Description
Technical field
The utility model relates to Machine Design and processing technique field, particularly a kind of tool-bar for accurately boring frock.
Background technology
In machining, the processing of endoporus is very common, and conventionally, the processing of endoporus completes by equipment such as lathe, boring machine, milling machine, drilling machines.
The endoporus processing that diameter is little is easy to realize, and is subject to device-restrictive little, and general manufacturer all can complete.But large diameter endoporus is easy to exceed the range of work of lathe, and can be because the requirement of some form and position tolerances of drawing, on machine tool, processing cannot guarantee precision, complete processing and can only use heavy duty machine tools, and this makes a lot of manufacturers because the restriction of equipment cannot complete processing.
For example, box body of speed reducer as depicted in figs. 1 and 2, maximum diameter of bore is φ 1200mm, also has inner hole of bearing seat in casing chamber.Wherein, between the side opening being oppositely arranged on casing two sides, axiality requires φ 0.03mm, and on same side, adjacent two side holes center distance tolerance is 0.03mm.If process on vertical car, workpiece need to turn over individual, because two side holes is not that clamped one time machines, thereby cannot guarantee the axiality requirement of two side openings; If process above-mentioned side opening on boring machine or planer-type milling machine, although can complete processing, but because of diameter of bore larger, and the common about 830mm of tool-bar for accurately boring maximum machining diameter, cannot reach the range of work needing, as shown in Figure 3, the processing diameter of common tool-bar for accurately boring is determined to the distance (being that the center of balladeur train 2 is to the distance in boring cutter 7 outsides) in boring cutter 7 outsides by the center of cutterhead 1.Therefore, complete processing just needs large specification tool-bar for accurately boring customized or uses large-sized numerical control boring machine.
