Description

Technical Field

[0001] This utility model belongs to the field of charger technology, specifically relating to a support device for welding large electrolytic aluminum shells. Background Technology

[0002] Electrolytic aluminum housings are structural shell components made from electrolytic aluminum (high-purity aluminum and aluminum alloys produced through electrolysis) using processes such as die casting, extrusion, stamping, or welding. They are primarily used to enclose and protect internal components or support specific functional modules. Their design must consider material properties, structural strength, heat dissipation performance, and application requirements. They are widely used in electronic equipment, new energy, and the automotive industry. When welding and assembling electrolytic aluminum housings, welding is generally required between the base plate and the side plates that form the side walls, as well as between adjacent side plates. For heavier or larger plates, support mechanisms are needed to position and support the plates to facilitate welding.

[0003] Existing large electrolytic aluminum shell support devices typically use fixed frames with clamps for support. However, these structures generally have the following problems: the clamping components have a single fixing method, making it difficult to adapt to various shell structures; they lack multi-dimensional adjustment mechanisms, making it impossible to finely adjust the assembly gap of the shell; the side plate clamping structure has low adjustment freedom and lacks pitch angle adjustment function, making it difficult to adjust the clamping angle according to different process requirements during welding, which can easily lead to positioning deviation and affect welding quality.

[0004] Therefore, there is an urgent need to design a welding support device for electrolytic aluminum shells with multi-axis adjustment function, which can realize precise clamping and posture adjustment of the base plate and side plate, so as to improve the adaptability and ease of operation of welding process and solve the problems of difficult adjustment and poor versatility of existing support structures. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide a support device for welding large electrolytic aluminum shells. This device not only meets the stable support requirements of large electrolytic aluminum shells during plate assembly welding, but also achieves high adaptability, high-precision positioning, and reliable clamping for different shell shapes and structures through the coordinated operation of multiple adjustment mechanisms. This effectively improves welding quality and reduces the difficulty of manual adjustment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a support device for welding large electrolytic aluminum shells, comprising a base, a bracket rotatably mounted on the top of the base, a support platform mounted on the top of the bracket, an X-axis guide groove and a Y-axis guide groove extending through the top and bottom of the support platform, an X-axis bidirectional screw and a Y-axis bidirectional screw rotatably mounted on the inner side of the bracket, sliders slidably mounted on the inner sides of the X-axis guide groove and the Y-axis guide groove, a base plate support clamp mounted on the top of the slider, a mounting plate connected to one side of the base plate support clamp, and a mounting plate mounted on the top of the mounting plate. The device includes a side plate support clamping device, which comprises a lifting and adjusting mechanism fixed to the top of the mounting plate. A support beam is mounted on the top of the lifting and adjusting mechanism. A guide slide rod and a second transmission screw are installed through and between the two sides of the support beam. One end of the guide slide rod is fixedly connected to an L-shaped plate. The L-shaped plate is also rotatably connected to one end of the second transmission screw. A first bearing seat is provided on one side of the L-shaped plate. The first bearing seat is connected to the side plate clamping mechanism through a rotating seat. A pitch adjustment mechanism is connected to the top of the L-shaped plate and the top of the side plate clamping mechanism.

[0007] The beneficial effects of this utility model are as follows: This device has multi-dimensional operation capabilities such as support platform rotation adjustment, clamping size adjustment for the base plate, vertical height adjustment for the side plate, and clamping angle adjustment. It can not only meet the stable support requirements of large electrolytic aluminum shells during plate assembly welding, but also achieve high adaptability, high precision positioning and reliable clamping for different shell shapes and structures through the coordinated operation of multiple adjustment mechanisms, thereby effectively improving welding quality and reducing the difficulty of manual adjustment.

[0008] To drive the support platform to rotate:

[0009] As a further improvement to the above technical solution: a motor is installed under the top plate of the base, and the output end of the motor is connected to the bracket.

[0010] The beneficial effects of this improvement are as follows: During the welding process, the motor-driven bracket installed on the base can be controlled to rotate around the central axis, so that the bracket drives the top support platform together with the supporting and fixed electrolytic aluminum shell to adjust the overall orientation, so as to meet the requirements of changing the welding position during the welding process, and so that each welding position of the electrolytic aluminum shell can be quickly adjusted to the position facing the worker.

[0011] To accommodate the clamping and fixing of the base plate portion of electrolytic aluminum shells of different lengths and widths:

[0012] As a further improvement to the above technical solution: the slider in the X-guide groove is threadedly connected to the X-direction bidirectional screw, and the slider in the Y-guide groove is threadedly connected to the Y-direction bidirectional screw.

[0013] The beneficial effects of this improvement are as follows: by rotating the X-axis bidirectional screw and the Y-axis bidirectional screw via the handwheel, the operator can drive the two sets of sliders in the X-axis guide groove to move towards or away from each other, and drive the two sets of sliders in the Y-axis guide groove to move towards or away from each other, thereby adjusting the distance between the left and right sets of base plate support clamps and the distance between the front and rear sets of base plate support clamps, thus satisfying the clamping and fixing of the base plate part of electrolytic aluminum shells of different lengths and widths.

[0014] For the horizontal adjustment of the side plate clamping mechanism:

[0015] As a further improvement to the above technical solution: the guide slide rod is slidably connected to the support beam, and the second transmission screw is threadedly connected to the support beam.

[0016] The beneficial effects of this improvement are as follows: by rotating the second transmission screw through the handwheel, the L-shaped plate can be driven to move horizontally under the guidance of the guide slide rod through the transmission between the second transmission screw and the support beam, thereby realizing the adjustment of the side plate clamping mechanism in the horizontal direction.

[0017] To meet the support requirements of side panels at different heights:

[0018] As a further improvement to the above technical solution: the lifting and adjusting mechanism includes a hollow support column fixed to the top of the mounting plate, a telescopic column inserted inside the hollow support column, a first transmission screw rotatably installed inside the hollow support column, a first bevel gear fixedly sleeved on the outer side of the first transmission screw, a rotating shaft passing through and rotatably installed between the inner and outer sides of the hollow support column, one end of the rotating shaft located on the inner side of the hollow support column being connected to a second bevel gear, the second bevel gear meshing with the first bevel gear, and the top of the telescopic column being connected to a support beam.

[0019] The beneficial effects of this improvement are as follows: by rotating the handwheel to drive the shaft to rotate, the inner second bevel gear is driven to rotate. Through the meshing transmission between the second bevel gear and the first bevel gear, the first transmission screw is driven to rotate, thereby enabling the telescopic column that is threaded with it to achieve vertical lifting and lowering movement, completing the height adjustment operation of the support beam, thereby driving the side plate clamping mechanism to adjust its height to meet the support requirements of side plates of different heights.

[0020] For clamping and supporting the positioning of the side plates of the electrolytic aluminum shell:

[0021] As a further improvement to the above technical solution: the side plate clamping mechanism includes a side plate clamping seat connected to the rotating shaft, and electric telescopic rods are provided on both sides of the side plate clamping seat. The piston rod end of the electric telescopic rod is connected to the clamping plate.

[0022] The beneficial effects of this improvement are as follows: Before clamping the side plate, the side plate clamping seat is adjusted and moved to the outside of the top edge of the side plate, and its angle is adjusted so that the clamping plate is parallel to the plate surface of the side plate. The electric telescopic rod is controlled to extend the piston rod, and the piston rod pushes the clamping plate at its end to clamp inward, thereby achieving clamping, support and positioning of the electrolytic aluminum shell side plate.

[0023] For pitch adjustment of the side plate clamping mechanism:

[0024] As a further improvement to the above technical solution: the pitch adjustment mechanism includes a second bearing seat installed above the L-shaped plate and a third bearing seat installed above the side plate clamping seat. One side of the third bearing seat is rotatably connected to the internal threaded rod, and one side of the second bearing seat is rotatably connected to the fourth bearing seat. A third transmission screw is rotatably installed on the inner side of the fourth bearing seat, and one end of the third transmission screw is threadedly connected to the internal threaded rod.

[0025] The beneficial effects of this improvement are as follows: The top of the L-shaped plate and the top of the side plate clamping mechanism are connected together by a pitch adjustment mechanism. This mechanism forms a linkage fulcrum through the second bearing seat on the L-shaped plate and the third bearing seat on the side plate clamping seat. The operator can drive the third transmission screw to rotate by turning the handwheel. Through the transmission between the screw and the internal thread of the internal thread rod, the internal thread rod is moved, changing the distance between the internal thread rod and the fourth bearing seat. This pulls the side plate clamping mechanism to rotate through the cooperation of the first bearing seat and the rotating seat, thereby realizing pitch adjustment.

[0026] As a further improvement to the above technical solution: a handwheel is installed at one end of the X-direction bidirectional screw, the Y-direction bidirectional screw, the rotating shaft, the second transmission screw, and the third transmission screw.

[0027] The handwheel is used to manually rotate the X-axis bidirectional screw, the Y-axis bidirectional screw, the shaft, the second transmission screw, and the third transmission screw.

[0035] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0036] like Figure 1-5 As shown, a support device for welding large electrolytic aluminum shells includes a base 1, a bracket 3 rotatably mounted on the top of the base 1, a support platform 4 mounted on the top of the bracket 3, an X-guide groove 5 and a Y-guide groove 6 extending through the top and bottom of the support platform 4, an X-direction bidirectional screw 7 and a Y-direction bidirectional screw 8 rotatably mounted on the inner side of the bracket 3, and sliders 10 slidably mounted on the inner sides of both the X-guide groove 5 and the Y-guide groove 6, a base plate support clamp 11 mounted on the top of the slider 10, a mounting plate 12 connected to one side of the base plate support clamp 11, and a side plate support clamping device 13 mounted on the top of the mounting plate 12. The side plate support clamping device 13 includes a lifting adjustment mechanism fixed to the top of the mounting plate 12. A support beam 20 is installed on the top of the lifting adjustment mechanism. A guide slide rod 21 and a second transmission screw 22 are installed through and installed between the two sides of the support beam 20. One end of the guide slide rod 21 is fixedly connected to an L-shaped plate 23. The L-shaped plate 23 is also rotatably connected to one end of the second transmission screw 22. A first bearing seat 24 is provided on one side of the L-shaped plate 23. The first bearing seat 24 is connected to the side plate clamping mechanism through a rotating seat 25. The top of the L-shaped plate 23 and the top of the side plate clamping mechanism are connected together to a pitch adjustment mechanism.

[0037] This device has multi-dimensional operational capabilities, including support platform rotation adjustment, clamping size adjustment for the base plate, vertical height adjustment for the side plates, and clamping angle adjustment. It can not only meet the stable support requirements of large electrolytic aluminum shells during plate assembly welding, but also achieve high adaptability, high-precision positioning, and reliable clamping for different shell shapes and structures through the coordinated operation of multiple adjustment mechanisms, thereby effectively improving welding quality and reducing the difficulty of manual adjustment.

[0038] A motor 2 is installed below the top plate of the base 1, and the output end of the motor 2 is connected to the bracket 3.

[0039] During the welding process, the motor 2 installed on the base 1 can be controlled to drive the bracket 3 to rotate around the central axis, so that the bracket 3 drives the top support platform 4 together with the supporting and fixed electrolytic aluminum shell to adjust the overall orientation, so as to meet the requirements of changing the welding position during the welding process, and so that each welding position of the electrolytic aluminum shell can be quickly adjusted to the position facing the worker.

[0040] The slider 10 in the X-guide groove 5 is threadedly connected to the X-direction bidirectional screw 7, and the slider 10 in the Y-guide groove 6 is threadedly connected to the Y-direction bidirectional screw 8.

[0041] The operator can rotate the X-direction bidirectional screw 7 and the Y-direction bidirectional screw 8 by handwheel 9, which can drive the two sets of sliders 10 in the X-direction guide groove 5 to move towards or away from each other, and drive the two sets of sliders in the Y-direction guide groove 6 to move towards or away from each other, thereby adjusting the distance between the left and right sets of base plate support clamps 11 and the distance between the front and rear sets of base plate support clamps 11, so as to meet the clamping and fixing of the base plate part of electrolytic aluminum shells of different lengths and widths.

[0042] The guide slide rod 21 is slidably connected to the support beam 20, and the second transmission screw 22 is threadedly connected to the support beam 20.

[0043] By rotating the second transmission screw 22 through the handwheel 9, the L-shaped plate 23 can be driven to move horizontally under the guidance of the guide slide rod 21 through the transmission between the second transmission screw 22 and the support beam 20, thereby realizing the adjustment of the side plate clamping mechanism in the horizontal direction.

[0044] The lifting and adjusting mechanism includes a hollow support column 14 fixed to the top of the mounting plate 12. A telescopic column 15 is inserted and installed inside the hollow support column 14. A first transmission screw 16 is rotatably installed inside the hollow support column 14. A first bevel gear 17 is fixedly sleeved on the outer side of the first transmission screw 16. A rotating shaft 19 is rotatably installed between the inner and outer sides of the hollow support column 14. One end of the rotating shaft 19 located on the inner side of the hollow support column 14 is connected to a second bevel gear 18. The second bevel gear 18 meshes with the first bevel gear 17. The top of the telescopic column 15 is connected to the support beam 20.

[0045] By rotating the handwheel 9, the shaft 19 is driven to rotate, which in turn drives the inner second bevel gear 18 to rotate. The meshing transmission between the second bevel gear 18 and the first bevel gear 17 drives the first transmission screw 16 to rotate, thereby enabling the telescopic column 15, which is threaded with it, to achieve vertical lifting and lowering movement, completing the height adjustment operation of the support beam 20. This, in turn, drives the side plate clamping mechanism to adjust its height to meet the support requirements of side plates of different heights.

[0046] The side plate clamping mechanism includes a side plate clamping seat 26 connected to the rotating seat 25. Both sides of the side plate clamping seat 26 are provided with electric telescopic rods 27, and the piston rod end of the electric telescopic rod 27 is connected to the clamping plate 28.

[0047] Before clamping the side plate, adjust and move the side plate clamping seat 26 to the outside of the top edge of the side plate, and adjust its angle so that the clamping plate 28 is parallel to the surface of the side plate. Control the electric telescopic rod 27 to extend the piston rod. The piston rod pushes the clamping plate 28 at its end to clamp inward, thereby achieving clamping, support and positioning of the electrolytic aluminum shell side plate.

[0048] The pitch adjustment mechanism includes a second bearing seat 29 mounted above the L-shaped plate 23 and a third bearing seat 30 mounted above the side plate clamping seat 26. One side of the third bearing seat 30 is rotatably connected to the internal threaded rod 31, and one side of the second bearing seat 29 is rotatably connected to the fourth bearing seat 32. A third transmission screw 33 is rotatably mounted on the inner side of the fourth bearing seat 32, and one end of the third transmission screw 33 is threadedly connected to the internal threaded rod 31.

[0049] The top of the L-shaped plate 23 and the top of the side plate clamping mechanism are connected to a pitch adjustment mechanism. This mechanism forms a linkage fulcrum through the second bearing seat 29 on the L-shaped plate 23 and the third bearing seat 30 on the side plate clamping seat 26. The operator can drive the third transmission screw 33 to rotate by turning the handwheel 9. Through the transmission between the screw and the internal thread of the internal thread rod 31, the internal thread rod 31 is moved, changing the distance between the internal thread rod 31 and the fourth bearing seat 32. This pulls the side plate clamping mechanism to rotate through the cooperation of the first bearing seat 24 and the rotating seat 25, thereby realizing pitch adjustment.

[0050] A handwheel 9 is installed at one end of each of the X-direction bidirectional screw 7, the Y-direction bidirectional screw 8, the rotating shaft 19, the second transmission screw 22, and the third transmission screw 33.

[0051] The handwheel 9 is used to manually rotate the X-direction bidirectional screw 7, the Y-direction bidirectional screw 8, the rotating shaft 19, the second transmission screw 22, and the third transmission screw 33.

[0052] The working principle and usage process of this utility model: During use, an X-guide groove 5 and a Y-guide groove 6 are provided between the top and bottom of the support platform 4. Slider 10s are slidably installed inside both sets of guide grooves. The slider 10 in the X-guide groove 5 is threadedly engaged with the X-direction bidirectional screw 7, and the slider 10 in the Y-guide groove 6 is threadedly engaged with the Y-direction bidirectional screw 8. The operator rotates the X-direction bidirectional screw 7 and the Y-direction bidirectional screw 8 via the handwheel 9, which drives the two sets of sliders 10 in the X-guide groove 5 to move towards or away from each other, and also drives the two sets of sliders in the Y-guide groove 6 to move towards or away from each other. This adjusts the distance between the left and right sets of base plate support clamps 11 and the distance between the front and rear sets of base plate support clamps 11, thereby meeting the needs of different lengths and... The bottom plate portion of the wide electrolytic aluminum shell is clamped and fixed. A mounting plate 12 is fixed to one side of the bottom plate support clamp 11. A side plate support clamping device 13 is connected to the top of the mounting plate 12. This device is used to support and clamp the side plate portion of the shell, ensuring that the side plate portion of the shell can stably contact the edge of the bottom plate portion during welding, preventing displacement or deformation during welding. Specifically, the side plate support clamping device 13 includes a hollow support column 14 fixed to the mounting plate 12, with a telescopic column 15 inserted inside. Rotating the handwheel 9 drives the rotating shaft 19 to rotate, causing the inner second bevel gear 18 to rotate. The meshing transmission between the second bevel gear 18 and the first bevel gear 17 drives the first transmission screw 16 to rotate, thereby enabling it to rotate. The threaded telescopic column 15 achieves vertical lifting and lowering movement, completing the height adjustment operation of the supporting beam 20, thereby driving the side plate clamping mechanism to adjust its height to meet the support requirements of side plates of different heights. The supporting beam 20 is equipped with a guide slide rod 21 and a second transmission screw 22, wherein the guide slide rod 21 is slidably connected to the beam, and the second transmission screw 22 is threadedly connected to the beam. By rotating the second transmission screw 22 through the handwheel 9, the L-shaped plate 23 is driven to move horizontally under the guidance of the guide slide rod 21 through the transmission between the second transmission screw 22 and the supporting beam 20, realizing the adjustment of the side plate clamping mechanism in the horizontal direction. The L-shaped plate 23 is rotatably connected to the side plate clamping mechanism through the cooperation of the first bearing seat 24 and the rotating seat 25. The top of the L-shaped plate 23 is connected to the side plate clamping mechanism. The top of the plate clamping mechanism is connected to a pitch adjustment mechanism. This mechanism forms a linkage fulcrum through the second bearing seat 29 on the L-shaped plate 23 and the third bearing seat 30 on the side plate clamping seat 26. The operator can drive the third transmission screw 33 to rotate by turning the handwheel 9. Through the transmission between the screw and the internal thread of the internal thread rod 31, the internal thread rod 31 is moved, changing the distance between the internal thread rod 31 and the fourth bearing seat 32. This pulls the side plate clamping mechanism to rotate through the cooperation of the first bearing seat 24 and the rotating seat 25, realizing pitch adjustment. Through the horizontal and pitch adjustment functions of the side plate clamping mechanism, the side plate clamping mechanism can not only clamp and support vertical side plates, but also clamp and support inclined side plates.This is particularly suitable for welding shells with trapezoidal cross-sections. The side plate clamping mechanism includes a side plate clamping seat 26 and an electric telescopic rod 27 installed on its side. Before clamping the side plate, the side plate clamping seat 26 is moved to the outside of the top edge of the side plate through the aforementioned adjustment function, and its angle is adjusted so that the clamping plate 28 is parallel to the plate surface of the side plate. The electric telescopic rod 27 is controlled to extend the piston rod. The piston rod pushes the clamping plate 28 at its end to clamp inward, thereby achieving clamping support and positioning of the electrolytic aluminum shell side plate. The lifting adjustment mechanism is used to ensure that the bottom of the electrolytic aluminum shell side plate is in contact with the base plate. During the welding process, the motor 2 mounted on the base 1 drives the bracket 3 to rotate around the central axis. This causes the bracket 3 to move the top support platform 4, along with the supporting and fixed electrolytic aluminum shell structure, to adjust the overall orientation. This meets the requirements for changing welding positions during the welding process, allowing each welding position of the electrolytic aluminum shell to be quickly adjusted to face the worker. In summary, this device has multi-dimensional operational capabilities, including support platform rotation adjustment, clamping size adjustment for the base plate, vertical height adjustment for the side plates, and clamping angle adjustment. It not only meets the stable support requirements of large electrolytic aluminum shells during plate assembly welding but also achieves high adaptability, high-precision positioning, and reliable clamping for different shell shapes and structures through the coordinated operation of multiple adjustment mechanisms. This effectively improves welding quality and reduces the difficulty of manual adjustment.
