Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and more specifically to a welding device for an electric vehicle controller housing. Background Technology

[0002] In the welding process of electric vehicle controller housings, accurate positioning is crucial to ensure the alignment of the sides of each component and the base plate, thus avoiding dimensional deviations or assembly gaps after welding. Electric vehicle controller housings are generally box-shaped structures formed by a base plate and four side plates. Current welding procedures typically involve manually placing each side plate onto the base plate for alignment, followed by spot welding for pre-fixation before formal welding. This method is time-consuming and prone to displacement between the side plates and the base plate, leading to gaps that affect weld quality. Furthermore, this welding method is also quite time-consuming and labor-intensive. Summary of the Invention

A clamping cylinder is embedded in the top surface of the welding frame. A clamping rod is provided on the piston rod of the clamping cylinder, and the clamping rod is movably arranged outside the positioning plate.

[0005] Preferably, the flipping frame is a rectangular plate structure, and grooves are provided on both opposite side walls of the flipping frame. A flat vacuum suction cup is placed in the groove, and multiple slots are provided at intervals on the two opposite openings of the groove. The flipping frame can automatically feed materials under the adsorption of the flat vacuum suction cup before welding.

[0006] Preferably, the clamping rod has an inverted U-shaped structure, with both ends of the U-shaped opening of the clamping rod extending movably into the top surface of the welding frame, and the positioning plates are sequentially and movably arranged in the U-shaped opening of the clamping rod from top to bottom, so as to facilitate the clamping and fixing of the positioning plates used by the clamping rod, thereby facilitating the fixing function when welding the electric vehicle controller housing.

[0007] Preferably, a platform is provided on the top surface of the welding frame, and the platform is set in the U-shaped opening of the clamping rod. The clamping cylinder is embedded in the top surface of the platform. The clamping cylinder drives the clamping rod to clamp and fix the positioning plate used, thereby facilitating the fixing function when welding the electric vehicle controller housing.

[0008] Preferably, the platform has a guide rod vertically arranged at the end away from the clamping cylinder, and the positioning plate is open at the end away from the guide rod. The positioning plate is movably sleeved on the outside of the guide rod, which is beneficial to the stability of the position when multiple positioning plates are stacked from top to bottom.

[0009] Preferably, a stabilizing plate is rotatably hinged to the side wall of the positioning plate away from the opening end, the stabilizing plate comprising: Vertical top plate, which is set at intervals on the side wall of the positioning plate away from the opening end by connecting plates; Storage slots are located on the side wall of the vertical top plate near the positioning plate. The folding plate is movably installed in the storage slot, which facilitates fixing the position of the welded electric vehicle controller housing by stacking the plate and preventing deformation after welding.

[0010] Preferably, the folding plate comprises: The inner walls at both ends of the opening of the storage slot are provided with grooves; The sliding shaft is movably set in the storage groove, and both ends of the sliding shaft along its length are respectively slidably set in two grooves. Plate 1 is mounted on the sliding shaft; Plate 2 is hinged to the end of Plate 1 away from the sliding shaft via a hinge shaft.

[0014] The beneficial effects of the present invention are as follows: 1. The flat vacuum suction cup can adsorb and flip the bottom plate of the electric vehicle controller housing stacked in the feeding tray to complete the feeding. At the same time, the positioning plate can position the side plate of the electric vehicle controller housing, thereby avoiding displacement between the side plate and the bottom plate of the electric vehicle controller housing and improving the welding quality.

[0015] 2. Multiple positioning plates are stacked from top to bottom. The appropriate number can be selected according to the different heights of the side plates in the electric vehicle controller housing, which facilitates the support of the side plates in the electric vehicle controller housing and improves its applicability.

[0016] 3. When it is necessary to fix the side plate in the electric vehicle controller housing, the second plate can be slid to the outside of the storage groove and flipped around the hinge axis so that the second plate and the first plate are distributed in an inverted L shape; this will allow the side plate of the electric vehicle controller housing to be clamped between the second plate and the vertical top plate, thereby preventing deformation of the side plate of the electric vehicle controller housing after welding.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1 like Figures 1 to 4 , Figure 8As shown, the present invention provides a welding device for an electric vehicle controller housing, including a welding frame 1; a tilting groove 2 disposed on the welding frame 1; a tilting frame assembly 3 rotatably disposed within the tilting groove 2; a feeding assembly 4 disposed below the tilting frame assembly 3; two positioning plate assemblies 5 are provided, the two positioning plate assemblies 5 being symmetrically disposed on opposite sides of the tilting groove 2; the tilting frame assembly 3 includes a tilting motor 33 embedded in the inner wall of the tilting groove 2, a tilting frame 31 disposed on the output shaft of the tilting motor 33, the tilting frame 31 being rotatably disposed within the tilting groove 2, wherein the tilting frame 31... Flat vacuum suction cups 32 are provided on both opposite side walls; the feeding assembly 4 includes a lifting cylinder 42 located below the tilting frame 31, and a feeding tray 41 is provided on the piston rod of the lifting cylinder 42. The position of the feeding tray 41 is adapted to the position of the flat vacuum suction cup 32; the positioning plate assembly 5 includes multiple positioning plates 51 that are movably arranged on the top surface of the welding frame 1 from top to bottom. A pressing cylinder 52 is embedded in the top surface of the welding frame 1. A pressing rod 53 is provided on the piston rod of the pressing cylinder 52. The pressing rod 53 is movably arranged outside the positioning plate 51.

[0029] Before welding, multiple materials (the base plate in the electric vehicle controller housing) can be stacked from top to bottom in the feeding tray 41. The lifting cylinder 42 can drive the feeding tray 41 to lift and lower to achieve feeding. The flipping motor 33 drives the flipping frame 31 to flip within the flipping groove 2. When the flat vacuum suction cup 32 on the flipping frame 31 flips to face the material feeding tray 41, the flat vacuum suction cup 32 can adsorb the material (the bottom plate in the electric vehicle controller housing) stacked on the top layer in the material feeding tray 41. After adsorption, the flipping motor 33 drives the flipping frame 31 to flip again, thereby completing the feeding of the material (the bottom plate in the electric vehicle controller housing). Then, other materials (the various side plates in the electric vehicle controller housing) are placed in their corresponding positions in sequence to complete the welding of the electric vehicle controller housing.

[0030] Based on the height of the electric vehicle controller housing, a corresponding number of positioning plates 51 are stacked sequentially from top to bottom on the top surface of the welding frame 1. Then, the clamping cylinder 52 is activated to drive the clamping rod 53, which can clamp and fix the positioning plates 51 stacked sequentially from top to bottom. This facilitates the support of other materials (side plates in the electric vehicle controller housing) through the positioning plates 51, making welding operations easier.

[0031] Example 2 Based on Example 1, such as Figures 1 to 2 , Figure 8As shown, the flipping frame 31 is a rectangular plate structure, and grooves 311 are provided on both opposite side walls of the flipping frame 31. The flat vacuum suction cup 32 is set in the groove 311, and multiple slots 312 are provided at intervals on the two opposite openings of the groove 311. When the flipping frame 31 flips, the material (the bottom plate in the electric vehicle controller housing) placed in the feeding tray 41 can be adsorbed into the groove 311 by the adsorption of the flat vacuum suction cup 32, realizing automatic circulating feeding. (At the same time, the opposite ends of the side plate in the electric vehicle controller housing can be respectively inserted into the slots 312 at the corresponding positions, which can improve the positional accuracy and stability between the side plate and the bottom plate in the electric vehicle controller housing. The bottom surface of the slot 312 can be on the same plane as the top surface of the bottom plate in the electric vehicle controller housing adsorbed by the flat vacuum suction cup 32, so that the side plate and the bottom plate in the electric vehicle controller housing can contact each other, which is convenient for welding.) This improves the welding efficiency.

[0032] Example 3 Based on Example 1, such as Figures 1 to 4 As shown, the clamping rod 53 has an inverted U-shaped structure. The two ends of the U-shaped opening of the clamping rod 53 extend movably into the top surface of the welding frame 1, and the positioning plates 51 are movably arranged in the U-shaped opening of the clamping rod 53 from top to bottom. A platform 11 is provided on the top surface of the welding frame 1. The platform 11 is arranged in the U-shaped opening of the clamping rod 53, and the clamping cylinder 52 is embedded in the top surface of the platform 11. A guide rod 12 is vertically arranged at the end of the platform 11 away from the clamping cylinder 52. The end of the positioning plate 51 away from the guide rod 12 is open, and the positioning plate 51 is movably sleeved on the outside of the guide rod 12. The outer peripheral wall of the guide rod 12 is in contact with the inner peripheral wall of the opening of the positioning plate 51.

[0033] After multiple positioning plates 51 are stacked sequentially from top to bottom as needed (the guide rod 12 can play a certain limiting role, which helps to keep the position of each positioning plate 51 stacked sequentially from top to bottom stable), the clamping cylinder 52 is activated to drive the clamping rod 53 to move towards the top surface of the welding frame 1, so that the bottom of the U-shaped opening of the clamping rod 53 abuts against the topmost positioning plate 51, thereby clamping and fixing the multiple positioning plates 51 stacked from top to bottom. That is, the positioning plates 51 can support the side plates at the corresponding positions in the electric vehicle controller housing, which facilitates the fixing effect when welding the electric vehicle controller housing.

[0034] When the side panel in the electric vehicle controller housing has a right-angle wavy structure, the positioning plate 51 at the corresponding position can be moved horizontally so that the opposite end of the opening end of the positioning plate 51 abuts against the side panel in the electric vehicle controller housing, which is beneficial to the accurate positioning of the side panel after it is placed in the electric vehicle controller housing.

[0035] Example 4 Based on Example 1, such as Figure 1 , Figures 3 to 7 As shown, a stabilizing plate 54 is rotatably hinged to the side wall of the positioning plate 51 away from the opening end. The stabilizing plate 54 includes a vertical top plate 541, which is spaced apart on the side wall of the positioning plate 51 away from the opening end via connecting plates 542. A storage slot 543 is provided on the side wall of the vertical top plate 541 near the end of the positioning plate 51. A folding plate 544 is movably disposed within the storage slot 543. The folding plate 544 includes a sliding groove 5441, and sliding grooves 5441 are provided on the inner walls at both ends of the opening of the storage slot 543. A sliding shaft 5442 is movably disposed within the storage slot 543, and the sliding shaft 544... 2. The two ends along the length direction are respectively slidably set in two sliding grooves 5441; plate one 5443 is set on sliding shaft 5442; plate two 5444 is hinged to the end of plate one 5443 away from sliding shaft 5442 through hinge shaft 5445, and both plate one 5443 and plate two 5444 are movably set in storage groove 543; a fixing screw 5446 is threaded through plate two 5444, and an internal threaded hole 5447 adapted to the fixing screw 5446 is provided in storage groove 543. The fixing screw 5446 movably passes through plate two 5444 and is threadedly connected to the internal threaded hole 5447.

[0036] When it is necessary to fix the side plate in the electric vehicle controller housing, the position of the sliding shaft 5442 can be adjusted by sliding it in the sliding groove 5441 (sliding the sliding shaft 5442 towards the top of the storage groove 543), so that the positions of plate one 5443 and plate two 5444 can be adjusted at the same time. After plate two 5444 is slid to the outside of the storage groove 543, plate two 5444 can be flipped with the hinge shaft 5445 as the axis, so that plate two 5444 and plate one 5443 are distributed in an inverted L shape. Then tighten the fixing screw 5446, which is threaded through plate two 5444 and the internal threaded hole 5447. At this time, the side plate of the electric vehicle controller housing is clamped between plate two 5444 and the vertical top plate 541, which can prevent the side plate of the electric vehicle controller housing from deforming after welding.

[0037] When plate 2 5444 is not needed, plate 1 5443 and plate 2 5444 can be slidably stored in the storage slot 543 (at this time, when welding the side plate of the electric vehicle controller housing, the side plate of the electric vehicle controller housing can be made to abut against the vertical top plate 541).

[0038] Example 5 Based on Example 1, such as Figure 1 As shown, each clamping rod 53 has at least two positioning plates 51 in its U-shaped opening; the number of positioning plates 51 can be stacked sequentially from top to bottom according to the height of the electric vehicle controller housing, which improves the versatility of application; and it is also convenient to support the electric vehicle controller housing during welding by means of the positioning plates 51.

[0039] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
