Detailed Description
In order to better understand the purpose, structure and function of the present invention, the roller axle connecting and locking structure of the turnover plate of the bedding-in press machine according to the present invention will be described in further detail with reference to fig. 2.
Referring to fig. 2, the II-roller shaft connection locking structure of the turnover plate roller of the bedding-in press machine is characterized in that a II 17 roller is arranged on a II 19 guide rail of the bedding-in press machine, a transmission shaft II 15 is arranged in the II 17 roller, the II 17 roller and the II 15 transmission shaft are connected through a II 18 bearing, the extending end of the II 15 transmission shaft is connected with a II 10 turnover plate main body, the II 17 roller rotates to drive the II 10 turnover plate main body to move, and finally, the process turnover function is achieved.
II 15 of transmission shaft in the running roller II 17 and II 18 of bearing pass through II 18 internal diameters of transition fit connection bearing, and II 17 of running roller are close to II 10 one sides of returning face plate main part and are equipped with the shaft shoulder, and II outsides of bearing are equipped with II 16 retaining rings of bearing, and II 18 axial positioning of bearing pass through the shaft shoulder of II 17 of running roller and II 16 fixes of II 18 outside bearing retaining rings of bearing, and II 18 external diameters of bearing pass through transition fit and are connected with II 17 of running roller.
The end part of the II 10 main body of the turnover plate is provided with an installation sleeve 14 matched with the extending end of the II 15 transmission shaft, the II 15 transmission shaft is installed in the installation sleeve 14, the II 15 transmission shaft is provided with a shaft shoulder, one end of the installation sleeve 14 is close to the II 17 roller, the other end of the installation sleeve is slightly shorter than the end part of the II 15 transmission shaft, the II 15 transmission shaft and the installation sleeve 14 are connected through an expansion sleeve 11, the expansion sleeve 11 is fixed through the shaft shoulder of the II 15 transmission shaft, and the expansion sleeve 11 can be selected according to the transmitted torque and the received axial force. The double-cone expansion sleeve is adopted in the embodiment, so that a large torque can be borne, and the requirement of overturning the overturning plate main body II is met.
A central hole is formed in the central shaft of the transmission shaft II 15, a counter bore is formed in the central hole at the outer side end of the transmission shaft II and used for containing the end portion of a connecting bolt, the connecting bolt penetrates through the central hole and extends out of the transmission shaft II, an end cover II 13 is arranged at the end portion of the connecting bolt, and the roller II 17 is connected with the end cover II 13 through the connecting bolt II and a nut II 12.
