Thin-walled disc-shaped casting anti-shock knife anti-deformation processing tooling

Abstract

The invention provides a chattering and deformation prevention processing tooling for a thin-wall disc casting. The chattering and deformation prevention processing tooling comprises a base, connecting rods, fixing blocks, universal joints and six fixing holes formed in the edge of the thin-wall disc casting, wherein connecting holes are formed in the fixing blocks; the two adjacent fixing holes are in a group and correspond to positions of the two connecting holes in the corresponding fixing block; the universal joints are positioned between the fixing holes and the connecting holes; and the connecting rods sequentially penetrate through the fixing holes, the universal joints and the connecting holes in the fixing blocks to connect the thin-wall disc casting with the base. According to the chattering and deformation prevention processing tooling for the thin-wall disc casting provided by the invention, the thin-wall disc casting is horizontally fixed through adding supporting points and the universal joints, three points are fixed to guarantee that the surfaces of a workpiece are on the same plane based on the three-point self centering principle, and the deformation of the workpiece is prevented.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to an anti-shock knife anti-deformation processing tool for thin-walled disc-shaped castings. Background technique [0002] Castings need to be ground, polished and deburred after casting. When thin-walled disc-shaped castings are subjected to grinding, polishing and deburring, the wall thickness of thin-walled disc-shaped castings is relatively thin and the diameter is relatively large. When the traditional tooling is fixed, the processing surface is not flat, and the cutting amount of the cutting tool will be large and small during the cutting process. Therefore, the force generated between the workpiece and the cutting tool will also change irregularly, causing the shaking of the cutting tool; in addition, due to the thickness of the workpiece Thin and prone to deformation during processing.

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: In order to overcome the deficiencies in the prior art that the tool is prone to vibration and the workpiece is easily deformed, the present invention provides a thin-walled disc-shaped casting anti-vibration tool deformation-resistant processing tool, which adopts additional support points and universal The shaft joint realizes the horizontal fixation of the thin-walled disc-shaped casting. Based on the principle of three-point self-centering, three-point fixation is used to ensure that the surface of the workpiece is on the same plane to prevent deformation of the workpiece.
