[0029] It also includes a transparent window 15 , and the rear side wall of the machine tool body 2 is detachably provided with the transparent window 15 .

[0030] The staff first installs the spare tools in the tool cylinder 104 on the left side of the sliding tool disc 8 from the transparent window 15 on the rear side of the machine tool body 2, and inputs the encoder corresponding to the information of different types of tools into the control panel 3, and then installs the transparent window 15. When it is necessary to change the tool, the staff inputs the command through the control panel 3 and then drives the tool mounting seat 5 to reset to the initial position through the multi-stage sleeve guide mechanism 4. At the same time, the encoder of the tool to be replaced is input into the control panel 3. The controller in the control panel 3 controls the rotation motor 9 to work, and the rotation motor drives the sliding shaft 7 and the sliding tool disc 8 to rotate. When the required tool is in the front position, the rotation motor 9 stops working. At this time, the micro single-acting cylinder 112 on the right drives the rack 113 to move backward, and the rack 113 engages with the gear 111, and then the rotating shaft 102 drives the mounting frame 103 and the tool barrel 104 to rotate forward 90°. The ball groove 143 of the mounting frame 103 is engaged with the corresponding card ball 142 on the L-shaped seat 141, which fixes the tool barrel 104 and the tool to prevent displacement during replacement.Through the slotted hole on the front side wall of the installation box 6, the tool to be replaced and the tool being used by the machine tool are at the same horizontal position. The staff inputs instructions through the control panel 3. The controller in the control panel 3 controls the drive motor 133 to drive the installation shell 134 and the claw 135 to rotate 90°. The semi-arc grooves on both sides are correspondingly clamped on the two tools. Then the second electric push rod 138 extends to drive the connecting rod 136 to move, and the claw 135 slides along the semi-arc groove. The teeth of the semi-arc groove cooperate with the position of the clamping ring of the tool, and then the claw 135 cooperates with the semi-arc groove of the installation shell 134 to complete the fixation of the tool.

The first cylinder 132 is reset to drive the two tools to move backward. The new tool is installed on the tool mounting seat 5 of the machine tool, and the replaced tool is installed in the tool barrel 104. Then the second electric push rod 138 is controlled to reset, and then the claw 135 is reset. By rotating the driving motor 133 in the opposite direction, The driving motor 133 drives the mounting shell 134 and the claw 135 to rotate 90° to a vertical state, and the micro single-acting cylinder 112 on the right drives the rack 113 to move forward, and the rack 113 meshes with the gear 111, and then the shaft 102 drives the mounting frame 103 and the tool barrel 104 to reset, and the ball groove 143 of the mounting frame 103 is engaged with the corresponding card ball 142 on the L-shaped seat 141 to fix the tool barrel 104. If the tool of the machine tool collapses, when replacing and resetting, the staff first controls the micro single-acting cylinder 112 on the right to drive the rack 113 to move forward to reset the tool barrel 104, and then starts the first The electric push rod 122 is shortened to drive the guide wheel 123 to move to the left, and the guide wheel 123 drives the sliding tool disc 8 to move to the left. By starting the micro single-acting cylinder 112 on the left, the rack 113 is driven to move backward, so that the front tool barrel 104 passes through the straight hole on the front wall of the installation box 6. At this time, the tool is reset and installed, and the damaged tool is installed in the tool barrel 104 of the damaged tool disc on the right. The device uses an ingenious mechanical structure and the control algorithm of the control panel 3 to achieve fast and accurate tool replacement and distribution between the two, greatly shortening the tool change time, improving processing efficiency, and enhancing the intelligent level of tool management.
