The invention has the advantages that: can be adapted to measurements quick and precisely in enormous quantities, the super-large diameter parts, and simple to operate, precision is high, size accommodation is big.
For more detailed explanation the present invention, following accompanying drawing provides two most preferred embodiments.
Description of drawings:
Fig. 1 is the structure cut-open view of measuring workpieces external diameter of the present invention;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the structure cut-open view of measuring workpieces internal diameter of the present invention;
Fig. 4 is the vertical view of Fig. 3;
Embodiment:
Embodiment one: as shown in Figure 1 and Figure 2, the ultra-large diameter accurate detector of a kind of measuring workpieces external diameter provided by the invention is characterized in that comprising ingredient:
One, the base plate 10 of a strip, its right side is provided with wide portions 10a;
Two, left side of face arranges an instrument holder 2 on the base plate 10, connects the sleeve part of measurement instrument 1 feeler lever 3 on the instrument holder 2 by screw, regulates the position of fixed muffle part by screw, can adapt to the workpiece calibration of measuring different-diameter;
Three, near medium position a slide block 4 and a chute 18 that cooperates slip with slide block 4 are set above the base plate 10, between slide block 4 and instrument holder 2, be provided with spring 19, the thrust of spring 19 makes slide block 4 away from the probe 3 of measurement instrument 1 all the time, make slide block when not having measuring workpieces, do not form with the probe of measurement instrument and contact cooperation;
Four, connect an endpoint location pin 16 with screw on the slide block 4, the lower end of endpoint location pin 16 is passed slide block 4 and chute 18 and is extended beyond base plate 10 following.The middle part of endpoint location pin 16 is provided with a support ring 17, and the one side of support ring contacts cooperation with base plate 10, another side can cooperate with the end face of ring standard gauge 11 (or workpiece for measurement).The lower end of endpoint location pin 16 is provided with a benchmark locating ring 15 and contacts cooperation with the face of cylinder of ring standard gauge 11 (or workpiece for measurement).
Five, the other end at base plate 10 is provided with wide portions 10a, the position relative with endpoint location pin 16 arranges two fixed locating studs 12, this two fixed locating studs 12 and endpoint location pin 16 constitute three reference points of measurement standard ring gauge 11 (or workpiece) diameters, and namely three reference points have directly recorded the diameter data of ring standard gauge 11.When measuring workpieces, contact by the summit of slide block 4 with feeler lever 3, in the difference of measurement instrument 1 reaction measured workpiece diameter and ring standard gauge 11.
Each fixed locating stud 12 middle part is provided with a support ring 13 in addition, and the one side of support ring contacts cooperation with base plate 10, another side can cooperate with the end face of ring standard gauge 11 (or workpiece for measurement).Fixed locating stud 12 lower ends are respectively equipped with a benchmark locating ring 14 and contact cooperation with the face of cylinder of ring standard gauge 11 (or workpiece for measurement).
