[Prior art] As shown in Figs. 1 and 2, a conventional tool changing device 10 of a processing machine has a function of grasping a tool 14 from a tool magazine 12 and transferring the tool 14 to a processing machine spindle 13. The tool changing device 10 has a clamp arm 1 丨 that can be raised and lowered, and a rotating mechanism (not shown) that can drive the clamp arm 11. The knife clamping arm 11 has a reverse first taking slot 111 and a second taking slot 112 'which are δ and placed in two sections, respectively. A first top cutter claw 113 and a second top cutter claw ι14 in the sipes 1 丨 丨 and ι12. In the normal state, the second tool slot of the tool holder arm 11 is firstly grabbed a new tool 141 from the tool magazine 12 for backup, and then lowered and rotated 90 degrees in the opposite direction so that the tool holder arm 11 is located at Between the tool magazine 12 and the spindle i 3 of the processing machine (as shown by the imaginary line position in FIG. 1). To replace the old tool 142 set on the main shaft 13 of the processing machine, first make the cool tool arm 11 rotate 90 degrees in the forward direction, and then use the rotating force to make the old tool 142 snap into the first tool slot. m, and the old tool 142 can be restrained by the first top jaw 113, so that the old tool 142 is clamped behind the clamping knife # 11 ', so that the clamping arm 11 is lowered and rotated 1 80 °, it is converted into that the second tool slot 112 and the new tool 141 are located below the main shaft 13 of the processing machine, and then the clamping arm u is raised to make the new tool 141 4 groups not in the processing machine. After the main shaft 13 is rotated by 90 degrees in the reverse direction, the second tool slot 112 can be released from the new tool 141 and the tool changing operation can be completed. After that, the first top cutter claw 113 is retracted to disengage the old cutter 142 from the first cutter slot Π1, and then the clamp arm π is rotated 90 ° in the forward direction to obtain the cutter by the first cutter. The slot Π1 grabs another new tool from the tool magazine 12 and changes to a state where the second tool slot 112 is used to hold the old tool to be replaced. Although the tool changer 1 has the function of automatic tool change, it still has the following shortcomings ... 1. Because the rotation direction of the clamping arm 11 must be changed in the forward and reverse directions to replace the old tool 142. The effect of grasping the new tool 141, as far as the design of the automatic tool change is concerned, having a knife clamping arm u is more troublesome, resulting in the lack of long waiting time and poor work efficiency. 1. Although the knife clamping arm 11 can be rotated by the rotating mechanism, there is a rotation instability in the whole, which seriously affects the lack of tool changing quality. 3. Because the old cutter 142 is caught in the cutter slots ⑴, 112 by the rotating force, and is then clamped and positioned, there is a lack of damage to components due to impact. [New content] The purpose of this new i ’is to provide an automatic tool changer for the Guardian, which has fast tool changing speed and good quality, and can avoid component damage.
