Embodiment
Embodiment:
As shown in Figure 1, for solving the problem, the technical scheme that the utility model adopts is:
A kind of individual event dynamic force sensor, comprise power transmission upper cover 11, piezoelectric patches 12, electrode 13, plug 14 drawn by motor, insulating material 15, base 16, described insulating material 15 is arranged in base 16, described electrode 13 one end is provided with insulating material 15, described electrode 13 other end is provided with electrode and draws plug 14, and described piezoelectric patches 12 is arranged on electrode 13 outer ring, and described power transmission upper cover 11 is arranged on the top of base 16.
Further, the insulating material 15 that described electrode 13 passes one end is drawn plug 14 with electrode and is connected, and by the setting of multiple insulating material 15, further ensure that insulation effect.
Further, described individual event dynamic force sensor 1 is arranged on the below of lathe tool 2.
Further, described lathe tool 2 is arranged on knife rest 3.
Further, described lathe tool 2 side is provided with workpiece 4.
Piezoelectric patches 12 must have certain pretightning force first can ensure in individual event dynamic force sensor 1, and piezoelectric patches 12 is when stressed, all the time be under pressure, secondly the nonlinearity erron caused because of loose contact between two piezoelectric patches 12 can be eliminated, ensure to export the linear relationship between input action power, but this pretightning force can not be too large, otherwise will affect its sensitivity.
Individual event dynamic force sensor 1 is mainly used for the measurement of dynamic force, vibration acceleration, as the test of lathe dynamic cutting force.
As shown in Figure 1, made piezoelectric patches 12 produce electric charge in the axially effect of being stressed by dynamometry by power transmission upper cover 11, two pieces of piezoelectric patches 12 stack vertically in the other direction, and centre is a sheet shape electrode 13.Two piezoelectric patches 12 positive charge sides are connected with the power transmission upper cover 11 of individual event dynamic force sensor 1 and base 16 respectively.Therefore two pieces of piezoelectric patches 12 are together in parallel, and improve the sensitivity of individual event dynamic force sensor 1.Electrode 13 is drawn plug 14 by electrode and is exported by electric charge.
Fig. 2 utilizes unidirectional dynamic force sensor 1 to measure the schematic diagram of Tool in Cutting power, and individual event dynamic force sensor 1 is positioned at the below of lathe tool 2 front end.Before cutting, although lathe tool 2 is pressed on individual event dynamic force sensor 1, the moment that piezoelectric patches 12 is compressing also once produced very large electric charge, and within several seconds, electric charge has just been neutralized by the bleeder resistance of circuit.In working angles, lathe tool 2 is under the effect of cutting force, and upper and lower severe vibration, passes to unidirectional dynamic force sensor 1 by pulsating force.The charge variation amount of unidirectional dynamic force sensor 1 converts voltage to by charge amplifier, then records the variable quantity of cutting force with registering instrument.
Owing to have employed technique scheme, compared with prior art, individual event dynamic force sensor of the present utility model, volume is little, quality is light, sturdy construction, bandwidth, highly sensitive, measurement range is wide, is therefore most widely used.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structure change made under enlightenment of the present utility model, and every have identical or akin technical scheme with the utility model, all belongs to protection domain of the present utility model.
