Description
Technical field
The utility model relates to a kind of frock measuring the shearing strength (simple shear) of little external diameter securing member, belongs to securing member shearing strength and measures frock technical field.
Background technology
Securing member commercially also referred to as standard component, be two or more part (or component) is fastenedly connected become one overall time the general name of class mechanical component that adopts.Its feature is that description is various, and performance purposes is different, and standardization, seriation, unitized strong.Concerning the difference due to the field that uses and position securing member, it also has different requirement to shearing strength, and in order to ensure that securing member has enough shearing strengths, most securing member all will through the test of shearing strength.For the securing member of Aero-Space, because its strength ratio is higher, larger to the infringement of frock during measurement.Particularly conventional two pieces of frocks are directly measured at present, its shearing perforation easily damages, and the frock after damage can not be repaired substantially, regenerative ratio can increase cost again, and the sheared edge of common method frock when measuring is fixing now, and a direction in aperture can only be used as sheared edge, the serviceable life of frock greatly can be shortened like this when measuring, simultaneously due to wearing and tearing and the damage of frock, cause frock to cause larger error when double measurement to the result measured, impact judges.In addition, what existing frock mainly adopted is sliding friction, and shearing force by the impact of external force, can affect the accuracy of result.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of frock measuring securing member shearing strength, the sliding friction of slide block is sheared and is improved to rolling friction shearing, greatly can reduce the impact of external force on measurement result, increase the measured intensity of frock, improve the measuring accuracy of frock; Existing shearing perforation is improved to jacking block simultaneously, the serviceable life of frock can be increased, and further improve the precision of frock, to overcome the deficiencies in the prior art.
The technical solution of the utility model: a kind of frock measuring securing member shearing strength, comprise two bases, described base is provided with flat bottomed recess, bottom flat bottomed recess, be provided with jacking block; Two bases are fitted together to mutually, and time chimeric, the jacking block of two bases staggers mutually, and the outer contacting face of two bases is provided with outer rolling rubbing device and locking device; The jacking block mutually staggered is placed with riveted plating, and riveted plating both sides are all connected with the interior opposite face of two bases by interior rolling friction device.
Described outer rolling rubbing device comprises outer steel ball, cross through hole, straight pin, support pressing plate when being arranged on chimeric in chassis outer side, support pressing plate to be connected with straight pin outer end, straight pin is contacted with another chassis outer side face by the outer steel ball be placed in cross through hole, wherein place the cross through hole tail end of outer steel ball for convergence end, when straight pin compresses outer steel ball, outer steel ball has partial denudation to go out convergence end, and can not make a clean sweep of out from this convergence.
Horizontal screw when described locking device comprises stud, wing nut and is arranged on chimeric in chassis outer side, stud one end and horizontal screw are connected, and the other end and wing nut are connected.
Described stud, through supporting pressing plate, when two bases are mutually chimeric, rotate wing nut and can compress support pressing plate and straight pin, thus drive the outer steel ball be arranged in the cross through hole of base side to press to another chassis outer side face.The ingenious cooperation of locking device and outer rolling rubbing device, had both been convenient to shear the operation of measuring, had greatly reduced manufacturing cost again.
Described interior rolling friction device comprises the right angle back up pad of interior steel ball and band round tube hole, interior steel ball is arranged in the round tube hole of right angle back up pad, and when right angle back up pad is fixed on inside base flat bottomed recess, interior steel ball part to contact with riveted plating by round tube hole and forms rolling friction, and the round tube hole outer end of right angle back up pad is convergence end, when right angle back up pad is fixed on inside base flat bottomed recess, interior steel ball has partial denudation to go out this convergence end, and can not make a clean sweep of out from this convergence.This kind of structure has structure simply, the advantages such as installation, maintenance is convenient.
The mount pad of described right angle back up pad is fixed on by dormant screw, steel spring sheet on the end face of the flat bottomed recess opposite side relative with base cross through hole, and it is simple that this fixed form has structure, the advantage that reliability is strong.
The semi-circular groove of longitudinal direction is provided with in described base flat bottomed recess inside another relative with being provided with cross through hole side, the longitudinal fluting of the semi-circular recess with this longitudinal direction is provided with in the middle part of right angle back up pad, when the riveted joint place out-of-flatness of riveted plating, this kind of structure can ensure the smooth and easy shearing of riveted plating, reduces out-of-flatness place to the impact of test findings.
Round tube hole in described right angle back up pad is arranged in longitudinal fluting both sides, and this kind of structure can improve the reliability and stability of interior rolling friction.
The beneficial effects of the utility model are:
The utility model is by being mutually entrenched togather two bases of band flat bottomed recess, locking device and outer rolling rubbing device is arranged in its outer contacting face, within it opposite face arranges interior rolling friction device, like this riveted plating is placed on jacking block place when measuring, traditional skid fricting shearing can be improved to rolling friction to shear, and then can reduce friction, get rid of external force to the impact of measurement result, improve the measuring accuracy of frock.Simultaneously owing to adopting jacking block to instead of existing shearing perforation, this kind of structure also can increase the serviceable life of frock, and further improves precision and the measured intensity of frock.
In addition, when measuring combination fasteners, because combination fasteners length dimension is different, traditional method needs, for each product is equipped with a set of shearing frock, so not only can cause waste when measuring, and inefficiency.After adopting the utility model, the part for different length only needs the shear plate of replacing one piece of different-thickness, and thus the utility model also has the advantage that adaptation is wide and can increase work efficiency.The utility model is particularly suitable for the shear resistance that measurement external diameter φ 2-φ 10 length is less than 35 securing members.
