Wherein, the reference flat plate 2 rotates and assembles on base 1, in order to realize the rotation of reference flat plate 2, in this embodiment, installs gear motor 4 in the central point department of base 1, and gear motor 4's output shaft and reference flat plate 2 transmission are connected, so, when gear motor rotated, reference flat plate 2 rotated along with it. In practical application, the speed reducing motor is small in specification and low in rotating speed. In order to make the reference flat plate 2 more stable when rotating, as shown in fig. 3, a guide ring groove 11 is arranged on the base 1, three guide posts 12 are arranged on the lower surface of the reference flat plate 2, the size of the three guide posts 12 is matched with the groove width of the guide ring groove 11, the three guide posts 12 are uniformly distributed along the circumferential direction of the reference flat plate 2, the bottom ends of the three guide posts 12 extend into the guide ring groove 11, and when the reference flat plate 2 rotates, each guide post 12 rotates circumferentially in the guide ring groove 11 around the output shaft of the speed reduction motor. The guide post 12 supports and guides the reference plate 2, and prevents the reference plate 2 from shifting during rotation.
The reference flat plate 2 is parallel to the base 1 supported by the output shaft of the reduction motor and is arranged at intervals in the up-down direction, the reference flat plate 2 is a circular plate, and the upper surface of the reference flat plate 2 is a reference surface for placing a part to be measured. As shown in fig. 2, six mounting long holes 3 are provided in the reference plate 2, the mounting long holes 3 are evenly distributed in the circumferential direction of the reference plate 2, and each mounting long hole 3 extends to the end of the reference plate 2 in the radial direction of the reference plate 2 and penetrates the reference plate 2 up and down.
The displacement sensors 5 are provided with six and correspond to the mounting long holes 3 one by one, each displacement sensor 5 is adjustably assembled in the corresponding mounting long hole 3 along the radial position of the reference flat plate 2, the displacement sensors 5 can rotate along with the reference flat plate 2, and the measuring end of each displacement sensor 5 upwards extends out of the mounting long hole 3 to be used for being in contact with a part to be measured.
The part of the output shaft of the speed reducing motor 4 below the reference flat plate 2 is fixedly connected with a rotary plate 7, electric push rods 6 are arranged at positions corresponding to the displacement sensors 5 on the rotary plate 7, and the moving ends of the electric push rods 6 are connected with the corresponding displacement sensors 5 to push the displacement sensors 5 to move in the corresponding mounting long holes 3. Since the turntable 7 is also fixed to the output shaft of the reduction motor, the turntable 7 rotates together with the reference plate 2, that is, the electric push rod 6 rotates together with the displacement sensor 5. The guide post 12 passes through the turntable 7.
In order to avoid the base 1 from slipping during measurement to affect the accuracy of measurement, the bottom of the base 1 is provided with a non-slip mat 14.
The communication display component comprises a box body 8 fixed on the base 1, a display screen 9 and a control panel 10 which are arranged on the box body 8, and a data processor arranged in the box body 8. The data processor is connected with the display screen 9, the control panel 10 and each displacement sensor 5 through a wire 13, the control panel 10 is provided with a one-key measuring button and a reset button, the one-key measuring button is used for realizing simultaneous detection of each displacement sensor 5, and the reset button is used for realizing reset of each displacement sensor.

When the part flatness detection tool is used, a part to be detected is placed on the reference flat plate 2, the part to be detected presses the measuring end of the displacement sensor 5, and the measuring end is clicked to measure, during measurement, displacement electric signals compressed by the contact of each displacement sensor 5 and the plane of the part to be detected are transmitted to the data processor through the wires, and the data processor displays a processing result on the display screen 9. When different positions on the plane of the part to be measured need to be measured, the reference flat plate 2 is rotated, so that the position of the displacement sensor 5 on the same circumference is adjusted along with the rotation of the reference flat plate 2, or the displacement sensor 5 is moved along the radial direction of the reference flat plate to adjust the displacement sensor 5 to the circumferences with different diameters, and at the moment, all electric push rods need to synchronously act; of course, the electric push rods may also be operated asynchronously, and the displacement sensors 5 are located on the circumferences with different diameters when moving to different positions. When each displacement sensor 5 moves in place, a reset button needs to be clicked first, and then a one-key measurement button needs to be clicked again, so that more positions on the plane of the part to be detected can be detected. The displacement sensor in this embodiment is the prior art, and can measure the distance in the direction perpendicular to the reference flat plate from points in different areas on the plane of the part to be measured, and calculate the difference between the maximum value and the minimum value, which is the flatness of the part to be measured. In the actual measurement process, if the measuring ends of all the displacement sensors are squeezed to be level with the upper surface of the reference flat plate, the flatness of the part to be measured can be considered to be 0.
The part flatness detection tool can measure a plurality of positions of a part to be detected, so that the part flatness detection accuracy is improved, meanwhile, the part flatness can be accurately detected through the displacement sensor, and the later-stage processing of some unqualified parts is facilitated.
In other embodiments, the rotation angle of the reference plate can be controlled more easily, and the rotation angle of the reference plate is prevented from being too large.
In other embodiments, the base may not be provided with a guide ring groove, and in this case, the reference plate is supported against the output shaft of the speed reduction motor without being offset without being provided with a guide post.
