Background technology
For the precision gear part that needs carry out thick, smart twice gear hobbing processing, the centering centering of hobboing cutter GD and workpiece G is extremely important during fine finishining, because it has influence on uniformity coefficient, the tooth accuracy of allowance.The centering aligning method that adopts is to adjust lathe by pure manual type now, with the cutter tooth of hobboing cutter to the middle part to the workpiece gear teeth, and the centering of hobboing cutter is mainly by the artificial visually examine, the error of centralization is bigger, the profile of tooth center that processes is inaccurate, the asymmetric phenomenon in the flank profil left and right sides occurs easilier during especially for the less gear of the processing rolling cut number of teeth, and then cause profile of tooth to change, influence machining accuracy.
In addition, in the centering operating process, need to adjust the hobboing cutter centre-to-centre spacing position of lathe and the circumferential position of workpiece, often occur the phenomenon that the workpiece flank of tooth is scratched, hobboing cutter damages at present, be badly in need of solving the problems of the technologies described above for this reason.
The utility model content
Technical problem to be solved in the utility model be to provide a kind of for gear-hobbing machine to cutter mechanism, to realize hobboing cutter and workpiece centering centering accurately and quickly.
The technical solution of the utility model is as follows: a kind of for gear-hobbing machine to cutter mechanism, it is characterized in that: comprise cutter mechanism mount pad (1) and trunnion axis (2), wherein the left part of trunnion axis (2) is with fixing to cutter mechanism mount pad (1), and the upper end of the right part of this trunnion axis (2) and link (3) is fixed; Be equipped with cutter shaft (4) in the installing hole of described link (3) bottom, to cutter shaft (4) and this installing hole matched in clearance, and parallel with described trunnion axis (2) to cutter shaft (4), and be positioned at trunnion axis (2) under;
Described left part to cutter shaft (4) is tool setting conus portion (4a), and its right part has V-arrangement tool setting groove (4b) along axial line, and the angle of this V-arrangement tool setting groove (4b) equates with the tapering of described tool setting conus portion (4a).
During installation, by cutter mechanism mount pad (1) is installed and fixed this to cutter mechanism and knife rest (DJ), and to the tool setting conus portion (4a) of cutter shaft (4) teeth groove over against hobboing cutter (GD).
During tool setting, the V-type groove (4b) of cutter shaft (4) is stuck in the both sides of gear (being workpiece G) flank profil, the tool setting conus portion (4a) of cutter shaft (4) inserts in the teeth groove of hobboing cutter (GD), contact area size by contrast V-type groove (4b) two sides judges whether to finish tool setting, in order to guarantee the relative gear centre axial symmetry in the flank profil left and right sides that fine finishining is come out.After finishing tool setting, this is pulled down cutter mechanism, in order to carry out gear hobbing processing.
Adopt above technical scheme, this can realize hobboing cutter and workpiece centering centering accurately and quickly to cutter mechanism, both has been not easy to scratch the workpiece flank of tooth, be not easy to damage hobboing cutter again, simple in structure, easy to implement, overcome the defective of prior art well, be suitable for extensively promoting the use.
As preferably, the left part of described trunnion axis (2) inserts in the installing hole on the cutter mechanism mount pad (1), this insertion section locks the milled screw (5) on the cutter mechanism mount pad (1) by being located in, and the bar portion of milled screw (5) is vertical with trunnion axis (2).
Adopt above structure, after finishing tool setting, only need unclamp milled screw (5) and just can cutter mechanism mount pad (1) then be fixedlyed connected with knife rest (DJ) all the time except to the cutter mechanism remaining part is pulled down the cutter mechanism mount pad (1), convenient to disassembly.
As optimization, the right part of described trunnion axis (2) inserts in the connecting hole on link (4) top, and this insertion section is by holding screw (6) tightening, and holding screw (6) is vertical with trunnion axis (2).
In the utility model, described right part to cutter shaft (4) is the flat horizontal surface section, and described V-arrangement tool setting groove (4b) is opened on this flat horizontal surface section, and the gradient of V-arrangement tool setting groove (4b) cell wall is 20 °.
Beneficial effect: this can realize hobboing cutter and workpiece centering centering accurately and quickly to cutter mechanism, both has been not easy to scratch the workpiece flank of tooth, is not easy to damage hobboing cutter again, and is simple in structure, easy to implement, has overcome the defective of prior art well, is suitable for extensively promoting the use.
