CROSS-REFERENCE TO RELATED APPLICATIONS

This application is filed based upon and claims priority to Chinese Patent Application No. 201710442613.4, filed on Jun. 13, 2017, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to a detection device, specifically to a wheel center hole size qualification detection device.

BACKGROUND

The center hole of a wheel is directly matched with a main shaft of an automobile, so the size of the center hole is always strictly controlled in the machining process of the wheel; in the traditional control method, a worker holds a go-no go gauge to detect the size completely; however, since the automatic production mode is continually improved, this detection mode cannot adapt to modern production anymore; and therefore, an automatic detection device is needed to meet the full automatic online detection requirement of the key size.

SUMMARY

The present disclosure is aimed at providing a wheel center hole detection device capable of automatically detecting the size of a center hole of a wheel on line.

A wheel center hole size qualification detection device includes an upper cross beam, large guide posts, small guide posts, a central go-no go gauge no go end, a central go-no go gauge go end, small guide sleeves, large guide sleeves, a frame, clamping jaws, small cylinders, a connecting flange A, a connecting flange B, a lower cross beam, bases, a large cylinder, a central positioning pin, a mobile sensor support, a mobile sensor, a detection connecting rod, a shim plate, connecting bolts and a fixing plate.

The upper ends of the large guide posts are connected with the upper cross beam, the lower ends of the large guide posts are connected with the lower cross beam, the frame is fixed on a foundation via the bases, the large guide posts are arranged in the large guide sleeves on the frame, the large cylinder is fixed on the foundation and connected with the lower cross beam, the large cylinder drives an overall framework formed by the upper cross beam, the lower cross beam and the large guide posts to move up and down, the small guide posts are respectively fixed on two sides of the center of the upper cross beam and inside the large guide posts, the small cylinders are fixed below the frame, and the clamping jaws are connected with the small cylinders. The connecting flange B is fixedly connected with the connecting flange A, and a piston rod of the large cylinder11-1moves up and down to drive the flange A10-1and the central positioning pin12to move up and down.

The mobile sensor support13is fixed on the frame8. The mobile sensor14is fixed on the mobile sensor support13, the detection connecting rod15is fixed on the left large guide post2, the central go-no go gauge4is fixed in the fixing plate18, and the fixing plate18is connected with the shim plate16via the connecting bolts17. The shim plate16is fixed below the upper cross beam1.

In practical use, the piston rod of the cylinder ascends and drives the overall framework formed by the upper cross beam, the lower cross beam and the large guide posts to move up; after a robot clamps a wheel and positions the center hole of the wheel in the central positioning pin, the piston rod of the cylinder descends under the action of compressed air, and the small cylinders drive the clamping jaws to clamp the wheel. The piston rod of the cylinder descends and drives the overall framework formed by the upper cross beam, the lower cross beam and the large guide posts to move down, and after the central positioning pin is driven to fall, a cone head of the central go-no go gauge go end enters the center hole of the wheel first, then the central go-no go gauge go end enters the center hole of the wheel, and the central go-no go gauge no go end enters the center hole of the wheel, in which the whole process is controlled by a PLC (Programmable Logic Controller), and a display only displays qualification or disqualification. When the go-no go gauge go end passes through the center hole of the wheel, that is, arrives at the depth set by a computer program, the mobile sensor transmits a signal to a computer to judge that the go end of the center hole of the wheel is qualified; otherwise, it is judged as unqualified, and indicates that the center hole of the wheel is relatively small. When the go-no go gauge no go end passes through the center hole of the wheel, that is, arrives at the depth set by the computer program, the mobile sensor transmits a signal to the computer to judge that the no go end of the center hole of the wheel is unqualified; otherwise, it is judged as qualified, and indicates that the center hole of the wheel is relatively large. The whole process is controlled by the PLC, qualification displayed on the display is set by the computer program only when both the go end and the no go end are qualified, and if one is unqualified, it is also displayed on the display that the go end is relatively small or the no go end is relatively large. That is, the center hole of the wheel is unqualified.

The device in use can meet the requirement of wheel center hole size qualification detection; a wheel is accurately positioned by the positioning pin and the double sets of left and right limiting guide posts and guide sleeves, and then clamped and tested, so that the device has the characteristics of practical structure, high measurement precision, high efficiency, high working safety and reliability and the like.

DETAILED DESCRIPTION

The details and working conditions of the specific device provided by the present disclosure will be illustrated in detail below in combination with the accompanying drawing.

A wheel center hole size qualification detection device includes an upper cross beam1, large guide posts2, small guide posts3, a central go-no go gauge no go end4, a central go-no go gauge go end5, small guide sleeves6, large guide sleeves7, a frame8, clamping jaws9, small cylinders10, a connecting flange A10-1, a connecting flange B10-2, a lower cross beam10-3, bases11, a large cylinder11-1, a central positioning pin12, a mobile sensor support13, a mobile sensor14, a detection connecting rod15, a shim plate16, connecting bolts17and a fixing plate18.

The mobile sensor14is fixed on the mobile sensor support13, the detection connecting rod15is fixed on the left large guide post2, the central go-no go gauge4is fixed in the fixing plate18, and the fixing plate18is connected with the shim plate16via the connecting bolts17. The shim plate16is fixed below the upper cross beam1.

In practical use, the piston rod of the cylinder11-1ascends and drives the overall framework formed by the upper cross beam1, the lower cross beam10-3and the large guide posts2to move up; and after a robot clamps a wheel and positions the center hole of the wheel in the central positioning pin12, the piston rod of the cylinder11-1descends under the action of compressed air, and the small cylinders10drive the clamping jaws9to clamp the wheel. The piston rod of the cylinder11-1descends and drives the overall framework formed by the upper cross beam1, the lower cross beam10-3and the large guide posts2to move down, and after the central positioning pin12is driven to fall, a cone head of the central go-no go gauge go end5enters the center hole of the wheel first, then the central go-no go gauge go end5enters the center hole of the wheel, and the central go-no go gauge no go end4enters the center hole of the wheel, in which the whole process is controlled by a PLC, and a display only displays qualification or disqualification. When the go-no go gauge go end5passes through the center hole of the wheel, that is, arrives at the depth set by a computer program, the mobile sensor14transmits a signal to a computer to judge that the go end of the center hole of the wheel is qualified; otherwise, it is judged as unqualified, and indicates that the center hole of the wheel is relatively small. When the go-no go gauge no go end4passes through the center hole of the wheel, that is, arrives at the depth set by the computer program, the mobile sensor14transmits a signal to the computer to judge that the no go end of the center hole of the wheel is unqualified; otherwise, it is judged as qualified, and indicates that the center hole of the wheel is relatively large. The whole process is controlled by the PLC, qualification displayed on the display is set by the computer program only when both the go end and the no go end are qualified, and if one is unqualified, it is also displayed on the display that the go end is relatively small or the no go end is relatively large. That is, the center hole of the wheel is unqualified.
