[0004] For the related technology in the above, the inventor believes that the following defects exist: the device drives gear rotation by drive motor, and then gear and rack are matched and drive sliding plate to move, in actual use, the bottom surface of support bearing abuts against the upper surface of guide rail, so that a certain space is left between the bottom surface of sliding plate and the upper surface of guide rail, when workshop environment is relatively chaotic, part of sundries is easy to stay on the upper surface of guide rail, at this time, the height of support bearing is easy to change irregularly when support bearing moves to sundries area, so that gear and rack are easy to dislocate, and then gear or rack is easy to be damaged, and the use experience is poor. UTILITY MODEL CONTENTS

[0005] In order to solve the above problems, the utility model provides a kind of outer-embedded base guide rail guiding structure.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an externally embedded base guide rail structure, including a guide rail, a rack mounted on the guide rail, a gear meshing with the rack, a drive motor fixed to the gear, a sliding plate fixed to the drive motor, two support wheel assemblies symmetrically mounted on the sliding plate, an eccentric shaft set on the sliding plate, and a guide bearing connected to the eccentric shaft. Two mutually symmetrical mounting plates are fixed on both sides of the bottom surface of the sliding plate. Rotation holes are opened on the side walls of the two opposite mounting plates that are close to each other. A cleaning assembly for cleaning the upper surface of the guide rail is provided on the mounting plate.

[0007] By adopting the above technical solution, this utility model achieves clearance adjustment between the guide bearing and the guide rail through an eccentric shaft, thereby ensuring a sliding fit between the guide bearing and the guide rail. With this structure, when the operator needs to drive the sliding plate, they only need to turn on the drive motor, causing the output shaft of the drive motor to rotate. This causes the gear to follow the rotation of the drive motor's output shaft, thus moving the sliding plate along the extension direction of the rack under the action of the gear. During this process, the operator can adjust the height of the cleaning plate by rotating the rotating rod. When the sliding plate moves along the extension direction of the guide rail, the cleaning plate cleans the upper surface of the guide rail, thereby reducing the probability of impurities moving directly below the support wheel assembly, thus reducing the probability of the sliding plate's height changing during movement, and consequently reducing the probability of gear damage due to misalignment.

[0008] Furthermore, the cleaning assembly includes a rotating rod rotatably disposed within a rotating hole, a cleaning plate fixed to the side wall of the rotating rod, and a limiting device disposed on a sliding plate for limiting the position of the cleaning plate.

[0009] Furthermore, a torsion spring is fixed on one side wall of the rotating rod, and the other end of the torsion spring is fixed on the inner wall of the corresponding rotating hole.

[0010] By adopting the above technical solution, when the operator needs to move the sliding plate, they need to close the limiting device, which will allow the rotating rod to automatically rotate downwards under the action of the torsion spring, thereby automatically moving the bottom surface of the cleaning plate to the lowest point and adjusting the height of the cleaning plate. When the cleaning plate moves to the lowest point, the operator needs to open the limiting device to keep the cleaning plate stable. At this time, when the sliding plate moves, the cleaning plate follows the sliding plate and cleans the upper surface of the guide rail, thereby reducing the probability of impurities entering the support assembly.

[0011] Furthermore, the limiting device includes a threaded rod threadedly connected to the side wall of the mounting plate away from the torsion spring and a screwing block fixed to the side wall of the threaded rod away from the rotating rod, with one end of the threaded rod away from the screwing block extending into the rotating hole.

[0012] By adopting the above technical scheme, when the cleaning plate moves to the lowest point, the worker needs to rotate the twisting block, so that the threaded rod rotates with the twisting block, the end of the threaded rod abuts against the rotating rod, and the rotating rod is kept stable under the action of the threaded rod, so that the cleaning plate is kept stable, thereby reducing the probability of position change of the cleaning plate under the action of external force.

[0013] Further, the upper surface of the cleaning plate is embedded with a first magnet block, the bottom surface of the sliding plate is embedded with a second magnet block on both sides, and the first magnet block and the second magnet block are mutually adsorbed.

[0014] By adopting the above technical scheme, when the worker needs to overhaul the guide bearing and the like, the worker only needs to close the limiting device and rotate the cleaning plate upward, so that the first magnet block gradually approaches the second magnet block, the first magnet block and the second magnet block are mutually adsorbed, the cleaning plate is kept stable under the action of the second magnet block, and the probability of interference of the cleaning plate to the overhaul work of the worker is reduced.

[0015] Further, the side wall of the cleaning plate away from the rotating rod is provided with a round corner, and the round corner surface of the cleaning plate is provided with a silica gel sheet.

[0016] Further, the bottom surface of the cleaning plate is provided with a ball for adjusting the height of the cleaning plate.

[0017] By adopting the above technical scheme, when the bottom surface of the cleaning plate moves to the lowest point under the action of the torsion spring, a certain gap is left between the bottom surface of the cleaning plate and the upper surface of the guide rail, so that the probability of continuous friction between the cleaning plate and the upper surface of the guide rail in the moving process of the sliding plate is reduced, noise is reduced, and the service life of the cleaning plate is prolonged. At the same time, the silica gel sheet improves the cleaning effect of the cleaning plate on large particles, thereby improving the use experience of the worker.

[0018] Further, the side wall of the threaded rod away from the twisting block is provided with a rubber block.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1、In the application, the eccentric shaft is used to realize the gap adjustment between the guide bearing and the guide rail, so as to ensure the sliding fit between the guide bearing and the guide rail. When the staff needs to drive the sliding plate, the staff only needs to start the driving motor, so that the output shaft of the driving motor rotates, so that the gear rotates with the output shaft of the driving motor, and then the sliding plate moves along the extension direction of the rack under the action of the gear. In this process, the staff needs to rotate the rotating rod, so as to adjust the height of the cleaning plate. When the sliding plate moves along the extension direction of the guide rail, the cleaning plate cleans the upper surface of the guide rail, thereby reducing the probability that the impurities move to the position directly below the support wheel assembly, thereby reducing the probability that the height of the sliding plate changes during the movement, thereby reducing the probability that the gear is damaged due to misalignment;

[0021] 2、In the application, when the staff needs to move the sliding plate, the staff needs to close the limiting device, so that the rotating rod automatically rotates downward under the action of the torsional spring, so that the bottom surface of the cleaning plate automatically moves to the lowest point, thereby adjusting the height of the cleaning plate. When the cleaning plate moves to the lowest point, the staff needs to open the limiting device, so that the cleaning plate remains stable. At this time, when the sliding plate moves, the cleaning plate moves with the sliding plate and cleans the upper surface of the guide rail, thereby reducing the probability that the impurities enter the position below the support wheel assembly;

[0022] 3、In the application, when the cleaning plate moves to the lowest point, the staff needs to rotate the twisting block, so that the threaded rod rotates with the twisting block, so that the end of the threaded rod abuts against the rotating rod, thereby making the rotating rod stable under the action of the threaded rod, so that the cleaning plate remains stable, thereby reducing the probability that the position of the cleaning plate changes under the action of external force.

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] like Figures 1-5 As shown in the figure, this application discloses an externally mounted base guide rail structure, including a guide rail 1, a rack 11, a gear 2, a drive motor 21, a sliding plate 3, a support wheel assembly 31, an eccentric shaft 4, a guide bearing 41, a mounting plate 5, a cleaning assembly 6, a torsion spring 8, a first magnet 81, a second magnet 82, a ball bearing 84, and a rubber block 9. The rack 11 is mounted on the guide rail 1, and the gear 2 meshes with the rack 11. The output shaft of the drive motor 21 is fixed to the gear 2. The sliding plate 3 is a rectangular plate structure, and the sliding plate 3 is fixed to the drive motor 21. Two support wheel assemblies 31 are provided and symmetrically mounted on the sliding plate 3. The eccentric shaft 4 is disposed on the sliding plate 3, and the guide bearing 41 is connected to the eccentric shaft 4. The mounting plate 5 is a rectangular plate structure, and four mounting plates 5 are provided and symmetrically fixed to the bottom sides of the sliding plate 3 in pairs. Rotation holes 51 are provided on the side walls of the two adjacent mounting plates 5.

[0031] The cleaning assembly 6 is mounted on the mounting plate 5 and is used to clean the upper surface of the guide rail 1. The cleaning assembly 6 includes a rotating rod 61, a cleaning plate 62, and a limiting device 7. The rotating rod 61 is a round rod structure and is rotatably mounted in the rotating hole 51. The cleaning plate 62 is a plate structure and is fixed to the side wall of the rotating rod 61. One end of the torsion spring 8 is fixed to the side wall of one side of the rotating rod 61, and the other end of the torsion spring 8 is fixed to the inner wall of the corresponding rotating hole 51.

[0032] When the worker needs to move the sliding plate 3, the worker needs to close the limiting device 7, so that the rotating rod 61 is automatically rotated downward under the action of the torsional spring 8, thereby the bottom surface of the cleaning plate 62 is automatically moved to the lowest point, and the height of the cleaning plate 62 is adjusted. When the cleaning plate 62 is moved to the lowest point, the worker needs to open the limiting device 7, so that the cleaning plate 62 is kept stable. At this time, when the sliding plate 3 moves, the cleaning plate 62 moves with the sliding plate 3 and cleans the upper surface of the guide rail 1, thereby reducing the probability of impurities entering the lower part of the support assembly.

[0033] The limiting device 7 is arranged on the sliding plate 3 and used for limiting the cleaning plate 62. The limiting device 7 comprises a threaded rod 71 and a rotating block 72. The threaded rod 71 is threadedly connected to the side wall of the mounting plate 5 away from the torsional spring 8. The threaded rod 71 extends to the rotating hole 51 away from the rotating block 72. The rotating block 72 is in a block structure. The rotating block 72 is fixed to the side wall of the threaded rod 71 away from the rotating rod 61.

[0034] When the cleaning plate 62 is moved to the lowest point, the worker needs to rotate the rotating block 72, so that the threaded rod 71 is rotated with the rotating block 72, thereby the end of the threaded rod 71 abuts against the rotating rod 61, and the rotating rod 61 is kept stable under the action of the threaded rod 71, thereby the cleaning plate 62 is kept stable, and the probability of the position of the cleaning plate 62 changing under the action of external force is reduced.

[0035] The first magnet block 81 is in a block structure and is embedded in the upper surface of the cleaning plate 62. The second magnet block 82 is in a block structure and is arranged on the bottom surface of the sliding plate 3. The first magnet block 81 and the second magnet block 82 are mutually adsorbed. When the worker needs to overhaul the guide bearing 41 and other devices, the worker only needs to close the limiting device 7 and rotate the cleaning plate 62 upward, so that the first magnet block 81 gradually approaches the second magnet block 82, thereby the first magnet block 81 and the second magnet block 82 are mutually adsorbed, and the cleaning plate 62 is kept stable under the action of the second magnet block 82, thereby the probability of the cleaning plate 62 interfering with the overhaul work of the worker is reduced.

[0036] The side wall of the cleaning plate 62 away from the rotating rod 61 is provided with a rounded corner. The silica gel sheet 83 is in a sheet structure and is arranged on the rounded corner surface of the cleaning plate 62. The ball 84 is in a spherical structure and is arranged on the bottom surface of the cleaning plate 62 in a plurality of manners and is used for adjusting the height of the cleaning plate 62.

[0037] When the bottom surface of the cleaning plate 62 is moved to the lowest point under the action of the torsion spring 8, a certain gap is left between the bottom surface of the cleaning plate 62 and the upper surface of the guide rail 1, thereby reducing the probability that the cleaning plate 62 continuously rubs against the upper surface of the guide rail 1 during the movement of the sliding plate 3, further reducing the generation of noise, and being beneficial to prolonging the service life of the cleaning plate 62. Meanwhile, the setting of the silica gel sheet 83 improves the cleaning effect of the cleaning plate 62 on large-particle impurities, thereby improving the use experience of the workers.

[0038] The rubber block 9 is in a block structure, and the rubber block 9 is arranged on the side wall of the threaded rod 71 away from the twisting block 72.

[0039] The use principle of the one kind of externally embedded base guide rail 1 guiding structure in the embodiment is that the eccentric shaft 4 is used to adjust the gap between the guide bearing 41 and the guide rail 1, so as to ensure the sliding fit between the guide bearing 41 and the guide rail 1. When the worker needs to drive the sliding plate 3, the worker only needs to start the driving motor 21, so that the output shaft of the driving motor 21 rotates, so that the gear 2 rotates with the output shaft of the driving motor 21, and then the sliding plate 3 moves along the extension direction of the rack 11 under the action of the gear 2. In this process, the worker needs to rotate the rotating rod 61, so as to adjust the height of the cleaning plate 62. When the sliding plate 3 moves along the extension direction of the guide rail 1, the cleaning plate 62 cleans the upper surface of the guide rail 1, thereby reducing the probability that the impurities move to the position directly below the supporting wheel assembly 31, further reducing the probability that the height of the sliding plate 3 changes during the movement, thereby reducing the probability that the gear 2 is damaged due to misalignment.

[0040] The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited to the above-mentioned embodiments. Any technical scheme falling within the idea of the utility model belongs to the protection scope of the utility model. It should be noted that for ordinary technical personnel in the technical field, some improvements and decorations without departing from the principle of the utility model are also regarded as the protection scope of the utility model.
