Description

Technical Field

[0001] This application relates to the field of flange technology, and more specifically to a flange and its processing method and processing equipment. Background Technology

[0002] Flanges are parts used to connect shafts to each other and are often used for pipeline connections.

[0003] Existing flanges typically include a flange body with a through hole and two connecting holes. The through hole is located between the two connecting holes. When connecting two pipelines, the two flange bodies are respectively fitted onto the two pipelines through the through hole, causing the two flanges to abut against each other. The connecting hole on one flange body is directly opposite the connecting hole on the other flange body. Bolts are then inserted through the connecting holes on both flange bodies to achieve normal abutment between the two flange bodies. However, when existing flanges abut against each other, it is an end-to-end face abutment, and the end faces are all flat. When the end faces of the two flange bodies are abutted by bolts, there may be a gap between the two end faces, causing fluid to leak outward from the gap between the end faces.

[0004] In addition, existing methods and equipment for processing flanges often use equipment with drilling and milling functions to cut the outer contour of the flange body one by one when processing the flange body. After cutting one flange body, another flange body is picked up by a clamping fixture and processed. When processing flange bodies in large batches, the clamping fixture repeatedly picks up and drops back and forth. There is a lot of idle stroke in this picking process, which is not conducive to improving production efficiency and there is room for optimization.

[0005] Therefore, there is a need for a flange that is less prone to fluid leakage, as well as a processing method and equipment for processing the flange that helps improve production efficiency. Summary of the Invention

[0049] Application Overview

[0050] When existing flanges abut against each other, their end faces are aligned, and both end faces are flat. When the end faces of the two flange bodies are abutted by bolts, there may be a gap between the two end faces, causing fluid to leak outward from the gap. In addition, existing methods and equipment for processing flanges often use equipment with drilling and milling functions to cut the outer contour of the flange body one by one. When processing flange bodies in large quantities, the clamping fixture repeatedly grips back and forth, resulting in a lot of idle strokes during this gripping process, which is not conducive to improving production efficiency and has room for optimization.

[0051] Based on the above-mentioned technical problems, this application proposes a flange, a processing method and processing equipment thereof, wherein the flange, processing method and processing equipment thereof have a simple structure, do not involve complex manufacturing processes and expensive materials, and have high economic efficiency. At the same time, for manufacturers, the flange, processing method and processing equipment thereof provided by this application are easy to produce and have low cost, which is more conducive to controlling production costs and further facilitates product promotion and use.

[0052] Schematic flange and its processing method and equipment,

[0053] refer to Figures 1 to 3 A flange according to a preferred embodiment of the present invention.

[0054] Specifically, such as Figure 1 and Figure 2 As shown, the flange includes a flange body 10. One side of the flange body 10 has a snap-fit ​​portion 101, and the side of the flange body 10 facing away from the snap-fit ​​portion 101 has a mating groove 102. The snap-fit ​​portion 101 and the mating groove 102 are arranged coaxially. In this embodiment, the snap-fit ​​portion 101 is a circular protrusion, and the mating groove 102 is a circular groove. The height of the circular protrusion is equal to the thickness of the circular groove. It should be noted that, due to the presence of the circular protrusion, when the internal expansion assembly in the processing equipment used to process the flange clamps the flange body 10 in an internal expansion manner, the internal expansion assembly is spaced a predetermined distance from the bottom surface of the flange. This ensures that when the grinding device grinds the side of the flange body 10 with the mating groove 102, the grinding wheel in the grinding device is less likely to interfere with the internal expansion assembly.

[0055] In addition, one cross-sectional shape of the flange body 10 is rhomboid, and the four corners of the rhomboid are all rounded. It should be noted that since the flange body 10 is rhomboid in shape, it provides the conditions for cutting multiple flange bodies 10 in a single clamping operation.

[0056] In addition, the flange body 10 has a first connecting hole 103 and two second connecting holes 104. The central axis of the first connecting hole 103 coincides with the intersection of the two diagonals of the rhombus, and the first connecting hole 103 is located between the two second connecting holes 104. The snap-fit ​​part 101 is arranged coaxially with the first connecting hole 103. The flange body 10 is fixedly installed on the corresponding pipeline through the first connecting hole 103, and the two flanges are connected through the second connecting holes 104.

[0057] It should be noted that in the actual pipeline connection process, such as Figure 3As shown, when one flange body 10 has the snap-fit ​​portion 101 on one side and the other flange body 10 has the mating groove 102 on the other side, the snap-fit ​​portion 101 on one flange body 10 extends into the mating groove 102 on the other flange body 10, and the side of the snap-fit ​​portion 101 on one flange body 10 fits against the groove surface of the mating groove 102 on the other flange body 10, and the end of the snap-fit ​​portion 101 fits against the bottom surface of the mating groove 102. It is easy to see that when the snap-fit ​​portion 101 extends into the mating groove 102, it forms a labyrinth seal. Fluid needs to pass through the gap between the snap-fit ​​portion 101 and the mating groove 102 to leak out, which helps to avoid fluid leakage. Compared with the design of the end face being flat in the prior art, the embodiment of this application has the advantage that fluid is not easily leaked when flanges are connected.

[0058] Figure 4 The illustration shows a preferred embodiment of a flange manufacturing method according to the present invention. The manufacturing method is used to add the flange, specifically:

[0059] S1: Mill the straight side surface and grind the bottom surface;

[0060] The straight sides of multiple flange blanks arranged in parallel are cut by a milling cutter, and the bottom surfaces of the multiple flange blanks arranged in parallel are rough and fine ground by a grinding wheel.

[0061] More specifically, the flange body 10 is placed on the feeding belt of the outer contour processing equipment by a robotic arm. It should be noted that multiple flange blanks placed on the feeding belt are arranged side-by-side and spliced ​​to form a parallelogram. Subsequently, the multiple flange blanks are simultaneously lifted to a predetermined height by an internal expansion assembly, maintaining the overall shape of the parallelogram. One flange blank is held in place by an abutment. Two spaced-apart milling cutters simultaneously cut both sides of the parallelogram-shaped flange blank. After the two milling cutters have partially cut the flange blank, the bottom surface of the parallelogram-shaped flange blank is rough-ground along the cutting path of the milling cutters using a grinding wheel. After the milling cutter and the grinding wheel have moved a predetermined distance, the two straight sides of the multiple flange blanks, which are generally parallelogram-shaped, are cut. At the same time, the bottom surface of the multiple flange blanks is rough-machined. Subsequently, by moving and rotating the inner expansion assembly, the multiple flange blanks are rotated by a predetermined angle and spliced ​​to form another parallelogram, exposing the other two straight sides. At this time, the grinding wheel first contacts the flange blank and performs fine grinding on the bottom surface of the parallelogram-shaped flange blank. Then, the two milling cutters cut the other two sides of the parallelogram-shaped flange blank along the movement direction of the grinding wheel, thereby achieving the remaining cutting of the four straight sides of the flange body 10 and the grinding of the bottom surface. Compared to the prior art of cutting flanges one by one, the embodiments of this application adopt the method of simultaneously clamping multiple flanges and having the milling cutter cut the straight side of multiple flanges in parallelogram shape along the same straight line. The idle stroke of the milling cutter between two flanges is small, and the utilization rate is high. In addition, the milling cutter is closely connected to the grinding wheel, which further improves the processing efficiency.

[0062] S2: Mill the curved side surface and the first connecting hole 103;

[0063] The arc-shaped side of the multiple flange blanks arranged in layers is cut by a milling cutter, and the first connecting hole 103 of the multiple flange blanks arranged in layers is precision machined by a milling cutter.

[0064] Specifically, a clamp on a milling and drilling machine passes through the second connecting hole 104 on the flange body 10 and presses together multiple flange blanks arranged in a stacked manner. One or more milling cutters simultaneously cut the outer contours of the multiple flange blanks. Since the straight side of the flange blanks has been cut in step S1, only the curved side of the flange blanks is cut here, and the cutting allowance is small. At the same time, while cutting the curved side of the flange blanks, the first connecting hole 103 of the multiple flange blanks arranged in a stacked manner is rough machined by a drill bit. After the cutting of the curved side of the multiple flange blanks is completed, the first connecting hole 103 after rough machining is finished by a milling cutter. Compared with the prior art, cutting multiple flange blanks simultaneously helps to improve processing efficiency.

[0065] S3: Milling the snap-fit ​​part 101, the top surface and the mating groove 102;

[0066] The snap-fit ​​portion 101 and the mating groove 102 are cut simultaneously by two milling cutters, and the top surface is cut by one milling cutter.

[0067] A flange blank is clamped by a fixture, and milling cutters at both ends of the flange blank cut the snap-fit ​​part 101 and the mating groove 102 respectively. Due to the use of synchronous cutting, the processing efficiency is improved.

[0068] S4: Thread machining of the second connecting hole 104;

[0069] The second connecting hole 104 on the flange blank is machined with an internal thread using a tap.

[0070] This step is a standard technical method and will not be described in detail here. It involves tapping the flange blank one by one with a tap.

[0071] Figures 5 to 11 The figure illustrates a flange processing device according to a preferred embodiment of the present invention. The flange processing device is used to complete step S1 of the flange processing method described above. The processing device is the outer contour processing device, which includes a base 20, a conveying device 30, a clamping device 40, two milling devices 501, and a grinding device 502.

[0072] Furthermore, such as Figure 5 As shown, the conveying device 30 is disposed on the base 20. The conveying device 30 includes a feeding belt 301. Each flange body 10 is placed on the feeding belt 301, and each flange body 10 abuts against each other and splices together to form a parallelogram.

[0073] Specifically, the conveying device 30 further includes several rollers (not shown in the figure), which are rotatably mounted on the base 20. The feeding belt 301 is sleeved on the rollers, and at least one roller is connected to the shaft of a first rotary motor (not shown in the figure). When the shaft of the first rotary motor rotates, the feeding belt 301 moves in the direction of rotation of the shaft of the first rotary motor. In addition, a first baffle 302 is provided on both sides of the feeding belt 301. The width of the first baffle 302 is equal to the distance between the two sides of the flange body 10. When the flange body 10 is placed on the feeding belt 301, the two sides of the flange body 10... The sides are respectively attached to the corresponding first baffle 302; in addition, one end of the feeding belt 301 is a feed port, and the other end of the feeding belt 301 is provided with a second baffle 303. When the shaft of the first rotary motor rotates, the flange body 10 placed on the feeding belt 301 moves with the feeding belt 301, and at a certain moment, one flange body 10 abuts against the second baffle 303, and the remaining flange bodies 10 placed on the feeding belt 301 abut against the adjacent flange bodies 10, and automatically splice to form a parallelogram, so that the clamping device 40 can clamp each flange body 10 at a predetermined position.

[0074] Furthermore, to grip the parallelogram-shaped flange body 10 placed on the feeding belt 301, as follows: Figure 5 and Figure 6 As shown, the clamping device 40 includes a plurality of internal expansion components 401, which are movably mounted on the base 20. The movement direction of the internal expansion components 401 is the length, width and height direction of the base 20. Each internal expansion component 401 corresponds to a flange body 10. Each internal expansion component 401 is located above the flange body 10. The clamping device 40 clamps or releases the flange body 10.

[0075] Specifically, the clamping device 40 includes a first moving component 402, such as... Figure 7As shown, each of the internal expansion components 401 includes two contact members 4011, a first moving member 4012, a stop member 4013, a connecting member 4014, and a first lifting drive device 4015. Each contact member 4011 has a through hole with a first conical surface 40111 on one side. The first moving member 4012 is generally rod-shaped, with a second conical surface 40121 at one end. The end of the first moving member 4012 with the second conical surface 40121 extends into the through hole, and the second conical surface 40121 fits against the first conical surface 40111. The other end of the first moving member 4012 passes through the stop member 4013 and is rotatably mounted on the connecting member 4014 via a bearing. The connecting member 4014 is fixedly connected to the push rod of the first lifting drive device 4015, and the fixed connection method includes, but is not limited to, welding. Specifically, the... The connector 4014 includes a housing 40141 and a cover 40142. The housing 40141 has an open accommodating cavity (not shown in the figure) at the end opposite to the first lifting drive device 4015. The accommodating cavity is used to place the bearing connected to the first moving component 402. The cover 40142 is fixedly connected to the housing 40141 and closes the opening of the accommodating cavity. The fixed connection method includes, but is not limited to, welding. The abutment 4013 is fixedly connected to the first moving component 402. The fixed connection method includes, but is not limited to, welding. The abutment 4013 is located between the contact 4011 and the connector 4014, and the abutment 4013 abuts against the contact 4011. The first lifting drive device 4015 is mounted on the first moving component 402 and moves with it. The first lifting drive device 4015 includes, but is not limited to, an electric push rod. When the first moving component 402 is activated, each clamping device 40 extends into the first connecting hole 103 of the corresponding flange body 10. When the push rod of the first lifting drive device 4015 is activated, the two contact members 4011 either engage with or separate from the first connecting hole 103. Specifically, when the first lifting drive device 4015 moves upward, the two contact members 4011 move in opposite directions and tighten the corresponding flange body 10. At this time, when the first moving component 402 is activated, it drives each clamping device 40 to move and moves the flange body 10 away from the feeding belt 301, and moves the flange body 10 above the milling device 501 and the grinding device 502. It should be noted that during this movement, the first moving component 402 moves only along the height and width directions of the base 20. Therefore, when the multiple flange bodies 10 that have been spliced ​​to form a parallelogram move above the milling device 501, they still maintain the parallelogram arrangement.

[0076] Specifically, to enable the internal expansion component 401 to move in the width and height directions of the base 20, such as... Figure 5 As shown, the flange processing equipment includes a stand 201, which is vertically arranged on the top surface of the base 20 and fixedly connected to the base 20. The fixed connection method includes, but is not limited to, welding. The first moving component 402 includes an extension frame 4021 and a first linear module 4022. The extension frame 4021 is arranged perpendicularly to the stand 201, and the orientation of the extension frame 4021 is the width direction of the base 20. The first linear module 4022 is disposed on the extension frame 4021. The first linear module 4022 includes a slider 40221, which moves with the belt 40222 in the first linear module 4022 and reciprocates along the width direction of the base 20.

[0077] In addition, such as Figure 5 As shown, the first moving component 402 further includes a second lifting drive device 4023. The second lifting drive device 4023 includes, but is not limited to, an electric push rod. The second lifting drive device 4023 is fixedly installed on the slider 40221 of the first linear module 4022 and moves along the width direction of the base 20 following the slider of the first linear module 4022. Each of the inner expansion components 401 is fixedly installed on the second lifting drive device 4023 and moves up and down following the second lifting drive device 4023.

[0078] Furthermore, such as Figure 5 As shown, the milling device 501 is movably mounted on the base 20, and the moving direction of the milling device 501 is the length direction of the base 20. The milling device 501 and the feeding belt 301 are arranged at intervals. Each milling device 501 includes a milling cutter (not shown in the figure). When the clamping device 40 clamps the flange body 10 and moves a predetermined distance along the height and width directions of the base 20, the milling device 501 is located below the inner expansion assembly 401, and each flange body 10 is placed between two milling cutters, and the milling cutter is in contact with or separate from the side of the flange body 10.

[0079] Specifically, to enable the milling device 501 to move along the length direction of the base 20, such as Figure 5 and Figure 8As shown, the flange processing equipment includes two spaced-apart second lead screws 503, which are rotatably mounted on the base 20. The orientation of the second lead screws 503 is along the length direction of the base 20. Each second lead screw 503 has a second gear 504 at one end and a second rotary motor 506 at the end of the second lead screw 503 with the second gear 504. A third gear 505 is provided on the shaft of the second rotary motor 506. The third gear 505 is located between the two second gears 504 and meshes with both second gears 504 simultaneously. Each second lead screw 503 is provided with a milling device 501. When the second rotary motor 506 rotates, the two milling devices 501 move on the corresponding second lead screw 503 to achieve movement along the length direction of the base 20 and cut the two straight sides of the multiple flange bodies 10 arranged in a parallelogram.

[0080] To prevent the multiple flange bodies 10 arranged in a parallelogram from rotating during the cutting process, such as Figure 10 and Figure 11 As shown, the flange processing equipment also includes two abutment members 507. Both abutment members 507 are movably mounted on the base 20. When the inner expansion assembly 401 moves directly above the milling device 501, the abutment member 507 abuts against one of the flange bodies 10. More specifically, each end of one of the multiple flange bodies 10, which are generally parallelogram-shaped, is provided with an abutment member 507. Figure 8 and Figure 10 As shown, when the milling device 501 and the grinding device 502 cut in a direction away from the second rotary motor 506, the abutment 507 near one end of the second baffle 303 abuts against the flange body 10 located at one end of the parallelogram, while the other abutment 507 separates from the flange body 10 and does not interfere with the milling device 501 and the grinding device 502, and the remaining flange bodies 10 are difficult to rotate after being subjected to force due to mutual abutment; Figure 8 and Figure 11 As shown, when the milling device 501 and the grinding device 502 are cutting in the direction of the second rotary motor 506, the abutment 507 at one end away from the second baffle 303 abuts against the flange body 10 located at one end of the parallelogram, while the other abutment 507 separates from the flange body 10.

[0081] In addition, the grinding device 502 is movably mounted on the base 20, and the direction of movement of the grinding device 502 is the length direction of the base 20. In the length direction of the base 20, the grinding device 502 and the milling device 501 are spaced apart by a predetermined distance. The grinding device 502 and the milling device 501 move synchronously. The grinding device 502 includes a grinding wheel (not shown in the figure), and the grinding wheel abuts against or separates from the bottom surface of the flange body 10.

[0082] Specifically, the grinding device 502 is mounted on the second lead screw 503 and threadedly connected to it. The grinding device 502 is located at the end of the milling device 501 opposite to the second baffle 303. When the second lead screw 503 rotates, both the milling device 501 and the grinding device 502 move synchronously on the second lead screw 503. While or after the two milling cutters are cutting the two straight sides of the flange body 10, the grinding wheel immediately performs rough grinding on the bottom surface of the flange body 10. Due to the use of the internal expansion component 4... 01. The flange body 10 is clamped, and the movement of the milling cutter and the grinding wheel does not interfere with the movement of the inner expansion assembly 401. By simultaneously grinding the bottom surface of the flange body 10 while cutting the side of the flange body 10, production efficiency can be improved. By arranging multiple flange bodies 10 side by side and splicing them to form a parallelogram, it is possible for the two milling cutters to move only along the length direction of the base 20 and remain in the cutting state for a long time, cutting the two straight side surfaces of each flange body 10 in sequence. The idle stroke of the tool is small throughout the process, and the time is used efficiently.

[0083] It should be noted that after the milling device 501 and the grinding device 502 perform cutting on the two straight sides and rough grinding on the bottom surface of the multiple flange bodies 10 arranged in a parallelogram, both the milling device 501 and the grinding device 502 are located at the end of the base 20 where the second baffle 303 is located. However, for the multiple flange bodies 10 arranged in a parallelogram, it is also necessary to cut on the other two straight sides and perform fine grinding on the bottom surface. It should be added that the reason for the... The bottom surface of the flange body 10 is precision machined because when the two flanges are mated, the bottom surface of the flange body 10 serves as the mating surface and as the reference surface. The higher its accuracy, the easier it is to ensure the perpendicularity between the first connecting hole 103 and the bottom surface. Therefore, the bottom surface of the flange body 10 is first rough ground and then precision ground. The two straight side surfaces of the flange body 10 have no significant role in actual assembly, and therefore the dimensional accuracy requirement is low, so only one cutting is performed.

[0084] To cut the other two straight sides, each flange body 10 needs to be rotated by a predetermined angle to splice together to form another parallelogram and expose the remaining two unprocessed straight sides.

[0085] To ensure that each flange body 10 rotates synchronously by a predetermined angle, such as Figure 6 As shown, the abutment 4013 has a first groove 40131 at one end opposite to the contact member 4011. The first moving component 402 also includes a rack 4024 and a linear drive device 4025. The rack 4024 is slidably disposed in the first groove 40131. The first moving component 4012 has a first gear 40122. It should be noted that when the two contact members 4011 are fastened to the first connecting hole 103, the first gear 40122 meshes with the rack 4024. The abutment 4013 in the inner expansion component 401 located at one end of the parallelogram is provided with the linear drive device 4025. The linear drive device 4025 includes, but is not limited to, an electric push rod. In addition, the end of the rack 4024 near the linear drive device 4025 has a... The moving groove (not shown in the figure) has the end of the push rod of the linear drive device 4025 slidably disposed in the moving groove. The moving groove is oriented in the width direction of the base 20, which provides the condition for the rack 4024 to move a predetermined distance along the width direction of the base 20. However, it should be emphasized that when the push rod of the linear drive device 4025 moves along the length direction of the base 20, since the push rod of the linear drive device 4025 extends into the moving groove, it will drive the rack 4024 to move along the length direction of the base 20 in the first sliding groove 40131, and drive each of the first gears 40122 to rotate, and drive the first moving member 4012 to rotate. When the first moving member 4012 rotates, it drives the two contact members 4011 to rotate, and drives the corresponding flange body 10 to rotate.

[0086] Specifically, to ensure that when the first moving member 4012 rotates, the two contact members 4011 rotate accordingly, such as... Figure 7As shown, the second conical surface 40121 of the first moving member 4012 has a plurality of protrusions 40123. Correspondingly, the first conical surface 40111 of each contact member 4011 has a plurality of fourth sliding grooves 40112. The protrusions 40123 correspond one-to-one with the fourth sliding grooves 40112. Each protrusion 40123 is slidably disposed in the corresponding fourth sliding groove 40112. The width of the protrusion 40123 is equal to the groove width of the fourth sliding groove 40112. When the first rotating member rotates, since the protrusions 40123 are placed in the fourth sliding grooves 40112, the two contact members 4011 rotate with it and drive the flange body 10 to rotate.

[0087] However, after the milling device 501 and the grinding device 502 perform cutting on the two straight sides and rough grinding on the bottom surface of the multiple flange bodies 10 arranged in a parallelogram, the flange bodies 10 are still abutting each other and cannot rotate. Therefore, before each flange body 10 rotates synchronously by a predetermined angle, the abutting member 4013 needs to be moved away from one flange body 10, and the remaining flange bodies 10 need to be moved away from each other by a predetermined distance to avoid motion interference between the flange bodies 10 during rotation. The conventional solution is to use multiple driving members to drive each flange body 10 to move away from each other by a predetermined distance in the length direction of the base 20, and to drive the rack 4024 to move a predetermined distance in the width direction of the base 20 by another driving member. Otherwise, because the rack 4024 meshes with the first gear 40122, it is difficult for each flange body 10 to move away from each other.

[0088] In this embodiment, after the milling device 501 and the grinding device 502 perform cutting on the two straight sides and rough grinding on the bottom surface of the plurality of flange bodies 10 arranged in a parallelogram, the abutting member 507 that previously abutted against the flange body 10 moves a predetermined distance away from the flange body 10. Additionally, to ensure that the remaining flanges are moved away from each other by a predetermined distance, such as... Figure 5 and Figure 6As shown, the first moving component 402 further includes a first moving block 4026, a plurality of second moving blocks 4027, and a first lead screw 4028. The first moving block 4026 is fixedly connected to the first lifting drive device 4015 in an inner expansion component 401 located at one end of the parallelogram. The fixed connection method includes, but is not limited to, threaded connection. The first lifting drive devices 4015 in the remaining inner expansion components 401 are all corresponding one-to-one with the second moving blocks 4027 and fixedly installed on the corresponding second moving blocks 4027. Each second moving block 4027 has... The first lead screw 4028 is threadedly connected to the first lead screw 4028, which has several pitch segments (not shown in the figure). Along the direction of the first lead screw 4028 away from the first moving block 4026, the pitch of each pitch segment increases sequentially. Each pitch segment corresponds to one second moving block 4027. In this embodiment, there are four pitch segments, each corresponding to one of the four second moving blocks 4027. A first rotary drive device 4029 is fixedly mounted on the first moving block 4026. The first rotary drive device 4029 is preferably a motor. The first lead screw 4028 is rotatably mounted on... On the first movable block 4026, the first lead screw 4028 is arranged in the length direction of the base 20. A second movable block 4027 is fixedly connected to the push rod of the second lifting drive device 4023 and moves along the height direction of the base 20 with the second lifting drive device 4023. When the first rotary drive device 4029 is activated, the second movable block 4027 moves synchronously on the first lead screw 4028. Since each second movable block 4027 moves on the pitch portion with a different pitch and moves away from the first movable block 4028 along the first lead screw 4028... In the direction of 026, the pitch of each of the screw portions increases sequentially. Therefore, the flange body 10 at the end of the parallelogram closest to the first moving block 4026 is fixed, while the other four flange bodies 10 move different distances in the direction away from the first moving block 4026. This ensures that each flange body 10 is spaced at a predetermined distance, avoiding mutual interference when each flange body 10 rotates. By setting multiple screw portions on the first lead screw 4028, the four flange bodies 10 can be moved by only one first rotary drive device 4029. Compared with the prior art, the number of drive components is less.

[0089] In addition, to solve the interference problem between the first gear 40122 and the rack 4024 when the flange body 10 moves along the first lead screw 4028, such as Figure 6 and Figure 9As shown, the rack 4024 has a release member 40241 at one end near the first moving block 4026. The release member 40241 includes two guide surfaces 402411 and a through groove 402412. The two guide surfaces 402411 are arranged obliquely and located at one end of the through groove 402412 away from the rack 4024. A plurality of elastic members 40132 are provided in the first sliding groove 40131 of the inner expansion assembly 401 located at one end of the parallelogram. The two ends of the elastic members 40132 abut against the groove wall of the first sliding groove 40131 and the rack 4024, respectively. The rack 4024 has a release member 40241 at one end near the first moving block 4012. The flange processing equipment includes several extension blocks 40242, each of which has a second groove 40243 with an opening. The guide assembly 60 abuts against the first moving block 4026. The guide assembly 60 includes a moving frame 601 and a second moving member 602. The moving frame 601 has a third groove 6011, and the second moving member 602 is slidably disposed within the third groove 6011. The second moving member 602 has several guide rods 6021, which are arranged perpendicularly to the second moving member 602. When the second lifting drive device 4023 moves upward a predetermined distance, as... Figure 9 As shown, the guide rod 6021 extends into the corresponding second slide groove 40243, and the first moving block 4026 contacts the moving frame 601. When the first linear module 4022 moves, each of the inner expansion components 401 moves a predetermined distance along the width direction of the base 20, and drives the guide component 60 to move a corresponding distance along the width direction of the base 20. Specifically, as shown... Figure 6 and Figure 9 As shown, the first moving block 4026 moves along the width direction of the base 20 and pushes the moving frame 601 to move synchronously. Furthermore, the flange processing equipment also includes a first slide rod 202, which is fixedly connected to the upright frame 201 by welding. The first slide rod 202 is arranged in the width direction of the base 20. The first moving block 4026 and the moving frame 601 are both slidably disposed on the first slide rod 202. The end of the first slide rod 202 facing away from the upright frame 201 has a blocking part 2021. When each flange body 10 moves between the two milling cutters via the first linear module 4022, the moving frame 601 abuts against the blocking part 2021 under the push of the first moving block 4026. The blocking part 2021 prevents the moving frame 601 from detaching from the first slide rod 202. Additionally, as... Figure 9As shown, the grinding device 502 is provided with a trigger 5021. When the grinding device 502 moves a predetermined distance along the length direction of the base 20, the trigger 5021 contacts or separates from the guide surface 402411 on the release member 40241. More specifically, when the grinding wheel grinds the bottom surface of the four flange bodies 10 below the second moving block 4027 and then grinds the bottom surface of the flange body 10 below the first moving block 4026, the trigger 5021 contacts the guide surface 402411 of the release member 40241 on the rack 4024. Since the guide surface 402411 is an inclined surface, and the guide rod 6021 extends into the rack 4024, the trigger 5021 contacts the guide surface 402411 of the release member 40241. The second groove 40243 on the extension block 40242 of the base 20 provides guidance, and the rack 4024 abuts against the elastic member 40132 and is restricted by the linear drive device 4025. It should be emphasized that since the push rod of the linear drive device 4025 is not moving at this time, the rack 4024 cannot move in the length direction of the base 20. However, since the end of the push rod of the linear drive device 4025 is slidably disposed in the moving groove on the rack 4024, the rack 4024 can move in the width direction of the base 20. When the trigger 5021 contacts the guide surface 402411, the trigger 5021 moves along the guide surface 402411. The rack 4024 moves a predetermined distance along the width direction of the base 20. At this time, the elastic element 40132 compresses a predetermined distance, and at a certain moment, the rack 4024 separates from each of the first gears 40122. After the rack 4024 separates from each of the first gears 40122, the shaft of the first rotary drive device 4029 moves, causing the four flange bodies 10 with ground bottom surfaces to move along the first lead screw 4028 and be spaced a predetermined distance apart. When the trigger 5021 moves a further predetermined distance along the guide surface 402411, the trigger 5021 extends into the through groove 402412 on the release member 40241. When the trigger 5021 penetrates... After passing through the through groove 402412, since the trigger 5021 is no longer under force, the rack 4024 connected to the trigger 5021 resets under the elastic force of the elastic member 40132 and meshes with the corresponding first gear 40122. It should be emphasized that at this time, each flange body 10 is spaced apart by a predetermined distance. After the bottom surface of each flange body 10 has been rough-machined and ground, the linear drive device 4025 is activated, driving the rack 4024 to move along the length direction of the base 20. Since the rack 4024 meshes with each first gear 40122, each first moving member 4012 and each flange body 10 rotate synchronously by a predetermined angle. Subsequently,The first rotary drive device 4029 operates, causing each flange body 10 to move along the width direction of the base 20 and abut against each other, reassembling into another parallelogram and exposing the two straight sides to be processed. At this time, the contact member 507 near the second rotary motor 506 abuts against one of the flange bodies 10 at the end under the action of the external drive element. Subsequently, the second rotary motor 506 operates, causing the grinding device 502 located at the end to contact the bottom surface of the flange body 10 first and perform finishing on the bottom surface of the flange body 10. The milling cutter on the milling device 501 then performs finishing on the two sides of the flange body 10 to be processed after the grinding device 502. The cutting is performed on the straight side surfaces. It should be noted that during the movement of the grinding device 502, the trigger 5021 will again contact the release member 40241, causing the rack 4024 to move away from the corresponding first gear 40122, until the trigger 5021 passes through the through groove 402412. It should be pointed out that during this process, the shaft of the first rotary drive device 4029 does not move, and each flange body 10 still abuts against each other and forms a parallelogram. Thus, the straight side surfaces of multiple flange bodies 10 are cut, and the bottom surfaces of multiple flange bodies 10 are rough and finish ground, completing step S1 of the above-described flange processing method.

[0090] Additionally, when the first moving member 4012 rotates, to reduce wear between the abutment member 4013 and the contact member 4011, such as... Figure 7 As shown, each of the abutment members 4013 has several balls 40133 rolled on both ends, and the side of the first gear 40122 facing away from the first lifting drive device 4015 contacts the balls 40133.

[0091] In addition, to improve the motion stability of the first linear module 4022, such as Figure 8 As shown, the flange processing equipment further includes a mounting base 203 and a second slide rod 204. The second slide rod 204 is located at the end of the upright 201 opposite to the first slide rod 202. The first linear module 4022 is located between the first slide rod 202 and the second slide rod 204. The second slide rod 204 is arranged parallel to the first slide rod 202. The mounting base 203 is slidably disposed on the second slide rod 204. The end of the first lead screw 4028 opposite to the first moving block 4026 is rotatably mounted on the mounting base 203.

[0092] Furthermore, such as Figure 8As shown, the flange processing equipment also includes a feeding device 70, which is located below the grinding device 502. The feeding device 70 includes a feeding support 701, a third lifting drive device 702, a second linear module 703, a support frame 704, and a longitudinal drive device 705. The top surface of the feeding support 701 has two spaced-apart inserts 7011. The side of the feeding support 701 facing away from the inserts 7011 is fixedly connected to the push rod of the third lifting drive device 702. The fixed connection method includes, but is not limited to, threaded connection. The third lifting drive device 702 is located on the second linear module 703 and moves with the second linear module 703 along the length direction of the base 20. The second linear module 703 is fixedly mounted on the support frame 704. The support 704 is mounted on the longitudinal drive device 705 and moves along with the longitudinal drive device 705 in the width direction of the base 20. After all four straight sides of a flange body 10 are cut, the unloading device 70 is activated, and the insert rod 7011 is inserted into the two second connecting holes 104 of the corresponding flange body 10, and the flange body 10 abuts against the top surface of the unloading support 701 or another flange body 10. Subsequently, the corresponding inner expansion component 401 releases the flange body 10, realizing the unloading of this flange body 10. The unloading device 70 repeats the above actions several times, and finally places multiple flange bodies 10 arranged in a stack on the unloading support 701 and sends them to the subsequent work station, providing the prerequisite preparation for step S2 of the above-mentioned flange processing method.

[0093] In summary, the flange, its processing method, and processing equipment described in the embodiments of this application have been clarified, which provide the flange with the advantage of being less prone to fluid leakage, and provide the flange processing method and processing equipment with advantages such as improving production efficiency.
