Abstract
The utility model relates to a helical tooth pre-shaving tip relief pinion cutter comprising an inner hole. A plurality of cutting teeth are distributed on the radial direction of the inner hole, a scrape-containing groove is arranged between the cutting teeth; the cutting edge of each cutting tooth consists of a cutter tooth side surface, a cutter tooth front edge surface and a cutter tooth top edge surface; the cutter teeth side surface consists of a tooth top bulge part, a tooth root tip relief part and an involute tooth surface. In the helical tooth pre-shaving tip relief pinion cutter, the normal front angle of the cutter tooth is 5 degrees, and the top rear angle of the cutter tooth is 6 degrees. The helical tooth pre-shaving tip relief pinion cutter is suitable for processing a gear by coarse gear shaping and precise gear shaping, and simultaneously can process gear tooth root and gear top chamfer, and the processing time of the gear can be saved, the tools used for processing gear are reduced, the processing cost of the gear is lowered, and the processing precision of the gear is improved.
Description
Technical field
The utility model relates to a kind of cutting element, relates in particular to a kind of helical teeth preshaving tip relief pinion cutter that is used for thick, the finishing tooth wheel on the shaping machine.
Background technology
Present traditional helical gearshaper cutter, can only process general helical gear, but uproot or avoid fillet curve to interfere and tooth top during along tooth length direction chamfering when the gear that needs processing requires to have root, after adding work gear by general helical gearshaper cutter, need design the tooth top rose reamer again, on special purpose machine tool, process, perhaps carry out manual processing with other instruments.Therefore, for Gear Processing, the processing of its gear teeth needs two lathes, two kinds of cutters so earlier with behind the intact gear teeth of Gear Processing, also will be put into processing tooth top chamfered part on another lathe, do like this, increased the secondary clamping of gear, again the Gear Processing precision has been had certain influence, not only increased the processing cost of gear but also increased process time of gear.And can not guarantee the machining accuracy of gear, thus influence the assembling of gear, influence the gear meshing precision, if processing by hand, it is consistent that gear tooth both sides chamfering is not easy to reach.Therefore, design a kind of comprehensive new gear process tool and become the primary key technical problem that solves in the Tool Design.
Summary of the invention
The utility model helical teeth preshaving tip relief pinion cutter technical problem to be solved is to overcome a prior art difficult problem, provides a kind of and is suitable for thick (preshaving, scrape before), smart Gear Shaping gear and processes Gear Root simultaneously and the helical teeth preshaving tip relief pinion cutter of tooth top chamfering.
The technical solution of the utility model is: a kind of helical teeth preshaving tip relief pinion cutter, comprise endoporus, and on the direction of endoporus aperture, several cutting teeths are arranged circumferentially, offer chip pocket between the described cutting teeth; The cutting edge of each cutting teeth is by the cutter tooth side, the cutter tooth lip surface, and cutter tooth top sword face is formed; Described cutter tooth side is made up of tooth top jut and tooth root tip relief part and involute flank.
Aforesaid helical teeth preshaving tip relief pinion cutter, the cutter tooth normal rake is 5 °, cutter tooth tooth top relief angle is 6 °.
Owing to adopt said structure, the utlity model has following beneficial effect:
1, the utility model adopts the cutting movement of helical teeth preshaving tip relief pinion cutter and gear to learn and theory of metal cutting, by generate processing, through the processing of feeding several times, once finishes the root of gear and uproots and the tooth top chamfering.
2, because the utility model structural design of adopting helical teeth preshaving tip relief pinion cutter, saved the process time and the equipment of gear, reduced the number of cutters of gear, improved the machining accuracy of gear.Reduced the processing cost of gear.Avoided the inconsistent capable problem of manual chamfering.
3, the utility model is applied widely, is not only applicable to the involute profile of modular system or pitch system.Be specially adapted to internal gear and duplicate gear.And, be suitable for thick (preshaving, scrape before) Gear Shaping gear, be convenient to processing and detection, long service life.
4, the utility model helical teeth preshaving tip relief pinion cutter is under the condition that effectively cutting parameter allows, and it can repeatedly use, and is easy to use flexible.
5, the reconditioning of the utility model helical teeth preshaving pinion cutter is simple, and is identical with common pinion cutter sharpening, and a reconditioning cutter tooth lip surface need not acquired special equipment.On cutter and tool grinding machine, utilize special fixture reconditioning cutter tooth lip surface to get final product.
Description of drawings
Fig. 1 is the cutter tooth distribution schematic diagram of the utility model pinion cutter.
Fig. 2 is the cutter tooth side schematic view among Fig. 1.
Fig. 3 is the angle schematic diagram of the utility model pinion cutter.
Mark the following drawings mark thereon in conjunction with the accompanying drawings: 1, endoporus, 2, cutting teeth, 3, chip pocket, 4, the cutter tooth side, 5, the cutter tooth lip surface, 6, cutter tooth top sword face.
The specific embodiment
Referring to Fig. 1, a kind of helical teeth preshaving tip relief pinion cutter comprises endoporus 1, on endoporus 1 aperture direction several cutting teeths 2 is arranged circumferentially, offers chip pocket 3 between the described cutting teeth 2; Referring to Fig. 2, the cutting edge of each cutting teeth 2 is by cutter tooth side 4, cutter tooth lip surface 5, and cutter tooth top sword face 6 is formed; Described cutter tooth side 4 is made up of tooth top jut and tooth root tip relief part and involute flank.
Referring to Fig. 3, aforesaid helical teeth preshaving tip relief pinion cutter, cutter tooth normal rake α is 5 °, cutter tooth tooth top relief angle β is 6 °.
When helical teeth preshaving tip relief slotting cutter tooth surface part tooth top coign adds the work gear root, formation is uprooted, at the bottom of guaranteeing gear shaver the gear shaver tooth top not bumping tooth in shave processing, perhaps avoid fillet curve to interfere, guarantee the effective involute of gear teeth face, the gear teeth tips chamfered part is partly processed in the tip relief of pinion cutter tooth root.
Master operation:
1, grind the flank of helical teeth preshaving tip relief pinion cutter.
2, the end face of mill helical teeth preshaving tip relief pinion cutter.
3, grind the lip surface of helical teeth preshaving tip relief pinion cutter.
Different during the tooth flank surface grinding with common pinion cutter, common pinion cutter is just qualified as long as the whole tooth surface involute is reached the drawing requirement, and will the grinding flank of tooth involute part during aforesaid helical teeth preshaving tip relief pinion cutter grinding also want the tip relief of grinding tooth root partly and tooth top preshaving part, at first flank of tooth involute is partly ground, the tooth top coign part of regrinding out, grind tooth root tip relief part at last, the grinding of tooth root tip relief part is crucial, its tip relief height is found out tip relief point highly in the drawings according to gear and pinion cutter pitch curve, the slotting cutter tooth surface shape of during grinding the wheel grinding face being rested and reorganized out.Detection method detects the tip relief height at universal tool-measuring microscope, detects tip relief position involute and launch arc length on gear measurement machine.
