Under the condition that the structure of the machine tool need not be changed, the utility model can carry out the processing of a straight teeth column gear, a worm wheel, and a spline rolling gear with a minor diameter; the utility model has the advantages of high productive efficiency, high processing accuracy ratio, simple structure, and convenient operation, which is suitable for the teeth part processing of middle-size or small-size factories and farm implement repairing factories of machines with special purposes such as machines without rolling gears.
Description
The utility model belongs to the lathe metal-cutting machine tool.
The lathe that adopts generating process to add work gear has gear-hobbing machine etc., the production efficiency height, and the accuracy of gear grade height after the processing, but because the gear-hobbing machine price is expensive, therefore many factories do not possess this kind equipment.Adopt forming process to add work gear and can utilize forming tool and indexing means on plain-milling machine, planer, to carry out, easy to process, but production efficiency is low, and processing accuracy of gear grade is low.
The purpose of this utility model is to be higher than forming process for the medium or small factory that does not possess gear-hobbing machine provides a kind of production efficiency height that uses, machining accuracy grade on engine lathe, gear hobbing instrument simple in structure, be widely used in straight spur gear, the gear hobbing processing of worm gear and minor diameter spline.
The utility model is achieved in that including hob arbor carriage, workbench, worm reducer, intermediate gearing and support forms (seeing Fig. 1, Fig. 2).Formed hob arbor carriage by the gear drive between tool holder casing (10), power shaft (2) and hobboing cutter main shaft (8) and the diaxon.Power shaft (2) coaxial line vertical with hobboing cutter main shaft (8) is fastened on the front end head of lathe spindle (1), the knife bar (25) of packing in the hobboing cutter main shaft (8), cogged hobboing cutter (24) on the knife bar, rotatablely moving of lathe spindle (1) given hobboing cutter main shaft (8) by power shaft (2) and gear transmission, makes the main motion in the motion of gear hob (24) realization rolling cut.Power shaft (2) is by bearing (20) supporting tool holder casing (10), housing (10) is finished the adjustment of hobboing cutter established angle with hobboing cutter main shaft (8) and gear hob (24) around axis tilt one angle of power shaft (2), after the adjustment tool holder casing (10) is fastened on the support (22) that tightens together with lathe bed and goes up transfixion.Be fastened on to be equipped with the work spindle (35) and the bearing (34) of lathe spindle axis normal in the workbench housing (11) on the horizontal slide carriage of lathe (38) with screw and formed workbench, work spindle (35) is to reach by adjusting the angle position of workbench housing (11) in horizontal plane with the perpendicularity of lathe spindle (1) axis.The front end of work spindle (35) is equipped with work arbor (36) and processed tooth base (37), and afterbody can axially slippage in worm gear (12) keyhole of worm reducer.Worm reducer is made up of worm gear (12) and worm screw (14), and worm reducer is fastened on the vertical slide carriage (29) with work spindle (35) location and by support (26), (27).Intermediate gearing is made up of garden bevel gear pair (15), (16) and (30), (31), (or helical tooth wheel set or change gear) and power transmission shaft (17), gear (15) (30) respectively with outer feed rod (32) key connecting of worm shaft (14) and lathe slip crate.The outer feed rod (32) of lathe slip crate connects transmission by intermediate gearing with worm shaft (14), has been made up of the interior contact driving-chain of hobboing cutter main shaft (8) to work spindle (35).Change gear and basic gear by changing lathe feed rod feed system and increase times mechanism and can satisfy hobboing cutter main axis rotation 1 and change the requirement (K: hobboing cutter head number that work spindle rotation K/Z changes; Z: the processed gear number of teeth).Formed the gear hobbing generating motion driving-chain of hobboing cutter main shaft (8) to work spindle (35).
Axial feed motion in the gear hobbing is to advance the transverse movement that leading screw and screw drive the horizontal slide carriage of lathe (38) and realize by lathe is horizontal.Rotatablely moving of infeed leading screw is to utilize motor-driven handle of lathe infeed or infeed manual handle to realize.
The adjustment of gear hobbing penetraction depth is to move vertical slide carriage (29) and reach by rotating big handwheel.
Removable vertical slide carriage (29) adopts the radial feed machining worm wheel when work arbor (36) is gone up dress worm gear blank.
Utilize the instrument small diameter shaft of packing in the axis hole of work spindle (35), going up the dress spling hob at knife bar (25) can be at small diameter shaft overhanging end rolling cut spline.
The utility model has the advantages that and under the prerequisite that does not change machine tool structure on the maximum engine lathe of quantity, to utilize the utility model to carry out straight spur gear, the gear hobbing processing of worm gear and minor diameter spline.The utility model is simple in structure, and low cost of manufacture is easy to use, and is easy to maintenance, the production efficiency height, and the machining accuracy grade is applicable to the medium or small factory that does not possess special purpose machine tools such as gear-hobbing machine than forming process height, the tooth portion processing of farm build factory.
