Abstract
The utility model discloses a clamp for the tensile test of a bolt, and the clamp comprises an upper clamp and a lower clamp; the upper clamp is in a cylindrical shape; the bottom of the cylindrical shape is provided with a through hole; one end of the bolt to be tested penetrates through the through hole, and the lower end of the bolt to be tested is in threaded matching and screwed with the lower clamp; and the upper end of the lower clamp is provided with a bolt hole which is matched with the bolt to be tested. According to the clamp for the tensile test of the bolt, the design is simple, the use is convenient, the bolt can be fixed reliably, and the accuracy of a test result is ensured.
Description
Technical field
The utility model relates generally to the stretching detection field, and specifically the stretching for bolt detects anchor clamps.
Background technology
The stretching of prior art detects in the anchor clamps, and the nut of bolt and screw rod can not get fixing reliably, and bolt off normal may occur or skid in drawing process, causes final testing result to lack accuracy.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of reliable fixed form to be provided, and nut is fixed in the anchor clamps of specialized designs tubular lower end, and screw rod is tightened with the anchor clamps of supporting screw by the lower end.
The utility model technical solution problem provides following scheme:
The anchor clamps that a kind of bolt tension detects comprise anchor clamps, lower clamp, and it is characterized in that: described upper anchor clamps are cylindric, and described bottom cylindraceous is provided with through hole, and an end of described bolt to be measured passes through hole, and lower end and lower clamp threaded engagement are tightened.
The upper end of described lower clamp is provided with the bolt hole that cooperates with bolt to be measured.
The anchor clamps that the utility model detects for bolt tension, supporting for each bolt size, reliably the two ends of bolt are fixed, avoided bolt off normal or skidding in the testing process, warranty test result's accuracy.
The utility model has the advantages that:
The utility model simplicity of design, easy to use, can reliably bolt be fixed, guaranteed the accuracy of test findings.
