Description

Technical Field

[0001] The invention belongs to the field of information technology, and relates to an automobile balance detection device based on information technology, in particular to an automobile balance detection method based on information technology. Background Art

[0002] With the improvement of living standards, cars have become a common means of transportation. The rapid growth in demand for the number of cars has also directly promoted the rapid development of the automobile manufacturing industry. Against this background, people also have a greater pursuit of car quality.

[0003] Whether a car runs smoothly is a major criterion for judging its comfort. In addition to ensuring that the car's buffer system can work normally, it is necessary to test the car's balance.

[0004] Automobile balance detection is a critical quality control link in all rotating parts and complete machine manufacturing industries, as well as in the later operation and maintenance links. Rotating parts will have unbalanced centrifugal forces, which will cause vibration, noise, wear and tear of the rotating parts or the whole machine. If not controlled, it will greatly reduce the operating efficiency of the product, shorten the life of the machine, and in serious cases cause destructive major accidents. Therefore, all rotating parts or complete machines must pass dynamic balancing detection and correction (to minimize the unbalanced centrifugal force as much as possible) to achieve the allowable balance accuracy level, so that the mechanical vibration amplitude and noise are reduced to the allowable range, and the normal operation of the parts or the whole machine is guaranteed. Therefore, dynamic balancing test equipment is indispensable in all links of product "manufacturing-operation-maintenance".

[0005] The existing testing equipment has a single testing method and generally ignores the impact of environmental conditions, such as rainy, foggy and windy weather on the balance of the car.

[0006] Based on this, we propose an automobile balance detection device and method based on information technology, which has multiple balance detection modes, comprehensive and efficient detection, and stable data information collection and transmission. Summary of the invention

The two wheel rollers 44 are between the two wheel rollers 44, the two wheel rollers 44 are in contact with the front wheel of the car, and the front wheel and the two wheel rollers 44 rotate synchronously and stably. The two rear wheels of the car are respectively parked on the rotating wheels 36 of the rear detection mechanism 7 at corresponding positions, and the output shaft of the adjusting motor 30 drives the two transmission shaft seats 34 to rotate synchronously in the opposite direction. The transmission shaft seats 34 are connected with the two guide adjustment shafts 37 for transmission, driving the two guide adjustment shafts 37 to rotate synchronously in the opposite direction. The two guide adjustment shafts 37 drive a number of equidistantly distributed V-shaped brackets 35 thereon to rotate synchronously in the opposite direction, so that the rotating wheels 36 are in contact with the rear wheels of the locking detection car.

The output shaft of the air regulating motor 21 drives the rotating shaft of one of the wind plates 19 to rotate.

The primary filtered water obtained enters the secondary filter water tank 12. The secondary filter water tank 12 performs secondary filtration on the primary filtered water to obtain secondary filtered water. The pump 14 is used for negative pressure pumping to inject the secondary filtered water into the water collecting tank 13 for recycling and reuse.

The water used for detection is filtered, recycled and reused, which is energy-saving and environmentally friendly.

[0100] The testing room 1 cooperates with the rain-blowing and blowing mechanism 3 to realize the vehicle balance testing requirement at simulated different wind speeds.

[0101] Through the cooperation of the detection chamber 1 and the side hot air mechanism 6, the automobile as well as the front detection mechanism 8 and the rear detection mechanism 7 can be quickly dried.

[0102] Through the cooperation of the two rear detection mechanisms 7 and the two front detection mechanisms 8, the demand for stable vehicle balance detection for vehicles with different wheelbases and wheel diameters can be met, and the vehicle tilt simulation direction can be effectively adjusted.

[0103] By detecting the sensor assembly and the pressure sensors on the front and rear detection mechanisms, and cooperating with the vibration sensors and displacement sensors installed on the car, the detection information can be stably and instantly collected and transmitted to the main control background. The main control background processes the collected information to obtain more comprehensive balance information of the car, forming visual dynamic data and data model production.
