Embodiment
Accompanying drawing is the wiring layout of dip stick of the hole bottom annular recess diameter of 15～75 millimeters of measurement ranges.In the accompanying drawings, upper arm (11) and underarm (12) link together with major axis (13), plain washer (15), spring washer (18) and nut (6) by their mesopore, reach that upper arm (11) and underarm (12) can relatively rotate and with major axis (13) gap minimum.Can adopt hole and axle apolegamy and the technology of grinding mutually to realize.Upper arm (11) and underarm (12) are in major axis (13) axis direction gap minimum.Just upper arm (11) and underarm (12) are in the big column end face of major axis (13) and the gap minimum between the plain washer (15).Be to realize by control major axis (13) and the length of hole mating part and upper arm (11) and underarm (12) gross thickness.
Upper arm (11) and underarm (12) are connected main scale (1) and secondary chi (2) lower end by the hole of its end with minor axis (10), plain washer (15), spring washer (18) and nut (6) respectively, and upper arm (11) and underarm (12) can relatively rotate with main scale (1) and secondary chi (2) respectively and minor axis (10) and main scale (1) and secondary chi (2) gap minimum.Also can adopt hole and axle apolegamy and the technology of grinding mutually to realize.
Main scale (1) and pad (17) are contained in the corresponding groove of secondary chi (2), and pad (17) is regulated the gap of main scale (1) in secondary chi (2) groove in main scale (1) top by jackscrew (16) and short screw (5).Method is: the small column that is contained in jackscrew (16) lower end in the screw of secondary chi top withstands in the hole of pad (17), rotate jackscrew (16) main scale (1) can be moved in secondary chi (2) groove and the gap minimum, the top that is contained in jackscrew (16) with short screw (5) is locked and is prevented to become flexible.
Vernier (3) and pressing plate (4) with screw (9) be contained in secondary chi (2) notch above, regulate the exact position of vernier (3) on secondary chi (2) by the groove on the vernier (3) and plate (7), long spiro nail (8) and two nuts (6).Plate (7) is fixed on the right-hand member bottom of secondary chi (2) with screw (9), and long spiro nail (8) is tightened on the vernier (3) by the hole on nut (6), the plate (7) and another nut (6).Unclamp the fixedly screw (9) of vernier (3), the nut (6) that rotates long spiro nail (8) upper plate (7) left side can make vernier (3) be moved to the left.The nut (6) that rotates long spiro nail (8) upper plate (7) right side can make vernier (3) move right.When adjusting to the accurate position of vernier (3) on secondary chi (2), with nut (6) locking of opposite side, it is further fixing with vernier (3) to tighten screw (9) simultaneously.
The dip stick of hole bottom annular recess diameter is to be 0.02 millimeter design by scale value.Promptly in main scale (1) is gone up certain limit, several grooves of 1 millimeter are at interval arranged, 51 grooves of 0.98 millimeter are at interval arranged on the vernier (3).
In the plane of the measurement ball center of passing through upper arm (11) and underarm (12) and major axis (13) axis normal, the measurement ball center that is contained in two minor axis axle center of main scale (1) and secondary chi (2) and upper arm (11) and underarm (12) is on the circle that with major axis (13) axle center is the center of circle and for major axis (13) axle center symmetry, two minor axises (10) axial connecting line is parallel with respect to the direction of motion of main scale (1) with secondary chi (2).According to geometrical principle, when main scale (1) and secondary chi (2) when relatively moving, the measurement ball of upper arm (11) and underarm (12) is also corresponding to be moved.The distance that upper arm (11) is measured ball and underarm (12) measurement ball equals to be contained in the distance between two minor axis axle center of main scale (1) and secondary chi (2).It also is the distance that main scale (1) and secondary chi (2) relatively move.Upper arm (11) is measured ball and is equated with the diameter that underarm (12) is measured ball.During measurement, what reflect ring groove diameter dimension on measured part (14) aperture is that upper arm (11) is measured ball and underarm (12) and measured the diameter that the distance of ball adds the measurement ball.That is to say that each measurement all is that secondary chi (2) distance mobile with respect to main scale (1) adds the diameter of measuring ball.Can go up the groove position when going up the groove position with vernier (3) at definite main scale (1), it is the diameter value of measurement ball that main scale (1) is gone up the distance that the groove starting point goes up the groove starting point apart from vernier (3).
For serviceable life of the dip stick that improves hole bottom annular recess diameter selecting the material of finished parts for use and to the cure process of part by common calliper.
When the dip stick of hole bottom annular recess diameter is measured and common calliper basic identical.It can measure the ring groove internal diameter size on the aperture of measured part (14) macropore bottom, the more internal diameter size of energy measurement part (14) macropore bottom aperture.Consider the foozle of the part of dip stick of hole bottom annular recess diameter own, the dip stick design of hole bottom annular recess diameter has regulates and locks vernier (3) is gone up the exact position at secondary chi (2) structure.Can be through the measured value of the dip stick of gauge orifice commonly used or Centigrade scale calibrated holes bottom annular recess diameter.Determine the exact position of vernier (3) on secondary chi (2) of the dip stick of hole bottom annular recess diameter by adjusting and locking mechanism.When being used to measure the same internal diameter of bulk of components, press the dip stick of the theoretical size calibrated holes bottom annular recess diameter of this internal diameter, measuring accuracy is not less than common vernier card level.
