Abstract
The invention discloses a bending test clamp capable of measuring a bending angle. The bending test clamp comprises a supporting seat and supporting rollers, and further comprises an angle measurement device, wherein the angle measurement device is composed of two pointers, an angle ruler and two guide rods; the two pointers and the angle ruler are fixedly connected to form a whole body by rotary supporting points; the pointers can rotate around the rotary supporting points; one pointer and the angle ruler are relatively fixed; a guide groove is formed in the middle of each pointer; the other ends of the two pointers respectively penetrate through the guide grooves through screws to be mounted on the supporting rollers; the two guide rods are fixedly mounted on the guide grooves of the pointers. When the bending test clamp utilizes a bending sample to generate bending, the guide rods of the pointers are pushed to move so that the two pointers rotate around the rotary supporting points; the rotary included angle between the two pointers is the bending angle of a test sample, and the bending angle value can be directly read by the angle ruler.
Description
Technical field
The present invention relates to a kind of material property pick-up unit, particularly a kind of bending test fixture of measuring bending angle.
Background technology
Bending test is the test of the mechanical characteristic while measuring metal material Bending load, is one of basic skills of mechanical property of materials test, and material bending angle is an important indicator of material property.In the time of test Metal Material Welding performance, bending angle when crackle appears in weld seam when bending to welded specimen is measured, and often needs the sample after bending to take off especially, and then use angle survey instrument is measured angle of bend, makes bending test efficiency lower.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of simple in structure, the bending test fixture that can directly measure the bending angle of sample.
For solving the problems of the technologies described above, the present invention has adopted a kind of bending test fixture of measuring bending angle, comprise supporting seat, a roller, also comprise an angle measurement unit, described angle measurement unit is made up of two pointers, bevel protractor and two guide rods, it is integral that described two pointers and bevel protractor are fixedly connected with by pivot point, and described pointer can rotate around pivot point, and wherein a pointer is relative with bevel protractor position fixing; In the middle of pointer, be provided with guide groove, two pointer other ends pass guide groove by screw respectively and are arranged on a roller, and two guide rods are fixedly mounted on the guide groove of pointer.
The beneficial effect that the present invention has: the guide rod motion of push pointer when this bending test fixture utilizes bend specimen to produce bending, two pointers are rotated around pivot point, now the rotation angle of two pointers is the bending angle of sample, then can directly read angle of bend value by bevel protractor.
Accompanying drawing explanation
Fig. 1 is front view of the present invention;
Fig. 2 is vertical view of the present invention.
In figure: 1, supporting seat; 2, prop up roller; 3, pointer; 4, bevel protractor; 5, guide groove; 6, guide rod; 7, pivot point.
Embodiment
As shown in the figure, for a kind of bending test fixture of measuring bending angle, comprise supporting seat 1, a roller 2, also comprise an angle measurement unit, angle measurement unit is made up of two pointers 3, bevel protractor 4 and two guide rods 6, it is integral that two pointers 3 and bevel protractor 4 are fixedly connected with by pivot point 7, and pointer 3 can rotate around pivot point 7, and wherein a pointer 3 is relative fixing with bevel protractor 4 positions; In the middle of pointer 3, be provided with 5, two pointer 3 other ends of guide groove and pass guide groove 5 by screw respectively and be arranged on and prop up on roller 2, two guide rods 6 are fixedly mounted on the guide groove 5 of pointer 3.
While using this bending test fixture to test, first set the position of a roller 2, the guide groove 5 then angle measurement unit being passed on pointer 3 by screw is arranged on a roller 2, and the pointer 3 after installation can rotate around screw.When test, adjust the position of guide rod 6, now two guide rods 6 contact with bend specimen both sides respectively, in the time that sample bends, sample moves downward, and promotes guide rod 6 simultaneously and moves down, under the effect of guide rod 6, pointer 3 relatively rotates, until test stops, now the angle of bend of sample equates with pointer 3 angles.Because a pointer 3 wherein bonds together with bevel protractor 4, position is relatively fixing, and another pointer 3 relative angle chis 4 rotate, and the numerical value of reading pointer 3 angles on bevel protractor 4, is sample bending angle numerical value.
