For example, the application number CN201910442463.6, a detection device for pipeline strength, discloses such a detection device. This detection device clamps the pipe fittings through two arbitrarily adjustable fixing plates to prevent the pipe fittings from moving during the detection process. , and the force direction of this fixing method is perpendicular to the surface of the pipe fitting, so that the pipe fitting will be subject to a large force, which will easily cause the pipe fitting to deform for a long time, and this detection device is difficult to detect the necking position of the necking pipe , it is necessary to manually adjust the position of the pipe fitting to find the necking place of the necking pipe fitting

The invention provides a necking part strength detection tool for a necking pipe fitting, which comprises a detection block, and two symmetrical positioning mounting blocks are fixedly arranged on the left and right end surfaces of the detection block; dust on the surface of a pipe fitting can be blown away through the fan, the necking position of the pipe fitting is determined according to the change of the air speed after the pipe fitting passes through the fan, automatic positioning of the necking positions of different necking pipes is achieved, the positioning block is controlled to fix the position of the pipe fitting through the point control switch, and the positioning efficiency is improved. The movement positions of the positioning blocks deviate from the circle center of the detection channel, so that one part of stress on the pipe fitting is parallel to the pipe wall, the damage of positioning to the pipe fitting is reduced, and the deformation of the pipe fitting is prevented; the vibration sensor arranged on the attaching assembly is used for monitoring vibration when the pipe fitting deforms, and therefore whether the pipe fitting is qualified or not is judged.
Description
technical field [0001] The invention relates to the technical field of pipe fitting detection, in particular to a strength detection tool at the constriction of a constricted pipe fitting. Background technique [0002] In the process of pipe fittings processing, it is often necessary to perform a shrinking operation on the pipe fittings to facilitate the connection and installation of the pipe fittings, and after the pipe fittings are produced, the strength of the pipe fittings needs to be tested to discharge defective products and prevent the pipe fittings from breaking during use; For example, the application number CN201910442463.6 discloses a detection device for pipeline strength, which clamps the pipe fittings through two arbitrarily adjustable fixing plates to prevent the pipe fittings from moving during the detection process , and the force direction of this fixing method is perpendicular to the surface of the pipe fittings, so that the pipe fittings will be subject...
