Description

Technical Field

[0001] This utility model belongs to the field of machine tool processing technology, specifically a five-axis oscillating head with an internally integrated spindle follow-up dust collection pipe. Background Technology

[0002] The processing of composite materials (such as carbon fiber and fiberglass) generates a large amount of micron-sized dust. This dust not only damages the human respiratory system (such as causing pneumoconiosis), but also, conductive dust like carbon fiber, can potentially cause an explosion when it reaches a certain concentration in the air. Traditional machine tools use near-spindle dust collection to directly collect dust at its source (tool tip), reducing the proportion of dust that diffuses into the air. However, in traditional spindle dust collection methods, the dust collection pipe is mainly integrated outside the oscillating head. This approach has the following problems:

[0003] 1. Externally integrated dust suction pipes and collection rings may restrict toolpaths, especially when machining complex curved surfaces in five-axis machining, and are prone to collisions with workpieces or fixtures;

[0004] 2. The suction hose needs to move synchronously with the main shaft of the oscillating head. Long-term extension, contraction or twisting can easily lead to fatigue and cracking of the hose.

[0005] 3. If the external suction pipe is not made of anti-static material, the composite material dust is prone to generating static sparks due to friction in the high-speed airflow, which poses a risk of combustion and explosion.

[0006] In view of this, a five-axis oscillating head with an internally integrated spindle-driven suction pipe is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a five-axis oscillating head with an internally integrated main shaft-driven dust collection pipe in order to solve the problems mentioned above.

[0008] The technical solution adopted by this utility model is as follows: A five-axis oscillating head with an internally integrated spindle-driven dust collection pipe includes a fork-shaped bracket, a dust collection disc, and a spindle box. The fork-shaped bracket has a dust collection channel inside. The dust collection disc is fitted on the fork-shaped bracket and has a dust collection chamber that communicates with the dust collection channel. The spindle box is rotatably disposed in the fork-shaped bracket. A second dust collection disc that communicates with the dust collection chamber is provided on the side of the spindle box. The lower end of the second dust collection disc has a dust collection port that communicates with the outside.

[0009] In a preferred embodiment, an accordion cover is installed on the spindle housing at the outer end of the dust suction port.

[0010] In a preferred embodiment, a servo electric cylinder is provided inside the spindle box, and the output end of the servo electric cylinder extends out of the spindle box and is connected to the bellows cover.

[0011] In a preferred embodiment, the dust suction channels are two sets and symmetrically distributed within the fork-shaped bracket.

[0012] In a preferred embodiment, a suction pipe connected to the suction chamber is installed on the suction plate, and the suction pipe is connected to an external suction device.

[0013] In a preferred embodiment, the second dust collection disc is in two sets and is symmetrically distributed at both ends of the main shaft box.

[0014] In a preferred embodiment, the second suction disk has an annular suction chamber, and the end of the suction channel is located in the rotation trajectory of the second suction disk.

[0015] In a preferred embodiment, the accordion cover is a ring-shaped accordion cover.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effect of this utility model is: it facilitates better...

[0017] 1.

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0028] Reference Figure 1-5 A five-axis oscillating head with an internally integrated spindle-driven suction pipe includes a fork-shaped bracket 3, a suction disc 2, and a spindle box 4. The fork-shaped bracket 3 has a suction channel 31 inside. The suction disc 2 is mounted on the fork-shaped bracket 3 and has a suction chamber 21 connected to the suction channel 31. The spindle box 4 is rotatably mounted inside the fork-shaped bracket 3. A second suction disc 7 connected to the suction chamber 21 is located on the side of the spindle box 4. The lower end of the second suction disc 72 has a suction port 72 connected to the outside, integrating the suction pipe. Inside the five-axis oscillating head, a connected suction channel is formed by the suction channel 31, the suction disc 2, and the second suction disc 42. Compared with traditional external suction pipes, the internal suction pipe design can greatly reduce the rotation radius of the oscillating head assembly. This avoids the problem of the suction pipe interfering with tooling or workpieces when processing composite materials at special angles, and avoids the problem of pipe weathering, loosening, and falling off after long-term use. Moreover, the pipe material itself is the same as the material of the five-axis oscillating head, which can reduce the risk of static sparks generated by friction in high-speed airflow.

[0029] In this embodiment, refer to Figure 1 and Figure 2As shown, a bellows cover 6 is installed on the spindle box 4 at the outer end of the dust suction port 72. The bellows cover 6 is an annular bellows cover. A servo cylinder 5 is installed inside the spindle box 4. The output end of the servo cylinder 5 extends out of the spindle box 4 and is connected to the bellows cover 6. The annular bellows cover is controlled by the servo cylinder 5. The extension and retraction of the annular bellows cover can be controlled according to the length of the tool (not shown in the figure). In this way, the length of the dust suction cover 6 can be flexibly controlled according to actual use, and a good dust suction effect can still be maintained without interfering with the workpiece.

[0030] In this embodiment, refer to Figures 1-3 As shown, the dust collection channels 31 are arranged in two sets and symmetrically distributed within the fork-shaped bracket 3. The dust collection disc 2 is equipped with a dust collection pipe 1 that communicates with the dust collection chamber 21. The dust collection pipe 1 is connected to an external dust collection device (not shown in the figure). The second dust collection disc 42 is arranged in two sets and symmetrically distributed at both ends of the spindle box 4. When used on a machine tool, the external dust collection device generates suction. The waste generated during the machine tool processing enters the second dust collection disc 42 and the dust collection channel 31 sequentially through the dust collection ports 72 on both sides of the bellows cover 6. Then, it is discharged into the dust collection device through the dust collection pipe 1 on the dust collection disc 2, thus completing the dust collection operation. The two sets of dust collection ports 72 can realize the distribution of waste for dust collection, making it less prone to clogging.

[0031] The vacuuming equipment used is a vacuum cleaner with a hose or other vacuuming device, which will not be described in detail here.

[0032] In this embodiment, refer to Figure 3 and Figure 5 As shown, the second suction disk 42 has an annular suction chamber 71, and the end of the suction channel 31 is located in the rotation trajectory of the second suction disk 42. This design allows normal suction operation to be met even when the spindle box 4 rotates relative to the fork bracket 3.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
