The carriage mechanism comprises a medium sliding plate, a rotary plate body, a gear plate, a rack and a feed cylinder. The gear plate connected with the rotary plate body is installed on the medium sliding plate, and the rack meshed with the gear plate is connected with the feed cylinder. The carriage mechanism on the spherical machine tool is simple in structure, achieves high accuracy of rotation of a knife rest, and improves machining quality of spherical bearings.
Description
Technical field
The present invention relates to sphere machine tool technical field, especially with a kind of sphere lathe on dragging plate mechanism relevant.
Background technology
Bearing works the parts of fixing and reducing the load coefficient of friction in mechanical transmission course.Most of bearings all be the surface for columned structure, but some different bearings are also arranged, such as conical bearing, its surperficial frustum cone structure has certain taper, spherical bearing and for example, its surface is the ball shape structure.
The bearing lathe all is to adopt oil cylinder directly to act directly on the rotating disk knife rest to the processing turning mode of spherical bearing at present, the rotation of the extension and contraction control rotating disk knife rest of oil cylinder, thus making to be fixed on the rotating disk knife rest rotates, and bearing is carried out Curve Machining.
Because the piston rod of oil cylinder is flexible to be straight path, acts directly on like this on the rotating disk knife rest, the rotary motion trace of rotating disk knife rest is limited all the time, and precision is not high.Therefore the inventor has carried out improving to dragging plate mechanism to this problem, and this case produces thus.
Summary of the invention
The purpose of this invention is to provide the dragging plate mechanism on a kind of sphere lathe, simple in structure, realize that the blade holder turns precision is high, improves the spherical bearing crudy.
In order to achieve the above object, the present invention realizes through following technical scheme:
Dragging plate mechanism on a kind of sphere lathe comprises middle slide plate, rotary case, toothed disc, tooth bar, feed oil cylinder; The rotary case that is connected with toothed disc is installed on the middle slide plate, is connected with the feed oil cylinder with the tooth bar of toothed disc engagement.
Described middle slide plate is slidingly connected on the planker base, and vertically oil cylinder is fixed on the middle slide plate, and vertically the mandrel of oil cylinder is connected with the planker base.
On the described middle slide plate adjustable plate is installed, bearing block is fixed on the adjustable plate, and angular contact bearing and taper roll bearing are housed in the bearing block; Toothed disc passes angular contact bearing and taper roll bearing, locks with locking nut in the taper roll bearing lower end.
Described rotary case is fixed on the toothed disc top.
The knife rest of fixed cutting tool is installed on the described rotary case.
Described feed oil cylinder is fixed on the middle slide plate.
After adopting such scheme, the present invention has many beneficial effects:
The mode that among the present invention original oil cylinder is directly connected the rotating disk tool rest; Change over the mode that adopts toothed disc and tooth bar engagement and control the rotation of cutter; Toothed disc and tooth bar engaged transmission; Rectilinear motion is transformed into circular motion, is applied on the sphere lathe, make the spherical turning TRAJECTORY CONTROL more accurate.
Description of drawings
Fig. 1 is the vertical view of preferred embodiment of the present invention;
Fig. 2 be among Fig. 1 A-A to sketch map;
Fig. 3 be among Fig. 2 B-B to sketch map.
The specific embodiment
In conjunction with accompanying drawing, preferred embodiment of the present invention is explained further details.
Dragging plate mechanism on a kind of sphere lathe, the parts that are mainly concerned with comprise planker base 1, vertical oil cylinder 2, middle slide plate 3, rotary case 4, toothed disc 5, tooth bar 6, feed oil cylinder 7.
The upper surface of middle slide plate 3 is fixed with an adjustable plate 8; Bearing block 9 is installed on the adjustable plate 8; Angular contact bearing 10 and taper roll bearing 11 are installed in the bearing block 9, and wherein taper roll bearing 11 is positioned at the bottom of bearing block 9, and angular contact bearing 10 is positioned at taper roll bearing 11 tops; Toothed disc 5 passes angular contact bearing 10 and taper roll bearing 11 packs in the bearing block 9, locks with locking nut 13 in taper roll bearing 11 lower ends simultaneously.The part of exposing bearing block 5 of toothed disc 5 is a circle gear, just is meshing with each other with tooth bar 6.One end of tooth bar 6 is connected with the mandrel of feed oil cylinder 7.Feed oil cylinder 7 also is fixed on the middle slide plate 3.Rotary case 4 is fixed on the top end face of toothed disc, and the knife rest 12 that is used for fixing cutter is installed on it.
Operation principle of the present invention be for:
1: the feed order: planker base 1 is fixing; Vertically the mandrel of oil cylinder 2 begins to stretch out motion (vertically oil cylinder 2 is initially located in retracted mode); Promote middle slide plate 3 and longitudinally moving on oil cylinder 2 centerline directions, thereby drive middle slide plate all parts and then middle slide plate 3 motions together more than 3.When toothed disc 5 centers arrive the precalculated position; Vertically oil cylinder 2 stop motions this moment, feed oil cylinder 7 beginning retraction movement (feed oil cylinder 7 is initially located in the state of stretching out), pulling tooth bar 6 is along moving on feed oil cylinder 7 centerline directions; Thereby driven gear dish 5 is made circular motion along the common center line of toothed disc 5, angular contact bearing 10 and taper roll bearing 11; Drive rotary case 4 and make circular motion, make circular motion thereby drive the smear metal cutter, and reach the effect of processing sphere with knife rest 12.
2, withdrawing order: vertically oil cylinder 2 beginnings make the motion in the other direction of whole middle slide plate 3, away from converted products toward the reset condition motion; After arriving the home position; Vertically oil cylinder 2 stops, and 7 beginnings of feed oil cylinder make toothed disc 5, rotary case 4 and knife rest 12 make circular motion in the other direction toward the reset condition motion; After arriving the home position, feed oil cylinder 7 stops.Work period of this moment accomplishes, and waits for the beginning of next work period.
The foregoing description only is used to the inventive concept of the present invention of explaining, but not to the qualification of rights protection of the present invention, allly utilizes this design that the present invention is carried out the change of unsubstantiality, all should fall into protection scope of the present invention.
