Fig. 2 is top plan view of the present invention.
In figure: 1-base plate, 2-dial indicator holder, 3-side plate, 4-panel, 5-location-plate, 6-floating seat, 7-positioning core axle, 8-reed briquetting, 9-spring leaf, 10-set screw, 11-activity orientation block, 12-dial gauge, 13-stopping screw, 14-firm banking.
Embodiment
As shown in Figure 1, the present invention comprises a rectangle base plate 1, and wherein a long side is provided with dial indicator holder 2.Dial indicator holder 2 horizontal component is connected with base plate 1 by socket head cap screw, which is provided with two pieces of activity orientation blocks 11, described activity orientation block 11 lower end is formed with the through hole of left and right directions in figure, upper end forms the screw hole of fore-and-aft direction in figure, during use, by the table shank portion of dial gauge 12 through lower end through hole, then screw is through by two activity orientation block 11 upper end screw holes, firmly fixes table handle.
Both sides, base plate 1 upper surface long limit are provided with side plate 3, are left plate, right plate respectively according to direction shown in figure.Side plate 3 supports the panel 4 covered on it, and panel 4 is the rectangles with base plate 1 consistent size, and two long side relative positions are respectively provided with three screw holes, and meanwhile, left and right side plate and base plate 1 relevant position are also provided with screw hole.Side plate 3, dial indicator holder 2 are fixed together through base plate 1 by socket head cap screw firmly.Base plate 1, left plate, right plate, panel 4 constitute a hollow body, and be provided with firm banking 14 and floating seat 6 in hollow body, firm banking 14 is squares, and underrun socket head cap screw is fixed on base plate 1.
Below floating mount 6 structure is described in detail.
Can see that from Fig. 2 band floating mount is square build shape, upper surface is not closed, and left and right sidewall is provided with spring leaf 9, and these two spring leafs extend to firm banking about 14 sidewall.Two spring leafs 9 are by 4 pieces of reed briquettings 8 and screw by floating seat 6 and firm banking 14 chain connection, and floating seat 6 can swing around the short width gapless of firm banking 1.It is noted herein that, a less gap (not shown in FIG.) is provided with between floating seat 6 and base plate 1, ensure floating of floating seat 6, floating seat 6 and firm banking 14 consistent size, the centre symmetry line of bottom surface base plate (1) long side direction is in same straight line.In order to limit the axially-movable of floating mount 6, be provided with the screw hole of left and right directions in figure on left and right side plate top, set screw 10 is through screw hole, and end is near reed briquetting 8.Positioning core axle 7 is arranged in floating seat 6 hole, and positioning core axle 7 freely can rotate in floating seat 6, realizes location of floating, and the annular groove inserting floating seat 6 by stopping screw 13 limits its axial location.It should be noted that, the bottom center of floating seat 6, positioning core axle 7 overlaps, and is positioned on the projection line of dial indicator holder 2 through hole axial line vertical direction, ensures the degree of accuracy measured.
Also it should be noted that, be also provided with a through hole at right plate and activity orientation block 11 through hole relative position, the contact part of dial gauge 12 is through right plate near reed briquetting 8, and when measurement, the deformation of perception spring leaf 9, obtains measurement data.
Below positioning core axle 7 is described in detail.
Positioning core axle 7 is renewal parts of detecting instrument, be equipped with according to different tested parts, various positioning core axle 7 is all located with tested pin-and-hole, flat side or flute profile Elastic Contact, eliminates clamping interference or clamping gap that Dimension Measurement deviation causes to the impact of measured value, guarantees accurate positioning.The elastic deformation scope of positioning core axle 7 should meet the limit deviation of tested part key element, makes it to ensure intimate contact.Axially run to limit positioning core axle 7, the present invention is provided with a screw hole at floating mount, and stopping screw 13 is through screw hole, and end is close to positioning core axle 7.
Below location-plate 5 is described in detail.
Two location-plates 5 are located on panel 4, and as can see from Figure 2, its both sides relative position is provided with three pairs of annular screw holes, can be fixed on panel 4 by screw.Positioned parallel groove is formed between two location-plates 5.Its groove width can be adjusted according to different tested part external diameter size lining bars.And make tested part axle center substantially be placed in centre.
Below using method of the present invention is described.
Before apparatus measures, according to tested part external diameter size adjustment groove width; According to element to be measured, select suitable positioning core axle 7, and be fit in floating seat 6; Be arranged on by standard component in the positioned parallel groove between positioning core axle 7 and two location-plates 5, according to standard component symmetry numerical value calibration dial gauge scale value 0, then changed by tested part and compare measurement, measured value and 0 potential difference value are multiplied by 2 and are symmetry numerical value.Comparing and measuring if do not used, by twice measurement of tested part change of direction, difference can be measured twice and being symmetry numerical value.
The present invention adopts parallel slot positioning workpieces cylindrical, swing sheet spring hinged support, location element to be measured-i.e. pin-and-hole, flat side or flute profile is floated by elastic central spindle, eliminate the measuring error caused because of workpiece size deviation, for measuring the symmetry of axle class pin-and-hole, flat side and groove.The present invention adopts standard component to compare and measure, and measured value is directly perceived, accurately, efficiency is high, and being convenient to grasp, is a kind of applicable symmetry somascope.
Compared with existing axle class symmetry measuring technique, the invention has the beneficial effects as follows: the present invention measures numerical stability, repeatable accuracy high (below 0.005mm); Intuitive display, convenient and reliable operation, do not affect by processing dimension, as long as change different positioning core axle and adjustment locating slot width, just can measure various axle class pin-and-hole, flat side and flute profile symmetry, be a kind of broad-spectrum general profile shaft class symmetry detector, both can use in operation processing, also can be used for finish turn inspection.
