Linear reciprocating type magnetic shoe shape measuring device

A linear reciprocating type magnetic shoe shape measuring device disclosed by the present invention comprises a bracket, a lifting plate, a measuring mechanism and a driving mechanism, the bracket is provided with two groups of vertical plates, the rear side of the bracket is provided with a discharging table, the lifting plate is provided with a plurality of groups of carrying grooves and a group of transverse grooves, and the measuring mechanism comprises an upper measuring part and a lower measuring part which are vertically distributed on each carrying groove. The driving mechanism is used for driving the lifting plate to keep horizontal placement of the magnetic shoe and measuring the magnetic shoe, and driving the lifting plate to overturn upwards after measurement, so that the measured magnetic shoe slides to the discharging table; the displacement assembly drives the lower measuring part to measure the inner arc of the magnetic shoe and drives the upper measuring part to measure the outer arc of the m
