Description
Technical field
The invention belongs to test equipment technical field, and in particular to a kind of nano-cellulose film stretching clamp.
Background technology
Nano-cellulose film and its laminated film are a kind of new membrane materials and composite, are dried by suction filtration, molding
The dry nano-cellulose film for obtaining or nano-cellulose film and macromolecular material are combined the laminated film for obtaining have intensity it is high,
The performance that thickness is small, surface is smooth.In recent years, with the development of science and technology, increasing field needs high intensity, surface smooth
Nano-cellulose membrane material and its composite, nano-cellulose with increasing macromolecular material, Graphene material
Material etc. prepares composite film material.
The nano-cellulose film obtained using suction filtration, molding drying, generally first carries out suction filtration, then by nanofiber solution
Wet nano-cellulose thin slice is clipped in the nano-cellulose film thickness for drying and shaping being carried out between glass plate or wire netting, being obtained
It is smooth compared with small, surface and intensity is big.
Nano-cellulose film is sample preparation, and when the sample of preparation carries out tension test, overall length is in 3~5cm
Between, because sample is shorter, when sample is filled, also more it is difficult, except the edge of de-clamping, sample span is small, existing stretching
Fixture is difficult to fill sample.
When tension test is carried out, existing fixture can not often be held fixedly nanofiber in use
Plain film, sample is easily slipped, and often occurs not breaking and causing the phenomenon of experiment termination due to slipping, so that cannot be for nanometer
Cellophane carries out tension test.
The content of the invention
Goal of the invention：It is thin it is an object of the invention to provide a kind of nano-cellulose for the deficiencies in the prior art
Film stretching clamp, mechanical test, particularly surface smoother, thickness are carried out to nano-cellulose film and its composite
Thin slice less than 150 microns is clamped.
Technical scheme：In order to realize foregoing invention purpose, the technical solution adopted by the present invention is：
A kind of nano-cellulose film stretching clamp, including the upper fixture that is used in conjunction with each other and lower clamp；Described upper fixture
Including top connection, upper locking nut, upper specific and the first hold assembly, top connection is specifically connected with upper, and is set in top connection
Upper locking nut, the first hold assembly is located at particularly；Lower clamp includes lower contact, lower locking nut, lower specific and second
Hold assembly, lower contact is specifically connected with lower, and locking nut is set in lower contact, and the second hold assembly is located at lower specific
On.
The first described hold assembly be installed in upper two pieces of grip blocks particularly, respectively go forward grip block and it is upper after
Grip block, goes forward grip block and upper rear grip block adjusts relative position by short screw.
Ripple is set on the described clamping face gone forward between grip block and upper rear grip block.
The second described hold assembly is two pieces of grip blocks under particularly, respectively descend front clamp plate and it is lower after
Grip block, lower front clamp plate and lower rear grip block adjust relative position by long bolt.
Ripple is set on clamping face between described lower front clamp plate and lower rear grip block.
When using, described top connection is connected with equipment crossbeam, and described lower contact is arranged on clamping fixture seat.
Beneficial effect：Compared with prior art, nano-cellulose film stretching clamp of the invention, in upper fixture with
Fixture is respectively adopted short screw and long bolt structure, is interfered when can so avoid fixture from being close to, convenient clamping, particularly
The clamping of short sample.Meanwhile, the folder sample position of upper and lower clamp body uses corrugated jaw, and clamping is reliable, and can guarantee that breakpoint is good
It is good.It is applicable the extension test experiment of small sample.It is using scope：Maximum test force：200N；Gripping width：≤10mm；Clamping is thick
Degree：≤3mm.

Specific embodiment
With reference to specific accompanying drawing, the present invention is described further.
As Figure 1-4, nano-cellulose film stretching clamp of the invention, including structure identical upper fixture 1 is with
2 two parts of fixture, upper fixture 1 and lower clamp 2 are used in conjunction with each other.Wherein, upper fixture 1 includes top connection 11, upper locking screw
Female 12, upper specific 13 and first hold assembly, top connection 11 is connected with upper specific 13, and sets upper locking nut in top connection 11
12, the first hold assembly is located on specific 13；First hold assembly is two pieces of grip blocks on upper specific 13, respectively
It is grip block 6 and the upper rear grip block 7 of going forward, go forward grip block 6 and upper rear grip block 7 adjust relative position by short screw 4,
Go forward to set ripple 8 on the clamping face between grip block 6 and upper rear grip block 7.
Equally, lower clamp includes lower contact 21, lower locking nut 22, lower specific 23 and second hold assembly, lower contact 21
It is connected with lower specific 23, and locking nut 22 is set in lower contact 21, the second hold assembly is located on lower specific 23；Second folder
It is two pieces of grip blocks on lower specific 23 to hold part, respectively descends front clamp plate 9 and lower rear grip block 10, lower front clamp
Plate 9 and lower rear grip block 10 adjust relative position, the folder between lower front clamp plate 9 and lower rear grip block 10 by long bolt 5
Hold and set on face ripple 8.
Nano-cellulose film stretching clamp of the invention, short screw 4 and length are respectively adopted in upper fixture 1 and lower clamp 2
The structure of screw rod 5, interferes when can so avoid fixture from being close to, convenient clamping, the clamping of particularly short sample.Meanwhile, on
The folder sample position of lower clamp body（Jaw）Using corrugated jaw, clamping is reliable, and can guarantee that breakpoint is good, effectively overcomes examination
The phenomenon that sample skids.
Upper fixture, when in use, is first inserted equipment crossbeam cross joint by nano-cellulose film stretching clamp of the invention
In head, latch is inserted, then lock upper locking nut upwards.Then lower clamp is attached on grip of testing machine seat, is plugged slotting
Pin, then locks downwards lower locking nut.Moving beam adjusts the distance between upper and lower two fixture；Opened by short screw long
The jaw of upper lower clamp, enables sample 3 to put into jaw；Sample centering is clamped with upper fixture first, then moving beam
Sample is entered in the jaw of lower clamp, then clamp lower clamp；Such as the gauge length of sample is required, it is necessary to first measure upper lower clamp
Between jaw position, then set in testing program and return car, set gauge length during convenient experiment next time.
Nano-cellulose film stretching clamp of the invention, is applicable the extension test experiment of small sample.It is using scope：Most
Big test force：200N；Gripping width：≤10mm；Clamping thickness：≤3mm.
If laboratory or surrounding enviroment have super quantity dust, corrosive fumes or harmful substance etc., it is necessary to the present invention
Nano-cellulose film stretching clamp take safeguard measure.Molybdenum bisuphide lubrication can be smeared to having in fixture at relative motion
Fat.If fixture is relatively in unused state for a long time, fixture is pulled down from testing machine, preservation is wrapped with oilpaper.
