Description

Technical Field

[0001] This utility model relates to the field of air flotation platform technology, and more specifically to a modular assembled air flotation platform. Background Technology

[0002] Air-floating platforms are commonly used machining platform devices in modern precision machining equipment. As machine tool technology develops towards higher speed, higher efficiency, and greener operation, requirements for machining platforms have also been placed on high efficiency, low cost, and environmental friendliness. In some manufacturing scenarios, air-floating platforms are often used as worktables for precision equipment. Air flotation uses compressed air as a medium, filling the space between moving parts and guide rails to form a micron-sized air film, greatly reducing friction between them and significantly improving movement speed and positioning accuracy. For example, there is a high-precision air-floating platform with prior art publication number CN218363313U.

[0003] However, the existing technologies mentioned above still have the following problems when in use: insufficient modularity, multiple existing air flotation platform structures, cumbersome disassembly and replacement steps, resulting in low efficiency of air flotation platform structure replacement, and inability to quickly replace air flotation structures of different specifications and functions according to specific application scenarios. Based on this, the present invention provides a modular assembly air flotation platform. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a modular assembly air flotation platform to solve the problem of the air flotation platform having a complicated structure and being unable to be easily assembled and replaced.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular assembled air-bearing platform, comprising a base, X-axis air-bearing guide rails on both sides of the top of the base, a Y-axis air-bearing guide rail connected between the two X-axis air-bearing guide rails, an air-bearing block sleeved on the Y-axis air-bearing guide rail, mounting plates detachably mounted on both sides of the top of the base, each mounting plate having a moving groove machined on its top, the X-axis air-bearing guide rails being inserted into the moving grooves and connected via an insertion mechanism, the air-bearing block comprising a slider and a base, the slider having limit grooves machined on both its front and rear sides, and limit blocks fixedly mounted on both its front and rear sides of the base, the limit blocks being slidably disposed within the limit grooves and detachably connected to the slider.

[0006] In a preferred embodiment, mounting grooves adapted to the mounting plates are machined on both sides of the top of the base. The two mounting plates are respectively placed in the two mounting grooves, and the mounting grooves are used to fix the mounting plates, thereby improving the stability of the mounting plates.

[0007] In a preferred embodiment, spring pins are fixedly inserted through the inner walls of the two mounting slots on opposite sides, and slots adapted to the spring pins are machined on the opposite sides of the two mounting plates. The spring pins engage with the slots. When the operator releases and pulls the pin inside the spring pin, the pin is removed from the slot, and the mounting plate can be removed for replacement.

[0008] In a preferred embodiment, the insertion mechanism includes a lead screw rotatably disposed in a movable groove. Two nut blocks are threadedly connected to the lead screw. The threads of the two nut blocks and the lead screw have opposite directions, causing the two nut blocks to move in opposite directions. The surfaces of the two X-axis air-bearing guides are machined with slots that are adapted to the nut blocks. The nut blocks are inserted into the slots. The positions of the two nut blocks are adjusted by the lead screw, thereby improving the disassembly speed of the X-axis air-bearing guides.

[0009] In a preferred embodiment, both mounting plates have a fixed groove at their bottom that communicates with the moving groove. A servo motor is detachably connected to the fixed groove. The output shaft of the servo motor is connected to a lead screw. By driving the lead screw to rotate with the help of the servo motor, the position of the nut block can be automatically adjusted.

[0010] In a preferred embodiment, a fixing plate is fixedly provided at the bottom of each of the two servo motors. The fixing plate is detachably installed in the fixing groove and used to support and fix the servo motors, thereby facilitating quick disassembly of the servo motors for maintenance.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model supports the air-bearing block by means of the X-axis air-bearing guide rail and the Y-axis air-bearing guide rail on the base. The air-bearing block is suspended on the base and moves with frictionless and high precision. In addition, the modular design of the base, the X-axis air-bearing guide rail, the Y-axis air-bearing guide rail and the air-bearing block makes it easy to assemble, disassemble and maintain. At the same time, air-bearing platforms of different specifications and functions can be quickly built according to specific application scenarios.

[0013] 2. The X-axis air bearing guide is fixed by the installation mechanism. The positions of the two nut blocks are automatically adjusted by the servo motor and the lead screw, which can automatically fix the X-axis air bearing guide. This makes it easy for the staff to quickly disassemble the X-axis air bearing guide. The X-axis air bearing guide and the Y-axis air bearing guide are detachable. The air bearing block composed of the base and the slider can also be separated, which also makes it easy for the staff to quickly disassemble and replace the base and the slider.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Refer to the instruction manual appendix Figures 1-5 This utility model provides a modular assembled air flotation platform, including a base 1. Both sides of the top of the base 1 are provided with X-axis air flotation guide rails 11. A Y-axis air flotation guide rail 12 is connected between the two X-axis air flotation guide rails 11. An air flotation block 13 is sleeved on the Y-axis air flotation guide rail 12. Specifically, the air flotation block 13 includes a slider 131 and a base 132. In actual use, a gas delivery device is also provided to make the air flotation block 13 suspend and move.

[0024] In practical use, two X-axis air bearing guides 11 drive the Y-axis air bearing guide 12 to move in the X-axis direction on the base 1, while the air bearing block 13 moves in the Y-axis direction on the Y-axis air bearing guide 12. This enables the equipment to move flexibly. The air bearing block 13 includes a slider 131, a base 132, and a gas delivery device. The gas delivery device delivers gas into the base 132. The gas is ejected from the air bearing chambers on the slider 131 and the base 132 and diffuses in all directions. Since there are tiny gaps between the slider 131 and the base 132 and the Y-axis air bearing guide 12 and the base 1, the gas will fill these gaps under pressure, forming a continuous gas film, i.e., an air cushion. This enables the air bearing block 13 to move on the base 1 with frictionless and high precision.

[0025] In this embodiment, refer to the appendix to the specification. Figures 1-5 Mounting plates 2 can be detachably installed on both sides of the top of the base 1. Each mounting plate 2 has a movable groove 3 machined on its top, and each side of the top of the base 1 has a mounting groove 5 that matches the mounting plate 2. The two mounting plates 2 are respectively located within the two mounting grooves 5. Simultaneously, spring pins 6 are fixedly inserted through the inner wall of the opposite side of each mounting groove 5, and slots 7 that match the spring pins 6 are machined on the opposite side of each mounting plate 2. The spring pins 6 engage with the slots 7. In actual use, multiple spring pins 6 and slots 7 can be used to improve the connection strength between the mounting plate 2 and the base 1. The use of spring pins 6 in the modular air-floating platform design is more cost-effective than hydraulic locking and electromagnetic locking, costing only about 1 / 100th of their price; maintenance and replacement are extremely convenient, requiring only about one minute; and it also offers a lighter weight.

[0026] To facilitate quick and easy assembly and disassembly of the X-axis air-bearing guide 11, the X-axis air-bearing guide 11 is inserted into the moving groove 3 and connected via an insertion mechanism 4. Specifically, the insertion mechanism 4 includes a lead screw 41 rotatably disposed within the moving groove 3. Two nut blocks 42 are threadedly connected to the lead screw 41. The threads of the two nut blocks 42 and the lead screw 41 have opposite directions, causing the two nut blocks 42 to move in opposite directions. Both X-axis air-bearing guides 11 have slots 43 machined on their surfaces to fit the nut blocks 42. The nut blocks 42 are inserted into the slots 43. Furthermore, an elastic pad can be provided at the insertion point of the nut blocks 42 and the slots 43 for damping and buffering.

[0027] Next, a fixed groove 8 connected to the moving groove 3 is machined on the bottom of both mounting plates 2. A servo motor 44 is detachably connected in the fixed groove 8. The connection between the fixed groove 8 and the moving groove 3 ensures good heat dissipation for the servo motor 44 during use. Specifically, a fixed plate 45 is fixedly installed on the bottom of both servo motors 44. The fixed plate 45 is detachably installed in the fixed groove 8 by bolts. Loosening the bolts makes it easy for the staff to disassemble the servo motor 44 for replacement. The output shaft of the servo motor 44 is connected to the lead screw 41 for transmission.

[0028] In actual use, a gear set is used to connect the servo motor 44 and the lead screw 41, so that the servo motor 44 drives the lead screw 41 to rotate. The two nut blocks 42 on the lead screw 41 move synchronously, so that the two nut blocks 42 are respectively inserted into the two slots 43, thereby firmly fixing the X-axis air bearing guide rail 11 to the mounting plate 2. When the X-axis air bearing guide rail 11 needs to be replaced, the servo motor 44 drives the lead screw 41 to rotate in the opposite direction, so that the X-axis air bearing guide rail 11 can be loosened for disassembly and replacement.

[0029] Furthermore, limiting grooves 133 are machined on both the front and rear sides of the slider 131, and limiting blocks 134 are fixedly provided on both the front and rear sides of the base 132. The limiting blocks 134 are slidably disposed in the limiting grooves 133 and are detachably connected to the slider 131 by bolts. By loosening the bolts between the limiting blocks 134 and the slider 131, the operator can quickly separate the base 132 and the slider 131 for replacement.

[0030] The various embodiments in this specification are described in a related manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
