Torsional force value calibration workbench

Abstract

The invention relates to the technical field of mechanics metering, and especially aimed at calibration of a torsional force value device, a torsional force value calibration workbench is specificallyprovided. The workbench comprises a calibration platform, at least four calibration stations, at least two image acquisition devices, and a computer. The at least four calibration stations are arranged on the upper surface of the calibration platform. Each calibration station comprises a fixing device and a force application device. Each image acquisition device can obtain calibration images of at least two calibration stations of a corresponding column and transmit the images to the computer. The computer compares the obtained calibration images with a standard image to obtain state errors.Through the state errors, a to-be-calibrated torsional force value device is calibrated. The calibration workbench does not need a precise sensor, and realizes precise calibration on various torsionalforce value devices, and ensures calibration precision. The calibration workbench can adapt to different working environments and repeated installation debugging before calibration is not needed, soas to improve calibration efficiency.

Description

technical field [0001] The invention relates to the technical field of mechanical measurement, in particular to the calibration of a torque value device, and specifically provides a torque value calibration workbench. Background technique [0002] Torque is a special moment that causes an object to rotate. In various product fields such as shafts, bearings, and bottle caps that require torque measurement, torque value devices such as torque testers are usually used for detection, testing and calibration, thus requiring torque The precision of the force value device itself is higher, and it needs to be calibrated before work. Existing torque value calibration devices either have a simple structure and low calibration accuracy. For example, patent CN201520977687.4 discloses a torque value calibration workbench, which includes a support frame and a worktable on the support frame. Fix multiple mounting holes and multiple fixing fixtures for the push-pull force gauge and torque ...
