Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy parts processing technology, specifically to an aluminum alloy thin-walled frame part. Background Technology

[0002] Thin-walled aluminum alloy frames are common mechanical parts. These parts are used in environments where sufficient strength is guaranteed while minimizing overall mass, typically when there are strict requirements for the overall weight of the equipment. However, due to processing stress and the material itself, these parts often experience uncontrollable deformation during processing.

[0003] The deformation of general parts during machining mainly comes from clamping forces and machining stresses. Therefore, when high precision is required, it is necessary to reduce or even eliminate these stresses. Furthermore, due to the inherent low rigidity of thin-walled parts, they are more prone to deformation and tool deflection during production compared to other structural parts. The probability of cutting deformation caused by the cutting forces experienced by the workpiece during clamping is extremely high. Therefore, in CNC machining, it is essential to strictly control the material removal rate.

[0004] Excessive material removal rates often lead to overheating during machining, increasing material stress and causing deformation. Therefore, precise control of machining parameters, such as cutting speed, feed rate, and depth of cut, is crucial.

[0005] Therefore, the utility model proposes to provide an aluminum alloy thin-walled frame part. Utility Model Content

[0021] Figure 1 This is a structural schematic diagram of an aluminum alloy thin-walled frame part provided in an embodiment of this utility model. See also... Figure 1-2 The part may include a frame body 1 and a plurality of process tables 2 distributed sequentially at intervals along the circumference of the frame body 1, each process table 2 having a mounting through hole 201 along its thickness direction.

[0022] In the above embodiment, the process table 2 is protruding, extending circumferentially along the frame body 1. The frame body 1 and the process table 2 are integrally formed, and the frame body 1 has a ring-shaped structure. The lower end face of the process table 2 is flush with the lower end face of the frame body 1. This process table 2 ensures the dimensional accuracy of the product, provides fast processing speed, reduces the number of clamping operations, facilitates quick and easy alignment, and is convenient to use.

[0023] This type of aluminum alloy thin-walled frame part has a side wall frame thickness of only 3mm and an overall size of 950*550*40mm. The flatness tolerance requirement is +0.10. The specific processing steps are as follows: (1) Press the material on the worktable of the CNC machine tool, remove the center large material and mill one side, use the machining surface as the reference probe to find the center line of the part and rough machine the convex surface and inner cavity, leaving a 2mm allowance; (2) After rough machining is completed, loosen the pressure plate, continue to press it onto the machine tool with a clamping force of only 35N, using the smooth surface as the reference, and then proceed directly to finish machining after aligning with a dial indicator. (3) Turn over and continue pressing the material on the CNC machine tool worktable. Using the boss surface as a reference, use the probe to align the center line of the part and rough machine the outer shape and inner cavity of the inner cavity, leaving a 2mm allowance. (4) After rough machining on the CNC machine tool, loosen the pressure plate, continue to press it onto the machine tool with a clamping force of only 35N, using the smooth surface as the reference, and then proceed directly to finish machining after aligning with a dial indicator.

[0024] The clamping force is analyzed and calculated to determine the relationship between clamping force and cutting force, making the structure more stable; the semi-finishing method of the workpiece is eliminated, thereby effectively reducing the workpiece's press-fit deformation. The purpose is to reduce stress deformation of thin-walled frame parts during machining and to reduce press-fit deformation by adding a process table, thus ensuring the final machining accuracy.
