Description

Technical Field

[0001] This invention belongs to the field of gear shaping technology, and in particular relates to a gear processing device. Background Technology

[0002] Gears are core components of various mechanical transmission equipment and are widely used in aerospace, automotive, engineering machinery, precision machine tools and other fields. Machining accuracy and efficiency directly determine the transmission performance and service life of the whole machine. Gear shaping is a key process for forming complex gears, especially suitable for internal gear rings and double gears. High-speed gear shaping relies on high-frequency reciprocating cutting and has now become the mainstream solution for mass production of precision gears. At present, the industry has developed an automated loading and unloading solution with AGV as the carrier, combined with 3D vision recognition and magnetic gripping, which can complete the automatic delivery of gear blanks, identification of model front and back and posture correction, ensuring that the workpiece is accurately delivered to the workstation.

[0003] The existing high-speed gear shaping process and its supporting cooling system for internal gear rings have the following problems: During the high-speed gear shaping process, the gear shaping cutter collides and rubs against the internal gear ring tooth groove at high speed. The coolant in the cutting area is easily atomized into a large number of micron-sized droplets due to the high-speed impact and tearing. The droplets are easily lost with the equipment exhaust, resulting in rapid coolant loss. Frequent coolant replenishment is required during production, which not only increases the cost of consumables and labor maintenance, but also affects the continuity of production and increases the overall processing cost. In addition, the machining of internal gear rings is a closed-cavity machining process. The machining cavity space is small and the ventilation is poor. The mist generated by high-speed cutting cannot be dissipated in time, and the heat inside the cavity is also difficult to dissipate. High temperature will cause cutting thermal deformation of the internal gear ring workpiece, resulting in out-of-tolerance tooth profile and pitch accuracy, and reducing the product qualification rate.

[0004] To address this problem, a gear processing device is proposed. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing a gear processing apparatus.

The upper side wall of the collection box has a collection port for collecting waste. A collection component, disposed inside the suction component, is used to collect atomized coolant droplets; A separation component, disposed inside the collection box and located below the extraction component, is used to separate iron filings and coolant.

[0007] In the aforementioned gear processing device, the air extraction assembly includes an air extraction ring fixedly connected inside the collection box. The air extraction ring has a hollow structure, and an annular opening is formed on the inner wall of the air extraction ring. An annular filter screen is fixedly connected to the inner wall of the annular opening. A storage box is provided on the left side of the collection box. An installation hopper is fixedly connected to the inner wall of the storage box via a bracket. The collection assembly is disposed in the installation hopper. The collection assembly and the air extraction ring are fixedly connected to the same air extraction pipe. A drain pipe is fixedly connected to the lower end of the installation hopper. A control valve is provided in the drain pipe. An air extraction pump is fixedly connected to the left side wall of the storage box. The air extraction end of the air extraction pump is connected to the drain pipe.

[0008] In the aforementioned gear processing device, the collecting assembly includes a mounting ring fixedly connected within the mounting hopper. A collecting cylinder is fixedly connected to the inner wall of the mounting ring. A drain port is provided on the lower side wall of the collecting cylinder. A perforated tube is fixedly connected to the lower inner wall of the collecting cylinder. Oil-absorbing cotton is filled between the perforated tube and the collecting cylinder. A mounting cover is connected to the upper side wall of the collecting cylinder via a flange. Two small electric push rods are fixedly connected to the upper side wall of the mounting cover. The moving ends of the two small electric push rods pass through the mounting cover and are fixedly connected to the same pressure ring. The pressure ring is located between the collecting cylinder and the perforated tube. Multiple short pipes are connected to the side wall of the collecting cylinder. The ends of the multiple short pipes away from the collecting cylinder are fixedly connected to the same ring pipe. The ring pipe is connected to a suction pipe.

[0009] In the aforementioned gear processing device, the separation component includes a crushing mechanism fixedly connected inside a collection box. The crushing mechanism is located directly below the suction ring. A vibrating screen located below the crushing mechanism is fixedly connected to the inner wall of the collection box. The vibrating screen is connected to an external power source. A discharge port is provided on the front side wall of the collection box. The vibrating screen is inclined and the discharge end of the vibrating screen is aligned with the discharge port.

[0010] In the aforementioned gear processing device, the upper end of the storage box has an open structure, a cover plate is hinged to the upper side wall of the storage box, and a handle is fixedly connected to the upper side wall of the cover plate.

[0011] In the aforementioned gear processing device, guide plates are fixedly connected to the inner walls of both the left and right sides of the collection box, and both guide plates are located between the crushing mechanism and the suction ring.

[0012] In the aforementioned gear processing device, a filter screen is fixedly connected to the inner wall of the storage box, a delivery pump is fixedly connected to the side wall of the storage box, the inlet end of the delivery pump is connected to the lower part of the collection box, the outlet end of the delivery pump passes through the storage box and is located below the filter screen, and the lower end of the drain pipe passes through the filter screen.

[0013] In the aforementioned gear processing device, a collection cover is fixedly connected to the front side wall of the collection box, and the collection cover and the discharge port are aligned.

[0014] Compared with existing technologies, the advantages of a gear processing device are: In this invention, when the main unit drives the gear cutter to perform high-speed operation on the internal gear ring through the moving parts, the air pump will extract the gas inside the collection component and the air extraction ring. The coolant droplets generated after being impacted by the high-speed gear cutter, as well as the heat generated during the processing, are transported to the collection cylinder through the air extraction ring and the air extraction pipe under the action of the airflow, which can avoid the impact of high temperature on the internal gear ring. At the same time, the oil-absorbing cotton in the collection cylinder collects the coolant droplets in the airflow. Subsequently, the collected coolant can be squeezed out and recycled by squeezing the oil-absorbing cotton, thereby reducing the waste of coolant.

[0015] In this invention, during the cutting process of the gear cutter on the internal gear ring, the cut iron chips will first fall into the crushing mechanism. The crushing mechanism will crush some of the long and clumped iron chips, so that the coolant wrapped inside the long and clumped iron chips will be released. After being crushed, the iron chips fall onto the vibrating screen along with the released coolant for separation, thereby further improving the coolant recovery efficiency.

[0016] In this invention, when the air pump extracts gas from the inside of the collection cylinder and the air extraction ring, the air extraction channel is set inside the porous pipe. The mist droplets collected by negative pressure will be evenly distributed around the oil-absorbing cotton along with the air extraction pipe, the ring pipe and multiple short pipes, so that the oil-absorbing cotton is fully utilized and the utilization rate of the oil-absorbing cotton is guaranteed.

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] like Figures 1-4 As shown, a gear processing device includes a main unit 1, a moving part 2 on the front side of the main unit 1, and a gear shaping cutter 3 connected to the moving end of the moving part 2. It also includes: a collection box 4, located below the gear shaping cutter 3; an automatic clamp 5 connected to the upper side wall of the collection box 4 via a power component; a magnetic suction robotic arm assembly 29 connected to the front side wall of the collection box 4; and an air extraction assembly 6, located inside the collection box 4, directly below the automatic clamp 5. The upper side wall of the collection box 4 has a collection port for collecting waste materials. The air extraction assembly 6 includes an air extraction ring 61 fixedly connected inside the collection box 4. The air extraction ring 61 has a hollow structure and is used for air extraction. The inner wall of ring 61 has an annular opening, and an annular filter screen 62 is fixedly connected to the inner wall of the annular opening. A storage box 7 is provided on the left side of the collection box 4. The upper end of the storage box 7 is an open structure. A cover plate 24 is hinged to the upper side wall of the storage box 7. A handle is fixedly connected to the upper side wall of the cover plate 24. An installation hopper 8 is fixedly connected to the inner wall of the storage box 7 through a bracket. The collection component 13 is set in the installation hopper 8. The collection component 13 and the suction ring 61 are fixedly connected to the same suction pipe 9. A drain pipe 10 is fixedly connected to the lower end of the installation hopper 8. A control valve 11 is provided in the drain pipe 10. A suction pump 12 is fixedly connected to the left side wall of the storage box 7. The suction end of the suction pump 12 is connected to the drain pipe 10.

[0021] In actual use, in this embodiment, the gas inside the drain pipe 10 (with the control valve 11 inside the drain pipe 10 in a closed state, so that the lower port of the drain pipe 10 is closed) and the collection cylinder 132 is extracted by the vacuum pump 12. Under negative pressure, the external gas will pass through the internal gear ring and the automatic clamp 5 and enter the vacuum ring 61. The small amount of iron filings carried in the gas will be blocked by the annular filter screen 62. The heat generated during the internal gear ring processing and the droplets from the high-speed impact of the gear cutter 3 will be transported to the collection assembly 13 for storage through the vacuum pipe 9.

[0022] like Figures 4-7 As shown, in this embodiment, the collecting component 13 is disposed inside the suction component 6 and is used to collect atomized coolant droplets. The collecting component 13 includes a mounting ring 131 fixedly connected to the mounting hopper 8. A collecting cylinder 132 is fixedly connected to the inner wall of the mounting ring 131. A drain port 14 is provided on the lower side wall of the collecting cylinder 132. A porous tube 15 is fixedly connected to the lower inner wall of the collecting cylinder 132. Oil-absorbing cotton 16 is filled between the porous tube 15 and the collecting cylinder 132. The upper side wall of 2 is connected to a mounting cover 17 via a flange. Two small electric push rods 18 are fixedly connected to the upper side wall of the mounting cover 17. The moving ends of the two small electric push rods 18 pass through the mounting cover 17 and are fixedly connected to the same pressure ring 19. The pressure ring 19 is located between the collecting cylinder 132 and the porous tube 15. The side wall of the collecting cylinder 132 is connected to multiple short tubes 20. The ends of the multiple short tubes 20 away from the collecting cylinder 132 are fixedly connected to the same ring tube 21. The ring tube 21 is connected to the suction pipe 9.

[0023] In actual use, in this embodiment, the droplets are transported to the ring pipe 21 through the suction pipe 9, and then the droplets are evenly distributed on the surface of the oil-absorbing cotton 16 through multiple short pipes 20. After the internal gear ring processing is completed, the operator controls the two small electric push rods 18 to work and opens the control valve 11. The small electric push rods 18 will drive the pressure ring 19 to move downward, and use the pressure ring 19 to squeeze the oil-absorbing cotton 16, so that the coolant absorbed by the oil-absorbing cotton 16 is squeezed out. The squeezed coolant will pass through the porous pipe 15 and fall to the bottom of the installation hopper 8 through the drain port 14, and then be discharged through the drain pipe 10 to the bottom of the filter screen 26 in the storage box 7.

[0024] like Figures 1-2As shown, in this embodiment, the separation component 22 is further disposed inside the collection box 4 and located below the suction component 6. It is used to separate iron filings and coolant. The separation component 22 includes a crushing mechanism 221 fixedly connected inside the collection box 4. Guide plates 25 are fixedly connected to the inner walls of both sides of the collection box 4. The two guide plates 25 are located between the crushing mechanism 221 and the suction ring 61. The crushing mechanism 221 is located directly below the suction ring 61. A vibrating screen 222 located below the crushing mechanism 221 is fixedly connected to the inner wall of the collection box 4. The vibrating screen 222 is connected to an external power source. A discharge port 23 is opened on the front side wall of the collection box 4. A collection cover 28 is fixedly connected to the front side wall of the collection box 4, and the collection cover 28 and the discharge port 23 are aligned. The vibrating screen 222 is inclined, and the discharge end of the vibrating screen 222 is aligned with the discharge port 23.

[0025] In actual use, the iron filings cut off by the internal gear ring in this embodiment will first fall into the crushing mechanism 221. The crushing mechanism 221 will crush some of the long and clumped iron filings, so that the coolant wrapped inside the long and clumped iron filings will be released. The crushed iron filings will fall onto the vibrating screen 222 for screening along with the released coolant. The coolant will pass through the vibrating screen 222 and fall into the collection box 4. The crushed iron filings will fall into the collection cover 28 through the discharge port 23.

[0026] like Figure 4 As shown, in this embodiment, a filter screen 26 is fixedly connected to the inner wall of the storage box 7, and a delivery pump 27 is fixedly connected to the side wall of the storage box 7. The inlet end of the delivery pump 27 is connected to the lower part of the collection box 4, the outlet end of the delivery pump 27 passes through the storage box 7 and is located below the filter screen 26, and the lower end of the drain pipe 10 passes through the filter screen 26.

[0027] In actual use, in this embodiment, the delivery pump 27 delivers the filtered coolant in the collection tank 4 to the area below the filter screen 26 in the storage tank 7. When the processing device continues to work, the matching cooling system will draw away the filtered coolant from above the filter screen 26 for recycling.

[0028] The operating principle of this invention is explained as follows: The AGV trolley moves the internal gear ring to be processed to a suitable position in front of the magnetic suction robotic arm assembly 29. The magnetic suction robotic arm assembly 29 places the internal gear ring to be processed into the automatic clamp 5. The automatic clamp 5 then installs the internal gear ring above the collection box 4. Subsequently, the main unit 1 drives the gear shaping cutter 3 to work through the moving part 2, and uses the gear shaping cutter 3 to process the internal gear ring. At the same time, the matching cooling system sprays coolant onto the processing area of ​​the internal gear ring. Excess coolant will pass through the surface of the collection box 4. The surface collection port and vibrating screen 222 fall into the collection box 4. At the same time, the air pump 12 is in working condition, extracting the gas inside the collection cylinder 132 and the air extraction ring 61. The coolant that is impacted into droplets and the heat generated during the operation will be transported to the oil-absorbing cotton 16 in the collection cylinder 132 under the action of airflow. The oil-absorbing cotton 16 absorbs the droplets, and the heat will be extracted by the air pump 12. Finally, the small electric push rod 18 drives the pressure ring 19 to squeeze the oil-absorbing cotton 16, so that the coolant absorbed by the oil-absorbing cotton 16 is squeezed out and collected.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
