[0026] Figure 1-4 As one embodiment of the utility model, a protective device for a five-axis machining center with a swing head includes a machine tool body 1, an outer cover of the machine tool body 1 is provided with a sliding protective door 3 on the front side of a protective cover 2, a machine tool swing head 4 is provided on the inner side of the sliding protective door 3, a corresponding double-swing workbench is provided below the machine tool swing head 4, a swing head protective plate 5 for protecting the machine tool swing head 4 is provided on the front side of the machine tool swing head 4, and an automatic chip removal mechanism 6 for automatically collecting and discharging chips after cutting processing is provided on the bottom wall of the protective cover 2 corresponding to the machine tool swing head 4. In actual work, the workpiece to be processed is placed on the top of the double-swing workbench through a pre-set program, and then the workpiece is processed in cooperation with the machine tool swing head 4. When placing the workpiece, the sliding protective door 3 is opened to both sides. After the placement is completed, the sliding protective door 3 is closed to realize that the machine tool body 1 is enclosed in the protective cover 2 as a whole, which can not only protect safety but also prevent dust and chips from splashing during processing;

[0027] The swing head protection plate 5 includes a fixed plate 51 fixed to the front side of the machine tool swing head 4, and a blowing part 52 is provided in the fixed plate 51 for blowing off the cutting debris. The side wall of the fixed plate 51 facing the machine tool swing head 4 is provided with a wire clamping groove 53 for clamping the line of the machine tool swing head 4. In actual work, the fixed plate 51 moves with the movement of the machine tool swing head 4 to protect the machine tool swing head 4. At the same time, the blowing part 52 blows the debris after cutting by the machine tool swing head 4 and the double-swing worktable away from the double-swing worktable to prevent the debris from remaining on the workpiece and affecting subsequent processing.

[0028] The length of the fixed plate 51 is greater than the vertical length of the machine tool swing head 4, and the width of the fixed plate 51 is greater than the width of the machine tool swing head 4 to ensure that the fixed plate 51 will face the machine tool swing head 4. The bottom of the side wall of the fixed plate 51 is provided with an inclined surface 511 for the blowing part 52 to extend out. The blowing part 52 includes a vent pipe 521 fixedly arranged in the fixed plate 51, and the top of the vent pipe 521 is connected with a blowing valve. The bottom end of the vent pipe 521 is perpendicular to the inclined surface 511, and the bottom end of the vent pipe 521 passes through the outside of the inclined surface 511 and extends to the bottom of the machine tool swing head 4. In actual work, when the workpiece is cut, the blowing valve is started to make the air flow pass through the vent pipe 521, and the bottom end of the vent pipe 521 passes through the outside of the inclined surface 511 corresponding to the bottom of the machine tool swing head 4, so that the air flow in the vent pipe 521 is blown toward the double swing workbench to blow off the debris remaining on the double swing workbench.

[0029] The wire clamping groove 53 includes a mounting bar 531 horizontally arranged on the fixing plate 51 toward the side wall of the machine tool swing head 4. The mounting bar 531 is provided with a plurality of limiting rings 532 on the side wall facing the machine tool swing head 4 for limiting the line. The limiting ring 532 is a hollow cylinder. The outer side of the side wall of the limiting ring 532 is fixedly connected to the mounting bar 531. The side wall perpendicular to the limiting ring 532 and the mounting bar 531 is provided with a through groove 533 for the line to pass through. In actual work, the line of the machine tool swing head 4 is placed in the limiting ring 532 through the through groove 533, so that the limiting ring 532 clamps the line. When the machine tool swing head 4 is frequently moved for processing, the line is limited, the line direction is optimized, and the cable is effectively protected from damage.

[0030] The automatic chip removal mechanism 6 includes a transmission belt 61 corresponding to the bottom of the machine tool swing head 4. The transmission belt 61 extends horizontally to the outer side of the side wall of the protective cover 2 and is provided with an inclined conveying part 62 extending obliquely upward. In actual work, the chips after cutting and the chips blown off by the blowing part 52 fall to the top of the transmission belt 61. The chips are conveyed to the inclined conveying part 62 through the transmission of the transmission belt 61. The inclined conveying part 62 extends obliquely upward, which can effectively avoid the loss of cutting fluid. A discharge port is provided below the inclined conveying part 62. When the debris material is conveyed to the transmission belt 61, the transmission belt 61 turns down and puts the debris material into the discharge port to realize automatic discharge and collection of the debris material.

[0031] A partition 63 perpendicular to the surface of the transmission belt 61 is provided above the transmission belt 61. The partition 63 is used to limit the debris above the transmission belt 61. When the debris falls above the transmission belt 61, the partition 63 separates the debris due to the inclined setting of the inclined conveying part 62 to ensure the efficiency of debris transportation. When transported to the inclined conveying part 62, the debris moves downward due to gravity and contacts the side wall of the partition 63, and the partition 63 blocks the falling of the debris and pushes the debris to the top of the inclined conveying part 62.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
