Description

Technical Field

[0001] The utility model relates to an online detection device for an axle ABS system, belonging to the technical field of automobile parts detection. Background Art

[0002] ABS is the abbreviation of anti-lock braking system, and its main function is to prevent the wheels from locking during emergency braking. The ABS system on the axle is composed of ABS sensor 100 and ring gear 200. Through the action of ABS sensor 100 and ring gear 200 rotating synchronously with the wheel, a set of electrical signals is output, which is transmitted to the ABS electronic control unit (ECU) on the car to realize real-time monitoring of wheel speed and brake pressure.

[0003] As an important active safety device on the axle, the axle ABS system must be tested for signals before leaving the factory to ensure the normal operation of the ABS system. At present, there are two common ABS system testing methods: one is to manually rotate the axle online for ABS signal detection, but the manual rotation speed is unstable and the labor intensity is high, the detection signal repeatability is not high, the measurement data is not easy to identify, and the reliability of the detection result is low, which can no longer meet production needs; the other is to use a special machine for off-line ABS system detection. When performing ABS system detection, the conveyor line needs to stop running, and then the workpiece is lifted off the conveyor line to a special workbench outside the line for detection. The detection accuracy is high, but it affects the production efficiency of the entire line, and the workbench adjustment is cumbersome when changing varieties, and it is not convenient for the operator to operate. Utility Model Content

[0005] The technical solution adopted by the utility model is: an online detection device for the axle ABS system, characterized by comprising a frame connected to the steel structure of the conveyor line, a lifting mechanism moving with the frame, and a driving mechanism for driving the axle;

[0006] The lifting mechanism comprises a suspension seat that cooperates with the frame for movement, and a fall arrester, a telescopic rod seat and a balancer are respectively arranged below the suspension seat; a sliding rod is slidably arranged on the telescopic rod seat, and a threaded rod with a diameter smaller than that of the sliding rod is arranged at the lower end of the sliding rod (so that the lower end of the sliding rod forms a step shape), the threaded rod passes through the middle flange plate, and is threadedly fastened with the threaded hole on the universal joint, and the middle flange plate is clamped and fixed between the universal joint and the step surface of the sliding rod; a first lifting ring is arranged on the middle flange plate, and the first lifting ring is connected to the wire rope hook of the balancer;

[0007] The driving mechanism includes a front mounting plate and a rear mounting plate, between which a fixed crossbeam and a cover shell are arranged; a servo motor is arranged in the cover shell, and the servo motor is fixedly connected to the front mounting plate through a motor connecting seat; a driving shaft is rotatably arranged on the motor connecting seat, one end of the driving shaft cooperates with the output shaft of the servo motor, and the other end passes through the front mounting plate and is fixed with a dial, which cooperates with the tire bolts on the axle; a universal joint mounting seat and a lifting ring mounting seat are arranged on the fixed crossbeam; a second lifting ring connected with the fall arrester hook is installed on the lifting ring mounting seat.

[0008] Furthermore: the frame and the lifting mechanism are matched with each other through a slide rail group, and the slide rail group includes a first slide rail group arranged on the frame and a second slide rail group arranged vertically on the first slide rail group.

[0009] Furthermore: the driving mechanism also includes a handle and an electric control handle, which are respectively arranged on the front mounting plate and the rear mounting plate.

[0010] Further: the balancer is of EWF-70 type.

[0011] Further: the servo motor is SGMGV-0503A61 type.

[0012] The beneficial effect of the utility model is that since the bed of the utility model is provided with a dial for driving the tire bolt, the positioning requirements of different models can be met by replacing the dial of the corresponding model, thereby realizing the function of compatible detection. Through the cooperation of the slide rail group and the telescopic rod, the driving component can be moved over a large range, and can be moved according to the position of the workpiece, without moving the workpiece, thereby realizing online detection. At the same time, the scheme has a simple structure, a reasonable design, and is convenient and quick to operate. It realizes the use of one device to meet the online detection of ABS systems of various models of axles, has strong compatibility, saves equipment investment, and thus reduces product processing and manufacturing costs.
