Description

Technical Field

[0001] This utility model belongs to the field of CNC machine tool technology, and more specifically, it relates to a tool-following negative pressure dust removal mechanical device for a five-axis double-swivel head. Background Technology

[0002] This device is a dynamic, locally sealed dust removal system installed on the double-swivel spindle of a five-axis machine tool. It forms a high-intensity local negative pressure zone near the cutting point (pollution source) through a negative pressure dust collection hood that is synchronized with the tool movement trajectory in real time, effectively capturing and removing dust and oil mist before they diffuse into the machine tool's machining chamber.

[0003] Based on existing technologies, it has been found that most of the suction heads used in the current technology are fixed covers or remote flexible hoses. In the case of double swing head operation, interference is prone to occur and it is impossible to ensure that the air inlet is always close to the cutting area. Moreover, collisions often cause damage or jamming of the suction head. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a blade-following negative pressure dust removal mechanical device for a five-axis double-swing head, which solves the problems in the prior art where the blade-following suction head is mostly a fixed cover or a remote flexible hose, which is prone to interference under double-swing head conditions and cannot ensure that the suction port is always close to the cutting area, and the suction head is often damaged or jammed when it collides.

[0005] This utility model discloses a five-axis double-swivel head-type blade-following negative pressure dust removal mechanical device, which is achieved by the following specific technical means: A mechanical device for a five-axis double-swivel head, comprising an upper flange; The upper flange is provided with a dust removal telescopic pipe at its bottom; the dust removal telescopic pipe is provided with a lower flange at its bottom; the lower flange is provided with a dust removal flexible chain at its bottom; the upper flange is provided with a guide sleeve; a guide rod is slidably provided inside the guide sleeve; a floating joint is provided at the bottom of the guide rod; a connector is provided at the bottom of the floating joint; the bottom of the connector is connected to the lower flange; cylinders are provided on both sides of the top of the upper flange; and a dust suction pipe is provided on the top of the upper flange.

[0006] Furthermore, the upper flange is provided with a circular hole through which the dust suction pipe passes; the guide sleeve is configured to cooperate with the guide rod; the guide rod is a cylindrical structure with a raised top.

[0007] Furthermore, four sets of guide rods are provided; the guide rods are located on both sides of the cylinder; the bottom of the cylinder is connected to the floating joint.

[0008] Furthermore, the suction pipe is connected to a vacuum cleaner via a pipe.

[0009] Furthermore, the dust removal flexible chain is arranged around the lower flange.

[0010] Furthermore, a main shaft is provided on the upper flange; a double-swing head is provided at the bottom of the main shaft; a control motor is provided on the side of the double-swing head; a cutting tool is provided on the output shaft of the control motor; and the control motor is concentrically arranged with the main shaft.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This device is equipped with cylinders. Two sets of cylinders are controlled by a back-end control device to extend and retract synchronously, thereby moving the lower flange downward and stretching the dust removal telescopic tube to accommodate tools of different lengths. The connection between the upper flange, the dust removal telescopic tube, and the lower flange ensures that the negative pressure airflow channel remains sealed and unobstructed when the double swing head rotates at any angle. The dust suction pipe and dust removal soft chain form a full-round wrap around the tool, which better improves the dust removal effect and does not affect the normal use of the tool. The dust suction port is close to the tool tip, which efficiently removes dust from the source, significantly improving the capture rate. There is no motion interference. The follow-up design ensures that the dust removal device does not occupy the processing space and does not affect the normal movement of the machine tool. At the same time, the floating joint and connecting parts are passively approached to the cutting area in multiple positions and have collision self-protection capabilities.

This ensures that the negative pressure airflow channel remains sealed and unobstructed when the double-swivel head 10 rotates at any angle; the dust removal soft chain 4 provides all-around coverage for the tool 12, further improving dust removal efficiency; the guide sleeve 101 is used for sliding connection to the guide rod 5, and the floating joint 6 cooperates with the connector 601, achieving universal compensation through the universal ball joint of the connector 601, and passively approaching the cutting area in multiple positions while possessing collision self-protection capability; the cylinder 7 consists of a telescopic sleeve with an inner tube diameter of approximately 20 mm. The outer tube has a maximum outer diameter of approximately 35 mm and an effective axial extension stroke of approximately 0–100, 0–150, and 0–250 mm. Positioning is ensured by using cylinder 7, floating joint 6, and dust removal telescopic tube 2. The synchronous operation of the two sets of cylinders 7 relies on position sensors to detect the actual position of the piston rod in real time. The PLC compares the position feedback of the two cylinders 7. If a deviation occurs, the flow rate into each cylinder 7 is adjusted by controlling the proportional valve to eliminate the deviation. This is a conventional control method adopted in this field.

[0022] Among them, such as Figure 2 As shown, the dust removal flexible chain 4 is arranged around the lower flange 3.

[0023] Among them, such as Figure 2As shown, a main shaft 9 is provided on the upper flange 1; a double sway head component 10 is provided at the bottom of the main shaft 9; a control motor 11 is provided on the side of the double sway head component 10; a cutter 12 is provided on the output shaft of the control motor 11; the control motor 11 is concentrically arranged with the main shaft 9; the main shaft 9 is used to drive the rotation by an external motor, while the double sway head component 10 is driven by the motor to drive the control motor 11 to rotate, thereby achieving the swaying effect. The control motor 11 is used to control the rotation of the cutter 12. These are all conventional technical means in the field and are not considered as innovative points. The cutter 12 can be replaced as needed.

[0024] The specific usage and function of this embodiment are as follows: In this invention, when using the device, the two sets of cylinders 7 are synchronously extended and retracted by the background control device, thereby driving the lower flange 3 to move downward and stretching the dust removal telescopic tube 2 to accommodate cutters 12 of different lengths. The connection between the upper flange 1, the dust removal telescopic tube 2, and the lower flange 3 ensures that the negative pressure airflow channel remains sealed and unobstructed when the double swing head 10 rotates at any angle. The dust suction pipe 8 and the dust removal soft chain 4 form a full-round wrap around the cutter 12, which better improves the dust removal effect and does not affect the normal use of the cutter 12. The dust extraction port is located close to the cutting edge, efficiently removing dust from the source and significantly improving the capture rate. There is no motion interference, and the follow-up design ensures that the dust removal device does not occupy the processing space or affect the normal movement of the machine tool. The floating joint 6 and the connecting piece 601 are also provided. The universal ball joint of the connecting piece 601 can achieve the effect of universal compensation. It can passively approach the cutting area in multiple positions and has the ability to protect itself from collision. The external of the dust extraction pipe 8 is connected to the vacuum cleaner.
