Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0020] like Figure 1 、 Figure 2 and Figure 3 As shown, the utility model is an air-floating support platform with an automatic centering function, comprising a support platform 1 and an air-floating turntable 2, wherein the air-floating turntable 2 is placed on the support platform 1, and a transverse clamping rod 5 for transversely clamping the air-floating turntable 2 is provided on the support platform 1, and a strip-shaped opening is provided on the transverse clamping rod 5, and an adjustment block 6 is slidably installed in the strip-shaped opening, and an L-shaped plate 7 is installed on one side surface of the adjustment block 6, and an extrusion portion 16 is obliquely provided at one end of the L-shaped plate 7, and the extrusion portion 16 is arranged to contact the end surface of the base on the air-floating turntable 2, an end plate 3 is installed at one end of the support platform 1, and a cover body 4 is provided on the outside of the support platform 1.

[0021] In this embodiment, a screw rod 17 hole is provided on the adjustment block 6, bearings are embedded in both ends of the strip-shaped opening, screw rods 17 are threadedly connected in the opposite screw rod 17 holes, both ends of the screw rod 17 are installed in the inner ring of the bearing, and one end of the transverse clamping rod 5 is installed with a motor 8 connected to the screw rod 17.

[0022] In this embodiment, a plurality of positioning grooves are provided on the surface of the support platform 1, and a plurality of positioning blocks are installed on one end face of the transverse clamping rod 5 facing the support platform 1. The positioning blocks are all slidably set in the positioning grooves. Cylinders 9 are installed at both ends of the support platform 1, and the piston rods of the cylinders 9 are all installed on the transverse clamping rod 5.

[0023] In this embodiment, first slide grooves 15 are horizontally provided on both sides of the cover body 4, and first slide bars 10 are protruded on both sides of the support platform 1. The first slide bars 10 are slidably set in the first slide grooves 15, so that the cover body can only be stable along the first slide bars, and the friction contact between the first slide bars and the first slide grooves can position the cover body after movement.

[0024] In this embodiment, second sliding grooves are provided on both sides of the strip-shaped opening, and both sides of the adjustment block 6 protrude to form second sliders, which are slidably arranged in the second sliding grooves, so that the adjustment block can only move back and forth along the second sliding grooves, thereby increasing stability.

[0025] In this embodiment, a "U"-shaped avoidance groove 12 is formed on one side of the cover body 4, and the end plate 3 protrudes toward one end of the avoidance groove 12 to form a sealing portion 11, and the end of the support platform 1 away from the end plate 3 protrudes to form a limiting portion 14. The cover body can pass smoothly from the outside of the motor through the avoidance groove to avoid being blocked by the motor. After moving to a certain distance, the inner side surface of the cover body can contact the limiting portion, and the sealing portion on the end plate just covers the opening at one end of the avoidance groove.

[0026] When in use, the air float turntable can be placed directly on the support table, and the cylinder is started to extend the piston rod of the cylinder. The extension of the piston rod pushes the transverse clamping rod, so that the transverse clamping rod moves inward along the positioning groove, thereby moving the air float turntable to the middle. After it is horizontally centered, the motor can be started. The start of the motor drives the screw rod, and the rotation of the screw rod drives the adjusting block, so that the adjusting block moves inward along the second slide groove. The movement of the adjusting block drives the L-shaped plate until the extrusion part of the L-shaped plate is against the end face of the air float turntable. Since the extrusion part is inclined, it can press air float turntables of different heights, which increases adaptability, and can apply a downward pressure to the air float turntable through the extrusion part to increase the stability of the installation.

[0027] Among them, when the air-floating turntable is not in use, the cover body can move along the first slide bar toward the end plate until one end face of the cover body collides with the end plate, and the other end of the cover body collides with the limit part. The air-floating turntable can be completely covered by the cover body, end plate, limit part and support platform, avoiding contact with external dust and water vapor, and increasing safety in subsequent use.

[0028] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that do not require creative effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
