[0031] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0032] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes, and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions and technical features between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0033] The present invention provides the following embodiments:

[0034] Embodiment 1: The embodiment of the present invention provides a transformer oil tank production line with a multi-station flow, such as Figure 1-Figure 13 As shown, it includes a material conveying mechanism 1, which is used to convey the cut box plate materials. The rear end of the material conveying mechanism 1 is correspondingly connected to a bending mechanism 2, in which a bending shell 32 is rotatably installed, and the bending shell 32 is connected to a positioning assembly, and the positioning assembly is used to fix the head of the box plate material on the bending shell 32. An auxiliary mechanism is correspondingly arranged on the right side of the bending mechanism 2. The bending mechanism 2 bends the box plate material and sends the bent box plate material into the auxiliary mechanism for welding and leak testing. The auxiliary mechanism is correspondingly arranged in the auxiliary station, and the front side of the auxiliary station is correspondingly connected to a finished product conveying mechanism. The auxiliary mechanism sends the transformer oil tank that has passed the welding and leak testing into the finished product conveying mechanism, and the finished product conveying mechanism is connected to the paint spraying room 4.

[0035] The working principle of the above technical solution is:

[0036] When producing the oil tank, the cut box plate material is placed on the material conveying mechanism 1, and the box plate material is sent to the positioning component of the bending mechanism 2 through the material conveying mechanism 1. The positioning component first corrects the box plate material to prevent the box plate material from tilting in the horizontal direction during the transmission process of the material conveying mechanism 1, causing it to be in a tilted state when entering the bending mechanism 2. After the box plate material is corrected, the positioning component positions and fixes the head of the box plate material, and the bending shell 32 rotates to pull the box plate material into the bending mechanism 2. The bending mechanism 2 bends the box plate material and sends it to the auxiliary mechanism. The bent box plate material is welded in the auxiliary station to form a box wall, and then the box cover is welded at the upper end of the box wall, and the box bottom is welded at the lower end of the box wall to form a box body, and then the reinforcing ribs and related tank components are welded on the surface of the box body. The welding method can adopt the existing manual welding or robot welding method, as well as the box body before and after welding. Grinding and polishing can be done manually, which will not be described in detail in the present invention. After the box body welding process is completed to form the transformer oil tank, the auxiliary mechanism performs a leak test on the transformer oil tank. If the leak test is qualified, the auxiliary mechanism sends the qualified transformer oil tank to the finished product conveying mechanism, and the finished product conveying mechanism sends the transformer oil tank to the paint spraying room 4 for painting. The painting process adopts the existing transformer oil tank painting process, which will not be described in detail in the present invention. The multi-station flow transformer oil tank production line of the present invention links the bending, welding, leak test and painting in the transformer oil tank production process, and does not need to manually transfer the products processed by the bending, welding and leak test processes, thereby improving the production efficiency of the transformer oil tank and solving the problem that each process of the traditional transformer oil tank production is carried out independently, and the products after the corresponding process is processed need to be manually transferred to the next process for production and processing by the production team employees, which is time-consuming and labor-intensive, and restricts the production progress of the oil tank.

[0037] Embodiment 2: Based on embodiment 1, Figure 1-Figure 3 As shown, the material conveying mechanism 1 includes two base plates 10 distributed on the left and right, a plurality of conveying rollers 11 are evenly spaced between the two base plates 10 along the front-to-back direction, a sprocket 8 is connected to the left side of the plurality of conveying rollers 11, the sprockets 8 on the plurality of conveying rollers 11 are connected through chains 7, a guard plate 9 is provided on the right side of the sprocket 8, a plurality of through holes are evenly spaced along the front-to-back direction on the guard plate 9, the plurality of through holes are rotatably connected to the plurality of conveying rollers 11 in a one-to-one correspondence, the frontmost conveying roller 11 is fixedly connected to a motor shaft 6, the motor shaft 6 passes through the base plate 10 on the left side and is fixedly connected to a drive motor 5, the drive motor 5 is mounted on a fixed plate 1, and the fixed plate 1 is fixedly connected to the base plate 10 on the left side;

A paint blocking plate 13 is installed at the upper end between the left base plate 10 and the guard plate 9 in the finished product conveying mechanism.

When several sprockets 8 rotate synchronously, they drive several conveying rollers 11 to rotate, and when several conveying rollers 11 rotate, they can drive the box board materials to move. The setting of the guard plate 9 is used to separate the sprocket 8 and the chain 7 from the conveying area of ​​the conveying roller 11 to avoid interference between the chain 7 and the sprocket 8 and the conveyed box board materials. The setting of the paint blocking plate 13 can prevent paint from falling on the chain 7 and the sprocket 8 during the painting process, thereby affecting the service life of the chain 7 and the sprocket 8.

[0041] Embodiment 3: Based on embodiment 1, Figure 1-Figure 7 As shown, the bending mechanism 2 includes a mounting platform 18, which is fixedly arranged on the lower side of the rear end of the base plate 10 of the material conveying mechanism 1, and a support block 1 is fixedly arranged on the middle part of the left side of the mounting platform 18, and the support block 1 is rotatably connected to the support shaft 40, and the support shaft 40 is fixedly connected to the motor shaft 2, and the motor shaft 2 is fixedly connected to the drive motor 2 31, and the drive motor 2 31 is installed on the fixed plate 2, and the fixed plate 2 is fixedly connected to the support block 1, and the support shaft 40 is fixedly connected to the middle part of the bending shell 32, and an empty groove 54 is provided at the upper end of the bending shell 32, and a cover plate is provided at the upper end of the empty groove 54, and a U-shaped guide cavity 43 is provided at the left end of the bending shell 32, and the U-shaped guide cavity 43 and the empty groove 54 are connected left and right, and an opening 44 is provided at the lower end of the bending shell 32, and the empty groove 54 and the opening 44 are connected up and down;

[0042] The positioning assembly includes a guide block 53 slidably connected to the U-shaped guide cavity 43, the guide block 53 is rotatably connected to the sliding rod 52, the sliding rod 52 is slidably connected to the sliding cavity on the rotating block 51, the rotating block 51 is eccentrically connected to the left end of the disk 50 through a connecting rod, the disk 50 is fixedly connected to the support shaft 40, the end of the guide block 53 away from the sliding rod 52 is fixedly connected to the vertical section of the L-shaped traction plate 42, and the lower side of the empty slot 54 is rotatably provided with a threaded rod 47, the threaded sections on the left and right sides of the threaded rod 47 rotate in opposite directions, and the threaded sections on the left and right sides of the threaded rod 47 are respectively connected to the threaded block 4 8 threaded connection, the threaded block 48 passes through the opening and is fixedly connected to the correction block 45, the correction block 45 is slidably connected to the front end of the positioning block 49, the positioning block 49 is fixedly arranged on the rear side of the lower end of the bending shell 32, and the front end of the positioning block 49 is kept flush with the right end of the bending shell 32 along the up and down vertical directions, the middle cylindrical section of the threaded rod 47 is fixedly connected to the elliptical block 46, the right cylindrical section of the threaded rod 47 passes through the right end of the empty slot 54 and is fixedly connected to the external drive motor three 41, the drive motor three 41 is fixedly connected to the fixing plate three, and the fixing plate three is fixedly connected to the right end of the bending shell 32.

[0043] The working principle of the above technical solution is:

[0044] When placing the head of the box board material on the conveying roller 11 for conveying, it should be placed as close as possible to the middle side of the guard plate 9 and the right base plate 10. After the head of the box board material extends out of the conveying roller 11 on the rear side and enters the area corresponding to the mounting platform 18, the driving motor 2 31 drives the motor shaft 2 to rotate, the motor shaft 2 drives the support shaft 40 to rotate, the support shaft 40 drives the disc 50 to rotate, the disc 50 drives the rotating block 51 to rotate through the connecting rod, and the rotating block 51 drives the sliding rod 52 to move when it rotates. The sliding connection between the sliding cavity and the sliding rod 52 enables the sliding rod 52 to drive the guide block 53 to slide freely along the U-shaped guide cavity 43. The guide block 53 first drives the L-shaped traction plate 42 to move downward until the guide block 53 contacts the lower end of the U-shaped guide cavity 43. At this time, the L-shaped The upper end of the horizontal section of the traction plate 42 is slightly lower than the upper end of the conveying roller 11. The horizontal section of the L-shaped traction plate 42 supports the head of the box board material. Then, as the disc 50 continues to rotate, the guide block 53 slides back and forth along the U-shaped guide cavity 43, driving the L-shaped traction plate 42 to move backward. The speed of the drive motor 2 31 is controlled so that the speed at which the L-shaped traction plate 42 moves backward is the same as the speed at which the conveying roller 11 conveys the box board material, so that the L-shaped traction plate 42 drives the head of the box board material to move backward synchronously until the head of the box board material moves to the front end of the positioning block 49. After the head of the box board material can no longer move backward, the guide block 53 moves to the rear end of the U-shaped guide cavity 43 and starts to move upward. The guide block 53 drives the box board through the L-shaped traction plate 42 The head of the material moves upward, and when the L-shaped traction plate 42 moves upward, it cannot contact the positioning block 49, thereby driving the upper side of the head of the box board material to enter between the left and right correction blocks 45, and controlling the driving motor 2 31 to stop working. The thickness of the correction block 45 is less than the thickness of the box board material. At this time, the driving motor 3 41 is controlled to work, and the driving motor 3 41 drives the threaded rod 47 to rotate. When the threaded rod 47 rotates, it drives the threaded blocks 48 on the left and right sides to move in a direction close to each other. In this process, when the elliptical block 46 rotates, its protruding section cannot contact the box board material. The threaded block 48 drives the correction block 45 to move, and the correction block 45 squeezes and contacts the left and right ends of the box board material. In this process, the correction of the head of the box board material is completed. During the correction process, the drive motor three 41 should be controlled to control the threaded rod 47 to rotate according to a multiple of half a circle, and the pitch of the threaded rod 47 is small enough so that after the correction block 45 corrects the head of the box board material, the protruding section of the elliptical block 46 cannot extend out of the opening. The drive motor three 41 is controlled to stop working, and the drive motor two 31 is continued to be controlled to work, so that the L-shaped traction plate 42 drives the head of the box board material to continue to move upward until the head of the box board material contacts the lower end of the bending shell 32, so that the bending shell 32 and the L-shaped traction plate 42 clamp and fix the upper and lower ends of the head of the box board material. Since the thickness of the box board material is greater than the thickness of the correction block 45, the L-shaped traction plate 42 will not be squeezed and contacted with the correction block 45, and then the drive motor three 41 is controlled to work.The correction block 45 is driven to fix the left and right ends of the head of the box board material, thus completing the purpose of positioning and fixing the head of the box board material.

The rear end of the mounting plate 1 is fixedly connected with the fixed section of the electric telescopic rod 21, and the movable section of the electric telescopic rod 21 passes through the mounting plate 1 and is fixedly connected with the guide card block 2.

[0046] The working principle of the above technical solution is:

[0047] After the head of the box material is positioned and fixed, the driving motor 2 31 continues to work. At this time, since the L-shaped traction plate 42 cannot move upward, the rotating block 51, the sliding rod 52 and the guide block 53 remain fixed. At this time, the bending shell 32 rotates synchronously with the support shaft 40 and the disc 50 connected thereto. First, the bending shell 32 is controlled to rotate 90 degrees to make the bending shell 32 rotate to a vertical state, and then the electric telescopic rod 21 is controlled to extend. The electric telescopic rod 21 drives the pressing plate 2 39 and the bending head 2 55 to move toward the direction of the bending shell 32. The upper end of the pressing plate 2 39 rotates with the bending shell 32. The lower end of the L-shaped traction plate 42 is fitted when the pressing plate 2 is moved to a vertical state, the distance between the upper end of the bending head 2 55 and the lower end of the bending shell 32 when it is rotated to a vertical state is the same as the thickness of the box board material, the distance between the rear end of the front bending head 1 63 and the front end of the bending shell 32 when it is rotated to a vertical state is the same as the thickness of the box board material, and the distance between the front end of the rear bending head 1 63 and the rear end of the bending shell 32 when it is rotated to a vertical state is the same as the thickness of the box board material, so that with the movement of the pressing plate 2 39 and the bending head 2 55, the box board material is bent for the first time, and after the box board material is completed After the first bending, the bending shell 32 is controlled to rotate 180 degrees, and then the electric telescopic rod 133 on the front side is controlled to extend to drive the front pressure plate 134 and the front bending head 163 to move downward, and the front pressure plate 134 and the bending head 163 fix the edge of the box board material at the first bending, and then the electric telescopic rod 133 on the rear side is controlled to extend to drive the rear pressure plate 134 and the rear bending head 163 to move downward, and the box board material is bent for the second time, and finally the electric telescopic rod 21 is controlled to extend to drive the pressure plate 239 and the bending head 255 to move, and the box board material is bent for the third time. At this time, the upper end of the second pressing plate 39 is fitted with the lower end of the bending head 1 63 on the rear side to complete the bending process of the box plate material. The function of the pressing plate 1 34 and the pressing plate 2 39 is to press the box plate material on the surface of the bending shell 32 when bending the box plate material, so that the box plate material is bent with the bending shell 32 as the base block, and the inner wall size of the box formed after the box plate material is bent is the same as the outer wall size of the bending shell 32. The bending mechanism 2 of the present application is suitable for bending thin plates with a thickness of 4 mm or less. A rounded corner is set at the folding edge of the bending shell 32, and the rounded corner is the same as the bending angle of the box plate material;

[0048] Optionally, one end of the pressing plate 2 39 can be separately set from the bending head 2 55, specifically, the bending head 2 55 is distributed on the lower side of the pressing plate 2 39. At this time, there is a gap between the bending head 2 55 and the pressing plate 2 39. At this time, the connecting block 1 57 on the rear side is slidably connected to the pressing plate 2 39 along the front-to-back direction through a fixed block, and the connecting block 1 57 on the rear side is no longer connected to the bending head 2 55. Then, the electric telescopic rod 7 is fixedly installed on the mounting plate 1, and is fixedly connected to the bending head 2 55 through the movable section of the electric telescopic rod 7. The extension and contraction of the electric telescopic rod 7 drives the bending head 2 55 to move forward and backward. Optionally, the pressing plate 1 34 can be separately set from the bending head 1 63, specifically, a movable groove is set at the rear end of the pressing plate 1 34, and the electric telescopic rod 8 is fixedly installed on the front and rear sides of the top plate 35 respectively. The movable section of the electric telescopic rod 8 The movable section is fixedly connected to the bending head 63 through a movable groove, and the extension and retraction of the electric telescopic rod 8 drives the bending head 63 to move up and down. Through the separate driving of the pressing plate 2 39 and the bending head 2 55, and the separate driving of the pressing plate 1 34 and the bending head 1 63, the pressing plate 1 34 and the pressing plate 2 39 can first be used to press the box board material to fit on the bending shell 32, and then the bending head 2 55 and the bending head 1 63 can be controlled to move to bend the box board material, and the pressing plate 2 39 and the bending head 2 55 are driven separately, and the pressing plate 1 34 and the bending head 1 63 are driven separately. Compared with the joint driving of the pressing plate 2 39 and the bending head 2 55, the joint driving of the pressing plate 1 34 and the bending head 1 63 increases the cost, but the interference with the box board material is small, and the bending effect is good. The installation method of the bending head 2 55 and the bending head 1 63 can be selected according to the actual situation.

[0050] The bending mechanism 2 also includes an electric telescopic rod three respectively arranged on the front and rear sides of the upper end of the top plate 35, the electric telescopic rod three is distributed on the right side of the electric telescopic rod one 33, and the fixed section of the electric telescopic rod three is fixedly connected to the top plate 35, the movable section of the electric telescopic rod three penetrates the top plate 35 and is fixedly connected to the guide card block three 62, the guide card blocks three 62 on the front and rear sides are respectively slidably connected with the guide card channel one 61 on the upper end of the pressure plate one 34 on the front and rear sides, the rear end of the mounting plate one is fixedly connected with the fixed section of the electric telescopic rod four, the electric telescopic rod four is distributed on the right side of the electric telescopic rod two 21, the movable section of the electric telescopic rod four penetrates the mounting plate one and is fixedly connected with the guide card block four, the guide card block four is correspondingly slidably connected with the guide card channel two at the rear end of the pressure plate two 39, the guide card blocks three 62 on the front and rear sides and the guide card channel one 61 on the upper end of the pressure plate one 34 on the front and rear sides The card block four is correspondingly arranged on the upper side of the welding shell 14, the left end of the bending head 2 55 is slidably connected to the right end of the connecting block 1 57 on the rear side along the front-to-back direction, the upper left end of the connecting block 1 57 on the rear side is fixedly connected to the rear end of the U-shaped connecting plate 58, the front end of the U-shaped connecting plate 58 is fixedly connected to the connecting block 1 57 on the front side, the connecting blocks 1 57 on the front and rear sides are respectively slidably connected to the pressure plates 1 34 on the front and rear sides along the up-down direction, the front and rear ends of the U-shaped connecting plate 58 are respectively slidably connected to the sliding openings 59 on the side panels distributed front and back, the side panels distributed front and back are respectively arranged on the front and back parts of the left side of the mounting platform 18, the side panel on the rear side is fixedly connected to the fixed section of the electric telescopic rod 56, the movable section of the electric telescopic rod 56 passes through the side panel on the rear side and is fixedly connected to the lower left end of the connecting block 57 on the rear side.

[0051] The working principle of the above technical solution is:

[0052] The setting of the connecting block 1 57 guides the up and down movement of the pressing plate 1 34 and the forward and backward movement of the bending head 2 55 and the pressing plate 2 39, so as to avoid shaking of the bending head 1 63 and the bending head 2 55 when bending the box board material. After the bending of the box board material is completed, the electric telescopic rod 1 33 and the electric telescopic rod 2 21 on the front and rear sides are controlled to stop working, and the bending head 1 63, the bending head 2 55, the pressing plate 1 34 and the pressing plate 2 39 are kept in a tight state on the box board material. Then, the driving motor 3 41 and the driving motor 2 31 are controlled to work in reverse, so that the L-shaped traction plate 42 and the correction block 45 are separated from the contact with the head of the box board material. During the reverse operation of the driving motor 2 31, the protruding section of the elliptical block 46 extends out of the opening and pushes the head of the box board material out of the opening. The U-shaped connecting plate 58 is used to move the connecting block 57 on the front side to the right, and the connecting block 57 on the front side drives the connecting block 57 on the front side to move to the right synchronously. The sliding opening 59 guides the sliding of the U-shaped connecting plate 58. When the connecting blocks 57 on the front and rear sides move to the right, the pressure plates 34 on the front and rear sides, the bending heads 63 on the front and rear sides, the bending heads 55 and the pressure plates 39 on the front and rear sides are driven to move to the right. The sliding setting of the guide block 1 and the guide card track 61 guides the movement of the pressure plate 34, and the sliding setting of the guide block 2 and the guide card track 2 guides the movement of the pressure plate 39 The pressing plate 1 34 and the pressing plate 2 39 drive the box plate material in contact with the pressing plate to move to the right until the box plate material is sent to the welding shell 14. At this time, the guide card block 3 62 is slidably matched with the guide card path 1 61, and the guide card block 4 is slidably matched with the guide card path 2. The guide card block 1, the guide card block 2, the guide card block 3 62, the guide card block 4, the guide card path 1 61 and the guide card path 2 are all convexly configured, and the guide card block 1, the guide card block 2, the guide card block 3 62, and the guide card block 4 are completely identical in structure, and the guide card path 1 61 and the guide card path 2 are completely identical in structure, so that the cooperation of the guide card block 1, the guide card block 3 62 and the guide card path 1 61, and the cooperation of the guide card block 2, the guide card block 4 and the guide card path 2 can only be slidably matched along the front-back direction. The distance between block one and guide block three 62 is smaller than the length of guide card track one 61, and the distance between guide block two and guide block four is smaller than the length of guide card track two, so as to avoid the falling off phenomenon in the cooperation between guide block one, guide block three 62 and guide card track one 61, and the cooperation between guide block two, guide block four and guide card track two. The setting of electric telescopic rod three can adjust the up and down position of guide block three 62, so that guide block three 62 and guide block one always keep in the same horizontal plane, and the setting of electric telescopic rod four can adjust the up and down position of guide block four, so that guide block four and guide block two always keep in the same horizontal plane. Since the bending shell 32 rotates 270 degrees in the above-mentioned bending process of the box plate material, the bending shell 32 is in a vertical state.This ensures that the box plate material is delivered to the welding shell 14. At this time, the edge of the box plate material corresponding to the lower side of the left end of the bending shell 32 is the welding area, and then the welding area is welded to form the box wall.

[0053] Embodiment 6: Based on embodiment 5, Figure 1-Figure 9 As shown, the upper ends of the bending shell 32 and the welding shell 14 are respectively provided with limit assemblies, and the limit assemblies include limit blocks 37, and the limit blocks 37 are respectively arranged at the upper ends of the bending shell 32 and the welding shell 14, and the limit blocks 37 corresponding to the upper ends of the bending shell 32 and the limit blocks 37 corresponding to the upper ends of the welding shell 14 are different in size, and the lower end of the limit block 37 corresponding to the upper end of the bending shell 32 is evenly spaced along the front-to-back direction. The lower end of the limit block 37 corresponding to the upper end of the welding shell 14 is evenly spaced along the left-to-right direction. The upper end of the limit block 37 is fixedly connected to the sliding shaft, and the sliding shaft passes through the top plate 35 and is fixedly connected to the stop block 36. A spring 38 is fixedly provided between the upper end of the limit block 37 and the top plate 35, and the spring 38 is sleeved on the sliding shaft.

[0054] The working principle of the above technical solution is:

[0055] Under the action of the spring 38, the limit roller 60 can fit with the bending shell 32 and the welding shell 14. When the bending shell 32 rotates, the limit roller 60 can be pushed to move upward, and the limit roller 60 drives the sliding shaft to move upward through the limit block 37, and the sliding shaft drives the stop block 36 to move, and the spring 38 is compressed. The elastic force of the spring 38 is large enough, so that when the drive motor 2 31 works, it first drives the L-shaped traction plate 42 to move. At this time, the bending shell 32 cannot rotate until the L-shaped traction plate 42 presses the head of the box plate material on the bending shell 32, and when the pressing force is large enough, the drive motor 2 31 can work to drive the L-shaped traction plate 42 and the bending shell 32 to rotate synchronously. The lower end of the limit block 37 corresponding to the upper end of the bending shell 32 is evenly spaced along the left and right directions. A plurality of limit rollers 60 are arranged at intervals. If the bending shell 32 drives the box plate material to pass through the limit roller 60, the limit roller 60 can make the box plate material pass through the limit roller 60 under the elastic action of the spring 38. The plate material is attached to the bending shell 32, which limits the plate material when it moves with the bending shell 32, facilitating the subsequent bending steps of the plate material, and the plate material can drive the limit roller 60 to rotate when passing through the limit roller 60, to avoid excessive friction between the limit roller 60 and the plate material, which causes the head of the plate material to separate from the positioning component, and a plurality of limit rollers 60 are evenly spaced in the front-to-back direction at the lower end of the limit block 37 corresponding to the upper end of the welding shell 14. When the plate material moves to the right, the limit roller 60 can rotate and guide the plate material, and the plurality of limit rollers 60 can press the upper end of the plate material against the upper end of the welding shell 14. When moving to the right, the sum of the friction between the limit roller 60 corresponding to the upper end of the bending shell 32 and the plate material and the friction between the plate material and the bending shell 32 is less than the friction between the pressing plate 1 34 and the pressing plate 2 39 and the plate material.

[0056] Embodiment 7: Based on embodiment 5, Figure 1-Figure 13As shown, the auxiliary station includes an auxiliary table 3, which is fixedly arranged at the right end of the mounting table 18, a finished product conveying mechanism is arranged at the front end of the auxiliary table 3, an operating table 12 is arranged between the auxiliary table 3 and the right side base plate 10 of the material conveying mechanism 1, and the auxiliary mechanism also includes two slide rails 24 fixedly arranged at the lower side of the upper end of the auxiliary table 3, the two slide rails 24 are slidably connected with two sliders 25, and the two sliders 25 are symmetrically arranged at the left and right sides of the upper end of the transmission block 26, the transmission block 26 is fixedly connected with the upper end of the mounting plate 27, and the upper end array of the mounting plate 27 is provided with a plurality of electric telescopic rods 6 23, and the electric The fixed section of the telescopic rod six 23 is fixedly connected to the mounting plate two 27, the threaded hole at the rear end of the transmission block 26 is threadedly connected to the threaded section of the lead screw, the cylindrical section of the lead screw passes through the rear end of the auxiliary table 3 and is fixedly connected to the motor two 22, the motor two 22 is fixedly connected to the rear end of the auxiliary table 3, the movable section of the electric telescopic rod six 23 passes through the mounting plate two 27 and is fixedly connected to the mounting plate three through a number of connecting blocks two 28, a power pump two 29 is fixedly provided on the mounting plate three, the power pump two 29 is connected to the suction cup 30, the suction cup 30 is fixedly arranged in the middle of the lower end of the mounting plate three, and the suction cup 30 is arranged corresponding to the welding shell 14.

[0057] The working principle of the above technical solution is:

[0058] The setting of the operating table 12 is convenient for setting up a welding robot or manually welding the welding area of ​​the box plate material on the operating table 12. After the welding is completed, the pressure plates 1 34 and 2 39 on the front and rear sides are controlled to separate from the contact with the box plate material, and the motor 1 20 is controlled to work. The motor 1 20 drives the rotating shaft 19 to rotate, and the rotating shaft 19 drives the welding shell 14 to rotate 90 degrees to the right through the support plate 15. During this process, the limit block 37 corresponding to the upper end of the welding shell 14 moves upward until the left end of the welding shell 14 becomes the upper end. At this time, the welding shell 14 enters the area of ​​the auxiliary table 3. Due to the setting of the support plate 15, the box wall after welding will not fall down, but will still be on the welding shell 14. At this time, the power pump 2 29 can be controlled to work so that the inside of the suction cup 30 is negative pressure. The suction cup 30 first absorbs the box cover, and then controls the motor 22 to work. When the motor 22 works, it drives the screw to rotate. When the screw rotates, it drives the transmission block 26 to move forward. The forward sliding of the slider 25 and the slide rail 24 guides the forward movement of the transmission block 26. The transmission block 26 drives the mounting plate 27 to move forward. The mounting plate 27 drives a number of electric telescopic rods 6 23 and the mounting plate 3 to move. The mounting plate 3 drives the power pump 29 and the suction cup 30 to move until the suction cup 30 drives the box cover to move to the target position, and then controls the electric telescopic rod 6 23 to extend. The electric telescopic rod 6 23 drives the mounting plate 3 to move downward through the connecting block 28, so that the suction cup 30 drives the box cover to contact the upper end of the box wall, and then the contact end of the box cover and the box wall is touched. The welding is performed, and after the welding of the box cover is completed, the electric telescopic rod 6 23 is controlled to retract. The electric telescopic rod 6 23 drives the box cover and the box wall to separate from the welding shell 14 through the suction cup 30. At this time, the box wall can be polished and the internal parts of the oil tank can be welded. Then, the box bottom plate is placed on the upper end of the welding shell 14, and the power pump 1 inside the welding shell 14 is controlled to work. The box bottom plate is adsorbed on the upper end of the welding shell 14 through the negative pressure chamber and the negative pressure port 17. The power pump 1 and the power pump 29 can both adopt the fan of the existing technology, and then the electric telescopic rod 6 23 is controlled to extend so that the lower end of the box wall contacts the box bottom plate, and the lower end of the box wall and the contact end of the box bottom plate are welded to form a box body. The box bottom plate and the box cover are adsorbed and fixed in the welding process by negative pressure adsorption, avoiding This avoids shaking and deflection during the welding process of the box wall, box bottom plate and box cover plate, thereby improving the welding quality. Finally, the box body is placed in the idle position of the auxiliary table 3 through the operation of the motor 22 and the electric telescopic rod 6 23, and the reinforcing ribs and oil tank components are welded on the box body to form an oil tank. After the welding is completed, the suction cup 30 is controlled to be in sealing contact with the leak test port of the oil tank, and then the air supply direction of the power pump 2 is adjusted so that the power pump 2 can send gas to the inside of the oil tank through the suction cup 30 and the leak test port, so as to determine whether the oil tank has a leak. If the oil tank does not leak and the leak test is qualified, the air supply direction of the power pump 2 is continued to be adjusted, and the oil tank is adsorbed by the suction cup 30. Then, the motor 22 and the electric telescopic rod 6 23 are operated to place the oil tank on the finished product conveying mechanism, and the subsequent painting steps are carried out.Optionally, the transformer oil tank may be cleaned before painting, and the existing technology may be used to clean the transformer oil tank.
