The diesel of the overall modular machine tool and jig for thick mill the surface and bottom of cylinder body of the diesel engine
Abstract: The diesel of the overall modular machine tool and jig are designed for thick mill the surface and bottom of cylinder body of the diesel engine. The system design mainly completes “three charts and a card” about the two-sided mill modular machine-tool. The jig design is to complete the structure plan, the assembly drawing and the parts drawing.
According to the cylinder body size, the shape, the material, processing request and so on spot structure and processing precision, surface roughness, determined selects the horizontal-type two-sided mill aggregate machine-tool; In order to realize the work piece to enter quickly with the labor enters matches by moves the work table; Is processed the plane is the big plane, the material is HT250, therefore cutting tool choice hard alloy face cutter. The jig installs in moves above the work table. In is processed the components the localization aspect, this plan has used "two sells at the same time" the locate mode, by achieves the good localization effect. Clamps is through manual clamps, clamps by four clamps realizations, like this can very good prevent clamps under the action of force the work piece to have the deformation. Because is processed the components volume, the weight is big, therefore uses the support plate supporting. Moreover designs the analysis through the jig error, can guarantee the processing precision well.
