Description

Technical Field

[0001] This invention relates to the field of welding fixture technology, and in particular to a multi-specification copper-nickel integrated welding fixture. Background Technology

[0002] In fields such as power equipment, electronic components, and new energy vehicles, copper-nickel composite structural components are widely used due to their combination of copper's excellent electrical conductivity and nickel's corrosion resistance and high strength. These components typically require precision welding to connect the copper material and nickel sheets into a single unit. Currently, this welding process largely relies on traditional welding fixtures or manual operation.

[0003] In actual production, current welding fixtures usually require frequent changes of special fixtures to adapt to different product models. During the welding process, the nickel sheet needs to be manually placed at the welding point of the battery in advance, and then positioned with handheld or auxiliary tools before welding. This manual positioning process indirectly reduces welding efficiency. In addition, after one side of the battery is welded, the fixture needs to be reset, and then the battery needs to be removed and re-fixed for welding on the other side. The operation steps are quite complicated. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments.

Detailed Implementation

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0038] Example 1, referring to Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a multi-specification copper-nickel integrated welding fixture, which includes a welding component 1 and a fixture component 2. By setting the welding component 1 and the fixture component 2, the force of the welding head pressed down by the existing welding machine body is used as the driving source. During the welding process, synchronous material discharge can be performed, and the nickel sheet 242 can be automatically discharged and automatically positioned above the welding point of the battery. Gradual material discharge welding can be performed. After the welding is completed, welding can continue directly without resetting the workpiece and without the need for an additional power device, thus reducing costs.

[0039] Specifically, welding assembly 1 includes welding machine body 11. The surface of welding machine body 11 is provided with adjustment mechanism 12, and the surface of adjustment mechanism 12 is provided with welding head 13. Adjustment mechanism 12 includes front-back adjustment mechanism, left-right adjustment mechanism and up-down adjustment mechanism. Front-back adjustment mechanism includes hydraulic cylinder, hydraulic pump station and control valve group. Its main function is to provide power source through hydraulic pump station and use hydraulic cylinder to push welding head 13 to move back and forth, thereby driving slider 232 to move back and forth on slide plate 231. The working principle of this part is the prior art and is well known to those skilled in the art, and will not be described in detail here.

[0040] The left and right adjustment mechanism includes a housing, a left and right adjustment motor, a lead screw, a nut mounting plate, and a guide. Its main function is to drive the lead screw to rotate through the left and right adjustment motor, so that the nut mounting plate can drive the welding head 13 to adjust its left and right position, thereby driving the slide plate 231 and the sliding sleeve 233 to move left and right on the crossbar 234. The working principle of this part is existing technology and is well known to those skilled in the art, so it will not be described in detail here.

[0041] The structure of the up-down adjustment mechanism is the same as that of the left-right adjustment mechanism. It is also driven by a lead screw to move the welding head 13 up and down, thereby driving the sliding sleeve 233 to press down the crossbar 234, causing the toothed plate frame 235 to move downward. The working principle of this part is existing technology and is well known to those skilled in the art, so it will not be described in detail here.

[0042] Specifically, the tooling assembly 2 includes a tooling shell 21 disposed on the surface of the welding machine body 11. An actuating component 23 is disposed on the surface of the tooling shell 21. A feeding component 24 is disposed on one side of the top of the tooling shell 21. A positioning component 210 is disposed on the surface of the feeding component 24. A driving component 25 is disposed at the bottom of the tooling shell 21. A transmission component 212 is disposed on the surface of the driving component 25. A clamping component 26 is disposed inside the tooling shell 21. A first push rod 211 is fixed on one side of the inner cavity of the tooling shell 21. Slide rail plates 28 are fixed on both sides of the top of the tooling shell 21.

[0043] Example 2, refer to Figures 2-14 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0044] Specifically, a limiting groove 22 is provided on the surface of the tooling housing 21, and a sliding hole 27 is provided on the surface of the tooling housing 21. The sliding hole 27 is located above the limiting groove 22, and a cover 29 is fixed on both sides of the tooling housing 21.

[0045] Specifically, the actuating component 23 includes a sliding plate 231 disposed below the welding head 13. A slider 232 is slidably connected to the inner cavity of the sliding plate 231. The slider 232 is sleeved on the outer ring of the welding head 13. A sliding sleeve 233 is fixed to the rear side of the sliding plate 231. A crossbar 234 is slidably connected to the inner cavity of the sliding sleeve 233. A toothed plate frame 235 is fixed to both ends of the crossbar 234. A limiting sleeve 236 slides on the surface of the toothed plate frame 235. The limiting sleeve 236 is fixed to the surface of the tooling housing 21.

[0046] Specifically, the drive component 25 includes a reciprocating lead screw 252 movably connected to the bottom of the tooling housing 21. A movable housing 253 is sleeved on the surface of the reciprocating lead screw 252. Connecting frames 251 are fixed on both sides of the movable housing 253. The connecting frames 251 are slidably connected to the inner cavity of the limiting groove 22. An upper slide 2511 is slidably connected to the top of the movable housing 253, and a lower slide 256 is slidably connected to the bottom of the movable housing 253.

[0047] Specifically, a limit rod 254 is fixed to the surface of both the upper slide 2511 and the lower slide 256. The surface of the limit rod 254 is slidably connected to the surface of the movable shell 253. A first spring 255 is sleeved on the surface of the lower slide 256. One end of the first spring 255 is fixed to the surface of the movable shell 253, and the other end of the first spring 255 is fixed to the surface of the lower slide 256. A fixing bracket 257 is fixed between one side of the upper slide 2511 and the lower slide 256.

[0048] Specifically, guide sleeves 259 are fixed on both sides of the movable shell 253. A guide rod 258 is slidably connected to the inner cavity of the guide sleeve 259. A locking block 2514 is fixed to one end of the guide rod 258. A second spring 2510 is sleeved on the outer ring of the guide rod 258. One end of the second spring 2510 is fixed to the surface of the guide rod 258, and the other end of the second spring 2510 is fixed to the surface of the guide sleeve 259. A slot 2513 is opened on the surface of the fixed frame 257. The slot 2513 is located below the locking block 2514. First inclined blocks 2512 are fixed on both sides of the bottom of the upper slide 2511.

[0049] By setting the locking block 2514 and the slot 2513, when the fixed frame 257 moves upward and passes through the slot 2513, the locking block 2514 automatically engages with the slot 2513 under the action of the second spring 2510, thereby supporting the fixed frame 257 and preventing it from falling after rising.

[0050] Specifically, the clamping member 26 includes a clamping plate 261 that slides inside the tooling housing 21. The surface of the clamping plate 261 is threaded with a bolt 262. A second push rod 263 is fixed to the bottom of the clamping plate 261. One end of the bolt 262 extends into the sliding hole 27.

[0051] Specifically, the positioning component 210 includes a fixed shell 2101 fixed to the bottom of the side frame 249. A compression plate 2106 is slidably connected to one side of the fixed shell 2101. A fourth spring 2102 is sleeved on one side of the compression plate 2106. One end of the fourth spring 2102 is fixed to the surface of the compression plate 2106, and the other end of the fourth spring 2102 is fixed to the surface of the fixed shell 2101. A piston plate 2103 is fixed to one side of the compression plate 2106. The piston plate 2103 is slidably connected to the inner cavity of the fixed shell 2101. Connecting pipes 2104 are fixed to both sides of the fixed shell 2101. An airbag column 2105 is fixed to one end of the connecting pipe 2104. The airbag column 2105 is located on one side of the inner cavity of the side frame 249.

[0052] By setting the airbag column 2105, after the extrusion plate 2106 is activated, the gas inside the fixed shell 2101 is compressed, thereby allowing the gas to be discharged into the airbag column 2105, causing the gas to expand, which in turn enables slight clamping of the nickel sheet 242, thereby ensuring that the nickel sheet 242 is positioned before welding, facilitating subsequent welding work.

[0053] Example 3, referring to Figures 4-15 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0054] Specifically, the unloading component 24 includes a material frame 241 fixed to one end of the connecting frame 251, a nickel sheet 242 slidably connected to the inner cavity of the slide rail plate 28, a counterweight 243 slidably connected to the top of the inner cavity of the material frame 241, a pusher plate 244 slidably connected to the bottom of the material frame 241, inclined holes 245 are provided at both ends of the pusher plate 244, rolling columns 248 are slidably connected to the inside of the inclined holes 245 and the top of the slide rail plate 28, a connecting column 247 is fixed between the rolling columns 248, the connecting column 247 is rotatably connected to the bottom of the material frame 241, a pressing rod 246 is fixed at both ends of the pusher plate 244, a side frame 249 is fixed to the bottom of one side of the material frame 241, grooves 2410 are provided on both sides of the inner cavity of the side frame 249, a third spring 2411 is fixed in the inner cavity of the groove 2410, and a second inclined block 2412 is fixed to one end of the third spring 2411.

[0055] By setting up a reciprocating screw 252, an upper slide 2511, and a lower slide 256, the pusher plate 244 can be driven to push the nickel sheet 242 simultaneously during the movement of the material frame 241, thereby enabling the nickel sheet 242 to be automatically pushed into the side frame 249 for positioning during the movement.

[0056] By setting the slide rail plate 28, the movement of the connecting column 247 can be guided, so that the connecting column 247 can move inside the inclined hole 245 through the rolling column 248 and drive the pusher plate 244 to move.

[0057] By setting the extrusion rod 246, it can move synchronously during the movement of the pusher plate 244, thereby driving the extrusion plate 2106 to move synchronously and ensuring that the airbag column 2105 is inflated synchronously.

[0058] Specifically, the transmission component 212 includes a gear 2121 movably connected to both ends of the reciprocating lead screw 252. Both ends of the reciprocating lead screw 252 are fixed with ratchet 2122. A pawl 2123 is rotatably connected to one side of the gear 2121. A torsion spring 2124 is fixed to one side of the ratchet 2122. One end of the torsion spring 2124 is fixed to one side of the ratchet 2122. The pawl 2123 engages with the ratchet teeth of the ratchet 2122.

[0059] By setting the torsion spring 2124, the pawl 2123 can be stably locked on the surface of the ratchet 2122, and the pawl 2123 can be automatically reset after the ratchet 2122 pushes the pawl 2123 away.

[0060] By setting the limit sleeve 236, the movement of the gear plate frame 235 can be guided, so that it can run stably during the movement and avoid shaking, which would cause insufficient meshing or slippage between it and the gear 2121.

[0061] By setting ratchet 2122 and pawl 2123, gear 2121 can drive reciprocating screw 252 to rotate only when it rotates in one direction. When welding head 13 rises, pawl 2123 loses its lock on ratchet 2122, allowing gear 2121 to rotate freely on reciprocating screw 252, thus not driving reciprocating screw 252 to rotate. This ensures that the feeding action continues in one direction and ensures the accuracy of feeding positioning.

[0062] By setting the toothed plate frame 235 and the gear 2121, the linear motion of the welding head 13 pressing down can be converted into rotational motion, and the reciprocating screw 252 will only rotate during the welding pressing down, and will not rotate during the rising process, thus effectively ensuring that the reciprocating screw 252 only moves during the pressing down process.

[0063] By providing the cover 29, the transmission component 212 and the gear plate frame 235 can be protected to prevent external impurities from entering during operation. At the same time, the above-mentioned components can be hidden to improve the aesthetics of the device.

[0064] Specifically, the airbag column 2105 and the second inclined block 2412 are arranged in a rectangular pattern. This arrangement can simultaneously limit the four corners of the nickel sheet 242, thereby achieving the effect of positioning the nickel sheet 242.

[0065] Specifically, notches are provided on both sides of the pusher plate 244. By setting the notches, it can be ensured that the pusher plate 244 will not come into contact with the second inclined block 2412 during the movement, so as not to squeeze the second inclined block 2412.

[0066] Specifically, the bottom of the tool housing 21 has a cavity, and the second push rod 263 is located inside the cavity. By setting the cavity, space can be provided for the movement of the second push rod 263 so that it will not be obstructed during its movement, thereby ensuring subsequent contact with the first inclined block 2512.

[0067] In use, the slider 232 is connected to the welding head 13, and the nickel sheets 242 are stacked one by one inside the material frame 241. Then, the counterweight 243 is placed on top of the nickel sheets 242 and a slight pressure is applied to them so that they can fall automatically. The tooling housing 21 is limited to a fixed width, which can just accommodate four standard batteries. Its length is adjustable, and the specifications of individual batteries are the same, while the length specifications of the battery packs they form are different.

[0068] Place the battery inside the fixture housing 21, close to one side of the fixture housing 21, then move the clamp 261 so that the clamp 261 is close to the battery pack, and then tighten the bolt 262 so that the bolt 262 is tightly attached to the fixture housing 21 to fix the clamp 261, thereby achieving the effect of clamping and fixing the battery pack.

[0069] When the adjusting mechanism 12 drives the welding head 13 to adjust back and forth, the slider 232 moves back and forth inside the slide plate 231. When the welding head 13 adjusts left and right, the sliding sleeve 233 slides left and right on the surface of the crossbar 234. When the welding head 13 presses down to weld, the slider 232 drives the slide plate 231 and the sliding sleeve 233 to move down, thereby driving the toothed plate frame 235 to move down, so that the teeth on the surface of the toothed plate frame 235 mesh with the gear 2121. At this time, the gear 2121 rotates, driving the pawl 2123 to rotate. The pawl 2123 presses against the ratchet 2122, thereby driving the reciprocating screw 252 to rotate.

[0070] At this time, the locking block 2514 is located above the locking groove 2513. Under the elastic force of the first spring 255, the upper slide 2511 is located inside the circulation groove of the reciprocating screw 252, while the lower slide 256 is located outside the circulation groove of the reciprocating screw 252. When the reciprocating screw 252 rotates, the upper slide 2511 moves to the right inside the circulation groove of the reciprocating screw 252, thereby driving the moving shell 253 to move, and driving the material frame 241 to move synchronously through the connecting frame 251.

[0071] During the movement of the material frame 241, the connecting column 247 moves synchronously. The rolling column 248 at one end of the connecting column 247 moves guided inside the slide rail at the top of the slide rail plate 28. At this time, the rolling column 248 at the other end of the connecting column 247 moves through the inclined hole 245 on the surface of the pusher plate 244, thereby causing the pusher plate 244 to move into the material frame 241 during the synchronous movement with the material frame 241. At this time, the pusher plate 244 pushes the nickel sheet 242 from inside the material frame 241 towards the side frame 249. The nickel sheet 242 presses the second inclined block 2412, causing the third spring 2411 to compress.

[0072] When the nickel sheet 242 has completely passed the second inclined block 2412, the third spring 2411 loses pressure and rebounds to its original position, thereby driving the second inclined block 2412 to return to its original position and make it contact one side of the nickel sheet 242. At this time, the pusher plate 244 drives the extrusion rod 246 to move to contact the extrusion plate 2106 and extrude. The fourth spring 2102 is compressed, and the extrusion plate 2106 pushes the piston plate 2103 to move, which compresses the gas inside the fixed shell 2101 and enters the airbag column 2105 through the connecting pipe 2104, causing the airbag column 2105 to expand. Thus, together with the second inclined block 2412, the nickel sheet 242 is slightly clamped and positioned. At this time, the rolling column 248 moves to the first turning point inside the slide rail at the top of the slide rail plate 28.

[0073] When the welding head 13 contacts the nickel sheet 242 and pushes it downwards above the solder joint of the battery pack, the nickel sheet 242 is positioned between the airbag column 2105 and the second inclined block 2412, close to the solder joint of the battery pack, so it will not deviate when falling. At this time, the welding head 13 welds the nickel sheet 242 to the first solder joint of the battery pack from back to front. When the welding head 13 moves upwards, the toothed frame 235 moves upwards, and at this time the gear 2121 rotates in the opposite direction.

[0074] The pawl 2123 rotates in the opposite direction on the surface of the ratchet 2122 and does not press against the surface of the ratchet 2122. Therefore, it will not drive the ratchet 2122 to rotate. So, during the upward movement of the welding head 13, the reciprocating screw 252 will not rotate. When the welding head 13 makes the second and third welding points from back to front, the rolling column 248 moves on the first straight section of the slide rail on the slide rail plate 28. At this time, the connecting column 247 will not move back and forth. Therefore, the pusher plate 244 will not move.

[0075] When the welding head 13 is making the fourth welding point from back to front, the rolling column 248 moves to the second turning point inside the slide rail at the top of the slide rail plate 28. At this time, the movement direction of the rolling column 248 is opposite to the movement direction before the first turning point, thus driving the pusher plate 244 to move in the opposite direction. When the rolling column 248 moves to the third turning point inside the slide rail at the top of the slide rail plate 28, the pusher plate 244 is completely reset. At this time, the first nickel sheet 242 is welded. When the welding head 13 moves to the second welding point area, the above steps are repeated to perform welding.

[0076] After all the welding points of the battery pack are completed, the battery pack is taken out, flipped over and put back in. The welding head 13 continues to move down, and the moving shell 253 moves to the second push rod 263 at the bottom of the clamping plate 261 and contacts it. At this time, the second push rod 263 presses against the first inclined block 2512. Under the action of the inclined surface, the upper slide 2511 moves upward. During the upward movement of the upper slide 2511, the fixed frame 257 is driven to move upward until the slot 2513 on the fixed frame 257 moves to the slot 2514.

[0077] At this time, under the elastic action of the second spring 2510, the locking block 2514 is driven into the slot 2513, causing the upper slide 2511 to disengage from the circulation groove of the reciprocating screw 252, and the lower slide 256 moves into the circulation groove of the reciprocating screw 252. When the reciprocating screw 252 continues to rotate, the lower slide 256 will move in the opposite direction along the circulation groove of the reciprocating screw 252, thus allowing welding to continue in the opposite direction. When the guide rod 258 contacts the first push rod 211, the guide rod 258 is squeezed, thereby causing the locking block 2514 to move out of the slot 2513. At this time, under the elastic force of the first spring 255, the fixing frame 257 is driven to descend, thereby causing the upper slide 2511 to move back into the circulation groove of the reciprocating screw 252, and the lower slide 256 moves out of the circulation groove of the reciprocating screw 252.
