Abstract
The utility model provides a conjugate curve Geneva wheel indexing box, which comprises a box body. An input shaft and an output shaft are supported on the box body in parallel through bearings, an upper shifting pin and a lower shifting pin are fixed to a shifting disk and staggered by 180 degrees, and the shifting disk is fixedly connected with the input shaft. Two Geneva wheels identical in structure are fixed onto the output shaft, conjugate curve guide grooves are distributed along the peripheries of the end surfaces of the Geneva wheels, the two Geneva wheels are oppositely arranged and staggered at a certain inclined angle to be mounted on the output shaft, and the inclined angle is determined by number of divisions. Convex locking arcs are arranged on the periphery of the shifting disk, and concave locking arcs are correspondingly arranged on the Geneva wheels. Linear grooves are substituted by the conjugate curve guide grooves, alternative indexing of the two Geneva wheels can be achieved by means of the upper shifting pin and the lower shifting pin, impaction of linear Geneva wheels and fault moving of curve Geneva wheels can be resolved, power performance can be improved, application range is widened, and indexing according to free laws can be realized theoretically.
Description
Technical field
The utility model belongs to a kind of novel sheave indexing mechanism, relates to conjugate curve Geneva index case.The occasion that it not only can be used for the low speed underloading as common sheave also is suitable for the occasion of carrying in some high speeds.
Background technique
Geneva mechanism has the characteristics of simplicity of design, easy processing, is widely used in the various occasions that need calibration.But traditional straight-line groove wheel mechanism has soft impulse at stroke the whole story, so it often is limited to the calibration of low-medium speed underloading.Though current curve sheave increases than straight-line groove wheel dynamic performance, when on the line of centers of finger at diaxon, the motion of sheave is uncertain, and finger may return along original route, and calibration gets muddled.
Summary of the invention
May I ask topic for the impact that solves the straight-line groove wheel mechanism and the qi of curve sheave mechanism, the utility model proposes conjugate curve Geneva index case.
The technical solution of the utility model is: conjugate curve Geneva index case, comprise a casing, and it is characterized in that: by bearings input shaft and output shaft are arranged on the casing, input shaft and output shaft are arranged in parallel; Last finger and following finger are fixed on the dial, and last finger and following finger interlace 180 ° and arrange that dial is fixedlyed connected with input shaft; Be fixed with two sheaves on the output shaft, the structure of two sheaves is identical, is uniformly distributed along the circumference to be provided with the conjugate curve guide groove two end face sheave positioned opposite on the end face of sheave, two end face sheaves are installed in the output shaft certain included angle that interlaces, and described certain included angle angle is determined by the number of divisions; The outer rim of dial is provided with protruding locking arc, and correspondence is provided with recessed locking arc on the sheave body.
The conjugate curve guide groove is an asymmetric design, preceding half section characteristics of motion design according to the calibration section, and the second half section is a circular arc.
Beneficial effect: the utility model replaces straight-line groove with the conjugate curve guide groove, make two sheaves replace calibration by last finger and following finger, solve the impact of straight-line groove wheel mechanism and the qi of curve sheave mechanism and mayed I ask topic, improved its power performance, enlarged application area, can realize in theory by any rule calibration.

Embodiment
Conjugate curve Geneva index case as shown in Figure 1, 2 comprises a casing 1, by bearings input shaft 6 and output shaft 8 is arranged on the casing 1, and input shaft 6 and output shaft 8 are arranged in parallel; Last finger 5 and following finger 7 are fixed on the dial 2, and last finger 5 and following finger 7 interlace 180 ° and arrange that dial 2 is fixedlyed connected with input shaft 6; Two identical in structure sheaves 9 and sheave 10 are arranged on the output shaft, sheave 9 is fixed on the sheave body 3 with sheave 10, be uniformly distributed along the circumference on the end face of sheave 9 and on the end face of sheave 10 and be provided with conjugate curve guide groove 4, sheave 9 and sheave 10 positioned opposite, sheave 9 and sheave 10 certain included angle that interlaces on output shaft is installed, and described certain included angle is determined by the number of divisions; The outer rim of dial 2 is provided with protruding locking arc, and correspondence is provided with recessed locking arc on the sheave body 3.
Two sheaves certain included angle basis that interlaces is: the angle that the interlaces=360 °/number of divisions.
Conjugate curve guide groove 4 is an asymmetric design, preceding half section characteristics of motion design according to the calibration section, and the second half section is a circular arc.
In theory, the utility model can be realized depending on choosing of conjugate curve guide groove 4 characteristics of motion by any rule calibration, and conjugate curve guide groove 4 can be chosen the characteristics of motion arbitrarily in theory as cam.
