Description
Technical field
This utility model relates to mechanized equipment technical field, is specifically related to a kind of hobcutter based on vertical gear hobber and installs
Device.
Background technology
Gear hobbing lathe is arranged by its structure can be divided into horizontal and vertical two big classes, it is however generally that, vertical gear hobber is due to work
Part gravity direction is the support of support, and therefore its stress is suitable for well processing the large-scale and gear hobbing process of heavy-duty gear and precision
Require the gear hobbing process of higher gear.
Although the Chinese invention patent of Publication No. CN103406601A discloses a kind of vertical five axle rolling
Tooth machining tool, including frame, hob head is located in frame by column, and hob head is provided with hobboing cutter, and the first servomotor is even
Connecing hobboing cutter, the second servomotor connects column；Workbench is located in frame by bracket, be used for driving workpiece to be processed tooth base around
The 3rd servomotor rotated from axle is located on workbench, the 4th servomotor connecting working table, and the 5th servomotor connects torr
Frame；Workpiece to be processed tooth base axis and workbench horizontal plane.The motion of the most each moving component is all by different
Driven by servomotor, but owing to it is disclosed that a kind of principle or conception, how to arrange between concrete all parts and connect
The relation of connecing is not elaborated, and how to install such as hobcutter and not only can guarantee that installation accuracy but also be convenient for changing, and still has the space continuing research and development.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of hobcutter based on vertical gear hobber is pacified
Assembling device, taked technical scheme be:
A kind of hobcutter erecting device based on vertical gear hobber, including relay axis assembly, alters cutter splined shaft, and its feature exists
In: described relay axis assembly includes that the spline housing being installed on gear hobbing rotary table, spline housing and the epimere altering cutter splined shaft are joined
Closing, the centre bore of the hypomere and hobcutter of altering cutter splined shaft arranges flat key keyway and is connected fixing, alters cutter splined shaft and arranges centre bore,
Centre bore is inserted into T-shaped pull bar, sheathed some disc springs on the pull bar between drawhead and the upper end altering cutter splined shaft；Pull bar
Upper surface abuts with the lower surface of disc spring push rod, and disc spring push rod connects the piston rod of gear hobbing cutter drawing cylinder；The upper end of pull bar
Face coordinates cutter snap component.
Further, described cutter snap component engages with pull bar, when cutter snap component rotates 90 ° relative to pull bar
Time, cutter snap component departs from pull bar.
Compared with prior art, hobcutter erecting device structure of the present utility model is ingenious, simplifies change gear system, coordinates
Relation is reasonable, can make cutter shaft part lightweight, reduces overall weight, improves and adjusts convenience；Break traditions nut check
Mode, uses hydraulic pressure strain mode, both ensures to lock rigidity, ensures to alter the smoothness of cutter again, it is ensured that hobboing cutter kinetic energy
The stability of transmission and rigid requirements, thus ensure that there is relatively high control precision, and the serrated knife more renewed also become very
Convenient.
Accompanying drawing explanation
Fig. 1 is the vertical gear hobber structural representation at this utility model and place.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, as shown in the figure:
A kind of hobcutter erecting device based on vertical gear hobber, including relay axis assembly 7, alters cutter splined shaft 6, its feature
Be: described relay axis assembly 7 includes the spline housing being installed on gear hobbing rotary table 3, spline housing with alter the upper of cutter splined shaft 6
Duan Peihe, the hypomere splined hole centrally disposed with hobcutter 4 altering cutter splined shaft 6 coordinates flat key keyway to be connected, alters cutter splined shaft 6 and set
Putting centre bore, centre bore is inserted into T-shaped pull bar 15, if sheathed on the pull bar between drawhead and the upper end altering cutter splined shaft 6
Dry disc spring 17；The upper surface of pull bar 15 abuts with the lower surface of disc spring push rod 14, and disc spring push rod 14 connects gear hobbing cutter tension oil
The piston rod of cylinder 9；The upper surface of pull bar 15 coordinates cutter snap component 16.Described cutter snap component 16 is blocked with pull bar 15
Closing, when cutter snap component rotates 90 ° relative to pull bar 15, cutter snap component 16 departs from pull bar 15.
When needing to change hobcutter, need hobboing cutter slide unit 5 to rise to extreme higher position and by hydraulic automatic locking device 2
Locking, then gear hobbing cutter drawing cylinder 9 drives disc spring push rod 14 to push down on, and disc spring push rod 14 compresses disc spring 17, with disc spring phase
Pull bar 15 even and cutter snap component 16 with matching are unclamped, and after rotating 90 °, snap component 16 gets final product Automatic-falling, so
After more renew gear hobbing cutter, treat that cutter installs, cutter snap component 16 turned round 90 °, do not allow its self falling, unclamp rolling
Serrated knife tool drawing cylinder 9, completes cutter changing work.
