Bouncing measurement device of end surface of end cover of planetary double-tubular motor

Abstract

The invention discloses a bouncing measurement device of the end surface of an end cover of a planetary double-tubular motor. The bouncing measurement device is composed of a base, a first lead screw,a left clamper, a right clamper, an internal fluted disc, a drive motor, a central gear, a planetary gear and a bouncing meter. The left clamper and the right clamper are welded to upper sides of a first sliding block and a second sliding block respectively. The planetary gear is engaged between the central gear and engaging teeth at the inner edge of the internal fluted disc; a connection shaftis installed at the core of the planetary gear in an interference fit manner; and the bouncing meter is fixedly connected to the lower end of the connection shaft. The measurement device is able to clamp end covers with different diameters, so that the universality of the device is improved substantially; because rubber protection gaskets are arranged at the inner sides of arc clampers of the leftclamper and the right clamper, the electrophoresis layer at the surface of the end cover can be protected from being damaged when the end cover is clamped; with planetary rotation, the bouncing metermakes circling motion and works stably during the circling motion process, so that bouncy detection becomes accurate.

Description

technical field [0001] The invention relates to a detection device, in particular to a device for measuring runout of the end cover of a planetary double-through-flow motor. Background technique [0002] Runout refers to the difference between the maximum and minimum readings measured by a fixed-position indicator in a given direction when the measured element rotates around the reference axis for one revolution. The circular runout tolerance is the maximum allowable variation of the indicator value when the measured element rotates one circle around the datum axis at a fixed reference point (parts and measuring instruments have no axial displacement). [0003] When performing a runout test on the end face of the end cover, it often occurs that the electrophoretic layer on the surface of the end cover is damaged due to clamping of the clamp arm, resulting in oxidation and rust. At the same time, during the measurement, the runout test error is large due to the unstable opera...
