The accompanying drawing explanation
Fig. 1 is the structural representation of traditional bolt tension force test fixture.
Fig. 2 is the structural representation of bolt tension force test fixture of the present invention.
In accompanying drawing, the implication of mark is as follows:
1: jig frame; 2: upper handle; 3: clamping plate; 4: clamp connecting rod; 5: sidewall; 6:U type breach; 7: bayonet socket: 8: gag lever post.
Embodiment
Below in conjunction with Figure of description, the present invention is further illustrated.
As shown in Figure 2, bolt tension force test fixture of the present invention, compare to traditional bolt tension force test fixture of Fig. 1, upper handle 2 is extended to jig frame 1 inside, and be provided with for placing the U-shaped breach of bolt to be tested in upper handle 2 bottoms, easy to use, good fixing effect, concrete structure is as follows, comprise jig frame 1, jig frame 1 is fixed on test table, jig frame 1 top is provided with handle 2, upper handle 2 is cylindrical shape, extend in the cavity of jig frame 1, the bottom of upper handle 2 is provided with the U-shaped breach 6 for clamping bolt to be tested, by top, the diameter to bottom increases upper handle 2 gradually, the twice that base diameter is top diameter, in clamping process, U-shaped breach 6 can be afterburning gradually, reinforce bolt to be tested, and the respectively inside side in the breach end of U-shaped breach 6 extends, be formed for blocking the bayonet socket 7 of bolt to be tested, in the time of can effectively being placed on tensile test, bolt to be tested breaks away from U-shaped breach, and can not produce inclination, guarantee the degree of accuracy of test, the side that the inboard of jig frame 1 is positioned at handle 2 also is provided with a left side, the two clamping plates 3 of right symmetry, each clamping plate 3 run through the sidewall 5 of jig frame 1 by the clamping connecting rod 4 of respective side, clamp the bottom that connecting rod 4 rotations promote the upper handle 2 of clamping plate 3 compression of connection, the to be tested bolt of fixed placement in U-shaped breach 6, the inwall of each clamping plate 3 is set to anti-skidding lines, the upper handle 2 of anti-skidding lines compression cylindrical shape is arranged in the part of jig frame 1, due to much larger than the face of traditional independent hold-down bolt in the plane that contact is arranged, just can not produce tilt phenomenon, guarantee the accuracy of tensile test,
