Technical Field

[0001] The present invention belongs to the field of aerospace technology, and in particular relates to a floating guide mechanism. Background Art

[0002] In aviation engineering projects, various displacement units must perform various mechanical actions and displacement conversions. These actions require the assistance of guide mechanisms to ensure that the units move along the guide rails. The primary function of guide mechanisms is to ensure that the units move in a fixed direction. Guide wheels are the core components of these mechanisms, providing guidance and support for the displacement of the units, ensuring the correct direction of movement and reducing friction.

[0003] Traditional guide wheels often work in harsh environments with low temperatures and high dust content. As the working time and number of working times increase, a lot of dust will accumulate on the surface of the traditional guide wheels, which will greatly reduce the guiding effect of the guide wheels. In addition, since dust can easily enter the guide wheels, it will cause the guide wheels to get stuck.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a floating guide mechanism. Summary of the Invention

[0029] This embodiment provides a floating guide mechanism, such as Figures 1 to 7 As shown, it includes a sliding shoe 1 and a guide column 2, and the sliding shoe 1 is slidingly connected to the guide column 2. The sliding shoe 1 includes: a support body 3, which is arranged on two adjacent side surfaces facing the guide column 2; a support surface 4, which is arranged on the side of the support body 3 facing the guide column 2 and is connected to the support body 3; a dust guide groove 5, which is arranged between adjacent support surfaces 4 and extends along the sliding direction of the support body 3 relative to the guide column 2; a dust removal claw 6, which is symmetrically arranged on the upper and lower end surfaces of the support body 3 and is connected to the support body 3; a dust containing groove 7, which is arranged between the support body 3 and the dust removal claw 6, and is connected to both the support body 3 and the dust removal claw 6.

[0030] Exemplarily, the sliding shoe 1 includes a support body 3, a support surface 4, a dust guide groove 5, a dust removal claw 6 and a dust containing groove 7, so that when the sliding shoe 1 slides relative to the guide column 2, the dust removal claw 6 arranged on the end face of the support body 3 scrapes the dust to the upper and lower ends of the guide column 2, so that the dust on the floating guide mechanism no longer accumulates and gradually falls off, thereby playing a role in dust removal. In addition, the dust guide groove 5 and the dust containing groove 7 arranged on the sliding shoe 1 further prevent dust from accumulating on the sliding path of the sliding shoe 1, increase the dustproof effect, thereby ensuring the guiding function of the floating guide mechanism and effectively avoiding the floating guide mechanism from getting stuck.

[0031] In one possible embodiment, Figure 1 、 Figure 2 and Figure 3As shown, the dust removal claw 6 includes: a first bending portion 8, which is connected to the support body 3 and bent toward the guide column 2; a second bending portion 9, which is connected to the first bending portion 8 and bent in a direction away from the guide column 2; a sliding surface 10, which is arranged at the connection between the first bending portion 8 and the second bending portion 9, and is higher than the support surface 4 in the direction extending to the guide column 2.

[0032] For example, the dust on the upper end of the dust removal claw 6 will move back and forth with the dust removal claw 6. During the reciprocating movement of the sliding shoe 1, since the sliding surface 10 is in close contact with the side of the guide column 2, the second bent portion 9 will scrape the dust attached to the guide column 2 at the upper end of the dust removal claw 6 to the upper end of the guide column 2. When too much dust accumulates, the dust will fall off automatically, thereby achieving the dust-proof effect of the floating guide mechanism and ensuring the guiding function of the floating guide mechanism.

[0033] For example, dust at the lower end of the dust removal claw 6 is pulled back and forth by the reciprocating motion of the dust removal claw 6, causing the sliding shoe 1 to reciprocate. Because the sliding surface 10 is in close contact with the side of the guide post 2, the second bent portion 9 scrapes dust adhering to the guide post 2 at the lower end of the dust removal claw 6 toward the lower end of the guide post 2. When excessive dust accumulates, the dust automatically falls off. On the surface of the guide post 2 between the dust removal claws 6 at the upper and lower ends of the support body 3 on the same side, the dust removal claw 6 repeatedly scrapes dust toward the upper and lower ends of the guide post 2, preventing the dust from affecting the floating guide mechanism. Even if there is a lot of dust, it will automatically fall off, thereby achieving the dust-proof effect of the floating guide mechanism and ensuring its guiding function.

[0034] For example, Figure 4 As shown, when the guide screw 11 rotates right, the guide body 15 has a left-hand tendency and generates a torsion. Figure 4 The visible dust removal claw 6 on the left side of the center is pressed against the guide post 2, while the invisible dust removal claw 6 on the left side, which is blocked by the guide post 2, is relaxed. On the right side, the visible dust removal claw 6 is relaxed, while the invisible dust removal claw 6 blocked by the guide post 2 is pressed against the guide post 2. The distance between the support surface 4 of the sliding shoe 1 and the guide post 2 at the point where the dust removal claw 6 is pressed is compressed from 0.1mm in the pressed state to 0.05mm or to fit (0.3mm in the relaxed state, with a pre-compression of 0.2mm after installation). The distance between the support surface 4 of the sliding shoe 1 and the guide post 2 at the relaxed point is relaxed from 0.1mm in the pressed state to 0.15mm or 0.2mm. With this arrangement, the guide body 15 is in a floating state relative to the guide column 2, that is, it becomes a floating guide mechanism. Through the arrangement of the sliding shoe 1, the floating guide mechanism can offset the torque generated by the guide body 15 during the rotation process, and because the support surface 4 on the compressed side is also compressed or fitted with the guide column 2, it plays a role in preventing the guide body 15 from rotating, and ultimately effectively ensures the guiding effect of the floating guide mechanism.

[0035] For example, Figure 4 As shown, when the guide screw 11 rotates left, the guide body 15 has a right-handed tendency and generates a torsional force. Figure 4 The dust removal claw 6 visible on the left side of the center is relaxed, while the invisible dust removal claw 6 on the left side, which is blocked by the guide post 2, is pressed against the guide post 2. The distance between the support surface 4 of the sliding shoe 1 and the guide post 2 at the relaxed dust removal claw 6 is relaxed from 0.1mm in the compressed state to 0.15mm or 0.2mm. The distance between the support surface 4 of the sliding shoe 1 and the guide post 2 at the compressed dust removal claw 6 is compressed from 0.1mm in the compressed state to 0.05mm or close contact (0.3mm in the relaxed state, pre-loaded 0.2mm after installation). With this arrangement, the guide body 15 floats relative to the guide post 2, forming a floating guide mechanism. The arrangement of the sliding shoe 1 allows the floating guide mechanism to offset the torsional force generated by the guide body 15 during rotation. Furthermore, since the support surface 4 on the compressed side is also compressed or close contact with the guide post 2, it prevents the guide body 15 from rotating, ultimately effectively ensuring the guiding function of the floating guide mechanism.

[0036] In one possible embodiment, Figure 1 、 Figure 2 and Figure 3 As shown, the planes where adjacent supporting surfaces 4 are located are perpendicular to each other.

[0037] For example, the planes of adjacent support surfaces 4 are perpendicular to each other, meaning the shoe 1 forms a mirrored 90° structure. The dust removal claws 6 contact and compress two adjacent side surfaces of the guide post 2, respectively. Adjustment of the connecting holes 20 allows the sliding surfaces 10 of the four dust removal claws 6 of the shoe 1 to be in close contact with the guide post 2. As the shoe 1 reciprocates relative to the guide post 2, the dust removal claws 6 scrape dust from one side of the guide post 2 to the other, effectively preventing dust. The dust collection grooves 7 between the dust removal claws 6 and the support body 3 also serve to contain dust. During reciprocating motion, a torque is applied to the guide body 15. This torque compresses the dust removal claws 6 on one side, forcing the support surface 4 of the shoe 1 on the compressed side into contact with the guide post 2, while the sliding surfaces 10 of the dust removal claws 6 on the other side of the shoe 1 remain in contact with the guide post 2. This arrangement ensures the dust removal function of the shoe 1 while preventing the guide body 15 from rotating.

[0038] For example, the sliding shoe 1 is provided with a dust collection groove 7 and a dust guide groove 5. This configuration optimizes the structure of the floating guide mechanism, increasing the safety margin rather than actively containing dust. When the floating guide mechanism operates in a low-temperature, harsh environment, the amount of dust is unknown, and whether there will be wind to accelerate dust flow is also unknown. Therefore, it is necessary to maximize the space for temporary dust storage. When the operating environment is windy, dust will be blown along the support surface 4 on one side to the support surface 4 on the other side and adhere to the surface of the guide column 2. The dust guide groove 5 at the 90° mirrored structural connection of the sliding shoe 1 effectively solves this problem. Most dust is blown into the dust guide groove 5, and a small amount of dust adheres to the support surface 4, without affecting the normal guiding operation of the floating guide mechanism. Furthermore, during the floating guide mechanism's up and down reciprocating motion, the dust collection claw 6 and the dust collection groove 7 on the support body 3 increase the dust storage space, further enhancing the dust-proofing effect of the floating guide mechanism.

[0039] In one possible embodiment, Figure 4 、 Figure 5 and Figure 6 As shown, the guide screw 11 includes a threaded portion 12 and a driving portion 13, and the threaded portion 12 is connected to the driving portion 13; the driving fitting portion 14 is sleeved on the outside of the driving portion 13 and is surrounded by the guide column 2 to form a rectangular frame; the guide body 15 is arranged above the driving fitting portion 14, and the guide body 15 includes a threaded fitting portion 21, and the threaded fitting portion 21 is adapted to the threaded portion 12, so that the guide body 15 and the guide screw 11 are threadedly connected through the threaded fitting portion 21 and the threaded portion 12; the guide connection assembly is arranged between the guide body 15 and the guide column 2, and is connected to both the guide body 15 and the guide column 2.

[0040] For example, the guide screw 11 provides the reciprocating motion power source for the sliding movement of the guide body 15 relative to the guide post 2. Assembly should be based on the actual structure of the guide body 15. The four guide claws 16 extending from the guide body 15 should be retained, and the specific structure of the guide body 15 can be determined based on actual conditions.

[0041] Exemplarily, the driving part 13 includes a flat keyway of the feed motor, and the driving part 13 is key-connected to the feed motor. The feed motor provides driving force for the driving part, thereby driving the guide screw 11 to rotate. The guide screw 11 drives the guide body 15, so that the guide body 15 reciprocates up and down relative to the guide column 2, thereby realizing the guiding function of the floating guide mechanism.

[0042] Exemplarily, the driving part 13 includes a connecting key, the driven gear is connected to the driving part 13, and the driving gear is connected to the motor shaft to realize the acceleration or deceleration of the driving part 13, thereby providing driving force for the guide screw 11, driving the guide screw 11 to rotate, and the guide screw 11 drives the guide body 15, so that the guide body 15 reciprocates up and down relative to the guide column 2, thereby realizing the guiding effect of the floating guide mechanism.

[0043] In one possible embodiment, Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, the guide connection assembly includes: a guide claw 16, which is arranged between the guide body 15 and the guide column 2 and connected to the guide body 15; a sliding pad 17, which is arranged between the guide claw 16 and the guide column 2 and connected to the guide claw 16.

[0044] Exemplarily, the guide claw 16 is welded to the guide body 15, the sliding pad 17 is connected to the guide claw 16 by a screw, and a gasket can be added between the sliding pad 17 and the guide claw 16 to adjust the distance between the sliding pad 17 and the guide claw 16 along the screw direction to offset the torque generated by the guide body 15 during rotation.

[0045] In one possible embodiment, Figure 4 、 Figure 5 and Figure 6 As shown, the number of guide claws 16 is four, the number of sliding pads 17 is four, and the number of sliding shoes 1 is four.

[0046] For example, the guide body 15 has four guide claws 16, corresponding to four sliding pads 17 and four sliding shoes 1. This means the sliding body is slidably connected to the guide post 2 via four sets of guide claws 16, sliding pads 17, and sliding shoes 1. The specific structural shape of the guide body 15 can be assembled with the sliding pads 17, and the guide body 15 is provided with M3 threaded holes. The remaining parts of the guide body 15 are schematic and can be designed based on actual conditions, and are not specifically limited here.

[0047] In one possible embodiment, Figure 3 、 Figure 6 and Figure 7 As shown, the sliding pad 17 includes: an inserting portion 18, which is provided at the end of the sliding pad 17 and connected to the sliding shoe 1.

[0048] For example, the plug-in portion 18 of the sliding pad 17 is L-shaped and has a clearance fit with the sliding shoe 1, which facilitates assembly. After assembly, the sliding pad 17 and the sliding shoe 1 are tightly assembled and will not fall off.

[0049] In one possible embodiment, Figure 3 、 Figure 6 and Figure 7 As shown, the support body 3 further includes: a slot 19 , which is provided on the side of the support body 3 facing away from the support surface 4 and is adapted to the plug-in portion 18 to connect the sliding shoe 1 with the sliding pad 17 .

[0050] Exemplarily, one end of the sliding pad 17 connected to the sliding shoe 1 is designed to be L-shaped, so that the sliding pad 17 and the sliding shoe 1 are clearance-fitted. This clearance-fit makes use of the good plasticity of polytetrafluoroethylene. The L-shaped plug-in portion 18 and the side parallel to the main body of the sliding pad 17 can be first inserted into the slot 19 of the sliding shoe 1, and then the two supporting surfaces 4 of the sliding shoe 1 are fitted together, so that the side of the sliding pad 17 perpendicular to the main body of the sliding pad 17 can be smoothly inserted into the other slot 19 of the sliding shoe 1. In this way, the plug-in portion 18 and the slot 19 are assembled, that is, the sliding pad 17 and the sliding shoe 1 are assembled. At this time, the planes where the two adjacent supporting surfaces 4 of the sliding shoe 1 are located are perpendicular to each other, that is, there is a 90° right angle between the two supporting surfaces 4.

[0051] For example, the sliding shoe 1 made of polytetrafluoroethylene is loosely connected to the sliding pad 17 made of titanium alloy through a clearance fit.

[0052] In one possible embodiment, Figure 7 As shown, the sliding pad 17 includes: a connecting hole 20, which is provided through the middle of the sliding pad 17, and the connecting hole 20 is a long through hole.

[0053] Exemplarily, the connecting hole 20 is a long through hole. When the sliding pad 17 is connected to the guide body 15 by screws, the sliding pad 17 can adjust its position left and right, and the movement amount is 0.3 mm. This setting allows the guide body 15 and the guide column 2 to be adjusted in the horizontal direction, so that the floating guide body 15 is in a floating state.

[0054] For example, adjusting the screw tightening position through the connection hole 20 of the sliding pad 17 can achieve horizontal position adjustment. The screw position can also be adjusted in the opposite direction by installing a shim between the sliding pad 17 and the screw. By adjusting the position of the sliding pad 17 in these two directions, the position of the sliding shoe 1 in both directions can be adjusted to achieve the required preload position of the guide claw 16.

[0055] In a possible embodiment, the material of the sliding shoe 1 is polytetrafluoroethylene.

[0056] For example, the material of the sliding shoe 1 is polytetrafluoroethylene, which has self-lubricating properties and can be used as a solid lubricating material, so that the dust removal claw 6 and the supporting surface 4 have self-lubricating properties, thereby ensuring the guiding function of the sliding shoe 1 and effectively preventing the floating guide mechanism from getting stuck.

[0057] For example, in this embodiment, the provision of a sliding shoe 1 enables the floating guide mechanism to prevent, contain, and remove dust during the guiding process. The polytetrafluoroethylene material used in the sliding shoe 1 provides self-lubrication in low-temperature environments, further preventing the floating guide mechanism from becoming stuck during the guiding process.

[0058] For example, in this embodiment, the dust removal claw 6 is set to a 90° mirror image structure. When torque is applied, the dust removal claw 6 on one side of the sliding shoe 1 is compressed, and the support surface 4 on the compressed side limits the rotation of the support body 3, thereby preventing the guide body 15 from rotating, thereby ensuring the guiding effect of the floating guide mechanism.

[0059] For example, in this embodiment, the 0.3mm movement of the connecting hole 20 of the sliding pad 17 and the connection form of the gasket between the sliding pad 17 and the guide claw 16 make it possible to adjust the guide body 15 and the guide column 2 in the horizontal direction and the depth direction of the connecting bolt, so that the floating guide body 15 is in a floating state, thereby improving the adaptability of the floating guide body 15 and ensuring the guiding effect of the floating guide mechanism.

[0060] 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 modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in 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 of the claims.
