Substrate mounting machine base, has base body with thread having thread diameter for screwing base with chassis of mounting machine, and another thread formed at base body with thread diameter larger than former thread diameter

摘要

The base has a base body (8) with a thread (11) having a thread diameter (D1) for screwing the base with a chassis (3) of a mounting machine. Another thread (12) is formed at the base body with a thread diameter (D2), which is larger than the diameter (D1). A counter nut (13) is screwable along the thread (12) such that the nut is aligned with the chassis in a condition, in which the base is screwed with the chassis by the thread.
