Embodiment 1

[0033] Such as Figure 1-3 As shown, a mobile phone case magnetic clamping fixture includes: a base 1; a positioning plate 2, which is fixedly connected to the base 1, and at least a first positioning rod 21 and a positioning plate 2 are fixedly connected to the positioning plate 2 The second positioning rod 22, the upper surface of the positioning plate 2 conforms to the shape of the mobile phone case to be processed, and the horizontal connection line direction of the first positioning rod 21 and the second positioning rod 22 is parallel to the length direction of the positioning plate 2; The main body of the pressing plate 3 adopts a honeycomb structure, the honeycomb holes on the upper surface of the pressing plate 3 are open, the honeycomb holes on the lower surface of the pressing plate 3 are closed, and the upper part of the side wall of the pressing plate 3 is provided with a first groove, the first groove Transversely penetrate the honeycomb holes in the pressure plate...

Embodiment 2

[0040] The mobile phone case magnetic clamping jig further includes a rigid protective plate 5 installed between the pressing plate 3 and the positioning plate 2. The distance between the lower surface of the first permanent magnet block 211 and the upper surface of the positioning plate 2 is equal to the sum of the thickness of the mobile phone case, the thickness of the rigid protective plate 5 and the thickness of the pressing plate 3. The rigid guard plate 5 is used to increase the rigidity of the mobile phone case, so that the tool can use greater power and speed when processing the mobile phone case, thereby improving production efficiency. Since the rigid guard plate 5 is added in this embodiment, the height of the lower surface of the corresponding first permanent magnet block 211 from the upper surface of the positioning plate should be adjusted accordingly to the thickness of the mobile phone case and the rigid guard plate 5. The thickness is the sum of the thickness ...

Abstract

The invention relates to a mobile phone shell magnetic clamping fixture. The mobile phone shell magnetic clamping fixture comprises a base, a positioning plate, a pressing plate, a soft magnetic filler and a magnetic field generator, wherein the positioning plate is at least fixedly connected with a first positioning rod and a second positioning rod, and the upper surface of the positioning plateis matched with the shape of a mobile phone shell to be machined; a main body of the pressing plate adopts a honeycomb structure, honeycomb holes in the upper surface of the pressing plate are open, honeycomb holes in the lower surface of the pressing plate are closed, a first groove is formed in the upper part of the side wall of the pressing plate, and the first groove transversely penetrates through the honeycomb holes; the soft magnetic filler is granular and used for filling the honeycomb holes; and the magnetic field generator is located under the base, a magnetic field produced by the magnetic field generator covers an area of the positioning plate and the pressing plate. According to the mobile phone shell magnetic clamping fixture, the mobile phone shell is clamped through magnetic force, the mobile phone shell magnetic clamping fixture is fast, convenient and efficient in cleaning, local force adjustment can be conducted on the mobile phone shell, the force size of the mobilephone shell can be wholly adjusted, and the mobile phone shell can be assembled, disassembled and locked more easily.

Description

Technical field [0001] The invention relates to a clamping fixture, in particular to a magnetic clamping fixture for a mobile phone shell. Background technique [0002] During the mechanical manufacturing process, the device used to fix the phone case to be added is called a clamp. The use of clamps improves the efficiency and precision of mechanical manufacturing. With the development of science and technology, people's living standards continue to improve, and people's requirements are getting higher and higher, which has spawned more and more manufacturing fields that require high-precision requirements. The pursuit of high-precision products requires the use of various fixtures in many occasions. [0003] In order to pursue high-precision design fixtures, the requirements for fixture details are getting higher and higher. For special mobile phone cases or special processing requirements under many special circumstances, the force requirements of the mobile phone cases to be ...
