Abstract

The utility model relates to an adjustable inclined type universal machine for edge-grinding and chamfering gears, which belongs to the technical field of gear auxiliary processing and machine manufacture. The utility model is characterized in that one side of the bottom of a main shaft box is hinged with a machine tool face, and the other side is connected with the machine tool face through an adjusting device; a motor and change gears are positioned on the main shaft box; two sets of grinding wheels are driven by an air-driven grinding machine, and the two sets of grinding wheels are respectively positioned on vertical columns at both sides of the main shaft box by a supporting frame and a rotating shaft; the vertical columns are respectively positioned on two saddle seats which are positioned on the machine tool face. The utility model has the advantages that the utility model can be used for manufacturing a shaft gear with the root circle similar to the shaft diameter, can be used for chamfering a shaft gear with a stepped disk, and can be used for chamfering bevel gears with various angles; besides, the utility model integrates a vertical machine and a horizontal machine into integration, and is convenient and practical.

Description

Machine for finishing gear teeth

The mill rib chamfering that the utility model is mainly used in gear adds, and belongs to a kind of gear secondary process mechanical manufacturing field.

Background technology of the present utility model is: in the existing machinery manufacturing, chamfering along the profile of tooth two ends in the Gear Processing process is mainly contained two kinds of forms: one for chamfering before the heat, promptly carries out chamfering with dedicated tool and special purpose machine tool in the mode of machining before the heat place.This mode is used commonplace, but can not advance chamfering to the hard attitude profile of tooth after the heat treatment, and structure and operate all more complicated, and production efficiency is low, and processing cost is than higher; Two is heat back chamfering, promptly carries out chamfering in the mode with grinding after the heat treatment on the hard flank of tooth.Mainly contain vertical and horizontal edge-grinder.A kind of deficiency of mode also can be advanced chamfering to hot front gear before this equipment had solved, and structure and operation are also fairly simple.But can not carry out chamfering to the more approaching band platform plate-like gear of the more approaching shaft gear in various bevel gears and the diameter of axle and tooth root garden and tooth root garden and stepped diameters.And vertical, horizontal its limitation arranged respectively separately.

Purpose of design of the present utility model is to provide a kind of new gear mill rib chamfering machinery, what solve the existence of existing vertical and horizontal gear mill rib beveler can not be to the problem of the more approaching band platform plate-like gear chamfering of the more approaching shaft gear in various bevel gears and the diameter of axle and tooth root garden and tooth root garden and stepped diameters, and with vertical and horizontal two kinds of edge-grinder unity of form, the repertoire and the advantage that have vertical and horizontal two kinds of forms simultaneously, not only range of application is wider, and more convenient and practical.

Design of the present utility model is: at the problem and shortage of existing gear chamfering equipment existence, the main shaft of designing a kind of novelty becomes the gear mill rib chamfering equipment of incline structure, its organization plan is: the omnipotent gear mill of a kind of adjustable tilting rib beveler, it comprises lathe bed surface (1), one side of main spindle box (2) bottom is hinged by bearing pin syndeton and lathe bed surface (1), opposite side is connected with lathe bed surface (1) by adjusting device (7), motor (6) and change gear are positioned on the main spindle box (2), the driven by motor change gear, change gear is connected with scroll bar, scroll bar drives turbine, turbine drives main shaft (5), emery wheel (4) is on two groups of columns that driven and lay respectively at by support and rotating shaft main spindle box (2) both sides by air operated portable grinder and can does, following and left, the right adjustment, column lays respectively on two saddles and before can doing, the back is adjusted, and saddle is positioned on the lathe bed surface (1).α angle of main shaft (5) and horizontal lathe bed surface inclination, the α angle is 1 °--90 °.Adjusting device (7) is following outstanding screw structure, and its long surplus part can be hung within the bed piece.Motor (6) is the gear reduction motor.(Fig. 2--Fig. 4): (3) are workpiece to its operation principle among the figure, and (4) are emery wheel.Emery wheel also has the motion of upper and lower swing with the workpiece end face profile of tooth except that rotation.(2) are the duty of vertical machine among the figure, and the direction of its emery wheel swing is parallel with axis of workpiece.When the Gear Root garden is close with the diameter of axle, lathe can't be processed; Figure (3) is the duty of horizontal machine, and the direction of its emery wheel pendulum and axis of workpiece are at an angle of 90.When the Gear Root garden was close with the diameter of axle, the diameter of axle or the chamfering of will fraying fallen less than root; Figure (4) is the work shape of the utility model " the omnipotent gear mill of adjustable tilting rib beveler ".The direction of its emery wheel swing becomes a α angle with axis of workpiece, the α angle is 1 °--and 90 ° are adjustable.Therefore can not only process the workpiece that all vertical machines and horizontal machine can be processed, and can also process the tooth root garden gear and the various bevel gear close that they can not be processed, neither can hurt the diameter of axle, can also be worked into root with the diameter of axle.

The utility model is compared with background technology, and the one, can process tooth root garden that existing edge-grinder institute can not the process shaft gear close and be with the chamfering of step plate-like gear with the diameter of axle, solved this difficult problem; The 2nd, can process the chamfering of the bevel gear of the various angles that existing edge-grinder can not process, widened its range of work; The 3rd, vertical machine and horizontal machine are unified in all over the body, not only range of application is wider, and convenient being suitable for.Can use less investment, create economic benefit more.
