[0023] Reference Figure 1-Figure 7 The utility model discloses a pallet and a high-precision positioning mechanism for a pallet, comprising a high-precision positioning mechanism 1 and a pallet 2 which can be fixed and positioned thereon with high precision. When the pallet 2 is fixed on the high-precision positioning mechanism 1, the high-precision positioning mechanism 1 can be fully covered. Such a design is beneficial to the daily processing and maintenance of CNC machine tools.

[0024] Reference Figure 1-Figure 7 In the present embodiment, the tray 2 is firstly sleeved on the two guide posts 104 through its two guide bushings 21 to complete a guiding function. Then, the bottom of the main body of the tray 2 is directly inserted into the four positioning clamping components 102 through four positioning pins 22 to achieve positioning. Then, air is evacuated through the external air circuit, so that the four positioning pins 22 fixed on the tray 2 can be firmly fixed on the four positioning clamping components 102, thereby completing the high-precision positioning operation. In the present embodiment, the above-mentioned positioning clamping component 102 has a clamping channel (not marked in the figure), and the above-mentioned clamping channel (not marked in the figure) is used to position the positioning pins 22.

[0025] Reference Figure 1-Figure 7The high-precision positioning mechanism includes a connecting and fixing plate 10 for fixing on the CNC indexing plate. The middle position of the main body of the connecting and fixing plate 10 is respectively provided with four first mounting positions 101.

Of course, the positioning and clamping components 102 are also symmetrical with respect to the center line of the connecting and fixing plate 10. The above design can ensure the positioning accuracy when positioning the pallet 2, because, for the processing operation of the CNC machine tool, the accurate positioning of the fixture is the prerequisite for the processing quality; since, this embodiment adopts pneumatic fixation, a through hole 1011 is opened at the bottom of the above-mentioned first mounting position 101, and the above-mentioned through hole 1011 is located in the middle of the first mounting position 101, and the air inlet of the above-mentioned positioning clamping assembly 102 is directly connected to the through hole 1011.

Of course, the two guide posts 104 are also symmetrical with the center line of the connecting and fixing plate 10; the pallet 2 is first inserted into the guide posts 104 through the guide bushings 21 to complete a guiding operation; since the caliber of the guide bushings 21 is larger than the caliber of the guide posts 104, an arc-shaped step groove 105 is also provided at the joint between the connecting and fixing plate 10 and the fixing countersunk holes 103, and the end of the guide bushings 21 can abut against the arc-shaped step groove 105.
