Description

Technical Field

[0001] This invention relates to the field of gear processing technology, specifically to an intelligent reaming device and method for gear forging. Background Technology

[0002] In the field of high-end equipment manufacturing, gears, as core components of mechanical transmission systems, directly affect the assembly compatibility, transmission efficiency, and fatigue resistance of their internal bore machining accuracy. In gear forging, the reaming process is a crucial step determining the dimensional accuracy, form and position tolerances, and surface quality of the internal bore. With breakthroughs in intelligent manufacturing technology, traditional gear reaming processes can no longer meet the demands of modern production requiring high precision, high efficiency, and low energy consumption. These technological bottlenecks and industry pain points urgently need to be overcome through intelligent innovation.

[0003] For example, patent document CN216540966U discloses a hole-expanding device for gear forging, including a positioning shaft and a gear. A handle is fixedly connected to one side of the outer surface of the positioning shaft, and an anti-slip rubber sleeve is sleeved on the end of the handle. A connecting block is fixedly installed on one side of the positioning shaft, and a fixing block is fixedly assembled on the front side wall of the connecting block. A scale rod is fixedly installed on the fixing block. A protective sleeve and a drive motor are provided on the opposite side of the connecting block. A hole expander is provided inside the protective sleeve, and the bottom end of the positioning shaft is inserted into the central shaft position of the gear. This device is simple and convenient to operate, has accurate positioning, good hole-expanding effect, and stable clamping, which can effectively improve the production and processing efficiency of gears.

[0004] While the aforementioned existing technologies achieve rigid clamping of the machined gears by setting clamping blocks and positioning screws, effectively improving clamping stability, the lack of buffering and vibration reduction mechanisms in the clamping structure means that the strong vibrations generated by the reamer during cutting cannot be effectively released. These vibrations are transmitted in reverse through the clamping blocks and accumulate on the machined gear body, causing high-frequency vibrations in the gear. This not only exacerbates tool wear but also easily leads to machining defects such as reaming deviation and rough hole walls, seriously affecting reaming accuracy and machining quality, making it difficult to meet the manufacturing requirements of high-precision gear parts. Therefore, this application proposes an intelligent reaming device and method for gear forging. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent hole-expanding device and method for gear forging, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent reaming device for gear forging, comprising a base and a pressure head capable of reaming gear workpieces, wherein the surface of the pressure head is fixedly connected with serrations, and further comprising: A movable bracket is positioned above the machine base to support a gear workpiece.

A spring sleeved on the outer surface of the copper rod is connected between the plug and the heater. A sleeve is fixedly connected to the outer surface of the copper rod. A plurality of resistive plates that are slidably connected to the sleeve are fixedly connected to one side of the heater.

[0010] Preferably, it further includes a liquid storage chamber inside the pressure head, and the liquid storage chamber stores cutting fluid. The outer surface of the liquid storage chamber has multiple arc-shaped liquid holes that communicate with the outside. A drain port is fixedly connected inside the arc-shaped liquid holes. A ball blocked by the drain port is set inside the arc-shaped liquid holes. Multiple liquid guide plates are set on the inner wall of the drain port.

[0011] Preferably, the outer surface of the liquid storage cavity is provided with a plurality of inclined liquid perforations with a sloping structure and communicating with the arc-shaped liquid hole. A liquid cylinder is fixedly connected inside the arc-shaped liquid hole. A double-headed rod that can abut against the ball is slidably connected to the top of the liquid cylinder.

[0013] Preferably, a pressure sensor is fixedly connected to the output end of the cylinder, and the bottom of the pressure sensor is fixedly connected to the top of the motor mount. The pressure sensor is used to control the output pressure of the cylinder.

[0014] Preferably, the bottom of the base is fixedly connected with a plurality of feet, the top of the base is fixedly connected with a guide rail for driving the movable bracket to move, a support plate is fixedly connected to one side of the movable bracket, a drive screw is rotatably connected inside the movable bracket, and a slider for supporting the inclined frame is threaded on the outer surface of the drive screw.

[0015] This invention also provides an intelligent hole enlargement method, comprising the following steps: S1. When using the device, first place the gear workpiece that needs to be enlarged on the top of the moving bracket, and then move the gear workpiece to the bottom of the pressure head; S2. Then, the inclined frame is moved close to the tooth groove of the gear workpiece, and then the extension component provides power to the drive component, causing the flexible sheet to deform and extend into the tooth groove of the gear workpiece, thereby increasing the support force with the gear workpiece. S3. Use the pressure head and saw teeth to enlarge the hole of the gear workpiece; S4. The vibration sensor detects the vibration frequency of the gear workpiece and controls the operation of the balancing assembly.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. The combined design of the first and second guide rails enables precise adjustment of the lateral and longitudinal positions of the pressure head, significantly improving the accuracy of hole enlargement. The cooperation between the movable bracket and the guide rails allows the gear workpiece to be quickly moved from the top of the machine base to the processing area, improving workpiece loading and unloading efficiency, separating the processing area from the placement area, and optimizing the workflow. The inclined frame is designed with an inclined surface adapted to the gear tooth groove, and the structure of the extension cylinder and flexible sheet forms a locking support, significantly improving the support strength for the gear workpiece. The silicone oil in the oil tank, in conjunction with the drive component, allows the flexible sheet to adaptively extend and contact the inner wall of the gear tooth groove, effectively absorbing processing vibration and avoiding vibration transmission caused by rigid clamping. The vibration sensor detects the resonant frequency of the gear workpiece in real time, and the silicone oil flow is dynamically adjusted by the balancing component. In the initial stage, the heater heats the copper rod, reducing the silicone oil viscosity and improving flow smoothness; when the vibration increases, heating is automatically stopped, causing the silicone oil viscosity to increase, increasing resistance, enhancing the damping effect, and achieving adaptive vibration adjustment.

[0017] 2. Utilizing the centrifugal force generated by the rotating pressure head, the cutting fluid in the reservoir is automatically guided to the arc-shaped fluid orifice and the inclined fluid perforation, eliminating the need for an additional drive device. The ball adsorbs the cutting fluid through surface tension and, driven by the double-ended blade, slowly moves upward to conform to the drain port, achieving continuous and uniform release of the cutting fluid. This avoids the intermittent and wasteful problems of traditional jet-type fluid supply. The inclined surface design of the inclined fluid perforation, in conjunction with the rollers, causes the cutting fluid to impact the rollers during flow, driving the ball to rotate slowly, significantly increasing the escape efficiency of the cutting fluid on the ball surface. The guide plate further optimizes the flow path, ensuring that the cutting fluid efficiently covers the serrated surface through the drain port, achieving precise cooling and lubrication of the tool. The fluid supply dynamically changes with the pressure head rotation speed; the greater the centrifugal force, the more sufficient the cutting fluid supply, perfectly matching the hole-reaming speed. This avoids tool overheating caused by insufficient fluid supply at low speeds and prevents resource waste caused by excessive spraying at high speeds, significantly improving machining stability.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1-10This invention provides a technical solution: an intelligent reaming device for gear forging, aiming to solve the technical problem of vibration transmission, affecting machining accuracy and tool life caused by rigid clamping in traditional reaming equipment. It includes a base 100 and a pressure head 102 for reaming gear workpieces 101. The surface of the pressure head 102 is fixedly connected with serrations 103. A bracket 104 is fixedly connected to the top of the base 100. A first guide rail frame 105 is fixedly connected to the top of the bracket 104. A second guide rail frame 106 adapted to the first guide rail frame 105 is slidably connected to the top of the first guide rail frame 105. A cylinder 107 adapted to the second guide rail frame 106 is slidably connected to the bottom of the second guide rail frame 106. A motor base 108 is provided at the output end of the cylinder 107. A device for driving the pressure head 102 is fixedly connected inside the motor base 108. The output end of the rotating motor 109 and cylinder 107 is fixedly connected to a pressure sensor 110, and the bottom of the pressure sensor 110 is fixedly connected to the top of the motor base 108. The pressure sensor 110 is used to control the output pressure of the cylinder 107. The lateral position of the pressure head 102 can be adjusted by setting the first guide rail 105, and the longitudinal position of the pressure head 102 can be adjusted by setting the second guide rail 106, thereby improving its accuracy in expanding the hole of the gear workpiece 101. At the same time, the cylinder 107 can provide pressure to the pressure head 102 to forge the gear workpiece 101 for expanding the hole. It can also cooperate with the motor 109 to drive the saw teeth 103 to rotate for expanding the hole. The pressure sensor 110 can detect the pressure value of the pressure head 102 and adjust the output pressure value of the cylinder 107.

[0022] The system also includes a movable bracket 200, which is positioned above the base 100 to support the gear workpiece 101. The top of the movable bracket 200 has a slant frame 205 adapted to the tooth groove of the gear workpiece 101. One end of the slant frame 205 is fixedly connected to multiple extension cylinders 206 that can extend into the tooth groove of the gear workpiece 101. The interior of the slant frame 205 contains an oil tank 207 storing silicone oil, which is connected to the extension cylinders 206 via a conveyor cylinder 211. The outer surface of the extension cylinders 206 is provided with flexible sheets 2 that can extend and abut against the tooth groove of the gear workpiece 101. 16. The inside of the conveying cylinder 211 is provided with a driving assembly for extending the flexible sheet 216. One side of the inclined frame 205 is provided with an extension assembly for promoting the flow of silicone oil and providing power to the driving assembly. By setting the inclined frame 205 to be inclined, it can fit into the tooth groove of the gear workpiece 101. The cooperation with the extension cylinder 206 can improve the support strength of the gear workpiece 101. At the same time, the flexible sheet 216 is provided to cooperate with the driving assembly to abut against the tooth groove of the gear workpiece 101, forming abutment and locking support. The extension assembly can provide power to the driving assembly to improve efficiency.

[0023] The machine base 100 has multiple feet fixedly connected to its bottom, and a guide rail 201 for driving the movable bracket 200 to move is fixedly connected to its top. A support plate 202 is fixedly connected to one side of the movable bracket 200. A drive screw 203 is rotatably connected inside the movable bracket 200, and a slider 204 for supporting the inclined frame 205 is threadedly connected to the outer surface of the drive screw 203. By setting the guide rail 201, the movable bracket 200 can be driven to move, thereby creating two areas on the top of the machine base 100. One area is used to place the gear workpiece 101, and the other area is used to process the gear workpiece 101, improving the efficiency of picking up and placing the gear workpiece 101. The cooperation between the drive screw 203 and the slider 204 can effectively drive the inclined frame 205 to move so that it can be adapted to different gears. The drive screw 203 can be driven to rotate by the drive component.

[0024] It also includes a vibration sensor 300, which can abut against the inner wall of the flexible sheet 216 to detect the resonant frequency of the gear workpiece 101. The inside of the conveyor cylinder 211 is provided with a balancing component, which receives feedback from the vibration sensor 300 and controls the flow resistance of the silicone oil in the oil tank 207. By setting the vibration sensor 300, the vibration frequency of the gear workpiece 101 during processing can be detected, thereby adjusting the damping intensity. The balancing component can change the flow resistance of the silicone oil to improve kinetic energy absorption.

[0025] Furthermore, the drive assembly includes a plug 212 slidably connected inside the feed cylinder 211, and the plug 212 is used to seal the silicone oil in the oil tank 207. A copper rod 213 is fixedly connected to one side of the oil tank 207. A lifting handle 214 is connected inside the extension cylinder 206 via a torsion spring rod 217, and one end of the copper rod 213 can abut against one end of the lifting handle 214. One end of the lifting handle 214 is fixedly connected to an arc-shaped top plate 215 that abuts against the flexible sheet 216, and the vibration sensor 300 is fixedly connected to the arc-shaped top plate 215. The surface of plate 215 abuts against flexible sheet 216. By setting plug 212, the flow of silicone oil can be blocked, so that the flow force of silicone oil will drive plug 212 to move and drive copper rod 213 to move. As copper rod 213 moves, the rocker arm 214 will rotate around torsion spring rod 217 as the central axis, thereby changing the position of arc top plate 215 so that it unfolds and pushes flexible sheet 216 to deform and abut against the inner wall of gear workpiece 101 tooth groove. Under the influence of vibration, plug 212 can transmit kinetic energy for silicone oil to absorb.

[0026] Furthermore, the extension assembly includes a drive motor 209 fixedly connected to one side of the inclined frame 205, a pressure plate 208 for pushing the silicone oil flow is slidably connected inside the oil tank 207, and a screw 210 threadedly connected to the pressure plate 208 is rotatably connected inside the oil tank 207, and the output end of the drive motor 209 is connected to the screw 210. By setting the drive motor 209 to drive the screw 210 to rotate, the position of the pressure plate 208 can be changed, so that it squeezes the silicone oil in the oil tank 207 and flows into the inside of the conveying cylinder 211, thereby pushing the plug 212 to move and providing power to the drive assembly.

[0027] Furthermore, the balancing assembly includes a heater 301 fixedly connected inside the feed cylinder 211, which heats the copper rod 213. A vibration sensor 300 controls the start and stop of the heater 301. The side of the plug 212 in contact with the silicone oil is made of copper. A spring 218, sleeved on the outer surface of the copper rod 213, is connected between the plug 212 and the heater 301. A sleeve 302 is fixedly connected to the outer surface of the copper rod 213. Multiple resistance plates 303, slidably connected to the sleeve 302, are fixedly connected to one side of the heater 301. Because silicone oil has high resistance at room temperature, in the initial stage, the pressure plate 208... Pushing will make it difficult to drive its flexible flow. Heating the copper rod 213 makes the silicone oil conduct heat and facilitates its flow, thereby improving the smoothness of the force movement of the plug 212. As the silicone oil stability increases and the vibration frequency of the gear workpiece 101 increases, the silicone oil stability can be gradually reduced by stopping the heating, thereby increasing its resistance and improving the shock absorption effect. The heater 301 can heat the copper rod 213 and heat the silicone oil through its own efficient heat conduction performance. At the same time, the movement of the sleeve 302 is restricted by the resist plate 303. There is friction between the two, and the friction between the sleeve 302 and the resist plate 303 increases as the temperature decreases.

[0028] Specifically, in use, the gear workpiece 101 to be enlarged is first placed on top of the two support plates 202. Then, the guide rail 201 is operated to drive the two moving brackets 200 to move synchronously, so that the gear workpiece 101 is located below the pressure head 102. Then, the drive screw 203 is operated to rotate, causing the slider 204 to move, which in turn drives the inclined frame 205 to approach the tooth groove of the gear workpiece 101. Then, the drive motor 209 is turned on, which drives the screw 210 to rotate, causing the pressure plate 208 to move, thereby squeezing the inside of the oil tank 207. The fluid inside the oil tank 207 is then transported through the conveyor 211, which in turn causes the plug plate 212 to move under force, causing the copper rod 213 to abut against one end of the lifting handle 214, thereby driving the arc top plate 215 to flip and abut against the flexible plate 216, deforming it and extending it into the tooth groove of the gear workpiece 101, thus improving the pressure. The position of the second guide rail 106 can be adjusted by operating the first guide rail 105 to support the gear workpiece 101. At the same time, operating the second guide rail 106 can drive the position of the cylinder 107. Operating the cylinder 107 can drive the pressure head 102 to move down and approach the gear workpiece 101. Operating the motor 109 can drive the saw teeth 103 to rotate to realize the hole enlargement work on the gear workpiece 101. When the pressure head 102 enlarges the hole of the gear workpiece 101, it will apply a vibration force to it. This vibration force will act on multiple vibration sensors 300. When the vibration is too large, it will control the heater 301 to operate and stop heating the copper rod 213, so that the fluid cools down and the viscosity resistance gradually increases, improving the vibration reduction effect. At the same time, the cooling down of the copper rod 213 after heating will make the sleeve 302 tougher and increase the friction between it and the resist plate 303.

[0029] In summary, the combined design of the first guide rail frame 105 and the second guide rail frame 106 enables precise adjustment of the transverse and longitudinal positions of the pressure head 102, significantly improving the accuracy of hole enlargement. The cooperation between the movable bracket 200 and the guide rail 201 allows the gear workpiece 101 to move quickly to the processing area from the top of the machine base 100, improving workpiece loading and unloading efficiency, separating the processing area from the placement area, and optimizing the workflow. The inclined frame 205 is designed with an inclined surface adapted to the gear tooth groove, and in conjunction with the structure of the extension cylinder 206 and the flexible sheet 216, it forms a locking support, significantly improving the support strength for the gear workpiece 101. The silicone oil in the oil tank 207, in conjunction with the drive assembly, allows the flexible sheet 216 to adaptively extend and abut against the inner wall of the gear tooth groove, effectively absorbing processing vibrations and avoiding vibration transmission caused by rigid clamping. The vibration sensor 300 detects the resonant frequency of the gear workpiece 101 in real time, and dynamically adjusts the silicone oil flow through the balance assembly heater 301, sleeve 302, and resistive plate 303. In the initial stage, heater 301 heats copper rod 213, reducing silicone oil viscosity and improving flow smoothness; when vibration increases, heating is automatically stopped, causing silicone oil viscosity to increase, resistance to increase, enhancing the damping effect, and achieving adaptive adjustment of vibration.

[0030] Example 2: Please refer to Figures 1-10 The present invention also provides a technical solution, which differs from the technical solution of embodiment one as follows: an intelligent hole-expanding device for gear forging, which further includes a liquid storage chamber 400 opened inside the pressure head 102, and the liquid storage chamber 400 stores cutting fluid. The outer surface of the liquid storage chamber 400 is provided with a plurality of arc-shaped liquid holes 401 communicating with the outside. A drain port 406 is fixedly connected inside the arc-shaped liquid holes 401. A ball 408 blocked by the drain port 406 is provided inside the arc-shaped liquid holes 401. A plurality of liquid guiding plates 407 are provided on the inner wall of the drain port 406. The cutting fluid is used when the saw teeth 103 can be used to expand and cut the gear workpiece 101. The ball 408 can absorb the cutting fluid. Relying on the surface tension of its adsorption, it will slowly release the cutting fluid through the drain port 406 and through the arc-shaped liquid holes 401 to the saw teeth 103 under the action of external force.

[0031] Furthermore, the outer surface of the liquid storage chamber 400 is provided with multiple inclined liquid perforations 402, which are inclined and communicate with the arc-shaped liquid holes 401. A liquid cylinder 403 is fixedly connected inside the arc-shaped liquid holes 401. A double-ended blade 404 that can abut against the ball 408 is slidably connected to the top of the liquid cylinder 403. A roller 405 that can contact the side of the ball 408 is rotatably connected to the top of the double-ended blade 404. When the liquid storage chamber 400 is rotated under force, centrifugal force will be generated to supply cutting fluid. The fluid flows through the arc-shaped liquid hole 401 and into the liquid cylinder 403, thereby resisting the upward movement of the double-headed rod 404 and pushing the ball 408 upward to the outlet 406. At the same time, the cutting fluid passes through the inclined liquid perforation hole 402 and comes into contact with the ball 408, and finally slowly exits through the outlet 406. After the cutting fluid passes through the inclined liquid perforation hole 402, it will contact the roller 405 to make it rotate, thereby driving the ball 408 to rotate slowly and increasing the escape efficiency of the cutting fluid on the surface of the ball 408.

[0032] Specifically, when the pressure head 102 rotates, the cutting fluid in the reservoir 400 will be affected by centrifugal force and enter the arc-shaped liquid hole 401, thereby pushing the double-headed rod 404 in the liquid cylinder 403 to move. This causes the double-headed rod 404 to push the ball 408 upward and fit against the inner wall of the drain port 406. At the same time, the cutting fluid will also be discharged through the inclined liquid perforation hole 402 and impact the roller 405 before adhering to the surface of the ball 408. Under the action of centrifugal force, the cutting fluid will pass through the ball 408 and through the guide plate 407 to be discharged to the surface of the serration 103.

[0033] In summary, by utilizing the centrifugal force generated by the rotation of the pressure head 102, the cutting fluid in the reservoir 400 is automatically guided to the arc-shaped liquid hole 401 and the inclined liquid perforation 402 without the need for an additional drive device. The ball 408 adsorbs the cutting fluid through surface tension and slowly moves upward to fit the drain port 406 under the push of the double-headed rod 404, achieving continuous and uniform release of the cutting fluid. This avoids the intermittent and wasteful problems of traditional jet-type fluid supply. The inclined surface design of the inclined liquid perforation 402, in conjunction with the roller 405, causes the cutting fluid to impact the roller during flow and drive the ball 408 to rotate slowly, significantly increasing the escape efficiency of the cutting fluid on the surface of the ball. The fluid guide plate 407 further optimizes the flow path, ensuring that the cutting fluid is efficiently distributed to the surface of the saw teeth 103 through the drain port 406, achieving precise cooling and lubrication of the tool. The fluid supply changes dynamically with the speed of the pressure head. The greater the centrifugal force, the more sufficient the cutting fluid supply, perfectly matching the hole reaming speed. This avoids tool overheating caused by insufficient fluid supply at low speeds and prevents resource waste caused by excessive spraying at high speeds, significantly improving machining stability.

[0034] Example 3: Please refer to Figures 1-10 The present invention also provides a technical solution, which differs from the technical solution of Embodiment 1 as follows: an intelligent hole enlargement method, comprising the following steps: S1. When using, first place the gear workpiece 101 that needs to be enlarged on the top of the two support plates 202, and then operate the guide rail 201 to drive the two moving brackets 200 to move synchronously, so that the gear workpiece 101 is located below the pressure head 102. S2. Then, the drive screw 203 is rotated to move the slider 204, which in turn moves the inclined frame 205 closer to the tooth groove of the gear workpiece 101. Then, the drive motor 209 is turned on to rotate the screw 210, which moves the pressure plate 208, thereby squeezing the inside of the oil tank 207. This causes the fluid inside the oil tank 207 to be transported through the conveyor 211, which in turn causes the plug plate 212 to move under force, causing the copper rod 213 to abut against one end of the rocker arm 214. This drives the arc top plate 215 to flip and abut against the flexible plate 216, causing it to deform and extend into the tooth groove of the gear workpiece 101, thereby increasing the support force with the gear workpiece 101. S3. The position of the second guide rail 106 can be adjusted by operating the first guide rail 105. At the same time, the position of the cylinder 107 can be driven by operating the second guide rail 106. The cylinder 107 can drive the pressure head 102 to move down and approach the gear workpiece 101. The motor 109 can drive the saw teeth 103 to rotate to realize the hole enlargement work on the gear workpiece 101. When the pressure head 102 enlarges the hole on the gear workpiece 101, it will apply a vibration force to it. This vibration force will act on multiple vibration sensors 300. When the vibration is too large, it will control the heater 301 to run and stop heating the copper rod 213. The heat transfer of the fluid in the oil tank 207 is blocked by the plug 212, so that the fluid cools down and the viscosity resistance gradually increases, improving the vibration reduction effect. At the same time, the subsequent cooling of the copper rod 213 will make the sleeve 302 tougher and increase the friction between it and the resist 303. S4. Simultaneously, when the pressure head 102 rotates, the cutting fluid in the reservoir 400 will be affected by centrifugal force and enter the arc-shaped liquid hole 401, thereby pushing the double-headed rod 404 in the liquid cylinder 403 to move. This causes the double-headed rod 404 to push the ball 408 upward and adhere to the inner wall of the drain port 406. At the same time, the cutting fluid will also be discharged through the inclined liquid perforation hole 402 and impact the roller 405 before adhering to the surface of the ball 408. Under the action of centrifugal force, the cutting fluid will pass through the ball 408 and through the guide plate 407 to be discharged to the surface of the serration 103.
