Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] As shown in the figure, the rotary engine block milling end face tooling of this embodiment includes a U-shaped tooling body composed of a bottom plate 1 and side plates 2 welded on the left and right sides of the bottom plate. Two rows of support columns 3 supporting the bottom surface of the engine block, each column of support columns includes three support columns, and the support surfaces of each support column are located on the same vertical plane; each support column is provided with a cylinder 4, and the cylinder The piston rod of the piston rod is connected with a workpiece pressing plate 5 that compresses the top surface of the engine block;

[0020] Two locating pins 6 cooperating with the cylinder holes on the engine block are also arranged on the bottom plate between the left and right columns of support columns;

Abstract

The invention discloses a rotary tooling for milling of an end surface of an engine cylinder. The rotary tooling comprises an U-shaped tooling body, a support column, an air cylinder, a workpiece press plate, a positioning pin, a left bracket, a right bracket, a left positioning pin, a right positioning pin and a bolt. The rotary tooling for milling of the end surface of the engine cylinder has the advantages that after one end surface of the engine cylinder is milled, a nut on the bolt is loosened, the bolt is taken out, the U-shaped tooling body is rotated by 180 degrees, then the bolt is inserted again, the nut is tightened, and the other end surface of the engine cylinder can be milled, so the processing time is greatly shortened, and the production efficiency is improved; the engine cylinder is positioned by the support column and the positioning pin, and the workpiece press plate is driven by the air cylinder to press and loosen the workpiece, so the clamping and loosening of the workpiece are convenient and rapid; the rigidity of the U-shaped tooling body is good, so the problem of stress vibration of the tooling during processing is solved, and the processing quality can be reliability guaranteed.

Description

technical field [0001] The invention relates to a tool, in particular to a tool for milling the end face of an engine cylinder body. Background technique [0002] The processing quality of the end face of the engine cylinder block is relatively high, and tooling is required to ensure the processing quality of the end face during the processing. [0003] The engine block end face milling tooling in the prior art can only realize the processing of one end face, that is, after one end face is processed, the engine block needs to be disassembled and then transferred to another machine tool for processing the other end face. processing. It takes a long time to repeatedly clamp and transfer the workpiece, which makes the production efficiency low, and the two end surfaces are processed on different machine tools, and the clamping and positioning benchmarks are different, which easily leads to the problem of out-of-tolerance parallelism between the left and right end surfaces. ...
