Description

Technical Field

[0001] This invention relates to the field of key spacing and dimension measurement technology for automobiles, and more specifically, to a tool for measuring the spacing of automobile pedals. Background Technology

[0002] For ergonomic and safety reasons related to braking and acceleration systems, some vehicle manufacturers have specified requirements regarding the distances between the brake and accelerator pedals. These requirements include, for example, the distance between the left edge of the brake pedal and the edge of the foot pedal, the distance between the right edge of the brake pedal and the center console, and the distance between the brake and accelerator pedals. Figure 1 and Figure 2 As shown. For the above three distances, it is necessary to randomly select a portion of mass-produced vehicles for actual vehicle measurements to determine whether the distances meet the requirements. However, during actual vehicle measurements, the relatively small interior space and the fact that the objects being measured are not on the same plane make measurement difficult and time-consuming. Therefore, a tool that can quickly and accurately determine whether the distances meet the requirements is urgently needed.

[0003] Invention Patent Content

[0004] To address the aforementioned technical problems, this invention provides a tool for measuring the distance between automotive pedals. The tool is shaped to fit the floor of the driver's cab and fixedly placed within the cab. The distance between each pedal to be measured is converted into the distance between the pedal and a reference plate, simplifying the measurement process and improving accuracy.

[0005] The present invention solves the technical problem by adopting the following technical solution:

[0006] A tool for measuring the distance between automotive pedals includes a base, a reference plate, and a brake pedal extension plate; wherein,

[0007] The base includes a first contouring portion and a second contouring portion. The first contouring portion includes at least a first end that matches the shape and size of the foot pedal contour at the connection between the foot pedal contouring portion and the floor, a second end that matches the shape and size of the seat beam contour at the connection between the seat beam contouring portion and the floor, and a third end that matches the shape and size of the door sill contour of all or part of the door sill contouring portion. The x-direction distance between the first end and the second end is the same as the x-direction distance between the foot pedal contouring portion and the seat beam contouring portion. The second contouring portion includes at least a fourth end that matches the shape and size of the center channel contour at the connection between the center channel bottom contouring portion opposite to the door sill near the foot pedal and the floor. The y-direction distance between the third end and the fourth end is the same as the y-direction distance between the door sill contouring portion and the center channel bottom contouring portion.

[0008] The reference plate includes a first reference plate and a second reference plate vertically disposed on the second contouring part. The first reference plate and the second reference plate extend in the x direction to the widest point in the y direction of the brake pedal. The y-direction distance between the first reference plate and the second reference plate is greater than the widest y-direction distance of the brake pedal. The z-direction height of the first reference plate and the second reference plate is not lower than the highest point in the z-direction of the brake pedal.

[0009] The brake pedal extension plate is connected to the side wall of the second reference plate, which is away from the first reference plate, and extends in a direction away from the first reference plate; the plane containing the bottom surface of the brake pedal extension plate is parallel to the tangent at the point where the curvature of the brake pedal foot surface is the greatest.

[0010] The end face of the brake pedal extension plate is adapted to the shape and size of the upper contoured part of the central channel opposite to the foot pedal; the y-direction distance between the third end and the end face of the brake pedal extension plate is the same as the y-direction distance between the door sill contoured part and the upper contoured part of the central channel.

[0012] Furthermore, the plane containing the top surface of the brake pedal extension plate is coplanar with the tangent plane at the point of maximum curvature of the brake pedal foot surface, and the distance H3 between the tangent plane at the point of maximum curvature of the brake pedal foot surface and the bottom surface of the brake pedal extension plate is the thickness between the top and bottom surfaces of the brake pedal extension plate.

[0013] Furthermore, the second contoured portion includes a horizontal portion and a curved portion, which makes the base more securely fixed in the cab and prevents it from moving.

[0014] Furthermore, H1 is 85%-98% of W1; H2 is 90%-99% of W2; and H3 is 80%-98% of W4, thus reducing the distance that needs to be measured.

[0015] Furthermore, H1 is 94%-96% of W1; H2 is 95%-98% of W2; and H3 is 85%-95% of W4.

[0016] Furthermore, it also includes a measuring block, the thickness of which includes A1, A2, A3, A4 and A5. The measuring block is used to measure the spacing, which simplifies the measurement process and allows for quick judgment of the measurement results.

[0017] A1 = Minimum standard distance between the foot pedal and the brake pedal W1 - Y-direction distance H1 between the first reference plate and the right edge of the first end;

[0018] A2 = Minimum standard distance W2 between the brake pedal and the center channel - Y-direction distance H2 between the second reference plate and the upper contour block of the center channel;

[0019] A3 = Maximum standard distance between the brake pedal and the center channel W3 - Y-direction distance H2 between the second reference plate and the upper contour block of the center channel;

[0020] A4 = Minimum standard distance between the brake pedal and the accelerator pedal; W4 - Thickness H3 between the top and bottom surfaces of the brake pedal extension plate;

[0021] A5 = Maximum standard distance between the brake pedal and the accelerator pedal; W5 - Thickness H3 between the top and bottom surfaces of the brake pedal extension plate.

[0022] Furthermore, the measuring block is step-shaped, and the distance between the opposite faces of the first and last steps of the measuring block is the maximum value among A1, A2, A3, A4, and A5.

[0026] Furthermore, a second reinforcing plate perpendicular to the second contouring portion is provided on the second contouring portion. The second reinforcing plate and the reference plate are located on the same side of the base. The ends of the first base, the second base and the support plate are fixed to the second reinforcing plate.

[0027] Furthermore, the end face of the brake pedal extension plate extends to a point below the foot surface of the accelerator pedal, increasing the contact area between the brake pedal extension plate and the central channel.

Stretch the first plane to the left to form a first reference plate. Make a first mark on the base at the intersection of the right side of the first reference plate and the base.

[0031] S3. Obtain a second plane in the 3D model that extends from the brake pedal to the middle channel, covers the middle area of ​​the accelerator pedal, and is coplanar with the tangent plane at the point of maximum curvature of the brake pedal surface. Then stretch the second plane towards the accelerator pedal direction H3 to the third plane to form a tangent plate.

[0032] S4. In the 3D model, obtain a fourth plane with a y-direction distance of H2 from the end face of the tangent plate furthest from the brake pedal, located between the brake pedal and the accelerator pedal, in the area above the base and not lower than the highest point of the brake pedal in the z-direction, and perpendicular to the plane and / or curved surface of the base.

Detailed Implementation

[0049] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

Furthermore, it should be noted that the x-direction is the vehicle length direction, the y-direction is the vehicle width direction, and the z-direction is the vehicle height direction. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0051] This invention provides a tool for measuring the distance between automotive pedals, such as... Figure 3As shown, the tool includes a base 4, a reference plate, and a brake pedal extension plate 7. When using this tool, the base 4 is placed on the driver's cab floor and needs to be prevented from shifting. Therefore, the front end of the base 4 needs to abut against the foot pedal 2, the rear end against the seat crossbeam 15, the left end against the door sill 13, and the right end against the center tunnel 14. The front, rear, left, and right abutment ends of the base 4 need to be contoured according to the outlines of the foot pedal 2, seat crossbeam 15, door sill 13, and the connection points of the center tunnel 14 with the floor. The portion or all of the foot pedal 2 that needs to be contoured is the contoured portion of foot pedal 2; the portion or all of the seat crossbeam 15 that needs to be contoured is the contoured portion of seat crossbeam 15; the portion or all of the door sill 13 that needs to be contoured is the contoured portion of door sill 13; and the portion of the center tunnel 14 that needs to be contoured is the contoured portion of center tunnel 14. The base 4 includes a first contoured portion 41 and a second contoured portion 42, generally L-shaped. The first contoured portion 41 includes at least a first end 411 that matches the shape and size of the contour of the foot pedal 2 at the connection between the contoured portion of the foot pedal 2 and the floor, a second end 412 that matches the shape and size of the contour of the seat beam 15 at the connection between the contoured portion of the seat beam 15 and the floor, and a third end 413 that matches the shape and size of the contour of the door sill 13 of all or part of the contoured portion of the door sill 13. The first end 411... The x-direction distance between the third end 413 and the second end 412 is the same as the x-direction distance between the contoured portion of the foot pedal 2 and the contoured portion of the seat crossbeam 15. The second contoured portion 42 includes at least a fourth end 421 whose shape and size are adapted to the contour of the bottom contoured portion of the central passage 14 opposite to the door sill 13 near the foot pedal 2 and the floor connection. The y-direction distance between the third end 413 and the fourth end 421 is the same as the y-direction distance between the contoured portion of the door sill 13 and the bottom contoured portion of the central passage 14. The second contoured portion 42 includes a horizontal portion and a curved portion. The curved portion has the same contour as the portion of the cab floor extending upward toward the engine compartment, making the base 4 more securely fixed in the cab and preventing movement.

[0052] The reference plate includes a first reference plate 5 and a second reference plate 6 vertically disposed on the second contouring portion 42. When the second contouring portion 42 includes a horizontal portion and a curved portion, the reference plate is perpendicular to both the horizontal portion and the curved portion. The first reference plate 5 and the second reference plate 6 extend in the x-direction to the widest point in the y-direction of the brake pedal 1. The y-direction distance between the first reference plate 5 and the second reference plate 6 is greater than the widest y-direction distance of the brake pedal 1. The z-direction height of the first reference plate 5 and the second reference plate 6 is not lower than the highest point in the z-direction of the brake pedal 1. The first reference plate 5 and the second reference plate 6 are located on the left and right sides of the brake pedal 1, respectively, and can cover the widest and highest points of the brake pedal 1.

[0053] The brake pedal extension plate 7 is connected to the side wall of the second reference plate 6, which is away from the first reference plate 5, and extends in a direction away from the first reference plate 5. Generally, the foot surface of the brake pedal 1 is curved, while the foot surface of the accelerator pedal 3 is either flat or curved. The plane containing the bottom surface of the brake pedal extension plate 7 is parallel to the tangent plane at the point of maximum curvature of the foot surface of the brake pedal 1. When the tangent plane at the point of maximum curvature of the foot surface of the brake pedal 1 is parallel to or parallel to the tangent plane at the point of maximum curvature of the foot surface of the accelerator pedal 3, the plane containing the bottom surface of the brake pedal extension plate 7 is also parallel to or parallel to the tangent plane at the point of maximum curvature of the foot surface of the accelerator pedal 3. The end face of the brake pedal extension plate 7 is adapted to the shape and size of the upper contoured part of the central channel 14 opposite to the foot pedal 2. The y-direction distance between the third end 413 and the end face of the brake pedal extension plate 7 is the same as the y-direction distance between the contoured part of the door sill 13 and the upper contoured part of the central channel 14, so that the end face of the brake pedal extension plate 7 abuts against the central channel 14.

[0054] The y-direction distance H1 between the first reference plate 5 and the right edge of the first end 411 is less than the minimum standard distance W1 between the left edge of the widest point of the brake pedal 1 in the y-direction and the foot pedal 2. Preferably, H1 is 85%-98% of W1, and more preferably, H1 is 94%-96% of W1. The y-direction distance H2 between the second reference plate 6 and the end face of the brake pedal extension plate 7 is less than the minimum standard distance W2 between the right edge of the widest point of the brake pedal 1 in the y-direction and the central channel 14. Preferably, H2 is 90%-99% of W2, and more preferably, H2 is 95%-98% of W2. The distance H3 between the tangent of the brake pedal 1 foot surface with the maximum curvature and the bottom surface of the brake pedal extension plate 7 is less than the minimum standard distance W4 between the brake pedal 1 and the accelerator pedal 3. When the plane containing the top surface of the brake pedal extension plate 7 is coplanar with the tangent of the brake pedal 1 foot surface with the maximum curvature, the distance H3 between the tangent of the brake pedal 1 foot surface with the maximum curvature and the bottom surface of the brake pedal extension plate 7 is the thickness between the top and bottom surfaces of the brake pedal extension plate 7. At this time, the thickness H3 between the top and bottom surfaces of the brake pedal extension plate 7 is less than the minimum standard distance W4 between the brake pedal 1 and the accelerator pedal 3. Preferably, H3 is 80%-98% of W4, and more preferably, H3 is 85%-95% of W4.

[0055] like Figure 1 and Figure 2 As shown, defining the standard distance between the following pedals can improve user experience and driving safety:

[0056] W806.1: specifies the minimum distance between the brake pedal 1 and the left footrest 2, preventing the brake pedal 1 from being too close to the footrest 2, which would cause a small spacing between the driver's right leg and left leg when the driver depresses the brake pedal 1 and result in user discomfort;

[0057] W807.1: specifies the minimum distance and maximum distance between the brake pedal 1 and the center tunnel 14, which indirectly specifies the distance between the brake pedal 1 and the accelerator pedal 3, preventing user discomfort when switching between different pedals caused by an excessively large distance between the two pedals;

[0058] L52: specifies the minimum distance and maximum distance between the foot surfaces of the brake pedal 1 and the accelerator pedal 3, that is, specifies the foot height difference when moving from the brake pedal 1 to the accelerator pedal 3, preventing accidental pressing caused by an excessively small distance between the two foot surfaces which leads to potential safety hazards, or user discomfort when switching between different pedals caused by an excessively large distance.

[0059] Direct measurement of the above distances is difficult. By providing the first reference plate 5, the second reference plate 6 and the brake pedal extension plate 7, the measurement of the distance between the brake pedal 1 and the footrest 2 is converted into the measurement of the distance between the brake pedal 1 and the first reference plate 5, the measurement of the distance between the brake pedal 1 and the center tunnel 14 is converted into the measurement of the distance between the brake pedal 1 and the second reference plate 6, and the measurement of the distance between the brake pedal 1 and the accelerator pedal 3 is converted into the measurement of the distance between the brake pedal extension plate 7 and the accelerator pedal 3, which optimizes the measurement process.

[0060] It is qualified as long as the actual distance between each pedal meets the standard distance requirement, and it is not necessary to measure the specific value of the actual distance between each pedal. Therefore, a measuring block 12 may also be provided. The measuring block 12 is used to measure the gap between the brake pedal 1 and the first reference plate 5, the gap between the brake pedal 1 and the second reference plate 6, and the gap between the brake pedal extension plate 7 and the accelerator pedal 3. After inserting the measuring block 12 into the corresponding gap, the measurement result can be quickly judged according to the insertion condition of the measuring block 12 in the gap. The thickness of said measuring block 12 includes A1, A2, A3, A4 and A5, wherein,

[0061] A1 = the minimum standard distance W1 between the footrest 2 and the brake pedal 1 minus the y-direction distance H1 between the first reference plate 5 and the right edge of the first end 411;

[0062] A2 = the minimum standard distance W2 between the brake pedal 1 and the center tunnel 14 minus the y-direction distance H2 between the second reference plate 6 and the upper contour block of the center tunnel 14;

[0063] A3 = the maximum standard distance W3 between the brake pedal 1 and the center tunnel 14 minus the y-direction distance H2 between the second reference plate 6 and the upper contour block of the center tunnel 14;

[0064] A4 = Minimum standard distance between brake pedal 1 and accelerator pedal 3; W4 - Thickness H3 between the top and bottom surfaces of brake pedal extension plate 7;

[0065] A5 = Maximum standard distance between brake pedal 1 and accelerator pedal 3; W5 - Thickness H3 between the top and bottom surfaces of brake pedal extension plate 7.

[0066] The measuring block 12 can be configured as a separate measuring block 12 corresponding to each thickness, or it can be configured as a stepped shape with 5 steps. The thickness of each step corresponds to the required thicknesses A1, A2, A3, A4, and A5 of the measuring block 12. This integrates all thicknesses onto a single measuring block 12, eliminating the need to replace the measuring block 12 when measuring different gaps, and also facilitating storage. Preferably, the measuring block 12 can also be configured as a 4-step block, with the distance between the opposite faces of the first and last steps of the measuring block 12 set to the maximum value among A1, A2, A3, A4, and A5. When A1, A2, A3, A4, and A5 have the same value, the number of steps can be reduced accordingly, with one step corresponding to the same thickness.

[0067] To facilitate understanding of the present invention, the following uses a certain vehicle model as an example to illustrate the use and measurement process of the tool. The standard for defining the distance between each pedal in this vehicle model is shown in Table 1.

[0068] Table 1 Standard Distance for Car Pedals

[0069] standard ≥164mm 156±5mm 47.2±10mm

[0070] When using this tool, such as Figure 4 As shown, the base 4 is placed on the cab floor. The outer contour of the base 4 is modeled after the contours of the foot pedal 2, seat crossbeam 15, door sill 13, and the connection between the central tunnel 14 and the floor. That is, the outer contour of the base 4 is basically the same as the outer contour of the corresponding position on the cab floor. The first end 411 abuts against the foot pedal 2, the second end 412 abuts against the seat crossbeam 15, the third end 413 abuts against the door sill 13, and the fourth end 421 and the end face of the brake pedal extension plate 7 abut against the central tunnel 14, so that the tool is locked on the cab floor, thereby fixing the positions of the first reference plate 5, the second reference plate 6, and the brake pedal extension plate 7, preventing displacement and improving the accuracy of measurement.

[0071] As shown in Table 1, the minimum standard distance W1 between the left edge of the widest point in the y-direction of brake pedal 1 and foot pedal 2 is 164mm. The minimum standard distance W2 and the maximum standard distance W3 between the right edge of the widest point in the y-direction of brake pedal 1 and the central channel 14 are 151mm and 161mm, respectively. The minimum standard distance W4 and the maximum standard distance W5 between brake pedal 1 and accelerator pedal 3 are 37.2mm and 57.2mm, respectively. Therefore, when setting the y-direction distance H1 between the first reference plate 5 and the right edge of the first end 411, the y-direction distance H2 between the second reference plate 6 and the end face of the brake pedal extension plate 7, and the thickness H3 between the top and bottom surfaces of the brake pedal extension plate 7, it is necessary to ensure that H1 < 164mm, H2 < 151mm, and H3 < 37.2mm. Preferably, H1 = 157mm, H2 = 148mm, and H3 = 24.2mm. Then, the gap between the brake pedal 1 and the first reference plate 5 is acceptable if it is greater than 7mm, the gap between the brake pedal 1 and the second reference plate 6 is acceptable if it is between 3-13mm, and the gap between the brake pedal extension plate 7 and the accelerator pedal 3 is acceptable if it is between 3-23mm. Therefore, the thickness of the corresponding measuring block 12 needs to be set as follows:

[0072] A1 = Minimum standard distance between foot pedal 2 and brake pedal 1 W1 - Y-direction distance between the first reference plate 5 and the right edge of the first end 411 H1 = 164 - 157 = 7mm;

[0073] A2 = Minimum standard distance W2 between brake pedal 1 and central channel 14 - Y-direction distance H2 between second reference plate 6 and upper contour block of central channel 14 = 151 - 148 = 3mm;

[0074] A3 = Maximum standard distance W3 between brake pedal 1 and central channel 14 - Y-direction distance H2 between second reference plate 6 and upper contour block of central channel 14 = 161 - 148 = 13mm;

[0075] A4 = Minimum standard distance between brake pedal 1 and accelerator pedal 3; W4 - Thickness between the top and bottom surfaces of brake pedal extension plate 7; H3 = 37.2 - 34.2 = 3mm;

[0076] A5 = Maximum standard distance between brake pedal 1 and accelerator pedal 3; W5 - Thickness between the top and bottom surfaces of brake pedal extension plate 7; H3 = 57.2 - 34.2 = 23 mm.

[0077] like Figure 5 As shown, the thickness of each step of the measuring block 12, from low to high, includes at least 3mm, 7mm, 13mm, and 23mm. Of course, the measuring block 12 can also be further integrated with the thicknesses required by other vehicle models, including more steps. For example... Figure 6As shown, the measuring block 12 can also be configured with three steps, with thicknesses of 3mm, 7mm, and 13mm respectively from low to high. The distance between the opposite surfaces of the first and last steps of the measuring block 12 is set to 23mm. The steps of the measuring block 12 are marked with the corresponding thickness values ​​for each step, making it easier to select the required step during use.

[0078] When testing the distance between brake pedal 1 and foot pedal 2, insert a 7mm thick portion of measuring block 12 into the gap between brake pedal 1 and the first reference plate 5. If it can be inserted, the gap between brake pedal 1 and the first reference plate 5 is greater than 7mm, and the distance between brake pedal 1 and foot pedal 2 is acceptable; otherwise, it is unacceptable. When testing the distance between brake pedal 1 and the central channel 14, insert 3mm and 13mm thick portions of measuring block 12 into the gap between brake pedal 1 and the second reference plate 6, respectively. If the 3mm portion can be inserted but the 13mm portion cannot, the distance between brake pedal 1 and the central channel 14 is acceptable; otherwise, if the 3mm portion cannot be inserted or the 13mm portion can be inserted, it is unacceptable. When it is necessary to test the distance between the brake pedal 1 and the accelerator pedal 3, the 3mm and 23mm thick portions of the measuring block 12 are inserted into the gap between the brake pedal extension plate 7 and the accelerator pedal 3, respectively. If the 3mm portion can be inserted into the gap but the 23mm portion cannot, the distance between the brake pedal 1 and the accelerator pedal 3 is considered acceptable. Conversely, if the 3mm portion cannot be inserted or the 23mm portion can be inserted, the distance is considered unacceptable. The measuring block 12 allows for a quick and intuitive assessment of the gap size, making the operation convenient and efficient.

[0079] The end face of the brake pedal extension plate 7 extends to a foot surface lower than that of the accelerator pedal 3. This not only increases the contact area between the brake pedal extension plate 7 and the central channel 14, making the tool positioning more secure, but also allows the distance between the accelerator pedal 3 and the central channel 14 to be determined by measuring the gap between the inner side of the end face of the brake pedal extension plate 7 and the accelerator pedal 3. This prevents the accelerator pedal 3 from being too close to the vehicle's central channel 14, thus avoiding interference between the driver and the central channel 14 when the driver presses the accelerator pedal 3.

[0080] To facilitate handling and removal of the tool, a first reinforcing plate 8 can be installed on the base 4. The first reinforcing plate 8 and the reference plate are located on the same side of the base 4. Both ends of the first reinforcing plate 8 are fixedly connected to the first contouring portion 41 and the second contouring portion 42, respectively, connecting the two sides of the L-shape of the base 4. A handle 9 is provided on the first reinforcing plate 8 for easy tool handling. To facilitate installation and improve the tool's strength, a support plate 10 perpendicular to the second contouring portion 42 is provided on the second contouring portion 42. The support plate 10 and the reference plate are located on the same side of the base 4, and the brake pedal extension plate 7 is fixed to the support plate 10. A second reinforcing plate 11 perpendicular to the second contouring portion 42 is provided on the second contouring portion 42. The second reinforcing plate 11 and the reference plate are located on the same side of the base 4, and the ends of the first base 4, the second base 4, and the support plate 10 are fixed to the second reinforcing plate 11. The first base 4, the second base 4, and the support plate 10 can be directly fixed to the second reinforcing plate 11 using screws or welding, and the brake pedal extension plate 7 can be fixed to the support plate 10. To reduce the weight of the tool, the top surfaces of the first reference plate 5, the second reference plate 6, and the support plate 10 can be sloped to remove some material. Different vehicle models have different tool configurations, and markings can be made on the tool to easily identify the vehicle model to which it is applicable.

[0087] This invention also provides a method for manufacturing a car pedal spacing measuring tool, which is manufactured based on a 3D digital model of the car pedal spacing measuring tool, and includes the following steps:

[0088] S1. Based on the 3D digital model of the base 4, the base 4 is machined or stamped out, and the first reference plate 5, the second reference plate 6 and the brake pedal extension plate 7 are machined out.

[0091] Based on the cross-sectional shape of the vehicle's cab floor, the floor surface is cut into L-shapes with the front, rear, left, and right abutment ends matching the contours of the parts requiring contouring, such as the foot pedal 2, seat crossbeam 15, door sill 13, and center tunnel 14. This yields the cross-sectional shape of the base 4. Stretching the cross-sectional shape of the base 4 to a suitable thickness creates the 3D model of the base 4. According to the standard for pedal spacing, appropriate values ​​H1, H2, and H3 are set. Based on H1 and H2, measurement reference surfaces for the first reference plate 5 and the second reference plate 6, namely the first plane and the fourth plane, are created.

Based on H3, the third plane, the measurement reference surface for the brake pedal extension plate 7, is created. The installation position of the brake pedal extension plate 7 is marked on the second reference plate 6. Based on the 3D model of the base 4, the base 4 is machined or stamped out. After the first reference plate 5, the second reference plate 6 and the brake pedal extension plate 7 are machined out, the first reference plate 5, the second reference plate 6 and the brake pedal extension plate 7 can be vertically installed in a position consistent with the model, which ensures the accuracy of tool making and thus ensures the accuracy of measurement.
