Problems solved by technology

[0002] In the field of mechanical processing, the diameter of the thrust surface of the diesel engine cylinder block is larger than the previous hole and the rear hole of the thrust surface. It is difficult to process a large hole through a small hole. A milling cutter with a small hole, after passing through the previous hole, mills the thrust surface by circular interpolation, the tool is radially stressed, which is easy to cause tool vibration, poor processing stability, and low processing efficiency. Bottleneck process in processing line
Due to the lack of a cutting tool and its processing method for machining the thrust surface of diesel engine cylinder block, circular interpolation milling is used to process the thrust surface, and another knife is used to process the chamfering of the thrust surface, the processing efficiency is low, the tool consumption is large, and the Enterprises increase the cost of processing

Abstract

The invention discloses a tool for machining a thrust surface of a diesel engine cylinder block and a machining method thereof. The tool for machining the thrust surface of the diesel engine cylinderblock comprises a tool body and the thrust surface of the cylinder block, wherein a first stepped tool apron, a second stepped tool apron, a third stepped tool apron and a fourth stepped tool apron are arranged at the bottom of the tool body;a tool body receding part is arranged on the top surface of the tool body; the first stepped tool apron, the second stepped tool apron, the third stepped toolapron and the fourth stepped tool apron are all triangular; and one edge of the first stepped tool apron and one edge of the second stepped tool apron form an included angle with the horizontal line.The tool for machining the thrust surface of the diesel engine cylinder block provided by the invention is simple in structure and convenient to operate; machining of the thrust surface of the dieselengine cylinder body is achieved through the four steps of the tool body, so that the problems that the machining efficiency of the thrust surface is low and the stability is poor are solved; and machining of the thrust surface and chamfering of the thrust surface are integrated on one tool, so that investment of a chamfering tool is reduced, the machining cost is saved, and economic benefits arebrought.

Description

Technical field [0001] The present invention belongs to the field of mechanical manufacturing, and is specifically a tool for processing a diesel cylinder block surface. Background technique [0002] In the field of machining, the diameter of the diesel cylinder block surface, the front aperture and the latter aperture of the push surface are large, and the macropole is difficult by the small hole processing, and the method of frequent use is, using a diameter ratio A small milling cutter disk, after the previous hole, walk the circular interpolation milling surface, the cutter radial force, easy to cause the shock knife, the processing stability, low processing efficiency, the thrust surface processing is a machine Processing the bottleneck procedure of the production line. Due to the lack of the tool and processing method thereof, the processing stop surface is taken with an arc interpolation milling, and the processing stop surface is chamfered, and the processing is low, the ...
