Abstract
The utility model aims at providing a workpiece box for a finishing machine of a numerical control gear-broach machine. The workpiece box is used for realizing high-precision indexing and the key parts of the workpiece box are all standard parts. According to the technical scheme, the workpiece box for the finishing machine of the numerical control gear-broach machine comprises a spindle and is characterized by comprising a torque motor, a turntable bearing, a thrust ball bearing, an end cover, a spindle connecting sleeve, a grating ruler, a workpiece box body, a box body rear cover and a workpiece clamping cylinder, wherein the torque motor comprises a stator and a rotor which is connected with the spindle through a bolt. The workpiece box has the beneficial effects that the spindle is controlled by the torque motor and is kept still in a gear-cutting project due to the structure; when a workpiece is indexed, the gapless transmission and high-precision indexing are realized as the torque motor is directly connected; and in the whole workpiece box, all the key parts are standard parts, thereby bringing convenience to the later exchanging and maintaining.
Description
Technical field
The utility model belongs to lathe and makes the field, relates in particular to a kind of workpiece box of numerical control gear-broach machine finishing machine.
Background technology
In the prior art, as shown in Figure 3 in whole machine tooling process, when needs main shaft 4 rotates; By digital control system control, make servomotor 6 energisings, by its transmission through gear wheel 2 and pinion 1, gear wheel 2 is connected with main shaft 4 usefulness screws; Rotate thereby drive main shaft 4, in the engineering of cutting, need main shaft 4 motionless, servomotor 6 stops operating; Then pass through pressure oil clamping spindle 4, clamp, so work spindle 4 has the axial float of trace when clamping, so main shaft 4 supports can only be realized by homemade intensive bearing 3 because its form is an end face by homemade film oil cylinder 5; When the workpiece calibration, then loosen film oil cylinder 5, drive main shaft 4 transmissions by servomotor 6, but in transmission process; Because can there be the gap in gear drive, makes indexing accuracy be difficult to reach finishing requirements.Owing to the film oil cylinder 5 homemade reason of workpiece clamp locking oil cylinder in supporting with it, belong to non-standard equipment in addition, be not easy to change in case damage, make and follow-up use in cause the increase of cost.
The utility model content
The problem that the utility model will solve provides and a kind ofly can realize precision round subsection, and critical component all adopts the workpiece box of the numerical control gear-broach machine finishing machine that standard component constitutes.
The technical scheme of the utility model is following: a kind of workpiece box of numerical control gear-broach machine finishing machine; Comprise main shaft, it is characterized in that also comprising torque motor, turntable bearing, thrust ball bearing, end cap, main shaft-linking sleeve, grating chi, workpiece casing, casing bonnet and workpiece clamp locking oil cylinder; Comprise stator and rotor in the said torque motor; Said rotor is connected through screw with main shaft; Said front-end of spindle is connected with the turntable bearing, and rear-end of spindle is connected with thrust ball bearing; The rear end of said main shaft connects end cap and main shaft-linking sleeve simultaneously with screw; Said end cap is provided with the grating chi; Said stator is connected with workpiece casing screw; Said casing bonnet and workpiece box body and function screw are fixed; The rear end of said main shaft-linking sleeve is connected with the workpiece clamp locking oil cylinder.
Further, said thrust ball bearing is installed in the casing bonnet.
The beneficial effect of the utility model is: realized that through said structure main shaft is controlled by torque motor in the engineering of cutting, kept main shaft motionless; During the workpiece calibration,, realize the transmission of no gap, realize high-precision calibration because torque motor is direct-connected.And critical component is all taked standarized component in entire equipment, in the future repair and replacement brought convenient.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model is made critical explanation.
A kind of workpiece box of numerical control gear-broach machine finishing machine is like Fig. 1, shown in Figure 2, in the process of whole lathe; Workpiece box main shaft 4 requires to stop to carry out within some seconds the cutting of workpiece; Require main shaft 4 rotation within time seldom to accomplish the workpiece calibration afterwards, and then stop cutting; Rotation again, calibration ...When needs main shaft 4 rotates; Control by digital control system; Make the torque motor energising, at this moment the rotor 7 of torque motor rotates, and rotor 7 directly is connected with several screws of work spindle 4 usefulness; Main shaft 4 front ends bear two rightabout cutting force power through turntable bearing 9, and main shaft 4 rear ends use thrust ball bearing 10 as supplemental support.Because it is direct-connected with main shaft 4; So realize work spindle 4 no gap transmissions; Be connected simultaneously with main shaft-linking sleeve 12 with end cap 11 with screw in main shaft 4 rear ends simultaneously; Purpose is that grating chi 13 is installed on end cap 11, and the purpose that main shaft-linking sleeve 12 is installed is to be used to install damping mechanism, makes work spindle 4 in the process of work, keep highly steady.And torque motor stator 8 connects with several screws of workpiece casing 16 usefulness, and is fixed.Said thrust ball bearing 10 is installed in the casing bonnet 14, and casing bonnet 14 is fixed with workpiece box body and function screw.On casing bonnet 14, damping mechanism is housed, the size of damping is by structure control.During work, promote the piston 17 of both sides, make piston 17 and main shaft-linking sleeve 12 form friction, promptly realize the stationarity of work through hydraulic oil (trace).At main shaft-linking sleeve 12 rear end joining work pieces clamping cylinders 15.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
