When the first cylinder sensor sends an in-place signal, the second cylinder 3341 drives the abutting piece 3342 up so as to sandwich the two support plates 3221 between the two abutting pieces 3342, and then the second cylinder sensor sends an in-place signal.
The turntable sensor 333 is provided at a position near the positioning post 3311 on top of the turntable 321. When the position of the turntable 321 is unchanged, the turntable sensor sends a bit signal.
When the rotating table 321 is driven by the rotating shaft to rotate along the first preset direction to a position parallel to the plane of the rear bracket 16, one of the rotating positioning mechanisms 33 positions the rotating table 321 so as to stop rotating the rotating table 321 and keep the position motionless, until the rotating positioning mechanism 33 is released from positioning, when the rotating table 321 is driven by the rotating shaft to rotate along the second preset direction to a position parallel to the plane of the rear bracket 16, the other rotating positioning mechanism 33 positions the rotating table 321 so as to stop rotating the rotating table 321 and keep the position motionless. The first predetermined direction is opposite to the second predetermined direction, e.g., if the first predetermined direction is clockwise, the second predetermined direction is counterclockwise; if the first predetermined direction is counterclockwise, the second predetermined direction is clockwise.
When the rotation stage 321 stops rotating and the holding position is not moved, the clamping fixture device 20 may be mounted and fixed on the support plate 3221 positioned above the first support frame 171, and then the battery cover plate 1 to be milled is clamped on the clamping fixture device 20. By rotation of the rotary table 321, the clamping fixture device 20 and the battery cover plate 1 are rotated to the other side toward the rear bracket 16, and at the same time, the support plate 3221 on the other side is rotated to the side away from the rear bracket 16; the milling device 40 can then mill the battery cover plate 1 facing the rear bracket 16, while another set of clamping devices 20 can be mounted and fastened to the support plate 3221 on the side facing away from the rear bracket 16 and clamping another battery cover plate 1 to be milled.
