Abstract
The utility model discloses a plane countersink device which is characterized in that a blade is installed at the tail end of a cutter bar through a flat key and is fastened through a nut, the upper end of the cutter bar is sequentially provided with a thrust bearing and a bearing base, and the lower portion of the bearing base is sequentially connected with a spring and a spring base. The cutter bar is further provided with a bushing, the bushing is located above the blade, and the upper portion of the thrust bearing is further connected with an adjusting nut used for adjusting the thrust bearing to move up and down. On the condition that the spatial position of a machining site is limited, the plane countersink device can be used for carrying out countersink operations on the lower end face of an orifice; the plane countersink device is simple in structure, easy and convenient to operate, little in labor intensity and high in adaptability.
Description
Technical field
The utility model relates to a kind of machining equipment, particularly a kind of plane countersink device.
Background technology
The object of spot-facing is the perpendicularity in order to ensure aperture and centerline hole, so that the part position being connected with hole is correct, connects reliable.Connection nose end ream at workpiece goes out cylindricality or tapered counterbore, imbeds in hole relevant part is coupled together with counter-sunk screw, makes outward appearance neat, rigging position compactness.By aperture flattening end surface, and vertical with centerline hole, can make the end face of connecting bolt (or nut) and connector keep good contact.
In shipbuilding engineering, some workpiece need to carry out spot-facing processing at the scene, and on-the-spot locus is more limited, and on-the-spot locality condition is also complicated, is difficult for carrying out the plane machining of nose end.Such as main frame and lower surface, gear-box reamer bolt hole need ream flat, vertical with bolt to ensure lower surface, but main frame and gear cage base locus are limited, and large machining tool cannot enter Working position.And the similar size range that needs machine to add is large, precision prescribed is high, and existing countersink device cannot meet the demands.
Summary of the invention
It is a kind of simple in structure, easy and simple to handle that the purpose of this utility model is to provide, and labour intensity is little, the plane countersink device that applicability is strong.
For achieving the above object, plane countersink device of the present utility model, it is characterized in that: comprise blade, knife bar, thrust bearing, bearing block, spring and spring base, blade is arranged on knife bar end by flat key, and with fastening nuts, knife bar upper end is provided with thrust bearing, bearing block successively, and bearing block below is connected with spring, spring base in turn.
Described knife bar is also provided with lining, and lining is positioned at blade top.
Described thrust bearing top is also connected with the adjusting nut that regulates thrust bearing to move up and down.
Described knife bar top is fixing hex nut.
Substantive distinguishing features of the present utility model and progress are:
The application's plane countersink device, for the limited condition in processing site locus, for the spot-facing operation of lower surface, aperture, adjust the spring force of spring by thrust bearing with adjusting nut, make blade be close to machined surface under the effect of spring force, the hex nut on swivel knife carrier top can be with cutting blade rotation to carry out machining.Use thrust bearing, effectively reduce friction, reduce labour intensity, utilize spring force that blade and machined surface are fitted tightly, in process, stressed even guarantee machined surface is vertical with hole.Lining, for the location in hole, can be selected according to the diameter of machining hole the lining of different size, and applicability is strong.This plane countersink apparatus structure is simple, easy and simple to handle, and labour intensity is little, and applicability is strong.

Detailed description of the invention
Below in conjunction with accompanying drawing, enforcement structure of the present utility model is described.
Plane countersink device of the present utility model, blade 10 is arranged on knife bar 7 ends by flat key, and with fastening nuts, knife bar 7 upper ends are provided with thrust bearing 3, bearing block 4 successively, and bearing block 4 belows are connected with spring 5, spring base 6 in turn.Knife bar 7 is also provided with lining 8, and lining 8 is positioned at blade 10 tops.Thrust bearing 3 tops are also connected with the adjusting nut 2 that regulates thrust bearing 3 to move up and down.Knife bar 7 tops are fixing hex nut 1.
The operation principle of this plane countersink device is described below in conjunction with accompanying drawing and the course of work:
First knife bar 7 and lining 8 are placed in hole to be processed, then with flat key and nut, blade 10 are anchored on knife bar 7.Thrust bearing 3 is connected with bearing block 4, and bearing block 4 is connected with spring 5, by turning adjusting nut 2, promotes thrust bearing 3, makes it holddown spring 5.Spring 5 is connected with spring base 6, between spring base 6 and blade 10, is fixed with workpiece pedestal 9, between spring base 6 and workpiece pedestal 9, is also placed with pad.The lower surface of workpiece pedestal 9 is machined surface 11, and blade 10, under the effect of spring force, fit tightly, and machined surface is perpendicular to hole with machined surface 11.
With the hex nut 1 on handle or other instrument swivel knife carrier 7 tops, drive knife bar 7 and blade 10 rotate together, blade 10 carries out machining to machined surface 11 under the effect of spring force, and can ensure to make machined surface 11 after processing perpendicular to hole.
Use thrust bearing 3, can effectively reduce friction, reduce labour intensity, utilize spring force that blade 10 and machined surface 11 are fitted tightly, in process, stressed even guarantee machined surface is vertical with hole.Lining 8, for the location in hole, can be selected according to the diameter of machining hole the lining 8 of different size, makes this plane countersink device applicability strong.
