Detailed description of the invention
For ease of explanation the utility model represented central idea in above-mentioned novel content one hurdle, hereby express with specific embodiment.In embodiment, various different objects are in the ratio that is suitable for enumerating explanation, but not are drawn in the ratio of actual components, close first chat bright.
Refer to shown in Fig. 1 to Fig. 3, the utility model provides a kind of index dial 100 that promotes brake effect, and it comprises a pedestal 10, a main shaft 20, a rotating disk platform 30, a driven unit 40, a brake gear 50 and a Power Component.
Driven unit 40, it is in order to drive shaft 20, system comprises a worm gear 41, a worm screw 42 and a motor 43, worm gear 41 is located on main shaft 20, worm screw 42 is positioned at pedestal 10 and engages with worm gear 41, and motor 43 is located at pedestal 10 outsides, can drives worm screw 42 by motor 43, and then main shaft 20 and rotating disk platform 30 are rotated.
Brake gear 50, itself and main shaft 20 combinations, and be located between main shaft 20 and rear shaft-cup 12, system comprises a piston plate 51, a large brake disc 52 and a little brake disc 53, wherein, little brake disc 53 is fixed on main shaft 20 rear ends, can be along with main shaft 20 rotates, piston plate 51 can be incorporated into rear shaft-cup 12 inner sides axially and movably, and large brake disc 52 is through specially treated, for example pass through a heat treated elastic steel sheet, and between little brake disc 53 and piston plate 51, its schematic appearance and profile can be consulted shown in Fig. 4 and Fig. 5,5A.Large brake disc 52 has some perforations 54 that uniformly-spaced arrange and some strip holes 55 uniformly-spaced arranging, it is to see through perforation 54 to be locked on pedestal 10, in the time that main shaft 20 rotates, large brake disc 52 does not contact with little brake disc 53, and strip hole 55 can be located at perforation 54 sides one to one, can reduce the rigidity of large brake disc 52 by strip hole 55, increase its stressed deflection.
Power Component, it is to drive brake gear 50 to act on vapour-pressure type, has the position of driving and does not drive position, is positioned at while driving position and can makes piston plate 51 promote large brake disc 52, make large brake disc 52 and little brake disc 53 CONTACT WITH FRICTION, and then main shaft 20 and rotating disk platform 30 are stopped operating.
Operating principle of the present utility model and implementation method, refer to shown in Fig. 2, Fig. 3 and Fig. 5, can drive worm screw 42, and rotate worm gear 41 by worm screw 42, and then drive shaft 20 and rotating disk platform 30 rotates when user's starter 43, reaches the function of index dial 100.While brake as needs, controlled brake force assembly is positioned at and drives position, can make piston plate 51 promote large brake disc 52, and then make large brake disc 52 and little brake disc 53 CONTACT WITH FRICTION, so just main shaft 20 can be limited immediately and rotating disk platform 30 rotates, and large brake disc 52 of the present utility model is because having some strip holes 55 that uniformly-spaced arrange, can make large brake disc 52 less rigid, can increase at stressed identical lower its deflection, therefore, large brake disc 52 is increased by the deflection after piston plate 51 promotes, large brake disc 52 is contacted with little brake disc 53 with a plane, and then the contact area between large brake disc 52 and little brake disc 53 is increased, can immediately reach effective brake function, make overall brake device 50 brake effect promote.
Otherwise if when main shaft 20 need to rotate again, controlled brake force assembly is positioned at and does not drive position, large brake disc 52 is separated with little brake disc 53, can make main shaft 20 and rotating disk platform 30 again rotate.
In sum, the utility model provides a kind of index dial 100 that promotes brake effect, large brake disc 52 in its brake gear 50 has some strip holes 55 that uniformly-spaced arrange, can reduce the rigidity of large brake disc 52, increase its stressed deflection, therefore, when brake gear 50 of the present utility model brakes, large brake disc 52 contacts with little brake disc 53 with a plane, compared with known brake disc, large brake disc 52 of the present utility model increases with the contact area of little brake disc 53, make brake gear 50 can immediately reach effective brake function, therefore can improve the accuracy of index dial 100 mark calibration location, and then the processing precision of products of making is increased.
Above illustrated embodiment is only in order to the utility model to be described, non-in order to limit scope of the present utility model.Such as do not disobey various modifications or the variation that the utility model spirit is engaged in, all belong to the utility model and be intended to the category of protecting.
