TECHNICAL FIELD
[0001] The utility model relates to drill bit processing technical field especially relates to a clamping device for drill bit surface treatment. BACKGROUND
[0002] The petroleum drill bit is an important tool for petroleum drilling, and is used for drilling petroleum when petroleum is exploited. The working performance of the petroleum drill bit directly affects drilling quality, drilling efficiency and drilling cost. After the petroleum drill bit is processed by a machining center, the surface of the drill bit needs to be treated, including surface polishing and paint spraying.
[0003] Under the existing technical system, many clamping devices for drill bit surface treatment have components responsible for extruding and fixing the drill bit, which are designed as two arc-shaped structures with fixed radii. From the design principle, the arc-shaped extruding components aim to be in close contact with the outer wall of the drill bit through a specific radius, and rely on mechanical pressure or other external forces to achieve stable clamping of the drill bit. However, this design has significant limitations. Since the radius is fixed and cannot be changed, it can only adapt to a drill bit of a certain single diameter in actual application scenarios. Once facing a drill bit of a different diameter, the extruding component with a fixed radius cannot be in good contact with the outer wall of the drill bit. When the clamping diameter is smaller than the drill bit of the adapted specification, there will be a large gap between the arc-shaped component and the drill bit, which cannot provide enough extruding force, causing the drill bit to easily shake and displace during clamping, seriously affecting the precision and quality of subsequent surface treatment. When trying to clamp a drill bit with a diameter larger than the adapted specification, the arc-shaped component cannot completely wrap the drill bit, making the clamping operation impossible.
