Abstract
The utility model provides a combined drilling and countersinking cutter which is composed of a body, a drill bit, a countersinking bit cutter, fastening screws, etc. The utility model is characterized in that a rotating shaft [4], a negative countersinking bit cutter [5] and the separate type drill bit [6] are arranged on the body [1], wherein the rotating shaft [4] extends from the inside of a circular arc groove by centrifugal force; the negative countersinking bit cutter [5] is returned by inertial force; the separate type drill bit [6] is connected with the body through screw threads. The utility model is especially suitable for numerical control machines and machining center machines in situations with requirements for hole drilling and positive and negative countersinking panels in the machining of box body parts. The utility model has the advantages of easy operation, high efficiency and labor saving.
Description
The utility model relates to a kind of cutter, is specially adapted to the occasion that box parts has the requirement of positive and negative ream disk.
Holed at box parts in the past, during spot facing; often to divide multiple working procedure to finish; especially in processing shown in accompanying drawing 1 during part; generally be first boring, plane on the forward ream again; shutdown is loaded onto anti-countersink by dimensional requirement; again lower plane is processed (anti-ream disk), unloaded cutter again, whole knife bar, cutter are withdrawed from, so process is numerous and diverse, need two people to cooperate on drilling machine simultaneously finishes.So non-cutting time is long in whole process, labour intensity is big, efficient is low.
The purpose of this utility model is to overcome above-mentioned shortcoming exactly, provides a kind of combined type easy to operate, that efficient is high, non-cutting time is short to bore countersink tool.
The purpose of this utility model is achieved in that
A kind of combined type bores countersink tool, is made up of body, drill bit, countersink and trip bolt etc., it is characterized in that being equipped with on the body 1 around the shaft 4 and in arc groove, stretch out by centrifugal force, the anti-countersink of returning by inertia force 5 and with the separate type drill bit 6 of cutter hub usefulness thread connection.
Now the utility model is described in further detail in conjunction with Figure of description:
Fig. 1 is the front view of one of the utility model embodiment, and wherein 1 is cutter hub, 2 trip bolts, 3 positive countersinks, 4 rotating shafts, 5 anti-countersinks, 6 drill bits.
The A-A cutaway view of Fig. 2 present embodiment, O
1Be the central point of body 1, O is the eccentric point of anti-countersink 5.
Fig. 3 is for needing processing zero partial sectional view.
Fig. 4 is a part processing work step schematic diagram shown in Figure 1, and a. boring, the positive spot facing of b., cutter are done forward (be clockwise direction, down with) rotation, and the anti-spot facing of c., cutter are made oppositely (counterclockwise promptly, down with) and rotated.
The utility model is like this work; main shaft band cutter is rotated in the forward, and the main shaft drilling rod of holing earlier down continues mobile, plane on the positive ream; shut down; main shaft counter-rotating, anti-countersink 5 be around the shaft 4 revolutions from arc groove under centrifugal action, and cutter head stretches out; main shaft moves up (cutter also and then upwards) can anti-spot facing; shut down at last, forward, anti-countersink 5 utilizes inertia force to return in the groove. Withdraw from whole cutter, all process is finished at once.
Embodiment: Fig. 2 is one of embodiment of the present utility model.
Advantage of the present utility model: time processing can be finished box parts boring, spot facing, anti-ream lower plane, having saved twice is installed and changes the cutter time, changing a people into by former two people operation can operate, former three work steps are processed a present work step and can be finished, and have namely reduced non-cutting time and saved again the labour, have been specially adapted to the occasion that machining center Digit Control Machine Tool or other lathe have boring, positive and negative spot facing to need.
Claims (6)
1, a kind of combined type bores countersink tool, form by body, drill bit, countersink and trip bolt etc., it is characterized in that on the body [1] [4] being housed around the shaft stretches out by centrifugal force in arc groove, the anti-countersink of returning by inertia force [5] and with the separate type drill bit [6] of body thread connection.
2, cutter according to claim 1, the OR undersized that it is characterized in that anti-countersink [ 5 ] is in the size OP of body [ 1 ].
3, cutter according to claim 1, the angle beta that it is characterized in that adorning on the body [ 1 ] arc groove of anti-countersink [ 5 ] should be greater than 90 °.
4, the cutter according to claim 1 is characterized in that drill bit [ 6 ] and body [ 1 ] are separate type, and [ 6 ] are thread connection with [ 1 ].
5, according to claim 1,4 described cutters, it is characterized in that it is left-hand thread that drill bit [ 6 ] connects screw thread with body [ 1 ].
6, the cutter according to claim 1 is characterized in that body [ 1 ] goes up shank portion [ A ] and can make staight shank or two kinds of forms of taper shank.
