Abstract
The invention relates to a quartz weighing sensing device special for vehicle dynamic weighing and a machining method. The quartz weighing sensing device comprises an I beam type piezoelectric quartz weighing sensor and a road surface stress layer located above the sensor. A gridding cloth layer is arranged between the top face of the sensor and the road surface stress layer and adheres and is fixed to the top face of the sensor through an AB glue layer. In the machining process, firstly, the AB glue layer is brushed to the surface of alloy materials on the top face of the sensor, the AB glue layer is covered with the gridding cloth layer, after glue is completely dried, a die is installed on the upper face, the road surface stress layer is poured and compacted and stands still for 24 hours, after the road surface stress layer is completely dried, the die is detached, after the surface of the road surface stress layer is polished smooth, a foaming layer adheres to the periphery of the road surface stress layer, and then a product is acquired. Thus, the grasping force of the sensor and the road surface stress layer can be improved, the quartz sensor is protected against damage in the weighing process, and weighing accuracy and durability are improved.
