Description

Technical Field

[0001] This invention relates to the field of welding technology, and in particular to a welding apparatus for processing metering boxes. Background Technology

[0002] A metering box is a special device used for measuring electricity in a power system. Its core function is to safely and accurately measure the electricity consumed by users. It typically includes components such as an electricity meter, a transformer, a box body, and internal connecting lines. The box body requires welding during the production process. The bent metal plates are welded together at the joints using a welding device.

[0003] Commonly used welding equipment mainly includes two types: automatic corner welding machines and straight seam welding machines. Automatic corner welding machines are mainly used for welding right-angle joints of metal plates, while straight seam welding machines are mainly used for welding horizontal joints of metal plates. Since a single type of welding machine cannot simultaneously weld curved and straight welds, the production of the same batch of metering boxes may use both types of welding machines. This results in high production costs and complex production processes for metering boxes. In order to meet the process requirements of metering box welding production, this invention provides a welding device for metering box processing. Summary of the Invention

[0004] The technical problem this invention aims to solve is to provide a welding device for processing metering boxes. By setting an adjustment mechanism and a positioning bracket, the adjustment mechanism can adjust the angle of the positioning bracket, thereby allowing the positioning bracket to support and position straight and right-angle welds on the metering box body. The support mechanism can work with the positioning bracket to provide different types of support and limitation for the box body, thus ensuring the integrity and stability of the weld joint, preventing the spacing between welds from shifting due to the weight of the box body, improving the consistency and integrity of the welds during the welding process, and increasing welding accuracy.

Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0043] The welding apparatus for processing a metering box provided by the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0044] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0045] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0046] It is understood that the meanings of “on”, “above”, and “above” in this invention should be interpreted in the broadest manner, such that “on” means not only “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” means not only “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0047] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially related descriptive terms used herein can be interpreted similarly.

[0048] like Figures 1 to 3 As shown, an embodiment of the present invention provides a welding device for processing a metering box, including a base 1, a middle box 2 fixedly connected to the top of the base 1, a top box 3 fixedly connected to the top of the middle box 2, a drive mechanism 4 fixedly connected to the top of the top box 3, a welding head 5 mounted on the drive mechanism 4, a piano key pressure plate 6 fixedly connected to the bottom of the top box 3, and a positioning bracket 7 rotatably connected to the middle box 2.

[0049] In the above structure, the base 1, the middle box 2, and the top box 3 form the support structure system of this device. The top box 3 is used to install and fix the drive mechanism 4, and the middle box 2 is used to install the positioning bracket 7. The drive mechanism 4 can drive the welding head 5 to move linearly on the top of the top box 3. When the operator places the box to be welded on the top of the positioning bracket 7, the welding head 5 can perform welding on the box under the drive of the drive mechanism 4. In this technical solution, the working principle of the drive mechanism 4 driving the welding head 5 to move linearly on the top of the top box 3, and the working principle of the welding head 5 welding the box of the metering box on the top of the positioning bracket 7 are both disclosed as prior art and will not be described in detail here.

[0050] As one implementation method in this embodiment, such as Figures 1 to 11 As shown, the adjustment mechanism is used to adjust the relative position between the positioning bracket 7 and the middle box 2. The adjustment mechanism is connected to the positioning bracket 7 and includes an adjustment rod 10 fixedly connected to one end of the positioning bracket 7. The end of the adjustment rod 10 is provided with a slot 11. Two adjustment discs 12 are fixedly connected to the outer wall of the slot 11. The adjustment discs 12 are provided with screw holes 14. A screw cylinder 15 is fixedly connected to the outer wall of the middle box 2. The positioning bracket 7 has a right-angled triangular outline. A copper strip 8 is fixedly connected inside the positioning bracket 7. Two limiting plates 9 are fixedly connected to the top of the positioning bracket 7. The two limiting plates 9 are symmetrically installed on both sides of the top of the copper strip 8. A plug rod 13 that matches the outline of the slot 11 is fixedly connected to the inner wall of the adjustment disc 12. The two adjustment discs 12 are fixed together by screws. A bolt is inserted into the screw hole 14 and the bolt passes through the screw hole 14 and is screwed and fixed inside the screw cylinder 15.

[0051] In the above structure, the positioning bracket 7 has a right-angled triangular outline, with the top of the positioning bracket 7 being the hypotenuse of the right-angled triangle and the bottom of the positioning bracket 7 being the two right-angled sides of the right-angled triangle. The copper strip 8 is fixedly connected to the positioning bracket 7 by screws. The top and bottom of the positioning bracket 7 have grooves corresponding to the positions of the copper strip 8. This arrangement allows the welding head 5 to directly contact the copper strip 8 during the welding process of the metering box, avoiding contact with the positioning bracket 7 and preventing damage to the positioning bracket 7. It is worth mentioning that the size of the top of the copper strip 8 is larger than the size of its bottom, so that the copper strip 8 can be inserted into the positioning bracket 7 from top to bottom. Since the positioning bracket 7 has grooves that match the outline of the copper strip 8, the positioning bracket 7 can wrap and limit the copper strip 8. Finally, the top of the copper strip 8 is blocked and fixed by the limiting plate 9, thereby achieving the effect of fixing the copper strip 8. This arrangement can improve the efficiency of the staff in replacing the copper strip 8.

[0052] Furthermore, since the overall outline of the positioning bracket 7 is a right-angled triangle, the shape of the contact surface between the positioning bracket 7 and the metering box can be adjusted by rotating the positioning bracket 7 180 degrees. This allows the positioning bracket 7 to simultaneously support and position the metering box with both horizontal and right-angle welds, thus increasing the range of applications of the positioning bracket 7. In addition, since grooves corresponding to the positions of the copper strips 8 are opened at the top and bottom of the positioning bracket 7, the welding head 5 will directly contact the copper strips 8 during the welding process, whether the positioning bracket 7 is supporting and positioning the metering box with horizontal or right-angle welds, ensuring the safety of the positioning bracket 7 during use.

[0053] Furthermore, the end of the adjusting rod 10 extends through the middle housing 2 to the outside of the middle housing 2. Two adjusting discs 12 are installed on the outer wall of the slot 11 and can be engaged with the threaded sleeves 15 on the outer wall of the middle housing 2. Specifically, both adjusting discs 12 are inserted into the slot 11 via insert rods 13. After the two adjusting discs 12 are inserted, they are fixed together with screws. This installation structure ensures the firmness and stability of the engagement between the adjusting discs 12 and the adjusting rod 10. The threaded holes 14 correspond to the positions of the threaded sleeves 15, and the included angle between the threaded holes 14 on the two adjusting discs 12 is 180 degrees. When the operator uses screws to adjust the adjusting discs 12... After being fixed to the screw-in sleeve 15, the positioning bracket 7 cannot rotate on the central housing 2. When the operator needs to adjust the angle of the positioning bracket 7, first remove the screws from the adjusting turntable 12 and the screw-in sleeve 15, then rotate the two adjusting turntables 12 180 degrees. After rotation, fix the adjusting turntables 12 back to the screw-in sleeve 15 with the screws to achieve the fixed effect of the positioning bracket 7. The above structure not only allows the positioning bracket 7 to rotate and adjust its angle on the central housing 2, but also allows the operator to refer to the actual rotation angle of the positioning bracket 7 with the screw hole 14 during the angle adjustment process, ensuring the accuracy of the angle adjustment of the positioning bracket 7 and the convenience of the adjustment process.

[0054] As one implementation method in this embodiment, such as Figures 12 to 21As shown, the support mechanism is used to support and limit the body of the metering box to be welded. The support mechanism is connected to the base 1 and includes two bottom horizontal frames 16 fixedly connected to the inner wall of the base 1. The two bottom horizontal frames 16 are fixedly connected together by two bottom vertical frames 17. The two bottom horizontal frames 16 and the two bottom vertical frames 17 form a rectangular outline. Top horizontal frames 18 and top vertical frames 19 are respectively installed on the top of the bottom horizontal frames 16 and the bottom vertical frames 17. The bottom vertical frames 17 and the top vertical frames 19 are connected together by scissor arms 20. The two ends of the scissor arms 20 are rotatably connected to the bottom vertical frames 17 and the top vertical frames 19 respectively. A rotating shaft 21 is rotatably connected at the center of the scissor arm 20. A drive screw 22 is rotatably connected to the top horizontal frame 18. A drive seat 23 is screwed onto the outer wall of the drive screw 22. A handwheel 24 is fixedly connected to the end of the drive screw 22 away from the drive seat 23. A constraint frame 25 is fixedly connected to the outer wall of both the bottom vertical frame 17 and the top vertical frame 19. A slide rod 26 is fixedly connected to both ends of the drive seat 23. The slide rod 26 is slidably connected to the constraint frame 25 on the outer wall of the top vertical frame 19. The slide rods 26 at both ends of the drive seat 23 first pass through the scissor arm 20 and then extend into the constraint frame 25, so that the slide rod 26 and the scissor arm 20 cooperate with each other by means of the limiting effect of the constraint frame 25.

[0055] In the above structure, the bottom horizontal frame 16, the bottom vertical frame 17, the top horizontal frame 18, the top vertical frame 19, and the scissor arm 20 form the support structure system of the support mechanism. The bottom of this structure system is formed by the bottom horizontal frame 16 and the bottom vertical frame 17 forming a rectangular outline, and the top is formed by the top horizontal frame 18 and the top vertical frame 19 forming a rectangular outline. The frame structures of the two upper rectangular outlines are connected together by the scissor arm 20. Since the pivot 21 is rotatably connected at the middle position of the scissor arm 20, the support structure system can perform lifting and lowering movements.

[0056] Furthermore, the bottom horizontal frame 16 and the bottom vertical frame 17 are fixed to the base 1 with screws. When the operator turns the handwheel 24, the drive screw 22 rotates on the top horizontal frame 18. During the rotation of the drive screw 22, the slide rods 26 at both ends of the drive seat 23 slide in the groove on the constraint frame 25 under the driving action of the thread. During the sliding process, the top horizontal frame 18 and the top vertical frame 19 are pulled to move up and down. During the movement of the top horizontal frame 18 and the top vertical frame 19, the scissor arm 20 supports and limits the top horizontal frame 18 and the top vertical frame 19. Thus, the height difference between the top horizontal frame 18 and the top vertical frame 19 and the bottom horizontal frame 16 and the bottom vertical frame 17 is adjusted by the driving action of the drive screw 22.

[0057] The aforementioned adjustment structure is a mature existing technology in the field of mechanical technology. Therefore, the detailed working principle of adjusting the height difference between the top horizontal frame 18 and the top vertical frame 19 and the bottom horizontal frame 16 and the bottom vertical frame 17 is disclosed as prior art in this application and will not be elaborated here.

[0058] In this embodiment, as Figures 12 to 21 As shown, a first adjusting plate 27 is fixedly connected to the outer walls of both ends of the top vertical frame 19. A second adjusting plate 28 is rotatably connected to the outer wall of the first adjusting plate 27. A first support rod 29 is rotatably connected to the outer wall of the second adjusting plate 28. A first adjusting groove 30 with an arc-shaped profile is opened on the first adjusting plate 27. A first screw is fixedly connected to one end of the second adjusting plate 28 near the first adjusting plate 27. The first screw is inserted into the first adjusting groove 30, and a bolt is screwed to the end of the first screw. A second adjusting groove 31 is opened on the second adjusting plate 28. A second screw is fixedly connected to both ends of the first support rod 29. The second screw is inserted into the second adjusting groove 31, and a bolt is screwed to the end of the second screw. Two second support rods 32 are slidably connected to the top horizontal frame 18. A third screw is fixedly connected to both ends of the second support rod 32. A third adjusting groove 33 is opened on the top horizontal frame 18. A third screw is slidably connected to the third adjusting groove 33, and a bolt is screwed to the end of the third screw.

[0059] In the above structure, the first screw on the second adjusting plate 28 can slide within the first adjusting groove 30 on the first adjusting plate 27, and the nut is used to fix the relative position between the second adjusting plate 28 and the first adjusting plate 27; the second screws at both ends of the first support rod 29 can slide within the second adjusting groove 31 on the second adjusting plate 28, and the nut is used to fix the relative position between the first support rod 29 and the second adjusting plate 28; therefore, through the above structure, the adjustment effect of the second adjusting plate 28 and the first adjusting plate 27 on the first support rod 29 not only allows the first support rod 29 to rotate and adjust its angle on the outside of the top vertical frame 19, but also allows the relative distance between the first support rod 29 and the top vertical frame 19 to be slidably adjusted. Furthermore, the third screws at both ends of the second support rod 32 can slide within the third adjusting groove 33 on the top horizontal frame 18, and the nut is used to fix the relative position between the second support rod 32 and the top horizontal frame 18.

[0060] As mentioned above, the operator can adjust the angle of the positioning bracket 7 by rotating it to achieve the supporting and positioning effect of the measuring box with different shapes. Combined with the adjustment effect of the first support rod 29 and the second support rod 32 in the support mechanism, this device has two different operating states: State 1 (e.g.) Figure 19As shown), the hypotenuse of the right-angled triangle outline of the positioning bracket 7 is located at the top. The metering box to be welded is then placed on top of the positioning bracket 7. The positioning bracket 7 can support and position the horizontal plate of the box. Then, the height and angle of the two first support rods 29 are adjusted so that the first support rods 29 can be precisely clamped and fixed to both sides of the metering box. The positioning effect of the first support rods 29 on both sides of the box ensures the integrity and stability of the weld joint, preventing the spacing between welds from shifting due to the weight of the box itself. This improves the consistency and integrity of the weld during the welding process and increases welding accuracy. State Two (as shown) Figure 20 and 21 As shown in the diagram, the two right-angled sides of the positioning bracket 7 are located at the top. The metering box to be welded is then placed on top of the positioning bracket 7. The positioning bracket 7 supports and positions the two right-angled sides of the box. Then, the operator adjusts the distance between the two second support rods 32 so that the second support rods 32 can precisely support the other two right-angled sides of the box corresponding to the position of the positioning bracket 7. Finally, the height and angle of the first support rod 29 are adjusted so that the first support rod 29 supports the two plates adjacent to the position of the positioning bracket 7 on the box. With the coordinated action of the first support rod 29 and the second support rod 32, the box can be stably supported, thus ensuring the integrity and stability of the weld joint during welding. This further prevents the spacing between weld joints from shifting due to the weight of the box itself, further improving the consistency and integrity of the weld during welding and ensuring the accuracy of the welding.

[0061] The working principle of the technical solution provided by this invention is as follows:

[0062] When welding is required on the straight seams of the box body, the worker places the box body on top of the positioning bracket 7. The positioning bracket 7 supports and positions the horizontal plate of the box body. Then, the height and angle of the two first support rods 29 are adjusted so that the first support rods 29 can be clamped and fixed on both sides of the metering box body. At this time, the positioning effect of the first support rods 29 on both sides of the box body can ensure the integrity and stability of the weld seam splicing and prevent the spacing between the weld seams from shifting due to the weight of the box body itself. After the position of the first support rods 29 is adjusted, the worker starts the drive mechanism 4 and the welding head 5. The drive mechanism 4 can drive the welding head 5 to move horizontally and weld the seams on the box body. After the welding is completed, the worker can take out the box body.

[0063] When welding is required on the right-angled weld seams of the housing, the worker first removes the screws from the adjusting turntable 12 and the screw connector 15. Then, the two adjusting turntables 12 are rotated 180 degrees. During the rotation of the adjusting turntables 12, the positioning bracket 7 will rotate synchronously on the middle of the housing 2 along with the adjusting turntables 12. After rotation, the adjusting turntables 12 are fixed to the screw connector 15 again with the screws to achieve the fixed effect of the positioning bracket 7. During the angle adjustment of the positioning bracket 7, the worker can use the screw hole 14 to refer to the actual rotation angle of the positioning bracket 7, ensuring the accuracy of the angle adjustment and the convenience of the adjustment process. After the positioning bracket 7 is adjusted, the two right-angled sides of the positioning bracket 7 are at the top. At this time, the housing to be welded is placed on the top of the positioning bracket 7. The positioning bracket 7 can then fix the two right-angled sides of the housing. The right-angled sides are used for support and positioning. Then, the staff adjusts the distance between the two second support rods 32 so that the second support rods 32 can just support the other two right-angled sides on the box body corresponding to the position of the positioning bracket 7. Finally, the height and angle of the first support rod 29 are adjusted so that the first support rod 29 supports the two plates on the box body adjacent to the position of the positioning bracket 7. At this time, with the cooperation of the first support rod 29 and the second support rod 32, the box body can be stably supported, thereby ensuring the integrity and stability of the weld joint during the welding process, and further preventing the spacing between the weld joints from shifting due to the weight of the box body itself. Finally, the staff starts the drive mechanism 4 and the welding head 5. The drive mechanism 4 can drive the welding head 5 to move horizontally and weld the weld joints on the box body. After the welding is completed, the staff can take out the box body.
