Fixing device for aluminum thin-wall part processing and processing method of fixing device

Abstract

The invention discloses a fixing device for aluminum thin-wall part processing and a processing method of the fixing device. The processing method comprises the following steps: S1, preparing a filling agent which comprises the following components in percentage by mass: 55-60% of talcum powder, 25-33% of a polyamide adhesive or an ethylene-vinyl acetate copolymer adhesive or butter, 7-18% of paraffin or vaseline and 2-4% of calcined gypsum powder. Compared with gypsum and paraffin filling agents, the filling agent has the advantages that the breakage rate is obviously reduced; and compared with the traditional gypsum or paraffin filling agent, the filling agent has the advantages that the filling agent can be better adhered to the surface of an aluminum thin-wall part and cannot be separated from the aluminum thin-wall part due to vibration, so that the aluminum thin-wall part is prevented from being easily broken in the processing process, the problem that the filling agent is not easy to peel off the surface of an aluminum badminton due to drying is avoided, and the problem of deformation of the thin-wall part is avoided.

Description

technical field [0001] The invention relates to the technical field of processing aluminum thin-walled parts, in particular to a fixing device for processing aluminum thin-walled parts and a processing method thereof. Background technique [0002] In the process of processing thin-walled aluminum parts, it is easy to cut and damage the thin-walled parts through machining, especially when the wall thickness reaches below 0.5mm. Special fixtures are used to fix thin-walled parts. Since the workpiece and the fixture cannot be fully fitted, a slight gap will increase the probability of damage to the thin-walled part. Usually, fillers are attached to the surface of the thin-walled part to reduce the breakage rate. [0003] The more common filler is gypsum. Gypsum is characterized by strong fluidity. After mixing with water, it flows quickly to the space to be filled in a liquid state, and the drying time is relatively fast. However, gypsum has no adhesion to the workpiece. When ...

Problems solved by technology

[0003] The more common filler is gypsum. Gypsum is characterized by strong fluidity. After mixing with water, it flows quickly to the space to be filled in a liquid state, and the drying time is relatively fast. However, gypsum has no adhesion to the workpiece. When When the tool cuts the workpiece, once the vibration is large, the workpiece and the gypsum will be separated; in addition, paraffin is used as a filler. The adhesion of paraffin is better than that of gypsum, but the adhesion cannot meet the processing requirements. Vibrates and separates from the workpiece, resulting in damage to the workpiece. Therefore, the invention provides a fixing device for processing aluminum thin-walled parts and a processing method thereof
