Description

Technical Field

[0001] The invention relates to the technical field of motor casing detection, and in particular to a detection device for a fan stretching motor casing. Background Art

[0002] Stretched motor housing, that is, the motor housing manufactured by stretching process, is mainly used to protect the electrical components and mechanical structure inside the motor, and also plays the role of heat dissipation and fixation. It is widely used in various motor equipment, and the motor equipment can be used in fans.

[0003] For example, a Chinese patent with authorization announcement number CN106052559B discloses an automatic detection device for a motor housing, including a machine platform, a feed tray is provided on the machine platform, a feed trough is provided on the feed tray, a discharge table is provided on the machine platform, a detection frame is provided in front of the discharge table, a detection optical fiber is provided on the detection frame, a first slide rail is provided on the detection frame, a first servo motor is provided at one end of the first slide rail, a connecting plate is provided on the first slide rail, a lifting cylinder is provided on the connecting plate, a finger cylinder is provided on the lifting cylinder, a second slide rail is provided on the machine platform, a second servo motor is provided at one end of the second slide rail, a stepper motor is provided on the second slide rail, and the upper end of the stepper motor is connected to the motor housing seat shaft.

[0004] However, there are still some problems with the existing motor housing detection device. In order to complete the detection of the stretched motor housing, the motor housing needs to be placed in the detection area and clamped by a clamping device. However, since the clamping device is in contact with the motor housing, it is difficult for the detection device to detect the contact area between the two during the detection work, resulting in missed detection. At the same time, since the head of the motor housing needs to be processed multiple times during the support process of the stretched motor housing, the head of the motor housing is more easily damaged than the bottom of the motor housing. When the existing detection device performs the motor housing head detection work, the detection data obtained is too little, which easily causes inaccurate detection results.

[0005] Therefore, how to avoid missed inspection of the motor housing and too little collected data is a problem that needs to be solved at present. Summary of the invention
