A rotating arm 53 is installed at the end of the output shaft of the rotating table 52, and tool grabbing assemblies are installed at both ends of the rotating arm 53. In the present invention, when the conveying mechanism 6 transfers the tool holder mechanism 7 carrying the required tool to the position directly below the tool grabbing assembly, the electric push rod 51 drives the rotating table 52, the rotating arm 53 and the tool grabbing assembly to move downward. The tool grabbing assembly is sleeved on the end of the tool handle and clamped to pull the tool out of the tool holder mechanism 7, and relies on the rotating table 52 to drive the rotating arm 53 and the tool grabbing assembly to rotate, thereby completing the conversion operation of the new and old tools.

[0036] As a further solution in the present invention, the tool grabbing assembly includes an annular grabbing seat 54, and a plurality of torsion spring shafts 56 are installed at the bottom edge of the annular grabbing seat 54, an L-shaped structured clamping member 57 is installed at the output shaft end of the torsion spring shaft 56, and an annular electromagnet 55 is installed at the upper end of the annular grabbing seat 54, and the annular electromagnet 55 is sleeved on the outer position of the clamping member 57. In the present invention, when the tool grabbing assembly is close to the tool handle, the tool handle squeezes the clamping member 57 to move inward, and under the action of the torsion spring shaft 56, the raised parts of the plurality of clamping members 57 are embedded in the groove of the tool handle. When the tool grabbing assembly lifts the tool upward, the gathered clamping members 57 form a trumpet-shaped claw structure, which self-locks and grabs the tool handle. When it needs to be separated from the tool, the annular electromagnet 55 receives an electrical signal, and the magnetic attraction drives the clamping member 57 to expand and loosen the tool handle, completing the separation operation of the tool grabbing assembly and the tool handle, thereby improving the stability of the tool grabbing.

[0037] As a further solution in the present invention, the tool magazine support 17 includes an annular bracket 171 fixedly connected to the rotating shaft 15, and a plurality of annularly distributed transverse connecting arms 172 are arranged above the annular bracket 171, and an angle rotation motor 173 is installed on the side of the transverse connecting arm 172.

In the present invention, when the sealing member 196 is separated from the exhaust groove 194, a large amount of air directly enters the seat body 1 from the wind tube 191 to blow away the impurities in the seat body 1, and during the blowing process, the sealing member 196 is driven by the push rod motor 195 to alternately rise and fall, and a regular pulse airflow is generated in the rectangular blowing groove 192, thereby improving the blowing efficiency of the surface of the tool head and accelerating the moving speed of the impurities in the seat body 1.

[0041] As a further solution in the present invention, the cleaning mechanism 13 includes two guide tubes 131 connected to the base body 1, and the ends of the two guide tubes 131 are installed with L-shaped deposition tubes 132, a separator 133 is installed between the two deposition tubes 132, and an exhaust fan 134 is installed at the upper end of the separator 133. In the present invention, debris is sucked into the deposition tube 132 through the guide tube 131, and impurities such as oil foam are deposited in the deposition tube 132 and flow into the separator 133 for filtration, so that the debris and oil foam are filtered and separated, which is convenient for centralized processing of debris and purification of the operating environment of the CNC machine tool.

[0042] When in use, the tool is inserted into the tool holder mechanism 7, and when the conveying mechanism 6 is in a vertical state, the tools are stored in the tool magazine cover 14, which effectively avoids the influence of the machine tool processing environment on the tools, and multiple chain-type tool magazines are stored vertically by rotation, which effectively increases the number of tools stored in the tool magazine. Secondly, when the tool needs to be changed, the tool magazine bracket 17 rotates the conveying mechanism 6 carrying the new tool to the movable door mechanism 11.
