Description

Technical Field

[0001] This utility model belongs to the field of CNC machine tools, and specifically relates to a high-precision CNC machine tool that can automatically clean up waste chips. Background Technology

[0002] In traditional CNC machining of sheet metal, the accumulation of waste chips in the machining area can interfere with the normal movement of the machining tools, leading to a decrease in machining accuracy. Furthermore, in order to reduce the accumulation of waste chips, frequent machine stops are required to clean them, which increases downtime, reduces machine tool utilization, and slows down machining speed.

[0003] Meanwhile, chip entrapment into the cutting tool or cutting head will accelerate tool wear, greatly shorten tool life, and further increase maintenance costs; chip entrapment will also lead to a decline in machining quality, uneven cutting force, and defects such as vibration marks and ripples on the machined surface; the machined surface may have scratches, pits, etc., affecting the appearance and performance of the parts, and even causing the parts to be scrapped.

[0004] Therefore, the above problems urgently need to be solved. Utility Model Content

[0005] Purpose of the utility model: To overcome the above shortcomings, the purpose of this utility model is to provide a high-precision CNC machine tool that can automatically clean up waste chips. By setting several chip blowing ports on the placement tray, and cooperating with chip blowing air valves, the need for automatic cleaning of waste chips during the processing is realized, preventing waste chips from affecting processing production; the unloading air valve, together with the material picking air groove and the blowing port, facilitates the removal of the processed sheet metal; at the same time, the drive components of the X, Y, and Z axes, together with several limiting parts, realize high-precision processing and improve production efficiency.

[0006] Technical Solution: To achieve the above objectives, this utility model provides a high-precision CNC machine tool capable of automatically cleaning up waste chips, including a base, an X-axis drive assembly, a placement tray, a Y-axis drive assembly, and a Z-axis drive assembly. The X-axis drive assembly is mounted on the base; the placement tray is mounted on the X-axis drive assembly; a feeding air valve and a chip blowing air valve are located below the placement tray; several chip blowing ports are also provided on one side of the upper end of the placement tray; several ventilation grooves are provided inside the placement tray, and the chip blowing ports and chip blowing air valves are connected through the ventilation grooves; a set of Y-axis drive mounting plates are provided on the base; a Y-axis drive assembly is located between the Y-axis drive mounting plates; and a Z-axis drive assembly is located on the Y-axis drive assembly. The chip blowing air valve and chip blowing ports on the placement tray can effectively blow away the waste chips generated during the machining process from the machining area, keeping the machining area clean, improving machining accuracy, reducing wear on the cutting tools caused by waste chips, extending the tool life, and reducing production costs; at the same time, the X, Y, and Z-axis drive assembly setup ensures high precision during the machining process.

[0007] Furthermore, the upper surface of the placement tray is provided with a material-retrieving air groove; the material-retrieving air groove is provided with a blowing port corresponding to the material-discharging air valve. By setting a blowing port corresponding to the material-discharging air valve, semi-automatic blowing operation can be realized; after processing is completed, the air valve controls the blowing port to blow out gas, blowing up one side of the processed board, which is convenient for material retrieval and improves production efficiency.

[0008] Furthermore, the X-axis drive assembly includes an X-axis motor, a set of X-axis guide columns, several tray connecting blocks, an X-axis screw, and an X-axis guide block. The X-axis motor is located on one side of the base; the X-axis guide columns are located between the bases; the tray connecting blocks are located on the X-axis guide columns and connected to the lower surface of the tray; the X-axis screw is located between the bases and between the X-axis guide columns; one end of the X-axis screw is connected to the output end of the X-axis motor; and the X-axis guide block is located on the lower surface of the tray and threadedly connected to the X-axis screw. The X-axis guide columns provide stable guidance for the movement of the tray, making its movement in the X-axis direction smoother and more accurate. During processing, this ensures that the tray moves along a predetermined trajectory, avoiding a decrease in processing accuracy due to shaking or offset, and ensuring processing quality.

[0009] Furthermore, the Y-axis drive assembly includes a Y-axis motor, a set of Y-axis guide posts, a Z-axis drive mounting bracket, and a Y-axis screw. The Y-axis motor is located on one side of the Y-axis drive mounting plate. The Y-axis guide posts and the Y-axis screw are located between the Y-axis drive mounting plate. One end of the Y-axis screw is connected to the output end of the Y-axis motor. The Z-axis drive mounting bracket is mounted on the Y-axis guide posts and threadedly connected to the Y-axis screw. The connection between the Y-axis screw and the output end of the Y-axis motor, and the threaded connection between the Z-axis drive mounting bracket and the Y-axis screw, enables precise drive of the Z-axis drive mounting bracket by the Y-axis motor. Through the transmission of the screw and thread, the position of the Z-axis drive mounting bracket in the Y-axis direction can be precisely controlled, improving the processing accuracy and adaptability of the equipment.

[0010] Furthermore, the Z-axis drive assembly includes a Z-axis motor, a set of Z-axis guide posts, a tool mounting bracket, and a Z-axis screw. The Z-axis motor is positioned above the Z-axis drive mounting bracket. The Z-axis guide posts and Z-axis screw are located between the upper and lower ends of the Z-axis drive mounting bracket, with the Z-axis screw connected to the output end of the Z-axis motor. The tool mounting bracket is mounted on the Z-axis guide posts and threadedly connected to the Z-axis screw. The design of the tool mounting bracket facilitates tool installation and replacement; operators can quickly install tools onto the tool mounting bracket or easily replace tools when needed, improving production efficiency, reducing downtime, and adapting to the tool requirements of different machining tasks.

[0011] Furthermore, a set of Y-axis limit sensors is provided on one side of the Y-axis drive mounting plate; a corresponding Y-axis limit pin is provided on the Z-axis drive mounting bracket. The cooperation between the Y-axis limit sensors and the Y-axis limit pins enables precise positioning of the Z-axis drive mounting bracket in the Y-axis direction; when the Z-axis drive mounting bracket moves to the set limit position, the Y-axis limit pin triggers the Y-axis limit sensors, sending a signal to stop the Y-axis drive assembly, thereby preventing the Z-axis drive mounting bracket from exceeding the allowable movement range and preventing equipment damage or processing errors caused by excessive movement.

[0012] Furthermore, a Z-axis limiting pin is provided on one side of the cutter head mounting bracket; a set of Z-axis limiting sensors corresponding to the Z-axis limiting pin are also provided on the Z-axis drive mounting bracket. During equipment operation, even in the event of an accident or operational error, the Z-axis limiting sensors and Z-axis limiting pins can function promptly, preventing collisions or damage to the cutter head mounting bracket through precise limiting control, thus protecting the safety of the equipment and operators.

[0043] Specifically, the Z-axis motor 61 and Z-axis screw 64 can be replaced with a linear motor as an option. The tool head mounting bracket 63 is directly mounted on the mover of the linear motor.

The photoelectric limit switch has a fast response speed and can stop the movement of the tool head mounting bracket 63 in time, avoiding excessive downward movement and damage to the tool head.
