Scrap iron blowing clamp

Abstract

The invention relates to a scrap iron blowing clamp for blowing scrap iron of honeycomb parts, wherein excircle multi-hole of the honeycomb parts is communicated with end surface grooves. According to the technical proposal, the scrap iron blowing clamp comprises a positioning core axel which is fixedly connected along the axial direction in a columnar body, and is characterized in that at least one end part of the positioning core axel extends out of the end face of the columnar body; an extending end is formed on the positioning core axel; the end surface of the columnar body, which is close to the extending end, is provided with an air outlet dent around the positioning core axel; the lateral surface of the columnar body is provided with an air inlet hole communicated with the air outlet dent; and a sealing ring is arranged on the circumferential wall and / or the bottom surface of the air outlet dent. The scrap iron blowing clamp has the advantages of high scrap iron blowing efficiency, prevention of colliding workpieces and the like.

Description

technical field [0001] The invention relates to a fixture used for blowing iron filings of components such as outer circular porous and end face grooves communicating (honeycomb). Background technique [0002] The design requirements of today's small parts are complicated in shape and many small holes, so the requirements for the surface quality and cleanliness of the workpiece are getting higher and higher. Porous parts need special blowing tools to meet the drawings and customer requirements. The original chip blowing device has the following two disadvantages: 1. Low efficiency (need to blow the small holes one by one with an air gun); 2. Poor quality (Iron filings will be strung into the small holes that have been blown through). Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art, and provide a chip blowing jig that has high chip blowing efficiency and prevents bumping into workpieces. [0004] Acco...
