Description

Technical Field

[0001] This utility model relates to the field of sawing equipment technology, and more specifically, to a sawing device for automobile battery beams. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the safety, reliability, and energy density of battery packs, as the core power source of vehicles, have increasingly become the focus of attention. Battery packs typically consist of multiple battery modules, which are supported, fixed, and connected by battery beams (or battery box longitudinal beams and transverse beams). Battery beams are generally long, narrow profiles (such as aluminum profiles), and various holes, slots, or end faces cut at specific angles need to be machined along their length to accommodate other components or meet lightweight structural requirements.

[0003] In existing technologies, the main methods for sawing and drilling battery beams are as follows: 1) Manual fixing and handling: Operators place the battery beam on a regular workbench, manually clamp and position it using simple fixtures, and then use handheld sawing equipment (such as an angle grinder) or transport the workpiece to a fixed saw for processing. This method has the following disadvantages: First, the positioning accuracy is poor, relying on the operator's experience, resulting in low product quality consistency; second, the safety is poor, as handheld high-speed rotating sawing equipment poses a high risk to operators; finally, the production efficiency is low and cannot meet the needs of modern mass production. 2) Dedicated fixed CNC saw: Some manufacturers use CNC saws for automated sawing. Although the processing accuracy and safety are improved, such equipment can usually only perform sawing at fixed angles (such as 90° right angle cuts). When it is necessary to process non-right angles (such as 45°, 60°, etc.) on the battery beam, the fixture must be loosened, the workpiece angle readjusted, and the fixture repositioned and clamped. This reclamping process is not only time-consuming and labor-intensive, but it is also difficult to ensure the consistency of the machining datum after the two clampings, which affects the assembly accuracy of the product.

Detailed Implementation

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.

[0025] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0026] This utility model provides a sawing device for automotive battery beams, such as... Figure 1As shown, it includes: a clamping base 1, which is rotatably connected to the housing 4; the clamping base 1 has a processing window 101 for the battery beam to pass through, the shape of the processing window 101 including but not limited to rectangle, circle, etc., generally set according to the outer contour of the workpiece to be processed; the clamping base 1 is provided with multiple chuck assemblies 102 and multiple first linear drive assemblies 103; each chuck assembly 102 is respectively connected to a first linear drive assembly 103, so that the chuck assembly 102 clamps or releases the battery beam passing through the processing window 101; a moving mechanism 2, the moving mechanism 2 including a second linear drive assembly 201 with a second output end; the second output end is fixedly connected to the housing 4, so as to move the housing 4 and the clamping base 1 to the processing position of the battery beam; the battery beam is transported over... The position may not always accurately pass through the processing window 101. The function of the moving mechanism 2 is to adjust the position of the processing window 101. Specifically, the moving mechanism 2 moves the housing 4 and the clamping base 1 in a direction perpendicular to the conveying direction of the battery beam, so that the processing window 101 can be adjusted and aligned with the battery beam, facilitating the subsequent clamping of the battery beam by the chuck assembly 102. The rotating mechanism 3 includes a third power component 301. The third power component 301 has a third output end. The third output end is connected to the clamping base 1 in a transmission manner to make the clamping base 1 rotate. The sawing device 5 is used to saw the battery beam. The sawing device 5 is generally a laser cutting device, which is connected in communication with the control system to cut the required grooves or cut off the battery beam.

[0027] Regarding the fixing of the clamping base 1 and the bearing 104: the outer peripheral wall of the clamping base 1 is fixed to the inner ring of the bearing 104; the outer ring of the bearing 104 is fixed to the housing 4 so that the clamping base 1 can rotate within the housing 4; when the battery beam needs to be flipped for cutting, after the chuck 1022 clamps the battery beam, the third servo motor drives the gear to rotate, thereby driving the clamping base 1 to rotate to the required angle, so that the sawing device 5 can saw the battery beam. A gear ring 105 is fixed to the outer peripheral wall of the clamping base 1; the third power component 301 is a third servo motor, and the third output end is a third output shaft; a gear is fixed to the third output shaft, and the gear meshes with the gear ring 105 so that the third servo motor drives the clamping base 1 to rotate; when the battery beam needs to be flipped to different surfaces for cutting, the control system controls multiple chucks 1022 to clamp the battery beam, and then the third servo motor drives the gear to rotate, thereby driving the clamping base 1 to rotate to the required angle, so that the battery beam is flipped to the surface to be processed, thereby enabling the sawing equipment 5 to perform cutting operations on the battery beam.

[0028] In one embodiment, such as Figure 3 , 5As shown, the first linear drive assembly 103 includes a first servo motor 1031 with a first output end; a first lead screw is fixedly connected to the first output end; the first lead screw is driven to a first slide block 1032, so that the first servo motor 1031 drives the first slide block 1032 to reciprocate; the first servo motor 1031 is communicatively connected to the control system, and the control system independently controls each first servo motor 1031, thereby independently controlling the movement distance of each clamp assembly 102. It can adapt to battery beams of various sizes, has strong versatility, and because it uses servo motors, it can accurately control the movement distance of each clamp assembly 102; while existing clamp assemblies 102 often use a synchronization mechanism to make multiple clamp assemblies 102 move synchronously. This design is often suitable for objects with relatively uniform size, such as those with a square cross-section.

[0029] In one embodiment, such as Figures 5-6 As shown, two pairs of chuck assemblies 102 are orthogonally arranged in the horizontal and vertical directions, respectively. From a top view, the pair of chuck assemblies 102 in the horizontal direction are at the same depth, while the pair of chuck assemblies 102 in the vertical direction are at another same depth. The depth referred to here is the depth to which the battery beam passes through the processing window 101 of the clamping base 1. The two pairs of chuck assemblies 102 are staggered to avoid mutual interference.

[0030] In one embodiment, such as Figures 5-6 As shown, the clamp assembly 102 includes a mounting base 1021; the mounting base 1021 has at least one clamp 1022 for clamping and releasing the battery beam. The clamp 1022 has a columnar structure and makes line contact with the battery beam; the clamp 1022 is fixedly or rotatably connected to the mounting base 1021.

[0031] In one embodiment, such as Figure 3As shown, the second linear drive assembly 201 includes a second servo motor 202 and a mounting bracket. The second output shaft of the second servo motor 202 is connected to a second lead screw via a synchronous belt drive. The second lead screw is rotatably connected to the mounting bracket. A second slide block 203 is drivenly connected to the second lead screw. Specifically, the second slide block 203 has a threaded hole, so that the second lead screw is threadedly connected to the second slide block 203. When the second servo motor 202 works, it drives the second lead screw to rotate, thereby driving the second slide block 203 to move, and thus moving the housing 4 and the clamping base 1 to a suitable position to clamp the battery beam. Guide rods can also be provided on both sides of the second lead screw to slide and engage with the second slide block 203 to guide the movement of the second slide block 203. In this application, the threaded connection method and the guide rod method can be used wherever the lead screw and the slide block are used. The second slide block 203 is fixedly connected to the housing 4 and the third power assembly 301 respectively, so that when the second servo motor 202 works, it can drive the housing 4 and the third power assembly 301 to move together to the position of the battery beam.

[0032] In one embodiment, such as Figure 1 As shown, the automotive battery beam sawing device also includes a fourth linear drive mechanism for driving the sawing device 5 to move vertically; the fourth linear drive mechanism includes a fourth servo motor 6; a fourth lead screw is fixed to the fourth output shaft of the fourth servo motor 6; the fourth lead screw is connected to a fourth slide block 601, and the fourth slide block 601 is adjusted by the operation of the fourth servo motor 6 driving the fourth lead screw to rotate, thereby adjusting the height of the fourth slide block 601, and thus adjusting the height of the sawing device 5 when performing the cutting operation; a guide rail 602 is vertically fixed to the fourth slide block 601; the sawing device 5 is fixed on the guide rail 602, and the guide rail 602 mainly ensures that the sawing device 5 is not easily deviated in the vertical direction.

[0033] In one embodiment, such as Figure 1 As shown, the automotive battery beam sawing device also includes a fifth linear drive mechanism; the fifth linear drive mechanism includes a fifth servo motor; the fifth output shaft of the fifth servo motor is fixedly connected to a fifth lead screw 7; the fifth lead screw 7 is driven by a fifth slide block 701; the fourth linear drive mechanism is fixed to the fifth slide block 701, and drives the fifth lead screw 7 to rotate through the fifth servo motor, thereby driving the fifth slide block 701 to move in the horizontal direction, which is perpendicular to the battery beam conveying direction, as shown. Figure 1 As shown; of course, the car battery beam sawing device may also include a sixth linear drive mechanism, which is not shown in the figure. The sixth linear drive mechanism also adopts the above-mentioned method of fixing the lead screw at the output end of the servo motor and connecting the lead screw to the slide block. The fifth linear drive mechanism is fixed on the slide block of the sixth linear drive mechanism. The direction of movement of the slide block is parallel to the conveying direction of the battery beam, so that the sawing device 5 can not only work in the vertical direction, but also in the horizontal and longitudinal directions.

[0034] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
