Description

Technical Field

[0001] The utility model relates to the technical field of planetary gear frame flatness detection, in particular to a planetary gear frame flatness detection device for a reducer. Background Art

[0002] After the gear is processed, the thickness of each point on the circumference of the gear must be the same to meet the requirements of the standard gear. At present, the detection of gear tooth thickness mainly relies on the operator to use a caliper to take points on the circumference of the gear for segmented testing, and then record the measurement data of each point, and then compare the recorded data to determine whether the gear tooth thickness meets the standard. This measurement method that mainly relies on manual measurement and reading of data is difficult to adapt to the needs of large-scale and assembly line assembly, and has low efficiency;

[0003] The announcement number CN 219083993 U discloses a device for detecting the flatness of a planetary gear frame of a reducer, comprising: a support base, a horizontal level and a vertical level are fixedly connected to the upper side wall of the support base and close to the front side, a rotating seat is fixedly connected to the upper side wall of the four corners of the support base; a support frame is fixedly connected to the upper side wall of the support base;

[0004] When in use, the device requires workers to manually load and unload materials when inspecting workpieces. The loading and unloading process is cumbersome and prone to accidental touches, which can cause the device to tilt. As a result, workers need to frequently adjust the angle of the inspection box, resulting in low work efficiency. Therefore, we propose a reducer planetary gear rack flatness detection device.
