Description

Technical Field

[0001] The utility model belongs to the field of air floating guide rail protection, and specifically relates to a protection device for an air floating guide rail. Background Technique

[0002] An air floating guide rail is a guide rail system that uses gas power to achieve suspended operation. It is based on the gas static and dynamic pressure effects, and generates a suspension force through the pressure of the gas, enabling the object on the guide rail to move freely in the air film, thereby achieving smooth movement without friction and vibration.

[0003] An air floating guide rail generally consists of a guide rail and a slider. By injecting gas into the slider and spraying the gas through the air outlet openings on the surface of the slider between the guide rail and the slider, an air film is formed to lift the slider to form suspension. At this time, the slider can move smoothly along the guide rail, and it is difficult for the slider to generate friction with the guide rail during the sliding process.

[0004] However, when the air floating guide rail is in use, the gas flow rate injected into the slider gradually increases, so it takes a certain amount of time to form a stable air film between the slider and the guide rail. If the motor is started to drive the slider to move before the air film is stable or the slider itself is offset due to the air flow, it is easy to cause wear between the slider and the guide rail, resulting in wear of the air floating guide rail and reducing the accuracy of the air floating guide rail.

[0005] Therefore, the utility model provides a protection device for an air floating guide rail. Summary of the Utility Model

Specific embodiments

[0023] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Such as Figures 1 to 5As shown in the figure, a protection device for an air-floating guide rail according to an embodiment of the present utility model includes a long plate 1; an air inlet groove 12 is formed at the top of the long plate 1; a plurality of air guide grooves 13 are formed inside the long plate 1; the plurality of air guide grooves 13 communicate with the air inlet groove 12; a fixed cylinder 14 is fixedly connected to the top of the long plate 1; the fixed cylinder 14 communicates with the plurality of air guide grooves 13; a pair of guide rods 15 are fixedly connected to the top of the long plate 1; a slide plate 16 is slidably connected to the middle of the guide rod 15; the slide plate 16 is also slidably connected to the inside of the fixed cylinder 14; an air vent 17 is formed in the middle of the slide plate 16; an exhaust port 18 is formed in the middle of the fixed cylinder 14; during operation, the long plate 1 is inserted between the guide rail and the slider, so that the air inlet groove 12 communicates with the air outlet of the slider, and then the air supply device is started to supply air into the slider. Then, the gas will be sprayed into the inside of the air inlet groove 12 through the air outlet of the slider and flow out through the air vent 17. During this process, the air flow will impact the bottom of the slide plate 16 and push the slide plate 16 upward. As the gas flow rate at the air outlet of the slider gradually increases, the gas flow rate through the air vent 17 will also gradually increase. At this time, the slide plate 16 will be gradually pushed upward. When the gas flow rate reaches a certain level, the slide plate 16 will slide above the exhaust port 18, and at this time, part of the air flow will flow out through the exhaust port 18. At this time, it means that the gas flow rate sprayed out of the air outlet of the slider reaches a certain level. Then, the long plate 1 can be pulled out from between the guide rail and the slider. At this time, the air flow sprayed out by the slider is sufficient to form a stable air film between the slider and the guide rail. Then, the motor is started to drive the slider to run. Through the above structure, the wear between the guide rail and the slider caused by the unstable formation of the air film can be reduced, thereby reducing the occurrence of the reduction of the accuracy of the air-floating guide rail.

[0025] As Figures 1 to 5 shown, a rotating rod 2 is rotatably connected to the top of the slide plate 16; a regulating baffle 21 is fixedly connected to the middle of the rotating rod 2; both the regulating baffle 21 and the slide plate 16 are semicircular; the regulating baffle 21 is arranged to fit the top of the slide plate 16; during operation, the rotating rod 2 is rotated to drive the regulating baffle 21 to rotate, so that the regulating baffle 21 blocks part of the top of the air vent 17, thereby expanding or reducing the channel of the air vent 17. When the air flow channel is expanded, a greater gas flow rate is required to push the slide plate 16 to the specified position. When the air flow channel is reduced, only a smaller gas flow rate is required to push the slide plate 16 to the specified position. Through the above structure, the air flow intensity sprayed out by the slider can be adjusted according to the weight of the slider and the object carried by the slider, and the device can be adapted to different air flow intensity requirements by adjusting the regulating baffle 21.

[0026] As Figures 1 to 5As shown, a whistle tube 3 is fixedly connected to the side wall of the fixed cylinder 14; the whistle tube 3 is communicated with the exhaust port 18; a whistle piece 31 is fixedly connected inside the whistle tube 3; during operation, when the air flow jets out through the exhaust port 18, the air flow will pass through the whistle piece 31 and generate a whistle sound, thereby reminding the staff and enabling the staff to easily distinguish whether the air flow intensity meets the standard.

[0027] As Figures 1 to 4 shown, a plurality of films 4 are fixedly connected to the top of the long board 1; the plurality of films 4 are arranged around the air inlet groove 12; during operation, when the long board 1 is placed between the guide rail and the slider, the arrangement of the plurality of films 4 can reduce the occurrence of gas overflowing from other places, thereby being able to detect the air flow intensity more accurately and improving the protection effect on the air floating guide rail.

[0028] As Figures 1 to 3 shown, the long board 1 is made of a rubbery material; a plurality of reinforcing rods 5 are fixedly connected inside the long board 1; during operation, when the rubbery long board 1 is placed between the guide rail and the slider, it can reduce the wear on the air floating guide rail, and the arrangement of the reinforcing rods 5 can prevent the long board 1 from being easily bent during installation, enabling the long board 1 to be more easily inserted between the guide rail and the slider.

[0029] As Figures 1 to 5 shown, a circular plate 6 is fixedly connected to the top end of the rotating rod 2; a scale line 61 is opened on the top of the circular plate 6; a comparison line 62 is opened on the side wall of the fixed cylinder 14; through the above structure, when adjusting the size of the air flow channel of the air vent 17, the rotation angle of the adjusting baffle 21 can be adjusted more accurately, thereby improving the accuracy of the air flow intensity detection and thus improving the protection effect on the air floating guide rail.

[0030] As Figure 3 shown, a plurality of grooves 7 are opened at the bottom of the long board 1; the plurality of grooves 7 are evenly distributed at the bottom of the long board 1; through the above structure, when the long board 1 is pulled out from between the guide rail and the slider, the adhesion between the long board 1 and the guide rail can be reduced, thereby reducing the obstruction to pulling out the long board 1.

[0031] During operation, insert the long board 1 between the guide rail and the slider, so that the air inlet groove 12 communicates with the air outlet of the slider. Then start the air supply device to supply air into the slider. Then the gas will be sprayed into the interior of the air inlet groove 12 through the air outlet of the slider and flow out through the air vent 17. During this process, the air flow will impact the bottom of the skateboard 16 and push the skateboard 16 upward. As the gas flow rate at the air outlet of the slider gradually increases, the gas flow rate through the air vent 17 will also gradually increase. At this time, the skateboard 16 will be gradually pushed upward. When the gas flow rate reaches a certain level, the skateboard 16 will slide above the exhaust port 18. At this time, part of the air flow will flow out through the exhaust port 18. At this time, it means that the gas flow rate ejected from the air outlet of the slider reaches a certain level. Then the long board 1 can be pulled out from between the guide rail and the slider. At this time, the air flow ejected from the slider is sufficient to form a stable air film between the slider and the guide rail. Then start the motor to drive the slider to run. Rotate the rotating rod 2 to drive the adjusting baffle 21 to rotate, so that the adjusting baffle 21 blocks the top of part of the air vent 17, thereby expanding or reducing the channel of the air vent 17. When the air flow channel is expanded, a greater gas flow rate is required to push the skateboard 16 to the designated position. When the air flow channel is reduced, only a smaller gas flow rate is required to push the skateboard 16 to the designated position. When the air flow is ejected through the exhaust port 18, the air flow will pass through the reed 31 and produce a whistling sound. When the long board 1 is placed between the guide rail and the slider, the setting of multiple films 4 can reduce the occurrence of gas overflowing from other places. When the gelatinous long board 1 is placed between the guide rail and the slider, it can reduce the wear of the air-floating guide rail. The setting of the reinforcement rod 5 can prevent the long board 1 from being easily bent during installation. When adjusting the air flow channel size of the air vent 17, the rotation angle of the adjusting baffle 21 can be adjusted more accurately.
