Description

Technical Field

[0001] This invention relates to the field of grinding equipment technology, specifically to a grinding device for the end face of a segmented flange. Background Technology

[0002] A segmented flange is a special design that divides a flange into multiple segmented parts, which are then assembled into a complete flange using connectors. It is mainly used to solve the transportation and installation problems of large-diameter flanges. The typical feature of this type of flange is that the originally integral flange is split into multiple arc-shaped parts, which are connected laterally by segmented connecting bolts and longitudinally fixed using segmented connecting devices and flange connecting bolts. Its structure includes components such as flange horizontal plates, necks, and vertical plates. Some designs also have limit bosses or arc-shaped plate slots to ensure stability and sealing after assembly.

[0003] The splicing accuracy and sealing performance of segmented flanges directly depend on the processing quality of the flange plates, among which the grinding effect of the two end faces and the mating surface of the flange plates is crucial. The two end faces must be flat and smooth to meet the sealing requirements, and the mating surface must be tightly fitted to ensure the structural strength after splicing. Therefore, the multi-face grinding process is a key step in the processing of segmented flanges.

[0004] However, existing grinding equipment has significant drawbacks: First, grinding efficiency is low. Existing devices can typically only grind single flanges one by one, making batch processing impossible and difficult to adapt to the needs of industrial production. Second, positioning stability is poor. There is a lack of a universal clamping structure for curved flanges of different sizes, which can easily lead to displacement during grinding, resulting in insufficient grinding accuracy. Third, angle adjustment is inconvenient. The end face of the flange is curved, and the grinding path needs to consider the adjustment requirements of different heights. Moreover, the flange is relatively long, requiring moving grinding. Existing technology makes it difficult to adjust the grinding path for flanges of different sizes. Fourth, multi-face grinding coordination is poor. The end face and the mating surface need to be ground separately on different equipment or at different workstations, making the process connection cumbersome and further reducing production efficiency. Summary of the Invention

The end of the push rod is provided with a threaded platform that mates with the threaded holes at both ends of the placement box. The push rod is located in the groove of the U-shaped clamping plate. The push rod is provided with a push block that abuts against the U-shaped clamping plate.

[0008] As an improvement: the fixed platform is provided with an adjusting wing plate, which is located on both sides of the push plate and bolted to the fixed platform. The adjusting wing plate is slidably provided with a second push plate, and the second push plate has a insertion platform on its side. One side of the push plate has a slot that engages with the insertion platform.

[0009] As an improvement: the adjustment mechanism includes a support frame and a hydraulic cylinder. The two support frames are symmetrically arranged on both sides of the adjustment platform. Both ends of the adjustment platform are provided with turntables that rotate with the support frames. A vertical rod is provided on the outside of the adjustment platform.

[0010] As an improvement: the bottom of the adjustment platform is provided with an arc-shaped platform, the center of which coincides with the center of the turntable, and a support roller is provided between the two support frames for rotation, the support roller cooperating with the arc-shaped platform.

[0011] As an improvement: the fixed frame is equipped with a motor, and a threaded column is rotatably provided on the inner side of the top beam of the fixed frame. The motor is connected to the threaded column for transmission. The two ends of the movable frame are provided with drive slides that slide in cooperation with the grooves of the top beam of the fixed frame. The drive slides are provided with threaded holes that cooperate with the threaded column.

[0012] As an improvement: the movable frame is equipped with a second motor that is connected to the drive shaft. One end of the drive shaft is equipped with a spline shaft.

By integrating clamping, angle adjustment, and double-end and mating surface grinding mechanisms, it achieves precise, efficient, and batch processing of flanges, significantly improving grinding quality and production efficiency, and reducing manufacturing costs. Specifically: 1. Strong batch clamping adaptability: The clamping mechanism is designed to be compatible with flanges of different sizes through the linkage of the adjusting wing plate and the push plate. The four-point positioning and the group storage of the placement box ensure that the batch flanges are positioned stably and arranged neatly, avoiding displacement during grinding. 2. Precise and stable angle adjustment: The adjustment mechanism is driven by a hydraulic cylinder and works in conjunction with the support roller of the arc-shaped table to achieve flexible angle adjustment of the adjustment table, changing the existing grinding path. By adjusting the posture of the flange, the grinding wheel only needs to move laterally to grind the arc surface, simplifying the adjustment process and adapting to different size grinding needs. 3. Highly efficient and collaborative multi-face grinding: The double-sided grinding wheel and multi-wheel linkage design of the end face grinding mechanism and the grinding belt support structure of the mating face grinding mechanism enable simultaneous and precise grinding of both end faces and mating surfaces, eliminating the need to change workstations and simplifying the process. 4. Precise and controllable transmission and feed: gear-threaded column transmission, spline shaft fit and hydraulic cylinder drive ensure precise front-to-back and axial movement of the grinding wheel, adjustable grinding belt fit, and greatly improved grinding uniformity and precision.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] Combined with appendix Figure 1 and attached Figure 3As shown, a segmented flange end face grinding device includes an end face grinding mechanism 5, which includes a fixed frame 51, a movable frame 52, and a grinding wheel 53. The grinding wheel 53 is mounted on the movable frame 52, which is movably mounted on the fixed frame 51. The grinding wheel 53 grinds the two end faces 101 of the flange 100. The device also includes a clamping mechanism 1, a placement box 2, an adjusting platform 3, an adjusting mechanism 4, and a mating surface grinding mechanism 6. After the flange 100 is clamped and positioned by the clamping mechanism 1, it is placed in a row in the placement box 2. The placement box 2 is hoisted on the adjusting platform 3. The adjusting mechanism 4 adjusts the angle of the adjusting platform 3. The mating surface grinding mechanism 6 is symmetrically arranged on both sides of the adjusting platform 3 and grinds the mating surfaces 102 of the flange 100.

[0031] To address the issues of unstable positioning, difficulty in angle adjustment, and low efficiency caused by the need to process the two end faces 101 and the mating surface 102 separately during the grinding of segmented flanges, a clamping mechanism 1 is used to achieve precise positioning of the flange pieces 100. A storage box 2 is used to store the flange pieces in groups for easy batch processing. An adjustment mechanism 4 is used to adjust the angle of the adjustment table 3 to adapt to the grinding requirements. The end face 101 and mating surface 102 grinding mechanisms grind the two end faces 101 and the mating surface 102 respectively, effectively solving the problems of positioning deviation, angle limitation, and low efficiency of multi-face grinding.

[0032] Before grinding, the flange 100 is placed on the clamping mechanism 1. Then, multiple clamping mechanisms 1 carrying flange 100 are placed in a row into the placement box 2. The clamping mechanism 1, together with the placement box 2, clamps and fixes the flange 100, ensuring that the flange 100 is neatly arranged and stable without shaking, thus completing the sorting and storage of batches of parts to be ground. The placement box 2 is then hoisted onto the adjustment table 3, so that the flange 100 is in the position to be ground. According to the grinding angle requirements of the two end faces 101 and the mating face 102 of the flange 100, the adjustment mechanism 4 is activated to adjust the angle of the adjustment table 3.

[0033] After adjustment, start the end face grinding mechanism 5. The movable frame 52 moves on the fixed frame 51, driving the grinding wheel 53 to approach the end faces 101 on both sides of the flange 100. During grinding, the movable frame 52 needs to drive the grinding wheel 53 to move back and forth, while cooperating with the adjustment mechanism 4 to adjust the angle of the adjustment table 3 to grind the end faces 101 on both sides of the long strip flange 100. When grinding the mating surface 102, the adjustment mechanism 4 adjusts the angle of the mating surface 102 of the flange 100 to make it parallel to the grinding surface of the mating surface grinding mechanism 6. Then the mating surface grinding mechanism 6 starts to grind the mating surface 102 of the flange 100. After all surfaces are ground, turn off each grinding mechanism, remove the placement box 2 from the adjustment table 3, release the clamping mechanism 1, and take out the ground flange 100.

[0034] Combined with appendix Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 6 As shown, the clamping mechanism 1 includes a fixed platform 11 and a push plate 12. The fixed platform 11 is bolted to the placement box 2. The fixed platform 11 has a sliding cavity 111 on its inner side. The sliding cavity 111 has a sliding rod 112 inside it. The push plate 12 is located inside the sliding cavity 111. The fixed platform 11 and the push plate 12 are placed in the groove on the outer side of the flange 100 and clamp the flange 100 internally. The sliding rod 112 slides with the through hole on the push plate 12. The bottom of the push plate 12 has a U-shaped clamping plate 121 extending out of the bottom through hole of the fixed platform 11. The placement box 2 has a push rod 21 inside it. The end of the push rod 21 has a threaded platform 22 that mates with the threaded holes at both ends of the placement box 2. The groove of the U-shaped clamping plate 121 is locked on the push rod 21. The push rod 21 has a push block 23 that abuts against the U-shaped clamping plate 121.

[0035] Combined with appendix Figure 4 and attached Figure 5 As shown, the top of the fixed platform 11 is provided with a top platform 113, and the fixed platform 11 is provided with an adjusting wing plate 13. The adjusting wing plate 13 is provided on both sides of the push plate 12. The top of the top platform 113 and the top of the adjusting wing plate 13 are in contact with the flange plate 100. One side of the adjusting wing plate 13 is provided with a side platform 131, and one side of the fixed platform 11 is provided with a slot 114. The through hole on the side platform 131 is connected to the slot 114 by bolts. The second push plate 14 is slidably provided in the adjusting wing plate 13. The side of the second push plate 14 is provided with a insertion platform 141, and the side of the first push plate 12 is provided with a slot 122 that is inserted and engaged with the insertion platform 141.

[0036] To address the issues of poor compatibility, unstable clamping, and insufficient adjustment flexibility of flange plates 100 of different sizes, the bolt connection between the wing plate 13 and the slot 114 is adjusted to change the height of the top of the wing plate 13. Four-point positioning is used to adapt to the flange size. The insertion platform 141 and slot 122 of the push plate 12 and the push plate 24 cooperate to enhance the stability of the linkage clamping. The push rod 21 cooperates with the U-shaped clamping plate to provide clamping power. The fixed platform 11 and the placement box 2 are bolted together to ensure overall stability. This effectively solves the problems of poor compatibility, unstable clamping, and inconvenient adjustment.

[0037] According to the size of the flange 100 to be clamped, adjust the position of the two side adjusting wing plates 13: loosen the bolts connecting the side platform 131 to the slot 114 of the fixed platform 11, move the adjusting wing plate 13 to a suitable height so that the top platform 113 and the top of the adjusting wing plate 13 can fit against the two sides of the flange 100, then tighten the bolts to fix the adjusting wing plate 13. Then place the clamping mechanism 1 carrying the flange 100 in a row in the placement box 2, and fix the fixed platform 11 to the placement box 2 with bolts to ensure that the overall installation is stable. The clamping mechanism 1 uses four-point positioning to make the centers of multiple flanges 100 on the same horizontal line. Then align the mating surfaces 102 of the flanges 100.

[0038] After adjustment, fix the flange 100 in place, twist the threaded table 22 to screw it into the threaded holes at both ends of the placement box 2. The push block 23 on the push rod 21 moves with the push rod 21, pushing the U-shaped clamping plate 121 to move axially (the groove of the U-shaped clamping plate 121 is locked on the push rod 21), which drives the push plate 12 to slide along the slide rod 112 in the slide cavity 111 of the fixed table 11. When the push plate 12 slides, the push plate 24 slides synchronously through the cooperation of the insertion table 141 and the slot 122. The push plate 12, the push plate 24, the top table 113, and the adjusting wing plate 13 work together to provide external support and fixation from the groove on the outside of the flange 100. If it is necessary to loosen the flange 100, rotate the push rod 21 in the opposite direction, the push block 23 disengages from the U-shaped clamping plate 121, the push plate 12 and the push plate 24 reset, and the flange 100 can be removed.

[0039] Combined with appendix Figure 2 Appendix Figure 7 and attached Figure 8 As shown, the adjustment mechanism 4 includes a support frame 41 and a hydraulic cylinder 42. The two support frames 41 are symmetrically arranged on both sides of the adjustment platform 3. Both ends of the adjustment platform 3 are provided with turntables 33 that rotate with the support frames 41. A vertical rod 32 is provided on the outer side of the adjustment platform 3. The bottom of the hydraulic cylinder 42 is hinged to the floor and the output end of the hydraulic cylinder 42 is hinged to the vertical rod 32. An arc-shaped platform 34 is provided at the bottom of the adjustment platform 3. The center of the arc-shaped platform 34 coincides with the center of the turntable 33. A support roller 43 is rotatably arranged between the two support frames 41. The support roller 43 cooperates with the arc-shaped platform 34. A positioning platform 31 is provided in the groove at the top of the adjustment platform 3. The groove at the bottom of the placement box 2 is engaged with the positioning platform 31.

[0040] To address the issues of inaccurate angle adjustment of the adjustment platform 3, insufficient support stability, and easy displacement of the placement box 2, the angle of the adjustment platform 3 is flexibly adjusted by rotating the turntable 33 and the support frame 41, and driving the upright 32 with the hydraulic cylinder 42. The arc-shaped platform 34 and the support roller 43 work together to enhance support stability, and the positioning platform 31 is engaged with the placement box 2 to ensure accurate positioning. This effectively solves the problems of adjustment deviation, unstable support, and displacement of the placement box 2.

[0041] Two support frames 41 are symmetrically fixed on the floor. The turntables 33 at both ends of the adjustment platform 3 are rotatably connected to the support frames 41, so that the adjustment platform 3 can rotate around the center of the turntable 33. At the same time, the bottom of the hydraulic cylinder 42 is hinged to the floor, and the output end is hinged to the upright 32 on the outside of the adjustment platform 3. The support roller 43 between the two support frames 41 is rotatably installed and fits against the arc-shaped platform 34 at the bottom of the adjustment platform 3 (the center of which coincides with the center of the turntable 33).

[0042] When the placement box 2 for the flange plate 100 is hoisted to the adjustment platform 3, the bottom groove of the placement box 2 is engaged with the positioning platform 31 in the top groove of the adjustment platform 3 to prevent the placement box 2 from shifting during adjustment. When the angle needs to be adjusted, the hydraulic cylinder 42 is activated, and its output end extends and retracts to drive the upright 32, thereby pushing the adjustment platform 3 to rotate around the turntable 33. At this time, the arc-shaped platform 34 rotates synchronously with the adjustment platform 3, and the support roller 43 always rolls in contact with the arc-shaped platform 34 to provide stable support for the adjustment platform 3 and avoid swaying during angle adjustment. After the adjustment platform 3 is adjusted to a suitable angle according to the grinding requirements, the hydraulic cylinder 42 is closed. The adjustment platform 3 maintains a stable angle under the locking force of the hydraulic cylinder 42 and the support roller 43, ensuring that the subsequent grinding operation is carried out accurately. After grinding is completed, the hydraulic cylinder 42 extends and retracts in the opposite direction to drive the adjustment platform 3 to reset, and the placement box 2 can be removed.

[0043] Combined with appendix Figure 9 and attached Figure 10 As shown, the fixed frame 51 is equipped with a motor 511, and a threaded column 512 is rotatably provided on the inner side of the top beam of the fixed frame 51. The output end of the motor 511 is equipped with a gear 513. One end of the threaded column 512 is equipped with a gear 514 that meshes with the gear 513. The movable frame 52 is equipped with drive slides 521 at both ends that slide in the groove of the top beam of the fixed frame 51. The drive slides 521 are equipped with threaded holes that mate with the threaded column 512. The movable frame 52 drives the grinding wheel 53 to move back and forth along the gap direction of the flange 100.

[0044] Combined with appendix Figure 10 and attached Figure 11 As shown, the grinding wheel 53 is a double-sided grinding wheel, and multiple grinding wheels 53 are arranged at intervals and connected by a drive shaft 531. The movable frame 52 is equipped with a second motor 54 that is connected to the drive shaft 531. The bottom of both ends of the fixed frame 51 is slidably equipped with a hanger 57. The bottom of the hanger 57 is rotatably connected to the end of the drive shaft 531, and the hanger 57 drives the drive shaft 531 to move axially. The fixed frame 51 is equipped with a second hydraulic cylinder 56, and the output end of the second hydraulic cylinder 56 is connected to the top extension end of one of the hangers 57.

[0045] Combined with appendix Figure 10 and attached Figure 11 As shown, one end of the drive shaft 531 is provided with a spline shaft 532, and the bottom of the fixed frame 51 is provided with a rotatable sprocket 55. The inner side of the sprocket 55 is provided with a spline groove that cooperates with the spline shaft 532. The output end of the motor 54 is provided with a sprocket 541 that is in drive cooperation with the sprocket 55.

[0046] To address the issues of inaccurate forward and backward movement of the grinding wheel 53, inconvenient axial position adjustment, unstable transmission, and low grinding efficiency of the two end faces 101, the grinding wheel 53 is precisely moved forward and backward through gear and threaded column 512 transmission. The spline shaft 532 and spline groove cooperate to ensure stable transmission when the drive shaft 531 moves axially. The hydraulic cylinder 56 drives the hanger 57 to achieve flexible axial adjustment of the grinding wheel 53. The double-sided grinding wheel and the multiple wheels arranged at intervals improve the synchronous grinding efficiency and uniformity of the two end faces 101, effectively solving the above problems.

[0047] During operation, start motor 511. Gear 513 at its output end drives gear 514 at one end of threaded column 512 to rotate, causing threaded column 512 to rotate inside the top beam of fixed frame 51. Threaded column 512 engages with threaded holes on drive slides 521 at both ends of movable frame 52, driving slides 521 to slide along the groove of the top beam of fixed frame 51. This drives movable frame 52 and grinding wheel 53 to move back and forth along the gap direction of flange 100, adjusting the grinding position.

[0048] Simultaneously, motor 2 54 starts, and its output sprocket 1 541 drives sprocket 2 55 at the bottom of the fixed frame 51 to rotate. The spline groove on the inner side of sprocket 2 55 cooperates with the spline shaft 532 at one end of the drive shaft 531 to transmit power to the drive shaft 531, causing multiple grinding wheels 53 arranged at intervals to rotate synchronously (grinding wheels 53 are double-sided grinding wheels, which can grind the two end faces 101 of the flange 100). When grinding the end face 101 of another flange 100, hydraulic cylinder 2 56 is started, and its output end pushes the hanger 57 connected to it (the bottom of the hanger 57 is rotatably connected to the end of the drive shaft 531) to slide along the bottom of the fixed frame 51, driving the drive shaft 531 to move axially. The spline shaft 532 slides in the spline groove to ensure that the transmission is not interrupted until the grinding wheel 53 contacts the end face 101 of the other flange 100.

[0049] During the grinding process, the movable frame 52 drives the grinding wheel 53 to move back and forth continuously, and the angle of the flange 100 is adjusted in conjunction with the adjustment mechanism 4. The double-sided grinding wheel 53 grinds the two end faces 101 of the flange 100 evenly. After the grinding is completed, the motor 1 511 and the motor 2 54 stop, the hydraulic cylinder 2 56 drives the hanger 57 to reset, and the movable frame 52 returns to the initial position, completing the operation.

[0050] Combined with appendix Figure 12 and attached Figure 13As shown, the mating surface grinding mechanism 6 includes a support platform 61, a movable platform 62, a grinding belt 63, a hydraulic cylinder 64, a motor 65, and rotating rollers 66. The hydraulic cylinder 64 drives the movable platform 62 to move back and forth on the support platform 61. Two rotating rollers 66 are rotatably located at both ends of the movable platform 62. The output end of the motor 65 is provided with a pulley 651. One of the rotating rollers 66 is provided with a pulley 661 connected to the pulley 651 via a belt drive. The grinding belt 63 is wound around the two rotating rollers 66. The inner side of the movable platform 62 is provided with a top plate 621 that cooperates with the inner side of the grinding belt 63.

[0051] To address the issues of poor fit, inconvenient feed adjustment, and insufficient grinding efficiency of the flange 100 mating surface 102, a hydraulic cylinder 64 drives the movable table 62 to achieve precise feed. The top plate 621 supports the grinding belt 63 to ensure a tight fit with the mating surface 102. The motor 65 drives the grinding belt 63 in a cyclical transmission, effectively solving the problems of poor fit, imprecise adjustment, and low grinding efficiency.

[0052] Before operation, the support platform 61 of the mating surface grinding mechanism 6 is symmetrically fixed on both sides of the adjustment platform 3 to ensure that the moving direction of the movable platform 62 is perpendicular to the mating surface 102 of the flange 100. The movable platform 62 is installed on the support platform 61, and two rotating rollers 66 are respectively rotatably located at both ends of the movable platform 62. The grinding belt 63 is wound around the outside of the two rotating rollers 66. The top plate 621 on the inner side of the movable platform 62 is tightly fitted with the inner side of the grinding belt 63 to provide support for the grinding belt 63. The motor 65 is fixed on the movable platform 62, and the belt drive structure of the motor 65 drives the grinding belt 63 to rotate and grind the mating surface 102.

[0053] When the adjusting table 3 is adjusted to a suitable angle by the adjusting mechanism 4, and the mating surface 102 of the flange 100 is parallel to the grinding belt 63, the hydraulic cylinder 64 is activated. Its output end pushes the movable table 62 along the support table 61 towards the flange 100 until the grinding belt 63 is tightly fitted with the mating surface 102. The top plate 621 always supports the grinding belt 63 to prevent deformation of the grinding belt during grinding from affecting the grinding accuracy. Then, the motor 65 is activated, and its output end drives the pulley 651 to rotate. Through the pulley 651 and pulley 652, the grinding belt rotates. Driven by 661, the rotating roller 66 connected to the second pulley 661 rotates. The rotating roller 66 drives the grinding belt 63 to circulate between the two rotating rollers 66, uniformly grinding the mating surface 102 of the flange 100. During the grinding process, if it is necessary to adjust the grinding feed, the hydraulic cylinder 64 can finely adjust the position of the movable table 62 to ensure that the mating surface 102 is ground flat. After the grinding is completed, the motor 65 stops running, the hydraulic cylinder 64 drives the movable table 62 to move in the opposite direction and reset, and the grinding belt 63 stops moving, completing the mating surface grinding operation.
