Detailed description of the invention
Embodiment 1:
Process on milling machine to overcome existing monodentate, crudy is by the line precision of skilled worker and the manual operations of skilled worker, each chain nest must be processed by centering, the problem that production efficiency is low, present embodiments provide a kind of as Fig. 1, Fig. 2, heavy scraper conveyor sprocket wheel milling fixture shown in Fig. 3 and Fig. 4, comprise pressing plate 1, mill teeth positioning table 9, and be fixedly connected with screw rod 2 and the nut 3 of pressing plate 1 and mill teeth positioning table 9, described mill teeth positioning table 9 is fixed on Manual rotary platform 10 by alignment pin, mandrel 8 and spline housing 5 is provided with between described pressing plate 1 and mill teeth positioning table 9, spline housing 5 is fixedly sleeved on the lateral surface of mandrel 8, mandrel 8 is fixed on mill teeth positioning table 9 through mandrel 8 medial surface by described screw rod 2, distance between described pressing plate 1 and mill teeth positioning table 9 is that right sprocket wheel 6 and left sprocket wheel 7 superpose the height placed, the lateral surface of described spline housing 5 is provided with the spline tooth matched with right sprocket wheel 6 and left sprocket wheel 7 upper spline hole.
Wherein in order to pressing plate 1 and can be more fastening between screw rod 2 and nut 3, between described pressing plate 1 and nut 3, packing ring 4 is installed.
Add man-hour, left sprocket wheel 7 does positioning reference holes and positioning datum groove, to be connected with mill teeth positioning table 9, alignment pin circumference is first utilized by mill teeth positioning table 9 to be positioned on Manual rotary platform 10, left sprocket wheel 7 left side is arranged on mill teeth positioning table 9, and the spline tooth of spline housing 5 is contained in the splined hole of left sprocket wheel 7, align datum tooth, the inner side of spline housing 5 loads mandrel 8, then, the splined hole of right sprocket wheel 6 and the spline tooth of spline housing 5 are assembled, right side and left sprocket wheel 7 right side of right sprocket wheel 6 fasten, three benchmark spline tooths must align, mill teeth does at left sprocket wheel 7 and right sprocket wheel 6 right side respectively after falling to living and forever matches mark, finally load onto pressing plate 1 successively, packing ring 4, screw rod 2, finally go up jack panel 3.
During work, in mill teeth process, milling cutter only does the milling campaign of repetition; Vertical and horizontal motion done by workbench, the center line of gear is drawn standard, just accurately can locate the relative position of Manual rotary platform 10 and the gear teeth, then, after processing a perpendicular row tooth, stop length feed, cutter back to zero, manually sprocket teeth is adjusted on the accurate location of the tooth that the next one will be processed by panoramic table 10; As long as centering once like this, just sprocket wheel can be processed, and after processing, each profile of tooth of sprocket wheel and tooth nest one to be made peace decile; The raising of the surface quality tens times of chain nest, no longer carries out reconditioning process with pincers worker, therefore, can produce processing in enormous quantities, can reduce friction to greatest extent, improves the quality of sprocket wheel and cuts down finished cost.
Left and right sprocket wheel is the coaxial couple interconnected in chain wheel assembly, this two part interconnects by the involute spline on cylinder surface in two ends on axle, transmitting torque and motion, process so with spline mandrel two sprocket wheels must be linked together when machining chain form of gear tooth and chain nest, the uniformity when product guarantee processed like this uses simultaneously.
Embodiment 2:
On the basis of embodiment 1, described mandrel 8 and screw rod 2 are integrated or Split type structure.Ordinary circumstance, the clamping of fixture can adopt screw rod-pressing plate composition, and this fixture in order to locate more accurately, and guarantees that sprocket wheel circumference does not occur in process and rotates, can also clamp, preferably, mandrel 8 and screw rod 2 are structure as a whole, as shown in Figure 5, screw rod 2 interlude and mandrel 8 one are processed, mandrel 8 is stretched out at screw rod 2 two ends, and top and bottom are provided with screw thread, to be fixedly connected with pressing plate 1 and mill teeth positioning table 9.The center of described mill teeth positioning table 9 is provided with the internal thread be fixedly connected with screw rod 2; The center of described Manual rotary platform 10 is provided with the internal thread be fixedly connected with screw rod 2; The lower end of screw rod 2, through mill teeth positioning table 9, is fixed in the internal thread of Manual rotary platform 10.
And adding man-hour, in order to more accurately sprocket teeth be adjusted on the accurate location of the tooth that will process sooner, described Manual rotary platform 10 is provided with the equation graduation of 0 ° ~ 360 °, described Manual rotary platform 10 is arranged on Manual rotary platform base 11, only the center line of gear need be drawn standard, just accurately can locate Manual rotary platform 10 and the relative position of the gear teeth, by the corresponding angle of rotation manual panoramic table 10, just sprocket teeth can be adjusted on the accurate location of the tooth that the next one will be processed.
In addition, because flat key connects for more fragile piece surface easily by conquassation be worn, as shown in Figure 4, the spline tooth of described spline housing 5 is provided with the inclination angle of 15 °, to engage with sprocket wheel, nor sprocket wheel can be made to suppress in fixture extremely.
Spline housing 5 is better driven to rotate in order to make mandrel 8 when rotation manual panoramic table 10, the medial surface of described spline housing 5 is provided with multiple keyway, mandrel 8 outer surface is provided with multiple key tooth matched with the keyway of spline housing 5, the key tooth of mandrel 8 is fastened in the keyway of spline housing 5, when circumference rotation does not occur mandrel 8, there is not circumference yet and rotate in spline housing 5, therefore, in order to coordinate with spline housing 5, also would not there is circumference and rotate in left sprocket wheel 7 and right sprocket wheel 6.
This fixture is not restricted to a kind of sprocket wheel of model, different according to the model of sprocket wheel to be processed, and the diameter of bore of each sprocket wheel, the spline housing of the various model sprocket wheel of configurable processing; During use, mandrel 8 is constant, changes the spline housing 5 will processing model sprocket wheel, then puts pressing plate 1, packing ring 4, screw rod 2, fastening nut 3.
In sum, two pieces sprocket wheel clamped one time processing in left and right survives by this heavy scraper conveyor sprocket wheel milling fixture that the utility model provides, both the chain nest size of two sprocket wheels, the uniformity of precision had been ensure that, in turn ensure that the uniformity of assembling, the more important thing is, substantially increase production efficiency, and this fixture is not only only limited to a kind of model, also can carry out clamping to other sprocket wheel used in groups, especially there is practicality.
More than exemplifying is only illustrate of the present utility model, does not form the restriction to protection domain of the present utility model, everyly all belongs within protection scope of the present invention with the same or analogous design of the utility model.
