Description

Technical Field

[0001] This utility model relates to the field of CNC equipment technology, and in particular to a CNC equipment for manufacturing a four-sided rotating shaft. Background Technology

[0002] A square shaft is a mechanical structure typically used to transmit motion or force. In some machines or equipment, a square shaft can provide stable support and rotation. During the manufacturing process of a square shaft, CNC equipment is required to cut and mill metal steel materials, and the milling process of the CNC equipment generates a large amount of milling debris.

[0003] A self-cleaning CNC machine (authorization announcement number: CN215543034U) is available. It achieves high-speed airflow by starting a blower and adjusting the duct with a rotating mechanism to achieve reciprocating deflection. This ensures that the high-speed airflow thoroughly cleans the inside of the CNC machine. By using the high-speed airflow to blow away residual debris inside the CNC machine, the debris is finally discharged from the chip discharge port of the CNC machine with the airflow, thus completing the automatic cleaning process inside the main body of the CNC machine.

[0004] However, this type of CNC equipment has some shortcomings in actual use: because the position of the guide tube is fixed and the rotation of the guide tube is adjusted only by the rotating mechanism, the angle range of the high-speed airflow ejected by the guide tube is limited, and it cannot achieve thorough cleaning of residual debris inside the CNC equipment; therefore, we propose a four-sided rotating shaft manufacturing CNC equipment to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a four-sided rotary shaft manufacturing CNC equipment to solve the aforementioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A CNC machine for manufacturing four-sided rotary shafts includes a CNC machine body. A machining chamber is formed within the CNC machine body.

A mounting groove is formed on the inner wall of the track slider, and a rack is movably installed in the mounting groove. The rack meshes with the gear. A deflection angle adjustment drive mechanism for the rack is provided on the inner wall of the track slider. A common air collection pipe is fixedly installed on the ends of the two connecting rods that are close to each other.

The other end of the threaded rod is threaded through the track slider and rotatably installed on the inner wall of one side of the track groove. Through the translation drive mechanism, the air collection pipe can be moved horizontally, further improving the angle range of the high-speed airflow ejected by the air collection pipe.

[0010] Preferably, the deflection angle adjustment drive mechanism includes a side block, a fixed block, and an electric push rod. The side block is fixedly installed on one side of the rack, the fixed block is fixedly installed on the inner wall of the track slider, the electric push rod is fixedly installed on one side of the fixed block, and the output end of the electric push rod is fixedly installed on one side of the side block. Through the deflection angle adjustment drive mechanism, the reciprocating deflection angle of the air collection pipe is adjusted, thereby improving the injection angle range of the high-speed airflow.

[0011] Preferably, the multiple high-speed airflow nozzles on the bottom side of the air collection pipe are arranged in a circumferential array; the high-speed airflow is sprayed through the multiple high-speed airflow nozzles into the machining chamber of the CNC equipment body to achieve the blowing and cleaning treatment of residual debris generated during the manufacturing of the four-sided rotating shaft in the machining chamber.

[0012] Preferably, the jetting mechanism includes a blower and a jetting hose. The blower is provided on the top side of the CNC equipment body. One end of the jetting hose is connected to the blowing end of the blower, and the other end of the jetting hose is connected to the air collecting pipe. By starting the blower, a high-speed airflow is delivered into the air collecting pipe through the jetting hose.

[0013] Preferably, one end of a guide rod is fixedly installed on the inner wall of one side of the track groove corresponding to the track frame, and the other end of the guide rod passes through the outside of the track slider and is fixedly installed on the inner wall of the other side of the track groove; the guide rod is used to limit and guide the track slider.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This four-axis rotary shaft manufacturing CNC equipment, by starting a blower, delivers high-speed airflow into the air collection pipe through a jet hose. The high-speed airflow is then sprayed into the machining chamber of the CNC equipment body through multiple high-speed airflow nozzles. Through two sets of deflection angle adjustment drive mechanisms, the deflection angle of the air collection pipe is adjusted reciprocally, thereby increasing the range of high-speed airflow injection angle. At the same time, with the cooperation of the translation drive mechanism, the range of high-speed airflow injection angle in the air collection pipe is further increased, achieving thorough blowing and cleaning of residual debris generated during the manufacturing of the four-axis rotary shaft inside the CNC equipment.

An adjustment drive mechanism for the deflection angle of the rack 11 is provided on the inner wall of the track slider 5. A common air collection pipe 15 is fixedly installed at the ends of the two connecting rods 8 that are close to each other. Multiple high-speed airflow nozzles 16 are provided on the bottom side of the air collection pipe 15. An air jet mechanism for the air collection pipe 15 is provided on the top side of the CNC equipment body 1.

[0025] Furthermore, the cross-section of the track groove 4 inside the track frame 3 is convex, the track slider 5 is adapted to the track groove 4, and a groove is provided on one side of the track slider 5; this facilitates the sliding of the track slider 5 within the track groove 4.

[0026] Specifically, the translation drive mechanism includes a motor 6 and a threaded rod 7. The motor 6 is fixedly installed on one side of the track frame 3, and one end of the threaded rod 7 is fixedly installed at the output end of the motor 6. The other end of the threaded rod 7 is threaded through the track slider 5 and rotatably installed on the inner wall of one side of the track groove 4. Through the translation drive mechanism, the air collection pipe 15 can be moved horizontally, further improving the angle range of the high-speed airflow ejected by the air collection pipe 15.

[0027] Furthermore, the deflection angle adjustment drive mechanism includes a side block 12, a fixed block 13, and an electric push rod 14. The side block 12 is fixedly installed on one side of the rack 11, the fixed block 13 is fixedly installed on the inner wall of the track slider 5, the electric push rod 14 is fixedly installed on one side of the fixed block 13, and the output end of the electric push rod 14 is fixedly installed on one side of the side block 12. Through the deflection angle adjustment drive mechanism, the reciprocating deflection angle adjustment of the air collection pipe 15 is realized, thereby improving the injection angle range of the high-speed airflow.

[0028] Furthermore, multiple high-speed airflow nozzles 16 on the bottom side of the air collection pipe 15 are arranged in a circumferential array; the high-speed airflow is sprayed into the machining chamber 2 of the CNC equipment body 1 through the multiple high-speed airflow nozzles 16, so as to blow away and clean the residual debris generated during the manufacturing of the square rotating shaft in the machining chamber 2.

[0029] Specifically, the jet mechanism includes a blower 17 and a jet hose 18. The blower 17 is installed on the top side of the CNC equipment body 1. One end of the jet hose 18 is connected to the blowing end of the blower 17, and the other end of the jet hose 18 is connected to the air collection pipe 15.

[0031] In use: When using the CNC machine body 1 to mill and manufacture a square rotating shaft, a large amount of milling debris is generated during the milling process. When it is necessary to clean the milling debris remaining inside the machining chamber 2 of the CNC machine body 1, the blower 17 is started, and a high-speed airflow is delivered to the air collection pipe 15 through the air jet hose 18. The high-speed airflow is sprayed into the machining chamber 2 of the CNC machine body 1 through multiple high-speed air jet nozzles 16. At the same time, by driving two electric push rods 14, two racks 11 are synchronously pushed to move in the corresponding mounting slots 10. Since the two sets of racks 11 mesh with the corresponding gears 9, thus... The two sets of gears 9 and connecting rods 8 are driven to rotate synchronously, thereby realizing the reciprocating deflection angle adjustment of the air collection pipe 15 and improving the injection angle range of the high-speed airflow. At the same time, by starting the motor 6, the threaded rod 7 is rotated, thereby synchronously driving the two track sliders 5 to move in the track grooves 4 in the corresponding track frames 3, thereby realizing the horizontal position adjustment of the air collection pipe 15. In conjunction with the two sets of deflection angle adjustment drive mechanisms, the angle range of the high-speed airflow injected by the air collection pipe 15 is further improved, and the residual debris generated during the manufacturing of the square rotating shaft inside the CNC equipment is thoroughly blown and cleaned.
