Description
Technical field
It the utility model is related to a kind of wood craft machines or the measuring measurer of associated mechanical, especially a kind of measurement plane degree
Measurer.
Background technology
Ministry of Machine-Building Industry's standard provides flatness of the China with " line-of-sight course " detection carpenter machine tool working table face.So-called " three
Point method ", it is exactly using 3 points of plane of lie farthest away in excessively tested plane as datum plane, is detected each measuring point of plane to benchmark
The maximum algebraic step of plan range, it is the flatness error of the tested plane.
To rectangular table plane original adoption, " line-of-sight course " carries out the measurement of planeness by hand in China, and " line-of-sight course " is surveyed by hand
The principle of flatness is measured as shown in figure 1, being examined with leveling ruler and gauge block.3 points of a, b, c of selection is used as benchmark in tested plane
Point, the gauge block of three pieces of uniform thickness is placed on this 3 points, the upper surface of these gauge blocks is exactly that tested plane is put down with the benchmark made comparisons
Face.Leveling ruler is placed on a and c uniform thickness gauge blocks, an adjustable gauge block is put at the e points in tested plane, makes its lower surface with leveling ruler
Contact, at this moment the upper surface of a, b, c and e gauge block is all in the same plane.Leveling ruler is placed on the gauge block of b and e points again, in d points
An adjustable gauge block is put at place, it is contacted with leveling ruler lower surface.Leveling ruler is placed on a and d, b and c, on d and c, plane was seized can be measured
The deviation of upper each point.It can be also achieved in that for the deviation put in rectangular or square:Placed on known f and g points adjustable
Gauge block, adjustable gauge block is transferred to exact height of this away from reference plane；Leveling ruler is placed on two pieces of adjustable gauge blocks, with adjustable gauge block
(or slip gauge and clearance gauge) is the deviation between measurable tested plane and leveling ruler.Each measuring point is to the maximum difference of leveling ruler deviation
The flatness numerical value in the face, accuracy of detection can be both so improved compared to original " two-point method ", measurement efficiency can also be improved.
But operation is still cumbersome.
Utility model content
The purpose of this utility model is to coordinate displacement transducer fast and accurately to measure wood craft machines flatness, is easy to
It is fixedly mounted, it is simple in construction, it is easy to operate, substantially increase measurement efficiency.The utility model can determine one by 3 points
Reference plane, detected on the premise of unifying datum is ensured, deviation will not occur because of transformation of criterion.The utility model machine
Structure is provided with multiple grooves and pore structure, mitigates weight while sensor is easily installed.
Instrument integrated, make measurement accuracy higher, and material uses aluminium alloy, it is not only in light weight, and resistance to deformation energy
Power is strong, and the groove and pore structure in mechanism both also mitigated mechanism weight for install sensor, also 22 displacements of convenient operation
Sensor measures and gathered data, and the analog signal for being measured sensor by a/d converter is converted into data signal and led to
Cross USB interface to imported into computer, the fit Plane formed using the coordinate value of program looks importing each point, then pass through calculating
Above fit Plane the point farthest apart from fit Plane to distance and the fit Plane lower section of fit Plane apart from fit Plane most
Remote point is to survey plane flatness apart from sum to fit Plane, and this mechanism makes the measurement of planeness and calculating process more
It is convenient and swift.

Embodiment
As shown in Figure 2 and Figure 3, the utility model patent mechanism integration, is made up of, aluminium alloy is in light weight, carpenter aluminium alloy
Platen plane is often larger, it is necessary to which instrument in light weight, easy to operate to may also speed up measuring speed.Non-deformability
It is relatively strong, because the mechanism will be with displacement transducer conjunction measuring, so requiring very high, it is necessary to mechanism to the non-deformability of material
It is indeformable, it otherwise will have influence on the precision of measurement.Three pin (4,5,6) build a reference plane, the 4th pin (3) installation of mechanism
Displacement-adjustable bearing, whole mechanism is set to be fixed in tested table plane (1), with mechanism lower surface and constructed benchmark
Face is parallel, so be directly installed on 22 displacement transducers (7) in the pore structure of inside grooves, it is flat with actual measurement in lower surface
Corresponding distance is measured between face (1), as relative difference in height, because whole mechanism is in " rice " font, is dispersed with camera structure
22, hole in groove (2), 22 displacement transducers are respectively arranged in fixation in 22 holes and measured, hole and displacement transducer
Lower end, which coordinates, to be fixed, and the time of measurement is so greatly shortened, so as to improve the efficiency of measurement.It will be sensed by fore-lying device
The extension cable of device connects, and because the displacement transducer that mechanism uses is applied to high-acruracy survey, obtained simulation is believed
Follow-up computer processing number is cannot be directly used to, analog signal is converted into by data signal by a/d converter.Then, USB is passed through
Interface imported into computer and calculated by the software with correlation computations program, distance fitting above digital simulation plane
The farthest point of plane to farthest apart from fit Plane point below distance and the fit Plane of fit Plane to fit Plane away from
It is to survey plane flatness from sum, output plane degree result of calculation, completes the measurement to being detected plane flatness.
