Problems solved by technology

[0002] The processing of many thin-walled workpieces will reduce the processing quality of the parts due to the vibration of the parts during the processing, resulting in dimensional errors or deformation, or even scrapping
Especially in the processing of flexible screens, the flexible screen uses plastic as the base material, which has an inner cavity, and the structure of the inner cavity is weak, and there is a flexible silicone part on the flexible screen, which is used to bury the antenna, making the material of the product complex. Therefore, the processing of flexible screens increases the difficulty of CNC processing and surface treatment in subsequent processes
[0003] In the traditional technology, for weak products such as flexible screens, because the structure of the product is a cavity structure, and the shape of the cavity is different, the product is generally sucked by vacuum, but the vacuum suction tube cannot be inserted into the cavity of the product, and the product There is a gap between the product and the vacuum gripper, and the side wall of the product is made of soft plastic, the product will give way during processing, which makes the product size deviate and the surface finish does not meet the requirements

Abstract

The invention relates to a stabilizing method for machining a cavity-type thin-walled part. The stabilizing method comprises the following steps that the cavity-type thin-walled part is provided witha cavity, a shaping clamp is disposed in the cavity, and a gap is arranged between the cavity-type thin-walled part and the shaping clamp; and the gap is filled with filler to obtain an assembly, theassembly is placed in a temperature furnace and heated to 50 DEG C-65 DEG C and cooled to a room temperature, the shaping clamp is taken out, and a cavity-type thin-walled part with a filling member is obtained. According to the stabilizing method for machining the cavity-type thin-walled part, the filling member is manufactured by filling the cavity-type thin-walled part with the filler, the strength of the inner wall of the cavity thin-walled part is strengthened by the filling member, and a product is prevented from cutter relieving during machining; and the appearance and size of the machined product can meet production requirements.
