Description
Technical field
The present invention relates to gear manufacturing techniques field, be specifically related to the adjustable drive mechanism in a kind of angular orientation.
Background technique
Miniature missile engine health ignition mechanism generally adopts electric ignition pattern, general in order to ensure the safety of carrier aircraft, adopt the ignition switch of driving structure to ignition mechanism to control, ignition switch is moved limited angle, make igniter away from powder column, rotate to home.For motor-driven Design of Mechanical Structure, rotation angle can be ensured, but carry out accurately controlling but to be difficult to realize to two limit positions of motion, the required precision in driving structure design elements of usual needs is very high could be realized, realize cost high, the accumulative meeting of part tolerance particularly forming mechanism produces considerable influence to movement position.
Summary of the invention
For solving the problems of the technologies described above, the invention provides the adjustable drive mechanism in a kind of angular orientation, the adjustable drive mechanism in this angular orientation is by being separated the function of adjustment angle with drive mechanism body, realize separately the adjustment of angular orientation, solve required precision in driving structure design elements very high, realize the problem that cost is high.
Such design proposal can reduce the impact of element precision on mechanism
The present invention is achieved by the following technical programs.
The adjustable drive mechanism in a kind of angular orientation provided by the invention, comprise mandrel, driving component, driving pin and coupling, described driving component is arranged on mandrel; The madial wall of described mandrel offers arc groove A vertically; Described coupling is installed in mandrel, and the outer side wall of described coupling offers arc groove B vertically, and described driving pin is inserted in the hole be made up of arc groove A and arc groove B.
Also be provided with back-up ring in described mandrel, and back-up ring is placed in the left end of driving pin.
Described driving component is gear or turbine.
The number differences value 2 ~ 5 of described arc groove A and arc groove B.
Beneficial effect of the present invention is: on mandrel and the coupling that coordinates with mandrel, arrange arc groove, and realizes transmission by inserting driving pin in the hole that arc groove A and arc groove B is formed; The angle of this structural adjustment is tilt fixing, carries out angle precision adjustment by the adjustment arc groove B quantity of coupling and the arc groove A quantity of mandrel; The function of adjustment angle is separated with drive mechanism body, realizes separately the adjustment of angular orientation, the requirement of driving mechanism to element precision can be reduced, reduce complete machine cost of production, angle position is arbitrarily adjusted, and the corner not by structure itself limits, this is simple and reliable for structure, and maintenance is strong.

Embodiment
Further describe technological scheme of the present invention below, but described in claimed scope is not limited to.
The adjustable drive mechanism in a kind of angular orientation as shown in FIG. 1 to 3, comprises mandrel 1, driving component 2, driving pin 3 and coupling 4, and described driving component 2 is arranged on mandrel 1; The madial wall of described mandrel 1 offers arc groove A11 vertically; Described coupling 4 is installed in mandrel 1, and the outer side wall of described coupling 4 offers arc groove B41 vertically, and described driving pin 3 is inserted in the hole be made up of arc groove A11 and arc groove B41.
Also be provided with back-up ring 5 in described mandrel 1, and back-up ring 5 is placed in the left end of driving pin 3.Ensure that driving pin 3 is not deviate from the hole be made up of the arc groove A11 of mandrel 1 and the arc groove B41 of coupling 4.
The present invention, primarily of mandrel 1, driving component 2, driving pin 3, coupling 4 and back-up ring 5 five part composition, adjusts angular orientation by the adjustment mounting point of coupling 4 between mandrel 1.Coupling 4 loads in mandrel 1, then is inserted in by driving pin 3 in the hole that is made up of arc groove A11 and arc groove B41, by driving pin 3 transferring power between mandrel and coupling.The power of input is passed to mandrel 1 by driving component 2, then is passed to coupling 4 by driving pin 3, thus drives the live axle being delivered to actuator with coupling 4; Described driving component 2 can be gear or turbine.
Adopt the angle of this structural adjustment to be tilt fixing, by arranging the arc groove B of varying number on coupling 4, the arc groove A arranging varying number in mandrel carries out angle precision adjustment.The quantity of the arc groove A11 on described the mandrel 1 and arc groove B41 on coupling 4 is odd, even not to be limit, and the two difference is more than or equal to 2.If the quantity of arc groove A is n on mandrel 1, on coupling, the quantity of arc groove B is n+a, a is the difference of the quantity of arc groove A and the quantity of arc groove B, then adjustable minimum angles is 360a/ (n (n+a)), as got 18 as n, a is when getting 2, and adjustable minimum angles is 720/360=2 °.By that analogy, if desired adjust less angle, namely need higher angular adjustment precision, then the quantity of increase arc groove A11 that can be suitable and arc groove B41.Otherwise then can reduce angular adjustment precision.The difference range of arc groove quantity need consider the coupling taking into account location and minimum adjustment angle, value 2 ~ 5.The moment size transmitted required for mechanism determines the number differences of arc groove A and arc groove B.
The function of adjustment angle is separated with drive mechanism body by the present invention, realizes separately the adjustment of angular orientation, can reduce the requirement of driving mechanism to element precision, reduce complete machine cost of production, angle position is arbitrarily adjusted, and the corner not by structure itself limits, this is simple and reliable for structure, and maintenance is strong.
