Description

Technical Field

[0001] This invention belongs to the field of gear processing technology, specifically a gear forming machine. Background Technology

[0002] Gears are important transmission components in mechanical devices and are widely used in various mechanical transmission mechanisms. In the milling process of gears, the workpiece is first machined into a cylinder with a hole in the middle through rough turning, finish turning, boring and other processes. Then, the workpiece is positioned by the end face and inner hole of the workpiece. Finally, the multiple teeth of the gear are cut and shaped by the cutting process. At present, gear processing methods include gear hobbing and gear shaping. When machining gears by gear hobbing, the gear blank needs to be fixed first. Then, the gear blank is rotated and moved closer to the rotating cutting tool so that the gear blank is machined by the cutting tool.

[0003] In the current process of machining gear blanks into gears by cutting tools, the gear blanks need to be firmly fixed. Currently, when fixing the gear blanks, the gear blanks are placed on the shaft, and then a pressing structure is attached to the shaft. The pressing structure is tightened by meshing with the shaft through a nut, thereby fixing the gear blanks. The whole process is quite cumbersome. When the fixing is removed after the gear hobbing is completed, the meshing between the nut and the shaft must be released. The working efficiency of the entire process of gear hobbing is low, which is not conducive to the mass production of gears.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 8 As shown, a gear forming machine according to an embodiment of the present invention includes a worktable 1. A slide groove is provided at the top of the worktable 1. A receiving plate 11 is slidably connected inside the slide groove. A buffer member 12 is fixedly connected to the end of the receiving plate 11. A first hydraulic cylinder 13 is provided on the side of the buffer member 12 away from the receiving plate 11. The output end of the first hydraulic cylinder 13 is connected to the buffer member 12. A first motor 4 is fixedly connected to the top of the receiving plate 11. A rotating disk 41 is fixedly connected to the output end of the first motor 4. Multiple isolation covers 42 are fixedly connected to the top of the rotating disk 41 in a ring shape. A second motor is installed inside the isolation cover 42. The output end of the second motor extends through to the top of the isolation cover 42 and is fixedly connected to a rotating cylinder 43. Multiple rectangular holes are opened on the side of the rotating cylinder 43. Brake blocks 432 are inserted into the rectangular holes. One end of the brake block 432 located inside the rotating cylinder 43 is set as an inclined surface. The rotating cylinder 43... An extrusion plate 431 is provided inside and above the inclined surface. Multiple connecting springs 433 are fixed to the side of the extrusion plate 431 and the inner wall of the rotating cylinder 43. A support ring 421 is sleeved on the side of the rotating cylinder 43. A rotating column 44 is fixed to the center of the top of the rotating plate 41. Multiple auxiliary frames 45 are fixed to the top of the rotating column 44 in a ring shape. A second hydraulic cylinder 46 is installed at the top of the auxiliary frame 45. An extrusion block 47 located directly above the extrusion plate 431 is fixed to the output end of the second hydraulic cylinder 46. A tool assembly 14 is fixedly connected to the top of the workbench 1 and to one side of the chute. A discharge conveyor 2 and a loading conveyor 3 are respectively installed on the sides of the workbench 1. When performing gear hobbing, the gear blank is fitted onto the shaft, and then an extrusion structure is fitted onto the shaft. The extrusion structure is tightened by meshing with the shaft through a nut, thereby fixing the gear blank. The whole process is quite cumbersome. After the gear hobbing is completed, the meshing between the nut and the shaft must be released to remove the fixation. The working efficiency of the entire process is low, which is not conducive to the mass production of gears. To solve the above problems, the embodiment of the present invention sets up a rotating cylinder 43 and other structures. The specific usage process is as follows: When in use, the gear blank is fitted onto the rotating cylinder 43 and supported by the support ring 421. Then, the second hydraulic cylinder 46 is started. The output end of the second hydraulic cylinder 46 drives the extrusion block 47 to move downward. The extrusion block 47 extrudes to the top of the extrusion disc 431. The extrusion disc 431 is extruded downward and extrudes the inclined surface of the brake block 432 below. The brake block 432 is extruded to move outward of the rectangular hole opened on the side of the rotating cylinder 43, and then extrudes to the inner wall of the gear blank, generating friction braking with the inner wall of the gear blank to fix the position of the gear blank. The downward compressive force on the gear blank is transmitted downward through the support ring 421. Multiple struts are fixed between the support ring 421 and the isolation cover 42, so that the downward compressive force on the gear blank during gear hobbing is distributed to the isolation cover 42 through the struts, protecting the second motor inside the isolation cover 42 and preventing excessive downward compressive force on the output end of the second motor. During gear hobbing, the first hydraulic cylinder 13 is activated, and the output end of the first hydraulic cylinder 13 drives the buffer 12 to move. The buffer 12 drives the receiving plate 11 to move within the slide groove, and the receiving plate 11 drives the first motor to move towards the tool assembly 1. 4. Movement: The first motor 4 drives the rotating disk 41 at the output end to move, the rotating disk 41 drives the rotating cylinder 43 at the top to move, and the rotating cylinder 43 drives the gear blank after sleeve to move synchronously. While the gear blank to be hobbed is moving, the second motor drives the gear blank sleeved on the rotating cylinder 43 to rotate synchronously. When the gear blank contacts the hobbing cutter of the tool assembly 14, part of the gear blank is cut off by the rotating hobbing cutter. When the gear blank stops moving, the gear blank has teeth cut out, thus completing the gear manufacturing. Then, the manufactured gear is controlled to move away from the tool assembly 14, and then the extrusion block 47 is controlled to reset, connecting the spring. Under the action of spring 433, the pressing disc 431 is driven to reset and no longer presses the inclined surface of the brake block 432. The connection point between the connecting spring 433 and the pressing disc 431 is located near the top of the pressing disc 431, allowing the connecting spring 433 to bend fully when the pressing disc 431 moves downwards, without being obstructed by the top of the brake block 432, ensuring sufficient space for the pressing disc 431 to move. Furthermore, a magnetic block (not shown in the accompanying drawings) is provided at the bottom of the pressing disc 431, and the brake block 432 is made of magnetic metal. Therefore, when the pressing disc 431 resets... The brake block 432 is magnetically attracted and reset, and then the prepared gear is taken out and transported by the unloading conveyor 2. Then the first motor 4 is started. When the first motor 4 starts, it drives the rotating disk 41 to rotate 90 degrees, so that the gear blank on the other rotating cylinder 43 rotates to the working position. Then the above operation is repeated, which can effectively improve the gear processing efficiency. The operator does not need to frequently install the gear blank. After the processing of one gear blank is completed, the gear blanks in other positions can be processed continuously. After the processing of other gear blanks is completed, the unloading and loading can be carried out at one time, which is conducive to improving the processing efficiency. It should be noted that the top end of the support ring 421 is at the same height as the bottom end of the brake block 432, so the brake block 432 will not interfere with the support ring 421 when it moves; the tool assembly 14 includes a hobbing cutter and a motor for driving the hobbing cutter, as well as a support frame; coolant needs to be sprayed onto the gear blank synchronously during hobbing, and the second motor can be isolated from the coolant by setting the isolation cover 42 to protect the second motor.

[0023] like Figures 4 to 5As shown, a reinforcing ring 411 is provided at the bottom of the rotating disk 41. Multiple support rods 412 are fixed between the bottom of the reinforcing ring 411 and the receiving plate 11. A rotating ring 413 is rotatably connected to the top of the reinforcing ring 411, and the bottom of the reinforcing ring 411 is supported by the rotating ring 413. During the gear hobbing operation, the rotating disk 41 will be subjected to the downward force of the gear hobbing cutter of the tool assembly 14. The rotating disk 41 will transfer the compressive force to the reinforcing ring 411. The reinforcing ring 411 is supported on the receiving plate 11 by the support rods 412, which prevents the output end of the first motor 4 from being directly squeezed by the rotating disk 41 and protects the first motor 4.

[0024] like Figures 1 to 9As shown, the buffer 12 includes an air box 121, an air plate 122 is slidably connected inside the air box 121, the output end of the first hydraulic cylinder 13 extends into the air box 121 and is connected to the air plate 122, an air pump 123 is fixedly connected to the top of the air box 121, the output end of the air pump 123 extends into the air box 121, a pressure sensor is installed inside the air box 121, and the end of the air box 121 away from the first hydraulic cylinder 13 is fixedly connected to the end of the receiving plate 11. During the gear hobbing operation, the first hydraulic cylinder 13 controls the gear blank to move to contact the gear hobbing cutter of the tool assembly 14 and then stops. After that, during the process of the gear blank cutting the teeth, the gear blank needs to move further towards the gear hobbing cutter. The specific process of driving the gear blank to move is as follows. When the gear blank moves further, the air pump 123 is started. Since the position of the inflation plate 122 is fixed by the output end of the first hydraulic cylinder 13, when the air pump 123 inflates the inflation box 121, the air pressure inside the inflation box 121 will act on the end of the receiving plate 11. The resistance experienced by the receiving plate 11 is the squeezing force of the gear blank on the gear hobbing cutter. Therefore, the air pressure inside the inflation box 121 is the squeezing force of the gear blank on the gear hobbing cutter. The inflation box 121 is equipped with an air pressure sensor (not shown in the attached diagram of the manual). The air pressure sensor detects the real-time air pressure inside the inflation box 121 and transmits the signal to the external microcomputer. After receiving the signal, the microcomputer synchronously controls the output power of the air pump 123, so that the inflation box 121... 1. Maintaining a constant internal air pressure ensures a constant cutting resistance during gear blank feeding, which is beneficial for improving hobbing quality and provides greater stability compared to controlling the feed via the first hydraulic cylinder 13. It should be noted that maintaining a constant cutting resistance during gear blank cutting ensures cutting stability and prevents sudden changes in the relative position between the hob and the gear blank due to feed instability, which could lead to tooth chipping on the gear blank's surface. In actual cutting, debris generated during cutting may enter between the gear blank and the hob, causing fluctuations in the cutting resistance during gear blank feeding, which in turn can lead to tooth chipping. Therefore, the air box 121 and other structures in this embodiment are necessary to ensure a constant cutting resistance during gear blank feeding. Alternatively, if the air pump 123 is not started and the tooth blank is moved directly by the feed through the first hydraulic cylinder 13, the cutting resistance on the tooth blank will also increase when the debris enters between the tooth blank and the hobbing cutter, since the air pressure inside the air box 121 is the same as the cutting resistance on the tooth blank. This causes the air plate 122 inside the air box 121 to move inside the air box 121, further compressing the air inside the air box 121. This increases the gas pressure inside the air box 121, buffering the movement of the tooth blank, but tooth biting may still occur. When the air pump 123 is started, the air pressure sensor can control the air pressure inside the air box 121 to remain constant in real time. Specifically, the air pump 123 can either inflate or evacuate the air box 121.

[0025] like Figures 4 to 10 As shown, a support rod 51 is fixedly connected to the top of the rotating disk 41, and an inclined block 5 is fixedly connected to the top of the support rod 51. When the finished gear rotates, it passes through the inclined block 5 and is supported by the inclined part of the inclined block 5. The receiving end of the unloading conveyor 2 is located on one side of the inclined block 5. Multiple receiving inclined plates 410 are fixedly connected to the top of the rotating disk 41 and between the isolation covers 42. When unloading the finished gear, the rotating disk 41 is controlled to rotate counterclockwise by 90 degrees. During the rotation of the gear, the inclined part of the inclined block 5 will support the bottom of the gear and support the gear upward as the gear rotates. Finally, the gear passes over the rotating cylinder 43 and falls to the top of the receiving inclined plate 410. Then, it falls onto the conveyor belt of the unloading conveyor 2 through the receiving inclined plate 410. The finished gear is transferred by the unloading conveyor 2 to achieve automatic unloading. It should be noted that when the rotating cylinder 43 rotates, the inclined block 5 and the support rod 51 will not obstruct the rotating cylinder 43.

[0026] like Figures 10 to 12 As shown, a pair of baffles 21 are installed on both sides of the receiving end of the unloading conveyor 2. A notch is opened at the top of each baffle 21, and a crossbar 25 is inserted into the notch. A buffer ramp 26 is fixed to the end of the crossbar 25 closest to the center line of the unloading conveyor 2, and a first locking block 24 is fixed to the end of the crossbar 25 away from the buffer ramp 26. A support spring 23 is fixed to the bottom end of the first locking block 24, and a second locking block 22 is fixed to the bottom end of the support spring 23. The second locking block 22 is fixed to the side of the baffle 21. When the gear falls from the receiving ramp 410, the buffer ramp 26 will catch the gear. When the gear falls onto the top surface of the buffer ramp 26, it will press the buffer ramp 26 downwards, thus buffering the gear. The inclined plate 26 is restricted to a downward position within the notch by the crossbar 25, so that the buffer inclined plate 26 moves vertically. The first locking block 24 at the end of the crossbar 25 will squeeze the support spring 23, so that the support spring 23 is compressed and then extended, causing the buffer inclined plate 26 to move up and down, thereby preventing the gear from falling directly onto the conveyor belt of the unloading conveyor 2 and causing damage to the conveyor belt. Another pair of baffles 21 can restrict the position of the gear and prevent the gear from falling off the conveyor belt on the unloading conveyor 2. It should be noted that when the gear falls onto the buffer inclined plate 26, the buffer inclined plate 26 will move up and down, and then slide down onto the conveyor belt on the unloading conveyor 2 by the gravity of the gear itself.

[0027] like Figures 13 to 14As shown, a pair of partitions are fixed to both sides of the receiving inclined plate 410, and a buffer pad is fixed to the surface of the receiving inclined plate 410. A first rotating belt 27 is rotatably connected to the surface of the buffer inclined plate 26. By fixing a pair of partitions to both sides of the receiving inclined plate 410, the gear is prevented from falling off the side of the receiving inclined plate 410. The buffer pad is set to protect the gear and prevent it from being damaged by impact when it falls onto the receiving inclined plate 410. The setting of the first rotating belt 27 can prevent friction between the gear and the buffer inclined plate 26, further protecting the gear and preventing friction damage. Specifically, when the gear falls onto the surface of the first rotating belt 27, it will drive the first rotating belt 27 to rotate on the surface of the buffer inclined plate 26 under its own gravity. When the first rotating belt 27 rotates, it sends the gear onto the conveyor belt of the unloading conveyor 2.

[0028] like Figures 14 to 16 As shown, a support 31 is provided at the top of the feeding conveyor 3, and a third hydraulic cylinder 32 is installed at the top of the support 31. A fixed frame 33 is fixedly connected to the output end of the third hydraulic cylinder 32. A receiving cover 34 is fixedly connected to the end of the fixed frame 33 away from the third hydraulic cylinder 32. The receiving cover 34 is located at the unloading end of the feeding conveyor 3. An opening is provided on the side of the receiving cover 34 facing the feeding end of the feeding conveyor 3, through which the conveyed tooth blank can enter the interior of the receiving cover 34. A pair of air bladders 351 are fixedly connected to the inner wall of the receiving cover 34, and a pair of pump bodies 35 are fixedly connected to the outer side of the receiving cover 34. The output end of the pump body 35 is connected to the air bladders 351. After the rotating drum 43 rotates 90 degrees, the gears on the rotating drum 43 are removed. At this time, the rotating drum 43 is aligned with the unloading end of the feeding conveyor 3, and the unloading end of the feeding conveyor 3 is higher than the rotating drum 43. At the top of the rotating cylinder 43, during feeding, the feeding conveyor 3 transports the tooth blank to the inside of the receiving cover 34. Then, the pump body 35 starts and inflates the air bag 351. When the air bag 351 is inflated, it expands and squeezes and fixes the gear inside the receiving cover 34. Then, the third hydraulic cylinder 32 starts and the output end of the third hydraulic cylinder 32 drives the receiving cover 34 at the end of the fixing frame 33 to move. When the receiving cover 34 moves above the rotating cylinder 43, it stops. It is necessary to control the center line of the tooth blank to coincide with the center line of the rotating cylinder 43. Then, the pump body 35 evacuates the air bag 351, so that the air bag 351 no longer squeezes the tooth blank. The tooth blank falls downward and fits on the outside of the rotating cylinder 43, realizing automated feeding. It should be noted that during feeding, it is necessary to control the extrusion block 47 to move upward to avoid interfering with the feeding process.

[0029] like Figures 15 to 17As shown, a fourth hydraulic cylinder 36 is fixedly connected to the top of the receiving cover 34. The output end of the fourth hydraulic cylinder 36 extends into the inside of the receiving cover 34 and is fixedly connected to an insertion block 37. The diameter of the insertion block 37 is the same as the inner diameter of the conveyed tooth blank. When the tooth blank moves into the receiving cover 34, the fourth hydraulic cylinder 36 is activated first. The output end of the fourth hydraulic cylinder 36 drives the insertion block 37 to move downward. The diameter of the insertion block 37 is the same as the inner diameter of the tooth blank. The insertion block 37 can be inserted into the inner ring of the tooth blank, thereby restricting the position of the tooth blank and preventing the tooth blank from being squeezed and fixed by the airbag 351, which would cause the tooth blank to fall downward and not be accurately fitted onto the outside of the rotating cylinder 43. It should be noted that the tooth blank at the feeding end of the feeding conveyor 3 is fed by a robotic arm, which makes the position of the tooth blank on the feeding conveyor 3 accurate. When the tooth blank moves into the receiving cover 34, the inner ring can be accurately inserted by the insertion block 37.

[0030] like Figures 17 to 18 As shown, the annular circumferential surface of the insertion block 37 has multiple rectangular grooves 371, and the inner wall of the rectangular grooves 371 has insertion slots 372. An insertion rod 373 is inserted into the insertion slot 372, and a compression spring is fixed between the insertion rod 373 and the inner wall of the insertion slot 372. A transition ramp 374 is fixed to one end of the insertion rod 373 outside the insertion slot 372. For tooth blanks of different sizes, when the insertion block 37 moves downward, if the inner diameter of the tooth blank is large, the transition ramp 374 moves synchronously when the insertion block 37 moves downward. The inclined surface of the transition ramp 374 will press against the inner ring boundary of the tooth blank. When the inclined surface of the transition ramp 374 is pressed, the transition ramp 374 will drive the insertion rod 373 to press against the compression spring inside the insertion slot 372. As the plug-in block 37 moves further downward, the inclined surface of the transition ramp 374 no longer presses against the inner ring of the tooth blank, while the vertical surface on the inclined surface presses against the inner ring of the tooth blank, thus fixing the tooth blank. For tooth blanks of different sizes, the length of the plug-in rod 373 can be adjusted to fix the tooth blank, making it convenient to use. Furthermore, a through hole 375 is provided at the top of the transition ramp 374, and a second rotating belt 376 is provided inside the through hole 375. When the inclined surface of the transition ramp 374 approaches the boundary of the inner ring of the tooth blank, the second rotating belt 376 will press against the boundary of the inner ring of the tooth blank. As the transition ramp 374 moves downward, the second rotating belt 376 will rotate synchronously, thereby eliminating the friction between the transition ramp 374 and the inner ring of the tooth blank and protecting the tooth blank.
