Description

Co-operating cutter mechanism of belt drive spindle

The present invention belongs to a co-moving tooling mechanism of a belt-type transmission spindle, and specifically refers to a co-operating knife-making mechanism that utilizes a belt-type transmission spindle machining center, and is driven by a loose-clamping 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.

The creator of this new type is engaged in the machining structure of the machining center machine and its phase After years of knowing its advantages and disadvantages, the company is committed to improving its shortcomings. It makes the structure of the knife more practical and meets the needs of users. After years of trial improvement, the new type of belt-driven spindle is finally created. Knife mechanism.

Therefore, the main purpose of the present invention is to provide a co-moving tooling mechanism for a belt-type transmission spindle, which can be used for the co-moving tool-making mechanism of the spindle machining center, and the process of swapping the tool on the spindle with the tool in the tool magazine. In the middle, the action of the press knife, the loose knife and the knife change can be performed simultaneously. The same action tool of the belt drive spindle is driven by the loose clamp cam, so that the pressure roller presses the main shaft. When the tool change arm is pressed down by the pressure wheel, the tool of the tool on the spindle is loosely clamped and the tool change is performed synchronously, so that the tool changer can perform the tool change between the tool on the tool cover and the tool on the spindle to complete the tool change to improve the machining. The center uses the working efficiency of the machine when changing the tool. The belt-driven main shaft of the belt-driven spindle has the function of manually controlling the loose-clamping knife. When the tool magazine or the tool change arm mechanism is damaged, or the tool magazine is not needed When the knife is changed, the cylinder can be manually controlled to drive the pressure roller of the same action cutter mechanism to press the spindle to perform the spindle loose clamping knife and tool change.
