Description

Technical Field

[0001] The invention relates to the technical field of inner drum welding, and in particular to an inner drum processing device for an industrial washing machine. Background Art

[0002] The inner drum of industrial washing machines usually uses stainless steel sheets. After stamping, the flat steel sheets are rolled into the initial shape of the inner drum by a rounding machine, and then welded into a cylindrical shape by laser welding. The inner drum is then flanging, ribbed and hemmed to improve its structural strength, durability and safety of use. Since the stainless steel sheet is thin, it has elasticity after rolling and bending. When welding, two operators are generally required to complete the abutment of the welding surface and the clamping of the welding part, which is troublesome. At the same time, due to the small gap between the support surface of the stainless steel sheet and the clamping mechanism, it is difficult to ensure that the welding part of the stainless steel sheet is centered by manual positioning, resulting in poor welding effect in the later stage.

[0003] For example, the patent application document with the publication number CN117862720A discloses a welding machine and a barrel ring processing method, the welding machine includes a machine body and a first pair of seam positioning components, the machine body is provided with a workbench and a positioning block, the workbench is provided with a welding groove, the two sides of the welding groove are provided with a first pressing plate and a second pressing plate, and the first pair of seam positioning components include a first pair of seam positioning pieces. The inner cylinder is placed on the positioning block and is located on the lower side of the workbench, the gap of the inner cylinder extends roughly along the center line of the welding groove, the first pair of seam positioning pieces move to the first working position, and then the end faces of the material heads on both sides of the gap of the inner cylinder are controlled to move to abut against the two side faces of the first pair of seam positioning pieces. Then, the second pressing plate is controlled to move downward, so that the second pressing plate presses the material head on the same side thereof, and the first pair of seam positioning pieces are controlled to move to the first waiting position; then the end face of the other material head is controlled to move to abut against the material head on the same side of the second pressing plate. In this way, the two material heads are connected and will not overlap, and the seam operation is completed.

[0004] The above technical solution can make the two material heads of the inner drum abut against each other to reduce the overlap of the two hoppers. However, since the two ends of the inner drum are not positioned, it is necessary to manually align the two ends of the two material heads when installing the inner drum on the positioning block. When the inner drum is installed manually, the center line of the weld will deviate from the center line of the welding groove by different distances. In this way, when aligning the weld, the distances adjusted on both sides of the inner drum are different. After welding one inner drum, the distances on both sides of the next inner drum need to be readjusted, which affects the welding efficiency. Therefore, it is necessary to develop an industrial washing machine inner drum processing equipment to solve the technical problem that the two ends of the two material heads need to be manually aligned when installing the inner drum and the center line of the weld deviates from the center line of the welding groove by different distances. Summary of the invention

[0005] In view of this, the present invention provides an industrial washing machine inner drum processing device to solve the technical problems that the two ends of the two material heads need to be manually aligned when installing the inner drum and the center line of the weld is offset by a different distance from the center line of the welding groove.

[0006] In order to solve the above technical problems, the present invention provides an industrial washing machine inner drum processing equipment, comprising a support seat, a pressure plate mechanism, a push plate mechanism and a welding mechanism arranged on the support seat, the support seat having a bottom plate and a side plate, the pressure plate mechanism comprising a pressure plate assembly and a pressure column arranged on one side of the pressure plate assembly, the axis of the pressure column being perpendicular to the bottom plate, a card slot is provided on the side of the pressure column close to the pressure plate assembly along the axis direction, an alignment block 1 is slidably connected in the card slot, an arc groove is provided on the end of the pressure column away from the card slot along the axis direction, a rotating shaft that can drive the material head of the inner drum to rotate is rotatably installed in the arc groove, a motor that can drive the rotating shaft to rotate is installed above the pressure column, and a photoelectric sensor that can detect the weld of the inner drum is installed on the side plate;

[0007] The pressing plate assembly includes a pressing plate 1 and a pressing plate 2 which are slidably arranged on the bottom plate, and a first linear driver which drives the pressing plate 1 and the pressing plate 2 to move horizontally; the first linear driver drives the pressing plate 2 to move and drives the alignment block 1 to reset;

[0008] The push plate mechanism includes a push plate 1 arranged on an end of the base plate away from the pressure-bearing column, and push plates 2 and 3 arranged on both sides of the push plate 1; the push plate 1 is driven by a second linear driver installed on the side plate, and the push plates 2 and 3 are driven by a driving assembly installed on the base plate; a pressure block is elastically connected to one end of the base plate away from the pressure-bearing column, and a connecting rod is fixedly connected between the pressure block and the alignment block 1; the second linear driver drives the push plate 1 to move and unlocks the pressure block, so that the pressure block and the connecting rod drive the alignment block 1 to move.

[0009] By adopting the above technical solution, the inner cylinder to be welded is placed on the bottom plate, and the inner cylinder is located between the push plate 1 and the rotating shaft. Since the bottom end of the inner cylinder contacts the bottom plate, the two ends of the inner cylinder can be made flush without manual alignment. Since the inner cylinder is located between the rotating shaft and the push plate 1, the placement space of the inner cylinder is reduced relative to that between the pressure plate assembly and the push plate 1, and the periphery of the inner cylinder is respectively in contact with the rotating shaft, the push plate 1, the push plate 2 and the push plate 3. The photoelectric sensor detects the position of the weld. When the center line of the weld deviates from the middle part of the arc groove, the motor drives the rotating shaft to rotate, so that the rotating shaft drives the material head of the inner cylinder to rotate until the weld is located in the middle part of the arc groove, thereby realizing the pre-alignment of the weld. Then, the position on the inner cylinder opposite to the weld is fixed, so that the two material heads of the inner cylinder are respectively located between the pressure plate 1 and the pressure-bearing column and between the pressure plate 2 and the pressure-bearing column, and the second linear actuator is started, and the second linear actuator drives the push plate 1 to move toward one end close to the inner cylinder. At the same time, the push plate 1 is disengaged from the pressure block, so that the pressure block is unlocked, and the pressure block drives the connecting rod and the alignment block 1 to move under the elastic action, so that the alignment block 1 moves in the direction away from the inner cylinder, and the driving component drives the push plate 3 to move in the direction close to the inner cylinder, so that the material head close to one end of the pressure plate 2 contacts the edge of the alignment block 1, and the first linear actuator is started to make the pressure plate 2 press the material head at this end; at the same time, the pressure plate 2 drives the alignment block 1 to reset, and the driving component drives the push plate 2 to move in the direction close to the inner cylinder, so that the material head close to one end of the pressure plate 1 abuts against the material head at the other end, and the first linear actuator drives the pressure plate 1 to press the material head at this end, so that the alignment of the weld is achieved, and then the welding mechanism welds the weld. The bottom end of the inner cylinder of the present invention contacts the bottom plate, and the two ends of the inner cylinder can be made flush without manual alignment. When aligning the weld, the weld is pre-aligned first to reduce the distance that the center line of the weld deviates from the center line of the weld groove, which is beneficial for adjusting the push plates 2 and 3 on both sides of the inner cylinder to an equal distance. When welding the next inner cylinder of the same size, there is no need to readjust the moving distance of the push plates 2 and 3, which is beneficial for improving the welding efficiency.

[0010] Preferably, pressure plate 1 and pressure plate 2 are located on both sides of the slot, the sides facing each other are provided with inclined surfaces and a welding groove is left between pressure plate 1 and pressure plate 2, and gaps are left between pressure plate 1 and pressure plate 2 and the pressure-bearing column to allow two material heads of the inner cylinder to pass through.

[0011] By adopting the above technical solution, before aligning the weld, the two material heads of the inner tube are first located in the gap to preliminarily position the inner tube. Both the first and second pressing plates are provided with inclined surfaces and a welding groove is left between the two, so that after the weld is aligned, the welding mechanism can weld the weld.

[0012] Preferably, an alignment block 2 is fixedly installed in the slot and abuts against the alignment block 1, the pressure plate 1 is close to the alignment block 1, and the pressure plate 2 is close to the alignment block 2.

[0013] By adopting the above technical solution, the welding seam is located between the alignment block 1 and the alignment block 2. After the alignment block 1 is reset, it is flush with the end surface of the alignment block 2, which is convenient for welding.

[0014] Preferably, a hydraulic chamber 1 is provided at the lower part of the slot, and sealing blocks 1 and 2 are elastically connected on both sides of the hydraulic chamber 1. Sealing block 2 is fixedly connected to pressure plate 2. Sealing block 1 is located at one end of alignment block 1 and can push alignment block 1 to reset.

[0015] By adopting the above technical solution, after the material head near one end of the pressure plate 2 is aligned with the alignment block 1, the first linear driver drives the pressure plate 2 to press the material head. At the same time, the pressure plate 2 drives the sealing block 2 to move toward the side close to the hydraulic chamber 1, so that the oil pressure in the hydraulic chamber 1 increases, and then pushes the sealing block 2 to move away from the hydraulic chamber 1, and then drives the alignment block 1 to move toward the side close to the inner cylinder, so that the alignment block 1 is reset, which makes it easier for the pressure plate 1 to press the material head near the end of the pressure plate 1, thereby realizing the alignment of the weld.

[0016] Preferably, the push plate 2 is arranged on a side close to the pressure plate 1, and the driving assembly includes a third linear driver for driving the push plate 2 to move.

[0017] By adopting the above technical solution, after the pressure plate 2 presses the material head near one end of the pressure plate 2, the alignment block 1 is reset, and the third linear drive drives the push plate 2 to move toward the direction close to the inner cylinder so that the material head near the end of the pressure plate 1 abuts against the material head near the end of the pressure plate 2, thereby facilitating the alignment of the weld.

[0018] Preferably, push plate three is arranged on a side close to pressure plate two, and the drive assembly also includes hydraulic chamber two and hydraulic chamber three arranged on the side plate, and a hydraulic pipe connected between hydraulic chamber two and hydraulic chamber three, the end of hydraulic chamber two is elastically connected with a plug, one side of push plate one is fixedly connected with a trigger member for triggering the movement of the plug, and a sealing block three is elastically connected in hydraulic chamber three, and sealing block three is fixedly connected to push plate three.

[0019] By adopting the above technical solution, push plate one moves toward one end of the inner cylinder, and when the trigger member contacts the plug, it pushes the plug to move toward the direction close to hydraulic chamber two, thereby increasing the oil pressure in hydraulic chamber two, and the hydraulic oil flows from hydraulic chamber two to hydraulic chamber three through the hydraulic pipe, thereby increasing the oil pressure in hydraulic chamber three, and the oil pressure pushes sealing block three to move in the direction away from hydraulic chamber three, thereby causing push plate three to move toward the direction close to the inner cylinder.

[0020] Preferably, the push plate 1 has two inclined surfaces and one plane, and the two inclined surfaces are located on both sides of the plane, so that the two inclined surfaces and the plane are in contact with the inner cylinder.

[0021] By adopting the above technical solution, the two inclined surfaces and the one plane are in contact with the inner cylinder, which increases the contact area between the push plate 1 and the inner cylinder, and is conducive to keeping the inner cylinder moving in a circular state.

[0022] Preferably, the heights of the push plate 1, the push plate 2 and the push plate 3 are all greater than half the height of the inner cylinder.

[0023] By adopting the above technical solution, after the inner cylinder is placed on the bottom plate, it is helpful to keep the side surface of the inner cylinder in a vertical state.

[0024] The beneficial effects of the above technical solution of the present invention are as follows:

[0025] 1. The bottom end of the inner tube of the present invention contacts the bottom plate, and the two ends of the inner tube can be made flush without manual alignment. When aligning the weld, the weld is pre-aligned first to reduce the distance that the center line of the weld deviates from the center line of the welding groove, which is conducive to adjusting the push plate 2 and the push plate 3 on both sides of the inner tube to an equal distance. When welding the next inner tube of the same size, there is no need to readjust the moving distance of the push plate 2 and the push plate 3, which is conducive to improving the welding efficiency.

[0026] 2. The pressing plate 2 of the present invention can drive the alignment block 1 to reset while pressing the material head, so that the ends of the alignment plate 1 and the alignment plate 2 are flush, which is convenient for welding.

[0027] 3. The heights of the push plates 1, 2 and 3 of the present invention are all greater than half the height of the inner cylinder, which is beneficial for keeping the side of the inner cylinder in a vertical state after the inner cylinder is placed on the bottom plate.

DETAILED DESCRIPTION

[0039] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be combined with the embodiments of the present invention. Figure 1-Figure 10 , the technical scheme of the embodiment of the present invention is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0040] Example

[0041] This embodiment provides an industrial washing machine inner drum processing equipment, such as Figure 1 As shown, it includes a support seat 1, a pressing plate mechanism 2, a pushing plate mechanism 3 and a welding mechanism 5.

[0042] like Figure 1 As shown, the support seat 1 has a bottom plate 11 and side plates 12. The side plates 12 are arranged around the bottom plate 11. The bottom plate 11 is used to place the inner cylinder 4, and the side plates 12 are used to install the pressing plate mechanism 2, the pushing plate mechanism 3 and the welding mechanism 5.

[0043] like Figure 1 As shown, the pressure plate mechanism 2 includes a pressure plate assembly 21 and a pressure column 22 .

[0044] like Figure 1 As shown, the pressure plate assembly 21 includes a pressure plate 1 211 , a pressure plate 212 and a first linear drive 213 .

[0045] like Figure 1 and Figure 4 As shown, the first pressing plate 211 and the second pressing plate 212 are both slidably arranged on the bottom plate 11, the first pressing plate 211 and the second pressing plate 212 are arranged in parallel and coplanar, the first pressing plate 211 and the second pressing plate 212 have inclined surfaces on their facing sides, and a welding groove 214 is left between the first pressing plate 211 and the second pressing plate 212. The inclined surface slopes downward from the side of the first pressing plate 211 and the second pressing plate 212 away from the inner cylinder 4 to the side close to the inner cylinder 4.

[0046] like Figure 1 As shown, two first linear drivers 213 are provided, both fixedly mounted on the side plate 12 , and respectively drive the first pressing plate 211 and the second pressing plate 212 to move away from or towards the inner cylinder 4 .

[0047] like Figure 2 and Figure 3 As shown, the pressure column 22 is fixedly arranged on the bottom plate 11 near the pressure plate 1 211 and the pressure plate 2 212, and there are gaps between the pressure column 22 and the pressure plate 1 211 and the pressure plate 2 212, so that the two material heads 411 of the inner tube 4 can pass through. The axis of the pressure column 22 extends in the up-down direction. A slot 222 is provided in the up-down direction at the position near the welding groove 214 on the pressure column 22, and an alignment block 1 25 and an alignment block 2 26 are provided in the slot 222. The alignment block 1 25 is slidably connected in the slot 222, and the alignment block 2 26 is fixedly connected in the slot 222. The end faces of the alignment block 1 25 and the alignment block 2 26 near the welding groove 214 are flush, and the alignment block 1 25 and the alignment block 2 26 are in contact. The pressure plate 1 211 is close to the alignment block 1 25, and the pressure plate 2 212 is close to the alignment block 2 26.

[0048] like Figure 6 and Figure 7 As shown, a hydraulic chamber 27 is provided at the lower portion of the slot 222, and sealing blocks 271 and 272 are elastically connected on both sides of the hydraulic chamber 27. The sealing block 272 is fixedly connected to the pressure plate 212, and the sealing block 271 is located at one end of the alignment block 25 and can push the alignment block 25 to reset.

[0049] like Figure 1 and Figure 3As shown, an arc groove 221 is provided on one end of the pressure column 22 away from the card slot 222 in the up-down direction, and a rotating shaft 23 capable of driving the material head 411 of the inner cylinder 4 to rotate is rotatably installed in the arc groove 221, and the transmission shaft extends out of the edge of the pressure column 22. A motor 24 capable of driving the rotating shaft 23 to rotate is installed above the pressure column 22, and a photoelectric sensor 28 capable of detecting the weld of the inner cylinder 4 is installed on the side plate 12. A controller is connected to the motor 24, and the photoelectric sensor 28 and the controller are connected through a wireless communication module line.

[0050] like Figure 1 and Figure 3 As shown, the inner cylinder 4 to be welded is placed on the bottom plate 11, and the inner cylinder 4 is located between the push plate mechanism 3 and the rotating shaft 23. Since the bottom end of the inner cylinder 4 contacts the bottom plate 11, the two ends of the inner cylinder 4 can be made flush without manual alignment. Since the inner cylinder 4 is located between the rotating shaft 23 and the push plate mechanism 3, the head 411 of the inner cylinder 4 contacts the rotating shaft 23, and the photoelectric sensor 28 detects the position of the weld. When the center line of the weld deviates from the middle part of the arc groove 221, the controller controls the motor 24 to rotate, and the motor 24 drives the rotating shaft 23 to rotate, so that the rotating shaft 23 drives the head 411 of the inner cylinder 4 to rotate until the weld is located in the middle part of the arc groove 221, so as to achieve pre-alignment of the weld. The motor 24 can drive the rotating shaft 23 to rotate forward and reverse, so as to be suitable for the center line of the weld deviating from any side of the middle part of the arc groove 221. For example, when the center line of the weld deviates from the left side of the middle part of the arc groove 221 , the motor 24 drives the rotating shaft 23 to rotate counterclockwise, so that the rotating shaft 23 drives the material head 411 to move rightward until the center line of the weld is located in the middle part of the arc groove 221 .

[0051] like Figure 2 As shown, the push plate mechanism 3 includes a push plate 1 31 , a push plate 2 32 and a push plate 3 33 .

[0052] like Figure 4-Figure 6As shown, the push plate 1 31 is slidably arranged on the end of the bottom plate 11 away from the pressure column 22. The push plate 1 31 has two inclined surfaces and a plane. The two inclined surfaces are located on both sides of a plane so that the two inclined surfaces and the plane are in contact with the inner cylinder 4. The push plate 1 31 is driven by a second linear actuator 34 installed on the side plate 12. A pressure block 36 is elastically connected to the lower part of the bottom plate 11 near the push plate 1 31, and a connecting rod 361 is fixedly connected between the pressure block 36 and the alignment block 1 25. In the initial position, the push plate 1 31 presses the pressure block 36, and the end surfaces of the alignment block 1 25 and the alignment block 2 26 are flush. When the second linear actuator 34 drives the push plate 1 31 to move toward the end close to the inner cylinder 4, the push plate 1 31 and the pressure block 36 are disengaged, so that the pressure block 36 is unlocked, and the pressure block 36 and the connecting rod 361 drive the alignment block 1 25 to move toward the end away from the inner cylinder 4, so that the material head 411 of the inner cylinder 4 abuts against the edge of the alignment block 1 25, so as to realize the alignment of the weld. The first linear actuator 213, the second linear actuator 34 and the third linear actuator 35 in this embodiment are all one of a cylinder or a hydraulic cylinder.

[0053] like Figure 2 As shown, the push plate 2 32 and the push plate 3 33 are both slidably mounted on the bottom plate 11, and are respectively located on both sides of the push plate 1 31. Among them, the push plate 2 32 is arranged on a side close to the pressure plate 1 211, and the push plate 2 32 is driven by a third linear actuator 35 fixedly mounted on the side plate 12.

[0054] like Figure 8-Figure 10 As shown, the push plate 3 33 is arranged on a side close to the pressure plate 2 212, and a hydraulic chamber 2 37 and a hydraulic chamber 3 38 are installed on the side plate 12 close to the push plate 3 33, and a hydraulic pipe 39 is connected between the hydraulic chamber 2 37 and the hydraulic chamber 3 38. In this embodiment, the hydraulic chamber 1 27, the hydraulic chamber 2 37 and the hydraulic chamber 3 38 are all filled with hydraulic oil. The end of the hydraulic chamber 2 37 is elastically connected with a plug 371, and a triggering member 311 for triggering the plug 371 to move is fixedly connected to the side of the push plate 1 31 close to the push plate 3 33, and a sealing block 381 is elastically connected in the hydraulic chamber 3 38, and the sealing block 381 is fixedly connected to the push plate 3 33.

[0055] like Figure 8-Figure 10 As shown, the push plate 1 31 moves toward one end close to the inner cylinder 4. When the trigger member 311 contacts the plug 371, the plug 371 is pushed to move toward the direction close to the hydraulic chamber 2 37, thereby increasing the oil pressure in the hydraulic chamber 2 37. The hydraulic oil flows from the hydraulic chamber 2 37 to the hydraulic chamber 3 38 through the hydraulic pipe 39, thereby increasing the oil pressure in the hydraulic chamber 3 38. The oil pressure pushes the sealing block 3 381 to move away from the hydraulic chamber 3 38, thereby causing the push plate 3 33 to move toward the direction close to the inner cylinder 4.

[0056] like Figure 1 and Figure 2As shown, the heights of the push plate 1 31 , the push plate 2 32 and the push plate 3 33 are all greater than half the height of the inner cylinder 4 . After the inner cylinder 4 is placed on the bottom plate 11 , it is helpful to keep the side of the inner cylinder 4 in a vertical state.

[0057] like Figure 1 As shown, since the inner cylinder 4 is located between the rotating shaft 23 and the push plate 1 31, the placement space of the inner cylinder 4 is reduced relative to that between the pressure plate assembly 21 and the push plate 1 31, and the periphery of the inner cylinder 4 is respectively in contact with the rotating shaft 23, the push plate 1 31, the push plate 2 32 and the push plate 3 33. When the photoelectric sensor 28 detects that the center line of the weld deviates from the middle part of the arc groove 221, the motor 24 drives the rotating shaft 23 to rotate, so that the rotating shaft 23 drives the material head 411 of the inner cylinder 4 to rotate until the weld is located in the middle part of the arc groove 221, thereby realizing the pre-alignment of the weld. Then, as shown in FIG. Figure 2 and Figure 3 As shown, the portion of the inner tube 4 opposite to the weld is fixed so that the two material heads 411 of the inner tube 4 are respectively located between the first pressing plate 211 and the pressure column 22 and between the second pressing plate 212 and the pressure column 22. Figure 4-Figure 6 As shown, the second linear actuator 34 is started, and the second linear actuator 34 drives the push plate 31 to move toward the end close to the inner cylinder 4. At the same time, the push plate 31 is separated from the pressing block 36, so that the pressing block 36 is unlocked. The pressing block 36 drives the connecting rod 361 and the alignment block 25 to move under the elastic action, so that the alignment block 25 moves away from the inner cylinder 4. Figure 9-10 As shown, when the trigger member 311 contacts the plug 371, the plug 371 is pushed to move toward the direction close to the hydraulic chamber 2 37, thereby increasing the oil pressure in the hydraulic chamber 2 37, and the hydraulic oil flows from the hydraulic chamber 2 37 to the hydraulic chamber 3 38 through the hydraulic pipe 39, thereby increasing the oil pressure in the hydraulic chamber 3 38, and the oil pressure pushes the sealing block 3 381 to move away from the hydraulic chamber 3 38, thereby causing the push plate 3 33 to move toward the direction close to the inner cylinder 4, as shown in FIG. Figure 2 and Figure 3As shown, the material head 411 near one end of the second pressing plate 212 contacts the edge of the first alignment block 25, and the first linear driver 213 is started to make the second pressing plate 212 press the material head 411 at this end; at the same time, the second pressing plate 212 drives the first alignment block 25 to reset, and the end surfaces of the first alignment block 25 and the second alignment block 26 are flush. The third linear driver 35 drives the second push plate 32 to move toward the inner cylinder 4, so that the material head 411 near one end of the first pressing plate 211 abuts against the material head 411 at the other end, and the first linear driver 213 drives the first pressing plate 211 to press the material head 411 at this end, so as to achieve the alignment of the weld. When aligning the weld, pre-align the weld first to reduce the distance that the center line of the weld deviates from the center line of the weld groove 214, which is beneficial to adjust the push plates 2 32 and 33 on both sides of the inner cylinder 4 to an equal distance. When welding the next inner cylinder 4 of the same size, there is no need to readjust the moving distance of the push plates 2 32 and 33, which is beneficial to improving the welding efficiency.

[0058] like Figure 1 As shown, the welding mechanism 5 is arranged on the side plate 12 near the welding groove 214, which is a prior art and will not be described in detail. After the two material heads 411 of the inner tube 4 are aligned, the welding mechanism 5 welds the weld.

[0059] The method for using the industrial washing machine inner drum 4 processing equipment of this embodiment comprises the following steps:

[0060] Step 1: Place the inner cylinder 4 to be welded on the bottom plate 11, and the inner cylinder 4 is located between the push plate 1 31 and the rotating shaft 23. Since the bottom end of the inner cylinder 4 is in contact with the bottom plate 11, it is possible to ensure that both ends of the inner cylinder 4 are flush without manual alignment;

[0061] Step 2: The photoelectric sensor 28 detects the position of the weld. When the photoelectric sensor 28 detects that the center line of the weld deviates from the middle part of the arc groove 221, the controller controls the motor 24 to rotate, and the motor 24 drives the rotating shaft 23 to rotate, so that the rotating shaft 23 drives the material head 411 of the inner cylinder 4 to rotate until the weld is located in the middle part of the arc groove 221, thereby realizing the pre-alignment of the weld.

[0062] Step 3: fix the part of the inner tube 4 opposite to the weld so that the two material heads 411 of the inner tube 4 are respectively located between the first pressing plate 211 and the pressure column 22 and between the second pressing plate 212 and the pressure column 22, and preliminarily fix the position of the inner tube 4;

[0063] Step 4: Start the second linear actuator 34, which drives the push plate 1 31 to move toward the end close to the inner cylinder 4. At the same time, the push plate 1 31 is disengaged from the pressure block 36, so that the pressure block 36 is unlocked. The pressure block 36 drives the connecting rod 361 and the alignment block 1 25 to move under the action of elasticity, so that the alignment block 1 25 moves in the direction away from the inner cylinder 4. When the trigger member 311 contacts the plug 371, the plug 371 is pushed to move in the direction close to the hydraulic chamber 2 37, thereby increasing the oil pressure in the hydraulic chamber 2 37. The hydraulic oil flows from the hydraulic chamber 2 37 to the hydraulic chamber 3 38 through the hydraulic pipe 39, thereby increasing the oil pressure in the hydraulic chamber 3 38. The oil pressure pushes the sealing block 381 to move in the direction away from the hydraulic chamber 3 38, thereby causing the push plate 3 33 to move in the direction close to the inner cylinder 4, so that the material head 411 near the end of the pressure plate 212 contacts the edge of the alignment block 1 25.

[0064] Step 5: Start the first linear actuator 213, so that the second pressing plate 212 presses the material head 411 at this end. At the same time, the second pressing plate 212 drives the alignment block 1 25 to reset, and the end surfaces of the alignment block 1 25 and the alignment block 2 26 are flush; the third linear actuator 35 drives the second pushing plate 32 to move toward the inner cylinder 4, so that the material head 411 near one end of the pressing plate 1 211 abuts against the material head 411 at the other end, and the first linear actuator 213 drives the pressing plate 1 211 to press the material head 411 at this end, so as to realize the alignment of the weld;

[0065] Step 6: Start the welding mechanism 5 to weld the weld.

[0066] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0067] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
