Deburring tool for flywheel casting part

Abstract

The invention discloses a deburring tool for a flywheel casting part. A fixed positioning block is of a U-shaped structure; the surfaces of the sides, close to a moving pressing block, of the two lateral sides of the fixed positioning block are arc surfaces; the two arc surfaces are used for positioning an arc connecting surface of a U-shaped notch of the flywheel casting part; a moving positioning block is arranged outside the fixed positioning block; the moving positioning block is of a U-shaped structure; the left surfaces of the two lateral sides of the moving positioning block are inclined surfaces; and the two inclined surfaces form a splay shape toward the moving positioning block. By being adopted that the fixed positioning block positions the arc connecting surface of the U-shapednotch of the flywheel casting part and the moving position block positions the connection position between an excircle surface of the flywheel casting part and the lateral side of the U-shaped notch,the deburring tool can realize the automatic centering; an air cylinder drives the moving pressing block to press the top surface of the flywheel casting part so that the flywheel casting part is positioned and pressed and the positioning surface and the processing surface are the same; and therefore, the misalignment defect of the positioning surface and the processing surface caused when the positioning surface and the processing surface are not the same in the prior art is effectively avoided.

Description

technical field [0001] The invention belongs to the field of clamps, and in particular relates to a deburring tool for a flywheel casting. 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 betw...

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
