Abstract
The utility model discloses pre-grinding hob, relate to machining tool, be specifically related to a kind of improvement opportunity of pre-grinding hob structure of machining gears.Comprise hobboing cutter cutter head and knife bar; There is micro-cone mandrel knife bar front end, micro-cone mandrel and knife bar integrative-structure, and micro-cone mandrel front end is the small end of taper; Have micro-taper hole in hobboing cutter cutter head, hobboing cutter cutter head is installed on micro-cone mandrel, and micro-taper hole coordinates with micro-cone mandrel, and the tapering of micro-taper hole and micro-cone mandrel is 1:85-90.The utility model solves the problem that existing pre-grinding hob secondary clamping can lose precision.
Description
Technical field
The utility model relates to machining tool, is specifically related to a kind of improvement opportunity of pre-grinding hob structure of machining gears.
Background technology
Pre-grinding hob refers to that, when machining gears, toothed section stays mill surplus, and roller seating space does not stay the process tool of grinding theeth allowance.Existing pre-grinding hob secondary clamping can lose precision.
Summary of the invention
The utility model provides pre-grinding hob, and the utility model solves the problem that existing pre-grinding hob secondary clamping can lose precision.
For solving the problem, the utility model adopts following technical scheme: pre-grinding hob, comprises hobboing cutter cutter head and knife bar; There is micro-cone mandrel knife bar front end, micro-cone mandrel and knife bar integrative-structure, and micro-cone mandrel front end is the small end of taper; Have micro-taper hole in hobboing cutter cutter head, hobboing cutter cutter head is installed on micro-cone mandrel, and micro-taper hole coordinates with micro-cone mandrel, and the tapering of micro-taper hole and micro-cone mandrel is 1:85-90.
The utility model applies micro-cone mandrel clamping, and cutter inspection and secondary clamping can not lose precision.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Symbol description in figure: hobboing cutter cutter head 1, knife bar 2, micro-cone mandrel 3.
Detailed description of the invention
By best embodiment, the utility model is described in detail below
.
As shown in Figure 1, pre-grinding hob, comprises hobboing cutter cutter head 1 and knife bar 2; There is micro-cone mandrel 3 knife bar 2 front end, micro-cone mandrel 3 and knife bar 2 integrative-structure, and micro-cone mandrel 3 front end is the small end of taper; Micro-taper hole is had in hobboing cutter cutter head 1, hobboing cutter cutter head 1 is installed on micro-cone mandrel 3, micro-taper hole coordinates with micro-cone mandrel 3, the tapering of micro-taper hole and micro-cone mandrel 3 is 1:85-90, this parameter is that inventor goes out through a large amount of experimental summaries, adopts this tapering can improve the precision of pre-grinding hob greatly.After hobboing cutter cutter head 1 and micro-cone mandrel 3 assemble, hobboing cutter cutter head 1 front end face is 5-10 millimeter to micro-cone mandrel 3 end end distance.There is external screw thread in micro-cone mandrel 3 front end, external screw thread is combined with nut by hobboing cutter cutter head 1 fixation.
Pre-grinding hob precision of the present utility model is cutter AAA level, and on processing market at home, other products does not almost reach the requirement of precision.For the manual programming software of import five-shaft numerical control grinding machine and open lathe, carry out processing and manufacturing, apply micro-cone mandrel clamping, inspection and secondary clamping can not lose precision.
Production technology: (1) programmes according to the profile of tooth of each tooth.(2) pinion cutter special inspecting equipment detects.Application numerical control five-axle cutter and tool grinding machine mill rib ensures the precision of AAA level pre-grinding hob, and micro-cone mandrel ensures the positioning precision of clamping and repeated clamping.
Last it is noted that obviously, above-described embodiment is only for the utility model example is clearly described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of amplifying out or variation be still among protection domain of the present utility model.
Claims (2)
1. pre-grinding hob, comprises hobboing cutter cutter head and knife bar; It is characterized in that, there is micro-cone mandrel knife bar front end, micro-cone mandrel and knife bar integrative-structure, and micro-cone mandrel front end is the small end of taper; Have micro-taper hole in hobboing cutter cutter head, hobboing cutter cutter head is installed on micro-cone mandrel, and micro-taper hole coordinates with micro-cone mandrel, and the tapering of micro-taper hole and micro-cone mandrel is 1:85-90.
2. pre-grinding hob as claimed in claim 1, is characterized in that, after hobboing cutter cutter head and micro-cone mandrel assemble, hobboing cutter cutter head front end face is 5-10 millimeter to Wei Zhui core shaft end end distance.
