Due to the particularity of its structure, the existing measuring fixture cannot meet the requirements of rapid positioning and measurement. After rotation or adjustment, the accuracy of the position cannot be ensured, so the coordinates need to be re-established for measurement, which is inefficient and slow.

[0004] Therefore, it is necessary to design a three-coordinate measuring device for disk-like structures to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a three-coordinate measuring device for a disk structure, so as to overcome the above-mentioned deficiencies in the current prior art.

[0008] Preferably, the fixed base is a T-shaped structure.

[0009] Preferably, the bottom mounting plate is arranged perpendicular to the fixed base.

[0010] Preferably, the limiting holes on the adjustable mounting plate are symmetrically arranged with the middle of the bottom mounting plate as the axis of symmetry.

[0011] The beneficial effects of this utility model are as follows: This technical solution sets up a jig with equal spacing for measuring disc-shaped products. A magnet is installed on the jig to attract the product and fix it to prevent it from falling. At the same time, a fixing rod is installed to limit the product position and adjust the product rotation angle, ensuring that the product position is consistently placed each time, thereby improving measurement efficiency. Different limiting holes are set on the adjustable mounting plate to fix and measure products of different sizes. It is universally compatible with similar disc products.

[0015] Reference Figures 1 to 2 , a three-coordinate measuring device for a disk-like structure, comprising a fixed base 1 and a fixed bracket 2 placed on the fixed base;

[0016] The fixed base is a T-shaped structure with a wide bottom for easy vertical placement, while the top is used to cooperate with the fixed bracket for installation; ensuring the stability of the base and preventing it from moving during measurement, thus ensuring the measurement accuracy;

[0017] The fixing bracket 2 is composed of an arc-shaped block 21, a bottom mounting plate 22 arranged vertically in the middle of the arc-shaped block, and adjustable mounting plates 23 respectively arranged at the ends of the arc-shaped block;

[0018] The bottom mounting plate 22 and the adjustable mounting plate 23 are evenly distributed around the center of the arc-shaped block, and the bottom mounting plate 22 is arranged perpendicular to the fixed base 1;

[0019] The bottom mounting plate 22 is disposed at an angle of 120° to the adjustable mounting plates 23 disposed on both sides.

[0020] The bottom mounting plate 22 and the adjustable mounting plate 23 are both provided with magnets 3 ; the product to be measured is adsorbed by the magnets, thereby fixing the product on the fixture for manual measurement;

[0021] In order to accommodate products of different sizes, a plurality of groups of limiting holes 4 are provided on both sides of the magnet 3 on the adjustable mounting plate 23; and the limiting holes 4 on the adjustable mounting plate 23 are symmetrically arranged with the middle of the bottom mounting plate 22 as the axis of symmetry.

[0022] In order to be able to cooperate with the product to limit the position, a fixing rod 5 is inserted into the limiting hole;

[0023] Specific implementation case, according to the corresponding size of the flywheel 6 to be measured, the fixing rod 5 is inserted into the limiting hole 4 of the adjustable mounting plate 23 on both sides, and then the flywheel to be measured is placed. The fixing rods 5 on both sides are placed on the inner ring of the flywheel and installed on the inner wall of the flywheel. The remaining parts are respectively attached to the magnets on the bottom mounting plate 22 and the adjustable mounting plate 23 for adsorption and fixation. After installation, a coordinate system is established, and the part to be measured of the product is measured and checked according to the data to be measured in the drawing. Since some dimensions are difficult to measure, the position of the flywheel needs to be adjusted and rotated. The flywheel can be directly rotated. It is only necessary to ensure that the inner ring of the product is in contact with the fixing rods 5 on both sides to ensure the position of the product. There is no need to re-establish the coordinates during measurement, which greatly improves the efficiency of measurement.

[0024] The benefits of this utility model include the use of evenly spaced fixtures for measuring disc-shaped products. Magnets are installed on the fixtures to secure the product and prevent it from falling. Fixing rods are also installed to limit the product's position and adjust its rotation angle, ensuring consistent product placement each time and improving measurement efficiency. Different limiting holes are provided on the adjustable mounting plate to secure and measure products of different sizes. This makes it compatible with all disc-shaped products.

[0025] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
