Problems solved by technology

Due to the fact that the shaft length of many motor equipment cannot be accurately controlled, the shaft may be too long to withstand excessive radial force, which may cause the motor shaft to break, or the shaft may be too short to drive other mechanisms connected to it.

Embodiment 1

[0040] see Figure 1-5 , a small DC motor shaft length detection device, which includes a workbench 4, the top of the workbench 4 is fixedly installed with a feeding mechanism 1 for conveying the small DC motor to be detected, and the end of the feeding mechanism 1 is installed with a The detection mechanism 2 that detects the detection of small DC motors is equipped with a sorting mechanism 3 for sorting products on the side of the detection mechanism 2. The detection device of the above-mentioned structure can be used for the detection of the shaft length of the small DC motor 103, and it adopts the mode of automatic detection, and then greatly improves its detection efficiency and quality; After being sent to the detection area, the detection sensor detects the shaft length of the motor to judge whether the small DC motor is qualified, and then distinguishes qualified products from unqualified products through the classification mechanism, thus realizing the small DC motor ...

Embodiment 2

[0049] The method for detecting the shaft length detection device of the small DC motor is characterized in that:

[0050] Step1: Roll the small DC motor 103 to be detected from the feeding ramp 102 of the feeding mechanism 1 to the U-shaped groove 104 along the slope, and maintain the initial posture;

[0051] Step2: Start the pushing cylinder 102, its piston rod stretches out, the magnet 105 at the end of the piston rod absorbs the small DC motor and pushes it to the left end along the U-shaped groove 104, and the leftmost end of the U-shaped groove 104 is provided with a baffle plate, Small DC motor 103 is pushed to stop here;

[0052] Step3: Detect the length of the main shaft of the small DC motor 103 through the pressure sensor 201 and the through-beam photoelectric sensor 202 of the detection mechanism 2;

[0053] Step4: When it is detected that the small DC motor 103 is unqualified, the magnet 105 at the end of the piston rod of the pushing cylinder 101 is released an...

Description

technical field [0001] The invention relates to the technical field of automatic mechanical equipment, in particular to a small DC motor shaft length detection device and method. Background technique [0002] In many industrial sectors, such as large steel rolling equipment, large precision machine tools, mine hoists, city trams, cable equipment, etc., where the line speed is strictly required, DC motors are usually used as prime movers to drive working machinery. The internal mechanism of the motor converts the input electrical energy into mechanical energy through the action of the magnetic field, and then drives and transmits the mechanical energy to other mechanisms through the shaft. Therefore, it is very important to strictly regulate the structure and performance of the motor shaft. Due to the fact that the shaft length of many motor equipment cannot be accurately controlled, the shaft may be too long to withstand excessive radial force, which may cause the motor shaf...
