[0021] Terms such as "first", "second", "third", etc. are only used to distinguish elements with similar attributes, rather than indicating or implying relative importance or a specific order.

[0022] The term "comprising", "including" or any other variation thereof is intended to cover non-exclusive inclusion, in addition to the elements listed, and may also include other elements not expressly listed.

[0023] As Figure 1 shown, the flange processing system proposed by the present invention is used to grind the end face of the first flange 101 to process the second flange 102 with a flat end face, and then weld bolts 100 into the bolt holes of the second flange 102 to process the third flange 103.

[0024] Combined Figure 1 with Figure 2 , the flange processing system proposed by the present invention includes: a feeding mechanism 10 for conveying the first flange 101, a grinding mechanism 20 for grinding the end face of the first flange 101 from the feeding mechanism 10 to process the second flange 102, a turnover mechanism 30 for conveying the second flange 102 from the grinding mechanism 20, a welding mechanism 40 for welding bolts 100 into the bolt holes of the second flange 102 to process the third flange 103, a detection mechanism 50 for detecting whether the bolts 100 of the third flange 103 are welded in place.

[0025] The setting of the feeding mechanism 10 can realize the feeding of the first flange 101 to be ground, so as to feed the first flange 101 to the grinding mechanism 20; the grinding mechanism 20 can grind the end face of the first flange 101 to ensure that the second flange 102 has good end face flatness; the turnover mechanism 30 can convey the second flange 102 to the welding mechanism 40 to ensure the continuity of production; the welding mechanism 40 can weld bolts 100 into the bolt holes of the second flange 102 to facilitate the subsequent use of the third flange 103; the detection mechanism 50 can detect the position of the bolts 100 on the third flange 103 to ensure the passing rate of the third flange 103 at the factory. The whole processing system has good production continuity, high automation, can improve the processing efficiency of the flange and ensure the passing rate.

[0026] In an exemplary solution, as Figure 3 shown, the grinding mechanism 20 includes a turntable 21 and a grinding member 22. The turntable 21 is arranged on one side of the feeding mechanism 10. A positioning groove 23 is formed on the turntable 21. The positioning groove 23 is used to accommodate the first flange 101 and the second flange 102. The turntable 21 is configured to be able to rotate around its own central axis (as Figure 3in the direction indicated by the arrow in the figure), to change the position of the positioning groove 23 relative to the feeding mechanism 10 and the grinding member 22. The feeding mechanism 10 is used to send the first flange 101 to be ground into the positioning groove 23. The grinding member 22 is arranged on at least one side of the turntable 21, and the grinding member 22 is configured to be able to contact the end face of the first flange 101 in the positioning groove 23 for end face grinding.

[0027] By rotating the turntable 21, the position of the positioning groove 23 relative to the feeding mechanism 10 and the grinding member 22 can be changed, thereby realizing the change of the feeding station and the grinding station of the first flange 101. By rotating the angle of the turntable 21, the position of the first flange 101 can be switched, so that the second flange 102 after grinding is away from the grinding member 22, and the first flange 101 fed by the feeding mechanism 10 can cooperate with the grinding member 22 for grinding. The production continuity is strong, the production cost is reduced, and it is beneficial to improve the grinding efficiency.

[0028] During the rotation of the turntable 21, the first flange 101 and the second flange 102 in the positioning groove 23 will not be disengaged from the positioning groove 23 along the axial direction of the turntable 21 under the action of centripetal force. And only by applying a force along the axial direction of the turntable 21 to the second flange 102 in the positioning groove 23, the unloading of the second flange 102 can be realized. Compared with the prior art, after grinding once, it is necessary to stop the machine for a long time, and then continue to start the machine for grinding after changing the material, which reduces the number of stops and the duration of the stop of the grinding member 22. The production continuity is strong, the automation degree is high, and the grinding efficiency is high.

[0029] Exemplarily, the positioning groove 23 is axially opened on the turntable 21 and is circumferentially distributed on the turntable 21, so as to facilitate adjusting the position of the positioning groove 23 by rotating the angle of the turntable 21.

[0030] Exemplarily, the thickness of the positioning groove 23 is configured to be less than or equal to the vertical distance between the two end faces of the first flange 101, so that when the first flange 101 is located in the positioning groove 23, its end face can contact the grinding member 22 and be ground. Preferably, the thickness of the positioning groove 23 is less than the vertical distance between the two end faces of the first flange 101.

[0031] In an exemplary solution, referring to Figure 2 , the turnover mechanism 30 includes a discharging part and a conveying member 31. The discharging part is arranged on one side of the turntable 21 and can apply a force along the axial direction of the turntable 21 to the second flange 102 in the positioning groove 23 to take out the second flange 102 from the positioning groove 23 to realize discharging. The conveying member 31 is used to convey the second flange 102 to the welding mechanism 40.

[0032] Exemplarily, in combination with Figure 2 and Figure 3, the turnover mechanism 30 further includes a blanking guide 32. The blanking guide 32 is installed at the upper end of the conveying member 31, and the position of the blanking guide 32 corresponds to the position of the blanking mechanism. The upper end of the blanking guide 32 extends to the lower side of the positioning groove 23 that cooperates with the blanking mechanism to receive the second flange 102 taken out from the positioning groove 23 and guide the second flange 102 to the conveying member 31.

[0033] When the positioning groove 23 containing the second flange 102 rotates to the blanking mechanism, the blanking mechanism can apply a force to the second flange 102 to cause the second flange 102 to fall from the positioning groove 23 onto the blanking guide 32 and fall onto the conveying member 31 through the guidance of the blanking guide 32. During the blanking process, neither the turntable 21 nor the grinding member 22 needs to stop, ensuring good production continuity.

[0034] Optionally, the blanking guide 32 is made of a plate member and is inclinedly installed on one side of the conveying member 31.

[0035] Optionally, the conveying member 31 is a conveyor belt.

[0036] In an exemplary solution, as Figure 3 shown, the grinding mechanism 20 includes two grinding members 22. The two grinding members 22 are arranged on both axial sides of the turntable 21. The two grinding members 22 can simultaneously grind the two end faces of the first flange 101 accommodated in the positioning groove 23. Compared with grinding only one end face at a time, the time required for grinding can be shortened, which is beneficial to improving the grinding efficiency.

[0037] Exemplarily, the two grinding members 22 are configured to be able to move synchronously along the axial direction of the turntable 21 to change the distance between the two grinding members 22 and adjust the position of the first flange 101 accommodated in the positioning groove 23. When the two grinding members 22 approach each other and can both contact the end faces of the first flange 101, the two end faces of the first flange 101 can be simultaneously ground.

[0038] In an exemplary solution, as Figure 3 shown, the feeding mechanism 10 includes a support portion 110 and a pushing portion 120. The support portion 110 is used to place the first flange 101 to be ground, and the pushing portion 120 is used to feed the first flange 101 from the support portion 110 to the grinding mechanism 20. More specifically, the pushing portion 120 is used to feed the first flange 101 into the positioning groove 23.

[0039] Exemplarily, combining Figure 4 and Figure 5, the support part 110 includes a supporting member 11 and a limiting member 12. The supporting member 11 is installed on one side of the turntable 21, the first flange 101 can be placed on the supporting member 11, the limiting member 12 is installed at the upper end of the supporting member 11 close to the turntable 21, and a feeding groove 121 is formed on the limiting member 12. The feeding groove 121 penetrates through the limiting member 12 along the axial direction of the turntable 21 and matches the end face contour of the first flange 101.

[0040] When the turntable 21 rotates to a position where the positioning groove 23 corresponds to the feeding groove 121, the pushing part 120 works to push the first flange 101 closest to the turntable 21 placed on the supporting member 11 into the positioning groove 23, thereby realizing the feeding of the first flange 101.

[0041] Optionally, a receiving groove matching the lower contour of the first flange 101 is formed on the supporting member 11 for receiving the first flange 101.

[0042] Optionally, as Figure 5 shown, the supporting member 11 is a plate member, two supporting members 11 are inclined, and the distance between the two supporting members 11 gradually decreases from top to bottom, so that the two supporting members 11 are distributed in a V shape, for contacting the lower end of the first flange 101 and being able to provide good support for the first flange 101, and can be applicable to different shapes of the first flange 101, such as circular flanges, diamond flanges, square flanges, etc., with good applicability.

[0043] Exemplarily, in combination with Figure 5 and Figure 6 , at least one mounting seat 13 is connected to the lower end of the supporting member 11. An installation shaft 111 protrudes from the lower end of the supporting member 11. The mounting seat 13 includes a first clamping arm 131, a second clamping arm 132 and a locking member 133. The first clamping arm 131 and the second clamping arm 132 cooperate to form a shaft hole 134. The installation shaft 111 passes through the shaft hole 134, and the locking member 133 is used to adjust the distance between the first clamping arm 131 and the second clamping arm 132 to change the size of the shaft hole 134, so as to fix the installation shaft 111 in the shaft hole 134.

[0044] Optionally, the installation shaft 111 is integrally formed with the supporting member 11 or connected as a whole by means of gluing, welding, etc.

[0045] Optionally, screw holes matching the locking member 133 are formed on both the first clamping arm 131 and the second clamping arm 132. The locking member 133 includes a threaded member that can be screwed into the screw holes. The distance between the first clamping arm 131 and the second clamping arm 132 can be adjusted by screwing, and then the installation of the supporting member 11 is realized through the installation shaft 111.

[0046] Optionally, the number of the mounting seats 13 is set to two, and the two mounting seats 13 are arranged on both sides of the mounting shaft 111 along the axial direction to fix both ends of the mounting shaft 111.

[0047] Exemplarily, in combination with Figure 5 and Figure 6 , a supporting seat 14 is further connected to the lower end of the supporting member 11. A supporting groove 141 matching with the mounting shaft 111 is formed at the upper end of the supporting seat 14, and the lower part of the mounting shaft 111 is received in the supporting groove 141.

[0048] The arrangement of the supporting seat 14 can not only cooperate with the mounting seat 13 to fix and support the supporting member 11, but also ensure the stability of the installation of the supporting member 11 when the supporting member 11 is relatively long, avoiding the shaking and position deviation of the first flange 101 thereon due to the instability of the supporting member 11. By arranging the supporting seat 14, compared with arranging multiple mounting seats 13, the structure is simpler, the disassembly and assembly can be completed without multiple adjustments, and the input cost is reduced.

[0049] Optionally, the supporting seat 14 is arranged between the two mounting seats 13 for supporting the middle part of the mounting shaft 111.

[0050] In an exemplary solution, as Figure 6 shown, the material pushing part 120 includes a first driving member 15 and a push rod 16. The output shaft of the first driving member 15 is connected to one end of the push rod 16 for driving the push rod 16 to move along the axial direction of the turntable 21. The end of the push rod 16 away from the first driving member 15 can contact with the first flange 101 on the supporting member 11 to feed the first flange 101 into the positioning groove 23.

[0051] Exemplarily, as Figure 6 shown, a connecting plate 151 is installed on the output shaft of the first driving member 15, and the connecting plate 151 is detachably connected to at least one push rod 16 to adjust the position and quantity of the push rod 16 according to the specification of the first flange 101.

[0052] Optionally, the first driving member 15 adopts a cylinder.

[0053] Exemplarily, the aforementioned unloading mechanism can also refer to the setting of the material pushing part 120. The unloading mechanism includes a first driving member 15 and a push rod 16, so as to apply a force along the axial direction of the turntable 21 to the first flange 101 in the positioning groove 23 through the first driving member 15 to push the first flange 101 out of the positioning groove 23 and make it fall on the conveying member 31.

[0054] In an exemplary solution, in combination with Figure 5 and Figure 6, the support member 11 is detachably mounted on the upper end of the base 17 through the mounting seat 13 and the supporting seat 14, and the first driving member 15 is mounted on the lower end of the base 17. With such an arrangement, it can save space and is beneficial to improving the integration degree.

[0055] Exemplarily, as Figure 6 shown, the mounting seat 13 is detachably mounted on the base 17 to facilitate adjusting the position of the support member 11 according to the requirements of the first flange 101.

[0056] Exemplarily, as Figure 6 shown, the supporting seat 14 is detachably mounted on the base 17 to facilitate adjusting the number and mounting position of the supporting seats 14 according to the specifications of the support member 11.

[0057] Exemplarily, as Figure 6 shown, a push rod seat 161 is mounted on the base 17. A guide sleeve cooperating with the push rod 16 is provided on the push rod seat 161. The push rod 16 passes through the guide sleeve and can move axially relative to the push rod seat 161 along the turntable 21. The push rod seat 161 is used to ensure the stability of the movement of the push rod 16, which is beneficial to improving the feeding efficiency.

[0058] In an exemplary solution, as Figure 3 shown, the feeding mechanism 10 further includes an adjusting portion 130, and the adjusting portion 130 can adjust the positions of the supporting portion 110 and the pushing portion 120 relative to the turntable 21.

[0059] Exemplarily, the adjusting portion 130 includes a slide rail and a slide seat. The slide seat is movably mounted on the slide rail, and the supporting portion 110 and the pushing portion 120 are mounted on the slide seat. By adjusting the extending direction of the slide rail, the movement direction of the slide seat can be adjusted, and thus the positions of the supporting portion 110 and the pushing portion 120 relative to the turntable 21 can be adjusted.

[0060] Optionally, as Figure 5 shown, the slide rail includes a first slide rail 18, and the first slide rail 18 extends in the up and down direction. The slide seat includes a first slide seat 181, and the first slide seat 181 is slidably mated with the first slide rail 18.

[0066] In an exemplary solution, as Figure 7 shown, the welding mechanism 40 includes a bolt fixing portion 41 and an end face protection portion 42. The bolt fixing portion 41 is configured to cooperate with the bolt hole of the second flange 102, and can fix the head of the bolt 100 in the bolt hole, so as to cooperate with the welding equipment to weld the bolt 100 into the bolt hole, which is beneficial to ensuring the perpendicularity of the bolt 100 and the second flange 102. The end face protection portion 42 includes a guard plate 421, and the guard plate 421 can cover the end face of the second flange 102 to prevent debris during the welding process from falling on the end face of the second flange 102 and damaging its flatness.

[0067] Exemplarily, the bolt fixing portion 41 includes a second driving member 411 and a pressing member 412. The output shaft of the second driving member 411 is connected to the pressing member 412, and is used to drive the pressing member 412 to move in the up - down direction, so as to contact the head of the bolt 100 and press the bolt 100 tightly in the bolt hole of the second flange 102, or separate from the bolt 100.

[0071] Optionally, the third driving member adopts a cylinder.

[0072] Optionally, the end face protection part 42 is integrated with one of the bolt fixing parts 41, that is, the guard plate 421 is connected to the output shaft of the second driving member 411. With such a setting, the input cost can be saved.

[0073] In an exemplary solution, a manipulator is provided between the turnover mechanism 30 and the welding mechanism 40 to stack the second flanges 102 neatly to cooperate with the positions of the bolt fixing part 41 and the end face protection part 42, and can put the bolts 100 into the bolt holes of the second flanges 102.

[0074] In an exemplary solution, as Figure 8 shown, the detection mechanism 50 includes a detection probe 51. The detection probe 51 is configured to be able to move in the up and down direction and can contact the rod part of the bolt 100 of the third flange 103.

If the detected pressure value is within the set range, it means that the welding of the bolt 100 is qualified. If the detected pressure value is too low or too high, it means that the welding of the bolt 100 is unqualified.

[0075] Exemplarily, the detection mechanism 50 includes a workbench for placing the third flange 104 to be detected.

[0076] In an exemplary solution, a manipulator is provided between the welding mechanism 40 and the detection mechanism 50 to transport the welded third flange 103 to the detection mechanism 50 for detection.

[0077] In an exemplary solution, as Figure 9As shown, the flange processing system proposed by the present invention further includes a palletizing mechanism 60. The palletizing mechanism 60 is used to stack a plurality of first flanges 101 along the axial direction to cooperate with the feeding mechanism 10, facilitating the feeding of the stacked first flanges 101 to the feeding mechanism 10 and realizing feeding and grinding through the feeding mechanism 10.

[0078] Exemplarily, as Figure 9 shown, the palletizing mechanism 60 includes a base 61 and positioning rods 62. The lower ends of the positioning rods 62 are connected to the upper end of the base 61. At least two positioning rods 62 are used to cooperate with the bolt holes of the first flange 101. The first flange 101 is sleeved on the positioning rods 62 through the bolt holes to realize the stacking of the first flanges 101, and the base 61 can support the first flange 101.

[0079] The positioning rods 62 are provided with at least two, which can limit the position of the first flange 101, prevent its angle from changing during the stacking process, and have high stacking efficiency.

[0080] As Figure 10 shown, the present invention also proposes a flange processing method, which is applied to the above flange processing system and includes the following steps: S1. The feeding mechanism 10 feeds the first flange 101 to the grinding mechanism 20; S2. The grinding mechanism 20 performs end face grinding on the first flange 101 to process the second flange 102; S3. The turnover mechanism 30 feeds the second flange 102 to the welding mechanism 40, and the welding mechanism 40 welds bolts 100 in the bolt holes of the second flange 102 to process the third flange 103; S4. After welding is completed, the third flange 103 is fed to the detection mechanism 50, and the detection mechanism 50 detects whether the bolts 100 are welded in place.

[0081] Exemplarily, the above step S2 further includes: The turntable 21 rotates to feed the first flange 101 to the grinding part 22 for end face grinding. After grinding is completed, the turntable 21 rotates to move the second flange 102 away from the grinding part 22. At the same time, the first flange 101 is fed to the grinding part 22 for grinding.

[0082] Exemplarily, the above step S2 further includes: The unloading mechanism applies a force along the axial direction of the turntable 21 to the second flange 102 in the positioning groove 23 to unload the second flange 102 to the turnover mechanism 30.

[0083] In an exemplary solution, when the flange processing system further includes a palletizing mechanism 60, the flange processing method proposed by the present invention further includes, before step S1: S0. Stack a number of first flanges 101 with bolt holes through a palletizing mechanism 60 and transport them to a feeding mechanism 10.

[0084] As described above, the above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
