Technical Field

[0001] The utility model belongs to the technical field of milling machine processing, and particularly relates to a milling machine synchronous displacement platform used for milling a keyway of a fan main shaft. Background Art

[0002] The X5024A vertical lifting table milling machine has a worktable length of usually 2000 mm and a worktable feed length of usually 1250 mm. When the worktable is in the middle, due to the existence of the milling machine limit, the maximum stroke of the worktable to the left is 625 mm, and the maximum stroke to the right is 625 mm. The worktable limit block is installed on the milling machine worktable and moves synchronously with the milling machine worktable. The milling machine limit block is installed on the milling machine and the milling machine limit block cannot move. When the milling machine worktable moves to the left or backward, the worktable limit block and the milling machine limit block contact each other, and the milling machine reaches the limit position and cannot move further. At this time, when the keyway is processed for the spindle with a longer length, it is easy to cause the spindle center of gravity to be unstable, and even the keyway at the end of the spindle cannot be processed.
