Abstract
The utility model relates to a measuring mechanism, specific elasticity measuring mechanism that says so belongs to and measures technical field. It is measured body upper surface and is equipped with a plurality of gauge head connecting holes including measuring the body, measures body lower surface and is equipped with a plurality of concrete connecting holes of examining, measures body center and transversely is equipped with the measuring instrument mounting hole. The right both ends inside of measurement sinistron is equipped with longitudinal elastic and is out of shape the groove, and the measurement is personally experienced sth. Part of the body and is equipped with horizontal elastic deformation slot near examining concrete connection nose end inside, and the spread groove is passed through at horizontal elastic deformation slot both ends and longitudinal elastic deformation groove feeds through. The utility model has the advantages of simple and compact structure, rationally, convenient operation, job stabilization is reliable, can be with the highest 0.001mm that brings up to of measurement accuracy, satisfy the diameter measurement demand of high accuracy work piece.
Description
Technical field
The utility model relates to a kind of measuring mechanism, and a kind of elasticity measurement mechanism, belongs to field of measuring technique specifically.
Background technology
In prior art, during with cubing measuring workpieces diameter, the measuring mechanism of use, its core component is generally made up of a fixed block, a movable block. Wherein fixed block is connected with amesdial (or displacement transducer) mounting blocks, and movable block is connected with gauge head, between fixed block and movable block, is connected by two linear bearings. When measurement, movable block produces displacement along with the variation of diameter of work, and amesdial (or sensor), by the displacement variable of metering fixed block, obtains the variable quantity of diameter of work. But, be subject to the impact of the precision of linear bearing own, the highest can only the reaching about 0.005mm of certainty of measurement of this structure. Be no more than 1/10 of tolerance according to general measure error, this structure cannot meet the diameter measurement demand of workpiece tolerance in 0.05mm.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of elasticity measurement mechanism is provided, and can, by the highest certainty of measurement 0.001mm that brings up to, meet the diameter measurement demand of high-precision workpiece.
The technical scheme providing according to the utility model, elasticity measurement mechanism comprises measurement body, it is characterized in that: measure body upper surface and be provided with multiple gauge head connecting holes, measure body lower surface and be provided with multiple cubing body connecting holes, measure body central cross and be provided with measuring instrument installing hole; Measure inside, two ends, body left and right and be provided with longitudinal elasticity distortion groove, measure body and be provided with transverse elasticity distortion groove near cubing body connection nose end inside, transverse elasticity distortion groove two ends are communicated with longitudinal elasticity distortion groove by link slot.
Further, gauge head connecting hole is three.
Further, cubing body connecting hole is three.
Compared with the prior art the utility model has the following advantages:
The utility model is simple in structure, compact, reasonable, and easy to operate, working stability is reliable; Can, by the highest certainty of measurement 0.001mm that brings up to, meet the diameter measurement demand of high-precision workpiece.

Detailed description of the invention
The utility model is further described in connection with the embodiment in accompanying drawing below:
As shown in Fig. 1 ~ 3, the utility model mainly comprises measures body 1, measures body 1 upper surface and is provided with multiple gauge head connecting holes 2, and gauge head connecting hole 2 is for connecting gauge head. In embodiment as shown in Figure 3, described connecting hole 2 is three.
Measure body 1 lower surface and be provided with multiple cubing body connecting holes 3, cubing body connecting hole 3 is for connecting cubing body. In embodiment as shown in Figure 1, described cubing body connecting hole 3 is three.
Measure body 1 central cross and be provided with measuring instrument installing hole 4, in measuring instrument installing hole 4, install and measure instrument, measuring instrument is amesdial or sensor.
Measure body 1 inside, two ends, left and right and be provided with longitudinal elasticity distortion groove 5, measure body 1 and be provided with transverse elasticity distortion groove 6 near cubing body connecting hole 3 end inside, transverse elasticity distortion groove 6 two ends are communicated with longitudinal elasticity distortion groove 5 by link slot 7.
Operation principle of the present utility model is: in use, the utility model and cubing body, gauge head, measuring instrument are installed together, and forms a complete measurement component. Gauge head is arranged on and is measured on body by gauge head connecting hole. Measuring body is arranged on cubing body by cubing body connecting hole. Measuring instrument is arranged on and is measured on body by measuring instrument installing hole. When work, cubing body is motionless, and gauge head, along with diameter of work changes and produces displacement, is measured body also along with gauge head produces strain. Measure the longitudinal elasticity distortion groove of body, by the approximate whole part parallel-crank mechanism (being quadric chain) that become. The deflection of measuring body is delivered on measuring instrument, can read the variable quantity of diameter of work by measuring instrument (can be amesdial, can be also sensor). The measurement deflection of body and the variable quantity of workpiece radius can be similar to thinks what 1:1 exported.
