction gets out chamfer blade, carries out circular interpolation chamfering to the hole edges of the periphery burr getting out end.Complete the disposable processing to hole and two chamfers thereof quickly and easily.Compared with the existing technology, effectively improve production efficiency and significantly reduce production cost.
Accompanying drawing explanation
Fig. 1 is the view of a kind of embodiment of the utility model.
Fig. 2 is the utility model Fig. 1 left view.
Fig. 3 is that the utility model carries out the schematic diagram of two ends chamfering to common parts hole machined.
Fig. 4 is that the utility model carries out the schematic diagram of two ends chamfering to special-shaped parts hole machined.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model principle and feature are described in detail.Should illustrate: example, only for explaining the utility model, does not form the restriction to the utility model protection domain.
This machining hole can carry out again the cutter (shown in Fig. 1, Fig. 2) of chamfering to these two ends, hole, comprise gripping section and drilling section; It is connected with sky cutter section 2 between described gripping section 3 and straight trough shape drilling section 1; The diameter of described empty cutter section is less than the diameter of drilling section 1; The diameter of described drilling section is less than the diameter of gripping section 3; In the junction of gripping section and empty cutter section, be provided with oblique line shape and pierce chamfer blade; In the junction of drilling section and empty cutter section, be provided with oblique line shape and get out chamfer blade.Tilt angle alpha=45 ° (shown in Fig. 1) at described oblique line shape chamfered cutting edge counter-knife center.According to different processing requests, described chamfered cutting edge can also be dome arcuation or concave arc shape; Described drilling section 1 can also be spiral channel-shaped (not shown).The diameter of the present embodiment drilling section 1 is 12.5 millimeters, and the diameter of empty cutter section 2 is 8 millimeters, and the diameter of gripping section 3 is 16 millimeters.
During work, gripping section 3 of the present utility model is fixed on the drilling chuck of Digit Control Machine Tool, control drilling chuck rotation work and move down, the parts that drilling section 1 pair of lathe is installed are driven to carry out the drilling processing (shown in Fig. 3) in hole, hole drilling machines rear cutter to be continued to move down, chamfer blade is pierced with the oblique line shape of empty cutter section 2 junction by described gripping section 3, after the hole edges of the periphery burr piercing end are carried out cutting chamfering to the size of setting, control empty cutter section 2 return in machining hole.The off-centring of the center Relative Zero member apertures of adjustment Digit Control Machine Tool carry its tools is to the chamfer dimesion set, on control cutter, shipper pole moves drilling section 1 and gets out chamfer blade with the oblique line shape of empty cutter section 2 junction, carries out circular interpolation chamfering (shown in figure 3) to the hole edges of the periphery burr getting out end.The hole peripheral chamfer getting out end is complete, and the center controlling cutter is repositioned to the center in hole, controls drilling section 1 shifts out in hole, completes the disposable processing to hole and two chamfers thereof quickly and easily.Especially, when the hole periphery special-shaped parts connecting hole being got out to end carries out cutting chamfering, operate more convenient (shown in Fig. 4).
The above is only preferred embodiment of the present utility model.Be noted that for those of ordinary skill in the art; with substantially identical means; realize substantially identical function; reach substantially identical effect; without the need to other technical characteristic just obviously associated through creative work; can also replace the modification and/or improvement of making several basic same way, these changes should be considered as equivalent feature, within the protection domain all belonging to the utility model patent.
