Description
Technical field
The utility model relates to lathe, especially for the lathe of processing automobile axletree.
Background technology
At present the known lathe that is used for the processing automobile axletree all is to cooperate tailstock by spindle chuck, perhaps cooperates center rest to fix the axletree base substrate by spindle chuck.The cylindrical of processing axletree base substrate, end face, externally threaded the time by an end of spindle chuck clampingc car shaft blank body, hold out against the other end of axletree base substrate by tailstock, in the end face endoporus of processing the axletree base substrate, chamfering, change tailstock into center rest, but no matter hold out against the axletree base substrate and still use center rest supported cart shaft blank body, all can only process an end of axletree base substrate at every turn with tailstock.Therefore, with traditional lathe the two ends of an axletree base substrate being processed above-mentioned overall process just must workpiece loading and unloading four times.
Because mostly between 1650～2550 millimeters, cargo handling process must rely on crane gear for axletree base substrate heaviness and length, therefore with traditional lathe processing axletree ubiquity troublesome poeration, efficient is low, the workshop floor space is big shortcoming.
The utility model content
The purpose of this utility model provides a kind of lathe that is used for the processing automobile axletree, and this lathe only need load and unload once just can finish Vehicle Processing.
The utility model is achieved in that a kind of lathe of processing automobile axletree, comprise the main spindle box of driving axletree base substrate rotation and the tailstock of supported cart shaft blank body, main spindle box comprises an inside spline wheel gear by main motor-driven rotation, the centre hole axis of inside spline wheel gear is a taper hole to an end of perforation and centre bore, the coaxial external splines tapered sleeve that is socketed with of the centre bore of inside spline wheel gear, the external splines tapered sleeve axially connects, the male cone (strobilus masculinus) of external splines tapered sleeve cooperates with the described taper hole of inside spline wheel gear, play the centering effect, the external splines of external splines tapered sleeve inserts in the internal spline of inside spline wheel gear slidably, the centre bore of external splines tapered sleeve has the rectangular opening that matches with axletree base substrate shape of cross section, make the external splines tapered sleeve rotating torque can be passed to the axletree base substrate, described tailstock comprises an axial restraint but the tapered sleeve that can rotate freely, the axial perforation of this tapered sleeve and its axis are coaxial with the axis of the external splines tapered sleeve of described main spindle box, the lathe bed of described tailstock and lathe is slidingly connected, oil cylinder is installed on the lathe bed, and the hydraulic oil cylinder driving tailstock moves along the axis of the tapered sleeve of tailstock.
Selectively, the spline increment of the spline increment of described inside spline wheel gear and described external splines tapered sleeve is an arc surface.
Operation principle of the present utility model is to utilize the tapered sleeve clampingc car shaft blank body of the external splines tapered sleeve of main spindle box with tailstock, and utilize the inside spline wheel gear of main spindle box to be connected with the spline of external splines tapered sleeve, and the cooperating of the shape of cross section of the rectangular opening of external splines tapered sleeve and axletree base substrate, the rotating torque of main motor is passed to the axletree base substrate, realize the rotation of axletree base substrate.Because the two ends to be processed of axletree base substrate can be stretched out from the external splines tapered sleeve of main spindle box and the tapered sleeve of tailstock respectively, therefore only need to install the Vehicle Processing that a time axletree base substrate just can be finished cylindrical, end face, external screw thread, end face endoporus and the chamfering of axletree base substrate.
The utility model has the advantages that and saved the repeatedly loading and unloading of workpiece in process, easy to operate, can improve 4～5 times of work efficiency, reduce the workshop floor space.

The specific embodiment
Fig. 1 is the vertical view of lathe.As shown in Figure 1, the lathe of processing automobile axletree comprises the main spindle box 1 of driving axletree base substrate rotation and the tailstock 2 of supported cart shaft blank body 8.
Referring to Fig. 2, Fig. 3, an inside spline wheel gear 3 by main motor-driven rotation is installed in the main spindle box 1 simultaneously, the centre hole axis of inside spline wheel gear 3 is to perforation.The left end of centre bore is a taper hole.Internal spline 4 is arranged on the right-hand member of centre bore.
Simultaneously referring to Fig. 2, Fig. 4, the coaxial external splines tapered sleeve 5 that is socketed with of the centre bore of inside spline wheel gear 3, external splines tapered sleeve 5 axially connects.External splines 6 is arranged on the right-hand member of external splines tapered sleeve 5.The male cone (strobilus masculinus) 7 of external splines tapered sleeve 5 left ends cooperates with the taper hole of inside spline wheel gear 3, plays the centering effect.The external splines 6 of external splines tapered sleeve 5 inserts in the internal spline 4 of inside spline wheel gear 3 slidably.Inside spline wheel gear 3 passes to external splines tapered sleeve 5 by the spline connection with rotating torque.Referring to Fig. 5, the centre bore of external splines tapered sleeve 5 has the rectangular opening that matches with the shape of cross section of axletree base substrate 8, makes external splines tapered sleeve 5 rotating torque can be passed to axletree base substrate 8.
Referring to Fig. 6, an axial restraint is installed but the tapered sleeve 9 that can rotate freely in the tailstock 2, tapered sleeve 9 axially connect and also its axis coaxial with the axis of the external splines tapered sleeve 5 of main spindle box.
Referring to Fig. 1, be fixed with oil cylinder 10 on the lathe bed, the piston rod of oil cylinder 10 is connected to tailstock 2.Tailstock 2 is slidingly connected with the lathe bed of lathe, and the concrete structure that is slidingly connected can adopt conventional dovetail groove connected mode, offers dovetail groove in tailstock 2 bottoms, fixing swallow-tail form slide block on lathe bed.Oil cylinder 10 can drive tailstock 2 and move around along the axis of the tapered sleeve 9 of tailstock.For ease of the position of adjusting oil cylinder 10, the mode that also can adopt dovetail groove to be slidingly connected between oil cylinder 10 and the lathe bed, and will adjust oil cylinder 10 lockings of position with bolt.
When on lathe, the axletree base substrate being installed, external splines tapered sleeve 5 is taken out an end that is enclosed within the axletree base substrate from the centre bore of inside spline wheel gear 3, then the axletree base substrate is winched to lathe, make the two ends of axletree base substrate roughly align the centre bore of the inside spline wheel gear 3 of main spindle box 1, and the tapered sleeve 9 of tailstock 2, start oil cylinder 10 then, order about tailstock 2 and move to main spindle box 1 and draw close, until the external splines tapered sleeve 5 of main spindle box 1 tapered sleeve 9 axletree base substrate 8 is fixedly clamped, as shown in Figure 1 with tailstock 2.After installing the axletree base substrate, drive 8 rotations of axletree base substrate, simultaneously machining is carried out at the two ends of axletree base substrate 8 by two cover numerical control knife rest assemblies 12,13 shown in Figure 1 by main motor 11.
In the process that the axletree base substrate is installed, when an end of axletree base substrate passed the centre bore of inside spline wheel gear 3, the external splines that is enclosed within the external splines tapered sleeve 5 on the axletree base substrate slided in the internal spline of inside spline wheel gear 3 naturally.For the external splines 6 that makes external splines tapered sleeve 5 can slip in the internal spline 4 of inside spline wheel gear 3 more swimmingly, should be as shown in Figure 7, the spline increment of inside spline wheel gear 3 is made arc surface 14, and should as shown in Figure 8 the spline increment of external splines tapered sleeve 5 also be made arc surface 15.
