Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the present application.

[0034] The present application will be described in further detail below in conjunction with the drawings:

[0035] The present application aims to provide a machining anti-misoperation method for different sector segments in a whole ring, so as to solve the technical problem in the prior art that the whole ring parts cannot be identified during the machining of the whole ring, resulting in error cutting of the sector parts and making the obtained sector parts unable to meet the design requirements and be scrapped.

[0036] Referring to Figure 1 The present application provides a machining anti-misoperation method for different sector segments in a whole ring, comprising the following steps:

[0037] Step 1: machining a mark hole 3 at the edge of the whole ring, and machining a plurality of inner square holes and outer square holes around the outer wall and the inner wall of the edge of the whole ring, wherein the mark hole 3 is located above one of the inner square holes and the outer square holes on the whole ring;

[0038] Specifically, the inner square holes and the outer square holes machined on the outer wall and the inner wall of the edge of the whole ring are consistent in angular direction.

[0039] Specifically, the mark hole 3 is consistent in angular direction with the corresponding one of the inner square holes and the outer square holes.

[0040] Step 2: taking the mark hole 3 as a reference hole as a mark, segmenting the sector parts along the whole ring to obtain an identification position, and obtaining a first sector 1 and a second sector 2 according to the identification position;

[0041] Specifically, according to Figure 6As shown, the marking hole 3 is used as the reference hole as a mark, and the fan-shaped part is segmented along the entire ring, wherein the fan-shaped part with the marking hole 3 is set as the second fan-shaped part 2, and the second fan-shaped part 2 is used as the reference to obtain a plurality of first fan-shaped parts 1 along the entire ring segmentation, and the second fan-shaped part 2 and the plurality of first fan-shaped parts 1 are processed through step 3 to form the outer shape of the fan-shaped part.

[0042] The sector angle of the first sector 1 and the second sector 2 is 45°.

[0043] Step 3, sequentially processing the segmented first sector 1 and the second sector 2 to form a sector-shaped part shape;

[0044] Specifically, the shape processing process of the first sector 1 is as follows:

[0045] according to Figure 2 and Figure 3 As shown, the inner and outer walls of the first sector-shaped member 1 are processed through step 1 to obtain a plurality of first outer square holes 11 and a first inner square hole 12, and a plurality of first lugs 13 are processed on the first sector-shaped member 1, forming laces between adjacent first lugs 13, and a first mounting hole 14 is processed on each first lug 13, thereby completing the outer shape processing of the first sector-shaped member 1;

[0046] according to Figure 4 and Figure 5 As shown, the shape processing process of the second sector 2 is as follows:

[0047] The inner and outer walls of the second sector-shaped part 2 are processed through step 1 to obtain a number of second external square holes 21 and a second internal square hole 22, and a number of second lugs 23 are processed on the second sector-shaped part 2, lace is formed between adjacent second lugs 23, and a second mounting hole 24 is formed on each second lug 23, completing the shape processing of the second sector-shaped part 2.

[0048] Among them, the lace spacing between the adjacent first lugs 13 and second lugs 23 of the first sector 1 and the second sector 2 is smaller than the lace spacing between adjacent first lugs 13 on the first sector 1 or the lace spacing between adjacent second lugs 23 on the second sector 2.

[0049] Step 4: assemble the segmented first sector 1 and second sector 2 according to the markings on a wire cutting fixture 9 to perform error-proof cutting to obtain different sector parts.

[0050] Specifically, according to Figure 8As shown, the wire cutting fixture 9 includes a positioning base 4, an arc-shaped groove is provided on the positioning base 4, for placing the first sector 1 and the second sector 2 of the entire ring; a plurality of through holes are arranged around the arc-shaped groove, the first lug 13 and the second lug 23 of the first sector 1 and the second sector 2 are positioned on the through holes, and are positioned by inserting a diamond pin 6 into the through holes; a plurality of pressure plates 5 are arranged around the arc-shaped groove for pressing tightly on the first sector 1 and the second sector 2 of the entire ring, and two groups of anti-error pins 7 are also provided on the edge of the positioning base 4, and the positions of the two groups of anti-error pins 7 correspond to the first lug 13 in the middle of the first sector 1 and the second lug 23 in the middle of the second sector 2 for positioning.

[0051] A slit groove 8 is provided in the positioning base 4 between the first sector 1 and the second sector 2 or between adjacent first sector 1 for cutting the first sector 1 and the second sector 2 or adjacent first sector 1 by a cutting mechanism.

[0052] In the anti-error operation, when the diamond pin 6 and the anti-error latch pin 7 are simultaneously inserted into the first lug 13 in the middle of the first sector 1 or the second lug 23 in the middle of the second sector 2, the workpiece clamping and positioning is completed.

[0053] according to Figure 2 and Figure 3 As shown, the first sector 1 has a sector angle of 45°, an irregular end face annular groove, a depth of 34.4mm, a sector chord length of approximately 296mm, a height of 38.1mm, and a maximum thickness of 40.8mm. Seven first external square holes 11 and first internal square holes 12 are distributed on the inner and outer wall surfaces of the first sector 1. The angular relationship between the first external square holes 11 and the first internal square holes 12 is consistent. Six laces are also distributed on the outermost side of the first sector 1, forming five first lugs 13. Each first lug 13 has a first mounting hole 14. The first mounting hole 14 on the first lug 13 in the middle of the first sector 1 is at the same angular position as the corresponding first external square hole 11 and first internal square hole 12. The first mounting holes 14 on the remaining four first lugs 13 are not at the same angular position as the square holes V1 and V2.

[0054] according to Figure 4 and Figure 5 As shown, compared with the first sector 1, the angular positions of the second lugs 23 in two locations of the second sector 2 are changed, and the remaining dimensions and structures are the same as those of the first sector 1.

[0055] During the whole ring processing stage, a marking hole 3 is processed on one of the inner square holes and the upper part of the outer square hole on the outer wall and inner wall of the edge of the whole ring, and the part numbers of the 8 sector segments are marked starting from the marking hole 3, wherein the first to seventh segments are marked as the first sector 1, and the eighth segment is marked as the second sector 2, to indicate the difference between the first sector 1 (7 pieces) and the second sector 2 (1 piece); after the marking is completed, the mounting holes on the lug are processed in two sizes according to the marking hole 3 and the marking, firstly, 8 φ9.27 (+0.05 / 0) uniformly distributed holes (including the process hole position) are processed, and the remaining holes are processed according to φ9.2 (+0.15 / 0) and the lace is milled, according to Figure 7 As shown, the wire cutting fixture 9 is then used to clamp and position the 8 φ9.27 (+0.05 / 0) holes for cutting. The wire cutting fixture 9 is mainly composed of a positioning base 4, an anti-mistaken pin 7, a diamond pin 6, a pressure plate 5 and a hexagonal cylindrical head screw. The positioning base 4 of this fixture is made with a positioning end face and an inner hole positioning stop to limit the radial and axial freedom of the part. Then the diamond pin 6 is inserted into the outer end hole (φ9.2 (+0.15 / 0)) of the part to limit the freedom of the part to rotate around the axis, thereby positioning the part. In order to avoid the situation where the diamond pin 6 is inserted into the wrong positioning hole due to the large number of end holes of the part, an anti-error pin 7 is added to the positioning base 4. The anti-error pin 7 is inserted into the square hole of the part to prevent the part from being clamped incorrectly. If the diamond pin 6 can be inserted into the outer end hole φ9.27 (+0.05 / 0) of the part but the anti-error pin 7 cannot be inserted into the square hole of the part, the part is clamped incorrectly. Only when the diamond pin 6 and the anti-error pin 7 can meet the above requirements at the same time can it be determined that the workpiece clamping and positioning are completely correct. Finally, the entire ring part is completely fixed by the hexagonal cylindrical head screw on the outside and the pressure plate on the inside to complete the wire cutting process. After the cutting is completed, the first sector 1 and the second sector 2 are distinguished by the marking content, which can meet the requirements of rapid identification of parts and ensure the requirements of part processing quality.

[0056] In the present invention, the parts are mounted on the positioning base 1, and the diamond pin 6 is passed through any two mounting holes on the whole ring, and the anti-mistake pin 7 is inserted into the first external square hole 11 or the second external square hole 21. The outer lug of the part is pressed through the φ9.2 (+0.15 / 0) hole with a hexagonal cylindrical head screw, and the pressure plate 5 presses the inner end face of the part. One cutting seam is processed from the cutting seam on the online cutting equipment, and then the part is removed and the remaining seven cutting seams are completed in sequence along the circumference to form seven first fan-shaped parts 1 and one second fan-shaped part 2. Then, the marking content of the part is visually inspected to distinguish the first fan-shaped part 1 and the second fan-shaped part 2, and finally the high-quality processing of the two parts is completed.

[0057] To sum up, the present invention designs an effective anti-error processing process based on the processing characteristics of the first fan-shaped part 1 and the second fan-shaped part 2, and cooperates with a special fixture to complete the processing quickly and accurately, prevent the production of unqualified parts, improve product quality, and also improve work efficiency and reduce labor costs.

[0058] By using the method of designing marking holes in the whole ring processing stage to determine the identification mark positions of several sector segments, the marking holes are used as a reference for the subsequent processing of the outer structure of the sector end, and several evenly distributed holes are processed on the outer structure. According to the angular relationship between the several evenly distributed holes and the square holes, an error-proofing device is designed to realize the processing and cutting of the sector segments, which effectively solves the problem of easy processing errors and unrecognizable problems in the processing of different sector-shaped parts in a whole ring, improves work efficiency, eliminates quality risks, has high technical content and reference value, and also accumulates rich technical experience for the subsequent processing of similar parts.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents. Any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be covered by the scope of protection of the claims of the present invention.
