Description

Metal material tensile test anchor clamps

Technical Field

The application relates to the technical field of mechanical property test and detection of metal materials, in particular to a mechanical property tensile test fixture, which realizes tensile test and detection of mechanical property of metal materials.

Background

The existing metal material tensile test clamp has two main structures. One type is a clamp with two semi-cylindrical barrels in a centering matching structure, the two semi-cylindrical barrels are symmetrical left and right and are connected through a lock catch to form a cylindrical barrel, and a tensile sample is fixed in the cylindrical barrel during a test; this structure mainly relies on manual regulation anchor clamps to press from both sides tight sample, and not only inefficiency still appears pressing from both sides tightly easily, skids or drops the phenomenon such as. The other type is a barrel type opening clamp, U-shaped holes are formed in the bottom and the side face of the barrel, the sample is fixed in the barrel in an open mode, and the structure often shows that the sample bursts or falls off. The test data are inaccurate or invalid due to the conditions, and the test fixture protection device is incomplete and has great potential safety hazard.

Disclosure of Invention

Based on prior art not enough, the utility model aims to provide a metal material tensile test anchor clamps. Under the condition of ensuring reasonable structure and sufficient strength, the invention provides the metal material tensile test clamp with the closed structure, which can realize quick and convenient installation and disassembly of a tensile sample and is provided with a safety protection cover. The scheme of this application does:

the utility model provides a metal material tensile test anchor clamps, includes solid fixed cylinder, safety cover, connecting rod, and gu the fixed cylinder card is in the safety cover, and the connecting rod is fixed at the safety cover top, and the connecting rod is connected with tensile equipment, and test fixture installs in solid fixed cylinder, and the safety cover is rotatory seals test fixture in solid fixed cylinder. The outer side surface of the protective cover is provided with a door-shaped window, the upper part of the protective cover is provided with anti-skid grains, and the outer side surface corresponding to the door-shaped window is provided with a window. Wherein the window is a strip-seam structure, and the door-shaped window is a structure with a big top and a small bottom. A through U-shaped groove is formed in the bottom surface of the fixed cylinder, the test fixture is clamped in the U-shaped groove, the opening direction of the U-shaped groove faces towards the door-shaped window, a step matched with the protective cover is arranged on the bottom edge of the U-shaped groove, and the protective cover can rotate along the step. The protective cover and the fixed cylinder are connected with the connecting rod through a pressing ring and a locking nut.

This application has adopted closed structure, and the tester can be very smooth when loading and unloading the sample install with lift off, though the fluting of anchor clamps solid fixed cylinder bottom is the U type, inside the structure assurance sample of big-end-up is fixed in solid fixed cylinder on the anchor clamps solid fixed cylinder window, can not spurt the solid fixed cylinder of anchor clamps when the sample is broken. The huge energy released in the moment that the metal material sample is broken can cause the metal material or inclusions to burst out, and the safety coefficient of the test is increased by using the clamp protection cover.

Detailed Description

Referring to the attached drawings, the metal material tensile test fixture comprises a fixed cylinder 6, a protective cover 4 and a connecting rod 1, wherein the fixed cylinder 6 is clamped in the protective cover 4, the connecting rod 1 is fixed to the top of the protective cover 4, the connecting rod 1 is connected with tensile equipment, the test fixture is installed in the fixed cylinder 6, and the protective cover 4 rotates to seal the test fixture in the fixed cylinder 6. The outer side surface of the protective cover 4 is provided with a door-shaped window 9, the upper part of the protective cover is provided with anti-skid grains 10, and the outer side surface corresponding to the door-shaped window 9 is provided with a window 11. Wherein the window 11 is a strip-seam structure, and the door-shaped window 9 is a structure with a big top and a small bottom. A fixed cylinder window 5 consistent with the door-shaped window is formed in the side face of the fixed cylinder 6, a through U-shaped groove 8 is formed in the bottom face of the fixed cylinder, the test fixture is clamped in the U-shaped groove 8, the opening direction of the U-shaped groove 8 faces the fixed cylinder window 5, a step 7 matched with the protection cover 4 is arranged on the bottom edge of the U-shaped groove, and the protection cover 4 can rotate along the step 7. The protective cover 4 and the fixed cylinder 6 are connected with the connecting rod 1 through the pressing ring 3 and the locking nut 2.

When a metal material tensile sample is installed, the protective cover 4 is rotated to enable the door-shaped window 9 to be overlapped with the fixed cylinder window hole 5, the tensile sample is placed into the U-shaped groove 8 and clamped into the bottom side of the inner wall of the fixed cylinder window hole 5, and then the protective cover 4 is rotated until the strip seam type window 11 faces a tester. The test procedure is started, the tensile deformation condition of the sample can be observed through the window 11, and the sample after being pulled off is wrapped in the fixed cylinder 6, so that the condition that a person is splashed is avoided.
