Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, and in particular to a gear hobbing machine for machining motor gear shafts. Background Technology

[0002] The motor gear shaft is a key connecting component between the motor and the transmission system, serving both power transmission and precise speed change functions. Its structure is typically forged from high-precision alloy steel, with gear teeth machined onto the shaft body using a special process. The surface is carburized and quenched to improve hardness and wear resistance. One end of the shaft is connected to the motor rotor, inputting the motor's rotational power, while the other end engages with other transmission components through gear meshing to complete the conversion of speed and torque. In equipment such as industrial robots and CNC machine tools, the motor gear shaft ensures efficient operation of the equipment due to its stable power transmission and reliable mechanical performance.

[0003] In the prior art, a gear hobbing machine is required for grinding when producing motor gear shafts. The grinding mechanism in traditional gear hobbing machines is fixed by bolts, which affects the practicality of the device. Replacing the grinding mechanism takes a lot of time and is not conducive to the later cleaning and maintenance of the device, resulting in low maintenance efficiency of the gear hobbing grinding mechanism. Therefore, in order to solve the above problems, this utility model proposes a gear hobbing machine for processing motor gear shafts. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a gear hobbing machine for machining motor gear shafts. By adjusting the engagement between the limit block and the groove using a servo motor, the gear hobbing mechanism can be quickly disassembled and assembled to adapt to different usage requirements. This avoids wasting a lot of time during disassembly and assembly, greatly improving the practicality of the device and facilitating subsequent cleaning and maintenance, thus effectively improving the maintenance efficiency of the gear hobbing mechanism.

[0005] This utility model provides the following technical solution: a gear hobbing machine for machining motor gear shafts, comprising two symmetrical connecting seats, with rotating blocks movably sleeved on corresponding surfaces of the two connecting seats. A servo motor is fixedly installed in the inner cavity of each rotating block. A gear one is fixedly installed on the output shaft of the servo motor. A gear two is meshed with the outer edge of the gear one. A threaded rod is fixedly sleeved in the middle of the gear two. The threaded rod is movably sleeved in the inner cavity of the rotating block. A movable plate is threadedly sleeved on the threaded rod. A sliding rod is fixedly sleeved in the inner cavity of the rotating block and located below the servo motor. The rod is movably connected to the movable plate. A limit block is fixedly installed on the side of the movable plate away from the servo motor. The limit block is movably connected to the inner cavity of the rotating block. A rotating roller is provided between the two rotating blocks. Grinding teeth are fixedly sleeved on the rotating roller. Grooves are opened at both ends of the rotating roller. The grooves are engaged with the limit blocks. The engagement between the limit blocks and the grooves is adjusted by the servo motor to realize the quick assembly and disassembly of the gear hobbing mechanism, adapting to different usage needs. This greatly improves the practicality of the device, facilitates the later cleaning and maintenance of the device, and effectively improves the maintenance efficiency of the gear hobbing mechanism.

[0006] Preferably, a base plate is fixedly installed at the bottom of the connecting seat on the left side, a drive motor is fixedly installed on the upper part of the base plate, a differential is fixedly installed on the left side of the drive motor, the output shaft of the differential is movably connected to the connecting seat, and the output shaft of the differential is fixedly connected to the rotating block through a coupling. The moving mechanism moves the gear shaft component to the front of the grinding teeth, the drive motor is turned on, and the rotating block is driven to rotate by the connection of the differential. The rotating block drives the rotating roller to rotate, so that the grinding teeth on the rotating roller grind the tooth grooves on the gear shaft component.

[0007] Preferably, the bottom of the base plate is movably connected to a base via a shaft, and a hydraulic rod is fixedly installed on the upper part of the base. There are two hydraulic rods, which are symmetrically distributed front and back. The telescopic ends of the hydraulic rods are movably connected to the base plate 2 via a shaft. The base plate 2 is fixedly connected to the right connecting seat. The height of the right base plate 2 can be adjusted by the hydraulic rods, thereby changing the grinding angle of the grinding teeth and improving the flexibility of the gear hobbing structure.

[0008] Preferably, an electric actuator is fixedly installed at the rear of the connecting seat, and a movable plate two is fixedly installed between the telescopic ends of the two electric actuators. A brush is fixedly installed on the side of the movable plate two facing the grinding teeth. A collection pool is provided on the base and directly below the grinding teeth. A filter screen is snapped onto the collection pool. During the grinding process, the electric actuator is turned on to move the movable plate two, so that the brush approaches the surface of the grinding teeth to clean the metal debris remaining on it. The metal debris falls onto the filter screen, which is convenient for maintenance personnel to collect and clean in a unified manner later.

[0009] Preferably, a liquid storage box is fixedly installed at the rear of the base. The liquid storage box is connected to the collection tank via a condenser. A pump is fixedly installed on the upper part of the liquid storage box, and a delivery pipe is fixedly installed on the upper part of the pump. A sprayer is fixedly installed at the front end of the delivery pipe. The sprayer is located directly above the grinding teeth. Five nozzles are evenly fixedly installed at the bottom of the sprayer. During the grinding process, the pump is turned on to pump out the coolant from the liquid storage box. The coolant is sprayed onto the grinding teeth through the nozzles to cool them down. The coolant then passes through a filter screen into the collection tank, and is further cooled by the condenser located between the collection tank and the liquid storage box before returning to the liquid storage box for recycling.

[0010] Compared with the prior art, the advantages of this utility model are as follows: 1. A servo motor drives gear one to rotate, and the meshing of gear one and gear two drives the threaded rod to rotate. During the rotation of the threaded rod, the moving plate one moves, causing the limit block to move into the inner cavity of the rotating block, breaking the engagement between the limit block and the groove, thus facilitating the removal of the grinding teeth. The above operation is reversed during installation. Compared with the traditional method of fixing with bolts, this method facilitates the quick replacement of the gear hobbing mechanism to adapt to different usage needs in actual situations, greatly improving the practicality of the device, facilitating the later cleaning and maintenance of the device, and effectively improving the maintenance efficiency of the gear hobbing structure.

[0011] 2. The height of the right base plate is adjusted by hydraulic rods to change the grinding angle of the grinding teeth, thereby improving the flexibility of the gear hobbing structure. During grinding, the pump is turned on so that coolant is sprayed onto the grinding teeth through the nozzles, preventing the gear hobbing mechanism from deforming due to heat during grinding and ensuring the normal operation of the gear hobbing. The coolant passes down through the filter screen into the collection tank, and then passes through the condenser set between the collection tank and the storage box for cooling before returning to the storage box for recycling. During grinding, the electric actuator is turned on to move the second moving plate, so that the brushes approach the surface of the grinding teeth to clean the residual metal debris. The metal debris falls onto the filter screen, making it easy for maintenance personnel to collect and clean it, thus improving the material recovery efficiency of the device.

A sliding rod 8 is fixedly sleeved in the inner cavity of the rotating block 2 and below the servo motor 3. The sliding rod 8 is movably sleeved with the movable plate 7. A limiting block 9 is fixedly installed on the side of the movable plate 7 away from the servo motor 3. The limiting block 9 is movably sleeved with the inner cavity of the rotating block 2. A rotating roller 10 is arranged between the two rotating blocks 2. The device is fitted with a fixed grinding tooth 11. The rotating roller 10 has grooves 12 at both ends. The grooves 12 engage with the limiting block 9. When replacing the grinding tooth 11, the servo motor 3 drives the gear 4 to rotate. The meshing of the gear 4 and the gear 5 drives the threaded rod 6 to rotate. During the rotation of the threaded rod 6, the moving plate 7 moves, causing the limiting block 9 to move into the inner cavity of the rotating block 2. This disconnects the engagement between the limiting block 9 and the groove 12, making it easy to remove the grinding tooth 11. The installation is done by reversing the above steps. Compared with the traditional method of fixing with bolts, this method facilitates the quick replacement of the gear hobbing mechanism to adapt to different usage needs in actual situations. This greatly improves the practicality of the device, facilitates the later cleaning and maintenance of the device, and effectively improves the maintenance efficiency of the gear hobbing structure. A base plate 13 is fixedly installed at the bottom of the left connecting seat 1. A drive motor 14 is fixedly installed on the upper part of the base plate 13. A differential 15 is fixedly installed on the left side of the drive motor 14. The output shaft of the differential 15 is movably connected to the connecting seat 1. The output shaft of the differential 15 is fixedly connected to the rotating block 2 through a coupling. A base 16 is movably connected to the bottom of the base plate 13 through a shaft. Two hydraulic rods 17 are fixedly installed on the upper part of the base 16. The hydraulic rods 17 are symmetrically distributed front and back. The telescopic ends of the hydraulic rods 17 are movably connected to a base plate 18 through a shaft. The base plate 18 is connected to the right... The side connecting seat 1 is fixedly connected, and the height of the right base plate 18 can be adjusted by the hydraulic rod 17, thereby changing the grinding angle of the grinding teeth 11 and improving the flexibility of the gear hobbing structure. An electric push rod 19 is fixedly installed at the rear of the connecting seat 1. A movable plate 20 is fixedly installed between the telescopic ends of the two electric push rods 19. A brush 21 is fixedly installed on the side of the movable plate 20 facing the grinding teeth 11. A collection pool 22 is opened on the base 16 and located directly below the grinding teeth 11. A filter screen 23 is snapped onto the collection pool 22. A liquid storage box 24 is fixedly installed at the rear of the base 16. 4 is connected to the collection tank 22 via a condenser. A pump 25 is fixedly installed on the upper part of the liquid storage box 24, and a delivery pipe 26 is fixedly installed on the upper part of the pump 25. A sprayer 27 is fixedly installed at the front end of the delivery pipe 26. The sprayer 27 is located directly above the grinding teeth 11. Five nozzles 28 are evenly fixedly installed at the bottom of the sprayer 27. During the grinding process, the pump 25 is turned on to pump out the coolant from the liquid storage box 24. The coolant is sprayed onto the grinding teeth 11 through the nozzles 28 to cool the grinding teeth 11 during grinding and prevent the gear hobbing mechanism from being damaged during grinding. The device undergoes significant deformation due to heat, ensuring the normal operation of the gear hobbing process. The coolant flows downward through the filter screen 23 into the collection tank 22, and then passes through the condenser located between the collection tank 22 and the storage box 24 for cooling before re-entering the storage box 24 for recycling. During the grinding process, the electric push rod 19 is activated to move the moving plate 20, allowing the brush 21 to approach the surface of the grinding teeth 11 to clean the residual metal debris. The metal debris falls onto the filter screen 23, making it easy for maintenance personnel to collect and clean it later, thus improving the material recovery efficiency of the device.

[0016] Working principle: The moving mechanism moves the gear shaft component to the front of the grinding teeth 11. The drive motor 14 is turned on and the rotating block 2 is driven to rotate through the differential 15. The rotating block 2 drives the rotating roller 10 to rotate, so that the grinding teeth 11 on the rotating roller 10 grind the tooth grooves on the gear shaft component. The moving mechanism drives the gear shaft component to move to achieve continuous gear hobbing. The height of the right base plate 18 can be adjusted by the hydraulic rod 17 to change the grinding angle of the grinding teeth 11 to meet different grinding requirements. During the grinding process, the pump 25 is turned on to pump out the coolant in the storage box 24. The coolant is sprayed onto the grinding teeth 11 through the nozzle 28 to cool the grinding teeth 11 during grinding. The coolant passes down through the filter screen 23 into the collection tank 22, and then through the collection tank... The condenser between 22 and the liquid storage box 24 is used for cooling, and the liquid is recycled back into the liquid storage box 24. During the grinding process, the electric push rod 19 is turned on to move the moving plate 20, so that the brush 21 approaches the surface of the grinding teeth 11 to clean the metal debris remaining on it. The metal debris falls onto the filter screen 23, which is convenient for the maintenance personnel to collect and clean in a unified manner. When replacing the grinding teeth 11, the servo motor 3 drives the gear 4 to rotate. The meshing of gear 4 and gear 5 drives the threaded rod 6 to rotate. During the rotation of the threaded rod 6, the moving plate 7 moves, so that the limit block 9 moves into the inner cavity of the rotating block 2, and the engagement between the limit block 9 and the groove 12 is broken, so that the grinding teeth 11 can be removed. The above operation is reversed during installation.
