Description

Technical Field

[0001] This utility model relates to the field of hollow rotating platforms, specifically an inductive hollow rotating platform. Background Technology

[0002] The hollow rotary platform is a new type of speed reducer product. Different output speeds can be obtained according to different reduction ratios, making it suitable for various rotary motion applications. It can replace DD motors and cam dividers, achieving a balance between the two. Repeat positioning accuracy is ≤5 seconds, the motor is easily configured, it has a stable load capacity, and can be paired with AC servo motors or stepper motors for arbitrary angle division. It can satisfy digital control requirements that dividers cannot achieve, while maintaining positioning accuracy comparable to DD motors.

[0003] The existing device has the following shortcomings when in use: the induction hollow rotary platform adds lubricant to reduce wear and prevent rust. When the lubricating oil becomes obviously cloudy after a period of use, it needs to be replaced. The viscosity of the oil increases after cooling. The lubricating oil on the gear ring usually needs to be cleaned and replaced by disassembling the outer shell. After that, the hollow rotary platform is reassembled, which is time-consuming and laborious, making the lubricating oil replacement of the hollow rotary platform inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide an inductive hollow rotating platform to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an induction-type hollow rotating platform, comprising a housing shell, a rotating platform, a fixed bearing, a gear ring, a mounting box, an oil level window, and an oil cleaning rod. The housing shell has a mounting groove. The bottom of the rotating platform is fitted with a gear ring via fixing bolts. The fixed bearing is rotatably mounted on the rotating platform. A wiring window is provided on the fixed bearing. The rotating platform is placed in the mounting groove. The housing shell is connected to the fixed bearing via fixing screws. An oil level window is provided on the housing shell and communicates with the mounting groove. An oil level plug is installed at the oil level window. The oil cleaning rod passes through the oil level window and fits against the gear ring. The oil cleaning rod is semi-cylindrical, and one side of the oil cleaning rod is a thin sheet made of silicone.

[0006] Using the above technical solution, a rotating platform is placed in the mounting groove on the outer shell of the housing. The gear ring at the bottom of the rotating platform meshes with the gear driven by the drive motor, and is fixedly installed on the rotating platform with the housing shell, allowing the rotating platform to rotate circumferentially between the housing shell and the fixed bearing. When the lubricating oil of the induction hollow rotating platform becomes noticeably cloudy after a period of use, the oil level plug installed at the oil level window on the housing shell is removed, and then an oil level cleaning rod is inserted into the oil level window, making the oil level cleaning rod a thin sheet. The side of the cleaning rod abuts against the toothed ring. The thin, elastic side of the cleaning rod is made of silicone and can enter the gaps between the teeth on the toothed ring to scrape off the viscous lubricating oil. Because the cleaning rod is semi-cylindrical, the scraped lubricating oil will flow down along the central pipe and be discharged. After cleaning, new lubricating oil can be added. When the lubricating oil of the induction hollow rotary platform becomes obviously cloudy after a period of use, it avoids the problem of having to disassemble the outer shell to clean and replace the lubricating oil on the toothed ring when changing the lubricating oil, making the replacement of lubricating oil for the hollow rotary platform time-saving and labor-saving.

[0007] Preferably, an installation box is installed on the outer shell of the housing, and a drive motor is installed in the installation box. The power shaft end of the drive motor is connected to a gear installed in the installation slot, and the gear meshes with a gear ring.

[0008] Using the above technical solution, by starting the drive motor installed in the mounting box, the gear connected to the drive motor's power shaft is driven to rotate, and the gear meshes with the gear ring, thereby causing the rotating platform to rotate circumferentially.

[0009] Preferably, a sensor plate is installed on the outer ring wall of the rotating platform, and a sensor is installed on the mounting box.

[0010] By adopting the above technical solution, the hollow rotating platform is equipped with sensing operation through the sensing plate installed on the outer ring wall of the rotating platform and the sensor installed on the mounting box.

[0011] Preferably, a circular track is provided on the mounting groove, and a connecting slider is installed at the bottom of the toothed ring, the connecting slider being slidably connected to the circular track.

[0012] By adopting the above technical solution, the connecting slider installed at the bottom of the gear ring is slidably connected to the circular track through the circular track opened on the mounting groove, which ensures the stability of the gear ring during rotation and also improves the stability of the circumferential rotation of the rotating platform.

[0013] Preferably, a fixing oil seal ring is installed on the outer shell of the housing, and a wear-resistant sealing ring is installed on the inner ring wall of the fixing oil seal ring.

[0014] By adopting the above technical solution, the sealing performance of the induction hollow rotary platform is increased by using a fixed oil seal ring installed on the outer shell of the housing, in conjunction with a wear-resistant sealing ring installed on the inner ring wall of the fixed oil seal ring.

[0015] Preferably, the rotating platform is provided with positioning holes, and a fixing plate is installed on the outer shell of the box.

[0016] Using the above technical solution, the processing equipment to be assembled is connected to the rotating platform through the positioning holes set on the rotating platform, and the induction hollow rotating platform is installed on the mechanical equipment to be used through the fixing plate installed on the outer shell of the box.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: When the lubricating oil of the induction hollow rotary platform becomes significantly cloudy after a period of use, the oil level plug installed at the oil level window on the outer shell of the housing can be removed. Then, an oil cleaning rod can be inserted into the oil level window, with one thin, flat side of the oil cleaning rod abutting against the toothed ring. The thin, flat side of the oil cleaning rod is made of elastic silicone material, which can enter the gaps between the teeth on the toothed ring to scrape off the viscous lubricating oil. Because the oil cleaning rod is semi-cylindrical, the scraped lubricating oil will flow downwards along the central pipe and be discharged. After cleaning, new lubricating oil can be added. When the lubricating oil of the induction hollow rotary platform becomes significantly cloudy after a period of use, the problem of having to disassemble the outer shell to clean and replace the lubricating oil on the toothed ring when changing the lubricating oil is avoided, making the replacement of the lubricating oil of the hollow rotary platform time-saving and labor-saving.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Please see Figure 1-4 This utility model provides an embodiment of an inductive hollow rotating platform, comprising a housing 1, a rotating platform 3, a fixed bearing 4, a gear ring 7, a mounting box 12, an oil level window 20, and an oil cleaning rod 21. The housing 1 has a mounting groove 2. The bottom of the rotating platform 3 is fitted with a gear ring 7 via fixing bolts 10. The fixed bearing 4 is rotatably mounted on the rotating platform 3. The fixed bearing 4 has a wiring window 5. The rotating platform 3 is placed in the mounting groove 2. The housing 1 is connected to the fixed bearing 4 via fixing screws 6. The housing 1 has an oil level window 20 that communicates with the mounting groove 2. An oil level plug is installed at the oil level window 20. The oil cleaning rod 21 passes through the oil level window 20 and fits against the gear ring 7. The oil cleaning rod 21 is semi-cylindrical, and one side of the oil cleaning rod 21 is a thin sheet made of silicone. A rotating platform 3 is placed in the mounting groove 2 on the outer casing 1. The gear ring 7 at the bottom of the rotating platform 3 meshes with the gear 13 driven by the drive motor 14, and is fixedly installed on the outer casing 1 with the fixed bearing 4 rotatably mounted on the rotating platform 3. This allows the rotating platform 3 to rotate circumferentially between the outer casing 1 and the fixed bearing 4. When the lubricating oil of the induction hollow rotating platform becomes noticeably cloudy after a period of use, the oil level plug installed at the oil level window 20 on the outer casing 1 is removed. Then, an oil level cleaning rod 21 is inserted into the oil level window 20 to clean the oil level. The thin, sheet-like side of the oil cleaning rod 21 abuts against the toothed ring 7. The thin, sheet-like side of the oil cleaning rod 21 is made of elastic silicone material, which can enter the gaps between the teeth on the toothed ring 7 to scrape off the viscous lubricating oil. Because the oil cleaning rod 21 is semi-cylindrical, the scraped lubricating oil will flow downwards along the central pipe and be discharged. After cleaning, new lubricating oil is added. When the lubricating oil of the induction hollow rotary platform becomes obviously cloudy after a period of use, the problem of having to disassemble the outer shell to clean and replace the lubricating oil on the toothed ring is avoided, making the replacement of the lubricating oil of the hollow rotary platform time-saving and labor-saving.

[0025] A mounting box 12 is installed on the outer shell 1 of the housing. A drive motor 14 is installed in the mounting box 12. The drive shaft of the drive motor 14 is connected to a gear 13 installed in the mounting slot 2. The gear 13 meshes with the gear ring 7. By starting the drive motor 14 installed in the mounting box 12, the gear 13 connected to the drive shaft of the drive motor 14 is driven to rotate. The gear 13 meshes with the gear ring 7, thereby causing the rotating platform 3 to rotate circumferentially.

[0026] A sensing plate 16 is installed on the outer ring wall of the rotating platform 3, and a sensor 15 is installed on the mounting box 12. Through the sensing plate 16 installed on the outer ring wall of the rotating platform 3, and the sensor 15 installed on the mounting box 12, the hollow rotating platform is equipped with sensing capabilities. The sensing electronic equipment involved in this application is existing mature technology, with many products on the market. These are all general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional use. The scope of protection of this application does not involve improvements to the software and methods, so they are not described in detail here.

[0027] A circular track 9 is provided on the mounting groove 2, and a connecting slider 8 is installed at the bottom of the toothed ring 7. The connecting slider 8 is slidably connected to the circular track 9. The circular track 9 on the mounting groove 2 allows the connecting slider 8 installed at the bottom of the toothed ring 7 to be slidably connected to the circular track 9, ensuring the stability of the toothed ring 7 during rotation and improving the stability of the circumferential rotation of the rotating platform 3.

[0028] A fixed oil seal ring 17 is installed on the outer shell 1 of the housing, and a wear-resistant sealing ring 18 is installed on the inner ring wall of the fixed oil seal ring 17. The fixed oil seal ring 17 installed on the outer shell 1 of the housing, together with the wear-resistant sealing ring 18 installed on the inner ring wall of the fixed oil seal ring 17, increases the sealing performance of the induction hollow rotary platform.

[0029] The rotating platform 3 is provided with positioning holes 11, and the outer shell 1 is equipped with a fixing plate 19. The processing equipment to be assembled is connected to the rotating platform 3 through the positioning holes 11, and the induction hollow rotating platform is installed on the mechanical equipment to be used through the fixing plate 19 installed on the outer shell 1.

[0030] Working principle: A rotating platform 3 is placed in the mounting groove 2 on the outer shell 1. A circular track 9 on the mounting groove 2 allows the connecting slider 8 on the bottom gear ring 7 of the rotating platform 3 to slide smoothly into the circular track 9, ensuring the stability of the gear ring 7 during rotation and improving the stability of the rotating platform 3's circumferential rotation. Then, the fixed bearing 4, rotatably mounted on the rotating platform 3, is fixedly installed to the outer shell 1. A fixed oil seal ring 17 installed on the outer shell 1, along with a wear-resistant sealing ring 18 installed on the inner ring wall of the fixed oil seal ring 17, increases the sealing performance of the induction-type hollow rotating platform. Starting the drive motor 14 drives the gear 13 connected to its power shaft to rotate. The gear 13 meshes with the gear ring 7, causing the rotating platform 3 to rotate circumferentially between the outer shell 1 and the fixed bearing 4. When the induction-type hollow rotating platform 3 rotates, the platform rotates continuously. When the lubricating oil of the hollow rotary platform becomes noticeably cloudy after a period of use, remove the oil level plug installed at the oil level window 20 on the outer casing 1. Then, insert the cleaning rod 21 into the oil level window 20, so that the thin, flat side of the cleaning rod 21 abuts against the toothed ring 7. The thin, flat side of the cleaning rod 21 is made of elastic silicone material, which can enter the gaps between the teeth on the toothed ring 7 to scrape off the viscous lubricating oil. Because the cleaning rod 21 is semi-cylindrical, the scraped lubricating oil will flow down along the central pipe and be discharged. After cleaning, new lubricating oil can be added. When the lubricating oil of the induction hollow rotary platform becomes noticeably cloudy after a period of use, the problem of having to disassemble the outer casing to clean and replace the lubricating oil on the toothed ring is avoided, making the replacement of the lubricating oil of the hollow rotary platform time-saving and labor-saving.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
