Description

A kind of workpiece box for gear grinding machines
Technical field
The utility model relates to a kind of workpiece box, especially relates to a kind of workpiece box for numerically controlled tooth grinding machine.
Background technology
Numerically controlled tooth grinding machine is the equipment that the gear after heat treatment is carried out grinding, wherein workpiece box is the vitals on gear grinding machines, the indexing accuracy of workpiece box main shaft and the running accuracy of workpiece box, directly affect the machining accuracy of workpiece, traditional workpiece box main shaft generally passes through the worm gear transmission by servomotor, and this main axle structure precision is low, poor rigidity.
Summary of the invention
It is high, easy to operate that problem to be solved in the utility model is to provide a kind of positioning accuracy, is used for the workpiece box of numerically controlled tooth grinding machine.
for solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of workpiece box for gear grinding machines, comprise base, turning set, worm gear, worm screw, workpiece box and work spindle, described base is the casing that a heart section is provided with hollow multidiameter, turning set is connected on hollow multidiameter by a turntable bearing, described worm gear and turning set are affixed, described worm gear and worm engaging are connected, worm screw and servomotor interlock, described workpiece box is fixed on the upper surface of turning set, described work spindle is arranged in workpiece box, work spindle and torque motor interlock.
Further, be provided with a dampened disk between the upper surface of described turning set and described base, be provided with oil pocket and piston in described dampened disk, described dampened disk and turning set coaxial line.
Further, the rotor of described torque motor is fixed on work spindle, and the stator of torque motor is fixed in described workpiece box.
Advantage and the good effect that the utlity model has are: adopt technique scheme, torque motor and work spindle are direct-connected, improved the rigidity of workpiece box, make the workpiece calibration more accurate, the design of dampened disk, reduce the gap of worm gear, made whole transmission process more steady, improved the running accuracy of workpiece box.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model A-A cutaway view in Fig. 1.
In figure:
1. base 2. turning set 3. turntable bearings
4. workpiece box 5. work spindle 6. worm gears
7. worm screw 8. dampened disk 9. pistons
10. torque motor 11. clamping cylinder 12. servomotors
The specific embodiment
Enumerating a specific embodiment below in conjunction with accompanying drawing is further elaborated the utility model.
As shown in Figure 1 and Figure 2, the present embodiment is to comprise base 1, turning set 2, worm gear 6, worm screw 7, workpiece box 4 and work spindle 5, base 1 is the casing that a heart section is provided with hollow multidiameter, turning set 2 is connected on hollow multidiameter by a turntable bearing 3, worm gear 6 is affixed with turning set 2, worm gear 6 is connected with worm screw 7 engagement fit, worm screw 7 and servomotor 12 interlocks, workpiece box 4 is fixed on the upper surface of turning set 2, work spindle 5 is arranged in workpiece box 4, work spindle 5 and torque motor 10 interlocks.
In the present embodiment, the rotor of torque motor 10 is fixed on work spindle 5, and the stator of torque motor 10 is fixed in described workpiece box 4.
In the present embodiment, be provided with a dampened disk 8 between the upper surface of turning set 2 and base 1, be provided with oil pocket and piston 9 in dampened disk 8, dampened disk 8 and turning set 2 coaxial lines, dampened disk 8 the smooth rotation that has guaranteed workpiece box 4 is set; When grinding work piece, workpiece box 4 is subject to the cutting force of emery wheel, cutting force passes to worm gear by base 1, worm gear can repeatedly be thrown off-be meshed--throws off, transmission is unstable, be dampened disk 8 fuel feeding by hydraulic system this moment, piston 9 upper surfaces in dampened disk 8 will compress turning set 2, turning set 2 rotates under the effect of a kind of frictional force (damping), because worm gear 6 and turning set 2 tighten together, worm gear 6 is subject to such frictional force equally, and the cutting force of emery wheel can be offset or reduce to frictional force, has guaranteed stationarity and the transmission accuracy of transmission mechanism.
In the present embodiment, be connected with clamping cylinder 11 on the right side of work spindle 5, be used for dismantling or the workpiece of clamping work pieces main shaft 5 left ends, operation principle is simple, is easy to realize.
In the present embodiment, horizontally rotating by servomotor 12 of workpiece box 4 realize, servomotor 12 is with encoder, can realize the control of position, speed, belongs to half-closed loop control.The torque motor rotor is connected with angular encoder, belongs to closed-loop control; Overcome the problem of step out of stepping motor; In addition, heating problem has been avoided by circulating water in the torque motor outside, has improved the running accuracy of indexing accuracy and the workpiece box of work spindle.
In the present embodiment, rotatablely moving of work spindle 5 drives by torque motor 10, and torque motor 10 has soft mechanical property, can stall; Can automatically reduce rotating speed when load torque increases, strengthen simultaneously the output torque.When being certain value, load torque changes just adjustable speed of motor terminal voltage; Have the advantages such as the slow-speed of revolution, high pulling torque, overload capacity are strong, response is fast, the characteristic linearity is good, torque fluctuations is little, can directly drive load and save under drive gear, thereby improved the running precision of system.
In the present embodiment, multidiameter and 2 employing turntable bearings 3 of turning set of base 1 heart section, turntable bearing 3 have advantages of compact conformation, high axially and radially bearing capacity, high dip rigidity and very high degree of precision.
In sum, the utlity model has that positioning accuracy is high, the advantage of good rigidly and stable performance.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., within all should still belonging to patent covering scope of the present utility model.
