Problems solved by technology

[0002] Piezoelectric material is a kind of effect based on pressure. The material is squeezed by pressure, and the voltage appears at both ends of the material through extrusion. The characteristics of the material make the material can be used in the equipment that needs to be triggered by pressure, but for During the production of piezoelectric materials, the triggering pressure of piezoelectric materials will be changed due to the different materials added during production or the production method or process. In order to accurately grasp the various processes and add material changes The final trigger pressure of different piezoelectric materials is usually detected by force-measuring equipment. By assembling the piezoelectric material on the surface of the force-measuring equipment, and using the extrusion device of the force-measuring equipment to test the piezoelectric material Squeeze and use the numerical reading device to collect and convert the index such as the strength of the piezoelectric material squeezed by the force measuring device, so that the trigger pressure of the piezoelectric material can be clearly marked, but when the pressure detection of the piezoelectric material is performed, After the piezoelectric material is triggered, a voltage will appear in the two sections to energize the material, and when the device is working, static electricity will also appear on the surface, and the effect of the current will cause the piezoelectric material to adsorb to the device for a certain period of time after the test. test surface

Abstract

The invention provides force measuring equipment of a digital caliper based on a piezoelectric material. The force measuring equipment comprises a placing plate, a regulation and control machine, a guide seat, a display panel and a force measuring device, the left side of the placing plate is welded and fixed to the lower end of the right side of the regulation and control machine, and the upper end of the regulation and control machine is fixed to the lower end of the guide seat through a screw. When the equipment is used to detect the pressure of the piezoelectric material, the piezoelectric material is placed at the upper end of the placing plate, the force measuring device descends and extrudes the surface of the piezoelectric material by starting the equipment, when the force measuring device moves, the magnetic force can be generated when the magnetic increasing device in a lifter rotates, and due to generation of the magnetic force, the force needed by descending of the lifter is increased, the moving speed of the equipment becomes lower, and thus, the equipment is more accurate; magnetic force generated by moving is used for adsorbing and guiding voltage and current generated after the piezoelectric material is extruded, the retention degree of the voltage and current on the surface of the piezoelectric material is made to be extremely low, and the piezoelectric material is prevented from being adsorbed to the surface of the device.
