[0002] In the existing mechanical processing industry, the surface of the machined parts needs to meet certain dimensional standards, and the corresponding measurement methods must be used to determine whether they meet the standards. A simple measurement method often used in the industry is to select the opposite surface of the workpiece to be measured as the reference surface for measurement, and then use measuring tools such as vernier calipers and micrometers to manually measure the height of different positions on the surface to be measured.

[0003] At present, the existing product flatness measurement equipment needs to place the product on the measuring table and then measure the flatness of the product. The levelness of the measuring table has a very important impact on the accuracy of the measurement of the product to be measured. If the levelness of the measuring table itself is poor, the flatness of the product cannot be accurately measured. The current measuring table is just a simple table, which cannot be adjusted according to the levelness of the ground where it is placed, resulting in poor accuracy in measuring the flatness of the product. For this reason, we propose a flatness meter. Utility Model Content

The latch 29 cooperates with the socket 30. A sleeve block 11 is installed on the outer side of the threaded rod 6. Two support rods 12 are fixedly installed on the top of the sleeve block 11. One end of the support rod 12 extends to the outer side of the top of the installation cavity 5 and is fixedly installed with a connecting plate 13. A plurality of slide rods 14 are fixedly installed on the top of the connecting plate 13. A plurality of slide grooves 15 are provided at the bottom of one side of the top plate 3. The slide rods 14 are slidably connected with the slide grooves 15. A bubble level 20 is fixedly installed on one side of the top plate 3. The function of the latch 29 and the socket 30 is to limit the handle turntable 10 after the rotation and adjustment of the handle turntable 10 is completed, so as to avoid the situation in which the handle turntable 10 is rotated by mistake during the measurement process, causing the threaded rod 6 to rotate and causing the horizontality of the top plate 3 to deviate. By arranging moving wheels at the bottom of the bottom plate 1, it is convenient to move the equipment.

[0020] A controller is arranged on one side of the top of the bottom plate 1 .

[0021] A through slot 16 is provided in the middle of the top plate 3, and a horizontal plate 17 is movably installed inside the through slot 16. Rotating slots 18 are provided inside the top plate 3 and on both sides of the through slot 16. A swivel head 19 is fixedly installed on both sides of the horizontal plate 17, and the swivel head 19 is movably connected to the rotating slot 18.

[0023] In summary, when the flatness measuring device is used, the device is moved to the use site by the moving wheel, and then the bubble level 20 is observed to check whether the top plate 3 is in a horizontal state. When the top plate 3 is not in a horizontal state, the latch 29 is pulled out and then the handle turntable 10 is rotated to rotate the shaft 8 and the active bevel gear 9. The active bevel gear 9 is engaged with the driven bevel gear 7 to drive the threaded rod 6 to rotate, which can drive the sleeve block 11 and the support rod 12 to move through the thread. The support rod 12 can be driven to rise or fall by rotating the handle turntable 10 forward and backward, thereby adjusting the horizontal state of the top plate 3. Observe the bubble level 20 to ensure that the top plate 3 is adjusted to a horizontal state, then insert the pin 29 into the socket 30 to limit the handle turntable 10. When the top plate 3 is adjusted to a horizontal state, the horizontal plate 17 will be leveled according to the gravity of the falling cone 22. When the horizontal plate 17 is level, place the product to be measured on the measuring plate 23 and then turn on the first telescopic rod 25 through the controller to drive the second telescopic rod 26 to move downward, so that the measuring head 28 can be moved down to above the surface of the product to be measured. Then, turn on the second telescopic rod 26 to drive the micrometer 27 and the measuring head 28 to move horizontally, and measure the product while moving.
