It is detected, so that subsequent spring back to it is corrected at distortion, avoids workpiece size overproof, improve workpiece accuracy.
To achieve the above object, the utility model uses following technical scheme:
A kind of arc plate detection device, including detection main body and fixed mechanism, detection main body are equipped with datum level and detection
Face, workpiece are placed on datum level, and the spacing of fixed mechanism and datum level is adjustable, and fixed mechanism and datum level clamp workpiece, are adopted
Gap width or difference between workpiece face to be detected and detection faces are measured with cubing, to judge whether workpiece size reaches precision
It is required that.
Further, the detection main body includes support frame and the reference block for being fixed on support frame upper end and detection
Block, the upper surface of reference block are the datum level, and the face to be detected that the various face of reference block and detection block corresponds to workpiece is formed
The detection faces.
Further, the datum level is plane.
Further, the detection main body is equipped with positioning pin, and shape and the corresponding aperture on workpiece of positioning pin are mutually fitted
Match.
Further, the positioning pin is quadrangular or hexagonal prisms or cylindroid.
Further, the fixed mechanism is Quick-clamped pincers, and Quick-clamped pincers are fixed in detection main body.
Further, the cubing is clearance ruler or Steel Ruler or clearance gauge.
The utility model is quickly positioned using the hole that detent fit workpiece itself has, and by datum level and admittedly
Determine mechanism and quickly fix workpiece, universal check tool, which may be selected, in used cubing can also be used self-control special gauge, and applicability is wide.Inspection
Each deformation plance of workpiece and the gap width or difference of detection faces are surveyed, for there is overproof position to mark, facilitating subsequent has needle
To property carry out segment difference correction and trimming line correction.The present apparatus can quickly detect part type face and whether detection faces coincide uniformly,
It is easy measurement, detection efficiency is high.Designed, designed and special gauge can be made by oneself, it is at low cost.

Specific embodiment
Now in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figures 1 to 7, a kind of arc plate detection device, including detection main body and fixed mechanism 3, detect main body
Equipped with datum level 21 and detection faces, fixed mechanism 3 and the spacing of datum level 21 are adjustable, and fixed mechanism 3 and datum level 21 clamp work
Part 1, using the gap width A or difference between cubing measurement workpiece face to be detected and detection faces.Fixed mechanism 3 is preferably quick
Clamping clip, Quick-clamped pincers can be conveniently and efficiently on workpiece pressings 1 to datum level 21.
The reference block 2 and several detection blocks 6 that detection main body includes support frame 5 and is fixed on support frame 5.Reference block 2
Upper surface is benchmark face 21, and the various face of reference block 2 and detection block 6 correspond to the face to be detected formation detection faces of workpiece.Preferably,
Datum level 21 is plane, and workpiece is placed on datum level 21, and fixed mechanism 3 pushes workpiece so that it is bonded datum level 21.It is fixed
Mechanism 3 and datum level 21 clamp workpiece 1, using the inspection of the universal check tools such as clearance ruler, Steel Ruler or clearance gauge or designed, designed
Tool measures gap width A or difference between the type face and corresponding detection faces of workpiece 1, to judge the segment difference and trimming line of workpiece 1
Whether size reaches required precision.
Reference block and support frame are convexly equipped with positioning pin 4, and the shape of positioning pin 4 is adapted with the corresponding aperture on workpiece 1.It is fixed
Position pin 4 is quadrangular, hexagonal prisms and cylindroid, and several positioning pins 4, which are inserted into the corresponding aperture of workpiece 1, positions workpiece 1, avoids workpiece
1 is mobile.
Operation instruction:
1) firstly, workpiece is placed on datum level, by position finger setting workpiece, clamping clip push workpiece, workpiece with
The fitting of datum level " zero " gap, clamping clip and datum level clamp workpiece jointly；
2) other than datum level and workpiece are " zero " gap-contacts, workpiece lower surface and each peripheral type face and detection are measured
The gap width A or difference in face, according to industry experience, theoretical gap width is usually 3mm or 5mm；
3) after workpiece positioning places, start to measure with cubings such as clearance ruler, Steel Ruler, clearance gauges, specifically:
With the gap width A or difference on the cubings such as clearance ruler, Steel Ruler, clearance gauge detection workpiece lower surface each periphery and detection faces
Value, and overproof value is calculated according to the following formula:
The overproof value of segment difference (also known as gap)=standard clearance value mm ± tolerance value mm；
The overproof value of trimming line=0mm ± tolerance value mm；
4) testing result illustrates that the position type face precision is overproof if the gap width A at which position is greater than tolerance value；
Such as: theoretical gap width is 3mm, and tolerance standard is ± 1.5mm, and it is 6.8mm that clearance ruler, which measures a part,
According to formula: the overproof value of segment difference (also known as gap)=standard clearance value mm ± tolerance value mm,
It obtains: 2.3=6.8- (3+1.5),
The then overproof 2.3mm of the position type face precision；
7) workpiece then, is taken pressurization on means for correcting and corrects the overproof position；
8) above step is repeated, until the gap width A between each periphery in workpiece lower surface and the detection faces of support frame does not surpass
Tolerance value is crossed, then product type face precision meets the requirements；
9) similarly detect trimming line: each edge trim line of workpiece and the theoretical difference of detection faces are 0mm.
The foregoing descriptions are merely the embodiment using this origination techniques content, any those skilled in the art use this wound
Make done modifications and changes, all belong to the scope of the patents of this creation opinion, and is not limited to those disclosed embodiments.
