Description

Technical Field

[0001] This utility model belongs to the field of chip removal technology for CNC machine tools, and in particular relates to an automatic chip removal device for a turning and milling composite CNC machine tool. Background Technology

[0002] A turning-milling composite CNC machine tool is a composite machining equipment that integrates the functions of a lathe and a milling machine. It can perform multiple processes (such as turning, milling, drilling, tapping, etc.) in one setup, significantly improving machining efficiency and accuracy.

[0003] Traditional milling and turning CNC machine tools often leave a lot of debris on the bottom shell after use. The debris is usually collected in drawers. When the debris needs to be cleaned, the operator has to manually pull out the drawer and deal with the debris inside. When a lot of debris overflows from the drawer, a lot of debris will fall directly into the coolant tank at the bottom after the drawer is pulled out. This not only requires the operator to clean the coolant tank frequently, but also affects the use of coolant when there is too much debris. Utility Model Content

[0004] The purpose of this invention is to provide an automatic chip removal device for a milling and turning composite CNC machine tool. Specifically, by setting up a chip removal section, a starting motor drives a turntable to rotate clockwise, causing the spiral conveyor blades to transport chips from the discharge box to the discharge pipe. Continuous conveying automatically discharges the chips. A second starting motor drives a rotating roller, which continuously collides with an arc-shaped collision block, generating vibration. This vibration causes the bottom shell to vibrate, discharging residual chips from the bottom shell into the discharge box, thereby increasing the bottom shell's emptying rate and reducing chip residue. This solves the problem in existing milling and turning composite CNC machine tools where manual removal of the drawer is required, and when there are many chips in the drawer, a large amount of chips fall directly into the bottom coolant tank.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

When the starting motor 214 drives the turntable 215 to rotate clockwise, the spiral conveyor blade 216 will convey the debris in the discharge box 21 to the discharge pipe 211. The debris will be automatically discharged through continuous conveying. When the starting motor 222 drives the rotating roller 22 to rotate, several spherical collision blocks 242 will continuously collide with the arc-shaped collision block 23, thereby producing a vibration effect.

Several unblocking rods 33 are fixedly connected to the surface of the rotating rod 31. The front of the rotating rod 31 penetrates the bottom shell 1 and extends to the outside. The rotating rod 31 is rotatably connected to the bottom shell 1, and the front of the rotating rod 31 is connected to the transmission assembly 25.

During the rotation of the roller 22, the connecting rod 251 drives the disc 252 to rotate together. This causes the connecting rod 253 to drive the push-pull rod 254 to move up and down reciprocally. At this time, the other end of the push-pull rod 254 drives the rotating rod 31 to rotate reciprocally. The unblocking rod 33 moves by flipping up and down, which can move the material from the discharge box 21... The debris is cleared to prevent blockages and ensure proper discharge.

[0039] One specific application of this embodiment is:

[0040] After use, the chips produced by the milling and turning machine fall onto the bottom shell 1 and are guided into the discharge box 21 by the bottom shell 1. The trough 212 filters the coolant in the chips, allowing the coolant to flow smoothly into the coolant tank and intercepting the chips. When the chips need to be cleaned, the motor 214 drives the turntable 215 to rotate clockwise, and the spiral conveyor blade 216 conveys the chips in the discharge box 21 to the discharge pipe 211. Through continuous conveying, the chips are automatically discharged. During the chip discharge process, the motor 222 drives the roller 22 to rotate. The spherical collision block 242 will come into contact with the arc-shaped collision block 23 through rotation and collide with it. After the two come into contact, the spherical collision block 242 will be pushed into the inner groove 241. At this time, the spherical collision block 242 slides on the limit rod 243 and squeezes the spring 244, so the spherical collision block 242 will smoothly leave the arc-shaped collision block 23. Through continuous rotation, Then, several spherical collision blocks 242 will continuously collide with the arc-shaped collision block 23, thereby producing a vibration effect. At this time, the bottom shell 1 will vibrate, thereby discharging the residual debris on the bottom shell 1 into the discharge box 21, thus improving the unloading rate of the bottom shell 1 and reducing the residue of debris. In addition, during the rotation of the roller 22, it will drive the disc 252 to rotate together through the connecting rod 251. Then, the fixed shaft 255 on the disc 252 will pull the connecting rod 253 to move. The push-pull rod 254 is driven to move up and down reciprocally by the fixed shaft 255 on the push-pull rod 254. At this time, the other end of the push-pull rod 254 will drive the rotating rod 31 to rotate reciprocally, and the unblocking rod 33 will move together. The unblocking rod 33 moves by flipping up and down, and the flipping angle is small, so it will not contact the screw conveyor blade 216. By flipping the unblocking rod 33, the debris on the discharge box 21 can be unblocked to avoid blockage and affect the discharge of debris.
