The invention provides a worktable device used for
processing a board, capable of decreasing
noise and provided with a rolling device, and an application method of the worktable device. The worktable device comprises a transmission supporting device which is fixedly connected with a rack, a locking driving motor (4) which is fixedly connected with the rack, a driving screw rod (41) which is in power linkage with the locking driving motor (4), and a locking
assembly (100) which is driven through threads in the driving screw rod (41), wherein a
noise insulation box (13) is arranged in the periphery of the locking driving motor (4) and used for decreasing the
noise generated by operating the locking driving motor (4); the noise insulation box (13) is manufactured from
metal materials, so that the
cooling effect can be achieved; the locking
assembly (100) can be driven by the locking driving motor (4) to position and lock the side part, close to the locking
assembly (100), of the board (300).
