Description

Motor core drawing force detection device Technical Field The application relates to the technical field of motor iron core detection, in particular to a motor iron core drawing force detection device. Background The detection of the drawing force of the motor iron core is an important measure for measuring the bonding strength of the motor iron core and the connected components. The drawing force of the motor iron core is accurately measured, so that hidden dangers which possibly cause motor faults, such as loosening and falling of the iron core, can be eliminated in advance, stable operation of the motor under long-time and high-strength operation conditions is ensured, and on the other hand, accurate drawing force data can provide key quantitative references for optimal design and process improvement of the motor, and power-assisted motor manufacturing enterprises improve product competitiveness. In the prior art, in the key link of fixing the motor iron core, the motor iron core is sometimes temporarily fixed by adopting bonding or welding on a fixed placing table. With respect to the related art described above, the inventors consider that the placement table is difficult to clean and separate from the iron core after the completion of the inspection task, and the placement table is fragile. Disclosure of utility model The application aims to provide a motor iron core drawing force detection device which aims to solve the problem that a placing table and an iron core are difficult to separate and clean after detection tasks are completed.
