Abstract
The utility model provides a kind of dental lamina base of oil drilling tools dismounting facility, and its body is truncated rectangular pyramids, and its cross section is isosceles trapezoid; The upper surface of described body has the through slot running through described body front-back, the bottom surface of this through slot has the U-lag running through described body front-back; The center, lower surface of described body has a square groove, and the body lower surface of the described square groove left and right sides respectively has a fixing hole.This design effectively prevents dental lamina from departing from, and the clamping force solving workpiece is uneven or after clamping, workpiece, not in the problem of pivot, protects dental lamina not cause damage simultaneously.
Description
Technical field
The invention relates to oil drilling tools changer clamp art, is specifically related to a kind of dental lamina base of oil drilling tools dismounting facility.
Background technology
As everyone knows, oil drilling tools changer has two clamping clips, and one is fix to clamp, and another rushes clip tightly, and its fastening realizes based on the action of piston rod in oil cylinder.What drilling tool changer clamping cylinder traditional at present adopted is outer guiding oil cylinder, clamp dental lamina used easily to depart from, and after uneven or clamping, workpiece, not at pivot, also can cause damage to dental lamina, even can not work time serious to the clamping force of workpiece simultaneously.
Summary of the invention
What the invention will solve is that oil drilling tools dismounting facility dental lamina is not fastening, the problem easily departed from.
For solving the problems of the technologies described above, the technical scheme that the invention adopts is: a kind of dental lamina base of oil drilling tools dismounting facility, and its body is truncated rectangular pyramids, and its cross section is isosceles trapezoid; The upper surface of described body has the through slot running through described body front-back, the bottom surface of this through slot has the U-lag running through described body front-back; The center, lower surface of described body has a square groove, and the body lower surface of the described square groove left and right sides respectively has a fixing hole.
Further, the bottom surface of described fixing hole is taper.
Further, before and after described square groove both sides body lower surface on respectively have first connecting hole.
Further, the first connecting hole bottom surface has the second connecting hole with its axial line conllinear.
Further, the radius of described second connecting hole is greater than the radius of described first connecting hole.
The advantage that the invention has and good effect are: effectively prevent dental lamina from departing from, and the clamping force solving workpiece is uneven or after clamping, workpiece, not in the problem of pivot, protects dental lamina not cause damage simultaneously.

Detailed description of the invention
A dental lamina base for oil drilling tools dismounting facility, its body 1 is truncated rectangular pyramids, and its cross section is isosceles trapezoid; The upper surface of described body 1 has the through slot 11 running through described body 1 front-back, the bottom surface of this through slot 11 has the U-lag 12 running through described body 1 front-back; The center, lower surface of described body 1 has a square groove 13, and body 1 lower surface of described square groove 13 left and right sides respectively has a fixing hole 14.
The bottom surface of described fixing hole 14 is taper.
Before and after described square groove 13 both sides body 1 lower surface on respectively have first connecting hole 15.
First connecting hole 15 bottom surface has the second connecting hole 16 with its axial line conllinear.
The radius of described second connecting hole 16 is greater than the radius of described first connecting hole 15.
Be fixed on by dental lamina in described U-lag 12, the dental lamina base of oil drilling tools dismounting facility is fixing on the piston rod by fixing hole 14.
Above the embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the invention scope change and improve, and all should still belong within this patent covering scope.
