Vertical four-shaft numerically controlled gear shaving machine machine arrangement
Technical field
The utility model belongs to numerical control gear shaving machine manufacturing technology field, particularly a kind of vertical four-shaft numerically controlled gear shaving machine machine arrangement.
Background technology
Shaving technology normally to gear at the preceding a kind of method for fine finishing of heat treatment (gear hardens).That is to say must stay before shaving and shave surplus, is not directly to shave involute gear on the tooth base, so gear shaving machine is the finishing machine that belongs to gear.But general shave external toothing straight spur gear and helical gears; And shave barreled tooth flank and conelet degree tooth etc., also can carry out shave processing at present to the gear of middle hard gear-face.The plain edition gear shaving machine has only a kind of function of axial shaving, and its table stroke length is long, and production efficiency is low.
Summary of the invention
The utility model provides a kind of compact conformation for solving the technical problem that exists in the known technology, operates steadily, machining accuracy height, workable vertical four-shaft numerically controlled gear shaving machine machine arrangement.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of vertical four-shaft numerically controlled gear shaving machine machine arrangement mainly comprises lathe bed, workbench, column and the knife rest that gear shaver is installed; It is characterized in that: the pair of parallel guide rail is installed on lathe bed, be furnished with supporting plate on the guide rail, column is installed on the supporting plate, one end of column connects the ball-screw that the pulling column moves horizontally along X-axis, ball-screw is installed on the lathe bed, ball-screw connects drive motors, slide plate is installed on the column, knife rest is installed on the slide plate, gear shaver is installed on the knife rest, be vertically installed with on the column and drive the ball-screw that knife rest moves up and down along Y-axis, the rear side of described column upper slide is equipped with and drives knife rest rotate respective angles on slide plate worm gear, torque motor and the rotating turntable bearing of support table that the drive workbench rotates is installed below the described workbench.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, ball-screw drives column and realizes moving horizontally of column; Ball-screw drives slide plate and realizes that the vertical of knife rest moves; Worm gear drives the knife rest revolution and realizes the adjustment campaign at knife rest angle of inclination, and promptly knife rest is around the gyration of the knife rest centre of gyration; The gyration of workbench is adopted torque motor driving, work table rotation to support and is adopted the turntable bearing.This layout has compact conformation, and motion is steady, the machining accuracy height; Whole process needs the manually adjustment except that workpiece clamps, and other is controlled by digital control system, and is workable, the working (machining) efficiency height.

Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, lathe bed; 2, workbench; 3, column; 4, gear shaver; 5, knife rest; 6, guide rail; 7, supporting plate; 8, ball-screw; 9, slide plate; 10, ball-screw.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, a kind of vertical four-shaft numerically controlled gear shaving machine machine arrangement mainly comprises lathe bed 1, workbench 2, column 3 and the knife rest 5 that gear shaver 4 is installed; Pair of parallel guide rail 6 is installed on lathe bed 1, be furnished with supporting plate 7 on the guide rail 6, column 3 is installed on the supporting plate 7, one end of column 3 connects the ball-screw 8 that the pulling column moves horizontally along X-axis, ball-screw 8 is installed on the lathe bed 1, ball-screw 8 connects drive motors, slide plate 9 is installed on the column 3, knife rest 5 is installed on the slide plate 9, gear shaver 4 is installed on the knife rest 5, be vertically installed with on the column 3 and drive the ball-screw 10 that knife rest moves up and down along Y-axis, the rear side of described column upper slide 9 is equipped with the worm gear (indicating among the figure) that drives knife rest and rotate respective angles on slide plate, is equipped with below the described workbench 2 to drive torque motor that workbench rotates and the rotating turntable bearing of support table (among the figure sign).
Operation principle: ball-screw 8 drives column 3 and realizes moving horizontally of column; Ball-screw 10 drives slide plate 9 and realizes that the vertical of knife rest 5 moves; Worm gear drives the knife rest revolution and realizes the adjustment campaign at knife rest angle of inclination, and promptly knife rest is around the gyration of the knife rest centre of gyration; The gyration of workbench 2 is adopted torque motor driving, work table rotation to support and is adopted the turntable bearing.This layout has compact conformation, and motion is steady, the machining accuracy height; Whole process needs the manually adjustment except that workpiece clamps, and other is controlled by digital control system, and is workable, the working (machining) efficiency height.
See also Fig. 1, before the processing, workpiece is installed on the workbench 2, adjust the center of workpiece, make itself and workbench 2 concentric, lock-screw; Gear shaver 4 is installed on the knife rest 5, adjust the control program in the digital control system, driven by motor ball-screw 8 and ball-screw 10 motions, make column 3 along X-axis, slide plate 9 drives knife rest 5 and moves along Y-axis, gear shaver 4 is contacted with workpiece, worm gear behind the motor-driven slide plate 9, make knife rest 5 rotate corresponding angle on slide plate 9, making does not have gap (two-sided) engagement between gear shaver 4 and the workpiece, and the torque motor below the workbench drives workbench 2 and drives workpiece and be rotated, because the meshing point velocity attitude of workpiece and gear shaver 4 is opposite, therefore, produce relatively on the flank of tooth and slide, this lathe is finished machining according to this principle.
