Description

Technical Field

[0001] This utility model relates to the field of slide rail technology, and more specifically, to an integrated anti-collision slide rail with an air bearing. Background Technology

[0002] Air bearings are non-contact support devices that utilize high-pressure gas to form a lubricating film. They achieve frictionless movement by forming a micron-level air film between the bearing and the moving parts using compressed air. Their core feature is the use of gas dynamics principles, which allows the moving parts to be completely suspended above the air film, thus eliminating friction loss and wear caused by mechanical contact. These bearings have significant advantages such as high motion accuracy (down to the nanometer level), no mechanical wear, smooth operation, and low vibration and noise, and are widely used in slide rails.

[0003] For example, Chinese patent disclosure: A T-shaped high-load air-bearing guide rail, application number: CN202420483119.8, includes an upper load plate structure, a lower load slider structure, and a leveling adjustment device. The upper load plate structure includes an upper load plate with side plates and a bottom plate installed on both sides respectively. The lower load slider structure is located under the bottom plate and moves with the upper load plate structure through two limiting baffles. The leveling adjustment device includes limiting components, mounting plates, fixing plates, and adjustment components, located at both ends of the upper surface of the upper load plate and both ends of the lower surface of the guide rail base. The beneficial effects of this utility model are that the strong magnets set in the bottom plate and the lower load slider structure can provide vertical support rigidity, preventing the upper load plate from shifting laterally, thereby avoiding the side plates from locking and wearing with the guide rail; the leveling adjustment device can ensure the installation level of the bottom of the guide rail base and the top of the upper load plate, thereby ensuring the horizontal state of the equipment installed on the fixing plate, improving the stability and accuracy of the movement.

[0004] However, in the above technical solutions, linear motion guides are key components for achieving high-precision positioning in the fields of precision manufacturing, semiconductor processing and automation equipment. When the slider of a traditional guide accidentally hits the stop, it usually relies on contact buffers or mechanical dampers to decelerate. With long-term use, this deceleration method will inevitably lead to wear and failure of the buffer components due to impact, which increases the cost of the equipment. Utility Model Content

[0005] The main purpose of this utility model is to provide an integrated anti-collision slide rail with an air bearing, which can effectively solve the problem in the background art that linear motion slide rails are key components for achieving high-precision positioning in the fields of precision manufacturing, semiconductor processing and automation equipment. When the slider of a traditional slide rail accidentally hits the stop, it usually relies on a contact buffer or mechanical damper for deceleration. This deceleration method inevitably leads to wear and failure of the buffer element due to impact after long-term use, which increases the cost of the equipment.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an integrated anti-collision slide rail with air bearings, including a base, with blocks fixedly arranged on both sides of the base, and a slider arranged between the two blocks. The side of the block near the slider is provided with several grooves and several damping buffer posts. A connecting post is arranged in the groove, and a first magnetic ring is arranged on the connecting post. The first magnetic ring is provided with several through grooves. Several air bearings are arranged on the slider, and second magnetic rings are arranged on both sides of the slider.

[0007] Preferably, the damping buffer column is fixedly installed on the stop block.

[0008] Preferably, the sides of the first magnetic ring and the second magnetic ring that are close to each other have the same pole.

[0009] Preferably, the slider is slidably connected to the base.

[0010] Preferably, the connecting column includes a connecting column base, which slides in a groove, and a spring is fixedly provided on one side of the connecting column base.

[0011] Preferably, one side of the connecting column base is fixedly connected to the first magnetic ring, and the spring is fixedly installed in the slide groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] When the slider moves to a certain stop, the first and second magnetic rings, which repel each other, generate a non-contact reverse force on the slider, achieving non-contact deceleration and avoiding mechanical contact wear to a certain extent. In the initial stage, the repulsive force slowly increases as the distance decreases, achieving pre-deceleration. When the impact energy is large, the first magnetic ring drives the connecting column base to move, and the spring deforms, allowing the first magnetic ring to move axially continuously during the deceleration of the slider. The displacement of the spring automatically increases, and the nonlinear energy storage characteristics of elastic potential energy achieve gradual absorption of impact energy. As the spring compression increases, its restoring force and magnetic repulsive force are enhanced synergistically, forming an adaptive damping gradient, so that the deceleration process always maintains the optimal buffering effect. Furthermore, as the first magnetic ring moves, the buffering deceleration time is extended, thereby improving the deceleration effect.

[0014] If the impact energy is too large and the magnetic repulsion force cannot completely stop the slider, the first magnetic ring moves to the damping buffer column. One of the damping buffer columns passes through the through groove, thereby using several damping buffer columns to buffer and decelerate the slider, preventing damage to the slider and the stop due to collision, ensuring reliability. It can cope with the flexible deceleration under normal working conditions and withstand sudden and severe impacts. Attached Figure Description

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0020] like Figure 1 and Figure 2 As shown, an integrated anti-collision slide rail with air bearings includes a base 1. Blocks 2 are fixedly arranged on both sides of the base 1, and a slider 8 is arranged between the two blocks 2. Several grooves 3 and several damping buffer columns 4 are arranged on the side of the block 2 near the slider 8. A connecting column 5 is arranged in the groove 3. A first magnetic ring 6 is arranged on the connecting column 5. Several through grooves 7 are arranged on the first magnetic ring 6. Several air bearings 9 are arranged on the slider 8. Second magnetic rings 10 are arranged on both sides of the slider 8.

[0021] like Figure 3 As shown, in another embodiment of the present invention, the connecting column 5 includes a connecting column base 501, the connecting column base 501 slides in the slide groove 3, and a spring 502 is fixedly provided on one side of the connecting column base 501.

[0022] When the first magnetic ring 6 moves due to repulsion, the repulsion force gradually increases as the distance decreases in the initial stage to achieve pre-deceleration. When the impact energy is large, the first magnetic ring 6 drives the connecting column base 501 to move, and the spring 502 deforms, so that the first magnetic ring 6 can continue to move axially during the deceleration of the slider 8. The displacement of the spring 502 automatically increases, and the impact energy is gradually absorbed through the nonlinear energy storage characteristics of elastic potential energy. As the compression of the spring 502 increases, its restoring force and magnetic repulsion force are enhanced in synergy, forming an adaptive damping gradient, so that the deceleration process always maintains the optimal buffering effect, and as the first magnetic ring 6 moves, the buffering deceleration time is extended, thereby improving the deceleration effect.

[0023] The working principle of this integrated anti-collision slide rail with air bearing:

[0024] In use, when the slider 8 moves to a certain stop 2, the first magnetic ring 6 and the second magnetic ring 10, which repel each other, firstly repel the slider 8, thus generating a non-contact reverse force on the slider 8 and achieving non-contact deceleration. Then, in the initial stage, the repulsive force slowly increases as the distance decreases, achieving pre-deceleration. When the impact energy is large, the first magnetic ring 6 drives the connecting column base 501 to move, and the spring 502 deforms, allowing the first magnetic ring 6 to continue axial movement during the deceleration of the slider 8. The displacement of the spring 502 automatically increases, through the nonlinearity of elastic potential energy. The energy storage characteristics enable the gradual absorption of impact energy. As the compression of spring 502 increases, its restoring force and magnetic repulsion force are enhanced in synergy, forming an adaptive damping gradient. At the same time, if the impact energy is too large and the magnetic repulsion force cannot completely stop the slider 8, the first magnetic ring 6 moves to the damping buffer post 4. One damping buffer post 4 passes through the through slot 7, thereby using several damping buffer posts 4 to buffer and decelerate the slider 8, preventing damage to the slider 8 and the stop block 2 due to collision, ensuring reliability. It can cope with the flexible deceleration under normal working conditions and withstand sudden and severe impacts.

[0025] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
