Description

Technical Field

[0001] This invention relates to the field of machining technology, and in particular to a machining method and apparatus. Background Technology

[0002] The bend pipe joint is a very important part in the engine, and its machining accuracy requirements are very high. Figure 1 Specific machining data for a bend pipe joint component is shown. For example... Figure 1 As shown, the curved pipe joint part is an irregularly shaped, thin-walled part with an indented inner ball. Its machining process is lengthy, requiring multiple passes on CNC lathes, conventional lathes, and CNC milling machines. Furthermore, it necessitates multiple clamping operations using various specialized fixtures to complete the machining process. Therefore, curved pipe joint parts are particularly prone to problems such as clamping damage, deformation, and impact damage during machining, resulting in low machining efficiency and a part qualification rate of only about 65%.

[0003] However, with the continuous increase in the annual production volume of engines, the demand for processing bend pipe joint parts is also increasing, and existing methods are insufficient to meet the requirements of production efficiency and quality. Therefore, there is an urgent need for a processing method and device that can improve the processing efficiency and pass rate of bend pipe joint parts. Summary of the Invention

[0004] In view of the above-mentioned problems of the prior art, this application provides a processing method and apparatus that can improve the processing efficiency and pass rate of bend pipe joint parts.

[0005] To achieve the above objectives, the first aspect of this application provides a processing method for processing a bend pipe joint part. The part includes a ball segment and a cylindrical segment. The cylindrical segment is disposed on the outer circumferential surface of the ball segment. The ball segment has two planes, which are parallel to an axis and symmetrically arranged on both sides of the axis. A circular through hole is provided at the center of each plane, and the axis of the through hole passes through the center of the ball segment. An inner spherical surface is provided at the middle position of the through hole. The cylindrical segment has a circular connecting hole at its axis, one end of which is located on the end face of the cylindrical segment, and the other end of which communicates with the inner spherical surface. The method includes: fixing a bar stock onto a spindle; processing the cylindrical segment on the bar stock; processing the ball segment on the bar stock, wherein the ball segment is located at the end of the cylindrical segment facing the spindle, and the ball segment is connected to the bar stock on the side away from the cylindrical segment.

[0006] As described above, after fixing the bar stock onto the spindle, by positioning the ball segment at the end of the cylindrical segment facing the spindle, the area of ​​the cylindrical segment requiring machining is fully exposed, facilitating machining. By connecting the ball segment to the bar stock on the side away from the cylindrical segment, areas requiring machining, such as planes, through holes, and the center of the ball segment, are avoided. This allows the part to complete most of the machining steps without being cut from the bar stock (only the area where the outer circumference of the ball segment connects to the bar stock remains unmachined). Therefore, fixing the bar stock effectively fixes the part, reducing the number of clamping operations, improving machining accuracy and efficiency, and consequently increasing the machining efficiency and yield of curved pipe fitting parts, while reducing machining costs. Furthermore, it avoids direct clamping of the part during machining, preventing deformation caused by clamping forces, thus improving machining accuracy, efficiency, and yield.

[0007] As one possible implementation of the first aspect, the cylindrical segment is fixed by a secondary spindle; the position where the ball segment connects to the bar stock is cut off; and the corresponding position where the ball segment connects to the bar stock is machined.

[0008] As described above, while the main spindle fixes the bar stock, the secondary spindle fixes the cylindrical section, allowing the part to be secured from both ends. This makes the part more stable when cutting the connection between the ball segment and the part. Furthermore, fixing the cylindrical section on the secondary spindle exposes the connection point after cutting the part from the bar stock, facilitating subsequent machining of the connection area.

[0009] As one possible implementation of the first aspect, the secondary spindle clamps the cylindrical segment using extended soft jaws.

[0010] As described above, by using extended soft jaws to clamp the cylindrical section, the part can be kept as far away from the sub-spindle as possible, so as to provide enough space for the machining of the part and facilitate the machining of the part.

[0011] As one possible implementation of the first aspect, the cylindrical segment is machined on the bar stock, and the spherical segment is machined on the bar stock, specifically including: turning the outer shape of the cylindrical segment and the spherical segment; milling the two planes; drilling holes in the planes to form the through holes; machining the inner spherical surface on the inner circumferential surface of the through holes; and drilling holes on the end face of the cylindrical segment to form the connecting holes.

[0012] As one possible implementation of the first aspect, it also includes: rough milling and finish milling of the through hole.

[0013] As one possible implementation of the first aspect, a portion of the through hole is located at one end of the inner spherical surface, and another portion is located at the other end of the inner spherical surface; it also includes: after rough milling and finish milling a portion of the through hole, rotating the bar stock 180° to rough mill and finish mill the other portion of the through hole.

[0014] As described above, after rough milling and finish milling a portion of the through hole, the bar stock is rotated 180° so that the other portion of the through hole can be oriented toward the machining tool, so that the other portion of the through hole can be rough milled and finish milled.

[0015] A second aspect of this application provides a processing apparatus for processing a bend pipe joint part, the part comprising a ball segment and a cylindrical segment, the cylindrical segment being disposed on the outer circumferential surface of the ball segment; the ball segment having two planes disposed on it, the two planes being parallel to an axis and symmetrically disposed on both sides of the axis, a circular through hole being disposed at the center of the planes, the axis of the through hole passing through the center of the ball segment, and an inner spherical surface being disposed at the middle position of the through hole; the cylindrical segment having a circular connecting hole at its axis, one end of the connecting hole being located on the end face of the cylindrical segment, and the other end of the connecting hole communicating with the inner spherical surface; comprising: a spindle for fixing a bar stock; and a processing tool for processing the cylindrical segment and the ball segment on the bar stock, the ball segment being located at the end of the cylindrical segment facing the spindle, and the ball segment being connected to the bar stock on the side away from the cylindrical segment.

[0016] As described above, after fixing the bar stock onto the spindle, by positioning the ball segment at the end of the cylindrical segment facing the spindle, the area of ​​the cylindrical segment requiring machining is fully exposed, facilitating machining. By connecting the ball segment to the bar stock on the side away from the cylindrical segment, areas requiring machining, such as planes, through holes, and the center of the ball segment, are avoided. This allows the part to complete most of the machining steps without being cut from the bar stock (only the area where the outer circumference of the ball segment connects to the bar stock remains unmachined). Therefore, fixing the bar stock effectively fixes the part, reducing the number of clamping operations, improving machining accuracy and efficiency, and consequently increasing the machining efficiency and yield of curved pipe fitting parts, while reducing machining costs. Furthermore, it avoids direct clamping of the part during machining, preventing deformation caused by clamping forces, thus improving machining accuracy, efficiency, and yield.

[0017] As a possible implementation of the second aspect, the processing device further includes: a sub-spindle for fixing the cylindrical segment; the processing tool is also used to cut off the position where the ball segment connects to the bar stock; the processing tool is also used to process the corresponding position where the ball segment connects to the bar stock.

[0018] As one possible implementation of the second aspect, the secondary spindle is an extended soft claw.

[0019] As described above, by using extended soft jaws to clamp the cylindrical section, the part can be kept as far away from the sub-spindle as possible, so as to provide enough space for the machining of the part and facilitate the machining of the part.

[0020] A third aspect of this application provides a computer program product including program instructions that, when executed by a computer, cause the computer to perform the method described in any one of the first aspects of this application.

[0021] As described above, after fixing the bar stock onto the spindle, by positioning the ball segment at the end of the cylindrical segment facing the spindle, the area of ​​the cylindrical segment requiring machining is fully exposed, facilitating machining. By connecting the ball segment to the bar stock on the side away from the cylindrical segment, areas requiring machining, such as planes, through holes, and the center of the ball segment, are avoided. This allows the part to complete most of the machining steps without being cut from the bar stock (only the area where the outer circumference of the ball segment connects to the bar stock remains unmachined). Therefore, fixing the bar stock effectively fixes the part, reducing the number of clamping operations, improving machining accuracy and efficiency, and consequently increasing the machining efficiency and yield of curved pipe fitting parts, while reducing machining costs. Furthermore, it avoids direct clamping of the part during machining, preventing deformation caused by clamping forces, thus improving machining accuracy, efficiency, and yield.

[0027] The term "comprising" as used in the specification and claims should not be construed as limiting itself to what follows; it does not exclude other elements or steps.

Thus, the statement "device comprising means A and B" should not be limited to a device consisting solely of components A and B.

[0028] The term "an embodiment" or "an embodiment" as used in this specification means that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in at least one embodiment of the invention. Therefore, the terms "in one embodiment" or "in an embodiment" appearing throughout this specification do not necessarily refer to the same embodiment, but may refer to the same embodiment.

[0029] Figure 1 This is a schematic diagram illustrating the machining of part 40, the bend pipe joint. Figure 1As shown, the bend pipe connector part 40 includes a ball segment 410 and a cylindrical segment 420. The cylindrical segment 420 is located on the outer circumferential surface of the ball segment 410, and its axis passes through the center of the ball segment 410. Two circular planes 411 are provided on the ball segment 410, parallel to the axis and symmetrically arranged on both sides of the axis. A circular through hole 412 is provided at the center of each plane 411, with its axis passing through the center of the ball segment 410. An inner spherical surface 413 is provided in the middle of the through hole 412. A circular connecting hole 421 is provided at the axial center of the cylindrical segment 420. One end of the connecting hole 421 is located on the end face of the cylindrical segment 420, and the other end communicates with the inner spherical surface 413. The connecting hole 421 is divided into two segments along the axis, and the diameter of the segment corresponding to the position of the connecting hole 421 on the cylindrical segment 420 is larger than the diameter of the segment corresponding to the position of the connecting hole 421 on the ball segment 410.

[0030] When machining the bend pipe joint part 40 using existing technology, the machining method involves four CNC lathe operations, combined with a special fixture. In this process, the part is clamped in the fixture, holes are drilled, a ball is removed, and then a through hole is bored. After the fixture is released, the part deforms, causing the machined dimensions to exceed tolerances. Therefore, machining must be performed until the minimum tolerance is reached, and any deformation after release is repaired by polishing to ensure dimensional accuracy. This method is inefficient, frequently results in dents and scratches, and the first-pass yield is only about 65%.

[0031] Below, with reference to the accompanying drawings, possible embodiments of the processing method in this application will be described by way of example.

[0032] Figure 2 This is a flowchart of processing method 10 in this application. Figure 2 As shown, the specific steps of processing method 10 in this application include: Step S110: Fix the bar stock.

[0033] In step S110, the bar stock is fixed on the spindle 210.

[0034] Step S130: Machining cylindrical segment 420 and spherical segment 410.

[0035] In step S130, a cylindrical segment 420 is machined on the bar stock, and a ball segment 410 is machined on the bar stock. The ball segment 410 is located at the end of the cylindrical segment 420 facing the spindle 210, and the ball segment 410 is connected to the bar stock on the side away from the cylindrical segment 420.

[0036] As described above, after fixing the bar stock onto the spindle 210, by positioning the ball segment 410 at the end of the cylindrical segment 420 facing the spindle 210, the area of ​​the cylindrical segment 420 that needs to be machined is fully exposed, facilitating machining of the cylindrical segment 420. By connecting the ball segment 410 to the bar stock on the side away from the cylindrical segment 420, the areas requiring machining, such as the plane 411, through hole 412, and the center of the ball segment 410, can be avoided. This allows the part 40 to complete most of the machining steps without being cut from the bar stock (only the area where the outer circumference of the ball segment 410 connects to the bar stock is not machined). Therefore, fixing the bar stock achieves the same result as fixing the part 40, reducing the number of clamping operations on the part 40, improving the machining accuracy and efficiency, and thus increasing the machining efficiency and yield of the curved pipe joint part 40, while reducing machining costs. Furthermore, it avoids directly clamping the part 40 during machining. This avoids deformation of part 40 due to clamping force, improves the machining accuracy of part 40, and increases the machining efficiency and pass rate of part 40.

[0037] In some embodiments, such as Figure 2 As shown, the processing method also includes: Step S150: Fix cylindrical segment 420.

[0038] In step S150, the cylindrical segment 420 is fixed by the secondary spindle 250.

[0039] Step S170: Disconnect.

[0040] In step S170, the section where the ball segment 410 is connected to the bar is cut off.

[0041] Step S190: Machining and connecting the corresponding positions.

[0042] In step S190, the corresponding position where the ball segment 410 is connected to the bar stock is processed.

[0043] As described above, while the main spindle 210 fixes the bar stock, the secondary spindle 250 fixes the cylindrical section 420, thus allowing the part 40 to be fixed at both ends. This makes the part 40 more stable when cutting the connection between the ball section 410 and the part 40. Furthermore, fixing the cylindrical section 420 on the secondary spindle 250 exposes the connection position after cutting the part 40 from the bar stock, facilitating subsequent processing of the connection area.

[0044] In some embodiments, the sub-spindle 250 clamps the cylindrical section 420 with extended soft jaws. Thus, by using extended soft jaws to clamp the cylindrical section 420, the part 40 can be moved as far away from the sub-spindle 250 as possible, so as to provide sufficient space for the machining of the part 40 and facilitate the machining of the part 40.

[0045] In some embodiments, step S130 specifically includes: machining the outer shape of the cylindrical segment 420 and the spherical segment 410; milling two planes 411; drilling holes in the planes 411 to form through holes 412; machining an inner spherical surface 413 on the inner circumferential surface of the through hole 412; and drilling holes on the end face of the cylindrical segment 420 to form a connecting hole 421.

[0046] In some embodiments, step S130 further includes rough milling and finish milling of the through hole 412.

[0047] In some embodiments, a portion of the through hole 412 is located at one end of the inner spherical surface 413, and another portion is located at the other end of the inner spherical surface 413. Rough milling and finish milling of the through hole 412 specifically involves: after rough milling and finish milling a portion of the through hole 412, rotating the bar stock 180° to rough mill and finish mill the other portion of the through hole 412. Thus, after rough milling and finish milling a portion of the through hole 412, rotating the bar stock 180° allows the other portion of the through hole 412 to face the machining tool 230, enabling rough milling and finish milling of the other portion of the through hole 412.

[0048] The above content, combined with the above text Figures 1-2 The method embodiments of this application are described in detail below. The following, in conjunction with... Figure 3 The apparatus embodiments of this application are described in detail below. It should be understood that the descriptions of the method embodiments correspond to the descriptions of the apparatus embodiments; therefore, any parts not described in detail in the apparatus embodiments can be referred to the foregoing method embodiments.

[0049] Figure 3 This is a schematic diagram of the processing apparatus 20 in this application. Figure 3 As shown, the processing apparatus 20 in this application is used to process the bend pipe joint part 40, including a spindle 210 and a processing tool 230. The spindle 210 is used to hold the bar stock. The processing tool 230 is used to process a cylindrical segment 420 and a ball segment 410 on the bar stock. The ball segment 410 is located at the end of the cylindrical segment 420 facing the spindle 210, and is connected to the bar stock on the side away from the cylindrical segment 420.

[0050] In some embodiments, such as Figure 3 As shown, the processing device 20 also includes a secondary spindle 250, which is used to fix the cylindrical section 420; the processing tool 230 is also used to cut off the position where the ball section 410 is connected to the bar stock; the processing tool 230 is also used to process the corresponding position where the ball section 410 is connected to the bar stock.

[0051] In some embodiments, the sub-spindle 250 is an extended soft jaw. Thus, by using the extended soft jaw to clamp the cylindrical section 420, the part 40 can be moved as far away from the sub-spindle 250 as possible, so as to provide sufficient space for the machining of the part 40 and facilitate the machining of the part 40.

[0052] The above description provides an exemplary account of the processing method and processing apparatus 20 in this application. Below, with reference to the accompanying drawings, a detailed description of the specific steps of the processing method in this application will be given in a particular embodiment.

[0053] Figure 4 This is a flowchart of processing method 30 in the embodiment. Figure 4 As shown, the specific steps of processing method 30 in this embodiment include: Step S301: Fix the bar stock.

[0054] In step S301, a bar stock of suitable size is selected and fixed on the chuck of the spindle 210.

[0055] Step S302, vehicle exterior.

[0056] In step S302, the shapes of the ball segment 410 and the cylindrical segment 420 are machined out. The cylindrical segment 420 is located at the end of the bar stock, and the ball segment 410 is located at the end of the cylindrical segment 420 away from the end of the bar stock. The ball segment 410 is connected to the bar stock at the axial position.

[0057] Step S303: Mill plane 411.

[0058] In step S303, two circular planes 411 are milled on the ball segment 410. The two planes 411 are parallel to the axis plane 411 of the bar stock on both sides of the axis. The distance between the two planes 411 is greater than the diameter of the cylindrical segment 420.

[0059] Step S304, Drill through hole 412.

[0060] In step S304, a through hole 412 is drilled at the center of the plane 411. The diameter of the through hole 412 is smaller than the diameter of the plane 411, and the axis of the through hole 412 passes through the center of the ball segment 410.

[0061] Step S305: Cut the inner spherical surface 413.

[0062] In step S305, a special inner groove cutter is used to carve an inner spherical surface 413 at the middle position of the through hole 412. The center of the inner spherical surface 413 coincides with the center of the spherical part. The size of the inner spherical surface 413 is smaller than that of the through hole 412, so that the through hole 412 retains a section at each end of the inner spherical surface 413.

[0063] Step S306: Rough milling and finish milling of through hole 412.

[0064] In step S306, after rough milling and finish milling a portion of the through hole 412, the bar stock is rotated 180° to rough mill and finish mill the other portion of the through hole 412.

[0065] Step S307: Drill connecting hole 421.

[0066] In step S307, a connecting hole 421 is drilled at the end of the cylindrical segment 420, with the axis of the connecting hole 421 coinciding with the axis of the bar stock. The connecting hole 421 is divided into two sections. First, a hole is drilled at the end of the cylindrical segment 420. After drilling to the connection position between the cylindrical segment 420 and the spherical segment 410, the radius is reduced, and another connecting hole 421 is drilled at the corresponding position on the spherical segment 410, so that the connecting hole 421 communicates with the inner spherical surface 413.

[0067] Step S308: Fix cylindrical segment 420.

[0068] In step S308, the control sub-spindle 250 uses a special extended soft jaw to clamp and fix the cylindrical section 420.

[0069] Step S309: Cut.

[0070] In step S309, the section where the ball segment 410 is connected to the bar is cut off.

[0071] Step S310: Rough and fine machining of the ball segment 410.

[0072] In step S310, the shape of the ball segment 410 is rough-machined and finish-machined to the predetermined size.

[0073] Step S311: Disassemble part 40.

[0074] In step S311, the secondary spindle 250 is controlled to release the extended soft jaws and remove the machined part 40.

[0075] In summary, using the above-mentioned processing method 30, all machining processes can be completed in a single clamping operation. The spindle end uses hard jaws for clamping to complete over 80% of the machining, followed by cutting. The remaining spherical surface is then machined after the sub-spindle is clamped in a suitable position. This integrates the original four machining processes into one, replacing four operators with one, increasing efficiency by approximately 40%. It offers advantages such as shorter processes, lower production and equipment costs, labor savings, and reduced impact damage. Furthermore, one machine can replace four existing machines, eliminating the need for specialized fixtures in the original process; only extended soft jaws are required. Moreover, the change in clamping method and position—from pressing into the ball segment 410 (where the inner spherical surface 413 is carved out to form a thin wall) to clamping the cylindrical segment 420—reduces the deformation of the part from 0.12-0.15 to less than 0.03, increasing the first-pass yield from approximately 65% ​​to over 98%.
