The utility model is equipped with castor on frame.

The utility model advantage is:

1, the utility model is mainly used in the accurate dimension measurement after the PS version is sheared, and complete machine is light, flexible.

2, the complete machine bottom is equipped with the design of the dull and stereotyped castor of stopping type, changes measurement requirement and traverse measurement in various occasions easily.

3, work top adopts the two-way angle inclined design, has solved to be afraid of the problem of friction, and workpiece can be located by automatic bidirectional.Solved the error of manual positioning.Measure light, accurate.

4, single big work top is difficult to solve flatness and linearity problem, and the utility model adopts the frame structure of aluminum alloy tablet to connect, and has guaranteed the flatness of big work top and the requirement of linearity.

5, elevating mechanism adopts parallel four-bar linkage, adds the lifting that air spring is stablized big planar working table face, has guaranteed to regulate the measurement of best effort angle.

6, the XY bidirectional measurement adopts overlength grating chi, guarantees the measuring accuracy of large format flat board, can reach≤precision size within the 0.05mm.

7, the improvement and design of accurate clock gauge is adopted in the measurement of angle, has increased by a cover output software, can be on digital display meter the angles of display size.

8, the design of big planar working table flat board has solved the soft problems of measurement of large format PS plate, as long as after grating was measured the rule contact and gone up the PS plate, digital display meter showed measurement size at once, guarantees measuring accuracy.

Fig. 2 is that sketch map is looked on the left side of the utility model Fig. 1.

Embodiment:

The utility model passes through the surveying work table top 13 above two angle axle 15 connections on frame 17, work top 13 is gone into 5 ° of fixing oblique angles with frame 17 all the time in X-direction, at work top 13, Y direction is equipped with Y-axis grating chi 6 and adjacent side angle grating 7.Y-axis is measured gauge 8 and is installed on Y-axis grating chi 6 and the Y-axis grating line slideway 5, and Y-axis positive stop 9 is arranged on work top 13; With three angle digital display meters 3 movably, be installed on the angle table line slideway 4; Work top 13, X-direction are equipped with X-axis line slideway 10.Directly adopt the positive stop of the bottom of X-axis line slideway 10 as X-direction.X-axis is measured gauge 12, be fixed on simultaneously on X-axis grating chi 11 and the X-axis line slideway 10; Leading screw 18 is installed, the middle end nut of parallel fulcrum lever 21 and the threads engaged on the leading screw 18 on frame 17.The two ends of parallel fulcrum lever 21 connect both sides pin bar 14, and the top of both sides pin bar is connected with both sides, the bottom height axle 16 of work top 13.The bottom of both sides pin bar 14 connects rolling spring bearing 19.Be seated on the both sides slideway 20.The front of leading screw 18 is equipped with rising-falling tone and separates handwheel 22; Angle digital display meter 3 and XY axle digital display meter 2 also are installed on frame 17.

The utility model is equipped with the dull and stereotyped castor 1 of stopping type on frame 17.

Principle of work of the present utility model is:

After at first separating the angle of handwheel suitable operating personnel of 22 adjusting work tops and working method by rising-falling tone, earlier directions X grating mensuration gauge is touched Y before working first and make grating digital readout return " 0 " bit correction, be withdrawn into again in the relative dimensions boundary line of the PS version of surveying to position block.Again Y direction grating is measured gauge contact X and on the line slideway position block, make grating digital readout also return " 0 " bit correction, be withdrawn into the Y direction again and survey in the relative dimensions boundary line of PS version.According to the size of survey PS plate face, after angle grating was all returned " 0 " bit correction too, hand steered PS plate was close on relevant location dimension boundary line.The grating that mobile X-axis grating is measured on gauge and the Y-axis is measured gauge, is contacting the PS version on the planar line of related interfaces, and first X, Y-axis electronics indicator gauge just can show the interface dimensions of being correlated with, and precision can reach 0.01mm.Second angle digital display meter also demonstrates relevant Angular Dimension simultaneously.

The measurement of adjacent side vertical angle is left angle measurement degree, measures rear sight X, Y, Z in certain measurement range, adjusts the overhang size, pushes back and return " 0 " when position block.When the PS plate contacted at positive stop, the shown interface dimensions parameter of measurement of angle rear sight just was presented on second X, Y, three electronics indicator gauges of Z.The dimensional parameters of second electronics indicator gauge is exactly the measurement error value of adjacent side vertical angle, and measuring accuracy all in the 0.01mm scope, all can directly read by the dimensional parameters of measurement.

Continuing to measure all the other workpiece, just can work continuously and to return " 0 " to proofread and correct use again.

On measurable work top, carry out manual adjustments at the habituation and the convenience of work, select best effort angle and position, and also can whole equipment move.After the PS plate put into work top, rely on hand steered automatic location, two inclined-planes, accurately convenient.
