[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] like Figures 1 to 8 As shown below, the structure and function of a gear processing equipment will be described in detail.

[0032] A gear processing device includes a device support 11, a rotating bracket 21 rotatably connected to the device support 11, two clamping mechanisms fixedly connected to the rotating bracket 21, a lifting mechanism slidably connected to the device support 11, and a cutting mechanism provided on the lifting mechanism.

[0033] In use, the plate component or the ring component can be clamped by two clamping mechanisms. That is, this device can process circular gears on the ring component, or process the tooth shape on the plane on the plate component to form a rack, etc. The height of the cutting mechanism can be controlled by the lifting mechanism, and the processing position of the cutting mechanism can be adjusted. The cutting mechanism can process inclined teeth, straight teeth and herringbone teeth on the plate component or the ring component to meet different usage requirements.

[0034] A lead screw I 12 is rotatably connected to the device bracket 11, and a power mechanism I that drives the lead screw I 12 to rotate is fixedly connected to the device bracket 11. The power mechanism I is preferably a servo motor.

[0035] A power mechanism II for driving the rotating bracket 21 to rotate is fixedly connected to the device bracket 11. The power mechanism II is preferably a servo motor.

[0036] Two lead screws II 22 are rotatably connected to the rotating bracket 21, and two movable plates 23 are connected between the two lead screws II 22 by threads.

[0037] A power mechanism Ⅲ for rotating a drive screw Ⅱ 22 is fixedly connected to the rotating bracket 21. The power mechanism Ⅲ is preferably a servo motor.

[0038] The clamping mechanism includes a telescopic mechanism I 31. A clamping plate 32 is fixedly connected to the telescopic end of the telescopic mechanism I 31. A threaded plate 33 is rotatably connected to the telescopic end of the telescopic mechanism I 31. Multiple clamping blocks 34 are slidably connected to the clamping plate 32. The multiple clamping blocks 34 are all threadedly connected to the threaded plate 33. A clamping column 35 is fixedly connected to each clamping block 34. A telescopic mechanism II 36 is fixedly connected to each clamping block 34. A clamping cylinder 37 is fixedly connected to the telescopic end of each telescopic mechanism II 36. The two telescopic mechanisms I 31 are respectively fixedly connected to two moving plates 23.

[0039] The lifting mechanism includes a sliding block 41, which is slidably connected to the device bracket 11. The sliding block 41 is threadedly connected to the lead screw I 12. A telescopic mechanism III 42 is fixedly connected to the sliding block 41. A lifting bracket 43 is fixedly connected to the telescopic end of the telescopic mechanism III 42. A deflection motor 44 is fixedly connected to the lifting bracket 43. A deflection block 45 is fixedly connected to the output shaft of the deflection motor 44.

[0040] The cutting mechanism includes a cutting bracket 51, a deflection block 45 slidably connected to the cutting bracket 51, lead screw III 52 and lead screw IV 53 rotatably connected to the cutting bracket 51, the deflection block 45 being threadedly connected to the lead screw III 52, a cutting slider 54 slidably connected to the cutting bracket 51, the cutting slider 54 being threadedly connected to the lead screw IV 53, a cutting motor 55 being fixedly connected to the cutting slider 54, and a cutting tool 56 being fixedly connected to the output shaft of the cutting motor 55.

[0041] A power mechanism IV for rotating a drive screw Ⅲ 52 is fixedly connected to the cutting bracket 51. The power mechanism IV is preferably a servo motor.

[0042] The cutting bracket 51 is fixedly connected to a power mechanism V that drives the lead screw Ⅳ53 to rotate. The power mechanism V is preferably a servo motor.

[0043] In use, the sheet metal part or ring part to be processed is placed between the two clamping mechanisms. When clamping the sheet metal part, such as... Figure 2As shown, four clamping columns 35 are preferably provided. When the power mechanism II is started, the output shaft of the power mechanism II begins to rotate. The output shaft of the power mechanism II drives the rotating bracket 21 to rotate, and the rotating bracket 21 drives the clamping mechanism to rotate. The positions of the four clamping columns 35 are adjusted, and the plate component is placed between the four clamping columns 35. The telescopic mechanism I 31 is started. The telescopic mechanism I 31 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism I 31 drives the clamping plate 32 to move. The clamping plate 32 drives the clamping columns 35 to move, thereby adjusting the position of the clamping columns 35. The threaded plate 33 is rotated. When the threaded plate 33 rotates, it drives multiple clamping columns 35 to move through the threads, thereby adjusting the position of multiple clamping columns 35 so that multiple clamping columns 35 move closer to each other to clamp the plate component.

[0044] Furthermore, the telescopic mechanism II 36 is activated. Telescopic mechanism II 36 can be a hydraulic cylinder or an electric push rod. The telescopic end of telescopic mechanism II 36 drives the clamping cylinder 37 to move, such as... Figure 5 As shown, the clamping cylinder 37 can contact the side of the plate component, that is, the clamping cylinder 37 presses against the side of the plate component to fix and clamp the side of the plate component, thereby completing the clamping of the plate component.

[0045] When clamping the ring component, such as Figure 2 As shown, four clamping posts 35 are preferably provided. When the power mechanism II is started, the output shaft of the power mechanism II begins to rotate. The output shaft of the power mechanism II drives the rotating bracket 21 to rotate, and the rotating bracket 21 drives the clamping mechanism to rotate. The positions of the four clamping posts 35 are adjusted, and the ring component is placed between the four clamping posts 35. The telescopic mechanism I 31 is started. The telescopic mechanism I 31 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism I 31 drives the clamping plate 32 to move. The clamping plate 32 drives the clamping posts 35 to move, thereby adjusting the position of the clamping posts 35. The threaded plate 33 is rotated. When the threaded plate 33 rotates, it drives multiple clamping posts 35 to move through the thread, thereby adjusting the position of multiple clamping posts 35 so that the multiple clamping posts 35 move closer or further away from each other to clamp the ring component.

[0046] Furthermore, the telescopic mechanism II 36 is activated. Telescopic mechanism II 36 can be a hydraulic cylinder or an electric push rod. The telescopic end of telescopic mechanism II 36 drives the clamping cylinder 37 to move, such as... Figure 5 As shown, the clamping cylinder 37 can contact the side of the ring component, that is, the clamping cylinder 37 presses against the side of the ring component to fix and clamp the side of the ring component, thereby completing the clamping of the ring component.

[0047] Once the sheet metal or ring component to be processed is clamped, the power mechanism III can be started. The output shaft of the power mechanism III starts to rotate, which drives the lead screw II 22 to rotate. When the lead screw II 22 rotates, it drives the moving plate 23 to move through the thread, which in turn drives the clamping mechanism to move, thereby adjusting the position of the sheet metal or ring component.

[0048] Furthermore, the power mechanism I is started, and the output shaft of the power mechanism I begins to rotate. The output shaft of the power mechanism I drives the lead screw I12 to rotate. When the lead screw I12 rotates, it drives the sliding block 41 to move through the thread, which in turn drives the lifting mechanism to move. The lifting mechanism drives the cutting mechanism to move, thereby adjusting the position of the cutting mechanism.

[0049] Furthermore, the telescopic mechanism Ⅲ42 is activated. The telescopic mechanism Ⅲ42 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism Ⅲ42 drives the lifting bracket 43 to move, and the lifting bracket 43 drives the cutting mechanism to move, thereby adjusting the height of the cutting mechanism.

[0050] When it is necessary to perform straight tooth machining on a plane or arc surface, the cutting motor 55 is started, and the output shaft of the cutting motor 55 starts to rotate. The output shaft of the cutting motor 55 drives the cutting tool 56 to rotate. The power mechanism V is started, and the output shaft of the power mechanism V starts to rotate. The output shaft of the power mechanism V drives the lead screw IV 53 to rotate. When the lead screw IV 53 rotates, it drives the cutting slider 54 to move through the thread. The cutting slider 54 drives the cutting motor 55 to move, and the cutting motor 55 drives the cutting tool 56 to move, thereby completing the straight tooth machining of the plane or arc surface.

[0051] When it is necessary to process the inclined tooth shape on the arc surface, during the lateral movement of the cutting tool 56, the power mechanism II is started. The output shaft of the power mechanism II drives the rotating bracket 21 to rotate, and the rotating bracket 21 drives the clamped ring component to rotate, thereby causing the ring component to tilt and complete the inclined tooth shape processing of the arc surface.

[0052] When it is necessary to process the herringbone tooth shape on the arc surface, during the lateral movement of the cutting tool 56, the power mechanism II is started. The output shaft of the power mechanism II drives the rotating bracket 21 to rotate, and the rotating bracket 21 drives the clamped ring component to rotate. That is, when the cutting tool 56 moves to the designated position of the ring component, the output shaft of the power mechanism II rotates in the opposite direction to complete the processing of the herringbone tooth shape on the arc surface.

[0053] When it is necessary to process inclined tooth profiles on a plane, the deflection motor 44 is started, and the output shaft of the deflection motor 44 starts to rotate. The output shaft of the deflection motor 44 drives the cutting bracket 51 to rotate, so that the cutting bracket 51 is set at an inclination, thereby causing the cutting tool 56 to generate an inclined motion trajectory to complete the processing of inclined tooth profiles on the plane.

[0054] When it is necessary to machine a herringbone tooth shape on a plane, the deflection motor 44 is started, and the output shaft of the deflection motor 44 starts to rotate. The output shaft of the deflection motor 44 drives the cutting bracket 51 to rotate, so that the cutting bracket 51 is tilted. When the cutting tool 56 moves to the designated position of the plane part, the rotation center of the machining axis of the cutting tool 56 coincides with the rotation center of the output shaft of the deflection motor 44. The output shaft of the deflection motor 44 rotates in the opposite direction to complete the machining of the herringbone tooth shape on the plane.

[0055] Furthermore, the power mechanism IV is activated, and its output shaft begins to rotate. The output shaft of the power mechanism IV drives the lead screw III 52 to rotate. When the lead screw III 52 rotates, it drives the deflection block 45 to move through the thread, thereby adjusting the position of the deflection block 45 and the cutting bracket 51. This, in turn, adjusts the center position of the rotation of the cutting bracket 51 driven by the output shaft of the deflection motor 44, thereby adjusting the rotation center of the deflection motor 44. This, in turn, adjusts when the cutting tool 56 can rotate during processing, ensuring that the cutting tool 56 will not deflect. This adjusts the position where the cutting tool 56 can rotate, switches the direction of the inclined cutting, and thus adjusts the distance of the inclination on both sides of the herringbone tooth shape.
