Embodiment Construction
[0036] The following is attached Figure 1-4 The application is described in further detail.
[0037] The embodiment of the present application discloses a non-standard workpiece inner diameter measuring instrument. refer to figure 1 , non-standard workpiece inner diameter measuring instrument, including a caliper 1 with a watch, a connecting piece 2 set on the caliper 1 with a watch, and a limit assembly 3 for fixing the connecting piece 2 to stabilize the reading.
[0038] refer to figure 1 The internal calipers 1 of the belt table include a fixed measuring claw 10 and a movable measuring claw 11, and a probe 12 is fixed vertically at the ends of the fixed measuring claw 10 and the movable measuring claw 11 respectively, and the two measuring probes 12 extend in opposite directions. A pin shaft 13 is also rotated between the fixed jaw 10 and the movable jaw 11, and the movable jaw 11 can rotate relative to the fixed jaw 10 along the pin shaft 13; an indicator 14 is also i...

The invention relates to the field of measuring tools, in particular to a non-standard workpiece inner diameter measuring instrument, which comprises a fixed measuring jaw, a movable measuring jaw, a measuring head, a pin shaft, an indicating gauge, a handle, a hand hook, a tension spring and a limiting shell, and is characterized in that one side, close to the fixed measuring jaw, of the hand hook is fixedly connected with an arc-shaped connecting sheet; the connecting sheet is movably arranged in a gap between the indicating gauge and the handle in a penetrating mode, the handle is provided with a limiting assembly used for limiting movement of the connecting sheet, the limiting assembly comprises a transmission rod connected to the handle in a sliding mode, and the length direction of the transmission rod is parallel to the length direction of the handle. One end, close to the indicating gauge, of the transmission rod is provided with two limiting sheets used for clamping and fixing the connecting sheet. The measuring instrument has the effect of improving the influence of the hand tightness degree change of the worker on the measurement result.
Description
technical field [0001] The present application relates to the field of measuring tools, in particular to a non-standard workpiece inner diameter measuring instrument. Background technique [0002] The internal snap gauge with table is a special precision measuring tool with strong practicability, which can be used to measure the size and deviation of workpiece aperture, inner ring groove diameter and step aperture, etc. It is an irreplaceable detection workpiece for general-purpose measuring tools. [0003] The calipers in the belt table are lever transmission mechanisms, which convert the movement of the measuring surface of the movable jaw into the movement of the dial gauge or dial gauge rod, and are read by the dial gauge or dial gauge. . At present, the internal calipers sold on the market generally include handles, indicators, fixed measuring claws, movable measuring claws, hand hooks, extension springs and measuring heads; the user can hold the handle and hand hook a...
