The utility model is numerical control gear rolling machine cutter shaft clamping device, has radial support effect to cutter shaft.The utility model comprises numerical control gear rolling machine column, is fixed on the lower clamp knife body of numerical control gear rolling machine column lower end, and the upper end of lower clamp knife body is provided with hollow lower clamp knife body main shaft, and lower clamp knife body main shaft is arranged on lower clamp knife body by bearing; The endoporus of lower clamp knife body main shaft is furnished with elastic expansion-sleeve, and the tapering of the endoporus of lower clamp knife body main shaft is identical with the tapering of elastic expansion-sleeve external diameter, and upward, the axial line of elastic expansion-sleeve overlaps with the cutter shaft axial line of numerical control gear rolling machine the large end of cone mouth; The lower end of elastic expansion-sleeve is fastened with connecting rod, and the other end of connecting rod is arranged on by bearing and connects on pole socket, and connect the lower end of pole socket and be connected with the piston rod of hydraulic cylinder, hydraulic cylinder is arranged on lower clamp knife body.The utility model greatly reduces cutter shaft flexural deformation, enhances cutter shaft rigidity and extends service life, and the machining accuracy of lathe and the quality of product have also been obtained guarantee.
Description
Technical field
The utility model is to numerical control gear rolling machine cutter shaft lower end automatic clamping device, has radial support effect to cutter shaft.
Background technology
The cutter shaft of numerical control gear rolling machine is originally that only upper end is fixed on machine tool chief axis, lower end is then without any support, when converted products because squeeze force is large, easily cause the cutter shaft flexural deformation of cantilever, after cutter shaft flexural deformation, the machining accuracy of lathe is greatly affected, the quality of product can not be guaranteed, and cutter shaft also needs frequent replacing.
Utility model content
The utility model object is to provide a kind of numerical control gear rolling machine cutter shaft clamping device.
The technical solution of the utility model: a kind of numerical control gear rolling machine cutter shaft clamping device, comprise numerical control gear rolling machine column, be fixed on the lower clamp knife body of numerical control gear rolling machine column lower end, the upper end of lower clamp knife body is provided with hollow lower clamp knife body main shaft, and lower clamp knife body main shaft is arranged on lower clamp knife body by bearing; The endoporus of lower clamp knife body main shaft is furnished with elastic expansion-sleeve, and the tapering of the endoporus of lower clamp knife body main shaft is identical with the tapering of elastic expansion-sleeve external diameter, and upward, the axial line of elastic expansion-sleeve overlaps with the cutter shaft axial line of numerical control gear rolling machine the large end of cone mouth; The lower end of elastic expansion-sleeve is fastened with connecting rod, and the other end of connecting rod is arranged on by bearing and connects on pole socket, and connect the lower end of pole socket and be connected with the piston rod of hydraulic cylinder, hydraulic cylinder is arranged on lower clamp knife body.
Lower clamp knife body main shaft is arranged on lower clamp knife body by a pair taper roll bearing.
The lower end of connecting rod is arranged on by deep groove ball bearing and connects on pole socket.
The utility model achieves numerical control gear rolling machine cutter shaft Automatic-clamping, Bidirectional supporting.Greatly reduce cutter shaft flexural deformation, enhance cutter shaft rigidity and extend service life, the machining accuracy of lathe and the quality of product have also been obtained guarantee.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the schematic diagram that the utility model is installed on numerical control gear rolling machine.
In figure: 1 slide unit servomotor, about 2 slide units, 3 rotary main shafts, 4 cutter shafts, 5 lower clamp knife bodies, 6 line slideways, 7 column servomotors, 8 ball-screws, 9 numerical control gear rolling machine columns, 10 elastic expansion-sleeves, 11 lower clamp knife body main shafts, 12 taper roll bearings, 13 connecting rods, 14 connect pole socket, 15 hydraulic cylinders.
Detailed description of the invention
As shown in drawings, the utility model is arranged on the lower end of numerical control gear rolling machine column, and primarily of elastic expansion-sleeve, lower clamp knife body main shaft, taper roll bearing, connecting rod, connects pole socket, the compositions such as hydraulic cylinder.
For ensureing that moving component is steadily reliable, main components casting forms.Other critical piece is durable for ensureing, all through heat treatment.
Upper and lower slide unit is connected with numerical control gear rolling machine column by line slideway, column servomotor connects upper and lower slide unit by ball-screw, controls upper and lower slide unit and moves, and slide unit servomotor connects rotary main shaft, rotary main shaft is connected with upper and lower slide unit by bearings, guarantees rotary main shaft running accuracy.Cutter shaft upper end is fixedly mounted on rotary main shaft, lower clamp knife body is fixedly mounted on numerical control gear rolling machine column lower end, lower clamp knife body main shaft is supported by taper roll bearing and is connected with lower clamp knife body, hydraulic cylinder is connected with elastic expansion-sleeve (prior art) by connection pole socket and connecting rod (connect between pole socket and connecting rod and deep groove ball bearing is housed), move up and down by hydraulic cylinder piston the tensioner that controls elastic expansion-sleeve and unclamp, thus reaching clamping or unclamp the object of cutter shaft lower end.
Before work, first up and down slide unit moves downward, cutter shaft lower end enters elastic expansion-sleeve, behind in-position, hydraulic cylinder pulls down dynamic elasticity ringfeder clamping cutter shaft lower end, and then lathe is started working in converted products, after machining, hydraulic cylinder upwardly elastic expansion-sleeve unclamps cutter shaft lower end, and upper and lower slide unit moves upward, and band movable arbor gets back to starting position.
