Problems solved by technology

[0004] In order to solve the problem that the auxiliary tools in the prior art usually fix the drill pipe and then process the texture of the drill pipe body, but it is impossible to remove the dirt attached to the drill pipe body before the drill pipe is processed, which makes it inconvenient for the processing personnel. Accurately locate the required thread processing station on the shaft of the oil drill pipe, and then affect the technical problem of the thread processing accuracy of the oil drill pipe. The invention provides an auxiliary device for thread processing of the oil drill pipe

Embodiment 1

[0030] Please combine Figure 1 to Figure 3 , The auxiliary device for thread processing of oil drill pipes includes an open groove 1, a clamping mechanism arranged on the open groove 1 for fixing the drill pipe (not shown), and a spray mechanism for cleaning the drill pipe. The open groove 1 in this embodiment has a rectangular parallelepiped structure as a whole. The drill pipe in this embodiment is an oil drill pipe.

[0031] The clamping mechanism includes two clamping assemblies clamped at both ends of the drill rod and a driving mechanism for driving the drill rod to reciprocate horizontally. The spraying mechanism includes a spraying head 3 suspended above the drill pipe and a driving mechanism 2 for guiding the horizontal reciprocating movement of the spraying head 3 . The cleaning water source of the spray head 3 in this embodiment can be connected with external liquid supply equipment. Through the driving mechanism 1 and the driving mechanism 2, the spray head 3 a...

Embodiment 2

[0043] Please combine Figure 4 , this embodiment 2 is an improved solution of embodiment 1, specifically, the guide plate one 31 is connected to the corresponding groove wall of the open groove 1 at the discharge port 32 by rotation. The block body of slide block two 20 is fixed with the synchronous bar one 38 that is perpendicular to chute two 19, and the other end of synchronous bar one 38 is provided with the synchronous bar two 39 that is perpendicular to it, and synchronous bar two 39 penetrates the opening groove 1 and is connected with an inclined platform 37. The top of the ramp 37 has a slope (not shown). The bottom of one end of the guide plate one 31 away from the discharge port 32 is provided with a connecting rod three (not marked) parallel to the synchronous rod one 38, and the bottom of the connecting rod three is provided with a roller 36 matched with the inclined surface.

[0044] In the second embodiment, the second slider 20 can drive the ramp 37 to recip...

Abstract

The invention relates to the technical field of petroleum drill rod machining, and discloses a petroleum drill rod thread machining auxiliary device. The device comprises an open groove, a clamping mechanism arranged on the open groove and used for fixing a drill rod and a spraying mechanism used for cleaning the drill rod. The clamping mechanism comprises two clamping assemblies clamped at the two ends of the drill rod and a first driving mechanism used for driving the drill rod to horizontally move in a reciprocating mode. The spraying mechanism comprises a spraying head arranged above the drill rod in a suspended mode and a second driving mechanism used for guiding the spraying head to horizontally move in a reciprocating mode. By means of the clamping mechanism and the spraying mechanism which are arranged on the open groove, the drill rod can be rapidly clamped and fixed before thread machining of the drill rod, then dirt attached to a rod body of the drill rod is removed, a needed thread machining station can be accurately positioned on the rod body of the drill rod by machining personnel, and the thread machining precision of the petroleum drill rod is guaranteed.

Description

technical field [0001] The invention relates to the technical field of oil drill pipe processing, in particular to an auxiliary device for thread processing of oil drill pipes. Background technique [0002] The purpose of the drill pipe is to transport the drilling mud to the drill bit and together with the drill bit to raise, lower or rotate the bottom hole device. Drill pipe must be able to withstand enormous internal and external pressure, twisting, bending and vibration. [0003] The raw material for making drill pipe is cylindrical. When making oil drill pipes, it is necessary to make drill pipe lines on the body of the drill pipe to meet the requirements of the drill pipe. In the existing auxiliary tools, the drill pipe is generally fixed and then the texture of the drill pipe body is processed, but it is impossible to remove the dirt attached to the drill pipe body before the drill pipe is processed, which makes it inconvenient for the processing personnel to work o...
