Abstract
The utility model discloses a connecting device that fatigue testing machine hydraulic cylinder anchor clamps used. The device comprises a clamping block (1) and a connecting block (2), wherein the clamping block (1) and the connecting block (2) are fixed by threads. Furthermore, the clamping block (1) is provided with a depth positioning block (3) for clamping depth positioning; the connecting block (2) is provided with a threaded hole for mounting a sample; the connecting devices need to be used in pairs; the upper clamp and the lower clamp of the testing machine respectively clamp one connecting device. The device has the advantages of reasonable design, simple structure, safe use, low cost, convenient assembly and disassembly, easy operation and better applicability and practical value.
Description
Technical field
The utility model belongs to the physical test equipment of metal material, relates to fatigue tester cartridge type design of Clamping Apparatus and improvement.
Background technology
For the axial fatigue performance test of metal material, the equipment that uses at present is electo hydraulic servocontrolled fatigue testing machine, electromagentic resonance type fatigue tester mostly.Usually the torture test machine clamp has Wedge gripping, horizontal sliding anchor clamps and cartridge type anchor clamps.The cartridge type anchor clamps have right alignment good, the sample holder surface are not had advantages such as the damage of folder tooth, long service life, on the high-end fatigue tester of import, extensively adopt at present, as using on the high-end fatigue testers such as INSTRON, Zwick, MTS.And its shortcoming is: anchor clamps clamping size of sample narrow range (general range by the mark specification-2mm), need join the anchor clamps of plurality of specifications, to satisfy the requirement of different size specimen test.And the cartridge type clamp-replacing gets up also cumbersome, and is both time-consuming, and effort the more important thing is that the grip of testing machine price is more expensive again, buys the anchor clamps of all size, and cost is higher.
Summary of the invention
The purpose of the utility model is: on the basis that utilizes testing machine cartridge type anchor clamps, through manufacturing and designing the coupling arrangement adaptive with anchor clamps, make it be suitable for multiple size of sample, have good practical values.
The technical scheme that the invention of this reality is adopted:
The coupling arrangement that a kind of fatigue tester hydraulic pressure cartridge type anchor clamps use; This coupling arrangement comprises grip block (1) and contiguous block (2); Grip block (1) is fixedly connected with screw thread with contiguous block (2), the diameter of grip block (1) and anchor clamps coupling, and contiguous block (2) is provided with threaded hole (4) and is used to install sample.
Say that further grip block (1) is provided with depth localization piece (3), depth localization piece (3) designs with grip block (1) one, is used for the location of the anchor clamps clamping degree of depth, and its diameter is greater than the diameter of grip block.
For the ease of better screwing between grip block (1) and the contiguous block (2), contiguous block (2) chamfered edge uses, and the size and the specimen finish size of screw thread are complementary in the contiguous block (2); Size according to specimen finish is changed contiguous block (2).
The utility model has the advantages that: the grip of testing machine that makes full use of limited specification; Through coupling arrangement, make a kind of anchor clamps of specification, the sample of the applicable plurality of specifications of conversion through contiguous block in this coupling arrangement uses; Reduce the purchase of anchor clamps effectively; Reduce cost, save human and material resources and time, improve detection efficiency.
Description of drawings:
Fig. 1 is the structural representation of facing of apparatus of the present invention;
Embodiment
Below in conjunction with accompanying drawing the present invention is done further elaboration: the coupling arrangement that uses like fatigue tester hydraulic pressure cartridge type anchor clamps shown in the drawings comprises grip block 1 and contiguous block 2; Grip block 1 is fixedly connected with contiguous block 2 usefulness screw threads; Grip block 1 is provided with depth localization piece 3, and depth localization piece 3 can limit the clamping degree of depth.Need when coupling arrangement uses to use in pairs, grip block 1 should be screwed with contiguous block 2, screws for the ease of the two, can contiguous block 2 chamfered edges be used.The sample clamping is in the threaded hole 4 of contiguous block 2, and when doing drawingand pressing fatigue, sample should be tightened in the threaded hole 4, and can change contiguous block 2 according to size of sample.As, specimen finish is 16mm, just changes contiguous block 2, the diameter that makes the threaded hole 4 in the contiguous block 2 is 16mm, is 20mm like specimen finish, promptly changes the contiguous block 2 of the threaded hole that has the 20mm diameter.Coupling arrangement uses in pairs, each one up and down of grip of testing machine.
Claims (2)
1. the coupling arrangement that uses of fatigue tester hydraulic pressure cartridge type anchor clamps, it is characterized in that: this coupling arrangement comprises grip block (1) and contiguous block (2), and grip block (1) is fixedly connected with screw thread with contiguous block (2), and contiguous block (2) is provided with threaded hole (4).
2. the coupling arrangement that fatigue tester hydraulic pressure cartridge type anchor clamps according to claim 1 use is characterized in that grip block (1) also is provided with depth localization piece (3).
