Abstract
The invention discloses a spring cotter pressing force measuring device. The measuring device comprises a force-measuring shear device and a pull and push dynamometer. The force-measuring shear device comprises a supporting arm, a force-measuring arm, a bolt, and a hexagon nut. The supporting arm passes through a rectangular hole of the force-measuring arm, and is connected through the bolt, and is fixed by the hexagon nut. The pull and push dynamometer is connected with a threaded hole on the lower side of the force-measuring arm. Through fixing the supporting arm on a tested product, a spring cotter is compressed by the force-measuring arm, and the pull and push dynamometer can measure elastic force of the spring cotter. The device solves problems of measuring maximum force required to overcome the spring cotter in a work moment of a certain aerospace product component.
Description
Technical field
The present invention relates to measurement mechanism and the measuring method of power, specifically a kind of spring detent snap-in force measurement mechanism and measuring method thereof.
Background technology
Existing certain space product parts operating instant meeting holddown spring lock pin, and utilize the elastic force of spring in spring detent to eject lock pin, thus fix two parts.In order to ensure that these parts can be opened completely, snap-in force when needing measuring spring lock pin to be fully pressed.
Owing to being folded state when these parts are stored, measurement space is limited, and upper and lower measuring distance is only about 20mm.In prior art, lack the measurement mechanism for above-mentioned condition, in order to meet above-mentioned requirements, industry needs to realize meeting the measurement mechanism of related request, realizes the summary of measuring process, visual, improves the requirement reduced while measuring efficiency operating personnel.Do not find explanation or the report of technology similar to the present invention at present, not yet collect similar data both at home and abroad yet.
Summary of the invention
The present invention is directed to above shortcomings in prior art, provide a kind of spring detent snap-in force measurement mechanism, effectively can solve the problem measured and overcome the maximum, force of spring detent needed for space product component working moment.
In order to solve the problem, the present invention is achieved by the following technical solutions, provide a kind of spring detent snap-in force measurement mechanism, comprise dynamometry and cut device and pull and push dynamometer, wherein, described dynamometry is cut device and is comprised sway brace, measuring arm of force, bolt, hex-head nut, and described sway brace is bolted through the hole of measuring arm of force, and fix by hex-head nut, the threaded hole that described pull and push dynamometer and dynamometry are cut in device on the downside of measuring arm of force is connected.
Preferably, described pull and push dynamometer is integral type, and quantity is 1, and maximum range is 200N, and precision is 0.1N.
Another program of the present invention is to propose a kind of spring detent snap-in force measuring method, first sway brace is inserted the position of part respective aperture, then measuring arm of force is placed on spring detent, one hand steered sway brace is motionless, the downward holddown spring lock pin of measuring arm of force is made bottom another hand propelled pull and push dynamometer, pull and push dynamometer can show the snap-in force of spring detent, the maximum snap-in force for spring detent of the pull and push dynamometer display when spring detent is forced into minimum point.
Preferably, utilize lever principle, the power arm of measurement mechanism measuring arm of force and resistance arm are designed to equal length.
Compared with existent technique, the present invention can meet the requirement of measuring spring lock pin snap-in force in small space.The present invention is used for the measurement of spring detent snap-in force, and cutting device by dynamometry can holddown spring lock pin, and pull and push dynamometer shows the snap-in force of spring detent.
Accompanying drawing explanation
Fig. 1 is the assembling schematic diagram that the present invention has the spring detent snap-in force measurement mechanism of digital display function;
Fig. 2 is the spring detent snap-in force measurement mechanism structural representation with digital display function;
In figure: 1 is sway brace, 2 is measuring arm of force, and 3 is bolt, and 4 is nut, and 5 is pull and push dynamometer.
Embodiment
Below embodiments of the invention are elaborated: the present embodiment is implemented under premised on technical solution of the present invention, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
As shown in Figure 1, the present embodiment comprises: comprise dynamometry and cut device and pull and push dynamometer 5, wherein, described dynamometry is cut device and is comprised sway brace 1, measuring arm of force 2, bolt 3, hex-head nut 4, described sway brace 1 is connected by bolt 3 through the rectangular opening of measuring arm of force 2, and fixing with hexagon head spiral shell 4 mother, the threaded hole that described pull and push dynamometer 5 and dynamometry are cut in device on the downside of measuring arm of force 2 is connected.
Further, described pull and push dynamometer 5 is integral type, and quantity is 1, and maximum range is 200N, and precision is 0.1N.
A kind of spring detent snap-in force measuring method, utilizes lever principle, the power arm of measurement mechanism measuring arm of force 2 and resistance arm is designed to equal length.
Preferably, hold described sway brace 1 with the right hand and be fixed on test product motionless, promote bottom described pull and push dynamometer, to drive measuring arm of force 2 holddown spring lock pin with left hand, pull and push dynamometer can show the elastic force of spring detent.
During work, first sway brace 1 is inserted the corresponding position of part, then measuring arm of force 2 is placed on spring detent, one hand steered sway brace 1 is motionless, another hand propelled pull and push dynamometer 5 makes measuring arm of force 2 holddown spring lock pin downwards, now, pull and push dynamometer 5 can show the snap-in force of spring detent, the maximum snap-in force for spring detent of the pull and push dynamometer display when spring detent is forced into minimum point.
Above specific embodiments of the invention are described.It is to be appreciated that the present invention is not limited to above-mentioned particular implementation, those skilled in the art can make various distortion or amendment within the scope of the claims, and this does not affect flesh and blood of the present invention.
