Embodiment
For making purpose of the present invention, technical scheme clearer, the invention will be further described below in conjunction with the accompanying drawing specific embodiment.
Referring to Fig. 1~Fig. 7, when the internal diameter that will measure is interior angular thread, test probe replaceable can be changed into 8 and 14, come checking dimension by length bar then.Concrete operations are in proper order: earlier with an external screw thread micrometer length bar by traditional method with two gauge heads of an external screw thread micrometer to good, two 60 ° interior angular thread test probe replaceable 8 and 14 with this multiplex inside micrometer goes external screw-thread micrometer just to two good gauge heads then, like this, the size of two of female thread micrometer gauge heads just can reach the size of length bar.In adjustment process, can regulate with the front and back nut 16 and 18 that multiplex inside micrometer elbow gauge head is regulated, fixing, during measurement referring to the schematic diagram of Fig. 6.
Should use the digital display micrometer inside caliper more, on drive mechanism, the thread rotary orientation direction of the thread rotary orientation of the opposite or micrometric screw of the direction of the direction of hook tooth and outside micrometer hook tooth and the micrometric screw of outside micrometer is opposite, and measuring principle is equal to outside micrometer.
Transmission principle is: when gauger's turn device for measuring force, micrometric screw 22 promotes elbow test aircraft 20 and does the front and back slippage, and the mode of promotion is that micrometric screw locating slot 7 and the micrometric screw dog screw 23 of forward end drives.Elbow is surveyed the slipper of frame 20 and is ensconced many insides with micrometer inside caliper blade 6, its surface is provided with circular locator slide 27, elbow is surveyed the axial slip of frame 20 by 26 controls of measuring staff slideway positioning ball, measuring staff slideway positioning ball 26 is located by micrometer slideway set screw, when gauger's turn device for measuring force, slippage before and after its elbow measuring staff can be done thereupon, the gap precision between each drive disk assembly can be controlled by precision manufacturing and check and correction length bar.
Should many shells with the digital display micrometer inside caliper are fixing parts of digital display assembly, outer casing frontispiece be provided with groove, and the digital display assembly is fixed in the groove.The effect foot of digital display assembly is received the electric signal of moving grid and Ding Shan state relative motion generation by 34 Data Input Interfaces, convert digital signal to, show the displacement of micrometric screw by display 35 again, thereby measure the size of workpiece, the digital display assembly no longer describes in detail here for existing mature technology.
When needs are measured diameter of bore or internal channel size, can be with reference to the schematic diagram of Fig. 5 and Fig. 7, the readings principle method is the same.The middle part of elbow test aircraft is provided with the leptoprosopy 20 that can allow two elbow test aircrafts interlaced, and leptoprosopy also can design the multiplex inside micrometer that leans on mutually side by side non-intersect mistake with wide arc-shaped transitional surface 19.Such as Fig. 5, Fig. 6 and shown in Figure 7.
This multiplex digital display inside micrometer is novel in design unique, has ingeniously solved the difficult problem that existing internal thread is measured difficulty, has filled up the blank of field of machining, for the various inner diameter measurements of machining provide very big convenience.
