Abstract
The utility model discloses a composite reamer for machining a conduit hole and a valve seat ring hole of an engine cylinder block. The composite reamer sequentially comprises a clamping part, a knife rod, a chamfering knife part and a reamer part from the back to the front. The utility model has the benefits as follows: the composite reamer can machine the valve seat ring hole and the valve conduit inner hole through one step; thus, the composite reamer is high in machining efficiency and machining precision.
Description
Technical field
The utility model relates to a kind of reamer, particularly a kind of combination cutter of processing engine cylinder block guide hole and valve retainer hole.
Background technology
In the M14/M12 engine cylinder-body of STEYR company, cylinder body and cylinder cap integrate, and are a kind of novel engine cylinder body technique of STEYR company.In this engine cylinder-body, the requirement on machining accuracy of the valve retainer hole conical surface and valve guide bushing is higher.
According to traditional processing mode, the valve retainer hole conical surface, valve guide bushing endoporus are processed respectively, and the mode of this processing is respectively difficult to ensure processing form and position tolerance precision between the two.
Therefore, also require further improvement for the process technology of the valve retainer hole conical surface, valve guide bushing endoporus, to improve the processing form and position tolerance precision of the two.
Utility model content
Goal of the invention of the present utility model is: for the problem of above-mentioned existence, provide a kind of combination cutter of processing engine cylinder block guide hole and valve retainer hole, can disposablely complete the processing of valve retainer hole and valve guide pipe inner hole.
The technical solution adopted in the utility model is such: a kind of combination cutter of processing engine cylinder block guide hole and valve retainer hole, comprises clamping part, knife bar, rose reamer portion and reamer portion from back to front successively.
As preferably, described knife bar diameter is 34mm, and long is 166mm.
As preferably, described rose reamer portion diameter is 34mm, and long is 14mm, and fillet surface and knife bar central shaft angle are 60 °.
As preferably, described reamer portion overall length is 90mm, wherein processes segment length 65mm, and diameter is 7mm, the transition segment length 25mm between processing sections and rose reamer portion.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are: can disposablely complete the processing of valve retainer hole and valve guide pipe inner hole, working (machining) efficiency is high, and machining accuracy is high.
