Embodiment Construction

[0019] The technical solutions of the present invention will be further limited below in conjunction with the accompanying drawings and specific embodiments, but the scope of protection is not limited to the descriptions made.

[0020] Such as Figure 1-2 As shown, the machining method of a kind of frame parts provided by the present invention, the processed frame parts size is as follows figure 1 , the schematic diagram of the process block is as follows figure 2 .

[0021] The main steps include: (1) Rough milling of the front and back of the part, according to the machining accuracy, a process block is reserved at the through cavity of the part, and a margin of 0.5mm is left on one side of the other processing places; (2) The front and back of the part are finely milled respectively. The front and back sides of the rough milling part are clamped in a vise.

[0022] The operation of retaining the process block is as follows: the surface of the process block and the upper...

Abstract

The invention relates to the technical field of machining, in particular to a machining method for frame parts. The machining method comprises the following steps that the rough milling of the front and back surfaces of parts is performed, a process block at the part through cavity is reserved according to the machining precision, and a margin of 0.5 mm at the other machining positions is reserved; and the respective finish-milling of the front and back surfaces of the parts is performed. According to the method, by controlling machining allowance accurately, the parts are accurately and precisely milled; by reserving the process block, the deformation stress can be released during rough milling, the supporting effect can be achieved when inner depression and the surface of the frame are machined; and the product size is effectively guaranteed, the clamping is convenient, the pressure plate changing time is shortened, and the machining efficiency is improved. By adopting the machiningprocess method, the problem of deformation of frame parts is solved, the product quality is stable, the requirements of design drawings are met, and the product qualification rate and the machining efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a machining method for frame parts. Background technique [0002] Frame parts are common types in machining. Especially the box body parts made of 2A12-H112, which have the characteristics of large size, light weight and simple structure. Due to the structural characteristics of the parts, the parts are easily deformed during processing, and it is difficult to guarantee the dimensional tolerance and shape tolerance of the product, and cannot meet the design requirements. The main difficulties in processing this part are: (1) The shape of the part is large and there is a lot of allowance; (2) The thickness, flatness and surface quality of the part are high. The main difficulty in the processing of this type of parts is the deformation of the parts and the difficulty in clamping during the processing. [0003] The existing mechanical processing process of this type of frame pa...
