Method for deburring flywheel casting

Abstract

The invention discloses a method for deburring a flywheel casting part, which is characterized by comprising the following steps of: a, designing a deburring tool; b, installing the horizontal bottomplate on a workbench of the milling machine; c, horizontally placing the flywheel casting on a horizontal bottom plate; d, starting an air cylinder, driving the movable pressing block to move to the right by the air cylinder, and pressing the flywheel casting piece to the right; step e, the milling cutter of the milling machine moves downwards, and the program programs control the milling cutter to mill the two side edges of the U-shaped notch and the upper part of the arc-shaped connecting surface; And f, after the milling cutter removes the U-shaped notch burr on one side, the flywheel casting piece horizontally rotates by 180 degrees. According to the deburring method, the traditional tooling is abandoned for positioning in a mode of a central hole and an outer circular surface, instead, a fixed positioning block is adopted for positioning the arc-shaped connecting surface of the U-shaped notch of the flywheel casting piece, so that the positioning surface and the processing surfaceare the same, So as to effectively avoid the defect of dislocation caused by different positioning surfaces and processing surfaces in the prior art.

Description

technical field [0001] The invention belongs to the field of flywheel manufacturing, in particular to a method for deburring flywheel castings. Background technique [0002] The flywheel is a widely used part, which is first formed by casting and then deburred by machining. Such as figure 2 The flywheel shown is a rotary structure, and a U-shaped notch A1 is cast on both sides of the flywheel body A. The two sides of the U-shaped notch A1 and the top of a connecting arc surface need to be milled and deburred. At present, the entire outer circular surface or central hole of the flywheel body A is generally used for positioning, and then the two sides of the U-shaped notch A1 and the top of a connecting arc surface are milled. However, since the flywheel body A itself is a casting, the casting accuracy of the green body is relatively low, and milling after positioning the entire outer circular surface of the flywheel body A or the center hole will easily lead to misalignment...

Problems solved by technology

However, since the flywheel body A itself is a casting, the casting accuracy of the green body is relatively low, and milling after positioning the entire outer circular surface of the flywheel body A or the center hole will easily lead to misalignment between the milling part and the lower part of the U-shaped notch A1, thereby failing to achieve Processing requirements, this difficult problem has been puzzling those skilled in the art
