Abstract

The purpose of the invention is to provide a belt transmission main shaft of synchronous tool exchange mechanism capable of synchronously executing tool unclamping motions of tool holding-down, clasping, loosening and clamping during the process of interchanging tool on the main shaft and the tool inside the tool magazine. Since the belt transmission main shaft of synchronous tool exchange mechanism is driven by the loosen clamping cam, the pressure roller downwardly presses the main shaft so when the tool changer arm downwardly presses the main shaft, the motions of tool loosening and unclamping on the main shaft is synchronously executed to allow the tool unclamping arm to perform exchange for the tool of the main shaft and the tool of the sheath so as to complete tool change. It could enhance the working efficiency of the mechanical machining center during tool change. The belt transmission main shaft of synchronous tool exchange mechanism has manual control tool clamping function. When the tool magazine or the tool changer arm mechanism is damaged or the tool magazine is not required to select tool or change tool, the cylinder motion can be manually controlled to drive the pressure roller of the synchronous tool exchange mechanism downwardly pressures the main shaft to perform motions of main shaft's loosening and clamping.

Description

Co-operating cutter mechanism of belt drive spindle

The invention belongs to a co-moving knife-making mechanism of a belt-type transmission main shaft, in particular to a co-moving knife-making mechanism using a belt-type transmission spindle machining center, which is driven by a loose-clamping knife cam to cause the pressing wheel to press the main shaft. When the tool change arm is pressed down by the pressure wheel, the tool for loosening the knife on the spindle and the knife changer are synchronously executed, so that the tool changer can perform the tool change between the tool on the tool cover and the tool on the spindle. Improve the working efficiency of the machining center of the belt-type drive spindle with the tool during tool change, and have the function of manually controlling the loose-clamping tool. When the tool magazine or the tool change arm mechanism is damaged, or when the tool change is not required. The cylinder can be manually controlled to drive the pressure roller of the same action cutter mechanism to press the spindle to perform the action of loosening the cutter and changing the cutter.

Conventionally, the existing belt-type drive spindle machining center mechanical cutter mechanism is equipped with a cutter cylinder connected to the electric control device on the spindle seat, and the motor drives the camshaft and the arm mounted on the cam box through the transmission device. The same movement, the rotation and axial movement of the spindle of the tool arm can realize the tool change action. At present, the action of the belt machining center is controlled by the cam box driving the signal sprocket through the sprocket chain. The disadvantage is that it is changing. When the knife arm is used to fasten the knife sleeve and the spindle, it must stop waiting for the spindle to loosen the knife. The system receives the signal wheel and the cutter cylinder performs the spindle loosening, which causes the movement of the knife, the loose knife and the knife to be not smooth. Stable and with security concerns.
