Embodiment Construction

[0014] Such as figure 1 As shown, a bolt clamping force testing device includes a sensor connector 1, a clamping threaded roller 7, a connecting rotating disc 15, and a compression sleeve 19; the central axis of the sensor connector 1 is provided with a threaded roller screw hole 2. The central axis of the screw hole 2 of the threaded roller is centered with a limiting rod 4 , and the bottom end of the limiting rod 4 is combined with the bottom end of the screw hole 2 of the threaded roller. The central axis of the clamping threaded roller 7 is provided with a clamping threaded hole 11, and the diameter of the clamping threaded hole 11 is not less than the diameter of the limiting rod 4, so that the limiting rod 4 can be clamped in the clamping thread in use. Relatively sliding in the hole 11; the outer wall of the clamping threaded roller 7 is provided with an adjusting thread 8 corresponding to the screw hole 2 of the threaded roller, and the adjusting thread 8 in this embod...

Abstract

The invention discloses a bolt clamping force testing device. The bolt clamping force testing device comprises a sensor connector, a clamping threaded roller, a connecting rotating disc and a pressingsleeve, a threaded roller screw hole is formed in the middle shaft of the sensor connector; a limiting rod is combined in the middle of the middle shaft of the threaded hole of the threaded roller; aclamping threaded hole is formed in the middle shaft of the clamping threaded roller, and the hole diameter of the clamping threaded hole is not smaller than the diameter of the limiting rod; the outer wall of the clamping threaded roller is provided with adjusting threads corresponding to the threaded roller screw holes. A clamping threaded roller telescopic opening is formed in the position, corresponding to the clamping threaded roller, of the connecting rotating disc, and the clamping threaded roller telescopic opening and the clamping threaded roller are correspondingly provided with concave-convex fit structures; the pressing sleeve is correspondingly sleeved outside the connecting rotating disc and is tightly connected with the sensor connector through a bolt; and a plurality of rotating disc tightening holes are further formed in the pressing sleeve. The device has the advantages of being convenient to operate and high in simulation clamping accuracy.

Description
