[0022] The following describes the embodiments in conjunction with the appendix. Figure 1-3 This utility model will be described in further detail.

[0023] A tooling plate includes a base 1, which has a clearance groove 11, a positioning groove 12, a positioning hole 13, and a mounting hole 14.

[0024] The base 1 is rectangular, with arc-shaped edges extending outward from both sides. A clearance groove 11 is provided at the center of the base 1. Specifically, in this embodiment, the base 1 extends outward from both sides to form a fan-shaped edge, with the center point of the fan being the center point of the base 1. The base 1 is 186.0 mm wide, and its fan radius is 125.0 mm. The surface roughness of the mounting surface of the base 1 is no greater than 0.4 mm, the flatness of the mounting surface of the base 1 is no greater than 0.02 mm, and the parallelism is no greater than 0.02 mm. The clearance groove 11 is circular, with a diameter of 141.0 mm.

[0025] The positioning groove 12 is rectangular and includes a first positioning part 121 and a second positioning part 122. The first positioning part 121 is recessed from the surface of the base 1. The bottom of the first positioning part 121 is formed by slow wire cutting to form the second positioning part 122. The second positioning part 122 is located in the middle of the first positioning part 121. The first positioning part 121 is provided with a second mounting hole 123, which is located on both sides of the second positioning part 122. The cross-sectional size of the second positioning part 122 is smaller than that of the first positioning part 121. There are multiple positioning grooves 12, which are located on the same circle and are perpendicular to the radius of the circle. Specifically, in this embodiment, there are four positioning grooves 12. The positioning groove 12 is symmetrically arranged about the dot. The angle α between the positioning groove 12 and the vertical direction is 30.0°. The distance between the wide side of the second positioning part 122 and the long side of the first positioning part 121 is 1.0 mm. The distance between the wide side of the second positioning part 122 and the farthest point of its center is 176.2 ± 0.02 mm. The length of the first positioning part 121 is 22.0 mm, the width is 12.0 mm and the dimensional tolerance is controlled within 0.00~0.02 mm. The width of the second positioning part 122 is 4.380 mm and the dimensional tolerance is controlled within -0.04~-0.06 mm. There are two second mounting holes 123, which are symmetrically arranged and the distance between the two second mounting holes 123 is 12.0 mm.

[0026] There are multiple positioning holes 13 located on the same circle. Specifically, in this embodiment, the diameter of the positioning hole 13 is 6mm, and the dimensional tolerance is controlled within 0.00~0.02mm. The hole depth is 10.0mm. There are two positioning holes 13, which are symmetrical about the center of the circle. The angle c between the positioning hole 13 and the vertical direction is 15.0°.

[0027] There are multiple mounting holes 14, and multiple positioning holes 13 are located on the same circle. Specifically, in this embodiment, there are four positioning holes 13. The four positioning holes 13 are symmetrically arranged about the origin. The angle b between the positioning hole 13 and the vertical direction is 40.0°. The positioning hole 13 includes a countersunk head 141 and a through hole 142. The countersunk head 141 has a diameter of 15.0 mm and a depth of 8.6 mm. The through hole 142 has a diameter of 9 mm.

[0028] A structural relationship of a tooling plate:

[0029] Positioning holes 13, positioning grooves 12, and mounting holes 14 surround the clearance groove 11. Positioning grooves 12, mounting holes 14, and positioning holes 13 are arranged sequentially from the inside to the outside. Positioning grooves 12, positioning holes 13, and mounting holes 14 penetrate the base 1. The first positioning part 121 of the positioning groove 12 and the countersunk head 141 of the mounting hole 14 are located on opposite sides of the base 1.

[0030] The working process of a tooling plate:

[0031] The fixture plate is precisely positioned in the working area of ​​the comparator through the positioning hole 13, and fixed in place by the mounting hole 14 to prevent loosening. The workpiece to be tested is precisely placed on the fixture plate through the positioning groove 12 and fixed through the second mounting hole 123. Due to the rectangular structure of the positioning groove 12, the workpiece is subject to both radial and circumferential constraints, which makes the workpiece precisely positioned on the fixture plate. This avoids the comparator from being unable to detect the accuracy of the instrument due to the installation error of the workpiece during the comparison process.

[0032] The advantages of this utility model are: by using the positioning groove 12 and the positioning hole 13, the workpiece to be tested is precisely fixed in the operating area of ​​the comparator, avoiding distortion of the comparator due to the installation error of the workpiece to be tested, thereby accurately comparing the accuracy of the instrument to be tested.

[0033] The above embodiments only illustrate one implementation of the present utility model, and should not be construed as limiting the scope of the utility model patent. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of the present utility model, and all of these fall within the protection scope of the present utility model.
