A jig and reaming device for machining a workpiece having an internal cavity

Abstract

This utility model discloses a fixture and a hole-reaming device for machining workpieces with internal cavities. The fixture includes a base, a driver, and at least one clamping module for inserting the workpiece from top to bottom. The clamping module includes a positioning seat, a pull rod, and a slider. The positioning seat is fixedly connected to the base, the pull rod is slidably connected to the positioning seat in the longitudinal direction, and the slider is confined within the positioning seat. The driver is fixed to the base and connected to the pull rod. The driver drives the pull rod to move up and down. The rising and falling of the pull rod drives the slider to move laterally reciprocally relative to the base by laterally pressing the slider. When the slider extends laterally, both the slider and the positioning seat abut against the side wall of the inner cavity of the workpiece to expand and clamp the workpiece. This application mainly solves the technical problem of how to clamp workpieces with internal cavities when machining is required without causing damage or deformation to their surface.
