Description
Technical field
The utility model relates to a kind of processing tool, is specifically related to a kind of processing tool of gear-box.
Background technology
Gear-box is the critical product of locomotive or subway vehicle traction drive part.Described gear-box is generally divided into casing and case lid, and described casing comprises with case lid that respectively two require coaxial dead eye.For requirement and the assurance gear shaft of gear-box anti-leak, can install smoothly, to the axiality of these two pairs of dead eyes, require higher.Conventional gearbox process technology be casing is combined with case lid together with processing.But because the combine degree of depth of the gear-box that forms of casing and case lid is darker, make the knife bar of the cutter for processing all longer.When the knife bar of process tool is longer, can affect the rigidity of knife bar, easily cause knife bar bending even to fracture.Thereby cause the quality of product unstable, be not suitable for batch production.And the combination of casing and case lid adds man-hour, generally only have this pair of casing of combination processing to match with the dead eye of case lid, if casing or case lid damage, when changing another casing or case lid and assembling, easily occur corresponding dead eye disalignment and cannot install.Namely interchangeability is poor, has one to scrap in casing and case lid, all can scrap for two, causes the wasting of resources, cost to increase.If casing, case lid are processed separately by numerical control device, owing to also there is no a kind of frock for the processing of case body and case cover of gear case branch mailbox in prior art, make not only very high to requirement on machining accuracy to the independent processing of casing, case lid, clamping inconvenience and working (machining) efficiency are low, processing cost is high, interchangeability is poor.
On the other hand, in prior art, also there are the casing of pair gear-box and the processing method of case lid branch mailbox processing.The Chinese patent that is 200910190984.3 as application number discloses the processing method of a case body and case cover of gear case, but the method all will be played coding and three-dimensional report after often processing a case lid, according to size, match the casing of answering, so just cause casing of every processing all will match with the case lid of reference numeral, the interchangeability that is unfavorable for its assembling, is not suitable in batches or produces in enormous quantities.
