Description

Technical Field

[0001] This utility model relates to the field of battery water-cooled plate processing technology, specifically a laser welding device for a clampable and rotatable battery water-cooled plate. Background Technology

[0002] Battery water-cooled plates use water as a cooling medium, utilizing water's high specific heat capacity and excellent thermal conductivity to remove the heat generated by the battery during operation. Water-cooled plates are typically composed of multiple layers of materials, including cooling channels, heat sinks, and connection interfaces, ensuring that heat can be efficiently conducted from the battery to the cooling water and carried away by the water flow, thereby maintaining the battery within a suitable temperature range. The welding process of battery water-cooled plates is crucial to their sealing performance, thermal conductivity, and reliability. Water-cooled plates with different structures and materials require matching appropriate welding techniques.

[0003] During the welding process of existing battery water-cooled plates, a positioning device is required to limit the material. However, after the material is clamped and fixed, it is not easy to flip it over, which makes it difficult to adjust the processing angle and reduces the efficiency of the work. Utility Model Content

[0004] The purpose of this invention is to provide a laser welding device for battery water-cooled plates that can clamp and rotate, in order to solve the problem mentioned in the background art that after the raw materials are clamped and fixed, it is not easy to flip the raw materials, which makes it difficult to adjust the processing angle and reduces the efficiency of the work.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a laser welding device for clamping and rotating battery water-cooled plates, comprising a slide rail bracket, one end of which is fixedly connected to a fixed side plate, a movable side plate mounted on the outer surface of one end of the slide rail bracket, an adjusting push plate through the side surface of the slide rail bracket, a locking block through the upper surface of the slide rail bracket, a drive motor fixedly connected to the upper surface of the slide rail bracket, a drive gear fixedly connected to the output end of the drive motor, a supporting cylinder provided on the lower side surface of the fixed side plate, a linkage tooth block fixedly connected to the outer surface of the supporting cylinder, a linkage cylinder mounted on the lower side surface of the movable side plate, and a synchronous adjustment mechanism provided inside both the fixed side plate and the movable side plate. The mechanism drives two first sprockets to move via the supporting cylinder and the linkage cylinder, causing the first sprockets to drive a second sprocket and a mounting disc to rotate via a transmission chain, facilitating the adjustment of the workpiece angle.

[0006] Preferably, the slide rail bracket and the movable side plate are slidably connected, the lower surface of the movable side plate is provided with a groove, the adjusting push plate and the slide rail bracket are slidably connected, and a spring is connected between the adjusting push plate and the slide rail bracket.

[0007] The above technical solution allows the sliding connection design to allow the movable side plate to slide along the slide rail bracket, which is convenient for adapting to battery water-cooled plate raw materials of different sizes and expands the applicability of the device.

[0008] Preferably, the upper surface of the adjusting push plate is provided with an arc-shaped protrusion, the locking block and the slide rail bracket are slidably connected, and a spring is connected between the locking block and the slide rail bracket, and the lower surface of the locking block is inclined.

[0009] Using the above technical solution, when the movable side plate slides to the target position, the locking block is embedded in the groove of the movable side plate under the action of the spring. By utilizing the self-locking characteristics of the inclined surface, the movable side plate is prevented from shifting due to vibration and other factors during the processing, thus ensuring clamping stability.

[0010] Preferably, the supporting cylinder and the fixed side plate are rotatably connected, the driving gear and the linkage gear block are meshingly connected, the linkage cylinder and the movable side plate are rotatably connected, and the linkage cylinder and the supporting cylinder are slidably connected.

[0011] By adopting the above technical solution, the drive motor transmits power precisely to the support cylinder through the meshing of the drive gear and the linkage gear block, avoiding slippage and ensuring the accuracy and reliability of angle adjustment.

[0012] Preferably, the synchronous adjustment mechanism includes a first sprocket, two first sprockets are respectively fixed to one end of the supporting cylinder and the linkage cylinder, a second sprocket is provided on the inner wall of the cavity of the fixed side plate and the movable side plate, an installation disc is installed on the side surface of the fixed side plate and the movable side plate, a fastening screw is provided on the surface of the installation disc, and two clamping pressure plates are installed on the outer surface of the fastening screw.

[0013] Using the above technical solution, the first sprocket drives the second sprocket to rotate through the transmission chain, so that the two mounted discs rotate synchronously, ensuring that the workpiece can be flipped at any angle during the welding process without manual adjustment, thus improving processing efficiency.

[0014] Preferably, the two first sprockets are rotatably connected to the fixed side plate and the movable side plate respectively, and a transmission chain is provided between the first sprockets and the second sprockets.

[0015] By adopting the above technical solution, the transmission chain ensures that the speed ratio between the first sprocket and the second sprocket is constant, so that the rotation angle of the mounting disc is completely synchronized with the rotation angle of the supporting cylinder and the linkage cylinder, avoiding workpiece angle deviation due to transmission error and ensuring welding position accuracy.

[0016] Preferably, the two mounting discs are rotatably connected to the fixed side plate and the movable side plate, respectively. The mounting discs are rotatably connected to the fastening screws. The threads at both ends of the fastening screws are in opposite directions. The fastening screws are threadedly connected to the clamping pressure plate. The clamping pressure plate is slidably connected to the mounting discs.

[0017] The above technical solution features a reverse thread design at both ends of the screw. When the screw is rotated, the clamping plates on both sides move synchronously towards the center or the outside, ensuring that the workpiece is subjected to uniform force and avoiding deformation caused by unilateral extrusion. It is especially suitable for clamping thin or precision water-cooled plates.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the laser welding device for clamping and rotating battery water-cooling plates:

[0019] 1. By sliding the slide rail bracket and the movable side plate, the clamping distance can be quickly adjusted to accommodate battery water-cooled plate raw materials of different sizes. With the arc-shaped protrusion of the adjustment push plate and the inclined surface design of the locking block, it can realize convenient operation of one-handed pressing to unlock and spring reset to lock. During the adjustment process, the spring buffer force avoids rigid collision, and the locking block forms a self-lock after being embedded in the groove of the movable side plate, ensuring the stability of the workpiece position during welding. This solves the problems of fixed clamping size and cumbersome adjustment of traditional devices, and significantly improves clamping efficiency and reliability.

[0020] 2. The drive motor drives the support cylinder to rotate through the meshing of the drive gear and the linkage gear block. At the same time, the sliding connection design between the linkage cylinder and the support cylinder ensures that the transmission continuity can be maintained even when the distance between the moving side plates is adjusted. The transmission chain connecting the first sprocket and the second sprocket allows the synchronous adjustment mechanism in the fixed side plate and the moving side plate to drive the mounting discs on both sides to rotate synchronously, realizing the workpiece can be flipped at any angle of 360°. Compared with the disadvantage of traditional devices that require manual adjustment of angle one by one, this design can accurately and efficiently switch the welding position, reduce manual intervention, and improve processing efficiency and angle adjustment accuracy.

[0021] 3. The fastening screw on the mounting disc and the bidirectional threaded clamping plate form a modular clamping structure. When the screw is rotated, the two clamping plates on both sides clamp the workpiece simultaneously, ensuring uniform force and avoiding deformation of the thin water-cooled plate. The sliding guide design of the clamping plate and the disc further improves the clamping and positioning accuracy. The axial sliding capability of the linkage cylinder allows the device to adjust the clamping distance without re-aligning the transmission system, taking into account the adaptability of different workpiece specifications and the stability of the mechanical structure, thus achieving efficient operation.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6This utility model provides a technical solution: a laser welding device for clamping and rotating battery water-cooled plates, comprising a slide rail bracket 1, a fixed side plate 2, a movable side plate 3, an adjusting push plate 4, a locking block 5, a drive motor 6, a drive gear 7, a supporting cylinder 8, a linkage tooth block 9, a linkage cylinder 10, a first sprocket 11, a second sprocket 12, a mounting disc 13, a fastening screw 14, and a clamping pressure plate 15. The slide rail bracket 1 has a fixed side plate 2 fixedly connected to one end, and a movable side plate 3 is mounted on the outer surface of one end of the slide rail bracket 1. The slide rail bracket 1 and the movable side plate 3 are slidably connected. The lower surface of the movable side plate 3 is provided with a groove. The adjusting push plate 4 is slidably connected to the slide rail bracket 1. A spring connects the adjusting push plate 4 to the slide rail bracket 1. The slide rail bracket 1 serves as the basic support structure, with one end fixed to the fixed side plate 2 and the other end slidably connected to install the movable side plate 3. When the clamping distance needs to be adjusted, the movable side plate 3 is pushed to slide along the slide rail bracket 1. Its lower surface groove cooperates with the arc-shaped protrusion of the adjusting push plate 4 to achieve phased locking. After adjustment, the locking block 5 slides downward under the action of the spring. Its inclined lower surface is embedded in the groove of the movable side plate 3, using the inclined self-locking principle to fix the position and prevent the movable side plate 3 from shifting during welding. When readjustment is required, the adjusting push plate 4 is pressed, and its protrusion pushes the locking block 5 upward to compress the spring, releasing the lock, and the movable side plate 3 can slide again.

[0031] An adjusting push plate 4 is installed through the side surface of the slide rail bracket 1, and a locking block 5 is installed through the upper surface of the slide rail bracket 1. A drive motor 6 is fixedly connected to the upper surface of the slide rail bracket 1, and a drive gear 7 is fixedly connected to the output end of the drive motor 6. A supporting cylinder 8 is provided on the lower side surface of the fixed side plate 2. An arc-shaped protrusion is provided on the upper surface of the adjusting push plate 4. The locking block 5 and the slide rail bracket 1 are slidably connected, and a spring is connected between the locking block 5 and the slide rail bracket 1. The lower surface of the locking block 5 is inclined. The supporting cylinder 8 and the fixed side plate 2 are rotatably connected. The drive gear 7 and the linkage gear block 9 are meshed. The linkage cylinder 10 is rotatably connected to the movable side plate 3, and the linkage cylinder 10 is slidably connected to the support cylinder 8. After the drive motor 6 starts, it transmits power to the support cylinder 8 through the drive gear 7 at the output end meshing with the linkage gear block 9 on the support cylinder 8, causing it to rotate around the fixed side plate 2. The linkage cylinder 10 is rotatably connected to the movable side plate 3, and its lower end is slidably connected to the support cylinder 8. When the movable side plate 3 adjusts the spacing, the linkage cylinder 10 can move along the axial direction of the support cylinder 8 to maintain the transmission continuity with the support cylinder 8. The support cylinder 8 and the linkage cylinder 10 serve as power input shafts, driving the first sprocket 11 at one end of each to rotate.

[0032] A linkage toothed block 9 is fixedly connected to the outer surface of the supporting cylinder 8, and a linkage cylinder 10 is installed on the lower side surface of the movable side plate 3. The synchronous adjustment mechanism includes a first sprocket 11, with two first sprockets 11 fixed to one end of the supporting cylinder 8 and the linkage cylinder 10 respectively. A second sprocket 12 is provided on the inner wall of the cavity of the fixed side plate 2 and the movable side plate 3. An installation disc 13 is installed on the side surface of the fixed side plate 2 and the movable side plate 3. A fastening screw 14 is provided on the surface of the installation disc 13, and two clamping pressure plates 15 are installed on the outer surface of the fastening screw 14. The supporting cylinder 8 and the linkage cylinder 10 drive their respective first sprockets 11 to rotate. The first sprockets 11 drive the second sprockets 12 in the cavity of the fixed side plate 2 and the movable side plate 3 to rotate synchronously through the transmission chain. The second sprockets 12 are fixedly connected to the outer installation disc 13. Therefore, when the second sprocket 12 rotates, the installation disc 13 rotates accordingly, thereby realizing the angle adjustment of the workpiece.

[0033] Both the fixed side plate 2 and the movable side plate 3 are equipped with a synchronous adjustment mechanism. This mechanism, through the supporting cylinder 8 and the linkage cylinder 10, drives two first sprockets 11, causing them to rotate via a transmission chain. This facilitates the adjustment of the workpiece angle. The two first sprockets 11 are rotatably connected to the fixed side plate 2 and the movable side plate 3, respectively. A transmission chain connects the first sprockets 11 and the second sprockets 12. The two mounting discs 13 are rotatably connected to the fixed side plate 2 and the movable side plate 3, respectively. The mounting discs 13 are also rotatably connected to the fastening screws 14, whose threads at both ends are in opposite directions. The fastening screw 14 and the clamping pressure plate 15 are threaded together, and the clamping pressure plate 15 and the mounting disc 13 are slidably connected. When the fastening screw 14 is rotated, the clamping pressure plates 15 on both sides move closer or further away along the screw axis. The workpiece is clamped or released through the sliding connection with the mounting disc 13. During welding, the drive motor 6 drives the mounting disc 13 to rotate through the above-mentioned transmission chain system. The workpiece rotates with the disc to the target angle, and the laser welding head welds the joint of the water-cooled plate to complete multi-angle processing. After processing, the clamping pressure plate 15 is released and the locking block 5 is released in reverse order, and the workpiece can be removed and a new material can be replaced.

[0034] Working principle: When using this laser welding device for clamping and rotating battery water-cooled plates, the movable side plate 3 is pushed to slide along the slide rail bracket 1 to adjust the spacing. The arc-shaped protrusion of the adjusting push plate 4 is positioned in conjunction with the groove of the movable side plate 3. The locking block 5 is spring-driven and embedded in the groove to lock. The drive motor 6 drives the drive gear 7 to mesh with the linkage tooth block 9, causing the support cylinder 8 to rotate. The linkage cylinder 10 is slidably connected to the support cylinder 8, maintaining transmission as the spacing is adjusted. The first sprocket 11 at the end of the support cylinder 8 and the linkage cylinder 10 drives the second sprocket 12 through the transmission chain, causing the mounting disc 13 to rotate synchronously to adjust the workpiece angle. The rotating fastening screw 14 drives the clamping pressure plate 15 to clamp the workpiece synchronously through its reverse thread. After the mounting disc 13 drives the workpiece to rotate to the target angle, laser welding is performed, increasing the overall practicality.
