[0025] The present invention will now be described in conjunction with specific embodiments.

[0026] Example 1, as Figures 1 to 4 As shown, a multi-position deburring fixture for the front and back of a mobile phone frame includes a fixture base 1 arranged horizontally, and the upper surface of the fixture base 1 is provided with a plurality of frame placement areas 2 arranged sequentially from left to right.

[0027] Among them, such as Figure 1 and Figure 4 As shown, the fixture base 1 has vertical through holes 3 in each of the middle frame placement areas 2, which are corresponding to the burr removal position on the reverse side of the mobile phone middle frame 10.

[0028] Furthermore, such as Figures 1 to 4 As shown, the multi-clamping front and back deburring fixture for the mobile phone frame also includes a fixture cover plate 4. The fixture cover plate 4 is located on the upper side of the fixture base 1. The fixture cover plate 4 has vertical through holes 5 corresponding to the front deburring positions of the mobile phone frame 10 in each of the middle frame placement areas 2 of the fixture base 1.

[0029] Furthermore, such as Figure 1 , Figure 2 as well as Figure 4 As shown, the clamp base 1 is equipped with a base fastener 6, and the clamp cover plate 4 is equipped with a cover plate fastener 7; when the clamp cover plate 4 is in the closed position, the cover plate fastener 7 is engaged with the base fastener 6.

[0030] It should be explained that the fixture base 1 and fixture cover plate 4 in this embodiment are aluminum alloy parts; of course, the above materials do not constitute a limitation on this embodiment, that is, the fixture base 1 and fixture cover plate 4 in this embodiment can also be made of other materials, such as stainless steel.

[0031] And also, such as Figure 1 As shown, the upper surface of the fixture base 1 is provided with six middle frame placement areas 2 arranged sequentially from left to right; of course, the above number does not constitute a limitation on this embodiment, that is, the fixture base 1 of this embodiment can be provided with five, seven, eight or other numbers of middle frame placement areas 2.

[0032] In the first embodiment of this mobile phone frame multi-clamping front and back deburring fixture, multiple mobile phone frames 10, which have been CNC precision milled on the front and CNC precision milled on the back, are placed sequentially in the frame placement area 2 of the fixture base 1. After the multiple mobile phone frames 10 are placed in the fixture base 1, the fixture cover 4 is closed. During this process, the cover fastener 7 of the fixture cover 4 is engaged with the base fastener 6 of the fixture base 1, so that the fixture cover 4 remains closed and the fixture cover 4 presses and secures the multiple mobile phone frames 10 placed in the frame placement area 2. The system is then used to clamp and fix multiple mobile phone frames 10 together. During the deburring operation, the fixture base 1 can be clamped by a robotic arm. When deburring is required on the front of the mobile phone frame 10, the fixture cover plate 4 faces upward. At this time, the deburring operation on the front of the mobile phone frame 10 can be performed through the cover plate clearance hole 5 of the fixture cover plate 4. When deburring is required on the back of the mobile phone frame 10, the fixture base 1 faces upward. At this time, the deburring operation on the back of the mobile phone frame 10 can be performed through the base clearance hole 3 of the fixture base 1.

[0033] It should be emphasized that the multi-clamping front and back deburring fixture for the mobile phone mid-frame in this embodiment can achieve deburring of the front side of the mobile phone mid-frame 10 through several cover plate clearance holes 5 opened on the fixture cover plate 4, and can achieve deburring of the back side of the mobile phone mid-frame 10 through several base plate clearance holes opened on the fixture base 1. That is, the multi-clamping front and back deburring fixture for the mobile phone mid-frame in this embodiment can meet the deburring of the front and back sides of the mobile phone mid-frame 10 with one clamping. Compared with the prior art, the multi-clamping front and back deburring fixture for the mobile phone mid-frame in this embodiment can effectively improve the efficiency of deburring of the mobile phone mid-frame 10.

[0034] In summary, the multi-clamping front and back deburring fixture for mobile phone mid-frames in this embodiment has the advantages of novel structural design and convenient use, and can be applied to both front and back deburring of mobile phone mid-frames 10.

[0035] Example 2, as Figure 2 and Figure 4 As shown, the difference between this embodiment 2 and embodiment 1 is that the rear edge of the fixture base 1 is hinged to the rear edge of the fixture cover plate 4 by a number of hinges 8 arranged sequentially from left to right.

[0036] When the clamp cover plate 4 is opened or closed relative to the clamp base 1, the clamp cover plate 4 is flipped relative to the clamp base 1 via the hinge 8, which improves the convenience of opening and closing the clamp cover plate 4.

[0037] Example 3, as Figure 1 As shown, the difference between this embodiment 3 and embodiment 2 is that: the front end of the clamp base 1 is equipped with two symmetrical and spaced-apart base fasteners 6, and the front end of the clamp cover plate 4 is equipped with two symmetrical and spaced-apart cover plate fasteners 7.

[0038] When the clamp cover plate 4 is in the closed position, each cover plate fastener 7 is engaged with the corresponding base fastener 6.

[0039] Example 4, as Figure 1 As shown, the difference between this embodiment four and embodiment one is that: at least two spaced middle frame positioning posts 9 are installed on the upper surface of the fixture base 1 in each middle frame placement area 2.

[0040] When the mobile phone mid-frame 10 is placed in the mid-frame placement area 2 of the fixture base 1, this embodiment four uses the mid-frame positioning post 9 to position the mobile phone mid-frame 10 so as to ensure that the mobile phone mid-frame 10 can be accurately placed in the mid-frame placement area 2.

[0041] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
