[0064] The specific working process of the present invention is as follows: the cylindrical part to be processed is sleeved on the second tool bar f1 and is coaxially connected to the second motor k through the clamping device, and then the first motor c, the second motor k, the first linear drive mechanism d, and the second linear drive mechanism l are started, the first motor c drives the second tool bar f1, the tool shaft f2, the first tool bar f3, the first tool bar f3, the tool shaft f2, the second tool bar f1, and the gear shaping cutter e to rotate, the second motor k drives the cylindrical part to be processed to rotate, the first linear drive mechanism d pushes the first slide b2 to move along the guide of the first guide rail b1, the first slide b2 drives the first motor c to move along the guide of the first guide rail b1, the first motor c drives the second The tool bar f1, the tool axis f2, the first tool bar f3, the first tool bar f3, the tool axis f2, the second tool bar f1, the gear shaping cutter e move relative to the cylindrical part to be processed, the first hydrostatic bearing g2, and the second hydrostatic bearing h2. The inner rack of the cylindrical part to be processed is processed by the rotation of the gear shaping cutter e, the movement of the gear shaping cutter e, and the rotation of the cylindrical part to be processed. When the gear shaping cutter e rotates, each tooth of the gear shaping cutter e cuts the cylindrical part to be processed little by little. By rotating the cylindrical part, the inner wall of the cylindrical part to be processed processed by the gear shaping cutter e is in a smooth curved shape and is relatively smooth, thereby realizing the axial cutting of the gear shaping cutter e relative to the workpiece.

[0065] The second linear drive mechanism l is started, and the second linear drive mechanism l drives the second slide j2 to move along the second guide rail j1, thereby realizing radial feeding of the cylindrical part to be processed. When the gear shaping cutter e completes axial processing of the part and needs to withdraw the cutter to realize the next cutting, the second linear drive mechanism l drives the second motor k and the cylindrical part to be processed to move along the second guide rail j1, so that the gear shaping cutter e is separated from the cylindrical part to be processed, thereby preventing the gear shaping cutter e from dragging on the inner wall of the cylindrical part to be processed when withdrawing the cutter, thereby preventing the gear shaping cutter e from burning.

[0066] When the workpiece needs to be processed by the gear shaping cutter e, the first oil pump m1 and the second oil pump m8 are started first. The first oil pump m1 and the second oil pump m8 pump high-pressure oil into the corresponding first oil chamber 1, the second oil chamber 2, the third oil chamber 5, the fourth oil chamber 6 and the first receiving groove 7 through the first oil inlet main pipe m2, multiple first oil inlet branch pipes m3, the second oil inlet main pipe m4, the second oil inlet branch pipe m5, the third oil inlet main pipe m6, the third oil inlet branch pipe m7 and the fourth oil inlet branch pipe m9. Under the action of the high-pressure oil, the first slide b2 and the first guide rail b1 are supported by the high-pressure oil, the second slide j2 and the second guide rail j1 are supported by the high-pressure oil, and the first hydrostatic bearing g2 is supported by the high-pressure oil. The inner wall and the second tool rod f1 are supported by high-pressure oil, and the inner wall of the second hydrostatic bearing h2 and the first tool rod 61 are supported by high-pressure oil, so that the first slide b2, the second slide j2, the second tool rod f1, and the first tool rod f3 are in a suspended state. When the output shaft of the first linear drive mechanism d drives the first slide b2 to move, with the support of high-pressure oil, the first slide b2 carrying the first motor c can slide smoothly on the first guide rail b1, and the second slide j2 carrying the second motor k can slide smoothly on the second guide rail j1, and the second tool rod f1 and the first tool rod f3 can also easily rotate and slide relative to the first hydrostatic bearing g2 and the second hydrostatic bearing h2.

[0067] When the gear shaping cutter e processes the cylindrical part to be processed, the high-pressure coolant is pumped into the second water inlet hole, and enters the first water inlet hole, the connecting groove 4, and the annular groove 5 in sequence along the second water inlet hole, and is finally sprayed out from the water outlet hole 3. The sprayed high-pressure cleaning liquid can cool the inner wall of the part to be processed. The sprayed cleaning liquid hits the inner wall of the part to be processed and then splashes on the gear shaping cutter e, which can cool the blade of the gear shaping cutter e, and the high-pressure coolant can take away the iron chips generated by cutting to prevent the iron chips from affecting the subsequent processing of the gear shaping cutter e; the coolant can be a liquid such as cooling oil or cooling water.

[0068] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention.
