Drilling bit with fixing chucks

Abstract

The invention discloses a drilling bit with fixing chucks. The drilling bit with the fixing chucks comprises a drill bit, a first fixing ring, a first fixing chuck, a screw hole, a first gear, a second gear, a fastening screw, a second chuck, a threaded column, a linkage ring, a rotating rod and six buckle grooves. The drilling bit with the fixing chucks has the beneficial effects that the rotating rod at the bottom end of the first gear is in butt joint connection with the inside of the first fixing chuck and is in threaded rotating connection with the first fixing ring; the second gear is superposed and connected to the upper portion of the first gear and fixed in a fixing hole in the second chuck, the circumstances that teeth are jammed sometimes and thus the service life is not long are prevented, a gear is arranged on the bottom of the rotating rod, the rotating rod is in gear gripped connection with the second gear, linkage of the drill bit is ensured, and the linkage ring is rotatably connected to the top of the second chuck, the six buckle grooves are symmetric in all directions and are formed in the side wall of the linkage ring in a recessed manner, and the circumstance that fixed connection cannot be implemented when the drilling bit is externally connected with a rotating motor is prevented.

Description

technical field [0001] The invention relates to a drilling bit, in particular to a drilling bit with a fixed chuck, and belongs to the technical field of drilling bits. Background technique [0002] The drill bit is the main part of the drilling equipment. Its main function is to break the rock and form the wellbore. The rotary drill bit is a drill bit commonly used in the oil industry. Driven by machinery, the rotary drill bit will rotate, thereby driving the entire drill bit to produce a centripetal The drill bit is one of the main drilling equipment, and the specification and shape of the drill bit should also be different according to the working environment and regional environment. Different, when carrying out oil drilling work, the drill bit should be selected reasonably and scientifically based on the specific needs and specific design schemes. In the specific drilling work, the drill bit should be scientifically selected and the drilling fluid should be reasonably d...

Problems solved by technology

[0003] Therefore, then need a kind of drilling bit that has fixed chuck to satisfy the demand on the market at present, although the multiple drilling bit that has fixed chuck has been produced on the market at present, generally speaking, but There are still many common problems. One, the internal linkage of the existing drilling bit with a fixed chuck only adopts a gear, which causes the teeth to be stuck sometimes, and the service life is not long. The drill bit of the drill bit with a fixed chuck is welded in one piece, so that it cannot be replaced quickly when the drill bit is damaged. Third, the snap groove on the top linkage plate of the existing drill bit with a fixed chuck Insufficient quantity, resulting in the inability to connect and fasten when connecting with an external rotating motor
