Rapid eccentric distance measuring device for eccentric wheel of miniature diaphragm pump

The utility model discloses an eccentric distance rapid measuring device used for a miniature diaphragm pump eccentric wheel, comprising a pedestal which is provided with a motor; the base is a magnetic attraction base, and a switch is arranged on the base and used for controlling the magnetic attraction base to attract the motor. A mounting rack is fixedly arranged on the side surface of the base, a dial indicator is arranged on the mounting rack, and a contact block is arranged at the end of a measuring rod on the dial indicator; compared with the prior art, in the prior art, an aperture is used as a reference surface, a three-jaw chuck is used for clamping a plug gauge, the plane of an eccentric wheel is tightly close to the plane of a clamping jaw, then a contact of a dial indicator is pointed on the outer circle of the eccentric wheel, the eccentric wheel is slowly rotated, and the reading on the dial indicator is a double eccentric distance value, so that the working efficiency is very low; according to
