Description
Technical field
The utility model belongs to testing machine manufacturing technology field, and in particular to a kind of spring buffer Compression and Expansion test clamp
Tool.
Background technology
Often met in mechanical test and testpieces be first stretched to certain force, after unloading again reverse compression to some power
It is worth, then removal test force（Test force is zero）, while the situation of record such as lower curve.Sometimes testpieces is in above-mentioned loading and unloads
The power of load process and deformation are all very small, and process of the test middle cross beam translational speed must be very low, otherwise test force can be caused to lose
Control is gone, such case requires all very high to the mechanical structure and control performance of testing machine, and test period is long.
Utility model content
For drawbacks described above present in prior art, a kind of control accuracy that the utility model provides test force is high,
The more accurate spring buffer Compression and Expansion test fixture of result of the test.
Utility model is achieved through the following technical solutions：A kind of spring buffer Compression and Expansion test fixture, including
Joint pipe sleeve, transmission rod and end cap, described joint pipe sleeve are fixedly installed in the downside of moving beam, joint pipe sleeve and are provided with
Endoporus, transmission rod is slidably supported in joint pipe sleeve endoporus and closed with end cap, and described endoporus is shoulder hole, shoulder hole bottom
Aperture be more than the aperture on top, flange is provided with the middle part of described transmission rod, flange is located at joint pipe sleeve shoulder hole bottom,
The top of joint pipe sleeve shoulder hole is stretched on the top of transmission rod, and the both sides up and down of flange are respectively arranged with spring one and spring two,
The other end of spring one is pressed on the end face of joint pipe sleeve shoulder hole, and the other end of spring two is pressed on end cap.
Further, the lower end of described transmission rod is also fixedly connected with gripping sleeve.
The spring buffer Compression and Expansion test fixture that the utility model is related to, can substantially reduce the requirement to testing machine,
And test efficiency is improved, improve the control accuracy of test force, it is ensured that the accuracy of result of the test.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 be the utility model lock-screw A-A to structural representation；
In figure, 1. sensors, 2. moving beams, 3. joint pipe sleeves, 4. shoulder holes, 5. springs one, 6. transmission rods, 7. is convex
Edge, 8 springs two, 9.. end caps, 10. gripping sleeves, 11. lock-screws.
Embodiment
In order that the technical solution of the utility model can more clearly show, with reference to the accompanying drawings and examples to this
Utility model is described further.
A kind of spring buffer Compression and Expansion test fixture, including moving beam 2, joint pipe sleeve 3, transmission rod 6 and end cap 9,
Described joint pipe sleeve 3 is fixedly installed on the downside of moving beam 2, and transmission rod 6 is slidably supported in joint pipe sleeve 3 and uses end cap
9 closings, joint pipe sleeve 3 is internally provided with shoulder hole 4, and the aperture of the bottom of shoulder hole 4 is more than the aperture on top, described power transmission
The middle part of bar 6 is provided with flange 7, and flange 7 is located at the bottom of joint pipe sleeve shoulder hole 4, and joint pipe sleeve rank is stretched on the top of transmission rod 6
The top in terraced hole 4, the both sides up and down of flange 7 are respectively arranged with spring 1 and spring 28, the other end of spring 1 and joint pipe sleeve
The ladder of shoulder hole 4 is connected, and the other end of spring 28 is connected with end cap, and the present apparatus is by being arranged at transmission rod flange both sides
The pretightning force transmission test force of spring 1 and spring 2.
The lower end of described transmission rod 6 is also fixedly connected with gripping sleeve 10, and transmission rod 6 is fastened by gripping sleeve 10 and sample
Together.The bottom of gripping sleeve 10 is provided with lock-screw 11.
The top of described moving beam 2 is additionally provided with sensor 1, the position for detecting moving beam 2.
The position of moving beam 2 is first adjusted during experiment to be made on the transmission rod 6 of 10 sets of loading devices below of gripping sleeve, Ran Housuo
Tight lock-screw 11, transmission rod 6 starts acting, and this structural beams are moving up and down in testpieces stretching and compression process,
Be not in gap, test force is all controllable in whole process of the test.
The effect of two springs：
1）When crossbeam operation downwards is to experiment compression：Spring 1 first by compression, prevent that the power on testpieces is unexpected on
Rise, it is out of hand.
2）When crossbeam is run up to experiment compression：Spring 2 first by compression, prevent that the power on testpieces is unexpected on
Rise, it is out of hand.
