TECHNICAL FIELD
[0001] The application relates to the technical field of gear machining, in particular to an intelligent hole expanding device and method for gear forging. BACKGROUND
[0002] In the field of high-end equipment manufacturing, gears are the core components of mechanical transmission systems, and the machining precision of the inner holes directly affects the assembly adaptability, transmission efficiency and fatigue resistance of the gears and shaft systems. In the gear forging process, the hole expanding process is a key link for determining the inner hole size precision, shape and position tolerance and surface quality. With the breakthrough of intelligent manufacturing technology, the traditional gear hole expanding process has been difficult to meet the modern production requirements of high precision, high efficiency and low energy consumption, and the technical bottlenecks and industry pain points need to be broken through by intelligent innovation.
[0003] For example, the patent document with the announcement number CN216540966U discloses a hole expanding device for gear forging, which comprises a positioning shaft and a gear. The outer surface of the positioning shaft is fixedly connected with a handle on one side. The end of the handle is sleeved with an anti-skid rubber sleeve. A connecting block is fixedly installed on one side of the positioning shaft. A fixed block is fixedly assembled on the front side wall of the connecting block. A scale rod is fixedly installed on the fixed block. A protective sleeve and a driving motor are arranged on the opposite side of the connecting block. A hole expander is arranged in the protective sleeve. The bottom end of the positioning shaft is inserted into the center shaft position of the gear. The device is simple and convenient to operate, accurate in positioning, good in hole expanding effect and stable in clamping, and can effectively improve the production and machining efficiency of the gear.
[0004] Although the above-mentioned prior art realizes rigid clamping of the machined gear through the setting of the clamping block and the positioning screw, effectively improves the stability of clamping, but in the actual machining process, due to the lack of buffering and damping mechanism in the clamping structure, the strong vibration generated by the hole expander in the cutting process cannot be effectively released. These vibrations are reversely transmitted through the clamping block and accumulated in the machined gear body, causing high-frequency shaking of the gear, which not only aggravates the tool wear, but also easily causes hole expanding deviation, rough hole wall and other machining defects, seriously affecting the hole expanding precision and machining quality, and is difficult to meet the manufacturing requirements of high-precision gear parts.

[0046] Example two: please refer toFigures 1-10 The application further provides a technical scheme, which is different from the technical scheme of the first embodiment. The application provides an intelligent reaming device for gear forging, further comprising a liquid storage cavity 400 arranged in the inside of the pressing head 102, and the inside of the liquid storage cavity 400 stores cutting fluid. The outer surface of the liquid storage cavity 400 is provided with a plurality of arc-shaped liquid holes 401 in communication with the outside. The arc-shaped liquid hole 401 is fixedly connected with a liquid discharge port 406 in the inside. The arc-shaped liquid hole 401 is provided with a ball 408 blocked by the liquid discharge port 406. The inner wall of the liquid discharge port 406 is provided with a plurality of liquid guide pieces 407. The cutting fluid is used when the sawtooth 103 is used to ream the gear workpiece 101. The ball 408 can adsorb the cutting fluid by the surface tension. Under the action of external force, the cutting fluid is slowly released through the liquid discharge port 406 and discharged to the sawtooth 103 through the arc-shaped liquid hole 401.
[0047] Further, the outer surface of the liquid storage cavity 400 is provided with a plurality of inclined liquid holes 402 configured as inclined surfaces and in communication with the arc-shaped liquid hole 401. The arc-shaped liquid hole 401 is fixedly connected with a liquid cylinder 403 in the inside. The top of the liquid cylinder 403 is slidingly connected with a double-head piece rod 404 which can abut against the ball 408. The top of the double-head piece rod 404 is rotatably connected with a roller 405 which can contact the side surface of the ball 408. When the liquid storage cavity 400 is forced to rotate, the centrifugal force is generated to make the cutting fluid flow through the arc-shaped liquid hole 401 and flow into the liquid cylinder 403, so as to abut against the double-head piece rod 404 to move upward and push the ball 408 to move upward to abut against the liquid discharge port 406. At the same time, the cutting fluid passes through the inclined liquid hole 402 to contact the ball 408, and finally slowly discharges through the liquid discharge port 406. After the cutting fluid passes through the inclined liquid hole 402, the roller 405 is abutted to rotate to drive the ball 408 to slowly rotate, so as to increase the escape efficiency of the cutting fluid on the surface of the ball 408.
[0048] Specifically, when the pressing head 102 rotates, the cutting fluid in the liquid storage cavity 400 is affected by the centrifugal force to flow into the arc-shaped liquid hole 401, so as to push the double-head piece rod 404 in the liquid cylinder 403 to move, and then push the ball 408 to move upward to abut against the inner wall of the liquid discharge port 406. At the same time, the cutting fluid also flows out through the inclined liquid hole 402 to impact the roller 405 and then adhere to the surface of the ball 408. Under the action of the centrifugal force, the cutting fluid flows through the ball 408 to flow out through the liquid guide piece 407 to the surface of the sawtooth 103.
[0049] In summary, the centrifugal force generated by the rotation of the pressure head 102 automatically guides the cutting fluid in the liquid storage cavity 400 to the arc-shaped liquid hole 401 and the inclined liquid hole 402, without the need for additional driving devices. The ball 408 adsorbs the cutting fluid through surface tension and slowly moves up to fit the liquid outlet 406 under the push of the double-head piece rod 404, realizing continuous and uniform release of cutting fluid, avoiding the intermittent and waste problems of traditional jet-type liquid supply. The inclined surface design of the inclined liquid hole 402 and the cooperation of the roller 405 make the cutting fluid impact the roller during flow and drive the ball 408 to slowly rotate, greatly increasing the escape efficiency of the cutting fluid on the surface of the ball. The liquid guide sheet 407 further optimizes the flow path to ensure that the cutting fluid efficiently passes through the liquid outlet 406 to cover the surface of the sawtooth 103, realizing precise cooling and lubrication of the tool. The amount of liquid supply changes dynamically with the rotation speed of the pressure head. The greater the centrifugal force, the more sufficient the cutting fluid supply, perfectly matching the reaming speed, avoiding overheating of the tool due to insufficient liquid supply at low speed, and preventing resource waste caused by excessive spraying at high speed, significantly improving processing stability.
