Description

Fastener tensile test anchor clamps

Technical Field

The utility model relates to a fastener tensile strength test field, concretely relates to fastener tensile test anchor clamps.

Background

At present, along with the increasing international situation, the requirements of military countries on weapons are higher and higher. With the advent of fifth and sixth generation aircraft, the role of fasteners in aerospace products has become increasingly prominent, placing greater demands on the attachment of engines to aircraft. The performance of the fastener requires high temperature resistance, light weight, high strength, long service life, corrosion resistance, convenient installation and the like.

Aerospace fasteners include primarily bolts, nuts, rivets and other types of fasteners. Due to the fact that installation positions of the fasteners are different, the fasteners with different performance and structural size requirements are produced, for example: single-sided rivets, countersunk screws, large footing rivets, and the like. The materials used for the fasteners mainly include, depending on the location and structure of use: titanium alloy, high temperature alloy, aluminum alloy, high quality structural steel, assembly parts and the like. Due to the fact that the fasteners are various, the tensile test clamp in the test process is various and simple. The fastener tensile test anchor clamps that use in the test process all do not have protective baffle at present, easily take place the phenomenon that test piece fracture popped out test fixture in the test process, lead to test data inaccurate and easily take place to injure people's scheduling incident.

Disclosure of Invention

The utility model aims at solving the above problem and providing a fastener tensile test anchor clamps to the security and the experimental data accuracy scheduling problem of fastener in tensile test process have been solved.

In order to achieve the above purpose, the utility model discloses a technical scheme is: a fastener tensile test fixture comprises a test sleeve, a protection plate, a connecting rod, a fixing nut, a conical plug pin shaft, a fixing slide block and a chute.

The test sleeve is a cylinder with a U-shaped groove at the upper end and internal threads at the lower end.

The protection plate is a semicircular cylinder with two sides provided with tapered handles.

The connecting rod is a cylinder with a U-shaped ring and divided into 3 sections with different diameters, the upper end part and the middle part are provided with threads, and a round hole is arranged between the side surfaces of the lower end.

The fixed sliding block is of a trapezoidal structure, a round hole is respectively arranged between the upper surface and the lower surface and between the side surfaces, and a groove is arranged at the bottom.

The top of the sliding groove is provided with a rectangular convex block with a round hole, and the lower end of the sliding groove is provided with a groove with the width larger than that of the convex block.

The test sleeve is embedded into the protection plate and screwed with the upper end of the connecting rod through threads; the fixed nut is screwed into the middle part of the connecting rod; the lower end of the connecting rod is embedded into a circular hole between the upper surface and the lower surface of the fixed slide block, and then the connecting rod is inserted into a circular hole between the lower end of the connecting rod and the side surface of the fixed slide block through a conical bolt shaft for connection; the lug at the top of the sliding groove is clamped in the groove at the bottom of the fixed sliding block. Thereby forming a fastener tensile test fixture.

The invention has the beneficial effects that:

the utility model discloses a guard plate design can prevent in the test process that the fastener fracture pops out the phenomenon of test fixture, has ensured the accuracy of test data and the problem of testing personnel safety.
