They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the utility model.

[0026] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "setting", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, an indirect connection through an intermediate medium, or the internal connection of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] As shown in the figure, the utility model includes: a conveying mechanism 3, used to move the stator 18 to be detected to the detection position; a tooling platform 2, which is placed above the conveying mechanism 3, and the stator 18 to be detected is placed on the tooling platform 2; a detection tool 1, including a tooling table, a pneumatic clamp 4 arranged on the side of the tooling table, and a detection probe 5 installed on the pneumatic clamp 4. When the stator 18 to be detected on the tooling platform 2 moves to the detection position, the detection probe 5 on the pneumatic clamp 4 can contact the detection terminal 17 of the stator 18 to be detected.

[0028] The conveying mechanism 3 includes two parallel conveyor belts 10, and the tooling platform 2 is placed on the conveyor belts 10 and is conveyed forward by the conveyor belts 10. A lifting assembly 11 is provided between the two conveyor belts 10, and the lifting assembly 11 is located at the detection position, and is used to lift the tooling platform 2 and move the detection terminal 17 of the stator 18 to be detected between the pneumatic clamps 4. The lifting assembly 11 includes a lifting cylinder 15 installed below the conveying mechanism 3, a lifting plate 14 connected to the lifting cylinder 15, a positioning pin 12 fixedly connected to the surface of the lifting plate 14, and a positioning hole 16 provided below the tooling platform 2. When the tooling platform 2 moves to the detection position, the positioning pin 12 can dock with the positioning hole 16 and lift the tooling platform 2. In this example, two positioning pins 12 are preferably set on the surface of the lifting plate 14. The lifting plate 14 is a rectangular structure. The two positioning pins 12 are located at diagonal positions on the surface of the lifting plate 14. In addition, a plurality of support columns 13 are also set on the surface of the lifting plate 14 for supporting the tooling platform 2 when it is lifted.

[0029] At the same time, a base 7 is fixedly connected above the tooling platform 2, and the base 7 includes a side plate 6. The stator 18 to be detected is placed on the base 7. A positioning cylinder 9 is installed at the bottom of the tooling platform, and the positioning cylinder 9 is connected to a positioning plate 8.

At this time, the detection terminal 17 of the stator 18 to be detected is located between the pneumatic clamps 4; the pneumatic clamps 4 dock the detection probe 5 with the detection terminal 17, and the detection point on the docking product is powered on, and the power supply tooling supplies power to the stator product at the same time; at this time, the motor detection cabinet located next to the detection device starts to detect and collect data (such as resistance test, insulation test, turn-to-turn test, and withstand voltage test), and detects it to determine whether it is qualified.

[0032] The utility model can complete the precise docking of the detection probe through the coordination relationship among the transmission mechanism, the lifting assembly, the tooling platform and the detection tooling, thereby reducing manpower input, improving the accuracy and work efficiency of detection, and better adapting to the work of the assembly line to create greater economic benefits for the enterprise; at the same time, the worker only needs to complete the wiring work between the power supply tooling and the stator to be detected before detection, and no manual participation is required during the test, which can avoid accidents during the test and ensure the normal and smooth progress of the detection section.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
