Description

Technical Field

[0001] The utility model relates to the field of LED waterproof box processing, in particular to a machine tool fixture for waterproof box processing. Background Art

[0002] LED display is a flat panel display, composed of small LED module panels, used to display text, images, videos and other information. LED display is widely used in commercial media, cultural performance market, stadiums, information dissemination, news release, securities trading, etc., which can meet the needs of different environments. In the process of outdoor display, LED display needs to be used with waterproof box. Some parts of the waterproof box are cast aluminum parts. After the casting is completed, the surface of the casting needs to be refined by CNC machine tools.

[0003] For example, the patent with authorization announcement number CN220407958U discloses an anti-deformation CNC machine tool clamp, including: a clamp seat; a clamping mechanism, which is arranged above the clamp seat; and a dustproof mechanism, which is arranged above the clamp seat; wherein the clamping mechanism includes a lead screw nut, and the lead screw nut is movably mounted on the inner wall of the clamp seat.

[0004] The above patent sets a lead screw nut, a first clamping block and a semi-circular ball.
