Abstract
A high-frequency fatigue test clamp for a smooth sample comprises a clamping nut, a high-frequency fatigue test clamping block, a sliding seat, a rotating bolt and a connecting rod. Due to the combined design of the clamping nut, the high-frequency fatigue test clamping block and the sliding seat, the smooth sample can be fixedly installed, so that the problem of difficulty in installation of the smooth sample is solved, and the accuracy of the data of the smooth sample in the fatigue test process is guaranteed.
Description
Technical Field
The utility model relates to a fatigue test field, concretely relates to high frequency fatigue test anchor clamps of smooth sample.
Background
With the development of the reform and the opening of China for decades, the manufacturing industry, the basic industry, the aerospace industry and other industries of the China in a new era which appear along with modern science and technology make great progress. Meanwhile, better and better requirements are provided for detection tests of innovative high-quality materials, parts of various machines, whole vehicles and various engineering machines, and the development brings opportunities for the development of the field of fatigue tests.
Common clamps used for fatigue testing include wedge-shaped clamps (plate clamps) and screw-type clamps (bar clamps). However, at present, a lot of bar samples are not provided with threads, so that the samples cannot be effectively fixed due to the fact that the surfaces of the samples are difficult to mount smoothly in the high-frequency fatigue test process, and test data are not prepared.
Disclosure of Invention
The utility model aims at solving the above problem and providing a high frequency fatigue test anchor clamps of smooth sample to the installation of smooth sample in high frequency fatigue test process and the inaccurate scheduling problem of test data have been solved.
In order to achieve the above purpose, the utility model discloses a technical scheme is: a high-frequency fatigue test clamp for a smooth sample comprises a clamping nut, a high-frequency fatigue test clamping block, a sliding seat, a rotating bolt and a connecting rod.
The clamping nut is a conical sleeve with threads inside.
The high-frequency fatigue test clamping block is a conical clamping block with a V-shaped groove on the surface and a sliding groove at the bottom.
The slide seat is composed of two sections of cylinders with different diameters, a rectangular bump is arranged on the surface of the upper end cylinder, and the lower end cylinder is of a threaded structure.
The rotary bolt is a cylinder with a thread structure at the upper end part and a tapered handle at the outer side of the lower end part.
The connecting rod is composed of three sections of cylinders with different diameters, the upper end of each cylinder is provided with a threaded hole, and the lower end of each cylinder is provided with a thread.
The rotary bolt is sleeved on the connecting rod, the sliding seat is screwed into the connecting rod through the rotary bolt, the convex block on the surface of the cylinder at the upper end of the sliding seat is clamped into the sliding groove at the bottom of the test clamping block, and the clamping nut and the rotary bolt are screwed together by rotating the conical handle of the rotary bolt. Thereby forming a high-frequency fatigue test fixture for smooth samples.
The invention has the beneficial effects that:
the utility model discloses a step up the combined design of nut, high frequency fatigue test clamp splice and slide, can be with smooth sample fixed mounting to solve the problem of smooth sample installation difficulty, ensured the accuracy of smooth sample data in the fatigue test process simultaneously.
