Abstract

The invention discloses a pretightening force detection device with a self-pretightening isolation liner, and the invention relates to the technical field of isolation liner detection. The pre-tightening force detection device with a self-pretightening isolation liner directly assembles the test piece in the tube to be tested, and uses the motor to provide fastening force to ensure the stability of the connection between the test piece and the tube to be tested. By adjusting the cooperation between the cover and the fixed plate, it is fitted with the end face of the tube to be tested, so as to ensure that when the two tubes to be tested are assembled for pre-tightening force detection, the distance between the fixed plate and the upper fixed plate of the adjacent test piece is measured by the infrared rangefinder. The distance between the pipes to be detected can be used to judge the elongation of the threaded end of the pipe to be detected. This method is simple to operate and easy to use, and is suitable for pipes with various inner diameters. It reduces the cost of detection and can also be used for the assembly of the two pipes to be detected. The coaxiality is tested to realize the diversification of functions.

Description

technical field [0001] The invention relates to the technical field of isolation liner detection, in particular to a pretightening force detection device with a self-tightening isolation liner. Background technique [0002] The connection mode between bearings is the most important problem in mechanical transmission and gear transmission. Whether the connection strength is reliable, inconvenient for installation and maintenance, and whether it can adapt to harsh natural conditions are the most important issues for users, design, assembly and other units. issue concerned. The inner rib is embedded with plastic-lined steel pipe or a single carbon steel pipe is stretched and deformed into a small arc at a certain distance from the end face of the pipe using the principle of cold extrusion, and then the spring-type stainless steel clasp is placed in the groove, and a nut or interface is put on it. , The new enamel pipe fittings and their accessories can be tightened and install...
