A method for detecting the center depth of aluminum wheel billet

Abstract

The invention relates to a device and method for detecting the depth of the wheel center of an aluminum wheel slab. The device includes a roller tray (1), a position sensor (3), a frame (4), a CCD camera (5), a programmable control Device (6) and laser ranging sensor (7), upper servo cylinder (8), motor support (11), servo motor (12), lower servo cylinder (13). The benefits of the present invention are that, using the method of automatic detection and identification of wheel core depth of wheel billets to identify and classify wheel billets, reduce the influence of large casting size tolerances on machining size tolerances, improve the machining yield of automatic machining units, and ensure The production line runs automatically with quality and quantity guaranteed, while reducing the labor intensity of the operator.

Description

technical field [0001] The invention relates to the field of industrial detection, in particular to a device and a method for detecting the depth of a wheel center of an aluminum wheel slab. Background technique [0002] With the increase of labor costs, the low-pressure casting aluminum wheel industry has more and more urgent requirements for automatic production. The production process of low-pressure casting aluminum wheels is: melting → low-pressure casting → degating → heat treatment → machining → painting → packaging and shipping. Since the casting tolerance of the casting wheel rough is generally ±0.9mm, and there is a certain degree of randomness, while the size of the cap groove of the finished wheel is guaranteed by the casting surface and the processing surface, and the tolerance requirements are strict, generally ±0.25mm, if directly The cast wheel blank after heat treatment is transported to the automatic machining unit by the logistics roller table for processi...

Since the casting tolerance of the casting wheel rough is generally ±0.9mm, and there is a certain degree of randomness, while the size of the cap groove of the finished wheel is guaranteed by the casting surface and the processing surface, and the tolerance requirements are strict, generally ±0.25mm, if directly The cast wheel blank after heat treatment is transported to the automatic machining unit by the logistics roller table for processing. Due to the randomness of the cast blank size within the tolerance range, the cap groove size guaranteed by the casting surface and the machining surface is out of tolerance. The finished product rate of the wheel machining is low, resulting in an increase in cost
