Description
Technical field
It is used for rubber mat plate tensile set the present invention relates to high-speed railway fastener rubber mat plate and tests quick test clamp
Tool.
Background technology
China Express Railway now using the rubber mat plate in fastener system, it is necessary to the sample of Fig. 1 shapes is made, it is necessary to
Two lines at a distance of 25mm of a-quadrant inside-paint, then stretch rubber with fixture, and the two lines at a distance of 25mm are moved to original distance
1.5 times (i.e. 37.5mm), then put into ageing oven experiment, after ageing oven is tested, lay down fixture, record former 25mm gauge length
The spacing L of line, so as to draw tensile set rate.
Existing fixture structure is uncontrollable, is difficult to be stretched to original 1.5 times exactly during stretching, causes to test
Resultant error is big, easily disputes on；And clamping speed is slow.
The content of the invention
In order to overcome the disadvantages mentioned above of prior art, the invention provides a kind of adjustable rubber tensile scrag test
Fixture.
The technical solution adopted for the present invention to solve the technical problems is：A kind of adjustable rubber tensile scrag test
Fixture, including sole-plate and the accurate adjustment sliding block and coarse adjustment sliding block that are arranged on sole-plate, in accurate adjustment sliding block and coarse adjustment sliding block
On be provided with cover plate for clamping rubber parts sample, by adjusting screw rod through screwing in after the shoulder hole of backing plate and pass gear
Plate, backing plate is fixed on the outside of accurate adjustment sliding block, baffle plate is fixed on sole-plate.
Compared with prior art, the positive effect of the present invention is：Rubber tensile scrag test folder can adjust using this
Tool, by the sliding block being connected with two dovetail grooves on sole-plate, mobile sliding block is pulled to enter to alignment pin by stayed mast
Row coarse positioning, then sliding block is accurately adjusted by adjusting screw rod again, to ensure quickly and accurately to draw rubber parts sample
1.5 times of original distances are reached, to obtain accurate deflection.This fixture can not only be accurately obtained the data (rubber of experiment
Glue deflection), moreover it is possible to improve the locating speed of test clamping；Simultaneously multiple adjustable rubber tensiles can be placed in chamber forever
Long deformation test fixture and sample, greatly improve the utilization rate of testing equipment, are both effectively improved test efficiency, also save
About substantial amounts of experimentation cost.
The knot that this regulation rubber tensile scrag test fixture is not only simple in structure beneficial to clamping and obtained to experiment
Fruit is accurate, and the invention is effectively rotated both clockwise and counterclockwise band movable slider using screw thread and moved left and right and sliding block and track plates or so
Movement simultaneously can prevent the dovetail groove of front and rear bob from coordinating, and reach the effect of accurate adjustment rubber tensile length；Also exist in addition
Anti-slop serrations are added on cover plate and sliding block, rubbery sample are effectively prevented after the stretch after adding anti-slop serrations, due to rubber
Plastic deformation caused by screen resilience, rubbery sample is slided between cover plate and sliding block, so preferable guarantee test obtains data
It is true and reliable.The invention reduces the error in experiment, so as to ensure that the quality of product.
Brief description of the drawings
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein：
Fig. 1 is the structural representation of rubber parts sample to be tensioned；
Fig. 2 is the front view of this adjustable rubber tensile scrag test fixture；
Fig. 3 is the top view of this adjustable rubber tensile scrag test fixture；
Fig. 4 is the connected mode of sole-plate and sliding block.
Embodiment
A kind of adjustable rubber tensile scrag test fixture, as shown in Figures 2 and 3, including：Sole-plate 1, positioning
Pin 2, mobile sliding block (coarse adjustment sliding block) 3, baffle plate 4, cross key grooved screw 5, handle 6, backing plate 7, band tooth cover plate 8, adjusting screw rod 9,
Mobile sliding block (accurate adjustment sliding block) 10, soket head cap screw 11, stayed mast 12 etc., wherein：
A logical dovetail groove 13 is milled with sole-plate 1, the swallow set with accurate adjustment sliding block 10 and the bottom surface of coarse adjustment sliding block 3
Tailstock coordinate (as shown in Figure 4), enable accurate adjustment sliding block 10 and coarse adjustment sliding block 3 on sole-plate slidably；In accurate adjustment sliding block
10 and coarse adjustment sliding block 3 on cover plate 8 is provided with by soket head cap screw 11, for clamping rubber parts sample；In order to more firm press from both sides
Sample is held, not fallen off when pulling sliding block, anti-slop serrations can be set on the contact surface of cover plate and sliding block.
Screwed in after adjusting screw rod 9 is passed through into the shoulder hole of backing plate 7 and pass baffle plate 4, be then screwed backing plate 7
The outside of accurate adjustment sliding block 10, one handle 6 is fixed with cross key grooved screw 5 in the end of adjusting screw rod, the baffle plate 4 is consolidated with screw
It is scheduled on sole-plate 1, to ensure when turning handle, by adjusting screw rod accurate adjustment sliding block 10 can be driven to move left and right.
After by rubber parts sample holder on accurate adjustment sliding block 10 and coarse adjustment sliding block 3, slided on sole-plate 1, away from coarse adjustment
The alignment pin 2 coordinated with the interporal lacuna on sole-plate is provided with (being left side in Fig. 2 and Fig. 3) 40 to 42mm of the inner side of block 3；It
It is due to that sample is usually 82 to 85mm so being 40 to 42mm, the distance of 1.5 times of stretching, then needs coarse adjustment sliding block 3 to move 40
To 42mm.
Stayed mast 12 is set in the both sides of coarse adjustment sliding block 3, and motive force bar 12 drives coarse adjustment sliding block 3 (to be positioned to specified location
The outside of pin 2) when, pushing up alignment pin 2 makes coarse adjustment sliding block 3 be fixed on the outside of alignment pin.
Operation principle：The sample both ends for finishing line are press respectively against two cunnings by soket head cap screw 11 with band tooth cover plate 8
Block is locked on (3 and 10), then pulls stayed mast 12 coarse adjustment sliding block 3 is moved at pin hole, and it is fixed to push up alignment pin 2
Position, the handle 6 in regulating bolt 9 is then turned with hand, moves left and right accurate adjustment sliding block 10, reaches two for accurately adjusting and finishing
Line takes out alignment pin 2 into original 1.5 times of distance after having tested, you can returns to original position, its deformation can be measured by taking out sample
Rate.
