Opposite two long sides of the fixture measurement bottom plate are respectively equipped with four steps, are inlaid with magnet, step in step
Diameter be adapted with the diameter of workpiece for measurement.
The fixed plate of three coordinates is the upper plane plate parallel with lower plane, and is arranged there are four dowel hole,
The dowel hole and fixing threaded hole penetrate through the plate of three coordinate measuring machine in a thickness direction, and the fixed plate of three coordinate passes through
Positioning pin and dowel hole are fixed on the workbench of three-dimensional coordinates measurement equipment.
The fixture support post uses the common support column of 45# steel, length and width a height of 80*80*80mm, 8 M12's
Threaded hole is respectively used to fixture measurement bottom plate and the fixed plate of three coordinates.
The size of the fixed plate of three coordinates are as follows: (240*240*20) mm, main part are 1 block of aluminium sheet, the aluminium sheet use into
6061 type high rigidity aluminiums of mouth are made, and the requirement on machining accuracy of the plate is flatness≤0.05mm, the positioning accuracy of each screw hole
Error≤0.02mm.
Fixture support post use 45# Steel material, a height of (80*80*80) mm of column length and width, flatness≤0.01mm, respectively
Positioning accuracy error≤0.02mm of screw hole.
Fixture measures bottom plate and uses 45# Steel material, and a height of (480*160*20) mm of length and width is made using embedded form of magnets
To make, step depth 10mm, the radius of curvature of 8 workpiece warehouse compartments is 0.5mm bigger than the radius of delivery valve seat to be designed, flatness≤
0.005mm, positioning accuracy≤0.01mm of 8 warehouse compartments.
Compared with the prior art and detection method, the utility model is had the prominent advantages that:
1, fixed plate is fixed on the workbench of three-dimensional coordinates measurement equipment using positioning pin, ensure that positioning tool is each
The repeatability installed again after disassembly, greatly enhances positioning and measurement accuracy.
2, fixed plate is made of high rigidity aluminium, is unlikely to deform, and positioning accuracy is high；It is mounted on three-dimensional coordinates measurement equipment
Workbench on, largely protect table surface from the erosion of oil, and be not easy to be scratched by the hard object such as workpiece, prolong
Long measuring machine service life, further increases aesthetics.
3, positioning tool can be fixed on the fixed position of three coordinate measuring machine, and not needing detection engineer, manual measurement is built again
Vertical coordinate system, three coordinates meeting automatic identification coordinate system simultaneously measure, and while improving measurement accuracy, greatly reduce repetition
The time of coordinate system is established manually.
4, part delivery valve seat fixed form is made of embedded form of magnets, can disposably be examined to population parameter
It surveys, avoids product repeated clamping from making the risk of part deformation, and effectively improve detection level and 30% or more detection efficiency.
