AI Technical Summary

Technical Problem

In existing grinding processes, grinding the inner and outer walls of crankshaft damping pulleys requires secondary clamping and positioning, which is cumbersome and inefficient, and cannot meet the adjustment needs of crankshaft damping pulleys of different specifications.

Method used

A crankshaft vibration damping pulley outer diameter grinding device was designed, including a grinding component, a clamping component, a pushing component, and a dustproof component. The device achieves automated adjustment through a two-way telescopic frame and a power unit, reducing manual intervention and enabling one-time grinding of the inner and outer walls.

Benefits of technology

It improves the ease and efficiency of grinding crankshaft damping pulleys, avoids secondary grinding, enhances automation and grinding effect, and simplifies the operation process.

Abstract

The application relates to the technical field of pulley outer diameter grinding, and discloses a pulley outer diameter grinding device for a crankshaft damping pulley. The pulley outer diameter grinding device comprises a workbench, the top of the workbench is fixedly connected with an operating frame, a jack is arranged on the top of the workbench, and a plug hole is arranged on the top of the workbench; the inner wall of the plug hole is inserted with a protective cover; the grinding part comprises a moving plate, the surface of the moving plate is fixedly connected with a sliding hole plate, and the inner wall of the sliding hole plate is slidingly connected with a protective frame. The bidirectional telescopic frame pushes the rectangular grinding block into contact with the surface of the crankshaft damping pulley; when the driving device starts to work, the driving device drives the crankshaft damping pulley to rotate through the clamping part; the rectangular grinding block is ground on the outer diameter of the crankshaft damping pulley through the rotation of the crankshaft damping pulley; the position of the rectangular grinding block is adjusted through the bidirectional telescopic frame; the convenience of the crankshaft damping pulley in outer diameter grinding is improved; and the distance between the rectangular grinding block and the crankshaft damping pulley does not need to be adjusted by workers.
