Description

Technical Field

[0001] The present invention relates to the technical field of battery housing processing, and particularly to a processing device for a new energy vehicle battery housing. Background Art

[0002] The battery housing is an external container that protects the internal components of the battery, and it is crucial for ensuring the safety, stability, and service life of the battery. The battery housing is usually box-shaped and assembled and welded by a U-shaped part and an L-shaped part. Both the U-shaped part and the L-shaped part are formed by bending sheet metal. Currently, there are still the following problems when welding the two parts of the welded workpiece: The splicing accuracy between the U-shaped welded workpiece and the L-shaped welded workpiece will directly affect the inner diameter dimension accuracy of the battery housing. Currently, welders only perform assembly through a welding platform and fixtures, and the welder manually controls the welding platform and fixtures to fix and combine the U-shaped welded workpiece and the L-shaped welded workpiece, resulting in low assembly efficiency; Secondly, during the splicing process of the L-shaped welded workpiece and the U-shaped welded workpiece, the positioning of the two side edges of the L-shaped welded workpiece will hinder the vertical seam, making it difficult for the welding equipment to continuously complete the welding of the overall seam, and the welding efficiency is low; Furthermore, during the process of moving the two parallel segments of the U-shaped welded workpiece and the horizontal segment of the L-shaped welded workpiece onto the welding platform, or during the manual splicing process, it is relatively easy to generate an inward bending situation, but there is no straightening mechanism that can be implemented on the welding platform, and the inward bending situation will cause the对接 ends of the U-shaped welded workpiece and the L-shaped welded workpiece to be difficult to fully contact, directly reducing the quality of the welded battery housing formed.

[0036] See also Figure 1 , Figure 2 , Figure 3The outer clamping assembly 21 includes an outer center plate 211 slidably mounted on the top of the processing table 1, and the front and rear ends of the outer center plate 211 are slidably mounted with outer clamping plates 212 perpendicular to the outer center plate 211. A pushing component 213 is installed on the top of the processing table 1 to drive the outer center plate 211 to move left and right. A guiding component 214 is installed on the processing table 1 to guide the outer clamping plate 212 to be clamped inward by the right movement of the outer center plate 211. The pushing component 213 includes a pushing plate 2131 slidably mounted on the top of the processing table 1, and the left side of the outer center plate 211 is fixed. It is fixedly connected with a guide rod 2132 which is symmetrically distributed frontward and rearward. The left end of the guide rod 2132 slides through the left side of the pushing plate 2131 and is fixedly connected with a stopper. A compression spring 2133 which is sleeved on the outside of the guide rod 2132 is fixedly connected between the pushing plate 2131 and the outer center plate 211. The guiding component 214 includes a guiding inclined groove 2141 which is symmetrically opened frontward and rearward on the top of the processing table 1 and the right end is inclined toward the center direction of the processing table 1. The bottom of the outer clamping plate 212 is fixedly connected with a slider 2142, and the slider 2142 is slidably installed inside the corresponding guiding inclined groove 2141.

[0037] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The inner correction component 22 includes an inner center plate 221 fixedly connected to the top of the processing table 1 and located on the right side of the outer center plate 211. The front and rear ends of the inner center plate 221 are rotatably connected to the inner splint 222 located on the inner side of the outer splint 212 through an axle rod. A rotating component 223 for driving the corresponding inner splint 222 to rotate is installed at the bottom of the inner center plate 221. An angle limiting component 224 corresponding to the inner splint 222 and limiting the rotation angle of the inner splint 222 is installed on the right side of the inner center plate 221.

[0038] See also Figure 1 , Figure 2 , Figure 3 and Figure 4When the C-shaped welded part needs to be fixed and corrected, the C-shaped welded part is placed with its opening facing the right side, and the horizontal longitudinal section of the C-shaped welded part is placed between the outer center plate 211 and the inner center plate 221. The two parallel sections of the C-shaped welded part are respectively located between the corresponding outer clamping plate 212 and the inner clamping plate 222. Then, the pushing plate 2131 is driven to move to the right by the moving mechanism 4. The pushing plate 2131 pushes the outer center plate 211 to move to the right by compressing the compression spring 2133. In the process of the outer center plate 211 moving to the right, the guiding inclined groove 2141 guides the slider 2142, so that the slider 2142 drives the outer clamping plate 212 to move toward the center of the processing table 1. When the outer center plate 211 is pressed against the left side of the horizontal longitudinal section of the C-shaped welded part, the outer clamping plate 212 is just pressed against the outer side of the corresponding parallel section of the C-shaped welded part.

[0039] At the same time, when the above-mentioned outer center plate 211 moves to the right, the outer center plate 211 will drive the rack 2231 to move to the right, and the rack 2231 will mesh with the inner side of the gear 2232. The rack 2231 is used to drive the corresponding gear 2232 to rotate, and then the gear 2232 drives the inner clamping plate 222 to deflect outward, so that the inner clamping plate 222 straightens the two parallel sections of the U-shaped welded part from the inside to the outside. When the inner clamping plate 222 rotates to be perpendicular to the inner center plate 221, the outer clamping plate 212 is just pressed against the outer side of the U-shaped welded part, thereby correcting the two parallel sections of the U-shaped welded part to be perpendicular to the horizontal section, which is convenient for subsequent assembly and welding.

[0040] See also Figure 1 , Figure 2 , Figure 6 and Figure 7 The outer clamping assembly 2 31 includes a movable seat 311 slidably mounted on the top of the processing table 1, an inverted L-shaped outer support frame 312 is fixedly mounted on the top of the movable seat 311, a limit plate 313 is slidably mounted on the top of the outer support frame 312, a left-right moving component 314 driving the limit plate 313 to move left-right is installed on the horizontal section of the outer support frame 312, and the left-right moving component 314 includes a slide groove 3141 opened on the top of the horizontal section of the outer support frame 312, and the slide groove 3141 is fixedly mounted on the top of the outer support frame 312. A threaded rod 3142 is rotatably installed inside 3141, and a slide seat 3143 is threadedly connected to the outside of the threaded rod 3142. The slide seat 3143 is slidably installed inside the slide groove 3141, and a limit plate 313 is fixedly installed on the top of the slide seat 3143. The right end of the threaded rod 3142 rotates and passes through the right side of the outer support frame 312 and is fixedly connected to a turning handle 3144. The turning handle 3144 is threadedly connected to a limit pin 3145 that is plugged into the outer support frame 312.

[0041] In the initial state, the first limiting plate 313 is located at the left end of the horizontal section of the outer support frame 312. The first limiting plate 313 functions to resist and limit the horizontal section of the L-shaped welded part. After the L-shaped welded part and the U-shaped welded part are welded, the limit pin 3145 is loosened to release the limit on the rotary handle 3144, and then the rotary handle 3144 is rotated to drive the threaded rod 3142 to rotate. By using the threaded rod 3142, the first sliding seat 3143 is driven to move to the right. The first sliding seat 3143 drives the first limiting plate 313 to move to the right, so that the first limiting plate 313 no longer blocks the top of the battery housing, facilitating the upward removal of the welded battery housing.

A top push component 324 is installed at the left end of the top push plate 322. It should be noted that rollers are rotatably installed on the sides of the inner center plate 221, the inner clamping plates 222, and the vertical section of the inner support frame 321 that are in contact with the corresponding U-shaped welded part and L-shaped welded part to reduce the friction with the U-shaped welded part and L-shaped welded part, facilitating the upward removal of the welded battery housing.

[0043] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 , when fixing and correcting the L-shaped welded part, place the vertical section of the L-shaped welded part between the vertical sections of the inner support frame 321 and the outer support frame 312, and place the horizontal section of the L-shaped welded part between the top push plate 322 and the first limiting plate 313. Use the moving mechanism 4 to drive the movable seat 311 to move to the left. The movable seat 311 drives the outer support frame 312 and the first limiting plate 313 to move to the left together. At this time, the inner support frame 321 remains stationary under the support of the second elastic telescopic rod 34, and the vertical sections of the inner support frame 321 and the outer support frame 312 are used to clamp and fix the vertical section of the L-shaped welded part.

Limiting blocks 3234 which slide in cooperation with the corresponding arc-shaped limiting groove 3233 are fixedly connected to the front and rear sides of the movable plate 3232. The angle limiting component 1 224 has the same structure as the angle limiting component 323.

[0045] When the push plate 322 deflects upward, the push plate 322 will drive the movable plate 2 3232 to rotate upward together. At this time, the movable plate 2 3232 will drive the limit block 3234 to slide upward along the arc-shaped limit groove 3233. When the push plate 322 rotates to a horizontal state, the limit block 3234 just slides to the upper end of the arc-shaped limit groove 3233. The arc-shaped limit groove 3233 is used to limit the rotation angle of the limit block 3234, the movable plate 2 3232 and the push plate 322 to avoid excessive rotation of the push plate 322, and ensure that the push plate 322 just corrects the horizontal section of the L-shaped welded part to a state perpendicular to its vertical section.

[0046] See also Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 The pushing component 324 includes a front-to-back symmetrical groove opened at the bottom of the left end of the pushing plate 322, and a rotating shaft 3241 fixedly connected in the groove, and rollers 3242 symmetrically distributed front-to-back are rotatably installed on the rotating shaft 3241, and a positioning block 3243 is fixedly connected to the middle of the rotating shaft 3241, and the bottom end of the positioning block 3243 extends to the bottom of the pushing plate 322, and an inclined plate 3244 is fixedly connected to the right side of the inner clamping plate 222, and the left side of the top of the inclined plate 3244 is flush with the top of the inner clamping plate 222 and the right side is inclined downward, and the top of the inclined plate 3244 and the inner clamping plate 222 are jointly provided with a positioning groove 3245 that slidably cooperates with the positioning block 3243, and the inner support frame 321 is provided with a through groove corresponding to the inclined plate 3244.

[0047] After the outer support frame 312 and the inner support frame 321 clamp and fix the vertical section of the L-shaped welded part, the moving mechanism 4 continues to drive the movable seat 311 to move left, and the outer support frame 312 will push the L-shaped welded part and the inner support frame 321 to move left together. At this time, the elastic telescopic rod 234 will be compressed, and the inner clamping plate 222 has been rotated to a state parallel to the inner center plate 221, that is, the correction of the L-shaped welded part is completed, and the outer clamping plate 212 and the inner clamping plate 222 are clamped on the inner and outer sides of the L-shaped welded part respectively. When the inner support frame 321 is close to the inner clamping plate 222, the roller 3242 and the top of the inclined plate 3244 The push plate 322 is supported and guided by the inclined plate 3244, so that the push plate 322 is rotated upward to a horizontal state. When the push plate 322 is horizontal and continues to slide, the roller 3242 can roll along the top of the inner clamping plate 222, thereby reducing the friction between the push plate 322 and the inner clamping plate 222. At the same time, the positioning block 3243 will move along the positioning groove 3245, and the positioning groove 3245 will be used to guide and limit the positioning block 3243, thereby ensuring that the push plate 322 and the inner clamping plate 222 are accurately spliced ​​together, thereby improving the accuracy of the splicing of the L-shaped welded parts and the U-shaped welded parts.

[0048] When the push plate 322 moves to the top of the inner clamp plate 222, the horizontal section of the inner support frame 321 moves between the front and rear inner clamp plates 222. At this time, the guide block 3211 is inserted into the inside of the guide groove 2221 and slides to the left along the guide groove 2221. The horizontal section of the inner support frame 321 is used to limit the front and rear inner clamp plates 222 to prevent the inner clamp plates 222 from rotating inward, thereby improving the firmness of the inner clamp plates 222 to expand the two parallel sections of the U-shaped welded parts.

[0049] See also Figure 1 , Figure 2 , Figure 6 , Fig.11 and Fig.12 The front and rear alignment components 33 include a baffle plate 331 fixedly connected to the top of the processing table 1 and symmetrically distributed about the movable seat 311. The left and right ends of the baffle plate 331 are penetrated and slidably installed with a movable rod 332 in the front and rear. A return spring 333 sleeved on the outside of the movable rod 332 is fixedly connected between the end of the movable rod 332 away from the movable seat 311 and the baffle plate 331. After the left and right movable rods 332 penetrate into the inner side of the movable seat 311, they are jointly fixedly connected to an alignment plate 334. The bottom of the alignment plate 334 is provided with a guide groove 335 for guiding the alignment plate 334 to move toward the movable seat 311. The guide groove 335 is composed of horizontal sections arranged alternately in the front and rear and inclined sections connected between the horizontal sections. The top of the movable seat 311 is fixedly connected with an elastic telescopic rod 336 that slidably cooperates with the guide groove 335, and the top of the telescopic section of the elastic telescopic rod 336 is provided with an inclined surface inclined to the lower right side.

[0050] When the movable seat 311 drives the outer support frame 312 to move leftward to clamp the vertical section of the L-shaped welded part, the movable seat 311 will drive the first elastic telescopic rod 336 to move leftward. Before the vertical sections of the outer support frame 312 and the inner support frame 321 clamp the vertical section of the L-shaped welded part, the first elastic telescopic rod 336 will first enter the guiding groove 335 and move leftward along the guiding groove 335. By using the cooperation of the first elastic telescopic rod 336 and the guiding groove 335, the alignment plate 334 and the movable rod 332 are driven to move towards the center of the processing table 1. At this time, the third reset spring 333 will be compressed, and the alignment plate 334 is used to synchronously center and clamp the front and rear sides of the L-shaped welded part to ensure that the front and rear sides of the L-shaped welded part are aligned with those of the U-shaped welded part. After the front and rear centering of the L-shaped welded part, the vertical sections of the outer support frame 312 and the inner support frame 321 clamp the vertical section of the L-shaped welded part again.

[0051] After the vertical sections of the outer support frame 312 and the inner support frame 321 clamp the vertical section of the L-shaped welded part again, as the movable seat 311 moves leftward, the first elastic telescopic rod 336 moves out from the left end of the guiding groove 335. At this time, the resilience of the third reset spring 333 is used to push the alignment plate 334 to move and reset in the direction away from the center of the processing table 1, and the alignment plate 334 is separated from the L-shaped welded part and no longer clamps the front and rear sides of the L-shaped welded part, avoiding blocking the subsequent welding of the L-shaped welded part and the U-shaped welded part.

[0052] When the movable seat 311 drives the first elastic telescopic rod 336 to move rightward to reset, the inclined surface on the telescopic section of the first elastic telescopic rod 336 will contact the bottom of the alignment plate 334, and then under the pushing of the alignment plate 334, the telescopic section of the first elastic telescopic rod 336 contracts downward, so that the first elastic telescopic rod 336 moves from below the alignment plate 334 to the right side of the alignment plate 334.

[0053] Please refer to Figure 1 、 Figure 2 、 Figure 6 and Fig.13 As shown in

[0054] The moving mechanism 4 includes second chutes 41 which are symmetrically arranged left and right on the top of the processing table 1. A bidirectional lead screw 42 is rotatably connected inside the left and right second chutes 41. Both the left and right ends of the bidirectional lead screw 42 are threadedly connected with second sliding seats 43. The second sliding seats 43 are slidably installed left and right in the corresponding second chutes 41. A driving motor 44 is fixedly installed on the left side of the processing table 1. The right end of the output shaft of the driving motor 44 is coaxially and fixedly connected with the left end of the bidirectional lead screw 42. The left second sliding seat 43 is fixedly installed at the bottom of the pushing plate 2131, and the right second sliding seat 43 is fixedly installed at the bottom of the movable seat 311.The bidirectional lead screw 42 is driven to rotate by the driving motor 44, so that the slide seats 43 at the left and right ends move toward each other, the slide seat 43 on the left side drives the pushing plate 2131 to move right, and the slide seat 43 on the right side drives the movable seat 311 to move left. When the outer center plate 211, the outer clamping plate 212, and the inner clamping plate 222 complete the external clamping and straightening of the L-shaped welded component, the vertical sections of the inner support frame 321 and the outer support frame 312 synchronously complete the clamping of the vertical section of the L-shaped welded component, and then the slide seats 43 on the left and right sides continue to drive the pushing plate 2131 and the movable seat 311 to move toward each other. At this time, the compression spring 2133 and the elastic telescopic rod 234 will be compressed until the L-shaped welded component and the L-shaped welded component are spliced ​​together. At this time, the left end of the horizontal section of the inner support frame 321 conflicts with the right end of the inner center plate 221.

[0055] See also Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The positioning assembly 1 23 includes a plurality of hollow shells 231 fixedly mounted on the processing table 1 and matched in pairs. The inner center plate 221 is located between the corresponding and matched hollow shells 231. A pair of matched hollow shells 231 is arranged between the outer clamping plate 212 and the corresponding inner clamping plate 222. A wedge block 232 is slidably mounted on the top of the hollow shell 231. The bottom of the wedge block 232 penetrates into the interior of the hollow shell 231 and is fixedly connected with a baffle 233. The baffle 233 is slidably mounted on the interior of the hollow shell 231. A return spring 1 234 is fixedly connected between the bottom of the baffle 233 and the inner wall of the hollow shell 231. The positioning component 24 has the same structure as the positioning component 1 23. The hollow shell 231 in the positioning component 24 is fixedly installed on the top of the right side of the inner center plate 221. The bottom of the outer center plate 211, the outer clamping plate 212, the inner clamping plate 222 and the inner support frame 321 are all provided with a card groove 1 that matches the corresponding wedge block 232. The bottom of the push plate 322 is provided with a card groove 2 that matches the wedge block 232 in the positioning component 24.

[0056] When the outer center plate 211 presses the U-shaped welded part tightly against the left side of the inner center plate 221, the outer center plate 211 moves above the positioning component 23 on the left side of the inner center plate 221. The resilience of the first return spring 234 is used to push the retaining piece 233 and the wedge-shaped block 232 upward, so that the wedge-shaped block 232 is clamped into the corresponding first card slot at the bottom of the outer center plate 211, realizing the locking of the outer center plate 211, preventing the outer center plate 211 from becoming loose, improving the firmness between the outer center plate 211 and the inner center plate 221. Similarly, when the outer clamping plate 212 and the inner clamping plate 222 clamp the inner and outer sides of the two parallel sections of the U-shaped welded part, the outer clamping plate 212 and the inner clamping plate 222 move onto the positioning component 23 located between them. The positioning component 23 is used to lock the outer clamping plate 212 and the inner clamping plate 222 on the inner and outer sides of the U-shaped welded part, improving the firmness of the outer center plate 211 and the inner clamping plate 222 in clamping and fixing the two horizontal sections of the U-shaped welded part.

[0057] When the L-shaped welded part and the U-shaped welded part are joined together, the left end of the horizontal section of the inner support frame 321 abuts against the right end of the inner center plate 221. The left end of the top push plate 322 presses against the positioning component 24 and is locked by the positioning component 24. At this time, the positioning component 23 on the right side of the inner center plate 221 locks the left end of the inner support frame 321, preventing the inner support frame 321 from separating from the inner center plate 221. The wedge-shaped block 232 in the positioning component 24 is clamped into the corresponding second card slot at the bottom of the top push plate 322, locking the top push plate 322 to prevent the top push plate 322 from separating from the inner center plate 221, improving the tightness of the connection between the inner support frame 321, the top push plate 322 and the inner center plate 221, and further improving the tightness of the joining of the U-shaped welded part and the L-shaped welded part.

[0058] Please refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 , the unlocking component 25 includes a movable plate 251 slidably installed up and down inside the processing table 1. A second return spring 252 is fixedly connected between the bottom of the movable plate 251 and the inner wall of the processing table 1. The bottom of the movable plate 251 is fixedly connected with a pull rod 253 located below the processing table 1 through a short rod. The short rod movably penetrates the processing table 1. The top of the movable plate 251 is fixedly connected with a number of linkage rods 254 corresponding one by one to the paired hollow shells 231 in the positioning component 23. The inner center plate 221 and the processing table 1 are respectively slidably connected with the corresponding linkage rods 254. Side rods 255 are fixedly connected to the lower ends of the linkage rods 254 corresponding to the positions of the hollow shells 231. Side rods 255 are also fixedly connected to the upper ends of the linkage rods 254 on the inner center plate 221 corresponding to the hollow shells 231 in the positioning component 24. The side rods 255 are slidably connected with the corresponding hollow shells 231 up and down and press against the upper ends of the corresponding retaining pieces 233.

[0059] After the welding of the U-shaped and L-shaped welded parts is completed, when the lock of the positioning component 23 is to be released, the pull rod 253 is pushed downward, and the pull rod 253 is used to drive the movable plate 251 to move downward, and the movable plate 251 drives the linkage rod 254 and the side rod 255 to move downward. At this time, the return spring 252 will be compressed, and the side rod 255 is used to push the baffle 233 downward, so that the wedge block 232 is retracted into the hollow shell 231, and the wedge block 232 is released from the lock of the outer center plate 211, the outer clamping plate 212, the inner clamping plate 222 and the inner support frame 321. Similarly, when the linkage rod 254 and the side rod 255 move downward, the side rod 255 corresponding to the positioning component 24 releases the lock of the positioning component 24 on the push plate 322.

[0060] See also Figure 1 , Figure 2 , Figure 3 , Figure 6 , Fig. 9 and Fig.10 The interlocking mechanism 5 includes an insertion rod assembly 51 and a locking column 52. The insertion rod assembly 51 includes a mounting seat 511 with a U-shaped structure, and a plug rod 512 rotatably connected to the mounting seat 511 through a rotating rod. The opening of the mounting seat 511 faces the locking column 52. A torsion spring 513 is connected between the rotating rod and the plug rod 512. A partition plate 1 for limiting the rotation angle of the plug rod 512 is fixedly connected between the two parallel sections of the mounting seat 511. The right end of the outer clamping plate 212 and the left end of the limiting plate 1313 are both fixedly installed with the mounting seat 511. Among them, the outer clamping plate 21 corresponding to the front is fixedly connected to the outer clamping plate 211. 2, the partition restricts the corresponding plug-in rod 512 from rotating downward, the partition corresponding to the outer clamping plate 212 at the rear restricts the corresponding plug-in rod 512 from rotating upward, and the partition corresponding to the limit plate 313 restricts the corresponding plug-in rod 512 from rotating forward. A retaining groove matching the corresponding plug-in rod 512 is provided on the lock column 52, and 52 lock columns corresponding to the mounting seats 511 are fixedly installed on the front and rear sides of the outer support frame 312 and the top of the outer center plate 211. The number of mounting seats 511 on the right end of the outer clamping plate 212 and the left end of the limit plate 313 is at least two.

[0061] See also Figure 1 , Figure 2 , Figure 3 , Figure 6 , Fig. 9 and Fig.10When the U-shaped welded component and the L-shaped welded component are assembled together, the outer clamping plate 212 and the limiting plate 313 drive the corresponding plug-in rod 512 to be inserted into the corresponding retaining groove, and the retaining groove is used to block and limit the plug-in rod 512. Through the cooperation of the outer clamping plate 212, the inner clamping plate 222 with the corresponding plug-in rod 512 and the retaining groove, and through the cooperation of the limiting plate 313, the push plate 322 with the corresponding plug-in rod 512 and the retaining groove, the splicing seam between the U-shaped welded component and the L-shaped welded component is limited front and rear.

[0062] During the welding process, the welding head of the multi-dimensional welding machine 6 moves from front to back along the joint seam between the U-shaped tailored welded part and the L-shaped tailored welded part, and the welding head first moves from bottom to top, then from front to back, and then from top to bottom. Taking the movement of the welding head from bottom to top as an example, when the welding head moves to the plug rod 512, the non-working section of the welding head is used to push the plug rod 512 to rotate upward (see the attached diagram). Fig. 9 ), the end of the plug rod 512 is separated from the corresponding retaining groove to prevent the plug rod 512 from blocking the movement of the welding head. At the same time, since no less than two plug rod assemblies 51 are installed on each outer clamping plate 212 and the limiting plate 313, when one plug rod assembly 51 is unlocked, the other plug rod assembly 51 remains connected, ensuring that the joint seam between the U-shaped welded component and the L-shaped welded component is limited front and rear.

[0063] When the welding head moves to the other side of the plug-in rod 512, the push of the welding head is lost, and the resilience of the torsion spring 513 is used to push the plug-in rod 512 to rotate. The plug-in rod 512 rotates to a horizontal state under the limit of the corresponding partition, and the plug-in rod 512 is re-inserted into the retaining groove for limit.

[0064] See also Figure 1-Figure 13After the welding is completed, the multi-dimensional welding machine 6 is moved away from the top of the battery shell, and then the left and right moving component 314 drives the limit plate 1 313 to move to the right, exposing the top of the battery shell, and then the battery shell is taken out upward, and then the pull rod 253 is pressed downward to release the lock of the positioning component 1 23, and then the driving motor 44 drives the bidirectional lead screw 42 to rotate in the opposite direction, so that the left and right slide seats 2 43 move back to back, and then the slide seat 2 43 drives the pushing plate 2131 and the movable seat 311 to move back to back, and the movable seat 311 will first drive the outer support frame 312 and the inner support frame 321 to move right and connect with the outer clamping plate 212 and the inner clamping plate 213. The side clamping plates 222 separate, and when the pushing plate 322 separates from the inner clamping plates 222, the pushing plate 322 deflects towards each other under the action of its own gravity, and then the movable seat 311 continues to move to the right. When the elastic telescopic rod 234 returns to its original length, the inner support frame 321 no longer moves to the right. At this time, the movable seat 311 drives the outer support frame 312 to move to the right, and relative sliding occurs between the inner support frame 321 and the movable seat 311, so that the distance between the outer support frame 312 and the inner support frame 321 is enlarged, which is convenient for the placement of subsequent L-shaped welded parts, until the right side slide seat 243 moves to the right end of the right side slide groove 241 and stops moving.

[0065] When the inner support frame 321 is completely moved to the right side of the inner clamping plate 222, the pushing plate 2131 drives the compression spring 2133 to return to its original length. Thereafter, the pushing plate 2131 continues to move to the left and drives the outer center plate 211 to move to the left through the compression spring 2133. During the movement of the outer center plate 211 to the left, the guide inclined groove 2141 guides the slider 2142 and the outer clamping plate 212 to move away from the center of the processing table 1, thereby expanding the distance between the outer clamping plate 212 and the inner center plate 221, and facilitating the placement of subsequent U-shaped welded parts. When the outer center plate 211 is away from the inner center plate 221, the outer center plate 211 drives the rack 2231 to move to the left, and then the rack 2231 drives the gear 2232 to rotate in the opposite direction, so that the inner clamping plate 222 is deflected and reset in the direction close to the center of the processing table 1, until the left slide seat 243 moves to the left end of the left slide groove 241 and stops moving.
