[0032] In order to further understand the utility model content, characteristics and effects of the present application, the following examples are given, and the drawings are described in detail as follows:

[0033] The embodiment of the present application provides a tool changing spindle with a cleaning channel, such asFigures 1-5 As shown, it comprises: an outer shell 1, an inner shell 2 and a pull rod 3 for grabbing the tool 100, the inner shell 2 is arranged in the outer shell 1, the inner shell 2 is configured with a containing chamber 21 for placing the tool 100; a first cavity 11 is formed between the middle part of the outer shell 1 and the middle part of the inner shell 2, an air inlet hole 12 is arranged on the outer shell 1, the air inlet hole 12 is communicated with the first cavity 11, a first channel 22 is arranged on the inner shell 2, the first channel 22 communicates the containing chamber 21 with the first cavity 11.

[0034] It should be noted that the tool changing spindle of the present technical solution is connected with the air pump through the air inlet hole 12, the air pump is an external device for providing air source, the pressure of the air source is selected according to the requirement, and the air pump is directly obtained from the prior art, so the structure thereof is not specifically described in the present application.

[0035] In some embodiments, referring to Figures 2-3 When the tool 100 is replaced, the tool 100 is pushed out of the containing chamber 21, the containing chamber 21 is in a non-sealed state, and the dust after processing can enter the tool changing spindle through the containing chamber 21; at this time, the air source provides gas, so that the gas enters the first cavity 11 from the air inlet hole 12, enters the containing chamber 21 through the first channel 22, thereby cleaning the dust out of the containing chamber 21, avoiding the dust remaining in the containing chamber 21, and ensuring that the containing chamber 21 is clean.

[0036] In some embodiments, referring to Figures 4-6 A second cavity 13 is formed between the bottom of the outer shell 1 and the bottom of the inner shell 2, a bearing 4 is arranged between the bottom of the inner shell 2 and the bottom of the outer shell 1, and the inner shell 2 and the outer shell 1 are rotatably connected through the bearing 4; the bearing 4 is located in the second cavity 13. A second channel 23 is further arranged on the inner shell 2, and the second channel 23 communicates the first channel 22 with the second cavity 13.

[0037] Further, due to the inevitable gap between the mechanical parts, there is a gap between the bearing 4 and the second cavity 13, and the dust can enter the second cavity 13 through the gap; during the cutting operation, the containing chamber 21 is installed with the tool 100, and the containing chamber 21 is in a sealed state; at this time, the gas enters the first channel 22 from the first cavity 11, enters the second cavity 13 through the second channel 23, thereby cleaning the dust in the second cavity 13 out of the tool changing spindle, and at the same time, the dust is prevented from entering the bearing 4, so that the inner shell 2 and the outer shell 1 are abnormally rotated, and the machining precision is reduced.

[0038] In some embodiments, referring to Figures 3-6The first cavity 11 and the second cavity 13 are provided with baffles 14. The baffles 14 are fixedly connected with or integrally formed with the inner wall of the shell 1. The baffles 14 have a gap with the outer wall of the inner shell 2, and the gas in the first cavity 11 enters the second cavity 13 through the gap, thereby removing the dust in the second cavity 13 from the tool changing spindle, and the gap further cleans the second cavity 13, thereby ensuring the cleanliness of the bearing 4 in the second cavity 13.

[0039] In some embodiments, referring to Figure 4 and Figure 6 The number of the first channels 22 and the second channels 23 is multiple, preferably two. The first channels 22 are arranged in a horizontal direction, and the second channels 23 are arranged at an inclined angle relative to the first channels 22. When the containing chamber 21 is in an unsealed state, the gas can more easily enter the containing chamber 21 from the first cavity 11 through the first channels 22 arranged in a horizontal direction.

[0040] Further, the cross-sectional area of the first channels 22 is larger than that of the second channels 23.

[0041] In some embodiments, referring to Figure 5 The pull rod 3 is arranged in the inner shell 2 and has a hollow structure. The pull rod 3 is provided with a sealing cover 31 and a sealing ring 32 between the pull rod 3 and the inner shell 2. The sealing ring 32 and the sealing cover 31 are arranged above the containing chamber 21, and the sealing ring 32 and the sealing cover 31 seal the upper end of the containing chamber 21, so that the gas can only be blown out from the lower part of the containing chamber 21, and the dust and gas are prevented from flowing into the pull rod 3 and the gap between the pull rod 3 and the inner shell 2.

[0042] The working principle of the tool changing spindle of the present embodiment is as follows:

[0043] When the tool changing spindle changes tools, the tool 100 is pushed out of the containing chamber 21. At this time, the containing chamber 21 is in an unsealed state, and the dust generated during machining enters the containing chamber 21. The gas enters the first cavity 11 from the gas inlet hole 12, enters the containing chamber 21 through the first channels 22, and removes the dust from the containing chamber 21. The dust is prevented from remaining in the containing chamber 21, the cleanliness of the containing chamber 21 is ensured, and the dust is prevented from affecting the high-speed operation of the tool changing spindle, thereby improving the machining quality.

[0044] When the main shaft of the technical scheme is in operation, the tool 100 is installed in the accommodating chamber 21, at this time, the accommodating chamber 21 is in a closed state, the gas enters the first channel 22 from the first cavity 11, then enters the second cavity 13 through the second channel 23, the dust in the second cavity 13 is removed, the dust is prevented from entering the bearing 4, the bearing 4 is kept clean and good operation, and therefore the service life of the tool changing main shaft is prolonged.

[0045] The above is only the embodiment of the present application and is not used to limit the present application. The present application can be variously changed and modified for those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the scope of the claims of the present application.
