A positioning fixture for machining engine impellers

Abstract

This utility model discloses a positioning fixture for machining engine impellers, relating to the field of engine impeller machining technology. It includes a clamping base, with four first electric push columns fixedly installed around its interior. A sliding block is fixedly installed on one side of each first electric push column, a clamping block is fixedly installed on the top of each sliding block, a silicone block is fixedly installed on one side of each clamping block, and a baffle plate is fixedly installed on the top of one side of each sliding block. This positioning fixture for machining engine impellers, through the movement of the second electric push columns, drives the sliding plate to move outwards within the slide rail, causing the silicone plate on one side of the support block to adhere to the interior of the impeller, thus clamping the impeller. The contraction of the electric push rod inside the sliding plate causes the support block to move downwards, increasing friction by the silicone plate adhering to the inner wall of the impeller, further moving the impeller downwards and ensuring it adheres to the clamping base, thus preventing clamping misalignment.
