Abstract

The invention provides a strain gauge pasting device and method for fault diagnosis of a harmonic reducer. The device includes a base flange assembly, a force control assembly, an expansion rod with a seat cushion and a compression screw; the base flange assembly includes Install the flange cover, the boss with threaded holes and the support seat with holes. The boss with threaded holes and the support seat with holes are installed on the flange cover through screws, and the flange cover is buckled on the harmonic reducer through the inner hole. ;The force control assembly includes a gland, a pressure seat and a spring assembly, and the distance between the gland and the pressure seat can be controlled by a telescopic spring; the telescopic rod with a seat cushion passes through the pressure seat and the gland, and is embedded in the mounting flange Cover, with seat cushion The bottom of the telescopic rod is used to fix the resistance strain gauge; the compression screw passes through the gland and is fixed on the boss with threaded holes. When the device is in use, the strain gage is fixed on the seat cushion at the bottom of the telescopic rod, and after dripping glue, the compression screw is used to adjust the spring force, thereby controlling the movement of the telescopic rod to complete the compression and pasting of the strain gage.

Description

technical field [0001] The invention mainly relates to the technical field of harmonic reducer detection, in particular to a strain gauge pasting device and method thereof for fault diagnosis of a harmonic reducer. Background technique [0002] In the field of modern engineering testing, strain gauges are widely used to measure torque, bending moment, stress and other physical quantities, so the transmission characteristics of harmonic reducers can also be analyzed through strain gauges. As a high-precision power transmission device, the harmonic reducer has the characteristics of small size, compact structure and high requirements for the assembly environment. When pasting the strain gauges manually or through the existing pasting device, there is a small reserved space and high accuracy. Difficulty in positioning, contamination of the assembly surface of the reducer, etc. [0003] There are two key points when pasting the strain gauges on the harmonic reducer: one is to l...
