Gear outer diameter end jump and length detection device

The utility model discloses a gear outer diameter end jump and length detection device, relates to the technical field of gear detection, and solves the problems that the accuracy of measured data is difficult to effectively improve, the operation labor intensity is relatively high, the working efficiency is relatively low, data reading errors exist and the like. The clamping driving mechanism comprises a supporting plate and a tip, a first servo motor is fixedly installed at one end of the tip, auxiliary frames are slidably connected to the outer sides of the sliding rails correspondingly, measuring plates are fixedly installed on one face of the supporting plate correspondingly, moving blocks are slidably connected to the surfaces of the measuring plates correspondingly, and first inductance micrometer gauges are arranged in the moving blocks. According to the invention, a to-be-detected workpiece can be clamped by moving the supporting plate so that the tips which are rotatably connected to the outer side
