Drill bit tooth pressing device and thermal tooth inserting equipment with drill bit tooth pressing device

Abstract

The invention relates to a drill bit tooth pressing device and thermal tooth inserting equipment with the drill bit tooth pressing device. The drill bit tooth pressing device comprises a rack. A base body positioning base used for fixing a drill bit base body and a telescopic tooth pressing device corresponding to tooth holes in the drill bit base body are arranged on the rack. The telescopic tooth pressing device is provided with pressing heads extending forwards in the axial direction of the corresponding tooth holes and pressing tooth heads into the corresponding tooth holes in the drill bit base body. A base body positioning base has the axis extending in the axial direction of the drill bit base body fixed to the base body positioning base. The telescopic tooth pressing device is rotationally assembled on the rack around the axis of the base body positioning base or the base body positioning base is rotationally assembled on the rack around the axis of the base body positioning base. After the drill bit base body is fixed, the base body positioning base or the telescopic tooth pressing device is rotated so that the tooth holes in the drill bit base body can correspond to the pressing heads of the telescopic tooth pressing device respectively, and then the tooth heads are pressed through power of the telescopic tooth pressing device. According to the drill bit tooth pressing device and the thermal tooth inserting equipment with the drill bit tooth pressing device, alignment is easy, operation is convenient, production efficiency is high, and product quality can be well controlled.

Description

technical field [0001] The invention relates to a gear pressing device for a drill bit and a thermal inserting equipment using the device. Background technique [0002] At present, tools such as down-the-hole drill bits and tophammer drill bits are widely used in fields such as exploration, earthwork engineering, mining drilling, and oil drilling. Down-the-hole drills and top hammer drills are generally composed of a steel drill base and a carbide tooth head or a diamond composite tooth head embedded in the drill base. Due to operational requirements, the tooth head is generally divided into axes extending along the axial direction of the drill bit The straight tooth head and the helical tooth head whose axis forms a certain angle with the axial direction of the drill bit, the straight tooth head and the helical tooth head are all circular and evenly distributed around the axis of the drill bit base. When manufacturing the drill bit in the prior art, the gear hole is first ...
