A rack and pinion meshing motor end cover runout measuring device

Abstract

The invention discloses a gear rack meshing type motor end cover end surface run-out measuring device which comprises a base, a first screw rod, a left clamping hand, a right clamping hand, an inner gear disc, a driving motor, a center gear, a planetary gear and a run-out table, the left clamping hand and the right clamping hand are respectively welded on the upper sides of a first sliding block and a second sliding block, and the planetary gear is connected between the center gear and the meshing teeth at the inner edge of the inner gear disc in a meshed mode, a connecting shaft is arranged at the gear core of the planetary gear in an interference fit mode, and the run-out table is fixedly connected to the lower end of the connecting shaft. According to the measuring device, the end covers with different diameters can be clamped, and the universality of the device is greatly improved; rubber protection pads are arranged on the inner sides of the arc-shaped clamps on the left clampinghand and the right clamping hand, so that the electrophoresis layer on the surface of the end cover is effectively prevented from being damaged when the end cover is clamped; and by means of the planetary type rotation, the run-out table performs circular motion, and can run stably in the circular motion process, so that the run-out detection is more accurate.

Description

technical field [0001] The invention relates to a detection device, in particular to a measurement device for measuring the runout of the end face of the end cover of a rack and pinion 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 ...

[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 operation of the measuring device
