Wheel blank outer rim scribing device
A wheel blank outer rim scribing device is composed of a wheel positioning and clamping system, an upper auxiliary system, a lower auxiliary system, a rim scribing system and a vision detection system. The wheel positioning and clamping system completes positioning of a wheel on a roller bed, clamping and rotating drive; the upper auxiliary system improves the axial positioning precision and power assisting rotation of the wheel; the lower auxiliary system improves the radial positioning precision and power assisting rotation of the wheel; the rim scribing system completes groove ridge machining of the outer rim of the wheel; and the vision detection system detects blanks having insufficient outer rim machining allowance. The device not only can scribe ridges on the outer rim of the wheel, but also can check the blanks having insufficient outer rim machining allowance.
1. A wheel blank outer rim scribing device, being composed of a frame, an adjusting guide rail, an adjusting cylinder, a left sliding table, a right sliding table, a first gear rack, a left cylinder, a right cylinder, a first guide post, a lifting table, a roll shaft support, a roll shaft, a roller, a driven wheel, a servo motor, a driving wheel, a clamping cylinder, a clamping guide rail, a left sliding plate, a right sliding plate, a second gear rack, drive motors, clamping wheels, a side cylinder, a side guide rail, a side lifting table, a first feeding cylinder, a first support plate, first guide rails, a first sliding block, electric cylinders, a tool apron, a scribing tool, a second feeding cylinder, a second support plate, second guide rails, a second sliding block, a vision sensor, upper cylinders, second guide posts, a feeding platform, an upper servo motor, a shaft, a rotating disk and a pressure plate, wherein the first feeding cylinder is fixed on the side of the first support plate, the output end of the first feeding cylinder being connected with the first sliding block, the first sliding block being mounted on the first guide rails, the three electric cylinders being fixed on the first sliding block at equal intervals from top to bottom, the output ends of the electric cylinder being connected with the tool apron, the scribing tool being mounted on the tool apron, the tool apron being matched with a built-in slide of the first sliding block, the electric cylinders driving the tool apron to slide left and right to adjust the telescopic length of the scribing tool, and the nose radius of the scribing tool being R3.
2. The wheel blank outer rim scribing device according to claim 1 , wherein the second support plate is fixed on the left of the frame, the two second guide rails are mounted on the bottom plane of the second support plate, the second feeding cylinder is fixed on the side of the second support plate, the output end of the second feeding cylinder is connected with the second sliding block, the second sliding block is mounted on the second guide rails, and the vision sensor is mounted at the front end of the second sliding block; when whether groove ridges of a rim are continuous is detected, the vision sensor can be driven by the second feeding cylinder to approach the rim of the wheel to improve the recognition precision.
