[0002] The welding of new energy storage battery boxes usually refers to connecting metal plates (such as aluminum alloy plates) through welding processes to form the structure of the battery box. After pre-processing such as cutting and bending, these metal plates are connected into various parts of the battery box, such as the bottom plate, side plate, end cover, etc. through welding processes. The technologies that may be used in the welding process include laser welding, resistance spot welding, cold metal transition welding, high-frequency wire drawing welding, stir friction welding, etc. In the welding process, in order to ensure the welding effect, special welding fixtures are usually required;

[0003] The existing welding fixture for new energy storage battery box is often used in the welding of new energy storage battery box. For example, a welding fixture (application number: CN202223259256.3) authorized by China discloses a welding fixture for automobile battery box, including a support plate, both sides of the support plate are provided with slide grooves that can assist sliding, the inner wall of the slide groove is clamped with a limit block, the outer surface of the limit block is sleeved with a push rod, the top of the support plate is fixedly connected with a guide groove that can assist sliding, the inner wall of the guide groove is clamped with a slidable guide block, and the top of the guide block is fixedly connected with a slidable fixed plate. Through the matching arrangement of the support plate and the support plate, the support angle of the support plate can be adjusted according to different welding requirements, so that the device is suitable for different welding requirements. Through the matching arrangement of the limit block and the push rod, the adjusted support plate can be easily fixed, thereby ensuring the overall support stability of the device;

[0004] Although the prior art can adjust the extension distance of the guide rod according to different shapes of battery boxes through the cooperation of the fixing sleeve and the guide rod, so as to ensure that different positions of the battery box can be pressed and fixed, during the fixing process, the staff needs to manually adjust the position of the guide rods one by one, and then manually fix the guide rods one by one, resulting in cumbersome operation and low efficiency. Therefore, in view of the above problems, a welding fixture for a new energy storage battery box is proposed. Summary of the invention

[0005] In order to make up for the shortcomings of the prior art and solve the problem that during the fixing process, the workers need to manually adjust the position of the guide rods one by one and then manually fix the guide rods one by one, resulting in cumbersome operation and low efficiency, the present invention proposes a welding tooling fixture for a new energy storage battery box.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a welding fixture for a new energy storage battery box body described in the present invention comprises a base; a table is fixedly installed on the top of the base, a guide groove is symmetrically opened on the top of the table, a sliding table is symmetrically slidably installed on the top of the guide groove, a synchronization component is arranged at the bottom of the sliding table, a fixing piece is evenly installed on one side of the sliding table, a fixing component for quickly fixing a workpiece is arranged on one end of the fixing piece close to the sliding table, a fixing plate is installed between the fixing pieces, the fixing plate is fixedly installed on the top of the table, and a control console is fixedly installed on one side of the table;

When one of the fixing parts abuts against the sliding table, the staff operates the control panel to make the control panel generate a signal to control the motor to start. The motor drives the sealing block to abut against the inner wall of the sealing groove through the bidirectional lead screw, the first spring, the slide plate and the extrusion plate, thereby fixing the position of the fixing part and then fixing the workpiece. Compared with the prior art, it avoids the need for the staff to manually adjust the position of the fixing plate separately and then manually fix the fixing plate in turn during the process of fixing the workpiece, which causes cumbersome operation and low efficiency. It reduces the operating steps and improves work efficiency.

[0008] Preferably, the protection component includes a driving block arranged on one side of the skateboard, and driving gears are rotatably installed on both sides of the driving block, and slide grooves are arranged on the bottom ends of the driving gears, and the slide grooves are opened at the top of the table, and driving racks are fixedly installed on the inner walls of the slide grooves, and the driving gear is meshingly connected with the driving rack, and a curved rod is fixedly installed on one side of the driving gear, and a connecting plate is fixedly installed on the end of the curved rod away from the driving gear, and a protective plate is installed on the surrounding side of the connecting plate; by providing the protection component, the problem that when the fixing plate abuts against both sides of the workpiece and squeezes and fixes the workpiece, it is avoided that the workpiece is easily bent and folded, causing damage to the workpiece and affecting the quality of the finished product is avoided, the fixing effect of the workpiece is further improved, the damage to the workpiece during the processing is reduced, and the quality of the finished product is improved.

[0009] Preferably, the synchronization component includes a synchronization tooth plate arranged at the bottom end of the sliding table, one side of the synchronization tooth plate is meshingly installed with a synchronization gear, and the synchronization tooth plate is symmetrically installed with the synchronization gear as the center; it can avoid the difficulty in ensuring that the two sliding tables move the same distance when pushing the sliding table to adjust the position of the fixed part, resulting in unequal pressure on both sides of the workpiece, thereby reducing the fixing effect of the fixing component on the workpiece, and easily causing the problem of damage to the workpiece, thereby improving the fixing effect of the fixing component on the workpiece, thereby improving the welding effect of the workpiece and improving the quality of the new energy battery case.

[0010] Preferably, a guide rod is fixedly installed on one side of the extrusion plate away from the sealing block, the first spring is wound around the outer wall of the guide rod, and one end of the guide rod passes through the slide plate and extends to one side of the slide plate; this can prevent the first spring from being easily bent or deformed when the extrusion plate and the slide plate move, thereby affecting the use effect of the device and reducing the service life of the device, thereby improving the reliability and stability of the first spring during operation and increasing the service life of the device.

[0011] Preferably, connecting curved blocks are fixedly installed at both ends of the connecting plate, and the connecting curved blocks are slidably installed on the inner wall of the curved groove, and the curved grooves are opened at both ends of the inner wall of the protection plate, and the connecting plate and the protection plate are connected by a second spring, and the second spring is symmetrically installed between the connecting plate and the protection plate, and the inner wall of the protection plate away from the connecting plate is symmetrically fixed with protective curved blocks, and the second springs are wound around the outer walls of the protective curved blocks, and the protective curved blocks are slidably installed on the inner wall of the hole groove, and the hole groove is opened on one side of the connecting plate; this can avoid the situation where, when the workpiece is small, after the protective plate abuts against the top of the workpiece, it is still necessary to push the fixing part to adjust the position of the fixing plate, so that the protective plate continues to exert pressure on the workpiece, which easily causes deformation and damage of the workpiece, thereby improving the applicability of the device.

[0012] Preferably, the distance between the two ends of the guide rod is greater than the maximum distance between the slide plate and the extrusion plate; this can prevent one end of the guide rod from moving to the side of the slide plate close to the extrusion plate when the extrusion plate moves, thereby stopping the guiding effect on the extrusion plate; and when the slide plate moves, one end of the guide rod is likely to squeeze the first spring, causing the first spring to bend or deform, thereby improving the reliability and stability of the device.

[0013] Preferably, the number of teeth on the driving rack is greater than one-fourth of the number of teeth on the outer wall of the driving gear; this can prevent the driving gear from rotating easily when the driving gear stops meshing with the driving rack, thereby reducing the pressure of the protection plate on the top of the workpiece, thereby affecting the protective effect on the workpiece, making the workpiece susceptible to bending and breakage due to pressure on both sides, thereby improving the protective effect on the workpiece and further improving the fixing effect on the workpiece.

[0014] Preferably, the portion of the curved rod close to the driving gear is set to be a longer straight shape, and the portion of the curved rod away from the driving gear is set to be an arc shape with a larger radius; this can avoid the problem that when the height of the side plate of the workpiece is high, the curved rod is easily touched by the side plate of the workpiece during rotation, causing movement interference, causing the side plate of the workpiece to bend and be damaged, thereby improving the applicability of the equipment.

[0015] Preferably, the curved groove and the protective curved block are both arranged in a curved shape, and the curvature of the curved groove and the protective curved block is the same as the curvature of the circular arc portion of the curved rod; this can avoid the problem that when the curved groove and the protective curved block are arranged in a vertical shape, the connecting curved block is easily abutted against the inner wall of the curved groove when moving, causing movement interference, and easily causing the second spring to have a larger elastic deformation on one side and a smaller elastic deformation on the other side, thereby causing uneven force on both sides and reducing the service life, thereby improving the reliability and stability of the device.

[0016] The present invention is beneficial in that:

[0017] 1. The present invention sets a fixing component. When the workpiece needs to be fixed, the staff can push the sliding table to make the fixing parts abut against the two sides of the workpiece. When one of the fixing parts abuts against the sliding table, the staff operates the control table to make the control table generate a signal to control the motor to start. The motor drives the sealing block to abut against the inner wall of the sealing groove through the bidirectional screw rod, the first spring, the slide plate and the extrusion plate, thereby fixing the position of the fixing part and then fixing the workpiece. Compared with the prior art, the present invention avoids the problem that the staff need to manually adjust the position of the fixing plate separately and then manually fix the fixing plate in turn during the process of fixing the workpiece, which causes cumbersome operation and low efficiency. The operation steps are reduced and the work efficiency is improved.

[0018] 2. The present invention sets a protection component. When the workpiece is fixed, the slide drives the driving block to move, and the driving block drives the protection plate to move through the driving gear, the driving rack, the curved rod and the connecting plate, so that the protection plate abuts against the top of the workpiece and cooperates with the fixed plate to squeeze the workpiece, thereby avoiding the problem that when the fixed plate abuts against both sides of the workpiece and squeezes and fixes the workpiece, the workpiece is easily bent and folded, causing damage to the workpiece and affecting the quality of the finished product. The fixing effect of the workpiece is further improved, the damage to the workpiece during the processing is reduced, and the quality of the finished product is improved.

[0032] See also Figure 4-5 As shown, the synchronization component 400 includes a synchronization tooth plate 401 arranged at the bottom end of the sliding table 103, and a synchronization gear 402 is meshed and installed on one side of the synchronization tooth plate 401, and the synchronization tooth plate 401 is symmetrically installed with the synchronization gear 402 as the center; by setting the synchronization component 400, when one of the sliding tables 103 is pushed to adjust the position of the fixing member 104, the sliding table 103 drives the synchronization tooth plate 401 to move, the synchronization tooth plate 401 drives the synchronization gear 402 to rotate, the synchronization gear 402 drives the other synchronization tooth plate 401 to move, and the synchronization tooth plate 401 drives the sliding table 103 to move, so that the two sliding tables 103 move the same distance, avoiding the difficulty in ensuring that the two sliding tables 103 move the same distance when pushing the sliding table 103 to adjust the position of the fixing member 104, resulting in unequal pressure on both sides of the workpiece, thereby reducing the fixing effect of the fixing component 200 on the workpiece, and easily causing the problem of damage to the workpiece, thereby improving the fixing effect of the fixing component 200 on the workpiece, thereby improving the welding effect of the workpiece, and improving the quality of the new energy battery box.

[0033] See also Figure 1-6As shown, a guide rod 209 is fixedly installed on one side of the extrusion plate 204 away from the sealing block 203, and the first spring 206 is wound around the outer wall of the guide rod 209, and one end of the guide rod 209 passes through the slide plate 205 and extends to one side of the slide plate 205; the guide rod 209 and the slide plate 205 cooperate with each other to provide a guiding effect for the extrusion plate 204, and at the same time, the first spring 206 can be protected when the slide plate 205 and the extrusion plate 204 move, thereby avoiding the problem that the first spring 206 is easily bent and deformed when the extrusion plate 204 and the slide plate 205 move, thereby affecting the use effect of the device and reducing the service life of the device, thereby improving the reliability and stability of the first spring 206 during operation and increasing the service life of the device.

[0034] See also Figure 7 As shown, both ends of the connecting plate 306 are fixedly installed with connecting curved blocks 308, and the connecting curved blocks 308 are slidably installed on the inner wall of the curved groove 309. The curved grooves 309 are opened at both ends of the inner wall of the protection plate 307. The connecting plate 306 and the protection plate 307 are connected by a second spring 310. The second spring 310 is symmetrically installed between the connecting plate 306 and the protection plate 307. A protective curved block 311 is symmetrically fixedly installed on one side of the inner wall of the protection plate 307 away from the connecting plate 306. The second spring 310 is wound around the outer wall of the protective curved block 311. The protective curved block 311 is slidably installed on the inner wall of the hole groove 312. 12 are both opened on one side of the connecting plate 306; when the workpiece is small, the fixing assembly 200 needs to move a longer distance. At this time, the protection plate 307 abuts against the top of the workpiece, the curved rod 305 squeezes the connecting plate 306, and the connecting plate 306 squeezes the second spring 310, so that the second spring 310 undergoes elastic deformation and accumulates elastic potential energy, which avoids the situation that when the workpiece is small, after the protection plate 307 abuts against the top of the workpiece, it is still necessary to push the fixing member 104 to adjust the position of the fixing plate 105, so that the protection plate 307 continues to apply pressure to the workpiece, which easily causes deformation and damage of the workpiece, thereby improving the applicability of the device.

[0035] See also Figure 1-6 As shown, the distance between the two ends of the guide rod 209 is greater than the maximum distance between the slide plate 205 and the extrusion plate 204; when the extrusion plate 204 moves, the guide rod 209 can be kept sliding on the inner wall of the slide plate 205, avoiding that when the extrusion plate 204 moves, one end of the guide rod 209 moves to the side of the slide plate 205 close to the extrusion plate 204, thereby stopping the guiding effect on the extrusion plate 204, and when the slide plate 205 moves, one end of the guide rod 209 is easy to squeeze the first spring 206, causing the first spring 206 to bend and deform, thereby improving the reliability and stability of the device.

[0036] See also Figure 4 and Figure 6As shown, the number of teeth on the driving rack 304 is greater than one-fourth of the number of teeth on the outer wall of the driving gear 302; it can ensure that the curved rod 305 drives the connecting plate 306 and the protective plate 307 to rotate forty-five degrees, and when the workpiece is small, the protective plate 307 always squeezes the workpiece during the movement of the fixing member 104, thereby avoiding that when the driving gear 302 stops meshing with the driving rack 304, the driving gear 302 is easy to rotate, which reduces the pressure of the protective plate 307 on the top of the workpiece, thereby affecting the protection effect of the workpiece, making the workpiece easy to bend and break due to pressure on both sides, thereby improving the protection effect of the workpiece and further improving the fixing effect of the workpiece.

[0037] See also Figure 1 , Figure 2 , Figure 4 and Figure 7 As shown, the portion of the curved rod 305 close to the driving gear 302 is set to be a longer straight shape, and the portion of the curved rod 305 away from the driving gear 302 is set to be an arc shape with a larger radius; when the height of the side plate of the workpiece is relatively high, the curved rod 305 can cross the side plate to apply pressure to the top of the workpiece, thereby avoiding the problem that the curved rod 305 easily touches the side plate of the workpiece during rotation when the height of the side plate of the workpiece is relatively high, causing movement interference, causing the side plate of the workpiece to bend and be damaged, thereby improving the applicability of the equipment.

[0038] See also Figure 7 As shown, the curved groove 309 and the protective curved block 311 are both arranged to be curved, and the curvature of the curved groove 309 and the protective curved block 311 is the same as the curvature of the arc portion of the curved rod 305; the connecting plate 306 and the second spring 310 can be moved along the motion trajectory of the curved rod 305, avoiding the problem that when the curved groove 309 and the protective curved block 311 are arranged to be vertical, the connecting curved block 308 is easily abutted against the inner wall of the curved groove 309 when moving, causing motion interference, and easily causing one side of the second spring 310 to have a larger elastic deformation and the other side to have a smaller elastic deformation, thereby causing uneven force on both sides and reducing the service life, thereby improving the reliability and stability of the device.

[0039] Working principle: Before welding the workpiece, the workpiece is placed on the top of the fixed plate 105, and the staff pushes one of the sliding tables 103, so that the sliding table 103 drives the fixing part 104 to move, so that the fixing part 104 abuts against one side of the workpiece and adjusts the position according to the shape of the workpiece. At the same time, the sliding table 103 drives the synchronous gear plate 401 to move in the direction close to the synchronous gear 402, and the synchronous gear plate 401 drives the synchronous gear 402 to rotate, and the synchronous gear 402 drives another synchronous gear plate 401 to move, so that the other synchronous gear plate 401 drives another sliding table 103 to move, so that the two sliding tables 103 move the same distance, ensuring that the forces on both sides of the workpiece are equal;

[0040] When one of the fixing parts 104 contacts the sliding table 103, the staff member operates the control panel 106 to generate a signal to start the motor 208, so that the motor 208 drives the bidirectional screw rod 207 to rotate, and the bidirectional screw rod 207 drives the slide plate 205 to move in the direction close to the workpiece, and the slide plate 205 squeezes the first spring 206, so that the first spring 206 pushes the squeeze plate 204 to move, and the squeeze plate 204 drives the sealing block 203 to move, so that the sealing block 203 contacts the inner wall of the sealing groove 202, thereby the fixing plate 105 is pressed by air pressure. The workpiece is fixed, and the slide plate 205 drives the driving block 301 to move, and the driving block 301 drives the driving gear 302 to move, so that the driving rack 304 drives the driving gear 302 to rotate, and the driving gear 302 drives the crankshaft 305 to rotate, and the crankshaft 305 drives the connecting plate 306 to rotate in the direction close to the workpiece, and the connecting plate 306 squeezes the second spring 310, and the second spring 310 pushes the protection plate 307 to move, so that the protection plate 307 abuts against the top of the workpiece, and cooperates with the fixing plate 105 to squeeze and fix the workpiece;

[0041] When the workpiece is small, the staff can first operate the control console 106 so that the control console 106 generates a signal to start the motor 208, so that the motor 208 drives the fixing member 104 to move through the bidirectional screw rod 207, the slide plate 205, the first spring 206, the extrusion plate 204 and the sealing tube 201, thereby preliminarily adjusting the position of the fixing member 104 and the fixing plate 105 according to the size of the workpiece.
