Detailed Description

The technical solution of the present invention will be further explained with reference to the following embodiments and the accompanying drawings.

Referring to fig. 1 to 3, the present embodiment provides a clamping device for a metal pin shear test, which includes a base 1, and a first pipe hole 2 and a second pipe hole 3 opened in the base 1.

Referring to fig. 3, the first pipe hole 2 and the second pipe hole 3 are perpendicular to and communicate with each other. The axis of the first pipe hole 2 extends in the vertical direction, and the axis of the second pipe hole 3 extends in the front-rear direction.

In the present embodiment, the first pipe hole 2 penetrates the base 1 in the direction of its axis (i.e., the up-down direction in fig. 3); the second pipe hole 3 penetrates the base 1 in the direction of its axis (i.e., the front-rear direction in fig. 3).

The clamping device for the metal pin shearing test further comprises a bearing shaft 4 and a third pipe hole 5, wherein the bearing shaft 4 can penetrate through the first pipe hole 2 and can move along the length extending direction of the clamping device, and the third pipe hole 5 is formed in the bearing shaft 4. The pressure bearing shaft 4 and the first pipe hole 2 are parallel to each other.

The pressure bearing shaft 4 is in clearance fit with the first pipe hole 2, and the clearance between the two is not more than 0.15mm in the embodiment.

Referring to fig. 2, the third pipe hole 5 penetrates the backing shaft 4 in its own axial direction (i.e., front-rear direction), and the axial direction of the third pipe hole 5 extends in the radial direction of the backing shaft 4.

The third pipe hole 5 and the second pipe hole 3 are parallel to each other and both are used for sleeving the metal pin shaft.

When the metal pin shaft is simultaneously arranged in the second pipe hole 3 and the third pipe hole 5 in a penetrating way, the second pipe hole 3 and the third pipe hole 5 are coaxially arranged. In the present embodiment, the second pipe hole 3 and the third pipe hole 5 have the same diameter, and are slightly larger than the diameter of the metal pin. When the metal pin shaft is long enough, two ends of the metal pin shaft can respectively penetrate through two ends of the second pipe hole 3 and penetrate through the third pipe hole 5 to carry out a double-sided shearing test; when the metal pin shafts are short, the two metal pin shafts penetrate through the two ends of the second pipe hole 3 respectively and enter the third pipe hole 5 of the pressure bearing shaft 4 simultaneously, and two single-side shearing replaces a double-side shearing test.

When the metal pin shaft penetrates through the second pipe hole 3 and the third pipe hole 5, the upper end of the pressure bearing shaft 4 extends out of the base 1 and is used for bearing pressure, and the lower end of the pressure bearing shaft 4 is located in the base 1. The gap with a certain length is arranged between the lower end of the bearing shaft and the bottom surface of the base 1, and through the arrangement, the bearing equipment below can be prevented from being instantaneously damaged by bearing pressure when the metal pin shaft is cut off in a shear test, so that the safety coefficient of the shear test is increased.

Through set up first tube hole 2 and second tube hole 3 on base 1, the bearing shaft 4 that will be equipped with third tube hole 5 again penetrates first tube hole 2, penetrates second tube hole 3 and third tube hole 5 with metal pin axle simultaneously in, through applying axial pressure to bearing shaft 4 to carry out shear test to metal pin axle, the device simple structure, the operation degree of difficulty is lower relatively.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
