Embodiment Construction

[0015] The specific implementation manner of the present invention is described in detail in conjunction with accompanying drawing and technical scheme, as appended Figure 1-11 As shown, four second connecting screws 12 are used to rigidly connect the base 1, the middle plate 2 and the four piezoelectric quartz sensors 10 through four second stepped holes e and four second threaded holes j during assembly. At the same time, the four second connecting screws 12 pre-tighten the four piezoelectric quartz sensors to obtain sufficient pre-tightening force. Four first connecting screws 7 are used to rigidly connect the middle plate 2 and the upper plate 3 through four first stepped holes i and four first threaded holes n respectively. Four screws are used to fix the piezoelectric four-dimensional cutting force measuring platform to a on the base.

[0016] When external force and torque act on the sensor, the external force can be decomposed into tangential component force F X , ...

Abstract

The invention relates to a piezoelectric-type four-dimensional cutting force-measuring platform belonging to the technical field of sensing measurement and control, in particular to a force-measuring platform for detecting normal force and torque in three directions in the cutting process. The force-measuring platform comprises a base, a middle plate, an upper plate, a lead output plug, a lead, athermal baffle, a sealing ring, four piezoelectric quartz sensors, a protective pad and connecting screws, wherein the four piezoelectric quartz sensors in diamond arrangement between the base and the middle plate are uniformly distributed on the same circumference of the same horizontal plane. The piezoelectric-type four-dimensional cutting force-measuring platform can simultaneously measures the normal force and the torque in three directions in any cutting process, has the advantages of high sensitivity, good linearity and repeatability, little transversal interference and high measurementprecision and has universality for measuring drilling, grinding, milling, lathing and planing, thereby having wide application range.

Description

technical field [0001] The invention relates to a piezoelectric four-dimensional cutting force measuring platform, which belongs to the technical field of sensor measurement and control, and in particular relates to the detection of three-direction orthogonal force and torque in the cutting process. Background technique [0002] Cutting is the most important processing method in machinery manufacturing. With the continuous development of machine tools and cutting tools, the precision, efficiency and automation of cutting processing have been continuously improved, and the scope of application has also been expanding, thus greatly promoting the development of modern machinery manufacturing. The measurement of cutting force and torque is not only conducive to the study of cutting mechanism, calculation of power consumption, optimization of cutting parameters and tool geometry parameters, but more importantly, it can monitor the cutting process through the change of cutting forc...
