Description

Technical Field

[0001] This application relates to the field of threaded sleeve processing, and more specifically, to a processing fixture for threaded sleeves. Background Technology

[0002] A threaded sleeve is a precision component commonly used in mold making, machinery manufacturing, and industrial assembly. It has an internal thread structure and is typically used for guiding, positioning, or as a threaded insert.

[0003] Current threaded sleeves generally consist of a first section and a second section, with the front end of the first section having a multi-lobed structure. When machining threaded sleeves, a high-hardness cylinder material can be used as the blank. The blank is clamped on a machining fixture, and then notches are cut into the cylinder material by cutting, thus forming the multi-lobed structure.

[0004] However, because the blank for threaded sleeves is made of hollow material, the notched first end of the blank will wobble during machining, making it difficult to achieve the required machining accuracy. Furthermore, if a traditional clamp is used to hold the first end, it can easily cause deformation of the part. Therefore, a suitable clamp for machining threaded sleeves is currently lacking. Utility Model Content

[0005] A primary objective of this application is to overcome at least one of the deficiencies of the prior art and provide a machining fixture for threaded sleeves. This machining fixture can improve the machining accuracy of threaded sleeves while ensuring clamping tightness.

[0006] To achieve the above-mentioned objectives, this application adopts the following technical solution:

[0007] According to one aspect of this application, a machining fixture for a threaded sleeve includes:

[0008] A radial limiting assembly can be disposed at the first end of the threaded sleeve. The radial limiting assembly includes an outer diameter limiting member and an inner diameter limiting member. The outer diameter limiting member is used to limit the outer wall of the threaded sleeve, and the inner diameter limiting member is used to limit the inner wall of the threaded sleeve.

[0009] The clamping assembly includes a first clamping part and a second clamping part, wherein the first clamping part is used to clamp the radial limiting assembly to fix the first end of the threaded sleeve, and the second clamping part is used to clamp the second end of the threaded sleeve.

[0010] According to one embodiment of this application, the inner diameter limiting member includes a plate and a column connected to the plate. The plate is used to abut against the end face of the first end of the threaded sleeve, and the outer wall of the column is used to abut against the inner wall of the threaded sleeve.

[0011] According to one embodiment of this application, the inner diameter limiting member is further provided with a wire saw receiving part for accommodating a wire saw, the wire saw receiving part including a wire saw receiving hole penetrating the plate and a wire saw receiving groove disposed on the outer wall of the column.

[0012] According to one embodiment of this application, the outer diameter limiting member includes a limiting cylinder, the inner wall of which is used to abut against the outer wall of the threaded sleeve.

[0013] According to one embodiment of this application, the clamping assembly includes a base and an adjusting block, the adjusting block being adjustablely disposed on the base along a first direction, a first clamping part being disposed on one of the base and the adjusting block, and a second clamping part being disposed on the other of the base and the adjusting block.

[0014] According to one embodiment of this application, the first clamping part includes a first clamping block and a first fastener. The first clamping block has a first clamping hole, and the radial limiting component can extend into the first clamping hole. The first fastener passes through the first clamping block and extends into the first clamping hole to clamp the radial limiting component.

[0015] According to one embodiment of this application, the inner diameter limiting member includes a first abutting surface, and the outer diameter limiting member includes a second abutting surface. The first abutting surface and the second abutting surface are used to abut against the same hole wall of the first clamping hole.

[0016] According to one embodiment of this application, the second clamping part includes a second clamping block and a second fastener. The second clamping block has a second clamping hole, and the second fastener passes through the second clamping block and extends into the second clamping hole to clamp the second end of the threaded sleeve.

[0017] According to one embodiment of this application, a sliding guide structure extending along a first direction is provided between the seat and the adjusting block. The sliding guide structure includes a guide protrusion and a guide groove. The guide protrusion is disposed in one of the seat and the adjusting block, and the guide groove is disposed in the other of the seat and the adjusting block.

[0018] According to one embodiment of this application, an adjustment structure is provided between the base and the adjustment block. The adjustment structure includes a positioning hole, an adjustment hole disposed along a first direction, and a positioning member. The positioning hole is disposed in one of the base and the adjustment block, the adjustment hole is disposed in the other of the base and the adjustment block, and the positioning member passes through the adjustment hole and the positioning hole.

[0019] An embodiment of the above application has at least the following advantages or beneficial effects:

[0020] This application provides a machining fixture for a threaded sleeve. When machining the notch of the threaded sleeve, the first clamping part and the second clamping part can stably fix both ends of the threaded sleeve, thereby improving the stability of the threaded sleeve during machining and helping to ensure the machining accuracy of the threaded sleeve. Since the first end of the threaded sleeve is limited by a radial limiting component, and the first clamping part fixes the first end of the threaded sleeve by clamping the radial limiting component, deformation of the first end of the threaded sleeve due to compression by the clamping part is avoided. At the same time, when the first end of the threaded sleeve has a tendency to swing, the radial limiting component can effectively limit the sleeve body of the threaded sleeve, reducing the possibility of the first end of the threaded sleeve swinging, and further improving the machining accuracy of the threaded sleeve.

[0038] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this application will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0039] The features, structures, or characteristics described below can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a full understanding of embodiments of this application. However, those skilled in the art will recognize that the technical solutions of this application can be practiced without one or more of the specific details described, or other methods, components, materials, etc., can be employed. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring various aspects of this application.

[0040] The blank for a threaded sleeve is cylindrical in shape. During the machining process, a notch needs to be machined at the first end of the sleeve. To prevent the blank from wobbling during machining, it is typically clamped at both the first and second ends using a fixture. Because the notch is machined at the first end, the structural strength of that end is drastically reduced, making it prone to deformation.

[0041] In view of this, embodiments of this application provide a machining fixture for threaded sleeves, which is used for machining such as Figure 1 The threaded sleeve shown is an example. This machining fixture can improve the machining accuracy of the threaded sleeve while ensuring that it does not deform.

[0042] like Figure 1 As shown, the threaded sleeve 301 includes a first cylindrical section 310 and a second cylindrical section 320 connected to the first cylindrical section 310. The outer diameter of the first cylindrical section 310 is smaller than the outer diameter of the second cylindrical section 320. A notch 311 is provided on the first cylindrical section 310, extending from the first end of the first cylindrical section 310 to the connection between the first cylindrical section 310 and the second cylindrical section 320. The notch 311 can penetrate the cylindrical body of the first cylindrical section 310, and the extending direction of the notch 311 is the same as the length direction of the threaded sleeve 301. There can be multiple notches 311, which are spaced apart along the circumferential direction of the first cylindrical section 310. There can be 2 to 5 notches 311. This application uses 3 notches 311 as an example to describe the structure of the threaded sleeve 301 and the machining fixture 10.

[0043] For ease of explanation, the length direction of the threaded sleeve 301 is defined as the first direction D1, the second direction D2 is defined as the direction perpendicular to the first direction D1, and the third direction D3 is defined as the direction that is perpendicular to both the first direction D1 and the second direction D2.

[0044] like Figure 2 As shown, the threaded sleeve machining fixture 10 of this application embodiment includes: a radial limiting component 100 and a clamping component 200.

[0045] Please combine Figure 4 Reference Figure 2 A radial limiting component 100 is disposed at the first end 301a of the threaded sleeve 301. The radial limiting component 100 includes an outer diameter limiting member 110 and an inner diameter limiting member 120. The outer diameter limiting member 110 is used to limit the outer wall of the threaded sleeve 301. When the cylinder of the threaded sleeve 301 has an outward expansion tendency, the outer diameter limiting member 110 can stop the cylinder of the threaded sleeve 301. Correspondingly, the inner diameter limiting member 120 is used to limit the inner wall of the threaded sleeve 301. When the cylinder of the threaded sleeve 301 has an inward contraction tendency, the inner diameter limiting member 120 can stop the cylinder of the threaded sleeve 301.

[0046] The clamping assembly 200 includes a first clamping part 222 and a second clamping part 212. The first clamping part 222 is used to clamp the radial limiting assembly 100 to fix the first end 301a of the threaded sleeve 301. The second clamping part 212 is used to clamp the second end 301b of the threaded sleeve 301 to fix the second end 301b of the threaded sleeve 301.

[0047] When machining the notch 311 of the threaded sleeve 301, the first clamping part 222 and the second clamping part 212 can stably fix both ends of the threaded sleeve 301, thereby reducing the probability of the threaded sleeve 301 moving during the machining of the notch 311 and helping to ensure the machining accuracy of the threaded sleeve 301.

[0048] Furthermore, since the first end 301a of the threaded sleeve 301 is limited by the radial limiting component 100, and the first clamping part 222 fixes the first end 301a of the threaded sleeve 301 by clamping the radial limiting component 100, deformation of the first end of the threaded sleeve 301 due to compression by the clamping part is effectively avoided. At the same time, when the first end 301a of the threaded sleeve 301 has a tendency to swing, the radial limiting component 100 can effectively limit the cylinder of the threaded sleeve 301, effectively reducing the probability of the first end 301a of the threaded sleeve 301 swinging, and further improving the machining accuracy of the threaded sleeve 301.

[0049] In some embodiments of this application, in order to facilitate the processing of the threaded sleeve 301, the blank intermediate body 302 of the threaded sleeve 301 includes a reserved portion 330 in addition to the first sleeve section 310 and the second sleeve section 320. Figure 3 A schematic diagram of the intermediate body 302 of the threaded sleeve 301 blank is shown. Figure 3 As shown, the reserved portion 330 is located at the end of the second cylindrical section 320 away from the first cylindrical section 310. The reserved portion 330 exists only in the intermediate structure of the blank, and the final threaded sleeve 301 does not include the reserved portion 330. The outer diameter of the reserved portion 330 is larger than the outer diameter of the second cylindrical section 320, and the wall thickness of the reserved portion 330 is larger than the wall thickness of the second cylindrical section 320, giving the reserved section greater structural strength. Therefore, when machining the notch 311, the radial limiting component 100 can be assembled on the first end 301a of the intermediate body 302 of the blank, and the radial limiting component 100 is radially limited by the first clamping part 222. The reserved portion 330 of the intermediate body 302 of the blank is clamped by the second clamping part 212. After machining the notch 311, the reserved portion 330 can be cut off to ensure that the second end 301b of the threaded sleeve 301 does not deform.

[0050] like Figure 4 and Figure 5As shown, in some embodiments of this application, the inner diameter limiting member 120 includes a plate 121 and a column 122 connected to the plate 121. The plate 121 is used to abut against the end face of the first end 301a of the threaded sleeve 301, and the outer wall of the column 122 is used to abut against the inner wall of the threaded sleeve 301.

[0051] Specifically, the plate 121 includes a first surface and a second surface disposed opposite to each other, and a side surface disposed between the first surface and the second surface. A column 122 can be connected to the second surface of the plate 121. The column 122 extends along a first direction D1. An inner diameter limiting member 120 can be inserted into the first end 301a of the threaded sleeve 301. When the inner diameter limiting member 120 is inserted, the second surface of the plate 121 can abut against the end face of the first end 301a of the threaded sleeve 301, and the outer wall surface of the column 122 can abut against the inner wall of the threaded sleeve 301. When the cylinder of the first end 301a of the threaded sleeve 301 has a tendency to swing inward, the outer wall of the column 122 can form a stop against the inner wall of the threaded sleeve 301, thereby reducing the probability of the cylinder of the first end 301a of the threaded sleeve 301 swinging inward.

[0052] like Figure 4 As shown, the outer diameter limiting member 110 includes a limiting cylinder, which can be sleeved on the outside of the first end 301a of the threaded sleeve 301. The inner wall of the limiting cylinder is used to abut against the outer wall of the threaded sleeve 301. When the cylinder of the first end 301a of the threaded sleeve 301 has a tendency to swing outward, the inner wall of the limiting cylinder can form a stop against the outer wall of the threaded sleeve 301, thereby reducing the probability of the cylinder of the first end 301a of the threaded sleeve 301 swinging outward.

[0053] In the embodiments of this application, the outer diameter limiting member 110 and the inner diameter limiting member 120 are separately configured, which facilitates the separate processing of the two.

[0054] Of course, in other embodiments, the outer diameter limiting member 110 and the inner diameter limiting member 120 can also be fixedly connected. Specifically, the inner diameter limiting member 120 includes a plate 121 and a column 122, and the outer diameter limiting member 110 includes a limiting cylinder, which can be sleeved on the outside of the column 122. The limiting cylinder can be fixedly connected to the plate 121 by welding or other means. A gap is formed between the inner wall of the limiting cylinder and the outer wall of the column for the first end of the threaded sleeve 301 to extend into.

[0055] After the first end of the threaded sleeve 301 extends into the gap, the inner wall of the limiting cylinder abuts against the outer wall of the threaded sleeve 301, and the inner wall of the threaded sleeve 301 abuts against the outer wall of the column. Setting the outer diameter limiting member 110 and the inner diameter limiting member 120 in a fixed connection helps improve the clamping stability of the first clamping part on the radial limiting assembly.

[0056] In other words, if the outer diameter limiting member 110 and the inner diameter limiting member 120 are separate components, the first clamping part needs to clamp the outer diameter limiting member 110 and the inner diameter limiting member 120 respectively. If the outer diameter limiting member 110 and the inner diameter limiting member 120 are integrated, the first clamping part can clamp only the outer diameter limiting member 110 or the inner diameter limiting member 120.

[0057] In some embodiments of this application, the notch 311 on the threaded sleeve 301 can be machined by a wire saw. Figure 6 A schematic diagram of the machining fixture and wire saw assembly is shown. Please refer to... Figure 4 , Figure 5 Reference Figure 6 To ensure that the wire saw cutting wire can enter the threaded sleeve 301, the inner diameter limiting member 120 is also provided with a wire saw receiving part 123 for accommodating the wire saw. The wire saw receiving part 123 includes a wire saw receiving hole 1231 penetrating through the plate 121 and a wire saw receiving groove 1232 provided on the outer wall of the column 122. The wire saw cutting wire 400 can pass through the wire saw receiving hole 1231, the wire saw receiving groove 1232 and the second cylinder section 320 in sequence, and finally exit from the second end 301b of the threaded sleeve 301.

[0058] Understandably, the wire saw receiving groove 1232 is opposite to the first cylindrical section 310 of the blank intermediate body 302. When it is necessary to cut the notch 311, the wire saw cutting line 400 moves along the radial direction of the first cylindrical section 310, cutting from the inner wall to the outer wall of the first cylindrical section 310 to form the first cutting slit of the notch 311. Then, the position of the wire saw cutting line 400 is moved to process the second cutting slit of the notch 311. Finally, the connection between the first cutting slit and the second cutting slit is cut off to form the notch 311.

[0059] It should be noted that the number of wire saw receiving parts 123 corresponds one-to-one with the number of notches 311. For example, if the threaded sleeve 301 has 3 segments, 3 notches 311 need to be provided on the first cylinder, and 3 wire saw receiving parts 123 also need to be provided on the inner diameter limiting member 120. As another example, if the threaded sleeve 301 has 4 segments, 4 notches 311 need to be provided on the first cylinder, and 4 wire saw receiving parts 123 also need to be provided on the inner diameter limiting member 120.

[0060] In the embodiments of this application, such as Figure 6As shown, the clamping assembly 200 includes a base 210 and an adjusting block 220. The adjusting block 220 is adjustablely positioned on the base 210 along a first direction D1. A first clamping part 222 is disposed on one of the base 210 and the adjusting block 220, and a second clamping part 212 is disposed on the other. Because the adjusting block 220 is adjustable along the first direction D1, the machining fixture 10 can be used to process threaded sleeves 301 of different lengths, improving the versatility of the machining fixture 10. When processing a threaded sleeve 301 of a shorter length, the position of the adjusting block 220 can be adjusted to reduce the distance between the first clamping part 222 and the second clamping part 212, thereby achieving stable clamping of the threaded sleeve 301 of a shorter length. When it is necessary to process a threaded sleeve 301 of a larger length, the position of the adjusting block 220 can be adjusted to increase the distance between the first clamping part 222 and the second clamping part 212, so as to achieve stable clamping of the threaded sleeve 301 of a larger length.

[0061] like Figure 6 and Figure 7 As shown, in some embodiments of this application, the first clamping part 222 is disposed on the adjusting block 220, and the second clamping part 212 is disposed on the base 210.

[0062] In other embodiments, the first clamping part 222 may also be provided on the base 210, and the second clamping part 212 may be provided on the adjusting block 220.

[0063] like Figure 8 As shown, in some embodiments of this application, the first clamping part 222 includes a first clamping block 2221 and a first fastener 2222. The first clamping block 2221 has a first clamping hole 2223. The radial limiting component 100 can extend into the first clamping hole 2223. The first fastener 2222 passes through the first clamping block 2221 and extends into the first clamping hole 2223 to clamp the radial limiting component 100.

[0064] Specifically, the first fastener 2222 may include multiple fasteners, some of which are used to clamp the inner diameter limiting member 120, and others are used to clamp the outer diameter limiting member 110.

[0065] like Figure 8As shown, when clamping the inner diameter limiting member 120, a first fastener 2222 can abut the inner diameter limiting member 120 against the wall of the clamping hole. That is, the inner diameter limiting member 120 is fixed by the clamping force between the first fastener 2222 and the wall of the first clamping hole 2223. Specifically, one first fastener 2222 can press the inner diameter limiting member 120 against one wall of the first clamping hole 2223 along the second direction D2, and another first fastener 2222 can abut the inner diameter limiting member 120 against the other wall of the first clamping hole 2223 along the third direction D3.

[0066] In other embodiments, when clamping the inner diameter limiting member 120, the clamping of the inner diameter limiting member 120 can also be achieved by abutting with a pair of first fasteners 2222. Specifically, the pair of first fasteners 2222 can be arranged along the second direction D2, and the clamping of the inner diameter limiting member 120 is achieved by the pushing ends of the two first fasteners 2222 approaching each other.

[0067] The clamping method of the outer diameter limiting component 110 can be referred to that of the inner diameter limiting component 120, and will not be repeated here.

[0068] It should also be noted that the first fastener 2222 can be a screw.

[0069] Furthermore, such as Figure 8 As shown, in order to ensure the coaxiality of the inner diameter limiting member 120 and the outer diameter limiting member 110, a first abutting surface 1211 can be provided on the inner diameter limiting member 120, and a second abutting surface 111 can be provided on the outer diameter limiting member 110. The first abutting surface 1211 and the second abutting surface 111 are used to abut against the same hole wall of the first clamping hole 2223.

[0070] Specifically, when the first abutting surface 1211 and the second abutting surface 111 abut against the same wall of the first clamping hole 2223, the outer wall of the inner diameter limiting member 120 column 122 can just limit the inner wall of the threaded sleeve 301, and the inner wall of the outer diameter limiting member 110 can just limit the outer wall of the threaded sleeve 301. This arrangement can prevent the inner diameter limiting member 120 and the outer diameter limiting member 110 from having inconsistent coaxiality after being clamped by the first clamping part 222, further ensuring the machining accuracy of the notch 311.

[0071] Furthermore, the first clamping hole 2223 can be a polygonal hole, that is, the first clamping hole 2223 can include multiple hole walls connected at an angle. The inner diameter limiting member 120 can be provided with one or more first abutting surfaces 1211, which can abut against different hole walls respectively to ensure the clamping stability of the inner diameter limiting member 120. Correspondingly, the outer diameter limiting member 110 can be provided with one or more second abutting surfaces 111, which can abut against different hole walls respectively to ensure the clamping stability of the outer diameter limiting member 110.

[0072] like Figure 8 As shown, in some embodiments of this application, the second clamping part 212 includes a second clamping block 2121 and a second fastener 2122. The second clamping block 2121 has a second clamping hole 2123. The second fastener 2122 passes through the second clamping block 2121 and extends into the second clamping hole 2123 to clamp the second end 301b of the threaded sleeve 301.

[0073] Specifically, the second fastener 2122 clamps the reserved portion 330, the wall thickness of which is greater than that of the second cylindrical section 320, thus reducing the risk of deformation. During clamping, the reserved portion 330 can be abutted against the wall of the second clamping hole by the second fastener 2122.

[0074] It should be noted that, as Figure 8 As shown, a third abutment surface 331 is provided on the reserved part 330. The third abutment surface 331 can be on the same plane as the first abutment surface 1211 and the second abutment surface 111 to ensure that the threaded sleeve 301 does not tilt after being clamped.

[0075] Furthermore, the second clamping hole 2123 can be a polygonal hole, that is, the second clamping hole 2123 can include multiple hole walls connected at an angle. The reserved part 330 can be provided with one third abutment surface 331 or multiple third abutment surfaces 331. The multiple third abutment surfaces 331 can abut against different hole walls respectively to ensure the clamping stability of the threaded sleeve.

[0076] It should also be noted that the second fastener 2122 can be a screw.

[0077] Furthermore, such as Figure 2As shown, a sliding guide structure 230 extending along the first direction D1 is provided between the base 210 and the adjusting block 220. The sliding guide structure 230 includes a guide protrusion 231 and a guide groove 232. The guide protrusion 231 is disposed on one of the base 210 and the adjusting block 220, and the guide groove 232 is disposed on the other. Through the sliding engagement of the guide protrusion 231 and the guide groove 232, the adjusting block 220 can slide along the first direction D1, thereby facilitating the clamping of threaded sleeves 301 of different lengths.

[0079] Furthermore, the adjusting block 220 includes an adjusting block body 221, and a first clamping block 2221 of the first clamping part 222 is disposed on the adjusting block body 221. The adjusting block body 221 can be integrally formed with the first clamping block 2221, or it can be separately disposed from the first clamping block 2221 and then fixedly connected by welding, screwing, or other methods. A guide groove 232 can be disposed on the adjusting block body 221.

[0080] The base 210 includes a base body 211, and a second clamping block 2121 of the second clamping part 212 is disposed on the base body 211. The base body 211 can be integrally formed with the second clamping block 2121, or it can be separately disposed from the second clamping block 2121 and then fixedly connected by welding, screwing or other methods. A guide groove 232 can be disposed on the base body 211.

[0081] like Figure 8 and Figure 9 As shown, in some embodiments, the base 210 further includes a connecting block 213, which is fixedly connected to the base body 211. The connecting block 213 can be fixed to other external processing equipment, thereby fixing the processing fixture 10 to the external processing equipment to ensure the stability of the threaded sleeve 301 during processing.

[0082] In other embodiments, the guide protrusion 231 may also be provided on the adjusting block 220, and the guide groove 232 may be provided on the seat 210.

[0083] Furthermore, such as Figure 8 and Figure 9As shown, an adjustment structure 240 is provided between the base 210 and the adjustment block 220. The adjustment structure 240 includes a positioning hole 241, a plurality of adjustment holes 242 arranged along the first direction D1, and a positioning member 243. The positioning hole 241 is provided in one of the base 210 and the adjustment block 220, and the plurality of adjustment holes 242 are provided in the other of the base 210 and the adjustment block 220. The positioning member 243 passes through the adjustment holes 242 and the positioning hole 241. During adjustment, the adjustment block 220 can be slid out of the positioning adjustment hole 242, and then the positioning member 243 can be inserted into both the positioning hole 241 and the adjustment hole 242 simultaneously, so that the position of the adjustment block 220 relative to the base 210 is fixed.

[0084] In the embodiments of this application, the positioning hole 241 is provided on the base 210, and the plurality of adjustment holes 242 are provided on the adjustment block 220.

[0085] In other embodiments, the positioning hole 241 may also be provided on the adjusting block 220, while a plurality of adjusting holes 242 may be provided on the base 210.

[0086] The positioning hole 241 can be a threaded hole. The positioning element 243 includes a threaded rod and a threaded cap connected to the threaded rod. The threaded cap can be provided with an internal hexagonal slot. The position of the positioning element 243 can be adjusted by an internal hexagonal bolt to adjust the position of the adjusting block 220.

[0087] In summary, the machining fixture 10 of this application embodiment includes a clamping assembly 200 and a radial limiting member. The radial limiting member can be clamped on the first end 301a of the threaded sleeve 301 to reduce the possibility of the first end 301a swinging when machining the notch 311, thus ensuring the machining accuracy of the threaded sleeve 301. Furthermore, the clamping assembly 200 includes a first clamping part 222 and a second clamping part 212. The first clamping part 222 can fix the first end 301a of the threaded sleeve 301 by clamping the radial limiting member, preventing the first end 301a of the threaded sleeve 301 from deforming due to clamping, thereby further improving the machining accuracy of the threaded sleeve 301.

[0088] In addition, since the threaded sleeve 301 can be processed by a wire saw, the inner diameter limiting member 120 can also be provided with a wire saw receiving part 123 for the movement of the wire saw cutting line. Therefore, the inner diameter limiting member 120 can reduce the possibility of deformation of the first end 301a of the threaded sleeve 301 without interfering with the processing of the notch 311 of the threaded sleeve 301.
