[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0021] The structures, proportions, and sizes illustrated in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0022] like Figures 1 to 3 As shown, a preferred embodiment of a dynamic balancing and weight-removing hole measuring fixture is illustrated, comprising: a base plate 1, a fixed base 2, a mounting column 3, a dial indicator 4, a tapered mandrel 5, a locking rod 6, and an expansion sleeve 7.

[0023] The lower surfaces of the fixed base 2 and the mounting column 3 are respectively mounted on the two ends of the upper surface of the base plate 1; a mounting through hole is opened on the outer wall of the mounting column 3, and the dial indicator 4 has a measuring rod 15, which extends into or out of the mounting through hole; the lower end of the tapered mandrel 5 is mounted on the fixed base 2, the expansion sleeve 7 is sleeved on the outer wall of the tapered mandrel 5, and a pull rod hole 8 is opened at the upper end of the tapered mandrel 5, which extends vertically; the lower end of the locking pull rod 6 is installed in the pull rod hole 8, and the locking pull rod 6 drives the expansion sleeve 7 to move vertically.

[0024] In actual use, before measurement, a standard sample is placed on the tapered mandrel 5 to verify the gauge. After verification, the part to be measured is placed on the tapered mandrel 5 and the locking rod 6 is locked. When locking the locking rod 6, the locking rod 6 will move downward, which will drive the expansion sleeve 7 to move downward, thereby fixing the part to be measured. After fixing, the measuring rod 15 with the dial indicator 4 is used to measure the de-weighting hole of the part to be measured. The diameter and front taper dimension of the measuring rod 15 are consistent with the design requirements of the drawing. When the measuring rod 15 contacts the de-weighting hole of the part to be measured, the dial indicator 4 at the rear end can directly read the relative position of the de-weighting hole space, thereby completing the measurement.

[0025] Based on the above, this utility model also has the following embodiments:

[0027] Furthermore, a dynamic balancing and de-weighting hole measuring fixture further includes: a plurality of fixing screws 10; a plurality of first fixing holes are formed on the upper surface of the mounting ring 9, the plurality of first fixing holes being arranged sequentially along the circumference of the mounting ring 9; a plurality of second fixing holes are formed on the upper surface of the base plate 1; and the lower end of each fixing screw 10 passes through a corresponding first fixing hole and extends into a second fixing hole. Furthermore, the mounting post 3 is installed using the fixing screws 10, facilitating disassembly and thus enabling convenient and quick maintenance.

[0028] Furthermore, a dynamic balancing and weight-removing hole measuring fixture is provided, wherein a shaft hole 11 is formed on the upper surface of the fixed base 2, and the lower end of the tapered mandrel 5 is installed in the shaft hole 11.

[0029] Furthermore, a dynamic balancing and de-weighting hole measuring fixture further includes: a locking screw 12; a locking hole is formed on the outer wall of the fixing base 2, the locking hole extending horizontally along its length and communicating with the shaft hole 11; one end of the locking screw 12 is installed in the locking hole and contacts or disengages from the outer wall of the tapered mandrel 5. Furthermore, the tapered mandrel 5 is fixed by the locking screw 12, thereby facilitating the replacement and maintenance of the tapered mandrel 5, and enabling the testing of parts of different specifications.

[0030] Furthermore, a dynamic balancing and de-weighting hole measuring fixture further includes: an adjusting shim 13, the lower surface of which abuts against the upper surface of the fixed base 2; and a clamping ring 14 extending radially outward from the outer wall of the middle portion of the tapered mandrel 5, the lower surface of which abuts against the upper surface of the adjusting shim 13. Furthermore, the adjusting shim 13 facilitates adjustment of the position of the tapered mandrel 5 to improve measurement accuracy.

[0031] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
