Description

Technical Field

[0001] This utility model relates to the field of measuring instruments, and in particular to an instrument for calibrating inner diameter gauges that conforms to the Abbe principle. Background Technology

[0002] An inside diameter gauge is a combination of a lever-type measuring frame and a dial indicator, used to measure or inspect the diameter and shape accuracy of the inner hole and deep hole of a part. However, current common methods for measuring the inside diameter using dial indicators often do not conform to Abbe's principle. For example, a dial indicator calibrator disclosed in patent document CN202267431U uses a locking bolt to fix the gauge rod. The angle at which the rod is fixed is prone to swing with the locking bolt, causing the contact head and micrometer to be out of collinear, which does not conform to Abbe's principle and results in relatively low measurement accuracy. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an internal diameter gauge calibrator that conforms to Abbe's principle. The measurement results obtained by this solution conform to Abbe's principle, enabling more accurate measurement of internal diameter gauges.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an inner diameter gauge calibrator that conforms to the Abbe principle, including a calibrator body and a positioning component;

[0005] The calibration instrument includes a base and a vertically arranged calibration station;

[0006] The positioning assembly includes a column, a lifting platform, a suspension rod, and a clamp;

[0007] The column is vertically fixed to the base, the lifting platform is slidably fitted to the column, one end of the suspension rod is horizontally inserted through the lifting platform, the clamp is fixed to the suspension rod, the clamp is horizontally provided with a V-groove, the direction of the V-groove is pointing towards the inspection station, and a pressing component is provided above the V-groove.

[0008] During use, place the gauge rod of the inside micrometer into the V-groove, with the contact head of the gauge placed at the calibration station. Since the V-groove is horizontal, and the contact head and gauge rod are perpendicular, the contact head can be adjusted to a vertical position. More specifically, the centerline of the contact head should be aligned with the centerline of the calibration station to achieve a measurement conforming to Abbe's principle, resulting in more accurate measurements. After aligning the contact head with the centerline of the calibration station, use a pressure member to fix the gauge rod in place. The V-groove helps to better determine the centerline of the gauge rod.

[0009] Preferably, the lifting platform has a first through hole in a vertical direction, the column passes through the first through hole, and a first fastening bolt is provided on the side of the lifting platform, with the front end of the first fastening bolt abutting against the side wall of the column. This facilitates better adjustment of the height of the lifting platform.

[0010] Preferably, the lifting platform has a second through hole arranged laterally, one end of the suspension rod passes through the second through hole, and a second fastening bolt is provided on the side of the lifting platform, with the front end of the second fastening bolt abutting against the side wall of the suspension rod. This facilitates better adjustment of the relative position of the suspension rod to the lifting platform.

[0011] Preferably, the clamp has a third through hole through which the suspension rod passes, and a third fastening bolt is provided on the side of the clamp, with the front end of the third fastening bolt abutting against the side wall of the suspension rod. This facilitates better adjustment of the relative position of the suspension rod with respect to the clamp.

[0012] Preferably, the clamping seat has a clamping opening on its side, the lower sidewall of the clamping opening has a downward-facing V-groove, and the upper sidewall of the clamping opening has a pressing member. This facilitates better fixation of the dial indicator rod.

[0013] Preferably, the pressing member is a fourth fastening bolt with threads adapted to the upper sidewall of the clamp, and the end of the fourth fastening bolt points towards the V-groove. This facilitates pressing the gauge rod by rotating the fourth fastening bolt.

[0014] Preferably, the clamps include at least two. This provides better support for the dial indicator rod.

[0015] Preferably, the clamp is provided with a positioning through hole parallel to the V-groove, and also includes a laser lamp whose light is collinear with the positioning through hole. The relative position of the two clamps can be determined by illuminating the positioning through hole with the laser lamp. If the light passes through the positioning through holes of both clamps at the same time, the two clamps are in the same position, specifically, the V-grooves of the two clamps are collinear.

[0016] The beneficial effects of this utility model are:

[0017] The measurement results obtained through this method conform to Abbe's principle, enabling more accurate measurement of the inner diameter of the gauge. Attached Figure Description

[0023] Example

[0024] like Figure 1 As shown, an inner diameter gauge calibrator conforming to the Abbe principle includes a calibrator body and a positioning assembly. The calibrator includes a base 1 and a vertically arranged calibration station 2. The positioning assembly includes a column 3, a lifting platform 4, a suspension rod 5, and a clamp 6. The column 3 is vertically fixed to the base 1, the lifting platform 4 is slidably fitted to the column 3, one end of the suspension rod 5 is horizontally inserted through the lifting platform 4, the clamp 6 is fixed to the suspension rod 5, the clamp 6 is horizontally provided with a V-groove 7, the direction of the V-groove 7 is towards the calibration station 2, and a pressing member 8 is provided above the V-groove 7.

[0025] In use, the gauge rod of the inside diameter gauge is placed in the V-groove 7, with the contact head of the gauge placed at the calibration station 2. Since the V-groove 7 is horizontally positioned, and the contact head and gauge rod are perpendicular to each other, the contact head can be adjusted to a vertical position. More specifically, the axis of the contact head is aligned with the centerline of the calibration station 2, achieving a measurement conforming to the Abbe principle, resulting in more accurate measurements. After aligning the contact head with the centerline of the calibration station, the gauge rod is fixed in place using the pressing component 8. The V-groove 7 effectively determines the axis of the gauge rod.

[0026] The lifting platform 4 has a first through hole in a vertical direction, through which the column 3 passes. A first fastening bolt 9 is provided on the side of the lifting platform 4, with the front end of the first fastening bolt 9 abutting against the side wall of the column 3. This facilitates better adjustment of the height of the lifting platform 4.

[0027] The lifting platform 4 has a second through hole arranged laterally. One end of the suspension rod 5 passes through the second through hole. A second fastening bolt 10 is provided on the side of the lifting platform 4, and the front end of the second fastening bolt 10 abuts against the side wall of the suspension rod 5. This facilitates better adjustment of the relative position of the suspension rod 5 to the lifting platform 4.

[0028] The clamp 6 is provided with a third through hole, through which the suspension rod 5 passes. A third fastening bolt 11 is provided on the side of the clamp 6, and the front end of the third fastening bolt 11 abuts against the side wall of the suspension rod 5. This facilitates better adjustment of the relative position of the suspension rod 5 with respect to the clamp 6.

[0029] Combination Figure 2 As shown, the clamp 6 has a clamping opening on its side, the lower side wall of the clamping opening has a downward-facing V-groove 7, and the upper side wall of the clamping opening has a pressing member 8. This facilitates better fixation of the dial indicator rod.

[0030] The lower pressure member 8 is a fourth fastening bolt 12 with a thread that fits into the upper side wall of the clamp, and the end of the fourth fastening bolt 12 points towards the V-groove 7. This facilitates pressing the gauge rod by rotating the fourth fastening bolt 12.

[0031] The clamp 6 includes at least two clamps. This provides better support for the dial indicator.

[0032] The clamp 6 is provided with a positioning through hole 13 parallel to the V-groove 7, and also includes a laser lamp whose light is collinear with the positioning through hole 13. The relative position of the two clamps 6 can be determined by illuminating the positioning through hole 13 with the laser lamp. If the light simultaneously passes through the positioning through holes 13 of both clamps 6, then the two clamps 6 are in the same position; specifically, the V-grooves 7 of the two clamps 6 are collinear. In this design, the laser lamp can be fixed to the suspension rod.
