Abstract
The utility model relates to a reaming and chamfering composite cutter. The cutter comprises a conical handle, a cutter head, a cutter handle and a spiral groove, wherein one end of the spiral groove is connected with one end of the cutter handle, and the other end of the spiral groove is connected with the cutter head; the other end of the cutter handle is connected with the conical handle; a reaming cutter and a chamfering cutter are arranged on the cutter head; the chamfering cutter is positioned at the rear end of the reaming cutter; and an included angle between the chamfering cutter and the reaming cutter is 45 degrees. The cutter has a simple structure, can improve processing accuracy and processing efficiency, and effectively reduces processing cost.
Description
Technical field
The utility model relates to the cutter that uses in a kind of machining, relates in particular to a kind of reaming and chamfering compound tool.
Background technology
High-precision hole in machine components adds man-hour, all need carry out the aperture chamfering to the aperture, and adding man-hour at present all is that reaming and aperture chamfering are separately carried out, and uses earlier cornish bit to carry out reaming, carries out chamfer machining after then cornish bit being replaced by rose reamer.Traditional processing method is that the first hole is processed is that reaming and aperture chamfering are carried out separately; Take two process tools, twice clamping, the processing mode of twice processing; Its working (machining) efficiency is low; And cause chamfering and reaming decentraction easily, make the chamfering in reaming aperture depart from, cause waste product and defect ware rate than higher.
Summary of the invention
The purpose of the utility model is exactly in order to solve deficiency of the prior art, provide a kind of simple in structure, can improve machining accuracy and a kind of reaming of raising labour efficiency, effectively cutting down finished cost and chamfering compound tool.
The technical scheme of the utility model is achieved in that a kind of reaming and chamfering compound tool; It comprises taper shank, cutter head, cutter handle, helicla flute; Helicla flute one end links to each other with an end of cutter handle, end links to each other with cutter head in addition, and cutter handle end in addition links to each other with taper shank, on cutter head, is provided with cornish bit and rose reamer; Rose reamer is positioned at the rear end of cornish bit, and the angle between rose reamer and the cornish bit is 45 degree.
The utility model has the advantages that: simple in structure, can improve machining accuracy and working (machining) efficiency, effectively cut down finished cost.
Description of drawings
Fig. 1 is the structural representation of the utility model reaming and chamfering compound tool.
Each sequence number among the figure: 1-cornish bit, 2-rose reamer, 3-helicla flute, 4-cutter handle, 5-cutter head, 6-taper shank.
The specific embodiment
As shown in Figure 1; A kind of reaming and chamfering compound tool, it comprises taper shank 6, cutter head 5, cutter handle 4, helicla flute 3, helicla flute 3 one ends link to each other with an end of cutter handle 4, end links to each other with cutter head 5 in addition; Cutter handle 4 end in addition links to each other with taper shank 6; On cutter head 5, be provided with cornish bit 1 and rose reamer 2, rose reamer 2 is positioned at the rear end of cornish bit 1, and the angle between rose reamer 2 and the cornish bit 1 is 45 degree.
During the utility model work; The taper shank 6 at the cutter hub rear portion of reaming and chamfering compound tool is connected with the main shaft of lathe; The cutter hub that drives reaming and chamfering compound tool that rotatablely moves of main shaft rotatablely moves; And then the cornish bit 1 that drives on the cutter head 5 of cutter front end rotatablely moves with rose reamer 2, and the cornish bit 1 that is positioned at foremost carries out reaming processing to the workpiece that clamps earlier, and chamfer machining is carried out in the aperture that is close to 2 pairs of reamings of rose reamer of its setting.Like this, because rose reamer 2 and concentric setting of cornish bit 1 one, and cornish bit 1 is positioned at the front end of rose reamer 2, therefore, guarantees carrying out carrying out chamfer machining when reaming is processed to clamping workpiece.And two step of reaming and chamfering operation is concentrated is a step, and No. one time clamping just can carry out bottom outlet reaming and aperture chamfer machining to other worker's workpiece, and both are concentric setting owing to cornish bit 1 and rose reamer 2; Its central axes; Therefore guarantee in the process that reaming overlaps with the chamfering center, avoid off-axis between reaming and the chamfering, improve machining accuracy and working (machining) efficiency; Improve the finished product rate of output, effectively cut down finished cost.
