A centralized chip removal device for multiple machine tools

Abstract

The present invention discloses a centralized chip removal device for multiple machine tools, which belongs to the field of mechanical technology. A chip conveyor is arranged on both sides of each machine tool, and a chip trolley is placed under the chip conveyor. The chip trolley is located on a fixed platform designed with a roller conveyor. A push-pull oil cylinder is arranged behind the chip trolley, and a chip trolley conveying mechanism is arranged in front of the fixed platform. The mechanism comprises a fixed frame, a conveying roller, a chain sprocket, a motor, a trolley positioning device, a trolley guide device, a switch, a control system, etc. When the chips are fully collected, the push-pull oil cylinder pushes the chip trolley away from the fixed platform. When leaving, the switch receives a signal and the chip conveyor stops working. When the chip trolley is pushed onto the conveying mechanism, the switch on the conveying mechanism senses the chip trolley, sends a signal, and the motor rotates, driving the conveying roller to rotate through the chain sprocket, thereby transmitting the chip trolley to the outside of the factory. At this time, the push-pull oil cylinder is always in an extended state and is pulled back after the trolley returns.
