This design includes a fixed-end gear hobbing power mechanism, a sliding-end gear hobbing power mechanism, a long-shaft clamping mechanism, a cooling system, and a chip removal system. Although this device achieves partial chip cleaning through the chip removal system, its cleaning module only targets chip processing and does not address oil stain removal. Furthermore, its automation level is low, requiring manual intervention for cleaning. In addition, the chip removal system in this design has a complex structure and high maintenance costs, making it difficult to meet the modern industrial demand for efficient and low-cost cleaning.

The multi-axis robotic arm 9 is driven by a servo motor to achieve multi-degree-of-freedom movement, ensuring that the robotic arm can move accurately between different devices. The mounting plate is fixed to the end of the multi-axis robotic arm 9. The grippers 10 are made of flexible material and have anti-slip textures on their inner side to improve clamping stability. The nozzles of the cleaning air valves 11 are connected by universal joints, allowing the spray angle to be adjusted as needed. The base of the multi-axis robotic arm 9 is fixed to the equipment base with bolts, and its base is equipped with a shock-absorbing device to reduce vibration during operation of the robotic arm.

[0019] The cleaning equipment 5 includes a cleaning bracket, a cleaning hood 12 with a side opening mounted on the cleaning bracket, a gear positioning fixture 13 placed inside the cleaning hood 12, and a cleaning head 14 placed on the inner wall of the cleaning hood 12 and facing the gear positioning fixture 13. A door stop 15 is provided at the side opening of the cleaning hood 12, and the door stop 15 is driven by a cylinder to move up and down. The cleaning head 14 is connected to an external water circulation system through a pipe. The gear positioning fixture 13 includes a rotating motor, a rotating main shaft 16 driven by the rotating motor, and several sets of positioning components 17 mounted on the rotating main shaft 16. Each positioning component 17 includes a bottom pad and an inner ring retainer pin mounted on the bottom pad. Three sets of positioning components 17 are provided and are evenly distributed on the inner ring of the gear. A cleaning hood 12 is mounted on a cleaning support and has a side opening with a door stop 15 at the side opening. The door stop 15 is driven by a cylinder to move up and down, thereby controlling the opening and closing of the cleaning hood 12. A gear positioning fixture 13 is placed inside the cleaning hood 12 and includes a rotating motor, a rotating spindle 16, and several sets of positioning components 17. The rotating motor is connected to the rotating spindle 16 via a coupling, and the rotating spindle 16 is mounted inside the cleaning hood 12 via bearings.

The inner ring pin is fixed to the bottom pad by threads and has a small diameter, contacting only the inner ring of the gear to achieve three-point positioning. Cleaning heads 14 are located on the inner wall of the cleaning hood 12, distributed opposite the gear positioning fixture 13, and are connected to an external water circulation system via pipes. The water circulation system provides high-pressure water flow to the cleaning heads 14. The inner wall of the cleaning hood 12 is also provided with a guide channel, which is spirally distributed along the inner wall of the cleaning hood 12 to guide the cleaning fluid to the drain outlet at the bottom of the cleaning hood 12. The rotating main shaft 16 is provided with a through drainage channel. One end of the drainage channel is connected to the drain outlet at the bottom of the cleaning hood 12, and the other end is connected to an external wastewater treatment system through a hose.

[0020] The specific structure of the oil slinger can be referenced from the automatic gear oil removal device with existing patent document publication number CN214052918U.

[0021] In this implementation, the unprocessed gears are first placed in the unprocessed gear placement area of ​​the gear loading module 1. The circulating conveyor belt, driven by a motor, starts operating and transports the gear fixture 8 and its gears from the placement area to the exit position.

[0022] The multi-axis robotic arm 9 of the robotic arm 6 is precisely moved to the exit point by a servo motor. A clamping cylinder drives the gripper 10 to pick up the gear, and the anti-slip texture on the inner side of the gripper 10 ensures clamping stability. The robotic arm 6 transports the gear to the gear hobbing machine 2. The gear hobbing fixture is fixed to the gear by a hydraulic locking device to ensure its stability during processing. The gear hobbing cutter, driven by a gear hobbing motor, performs gear hobbing. The cutting edge is made of high-speed steel, which can efficiently complete the gear tooth profile machining. After processing, the robotic arm 6 picks up the gear again and transports it to the oil slinger 3. When the gear is placed in the oil slinger 3, the rotating tray rotates at high speed driven by the oil slinger motor, using centrifugal force to throw off excess oil from the gear surface. The oil flows through the drainage holes on the surface of the rotating tray into the oil collection tank at the bottom of the oil slinger chamber and is then transported to an external oil recovery system through pipelines.

[0023] The robotic arm 6 then picks up the gear again and transports it to the corner trimming machine 4. Driven by a corner trimming motor, the corner trimming cutter trims the edges of the gear. The cutting edge is made of carbide to ensure precision and efficiency in the trimming process. After trimming, the robotic arm 6 transports the gear to the cleaning equipment 5. In the cleaning equipment 5, the door stop 15 moves upward via a cylinder, opening the side opening of the cleaning hood 12. The robotic arm 6 places the gear on the gear positioning fixture 13. The positioning assembly 17 achieves three-point positioning via a bottom pad and an inner ring retaining pin, avoiding the problem of traditional positioning pins obstructing the inner ring of the gear. After the door stop 15 closes, the cleaning head 14 thoroughly cleans the gear using high-pressure water supplied by an external water circulation system. Simultaneously, a rotating motor drives the rotating spindle 16 to rotate via a coupling, causing the gear to rotate and ensuring that the cleaning head 14 covers the entire surface of the gear. The cleaning fluid flows through the guide channel on the inner wall of the cleaning hood 12 to the bottom drain outlet and is discharged to the external wastewater treatment system through the drainage channel inside the rotating spindle 16. After cleaning, the robotic arm 6 picks up the gear and transports it to the processed gear recycling area of ​​the gear loading module 1, completing the entire processing flow. Throughout the process, the cleaning air valve 11 provides high-pressure gas through an external air source, and the nozzle adjusts its angle through a universal joint to blow and clean the gear surface or the machined area of ​​the equipment, ensuring that there are no residual chips or oil stains in the processing area.

[0024] The advantages of this utility model are that, by setting up a robotic arm and a cleaning air valve, the gears are automatically transported and cleaned between different devices, reducing manual intervention and improving production efficiency; the nozzle of the cleaning air valve can adjust the spray angle as needed to ensure the cleaning effect on the gear surface and the processing position of the equipment. By designing a gear positioning fixture in the cleaning equipment and using a three-point positioning method to fix the gear, the problem of the traditional positioning pin blocking the inner ring of the gear is avoided, thus achieving comprehensive cleaning of the inner and outer surfaces of the gear; at the same time, by driving the gear to rotate through a rotating motor, combined with the high-pressure water flow from the cleaning head, the cleaning effect is further improved. By setting up an oil-spinning machine and an edge-trimming machine, excess oil after gear processing is removed and the edges of the gears are trimmed, ensuring the surface quality of the gears and the smooth progress of subsequent processing.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
