Abstract
The utility model discloses a machinery stop gear, including graduation piece, gyro wheel and resilient means, the surface profile of graduation piece and the movement track of the motion structure among the mechanical structure suit, and it has the recess that is used for blocking the gyro wheel to open in spacing department, and the non - motion that the graduation piece was installed in mechanical structure is structural, the motion that the gyro wheel was installed in mechanical structure is structural, and the motion structure is passed through the gyro wheel and is rolled on the graduation piece, rolls when getting into the recess of graduation piece when the gyro wheel, realizes the spacing of structure of moving, resilient means installs in the motion structurally, provides the pretightning force for the gyro wheel. This stop gear has that the mechanism is simple, easily operation, advantage such as reliable durable, but the wide application realizes the limit function that machinery used in various machineries.
Description
Technical field
The utility model relates to a kind of limit structure in mechanical structure, specifically a kind of mechanical position limitation mechanism.
Background technique
For satisfied use needs and designing requirement, the motion structure in a part of machinery is when making mechanical movement, and often need some special position on its movement locus to realize fixed function, this just requires that it has position-limit mechanism.As shown in Figure 2, motion structure is a paver operating floor runing rest 6, and runing rest 6 is in fixed plate 7(non-athletic mechanism) upper rotation, in order to limit the slewing area of runing rest 6, need to arrange position-limit mechanism.And consider for the Economy of machinery own and adaptability, such position-limit mechanism should be tried one's best simply, is easy to operation, reliability and durability.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of mechanical position limitation mechanism, not only meets mechanical position limitation function, and simple and reliable, is easy to operation, durable.
To achieve these goals, a kind of mechanical position limitation mechanism of the utility model, comprises calibration block, roller and elastic device; The movement locus of the motion structure in the surface profile of described calibration block and mechanical structure adapts, and have the groove for blocking roller at spacing place, calibration block is arranged in the non-athletic structure in mechanical structure; Described roller is arranged on the motion structure in mechanical structure, and motion structure is rolled on calibration block by roller, when roller rolling enters the groove of calibration block, realizes the spacing of motion structure; Described elastic device is arranged on motion structure, for roller provides pretightening force.
Further, described motion structure is paver operating floor runing rest, and described non-athletic structure is fixed plate, and described calibration block is arc with the profile of roller contact.
Further, described elastic device comprises spring, pressing plate and bolt, and described spring is arranged on pressing plate by bolt; Described pressing plate is fixed on motion structure, and is connected with roller.
The movement locus of the motion structure in the surface profile of the utility model calibration block and mechanical structure adapts, and is designed with the groove of special position, is arranged in the non-athletic structure in mechanical structure; Roller is arranged on the motion structure in mechanical structure, and roller rolls on calibration block, when roller rolling enters the groove of calibration block, realizes the limit function of motion structure; Elastic device acts on roller, for roller provides certain pretightening force, roller can not be deviate from easily in the groove of calibration block, this position-limit mechanism have mechanism simple, be easy to operation, the advantage such as reliability and durability, can be widely used in various machinery, realize the limit function that machinery uses.

Fig. 2 is paver operating floor rotational structure;
In figure: 1, calibration block, 2, roller, 3, spring, 4, pressing plate, 5, bolt, 6, runing rest, 7, fixed plate.
Embodiment
In order to make those skilled in the art person understand the utility model scheme better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the utility model mechanical position limitation mechanism, comprises calibration block 1, roller 2 and elastic device; The movement locus of the motion structure in the surface profile of calibration block 1 and mechanical structure adapts, and have the groove for blocking roller 2 at spacing place, calibration block 1 is arranged in the non-athletic structure in mechanical structure; Roller 2 is arranged on the motion structure in mechanical structure, and motion structure is rolled on calibration block 1 by roller 2, when roller 2 rolling enters the groove of calibration block, realizes the spacing of motion structure; Elastic device is arranged on motion structure, for roller provides pretightening force, roller can not be deviate from easily in the groove of calibration block.
It is circular implementation column that the utility model provides a kind of movement locus, and as depicted in figs. 1 and 2, motion structure is paver operating floor runing rest 6, and non-athletic structure is fixed plate 7, and the profile that calibration block 1 contacts with roller 2 is arc.Runing rest 6 is rotated at calibration block 1 by roller 2, its movement locus is circular, when roller 2 enters the groove on calibration block 1, for roller provides pretightening force, roller 2 can not be deviate from easily in the groove of calibration block 1, thus realize the position fixed function of motion structure.
The utility model provides a kind of implementation column of elastic device further, and elastic device comprises spring 3, pressing plate 4 and bolt 5, and described spring 3 is arranged on pressing plate 4 by bolt 5; Described pressing plate 4 is fixed on motion structure, and is connected with roller 2.
Be more than an example of the present utility model, this case introduction a kind of application scheme of the present utility model.The utility model is not limited to the program, and the movement locus of motion structure is not limited to circular trace, can have any shape track; The shock resistance that calibration block 1, roller 2 can use according to reality, wear resistance and Economy etc. require unrestricted choice material; Elastic device should determine according to the feature of machinery own, realizes, can select implementation voluntarily, be not limited to the spring described in example according to mechanical specific constructive form by various spring and elastic material.The structural type with above-mentioned feature and simple deformation all in scope of the present utility model, should should give protection.
