Description

Technical Field

[0002] The performance test of a fan is a systematic and complex process, which involves various inspections and adjustments, such as rotation speed test, runout test, etc. Through a strict test process, it can ensure that the fan reaches the best performance in actual use. The fan assembly performance test equipment is a device used to detect and evaluate the performance of automotive fans. It usually includes a test bench for installing the fan, as well as various sensors and measuring instruments for detecting and recording the performance parameters of the fan. The rotation speed directly affects the heat dissipation efficiency of the fan, and unbalanced fan blades will cause excessive vibration, affecting the performance and service life of the fan. The existing fan assembly performance test equipment sets up separate detection units to sequentially test the fan rotation speed and fan blade vibration. After the test, it is necessary to wait for the fan to power off and stop rotating, or manually stop the fan blade rotation after the rotation speed drops. The test equipment has a complex structure, many test processes, and low efficiency. There is an urgent need for a fan assembly testing device with a simple structure, simple and fast testing, and high efficiency. Summary of the Invention

[0019] Referring to Figures 1 to 3 , a high-efficiency fan assembly test device related to the present utility model includes a workbench 1, a vertical plate 2 vertically fixed on the workbench 1, and a clamping seat 3 installed on the front of the vertical plate 2 for clamping the fan 4; a horizontal support plate 7 is installed at the bottom of the vertical plate 2 to provide support for the bottom of the clamping seat 3; four groups of grippers 32 driven by clamping cylinders 31 and used for clamping two vertical side parts of the fan 4, and a backing plate 33 for abutting against the front of the fan 4 are installed on the clamping seat 3; a plurality of data adapters 10 are installed on the vertical plate 2 for connecting the signals of the sensors to the host computer;

[0020] On the back of the vertical plate 2 at the top of the clamping seat 3, a distance measuring sensor 5 is installed to detect the distance of the fan blade. The distance measuring sensor 5 is an ultrasonic sensor. A through hole is provided corresponding to the back plate 2. When the fan rotates, the distance measuring sensor 5 detects the distance of the fan blade through the through hole, thereby measuring the beating degree of the fan blade; at the middle of the clamping seat 3, two laser sensors 6 are installed to detect the rotation of the fan blade. When the fan rotates, the two laser sensors 6 detect the fan blade successively, calculate the time and the rotated angle, and then the rotation speed of the fan 4 can be measured; the signal data of the above sensors are uploaded to the upper computer through the data adapter 10, so that the test data of the rotation speed and the beating are recorded by the MES system of the upper computer and uploaded to the database, which is convenient for quality management and traceability;

[0021] On the workbench 1 on the back of the vertical plate 2, a braking mechanism is installed, which includes a braking base 8 fixedly installed on the workbench 1, a braking cylinder 9 horizontally fixedly installed on the braking base 8, and a friction disc installed on the movable end of the braking cylinder 9; the friction disc is made of polyurethane material, which does not damage the fan 4 body during braking. Through the through hole at the central positions of the vertical plate 2 and the clamping seat 3, it contacts the central part of the fan correspondingly. When deceleration is required, the braking cylinder 9 pushes the polyurethane friction disc to contact the center of the fan to brake the fan and realize the deceleration and braking of the fan;

[0022] During fan detection, the fan 4 is manually placed on the clamping seat 3, so that the front of the fan 4 abuts against the backing plate 33. The two sides of the fan 4 are fixed by four sets of clamping cylinders 31 driving the clamping hands 32. The power plug 11 is powered on to start the fan 4. During the rotation of the fan 4, the two laser sensors 6 detect the fan blade successively, calculate the time and the rotated angle, and then the rotation speed of the fan 4 can be measured. During the rotation of the fan 4, the distance measuring sensor 5 detects the distance of the fan blade, and then the beating degree of the fan blade can be measured; after the rotation speed test and the beating test are completed, the braking cylinder 9 behind the vertical plate 2 is started, that is, the cylinder drives the friction disc made of polyurethane material to brake the rotating fan. The data of the rotation speed test and the beating test are recorded by the MES system and uploaded to the database. The fan is taken off manually, and the next fan is replaced for detection.

[0023] The utility model integrates a distance measuring sensor and a laser sensor, completes the rotation speed test and the beating test in one detection process, simplifies the structure of the test equipment and the detection operation process; after the detection is completed, the braking mechanism quickly stops the fan, saves the waiting time and improves the detection efficiency.

[0024] In addition: it should be noted that the above specific implementation manner is only an optimized solution of this patent. Any modification or improvement made by those skilled in the art according to the above concept is within the protection scope of this patent.
