The clamp is safe and reliable to mount, simple to demount and convenient to assemble, angles of parts in the clamp are set to enable stressed direction to accurately ensure fiber direction of a testing sample. The clamp has a rigid connection function and meets the quality requirements on the rotors of the airplane products. The objectives of safety and reliability of the glass fiber product in the rotors are achieved, and requirements on integral quality of rotor products are met. The structure is reliable in positioning, firm in clamping and simple and convenient to operate.

Description

A kind of without latitude band compression cutting method
Technical field
The invention belongs to detection technique, relate to a kind of without latitude band compression cutting method.
Background technology
Aircraft product is during fabrication, it is necessary to the product manufactured carries out detection test, and owing to aircraft product rotor is that composite is fabricated by, composite is to be formed by combinations of materials such as carbon fiber, glass fibre, rigid foam, glue, and interior tissue cannot detect.So needing to adopt single product to detect test one by one.So need a set of special fixture.Existing glass fibre sample single product detection vice is instrument, the size of the uncontrollable power of vice, and operation inconvenience impact is normal to be produced.The described phenomenon that cannot detect test after aircraft product rotor manufactures, it is achieved single product is testing goal one by one, meets product quality requirement.
Summary of the invention
For overcoming the problems referred to above, the present invention provides a kind of and compresses cutting method without latitude band, to meet product quality requirement, experimental phenomena cannot be detected after avoiding product manufacturing good, realize single product testing goal one by one, in order to process qualified products, meet product quality requirement.
The technical solution of the present invention is:
1) fixture is prepared
Fixture is made up of clamp body, briquetting and locating piece, and clamp body center has elongated slot, and the upper surface of locating piece has V-shaped groove, the opening angle of V-shaped groove is 80-90 degree, lower surface has groove, and the degree of depth of groove is the 3/7 of specimen length, and the width of groove is the width of sample；Briquetting upper surface is plane, and lower surface has V-shaped groove, and the opening angle of V-shaped groove is 110-120 degree, and the width of clamp body central slot is corresponding with the exterior surface dimension of the outer surface of briquetting and locating piece；
2) sample is installed
First one of them briquetting is put into the elongated slot of clamp body, briquetting is with V-shaped groove one side upwards, then, put into locating piece (3), the V-shaped groove that the V-shaped groove one of locating piece faces down with briquetting contacts, and is put into by sample in the groove of locating piece, then another locating piece is loaded clamp body, make sample be placed in the groove of locating piece, then briquetting loaded in clamp body and make its V groove contact with the V-shaped groove of locating piece；
3) compression shear
Fixture is placed on puller system, is compressed shearing to sample with 8mm/min and 8 millimeters of speed per minute by handling puller system.
The present invention has the advantage that and beneficial effect
The present invention adopts Split Positioning structure, can effectively contact with product full pattern, by designing a kind of special fixture, puller system is utilized to carry out the compression test after without latitude band and glass fiber product curing molding, solve aircraft product rotor manufacture good after interior tissue cannot test problems, product quality requirement is met after guaranteeing rotor molding, fixture is installed safe and reliable, handling method is simple, it is easy to assemble, in fixture, the angle of each part is in order to the direction of stress can accurately ensure the machine direction of test sample, fixture has the function that is rigidly connected, meet aircraft product rotor prescription.Solving the purpose that glass fiber product is safe and reliable in rotor, meet the requirement of rotor product total quality, this structure location is reliable, and it is firm to clamp, simple to operation.
Accompanying drawing explanation
Fig. 1 is the signal of present configuration schematic diagram.
Detailed description of the invention
Below the present invention is described in further details.
Carry out with product orientation before, first one of them briquetting 2 and one of them locating piece 3 are loaded in clamp body 1 and realize positioning function, then product sample is put in fixture, again another locating piece 3 is loaded clamp body 1, then another briquetting 2 is loaded clamp body 1, realize compression shear product effect by the briquetting 2 being pressed downward against above.
The specific implementation process of a kind of compression shearing clamp of band without latitude of the present invention is: be placed on puller system by fixture, then one of them briquetting 2 and one of them locating piece 3 being loaded loads in clamp body 1 in clamp body 1, again by sample 4, then again another locating piece 3 is loaded in clamp body 1, finally again another briquetting 2 is loaded in clamp body 1, realize without latitude band compression shear sample effect by handling puller system.
Embodiment
Specimen shape is cuboid, long X width X high size is 25X7X10, longitudinally have two elongated slots, material is glass fiber compound material, and locating piece 3 first loads the bottom of clamp body 1, reinstalls briquetting 2, then, sample is put into and is placed on briquetting 2, then put locating piece 3 and briquetting 2 successively, realize without latitude band compression shear sample effect by handling puller system.
