Electric cylinder loading overlapping type force standard machine

Abstract

The invention discloses an electric cylinder loading overlapping type force standard machine. The electric cylinder loading overlapping type force standard machine comprises a support, a reversing frame, a connection guide piece, a standard sensor and power equipment, wherein the support comprises a base and an upper supporting seat; the reversing frame comprises a reversing frame upper beam, a reversing frame lower beam and a reversing frame connection rod; the reversing frame lower beam is arranged between the base and the upper supporting seat; the top of the reversing frame lower beam is provided with a sensor mounting seat; the connection guide piece comprises a mounting plate, a guide rod and a ball screw; the tops of the guide rod and the ball screw are arranged at the bottom of the mounting plate; the standard sensor is arranged on the mounting plate; the power equipment is arranged on the upper supporting seat. The power equipment drives a screw rod of the ball screw to rotate so that the screw moves upwards in the vertical direction, and the mounting plate is driven to move upwards to drive the reversing frame to wholly upwards move so that only electric energy needs to be consumed when pressing direction measurement is carried out on a sensor to be detected which is pressed on the upper supporting seat; the energy consumption is low and oil leakage is not caused; the electric cylinder loading overlapping type force standard machine has a simple and stable structure and high measurement precision and is easy to operate, and can be used for applying different force values according to requirements and measuring a small force value.

Description

technical field [0001] The invention belongs to the field of mechanical performance detection, and in particular relates to an electric cylinder loading and superposition type force standard machine. Background technique [0002] In recent years, load cells and load cells have been widely used in design departments, machinery, electronics, metallurgy, national defense and construction industries. With the rapid development of the production and use of various sensors, it is urgent for the metrology department to conduct comprehensive and accurate inspections and provide consistent and reliable technical indicators. To this end, our country has built various types of force standard machines. [0003] The force standard machine uses a standard force sensor with higher accuracy than the verified force gauge as a standard, which is connected in series with the calibrated / verified force sensor and loaded hydraulically; due to its low cost and high work efficiency , In recent ye...
