Description
Technical field
The utility model belongs to drilling tool technical field, and in particular to a kind of counter boring for processing sunk head rivet hole
Bore.
Background technology
Existing universal socket drill includes the lead column, cutter hub and the connection handle that are sequentially connected from front to back, the front portion of cutter hub
The blade for cutting is fixed with, escape is provided between lead column and blade, so result in relatively thin work piece easy
It is stuck in escape, lead column does not have guiding function yet.In addition, processing sunk head rivet hole is to morpheme size higher, the ream of requirement
After socket drill is using a period of time, blade needs to carry out reconditioning or replacing, and the structure of existing socket drill is not easy to positioning and fixes, and makes
Cannot reconditioning and accurate replacing into old blade.
Utility model content
Based on the deficiencies in the prior art, the utility model provides a kind of socket drill for processing sunk head rivet hole.
To achieve these goals, the technical scheme that the utility model is taken is as follows：
A kind of socket drill for processing sunk head rivet hole, including lead column, cutter hub and the company being sequentially connected from front to back
Handle is connect, and the longitudinal center line of lead column, cutter hub and connection handle is respectively positioned on same straight line, the middle part of the cutter hub is in polished rod
Shape, and cutter hub front portion and rear portion be in the conical surface, cutter hub front portion the conical surface at be fixed with least two for cut blade, blade
Front end extend to the rear portion of lead column, the center of lead column front end face and the center of connection handle rear end face are equipped with center
Hole, two longitudinal center lines of centre bore are located along the same line with the longitudinal center line of cutter hub.
Preferably, the connection handle external peripheral surface is provided with screw thread, is provided between connection handle and the cutter hub rear portion conical surface and moved back
Cutter groove.
Preferably, mounting hole is provided with the middle part of cutter hub, the longitudinal center line of the mounting hole is in the axial direction of cutter hub
Heart line.
Preferably, the lead column, cutter hub and connection handle are formed in one.
The utility model is no longer limited by work piece thickness, it is possible to achieve processing a diameter of more than 2.5 millimeters sink
Head rivet hole；The counterbore size that processes, the accuracy of form and position are high, surface smoothness is good；When old blade reconditioning or replacing, front and back ends
Centre bore be easy to the Set and Positioning of socket drill, improve the utilization rate of socket drill, reduce the use cost of client.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation in sunk head rivet hole.
Specific embodiment
As shown in figure 1, a kind of socket drill for processing sunk head rivet hole, including the lead column being sequentially connected from front to back
2nd, cutter hub 4 and connection handle 6, the lead column 2, cutter hub 4 and connection handle 6 are formed in one, and lead column 2, cutter hub 4 and connection handle
6 longitudinal center line is respectively positioned on same straight line.The middle part of the cutter hub 4 is shaft-like in light, and the front portion and rear portion of cutter hub 4 are in
The conical surface；The middle part of cutter hub 4 is provided with mounting hole 5, the longitudinal center line of the longitudinal center line of the mounting hole 5 perpendicular to cutter hub 4；Knife
Be fixed with the anterior conical surface of body 4 at least two for cut blade 3, the front end of blade 3 extends to the rear portion of lead column 2.Institute
State the external peripheral surface of connection handle 6 to be provided with for installing the screw thread for connecting, be provided between connection handle 6 and the rear portion conical surface of cutter hub 4 and moved back
Cutter groove 7.The center of the front end face of lead column 2 and the center of the rear end face of connection handle 6 are equipped with centre bore 1, two centre bores 1
Longitudinal center line of the longitudinal center line with cutter hub 4 is located along the same line.
As shown in Fig. 2 in thickness to process sunk head rivet hole on the work piece of h, the sunk head rivet hole includes mutual
The cone shaped countersink and cylindrical hole of connection, a diameter of D of the bellmouth port, the cone angle of bellmouth is β, the diameter of cylindrical hole
It is d, sunk head rivet is installed because sunk head rivet hole is used to coordinate, so higher to the dimension precision requirement of D, β and d.
When work piece thickness h is smaller, extend to the rear portion of lead column 2 due to the front end of blade 3, and lead column 2 with
Escape is not provided between cutter hub 4, such work piece will not be stuck, and lead column 2 can also function well as guiding function.When
After socket drill described in the utility model is using a period of time, when blade 3 needs reconditioning or changes, can be by socket drill forward and backward two
The centre bore 1 at end carries out Set and Positioning, limits the axial freedom of socket drill, adds on the special equipment used by prior art
Work, limits the radial direction free degree, it is ensured that the dimensional accuracy of blade 3, so make cone shaped countersink D and β dimensional accuracies are high, surface light
Cleanliness is good.
