[0026] Example 1

[0027] Please see the appendix Figures 1-5 This utility model discloses a high-precision flat sheet tooling with high flatness, including a mounting base 1, a positioning mounting mechanism 2, an adjusting foot 3, and a locking mechanism 4, wherein:

[0028] The positioning and mounting mechanism 2 includes a positioning frame 21 that can rotate back and forth and is disposed in the middle of the mounting base 1. The positioning frame 21 is rotatably connected to the mounting base 1.

[0029] The adjustable feet 3 include multiple feet 31 located on the left and right sides of the bottom of the mounting base 1. The feet 31 are connected to the mounting base 1 via liftable lifting seats 341.

[0030] The locking mechanism 4 is located on the upper end of the mounting base 1 and is used to lock and restrict the rotation of the positioning frame 21.

[0031] Please refer to the appendix. Figure 7 A connecting platform 12 is installed at the upper middle position of the mounting base 1, and a mounting plate 23 is symmetrically installed at the lower middle position of the positioning frame 21. A first rotating shaft 24 is installed between the mounting plates 23. The first rotating shaft 24 passes through the connecting platform 12 and is rotatably connected to the connecting platform 12.

[0032] Specifically, the positioning frame 21 can be rotated back and forth on the mounting base 1 by the first rotation to achieve leveling in the front and back directions.

[0033] Please refer to the appendix. Figure 2 , Figure 3 , Figure 4 , Figure 5 The adjustable foot 3 also includes a slide 32 movably connected to the bottom of the mounting base 1. The slide 32 is fixedly connected to the lifting base 341. A screw 34 is installed at the bottom of the lifting base 341. A first fixing plate 35 and a second fixing plate 36 are symmetrically installed on the upper end of the foot base 31. Both the first fixing plate 35 and the second fixing plate 36 are provided with screw holes 351 that are threadedly connected to the screw 34. An operating disc 33 is installed at the bottom of the screw 34.

[0034] Specifically, rotating the control panel 33 can drive the screw 34 to rise and fall, and the screw 34 can drive the lifting seat 341 to rise and fall. Adjusting the height of the left and right ends of the mounting seat 1 by adjusting the feet 3 at different positions can adjust the height of the mounting seat 1, thereby leveling the mounting seat 1.

[0035] Furthermore, a second rotating shaft 322 is installed at the bottom of the slide table 32, the lifting seat 341 is rotatably connected to the second rotating shaft 322, the base 31 is provided with a through operating port 311 in the middle, the screw 34 extends into the operating port 311, and the operating plate 33 is located inside the operating port 311.

[0036] Specifically, the design of the operating port 311 allows staff to easily rotate the operating panel 33.

[0037] Furthermore, the upper end of the slide table 32 is symmetrically equipped with sliders 321 with a T-shaped cross-section, and the bottom of the mounting base 1 is symmetrically provided with multiple sliding grooves 11. The sliders 321 and the sliding grooves 11 are slidably connected. The sliders 321 and the sliding grooves 11 can move and compensate when the mounting base 1 moves left and right, while preventing the slide table 32 from separating from the mounting base 1.

[0038] Example 2

[0039] Based on the above embodiment one, please refer to the appendix. Figure 6 The locking mechanism 4 includes locking cylinders 41 symmetrically mounted on the upper end of the mounting base 1 facing the positioning frame 21, and a locking plate 42 that cooperates with the positioning frame 21 is installed at the output end of the locking cylinder 41.

[0040] Furthermore, the locking cylinder 41 is installed in the middle position parallel to the axis of the first rotating shaft 24, and the positioning frame 21 is symmetrically equipped with locking frames 22 at both ends. The locking plate 42 is movably connected to and cooperates with the locking frames 22.

[0041] In this embodiment, after the positioning frame 21 is rotated back and forth through the first rotating shaft 24 to achieve leveling, the position of the positioning frame 21 is kept unchanged. Then, the locking cylinder 41 drives the locking plate 42 to press against the locking frame 22, so that the positioning frame 21 remains stable and will not continue to rotate.

[0042] The working principle and usage process of this utility model are as follows: When making left and right adjustments on an uneven work site, first measure the flatness of the mounting base 1 in the left and right directions using a level. Adjust the height of the mounting base 1 on both sides according to the data of the level. When it is necessary to adjust the height of one side, rotate the operating plate 33 inside the adjusting foot 3 on one side. The operating plate 33 drives the screw 34 to rotate. When the screw 34 rotates, it drives the screw 34 to rise or fall through the screw hole 351. The rise or fall can be controlled by the rotation direction of the screw 34. The screw 34 drives the lifting seat 341 to rise or fall. The lifting seat 341 drives the slide table 32 to rise or fall. When the slide table 32 rises or falls, the mounting base 1 on that side rises or falls to achieve left and right leveling.

[0043] During the front-to-back adjustment, the flatness of the mounting base 1 in the front-to-back direction is measured using a level. Then, based on the data from the level, the positioning frame 21 is rotated directly. The positioning frame 21 rotates in the front-to-back direction via the first rotating shaft 24 to achieve leveling. After the positioning frame 21 is leveled by rotating back and forth via the first rotating shaft 24, the position of the positioning frame 21 is kept unchanged. Then, the locking cylinder 41 drives the locking plate 42 to press against the locking frame 22, so that the positioning frame 21 remains stable and will not continue to rotate, thus completing the leveling operation. Finally, the workpiece can be fixedly installed through the positioning frame 21. At this time, the workpiece is flat and can be processed.
