Strain gauge pasting device and method for harmonic reducer fault diagnosis

Abstract

The invention provides a strain gauge pasting device and method for harmonic reducer fault diagnosis. The strain gauge pasting device comprises a base flange assembly, a force control assembly, a telescopic rod with a seat cushion and a compression screw. The base flange assembly comprises a mounting flange cover, a boss with a threaded hole and a supporting seat with a hole, the boss with the threaded hole and the supporting seat with the hole are mounted on the flange cover through screws, and the mounting flange cover is buckled on a harmonic speed reducer in a matched mode through an inner hole; the force control assembly comprises a pressing cover, a pressure-bearing seat and a spring assembly, and the distance between the pressing cover and the pressure-bearing seat can be controlled through a telescopic spring; the telescopic rod with the seat cushion penetrates through the pressure-bearing seat and the pressing cover and is embedded into the mounting flange cover, and the bottom of the telescopic rod with the seat cushion is used for fixing the resistance strain gauge; and the compression screw penetrates through the pressing cover and is fixed to the boss with the threaded hole. When the strain gauge pasting device is used, the strain gauge is fixed to the seat cushion at the bottom of the telescopic rod, after glue is dripped, the elastic force of the spring is adjusted by the compression screw, so that the telescopic rod is controlled to move, and the compression and pasting of the strain gauge are completed.

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...
