This application is filed based upon and claims priority to Chinese Patent Application No. 201610442099.X, filed on Jun. 20, 2016, the entire contents of which are incorporated herein by reference.

BACKGROUND

As a wheel center bore directly matches with an automobile spindle in connection size, the size of the wheel center bore generally needs to be strictly controlled in a wheel machining production process. According to the traditional control method, an operator holds a go/no go gauge to perform 100% detection on the wheel center bore. However, by virtue of continuously improved automatic production mode, such detection mode obviously already cannot fit to modern production. Therefore, it needs an automatic detection device to achieve the full automation online detection requirement of the key size.

The small guide posts are fixed between the center of the upper crossbeam and the inner sides of the two-side large guide posts, the small air cylinders are fixed on the lower surface of the stand, and the jaws are connected with the small air cylinders. The centering pin A is fixed on the coupling flange A, and the coupling flange B is fixedly connected with the coupling flange A.

During actual use, a piston rod of the air cylinder moves upwards to drive the whole frame formed by the upper crossbeam, the lower crossbeam and the large guide posts to move upwards; a robot clamps a wheel and places a wheel center bore among the centering pins B to be located, and then the piston rod of the air cylinder moves downwards under the action of compressed air; the small air cylinders drive the jaws to clamp the wheel; the piston rod of the air cylinder moves downwards to drive the whole frame formed by the upper crossbeam, the lower crossbeam and the large guide posts to move downwards and also drive the centering pins B for the wheel to drop down; and after the centering pins B for the wheel drop down, a conical head of the center go/no go gauge go end, the center go/no go gauge go end and the center go/no go gauge no go end sequentially enter the wheel center bore, wherein the whole process is controlled by a programmable logic controller (PLC), and a display only displays that the size of the wheel center bore is qualified or not. When the center go/no go gauge go end passes through the wheel center bore, namely reaches a depth set by a program of a computer, the mobile sensor transmits a signal to the computer to judge that the size of the wheel center bore at the go end is qualified; otherwise, the size of the wheel center bore at the go end is not qualified and is relatively smaller. When the center go/no go gauge no go end passes through the wheel center bore, namely reaches another depth set by the program of the computer, the mobile sensor transmits a signal to the computer to judge that the size of the wheel center bore at the no go end is not qualified; otherwise, the size of the wheel center bore at the no go end is qualified, and is relatively larger. The whole process is controlled by the PLC, and the program of the computer sets: only when the size of the wheel center bore is qualified at the go end and the no go end, the display displays that the size of the wheel center bore is qualified; and if the size of the wheel center bore is not qualified at one of the go end and the no go end, the display displays that the size of the wheel center bore is relatively smaller at the go end or is relatively larger at the no go end, that is, the size of the wheel center bore is not qualified.

In use, the device can meet the requirement for detecting whether the size of the wheel center bore is qualified. The wheel is firstly located by the centering pins and then is clamped, and the size of the wheel center bore is detected. The wheel center bore is accurately located by limiting the left and right guide posts and guide sleeves. The device has the characteristics of practical structure, high detection accuracy, high efficiency, working safety and reliability and the like.
