Description

Technical Field

[0001] The invention relates to the technical field of motor housing testing, and in particular to a conveying testing device for a motor housing. Background Art

[0002] The motor housing is an important component of the motor. Its main function is to protect the electrical components and mechanical parts inside the motor and prevent pollution and mechanical impact from external factors such as dust, moisture, and chemicals. The motor housing is widely used in industrial automation, new energy vehicles, aerospace and other fields. Its design and manufacturing quality directly affect the performance and service life of the motor.

[0003] At present, in the process of testing the motor housing, the following problems may occur: 1. Most of them adopt manual testing methods for testing. When there are many objects to be tested, it will consume a lot of manpower and time, delaying the progress of work. In addition, it is easy to miss the test and the work efficiency will continue to decrease during the long testing process. 2. During the production or long-term use of the motor housing, some impurities are likely to adhere to the inner and outer surfaces of the housing. The adhesion of these impurities is likely to affect the test results and will also affect the service life of the housing in the long run; 3. Some motors are used in spaces with highly corrosive environments. Over time, corrosion is prone to occur on the shell, especially at the connection between the main shell and the heat sink. Long-term erosion can lead to gaps and other phenomena, thereby destroying the close contact of the connection surface, resulting in obstruction of the heat conduction path, increasing contact thermal resistance, and reducing the heat dissipation effect of the main shell. Other impurities will also invade, resulting in reduced mechanical strength and even fracture. 4. During long-term use, since the heat sink is located at the outermost edge of the motor housing, it is most susceptible to wear and external damage. Wear and damage can easily cause the heat sink to break, thereby reducing its surface area in contact with the air and directly reducing the heat dissipation capacity. Once damaged, the coating will fail and the substrate will be exposed, accelerating oxidation and corrosion.

The bottom end of the detection piece 731 is in the shape of a thin sheet, and it is movably connected to the right-angled side of the outer edge of the heat sink.

[0027] Working principle: After cleaning is completed, the driving structure at the corresponding position is controlled to move, the conveying frame 41 will move to one side of the motor housing 6, stop after moving to the specified position, and then rotate the first hand-adjusting screw rod to achieve the clamping of the motor housing 6 by the clamping arm 42. After clamping, the conveying frame 41 is controlled to move again, and the motor housing 6 will be driven to move during the movement. During the movement, the flip gear and the rack 151 will mesh, and the flip frame 43 will rotate ninety degrees, and the vertical motor housing 6 will be rotated to a horizontal state, and then move to one side of the middle frame plate 12; After reaching the designated position, the movable plate 121 is adjusted downward, and the inner wall surface of the motor housing 6 in the vertical direction is clamped by the clamping plate to complete the positioning and clamping of the motor housing 6, and then the clamping arm 42 is released and moved back to the initial position, and then the movable frame plate 17 is controlled to move until the detection ring 7 moves to the detection position on the motor housing 6, and then the positioning swivel 724 is rotated, and the probe 722 will extend forward under the action of the spring, and the top of the probe 722 will be connected to the connection between the heat sink and the motor housing 6. At this time, the pressure sensor 727 will transmit the sensing signal, and the first display light 726 will display green. At the same time, the bottom end of the detection piece 731 will contact the two ends of the outer edge of the heat sink; The movable frame 17 is controlled to move at a uniform speed again. During the movement, the probe 722 and the detection piece 731 will slide at the specified position. During the sliding process, if there is a corrosion crack or notch at the connection between the motor housing 6 and the heat sink, the probe 722 will penetrate into it under the action of the spring. If the gap is too deep, the spring clamping rod 721 will be connected to the notch to position the probe 722. At this time, the pressure sensor 727 will output the sensing signal, and the first display light 726 will show red. If there is a crack here, the problem will be recorded in time. During the movement, the detection piece 73 1 will perform a heat sink gap detection. Under the action of the spring, the detection piece 731 will continue to contact the heat sink. When it moves to the position where the gap exists, the outer shell 733 will move forward, and the detection piece 731 will be stuck in the gap position. Continuing to move forward, the detection piece 731 will slide backward on the inner wall slide bar 736. Pressing the contact will contact the second display light 732, and the second display light 732 will display red. Then the detection position is recorded. If the friction between the detection piece 731 and the heat sink is too large during the detection process, the elastic piece 735 can be adjusted to reduce the influence of the friction.
