[0002] In the manufacturing process of mobile phones and other electronic devices, workpieces such as mobile phone shells need to be sandblasted. At present, before the workpiece processing is completed and the sandblasting operation begins, the flatness of the workpiece needs to be shaped so that its flatness is within the specified flatness tolerance, and then the shaped workpiece is sandblasted to perform external and internal surface sandblasting.
[0003] When performing sandblasting operations, the existing sandblasting jig first fixes the workpiece with a U-shaped titanium clip, and then rotates the clamped workpiece and turns it over to sandblast the inner surface of the workpiece. When clamping the workpiece, the relevant staff is required to press the U-shaped titanium clip hard, and then release it after the workpiece is clamped, so that the U-shaped titanium clip rebounds and clamps the workpiece. In the long run, multiple presses on the U-shaped titanium clip will cause the U-shaped titanium clip to deform and fail, affecting the effect of fixing the workpiece. When sandblasting the inner surface of the workpiece, since the sand particles are concentrated in the inner cavity of the workpiece, the workpiece is too heavy, and the U-shaped titanium clip has a poor fixing effect on the workpiece, it is easy for the workpiece to fall, causing workpiece abnormalities and high processing costs.

In addition, each operation to fix the workpiece requires the relevant staff to press hard, which has high labor intensity and high labor costs.
[0053] In view of this, the present application provides a sandblasting jig to solve the problems that the existing sandblasting jig has a poor fixing effect on the workpiece, has a high labor intensity when fixing the workpiece, and has a high processing cost.

[0059] In this embodiment, the rotating shaft 32 can drive the latch 33 to rotate counterclockwise within a preset angle range relative to the positioning rod 31 , so that the latch 33 moves into the limiting groove 313 , thereby locking the cover plate 10 on the bottom plate 20 .
[0060] In this embodiment, the rotating shaft 32 can also drive the latch 33 to rotate clockwise relative to the positioning rod 31 within a preset angle range, so that the latch 33 is disengaged from the limiting groove 313, thereby separating the cover plate 10 from the bottom plate 20. In this embodiment, the preset angle can be 90 degrees.
[0061] In the above embodiment, the cover plate 10 and the bottom plate 20 are locked by the locking mechanism 30, thereby fixing the workpiece, preventing the workpiece from falling off the bottom plate 20 during the sandblasting process and preventing the workpiece from being mechanically damaged, reducing the occurrence of abnormalities, improving the processing yield, and reducing production costs. In addition, the locking operation is achieved only by rotating the rotating shaft 32, which is simple, time-saving and labor-saving, reducing labor costs, and improving processing efficiency.

The shielding block 38 is installed on the side of the cover plate 10 opposite to the bottom plate 20. The rotating shaft 32 passes through the shielding block 38 and the cover plate 10 in sequence.
[0074] In the above embodiment, by installing the blocking block 38 , sand particles can be prevented from entering the rotating hole 11 during the sandblasting process, thereby ensuring the normal use of the locking operation of the locking mechanism 30 .
[0075] In one embodiment of the present application, the locking mechanism 30 further includes a handle 39 . The handle 39 is installed at the second end 322 .
[0076] In the above embodiment, by installing the handle 39 on the rotating shaft 32, it is convenient for relevant staff to rotate the rotating shaft 32, which saves time and effort, reduces labor intensity, and improves processing efficiency.
