Problems solved by technology

[0002] During the production process of the motor end cover, it is necessary to install a wire thread sleeve in the bolt hole of the motor end cover (because the motor end When the bolt is connected with the threaded hole, it is easy to appear the phenomenon of sliding teeth), but in the actual production process, the phenomenon of missing the wire thread sleeve is easy to appear in the bolt hole of the motor end cover, and currently in the inspection process of the motor end cover, completely Relying on the human eye to observe whether there is a wire thread sleeve installed in the bolt hole, this detection method not only has the disadvantage of low detection efficiency, but also is prone to visual fatigue by relying on the human eye observation method, which will bring inconvenience to the detection personnel

Abstract

The invention discloses a detection tool for missing installation of a steel wire thread sleeve on a motor end cover, which includes a support plate, in which there are through holes corresponding to the bolt holes in the motor end cover, and each bolt hole in the motor end cover Both are used to install wire threaded sleeves. A detection pin is slidably installed in each through hole. The outer diameter of the detection pin is smaller than the inner diameter of the bolt hole and larger than the inner diameter of the wire threaded sleeve. The lower end surface is provided with an annular expansion part for retracting the spring, at least one handle is fixed on the upper end surface of the support plate, and the middle part of the support plate is provided with a channel for embedding the protrusion on the end cover of the power supply. The support plate and the motor A circumferential limit structure is arranged between the end covers; the present invention can detect whether there is a wire thread sleeve installed in the motor end cover, and can visually display the detection results, thus bringing convenience to the detection personnel.

Description

technical field [0001] The invention relates to the technical field of detection tooling, in particular to a detection tool for missing installation of a steel wire thread sleeve of an electric motor end cover. Background technique [0002] During the production process of the motor end cover, it is necessary to install a wire thread sleeve in the bolt hole of the motor end cover (because the motor end When the bolt is connected with the threaded hole, it is easy to appear the phenomenon of sliding teeth), but in the actual production process, the phenomenon of missing the wire thread sleeve is easy to appear in the bolt hole of the motor end cover, and currently in the inspection process of the motor end cover, completely Relying on the human eye to observe whether there is a wire threaded sleeve installed in the bolt hole, this detection method not only has the disadvantage of low detection efficiency, but also is prone to visual fatigue when relying on the human eye obser...
