Description

Technical Field

[0001] The present application relates to the technical field of shield machine tool brazing positioning tooling, and particularly relates to an auxiliary device for installing shield tools. Background Technique

[0002] Shield machines are increasingly widely used in major projects such as urban subways, railway and highway transportation, energy transmission, and underground channels, and have the advantages of fast excavation speed, high construction quality, low labor intensity, economy, and environmental protection. The cutter of the shield machine is one of the important components of the shield machine body, and its main function is to cut soil layers and rocks under complex geological conditions to provide power support for the advancement of the shield machine. The role of the cutter is to cut the rock and soil into smaller particles to facilitate the advancement of the shield machine. Common cutter types include single-edge hob, double-edge hob, face scraper, edge scraper, tooth cutter, pilot cutter, and center cutter, etc. These tools each have different rock-breaking methods to adapt to different geological conditions.

[0003] The scraper of the shield machine usually consists of a tool body and a cemented carbide tool head. The tool body and the cemented carbide tool head are fixedly connected by brazing. When brazing the tool body and the cemented carbide tool head, a positioning tooling is required for positioning. For example, the utility model with the publication number CN212793463U discloses a cutter brazing tooling. When this cutter brazing tooling is used, the tool body is placed into the groove of the positioning block, and then the positioning block is rotated. During the rotation of the positioning block, the included angle between the bottom end surface of the cemented carbide groove and the horizontal plane continuously changes. When the bottom end surface of the cemented carbide groove is in the horizontal position, the positioning block is fixed. Then, brazing filler metal is placed into the cemented carbide groove, brazing flux is applied, and the cemented carbide is placed into the cemented carbide groove. Then, the fixture and the cutter inside the fixture are placed into the induction coil for heating and brazing.

[0004] However, when the above cutter brazing tooling is used, both the tool body and the cemented carbide tool head are positioned by their own gravity, and no limiting parts are used to limit and fix the tool body and the cemented carbide tool head. It is easy to be accidentally touched and move, and when brazing is carried out, the brazing filler metal will flow after melting, so that the position of the cemented carbide tool head will shift by a certain amount, affecting the brazing accuracy.
