Description

Technical Field

[0001] The utility model relates to the technical field of instrument magnetism calibration, in particular to a magnetism calibration device for a motorcycle instrument. Background Art

[0002] Motorcycles are two-wheeled or three-wheeled vehicles driven by gasoline engines and steered by handlebars. They are light, flexible, and fast, and are widely used for patrols, passenger and cargo transportation, and are also used as sports equipment. In general, motorcycles are divided into street bikes, road racing motorcycles, off-road motorcycles, cruisers, and touring bikes.

[0003] The motorcycle instrument works on the principle of electromagnetic induction. It is necessary to calibrate the produced motorcycle instruments so that they can quickly and accurately indicate the driving speed. The instruments need to be calibrated before the motorcycle leaves the factory to ensure the accuracy of the instruments. The commonly used calibration method is to hold a permanent magnet close to or away from the induction end of the motorcycle instrument so that the driving speed indicated by the motorcycle instrument meets the set value. However, this method has certain shortcomings in efficiency. The operating steps of the staff are relatively cumbersome and it takes a long time to operate a motorcycle instrument. This is more obvious during batch calibration. At the same time, it also greatly increases the workload and intensity of the staff. In view of this, we propose a calibration device for motorcycle instruments. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The utility model places an instrument inside a placement slot and then uses a motor to drive a driving shaft to rotate. After the driving shaft rotates, it synchronously drives the two pulleys to rotate, and cooperates with the belt to drive the second pulley to rotate. When the second pulley rotates, it synchronously drives the threaded rod to rotate. Since the two threaded rods are mirror-imaged and the motion plate is restricted in its motion trajectory, the two motion plates are synchronously driven to move in opposite directions when the two threaded rods rotate. After the motion plate moves, the trigger plate enters the interior of the through slot, and with the help of the inclined surface of the trigger plate and the inclined slot on the sliding block, the sliding block is pushed to slide inside the telescopic slot, and then the sliding block is used to cooperate with the first telescopic rod and the second telescopic rod to drive the clamping plate to move. After the clamping plate moves, it contacts the instrument. When calibrating the magnetism of the motorcycle instrument, the instrument can be placed inside the placement slot, and the instrument is automatically fixed during the subsequent movement. The instrument is calibrated by a magnetic calibration device, thereby improving the degree of automation. The staff only needs to place the instrument inside the placement slot and take it out after the magnetic calibration is completed. BRIEF DESCRIPTION OF THE DRAWINGS

After the clamping plate 11 moves, it contacts the instrument and fixes the instrument. After contact, the spring 18 will be compressed to provide a certain stroke buffer for the clamping plate 11 to avoid damage to the instrument caused by hard support.
