The tooling has a simple structure, low manufacturing cost, and long service life. At the same time, due to its efficient and accurate measurement characteristics, it can greatly improve production efficiency and reduce production costs.
[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

This design enables the measuring frame to fit the boss of the motor housing more closely, thereby improving the adaptability and stability between the tooling and the motor housing. Moreover, since the arc surface is adapted to the outer shape of the boss of the motor housing, the measurement error caused by the mismatch between the tooling and the motor housing can be reduced, which helps to improve the accuracy and reliability of flatness detection. In addition, the adaptive arc design allows the operator to more conveniently place the U-shaped measuring frame on the motor housing, thereby reducing the time for adjustment and positioning.

[0030] The principles and features of the present invention are described below in conjunction with examples. The examples are only used to explain the present invention and are not used to limit the scope of the present invention. Specific embodiment one:
[0032] like Figure 1As shown, a flatness detection tool includes a U-shaped measuring frame 1, a first measuring table 2 and a second measuring table 3, wherein the first measuring table 2 and the second measuring table 3 are respectively installed at two ends of the U-shaped measuring frame 1, and the measuring pointer of the first measuring table 2 and the measuring pointer of the first measuring table 2 are both vertically downward.
[0033] like Figure 2 As shown, the flatness detection tooling also includes a proofreading base plate 4, a first proofreading block 5 and a second proofreading block 6. The U-shaped measuring frame 1 is arranged above the proofreading base plate 4, the first proofreading block 5 is arranged below the first measuring table 2, the measuring pointer of the first measuring table 2 is perpendicular to the end face of the first proofreading block 5, and the second proofreading block 6 is arranged below the second measuring table 3, and the measuring pointer of the second measuring table 3 is perpendicular to the end face of the second proofreading block 6.
[0034] A handle 7 is also provided on the top of the U-shaped measuring frame 1. By rotating the handle 7 on the tooling, multiple points can be quickly detected, thereby quickly evaluating the flatness of the plane.
[0035] The first measuring meter 2 and the second measuring meter 3 are both detachably mounted on the U-shaped measuring frame 1 through a top screw 8. When the measuring meter needs to be replaced or maintained, the measuring meter can be conveniently and quickly disassembled and installed, thereby improving the maintainability and use efficiency of the tooling.
[0036] Baffles 9 are also provided at both ends of the calibration bottom plate 4, and the baffles 9 are arranged outside the two legs of the U-shaped measuring frame 1. The baffles 9 are U-shaped structures, and the operator can rely on the baffles 9 to quickly locate and adjust the position of the measuring frame, thereby improving the calibration efficiency of the tooling.
[0037] The first calibration block 5 and the second calibration block 6 are both in contact with the inner side surfaces of the two legs of the U-shaped measuring frame 1. When the calibration block has a fixed contact point with the inner side surface of the measuring frame, the operator can place the calibration block in the same position each time during calibration, thereby reducing errors caused by human factors.
[0038] The measuring gauge is a dial gauge or a micrometer. The dial gauge and the micrometer are different in measuring range and accuracy. A suitable measuring gauge can be selected according to the specific requirements for flatness detection of the motor housing 10.
[0039] like Figure 3As shown, the upper end surface of the motor housing 10 has a circular boss protruding upward, and the detection surface is the upper surface of the circular boss. The method of using the flatness detection tool of the utility model to detect the flatness of the upper surface of the circular boss is as follows: First, adjust the probe size of the two side gauges and use the top screw 8 to install them on the U-shaped measuring frame 1. Then, place the assembled U-shaped measuring frame 1 on the proofreading base plate 4, and calibrate the dial indicator to a unified reference through the proofreading block. After the calibration is completed, place the U-shaped measuring frame 1 on the motor housing 10 to be measured to ensure that the probe of the measuring table is in contact with the surface 101 to be detected. Next, hold the handle 7 on the tool to rotate the U-shaped measuring frame 1 along the outer circle perpendicular to the detection surface, and the numbers on the measuring table will change. Finally, by comparing the starting data of the two measuring tables and observing the data changes, the flatness of the measured plane is determined. Specific embodiment 2:
[0041] like Figure 4 As shown, different from the specific embodiment 1, the inner side surfaces of the two legs of the U-shaped measuring frame 1 are designed to be arc-shaped, which is adapted to the shape of the circular boss on the motor housing 10 to be measured. During the measurement process, this design enables the two legs of the U-shaped measuring frame 1 to fit more closely to the circular boss of the motor housing 10, improving the adaptability and stability between the tooling and the motor housing 10; and because the arc surface is adapted to the shape of the circular boss, the measurement error caused by the mismatch between the tooling and the motor housing 10 can be reduced, which helps to improve the accuracy and reliability of flatness detection; in addition, the adaptive arc design allows the operator to more conveniently place the U-shaped measuring frame 1 on the motor housing 10, reducing the time for adjustment and positioning.
[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
