Tensioning wheel on-line pressing rivet and damping moment detection device

Abstract

The invention specifically relates to a tensioning wheel on-line pressing rivet and damping moment detection device, which comprises a servo electric cylinder, a pressure sensor, a rotary riveting servo motor, a first servo motor, a torque sensor and a micro computer. The servo electric cylinder pushes the pressure sensor to descend; the pressure sensor pushes a pressure head to descend and abut against a tensioning wheel; the rotary riveting servo motor drives a riveting rod to carry out pressing rivet on the tensioning wheel; during pressing rivet, the first servo motor drives a rotating rodto rotate; the rotating rod drives a rotation plate to rotate; the rotation plate pushes a tool support of the torque sensor to apply torque to the tensioning wheel, and the torque is measured by thetorque sensor; and the torque sensor inputs the measured data into the micro computer for analysis and control. The device can finish assembly of the tensioning wheel online, measure the change between the torsion and angle of the tensioning wheel online, calculate damping coefficient and can judge whether the tensioning wheel is qualified on site.

Description

technical field [0001] The invention relates to assembly and testing equipment for auto parts, in particular to an online pressure riveting and damping torque testing equipment for a tension wheel. Background technique [0002] In the prior art, a tensioner pulley for a vehicle is a device arranged to apply a predetermined tension force to a belt after the belt is installed in a belt and pulley assembly, the tensioner pulley typically consists of a rotating body to Reduce belt friction. [0003] Among the current tensioner production equipment, there are only experimental equipment for the durability of the tensioner and bearing fatigue, but no testing equipment for the damping coefficient of the tensioner, so it is impossible to directly judge whether the damping of the tensioner is qualified, only manual inspection, The error is large, and the substandard products are often shipped out of the factory, causing the cars using the substandard products to be damaged early. In...

[0003] Among the current tensioner production equipment, there are only experimental equipment for the durability of the tensioner and bearing fatigue, but no testing equipment for the damping coefficient of the tensioner, so it is impossible to directly judge whether the damping of the tensioner is qualified, only manual inspection, The error is large, and the substandard products are often shipped out of the factory, causing the cars using the substandard products to be damaged early. In order to solve this problem, the current solution is to use a separate device to test the damping coefficient of the tensioning wheel and test the product. Insufficient, and the fixation method of the tooling is more complicated, and the disassembly of the product is more time-consuming, labor-intensive and time-consuming
