Furthermore, the synchronous wheel set mechanism comprises a small wheel, a large wheel, a synchronous belt and a supporting shaft, one end of the supporting shaft is welded at the center of the bottom of the fixing frame, the other end of the supporting shaft penetrates through the connecting plate to be connected with the crank connecting rod mechanism, the large wheel penetrates through the supporting shaft, and the small wheel is driven by the motor to drive the large wheel to rotate through the synchronous belt.

Further, the crank link mechanism comprises a crank and two connecting rods, the two connecting rods are mutually embedded and self-locked, the crank penetrates through the supporting shaft and is fixed to the top end of the supporting shaft, one end of each of the two connecting rods is connected with the crank, and the other end of each of the two connecting rods is fixed to the guide rail assembly.

Further, the guide rail assembly comprises a guide rail, a sliding block and a guide rail support, the guide rail support is in threaded connection with the U-shaped structure side vertical surface at the upper end of the fixing frame, the sliding block is fixed at the upper end of the guide rail support, one end of the guide rail is connected with a crank of the crank-link mechanism, and the other end of the guide rail slides linearly on the sliding block.

Furthermore, the motor is in threaded connection with the connecting plate and is in self-locking connection with the middle hole of the small wheel of the synchronous wheel set.

The beneficial effect of this application lies in: to the condition that the automatic track module needs the centering in laying process, the wing rib through hole track laying automatic centering device that this application provided can automatically regulated track avris and wing rib through hole side elevation clearance and precision, guarantees that the track can not appear the skew, drop, the non-automation condition of laying etc. In order to make the sliding stroke as large as possible, two extreme positions of the sliding block are required as the initial position of the centering mechanism and the position when the two arms are fully extended, but in this case, the two connecting rods interfere at the initial position, so that the two connecting rods are designed into an embedded structure. Another advantage of this configuration is that the initial position can be easily determined, which is the initial position when the two links are self-locking into each other.

The present application is described in further detail below with reference to the accompanying drawings and examples.
