Abstract

The utility model relates to the field of cutters, and discloses an inversion facing cutter for screw holes. A cutter clamp end of a facing cutter arbor is clamped on a drilling chuck, a positioning rod is sleeved on a bolt hole of a workpiece, a blade is locked on a facing cutter sleeve by a bolt and a fixing block, and the facing cutter sleeve is sleeved on a cutter assembling rod of the facing cutter arbor. Due to the technical scheme, the inversion facing cutter consisting of the blade, the blot, the fixing block and the facing cutter sleeve is positioned below the bolt hole of the workpiece, accordingly, a counter bore can be processed in an inversion manner, the workpiece is positioned conveniently, and production cost is saved.

Description

A kind of screw upside-down mounting ream is put down cutter
Technical field
The utility model relates to the cutter field, is the flat cutter of a kind of screw upside-down mounting ream.
Background technology
In the blower fan process; When dividing flange to connect in last second casting workpiece; The good flange connection holes of subdrilling; But flange end machined surface should could be locked the two kinds of methods that adopt usually by the flat back of ream bolt: a kind of is that the plane after the polishing is crude, crooked with angle grinding machine manual grinding, its workload is big again.Another kind method is on knife bar, inserts a white steel knife bar and carries out the flat processing of ream, and when machine tool chief axis rotated, because knife bar rocks, white steel knife bar frangible was not durable not only dangerous but also time-consuming again.Above ream quadratic method does not reach quality requirement, and screw rod also is difficult to locking, more can not satisfy requirement of products.
Summary of the invention
The purpose of the utility model is to provide a kind of simple in structure, and the screw upside-down mounting ream of long service life is put down cutter, and machining accuracy can satisfy requirement of products.
The technical scheme of the utility model is: the tool mounting end clamping of the flat knife bar of ream is on the boring chuck; Backstay portion is sleeved on the workpiece bolt hole; Blade is locked on the flat broach shell of ream through bolt and fixed block, and the flat broach shell of ream is sleeved in the cutter Assembly rail portion of the flat knife bar of ream.
Owing to adopted technique scheme, the flat cutter of upside-down mounting ream that blade, bolt, fixed block, the flat broach shell of ream constitute be positioned at the workpiece bolt hole below, but this makes counterbore upside-down mounting processing, is convenient to the location of workpiece, has practiced thrift production cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
In the drawings: 1, boring chuck; 2, the flat knife bar of ream; 3, backstay portion; 4, blade; 5, fixed block; 6, bolt; 7, cutter Assembly rail portion; 8, the flat broach shell of ream; 9, bolt hole; 10, tool mounting end.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
In Fig. 1; Tool mounting end 10 clampings of the flat knife bar 2 of ream are on boring chuck 1; Backstay portion 3 is sleeved on the workpiece bolt hole 9, and blade 4 is locked on the flat broach shell 8 of ream through bolt 6 and fixed block 5, and the flat broach shell 8 of ream is sleeved in the cutter Assembly rail portion 7 of the flat knife bar 2 of ream.
Backstay portion 3 materials 45, high-frequency quenching has been strengthened the hardness of backstay portion, has increased service life; Backstay portion 3 is 0.1~0.6mm with the monolateral gap of workpiece bolt hole 9, has improved processing back counterbore precision; The flat cutter of upside-down mounting ream that blade 4, bolt 6, fixed block 5, the flat broach shell 8 of ream constitute is positioned at below the workpiece bolt hole 9, and this can process counterbore in a upside-down mounting, is convenient to the location of workpiece, has practiced thrift production cost.Therefore, this novel screw upside-down mounting ream paperback put have that cost is low, long service life, processing counterbore precision are high, the characteristics of being convenient to the location of workpiece.
