Description

Technical Field

[0001] This utility model belongs to the field of machining technology, specifically relating to a single-row internal gear slewing bearing tooling. Background Technology

[0002] Slewing bearings play a vital role in the construction machinery industry. Internal gear slewing bearings are one of the most common and widely used types of slewing bearings in engineering equipment. To improve the machining efficiency of internal gears, multiple slewing bearing gear rings are stacked during milling. Existing tooling uses two locating pins and a rounding assembly to round the slewing bearing gear rings. However, this method requires operators to rotate multiple rounding assemblies individually, which affects the rounding efficiency. Furthermore, it requires locating pins of various sizes to accommodate slewing bearing gear rings of different sizes. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention achieves synchronous rotation of several planetary gears by setting up a gear ring, an electric gear, and planetary gears. The planetary gears are connected to the rounding mechanism via connecting rods. The synchronous rotation of the planetary gears enables the synchronous activation of several rounding mechanisms, which in turn enable the device to round the slewing bearing gear ring. This allows the device to be applied to slewing bearing gear rings of different sizes. The connecting sleeve is connected to several rotating sleeves through the cooperation of a spur gear set, a mounting shaft, and several bevel gear sets. When the connecting sleeve rotates, all the rotating sleeves mounted on the storage box rotate synchronously, thereby achieving synchronous movement of the threaded push rod and improving the efficiency of the device in rounding. By setting two support rods through one end of the threaded push rod on the rotating sleeve, relative rotation between the rotating sleeve and the threaded push rod is prevented, ensuring the working effect of the threaded push rod.

[0014] Please see Figure 1-5 This utility model provides the following technical solution: a single-row internal gear slewing bearing tooling, including a storage frame 1, a rounding mechanism 3, an annular frame 4, and a mounting base 5. A gear ring 41 and an electric gear 42 meshing with the gear ring 41 are installed inside the annular frame 4. Three connecting shafts 44 are evenly installed inside the annular frame 4. Planetary gears 43 meshing with the gear ring 41 are installed on the connecting shafts 44. A connecting sleeve 31 that cooperates with the connecting shafts 44 is rotatably installed on the storage frame 1. A storage box 33 with a position corresponding to the connecting sleeve 31 is provided on the storage frame 1. An mounting shaft 35 and several rotating sleeves 37 are rotatably installed on the storage box 33. A threaded push rod 32 is installed inside the rotating sleeve 37. The threaded push rod 32 is threadedly installed on the threaded groove on the side wall of the storage box 33. The connecting sleeve 31 and the mounting shaft 35 are connected by a spur gear set 34. The mounting shaft 35 and the rotating sleeve 37 are connected by a bevel gear set 36.

[0015] The storage frame 1 is used to store the slewing bearing gear ring to be processed. The top surface of the storage frame 1 has a lifting hole for easy user movement of the device. The bottom of the storage frame 1 has an annular protrusion for supporting the slewing bearing gear ring. The gear ring 41 is rotatably installed inside the annular frame 4. The electric gear 42 meshes with the external gear of the gear ring 41. When the electric gear 42 starts, the gear ring 41 begins to rotate under its drive. The planetary gear 43 meshes with the internal gear of the gear ring 41. When the gear ring 41 rotates, the planetary gear 43 is driven to rotate by the rotating gear ring 41. The rotating planetary gear 43 drives the connecting shaft 44 to rotate. The three planetary gears 43 inside the annular frame 4 mesh with the gear ring 41, and the rotation of the gear ring 41 achieves... The three planetary gears 43 rotate synchronously. The connecting sleeve 31 is positioned corresponding to the connecting shaft 44. When the annular frame 4 is placed on top of the storage frame 1, the connecting shaft 44 enters the interior of the connecting sleeve 31. The inner wall of the connecting sleeve 31 has a protrusion, and the bottom surface of the connecting shaft 44 has a groove that mates with the inner protrusion of the connecting sleeve 31. The connecting sleeve 31 and the connecting shaft 44 are connected together through the engagement of the inner protrusion of the connecting sleeve 31 and the bottom groove of the connecting shaft 44. The engagement of the inner protrusion of the connecting sleeve 31 and the bottom groove of the connecting shaft 44 serves as a limiting action, ensuring that the connecting shaft 44 rotates along with the connecting sleeve 31. The three connecting shafts 44 rotate synchronously under the drive of the three planetary gears 43. The connecting shaft 44 rotates synchronously with the connecting sleeve 31. When the connecting sleeve 31 rotates, its power is transmitted to the mounting shaft 35 via the spur gear set 34. The mounting shaft 35 is then rotated by the connecting sleeve 31. The rotating sleeve 37 is rotatably mounted on the storage box 33. The mounting shaft 35 is equipped with a bevel gear set 36 connected to the rotating sleeve 37. When the mounting shaft 35 rotates, its power is transmitted to the rotating sleeve 37 via the bevel gear set 36. The rotating sleeve 37 is then rotated by the mounting shaft 35. When the rotating sleeve 37 rotates, the threaded push rod 32 rotates along the threaded groove of the mounting threaded push rod 32 on the storage box 33 under the action of the thread. The position of the threaded push rod 32 is adjusted. An array of bevel gears 36 connected to the rotating sleeves 37 is mounted on the mounting shaft 35, enabling synchronous rotation of the several rotating sleeves 37 mounted on the storage box 33. The synchronous rotation of the rotating sleeves 37 allows for synchronous movement of the threaded push rods 32 mounted on the storage box 33. Driven by the connecting shaft 44, the synchronously rotating connecting sleeves 31 enable synchronous movement of the threaded push rods 32 mounted on the three storage boxes 33. The moving threaded push rods 32 actuate the slewing bearing gear ring, thus adjusting its position. When the three sets of threaded push rods 32, evenly distributed on the storage frame 1, move synchronously, the slewing bearing gear ring moves to the center position of the storage frame 1 under the actuation of the threaded push rods 32.At this point, the center of the slewing bearing gear ring overlaps with the center of the storage frame 1, achieving the roundness calibration of the slewing bearing gear ring by the device. The calibration method ensures that the slewing bearing gear rings stacked inside the storage frame 1 are simultaneously actuated by the threaded push rod 32, achieving synchronous adjustment of the positions of several slewing bearing gear rings and improving the efficiency of the device in calibrating the slewing bearing gear rings. The connection method between the connecting shaft 44 and the calibration mechanism 3 ensures that the user can easily separate the connecting shaft 44 and the calibration mechanism 3 by removing the annular frame 4 from the storage frame 1, preventing the annular frame 4 from obstructing the machining of the slewing bearing gear rings by the machining device. It also prevents damage to the gear ring 41, electric gear 42, and planetary gear 43 during machining of the slewing bearing gear rings. Power is transmitted through the spur gear set 34 and bevel gear set 36, increasing the force required for the threaded push rod 32 to rotate and ensuring the stability of the threaded push rod 32 during device use.

[0016] Specifically, two support rods are installed on the inner wall of the rotating sleeve 37, one end of each threaded push rod 32.

[0017] The two inner wall support rods of the rotating sleeve 37 and the groove through which the threaded push rod 32 is inserted serve as a limiting mechanism, ensuring that the threaded push rod 32 does not rotate relative to the rotating sleeve 37 during its rotation. This ensures that the threaded push rod 32 can smoothly extend out of the storage box 33 during the rotation of the rotating sleeve 37, thereby ensuring that the moving distance of all the threaded push rods 32 is the same and ensuring the working effect of the rounding mechanism 3.

[0018] Specifically, the top of the side wall of the groove of the mounting sleeve 31 of the storage frame 1 is provided with a limiting ring, and the top surface of the limiting ring is an inwardly inclined slope.

[0019] The top limiting ring of the connecting sleeve 31 serves as a limit, ensuring the stability of the connecting sleeve 31 during rotation. When the user separates the connecting shaft 44 and the connecting sleeve 31, the limiting ring can prevent the connecting shaft 44 from moving along with the connecting sleeve 31 during the movement. The top surface shape of the limiting ring serves as a guide, making it easier for the user to install the connecting shaft 44 onto the connecting sleeve 31.

[0020] Specifically, the top surface of the storage frame 1 is provided with several mounting grooves 11 that cooperate with the mounting base 5. The top plate of the clamping column 53 is slidably mounted on the top threaded rod of the mounting base 5. A threaded sleeve 54 that cooperates with the threaded rod is rotatably mounted on the top plate of the clamping column 53. A T-shaped groove 51 is provided on the side wall of the mounting groove 11. A T-shaped block 52 that cooperates with the T-shaped groove 51 is slidably mounted inside the mounting base 5. A threaded rod is rotatably mounted on the groove of the T-shaped block 52. The T-shaped block 52 is mounted on the threaded rod by threads.

[0021] Mounting slot 11 is used to install mounting base 5. When the user rotates the threaded rod on the slot of mounting T-block 52, T-block 52 moves along the threaded rod under the action of the thread, thereby adjusting the position of T-block 52. T-slot 51 is provided on the side wall of mounting slot 11. During the movement of T-block 52, T-block 52 enters T-slot 51. The cross-sectional shape of T-slot 51 is T-shaped. The cooperation between T-slot 51 and T-block 52 serves as a limiting function, ensuring the stability of mounting base 5 after it is installed on mounting slot 11. Threaded sleeve 54 is threaded onto the top threaded rod of mounting base 5. When threaded sleeve 54 rotates, it moves along the top threaded rod of mounting base 5 under the action of the thread, thereby adjusting the position of threaded sleeve 54. Threaded sleeve 54 is rotatably mounted on the top of clamping column 53. On the plate, the threaded sleeve 54 moves along with the clamping column 53. During the movement of the clamping column 53, it contacts the slewing bearing gear ring stacked in the storage frame 1, thus fixing the slewing bearing gear ring and ensuring its stability during processing. The threaded sleeve 54 is rotatably mounted on the clamping column 53, ensuring that the rotating threaded sleeve 54 does not rotate along with the clamping column 53. The top surface of the mounting base 5 is provided with a support rod that penetrates the top plate of the clamping column 53. The cooperation between the top support rod of the mounting base 5 and the groove through which the support rod penetrates the clamping column 53 serves as a limit, ensuring that the clamping column 53 does not rotate during movement and thus ensuring its stability. The bottom surface of the clamping column 53 is provided with a rubber pad to reduce damage to the clamping column 53 during the processing of the slewing bearing gear ring.

[0022] Specifically, the bottom surface of the annular frame 4 is provided with a protrusion that mates with the mounting groove 11.

[0023] The cooperation between the bottom protrusion of the ring frame 4 and the mounting groove 11 improves the stability of the ring frame 4 after it is installed on the storage frame 1. The cooperation between the bottom protrusion of the ring frame 4 and the mounting groove 11 also plays a limiting role, reducing the force on the connection between the connecting sleeve 31 and the connecting shaft 44, and extending the service life of the connecting sleeve 31 and the connecting shaft 44.

[0024] Specifically, the bottom surface of the annular frame 4 is provided with a mounting frame that cooperates with the motor of the electric gear 42, and the side wall of the storage frame 1 is provided with a groove that cooperates with the bottom mounting frame of the annular frame 4.

[0025] The bottom mounting frame of the annular frame 4 is used to accommodate the motor of the electric gear 42. The position of the motor of the electric gear 42 ensures that the connecting shaft 44 and the motor of the electric gear 42 are located on the same side of the annular frame 4. When the user stores the annular frame 4, the side of the annular frame 4 with the motor of the connecting shaft 44 and the electric gear 42 faces upward, reducing the damage to the connecting shaft 44 and the motor of the electric gear 42 during the storage of the device. The cooperation between the groove on the top surface of the storage frame 1 and the mounting frame that accommodates the motor of the electric gear 42 plays a guiding role, making it easier for the user to determine the position of the annular frame 4 on the storage frame 1, thus improving the efficiency of the user in installing the annular frame 4.

[0026] Specifically, the bottom of the storage box 1 is provided with several fixed bases 2, and the fixed bases 2 are provided with stepped grooves.

[0027] The fixed base 2 is used to fix the device on the processing device. When fixing the device, the screw is moved into the stepped groove of the fixed base 2, and the nut is installed on the threaded rod located inside the fixed base 2. The fixed base 2 is fixed by the cooperation between the nut and the side wall of the stepped groove of the fixed base 2. The device is fixed on the processing device.

[0028] The working principle and usage process of this utility model are as follows: The slewing bearing gear ring is placed on the storage frame 1. The ring frame 4 is installed on the storage frame 1 through the cooperation of the bottom protrusion of the ring frame 4 and the mounting groove 11, and the cooperation of the top groove of the storage frame 1 and the bottom mounting frame of the ring frame 4. At this time, the connecting shaft 44 enters the interior of the connecting sleeve 31. The connecting shaft 44 and the connecting sleeve 31 are connected together through the cooperation of the inner wall protrusion of the connecting sleeve 31 and the end face groove of the connecting shaft 44. The electric gear 42 is activated, and the gear ring 41 is rotated by the electric gear 42. The rotating gear ring 41 rotates the planetary gear 43. The rotating planetary gear 43 rotates the connecting sleeve 31 through the connecting shaft 44. The rotating connecting sleeve 31 rotates the mounting shaft 35 through the spur gear set 34. The rotating mounting shaft 35 rotates the rotating sleeve 37 through the bevel gear set 36. The rotating sleeve 37 rotates the threaded push rod 3. 2. The rotating threaded push rod 32 moves along the threaded groove of the mounting threaded push rod 32 under the action of the thread. The moving threaded push rod 32 will push the slewing bearing gear ring, realizing the rounding mechanism 3 to round the slewing bearing gear ring. After the rounding is completed, the ring frame 4 is removed from the storage frame 1, and the mounting seat 5 is installed on the mounting groove 11. The threaded rod with the T-shaped block 52 is rotated. The T-shaped block 52 moves along the threaded rod under the action of the thread. The moving T-shaped block 52 enters the T-shaped groove 51. The mounting seat 5 is fixed on the mounting groove 11 through the cooperation of the T-shaped groove 51 and the T-shaped block 52. The threaded sleeve 54 is rotated. The threaded sleeve 54 moves along the threaded rod on the top surface of the mounting seat 5 under the action of the thread. The moving clamping column 53 contacts the slewing bearing gear ring, and the slewing bearing gear ring is fixed. The device is fixed on the processing device through the cooperation of the fixed base 2, nut and threaded rod.
