Abstract
A kind of full-rotating drill top layer bracket disk, including be D by one piece of steel plate addition outer diameter, the circular ring shape disk body that internal diameter is d, the upper end of circular ring shape disk body outer surface is machined with the conical surface that coning angle is 2 α, the upper end of inner surface is also machined with circular conical surface, is circumferentially uniformly machined with multiple axially extending bores on the annulus disk body.Using the structure of shape and optimised, it is designed using reasonable welding groove, it solves the problems, such as that unreasonable groove design, influence welding efficiency is welded and fixed, easily because deforming or cannot generate welding defect due to complete penetration in inner cylinder and outer cylinder, improves slewing drilling machine top layer bracket disk overall stiffness, intensity.Its structure is simple, and bearing capacity is strong, at low cost using reliable.
Description
Technical field
The utility model relates to a kind of Special disc, especially a kind of top suitable for full-rotating drill driving device
The disk of top layer bracket.
Background technique
Disk is an important part in full-rotating drill driving device on top layer rack platform, it is fixedly mounted on top
In layer rack platform between inner cylinder and outer cylinder, important stabilization and invigoration effect are played to total, while it is also
The installation foundation of pivoting support.There is also following main insufficient for disk in existing full-rotating drill top layer rack platform: first is that
For being welded and fixed with inner cylinder and outer cylinder groove design it is unreasonable, influence welding efficiency, easily because deformation or cannot be complete
Penetration and generate welding defect；Second is that with corresponding inner cylinder, outer cylinder and pivoting support seat etc. in shape and size on
With unreasonable, it is unreliable to cause to be fixedly connected, or even influences the overall stiffness and intensity of top layer platform.
Summary of the invention
Technical problem: the purpose of the utility model is to overcome the shortcoming in prior art, provide a kind of structure it is simple,
The full-rotating drill top layer bracket disk that bearing capacity is strong, effect improves, intensity is high
Technical solution: the full-rotating drill top layer bracket disk of the utility model, including be by one piece of steel plate addition outer diameter
D, internal diameter is the circular ring shape disk body of d, and the upper end of circular ring shape disk body outer surface is machined with the conical surface that coning angle is 2 α, inner surface
Upper end is also machined with circular conical surface, is circumferentially uniformly machined with multiple axially extending bores on the annulus disk body.
The outer diameter D of the circular ring shape disk body is determined according to the range of the internal diameter of outer cylinder and tolerance h12 in top layer bracket.
The internal diameter d of the circular ring shape disk body is determined according to the range of the outer diameter of inner cylinder and tolerance H12 in top layer bracket.
2 α of coning angle in the circular ring shape disk body outer surface upper cone face is 90 °, and the axial height of the conical surface is 20mm.
The coning angle in the circular ring shape disk body inner surface upper cone face is 90 °, and the axial height of the conical surface is 20mm.
The multiple axially extending bores circumferentially uniformly processed are 36.
The utility model has the advantages that by adopting the above-described technical solution, the utility model is answered using the structure of shape and optimised
Designed with reasonable welding groove, solve inner cylinder and outer cylinder be welded and fixed groove design is unreasonable, influence welding efficiency,
Yi Yin deformation or cannot completely penetration and lead to the problem of welding defect, it is integrally rigid to improve slewing drilling machine top layer bracket disk
Degree, intensity.Its structure is simple, and bearing capacity is strong, at low cost using reliable, has wide applicability.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is A-A partial cutaway view.
Specific embodiment
One embodiment of the utility model is further described with reference to the accompanying drawing:
As shown in Figure 1, a kind of dedicated full-rotating drill top layer bracket disk, be mainly D by one piece of steel plate addition outer diameter,
Internal diameter is the circular ring shape disk body of d, and the outer diameter D of the circular ring shape disk body is according to the internal diameter of outer cylinder in top layer bracket and tolerance h12
Range determine；The internal diameter d of the circular ring shape disk body according to the range of the outer diameter of inner cylinder and tolerance H12 in top layer bracket come
It determines.The upper end of circular ring shape disk body outer surface is machined with the conical surface that coning angle is 2 α, circular ring shape disk body outer surface top
2 α of coning angle of circular conical surface is 90 °, and the axial height of the conical surface is 20mm.The upper end of the circular ring shape disk body inner surface also processes
There is circular conical surface, the coning angle in circular ring shape disk body inner surface upper cone face is 90 °, and the axial height of the conical surface is 20mm.Described
Multiple axially extending bores are circumferentially uniformly machined on annulus disk body；The multiple axially extending bores circumferentially uniformly processed are 36
It is a.
