Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in detail.
Complexity concave curvature depth of inner cavity dip stick of the present invention mainly by scale, backup plate, vernier cursor, reference block, screw, is visited Chi and probe etc. are formed.Scale is the main body of complicated concave curvature depth of inner cavity dip stick, and scale is shaped with metric system master calibration, Master calibration unit is millimeter.One end of scale is shaped with a perpendicular backup plate, and the effect of backup plate is to determine master calibration Position benchmark and spacing to vernier cursor, its medial surface is also used as the datum level of width or linear measure longimetry;The other end of scale It is linked together by two screws and a reference block, it is ensured that the two is mutually perpendicular to.Reference block is cuboid, its lower plane It it is the measurement datum of complicated concave curvature depth of inner cavity dip stick.
Vernier cursor is arranged on scale and using it as slide rail, vernier cursor can sliding on scale, the two forms one Close-fitting moving sets.Vernier cursor and master calibration correspondence position arrange secondary scale, and read corresponding with master calibration of secondary scale is measured The decimal place of value.The upper side of vernier cursor can with the medial surface of backup plate can parallel close contact or at a distance from, this Two side-fit can make the present invention possess width or length measurement function.By two screws, vernier cursor and stock rod are connected in Together, vernier cursor synchronizing moving followed by stock rod.Stock rod is used exclusively for measuring complicated concave curvature depth of inner cavity, and its lower end is Probe, probe shape is hemispherical, in order that making stock rod and measured concave curvature is point cantact.When complicated concave curvature inner chamber When depth measuring ruler is in zero position (i.e. backup plate and vernier cursor is drawn close), the lower surface of probe is concordant with the lower surface of reference block.
Embodiment
The specific embodiment of the invention is as described below:
The implication of number designation in figure: 1 scale, 2 vernier cursors, 3 reference blocks, 4 screws, 5 probes, 6 stock rods, 7 secondary scales, 8 master calibrations, 9 backup plates, 10 complicated concave curvature workpiece, 11 spheroids.
Referring to Fig. 1 and Fig. 2, the complicated concave curvature depth of inner cavity dip stick of present invention design is mainly by scale 1, backup plate 9, vernier cursor 2, reference block 3, screw 4, stock rod 6 and probe 5 etc. are formed.Scale 1 is that complicated concave curvature depth of inner cavity is measured The main body of chi, scale 1 is shaped with metric system master calibration 8, and scale unit is millimeter.One end of scale 1 be shaped with one perpendicular Backup plate 9, the effect of backup plate 9 is the positioning datum to master calibration 8 and spacing to vernier cursor 2, and the other end of scale 1 passes through two Individual screw 4 couples a reference block 3, and the two is mutually perpendicular to.Reference block 3 is in cuboid, and its lower plane is complicated depression song The measurement datum of face depth of inner cavity dip stick.
Vernier cursor 2 is arranged on scale 1 and using it as slide rail, vernier cursor 2 can sliding on scale 1, the two is formed One close-fitting moving sets.Vernier cursor 2 and master calibration 8 correspondence position arrange secondary scale 7, and secondary scale 7 is corresponding with master calibration 8 Read the decimal place of measured value.The upper side of vernier cursor 2 can parallel close contact or leave with the medial surface of backup plate 9 Set a distance, the two side-fit can make the present invention possess width or length measurement function.Also by two screws 4 by vernier cursor 2 and stock rod 6 be connected as one, vernier cursor 2 synchronizing moving followed by stock rod 6.Stock rod 6 is used exclusively for measuring in complicated concave curvature The chamber degree of depth, its lower end is probe 5, and 5 shapes of popping one's head in are hemispherical, in order that making stock rod 6 and measured concave curvature is that point connects Touch.When complicated concave curvature depth of inner cavity dip stick is in zero position (i.e. backup plate 9 and vernier cursor 2 is drawn close), the following table of probe 5 Face is concordant with the lower surface of reference block 3.
When two width measure surface close proximity of vernier cursor 2 and backup plate 9, as in figure 2 it is shown, the main quarter on scale 1 Degree 8 is in zero-bit with the secondary scale 7 of vernier cursor 2, and complicated concave curvature depth of inner cavity dip stick is in off working state.
Refer to Fig. 3, when measuring complicated concave curvature depth of inner cavity, first complexity concave curvature depth of inner cavity is measured The lower datum level of the reference block 3 of chi contacts on concave curvature and with concave curvature, as it is shown on figure 3, moving cursor again Chi 2, drives stock rod 6 thereon to synchronize to move down, makes the probe 5 on stock rod 6 arrive to the bottom of concave curvature workpiece 10, read now The reading that master calibration 8 is corresponding with secondary scale 7, just completes the measurement of complicated concave curvature depth of inner cavity.
Refer to Fig. 4, when width or the linear measure longimetry measuring other part, such as, measure the diameter of spheroid, can will lean on Plate 9 is separated with vernier cursor 2, is put into therebetween by spheroid 11, then by the work surface of backup plate 9 and vernier cursor 2 all with tangent Form comes on spheroid 11 surface, and the reading that now master calibration 8 is corresponding with secondary scale 7 is exactly the diameter of spheroid 11.
