[0130] In actual application of this embodiment, the T guide plate 33 can provide rotational support for the swivel column 35, and the swivel column 35 can provide support for the swash plate 39, so that the swash plate 39 can stably support the serial rod 38, and the serial rod 38 can provide support for the rubber plate 40, and the rubber plate 40 and the swash plate 39 are made of rubber.

[0131] The staff can control the electric push rod 25 to retract under the support of the fixed plate 24 according to the actual needs, so that the electric push rod 25 pulls the rubber disc 26, the connecting column 27, the bevel disc 28, the connecting rod 29 and the cone wheel 30 to move together in the direction close to the fixed plate 24, thereby separating the rubber disc 26 from the rubber disc 40 and the rubber wheel 19, and at the same time separating the bevel disc 28 from the swash plate 39, and moving the cone wheel 30 to the inner side of the rotating ring 34 to fit the rotating ring 34 and the rubber wheel 19, so that the rubber wheel 19 drives the cone wheel 30 to rotate by friction under the drive of the motor 8, so that the cone wheel 30 drives the connecting rod 29, the bevel disc 28, the connecting column 27 and the rubber disc 26 to rotate together under the support of the electric push rod 25 by rotational power, and the cone wheel 30 drives the rotating ring 34 to rotate by friction, so that the rotating ring 34 drives the three T guide plates 33 to rotate along the annular track 32, and the T guide plates 33 will rotate together along the annular track 32. Under the action of external force, the rotating column 35, the series rod 38, the swash plate 39, the rubber disc 40 and the grinding disc 36 are driven to rotate together with the circular track 32 as the center, so that the grinding disc 36 of appropriate specifications is rotated and adjusted to the position above the rubber wheel 19, and at the same time, the electric push rod 25 is controlled to extend, so that it pushes the cone wheel 30 to separate from the rubber wheel 19 and the rotating ring 34, and pushes the rubber disc 26 to fit with the rubber wheel 19 and the rubber disc 40, and at the same time pushes the angled disc 28 to fit with the swash plate 39, so that the rubber wheel 19 uses the rotational power to push the rubber disc 40, the swash plate 39 and the series rod 38 to rotate, and then the swash plate 39 uses the rotational power to drive the rotating column 35 to rotate under the support of the T guide plate 33, so that the rotating column 35 drives the grinding disc 36 of the corresponding arc tooth specification adjusted to the top of the rubber wheel 19 to rotate together, so that the grinding disc 36 can use the rotational power to grind the arc teeth.

[0132] Working principle: First, the CNC gear grinding machine provides the stability of the overall structure by setting up the machine base 1. The machine base 1 not only provides space for installation and protection of various electrical components, but also carries key moving parts, including Y-axis moving stage 5, Z-axis moving stage 6 and X-axis moving stage 9. Each moving stage undertakes different movement functions in specific operations: the Y-axis moving stage 5 is responsible for lifting and lowering, and is used to adjust the height of the Z-axis moving stage 6; the Z-axis moving stage 6 moves along the horizontal Z-axis, and is used to drive the transmission part and the cold blowing part and other components to adjust forward and backward; the X-axis moving stage 9 is responsible for adjusting the position of the gear seat 12 in the horizontal direction, and the motor 11 can rotate on the B-axis to adjust the angle of the gear seat 12. The motor 8 and the rotating rod 17 can cooperate to push the grinding disc 36 to rotate with the C-axis as the center, so that it can accurately grind the grinding disc 36 and the arc teeth.

[0133] Next, the core part of the grinding operation is carried out by three grinding discs 36 driven by the motor 8. These grinding discs 36 can realize the switching of the workstations through the rotary adjustment part, and the arc teeth are ground by the rotary power. The rotary adjustment part includes a rotating part and an adjusting part. The adjusting part pushes the rotating part to rotate by fitting with the transmission part, thereby adjusting the position of the grinding disc 36.

[0134] The power transmission relies on the combination of the pulley 15, belt 16 and rubber wheel 19 driven by the motor 8. The motor 8 transmits the power to the belt 16 by rotating the pulley 15, thereby driving the synchronous rotation of the driven wheel 18. In this process, the high friction of the rubber wheel 19 effectively enhances the power transmission efficiency. The rubber wheel 19 transmits the power to other key components through the friction with the cone wheel 30 and the rotating ring 34, and can push the rotating column 35 and the grinding disc 36 to perform grinding operations.

[0135] The cold blowing part is to ensure the cooling effect during the grinding process and prevent the arc teeth from generating excessive thermal stress during high-speed grinding. The core of the cold blowing part is composed of a rotating rod 17, a driven wheel 18 and a fan blade 20. When the motor 8 is started, the pulley 15 drives the rotating rod 17 to rotate, and the rotating rod 17 drives the fan blade 20 to rotate at high speed, inhaling external air, and blowing cold air to the arc teeth and grinding area through the wind hood 21 and the air guide parts to ensure temperature control during grinding. This can not only prevent overheating, but also eliminate the cooling dead zone in the grinding area, thereby avoiding precision errors and arc tooth damage caused by thermal stress.

[0136] The movement of the rotating column 35 is supported and guided by the T guide plate 33 and the annular track 32. The T guide plate 33 is combined with the annular track 32 to provide stable support and guidance for the rotation of the rotating column 35 and the rotating ring 34, ensuring that the rotating column 35 and the grinding disc 36 can be accurately moved to the specified position at different grinding stages. The electric push rod 25 plays a key role in adjusting the position of the grinding disc 36. It completes the precise alignment between the grinding disc 36 and the gear seat 12 by pushing and pulling the rubber disc 26, the bevel disc 28 and other components.

[0137] When the specific grinding operation begins, the operator first adjusts the alignment of the grinding disc 36 and the arc tooth, and then starts the motor 8 to drive the rubber wheel 19, cone wheel 30 and other components, and transmits power to the rotating grinding disc 36 through the transmission system. The grinding disc 36 contacts the arc tooth and grinds through continuous rotational power to ensure that the surface of the arc tooth is precisely processed. At the same time, the cold blowing system blows cold air in real time to ensure temperature stability during the entire grinding process. At the same time, the transmission machine 13 is started as needed to control the push wheel 14 to push the arc tooth on the tooth seat 12 to rotate and adjust the grinding position.

[0138] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
