Abstract
The invention provides a multi-range macro and micro force sensor which is characterized in that a rectangular loading block is connected to a base through a first-stage elastic sheet, two second-stage elastic sheets are symmetrically distributed on the two sides of the first-stage elastic sheet, one ends of the second-stage elastic sheets are connected with rectangular middle blocks, the other ends of the second-stage elastic sheets are connected to the base, two rigid limiting blocks are respectively connected to the base, the two opposite lateral sides of the rectangular middle blocks get close to the corresponding lateral sides of the rectangular loading block and the corresponding lateral sides of the rigid limiting blocks respectively in a small-gap mode, and strain foil is pasted on the upper side and the lower side of the first-stage elastic sheet and the upper sides and the lower sides of the second-stage elastic sheets respectively. According to the multi-range macro and micro force sensor, measurement on multi-range macro and micro force can be achieved.
Description
Technical field
The invention belongs to manufacturing technology field, specifically relate to the grand Micro-force sensor of a kind of multirange.
Background technology
Sensor industry is acknowledged as the most promising industry at home and abroad, have the advantages such as high technology content, wide market application foreground, good economic benefit, power sensor is widely used in the occasions such as laboratory, design office, workshop as a common tool.Power sensor accuracy and range are the important indicators of measurement power sensor mass.
Application number is a kind of differential type horizontal micro force measuring device and the measuring method that the open Liao Fei Wang Yong of polytechnical university of 201110212466.4 patent document etc. proposes, and is mainly used in measuring 10
-2small power below N.Application number is that the patent document of CN200710132017 discloses the red 2 D force transducer in small measurement range proposing that waits of the lucky love of Nanjing Aero-Space University, can be in the two-dimentional contact force of Measurement accuracy small-range within the scope of environment temperature-10～40 ℃, and there is good dynamic perfromance.Application number is a kind of dual rate force transducer that the patent document of CN200680037603 discloses the JS Browning proposition of Custom Sensors & Technologies, it has applied a spring that machining is manufactured, provide two kinds of different spring constants and a plurality of sensor to measure different ratios, this dual rate force transducer complicated structure, the rigging error of sensor can reduce the precision of sensor.
Current power sensor often can not be taken into account high precision and two indexs of wide range, when the variation range of power is larger, uses current power sensor often can not realize accurate measurement.
Summary of the invention
The object of this invention is to provide and a kind ofly can overcome above-mentioned defect, there is multirange, can accurately measure the device for measuring force of Wei Lihe GSMC simultaneously.Its technical scheme is:
The grand Micro-force sensor of a kind of multirange, it is characterized in that: rectangle loading blocks is connected in pedestal by one-level elastic sheet, two secondary elastic sheets are symmetrically distributed in the both sides of one-level elastic sheet, one end of secondary elastic sheet connects rectangle intermediate mass, its other end is connected in pedestal, two rigid limit pieces are connected to pedestal, two opposite flanks of rectangle intermediate mass approach with the little gap of respective side of rectangle loading blocks and rigid limit piece respectively, and foil gauge is all pasted in the both sides up and down of one-level elastic sheet and secondary elastic sheet.
Compared with prior art, its advantage is in the present invention: (1) this device has a plurality of ranges, and in the situation that not only needing to measure GSMC but also need to measure micro-power, automatic range switching, can realize accurate measurement; (2) avoided to a certain extent, because of outrange, device for measuring force is caused to damage; (3) simple in structure, maintenance cost is low.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
In figure: 1, pedestal 2, one-level elastic sheet 3, rectangle loading blocks 4, secondary elastic sheet 5, rectangle intermediate mass 6, rigid limit piece.
