Description

Technical Field

[0001] This invention relates to the field of meter box technology, and more specifically, to a welding fixture for a smart meter box and its method of use. Background Technology

[0002] A meter box is a housing used to install electrical equipment such as meters, switches, and fuses. It plays a crucial role in the power system. Meter boxes not only protect internal electrical components from external environmental influences such as dust, moisture, and impacts, but also ensure the safety of operators, preventing dangerous situations like electric shock. Smart meter boxes, as a type of meter box, integrate advanced information technology and intelligent management systems. They can monitor the meter's operating status and power usage in real time and transmit this data to relevant management platforms. This allows power departments to manage and dispatch power more efficiently, promptly detect and handle meter faults and abnormal power consumption. The smart meter box welding fixture involved in this invention is a key tool in the smart meter box production process. It can precisely fix the various components of the meter box, ensuring the accuracy and stability of welding, thereby improving the production quality and efficiency of smart meter boxes. Through reasonable design and optimization, this welding fixture can adapt to smart meter boxes of different specifications and models, meeting diverse production needs.

[0003] According to patent document CN121267507A, a positioning and welding device for the top cover of a metal electric meter box is disclosed, including a conveying mechanism and a welding processing mechanism. The welding processing mechanism includes a support plate and two processing grooves. The support plate is provided with a movable support component, an adjustment box, and multiple rotating rollers. The processing grooves are provided with a four-way positioning component, a support component, and a multi-directional adjustable welding component. This invention realizes rapid loading and unloading of the electric meter box through the conveying mechanism, and enables simultaneous positioning welding and loading / unloading operations on both sides of the adjustment box through the movement of the movable support component and rotating rollers. The positioning operation of the electric meter box is performed by the adjustment component and the four-way positioning component, improving the positional stability of the electric meter box during processing. The multi-directional adjustable welding component enables welding processing at different positions and angles, making the welding operation more flexible and convenient. During the welding process, the adjustment box and the processing groove cooperate to form a enclosure structure on the outside of the electric meter box.

[0004] After the manufacturing process is completed, smart meter boxes typically require welding to tightly connect multiple independent components. This crucial step is essential for ensuring the long-term stability of the overall structure and the reliable sealing of the casing. During welding, operators generally use specialized clamping devices to effectively fix and precisely position the smart meter box, ensuring accurate joint positions and uniform weld quality. Notably, a complete meter box casing often requires welding operations on multiple different directions and surfaces, which places high demands on the flexibility of the clamping equipment. However, currently widely used traditional meter box positioning platforms, after achieving clamping and limiting functions, often struggle to conveniently adjust the spatial angle and specific position of the meter box according to welding requirements. This forces operators to frequently disassemble, re-clamp, or manually move the workpiece when changing work surfaces or welding in different directions. The entire process is cumbersome, time-consuming, and labor-intensive, significantly increasing the labor intensity of workers and severely restricting the efficiency and smoothness of the overall welding operation. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, this invention provides an intelligent meter box welding fixture and its usage method. The technical problem to be solved by this invention is that the traditional meter box positioning platform, which is widely used at present, often makes it difficult to conveniently adjust the spatial angle and specific position of the meter box according to welding requirements after realizing the clamping and limiting functions.

[0012] As a further aspect of the present invention: The outer walls of both rotating blocks are fitted with rectangular sliding groove type sleeves; the rear sides of both rectangular sliding groove type sleeves are fixedly connected to columnar push-pull rods; the front sides of both rectangular sliding groove type sleeves are fixedly connected to hinge block connecting plates; the front middle of the hinge block connecting plate is fixedly connected to a hinge block; the top and bottom of the front side of the hinge block are rotatably connected to expanding and contracting rotating rods; the outer walls of both expanding and contracting rotating rods, away from the hinge blocks, are rotatably connected to the rear side of the inner middle of the two T-shaped expanding and contracting plates; the rear ends of both columnar push-pull rods extend to the rear side of the two columnar push-pull rod guide blocks; and the rear ends of both columnar push-pull rods are fixedly connected to Z-shaped push-pull rods. The two Z-shaped push-pull blocks are fixedly connected to the bottom of their front sides with columnar side push-pull rods. The front sides of the two columnar side push-pull rods extend through the inner walls of the two columnar rod guide side blocks to the front sides of the columnar rod guide side blocks. The front ends of the two columnar side push-pull rods are fixedly connected to soil-shaped plate push-pull blocks. Soil-shaped plates are fixedly connected to the inner sides of the two soil-shaped plate push-pull blocks. A welded base plate is fixedly connected to the bottom of the soil-shaped plate. A columnar connecting rod for a meter box placement plate is rotatably connected to the inner wall of the front side of the middle part of the welded base plate. A meter box placement plate is fixedly connected to the top of the columnar connecting rod for a meter box placement plate. A second gear is fixedly connected to the bottom of the columnar connecting rod for a meter box placement plate.

[0013] As a further aspect of the present invention: the welding frame includes a welding protective outer frame, and the left and right sides of the bottom of the welding protective outer frame are fixedly connected to side L-shaped frame push-pull plates. The inner sides of the two side L-shaped frame push-pull plates are slidably connected to the outer sides of the two side guide plates. The rear sides of the top of the two side L-shaped frame push-pull plates are fixedly connected to the left and right sides of the bottom of the horizontal push-pull plate. The front side of the welding protective outer frame is provided with a frame rectangular groove.

[0014] As a further embodiment of the present invention: a welding arm connecting plate is fixedly connected to the bottom of the front middle part of the welding protective frame, a welding arm connecting pole is fixedly connected to the middle of the front side of the welding arm connecting plate, and a laser welding arm is fixedly connected to the rear side of the welding arm connecting pole.

[0015] In addition, the present invention also relates to a welding fixture for a smart meter box and a method for using the same, comprising the following steps: Step 1: Place the smart meter box on top of the meter box placement plate; Step 2: Start the motor. Its output end drives the angle adjustment gear to rotate. Since the angle adjustment gear meshes with the second gear at the bottom of the columnar connecting rod of the meter box placement plate, it drives the columnar connecting rod of the meter box placement plate to rotate, thereby realizing the rotation of the meter box placement plate and completing the angle adjustment of the smart meter box to meet different welding requirements. Step 3: After the angle adjustment is completed, start the electric push rod. The electric push rod pushes the L-shaped push-pull plate to slide on the top of the control mechanism horizontal plate. The racks on the left and right sides of the top front of the L-shaped push-pull plate cooperate with the gears on the columnar transmission crossbar, causing the columnar transmission crossbar to rotate. Step 4: The second transmission discs at both ends of the columnar transmission crossbar drive the transmission discs to rotate via the track. When the transmission discs rotate, the cross connecting rod inside rotates as well. The rotating block on the inner side of the cross connecting rod slides in the rectangular sliding groove sleeve, pushing the rectangular sliding groove sleeve to move backward. Step 5: The rectangular sliding groove type sleeve block moves backward, causing the columnar push-pull rod to slide inside the columnar push-pull rod guide block. The Z-shaped push-pull block at the rear end of the columnar push-pull rod moves along with it. The columnar side push-pull rod at the bottom front side of the Z-shaped push-pull block slides inside the columnar rod guide side block, pushing the soil pattern plate push-pull block and the soil pattern plate to move. The welded bottom plate at the bottom of the soil pattern plate moves accordingly and gets close to the surface of the vertical guide plate. Step Six: The hinge block connecting plate and hinge block on the front side of the rectangular slide block move with it. The retractable rotating rod on the hinge block rotates, causing the T-shaped retractable plate to slide in the guide groove of the vertical guide plate. The T-shaped retractable plate causes the convex slider to slide along the guide rail, causing the columnar connecting rod and the elliptical slide frame to move. The rotating rod block in the elliptical slide frame causes the rotating rod to rotate, which in turn causes the transverse retractable plate to move inward. The transverse retractable plate causes the clamping plate retractable block to slide on the horizontal guide plate through the second rotating rod, causing the clamping plate vertical connecting plate and the clamping plate outer plate to move. The clamping plate outer plate causes the inner clamping plate to move closer to both sides of the meter box. The slider slides inside the clamping plate outer plate. The spring compression plays a buffering role. The inner clamping plate clamps the meter box, completing the positioning and fixing. Step 7: When the L-shaped push-pull plate moves backward, the horizontal push-pull plates on both sides of the L-shaped push-pull plate also move backward. The horizontal push-pull plates drive the side L-shaped frame push-pull plates to slide outside the side guide plate, causing the welding protective frame to move backward and cover the smart meter box inside. The operator controls the laser welding arm to start welding the smart meter box. The laser welding arm is firmly connected to the welding protective frame through the welding arm connecting pole and the welding arm connecting plate, and performs efficient and precise welding along the preset welding path. Step 8: After one side is welded, restart the motor to engage the angle adjustment gear with the second gear, adjust the angle of the meter box placement plate again, rotate the unwelded side to a position that is easy to weld, restart the electric push rod, repeat the previous clamping action, so that the inner clamping plate tightly clamps the meter box again, ensuring that the meter box remains stable during the new welding process. Throughout the welding process, the welding protective frame always moves with the position and angle adjustment of the meter box to ensure protection for the welding operation.

[0016] The beneficial effects of this invention are as follows: This invention, by incorporating a welding table, control mechanism, and welding frame, achieves efficient positioning, clamping, and flexible multi-angle adjustment during the welding process of smart meter boxes, effectively improving welding precision and efficiency. Through the coordination of a motor-driven angle adjustment gear and a second gear, the angle of the meter box can be easily and precisely adjusted to adapt to different welding needs, avoiding welding quality problems caused by inconvenient angle adjustment in traditional welding methods. An electric push rod drives a series of transmission components to achieve the clamping action of the clamping plate, and a spring buffer structure is incorporated to securely fix the meter box while effectively preventing damage. The welding protective frame can adjust with the electric... The meter box can be moved by adjusting its position and angle, providing reliable protection for welding operations and reducing the impact of spatter and fumes generated during welding on operators and the surrounding environment. Throughout the welding process, the meter box remains firmly fixed, and the laser welding arm can perform efficient and precise welding along the preset welding path, greatly improving welding quality and efficiency. In addition, the invention has a reasonable structural design, with tight cooperation between various components, convenient operation, and reduced labor intensity for operators. In practical applications, it can significantly improve the welding production efficiency of smart meter boxes and reduce production costs, showing good market application prospects and economic benefits.

After the angle adjustment is completed, the electric push rod 124 is activated. The electric push rod 124 pushes the L-shaped push-pull plate 213 to slide on the top of the horizontal plate 28 of the control mechanism. The racks 214 on the left and right sides of the front top of the L-shaped push-pull plate 213 engage with the gears 212 on the columnar transmission crossbar 210, causing the columnar transmission crossbar 210 to rotate. The second transmission discs at both ends of the columnar transmission crossbar 210... 211 drives the transmission disc 26 to rotate via the track 27. When the transmission disc 26 rotates, the cross connecting rod 23 inside it also rotates. The rotating block 24 on the inner side of the cross connecting rod 23 slides in the rectangular sliding groove sleeve 216, pushing the rectangular sliding groove sleeve 216 to move backward. The rearward movement of the rectangular sliding groove sleeve 216 drives the columnar push-pull rod 2110 to slide in the columnar push-pull rod guide block 215. The Z-shaped push-pull block 2111 at the rear end of the columnar push-pull rod 2110 also moves. The columnar side push-pull rod 2112 at the bottom front side of the Z-shaped push-pull block 2111 slides in the columnar rod guide side block 12112, pushing the soil-shaped plate push-pull block 2113 and the soil-shaped plate 2114 to move. The welded bottom plate 2115 at the bottom of the soil-shaped plate 2114 also moves and comes close to the surface of the vertical guide plate 121. At the same time, the hinge block connecting plate 217 and hinge block 218 on the front side of the rectangular slide block 216 also move. The retractable rotating rod 219 on the hinge block 218 rotates, causing the T-shaped retractable plate 128 to slide in the guide groove 126 of the vertical guide plate 121. The T-shaped retractable plate 128 causes the convex slider 127 to slide on the guide rail 122. The sliding of the convex slider 127 causes the columnar connecting rod 129 and the elliptical slide frame 1210 to move. The rotating rod abutment 1212 in the elliptical slide frame 1210 causes the rotating rod 1211 to rotate. The rotating rod 1211 causes the transverse retractable plate 1213 to move inward. The transverse retractable plate 1213 causes the second rotating rod 1211 to move inward. 14 rotates, causing the clamping plate expansion block 1215 to slide on the horizontal guide plate 123. The clamping plate expansion block 1215 drives the clamping plate vertical connecting plate 1216 and the clamping plate outer plate 1217 to move. The clamping plate outer plate 1217 drives the inner clamping plate 12111 to approach the left and right sides of the meter box. As the inner clamping plate 12111 approaches the meter box, the slider 1218 slides on the inner wall of the clamping plate outer plate 1217, and the spring 12110 is compressed, which plays a buffering role and avoids damage to the inner clamping plate 12111 and the meter box. When the inner clamping plate 12111 tightly clamps the meter box, the entire positioning and clamping action is completed. At this time, the meter box is firmly fixed on the meter box placement plate 2117. Next, the operator can adjust and prepare the welding equipment according to the specific welding requirements. Due to the coordinated action of the positioning fixture 12 and the control mechanism 2, the meter box is not only firmly fixed, but its angle has also been adjusted to a suitable position, making it convenient for the operator to perform welding operations from all directions. After one side is welded, the above operation is repeated. The motor 115 drives the angle adjustment gear 116 to mesh with the second gear 2118, and the angle of the meter box placement plate 2117 is adjusted again to rotate the unwelded side to a position that is easy to weld. Then, the electric push rod 124 is started again to repeat the previous clamping action, so that the inner clamping plate 12111 clamps the meter box tightly again, ensuring that the meter box remains stable during the new welding process. During the entire welding process, the triangular support base plate 112 and the side guide plate 113 of the support frame 11 ensure the stability of the welding table 1, so that the welding operation can be carried out on a stable platform. The side guide plate 113 also provides guidance for the installation and positioning of the welding table 1, ensuring the accuracy of its installation position.

[0022] like Figure 10As shown, the welding frame 3 includes a welding protective outer frame 31. The left and right sides of the bottom of the welding protective outer frame 31 are fixedly connected to side L-shaped frame push-pull plates 32. The inner sides of the two side L-shaped frame push-pull plates 32 are slidably connected to the outer sides of the two side guide plates 113. The rear sides of the top of the two side L-shaped frame push-pull plates 32 are fixedly connected to the left and right sides of the bottom of the horizontal push-pull plate 2119. The front side of the welding protective outer frame 31 is provided with a frame rectangular groove 33. The bottom of the middle part of the front side of the welding protective outer frame 31 is fixedly connected to a welding arm connecting plate 34. The middle part of the front side of the welding arm connecting plate 34 is fixedly connected to a welding arm connecting pole 35. The rear side of the welding arm connecting pole 35 is fixedly connected to a laser welding arm 36. In addition, when the L-shaped push-pull plate 213 moves to the rear, the horizontal push-pull plates 2119 on the left and right sides of the L-shaped push-pull plate 213 also move to the rear. The movement of the horizontal push-pull plates 2119 causes the side L-shaped frame push-pull plate 32 to slide on the outside of the side guide plate 113, thereby causing the welding protective frame 31 to move to the rear. After the welding protective frame 31 moves to the appropriate position, it covers the smart meter box inside, which to a certain extent blocks the sparks and spatter generated during the welding process and plays a protective role. At this time, the operator can control the laser welding arm 36 to start welding the smart meter box. The laser welding arm 36 is firmly connected to the welding protective frame 31 through the welding arm connecting pole 35 and the welding arm connecting plate 34, which can accurately perform welding operations on the meter box. During the welding process, since the smart meter box has been firmly fixed on the meter box placement plate 2117 and the angle has been adjusted to a suitable position, the laser welding arm 36 can perform efficient and precise welding along the preset welding path. After welding one area is completed, the operator can adjust and re-clamp the meter box again using motor 115 and electric push rod 124 to weld other areas of the meter box. Throughout the welding process, the welding protective frame 31 moves with the position and angle adjustment of the meter box to ensure protection for the welding operation under any circumstances.

[0023] In addition, the present invention also relates to a welding fixture for a smart meter box and a method for using the same, comprising the following steps: Step 1: Place the smart meter box on top of the meter box placement plate 2117; Step 2: Start the motor 115, and its output end drives the angle adjustment gear 116 to rotate. Since the angle adjustment gear 116 meshes with the second gear 2118 at the bottom of the columnar connecting rod 2116 of the meter box placement plate, it drives the columnar connecting rod 2116 of the meter box placement plate to rotate, thereby realizing the rotation of the meter box placement plate 2117 and completing the angle adjustment of the smart meter box to meet different welding requirements. Step 3: After the angle adjustment is completed, start the electric push rod 124. The electric push rod 124 pushes the L-shaped push-pull plate 213 to slide on the top of the control mechanism horizontal plate 28. The racks 214 on the left and right sides of the top front of the L-shaped push-pull plate 213 cooperate with the gears 212 on the columnar transmission horizontal bar 210 to make the columnar transmission horizontal bar 210 rotate. Step 4: The second transmission discs 211 at both ends of the columnar transmission crossbar 210 drive the transmission disc 26 to rotate via the track 27. When the transmission disc 26 rotates, the cross connecting rod 23 inside it rotates as well. The rotating abutment 24 on the inner side of the cross connecting rod 23 slides in the rectangular sliding groove sleeve 216, pushing the rectangular sliding groove sleeve 216 to move backward. Step 5: The rectangular sliding groove type sleeve block 216 moves backward, causing the columnar push-pull rod 2110 to slide within the columnar push-pull rod guide block 215. The Z-shaped push-pull block 2111 at the rear end of the columnar push-pull rod 2110 moves accordingly. The columnar side push-pull rod 2112 at the bottom front side of the Z-shaped push-pull block 2111 slides within the columnar rod guide side block 12112, pushing the soil pattern plate push-pull block 2113 and the soil pattern plate 2114 to move. The welded base plate 2115 at the bottom of the soil pattern plate 2114 moves accordingly and comes close to the surface of the vertical guide plate 121. Step Six: The hinge block connecting plate 217 and hinge block 218 on the front side of the rectangular slide block 216 move with it. The expanding and contracting rotating rod 219 on the hinge block 218 rotates, causing the T-shaped expanding plate 128 to slide in the guide groove 126 of the vertical guide plate 121. The T-shaped expanding plate 128 causes the convex slider 127 to slide along the guide rail 122, causing the columnar connecting rod 129 and the elliptical slide frame 1210 to move. The rotating rod abutment 1212 in the elliptical slide frame 1210 causes the rotating rod 1211 to rotate. The movement causes the transverse expansion plate 1213 to move inward. The transverse expansion plate 1213, through the second rotating rod 1214, causes the clamping plate expansion block 1215 to slide on the transverse guide plate 123, which in turn causes the clamping plate vertical connecting plate 1216 and the clamping plate outer plate 1217 to move. The clamping plate outer plate 1217 causes the inner clamping plate 12111 to move closer to both sides of the meter box. The slider 1218 slides inside the clamping plate outer plate 1217. The spring 12110 is compressed to provide a buffering effect. The inner clamping plate 12111 clamps the meter box, completing the positioning and fixing. Step 7: When the L-shaped push-pull plate 213 moves to the rear, the horizontal push-pull plates 2119 on the left and right sides of the L-shaped push-pull plate 213 also move to the rear. The horizontal push-pull plates 2119 drive the side L-shaped frame push-pull plates 32 to slide on the outside of the side guide plate 113, so that the welding protective frame 31 moves to the rear, covering the smart meter box inside. The operator controls the laser welding arm 36 to start welding the smart meter box. The laser welding arm 36 is firmly connected to the welding protective frame 31 through the welding arm connecting pole 35 and the welding arm connecting plate 34, and performs efficient and precise welding along the preset welding path. Step 8: After one side is welded, restart motor 115 to engage angle adjustment gear 116 with second gear 2118, adjust the angle of meter box placement plate 2117 again, rotate the unwelded side to a position that is easy to weld, restart electric push rod 124, repeat the previous clamping action, so that inner clamping plate 12111 clamps the meter box tightly again, ensuring that the meter box remains stable during the new welding process. Throughout the welding process, welding protective frame 31 always moves with the position and angle adjustment of the meter box to ensure protection for the welding operation.

[0024] Working principle of this invention: When welding a smart meter box is required, the smart meter box is first placed on top of the meter box mounting plate 2117. At this time, the motor 115 is started. After the motor 115 starts, its output end drives the angle adjustment gear 116 to rotate. The rotation of the angle adjustment gear 116 meshes with the second gear 2118 at the bottom of the columnar connecting rod 2116 of the meter box mounting plate, thereby driving the columnar connecting rod 2116 of the meter box mounting plate to rotate. The rotation of the columnar connecting rod 2116 of the meter box mounting plate causes the top meter box mounting plate 2117 to rotate as well, thereby realizing the adjustment of the angle of the smart meter box to meet different welding requirements. After the angle adjustment is completed, the electric push rod 124 is started. The electric push rod 124 pushes the L-shaped push-pull plate 213 to slide on the top of the control mechanism horizontal plate 28. The racks 214 on the left and right sides of the front of the top of the L-shaped push-pull plate 213 cooperate with the gears 212 on the columnar transmission horizontal rod 210. This causes the columnar transmission crossbar 210 to rotate. The second transmission discs 211 at both ends of the columnar transmission crossbar 210 drive the transmission disc 26 to rotate via the track 27. When the transmission disc 26 rotates, the cross connecting rod 23 inside it also rotates. The rotating abutment 24 on the inner side of the cross connecting rod 23 slides in the rectangular sliding groove sleeve 216, pushing the rectangular sliding groove sleeve 216 to move backward. The backward movement of the rectangular sliding groove sleeve 216 causes the columnar push-pull rod 2110 to slide in the columnar push-pull rod guide block 215. The Z-shaped push-pull block 2111 at the rear end of the columnar push-pull rod 2110 also moves. The columnar side push-pull rod 2112 at the bottom front side of the Z-shaped push-pull block 2111 slides in the columnar rod guide side block 12112. The movement of the soil-shaped plate push-pull block 2113 and soil-shaped plate 2114 causes the welded base plate 2115 at the bottom of the soil-shaped plate 2114 to move closer to the surface of the vertical guide plate 121. At the same time, the hinge block connecting plate 217 and hinge block 218 on the front side of the rectangular sliding groove type sleeve block 216 also move. The retractable rotating rod 219 on the hinge block 218 rotates, causing the T-shaped retractable plate 128 to slide in the guide groove 126 of the vertical guide plate 121. The T-shaped retractable plate 128 causes the convex slider 127 to slide on the guide rail 122. The sliding of the convex slider 127 causes the columnar connecting rod 129 and the elliptical sliding groove frame 1210 to move. The rotating rod in the elliptical sliding groove frame 1210 abuts against the block. 1212 drives the rotating rod 1211 to rotate, which in turn drives the transverse expanding plate 1213 to move inward. The transverse expanding plate 1213 drives the second rotating rod 1214 to rotate, which in turn causes the clamping plate expanding block 1215 to slide on the transverse guide plate 123. The clamping plate expanding block 1215 drives the clamping plate vertical connecting plate 1216 and the clamping plate outer plate 1217 to move. The clamping plate outer plate 1217 drives the inner clamping plate 12111 to move closer to the left and right sides of the meter box. As the inner clamping plate 12111 moves closer to the meter box, the slider 1218 slides on the inner wall of the clamping plate outer plate 1217, and the spring 12110 is compressed, which plays a buffering role and avoids damage to the inner clamping plate 12111 and the meter box.When the inner clamping plate 12111 tightly clamps the meter box, the entire positioning and clamping action is completed. At this time, the meter box is firmly fixed on the meter box placement plate 2117. In addition, when the L-shaped push-pull plate 213 moves backward, the horizontal push-pull plates 2119 on both sides of the L-shaped push-pull plate 213 also move backward. The movement of the horizontal push-pull plates 2119 causes the side L-shaped frame push-pull plates 32 to slide outside the side guide plate 113, thereby causing the welding protective frame 31 to move backward. After the welding protective frame 31 moves to the appropriate position, it covers the smart meter box inside. At this time, the operator can control the laser welding arm 36 to start welding the smart meter box. The laser welding arm 36 is firmly connected to the welding protective frame 31 through the welding arm connecting rod 35 and the welding arm connecting plate 34, which can accurately perform welding operations on the meter box. During the welding process, since the smart meter box is securely fixed on the meter box placement plate 2117 and its angle has been adjusted to a suitable position, the laser welding arm 36 can perform efficient and precise welding along the preset welding path. Once one side is welded, the above operation is repeated. The motor 115 drives the angle adjustment gear 116 to mesh with the second gear 2118, readjusting the angle of the meter box placement plate 2117 and rotating the unwelded side to a position suitable for welding. Then, the electric push rod 124 is activated again, repeating the previous clamping action, so that the inner clamping plate 12111 tightly clamps the meter box again, ensuring the meter box remains stable during the new welding process. Throughout the welding process, the welding protective frame 31 moves with the position and angle adjustment of the meter box, ensuring protection for the welding operation under any circumstances.

The racks (214) on the left and right sides of the front of the top of the L-shaped push-pull plate (213) cooperate with the gears (212) on the columnar transmission crossbar (210) to make the columnar transmission crossbar (210) rotate. Step 4: The second transmission discs (211) at both ends of the columnar transmission crossbar (210) drive the transmission disc (26) to rotate through the track (27). When the transmission disc (26) rotates, the cross connecting rod (23) inside it rotates as well. The rotating block (24) inside the cross connecting rod (23) slides in the rectangular sliding groove sleeve (216), pushing the rectangular sliding groove sleeve (216) to move backward. Step 5: The rectangular sliding groove type sleeve block (216) moves backward, causing the columnar push-pull rod (2110) to slide in the columnar push-pull rod guide block (215). The Z-shaped push-pull block (2111) at the rear end of the columnar push-pull rod (2110) moves along with it. The columnar side push-pull rod (2112) at the bottom front side of the Z-shaped push-pull block (2111) slides in the columnar rod guide side block (12112), pushing the soil-shaped plate push-pull block (2113) and the soil-shaped plate (2114) to move. The welded bottom plate (2115) at the bottom of the soil-shaped plate (2114) moves accordingly and gets close to the surface of the vertical guide plate (121). Step Six: The hinge block connecting plate (217) and hinge block (218) on the front side of the rectangular slide block (216) move with it. The retractable rotating rod (219) on the hinge block (218) rotates, causing the T-shaped retractable plate (128) to slide in the guide groove (126) of the vertical guide plate (121). The T-shaped retractable plate (128) causes the convex slider (127) to slide along the guide rail (122), causing the columnar connecting rod (129) and the elliptical slide frame (1210) to move. The rotating rod abutment (1212) in the elliptical slide frame (1210) drives the rotating rod (121) to move. 1) Rotation, which in turn drives the transverse expansion plate (1213) to move inward. The transverse expansion plate (1213) causes the clamping plate expansion block (1215) to slide on the transverse guide plate (123) through the second rotating rod (1214), which drives the clamping plate vertical connecting plate (1216) and the clamping plate outer plate (1217) to move. The clamping plate outer plate (1217) drives the inner clamping plate (12111) to approach the two sides of the meter box. The slider (1218) slides inside the clamping plate outer plate (1217). The spring (12110) is compressed to play a buffering role. The inner clamping plate (12111) clamps the meter box to complete the positioning and fixing. Step 7: When the L-shaped push-pull plate (213) moves to the rear, the horizontal push-pull plates (2119) on the left and right sides of the L-shaped push-pull plate (213) move to the rear. The horizontal push-pull plates (2119) drive the side L-shaped frame push-pull plates (32) to slide on the outside of the side guide plate (113), so that the welding protective frame (31) moves to the rear, covering the smart meter box inside. The operator controls the laser welding arm (36) to start welding the smart meter box. The laser welding arm (36) is firmly connected to the welding protective frame (31) through the welding arm connecting pole (35) and the welding arm connecting plate (34), and performs efficient and precise welding along the preset welding path. Step 8: After one side is welded, start the motor (115) again to drive the angle adjustment gear (116) to mesh with the second gear (2118), adjust the angle of the meter box placement plate (2117) again, rotate the unwelded side to a position that is easy to weld, start the electric push rod (124) again, repeat the previous clamping action, so that the inner clamping plate (12111) clamps the meter box tightly again, ensuring that the meter box remains stable during the new welding process. Throughout the welding process, the welding protective frame (31) always moves with the position and angle adjustment of the meter box to ensure protection for the welding operation.
