[0002] When a machine tool processes complex workpieces, it is often necessary to replace different tools according to the processing requirements to achieve different processing effects. In order to facilitate the replacement of tools, most of the current CNC machine tools are equipped with a tool magazine. The tool magazine will be equipped with several fixtures for installing tools. The required tools are installed on the tool magazine in advance. When the machine tool spindle needs to replace the tool, the original tool is placed on the empty fixture, and then the tool magazine adjusts the required tool to the machine tool spindle for installation. However, before changing the tool, there may be residual chips on the tool in use. After being brought into the tool magazine, long-term accumulation will cause the tool magazine to run poorly. During processing, cutting chips are also easy to enter the interior from the tool change port. This requires regular disassembly and cleaning of the tool magazine, which is very troublesome.

[0030] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0031] For example, see the attached Figure 1 The present invention provides a CNC machine tool with a tool changing and chip blowing device, including a machine tool base 100, a machine tool column 200 is fixedly arranged on the upper end of the machine tool base 100, and the machine tool column 200 is driven and connected to the machine tool spindle 300. The machine tool spindle 300 is a prior art. The machine tool spindle 300 is provided with a spindle head capable of clamping a tool, and the spindle head can be raised and lowered under the drive of a lifting drive device such as a linear motor. The machine tool base 100 is provided with a transverse sliding rail, and the transverse sliding rail is connected to a transverse slide 500. The transverse slide 500 is provided with a longitudinal sliding rail, and the longitudinal sliding rail is connected to a workbench 600 for mounting and fixing a workpiece. The transverse slide 500 can slide transversely under the drive of the drive device, and the workbench 600 can slide longitudinally under the drive of the drive device; the machine tool column 200 is also provided with a tool magazine module 400, as shown in the attached figure. Figure 2As shown, the tool magazine module 400 includes a tool magazine fixing plate 410, which is rotatably arranged on the machine tool column 200. At the same time, the tool magazine fixing plate 410 can rotate at an angle under the drive of a servo motor or other device. The tool magazine fixing plate 410 is rotatably provided with a tool clamp fixing plate 420. The tool clamp fixing plate 420 is provided with a plurality of elastic tool clamps 430 in an annular manner on one side away from the tool magazine fixing plate 410. The elastic tool clamp 430 is detachably fixedly connected to a universal tool handle 440, as shown in the attached figure. Figure 3 As shown, the elastic tool clamp 430 includes two elastic clamping claws 431 that can be elastically reset, and the end of the elastic clamping claw 431 is rotatably provided with a tool handle limiting wheel 432, and the side wall of the universal tool handle 440 is provided with a tool handle mounting groove 441 that is adapted to the tool handle limiting wheel 432. The tool handle limiting wheel 432 is clamped into the tool handle mounting groove 441 to realize the detachable connection between the universal tool handle 440 and the elastic tool clamp 430, and the tool magazine fixed plate 410 is fixedly connected to the tool magazine dust cover 450, and the elastic tool clamp 430 is arranged between the tool magazine fixed plate 410 and the tool magazine dust cover 450, and the tool magazine dust cover 450 is provided with a tool changing port. The clamping plate 420 can rotate any elastic tool clamp 430 to the tool changing port under the drive of a servo motor or other device, and then the spindle head of the machine tool spindle 300 can perform the tool changing operation at the tool changing port. At the same time, the CNC machine tool is also provided with a blowing device 460. The blowing device 460 includes a high-pressure air pipe 461 connected to the air source. The high-pressure air pipe 461 supplies air through an external air source. The high-pressure air pipe 461 is provided with a blowing nozzle 462 facing the tool changing port. The blowing nozzle 462 can spray high-pressure air in the direction of the tool changing port when needed to blow off the cutting chips, thereby preventing the cutting chips from entering the tool magazine module 400 and affecting the operation of the tool magazine module 400.

[0032] The working principle of this embodiment is as follows:

[0033] When the machine tool spindle 300 needs to change the tool after completing a stage of workpiece processing, the tool magazine module 400 rotates to the tool changing port close to the spindle head of the machine tool spindle 300, and then the tool clamp fixing plate 420 rotates an empty elastic tool clamp 430 to the bottom of the spindle head. At this time, the spindle head moves downward until the tool to be replaced on the spindle head is stuck in the empty elastic tool clamp 430, and then the spindle head releases the tool. During this process, the air nozzle 462 will blow the chips off the tool to be replaced, and then the tool clamp fixing plate 420 continues to rotate, and rotates the elastic tool clamp 430 loaded with the required tool holder to the tool changing port, and then the spindle head clamps the tool holder downward, and then moves upward, so that the tool holder leaves the tool magazine module 400 to complete the tool changing process.

[0034] Example 2, refer to the attached Figure 4 ~Attached Figure 6The content of Example 1 is based on the content of Example 1, and a chip blowing guide plate 470 is fixedly provided on the tool magazine fixed plate 410. The chip blowing guide plate 470 is arranged on the side of the tool changing port away from the air blowing nozzle 462, and the left and right sides of the lower end of the chip blowing guide plate 470 are respectively connected to the top chip guide groove 471, and the chip blowing guide plate 470 can block the chips blown out by the air blowing nozzle 462, and at the same time guide them downward to the two top chip guide grooves 471. Correspondingly, a base chip guide groove 110 is respectively provided on both sides of the horizontal sliding track, and the base chip guide groove 110 is inclined compared to the horizontal plane. The lower ports of the two top chip guide grooves 471 are respectively arranged above the two aforementioned base chip guide grooves 110, so that most of the cutting chips falling from the two top chip guide grooves 471 will directly fall into the base chip guide groove 110 instead of flying everywhere, which is also more convenient to clean.

[0035] In a more optimized solution, as shown in the attached Figure 6 As shown in , the tool changing port is also provided with a tool magazine chip guard plate 480 which can open and close automatically. When the tool is not changed and the air nozzle 462 is blowing chips, the tool magazine chip guard plate 480 can close the tool changing port to prevent the cutting chips from entering the tool magazine module 400 from the tool changing port.

[0036] At the same time, in order to protect the transverse sliding track and the longitudinal sliding track, transverse telescopic guard plates 510 are provided between the two ends of the transverse sliding track and the transverse slide 500, and longitudinal telescopic guard plates 610 are provided between the two ends of the longitudinal sliding track and the workbench 600. This can prevent cutting chips from entering the transverse sliding track and the longitudinal sliding track when the transverse slide 500 and the workbench 600 are working.

[0037] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal", "head, tail" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings.
