The invention discloses a bolt fastening demonstration apparatus and a bolt fastening parameter display method. The bolt fastening demonstration apparatus is composed of a first flange, a second flange, a bolt assembly, a sealing pad, a display device, a first cylinder, and a second cylinder. The first cylinder and the second cylinder have opening ends; the opening end of the first cylinder is connected with the first flange in a sealing mode and the opening end of the second cylinder is connected with the second flange in a sealing mode; and the first flange and the second flange are in a butt joint mode and are fixedly connected by the bolt assembly. The sealing pad is arranged between the first flange and the second flange. The bolt assembly contains a plurality of bolts penetrating the first flange and the second flange and nuts screwed at the bolts; and drawing force sensors are embedded into the heads of the bolts. The display device is connected with the drawing force sensors, thereby displaying fastening parameters corresponding electric signals outputted by the drawing force sensors. On the basis of the technical scheme, the fastening parameter changing situation of the bolts during the fastening process can be known visually by the operator; and thus the stress principle of the bolt fastening can be mastered.
Description
technical field [0001] The invention relates to the field of bolt fastening operations, in particular to a bolt fastening demonstration device and a bolt fastening parameter display method. Background technique [0002] At present, in the production of most products, there is a bolt fastening process. At present, the way for operators to tighten bolts is to use tightening tools to pull up and tighten the bolts until all the bolts on the product are tightened; but the operators do not understand the force changes of the bolts during the tightening process And the deformation situation, the operator is performing the fastening work completely by experience. Therefore, it is easy to cause some bolts on the product to be deformed and damaged, or the uneven tightening degree of the bolts will cause product quality problems and so on. [0003] Therefore, it is very meaningful to propose a bolt fastening demonstration device so that the operator can grasp the force change or defor...
