Description

Technical Field

[0001] This utility model relates to the field of stainless steel water tank processing technology, specifically a welding fixture for stainless steel water tank plates. Background Technology

[0002] Stainless steel water tanks are usually made of multiple standard-sized steel plates. During the production process, welding fixtures are used to clamp and fix the steel plates and assemble them into the shape of the tank. Then, the four corner joints are welded together.

[0003] CN214444156U discloses a welding fixture for processing stainless steel water tanks, including a worktable, a fixed frame, and a support base. The fixed frame is located on the upper end of the worktable and is symmetrically distributed. The support frame is fixedly connected to the outside of the fixed frame by welding. A bidirectional hollow clamping block is provided on the upper end of the worktable, allowing stainless steel water tanks of different sizes to be placed on the upper end of the worktable. The hollow clamping block can clamp and fix the placed water tank, and the height of the placed stainless steel water tank can be adjusted according to its size. A telescopic frame can be extended and retracted inside the support frame, and then a limiting block is inserted into the limiting hole to fix the adjusted position. The bidirectional hollow clamping block allows for convenient and clear welding of the clamped position during the welding process, making it highly applicable.

[0004] The aforementioned welding fixtures for stainless steel water tank processing only clamp the steel plate on one side or use a single-point fixing method, which makes the steel plate prone to displacement during welding, causing weld misalignment. In addition, the lack of an automated splicing mechanism makes it impossible to accurately move and splice the four steel plates into the shape of the tank, making it difficult to achieve the precise position requirements of the steel plates during the splicing process, thus affecting the overall processing quality of the water tank. Therefore, a new welding fixture for stainless steel water tank plates is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background, this utility model proposes a welding fixture for stainless steel water tank plates.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A stainless steel water tank plate welding fixture of this utility model includes a base, an installation groove inside the base, a first motor installed in the installation groove, a rotating disk installed at the output end of the first motor, a support plate fixedly connected to the rotating disk, a fixed clamping seat fixedly connected to the support plate, two first electric push rods installed on both side walls of the fixed clamping seat, each first electric push rod having a first clamping plate mounted at its actuating end, a first sliding groove opened on the support plate, a first slider slidably mounted in the first sliding groove, a first movable clamping seat fixedly connected to the top side of the first slider, two second electric push rods installed on both side walls of the first movable clamping seat, each second electric push rod having a second clamping plate mounted at its actuating end, a first lead screw rotatably mounted in the first sliding groove, and the first lead screw passing through the first slider, a first motor installed on the outer side wall of the support plate, the output end of the first motor connected to one end of the first lead screw, a first movable frame fixedly connected to the top side of the first slider, and a fixed frame installed on the support plate, the first movable frame and the fixed frame... Each of the four steel plates is equipped with a first pneumatic cylinder on its top side. The actuating ends of both first pneumatic cylinders are fitted with first pneumatic rods, and the bottom ends of both first pneumatic rods are fixed to first upper clamping seats. Two third electric push rods are installed on the side walls of each first upper clamping seat, and the actuating end of each third electric push rod is fitted with a third clamping plate. To clamp and fix the four steel plates, two symmetrical steel plates are first placed in the fixed clamping seat and the first movable clamping seat, respectively. Then, the control panel is used to control the multiple first electric push rods and second electric push rods to operate synchronously, thereby enabling the two first clamping... The plates are brought closer together, causing the two second clamping plates to come together, thereby clamping and fixing the bottom of the two symmetrical steel plates. Then, through the control panel, the two first pneumatic cylinders are controlled to work synchronously, causing the two first upper clamping seats to move down to contact the top side of the steel plates. Through the control panel, multiple third electric push rods are controlled to work synchronously, causing the two third clamping plates on both sides of the steel plates to come together, thereby clamping and fixing the top of the two steel plates. By clamping the bottom ends of the two steel plates, the two symmetrical steel plates can be effectively clamped and fixed.

[0007] Preferably, the support plate has a second sliding groove, in which a double-acting lead screw is rotatably mounted. Both ends of the two double-acting lead screws are fitted with second sliders. A second motor is mounted on the outer wall of the support plate, and the output end of the second motor is connected to one end of the double-acting lead screw. A second movable clamping seat is fixedly connected to the top side of each of the two second sliders. Two fourth electric push rods are mounted on the side walls of each second movable clamping seat. A fourth clamping plate is fitted to the actuating end of each fourth electric push rod. A second movable frame is mounted on each of the two second sliders. A second pneumatic cylinder is mounted on the top side of each of the two movable frames. A second pneumatic rod is fitted to the actuating end of each of the two second pneumatic cylinders. A second upper clamping seat is fixedly connected to the bottom end of each second pneumatic rod. Two fifth electric push rods are mounted on the side walls of each second upper clamping seat. Each of the moving push rods is equipped with a fifth clamping plate. When clamping and fixing two other symmetrical steel plates, the other two steel plates are first placed in the second movable clamping seats. By operating the control panel, multiple fourth electric push rods are controlled to operate synchronously, so that the fourth clamping plates on both sides of the steel plates move closer to each other, thereby clamping and fixing the bottom ends of the two symmetrical steel plates. Then, by operating the control panel, two second pneumatic cylinders are controlled to operate synchronously, so that the second upper clamping seat moves down to contact the top side of the steel plate. Then, by operating the control panel, multiple fifth electric push rods are controlled to operate synchronously, so that the two fifth clamping plates on both sides of the steel plates move closer to each other, thereby clamping and fixing the top ends of the two steel plates. By clamping the bottom ends of the two steel plates, the other two symmetrical steel plates can be effectively clamped and fixed. After the four steel plates are clamped and fixed, during the assembly process, the second motor is started, causing the two second sliders to move the two symmetrical steel plates closer together until they contact each other, thus completing the assembly of three steel plates. When assembling the last steel plate, the first motor is started, causing the first slider to move the last steel plate until it reaches the appropriate position, i.e., after being assembled with the other three steel plates into a box shape. The second motor then stops operating. By using double clamping at the top and bottom for each steel plate, the four steel plates can be effectively clamped and fixed, preventing displacement of the steel plates during subsequent welding, improving welding accuracy and quality. At the same time, the four clamped and fixed steel plates can be accurately moved and assembled into a box shape. Through effective clamping and precise assembly control, a good foundation is provided for subsequent welding and connection, facilitating the subsequent welding and connection of the four steel plates assembled into a box shape, which helps to improve the processing quality of the water tank.

[0008] Preferably, a battery is installed on the outer wall of the support plate, and the battery supplies power to the first motor, the second motor, the first pneumatic cylinder, the second pneumatic cylinder and multiple electric push rods. When using the device, by setting up the battery, multiple drive devices can be powered without the need for external power cords, thus eliminating the constraints of cables and preventing the risk of cable entanglement.

[0009] Preferably, a vertical plate is fixed to the base, and a rectangular groove is formed on the vertical plate. A lifting block is slidably mounted in the rectangular groove. A third pneumatic cylinder is mounted on the lifting block, and a third pneumatic rod is mounted on the working end of the third pneumatic cylinder. A welding torch is mounted on the end of the third pneumatic rod. A recognition camera is mounted on the lifting block. A second lead screw is rotatably mounted in the rectangular groove, and the second lead screw passes through the lifting block. A second motor is mounted on the top side of the vertical plate, and the output end of the second motor is connected to one end of the second lead screw. After the four steel plates are spliced ​​into a box shape, when welding and fixing them, the first motor is started, causing the rotating disk to drive the support plate and the spliced ​​box to rotate. When one spliced ​​side corner of the box rotates to the welding mechanism position, the first motor... The operation is stopped, and then the third pneumatic cylinder is activated to move the welding rod on the welding gun to contact the splicing corner. Through the welding gun operation, the splicing joint can be welded and fixed. When the next splicing corner is welded and fixed, the first motor is activated again, causing the rotary table to rotate the box, which facilitates the welding and fixing of the remaining splicing corners of the box. By rotating the box with the rotary table, each splicing corner of the box can be rotated to the welding mechanism position in sequence. This design breaks the problem of limited welding angle caused by the fixed position of the box in the traditional welding method. It allows the welding gun to easily weld the splicing corners of different positions of the box without the need for operators to frequently move the welding equipment or adjust their own position, which greatly improves the convenience of welding operation.

[0010] Preferably, a control panel is installed on the base, and the control panel is used to control the start and stop of the first electric motor, the second electric motor, the first pneumatic cylinder, the second pneumatic cylinder, multiple electric push rods, the third pneumatic cylinder and the second electric motor. When using this device, by setting up the control panel, the start and stop of multiple drive devices can be centrally controlled together, which greatly improves the convenience of operation.

[0011] The advantages of this utility model are: 1. This utility model effectively clamps and fixes four steel plates by using double clamping at the top and bottom of each plate, preventing displacement of the steel plates during subsequent welding and improving welding accuracy and quality. At the same time, it can also accurately move and splice the four clamped and fixed steel plates into a box shape. Through effective clamping and precise splicing control, a good foundation is provided for subsequent welding and connection, which facilitates the subsequent welding and connection of the four steel plates spliced ​​into a box shape and helps to improve the processing quality of the water tank. 2. When welding and fixing the assembled box shape, this utility model uses a rotating disk to rotate the assembled box, which can sequentially rotate each spliced ​​side corner of the box to the welding mechanism position. This design breaks the problem of limited welding angle caused by the fixed position of the box in traditional welding methods, allowing the welding gun to easily weld the spliced ​​side corners of different positions of the box without the need for operators to frequently move the welding equipment or adjust their own position, greatly improving the convenience of welding operations.

The clamping seat 20 has two third electric push rods 21 installed on both sides of each first upper clamping seat 20. The working end of each third electric push rod 21 is equipped with a third clamping plate 22. During operation, in the stainless steel water tank processing, four steel plates need to be clamped and fixed. Then, the clamped and fixed steel plates are moved to splice them into the shape of the tank. After that, the four corner splices are welded together. First, two symmetrical steel plates are placed in the fixed clamping seat 6 and the first movable clamping seat 13 respectively. Then, the control panel 45 is used to control multiple first electric push rods 7 and second electric push rods 14 to work synchronously, thereby making the two first clamping plates 8 move closer to each other, and making the two third... The two clamping plates 15 come together to clamp and fix the bottom of the two symmetrical steel plates. Then, the control panel 45 controls the two first pneumatic cylinders 18 to work synchronously, causing the two first upper clamping seats 20 to move down until they contact the top side of the steel plate. The first pneumatic cylinders 18 then stop working. Next, the control panel 45 controls the multiple third electric push rods 21 to work synchronously, causing the two third clamping plates 22 on both sides of the steel plate to come together to clamp and fix the top of the two steel plates. By clamping the bottom of the two steel plates, the two symmetrical steel plates can be effectively clamped and fixed. A second slide groove 23 is provided on the support plate 5. A double-acting lead screw 25 is rotatably installed in the second slide groove 23. A second slider 24 is sleeved at both ends of the two double-acting lead screws 25. A second motor 26 is installed on the outer wall of the support plate 5. The output end of the second motor 26 is connected to one end of the double-acting lead screw 25.

Each of the two second pneumatic cylinders 31 is equipped with a second pneumatic rod 32 at its working end. Each of the two second pneumatic rods 32 is fixedly connected to a second upper clamping seat 33 at its bottom end. Each of the two second upper clamping seats 33 has two fifth electric push rods 34 mounted on its two side walls. Each fifth electric push rod 34 is equipped with a fourth clamping plate 29 at its working end. Five clamping plates 35; During operation, when clamping and fixing two other symmetrical steel plates, the other two steel plates are first placed in the second movable clamping seats 27 respectively. The control panel 45 is used to control multiple fourth electric push rods 28 to work synchronously, so that the fourth clamping plates 29 on both sides of the steel plates move closer to each other, thereby clamping and fixing the bottom ends of the two symmetrical steel plates. Then, the control panel 45 is used to control two second pneumatic cylinders 31 to work synchronously, so that the two second pneumatic rods 32 drive the two second upper clamping seats 33 to move down until the two second upper clamping seats 33 move down to contact the top side of the steel plates. The second pneumatic cylinders 31 stop working. Then, the control panel 45 is used to control multiple fifth electric push rods 34 to work synchronously, so that the two fifth clamping plates 35 on both sides of the steel plates move closer to each other, thereby clamping and fixing the top ends of the two steel plates. By clamping the bottom ends of the two steel plates, the other two symmetrical steel plates can be effectively clamped and fixed. After the four steel plates are clamped and fixed, during the splicing and assembly process, the second motor 26 is started, causing the bidirectional lead screw 25 to rotate. This forces the two second sliders 24 to move the two symmetrical steel plates closer together until the two symmetrical steel plates move to contact the other steel plate. At this point, the second motor 26 stops operating, thus completing the assembly and splicing of the three steel plates. When assembling the last steel plate, the first motor 12 is started, causing the first lead screw 11 to rotate. This forces the first slider 10 to move the last steel plate until it moves to the appropriate position, thus assembling it with the other three steel plates. After the steel plates are assembled into a box shape, the second motor 26 stops operating. By using double clamping at the top and bottom for each steel plate, the four steel plates can be effectively clamped and fixed, preventing the steel plates from shifting during subsequent welding. This improves the precision and quality of welding. At the same time, the four clamped and fixed steel plates can be accurately moved and assembled into a box shape. Through effective clamping and precise splicing control, a good foundation is provided for subsequent welding and connection, making it easier to weld and connect the four steel plates assembled into a box shape. This helps to improve the processing quality of the water tank. A battery 44 is installed on the outer wall of the support plate 5, and the battery 44 supplies power to the first motor 12, the second motor 26, the first pneumatic cylinder 18, the second pneumatic cylinder 31 and multiple electric push rods. When using the device, by setting the battery 44, multiple drive devices can be powered without the need for external power cords, thus eliminating the constraints of cables and preventing the risk of cable entanglement. Please see Figure 1-2As shown, a vertical plate 36 is fixed to the base 1. A rectangular groove 37 is provided on the vertical plate 36. A lifting block 38 is slidably mounted in the rectangular groove 37. A third pneumatic cylinder 39 is installed on the lifting block 38. A third pneumatic rod is installed at the working end of the third pneumatic cylinder 39. A welding torch 40 is installed at the end of the third pneumatic rod. A recognition camera 41 is installed on the lifting block 38. A second lead screw 42 is rotatably installed in the rectangular groove 37 and passes through the lifting block 38. A second motor 43 is installed on the top side of the vertical plate 36. The output end of the second motor 43 is connected to one end of the second lead screw 42. During operation, after the four steel plates are spliced ​​into a box shape, when welding and fixing them, the first motor 3 is started, causing the rotating disk 4 to drive the support plate 5 and the assembled box to rotate. When one spliced ​​side corner of the box rotates to the welding mechanism position, the first motor 3 stops working. Then, the third pneumatic cylinder 39 is started, causing the welding rod on the welding torch 40 to move... The welding torch 40 is moved to contact the splicing corner, and then welded and fixed at the splicing point. When welding and fixing the next splicing corner, the first motor 3 is started again, causing the rotating disk 4 to rotate the box, which facilitates the welding and fixing of the remaining splicing corners of the box. By rotating the assembled box through the rotating disk 4, each splicing corner of the box can be rotated to the welding mechanism position in sequence. This design breaks the problem of limited welding angle caused by the fixed position of the box in the traditional welding method, so that the welding torch 40 can easily weld the splicing corners of different positions of the box without the need for operators to frequently move the welding equipment or adjust their own position, which greatly improves the convenience of welding operation. By setting up a recognition camera 41, model WJ-500, real-time image acquisition and processing are used to accurately position the welding process, so that the welding torch 40 is accurately aligned with the weld seam, improving the welding accuracy. A control panel 45 is installed on the base 1, and the control panel 45 is used to control the start and stop of the first electric motor 3, the first motor 12, the second motor 26, the first pneumatic cylinder 18, the second pneumatic cylinder 31, multiple electric push rods, the third pneumatic cylinder 39, and the second electric motor 43. When the device is in operation, by setting up the control panel 45, the start and stop of multiple drive devices can be centrally controlled together, which greatly improves the convenience of operation. Working Principle: Existing stainless steel water tank processing and welding fixtures only clamp one side of the steel plate or use a single-point fixing method, which makes the steel plate prone to displacement during welding, causing weld misalignment. Furthermore, the lack of an automated splicing mechanism prevents the precise movement and splicing of the four steel plates into the tank shape, making it difficult to achieve accurate positioning during splicing and affecting the overall processing quality of the water tank. Therefore, this paper proposes a stainless steel water tank steel plate welding fixture to address these issues. During the stainless steel water tank processing, four steel plates need to be clamped and fixed. Then, the clamped and fixed steel plates are moved to splice into the tank shape. Afterward, the four corner joints are welded together. First, two symmetrical steel plates are placed in the fixed clamping seat 6 and the first movable clamping seat 13 respectively. Then, the operation is performed through the control panel 45. The system controls multiple first electric push rods 7 and second electric push rods 14 to operate synchronously, thereby bringing the two first clamping plates 8 and the two second clamping plates 15 closer together, thus clamping and fixing the bottom of the two symmetrical steel plates. Then, the control panel 45 controls two first pneumatic cylinders 18 to operate synchronously, causing the two first upper clamping seats 20 to move down until they contact the top side of the steel plate. The first pneumatic cylinders 18 then stop operating. Next, the control panel 45 controls multiple third electric push rods 21 to operate synchronously, bringing the two third clamping plates 22 on both sides of the steel plate closer together, thus clamping and fixing the top of the two steel plates. By clamping the bottom and bottom of the two steel plates, the two symmetrical steel plates can be effectively clamped and fixed. When clamping and fixing two other symmetrical steel plates, the two steel plates are first placed in the second movable clamping seats 27 respectively. The control panel 45 is used to control multiple fourth electric push rods 28 to work synchronously, so that the fourth clamping plates 29 on both sides of the steel plates move closer together, thereby clamping and fixing the bottom ends of the two symmetrical steel plates. Then, the control panel 45 is used to control two second pneumatic cylinders 31 to work synchronously, so that the two second pneumatic rods 32 drive the two second upper clamping seats 33 to move down until the two second upper clamping seats 33 move down to contact the top side of the steel plates. The second pneumatic cylinders 31 stop working. Then, the control panel 45 is used to control multiple fifth electric push rods 34 to work synchronously, so that the two fifth clamping plates 35 on both sides of the steel plates move closer together, thereby clamping and fixing the top ends of the two steel plates. By clamping the bottom ends of the two steel plates, the two other symmetrical steel plates can be effectively clamped and fixed. After the four steel plates are clamped and fixed, during the splicing and assembly process, the second motor 26 is started, causing the bidirectional lead screw 25 to rotate. This forces the two second sliders 24 to move the two symmetrical steel plates closer together until the two symmetrical steel plates move to contact the other steel plate. At this point, the second motor 26 stops operating, thus completing the assembly and splicing of the three steel plates. When assembling the last steel plate, the first motor 12 is started, causing the first lead screw 11 to rotate. This forces the first slider 10 to move the last steel plate until it moves to the appropriate position, thus assembling it with the other three steel plates. After the steel plates are assembled into a box shape, the second motor 26 stops operating. By using double clamping at the top and bottom for each steel plate, the four steel plates can be effectively clamped and fixed, preventing the steel plates from shifting during subsequent welding. This improves the precision and quality of welding. At the same time, the four clamped and fixed steel plates can be accurately moved and assembled into a box shape. Through effective clamping and precise splicing control, a good foundation is provided for subsequent welding and connection, making it easier to weld and connect the four steel plates assembled into a box shape. This helps to improve the processing quality of the water tank. After four steel plates are spliced ​​into a box shape, during welding and fixing, the first motor 3 is started, causing the rotating disk 4 to rotate the support plate 5 and the assembled box. When one of the spliced ​​corners of the box rotates to the welding mechanism position, the first motor 3 stops working. Then, the third pneumatic cylinder 39 is started, causing the welding rod on the welding gun 40 to move to contact the spliced ​​corner. Through the operation of the welding gun 40, the spliced ​​joint can be welded and fixed. When welding and fixing the next spliced ​​corner, the first motor 3 is started again, causing the rotating disk 4 to rotate the box, which facilitates the welding and fixing of the remaining spliced ​​corners of the box. By rotating the assembled box through the rotating disk 4, each spliced ​​corner of the box can be rotated to the welding mechanism position in sequence. This design breaks the problem of limited welding angle caused by the fixed position of the box in the traditional welding method, allowing the welding gun 40 to easily weld the spliced ​​corners of the box at different positions without the need for operators to frequently move the welding equipment or adjust their own position, greatly improving the convenience of welding operation.
