Description

Technical Field

[0001] The invention relates to the field of petroleum exploration, and in particular to a special-shaped PDC laser engraving processing equipment and an operating method. Background Art

[0002] PDC is the abbreviation of petroleum exploration diamond composite.

[0003] The existing PDC cutting teeth are of planar structure. With the improvement of efficiency in the oil exploration and geological exploration industries, the original planar PDC drill bit cutting tooth technology has reached a bottleneck relative to the high-speed and high-pressure drilling technology requirements. It is necessary to improve the process on the basis of the original planar teeth. Therefore, special-shaped PDCs appear, that is, PDC cutting teeth have various pattern structures, such as triangles and convex structures.

[0004] The existing special-shaped tooth processing technology is mostly grinding and pre-pressing. Since the hardness of diamond is HV7500-9000, which is second only to natural diamond, the processing efficiency of grinding is difficult to meet the needs of mass production, and it cannot meet the needs of some special special-shaped chamfering processes. For the pre-pressing process, the post-processing also faces the same dilemma as grinding, but the grinding amount is reduced. In addition, the existing processing technology has no good processing method for some concave open surfaces. Summary of the invention

[0011] Further, the workpiece positioning fixture moves on a positioning X-axis, and the positioning X-axis moves on a positioning Y-axis.

[0012] Furthermore, the working platform is made of marble. Based on the same invention concept, an operating method of a special-shaped PDC laser engraving processing equipment is also applied, comprising the following steps:

[0013] S1, draw a three-dimensional model and import the three-dimensional model into the operation control system;

[0014] S2, placing the PDC on the positioning column;

[0015] S3, calculate the PDC center through the autofocus system and the visual automatic positioning system;

[0016] S4, by moving the PDC positioning fixture on the positioning X-axis and the positioning Y-axis, the PDC center is moved to the bottom of the laser generator for laser engraving, and the engraving of the PDC special-shaped teeth is completed;

[0017] S5, after the processing of the previous PDC special-shaped tooth is completed, the next PDC is automatically moved to the bottom of the laser generator through the positioning X-axis and the positioning Y-axis for laser engraving.

[0018] Beneficial effects of the present invention:
