[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] It should be noted that all directional indicators (such as up, down, left, right, front, back, upper end, lower end, top, bottom, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0030] See Figure 1-3 As shown, a dust collection device for a five-axis machining center includes a dust collection hood 1 connected to a retractable dust collection pipe 2. The dust collection pipe 2 is equipped with a cylinder 3 that can drive its extension and retraction, and a connecting rod 4 is also provided on the dust collection pipe 2. A fixed seat 5 is provided at the end of the connecting rod 4 away from the dust collection pipe 2. A front cover 6 is provided on the fixed seat 5, and the front cover 6 is detachably mounted on the fixed seat 5 to form a clamp.

[0031] Furthermore, the outer diameter of the dust hood 1 gradually decreases from top to bottom, forming a conical hood, and a sealing gasket 7 is provided at the upper end of the dust hood 1. The sealing gasket 7 is made of rubber.

[0032] Further, see Figure 5-6As shown, the suction pipe 2 consists of an outer pipe 21 and an inner pipe 22. The inner pipe 22 is L-shaped. The outer pipe 21 is slidably fitted onto the vertical connecting section of the inner pipe 22. A sealing ring 14 is provided between the vertical connecting section of the outer pipe 21 and the inner pipe 22. As the outer pipe 21 and the inner pipe 22 move together, i.e., they extend and retract, the sealing ring 14 can move synchronously with the inner pipe 22. In this embodiment, when installed, the suction hood 1 is connected to the horizontal connecting section of the inner pipe 22, and the other end of the connecting rod 4 is fixedly connected to the outer pipe 21.

[0033] Further, see Figure 3 As shown, the cylinder 3 is a guide rod cylinder, which is vertically and downwardly positioned between the connecting rod 4 and the outer tube 21 via a support 15. The piston rod of the guide rod cylinder is connected to the horizontal connecting section of the inner tube 22. The cylinder 3 can drive the inner tube 22 to move up and down, thereby realizing the extension and retraction of the suction pipe 2, which in turn drives the suction hood 1 to move up and down. In this embodiment, to prevent dust, debris, etc. from damaging the cylinder 3, a protective cover 8 is provided between the connecting rod 4 and the outer tube 21 to enclose the cylinder 3 body. The protective cover 8 is provided with a connector for connecting to an external air supply pipe, and the output port of the connector is connected to the cylinder 3.

[0034] Further, see Figure 1-3 As shown, the fixed base 5 and the front cover 6 are respectively provided with an integrally formed lug 9, and the lug 9 is provided with a locking hole through which the locking bolt 10 can pass. During installation, the fixed base 5 and the front cover 6 are locked together by the locking bolt 10 to form a clamp for locking onto the machine tool spindle. In this example, the inner surfaces of the fixed base 5 and the front cover 6 are respectively provided with a gasket 13. The gasket 13 prevents the fixed base 5 and the front cover 6 from directly scratching the surface of the machine tool spindle, thereby protecting the machine tool spindle and reducing wear. At the same time, the gasket 13 ensures the tightness and stability of the connection between the fixed base 5 and the front cover 6 and the machine tool spindle, preventing loosening or even falling off due to vibration or other factors during use, which could damage the machine tool.

[0035] Furthermore, in another embodiment, see [link to another embodiment]. Figure 4As shown, one end of the front cover 6 is hinged to one end of the fixed base 5, and a movable rod 11 is hinged to the other end of the fixed base 5. The movable rod 11 is provided with a fastening nut 12, and a U-shaped groove 61 adapted to the movable rod 11 is opened at the other end of the front cover 6. Gaskets 13 are also provided on the inner surfaces of the fixed base 5 and the front cover 6 respectively. During installation, the front cover 6 is connected to the fixed base 5 by inserting the movable rod 11 into the U-shaped groove 61 opened at its other end and tightening the fastening nut 12.

[0036] The working principle of this utility model is as follows:

[0037] See Figure 7-8 As shown in the figure (label B represents the machine tool spindle; label C represents the tool holder; label D represents the cutting tool; label E represents this device); before use, first ensure that there are no cutting tools on the machine tool spindle, then fix this device to the machine tool spindle through the fixing seat 5 and the front cover 6; then connect the external air supply pipe to the connector on the protective cover 8, and connect the external pipe 21 to the external dust collection device.

[0038] In use, firstly, the piston rod of cylinder 3 extends, driving the dust collection hood 1 downward by driving the inner tube 22; then the machine tool tool changing system installs the tool onto the machine tool spindle, and after the installation is completed, the piston rod of cylinder 3 retracts, causing the dust collection hood 1 to move upward and reset. At this time, the sealing gasket 7 at the upper end of the dust collection hood 1 abuts against the plane at the lower end of the spindle, while covering the exposed part of the tool holder, but the tool extends out from the lower end of the dust collection hood 1, and a gap is maintained between the inner surface of the dust collection hood 1 and the tool holder and the tool.

[0039] During cutting, this device moves with the spindle. At the same time, under the action of the external dust collection device, dust and debris generated during cutting enter the dust collection hood 1 through the gap between the inner surface of the dust collection hood 1 and the tool. Then, it is sucked into the external dust collection device through the dust collection pipe 2. This ensures that dust and debris are cleaned up in a timely manner during the processing, thereby preventing dust and debris generated during cutting from flying around, maintaining a clean processing environment, reducing pollution and wear on machine tool parts, improving processing accuracy and machine tool service life, and enhancing the comfort and safety of the working environment.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
