Problems solved by technology

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

Embodiment 1

[0018] Book figure 1 Shown: the wheel casting slab (2) is transferred to the roller tray (1), the CCD camera (5) installed on the frame (4) is activated, the image of the wheel casting slab (2) is collected, and output to the programmable The controller (6), the programmable controller (6) performs image recognition on the obtained pictures, recognizes the position of the nearest bolt hole counterbore on the wheel casting blank from the X axis, and places the bolt hole counterbore on the bottom plane of the bolt hole counterbore. Take any point as the wheel center measurement point (10), and calculate the angle between the wheel center measurement point (10) and the X axis, calculate the angle difference, and output the signal to the servo motor (12) to drive the roller table ( 1) Rotate, align the wheel center measuring point (10) on the wheel billet (2) on the X-axis, and transmit the aligned X-axis position of the wheel center measuring point (10) to the programmable contro...

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...
