Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of workpiece fixture equipment, in particular to an annular workpiece processing fixture structure which can be tilt-adjusted. Background Art
[0002] Thin-walled annular workpieces are the most common parts in the machinery industry. They are light in weight, save materials, and have compact structures. Traditional processing methods generally use roughing and finishing separately. After roughing, aging treatment is used to eliminate the internal stress of the workpiece. Then, during finishing, soft claw clamping is used to ensure the processing requirements of general workpieces.
[0003] Usually, the processing technology of thin-walled annular workpieces is to use the inner ring or outer ring of the thin-walled workpiece as the positioning reference after rough machining, and use fine turning, grinding and other methods to process the relative annular surface, and then use the relative processed annular surface as the positioning reference to process the original positioning surface. After processing, it is required to ensure that the roundness and concentricity of the inner and outer rings are within the tolerance. Existing auxiliary tooling such as three-jaw chucks and four-jaw chucks, whether using the inner ring or outer ring of the thin-walled workpiece as the positioning reference, will cause the annular workpiece to deform when the clamping force is too large due to the poor rigidity and weak strength of the thin-walled annular workpiece; and when the clamping force is too small, the annular workpiece cannot be effectively fixed, and it is very easy to deform during CNC milling, which increases the shape and position errors of thin-walled parts, making it difficult to ensure the processing quality of thin-walled annular workpieces, and it is impossible to adjust the inclination according to the use process.
