Abstract
The invention provides a high-precision machining method of double symmetric key slots of a water pump shafting component, and is simple and high in machining precision. The method is characterized in that the method is specifically as follows: firstly, locating both ends of a shafting component to be machined by V-shaped irons; then fixedly mounting a parallel reference meter at one end of the shafting component to be machined by a bolt; aligning the parallel reference meter by a dial indicator; next, machining a first key slot; after the machining of the first key slot is finished, overturning the shafting component to be machined together with the parallel reference meter by 180 degrees; aligning the parallel reference meter again by the dial indicator; and at last, machining a second symmetric key slot.
Description
Technical field
The present invention relates to pump shaft is the part processing technical field, is specially a kind of water pump shafting components high accuracy symmetric double keyway processing method.
Background technology
The water pump shafting components, often design the keyway (promptly two key) that two symmetries are arranged as pump shaft, pull rod shaft, blade shank axle etc., the position degree required precision height of this class symmetric double key, traditional double key processing technology mainly adopts index dial to carry out 180 ° of calibration processing, turn over 180 degree back processing opposite side symmetry keys with index dial after promptly processing a keyway, it is bigger that its shortcoming is that the precision of its position of double bond degree is influenced by the index dial precision, and the relative position that two keyways are 180 ° can not obtain guaranteeing more accurately.This method is because the indexing accuracy problem usually makes that the two key symmetric position degree that process are overproof.
Summary of the invention
At the problems referred to above, the invention provides a kind of water pump shafting components high accuracy symmetric double keyway processing method, its method is simple, machining accuracy is high.
Its technical scheme is such, it is characterized in that: at first shafting components to be processed two ends are located by v block, by bolting a parallel station meter is installed at an end of described shafting components to be processed then, with the described parallel station meter of dial gauge centering, then carry out the processing of article one keyway, after described article one keyway completion of processing, described shafting components to be processed is turned over turnback together with described parallel station meter, use the described parallel station meter of dial gauge centering again, carry out the processing of second symmetry keyway at last.
Adopt the inventive method to carry out the processing of water pump shafting components high accuracy symmetric double keyway, its method is simple, the symmetry precision height of keyway.
Description of drawings
Fig. 1 is the inventive method water pump shafting components symmetric double keyway processing schematic diagram.
The specific embodiment
See Fig. 1, at first shafting components to be processed 1 two ends are located by v block 2, then at an end of shafting components 1 to be processed, with parallel station meter 3 of bolt 5 fixed installations,, then carry out the processing of article one keyway with the parallel station meter 3 of dial gauge centering, after article one keyway completion of processing, shafting components 1 to be processed is turned over turnback together with described parallel station meter 3, use the parallel station meter of dial gauge centering again, carry out the processing of second symmetry keyway at last.Among Fig. 1,4 is milling cutter.Wherein, the installation of parallel station meter 3 generally can utilize the threaded centre bore of axle head on the shafting components, fixes by bolt 5; Also can process at least one technology screw, fix with bolt 5 again at axle head.
