That is, an operator can align and clamp rings with different diameters by using the second positioning device, the second pressing device and the third pressing device, so that the production cost of the whole ring machining system is reduced.

A second aspect of the present invention provides a processing method for a ring member, which is used in the ring member processing system according to any one of the above technical solutions, and the ring member processing system includes: the machining method comprises the following steps of: checking the roundness and the machining allowance of the ring blank to be machined; aligning the ring blank by using a second positioning device, and clamping the upper end face of the ring blank by using a second pressing device; processing the outer wall of the ring blank to a first target size; processing part of the upper end face of the ring blank to a second target size; clamping the processed outer wall of the ring blank by using a third pressing device; roughly machining the inner wall of the ring blank; processing the residual upper end surface of the ring blank to a second target size; cutting the ring blank from the outer wall of the ring blank to obtain a first ring body; turning over the first ring body and placing the first ring body on the main body; aligning the first ring body by using a first positioning device, and clamping the processed outer wall of the first ring body by using a first pressing device; machining the inner wall of the first ring body to a third target size; and machining the end face of the cut part of the first ring body to a fourth target size.

The processing method of the ring piece, provided by the invention, is used for the ring piece processing system in any one of the technical schemes, can effectively improve the processing precision of the ring piece, and particularly can effectively reduce the deformation of the thin-wall ring piece in the processing process and ensure the production cycle of the ring piece for the large-diameter thin-wall ring piece with the outer diameter larger than 1000mm and the ratio of the outer diameter to the inner diameter smaller than 1.2. Specifically, an operator firstly checks the roundness and the machining allowance of the ring blank to be machined, and if the roundness and the machining allowance cannot meet requirements, the ring blank is subjected to flame straightening.

After the ring blank is inspected to be qualified, an operator uses the second positioning device to perform position alignment on the ring blank from the outer wall of the ring blank, and after the alignment is completed, the second pressing device is used for pressing the ring from the upper end face of the ring blank.

After the ring piece is fixed, the processing equipment starts to process the outer wall of the ring piece blank and the upper end face of the ring piece blank which is not shielded by the second pressing device. Specifically, the outer wall of the ring blank is machined to a first target dimension and a portion of the upper end face of the ring blank is machined to a second target dimension. The machining process is divided into two stages, namely a rough machining stage and a finish machining stage. In the rough machining stage, the cutting depth of the cutter is 0.5mm to 3mm, the feeding amount is 0.3mm/r to 0.8mm/r, the cutting speed is 30m/min to 80m/min, the material of the ring blank can be quickly removed, and the size of the outer wall of the ring blank is quickly close to the first target size. And after the rough machining is finished, the finish machining stage is carried out, at the moment, the cutting depth of the cutter is adjusted to be 0.1 mm-0.5 mm, the feeding amount is adjusted to be 0.1 mm/r-0.3 mm/r, the cutting speed is adjusted to be 80 m/min-100 m/min, and the smoothness of the machined surface can be improved by reducing the cutting depth and the feeding amount and improving the cutting speed.

After the outer wall and part of the upper end face of the ring blank are machined, the machined outer wall of the ring blank is clamped by using a third pressing device, the second pressing device is loosened, and then the inner wall of the ring blank is roughly machined. Since the upper end face of the ring blank is not shielded and interfered at the moment, the processing equipment also processes the upper end face of the ring blank shielded by the second pressing device to a second target size.

And after the steps are finished, cutting the ring blank from the outer wall of the ring blank to obtain a first ring body. After the main body is placed on a workbench of the machining equipment, the first ring body is turned over and placed on the main body, the inner wall surface of the main body is attached to the outer wall surface of the first ring body, the rigidity of the weak part of the first ring body is improved, and the deformation of the first ring body in the machining process is reduced. An operator utilizes the first positioning device to finely adjust the position of the first ring body from the outer wall of the first ring body, and after adjustment is completed, the first pressing device is utilized to press the ring body from the upper end face of the first ring body.

After the first ring body is fixed, the machining equipment begins to machine the inner wall and the cut end face of the first ring body, and the inner wall of the first ring body is subjected to finish machining to a third target size. The end face of the cut-off part of the first ring body is machined to a fourth target size, the machining process of the end face of the cut-off part is also divided into rough machining and finish machining stages, and cutting parameters are not described any more.

In any of the above technical solutions, further, the processing method further includes: based on the condition of processing error of the ring piece to be processed, the outer wall of the main body is processed to a first target size, the upper end face of the main body is processed to a second target size, the inner wall of the main body is processed to a third target size, and the lower end face of the main body is processed to a fourth target size.

In the technical scheme, the main body can also be used as an alternative ring piece, and when the ring piece is out of order in the processing process, the ring piece can be directly taken down from the main body to process the main body which is also in an annular structure. Specifically, the outer wall of the main body is machined to a first target size, the upper end face of the main body is machined to a second target size, the inner wall of the main body is machined to a third target size, and the lower end face of the main body is machined to a fourth target size, so that construction period delay is avoided, and the production cycle of the ring piece is guaranteed.

In any of the above technical solutions, further, cutting the ring blank from the outer wall of the ring blank specifically includes: processing a cutting groove on the inner wall of the ring blank; arranging a cushion block in the cutting groove, wherein the thickness of the cushion block is the same as the groove width of the cutting groove; and cutting the ring blank from the outer wall of the ring blank along the extending direction of the groove depth of the cutting groove to obtain a first ring body.

In the technical scheme, before the ring blank is cut from the outer wall, a cutting groove is processed on the inner wall of the ring blank, and a cushion block is arranged in the cutting groove, wherein the thickness of the cushion block is the same as the groove width of the cutting groove. Can make the ring piece can remain stable at the cutting off-process through above-mentioned setting, on the one hand, promoted the surface quality of cutting off department for follow-up when carrying out the processing of cutting off department terminal surface, the cutter moves more steadily, avoids cutting off department surface irregularity to damage the cutter. On the other hand, after the ring blank is cut off through the arrangement of the cushion block, the first ring body cannot directly fall off, and the safety of processing equipment and operators is guaranteed.

In any of the above technical solutions, further, after the third pressing device presses the ring blank, the second pressing device is released.

In the technical scheme, before the inner wall and the residual upper end surface of the ring blank are processed, the second pressing plate of the second pressing device needs to be loosened. And directly loosening the second pressing plate can cause the ring to move, so that the third pressing plate of the third pressing device is required to press the ring blank, and then the second pressing plate of the second pressing device is loosened, so that the position precision of the ring blank is ensured, and the processing quality of the ring is improved.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

A ring machining system 100 and a method of machining a ring provided according to some embodiments of the present invention are described below with reference to fig. 1 to 17.

The first embodiment is as follows:

as shown in fig. 1 to 6, a first embodiment of the present invention provides a ring processing system 100, including: a processing tool 102 and a base assembly 106. Wherein, the processing device 102 is used for processing the ring, and the base assembly 106 is used for clamping the ring.

Specifically, as shown in fig. 1 to 4, the processing apparatus 102 includes a table 104, and the base assembly 106 can be placed on the table 104, and when the base assembly 106 is placed on the table 104, it can be fixed on the table 104 by using a vise, so that the base assembly 106 rotates together with the table 104. The base assembly 106 includes a body 108, as shown in fig. 2, the body 108 is configured as a ring-shaped structure for supporting the ring. When the main body 108 supports the ring, the inner wall surface of the main body 108 is attached to the outer wall surface of the ring, the rigidity of the weak position of the ring is improved, and especially for a large-diameter thin-wall ring with the outer diameter larger than 1000mm and the ratio of the outer diameter to the inner diameter smaller than 1.2, the deformation of the thin-wall ring in the machining process can be obviously reduced.

That is, in the ring machining system 100 provided in this embodiment, the base assembly 106 is disposed on the workbench 104 of the machining device 102, and the shape of the main body 108 of the base assembly 106 at least partially matches the shape of the ring, so that the stability of clamping the ring is effectively improved, and the machining accuracy of the ring is further improved. In addition, the main body 108 of the base assembly 106 can be used for supporting various different ring members, and the clamping tool does not need to be frequently replaced when different ring members are machined, so that the universality of the base assembly 106 is improved, and the machining cost is reduced. Further, when the ring supported by the main body 108 is replaced, since the position of the base assembly 106 relative to the worktable 104 is not changed, the position of the replaced ring is only required to be finely adjusted, and the production cycle is shortened.

Example two:

as shown in fig. 1 to 6, a second embodiment of the present invention provides a ring processing system 100, including: a processing tool 102, and a base assembly 106. Wherein, the processing device 102 is used for processing the ring, and the base assembly 106 is used for clamping the ring.

Specifically, as shown in fig. 1 to 4, the processing apparatus 102 includes a table 104, and the base assembly 106 can be placed on the table 104, and when the base assembly 106 is placed on the table 104, it can be fixed on the table 104 by using a vise, so that the base assembly 106 rotates together with the table 104. The base assembly 106 includes a body 108, as shown in fig. 2, the body 108 is configured as a ring-shaped structure for supporting the ring. When the main body 108 supports the ring, the inner wall surface of the main body 108 is attached to the outer wall surface of the ring, the rigidity of the weak position of the ring is improved, and especially for a large-diameter thin-wall ring with the outer diameter larger than 1000mm and the ratio of the outer diameter to the inner diameter smaller than 1.2, the deformation of the thin-wall ring in the processing process can be obviously reduced, and the processing precision of the ring is improved.

Further, the material of the body 108 is the same as the material of the ring.

Specifically, by setting the material of the main body 108 to be the same as that of the ring, when the ring is out of order during the machining process, the ring can be directly taken down, and the main body 108 which is also in an annular structure is machined, so that the construction period delay is avoided.

As shown in fig. 1 and 4, the plurality of first pressing devices 118 are uniformly distributed along the inner circumferential side of the main body 108, and can press the ring from the outer wall of the ring, and uniformly distribute the clamping force applied to the ring, so as to prevent the ring from deforming.

Specifically, the first adjusting module 114 is a bolt, the distance that the first adjusting module 114 extends out of the first adjusting plate is adjustable, and the ring position can be aligned by adjusting the extending distance of the first adjusting module 114. Because one end of the first adjusting module 114 abuts against the outer wall of the ring, the first adjusting module 114 can also provide a certain radial clamping force to the ring, so as to play a role in assisting in clamping.

Further, as shown in fig. 4 and 6, the first pressing device 118 includes: a first presser plate 120.

As shown in fig. 4, one end of the first pressing plate 120 is configured to abut against the outer wall of the ring, so as to press the ring. The first platen 120 provides a compressive force toward the upper end surface of the body 108.

The second adjusting module 128 is a bolt, the distance that the second adjusting module 128 extends out of the second adjusting plate is adjustable, and the adjustment and alignment of the ring position can be realized by adjusting the extending distance of the second adjusting module 128. Because one end of the second adjusting module 128 abuts against the outer wall of the ring, the second adjusting module 128 can also provide a certain radial clamping force for the ring, and the stability of clamping the ring is improved.

Further, the plurality of second pressing devices 136 are annularly distributed on the workbench 104, and the plurality of second pressing devices 136 are located inside the ring defined by the plurality of second positioning devices 124; the third pressing devices 144 are annularly distributed on the working table 104, and the third pressing devices 144 are located outside the ring formed by the second pressing devices 136.
