[0028] Embodiment 1:

[0029] As shown in the attached Figure 1 to the attached Figure 6 as follows:

[0030] The utility model provides a bearing tooling for a magnetic levitation turbine vacuum pump, including a bearing seat 1; at the front and rear ends of the top of the bearing seat 1, an adjusting seat 101 is fixedly connected respectively. The two adjusting seats 101 are symmetrically designed, and at the left and right sides of the top of each adjusting seat 101, a threaded hole is provided respectively. Above each adjusting seat 101, a bearing platform 102 is arranged. At the left and right sides of the bottom of the bearing platform 102, a threaded rod 103 is symmetrically rotatably connected. The four threaded rods 103 are respectively rotatably connected in the threaded holes provided in the two adjusting seats 101. On the top of the two bearing platforms 102, a magnetic levitation turbine vacuum pump body 3 is placed. After rotating and adjusting the four threaded rods 103 and the threaded holes of the two adjusting seats 101, the height of the bearing platform 102 can be adjusted, so as to lift and lower the magnetic levitation turbine vacuum pump body 3.

[0031] Among them, at the middle position of the top of the bearing seat 1, an adjusting frame 2 is fixedly connected. At the left and right sides of the inside of the adjusting frame 2, a clamping plate 202 is slidably connected respectively. The two clamping plates 202 are symmetrically designed, and at the inner sides of the two clamping plates 202, clamping grooves are provided respectively. At the two side positions of the magnetic levitation turbine vacuum pump body 3, the two clamping plates 202 are clamped and fixed. At the lower side positions of the sides of the two clamping plates 202, threaded holes are provided respectively, and the threaded holes of the two clamping plates 202 are symmetrically designed. Inside the adjusting frame 2, a bidirectional screw rod 201 is rotatably connected. At the left and right sides of the bidirectional screw rod 201, they are respectively located in the threaded holes of the two clamping plates 202.

[0032] Among them, at the four corners of the bottom of the bearing seat 1, a leveling seat 104 is arranged respectively. At the bottom of each leveling seat 104, a support leg with adjustable height and a universal wheel are provided. When the universal wheel at the bottom of the leveling seat 104 is lower than the support leg, the bearing seat 1 can move its position through the universal wheel of the leveling seat 104.

[0033] When in use:

[0034] Place the magnetic levitation turbine vacuum pump body 3 on the top of the two bearing platforms 102. Next, rotate the bidirectional screw rod 201. Through the cooperation of the bidirectional screw rod 201 and the threaded holes of the two clamping plates 202, the two clamping plates 202 slide in the inner position of the adjusting frame 2 in opposite directions. When the two clamping plates 202 approach, they will fit against the left and right sides of the magnetic levitation turbine vacuum pump body 3, limit the magnetic levitation turbine vacuum pump body 3 at the top position of the bearing seat 1, and ensure that the installation and fixing position of the magnetic levitation turbine vacuum pump body 3 is centered and clamped and fixed.

[0035] After placing the bearing seat 1 and leveling it, the bearing seat 1 is leveled by the support legs that adjust the height of the bottom position of the leveling seat 104, which facilitates the planar leveling of the magnetic levitation turbine vacuum pump body 3 placed above the two support platforms 102.
