Abstract
The utility model relates to a tensile compressible double-shear clamp for testing the shearing strength of material, wherein the inner part of a shearing groove is connected with a shearing male die; a circular through-hole and a rectangular through-hole are also formed at the upper part and the lower part of a center line positioned at the lower end of the shearing male die; the upper end of the shearing male die is connected with a tester upper grip tension direction cylinder through screw threads; the lower end of a clamp body is connected with a tester lower grip tension direction cylinder through the screw threads; and the shearing male die can oppositely slide in the shearing groove up and down. The tensile compressible double-shear clamp achieves the technical effects as follows: shearing material can be clamped and demounted conveniently; and the tensile compressible double-shear clamp further has the advantages of small size, simple structure, no slipping and the like.
Description
Technical field
The utility model relates to a kind of double shear anchor clamps of test material shear resistance, relates in particular to a kind of double shear anchor clamps that can press the test material shear resistance that draw.
Background technology
At present; Electronic tension tester is when various materials in tension and compression intensity of test and shear resistance; The used anchor clamps of clamping material only are furnished with circular section bar commonly used and square-section plate grip, and are not equipped with the anchor clamps of test material shear resistance, and the existing shearing anchor clamps machine direction that is put to the test is selected influence; What have can only do tensile shear, and shearing is pressed in can only doing of having.
Summary of the invention
The purpose of the utility model has been to provide a kind of double shear anchor clamps that can press the test material shear resistance that draw; The defective that this test fixture overcomes that present testing machine does not have to be equipped with and existing anchor clamps commonly used can not the test material shear resistance, these anchor clamps adopt groove and punch to slide up and down the double-shear structure, availablely draw or press the test material shear resistance; Be difficult for skidding; Charge and discharge operations is simple and reliable, but diversity materials such as sheared cylinder, cuboid, advantage such as test result is accurate.
The utility model is realized like this; It comprises that the testing machine upper grip pulls to right cylinder, shears punch, shear groove, anchor clamps right part, manhole, rectangular through-hole, testing machine lower chuck pull to right cylinder, anchor clamps left part; It is characterized in that the double-shear anchor clamps are symmetric shape; Have a shear groove in the middle of the clamp body anchor clamps are divided into anchor clamps left part and anchor clamps right part; Have a manhole and rectangular through-hole up and down on the center line of anchor clamps left part middle-end, have a manhole and the rectangular through-hole symmetrical on the center line of anchor clamps right part middle-end up and down, be connected with the shearing punch in the shear groove with the anchor clamps left part; Also have a manhole and rectangular through-hole up and down on the center line of shearing punch lower end; The upper end of shearing punch pulls to right cylinder with the testing machine upper grip that is threaded, and the clamp body lower end pulls to right cylinder with the testing machine lower chuck that is threaded, and shears punch and can in shear groove, slide relatively up and down.
The technique effect of the utility model is: these double-shear anchor clamps have been filled up the defective that existing testing machine is not equipped with test material shear resistance anchor clamps, can shear cylinder material and 15 millimeters cuboid materials of 5 χ, 5 millimeters ~ 15 χ of 5 ~ 15 millimeters of diameters; Adopt groove location punch, shear punch during shearing and can in shear groove, slide relatively up and down, when the anchor clamps upper and lower side with the testing machine that is threaded on lower chuck when pulling to right cylinder; Available stretch is done the shear resistance test of material; When lower chuck pulled to right cylinder on unloading the connection testing machine, the available shear resistance of doing material of pressing to was tested, can be easily with shearing the material clamping and unloading; It is little to have more volume, advantage such as non-slip simple in structure.

Fig. 1 is the structural representation of the utility model.
In the drawings, 1. the testing machine upper grip pulls to right cylinder 2. testing machine upper grip planes 3. and shears punch 4. shear groove 5. anchor clamps right parts 6. right cylinder test specimens 7. manholes 8. cuboid test specimens 9. rectangular through-hole 10. and connect tester base and press to plane 11. and connect the testing machine lower chucks and pull to right cylinder 12. anchor clamps left parts.
Embodiment
As shown in Figure 1; The double-shear anchor clamps are symmetric shape; Have a shear groove (4) in the middle of the clamp body anchor clamps are divided into anchor clamps left part (12) and anchor clamps right part (5); Have a manhole (7) and rectangular through-hole (9) on the center line of anchor clamps left part (12) middle-end up and down; Have a manhole (7) and the rectangular through-hole (9) symmetrical with anchor clamps left part (12) on the center line of anchor clamps right part (5) middle-end up and down, also have a manhole (7) and rectangular through-hole (9) up and down on the center line of shearing punch (3) lower end, the upper end of shearing punch (3) pulls to right cylinder (1) with the testing machine upper grip that is threaded; The clamp body lower end pulls to right cylinder (11) with the testing machine lower chuck that is threaded, and shears punch (3) and can in shear groove (4), slide relatively up and down.During use; To shear punch (3) inserts in the shear groove (4); Manhole (7) or the rectangular through-hole (9) of shearing punch (3) lower end is with after the manhole (7) of anchor clamps left part (12) and anchor clamps right part (5) or rectangular through-hole (9) align; Right cylinder test specimen (6) or cuboid test specimen (8) insertion are passed anchor clamps left part (12) and anchor clamps right part (5); To connect the testing machine upper grip and pull to right cylinder (1) access testing machine upper grip, and connect the testing machine lower chuck and pull to right cylinder (11) access testing machine lower chuck, testing machine is done to stretch and just can be destroyed the material double-shear; To connect the testing machine upper grip pulls to right cylinder (1) and is connected the testing machine lower chuck and pulls to right cylinder (11) and revolve and unload; Connect testing machine seaming chuck plane (2) contact test machine upper grip; Connect tester base and press to plane (10) contact test machine base, testing machine is done and is just pressed to and can destroy the material double-shear.
The principle of work of the utility model is: the double-shear anchor clamps are cut anchor clamps than simple shear and are received force mode more steady, and the utility model double-shear anchor clamps then are the available test material shear resistances of drawing or press, and the double-shear anchor clamps are formed by shearing punch and shear groove; Symmetry has a manhole and rectangular through-hole on anchor clamps left part and anchor clamps right part center line, and this two hole is the fixed position of shearing material, also has a manhole and rectangular through-hole in shearing punch lower end; Can select that hole suitable according to the shape of shearing material, shear punch during shearing and in shear groove, slide up and down, guarantee that shearing punch and shear groove contact gap are very little; Guarantee that really material is a shear failure; Rather than shear and to add fail in bending, after material is cut off, will shear punch and up rise; One root timber material is sheared into three and breaks; It generally is smooth shearing material fracture, because of material is that double-shear is destroyed, and will be when calculating shear resistance with the maximum load of shear failure two times of areas before divided by material damage.
