The specific embodiment
Below in conjunction with accompanying drawing 1 to Fig. 3 the specific embodiment of the present utility model is further set forth:
A kind of automatic tool changer arm assembly, it comprises the tool changing parts and falls tool rest, described tool rest comprises the bearing of support, tool arm seat, horizontal rotating shaft, horizontal rotating shaft and drives the driver part that horizontal rotating shaft rotates, fixedly connected with the tool arm seat in described tool changing parts lower end, the tool arm seat is connected with horizontal rotating shaft.
Above-mentioned driver part is oil cylinder, and it comprises cylinder body, piston and rotating shaft, and piston is arc, described piston is connected with horizontal rotating shaft, cylinder body is cylindricality, is provided with the cavity with the piston correspondingly-shaped in the cylinder body, and the cavity both sides connect oil-feed port and the oil-out of oil hydraulic system respectively.
Above-mentioned tool changing parts comprise the telescoping mechanism that tool change arm, driving shaft, drive driving shaft stretch and the rotating mechanism that drives drive shaft turns, and described tool change arm is fixedlyed connected with driving shaft, and the tool change arm two ends are respectively arranged with the cutter pawl.
Also be provided with rotary positioning mechanism on the above-mentioned main shaft, it comprises the holder that is arranged on the driving shaft, is arranged on locating shaft and pneumatic cylinder on the holder, locating shaft is connected with the push rod of pneumatic cylinder, is provided with the positioning component corresponding with locating shaft below tool change arm.
Above-mentioned telescoping mechanism and rotating mechanism are hydraulic cylinder.
Tool rest and tool changing parts are fallen in automatic tool changer arm assembly of the present utility model setting, and the effect of tool rest of falling is to make the tool changing parts can turn to horizontal direction, convenient horizontal cutter head tool changing.The horizontal rotating shaft of tool rest drives by oil cylinder, the tool changing parts are fixedlyed connected with the tool arm seat, horizontal rotating shaft is fixedlyed connected with the tool arm seat, therefore, can make the tool changing parts turn to horizontal level from the upright position as long as horizontal rotating shaft rotates 90 °, can finish the action of tool changing by cutter pawl, tool change arm, rotating mechanism and the telescoping mechanism of tool changing parts.When needs carry out vertical tool changing, confirm at first whether cutter is arranged above the cutter pawl, if cutter is arranged, go back cutter earlier, driving shaft descends, and the tool rest that falls moves to gets/go back cutter position, driving shaft rises, and also to tool magazine, the tool rest that falls is got back to original position with hilt, begin turn to required cutter in the tool magazine cutter storehouse this moment, and the tool rest that falls moves to again gets/go back cutter position, and the cutter pawl begins to get cutter, leave tool magazine after getting cutter, at this moment, the main shaft of vertical cutter head begins to move to the tool changing point position of setting, and the tool rest that then falls begins to move to tool changing point position, empty cutter pawl begins to grab the cutter of main shaft, grabbed after the cutter, driving shaft descends, and Rotate 180 °, cause cutter pawl location swap, driving shaft rises to main shaft nose place, and the beginning tool changing is after tool changing finishes, main shaft leaves the tool changing point, the tool rest that falls is back to original position, and this moment, vertical tool changing finished, and the tool magazine door can be shut.When carrying out horizontal tool changing, the action of going back cutter equally earlier and getting cutter, the tool rest that falls is then got back to initial position, the hydraulic oil cylinder driving horizontal rotating shaft rotates 90 °, at this moment, drive shaft turns is to horizontal level, and tool arm transfers to vertically simultaneously, driving shaft stretches out, this moment, horizontal cutter head moved to corresponding tool changing point place, and empty cutter pawl is got the cutter on the horizontal cutter head earlier, and driving shaft shrinks then, driving shaft Rotate 180 °, driving shaft is stretched to tool changing point position thereupon, and horizontal cutter head begins to grab cutter then, after having grabbed, horizontal cutter head leaves the tool changing point, driving shaft shrinks, and the tool rest that falls is got back to initial position, and oil cylinder drives the horizontal rotating shaft rotation then, make driving shaft go back to plumbness, finish tool changing.
