Description

Technical Field

[0001] The utility model relates to the technical field of alloy drill bit equipment, in particular to an alloy drill bit with a bidirectionally adjustable cutter head. Background Technique

[0002] The cemented carbide drill bit breaks rocks by means of the drilling pressure and the impact load generated by its own rotation. During rock drilling, the drill bit is subjected to high-frequency impact loads, and is also affected by various combined stresses such as torsion, bending, tension, and compression. In the environment of high-speed rotation and collision, it is subjected to the wear and corrosion of working media such as rocks, rock dust, and mine water. Most of the roller cone bits used at home and abroad are three-cone bits. The characteristics of this kind of drill bit are: the distribution range of the axial pressure and the impact load is large and uniform, and the effective space can be fully utilized, and the drilling is stable. The size and shape of the cemented carbide teeth used in roller cone bits must be suitable for the characteristics of the rock, and it is required to have good wear resistance, high strength, and be not easy to break and fracture. The cemented carbide teeth used in roller cone bits mainly include: spherical teeth, cone-spherical teeth, wedge-shaped teeth, edge-wedge teeth, and flat-top teeth for the wheel back and claw tips, etc.

A positioning pit is opened on the head end face of the boring tool bar, and two boring bars with the same shape and opposite directions are installed in the positioning pit. A kidney-shaped counterbore is opened in the center of the boring bar, and two positioning screws are installed in the kidney-shaped counterbore. By opening a positioning pit on the head end face of the boring tool bar and installing two boring bars with the same shape and opposite directions in the positioning pit, the boring bar can make an axial movement in the positioning pit of the boring tool bar to realize the bidirectional adjustment of the cutter head; by selecting a cemented carbide non-regrind through-hole cutter head and screwing and positioning it with the boring bar, the cutter head can be quickly replaced, which has the advantages of simple structure, long service life, bidirectional adjustment of the cutter head, and convenient replacement of the cutter head.

[0004] However, there are some problems in the use of the existing alloy drill bit with a bidirectionally adjustable cutter head: 1.

When the overall adjustment is carried out, disassembly is required. On the market, the angle needs to be adjusted after disassembly and cannot be adjusted during installation, which reduces the overall use convenience. Content of the Utility Model
