[0002] Gears are mechanical transmission components that transmit power, change speed and direction of rotation through the meshing of teeth. They are widely used in machinery, automobiles, aerospace, watchmaking and other fields. Gear machining is the process of manufacturing gear teeth using machining methods. Its purpose is to enable gears to achieve accurate transmission, power transmission and motion control by precisely machining parameters such as tooth profile, tooth direction and tooth pitch.

[0003] In the existing technology, during the gear processing, a cutting edge is needed to cut the material to be processed to make the gear teeth. However, the material of high-strength gears is relatively hard, and the cutting edge is difficult to cut the material to be processed stably and efficiently. Moreover, collision vibration will be generated when in contact, making it difficult to maintain the stability of the material to be processed and affecting the processing quality. Summary of the Invention

[0004] The purpose of this invention is to solve the problem in the existing technology that in the gear processing process, a cutting edge is needed to cut the material to be processed to make the gear teeth. However, the material of high-strength gears is relatively hard, and the cutting edge is difficult to cut the material to be processed stably and efficiently. Moreover, collision vibration will occur when in contact, making it difficult to maintain the stability of the material to be processed and affecting the processing quality. Therefore, a high-strength gear processing device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-strength gear processing device includes a body and a connecting shaft. The connecting shaft is rotatably disposed inside the body. A workpiece to be processed is fixedly sleeved on the shaft. A cylinder is fixedly connected to the inner wall of the body. A connecting seat is fixedly connected to the piston rod end of the cylinder. A connecting plate is fixedly connected to the top of the connecting seat. A motor is fixedly connected to the bottom of the connecting plate. A slider is slidably disposed on the upper surface of the connecting plate. A cutting tool is fixedly connected to the side wall of the slider. A connecting rod is fixedly connected to the side of the slider opposite to the cutting tool. A sector gear is rotatably fixedly connected to the output shaft of the motor. A moving frame is fixedly connected to the end of the connecting rod opposite to the slider. Multiple teeth are fixedly connected to the inner wall of the moving frame, and the multiple teeth are respectively meshed with the sector gear.

[0007] Preferably, the top inner wall of the connecting plate is provided with a guide groove, and the bottom of the slider is fixedly connected with a guide block, which is slidably disposed on the inner wall of the guide groove.

[0008] Preferably, a water tank is fixedly connected to the upper surface of the machine body, a water delivery hose is fixedly connected to the side wall of the water tank, a water pump is fixedly connected to the top of the slider, the end of the water delivery hose away from the water tank is fixedly connected to the water pump, a connecting pipe is fixedly connected to the side wall of the water pump, and a booster nozzle is provided at the end of the connecting pipe away from the water pump.

[0009] Preferably, a limiting ring is sleeved on the shaft body of the connecting shaft, and a sealing gasket is fixedly connected to the side wall of the limiting ring, and the sealing gasket is pressed against the side wall of the workpiece to be processed.

[0010] Preferably, the inner wall of the limiting ring has a cavity, a metal elastic strip is fixedly connected to the inner wall of the cavity, a limiting plug is fixedly connected to the bottom of the metal elastic strip, a limiting slot is fixedly connected to the shaft of the connecting shaft, and the limiting plug is inserted into the inner wall of the limiting slot.

[0011] Preferably, a pull rod is fixedly connected at the connection between the limiting plug and the metal elastic strip, and the pull rod extends through the cavity to the outside of the limiting retaining ring.

[0012] Compared with the prior art, the present invention provides a high-strength gear processing device, which has the following beneficial effects:

[0013] 1. This high-strength gear processing device, after the workpiece is fitted onto the connecting shaft, pulls the lever to overcome the elasticity of the metal spring strip, retracting the limiting block into the cavity, allowing the limiting retaining ring to slide along the connecting shaft. When the limiting retaining ring is in contact with the side wall of the workpiece, the lever is released, and the metal spring strip pushes the limiting block into the slot, which, together with the sealing gasket, axially presses and fixes the workpiece, ensuring no axial movement during processing and improving processing stability. The connecting shaft is driven by a drive motor inside the machine body to rotate, meeting the needs of different processing stages.

[0014] 2. This high-strength gear processing device uses a motor to drive a sector gear to rotate. The gear teeth mesh with the teeth of the moving frame, pushing the moving frame to the left. The connecting rod drives the slider to slide in the guide groove on the connecting plate, causing the cutting tool bar to feed towards the workpiece for cutting. The meshing of the sector gear with the teeth drives the moving frame to move back and forth, which in turn allows the cutting guide bar to move back and forth for cutting. This improves cutting efficiency while maintaining stability, ensuring the processing effect of the gear.

[0015] 3. This high-strength gear processing device can adjust the height of the cutting tool holder and the feed rate of the cutting tool holder by extending and retracting the piston rod of the cylinder. The connecting seat can improve the stability of the cylinder's drive on the connecting plate.

[0016] 4. This high-strength gear processing device uses cutting fluid from the water tank to enter the water pump through a water delivery hose. After being pressurized, the fluid is sprayed out from the booster nozzle through the connecting pipe to directly flush the cutting area, which can reduce the surface temperature of the workpiece and the cutting guide rod during cutting.
