Summary of the invention
The object of the invention is the deficiency overcoming prior art existence, bolt tension test fixture provided by the invention, upper handle is extended to jig frame inside, and the U-shaped breach be provided with at the top of upper handle for clamping bolt, the clamping plate of both sides compress the part being positioned at jig frame of upper handle, thus clamp the bolt to be tested in U-shaped breach, good fixing effect, easy to use, measuring accuracy is high, has a good application prospect.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of bolt tension test fixture, comprise jig frame, described jig frame is fixed on test table, it is characterized in that: described jig frame top is provided with handle, described upper handle is cylindrical shape, extend in the cavity of jig frame, the bottom of described upper handle is provided with the U-shaped breach for clamping bolt to be tested, the side that the inner side of described jig frame is positioned at handle is also provided with a left side, the two clamping plates of right symmetry, each clamping plate run through the sidewall of jig frame by the clamping connecting rod of respective side, the clamping plate that described clamping connecting rod rotation forces connects compress the bottom of upper handle, the to be tested bolt of fixed placement in U-shaped breach.
Aforesaid a kind of bolt tension test fixture, is characterized in that: described upper handle is increased gradually by the diameter of top-to-bottom, and base diameter is the twice of top diameter.
Aforesaid a kind of bolt tension test fixture, is characterized in that: the breach end limit prolongation to the inside respectively of described U-shaped breach, forms the bayonet socket for blocking bolt to be tested.
Aforesaid a kind of bolt tension test fixture, is characterized in that: the inwall of each clamping plate is set to anti-skidding lines.
Aforesaid a kind of bolt tension test fixture, is characterized in that: the sidewall that each clamping connecting rod both sides are positioned at jig frame is also fixed with gag lever post.
The invention has the beneficial effects as follows: bolt tension test fixture provided by the invention, upper handle is extended to jig frame inside, and the U-shaped breach be provided with at the top of upper handle for clamping bolt, the clamping plate of both sides compress the part being positioned at jig frame of upper handle, thus the bolt to be tested clamped in U-shaped breach, good fixing effect, easy to use, measuring accuracy is high, has a good application prospect.
Accompanying drawing explanation
Fig. 1 is the structural representation of traditional bolt tension test fixture.
Fig. 2 is the structural representation of bolt tension test fixture of the present invention.
The implication marked in accompanying drawing is as follows:
1: jig frame; 2: upper handle; 3: clamping plate; 4: clamping 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 test fixture of the present invention, compare to traditional bolt tension test fixture of Fig. 1, upper handle 2 is extended to jig frame 1 inner, and the U-shaped breach be provided with bottom upper handle 2 for placing bolt to be tested, 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, upper handle 2 is increased gradually by the diameter of top-to-bottom, base diameter is the twice of top diameter, in clamping process, U-shaped breach 6 can be afterburning gradually, reinforce bolt to be tested, and the limit prolongation to the inside respectively of the breach end of U-shaped breach 6, form the bayonet socket 7 for blocking bolt to be tested, when effectively can be placed on tensile test, bolt to be tested departs from U-shaped breach, and can not inclination be produced, ensure the degree of accuracy of test, the side that the inner side of jig frame 1 is positioned at handle 2 is also 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, the clamping plate 3 that clamping connecting rod 4 rotation forces connects compress the bottom of upper handle 2, 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, owing to there being much larger than the face of traditional independent hold-down bolt of the plane of contact, tilt phenomenon would not be produced, ensure the accuracy of tensile test,
The sidewall 5 that the both sides of clamping connecting rod 4 are positioned at jig frame 1 is also fixed with gag lever post 8, gag lever post 8 is used for limiting the ultimate range that clamping connecting rod 4 promotes clamping plate 3 advance, the i.e. dynamics that uses of maximum restriction maximum grip bolt, effectively prevent, the dynamics of clamping is too tight, the surface structure of damage bolt.
In sum, bolt tension test fixture of the present invention, extends to jig frame inside by upper handle; and the U-shaped breach be provided with at the top of upper handle for clamping bolt; the clamping plate of both sides compress the part being positioned at jig frame of upper handle, thus clamp the bolt to be tested in U-shaped breach, good fixing effect; effectively can also protect bolt; clamping within reason, the surface structure of damage bolt, easy to use; measuring accuracy is high, has a good application prospect.
More than show and describe ultimate principle of the present invention, principal character and advantage.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
