Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a welding auxiliary device for a battery bracket of a new energy electric bus. Background Technology

[0002] With the booming development of the new energy vehicle industry, the application of new energy electric buses is becoming increasingly widespread. As a core component of the vehicle, the quality of the battery bracket directly affects the stability and safety of the battery, thus impacting the overall vehicle performance. Welding is a critical step in the manufacturing process of the battery bracket, but many technical challenges in this area remain to be solved.

[0003] Traditional welding processes suffer from poor positioning accuracy when welding battery brackets. Due to the lack of effective positioning methods, it is difficult to precisely align the various components of the battery bracket during welding, resulting in significant dimensional deviations after welding and affecting the battery's installation compatibility. For example, if the relative positions of different parts of the bracket deviate during welding, the battery may not fit snugly with other vehicle structures after installation, and may even become loose, posing a safety hazard while the vehicle is in motion.

[0004] Furthermore, manual welding operations make it difficult to monitor the accuracy of the welding position in real time and to adjust deviations promptly, further hindering the improvement of welding quality. Therefore, developing a welding auxiliary device that can accurately position, stably clamp, flexibly adapt to different specifications of battery trays, and has real-time monitoring capabilities has become an urgent need in the industry. Utility Model Content

[0005] The purpose of this invention is to provide a welding auxiliary device for battery brackets of new energy electric buses, which solves the above-mentioned problems.

[0006] This utility model is achieved through the following technical solution:

[0007] A welding auxiliary device for a battery bracket of a new energy electric bus includes a bottom. Two parallel base plate grooves are formed on the upper surface of the bottom. Threaded rods and guide rods of movable blocks are respectively arranged parallel within the two base plate grooves. The threaded rods pass through the groove walls and connect to a rotary motor on the side of the base plate. A fixed upright plate is formed on the upper surface of the bottom, opposite to the two movable blocks within the two base plate grooves. Both movable blocks are fixedly connected to the fixed upright plate. Alignment slots are formed on the opposite sides of the fixed upright plate and the bottom at corresponding left and right positions. Limiting clamp assemblies are provided above the two alignment slots, near the edges of the fixed upright plate and the moving upright plate. Two vertical grooves are formed between the two limiting clamp assemblies on the moving upright plate and the fixed upright plate, and adjustment components are arranged within the vertical grooves.

[0008] Furthermore,

[0009] The limiting clamp assembly includes a limiting motor, a clamping screw, a clamp, and a limiting groove. The limiting motor is located on the side of the movable upright plate and the fixed upright plate, and a limiting groove is opened corresponding to the limiting motor. The clamping screw connected to the limiting motor is set in the limiting groove. The clamp is divided into a fixed part and a movable part. The movable part is set on the clamping screw, and the fixed part is set on one side of the limiting groove so that the fixed part and the movable part are opposite to each other.

[0010] Furthermore,

[0011] The adjustment assembly includes an adjustment motor, a vertical lead screw, a slider, an electric telescopic rod, an extension block, an extension groove, an extension motor, a moving plate, and an extension lead screw. The adjustment motor is located at the top of the moving plate and the fixed plate, corresponding to the vertical groove. A vertical lead screw connected to the adjustment motor is installed in the vertical groove. A slider is fitted onto the vertical lead screw. An electric telescopic rod is vertically installed on the side of the slider facing outward from the vertical groove. The end of the electric telescopic rod is vertically connected to the extension block. An extension groove parallel to the base plate is opened on the outer surface of the extension block. An extension lead screw is installed parallel to the base plate in the extension groove. One end of the extension lead screw is connected to the extension motor. A horizontal moving plate is also fitted onto the extension lead screw.

[0012] Furthermore,

[0013] The upper surface of the moving plate has shallow arc-shaped grooves in its length and width directions, and a laser emitter and a laser receiver are provided on the lower surface of the moving plate.

[0014] Furthermore,

[0015] The alignment slots on the movable and fixed uprights should be located above the grooves between the two base plates.

[0016] Furthermore,

[0017] The normal length of the electric telescopic rod allows the moving plate and the limiting clamp assembly to be in the same plane.

[0018] Furthermore,

[0019] The emitting end of the laser emitter is oriented parallel to the length or width of the base plate. The laser receivers on the lower surface of the same moving plate are set perpendicular to the laser emitter, and the laser emitter of one moving plate corresponds to the laser receiver of another moving plate.

[0020] The beneficial effects of this utility model are:

[0021] 1. High-precision positioning and clamping: The moving plate and the fixed plate are driven to move relative to each other by the bottom threaded rod, guide rod and rotary motor. Combined with the mechanical positioning reference of the alignment slot, the horizontal position of the workpiece is accurately adjusted and aligned. The limit clamping assembly adopts the lead screw drive. The distance between the fixed part and the moving part of the clamp is controlled by the limit motor to ensure uniform and stable clamping force, avoid the workpiece displacement due to vibration or force during the welding process, and ensure welding accuracy.

[0022] 2. Flexible adjustment in three-dimensional space: The adjustment component integrates a vertical lead screw (Z-axis), an electric telescopic rod (Y-axis), and an extension lead screw (X-axis). Through the coordinated drive of the adjustment motor and the extension motor, the moving plate can be precisely positioned in three-dimensional space to adapt to battery brackets of different specifications and welding positions, significantly improving the versatility and applicability of the device.

[0023] 3. Adaptability to curved and flat surface welding: The shallow arc groove on the upper surface of the moving plate can fit the curved or arc structure of the battery bracket, providing a stable support and positioning reference; when welding the flat plate, the electric telescopic rod keeps the moving plate and the limit clamp assembly on the same horizontal plane, which also has the function of flat load bearing and meets diverse welding needs.

[0024] 4. Laser-assisted real-time calibration: The laser emitter and receiver on the lower surface of the moving plate are cross-arranged to form a two-dimensional positioning network, which detects the positional deviation of the bracket in real time. When the bracket shifts, the laser signal changes and is fed back to the control system, driving the adjustment components to automatically correct the position, achieving high-precision calibration of the welding position, reducing manual measurement errors, and improving the degree of automation.

[0035] Example

[0036] See Figures 1 to 4 :

[0037] A welding auxiliary device for a battery bracket of a new energy electric bus includes a bottom 1. Two parallel bottom plate grooves 10 are formed on the upper surface of the bottom 1. Threaded rods 12 and guide rods 13 of movable blocks 11 are respectively arranged parallel to each other in the two bottom plate grooves 10. The threaded rods 12 pass through the groove walls and are connected to a rotary motor 14 on the side of the bottom plate. A fixed upright plate 2 is formed on the upper surface of the bottom 1, opposite to the two movable blocks 11 in the two bottom plate grooves 10. Both movable blocks 11 are fixedly connected to the movable upright plate 2. Alignment slots 4 are formed on the movable upright plate 3 and the fixed upright plate 2 at corresponding left and right positions on their opposite surfaces. Limiting clamp assemblies 5 are set above the two alignment slots 4, near the edges of the movable upright plate 3 and the fixed upright plate 2. Two vertical grooves 6 are formed between the two limiting clamp assemblies 5 on the movable upright plate 3 and the fixed upright plate 2. Adjustment components 7 are set in the vertical grooves 6.

[0038] The threaded rod 12 and guide rod 13 in the groove 10 of the base plate are driven by the rotary motor 14, causing the moving block 11 to translate along the groove, which in turn drives the moving upright plate 3 to move relative to the fixed upright plate 2, thereby adjusting the horizontal position of the workpiece (battery bracket). The alignment slot 4 ensures that the moving upright plate 3 and the fixed upright plate 2 remain vertically aligned during movement. The limiting clamp assembly 5 is used to clamp the workpiece, and the adjustment assembly 7 in the vertical groove 6 is responsible for vertical position adjustment.

[0039] Furthermore,

[0040] The limiting clamp assembly 5 includes a limiting motor 50, a clamping screw 51, a clamp 52, and a limiting groove 53. The limiting motor 50 is disposed on the side of the movable upright plate 3 and the fixed upright plate 2, and a limiting groove 53 is opened corresponding to the limiting motor 50. The clamping screw 51 connected to the limiting motor 50 is disposed in the limiting groove 53. The clamp 52 is divided into a fixed part 520 and a movable part 521. The movable part 521 is disposed on the clamping screw 51, and the fixed part 520 is disposed on one side of the limiting groove 53 so that the fixed part 520 and the movable part 521 are opposite to each other.

[0041] The rotation of the clamping screw 51 is controlled by the forward and reverse rotation of the limit motor 50, which drives the moving part 521 to move linearly within the limit groove 53, thereby adjusting the distance between the fixed part 520 and the moving part 521, and realizing the clamping or loosening of the battery bracket to be welded. This structure utilizes the high precision characteristics of the screw drive to ensure uniform and stable clamping force and avoids displacement of the workpiece due to vibration or force during the welding process.

[0042] Furthermore,

[0043] The adjustment assembly 7 includes an adjustment motor 70, a vertical lead screw 71, a slider 72, an electric telescopic rod 73, an extension block 74, an extension groove 75, an extension motor 76, a moving plate 77, and an extension lead screw 78. The adjustment motor 70 is located on the top of the moving plate 3 and the fixed plate 2 and corresponds to the vertical groove 6. The vertical groove 6 contains the vertical lead screw 71 connected to the adjustment motor 70. The slider 72 is fitted onto the vertical lead screw 71. The electric telescopic rod 73 is vertically installed on the side of the slider 72 facing outward from the vertical groove 6. The end of the electric telescopic rod 73 is vertically connected to the extension block 74. An extension groove 75 parallel to the bottom plate is opened on the outer surface of the extension block 74. The extension lead screw 78 is parallel to the expansion groove 75. One end of the extension lead screw 78 is connected to the extension motor 76. A horizontal moving plate 77 is also fitted onto the extension lead screw 78.

[0044] The adjusting motor 70 drives the vertical lead screw 71 to rotate, causing the slider 72 to move up and down (Z-axis direction) within the vertical groove 6; the electric telescopic rod 73 connects the slider 72 and the extension block 74, achieving horizontal displacement (Y-axis) through extension and retraction; the extension motor 76 drives the extension lead screw 78, causing the moving plate 77 to move laterally (X-axis direction) within the extension groove 75. The coordinated action of these three components allows the moving plate 77 to flexibly adjust its position in three-dimensional space, adapting to the welding requirements of battery trays of different specifications.

[0045] Furthermore,

[0046] The upper surface of the movable plate 77 has an arc-shaped shallow groove 770 in its length and width directions, and a laser emitter 771 and a laser receiver 772 are provided on the lower surface of the movable plate 77.

[0047] The arc-shaped shallow groove 770 provides an arc-shaped positioning reference for the bracket components, adapting to the curved surface or arc structure of the battery bracket and enhancing contact stability. The laser emitter 771 emits a beam along the length / width direction of the base plate, and the receiver is set vertically to detect the positional deviation of the bracket through laser beam detection. When the bracket is placed on the moving plate 77, if the position is offset, the laser signal is blocked or the received intensity changes. The system then calibrates the welding path in real time to ensure accurate weld point positioning.

[0048] Furthermore,

[0049] The alignment slots 4 on the movable upright plate 3 and the fixed upright plate 2 should be located above the grooves 10 on the two base plates.

[0050] The alignment slot 4 serves as a mechanical positioning reference, ensuring the relative positional accuracy of the moving upright plate 3 and the fixed upright plate 2 in the horizontal direction (X-axis), and avoiding clamping or adjustment failures caused by installation deviations.

[0051] Furthermore,

[0052] The normal length of the electric telescopic rod 73 allows the moving plate 77 and the limiting clamp assembly 5 to be in the same plane.

[0053] Under normal conditions, the electric telescopic rod 73 maintains a preset length, so that the moving plate 77 and the limit clamp assembly 5 are on the same horizontal plane, which facilitates the quick installation and initial positioning of the bracket components; when it is necessary to adjust the height or expand the working range, the telescopic rod extends or shortens, causing the moving plate 77 to detach from or return to the reference plane, thereby realizing the function switching.

[0054] Furthermore,

[0055] The emitting end of the laser emitter 771 is oriented parallel to the length or width of the base plate. The laser receiver 772 on the lower surface of the same moving plate 77 is set perpendicular to the laser emitter 771, and the laser emitter 771 of one moving plate 77 and the laser receiver 772 of the other moving plate 77 correspond to each other.

[0056] A two-dimensional positioning network is formed by cross-arranged laser beams (such as X-direction transmitters paired with Y-direction receivers) to detect the positional deviation of the bracket in the plane in real time. When the bracket shifts in the X or Y direction, the corresponding laser signal is blocked. The system calculates the offset through signal feedback and drives the adjustment component 7 to correct the position, achieving high-precision positioning.

[0057] The principle of this utility model is as follows:

[0058] When using,

[0059] In use, the bottom 1 rotary motor 14 drives the threaded rod 12 to rotate, causing the movable upright plate 3 to move horizontally along the guide rod 13. The distance between the movable upright plate 3 and the fixed upright plate 2 is adjusted, and the bottom 1 crossbeam is aligned and fixed with the alignment slot 4. Then, the vertical beam is fixed with the limiting clamp assembly 5 to ensure that the two are perpendicular before welding. According to the welding position requirements on the vertical beam, the adjustment motor 70 drives the vertical lead screw 71 to make the slider 72 move up and down in the vertical groove 6. The electric telescopic rod 73 extends and retracts to achieve horizontal displacement. The extension motor 76 drives the extension lead screw 78 to move the movable plate 77 laterally, so that the arc-shaped shallow groove 770 on the movable plate 77 is aligned with the place to be welded. The laser emitter 771 on the lower surface of the movable plate 77 emits a beam along the length / width direction of the bottom plate. The vertically set laser receiver 772 corresponds across the plate to form a cross positioning network. When the receiver receives the laser, the feedback signal causes the adjustment motor 70 to stop operating, achieving precise alignment. If welding the vertical beam flat plate, the four movable plates 77 are on the same horizontal plane through the laser action, serving as a support plate to support the flat plate for welding. The principle is to use the transmission structure such as the threaded rod 12, guide rod 13, and lead screw to realize the horizontal, vertical, and lateral movement of the moving upright plate 3 and the moving plate 77. The workpiece is clamped by the limit clamping fixture assembly 5, and the three-dimensional spatial position is adjusted by the electric telescopic rod 73. The arc-shaped shallow groove 770 fits the bracket contour to provide stable support. Through the signal feedback of the laser emitter 771 and the receiver, the bracket position deviation is detected and calibrated in real time to ensure that the bracket is in the precise welding position, thereby completing the welding work of the battery bracket of the new energy electric bus efficiently and accurately.

[0060] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
