Cutterhead the place ahead is provided with the driving mechanism of tool U type piece, and when broach shell moved to the gap position of disk frame side, it was fulcrum with the card tip of side that the driving mechanism of tool U type piece can drive broach shell, and swings backward from the indentation, there of disk frame.Because the card tip is positioned at the side of broach shell, and has a suitable spacing, so broach shell is when doing the action of falling the cutter, and the distance of further hilt and tool change arm, and then the length of shortening tool change arm reach the setting and the action of convenient peripheral element.

The good material of the available wear resistence of ring pad of disk frame is made.

The annular block face of cutterhead can have a gradient.

In addition, cutterhead is located on the central shaft with bearing bracket stand, and uses a drive power source.

When cutterhead drives broach shell when central shaft rotates, utilize annular block face to replace the roller of broach shell, inwardly swing to prevent broach shell, utilize the ring pad of the disk frame that is resisted against the broach shell rear simultaneously, outwards swing to prevent broach shell, thereby make broach shell in rotation process, remain on horizontal direction, so can be automatically, spacing each broach shell swing exactly.

Disk frame in the utility model must outwards not be convexly equipped with the annular guide channel of certain-length, and a ring pad need only be set to cooperate the block face of cutterhead dimpling, can broach shell is spacing, and then the consumptive material of limit assembly is reduced more.
