图1所示刀架,其切削半径可以调整。内外半径尺寸可在31.75mm 内准确滑动。草图上没有注明尺寸,显然是为了适应每个加工者的要求,以便按不同尺寸制造这种装置。回转板上设有 T 型槽,通过 T 型螺栓固定镗杆、青铜衬套和特氟隆垫圈,这样夹紧可靠並旋转轻松。刀具装好后,调整零位。首先用两个特制的心轴将镗杆夹紧在两个回转板的中心点上,如转动手柄,刀尖不动,则说明调整正确。这时,可根据需要,在每块回转板上要钻一个调整销孔(如图)。然后装入调整销,在保证镗杆就位的同时,只要在镗杆和调整
The tool holder shown in Figure 1, the cutting radius can be adjusted. Internal and external radius dimensions can be accurately within 31.75mm sliding. The sketch does not indicate the size, apparently in order to meet the requirements of each processor, in order to manufacture such devices in different sizes. The T-slot on the swivel plate holds the boring bar, bronze bushing and Teflon washer with T-bolts so that the clamp is secure and swivels easily. After the tool is installed, adjust the zero position. First of all, with two special mandrels will be boring bar clamped in the center of the two rotary plate, such as turning the handle, the tip does not move, then the adjustment is correct. At this time, according to need, in each turn plate to drill an adjustment pin hole (Figure). Then install the adjusting pin, while ensuring that the boring bar is in position, only need to adjust the boring bar
