The utility model relates to a fixing device, belongs to the technical field of aluminum
veneer spraying, and particularly relates to a fixing device for hyperbolic aluminum
veneer spraying, which comprises a shell, a fixing block is fixedly connected in the shell, a threaded sleeve is slidably connected onto the fixing block, and the threaded sleeve is fixedly connected onto the fixing block. A supporting strip is fixedly connected to the threaded sleeve, a first sliding groove is formed in the shell, and a first sliding block is slidably connected into the first sliding groove. According to the hyperbolic aluminum
veneer fixing device, the curved surface of one side of a hyperbolic aluminum veneer is supported through cooperation of the sliding plate and the supporting block, the curved surface of the other side of the hyperbolic aluminum veneer is supported through cooperation of the fixing block, the threaded sleeve and the supporting strip, and therefore fixing of the hyperbolic aluminum veneer is completed, and follow-up spraying work is facilitated; and the distance between the two supporting blocks is adjusted, through cooperation of a
threaded rod, a threaded sleeve, a first
bevel gear, a rotating column and a second
bevel gear, the height of the supporting strips is adjusted so as to adapt to hyperbolic aluminum veneers of different sizes, and the practicability of the device is improved.
