Background technology
The stator of screw pump is cast in steel part overcoat by nitrile rubber lining and is formed up to now, elastomer stator very easily damages, but because screw pump spiral cavity geometric parameter is many, dimensional tolerance is difficult to ensure, it is large to cut difficulty, up to the present existing many businessmans begin one's study metal stator of screw pump; Because the material hardness of metal stator is high, milling head of the prior art can not satisfy the demands.
Technology contents
The object of this technology is to provide a kind of Inner spiral groove cutter head that rapidly and efficiently can process inner spiral groove, and the inner spiral groove precision that it processes is high, dimensional tolerance is little, is especially suitable for the screw type cavity of processing metal stator of screw pump.
The technical scheme that this technology is taked is: this Inner spiral groove cutter head comprises two casings, and two casings can relatively rotate around a rotating shaft; Roughing tool, finishing tool for processing inner spiral groove arrange two casings respectively, and the transmission mechanism driving roughing tool and finishing tool to rotate is arranged in two casings; Roughing tool, finishing tool arrange along the axis of rotating shaft; When two casings relatively rotate, roughing tool and the angle of finishing tool in rotating shaft circumferential direction can be changed; Be connected with angle adjustment retaining mechanism between two casings.
The beneficial effect of this technology: this technology have employed two body structures rotated, changes the spiral angle between two casings, roughing tool and finishing tool can be made can be positioned at same helicla flute, process simultaneously to same helicla flute.Why angle adjustment retaining mechanism is set, is in order to after adjusting roughing tool and the angle of finishing tool in rotating shaft circumferential direction, by angle adjustment retaining mechanism, two casings is locked, two casings can not be relatively rotated.Angle adjustment retaining mechanism can have multiple, such as, can be to be distributed on multiple bolt in rotating shaft circumference; Can also be that to have with rotating shaft on a casing be the annular T-slot of axis, the bolt stretching into tommyhead bolt be connected with another casing; Can also be the angle adjustment retaining mechanism of other structure, just want to realize can to unclamp when needs two casings relatively rotate around the shaft, when not needing to relatively rotate can the position of two casings relatively fixing.Roughing tool first carries out roughing to helicla flute, and finishing tool carries out fine finishining to roughing rear screw groove again, ensure that working (machining) efficiency.The more important thing is, roughing tool and finishing tool are arranged on two casings being connected, and drive roughing tool and finishing tool to rotate by a transmission mechanism, and a tool setting, processes simultaneously, ensure that machining accuracy, and workpiece can a step precise forming.
Above-mentioned Inner spiral groove cutter head, roughing tool has two, symmetrical with shaft axis; Finishing tool has two, symmetrical with shaft axis.Such two thick (essence) process tools can process two helicla flutes simultaneously, and not only efficiency is high, and Inner spiral groove cutter head stress balance, vibrates little, further increases the precision of processing.
Above-mentioned Inner spiral groove cutter head, transmission mechanism comprises output shaft and middle bevel gear, and the cutterhead of roughing tool is arranged on output shaft; The end of the middle angular wheel shaft of middle bevel gear arranges finishing tool; Output shaft and angular wheel shaft rotate respectively and are arranged on two casings; Output shaft and middle angular wheel shaft perpendicular.The end of middle angular wheel shaft arranges the structure of finishing tool, breaches traditional transmission and describes, simplify transmission mechanism.
Above-mentioned Inner spiral groove cutter head, transmission mechanism also comprises the first bevel gear, the 3rd bevel gear, the first spur gear, exports spur gear; First bevel gear is engaged with the 3rd bevel gear by middle bevel gear; , the first spur gear be fixed on the 3rd angular wheel shaft engages with the output spur gear be fixed on output shaft.Preferably, roughing tool has two, symmetrical with shaft axis; In transmission mechanism, output shaft, output spur gear all have two; Each output shaft is provided with cutterhead and an output spur gear of a roughing tool; First spur gear engages with two output spur gears simultaneously; Finishing tool has two, is arranged on the two ends of middle angular wheel shaft with shaft axis relatively symmetrically.This Inner spiral groove cutter head structure is simple, compact, less in the size in the radial direction of rotating shaft, is particularly suitable for the processing of internal spiral fluted.Two thick (essence) process tools can process two helicla flutes simultaneously, and not only efficiency is high, and Inner spiral groove cutter head stress balance, vibrates little, further increases the precision of processing.
