Embodiment approach

[0032] As a preferred embodiment 1, the translation drive motor (15) is a biaxial extension motor, and its motor shaft (16) passes through the connecting plate (17), and the connecting plate (17) is fixed on the bottom of the translation carriage (20). The LMF round flange linear bearing of SKF brand can be installed in the connecting plate (17), so that the connecting plate (17) can freely rotate around the motor shaft (16).

[0033] The relative movement of the gear (18) and the rack (19) is driven by the motor shaft (16), thereby driving the moving cover (3) to move. The rack (19) is fixed on the frame (45), and the gear (18) is driven by the motor shaft (16).

[0034] As a preferred embodiment two, the left fixed sealing plate (5), the middle fixed sealing plate (6), and the right fixed sealing plate (7) are fixed on the frame (45), and the mobile cover (3) can be connected with the left Fixed sealing plate (5), middle fixed sealing plate (6) forms the area of ​​relative ...

specific Embodiment approach

[0044] For the welding method, in addition to the automatic welding of the weld seam, the surface can also be surfacing. If the welding consumables of the welding seam are different from the surfacing welding consumables, it is necessary to replace the welding consumables before continuing to weld. The specific implementation method is:

[0045] After completing the described butt weld seam welding, then carry out surface overlay welding along the circumference or palm surface formed by each of the palm sheets; the specific steps are:

[0046] K) The mobile cover (3) moves to the left side, forms a relatively closed area with the left fixed sealing plate (5) and the middle fixed sealing plate (6); the rotary motor (26) drives the left automatic chuck (31) to rotate;

[0047] L) the laser radar (11) is driven by the direct driver (10), and scans the drill bit (33) to be welded layer by layer from top to bottom or bottom to top;

[0048] M) the three-dimensional laser point cl...

Abstract

The invention relates to a double-station automatic tooth palm welding and process grinding equipment and a welding method. For the current tricone or composite drill bit in the process of palm butt welding and surface surfacing, it is manually performed, the efficiency is low, and the technical demand for relying on human skills is very large, mainly through the welding robot for the two stations. The drill bits to be welded are welded in turn, and the drill bits to be welded at the two stations are polished in turn by the grinding mechanism. The beneficial effect of the present invention is that it has a certain degree of automation, one-time clamping, and automatically completes the automatic butt welding of two drill bits, which has the advantages of high production efficiency, stable welding state, and better protection for workers' health. .

Description

technical field [0001] The invention relates to a special welding equipment for a tricone drill bit or a tricone composite drill bit; specifically, a dual-station automatic tooth palm welding and process grinding equipment, and a welding method using the equipment. Background technique [0002] In oil drilling, the most widely used drill bit that can adapt to various formations so far is the roller cone bit. The most widely used roller cone bit is the tricone bit, which is widely used in oil, natural gas drilling and other geological drilling. The working principle of the drill bit is: the tri-cone bit is connected to the drill pipe through the connecting thread, the drill rig drives the drill pipe to rotate and applies axial pressure, the rotation of the tri-cone bit drives the rotation of the three cones, and the cemented carbide on the three cones The teeth impact the rock and break the formation. [0003] The three-cone drill bit used for mining drilling consists of th...
