The invention relates to a one-way machining force measuring and compensating device for cutting machining. The one-way machining force measuring and compensating device comprises a workbench, a moving assembly, piezoelectric ceramic, a convex base, workbench supports and the like; the one-way machining force measuring and compensating device is characterized in that the diameter of the convex base is reduced three times from bottom to top in a stepped mode, and the maximum part of the diameter is embedded in the upper end surface of a moving sliding table; the piezoelectric ceramic is sleevedand supported on the second step of the convex base; screws vertically penetrate through a gasket downwards and are installed on the convex base; the upper portions of the two supports are fixedly connected with the bottom of the workbench, and grooves are formed in the opposite inner side walls of the two supports; the two ends of the piezoelectric ceramic are correspondingly embedded in the grooves of the supports; the bottoms of the two workbench supports are symmetrically and fixedly installed on the moving sliding table,;and the two ends of the workbench are supported on the two workbench supports in a floating mode. By the adoption of the one-way machining force measuring and compensating device, the one-way machining force in the plane can be measured and adjusted, the cutting force is stabilized within a certain range by finely adjusting machining parameters, and the device has great significance in improving the stability of the machining quality of workpieces.
Description
technical field [0001] The invention relates to a measuring and compensating device for one-way processing force used in cutting processing, which belongs to the field of mechanical processing equipment. Background technique [0002] In the cutting process of thin-walled parts, the cutting force has a direct impact on the processing quality of the workpiece. Excessive cutting force will lead to the deformation of thin-walled parts. However, the processing force is uncontrollable in the traditional processing process. It is based on the measurement of the finished workpiece to adjust the processing parameters, and then adjust the processing force, which takes a long time, high cost and poor stability. Therefore, it is an important method to improve the processing quality of thin-walled parts to accurately measure the cutting force during the cutting process of thin-walled parts, and to control the cutting force at a stable value by changing the cutting parameters. At the sam...
