Machining precision adjusting device for five-axis linkage planer type milling machine

The utility model discloses a machining precision adjusting device of a five-axis linkage planer type milling machine, and belongs to the field of five-axis linkage planer type milling machines. The machining precision adjusting device of the five-axis linkage planer type milling machine comprises a fixed bed and a detection table, the top end of the fixed bed is connected with the detection table in a sliding mode, and clamping plates are connected to the positions, on the two sides of a middle vertical plate, inside side grooves in a sliding mode. In order to solve the problems that in the prior art, an object is placed on the inner side of a side fixing plate, then an outer sliding plate and a sliding groove are pushed to slide at the top end of a convex strip, so that the object is limited and clamped by a side connecting plate and a clamping plate, and the clamping plate and a middle vertical plate are connected through an extension spring, so that the object can be accurately placed on the detection tab
