Description
Technical field
The present invention relates to gear-hobbing machine lathe, especially relate to a kind of expanding unit of gear-hobbing machine lathe.
Background technology
At present, the manufacturing capacity of gear wheel in large diameter, limit the development of China's Gear Industry always, also limit manufacturing and designing of big machinery drive apparatus simultaneously, the gear-hobbing machine of existing domestic sizing producer is generally only produced to 5 meters, having a little bigger is once in a while also only about 8 meters, belongs to non-typical specific products.Secondly the gear-hobbing machine of general manufacturer production all belongs to plain edition lathe, and bearing capacity is little, and precision is not high yet, cannot meet the process requirements of weight, large enterprise, does not have within 1 year, to be definitely cannot give to use business from delivery cycle.In the tediously long Machine Manufacture cycle, the manufacturing cost of high cost, is all unfavorable for user.
Summary of the invention
The present invention is the deficiency solved the problems of the technologies described above, and provides a kind of expanding unit of gear-hobbing machine lathe, solves the problem that small-sized gear-hobbing machine machine tooling scope is too small, saves cost, instant effect.
The technical scheme that the present invention adopts for the deficiency solved the problems of the technologies described above is:
A kind of expanding unit of gear-hobbing machine lathe, be provided with end supporting seat, end supporting seat is supported main workbench by table base, table base side connecting machine tool lathe bed, bed piece is provided with main guide rail, main guide rail is provided with column and main spindle box, table base is provided with rotary drive mechanism, drive main worktable rotary, auxiliary table is provided with above main workbench, auxiliary table is by least three Elastic supporting roller unit supports, and bed piece is also provided with accessory rail, and accessory rail is connected with main guide rail;
Described Elastic supporting roller unit comprises carrying roller roller, brace, hydraulic jack and bracing frame, bracing frame and hydraulic jack is vertical side by side arranges, brace is horizontally disposed with, its one end and bracing frame hinged, its other end is supported by the piston rod of hydraulic jack, and brace is provided with carrying roller roller.
The diameter of auxiliary table of the present invention is greater than the diameter of main workbench.
The invention has the beneficial effects as follows:
1, just the range of work will changing a social system lathe can effectively be strengthened, small investment, instant effect by cutter expanded range, supporting surface expansion and supplemental support.
2, through carrying out relevant transformation to this similar structure machine tool, equally all can under small investment, cycle short condition the effective overall processing scope improving lathe.And transformation is the former machining accuracy that peripheral hardware annex does not affect lathe self.Select add and remove equal convenient, versatility is extremely strong.

Detailed description of the invention
As shown in the figure, a kind of expanding unit of gear-hobbing machine lathe, be provided with end supporting seat 8, end supporting seat 8 is supported main workbench 6 by main table base 7, table base 7 side connecting machine tool lathe bed 10, bed piece 10 is provided with main guide rail 14, main guide rail 14 is provided with column 11 and main spindle box 12, table base 7 is provided with rotary drive mechanism 5, rotary drive mechanism 5 drives main workbench 6 to rotate, auxiliary table 3 is provided with above main workbench 6, auxiliary table 3 is supported by least three Elastic supporting roller unit 4, bed piece 10 is also provided with accessory rail 13, accessory rail 13 is connected with main guide rail 14,
Described Elastic supporting roller unit 4 comprises that carrying roller roller 401, brace 402, hydraulic jack 403 and bracing frame 404, bracing frame 404 and hydraulic jack 403 are vertical side by side to be arranged, brace 402 is horizontally disposed with, brace 402 one end and bracing frame 404 hinged, the other end is supported by the piston rod of hydraulic jack 403, and brace 402 is provided with carrying roller roller 401.
The diameter of auxiliary table 3 of the present invention is greater than the diameter of main workbench 6.The basis not changing original machine tool structure expands the lathe range of work, expands the Area of bearing of gear hobbing machine worktable, save cost.Utilize existing junior machine, just can effectively strengthen its range of work, small investment, instant effect by cutter expanded range, supporting surface expansion and supplemental support.
Gear-hobbing machine tool sharpening expanded range is the extending design for lathe itself.The range of work of space enlargement cutter is moved after extending column.The minimum process scope retaining former lathe is constant, effectively can change again the scope of processing.
Embodiment 1
According to effective travel and the 8 rice diameter requirements requiring workpiece of lathe, calculate and design and produce a set of back work guide rail and driven accessary axial workpiece length 1.3 meters, increase corresponding rigidity spline linking sleeve and bracket.Object moves the range of work of space enlargement cutter after extending column.The minimum process scope that can retain former lathe is like this constant, effectively can change again the scope of processing.The bearing strength impact of the length increased on axial workpiece is little, and practice shows that parts depreciation degree is all not high so far after transformation.
Expand the Area of bearing of workbench, an additional large diameter back work table top, the increase of diameter ring gear, certainly will cause the fact of the strong point distance increasing workbench.There is employing " umbrella shape " rod-pulling type device in the past, had the bracing or strutting arrangement of " support muscle formula ".These types are only applicable to the ring gear machining of super workbench increase diameter among a small circle, just must adopt back work table top, so just can effectively reach firm support for processing on a large scale to change.
Auxiliary table is coordinated to make effective supplemental support carrying roller.The increase of tall auxiliary mesa, certainly the bearing capacity of rotary table will be increased accordingly, the flexibility characteristics of hydraulic system is utilized to manufacture and design hydraulic pressure auxiliary wheel device, the good contact condition improving roller and auxiliary table guide pass, allow the collision of rigidity change the flexibility with certain support force into lift, address this problem thoroughly.In hydraulic cylinder, the height of the reciprocating motion adjustment carrying roller roller of piston is to adapt to auxiliary table height change, is protected and set corresponding force value to meet the requirement of support force on the strong point by hydraulic valve.The hydraulic valve releasing pressure automatically when pressure exceeds setting value, ensures that the normal safe of system runs.According to the weight of workpiece, according to lathe peripheral environment, the carrying roller element number needed for setting, calculates the ratio that auxiliary shoring system participates in off-load, determines the setting pressure of hydraulic roller wheel.A set of Elastic supporting roller mechanism is set.
