Description

Technical Field

[0001] This utility model relates to the technical field of machining and drilling of automobile wheels, specifically a flexible production line for machining valve holes in automobile wheels. Background Technology

[0002] Wheels are crucial components of a car chassis, serving not only as aesthetic parts but also as safety devices. The valve bore is a vital structure on the wheel, primarily housing the valve stem. Traditional manufacturing processes utilize machining centers for single-sequence drilling. However, with continuous advancements in wheel manufacturing technology, the industry is evolving towards intelligent, integrated, flexible, and automated mixed-line production. Based on this trend, this patent leverages process innovation to drive equipment innovation, providing a flexible production line for processing wheel valve bores. This line enables centralized, mixed-line automated production of wheel valve bores, resulting in higher efficiency, lower costs, a novel structure, and strong versatility, offering a new solution for improving efficiency and reducing costs in wheel processing. Summary of the Invention

[0003] The purpose of this utility model is to provide a flexible production line for processing wheel valve holes, which can centrally and automatically produce wheel valve holes, and can simultaneously and efficiently process four sizes of wheels. It adopts a dual-spindle symmetrical process layout, which is both highly efficient and saves floor space. The production line has a novel structure and strong versatility.

[0004] To achieve the above objectives, the technical solution of this utility model is: a flexible production line for processing wheel valve holes, comprising an inlet roller conveyor, sensors, a robot, a first station, a second station, a third station, a fourth station, a first drilling assembly, a second drilling assembly, an outlet roller conveyor, an X-axis servo motor, an X-axis ball screw, an X-axis guide rail, an X-axis slide, a Y-axis servo motor, a Y-axis guide rail, a Y-axis ball screw, a Y-axis slide, a Z-axis motor, a Z-axis guide rail, a Z-axis slide, a first spindle, and a second spindle. It mainly includes an automatic wheel positioning and transportation system, a four-station fixture system, and a dual-spindle drilling system.

[0005] The automatic wheel positioning and transportation system includes an infeed roller conveyor, sensors, robots, and an outfeed roller conveyor. Wheels are fed into the infeed roller conveyor, positioned and size-sorted by sensors, and then transferred by a robot to a size-matching fixture for drilling. Finally, the robot clamps the wheel and transfers it to the outfeed roller conveyor for unloading.

[0006] The four-station clamping system comprises four stations: Station 1, Station 2, Station 3, and Station 4. These stations are located between the inlet and outlet roller conveyors, arranged in a rectangular quadrant. Station 1, located at the top left, consists of a servo-motor driven flip-plate, with wheel clamps mounted on it, capable of positioning and clamping 17-inch wheels. Station 2, located at the top right, consists of a servo-motor driven flip-plate, with wheel clamps mounted on it, capable of positioning and clamping 18-inch wheels. Station 3, located at the bottom left, consists of a servo-motor driven flip-plate, with wheel clamps mounted on it, capable of positioning and clamping 19-inch wheels. Station 4, located at the bottom right, consists of a servo-motor driven flip-plate, with wheel clamps mounted on it, capable of positioning and clamping 20-inch wheels. These four stations can independently position and clamp wheels ranging from 17 to 20 inches, thus solving the positioning and clamping problem when materials arrive on mixed production lines.

[0007] The dual-spindle drilling system comprises a first drilling assembly, a second drilling assembly, an X-axis servo motor, an X-axis ball screw, an X-axis guide rail, an X-axis slide, a Y-axis servo motor, a Y-axis guide rail, a Y-axis ball screw, a Y-axis slide, a Z-axis motor, a Z-axis guide rail, a Z-axis slide, a first spindle, and a second spindle. The first and second drilling assemblies are symmetrically arranged on both sides of the four-station fixture system. The two drilling assemblies have identical structures, both being three-axis servo modules. The X-axis servo motor controls the movement of the X-axis slide. The Y-axis servo motor is mounted on the X-axis slide, and its output is connected to the Y-axis slide, controlling its movement. The Z-axis servo motor is mounted on the Y-axis slide, and its output is connected to the Z-axis slide, controlling its movement. The first spindle is mounted on the Z-axis slide, and a valve hole drill bit is mounted on the first spindle. The first spindle can drill valve holes for the wheels at the first and second workstations, while the second spindle can drill valve holes for the wheels at the third and fourth workstations. This dual-spindle drilling system can operate independently and in parallel without interfering with each other, greatly improving production efficiency.

[0008] The working process of a flexible production line for processing wheel valve holes is as follows: First, the wheels are fed into the wheel feed roller conveyor. Then, the wheels are positioned and sorted by sensors to identify their size. Then, a robot transports the wheels to the corresponding size station. The spindle is driven by a three-axis servo module to drill holes. Finally, the robot picks up the wheels and transfers them to the wheel output roller conveyor for unloading.
