Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically to an integrated equipment for multi-station synchronous positioning fixtures for forefoot irons. Background Technology

[0002] As a core safety component of the braking system, the front shoe of an electric vehicle directly affects braking stability due to the welding quality of its horizontal and vertical curved panels. Furthermore, the use of lightweight materials such as high-strength aluminum alloy and low-alloy steel places stringent requirements on welding positioning accuracy, clamping compatibility, and processing efficiency.

[0003] Existing technologies for forefoot shoe processing have significant limitations: First, they mostly employ a single-station, step-by-step processing mode, requiring manual transfer of the workpiece between positioning, welding, grinding, and drilling processes. This results in long process intervals, low batch production efficiency, and the potential for positioning datum deviation due to manual intervention. Second, clamping mechanisms are mostly rigid designs, unable to adapt to the curvature tolerances of lightweight materials, easily causing workpiece deformation. Furthermore, insufficient welding positioning accuracy and uneven weld gaps lead to poor weld fusion, insufficient fatigue resistance, and corrosion resistance, making it difficult to meet the safety requirements of electric vehicle braking systems. Third, the equipment functions are fragmented, with clamping, welding, and drilling functions independently set up, resulting in a large footprint and complex piping. It also has narrow adaptability, requiring the replacement of the entire set of clamps for different forefoot shoe specifications, leading to high equipment investment and maintenance costs. Therefore, we propose an integrated multi-station synchronous positioning clamping device for forefoot shoes. Summary of the Invention

[0015] Compared with the prior art, the present invention provides an integrated device for multi-station synchronous positioning fixtures for forefoot horses, which has the following beneficial effects: 1. The electric turntable enables continuous multi-station operation, including "material loading and positioning, pre-welding pretreatment, synchronous welding of double weld seams, post-welding finishing, and drilling of assembly holes," eliminating the need for manual intervention in workpiece transfer and significantly reducing waiting time between processes, thus achieving continuous mass production. It integrates automated power distribution and motion coordination mechanisms, such as the first motor synchronously driving the drill bit rotation and the mounting box feed, and the fifth motor synchronously achieving flux stirring and reciprocating motion of the welding head. This avoids the inefficiency of a single power source driving a single action, increasing the processing capacity per unit time. The welding assembly adopts a dual-welding-head synchronous welding design, combined with the circular motion driven by the third motor, which can simultaneously complete the upper and lower double weld seams of the horizontal and vertical curved panels. Compared to traditional single-welding-head multi-stage welding, this shortens the welding cycle and meets the mass production needs of electric vehicle components.

[0016] 2. The flexible clamping of the arc-shaped clamping plate and the adaptive compensation of the rubber clips ensure uniform gaps between the welding surfaces of the horizontal and vertical curved panels. At the same time, the arc-shaped toothed rack meshes with the seventh gear to drive the sliding bracket to move along the arc trajectory, achieving precise alignment between pre-welding pretreatment and welding operations. During welding, the atomizing nozzle precisely sprays flux, which, together with the high-frequency reciprocating motion of the welding head, forms a fish-scale weld, enhancing the fatigue resistance of the weld. After welding, chamfering with grinding discs and cam slag cleaning avoid stress concentration and surface defects, ensuring that the components meet the safety strength requirements of electric vehicle braking systems. The elastic buffer structure of the spring limit rod can compensate for the slight displacement caused by welding thermal deformation in real time, and the low-stress clamping design of the rubber clips prevents deformation of lightweight materials due to excessive clamping force, ensuring the consistency of component dimensional accuracy.

[0017] 3. By adjusting the slide rail along the slide frame and adjusting the spacing of the moving blocks with the opposing threaded rod, it can adapt to the processing of front horseshoes with different arc radii and thicknesses without replacing the entire set of fixtures, reducing the equipment investment cost for multi-specification production; the integrated structural design enhances practicality: it integrates clamping, welding, grinding, and drilling functions into one unit, reducing the equipment footprint and pipeline layout complexity compared to existing decentralized processing equipment; each mechanism adopts a modular design; it facilitates later maintenance and component replacement, reducing equipment operation and maintenance costs.

[0038] Specifically, the two sixth motors 821 provide power to the two sets of grinding structures, driving the third rotating shaft 822 to rotate. The third rotating shaft 822, as the core of power transmission, drives the outer circular plate 823 to rotate on one hand, and drives the first sprocket 825 to rotate synchronously on the other hand. The circular plate 823 is used to install the grinding disc 824, and its rotation trajectory is adapted to the included angle area of ​​the vertical curved panel. The grinding disc 824 performs chamfering treatment on the weld edge by rotating, avoiding stress concentration and adapting to the lightweight and high-strength design of electric vehicle components. The first sprocket 825 transmits power to the second sprocket 827 through the chain 826. The chain 826 is a closed transmission component to ensure stable power transmission between the first sprocket 825 and the second sprocket 827.

A fourth rotating shaft 8210 is fixedly connected to the rear end of the baffle 828 near the middle. The cam 8211 is rotatably connected to the outer side of the fourth rotating shaft 8210. A connecting rod 8212 is rotatably connected to the rear end of the fourth rotating shaft 8210. The upper end of the connecting frame 8213 is fixedly connected to the mounting block 819. A return spring 8216 is provided on the outer side of the fourth rotating shaft 8210.

A fourth electric push rod 8215 is provided below the second rotating plate 8214 on the inner side of the connecting frame 8213.

[0040] Specifically, baffle 828 connects the second sprocket 827 and slide bar 829, transmitting the rotational power of the second sprocket 827 to slide bar 829; slide bar 829 rotates with baffle 828, causing cam 8211 to rotate synchronously; fourth rotating shaft 8210 provides mounting support for cam 8211 and can slide along its own axis, working with return spring 8216 to achieve reciprocating deflection of cam 8211; cam 8211 cleans weld slag and spatter from the weld surface by rotation and evenly applies flux around the weld, improving welding quality; fixed rod 8212 is fixedly connected to cam 8211 and, under the constraint of second rotating plate 8214, drives cam 8211 to rotate. The reciprocating deflection motion; the connecting frame 8213 provides installation support for components such as the fourth rotating shaft 8210 and the second rotating plate 8214, ensuring coordinated movement between the grinding assembly 82 and the mounting block 819; the second rotating plate 8214 provides a motion constraint surface for the fixed rod 8212 through its own angle adjustment, guiding the deflection trajectory of the cam 8211; the fourth electric push rod 8215 is used to push the second rotating plate 8214 to a suitable angle to adapt to different weld cleaning needs; one end of the return spring 8216 is slidably connected to the cam 8211, and the other end is fixedly connected to the baffle 828, using elasticity to keep the fixed rod 8212 always in contact with the second rotating plate 8214, ensuring stable movement of the cam 8211.

[0041] Working principle: During use, a loading robotic arm assembles the horizontal and vertical curved panels of the electric vehicle front shoe. The mounting holes of the horizontal curved panel and the protrusions of the vertical curved panel are precisely fitted together through a groove structure, and the whole assembly is placed above the assembly table 71. Four first electric push rods 72 extend simultaneously to initially position the horizontal and vertical curved panels of the two sets of front shoes, ensuring a unified assembly benchmark. The second electric push rod 73 is activated, and its output shaft drives the arc-shaped clamping plate 74 to move centripetally through an L-shaped rod. The inner wall rubber clips achieve flexible clamping of the vertical curved panel. The rubber clips can adapt to the arc tolerance of the vertical curved panel, ensuring uniform gap between the welding surfaces of the horizontal and vertical curved panels, and adapting to the low-stress clamping requirements of the lightweight materials of the electric vehicle front shoe. At this time, the inner cavity groove of the arc-shaped clamping plate 74 provides a motion trajectory for the pre-welding pretreatment: the second motor 77 is started synchronously, driving the first rotating shaft 78 to rotate. On the one hand, the seventh gear 79 meshes with the arc-shaped rack 75, driving the sliding bracket 76 to move along the arc-shaped trajectory to fit the workpiece; on the other hand, the eighth gear 710 meshes with the ninth gear 711, driving the grinding shaft 712 to rotate at high speed, removing the oxide layer and roughening the surface of the transverse curved panel outer wall. This treatment is suitable for high-strength aluminum alloy or low-alloy steel materials commonly used in electric vehicles, and can effectively improve the welding and assembly effect. Upon entering the welding process, the third electric actuator 813 is activated to push the adjustment frame 814 out, and the fourth motor 815 drives the opposing threaded rod 816 to rotate, so that the two moving blocks 817 adjust the distance synchronously to ensure that the welding head 9 is precisely aligned with the weld seam of the horizontal and vertical curved panel, and the upper and lower double weld seams are welded synchronously to adapt to the symmetrical structure of electric vehicle components. The third motor 811 is activated, and the welding assembly 81 is driven to make a circular motion through the support rod 812, so that the welding head 9 continuously welds along the weld seam trajectory. Simultaneously, the fifth motor 8111 is activated, driving the second rotating shaft 8112 to rotate. On one hand, the flux in the flux tank 8113 is stirred by the stirring blade 8114, and on the other hand, the flux is atomized and sprayed onto the weld seam through the atomizing nozzle 8110, improving the corrosion resistance and thermal stability of the weld seam of the electric vehicle component. The second rotating shaft 8112 drives the first rotating plate 8118 to rotate, and the connecting rod 8119 periodically engages with two sets of teeth in the moving frame 8117, causing the moving frame 8117 to drive the sliding plate 8116 to slide back and forth on the inner side of the support plate 8115, thereby pushing the mounting block 819 to drive the welding head 9 to perform high-frequency reciprocating motion. This action causes the weld seam to form a fish-scale shape, significantly enhancing the fatigue resistance of the front horseshoe weld seam of the electric vehicle and coping with the high-frequency impact load of the braking system. The elastic buffer structure of the spring limit rod 818 can compensate for the slight displacement error caused by thermal deformation during the welding process in real time, ensuring the consistency of the weld seam formation. Simultaneously, the sixth motor 821 is activated, and the third rotating shaft 822 drives the circular plate 823 to rotate. The front grinding disc 824 of the circular plate vertically fits into the corner area of ​​the curved panel to complete the chamfering process, avoiding stress concentration and adapting to the lightweight and high-strength design of electric vehicle components. The third rotating shaft 822 drives the first sprocket 825 to rotate, which is transmitted to the second sprocket 827 through the chain 826, driving the baffle 828, slide rod 829 and fourth rotating shaft 8210 to rotate synchronously. The two slide rods 829 drive the cam 8211 to rotate, and the fixing rod 8212 is located at the fourth electric push rod 821. Under the constraint of the second rotating plate 8214, the fixed rod 8212 is always in contact with the surface of the rotating plate: when the fixed rod 8212 approaches the second rotating plate 8214, the fourth rotating shaft 8210 slides and presses the return spring 8216; when it moves away, the elastic force of the return spring 8216 keeps the fixed rod 8212 in contact. During this process, the cam 8211 cleans the slag and spatter on the weld surface and evenly applies flux around the weld, further improving the welding quality; the connecting frame 8213 provides stable support for the grinding assembly 82, ensuring coordinated movement with the mounting block 819; After welding is completed, the welding assembly 81 and grinding assembly 82 are reset, and the first motor 4 is started to drive the first gear 51 to rotate. The first gear 51 drives multiple third gears 53 to rotate, the third gears 53 drive the universal joint 54 to rotate, the universal joint 54 drives the drill bit 55 to rotate, the first gear 51 drives the second gear 52 to rotate, the second gear 52 drives the fourth gear 58 to rotate, and the fourth gear 58 drives the fifth gear 59 to rotate at high speed. The fifth gear 59 drives the sixth gear 510 to rotate, and the sixth gear 510 drives the first threaded rod 511 to rotate. The first threaded rod 511 then drives the mounting box 3 to move downward along the fixed bracket 2 through the thread, so that the drill bit 55 drills holes in the transverse curved panel of the front shoe. The slide rail 56 is adjusted to match the drilling position along the slide frame 57, and the drill bit 55 processes the assembly holes in the transverse curved panel to meet the precise assembly requirements of the electric vehicle braking system. After processing is completed, the first motor 4 reverses to reset the drilling mechanism 5, and the electric turntable 6 drives the next set of clamping mechanisms 7 to flow to the processing position, realizing multi-station automated cycle.
