Abstract
The invention belongs to process equipment for part processing, and relates to a novel insection hob. In the novel insection hob, a hole matched with a machine tool spindle is formed in center of a hob body; the cylindrical surface of the hob body comprises multiple parallel helical teeth; adjacent two helical teeth are staggered. The pitch of each helical tooth of the hob body is twice the pitch of a processed insection; each helical tooth is consistent with the processed insection in tooth shape. The helical angles of the helical teeth are 10-20 degrees. Compared with the prior art, the novel insection hob provided by the invention has the beneficial effects that the shortcomings of discontinuous cutting and unsmooth chip discharge, caused by small insection pitch and dense teeth of a straight-tooth insection hob, in processing are overcome, so that a novel tool which is steady in cutting, smooth in chip discharge and long in service life is provided. The production cost is reduced, and the working efficiency is improved.
Description
Technical field
The technological equipment that the invention belongs to part processing, relates to a kind of novel groove hob.
Background technology
The processing of high-strength material, lengthening close-toothed line is the difficult point in producing always, adopted in the past the processing of straight-tooth groove hob always, weak point is: because groove tooth pitch is little, cutter tooth level of confidentiality, there is the drawback that cutting is discontinuous, chip removal is obstructed in this cutter, tool wear is quite fast, and processing cost is high.
Summary of the invention
(1) goal of the invention: the present invention has overcome deficiency of the prior art, provides a kind of effective processing high-strength material, has lengthened the cutter of close-toothed line.
(2) technical scheme: in order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of novel groove hob, cutter center has the hole coordinating with machine tool chief axis, comprises the parallel spiral tooth in some roads on the cutter face of cylinder, and adjacent twice helical tooth side set is arranged.
The per pass helical tooth tooth pitch of described hob by two times of processing groove tooth pitch, per pass helical tooth profile of tooth is consistent with processed groove profile of tooth.
Described helical tooth helical angle is 10 degree-20 degree.
(3) beneficial effect
Compared with prior art, the invention has the beneficial effects as follows: solved straight-tooth groove hob groove tooth pitch little, cutter tooth is intensive cause add the drawback that cutting in man-hour is discontinuous, chip removal is obstructed, provide that a kind of stable cutting, chip removal are unobstructed, the new-type cutter of the long service life of cutter.Reduced production cost, increased work efficiency.
Accompanying drawing explanation
The present invention includes 4 figure, the accompanying drawing of these accompanying drawings is described as follows: Fig. 1 is former straight-tooth hob;
Fig. 2 is former hob profile of tooth enlarged drawing;
Fig. 3 is spiral side set hob;
Fig. 4 is spiral side set hob profile of tooth enlarged drawing;
Fig. 5 is groove hob working motion mode figure.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the present invention is described in further detail: a kind of novel groove hob, cutter center has the hole coordinating with machine tool chief axis, comprises the parallel spiral tooth in some roads on the face of cylinder, and adjacent twice helical tooth side set is arranged.
Per pass helical tooth tooth pitch by two times of processing groove tooth pitch, per pass helical tooth profile of tooth is consistent with processed groove profile of tooth.
Described helical tooth helical angle is 15 degree.Described hob anterior angle is 5 degree, and relief angle teeth back-off amount is 3mm.
Parallel spiral tooth make processing more continuously, side set arranges and makes chip removal more unobstructed, effectively avoids the little tooth pitch of straight-tooth groove hob, drawback that cutter tooth is intensive, the service life of improving cutter.
Use when of the present invention, this groove hob is used on sleeping milling machine tool, and the hole that center cutter is opened, is to coordinate with machine tool chief axis, cutter and lathe are linked together, and power is cut in transmission.Part to be processed is located, is clamped on sleeping milling machine tool work top, makes processed plane parallel with machine tool chief axis; Start lathe, groove hob rotates around machine tool chief axis, simultaneously along laterally doing feed motion, machined part.
Claims (3)
1. a novel groove hob, cutter center has the hole coordinating with machine tool chief axis, it is characterized in that, comprises the parallel spiral tooth in some roads on the cutter face of cylinder, and adjacent twice helical tooth side set is arranged.
2. a kind of novel groove hob as claimed in claim 1, is characterized in that, the per pass helical tooth tooth pitch of described hob by two times of processing groove tooth pitch, per pass helical tooth profile of tooth is consistent with processed groove profile of tooth.
3. a kind of novel groove hob as claimed in claim 1, is characterized in that, described helical tooth helical angle is 10 degree-20 degree.
