Description
Technical field
A kind of rough boring cutter is the utility model is related to, specifically a kind of idle pulley seat endoporus combination rough boring cutter, belongs to boring cutter
Equipment technical field.
Background technology
At present, the two grades of hole size required precisions of idle pulley seat are very high, and relative axiality requires also very high.Idle pulley seat
Surplus and position control before inner hole finish-boring is particularly important.In the prior art, can only disposably on lathe clamping one boring
Knife completes the heavy boring of one grade of endoporus, completes to change after the heavy boring of one grade of endoporus another rough boring cutter is carried out the thick of another grade of endoporus again
Boring.And lathe can move repeatedly in exchanging knives process, lathe is to have certain deviation when moving repeatedly, during so as to cause right boring hole
Deviation occurs for position, causes product quality unqualified.The mismatch error of handle of a knife and main shaft in tool changing process be present, repeatedly
Tool changing and multiple processing efficiency also can be very low.
The content of the invention
In place of the purpose of this utility model is to overcome above-mentioned deficiency, so as to provide a kind of idle pulley seat endoporus combination heavy boring
Knife, the heavy boring processing of two grades of endoporus of idle pulley seat can be disposably completed, reduces the accumulated error in process, improves production effect
Rate.
According to technical scheme provided by the utility model, a kind of idle pulley seat endoporus combination rough boring cutter include blind rivet, rear handle of a knife,
Middle handle of a knife, preceding handle of a knife, the first heavy boring blade, adjustable cutter holder and the second heavy boring blade, rear handle of a knife rear end are connected through a screw thread drawing
Nail, it is characterized in that：Middle handle of a knife front and back end connects preceding handle of a knife and rear handle of a knife respectively, and preceding handle of a knife front end is provided with the first cutter groove, and first
The first heavy boring blade of fastening is connected by the first holding screw in cutter groove；Middle handle of a knife front end is provided with the second cutter groove, the second cutter groove
Interior to connect adjustable cutter holder by housing screw, adjustable cutter holder front end connects the second heavy boring blade by the second holding screw, adjustable
Cutter holder rear end is connected through a screw thread regulating bolt.
Further, rear handle of a knife, middle handle of a knife and preceding handle of a knife are integrally formed.
Further, rear handle of a knife is cone, and middle handle of a knife and preceding handle of a knife are cylinder, before the diameter of middle handle of a knife is more than
The diameter of handle of a knife.
Further, the head of regulating bolt is provided with adjustment hole.
Compared with the prior art the utility model has advantages below：
The utility model is simple in construction, compact, reasonable, can disposably complete the heavy boring processing of two grades of endoporus of idle pulley seat,
Save tool change time and part process time, reduce the accumulated error in process, improve production efficiency；Fixed at one thick
Adjustable rough boring cutter holder at boring cutter folder one, can process different hole sizes respectively；Adjustable rough boring cutter holder root passes through set screw
Adjustment control step is the distance between cylindrical, so as to meet different process requirements.
Brief description of the drawings
Fig. 1 is the utility model front view.
Description of reference numerals：Handle of a knife, the cutter grooves of 5- first, 6- first are tight before handle of a knife, 3- centres handle of a knife, 4- after 1- blind rivets, 2-
Determine screw, the first heavy borings of 7- blade, 8- regulating bolts, 9- housing screws, 10- is adjustable cutter holder, the holding screws of 11- second, 12-
Two heavy boring blades, the cutter grooves of 13- second, 14- adjustment holes.
Embodiment
The utility model will be further described with reference to the embodiment in accompanying drawing below：
As shown in figure 1, the utility model mainly includes blind rivet 1, rear handle of a knife 2, middle handle of a knife 3, preceding handle of a knife 4, the first heavy boring
Blade 7, the heavy boring blade 12 of adjustable cutter holder 10 and second.
The middle front and back end of handle of a knife 3 connects preceding handle of a knife 4 and rear handle of a knife 2, rear handle of a knife 2, middle handle of a knife 3 and preceding handle of a knife 4 one respectively
Body formed, the rear rear end of handle of a knife 2 is connected through a screw thread blind rivet 1.
Handle of a knife 2 is cone after described, and middle handle of a knife 3 and preceding handle of a knife 4 are cylinder, before the diameter of middle handle of a knife 3 is more than
The diameter of handle of a knife 4.
The front end of preceding handle of a knife 4 is provided with the first cutter groove 5, passes through the first holding screw 6 connection fastening first in the first cutter groove 5
