Problems solved by technology

[0002] At present, many parts of mobile phones, such as the back cover of the mobile phone, are formed by injection molding. After demoulding, the injection-molded parts can be taken out. However, the corners of the back cover of the mobile phone after demoulding usually have burrs Or burrs, when using or assembling these parts, it is first necessary to deal with the burrs or burrs, before polishing, the back cover needs to be clamped by a clamp, the existing clamping device is not good for the clamping effect of the mobile phone back cover , because it is necessary to grind the inside and outside of the shell separately during grinding, and the existing clamping device does not have the function of adjusting the angle or turning over, so it needs to be clamped and then polished in stages, which makes the process cumbersome and makes the grinding efficiency low. It is necessary to develop a conveniently adjustable fixture for clamping the back cover of a mobile phone

Embodiment 1

[0027] The mechanical manufacturing disclosed by the invention is convenient to adjust the fixing fixture, such as figure 1 As shown, it includes a base 1, an incomplete gear mechanism, a mobile phone cover clamping platform, and an angle adjustment mechanism. The base 1 is a hollow columnar structure with an open top. The first support shaft 3 is connected; the incomplete gear mechanism is arranged in the base 1, and the incomplete gear mechanism is connected with the lower end of the first support shaft 3 so as to drive the rotating plate 2 for intermittent circular motion; the mobile phone cover clamping platform includes The first support plate 4 that is arranged on the upper surface side of the rotating plate 2, the top of the first support plate 4 is movably connected with a placement plate 5 through a hinge, and the upper surface of the placement plate 5 is also provided with a mobile phone cover clamping structure; The adjustment mechanism includes a triangular prism s...

Embodiment 2

[0034] Further, on the basis of embodiment 1, as image 3 As shown, the incomplete gear mechanism includes a second motor 14 installed in the base 1, the output shaft of the second motor 14 is vertically upward and is connected with a driving gear 15, and a driven gear meshing with the driving gear 15 is also arranged in the base 1. Gear 16, the inner bottom of the base 1 is also provided with a second support shaft 17 for supporting the rotation of the driven gear 16, the lower end of the first support shaft 3 is fixedly connected with the upper end surface of the driven gear 16, and the second motor 14 is also connected to the controller connect. When the second motor 14 rotated, the second motor 14 drove the driving gear 15 of the incomplete gear mechanism to rotate. When the driving gear 15 rotated, the driven gear 16 meshed with it would rotate intermittently. When the driving gear 15 was adjusted After a certain speed, the driven gear 16 can drive the first support shaf...

Embodiment 3

[0036] Further, on the basis of embodiment 1, as Figure 4As shown, the mobile phone cover clamping structure includes a hollow installation groove 18 fixed on the upper surface of the placement plate 5, and the top of the placement groove 18 is provided with a horizontal guide rod 19, and the two ends of the guide rod 19 are respectively connected with the inner side walls of the placement groove 18. The guide bar 19 is also provided with a third slider 20 and a fourth slider 21 respectively. The surface is fixedly connected with the second fixed block 23 protruding from the installation groove 18, and the lower side of the third slider 20 is connected with the swing rod 25 through the inserted pin shaft 24, and the swing rod 25 is provided with a strip-shaped sliding structure. Hole 26, bearing pin 24 slides in sliding hole 26, and the midpoint place of swing lever 25 is rotated and is equipped with supporting rotating shaft 27, and the two ends of supporting rotating shaft ...
