Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, in particular to a longitudinally clamping mobile phone middle frame fixture. Background Art

[0002] The frame of a mobile phone is the part that connects the front screen and the back cover of the mobile phone. It is also an important part to hold the mobile phone when using it. This requires that the molding precision of the mobile phone frame should be high, and the corners should be smooth and comfortable after molding. The mobile phone frame is made of metal, which usually includes irregular arc parts and chamfered parts connected to the mobile phone screen, and is formed by machine tool milling;

[0003] During the manufacturing process, the middle frame of the mobile phone needs to be milled. During the milling process, the middle frame of the mobile phone needs to be positioned first to facilitate the milling process of the mobile phone middle frame and to prevent the middle frame of the mobile phone from shaking during the milling process and requiring a clamp to fix it.

[0004] When processing the inner side of the mobile phone frame, the frame is generally placed on a flat plate, and horizontally placed cylinders are set on the flat plates around the frame. The cylinders push the outer side of the frame to position it. This positioning method causes the frame to have an upward degree of freedom, which may cause the frame to warp during positioning.

[0005] At the same time, in the prior art, when multiple mobile phone shells need to be supported in parallel, generally only the number of original workstations is increased, and the number of cylinders for each clamping is increased; it can be understood that originally one processing station requires four execution cylinders, and when two processing stations are required, eight cylinders are required; this is not only more costly, but also leads to tight assembly space on the workstation action table.

[0006] In order to solve the above problems, the utility model proposes a longitudinal clamping type mobile phone middle frame clamp to more accurately solve the technical problems mentioned in the above background technology.

[0007] The utility model is realized by the following technical solutions:

[0012] Furthermore, the limiting assembly includes a limiting pin; the limiting pin is fixedly arranged on the supporting horizontal plate; and at the same time, a limiting hole matching the limiting pin is arranged at the bottom of the mobile phone frame supporting tooling.

[0026] Please refer to Figure 1-Figure 5 The utility model proposes a longitudinal clamping type mobile phone middle frame fixture, comprising a support frame 1, a mobile phone frame supporting tool 2, a side clamping mechanism 3 and a middle clamping mechanism 4; the support frame 1 is used to be installed on a station for processing a mobile phone frame; a mobile phone frame supporting tool 2 is arranged on the top of the support frame 1, and the mobile phone frame supporting tool 2 is used to limit the mobile phone frame, which is convenient for processing the mobile phone outer frame; a side clamping mechanism 3 and a middle clamping mechanism 4 are arranged below the support frame 1; the side clamping mechanism 3 and the middle clamping mechanism 4 are used to clamp the mobile phone outer frame longitudinally;

[0027] In this embodiment, a plurality of mobile phone frame support fixtures 2 are arranged on the top of the support frame 1, and the following is introduced based on only two groups of mobile phone frame support fixtures 2; the two groups of mobile phone frame support fixtures 2 are arranged side by side on the top of the support frame 1; at the same time, in order to improve the limiting stability of the mobile phone frame support fixtures 2 and the support frame 1, a limiting component is arranged at the bottom of the support frame 1 and the mobile phone frame support fixture 2; a middle clamping mechanism 4 is arranged below the support frame 1 and between the two mobile phone frame support fixtures 2; a side clamping mechanism 3 is arranged below the support frame 1 and on one side of the outermost length edge of the mobile phone frame support fixture 2; the middle clamping mechanism 4 is used to clamp the two mutually adjacent longitudinal edges of the mobile phone frame arranged on the top mobile phone frame support fixture 2; the side clamping mechanism 3 is used to clamp the two outermost longitudinal (length) edges of the mobile phone frame on the mobile phone frame support fixtures 2 arranged in parallel;

[0028] like Figure 3 As shown, in this embodiment, the support frame 1 includes a support vertical plate 11, a support horizontal plate 12 and a support rib plate 13; the support vertical plate 11 is provided with a fixing hole 111, and the support vertical plate 11 is fixed to the mobile phone frame processing station through the fixing hole 111; the support horizontal plate 12 is arranged perpendicular to the support vertical plate 11; the support horizontal plate 12 and the support vertical plate 11 are also fixed by screws; a plurality of groups of support rib plates 13 are arranged in the right-angle space below formed by the support horizontal plate 12 and the support vertical plate 11, and two groups are given as an illustration in this embodiment; a through groove 131 is provided inside the support rib plate 13; in this way, the support rib plate 13 can further reduce weight and reduce costs while connecting and supporting the support vertical plate 11 and the support horizontal plate 12;

[0029] As an implementable embodiment, the limit assembly includes a limit pin 121; the limit pin 121 is fixedly arranged on the supporting horizontal plate 12; at the same time, a limit hole matching the limit pin 121 is arranged at the bottom of the mobile phone frame supporting tool 2; when the mobile phone frame supporting tool 2 is placed on the top of the supporting horizontal plate 12, the limit pin 121 can better limit the mobile phone frame supporting tool 2 to prevent it from shaking;
