Example Embodiment

[0017] A deformation control method in the processing of double-sided multi-rib structure parts, including the following steps:

[0018] 1) Use tooling to clamp the part blanks;

[0019] 2) Just see the inner layer of the new metal for the milling single-sided datum;

[0020] 3) Turn the parts over, use vacuum suction and external tooling to clamp the parts;

[0021] 4) The web and sides are processed on the front, leaving a small margin or directly processed in place, and the rib height is not processed;

[0022] 5) Remove vacuum adsorption and external tooling, such as figure 1 As shown, in the natural state, the amount of deformation of the upper surface part is removed 1;

[0023] 6) After turning over, use vacuum suction and external tooling to clamp the parts again, and perform rough machining and finishing on the reverse side in turn until the part size is processed;

[0024] 7) Turn over again, use vacuum adsorption and external tooling to clamp the parts, mill the front ribs to t...

Abstract

The invention relates to a deformation controlling method for machining a double-side multi-rib structural part. The method comprises the following steps of: 1) clamping a part blank by adopting a tool; 2) milling a single side reference till a new metal inner layer appears; 3) turning over the part, and clamping the part by using vacuum adsorption and an external tool; 4) machining a web plate and a lateral surface on the front side, and reserving low allowance or directly machining in place, wherein ribs are not machined in height; 5) removing the vacuum adsorption and the external tool, and removing the deformation of the upper surface part in a natural state; 6) turning over and then clamping the part by using the vacuum adsorption and the external tool again, and performing rough machining and finish machining on the reverse side sequentially till the size of the part is achieved; and 7) turning over again, clamping the part by using the vacuum adsorption and the external tool, milling the ribs on the front side until the height is appropriate, and performing finish machining till the size of the part is achieved. According to the method, the deformation of the part is controlled by adopting an internal stress counteraction method in the part machining process, so that the machining period is shortened, and the quality of the part is improved.

Description

technical field [0001] The invention relates to a deformation control method in the processing of double-sided multi-rib structural parts, which belongs to the field of mechanical processing. Background technique [0002] There are mainly two types of deformation process methods in the original control of double-sided multi-reinforced structural parts processing: [0003] 1) The method of multiple turning over is: after double-sided milling benchmark, through rough machining-turning-rough machining-turning-semi-finishing-turning-semi-finishing-turning-finishing-turning- Finishing, in this way, the method of repeatedly turning over to remove the allowance removes the deformation of the part. After each turning over, the external clamping force is used to offset the deformation of the part. Its disadvantages are: the biggest disadvantage of multiple turning over is that the processing cycle is too long, the labor intensity of workers is too high, and the processing benchmark ...
