Description

Technical Field

[0001] This utility model relates to the field of precision machinery technology, and in particular to a bidirectional detection pin mechanism based on air flotation guidance. Background Technology

[0002] In the field of modern industrial inspection, bidirectional inspection pin mechanisms are widely used in machining, automated assembly, and other scenarios as key components for achieving precise positioning and dimensional inspection. The stability and adaptability of bidirectional inspection pin mechanisms directly affect inspection accuracy and production efficiency. With the development of precision machinery technology, the performance requirements for precision motion guide mechanisms have increased. Against this background, bidirectional inspection pin mechanisms based on air-bearing guidance have emerged to meet the needs of high-precision inspection fields.

[0003] The limiting structure of existing bidirectional detection pin mechanisms is mostly fixed directly with bolts, which makes it difficult to provide a stable limiting effect during the operation of the bidirectional detection pin. This can easily lead to positional wobbling and accelerated wear. Moreover, it is impossible to adjust its size according to different specifications of bidirectional detection pin mechanisms, resulting in a limited range of applicability. Utility Model Content

[0006] Through the above technical solution: the first E-shaped plate and the second E-shaped plate installed on the inner wall of the workbench are limited by the workbench. The first E-shaped plate and the second E-shaped plate can effectively limit and guide the bidirectional detection pin, preventing the bidirectional detection pin from deviating during movement. The first limit post and the second limit post can effectively limit the pin through the slot to prevent shaking during movement.

[0007] Preferably, the drive assembly includes an electric push rod, the outer wall of which is fixedly connected to the lower surface of the worktable, the output end of which is fixedly connected to a U-shaped seat, the inner wall of which is fixedly connected to a third limiting post, the outer wall of which is rotatably connected to the inner wall of the first transmission plate, and the outer wall of which is rotatably connected to the inner wall of the second transmission plate.

[0008] Preferably, an air pump is fixedly connected to the upper surface of the base, and one end of an air outlet pipe is fixedly connected to the output end of the air pump, while the other end of the air outlet pipe is fixedly connected to the outer wall of the nozzle.

[0010] Preferably, a filter plate is slidably connected to the inner wall of the filter tank, and a second sliding column is slidably connected inside the filter plate.

[0011] Preferably, one end of the second spring is fixedly connected to the outer wall of the second slide column, and the other end of the second spring is fixedly connected to the inner wall of the filter plate.

[0012] Preferably, the filter tank is slidably connected to a first sliding column, the outer wall of the first sliding column abuts against the outer wall of a second sliding column, a limit pin is fixedly connected to the outer wall of the first sliding column, one end of a first spring is fixedly connected to the outer wall of the limit pin, and the other end of the first spring is fixedly connected to the inner wall of the filter tank.

[0013] Preferably, a third sliding column is slidably connected inside the filter tank, an L-shaped plate is fixedly connected to the outer wall of the third sliding column, the lower surface of the L-shaped plate is slidably connected to the inner wall of the filter tank, a fixing plate is slidably connected to the outer wall of the L-shaped plate, the outer wall of the fixing plate is fixedly connected to the outer wall of the filter plate, one end of a third spring is fixedly connected to the outer wall of the L-shaped plate, and the other end of the third spring is fixedly connected to the inner wall of the filter tank.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, when the second limiting post moves, it drives the second E-shaped plate to move, causing the second E-shaped plate to slide on the inner wall of the worktable during the movement, thereby achieving the effect of limiting the bidirectional detection pin mechanism. This is beneficial to the stability of the bidirectional detection pin mechanism during operation, reducing shaking, reducing wear, and extending service life.

[0016] 2. In this utility model, the second sliding column slides inside the filter plate during the movement, thereby causing the second sliding column to drive the second spring to move. When the second sliding column slides out of the filter tank, the filter plate can be replaced. This helps to reduce the impact of the replacement process on the filter tank and improve the replacement efficiency of the filter plate.

[0017] 3. In this utility model, the reset of the third spring drives the L-shaped plate to move, causing the L-shaped plate to slide on the inner wall of the filter tank during movement. At the same time, the L-shaped plate will slide on the outer wall of the fixed plate during movement, thereby achieving the effect of replacing the filter plate. This is beneficial for quick replacement when the filter plate needs to be replaced, without disassembling the filter tank, thus shortening the replacement time. Attached Figure Description

[0027] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of this utility model. Example

[0028] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a bidirectional detection pin mechanism based on air flotation guidance, comprising a base 1, a support column 2 fixedly connected to the upper surface of the base 1, a worktable 3 fixedly connected to the upper surface of the support column 2, a slot 4 formed on the upper surface of the worktable 3, a first E-shaped plate 5 slidably connected to the inner wall of the worktable 3, a second E-shaped plate 6 slidably connected to the inner wall of the worktable 3, a nozzle 7 fixedly connected to the inner wall of the first E-shaped plate 5, a jet nozzle 8 fixedly connected to the outer wall of the nozzle 7, a first limiting post 9 fixedly connected to the lower surface of the first E-shaped plate 5, the outer wall of the first limiting post 9 slidably connected to the inner wall of the slot 4, a first transmission plate 10 rotatably connected to the outer wall of the first limiting post 9, a second limiting post 11 fixedly connected to the lower surface of the second E-shaped plate 6, the outer wall of the second limiting post 11 slidably connected to the inner wall of the slot 4, a second transmission plate 12 rotatably connected to the outer wall of the second limiting post 11, and a drive assembly provided on the lower surface of the worktable 3;

[0029] Specifically, the support column 2 provides stable support for the worktable 3, which provides sliding space for the first E-shaped plate 5 and the second E-shaped plate 6. The slot 4 on the upper surface of the worktable 3 limits the first limiting column 9 and the second limiting column 11 to ensure that they do not deviate during movement. The first limiting column 9 and the second limiting column 11 convert the rotational motion of the first transmission plate 10 and the second transmission plate 12 into the horizontal linear movement of the first E-shaped plate 5 and the second E-shaped plate 6. The first E-shaped plate 5 provides stable support for the nozzle 7. The nozzle 7 has a hollow internal structure and an air jet head 8 on its outer wall. Gas enters the nozzle 7 and is ejected through the air jet head 8. The first transmission plate 10 connects and transmits the third limiting column 15 and the first limiting column 9. The second transmission plate 12 connects and transmits the third limiting column 15 and the second limiting column 11.

[0030] Reference Figure 2 and Figure 3 The drive assembly includes an electric push rod 13. The outer wall of the electric push rod 13 is fixedly connected to the lower surface of the worktable 3. The output end of the electric push rod 13 is fixedly connected to a U-shaped seat 14. The inner wall of the U-shaped seat 14 is fixedly connected to a third limiting post 15. The outer wall of the third limiting post 15 is rotatably connected to the inner wall of the first transmission plate 10 and the outer wall of the third limiting post 15 is rotatably connected to the inner wall of the second transmission plate 12.

[0031] Specifically, the worktable 3 can fix the electric push rod 13, ensuring the stability of the electric push rod 13 during operation and preventing the electric push rod 13 from shaking during operation. The movement of the output end of the electric push rod 13 drives the U-shaped seat 14 to move. The U-shaped seat 14 is used to connect and transmit power between the electric push rod 13 and the third limiting post 15. The third limiting post 15 can limit the first transmission plate 10 and the second transmission plate 12, ensuring that the first transmission plate 10 and the second transmission plate 12 always move along the circumference during rotation.

[0032] Reference Figure 1 , Figure 4 and Figure 5An air pump 16 is fixedly connected to the upper surface of the base 1. One end of an air outlet pipe 17 is fixedly connected to the output end of the air pump 16, and the other end of the air outlet pipe 17 is fixedly connected to the outer wall of the nozzle 7. One end of an air inlet pipe 18 is fixedly connected to the input end of the air pump 16, and the other end of the air inlet pipe 18 is fixedly connected to a filter tank 19. The lower surface of the filter tank 19 is fixedly connected to the upper surface of the base 1. A filter plate 20 is slidably connected to the inner wall of the filter tank 19, and a second sliding column 24 is slidably connected inside the filter plate 20. One end of a second spring 25 is fixedly connected to the outer wall of the second sliding column 24, and the other end of the second spring 25 is fixedly connected to the inner wall of the filter plate 20. A first sliding column 21 is slidably connected inside the filter tank 19, and the outer wall of the first sliding column 21 abuts against the outer wall of the second sliding column 24. A limit pin 22 is fixedly connected to the outer wall of the first sliding column 21, and one end of a first spring 23 is fixedly connected to the outer wall of the limit pin 22, and the other end of the first spring 23 is fixedly connected to the inner wall of the filter tank 19.

[0033] Specifically, the base 1 can fix the air pump 16, ensuring its stability during operation. The air pump 16 is used to draw gas from inside the filter tank 19 into the air pump 16 through the air inlet pipe 18. The air outlet pipe 17 is used to draw gas from inside the air inlet pipe 18 into the nozzle 7 through the air pump 16. The filter tank 19 provides space for the filter plate 20 to be installed. The filter plate 20 is used to filter the gas entering the air pump 16, preventing impurities from clogging the air pump 16. The filter tank 19 can limit the movement of the first sliding column 21, ensuring that the first sliding column 21 always moves in a horizontal straight line during movement. One end of the first spring 23 is fixedly connected to the outer wall of the limiting pin 22, and the other end of the first spring 23 is fixedly connected to the inner wall of the filter tank 19, which limits the elastic range of the first spring 23 and ensures that the first spring 23 maintains a certain pushing force. The second sliding column 24 and the filter plate 20 can limit the movement of the second spring 25, ensuring that the second spring 25 will not become unstable during movement. Example

[0034] Reference Figure 6 and Figure 7 The filter tank 19 is slidably connected to a third sliding column 27. An L-shaped plate 28 is fixedly connected to the outer wall of the third sliding column 27. The lower surface of the L-shaped plate 28 is slidably connected to the inner wall of the filter tank 19. A fixing plate 26 is slidably connected to the outer wall of the L-shaped plate 28. The outer wall of the fixing plate 26 is fixedly connected to the outer wall of the filter plate 20. One end of a third spring 29 is fixedly connected to the outer wall of the L-shaped plate 28. The other end of the third spring 29 is fixedly connected to the inner wall of the filter tank 19.

[0035] Specifically, when the filter plate 20 needs to be replaced, the third sliding column 27 is pushed inward, causing it to slide inside the filter tank 19. This movement causes the L-shaped plate 28 to move, sliding against the inner wall of the filter tank 19 and simultaneously against the outer wall of the fixing plate 26. During this process, the L-shaped plate 28 moves, causing the third spring 29 to move. When the L-shaped plate 28 moves away from the fixing plate 26, the filter plate 20 can be replaced. After replacement, the third sliding column 27 is released, and the third spring 29 resets, causing the L-shaped plate 28 to move again, sliding against the inner wall of the filter tank 19 and simultaneously against the outer wall of the fixing plate 26. This achieves the effect of replacing the filter plate 20, allowing for quick replacement without disassembling the filter tank 19 and shortening the replacement time.

[0036] Working principle: When the bidirectional detection pin mechanism needs to be limited, the electric push rod 13 is activated. The movement of the output end of the electric push rod 13 drives the U-shaped seat 14 to move. During the movement of the U-shaped seat 14, the third limiting post 15 moves. During this process, the movement of the third limiting post 15 drives the first transmission plate 10 to rotate. During the rotation of the first transmission plate 10, the first limiting post 9 moves, causing the first limiting post 9 to slide against the inner wall of the slot 4. This movement of the first limiting post 9 then drives the first E-shaped plate 5 to move, causing the first E-shaped plate 5 to move during its movement. Sliding on the inner wall of the worktable 3, the third limiting post 15 moves, causing the second transmission plate 12 to rotate. During the rotation of the second transmission plate 12, the second limiting post 11 moves, causing the second limiting post 11 to slide on the inner wall of the slot 4. This movement of the second limiting post 11 then causes the second E-shaped plate 6 to move, also causing it to slide on the inner wall of the worktable 3. This achieves the effect of limiting the bidirectional detection pin mechanism, which helps to stabilize the position of the bidirectional detection pin mechanism during operation, reduces shaking, reduces wear, and extends service life.

[0037] When the filter plate 20 needs to be replaced, the first sliding column 21 is pushed inward, causing it to slide inside the filter tank 19 during movement. This causes the first sliding column 21 to move the limiting pin 22, which in turn slides against the inner wall of the filter tank 19. Consequently, the limiting pin 22 moves the first spring 23. During this process, the movement of the first sliding column 21 causes the second sliding column 24 to move, sliding inside the filter plate 20. This in turn causes the second sliding column 24 to move the second spring 25. When the second sliding column 24 slides out of the filter tank 19, the filter plate 20 can be replaced. This reduces the impact of the replacement process on the filter tank 19 and improves the replacement efficiency of the filter plate 20.

[0038] When the nozzle 7 needs to spray air, the air pump 16 is activated to force air through the filter pool 19 into the air pump 16. During this process, the gas enters the exhaust pipe 17 through the air pump 16, and then enters the nozzle 7 through the exhaust pipe 17, and then enters the jet head 8 through the nozzle 7, thereby achieving the jet spraying effect. This helps to ensure the smoothness of the jet spraying process and the continuity of the jet spraying effect.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
