Description

Technical Field

[0001] This utility model relates to the field of pipe pile production, and in particular to a skirt assembly point rolling system. Background Technology

[0002] As is well known, in the pipe pile industry, skirts are composed of end plates and annular skirts. In the assembly process of skirts, the end plates and annular skirts are first connected together. Then, the connected end plates and annular skirts are rotated together, and the rib pressing mechanism presses out the annular ribs on the annular skirts to fix the annular skirts to the end plates. Therefore, the automated assembly of skirts is inseparable from the use of assembly equipment.

[0003] However, in existing assembly equipment, because a pressing mechanism rolls out ring ribs between the assembled end plates and annular skirts to fix them together, and the assembled end plates and annular skirts need to rotate together during the pressing process, the assembly equipment applies a large top pressure to the assembled end plates and annular skirts to prevent them from shifting due to insufficient top pressure during the rolling process. Because of this large top pressure applied to the assembled end plates and annular skirts, there is a defect that can cause deformation of the annular skirts.

[0004] Meanwhile, since the annular skirt is fixed to the end plate by means of the friction between the ring rib and the end plate, the end plate and the annular skirt, which are fixed together by the rib mechanism, are prone to relative rotation and detachment.

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

[0006] The purpose of this utility model is to provide a skirt assembly point rolling system, which can greatly reduce the top pressure between the end plate and the annular skirt belt that are assembled together, as well as the deformation of the annular skirt belt caused by excessive top pressure, and improve the stability and reliability between the end plate and the annular skirt belt.

[0007] To achieve the above objectives, the skirt assembly spot welding system of this utility model includes an assembly spot welding machine and a roll welding machine arranged sequentially along the X-axis. The assembly spot welding machine includes 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 for performing circumferential spot welding between the end plate and the annular skirt in the assembly. The roll welding machine is configured to perform circumferential roll welding on the assembled assembly that has already been spot welded and transferred from the assembly spot welding machine.

[0008] Compared with existing technologies, by using the combination of assembly mechanism, spot welding mechanism and roll welding machine, the process of "first assembling the end plate and annular skirt together by the assembly mechanism to obtain the assembly, then spot welding the end plate and annular skirt in the assembly by the spot welding mechanism, and finally roll welding the assembled assembly by the roll welding machine" can be realized. On the one hand, it can greatly reduce the top pressure between the assembled end plate and annular skirt, as well as 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. Attached Figure Description

[0036] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0037] Please see Figure 1 and Figure 2 The skirt assembly spot welding system 1000 of this utility model includes an assembly spot welding machine 100 and a roll welding machine 200 arranged sequentially along the X-axis direction. The assembly spot welding machine 100 includes a tool for fitting the end plate 310 and the annular skirt 320 together to obtain the assembly 300' (see...). Figure 9 The assembly mechanism 100a and the spot welding mechanism 100b connected to the assembly mechanism 100a and used for 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 assembly 300' that has been spot welded and transferred from the assembly spot welding machine 100, thereby obtaining Figure 25 The skirt panel 300 is shown. Due to the rolling welding machine 200 at... Figure 18 The end plate 310 of the assembly 300' and the annular skirt 320 are circumferentially rolled at position 330, therefore... Figure 25 In the skirt panel 300 shown, there is a ring of roll-welded structure 340 between its end plate 310 and the annular skirt belt 320. Specifically, in conjunction with Figure 1 and Figure 2 As an example, the skirt assembly spot welding system 1000 of this utility model also includes a transfer robot 400 and a material unloading channel 500 and a transfer receiving mechanism 600 arranged sequentially between the assembly spot welding machine 100 and the roll welding machine 200 along the X-axis direction, and combined with Figure 27The feeding channel 500 is arranged at an angle. The upper end 510 of the feeding channel 500 connects to the assembly spot welding machine 100, and the lower end 520 connects to the transfer receiving mechanism 600. This allows the assembled body 300', after spot welding by the assembly spot welding machine 100, to roll along the feeding channel 500 to the transfer receiving mechanism 600. The transfer receiving mechanism 600 then positions the assembled body 300' before it is transferred to the roll welding machine 200. The transfer robot 400 then transfers the assembled body 300' from the transfer receiving mechanism 600 to the roll welding machine 200, so that the roll welding machine 200 can perform circumferential roll welding on the assembled body 300'. More specifically, as follows:

[0038] like Figure 1 and Figure 2 As shown, as an example, two roll welding machines 200 are arranged spaced apart from each other in the X-axis direction to meet the needs of a transfer receiving mechanism 600 and a transfer robot 400 to configure the two roll welding machines 200, thereby further improving the roll welding efficiency of the assembly 300'. Obviously, depending on actual needs, the number of roll welding machines 200 can also be designed to be one or three, so it is not limited to one. Figure 1 and Figure 2 The description is limited to what is shown. Furthermore, the transfer robot 400 is a gantry robot to facilitate the transfer of the assembly 300' from the intermediate receiving mechanism 600 to the welding machine 200 from above; obviously, depending on actual needs, the transfer robot 400 could also be other types of robots, therefore, it is not limited to this description. Figure 1 and Figure 2 As shown, this is a limited description. Specifically, at... Figure 27As an example, the transfer receiving mechanism 600 includes a mechanism frame 610, a pressure plate 620, and a pressure driver 630. The mechanism frame 610 is provided with a support and positioning structure 611 for supporting and positioning the assembly 300' rolling in from the unloading channel 500, an anti-roll-out plate 612 to prevent the assembly 300' from rolling out of the support and positioning structure 611, and a lateral blocking plate 613 in the Y-axis direction to laterally block the assembly 300' positioned by the support and positioning structure 611. Plate 613 is arranged opposite to the aligning plate 620 along the Y-axis. Alignment actuator 630 is mounted on the frame 610, which provides support. The output end 631 of the actuator 630 is connected to the aligning plate 620 to allow the aligning plate 620 to move closer to or further away from the lateral blocking plate 631 under the action of the actuator 630, thereby correspondingly achieving the purpose of aligning or releasing the assembly 300' at the supporting positioning structure 611. For example, the actuator 630 can be a cylinder; obviously, depending on actual needs, it can also be a hydraulic cylinder, so it is not limited thereto. Furthermore, the supporting positioning structure 611 consists of two shafts arranged spaced apart from each other in the X-axis direction; obviously, depending on actual needs, the supporting positioning structure 611 can also be other types of positioning structures.

[0039] In the transfer receiving mechanism 600, the anti-roll-out plate 612 effectively ensures that the assembly 300' rolling from the unloading channel 500 is supported and positioned by the support and positioning structure 611; with the cooperation of the pressure plate 620, the pressure driver 630 and the side blocking plate 631, the assembly 300' is accurately positioned at the support and positioning structure 611, thereby improving the reliability of the transfer robot 400 in transferring the assembly 300' at the transfer receiving mechanism 600.

[0040] like Figure 3 , Figure 4 and Figure 9 As shown, as an example, the assembly mechanism 100a includes a first support 10a, a second support 10b, a first pressing body 20, a second pressing body 30, and a pressing actuator 40 (see...). Figure 11 ) and a receiving and unloading device 60 for supporting the end plate 310 and the annular skirt 320 from below. The first upright 10a is arranged opposite to the second upright 10b in the Y-axis direction; alternatively, in Figures 3 to 6 As shown, as an example, the lower ends of both the first upright 10a and the second upright 10b are fixed to the base 10c, so that the first upright 10a and the second upright 10b can be supported by an external support (such as the ground) with the aid of the base 10c; obviously, depending on actual needs, the first upright 10a and the second upright 10b can also be directly fixed to the external support, so it is not necessary to... Figures 3 to 6The above is the limit.

[0041] For example Figure 3 , Figure 4 and Figure 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 upright 10a and the second upright 10b. The first pressing body 20 is assembled on the first upright 10a, and the first upright 10a provides support for the first pressing body 20. Alternatively, as an example, the first pressing body 20 is rotatably assembled on the first upright 10a to meet the need for the first pressing body 20 to rotate relative to the first upright 10a. In addition, the first pressing body 20 has a plate-like structure, but is not limited to this. The second pressing body 30 is assembled on the second upright 10b, and the second upright 10b provides support for the second pressing body 30. Alternatively, as an example, the second pressing body 30 is rotatably assembled on the second upright 10b to meet the need for the second pressing body 30 to rotate relative to the second upright 10b. Furthermore, the second pressing body 30 has a plate-like structure, but is not limited to this. The second pressing body 30 is also arranged relatively apart from the first pressing body 20 in the Y-axis direction. Under the drive of the pressing actuator 40, the gap 23 between the first pressing body 20 and the second pressing body 30 narrows or widens. Obviously, depending on actual needs, the pressing actuator 40 can also be designed to drive the first pressing body 20 to slide, or the pressing actuator 40 can be designed to drive the first pressing body 20 and the second pressing body 30 to slide respectively. Therefore, it is not limited to this. Figure 11 The above is the limit.

[0042] For example Figure 3 , Figure 4 and Figure 9 As shown, as an example, the receiving and unloading device 60 is positioned at the gap 10c between the first upright 10a and the second upright 10b. The receiving and unloading device 60 also corresponds upwards to the gap 23 between the first pressing body 20 and the second pressing body 30. Driven by the pressing driver 40, the first pressing body 20 and the second pressing body 30 fit together the end plate 310 supported by the receiving and unloading device 60 and the annular skirt 320 to obtain the assembly 300'. The spot welding mechanism 100b is connected to the first upright 10a, and the first upright 10a provides support for the spot welding mechanism 100b; specifically, in... Figure 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', thereby pre-fixing the assembled end plate 310 and annular skirt 320. Since the spot welding mechanism 100b performs spot welding between the end plate 310 and annular skirt 320 in the circumferential direction of the assembly 300', the weld points are discontinuous and broken. Alternatively, as an example, the spot welding mechanism 100b can spot weld three spaced-apart weld points from the outside of the assembly 300' to the circumferential position between the end plate 310 and annular skirt 320, but this is not a limitation. For a more specific structure of the assembly mechanism 100a, see the description below.

[0043] like Figures 3 to 8 As shown, as an example, the assembly mechanism 100a further includes a partition plate 70a, a partition drive 70b for driving the partition plate 70a up and down, a feed channel 80a corresponding in the X-axis direction to the gap 10c between the first stand 10a and the second stand 10b, 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, and the partition plate 70a is correspondingly located above the feed channel 80a and assembled and connected to the output end 71 of the partition drive 70b. The partition plate 70a can move downward under the drive of the partition drive 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 feed channel 80a in the X-axis direction, so that the spot welding mechanism 100b and the feed channel 80a are respectively arranged on different sides of the second stand 10b, as shown in the figure. Figure 7 and Figure 8 As shown, this ensures that the feeding of the end plate 310 and the annular skirt 320 does not interfere with the spot welding of the spot welding mechanism 100b.

[0044] Meanwhile, the anti-slip device 80b includes an anti-slip driver 84 mounted on the first upright 10a and a blocking member 85 mounted on the output end 841 of the anti-slip driver 84. Driven by the anti-slip driver 84, the blocking member 85 moves into or out of the gap 10c between the first upright 10a and the second upright 10b along the Y-axis direction. During the feeding process of the end plate 310 and the annular skirt 320, the blocking member 85, moving into the gap 10c, blocks the end plate 310 and the annular skirt 320, preventing them from slipping excessively and thus ensuring the reliability of the receiving and unloading device 60 in receiving the end plate 310 and the annular skirt 320. Specifically, in Figures 5 to 8 In this example, the blocking members 85 are arranged in two, one above the other, with each blocking member 85 corresponding to an anti-slip actuator 84. This 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 end plates 310 and annular skirts 320 are large, the upper blocking member 85 is used for blocking; when the radial dimensions of both end plates 310 and annular skirts 320 are small, the lower blocking member 85 is used for blocking. More specifically, as an example, the anti-slip actuator 84 can be a cylinder, obviously, a hydraulic cylinder depending on the actual needs.

[0045] Additionally, in combination Figure 7 , Figure 8 and Figure 15 As an example, the spot welding mechanism 100b includes a biaxial transfer module 52 mounted on the first stand 10a and adjacent to the anti-slip device 80b, and a welding torch 51 driven by the biaxial transfer module 52. Optionally, in Figure 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 lead screw, and a lead nut, while the second-axis transfer module 522 can be a pneumatic or hydraulic cylinder, but is not limited thereto. Therefore, by using a first-axis transfer module 521 composed of a motor, a lead screw, and a lead nut, and a second-axis transfer module 522 being a pneumatic or hydraulic cylinder, the welding torch 51 can slide in both the X-axis and Y-axis directions, thereby achieving the purpose of spot welding assemblies 300' of different sizes.

[0046] like Figures 7 to 10 As shown in the illustration, the material receiving and unloading device 60 includes a fixed frame 61, a lifting receiving frame 62, a telescopic unloading frame 63, a vertical lifting driver 64, an unloading driver 65, and a vertical lifting limit device 66. The lifting receiving frame 62 is located above the fixed frame 61 to meet the need for the lifting receiving frame 62 to move up and down above the fixed frame 61; alternatively, it may be located above the fixed frame 61. Figure 7 and Figure 8In this example, when the first upright 10a and the second upright 10b are fixed to the base 10c, the lower end of the fixed frame 61 can be fixed to the base 10c, with the base 10c providing support for the fixed frame 61. The lifting actuator 64 is mounted on the fixed frame 61, with the fixed frame 61 providing support for the lifting actuator 64. The output end 641 of the lifting actuator 64 is connected to the lifting receiving frame 62 to meet the need for the lifting actuator 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 with a feed end plate 310 inclined relative to the horizontal plane and an annular skirt 320 guiding its movement. The telescopic unloading frame 63 and the unloading actuator 65 are each mounted on the lifting receiving frame 62 and located below the inclined guide surface 621. The telescopic unloading frame 63 can extend into or retract from the inclined guide surface 621 under the drive of the unloading actuator 65. The vertical lifting limit device 66 is mounted on the fixed frame 61 and located below the lifting receiving frame 62. Therefore, by raising and lowering the vertical lifting limit device 66, the lifting receiving frame 62 is stopped and limited at different heights from below. This ensures that the centers of the end plates 310 and annular skirts 320 of different sizes remain in a suitable position before the first pressing body 20 and the second pressing body 30 assemble and press against the end plates 310 and annular skirts 320. For example, the end plates 310, annular skirts 320, first pressing body 20, and second pressing body 40 are coaxial. Specifically, in Figures 9 to 10 In this example, the vertical lifting limit device 66 is a worm gear screw jack to precisely control the limiting position of the vertical lifting limit device 66 on the lifting receiving frame 62; the vertical lifting drive 64 is respectively arranged on both sides of the vertical lifting limit device 66, with the output end 641 of the vertical lifting drive 64 facing upward; this design ensures the smooth and reliable lifting of the lifting receiving frame 62. Furthermore, the lifting receiving frame 62 is provided with a positioning structure 67 for positioning the end plate 310 and the annular skirt 320 when they move along the inclined guide surface 621 to a preset position, thereby improving the reliability of the positioning of the end plate 310 and the annular skirt 320 by the lifting receiving frame 62; the telescopic unloading frame 63 is placed in the positioning structure 67 to facilitate the unloading of the end plate 310 and the annular skirt 320 positioned by the positioning structure 67. More specifically, in Figures 9 to 10 In the example, the positioning structure 67 has two guiding directions on the inclined guide surface 621 (see...). Figure 9The bearing structures (indicated by the arrow within the lifting receiving frame 62) are spaced apart from each other, with the bearing structures protruding upwards from the inclined guide surface 621. The telescopic 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. Furthermore, the unloading actuator 65 is located below the telescopic unloading frame 63, with its output end 651 facing upwards to simplify the assembly relationship between the unloading actuator 65 and the telescopic unloading frame 63. For example, the lifting actuator 64 and the unloading actuator 65 can be pneumatic or hydraulic cylinders.

[0047] In the receiving and unloading device 60, the lifting receiving frame 62 can be raised to a docking position that is inclined and aligned with the feeding channel 80a and the unloading channel 500 by means of the lifting drive 64. This ensures the smooth flow of the end plate 310 and the annular skirt 320 entering from the feeding channel 80a to the lifting receiving frame 62, and the smooth flow of the telescopic unloading frame 63 pushing the spot-welded assembly 300' out of the positioning structure 67 and unloading it into the unloading channel 500. The lower lifting limit device 66 blocks and limits the downward-descending lifting receiving frame 62, thereby ensuring that the center of the end plate 310 and the annular skirt 320 supported by the lifting receiving frame 62 is matched with the center of the first pressing body 20 and the second pressing body 30. For example, the end plate 310, the annular skirt 320, the first pressing body 20 and the second pressing body 30 are arranged coaxially to accommodate the needs of end plates 310 and annular skirts 320 of different sizes and specifications.

[0048] Combination Figure 5 , Figure 6 , Figure 11 , Figure 12 and Figure 14 The assembly mechanism 100a further includes a bearing 80c mounted on the second support frame 10b, a rotating ring 80d sleeved on the bearing 80c, a fixing plate 80e fixedly connected to the rotating ring 80d, and a rotary driver 80f mounted on the second support frame 10b and capable of driving the rotating ring 80d to rotate. The fixing plate 80e is located between the second pressing body 30 and the rotating ring 80d in the Y-axis direction, as shown in the figure. Figure 5 and Figure 6 As shown. The top pressure actuator 40 is mounted on the fixed plate 80e and positioned on the side of the fixed plate 80e opposite to the second top pressure body 30. Therefore, the bearing 80c ensures 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. Alternatively, it can be combined with... Figure 3 , Figure 4 and Figure 14As an example, the outer edge of the rotating ring 80d is provided with a ring of meshing teeth 81, and the rotary actuator 80f is correspondingly equipped with a gear 86 that engages with the meshing teeth 81. Therefore, through the cooperation of the gear 86 and the meshing teeth 81, the rotary actuator 80f drives the rotating ring 80d, together with the fixed plate 80e and the second pressing body 30, to rotate together, so as to meet the need for the assembly 300' pressed by the first pressing body 20 and the second pressing body 30 to rotate accordingly. For example, the rotary actuator 80f is a motor, and the pressing actuator 40 can be a cylinder or a hydraulic cylinder.

[0049] Combination Figures 11 to 13 As an example, the assembly mechanism 100a also includes an insert device 90 for aligning 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 opposite to the first stand 10a, and an intermediate support rod 10f that fixes the mounting frame 10e to the fixing plate 80e, to meet the requirement that the insert device 90 rotates with the rotating ring 80d. Specifically, in conjunction with... Figures 11 to 13 As an example, the insert device 90 includes an insert driver 91, an insert bar array, and an insert mounting plate 93 located in the Y-axis direction between the fixed plate 80e and the mounting frame 10e. The insert bar array includes a plurality of inserts 921 arranged in a circle on the insert mounting plate 93. The second pressing body 30 has through holes 31 for the inserts 921 to pass through. The insert driver 91 is mounted on the mounting frame 10e, and its output end 911 is mounted to the insert mounting plate 93. The insert driver 91 drives the insert mounting plate 93, together with the insert bar array, to move closer to or away from the first pressing body 20. During 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 sleeve of the end plate 310 and the annular skirt 320. More specifically, in Figure 13 In this example, the insert mounting plate 93 is a four-ringed annular structure 931, each ring sliding along the Y-axis. Each ring 931 has an insert bar array, and each ring 931 is assembled and connected to the output terminals 911 of two insert drivers 91. This design ensures that each type of annular skirt 320 is aligned by the insert bar array on the corresponding ring 931, thus ensuring that the insert bar arrays on each ring 931 do not interfere with each other. It is worth noting that, although Figure 13 Only one insert 931 on the corresponding annular structure 931 is displayed; however, the remaining inserts 931 on the annular structure 931 are hidden. Additionally, the insert device 90 aligns the annular skirt 320 by inserting it into the annular skirt 320. Furthermore, the insert driver 91 can be a pneumatic or hydraulic cylinder.

[0050] In the assembly of the spot welding machine 100, the material receiving and unloading device 60 ensures that, for skirts 300 of different specifications (referring to ring diameter), the centers of the end plate 310 and the annular skirt 320 constituting the skirt 300 are aligned with the centers of the first pressing body 20 and the second pressing body 30. For example, the end plate 310, the annular skirt 320, the first pressing body 20, and the second pressing body 30 are arranged coaxially, thereby ensuring that the first pressing body 20 and the second pressing body 30 fit the end plate 310 and the annular skirt 320 onto the skirt. The reliability of the assembly is improved by using a spot welding mechanism 100b to perform circumferential spot welding 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 fitted together), thereby achieving the purpose of pre-fixing the end plate 310 and the annular skirt 320 that are fitted together, and preparing for the subsequent roll welding by the roll welding machine 200. Therefore, the top pressure between the end plate 310 and the annular skirt 320 that are fitted together can be greatly reduced, as well as the deformation of the annular skirt 320 caused by excessive top pressure.

[0051] like Figures 16 to 18 As shown, as an example, the roll welding machine 200 includes a support assembly 210, a rotary driver 220, a first-side follower-up pressure member 230, a sliding body 240, a sliding driver 250, a second-side follower-up pressure member 260, and a welding torch 270. The support assembly 210 includes a first support shaft 211 and a second support shaft 212 that are spaced apart from each other and parallel in the X-axis direction. The first support shaft 211 and the second support shaft 212 extend beyond the first-side follower-up pressure member 230 in the Y-axis direction, as shown in the diagram. Figure 19 As shown. The rotary actuator 220 is configured to drive the first support shaft 211 and the second support shaft 212 to rotate, so as to meet the need for both the first support shaft 211 and the second support shaft 212 to act as the active actuators and drive the spot-welded assembly 300' to rotate together; obviously, depending on actual needs, the rotary actuator 220 can also be designed to drive either the first support shaft 211 or the second support shaft 212 to rotate; alternatively, in Figure 22 In this example, the rotary actuator 220 is located below the first supporting shaft 211 and the second supporting shaft 212. This design provides more space for the arrangement of the first side follower pressing member 230 above the supporting assembly 210. Furthermore, the output end 221 of the rotary actuator 220, the first supporting shaft 211, and the second supporting shaft 212 are all equipped with sprockets 290e. The sprockets 290e are connected via chain drive to achieve synchronous rotation of the first supporting shaft 211 and the second supporting shaft 212 through the cooperation of the sprockets 290e and the chain. Obviously, depending on actual needs, pulleys and belts can also be used to replace the sprockets 290e and the chain; therefore, this is not strictly necessary. Figure 16, Figure 17 and Figure 22 The above is the limit.

[0052] The second-side follower-up pressing member 260 is arranged opposite to the first-side follower-up pressing member 230 in the Y-axis direction to meet the requirement that the second-side follower-up pressing member 260 and the first-side follower-up pressing member 230 jointly press the spot-welded assembly 300' in the Y-axis direction. The second-side follower-up pressing member 260 and the welding torch 270 are both mounted on the sliding body 240 to meet the requirement that the second-side follower-up pressing member 260 and the welding torch 270 slide along the sliding body 240. The sliding body 240 can be reciprocated along the Y-axis direction, and the sliding actuator 250 is configured to drive the sliding body 240 to slide closer to or away from the supporting assembly 210.

[0053] Therefore, during the roll welding process, the sliding actuator 250, through the sliding body 240, causes the second-side follower pressing member 260 and the first-side follower pressing member 230 to press the spot-welded assembly 300' supported by the support component 210 together in the Y-axis direction; then, the rotation actuator 220 drives the first support shaft 211 and the second support shaft 212 to rotate synchronously, and the synchronously rotating first support shaft 211 and the second support shaft 212 together drive the spot-welded assembly 300' to rotate together, so that the welding gun 270 welds a continuous or discontinuous roll weld structure 340 between the end plate 310 and the annular skirt 320 of the assembly 300', to obtain Figure 25 The skirt panel 300 is shown. For a more detailed description of the structure of the roll welding machine 200, please see below.

[0054] like Figures 16 to 18 and Figures 23 to 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. A second-side follower-up pressure member 260 is mounted on the side of the vertical plate 242 facing the first-side follower-up pressure member 230. A clearance space 2421 is also provided through the vertical plate 242, in which the welding torch 270 is placed. This design makes the assembly of the second-side follower-up pressure member 260 on the sliding body 240 more compact, and also allows the vertical plate 242 to provide a barrier function during roll welding, preventing welding sparks from splashing onto the X-axis transfer module 290a, Y-axis transfer module 290c, and Z-axis transfer module 290b described below. Specifically, in Figure 17 and Figure 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 spaced apart. The lower ends 2611 (2621) of the first follower pressing shaft 261 and the second follower pressing shaft 262 are close to each other. The welding torch 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. This design allows the second-side follower pressing member 260 to be compatible with roll welding operations of assemblies 300' of different sizes (referring to radial dimensions), thereby improving the versatility of the roll welding machine 200.

[0055] like Figure 23 and Figure 24 As shown, as an example, the roll welding machine 200 also includes a fixed base 280 located directly below the horizontal base 241. The horizontal base 241 is slidably mounted 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. The fixed base 280 is provided with a bracket 281 that is higher than the horizontal base 241 in the Z-axis direction, and the sliding actuator 250 is mounted on the bracket 281. At this time, the side of the vertical plate 242 facing away from the first side follower pressing member 230 is arranged opposite to the sliding actuator 250, and the output end of the sliding actuator 250 is assembled and connected to the horizontal base 241. See the state below. Figure 23 As shown; this design offers the advantage of a more compact structure compared to arranging the sliding actuator 250 between the upright plate 242 and the support assembly 210. Specifically, in Figure 23 and Figure 24 As an example, the slide actuator 250 may be, but is not limited to, a pneumatic or hydraulic cylinder, so that the slide body 240 can quickly switch between two extreme positions, thereby improving the efficiency of the roll welding machine 200.

[0056] like Figures 16 to 18 and Figures 23 to 24 As shown, as an example, the roll welding machine 200 also includes an X-axis transfer module 290a mounted on a 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. The welding torch 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 torch 270 can be precisely adjusted through 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 assemblies 300'. Specifically, in Figure 23As an example, the output end 293 of the Y-axis transfer module 290c is connected to an L-shaped adapter 290d. 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 torch 270 is mounted on the second extension section 295. (See attached diagram). Figure 23 As shown; therefore, by means of the L-shaped adapter 290d, the welding torch 270 is staggered from the Y-axis transfer module 290c in the Z-axis direction. For example, as an example, the X-axis transfer module 290a, Y-axis transfer module 290c and Z-axis transfer module 290b can all be structures composed of a motor, a lead screw and a lead nut, but are not limited thereto.

[0057] like Figures 19 to 20 As shown, as an example, the roll welding machine 200 also includes carbon brushes 290f positioned in contact directly above the first support shaft 211 and the second support shaft 212. Two first-side follower pressing members 230 are provided at the center between the first support shaft 211 and the second support shaft 212; two first-side follower pressing members 230 are also provided between the carbon brushes 290f, close to each carbon brush 290f; and six first-side follower pressing members 230 are arranged in an inverted "V" shape above the carbon brushes 290f. Specifically, as an example, the first-side follower pressing members 230 are omnidirectional balls to effectively reduce the frictional resistance between the first-side follower pressing members 230 and the end plate 310.

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

[0059] The welding process of the roll welding machine 300 is as follows: the transfer robot 400 takes the spot-welded assembly 300' from the transfer receiving mechanism 600 and places it on the first supporting shaft 211 and the second supporting shaft 212. 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 towards the first follower pressing member 230 until the second side follower pressing member 260 presses against the annular part of the assembly 300'. The welding torch 270 presses the assembly 300' together with the first side follower pressing member 330 on the skirt 320 in the Y-axis direction, while the welding torch 270 is located inside the annular skirt 320 of the assembly 300' at this time; then, the rotation driver 220 drives the first support shaft 211 and / or the second support shaft 212 to rotate, thereby driving the spot-welded assembly 300' to rotate together, thus realizing the purpose of circumferential roll welding between the end plate 310 and the annular skirt 320 in the assembly 300' by the welding torch 70, thereby improving the stability and reliability between the end plate 310 and the annular skirt 320 in the skirt 300.

[0060] Compared with the existing technology, by means of the cooperation of the assembly mechanism 100a, the spot welding mechanism 100b and the roll welding machine 200, the process of "firstly, the assembly mechanism 100a assembles the end plate 310 and the annular skirt 320 together to obtain the assembly 300', then the spot welding mechanism 100b performs circumferential spot welding between the end plate 310 and the annular skirt 320 in the assembly 300', and then the roll welding machine 200 performs circumferential roll welding on the spot-welded assembly 300'" can be greatly reduced. On the one hand, it can greatly reduce the top pressure between the assembled end plate 310 and the annular skirt 320, as well as the deformation of the annular skirt 320 caused by excessive top pressure. On the other hand, it can improve the stability and reliability between the end plate 310 and the annular skirt 320.

[0061] The above-disclosed examples are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall fall within the scope of the present utility model.
