Description

Technical Field

[0001] The invention relates to the field of pipe pile production, and in particular to a skirt plate assembly point rolling system. Background Art

[0002] As we all know, in the pipe pile industry, the skirt plate is composed of an end plate and an annular skirt belt; and in the assembly process of the skirt plate, the end plate and the annular skirt belt are first sleeved together, and then the sleeved end plate and the annular skirt belt are rotated together, and the rib pressing mechanism presses out annular ribs on the annular skirt belt to fix the annular skirt belt and the end plate together; therefore, the automated assembly of the skirt plate is inseparable from the use of assembly equipment.

[0003] However, in the existing assembly equipment, since it uses a rib pressing mechanism to roll out the annular ribs between the end plate and the annular skirt that are set together, and the end plate and the annular skirt that are set together need to rotate together during the process of pressing out the annular ribs, the assembly equipment applies a large top pressure to the end plate and the annular skirt that are set together, so as to prevent the end plate and the annular skirt from moving due to insufficient top pressure caused by the rib pressing mechanism during the process of rolling the annular ribs. Because the assembly equipment applies a large top pressure to the end plate and the annular skirt that are set together, there is a defect that causes the annular skirt to deform.

[0004] At the same time, since the fixation between the annular skirt and the end plate is achieved by means of the friction between the annular ribs and the end plate, the end plate and the annular skirt fixed together by the rib pressing mechanism are prone to relative rotation and falling off.

[0005] Therefore, there is an urgent need for a skirt panel assembly point rolling system to overcome one or more of the above-mentioned defects. Summary of the invention

[0006] The object of the present invention is to provide a skirt plate assembly point rolling system, which can greatly reduce the top pressure between the end plate and the annular skirt belt that are put together, and the deformation of the annular skirt belt caused by excessive top pressure, and on the other hand, improve the stability and reliability between the end plate and the annular skirt belt.

[0007] To achieve the above-mentioned purpose, the skirt assembly spot welding system of the present invention comprises an assembly spot welding machine and a roll welding machine arranged in sequence along the X-axis direction. The assembly spot welding machine comprises an assembly mechanism for fitting the end plate and the annular skirt together to obtain an assembly, and a spot welding mechanism connected to the assembly mechanism and used for circumferential spot welding between the end plate and the annular skirt in the assembly, and the roll welding machine is configured to perform circumferential roll welding on the spot-welded assembly transferred from the assembly spot welding machine.

[0008] Compared with the prior art, with the help of the cooperation of the assembling mechanism, the spot welding mechanism and the rolling welding machine, the process of "firstly putting the end plate and the annular skirt together by the assembling mechanism to obtain an assembly, then performing circumferential spot welding on the end plate and the annular skirt in the assembly by the spot welding mechanism, and then performing circumferential roll welding on the spot-welded assembly by the rolling welding machine" is realized. On the one hand, it can greatly reduce the top pressure between the end plate and the annular skirt that are put together, and the deformation of the annular skirt caused by excessive top pressure; on the other hand, it can improve the stability and reliability between the end plate and the annular skirt.

[0036] In order to explain the technical content and structural features of the present invention in detail, further description is given below in combination with the implementation modes and the accompanying drawings.

[0037] See also Figure 1 and Figure 2 The skirt assembly spot welding system 1000 of the present invention comprises an assembly spot welding machine 100 and a roll welding machine 200 arranged in sequence along the X-axis direction. The assembly spot welding machine 100 comprises a device for fitting an end plate 310 and an annular skirt belt 320 together to obtain a combined body 300' (see Fig. 9 ) and a spot welding mechanism 100b connected to the assembly mechanism 100a and used to perform circumferential spot welding between the end plate 310 and the annular skirt 320 in the assembly 300'. The roll welding machine 200 is configured to perform circumferential roll welding on the spot-welded assembly 300' transferred from the assembly spot welding machine 100, thereby obtaining Fig.25 The skirt plate 300 shown. Since the seam welding machine 200 is Fig.18 The position 330 between the end plate 310 and the annular skirt 320 of the assembly 300' is circumferentially rolled, so that Fig.25 In the skirt plate 300 shown, there is a circle of roll welding structure 340 between the end plate 310 and the annular skirt belt 320. Figure 1 and Figure 2 As an example, the skirt assembly spot welding system 1000 of the present invention further includes a transfer robot 400 and a material unloading channel 500 and a transfer material receiving mechanism 600 which are sequentially arranged between the assembly spot welding machine 100 and the rolling welding machine 200 along the X-axis direction, and combined with Fig. 27The material discharge channel 500 is arranged in an inclined manner, the upper end 510 of the material discharge channel 500 is connected to the assembly spot welding machine 100, and the lower end 520 of the material discharge channel 500 is connected to the transfer material receiving mechanism 600, so that the assembly 300' after spot welding by the assembly spot welding machine 100 can roll along the material discharge channel 500 to the transfer material receiving mechanism 600, and the transfer material receiving mechanism 600 performs transfer positioning on the assembly 300' transferred to the roll welding machine 200; the transfer manipulator 400 transfers the assembly 300' at the transfer material receiving mechanism 600 to the roll welding machine 200 to meet the needs of the roll welding machine 200 to perform circumferential roll welding on the assembly 300'. More specifically, as follows:

[0038] like Figure 1 and Figure 2 As shown, as an example, the roll welding machines 200 are arranged in two spaced apart from each other in the X-axis direction, so as to meet the needs of configuring two roll welding machines 200 with one transfer material receiving mechanism 600 and one transfer manipulator 400, thereby further improving the roll welding efficiency of the assembly 300'; obviously, according to actual needs, the number of the roll welding machines 200 can also be designed to be one or three, so it is not necessary to Figure 1 and Figure 2 In addition, the transfer robot 400 is a gantry robot, so that the transfer robot 400 can transfer the assembly 300' at the intermediate material receiving mechanism 600 to the seam welding machine 200 from above; obviously, according to actual needs, the transfer robot 400 can also be other types of robots, so it is not limited to the above. Figure 1 and Figure 2 Specifically, Fig. 27As an example, the intermediate material receiving mechanism 600 includes a mechanism frame 610, a pressing plate 620 and a pressing driver 630; the mechanism frame 610 is provided with a supporting and positioning structure 611 for supporting and positioning the assembly 300' rolled from the unloading channel 500, an anti-rolling plate 612 to prevent the assembly 300' from rolling out of the supporting and positioning structure 611, and a lateral blocking plate 613 for lateral blocking the assembly 300' positioned by the supporting and positioning structure 611 in the Y-axis direction. The plate 613 is arranged opposite to the pressing plate 620 along the Y-axis direction; the pressing driver 630 is assembled on the mechanism frame 610, and the mechanism frame 610 provides support for the pressing driver 630. The output end 631 of the pressing driver 630 is assembled and connected with the pressing plate 620, so that the pressing plate 620 moves closer to or away from the lateral blocking plate 631 under the action of the pressing driver 630, thereby correspondingly achieving the purpose of pressing or releasing the assembly 300' at the supporting positioning structure 611. For example, the pressing driver 630 can be a cylinder. Obviously, according to actual needs, the pressing driver 630 can also be a hydraulic cylinder, so it is not limited to this; in addition, the supporting positioning structure 611 is two shafts arranged apart from each other in the X-axis direction. Obviously, according to actual needs, the supporting positioning structure 611 can also be other types of positioning structures.

[0039] Among them, in the transfer material receiving mechanism 600, with the help of the anti-rolling plate 612, it is effectively ensured that the assembly 300' rolled from the unloading channel 500 is supported and positioned by the supporting and positioning structure 611; with the help of the cooperation of the pressing plate 620, the pressing driver 630 and the lateral blocking plate 631, it is ensured that the assembly 300' is accurately positioned at the supporting and positioning structure 611, thereby improving the reliability of the transfer robot 400 in transferring the assembly 300' at the transfer material receiving mechanism 600.

[0040] like Figure 3 , Figure 4 and Fig. 9 As shown, as an example, the assembly mechanism 100a includes a first stand 10a, a second stand 10b, a first pressing body 20, a second pressing body 30, and a pressing driver 40 (see Fig.11 ) and a material receiving and unloading device 60 for supporting the end plate 310 and the annular skirt 320 from below. The first stand 10a is arranged in a spaced relationship with the second stand 10b in the Y-axis direction; Figures 3 to 6 As shown in the figure, as an example, the lower ends of the first stand 10a and the second stand 10b are fixed to the base 10c, so that the first stand 10a and the second stand 10b are supported by an external support (such as the ground) by means of the base 10c; obviously, according to actual needs, the first stand 10a and the second stand 10b can also be directly fixedly connected to the external support, so it is not necessary to Figures 3 to 6Limits shown.

[0041] Another example Figure 3 , Figure 4 and Fig. 9 As shown, as an example, the first pressing body 20 and the second pressing body 30 are both located at the gap 10c between the first frame 10a and the second frame 10b, and the first pressing body 20 is mounted on the first frame 10a, and the first frame 10a provides support for the first pressing body 20; optionally, as an example, the first pressing body 20 can be rotatably mounted on the first frame 10a to meet the need for the first pressing body 20 to rotate relative to the first frame 10a; in addition, the first pressing body 20 is a plate-like structure, but is not limited to this. The second pressing body 30 is mounted on the second frame 10b, and the second frame 10b provides support for the second pressing body 30; optionally, as an example, the second pressing body 30 is rotatably mounted on the second frame 10b to meet the need for the second pressing body 30 to rotate relative to the second frame 10b; in addition, the second pressing body 30 is a plate-like structure, but not limited to this; the second pressing body 30 is also arranged in a relative separation from the first pressing body 20 in the Y-axis direction, and the second pressing body 30 is driven by the pressing driver 40 to reduce or expand the gap 23 between the first pressing body 20 and the second pressing body 30; obviously, according to actual needs, the pressing driver 40 can also be designed to drive the first pressing body 20 to slide, or the pressing driver 40 can be designed to drive the first pressing body 20 and the second pressing body 30 to slide respectively, so it is not necessary to Fig.11 Limits shown.

[0042] For example Figure 3 , Figure 4 and Fig. 9 As shown, as an example, the material receiving and unloading device 60 is placed at the gap 10c between the first stand 10a and the second stand 10b, and the material receiving and unloading device 60 also corresponds to the gap 23 between the first top pressing body 20 and the second top pressing body 30 upwards. The first top pressing body 20 and the second top pressing body 30 are driven by the top pressing driver 40 to put the end plate 310 and the annular skirt 320 supported by the material receiving and unloading device 60 together to obtain the assembly 300'. The spot welding mechanism 100b is connected to the first stand 10a, and the first stand 10a provides support for the spot welding mechanism 100b; specifically, at Fig.15As an example, the spot welding mechanism 100b can move relative to the assembly 300' to perform circumferential spot welding between the end plate 310 and the annular skirt 320 in the assembly 300', so as to achieve the purpose of pre-fixing the end plate 310 and the annular skirt 320 that are put together. Since the spot welding mechanism 100b performs spot welding between the end plate 310 and the annular skirt 320 in the circumferential direction of the assembly 300', the welding points are discontinuous and disconnected; optionally, as an example, the spot welding mechanism 100b spot welds three separated welding points from each other at the circumferential position between the end plate 310 and the annular skirt 320 of the assembly 300' from the outside of the assembly 300', but it is not limited to this. In addition, the more specific structure of the assembly mechanism 100a is described below.

[0043] like Figures 3 to 8 As shown, as an example, the assembly mechanism 100a further includes a partition plate 70a, a partition driver 70b for driving the partition plate 70a to rise and fall, a feed channel 80a corresponding to the gap 10c between the first stand 10a and the second stand 10b in the X-axis direction, and an anti-slip device 80b for blocking and limiting the end plate 310 and the annular skirt 320 feeding along the feed channel 80a. The upper end of the feed channel 80a is open, the partition plate 70a is correspondingly located above the feed channel 80a and is assembled and connected to the output end 71 of the partition driver 70b, and the partition plate 70a can move downward under the drive of the partition driver 70b, so that during the feeding process of the end plate 310 and the annular skirt 320, the partition plate 70a separates the end plate 310 and the annular skirt 320, thereby ensuring the reliability of the feeding of the end plate 310 and the annular skirt 320. The spot welding mechanism 100b is arranged opposite to the feeding channel 80a in the X-axis direction, so that the spot welding mechanism 100b and the feeding channel 80a are arranged on different sides of the second stand 10b, respectively. Figure 7 and Figure 8 As shown, the feeding of the end plate 310 and the annular skirt 320 and the spot welding of the spot welding mechanism 100b do not interfere with each other.

[0044] At the same time, the anti-overslip device 80b includes an anti-overslip driver 84 mounted on the first stand 10a and a blocking member 85 mounted on the output end 841 of the anti-overslip driver 84. The blocking member 85 is driven by the anti-overslip driver 84 to move into or out of the gap 10c between the first stand 10a and the second stand 10b along the Y-axis direction, so that during the feeding process of the end plate 310 and the annular skirt 320, the blocking member 85 moved into the gap 10c blocks the end plate 310 and the annular skirt 320 to prevent them from slipping excessively and causing the end plate 310 and the annular skirt 320 to be unable to be properly supported by the material receiving and unloading device 60, thereby ensuring the reliability of the material receiving and unloading device 60 in receiving the end plate 310 and the annular skirt 320. Specifically, Figures 5 to 8 In the embodiment, as an example, there are two blocking members 85 which are arranged one above the other and separated from each other, and each blocking member 85 corresponds to an anti-overslip driver 84. Such a design can accommodate the blocking needs of end plates 310 and annular skirts 320 of different sizes, that is, when the radial dimensions of both the end plate 310 and the annular skirt 320 are large, the upper blocking member 85 is used for blocking; when the radial dimensions of both the end plate 310 and the annular skirt 320 are small, the lower blocking member 85 is used for blocking. More specifically, as an example, the anti-overslip driver 84 can be a cylinder, and obviously, a hydraulic cylinder according to actual needs.

[0045] In addition, combined Figure 7 , Figure 8 and Fig.15 As an example, the spot welding mechanism 100b includes a two-axis transfer module 52 mounted on the first stand 10a and adjacent to the anti-slip device 80b, and a welding gun 51 driven by the two-axis transfer module 52. Optionally, Fig.15 As an example, the two-axis transfer module 52 includes a first-axis transfer module 521 and a second-axis transfer module 522. The first-axis transfer module 521 can be composed of a motor, a screw and a nut, and the second-axis transfer module 522 is a cylinder or a hydraulic cylinder, but it is not limited to this. Therefore, the first-axis transfer module 521 can be composed of a motor, a screw and a nut, and the second-axis transfer module 522 is a cylinder or a hydraulic cylinder, so that the welding gun 51 can slide in the X-axis direction and the Y-axis direction, thereby achieving the purpose of spot welding compatible with different sizes of assemblies 300'.

[0046] like Figures 7 to 10 As shown in the figure, as an example, the material receiving and unloading device 60 includes a fixed frame 61, a lifting material receiving frame 62, a telescopic unloading frame 63, an up and down lifting driver 64, an unloading driver 65 and an up and down lifting limit device 66. The lifting material receiving frame 62 is located above the fixed frame 61 to meet the need of lifting the lifting material receiving frame 62 to move up and down above the fixed frame 61; Figure 7 and Figure 8As an example, when the first stand 10a and the second stand 10b are fixed on the base 10c, the lower end of the fixed frame 61 can be fixed on the base 10c, and the base 10c provides support for the fixed frame 61. The up and down lifting driver 64 is assembled on the fixed frame 61, and the fixed frame 61 provides support for the up and down lifting driver 64; the output end 641 of the up and down lifting driver 64 is assembled and connected with the lifting receiving frame 62 to meet the needs of the up and down lifting driver 64 to drive the lifting receiving frame 62 to rise and fall. The top surface of the lifting receiving frame 62 has an inclined guide surface 621 inclined relative to the horizontal plane for guiding the movement of the end plate 310 and the annular skirt 320. The telescopic unloading frame 63 and the unloading driver 65 are each assembled on the lifting receiving frame 62 and located below the inclined guide surface 621. The telescopic unloading frame 63 can extend or retract from the inclined guide surface 621 under the drive of the unloading driver 65. The upper and lower lifting limit device 66 is assembled on the fixed frame 61 and is located at the corresponding lower part of the lifting material receiving frame 62. Therefore, by means of the lifting and lowering of the upper and lower lifting limit device 66, the lifting material receiving frame 62 is stopped and limited at different heights from the lower part, so as to ensure that the centers of the end plates 310 and the annular skirt 320 of different sizes are always kept in the appropriate positions before the first pressing body 20 and the second pressing body 30 assemble and press the end plates 310 and the annular skirt 320, for example, the end plates 310, the annular skirt 320, the first pressing body 20 and the second pressing body 40 are coaxial. Specifically, Figures 9 and 10 In the figure, as an example, the upper and lower lifting limit device 66 is a worm screw lift to accurately control the limit position of the upper and lower lifting limit device 66 on the lifting material receiving rack 62; the upper and lower lifting drivers 64 are respectively arranged beside the upper and lower lifting limit devices 66 on both sides opposite to each other, and the output end 641 of the upper and lower lifting driver 64 is arranged upward; such a design ensures the smooth and reliable lifting of the lifting material receiving rack 62. In addition, the lifting material receiving rack 62 is provided with a positioning structure 67 for positioning the end plate 310 and the annular skirt belt 320 when they move to a preset position along the inclined guide surface 621, so as to improve the reliability of the positioning of the end plate 310 and the annular skirt belt 320 by the lifting material receiving rack 62; the telescopic unloading rack 63 is placed in the positioning structure 67, so that the telescopic unloading rack 63 can eject the end plate 310 and the annular skirt belt 320 positioned by the positioning structure 67 to meet the need of unloading. More specifically, in Figures 9 and 10 As an example, the positioning structure 67 is two guide directions of the inclined guide surface 621 (see Fig. 9The bearing structures are separated from each other on the telescopic material receiving frame 62 (indicated by the arrow in the middle lifting material receiving frame 62), and the bearing structures protrude upward from the inclined guide surface 621, and the telescopic material unloading frame 63 is located between two adjacent bearing structures; this design improves the smoothness of the end plate 310 and the annular skirt 320 entering and exiting the positioning structure 67. In addition, the unloading driver 65 is located below the telescopic material unloading frame 63, and the output end 651 of the unloading driver 65 is arranged upward to simplify the assembly relationship between the unloading driver 65 and the telescopic material unloading frame 63. For example, the upper and lower lifting drivers 64 and the unloading driver 65 can be cylinders or hydraulic cylinders.

[0047] Among them, in the material receiving and unloading device 60, with the help of the up and down lifting drive 64, the lifting material receiving frame 62 can be lifted up to the docking position that is obliquely aligned with the feeding channel 80a and the unloading channel 500, so as to ensure the smoothness of the end plate 310 and the annular skirt 320 entering from the feeding channel 80a to the lifting material receiving frame 62, and the smoothness of the telescopic unloading frame 63 to eject the spot-welded assembly 300' out of the positioning structure 67 and unload the material into the unloading channel 500; with the help of the up and down lifting drive 64, the lifting frame 62 can be lifted up to the docking position that is obliquely aligned with the feeding channel 80a and the unloading channel 500. The lower lifting limit device 66 resists and limits the downwardly descending lifting material receiving frame 62, so that the centers of the end plate 310 and the annular skirt 320 supported by the lifting material receiving frame 62 are maintained in positions matching the centers of the first top pressing body 20 and the second top pressing body 30. For example, the end plate 310, the annular skirt 320, the first top pressing body 20 and the second top pressing body 30 are coaxially arranged to accommodate the needs of end plates 310 and annular skirts 320 of different sizes.

[0048] Combination Figure 5 , Figure 6 , Fig.11 , Fig.12 and Fig.14 The assembly mechanism 100a further comprises a bearing 80c mounted on the second stand 10b, a rotating ring 80d mounted on the bearing 80c, a fixed plate 80e fixedly connected to the rotating ring 80d, and a rotating driver 80f mounted on the second stand 10b and capable of driving the rotating ring 80d to rotate. The fixed plate 80e is located between the second pressing body 30 and the rotating ring 80d in the Y-axis direction. Figure 5 and Figure 6 As shown. The top pressure driver 40 is assembled on the fixed plate 80e and arranged on the side of the fixed plate 80e facing away from the second top pressure body 30. Therefore, with the help of the bearing 80c, the smoothness and flexibility of the rotation of the rotating ring 80d together with the fixed plate 80e and the second top pressure body 30 are ensured. Optionally, in combination with Figure 3 , Figure 4 and Fig.14As an example, the outer edge of the rotating ring body 80d is provided with a circle of meshing teeth 81, and the rotating driver 80f is correspondingly equipped with a gear 86 that is in transmission cooperation with the meshing teeth 81. Therefore, through the cooperation of the gear 86 and the meshing teeth 81, the rotating driver 80f drives the rotating ring body 80d together with the fixed plate 80e and the second pressing body 30 to rotate, so as to meet the need of the assembly 300' pressed by the first pressing body 20 and the second pressing body 30 to follow the rotation. For example, the rotating driver 80f is a motor, and the pressing driver 40 can be a cylinder or a hydraulic cylinder.

[0049] Combination Figures 11 to 13 As an example, the assembly mechanism 100a further includes a strip insertion device 90 for correcting the annular skirt 320 between the first pressing body 20 and the second pressing body 30. The second stand 10b is provided with a mounting frame 10e located on the side of the second stand 10b facing away from the first stand 10a and an intermediate support rod 10f fixing the mounting frame 10e and the fixing plate 80e together, so as to meet the need of the strip insertion device 90 rotating with the rotating ring 80d. Specifically, in combination with Figures 11 to 13 As an example, the strip device 90 includes a strip driver 91, a strip row, and a strip mounting plate 93 located between the fixed plate 80e and the mounting frame 10e in the Y-axis direction. The strip row includes a plurality of strips 921 arranged in a circle on the strip mounting plate 93, and the second pressing body 30 is provided with a through hole 31 for the strips 921 to pass through; the strip driver 91 is assembled on the mounting frame 10e, and the output end 911 of the strip driver 91 is assembled and connected to the strip mounting plate 93, and the strip driver 91 drives the strip mounting plate 93 together with the strip row to move closer to or away from the first pressing body 20. In the process of the first pressing body 20 and the second pressing body 30 approaching each other, the end plate 310 placed between the first pressing body 210 and the second pressing body 30 is also sleeved with the corrected annular skirt 320 to improve the reliability of the end plate 310 and the annular skirt 320 being assembled. More specifically, in Fig.13 In the embodiment, as an example, the insert strip mounting plate 93 is a ring structure 931 with four rings and each ring can slide along the Y-axis direction. Each ring structure 931 is provided with an insert strip row, and each ring structure 931 is assembled and connected with the output ends 911 of two insert strip drivers 91. This design enables each model of the annular skirt 320 to be corrected by the insert strip row on the corresponding annular structure 931, thus ensuring that the insert strip rows on each ring structure 931 do not interfere with each other. It is worth noting that although Fig.13 Only one of the inserting strips 931 on the corresponding annular structure 931 is shown, but the remaining inserting strips 931 of the annular structure 931 are hidden. In addition, the inserting strip device 90 corrects the annular skirt 320 by inserting it into the annular skirt 320. In addition, the inserting strip driver 91 can be a cylinder or a hydraulic cylinder.

[0050] Among them, in the assembly spot welding machine 100, with the aid of the material receiving and unloading device 60, for the skirt plates 300 of different specifications (referring to the ring diameter), the center of the end plate 310 and the annular skirt belt 320 constituting the skirt plate 300 is kept at a position corresponding to the center of the first pressing body 20 and the second pressing body 30. For example, the end plate 310, the annular skirt belt 320, the first pressing body 20 and the second pressing body 30 are coaxially arranged, thereby ensuring that the first pressing body 20 and the second pressing body 30 can fit the end plate 310 and the annular skirt belt 320 in the corresponding position. The reliability of the assembly 300' (i.e., the end plate 310 and the annular skirt 320 that are sheathed together) is improved by means of the spot welding mechanism 100b, and the circumferential spot welding is performed between the end plate 310 and the annular skirt 320 in the assembly 300' (i.e., the end plate 310 and the annular skirt 320 that are sheathed together), so as to achieve the purpose of pre-fixing the sheathed end plate 310 and the annular skirt 320, and prepare for the subsequent roll welding of the roll welding machine 200; therefore, the top pressure between the sheathed end plate 310 and the annular skirt 320, as well as the deformation of the annular skirt 320 caused by excessive top pressure can be greatly reduced.

[0051] like Figures 16 to 18 As shown, as an example, the seam welding machine 200 includes a supporting assembly 210, a rotating drive 220, a first side follower pressing member 230, a sliding body 240, a sliding drive 250, a second side follower pressing member 260 and a welding gun 270. The supporting assembly 210 includes a first supporting shaft 211 and a second supporting shaft 212 which are spaced apart and parallel to each other in the X-axis direction, and the first supporting shaft 211 and the second supporting shaft 212 exceed the first side follower pressing member 230 in the Y-axis direction, as shown in FIG. Fig.19 The rotation driver 220 is configured to drive the first supporting shaft 211 and the second supporting shaft 212 to rotate, so as to meet the need that the first supporting shaft 211 and the second supporting shaft 212 each act as an active force to drive the spot-welded assembly 300' to rotate together; obviously, according to actual needs, the rotation driver 220 can also be designed to drive the first supporting shaft 211 or the second supporting shaft 212 to rotate; optionally, Fig. 22 As an example, the rotary driver 220 is located below the first supporting shaft 211 and the second supporting shaft 212, so that a more sufficient space is provided for the arrangement of the first side follower pressure member 230 above the supporting assembly 210; in addition, the output end 221 of the rotary driver 220, the first supporting shaft 211 and the second supporting shaft 212 are equipped with a sprocket 290e, and the sprocket 290e is connected by a chain transmission to achieve the purpose of synchronous rotation of the first supporting shaft 211 and the second supporting shaft 212 by the cooperation of the sprocket 290e and the chain; obviously, according to actual needs, a pulley and a belt can also be used to replace the sprocket 290e and the chain, so it is not necessary to use a pulley and a belt. Fig.16, Fig.17 and Fig. 22 Limits shown.

[0052] The second side follower pressing member 260 is arranged opposite to the first side follower pressing member 230 in the Y-axis direction, so as to meet the need that the second side follower pressing member 260 and the first side follower pressing member 230 jointly press the assembly 300' after spot welding in the Y-axis direction; the second side follower pressing member 260 and the welding gun 270 are both assembled on the sliding body 240, so as to meet the need that the second side follower pressing member 260 and the welding gun 270 slide following the sliding body 240. The sliding body 240 can be arranged to slide back and forth along the Y-axis direction, and the sliding driver 250 is configured to drive the sliding body 240 to slide close to or away from the supporting assembly 210.

[0053] Therefore, during the roll welding process, the sliding driver 250 uses the sliding body 240 to make the second side follower pressing member 260 and the first side follower pressing member 230 jointly press the spot-welded assembly 300' supported by the supporting assembly 210 in the Y-axis direction; then, the rotating driver 220 drives the first supporting shaft 211 and the second supporting shaft 212 to rotate synchronously, and the synchronously rotating first supporting shaft 211 and the second supporting shaft 212 jointly drive the spot-welded assembly 300' to rotate together, so that the welding gun 270 welds a circle of continuous or discontinuous roll welding structure 340 between the end plate 310 and the annular skirt 320 of the assembly 300', so as to obtain Fig.25 The skirt plate 300 is shown. In addition, regarding the more specific structure of the seam welding machine 200, see the following description.

[0054] like Figures 16 to 18 and Figure 23 to Figure 24 As shown, as an example, the sliding body 240 includes a horizontal base 241 and a vertical plate 242 connected to the horizontal base 241. The second side follower pressure piece 260 is assembled on the side of the vertical plate 242 facing the first side follower pressure piece 230. The vertical plate 242 is also provided with an escape space 2421, and the welding gun 270 is placed in the escape space 2421. This design makes the assembly of the second side follower pressure piece 260 on the sliding body 240 more compact, and also enables the vertical plate 242 to provide a barrier function during the roll welding process to prevent the roll welding sparks from splashing on the X-axis transfer module 290a, the Y-axis transfer module 290c and the Z-axis transfer module 290b described below. Specifically, Fig.17 and Fig.24As an example, the second side follower pressing member 260 includes a first follower pressing shaft 261 and a second follower pressing shaft 262 that are inclined relative to each other and separated, the lower ends 2611 (2621) of the first follower pressing shaft 261 and the second follower pressing shaft 262 are close to each other, and the welding gun 270 is arranged in the gap 2613 between the lower ends 2611 (2621) of the first follower pressing shaft 261 and the second follower pressing shaft 262; such a design enables the second side follower pressing member 260 to be compatible with the roll welding operation of the assembly 300' of different sizes (referring to radial size), thereby improving the versatility of the roll welding machine 200.

[0055] like Fig.23 and Fig.24 As shown, as an example, the seam welding machine 200 further includes a fixed base 280 located directly below the horizontal base 241, and the horizontal base 241 is slidably arranged on the fixed base 280 along the Y-axis direction, and the fixed base 280 provides support for the reciprocating sliding of the sliding body 240 in the Y-axis direction; a bracket 281 is provided on the fixed base 280, which is higher than the horizontal base 241 in the Z-axis direction, and the sliding driver 250 is assembled on the bracket 281; at this time, the side of the vertical plate 242 facing away from the first side follower top pressure piece 230 is arranged opposite to the sliding driver 250, and the output end of the sliding driver 250 is assembled and connected with the horizontal base 241, and the state is shown in FIG. Fig.23 As shown; this design has the advantage of being more compact than the sliding drive 250 being arranged between the vertical plate 242 and the supporting assembly 210. Specifically, Fig.23 and Fig.24 As an example, the sliding drive 250 may be, but is not limited to, a pneumatic cylinder or a hydraulic cylinder, so that the sliding body 240 can be quickly switched between two extreme positions, thereby improving the efficiency of the seam welding machine 200.

[0056] like Figures 16 to 18 and Figure 23 to Figure 24 As shown, as an example, the roll welding machine 200 further includes an X-axis transfer module 290a mounted on the horizontal base 241, a Z-axis transfer module 290b mounted on the output end 291 of the X-axis transfer module 290a, and a Y-axis transfer module 290c mounted on the output end 292 of the Z-axis transfer module 290b, and the welding gun 270 is mounted on the output end 293 of the Y-axis transfer module 290c; therefore, when roll welding assemblies 300' of different sizes, the position of the welding gun 270 can be accurately adjusted by the X-axis transfer module 290a, the Y-axis transfer module 290c and the Z-axis transfer module 290b, thereby ensuring the reliability of the roll welding of the assembly 300'. Specifically, Fig.23As an example, the output end 293 of the Y-axis transfer module 290c is connected to an L-shaped adapter 290d, and the L-shaped adapter 290d includes a first extension section 294 extending along the Z-axis direction and connected to the output end 293 and a second extension section 295 extending along the Y-axis direction and away from the output end 293. The welding gun 270 is installed in the second extension section 295. Fig.23 As shown; therefore, with the help of the L-shaped adapter 290d, the welding gun 270 is staggered with the Y-axis transfer module 290c in the Z-axis direction. For example, as an example, the X-axis transfer module 290a, the Y-axis transfer module 290c and the Z-axis transfer module 290b can all be composed of a structure consisting of a motor, a screw rod and a nut, but it is not limited to this.

[0057] like Figure 19 to Figure 20 As shown, as an example, the seam welding machine 200 further includes carbon brushes 290f respectively located in contact with each other directly above the first supporting shaft 211 and the second supporting shaft 212. A first side follower pressure piece 230 is provided at the center between the first supporting shaft 211 and the second supporting shaft 212, and there are two first side follower pressure pieces 230; a first side follower pressure piece 230 close to the carbon brush 290f is provided between the carbon brushes 290f, and there are two first side follower pressure pieces 230; six first side follower pressure pieces 230 arranged in an inverted "eight" shape are provided above the carbon brushes 290f. Specifically, as an example, the first side follower pressure piece 230 is a universal ball to effectively reduce the friction resistance between the first side follower pressure piece 230 and the end plate 310.

[0058] like Figures 1 to 7 As shown, as an example, the support assembly 210, the rotary driver 220, the carbon brush 90f and the first side follower pressing member 230 are each assembled on a carrier body 290g, and the carrier body 290g is arranged opposite to the sliding body 240 in the Y-axis direction. In addition, the rotary driver 220 can be a motor but is not limited thereto.

[0059] The rolling welding process of the rolling welding machine 300 is as follows: the transfer manipulator 400 takes away the spot-welded assembly 300' at the transfer material receiving mechanism 600 and places it on the first supporting shaft 211 and the second supporting shaft 212, and the first supporting shaft 211 and the second supporting shaft 212 support the assembly 300' from below, and the first side follower pressing member 230 presses the end plate 310 in the assembly 300'; then, the sliding driver 250 drives the sliding body 240 together with the second side follower pressing member 260 and the welding gun 270 to slide in the direction close to the first follower pressing member 230 until the second side follower pressing member 260 presses on the annular portion of the assembly 300'. The first side follower pressing piece 330 is mounted on the skirt 320, and together with the first side follower pressing piece 330, the assembly 300' is pressed in the Y-axis direction, and at this time, the welding gun 270 is located in the annular skirt 320 of the assembly 300'; then, the first supporting shaft 211 and / or the second supporting shaft 212 are driven by the rotating driver 220 to rotate, so that the assembly 300' after spot welding is driven by the rotating first supporting shaft 211 and / or the second supporting shaft 212 to rotate together, thereby achieving the purpose of circumferential roll welding between the end plate 310 and the annular skirt 320 in the assembly 300' by the welding gun 70, so as to improve the stability and reliability between the end plate 310 and the annular skirt 320 in the skirt plate 300.

[0060] Compared with the prior art, with the cooperation of the assembly mechanism 100a, the spot welding mechanism 100b and the rolling welder 200, the process of "firstly assembling the end plate 310 and the annular skirt 320 together by the assembly mechanism 100a to obtain the assembly 300', then performing circumferential spot welding between the end plate 310 and the annular skirt 320 in the assembly 300' by the spot welding mechanism 100b, and then performing circumferential rolling welding on the spot-welded assembly 300' by the rolling welder 200" is realized. On the one hand, the top pressure between the end plate 310 and the annular skirt 320 that are assembled together, as well as the deformation of the annular skirt 320 caused by excessive top pressure, can be greatly reduced; on the other hand, the stability and reliability between the end plate 310 and the annular skirt 320 can be improved.
