## Abstract

Disclosed is a wheel flange detection device. A positioning column and a linear guide rail are mounted on a flange plate, a connecting plate is connected with the linear guide rail via a guide rail sliding seat, a shaft sleeve is fixed on the connecting plate, and a dial indicator is fixed on the shaft sleeve via a lock sleeve; the upper side wall of the shaft sleeve is a conical surface, and is matched with an inner hole conical surface of the lock sleeve; threads are formed in the middle of the side wall of the shaft sleeve and matched with threads of the inner hole of the lock sleeve; 12 groups of vertical slots are formed in the upper side wall of the shaft sleeve.

## Claims

### Claim 1

A wheel flange detection device, comprising a positioning column, a flange plate, a linear guide rail, a guide rail sliding seat, a connecting plate, a shaft sleeve, a lock sleeve and a dial indicator, wherein the positioning column and the linear guide rail are mounted on the flange plate, the connecting plate is connected with the linear guide rail via the guide rail sliding seat, the shaft sleeve is fixed on the connecting plate, and the dial indicator is fixed on the shaft sleeve via the lock sleeve.

### Claim 2 (depends on 1)

The wheel flange detection device of claim 1, wherein the upper side wall of the shaft sleeve is a conical surface, and the conical surface is matched with an inner hole conical surface of the lock sleeve.

### Claim 3 (depends on 1)

The wheel flange detection device of claim 1, wherein threads are formed in the middle of the side wall of the shaft sleeve and the threads are matched with threads of the inner hole of the lock sleeve.

### Claim 4 (depends on 1)

The wheel flange detection device of claim 1, wherein 12 groups of vertical slots are formed in the upper side wall of the shaft sleeve; and when the lock sleeve locks the dial indicator, the lock sleeve moves down relatively to the shaft sleeve via threaded fit between the shaft sleeve, and the lock sleeve, the conical surface of the lock sleeve extrudes the conical surface of the shaft sleeve, and the inner hole at the vertical slots of the shaft sleeve contracts to lock the dial indicator.
