At present, when the outer surface of the middle frame 2 is machined, multiple cutters are generally required to be customized and completed together, the multiple cutters are combined together to adjust a road to ensure smooth transition of curved surfaces, but the machining mode is complex in programming and long in machining time, and once a certain cutter is damaged in the machining process, subsequent machining processes are affected, so that the optimal machining scheme can be that one cutter is adopted to machine the multiple curved surfaces on the outer surface of the middle frame 2. Specifically, the curvature of the second curved surface is partially matched with the curvature of the first curved surface, and the curvature of the third curved surface is partially matched with the curvature of the first curved surface. Through the connection of third curved surface, can realize the smooth transition between first curved surface and the second curved surface, if adopt same cutter to accomplish the processing of first curved surface, second curved surface and third curved surface, its course of working can be: the first side wall 22 of the middle frame 2 may be machined first, and since the height of the first side wall 22 is higher than that of the second side wall 21, after the machining of the outer surface of the first side wall 22 is completed, the cutter may start to descend at a constant speed or at a constant acceleration for a preset distance, and then the outer surface of the second side wall 21 is machined in a straight-forward manner, and the outer surface of the second side wall 21 may be machined in a straight-forward manner during the descending process of the cutter. For realizing above-mentioned course of working, the cutting part that is used for processing of cutter can be the curve sword, and for adopting same cutter to process the surface of center 2 in succession, the setting of each curved surface can be: the curvature of the second curved surface is matched with the curvature of the first curved surface partially, and the curvature of the third curved surface is matched with the curvature of the first curved surface partially, namely the first curved surface, the second curved surface and the third curved surface can be suitable for processing the same cutter.

The specific arrangement of the top and bottom surfaces of the middle frame 2 is not particularly limited herein.
Example two
In the prior art, when processing an intermediate frame of an electronic device such as a mobile phone, in order to obtain an intermediate frame 2 meeting design requirements, the following two machining schemes are generally adopted: (1) respectively milling the outer surfaces of the first side wall, the second side wall and the connecting part of the middle frame 2 blank and the joint of the surfaces by using a plurality of vertical milling cutters; (2) and (3) customizing a special ball-end milling cutter, and processing each outer surface of the middle frame 2 by using one ball-end milling cutter at one time.
With both of the aforementioned machining solutions, there are respective disadvantages: (1) in the first scheme, when a plurality of vertical milling cutters are adopted to mill the outer surfaces of the first side wall 22, the second side wall 21 and the connecting part 23 and the joints of the surfaces, smooth transition of the milling cutters at the joints needs to be ensured during processing, so that machining program parameters need to be adjusted according to tolerance characteristics and wear conditions of the replaced cutters, the debugging period and the machine processing center have long downtime, and once one cutter is damaged in the processing process due to the fact that furniture is fragile, the subsequent processing process can be influenced, the processing time is delayed, and the processing cost is greatly increased; (2) in the second scheme, a ball-end milling cutter processing mode is adopted, and the cost of the customized ball-end milling cutter is high; in addition, when the ball end mill machines the outer surfaces of the first side wall 22, the second side wall 21 and the connecting portion 23, three-axis linkage is required, and machining programming is complicated.
As shown in fig. 6, a second embodiment of the present invention provides a processing tool for processing the electronic device, including:
the surface of the milling part 1 is provided with at least one milling tooth 11, and the edge part of the milling tooth 11 is a continuous curve edge 12 and is used for processing a first curved surface, a second curved surface and a third curved surface.
Based on the method for processing the middle frame 2 of the electronic device in the prior art, in order to avoid the disadvantages of the two schemes, the processing tool proposed in this embodiment only uses one tool, and includes the milling portion 1 for processing the middle frame 2 of the electronic device, the outer surface of the milling portion 1 is provided with at least one milling tooth 11, specifically, as shown in fig. 7, a plurality of milling teeth 11 circumferentially distributed on the surface of the milling portion may be provided, and the processing tool may further include a tool holder for mounting the milling portion 1. When the milling part 1 rotates around the rotation shaft, the milling teeth 11 also rotate along with the milling part, and the blade parts of the milling teeth 11 can process the set surface on the blank. In order to realize the processing of the first curved surface, the second curved surface and the third curved surface by the edge part of the milling tooth 11, the edge part of the milling tooth 11 can be set as a continuous curved edge 12, and the curved edge 12 is a concave curve relative to the milling part 1, and in order to realize the continuous processing of the first curved surface, the second curved surface and the third curved surface connecting the first curved surface and the second curved surface, the curvature of the curved edge 12 can be respectively matched with the curvatures of the first curved surface, the second curved surface and the third curved surface.
Specifically, the process of machining the middle frame of the electronic device by using the milling part may be as follows: the milling part 1 rotates around a rotating shaft of the milling part, a middle curve section of a curve edge 12 of a tooth cutting 11 mills a first curved surface of a first side wall 22 of a middle frame of the mobile phone, namely when the first curved surface is machined, a moving track of a middle point of the curve edge 12 is superposed with a contour center line AA of the first curved surface; when the curved edge 12 runs to the connecting part 23 where the first curved surface is connected with the second curved surface of one second side wall 21, the milling part 1 moves downwards along the rotating shaft of the milling part 1 at a constant speed or constant acceleration, meanwhile, the milling part 1 moves relative to the middle frame 2 of the electronic equipment at a plane vertical to the rotating shaft according to a preset curve, and in the process that the milling part 1 moves downwards, the third curved surface of the connecting part 23 is milled by the curved edge 12; after the third curved surface is machined, the milling part 1 stops moving downwards along the self rotary shaft, but machines the second curved surface of the second side wall 21 according to a preset track, at the moment, the middle curved section of the curved blade 12 of the tooth cutting 11 still mills the second curved surface, namely, when the second curved surface is machined, the moving track of the middle point of the curved blade 12 is superposed with the contour center line AA of the second curved surface, but because the height of the first curved surface is higher than that of the second curved surface, the ranges of the middle curved sections of the curved blade 12 corresponding to the first curved surface are different when the first curved surface and the second curved surface are machined, and the machining range of the middle curved section of the curved blade 12 corresponding to the first curved surface is larger than that of the second curved surface. When the milling part 1 runs to the connecting part 23 where the second curved surface of the second side wall 21 and the first curved surface of the other first side wall 22 meet, the milling part 1 moves at a constant speed or at a constant acceleration along the rotation axis of itself, and moves in a plane perpendicular to the rotation axis according to a predetermined curve relative to the middle frame of the electronic device, and the following process is the same as above. Similarly, when the other two connecting portions 23 are machined, the milling portion 1 repeats the above-described operation.
In the above process, the curve segment of the curved edge 12 corresponding to the third curved surface is changed with the up and down displacement of the milling part 1, and the curve segment of the curved edge 12 corresponding to the first curved surface and the second curved surface is always the curve segment located in the middle, and the difference is that the ranges of the curve segments are different.
The second embodiment of the present invention provides a processing tool, which can be used for processing the middle frame of the electronic device, but is not limited thereto, and can also be used for processing other smooth surfaces with continuous curved surfaces. The cutting parts are provided with the continuous curved edges, and the milling teeth rotate along with the cutting parts when the cutting parts rotate around the rotating shafts of the cutting parts, so that the continuous processing of the curved edges on the first curved surface, the third curved surface and the second curved surface can be realized, the processed first curved surface, the processed third curved surface and the processed second curved surface can be ensured, and the joints of the curved surfaces are smooth curved surfaces, the matching precision among various cutters is not required to be adjusted in an adaptive manner as in the prior art, and the texture or trace generated at the cutter joint by the processing of a plurality of cutters is avoided; by adopting the processing tool, the movement of the cutting part in the axial direction of the rotating shaft and the movement of the milling cutter in the plane vertical to the rotating shaft are only controlled in the machining process, and the method is suitable for the mass production of the middle frame of the electronic equipment; and the processing method of the processing tool is simple, and compared with a ball end milling cutter, the processing tool provided by the embodiment has relatively low use cost.
Specifically, the curvature of the first curved surface may match the curvature of the curved edge 12, the curvature of the second curved surface may match the curvature of the curved edge 12, and the curvature of the third curved surface may match the curvature of the curved edge 12. Specifically, the curve blade 12 as described above corresponds to a curve segment for machining the first curved surface and the second curved surface which is always a curve segment in the middle, and the difference is that the range of the curve segment as described above is different, as shown in fig. 7, the range of the curve segment of the curve blade for machining the first curved surface may be aa curve segment, as shown in fig. 8, the range of the curve segment of the curve blade for machining the second curved surface may be bb curve segment, the range of aa curve segment is greater than the range of bb curve segment, the curvature of bb curve segment is greater than the curvature of aa curve segment, so that the curvature of the first curved surface may match the curvature of aa curve segment, the curvature of the second curved surface may match the curvature of bb curve segment, although the curve blade 12 corresponds to a curve segment for machining the third curved surface which varies with the upward and downward displacements of the milling portion, and the curvature of the third curved surface still matches the curvature of a certain curve segment of the curve blade 12, i.e. matching the curvature of the curved edge 12.
In particular, the curvilinear edge 12 is symmetrical about its contour center point. The curved blade 12 is used for processing a first curved surface, a second curved surface and a third curved surface, the curved sections of the curved blade 12 corresponding to the processing of the first curved surface and the second curved surface are curved sections which are always located in the middle, and the first curved surface and the second curved surface can be curved surfaces which are symmetrical about the center line of the contour, so that the curved blade 12 can be set to be a curve which is point-symmetrical about the center line of the contour in order to facilitate the milling processing of the first curved surface and the second curved surface.
The milling part 1 can be arranged in various specific forms, the milling part 1 comprises a main body part 13, the milling teeth 11 are arranged on the outer peripheral surface of the main body part 13, and particularly, the main body part 13 can be arranged in a cylindrical shape; the milling teeth 11 are arranged on the surface of the body portion 13 and the distance from each point on said curved edge 12 of the milling teeth 11 to the surface of the body portion 13 varies smoothly.
Alternatively, as shown in fig. 6, the main body 13 may be further configured to: the curvature of the contour curve of the surface of the body portion 13 matches the curvature of the curved edge 12; the milling teeth 11 are arranged on the surface of the body portion 13, and the distances from each point on the curved edge 12 to the surface of the body portion 13 are equal. In this case, a mounting portion may be provided on the surface of the body portion 13, where the milling tooth 11 may be detachably mounted, achieving fixation with the body portion 13; i.e. the milling tooth 11 is a removable insert.
The milling teeth 11 may be straight teeth (as shown in fig. 6) or helical teeth, and preferably helical teeth are used. The milling cutter face of the helical milling tooth 11 can facilitate the discharge of cutting chips along the front face of the milling tooth 11; moreover, the helical milling teeth 11 are point contacts when the middle frame blank is machined, and the impact force applied to the milling machine tool can be reduced.
Preferably, the curved edge 12 in this embodiment may be a spline curve segment. In a particular application, the spline curve segment may be a bezier curve. In other embodiments, the curved edge 12 may be a curved segment of various widely used curves.
