Description

Tensile test fixture

Technical Field

The utility model relates to the field of clamps, in particular to a tensile measurement and testing clamp.

Background technique

In mechanical processing, there are often standard measurement bases for various properties of mechanical parts. Among them, for mechanical parts such as rods, there are usually strict standards for their tensile properties because they affect the safety of the final product. At present, when testing the tensile properties, it is usually necessary to clamp the two ends of the rod with a clamp and place it on a tensile testing machine for measurement. When clamping circular rods, existing clamps mostly use pliers to clamp them, but after clamping, it is still easy to cause the rod to loosen and rotate, thereby affecting the accuracy of the measurement operation.

A tensile measurement and testing fixture as shown in Figure 1 includes a base plate 1, a pair of clamping plates 2 of matching shapes are sleeved on both sides of the base plate 1, a rotating shaft 3 is arranged inside the base plate 1, and the rotating shaft 3 is driven to rotate by a motor 31, a pair of screw rods 32 with opposite thread rotation directions are fixed at both ends of the rotating shaft 3, and matching nut seats 33 are arranged on the screw rods 32 on both sides, the nut seats 33 extend out of the base plate 1 and are connected and fixed to the clamping plate 2, an arc-shaped clamping groove 21 is arranged on the inner side of the clamping plate 2, a clamping rod 22 is arranged on the upper end of the clamping groove 21, a sliding rod 23 is fixed on the clamping rod 22, and the sliding rod 23 slides out of the clamping groove 21, the clamping rod 22 is rotatably connected to the adjusting rod 24, and the adjusting rod 24 threads out of the clamping groove 21.

Furthermore, a connecting seat 25 is fixed to the bottom of the clamping plate 2 , the connecting seat 25 is slidably sleeved on the bottom plate 1 , and the nut seat 33 is connected and fixed to the connecting seat 25 .

Furthermore, the bottom surface of the clamping rod 22 is in an arc shape.

Furthermore, an adjusting knob 26 is disposed on the adjusting rod 24 .

The utility model discloses a tensile measuring and testing fixture, which can better clamp rods of different diameters and models, and then test the tensile performance through a tensile testing machine.

Specifically, the clamp can clamp the two ends of the rod body, and then be installed on a tensile testing machine to test the tensile performance. When clamping, the ends of the rod body are placed between the clamping plates 2 on both sides, and then the motor 31 drives the rotating shaft 3 to rotate, so that the screw rods 32 on both sides of the rotating shaft 3 rotate synchronously, and because their rotation directions are opposite, they can drive the screw nut seats 33 thereon to move synchronously towards each other until the rod body is clamped and fixed by the clamping grooves 21 on the clamping plates 2.

Next, by rotating the adjusting knob 26, the adjusting rod 24 is driven to rotate, pushing the clamping rod 22 thereon to press against the upper outer wall of the rod body, thereby clamping and fixing the rod body to ensure its stability during tensile testing.
