Description

Technical Field

[0001] The utility model relates to motor detection equipment, in particular to automobile air-conditioning fan detection equipment. Background Art

[0002] The structure of the automobile air-conditioning fan mainly includes the impeller and the motor. The air-conditioning fan will be directly used on the automobile production line after leaving the factory. Therefore, the automobile air-conditioning fan must be a fully qualified product before leaving the factory. The last process before the automobile air-conditioning fan leaves the factory is inspection. The traditional inspection method is to power on the inspection to check whether the motor is operating normally. The inspection is not comprehensive, resulting in some motor lines being connected in reverse, causing the impeller to reverse, which will affect the air output of the automobile air conditioner. At the same time, the output of current and voltage is not within the specified range, which can easily lead to unstable operation of the air-conditioning motor and greatly affect the service life of the motor. This increases the failure rate of the car and affects the reputation of the car brand. Utility Model Content

The test motor 40 is energized to drive the wind wheel 30 to rotate and drive the detection motor 20 to rotate. The detection motor 20 is connected to the electrical parameter meter, which has a display. The electrical parameter meter displays the detected values on the display and compares them with the motor process parameter table to detect whether the voltage and current output by the test motor 40 to drive the detection motor 20 to rotate meet the requirements and check whether the rotation direction of the wind wheel 30 meets the requirements.

Through the above steps, the test results of the air conditioner fan motor can be quickly obtained, effectively improving the efficiency of the test.

[0020] The above-mentioned testing process can be carried out by automobile air-conditioning fan testing equipment, such as Figure 1 、 Figure 2 As shown, the automobile air-conditioning fan detection equipment is a double-station, and its structure includes a platform 1. The platform 1 is sequentially provided with a motor placement device 2, a wind wheel loosening and clamping device 3, and a detection motor drive device 4. The detection motor 20 is connected to the electrical parameter meter, and the electrical parameter meter includes a host and a display. The motor placement device 2 includes a liftable positioning support plate 21 and a left and right movable positioning slide 22. The positioning slide 22 is provided with a positioning hole 221. A groove for the positioning support plate 21 to pass through is provided below the positioning hole 221. The positioning support plate 21 passes through the groove. The aperture of the positioning hole 221 is adapted to the outer diameter of the motor 40 to be tested. The positioning slide 22 can be replaced according to the specifications of the motor to be tested. Therefore, the positioning support plate 21 requires different slides and motor positions for lifting and lowering adjustment. The positioning support plate has a "V"-shaped positioning groove, and the motor 40 to be tested can be placed The wind wheel 30 is positioned on the positioning groove and then pushed into the positioning hole for positioning. The wind wheel loosening and clamping device 3 includes a frame 31 installed on the platform 1, and finger cylinders 32 are respectively provided on the left and right sides of the frame 31. The two movable ends of the finger cylinder 32 are respectively connected with "L"-shaped clamps 33. The two sides of the wind wheel 30 are clamped or loosened by the two clamps 33. The wind wheel 30 is loosened during detection, and the wind wheel 30 is clamped and fixed after the detection is completed. The detection motor drive device 4 includes a frame 41 connected to the platform 1, and a cylinder 42 is connected to the frame 41. The piston rod of the cylinder 42 drives the detection motor 20 to extend and retract forward and backward. The cylinder 42 and the above-mentioned finger cylinder 32 are respectively connected to the air pump through an electromagnetic valve, and the electromagnetic valve is controlled by the main engine. One end of the wind wheel 30 is provided with a plug-in transmission with the output shaft of the detection motor 20, and the other end of the wind wheel 30 is plug-in transmission with the output shaft of the motor 20 to be detected.

[0021] The motor placement device 2 also includes a plate 23 mounted on the platform 1, with a guide rail 24 placed horizontally on the plate 23, and a slider sliding along the guide rail 24, the positioning slide 22 is detachably connected to the slider by screws, and an adjusting screw 25 is screwed on the plate 23, and a lifting plate 23 is connected to the bottom plate of the positioning support plate, and a first guide rod is arranged on the lifting plate 23 and inserted into the first guide hole on the plate 23 for lifting and lowering movement. One end of the adjusting screw 25 is rotatably connected to the bottom of the lifting plate 23 through a bearing, and the other end of the adjusting screw 25 is connected to a handwheel 26. When the handwheel 26 is operated to drive the adjusting screw 25 to rotate, the lifting plate 23 can be driven to move up and down, thereby matching the position of the motor to be tested (or with test) in the positioning slide 22, so as to better position the motor with test, and at the same time, an insertion rod is screwed on the positioning slide 22, which can be rotatably inserted into the inner hole of the positioning slide 22 to position the motor 40 to be tested.

[0022] Among them, the detection motor drive device 4 also includes a servo motor 43 and a push plate 44. The servo motor 43 is also controlled by the main machine. The output shaft of the servo motor 43 is connected to the output shaft of the detection motor 20 through a coupling 45. It is plugged into the output shaft of the detection motor 20 at one end of the middle hole of the wind wheel 30. The other end of the middle hole of the wind wheel 30 is equipped with an internal threaded sleeve 301. The servo motor 43 drives the internal threaded sleeve 301 to rotate and is threadedly connected to the output shaft of the motor with detection.

At the same time, the servo motor 43 drives the coupling 45 and the detection motor 20 to rotate to rotate the wind wheel 30. While the wind wheel 30 rotates, it moves toward the direction of the motor 40 to be detected so that the internal threaded sleeve 301 in the wind wheel 30 is threadedly connected to the output shaft of the motor 20 to be detected. In this way, the transmission connection between the motor 20 to be detected and the wind wheel 30 can be quickly realized.

[0023] The operations of the equipment's cylinder 42, finger cylinder 32, servo motor 43, and detection motor 20 are mainly controlled by the host and set through a program, achieving a technical effect of one-button start testing.

[0024] By adopting the above technical solution, after the motor to be tested is positioned by the motor placement device, the detection motor driving device drives the detection motor to be connected to the wind wheel transmission, and the wind wheel is loosened through the wind wheel loosening clamping device. The detection motor driving device also drives the wind wheel to cooperate with the motor to be tested for transmission. Then the tested motor is energized, and the rotation of the wind wheel drives the output shaft of the detection motor to rotate, so that the detection motor generates output current. The electrical parameter meter displays the detected value through the display and compares it with the motor process parameter table. In this way, the voltage, current and other parameters output by the test motor driven by the test motor meet the requirements, and at the same time, check whether the rotation direction of the wind wheel is correct. In this way, comprehensive and reliable detection technical effects are achieved, thereby greatly reducing the failure rate of automobile air-conditioning fans.
