Abstract

The utility model relates to a special bolt testing clamp, which is composed of an upper clamp, a lower clamp and a nut clamp. The upper clamp and the lower clamp are respectively arranged on an upper clamping head and a lower clamping head of a tension tester. The nut clamp is arranged on the lower clamp. The utility model is characterized by the hollow framework of the upper clamp. The utility model has the advantages of simple structure, fast, convenient and accurate operation, etc.

Description

The special bolt test fixture
Technical field
The utility model belong to parts such as threaded fastener, material fast, make things convenient for, stretch accurately, the technical field of torture test, particularly a kind of special bolt test fixture.
Background technology
The mensuration of the axial pre tightening force of double thread securing member in rundown process is the problem of being paid close attention to always, adopt the ultrasonic measurement way can solve this difficult problem, but must be fixed at the enterprising rower of tension tester to bolt, the bolt tension anchor clamps of using always can't be realized the demarcation to bolt.
Summary of the invention
The purpose of this utility model is to provide a kind of special bolt test fixture convenient, fast, that exactly bolt is demarcated at the deficiency of above-mentioned anchor clamps.
The technical solution of the utility model is: it is made up of last anchor clamps, lower clamp, nut clamp etc., last anchor clamps, lower clamp are installed in respectively on the upper and lower chuck of tension tester, nut clamp is installed on the lower clamp, it is characterized by: going up anchor clamps is the framed structure of hollow.
The utlity model has simple in structurely, use characteristics such as quick, convenient, accurate.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The technical solution of the utility model is: it is made up of last anchor clamps 1, lower clamp 2, nut clamp 3 etc., last anchor clamps 1, lower clamp 2 are installed in respectively on the upper grip 5, lower chuck 6 of tension tester, nut clamp 3 is installed on the lower clamp 2, it is characterized by: go up anchor clamps 1 and be the framed structure of hollow.
Below in conjunction with accompanying drawing the utility model is described further, as shown in the figure: the special bolt test fixture is made up of last anchor clamps 1, lower clamp 2, nut clamp 3 (nut) etc.; Last anchor clamps 1, lower clamp 2 are installed in respectively on the upper and lower chuck 5 and 6 of tension tester, the distance between the anchor clamps is adjusted in testing requirements according to bolt; To test bolt 4 installs.
Before process of the test, ultrasonic probe is pull-in on the bolt head, carry out in the drawing process at bolt, just the numerical value that the numerical value and the ultrasonic measurement of tension tester can be gone out compares, and the bolt force value is demarcated.
