Abstract

An automatic resistance adjusting machine for a resistance type strain gage includes a frame and a working platform arranged on the frame and used for fixing the resistance type strain gage; the invention also includes a grinding head arranged above the working platform; the grinding head is arranged on a motor output shaft; the motor is fixed on a feed mechanism of the grinding head; the feed mechanism of the grinding head is arranged on a transverse moving mechanism; the transverse moving mechanism is arranged on a longitudinal moving mechanism; the invention also includes a probe for detecting the resistance, a resistance detection circuit and a main control circuit; the invention completely abandons the existing working mode of manually correcting the resistance value of the resistance type strain gage and designs a novel automatic resistance type strain gage detecting and correcting device, thus greatly reducing the working intensity of workers, greatly improving the manufacture efficiency and leading the precision of a product to be greatly improved with good working stability.

Description

technical field [0001] The invention relates to a resistance measuring and correcting instrument, in particular to an automatic resistance adjustment machine for resistance strain gauges. [0002] Background technique [0003] Resistance strain gauge is the most widely used resistive sensor made by the principle of resistance effect. It is mainly used in the inspection of mechanical quantities, such as the detection of physical quantities such as gravity and pressure, and has high requirements for resistance accuracy. Conventional resistance strain gauges are all made by chemical corrosion, and the resistance value of the produced resistance strain gauges is low, which cannot meet the requirements for use. Therefore, the resistance strain gauge of the semi-finished product must be automatically adjusted before use. [0004] At present, the automatic resistance adjustment of the resistance strain gauge is mainly carried out by manual operation. The operator holds a miniatur...
