新型卡箍测力器的研制

Development of New Force Measuring Device for Work Carrier

卡箍测力器利用帕斯卡原理进行油压测量,从而获得卡箍夹紧力。研制一种适用于小型卡箍类环形零件夹紧力测量的装置,通过旋入调节螺杆使液压腔的压力增大,推动测杆向外伸长使卡箍向外张开,读压力表的读数,通过查夹紧力与油腔压力的关系表得到卡箍的夹紧力。

By force-measuring device, clamp force of work carrier is gotten through measuring its oil pressure based on Pascal principle. A new force-measuring device was developed that was used for a type of small work carrier type ring parts. By rotating its ad- justed screw, pressure of the hydraulic cylinder would be increased, and pushed the measuring rod outside. At that time, clamp force of the work carrier would be gotten through consulting the table of force and pressure.
