Description
Technical field
The invention belongs to technical fields of mechanical processing, and in particular to a kind of shear test frock.
Background technique
In existing product, part, needs to measure shearing strength, such as sunk screw, bolt, be referred to as testpieces.?
When carrying out shearing test to testpieces, inevitably need to use tooling to realize the company between puller system and testpieces
It connects.Such as application No. is the real new patents of 201420716282.0 China to disclose " a kind of bolt shearing test clamp ", including point
The connector and plate face of body setting extend perpendicularly to the shear plate of left and right directions, are provided with and are used for and testing machine on connector
Connected testing machine connection structure, bolt shearing test clamp further include for shear plate to be connected to the connection when in use
Shearing board connecting structure on part offers the confession of at least one axis extending direction in left-right direction on shear plate accordingly wait try
Test the bolt penetration hole that bolt installs.But this device will appear following problem when in use: 1, due to shear plate and connection
It is connected by screw bolts between part, during shearing test, intensity is inadequate, is easy to appear fracture, and when bolt occurs
When bending, stress changes, the shearing strength tested out can inaccuracy；2, the bolt by two shear plates is needed to wear during installation
Hole alignment, is then inserted into bolt to be tested, very inconvenient；3, when needing to test the shearing strength of single bolt, due to
There was only bolt to be tested between two shear plates, around there is no the structure of positioning, be easy to appear unstable situation.
Summary of the invention
The invention is intended to provide a kind of shear test frock, to solve, present test tool installation is inconvenient, intensity is low, no
Stable problem.
One of this programme shear test frock, including upper cutter, lower cutter and limit assembly, the upper cutter is under
Cutter is integrally formed, and the upper cutter is set on along its length there are two instrument connection side by side, and the upper cutter is being tested
Around hole be equipped with multiple mounting holes, the limit assembly be equipped with multiple through-holes, the mounting hole of the limit assembly with above cut
The through-hole of knife corresponds, and fixing bolt is equipped in corresponding mounting hole and through-hole by limit assembly and the fixed company of upper cutter
It connecing, limit assembly is equipped with the open end for lower cutter insertion, and the lower cutter is equipped with the circular hole to align with instrument connection,
Testpieces is arranged in the instrument connection and circular hole to align, and the limit assembly is equipped with the opening passed through for testpieces.
The working principle of the invention: upper cutter and lower cutter are all made of the structure of a bodily form type, its intensity are improved, right
When testpieces is tested, stress influence is smaller, therefore the shearing strength tested out is more accurate.When operation, mounting hole
It can be adjusted according to actual needs with through-hole, increase or decrease its number, fixing bolt is passed through into the opposite through-hole in position
And mounting hole, limit assembly is fixedly mounted on upper cutter, the open end on limit assembly is inserted into for lower cutter.Due to upper
Cutter is equipped with instrument connection, and lower cutter is equipped with circular hole, and instrument connection and circular hole align, and testpieces is passed through instrument connection and circular hole
, and have the opening passed through for testpieces on limit assembly.The design of two instrument connections can test two tests simultaneously
Part can also test single test part, more practical.By testpieces pass through opening, after being placed in instrument connection and circular hole, by it is upper,
Lower cutter is separately fixed at puller system top and bottom, starts puller system, imposes opposite direction to upper cutter and lower cutter respectively
Pulling force, can to testpieces carry out shearing test, determine its shearing strength.
Beneficial effects of the present invention: main in this programme there are three advantages: one, upper cutter and lower cutter are all made of a bodily form
The structure of type improves its intensity, and when testing testpieces, stress influence is smaller, therefore the shearing resistance tested out
Intensity is more accurate.Two, easy for installation, lower cutter need to be only inserted into limit assembly, without alignment correction repeatedly, operation
Simply.Three, lower cutter is in insertion limit assembly, after having installed testpieces, can rise to testpieces around limit assembly
To the effect for blocking its offset, its stability is improved, test data is more acurrate, due to the raising of testpieces stability, will not lead
Its offset is caused to skid off, therefore operating also can be safer.
Further, the portal structures that the limit assembly is integrally formed, it is such to be advantageous in that very convenient, use
When, only installation need to can be fixed in the through-hole alignment mounting hole on the limit assembly of portal structures, then by lower cutter from
The side insertion that limit assembly is opened, and also there are the structure of door shape enough space openings to pass through to testpieces.
Further, the limit assembly includes two sections of backing plates and two pressure plates, and the backing plate is placed in upper cutter and pressing plate
Between, two sections of backing plates are vertically-mounted and have gap, and the lower cutter is inserted between backing plate from gap location, the pressing plate water
Safety is loaded on backing plate top and is spaced apart from each other, and the backing plate and pressing plate form ring-shaped, and the center is to pass through for testpieces
Opening, the through-hole on the backing plate and pressing plate is respectively there are two more than.Above-mentioned design is advantageous in that, independent using four
Installation part forms limit assembly by cooperating, and each individually backing plate and pressing plate can be processed individually, such as portal structures
Limit assembly for, processing is got up more convenient, and pressing plate is mounted on backing plate, can be with.
Further, the pressing plate is equipped with location hole, is installed with positioning bolt in the location hole above lower cutter.Work as incision
It when knife is inserted into the gap between backing plate, only need to up slide, by adjusting the position of location hole, lower cutter can be allowed to arrive to positioning
After bolt, the circular hole on lower cutter is just aligned with the instrument connection of upper cutter, is installed so very simple and convenient.
