Circumferentially Central Symmetry sets the arc cutter head for raising up.This kind of reverse countersink can realize that reverse ream is put down, but exist as follows
Problem:One is can only reversely using for cutter, and processing mode is single；Two is that knife bar can not be adjusted with the link position of tool rest, is led
The use of countersink is caused to be restricted.
Utility model content
To overcome deficiency of the prior art, the utility model provides a kind of countersink for the end face processing that drills.
To achieve the above object, the technical solution adopted in the utility model is as follows：A kind of ream for the end face processing that drills
Knife, including knife bar, cutter head and cutter head retaining mechanism, the knife bar include what the first knife bar being connected with main shaft and cutter head were connected
Second knife bar, first knife bar and the second knife bar be detachably connected and the first knife bar the diameter with diameter greater than the second knife bar, should
Second knife bar is provided with cutter head mounting hole, and the cutter head penetrates in the cutter head mounting hole of the second knife bar and solid by retaining mechanism
It is fixed.
Further, the first knife bar end face is provided with axially extending mounting groove, outer wall and is provided with the lock connected with mounting groove
Tieholen, second knife bar is penetrated in mounting groove and fastened by clamping screw.
Further, the second knife bar is cylindrical structural, second and knife bar insertion one section of mounting groove is provided with spacing grooving,
The mounting groove inwall of first knife bar is adapted with the second knife bar outer wall for being provided with spacing grooving, locking hole is cut relative to spacing
Groove is arranged.
Further, the second knife bar is provided with the end face of cutter head mounting hole side that to be provided with one interior with what cutter head mounting hole was connected
Hole, the retaining mechanism is to wear in endoporus and extend to the bolt in cutter head mounting hole.
Further, cutter head is stretched into cutter head mounting hole and extends radially through the second knife bar.
From above-mentioned to description of the present utility model, compared with prior art, being used for that the utility model is provided is used
The countersink of drilling end face processing, can carry out the flat processing of ream to Workpiece boring end face, when the positive inconvenience processing of countersink or workpiece are turned over
Turn inconvenience when, by change machine direction realize drilling end face process, this kind be used for drill end face processing countersink it is easy to use,
Preparation cost is low, high in machining efficiency, is applicable to various substandard workpiece, and the product design of processing is attractive in appearance.
Brief description of the drawings
Fig. 1 is structural representation of the utility model for the countersink of the end face processing that drills.
Fig. 2 is structural representation of the utility model for the knife bar of countersink second of the end face processing that drills.
Fig. 3 is schematic cross-section of the utility model for the knife bar of countersink second of the end face processing that drills.
Specific embodiment
Below by way of specific embodiment, the utility model will be further described.
Shown in reference picture 1,2,3, a kind of countersink for the end face processing that drills, including knife bar 1 and cutter head 2 and cutter head locking
Mechanism 3；
Knife bar 1 includes the first knife bar 11, the second knife bar 12 and clamping screw 13, and first knife bar 11 is connected with main shaft, the
Two knife bars 12 are connected with cutter head 2, and the diameter with diameter greater than the second knife bar 12 of the first knife bar 11, the end face of the first knife bar 11 is provided with
Axially extending mounting groove 111, outer wall is provided with the locking hole 112 connected with mounting groove 111.
The knife bar of second knife bar 12 second is cylindrical structural, and its one end is penetrated in mounting groove 111 and passes through clamping screw 13
Fastening, insertion one section of mounting groove 111 is provided with spacing grooving 121, the inwall of mounting groove 111 be provided with the second of spacing grooving 121
The outer wall of knife bar 12 is adapted, and locking hole 112 is arranged relative to spacing grooving 121, realizes the first knife bar 11 and the second knife bar 12
It is detachably connected；The other end of second knife bar 12 is provided with cutter head and installs 122 holes, is provided with the end face of the side of cutter head mounting hole 122
