Description

Technical Field

[0001] This application relates to the technical field of welding equipment, and in particular to a welding equipment for an electric box body. Background Art

[0002] New energy vehicles are an environmentally friendly type of vehicle powered by electricity. During production, multiple storage batteries are installed on the vehicle body, and the storage batteries supply energy to the vehicle. When installing the storage batteries, an electric box is usually installed on the vehicle body. The inside of the electric box has a grid-like structure, and the storage batteries are respectively installed in the grids of the electric box.

[0003] Currently, welding is generally used for connection and fixation during the production of electric boxes. Refer to Figure 1 , an electric box structure, including an outer plate 1 and a partition plate 2. The outer plate 1 is composed of a long plate 11 and a short plate 12. Before welding, the long plate 11 and the short plate 12 are symmetrically placed respectively, and the short plate 12 is abutted and clamped by two long plates 11, so that the long plate 11 and the short plate 12 enclose a frame structure. Then, the partition plate 2 is placed inside the frame, and finally, the connection points are welded and fixed by manual welding or a welding robot.

[0004] Regarding the above related technologies, the inventor believes that there are the following defects: during placement, if the outer plate 1 and the partition plate 2 are accidentally touched and shifted, the quality of the finished electric box after welding and fixation is likely to be affected. Summary of the Invention

[0005] In order to improve the quality of the finished electric box, this application provides a welding equipment for an electric box body.

[0006] This application provides a welding equipment for an electric box body, adopting the following technical solutions:

[0007] A welding equipment for an electric box body includes a welding table and a welding arm arranged on the working surface of the welding table. Among them, the working surface includes a central area and a peripheral area surrounding the central area;

[0008] The equipment further includes a plurality of abutting plates and clamping plates slidably connected to the working surface;

[0009] The abutting plates are evenly distributed in the peripheral area, and the abutting surfaces of the abutting plates face the central area. A driving member is connected to the non-abutting surface of each abutting plate, and the driving member is used to control the abutting plate to move in a direction close to or away from the central area;

[0010] Each abutting plate is provided with a corresponding clamping plate, and the two are linked;

[0011] The clamping plates are distributed in the central area, and the clamping surfaces of the clamping plates are arranged opposite to each other in pairs to form a clamping space. Each clamping space is at least located between two abutting plates.

[0012] By adopting the above technical solution, before welding, the driving member is used to drive the abutting plate to move, so that the abutting plate abuts against the electric box body for preliminary fixing. At the same time, when the abutting plate moves, the clamping plate is linked, fixed and corrected. Finally, the welding arm can be used for welding. The whole welding process is simple, which can reduce the possibility of deviation caused by accidental touch before welding, and is beneficial to improving the quality of the electric box body after welding.

[0013] Optionally, fixing plates that can be flipped towards or away from the welding table are respectively hinged to one side of the clamping plate away from the welding table. The clamping plate is provided with a control component for controlling the flipping of the fixing plates. When the clamping plate is away from the driving member, the control component controls the fixing plates to flip to abut against the side of the workpiece to be welded away from the welding table.

[0014] By adopting the above technical solution, when the abutting plate and the clamping plate move, the control component controls the flipping of the fixing plates, and cooperates with the welding table to clamp the electric box body, reducing the possibility of deviation of the outer plate and the partition plate.

[0015] Optionally, the driving member is a driving cylinder. The driving cylinders are in one-to-one correspondence with the abutting plates. The driving cylinders are fixed to the welding table, and the abutting plates are fixed to the piston rods of the driving cylinders.

[0016] By adopting the above technical solution, when in use, the driving cylinder drives the abutting plate to move, so that the abutting plate can approach or move away from the outer plate.

[0017] Optionally, a linkage bar is slidably arranged in the welding table. The linkage bar is respectively connected to one side of the abutting plate and the clamping plate close to the welding table.

[0018] By adopting the above technical solution, when the abutting plate moves, the clamping plate is linked through the linkage bar, which is beneficial to driving the clamping plate to approach or move away from the partition plate.

[0019] Optionally, the control assembly includes a control rope, a control torsion spring, and a control post. A through hole parallel to the sliding direction of the clamping plate is formed in the middle of the clamping plate. The control post slides in the through hole and protrudes out of the through hole in the direction away from the abutting plate. A hinge shaft is rotatably connected to the side of the clamping plate away from the welding table, and the fixing plate is fixed to the hinge shaft. The control torsion spring is sleeved on the hinge shaft and drives the fixing plate to flip away from the welding table. The control rope slidably passes through the clamping plate. One end of the control rope is fixed to the hole wall of the through hole, and the control rope abuts against one end of the control post close to the driving cylinder. The control rope is wound around the hinge shaft and the other end is fixed to the hinge shaft. When the control post abuts against the partition plate, the control post slides in the direction of the driving cylinder, so that the control rope drives the hinge shaft to rotate until the fixing plate abuts against the partition plate.

[0020] By adopting the above technical solution, during use, the control rope is pulled by the control post, so that the control rope is disengaged from the hinge shaft, which is beneficial to driving the fixing plate to flip towards the welding table. At the same time, when the control post pulls the control rope, the control torsion spring drives the fixing plate to flip in the opposite direction, driving the control rope to wind back around the hinge shaft.

[0021] Optionally, a limiting block is arranged on the hole wall of the through hole, and a limiting groove for the limiting block to slide is formed on the outer peripheral side of the control post.

[0022] By adopting the above technical solution, the limiting block slides in the limiting groove, reducing the possibility of the control post disengaging from the through hole.

[0023] Optionally, the welding table includes a pedestal and pedestal columns. The pedestal columns are arranged at the four corners of the edge of the pedestal, and the pedestal is inclined.

[0024] By adopting the above technical solution, the pedestal is inclined, so that the welding slag falling on the pedestal can slide down along the pedestal and drop off.

[0025] Optionally, a rotating shaft is rotatably connected to the clamping plate, and a power assembly for driving the rotating shaft to rotate when the clamping plate approaches or moves away from the driving member is arranged on the clamping plate. A plurality of rubber columns are evenly spaced on the outer peripheral side of the rotating shaft, and the rubber columns knock on the pedestal when the rotating shaft rotates.

[0026] By adopting the above technical solution, the power assembly drives the rotating shaft to rotate, so that the rubber columns can knock on the pedestal to generate vibration, shaking off the welding slag adhering to the welding table after welding, and shaking the welding slag again before the next welding, further reducing the amount of welding slag adhering to the welding table.

[0027] Optionally, the power assembly includes a power gear and a power rack. The power rack is arranged on the pedestal, the power gear is arranged on the rotating shaft, and the power gear meshes with the power rack.

[0028] By adopting the above technical solution, the driving gear meshes with the driving rack to enable the rotation shaft to rotate when the abutting plate and the clamping plate slide.

[0029] Optionally, a cavity is formed in the pedestal.

[0030] By adopting the above technical solution, the propagation effect of vibration is improved.

[0031] In summary, the present application includes at least one of the following beneficial effects:

[0032] 1. The outer plate and the partition plate are fixed by the abutting plate and the clamping plate respectively, and at the same time, the control assembly controls the flipping of the fixing plate, so that the fixing plate cooperates with the welding table to clamp the electric box body, reducing the possibility of the outer plate and the partition plate being accidentally touched and shifted before welding, and greatly improving the quality of the electric box body after welding;

[0033] 2. When the abutting plate and the clamping plate move, the power assembly drives the rotation shaft to rotate, so that the rubber column knocks on the welding table, which can reduce the amount of residual welding slag on the welding table and reduce the possibility of the outer plate and the partition plate being shifted due to the influence of the welding slag when placed.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0040] The following will further elaborate on this application in conjunction with the attached Figure 2-5 drawings for a more detailed description.

[0041] An embodiment of this application discloses a welding device for an electric box housing. Refer to Figure 2 , the welding device for the electric box housing includes a welding table 3 and a welding arm 33. The welding table 3 is composed of a pedestal 31 and a table column 32. There are multiple table columns 32 which are respectively fixed at the four corners of the edge of the pedestal 31. The pedestal 31 is inclined, such that the angle between the surface of the side of the pedestal 31 away from the ground and the ground is set as an acute angle. The welding arm 33 is fixed on the pedestal 31, and welding is performed through the welding arm 33.

[0042] Refer to Figure 2 and Figure 3 , a contact plate 5 and a clamping plate 4 are slidably arranged on the pedestal 31,

[0043] the contact plate 5 corresponds to the outer plate 1 of the electric box, the clamping plate 4 corresponds to the partition plate 2 of the electric box, and the sliding ranges of the contact plate 5 and the clamping plate 4 are restricted according to the positions of the outer plate 1 and the partition plate 2, such that the contact plate 5 and the clamping plate 4 can respectively contact the outer plate 1 and the partition plate 2. There are multiple groups of contact plates 5, each group of contact plates 5 corresponds to one outer plate 1, each group of contact plates 5 has multiple ones and slides evenly spaced on the side of the pedestal 31 away from the table column 32, and the two groups of contact plates 5 corresponding to the long plate 11 correspond to each other, and the two groups of contact plates 5 corresponding to the short plate 12 correspond to each other. The pedestal 31 is provided with a driving member for driving the contact plate 5 to approach or move away from the outer plate 1.

[0044] Refer to Figure 2 , the driving member is a driving cylinder 34. The driving cylinder 34 corresponds to the contact plate 5 one by one and is fixed on the pedestal 31. The driving cylinder 34 is connected to an external air source, and the contact plate 5 is fixed to the piston rod of the driving cylinder 34. The driving cylinders 34 corresponding to the relatively two groups of contact plates 5 are connected to the same air source, and the relative driving cylinders 34 are controlled by controlling the air source to achieve simultaneous forward strokes or reverse strokes. When in use, start the forward stroke of the driving cylinder 34, the piston rod drives the contact plate 5 to move towards the outer plate 1 until it contacts the outer plate 1. At this time, the contact plates 5 corresponding to the relatively two outer plates 1 cooperate with each other, such that the two long plates 11 clamp the two short plates 12 and the partition plate 2, and the two short plates 12 clamp the partition plate 2 perpendicular to the short plate 12; when the reverse stroke of the driving cylinder 34 is started, the piston rod drives the contact plate 5 to move away from the outer plate 1.

[0045] Before welding, one of the long plates 11 can be placed on the abutting plate 5 located below first, then the two short plates 12 and the partition plate 2 are placed, and then the long plate 11 located above is placed. Finally, the driving cylinders 34 corresponding to the upper and lower abutting plates 5 are started first, so that the two long plates 11 can cooperate with each other to clamp the short plates 12 and the partition plate 2 first. After that, the driving cylinders 34 corresponding to the two short plates 12 are started, so that the short plates 12 clamp the partition plate 2. At this time, the long plates 11, the short plates 12 and the partition plate 2 are initially fixed. If the long plates 11, the short plates 12 and the partition plate 2 are offset at this time, manual adjustment can be made.

[0046] See Figure 2 and Figure 3 , the pedestal 31 is provided with a linkage member. During use, the clamping plate 4 and the abutting plate 5 are linked through the linkage member, so that when the abutting plate 5 abuts against the outer plate 1, the abutting plate 5 drives the corresponding clamping plate 4 to move away from the driving cylinder 34. At this time, the clamping plates 4 cooperate with each other to clamp the partition plate 2, fixing the partition plate 2 and correcting the position of the partition plate 2 at the same time.

[0047] See Figure 4 and Figure 5 , the linkage member is a linkage bar 35. There are multiple linkage bars 35 and they correspond to the abutting plates 5 one by one. The pedestal 31 is provided with a sliding groove 351, and the extending direction of the sliding groove 351 coincides with the sliding direction of the abutting plate 5. The linkage bar 35 is slidably connected to the sliding groove 351. Connecting blocks 352 are formed on the side of the abutting plate 5 and the clamping plate 4 facing the pedestal 31. The connecting blocks 352 slide in the sliding groove 351 and are fixed to the linkage bar 35. When the abutting plate 5 moves away from the driving cylinder 34, the linkage bar 35 drives the clamping plates 4 to move in the same direction at the same time.

[0048] See Figure 4 and Figure 5 , an installation groove 43 is formed on the side of the clamping plate 4 away from the pedestal 31. A hinge shaft 6 is rotatably connected between the opposite side walls of the installation groove 43, and the central axis of the hinge shaft 6 is perpendicular to the piston rod of the driving cylinder 34. A fixing plate 7 is fixedly connected to the outer peripheral side of the hinge shaft 6, and the fixing plate 7 can move towards or away from the pedestal 31. Control components 8 are respectively provided on the clamping plates 4 for controlling the direction of the fixing plate 7. The control component 8 includes a control column 83, a control torsion spring 82 and a control rope 81. The control torsion spring 82 is sleeved on the outer peripheral side of the hinge shaft 6. One end of the control torsion spring 82 abuts against the fixing plate 7, and the other end abuts against the groove wall of the installation groove 43. During use, the control torsion spring 82 elastically releases, pushing the fixing plate 7 to flip away from the pedestal 31 until the fixing plate 7 flips to be perpendicular to the pedestal 31.

[0049] See Figure 4 and Figure 5, through holes 831 are respectively formed in the middle positions of the clamping plates 4. The control columns 83 correspond to the through holes 831 one by one and slide in the through holes 831. The control ropes 81 correspond to the control columns 83 one by one and respectively pass through the clamping plates 4. The control ropes 81 adopt an elastic rope structure. One end of the control rope 81 passes through the through hole 831 and is fixed to the hole wall on the side of the through hole 831 away from the fixed plate 7, and the other end of the control rope 81 is fixed to the outer peripheral side of the hinge shaft 6. When the clamping plates 4 slide to respectively abut against the partition plates 2, the control columns 83 slide out of the through holes 831 in the direction of the driving cylinder 34. The control ropes 81 are first abutted against the control columns 83 and then pulled by the control columns 83. At this time, the control ropes 81 pull the hinge shaft 6 to rotate, so that the fixed plate 7 flips towards the direction close to the pedestal 31 until the fixed plate 7 flips to abut tightly against the partition plate 2. At this time, the control torsion spring 82 enters the compressed state, and the partition plate 2 is clamped by the cooperation between the fixed plate 7 and the pedestal 31, further improving the stability of the partition plate 2 while keeping the partition plate 2 in a state of fitting the pedestal 31. When the clamping plates 4 are respectively away from the partition plates 2, the control torsion spring 82 elastically releases, pushing the fixed plate 7 to flip away from the pedestal 31. At this time, the control ropes 81 are wound back to the outer peripheral side of the hinge shaft 6, and the control columns 83 are pushed by the control ropes 81 to move in the direction away from the driving cylinder 34.

[0050] See Figure 5 , in order to prevent the control column 83 from detaching from the through hole 831, a limiting block 84 is fixedly connected to the hole wall of the through hole 831, and a limiting groove 832 is formed on the outer peripheral side of the control column 83. The extending direction of the limiting groove 832 is parallel to the central axis of the through hole 831. During use, the limiting block 84 slides in the limiting groove 832, which is beneficial to reducing the possibility of the control column 83 detaching from the through hole 831.

[0051] See Figure 2 and Figure 3 , the clamping plate 4 is rotatably connected with a rotating shaft 41, and both ends of the rotating shaft 41 protrude to the outside. A rubber column 42 is fixedly connected to the outer peripheral side of the rotating shaft 41. When the rotating shaft 41 rotates, it drives the rubber column 42 to knock on the pedestal 31, causing the pedestal 31 to vibrate. The welding slag adhered to the pedestal 31 slides down along the pedestal 31 under the vibration, reducing the possibility of the welding slag affecting the fitting of the outer plate 1 and the partition plate 2 to the pedestal 31. At the same time, a cavity 311 is formed in the pedestal 31 (the cavity 311 is marked in Figure 4 ), so that the vibration generated when the rubber column 42 knocks can be better transmitted.

[0052] See Figure 2 and Figure 3, a power component 9 is provided on the pedestal 31, and when the clamping plate 4 slides, the power component 9 drives the rotating shaft 41 to rotate. The power component 9 includes a power gear 91 and a power rack 92. The power rack 92 is fixed on the outer peripheral side of the rotating shaft 41. A power groove 93 corresponding to the driving cylinder 34 one by one is formed on one side of the pedestal 31 away from the column 32. The extending direction of the power groove 93 is parallel to the extending direction of the piston rod. The power rack 92 is installed in the power groove 93, and the power rack 92 meshes with the power gear 91. When the clamping plate 4 slides, the power gear 91 drives the rotating shaft 41 to rotate.

[0053] The implementation principle of an electric box body welding device according to an embodiment of the present application is as follows:

[0054] Before welding, first place the outer plate 1 and the partition plate 2 on the pedestal 31, then start the driving cylinders 34 corresponding to the long plates 11 on the upper and lower sides, and then start the driving cylinder 34 corresponding to the short plate 12, so that the abutting plate 5 and the clamping plate 4 abut against the outer plate 1 and the partition plate 2 respectively. At the same time, the fixing plate 7 and the pedestal 31 cooperate to clamp the partition plate 2, realizing the preliminary fixation of the electric box body, and the positions of the outer plate 1 and the partition plate 2 are corrected by the abutting plate 5 and the clamping plate 4, reducing the possibility of deviation. Finally, the welding arm 33 can be started to weld the connection points between the outer plate 1 and the partition plate 2.

[0055] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
