The back wall damage phenomenon and the relation of cavity size occurred when Morphology Evolution rule and Laser Processing cavity part, generally requires
It is studied by Physical Experiment.
When probing into the Morphology Evolution rule of micropore shaping, since micropore size is only between 0.2~1mm, if in material table
At face punch, to observe the forming process of micropore then needs diametrically to split micropore with wire cutting method, then with microscope into
Row observation, and substantial amounts of heat can be generated during wire cutting, cell morphology is damaged, influences experimental result.Using in material
Being punched on the splicing gap of material then can be to avoid this problem, but the tightness degree spliced at gap can also cause experimental result
It influences, if the fitting of material stitching portion is not close, laser will be radiated at material internal when starting drilling by gap, cause to burn
Depth is lost higher than normal value, therefore in laser drilling process, ensureing that the splicing gap of two panels test specimen fits closely just becomes to pass
It is important；, it is necessary to change the size of cavity, usually on two panels test specimen one when probing into the relation of back wall damage phenomenon and cavity size
Once be placed in parallel to simulate cavity part, thus how easily to change in laser drilling process between two panels test specimen away from
From being matter of utmost importance that the experiment must solve.And lack at present a set of economical and practical, conveniently adjusted test specimen clamping height and
The fixture of clamping force.
The content of the invention
The purpose of this utility model is to provide patterns easy to operate, easy to use, being shaped convenient for experimental exploring micropore
A kind of flexible jig for laser drill experiment of size relationship between Evolution and back wall damage and cavity.
The utility model is equipped with pedestal, hold-down mechanism, baffle, upper pallet, lower pallet, tabletting, gasket, stay bolt and spiral shell
It is female；6 root long bolts are fixed on by corresponding countersunk head threaded hole on pedestal on pedestal, and the lower pallet is equipped with 4 through holes,
Through 4 root long bolts in 4 through holes, and pass through the nut on stay bolt and adjust height, the upper pallet is equipped with and 6 root longs
Corresponding 6 through holes of bolt, 6 through holes pass through the nut on stay bolt and adjust height through 6 root long bolts；In pop-up
It sets above plate and is sleeved on there are two tabletting on two intermediate root long bolts, baffle and hold-down mechanism, gear are equipped in the both sides of upper pallet
Plate is connected by the bolt of bottom with pedestal, and hold-down mechanism is bolted on pedestal；Gasket is located at upper pallet and subiculum
Between the lower surface of plate and nut, with scattered nut to the pressure of upper pallet and lower pallet, make upper pallet and lower pallet stress equal
It is even.
The hold-down mechanism includes a pressing plate, two smooth cylindrical slideways, a rooted tooth bar, two bearings and two
A bearing；Two of which bearing is bolted on pedestal, and two guide rails and a rooted tooth bar are connected between two bearings,
A bearing is respectively and fixedly provided in each bearing, tooth bar one end is inserted in bearing, and the tooth bar other end passes through bearing, makes tooth bar can be with
It rotates freely；Pressing plate is sleeved on by the through hole of lower part in guide rail and tooth bar, can be realized along rail axis with the rotation of tooth bar
The movement in direction.
The upper pallet of the utility model and levelness of lower pallet, height and the distance between upper pallet and lower pallet are all
It can be adjusted by the nut on stay bolt.It is drilled when using laser drilling on material splicing gap with probing into micropore shaping
During law, by adjusting nut upper pallet is made to be in suitable height, screw upper lower nut after it is in horizontal, in fixation
Two pieces of experiment test specimens are then positioned on upper pallet, push down test specimen with tabletting, the nut in tabletting is applied centainly by supporting plate
Pretightning force rotates tooth bar, and pressing plate is made to compress test specimen, after pressing force reaches expected requirement, then screws the nut in tabletting, completes
Test specimen clamping；When the damage of experimental study back wall and the relation of cavity size, tabletting is removed, is respectively put on upper pallet and lower pallet
A piece of test specimen, you can punched, when the test specimen on upper pallet is punched by laser, laser can pass through the circular hole on upper pallet
The surface of test piece being irradiated on lower pallet.The distance between two panels test specimen can be changed by adjusting nut, reach experiment purpose.
The utility model has the following advantages：
1) part for forming fixture is attached by screw bolt and nut, compact-sized, easy for assemble or unload, convenient for dimension
It repaiies and carries.
2) fixture design is reasonable, and test specimen clamping is simple, can meet the needs of laser drill experiment, improve conventional efficient.
