Detailed Description
Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
As shown in fig. 1, it is a schematic structural diagram of the double-sided chamfering and drilling integrated cutter provided by the present invention. The double-sided chamfering and drilling integrated cutter comprises a cutter body 10 and a cutter handle 20 which is integrally formed with the cutter body 10. It is contemplated that the double-sided chamfer and bore integral cutter further includes other functional modules, such as a shank holder, etc., but these are well known to those skilled in the art and will not be described in detail herein.
The blade body 10 includes a tip section 11, a cutting section 12 connected to the tip section 11, and a relief section 13 connected to the cutting section 12. The nose section 11 may be conical for pre-drilling and positioning the double chamfer drill integral tool during drilling. The cutting section 12 may include cutting edges and flutes, and the cutting section 12 is used to cut the desired through-hole. The cutting segment 12 further includes a reverse chamfer edge 14 disposed on the cutting segment 12 and close to one side of the relief groove segment 13, and the size and angle of the chamfer of the reverse chamfer edge 14 can be determined according to a workpiece to be machined. The reverse chamfering edge 14 is used for chamfering the other side of the workpiece in the tool retracting process after the double-sided chamfering tool completes drilling and chamfering on one side. The diameter of the outer circular surface of the relief groove section 13 is smaller than the diameter of the outer circular surface of the cutting section 12, and the diameter of the outer circular surface of the relief groove section 13 is smaller than the diameter of the outer circular surface of the tool holder 20, so that the reverse chamfer edge 14 can be formed on the cutting section 12 and the forward chamfer edge 21 can be formed on the tool holder 20 as follows. The relief groove section 13 is cylindrical and may include chip flutes.
The shank 20 may be cylindrical for connection to a clamping device. The shank 20 may be an alloy tool steel or a high speed steel. The shank 20 may be integrally formed with the blade 10. The tool shank 20 comprises a positive chamfer edge 21 arranged on the tool shank 20 and close to one side of the tool withdrawal groove section 14. The size and angle of the chamfer of the positive chamfer edge 21 can be determined according to the workpiece to be machined. The positive chamfering edge 21 is used for chamfering one side of the workpiece after the double-sided chamfering and drilling integrated cutter completes drilling. The size of the chamfer of the forward chamfer edge 21 may be equal to the size of the chamfer of the reverse chamfer edge 14 and the angle of the chamfer of the forward chamfer edge 21 may be equal to the angle of the chamfer of the reverse chamfer edge 14, so that a workpiece with the same size and angle of double-sided chamfer may be poured. The shaft diameter of the tool holder 20 may be equal to the shaft diameter of the outer circumferential surface of the cutting section 12, so that when chamfering is performed on both sides, the double-sided chamfering and drilling integrated tool may rotate around only one fixed central shaft to complete double-sided chamfering. The shank 30 may also include a rounded clamping portion. The clamping portion is used for fixedly mounting the tool shank 30 and the clamping device.
The working principle of the double-sided chamfering and drilling integrated cutter is as follows: in the feed process, a hole is pre-drilled in the tool tip section 11 of the tool body 10, and then the hole is drilled in the cutting section 12. When the drilling is completed, the cutting is continued, and when the cutting reaches the positive chamfering edge 14, the workpiece is chamfered by the positive chamfering edge 14. After the chamfering at one side is finished, the double-sided chamfering and drilling integrated tool starts to retract, when the tool retracts to the reverse chamfering edge 21, the reverse chamfering edge 21 chamfers the workpiece at the other side, and after the chamfering is finished, the tool retracts continuously, namely, one-time drilling and double-sided chamfering are finished
Compared with the prior art, the utility model provides an integrative sword of two-sided chamfer drilling is through set up on the blade 10 blade tip section 11 cutting section 12 is close to one side of retreating tool groove section 13 sets up reverse chamfer sword 14 handle of a knife 20 is close to one side of retreating tool groove section 14 sets up forward chamfer sword 21. And the shaft diameter of the cutting section 12 is greater than that of the tool withdrawal groove section 13, and the shaft diameter of the tool holder 20 is greater than that of the tool withdrawal groove section 13, so that when the double-sided chamfering and drilling integrated tool is fed, the tool point section 11 is used for pre-drilling, and the cutting section 12 is used for cutting to complete drilling. After the drilling is finished, the drilling is continued, and the chamfer on one side is chamfered by the positive chamfer edge 14. After the chamfering at one side is finished, the double-sided chamfering and drilling integrated tool retracts, when the tool retracts to the position of the reverse chamfering edge 21, the reverse chamfering edge 21 is used for chamfering the other side, after the chamfering is finished, the tool retracts continuously, namely, one-time drilling and double-sided chamfering are finished, and therefore the double-sided chamfering and drilling are finished at one time by the double-sided chamfering and drilling integrated tool, and machining efficiency is high.
The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention, and any modification, equivalent replacement or improvement within the spirit of the present invention is encompassed by the claims of the present invention.
