Abstract
The utility model discloses a kind of floating and draw reamer, comprising floats draws reamer head (1), trundle (2) and cutter holder (3), and described floating draws reamer head (1) to be installed on cutter holder (3) by trundle (2).Described floating draws reamer head (1) to have cutter pilot to divide and cutting edge, and cutter pilot divides and is positioned at cutting edge rear portion.Described floating draws reamer head (1) also to comprise handle of a knife and chip area, and the little ratio of the transition portion diameter between cutting edge and handle of a knife is in the little 2 ~ 5mm of chip area base diameter.Described floating drawing on the handle of a knife of reamer head (1) has aperture.Of the present utility model floating draws that reamer chip resistance is good, stable cutting, can solve the mechanical deep hole machining problem of small lot batch manufacture preferably.
Description
Technical field
The utility model belongs to industrial knife technical field, and particularly a kind of floating draws reamer.
Background technology
During machining deep hole, there is cutter poor rigidity, chip removal difficulty and the not problem such as easy heat radiation, and then affect the crudy of deep hole, when production lot is larger, special equipment and technological equipment can be selected to solve deep hole machining problem.When little, the with short production cycle and workpiece size precision height of batch processed, part processing is main based on common apparatus and technological equipment, and special equipment and technological equipment should not be used to solve deep hole machining problem.
Utility model content
Problem to be solved in the utility model is to provide a kind of floating and draws reamer, and this floats and draws reamer can solve the mechanical deep hole machining problem of small lot batch manufacture.
Of the present utility model floating draws reamer, and comprising floats draws reamer head, trundle and cutter holder, and described floating draws reamer head to be installed on cutter holder by trundle.Described floating draws reamer head to have cutter pilot to divide and cutting edge, and cutter pilot divides and is positioned at cutting edge rear portion.
Another kind as technique scheme improves, described float draw reamer head also to comprise handle of a knife and chip area, the little ratio of the transition portion diameter between cutting edge and handle of a knife in chip area base diameter little ~ 5mm.
Another kind as technique scheme improves, and described floating drawing on the handle of a knife of reamer head has aperture.
Of the present utility model floating draws that reamer chip resistance is good, stable cutting, can solve the mechanical deep hole machining problem of small lot batch manufacture preferably.
Accompanying drawing explanation
Fig. 1 be the utility model float draw reamer structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the one that the utility model proposes is floated and draws reamer to be described in detail.
As shown in Figure 1, of the present utility model floating draws reamer, and comprising floats draws reamer head 1, trundle 2 and cutter holder 3, and described floating draws reamer head 1 to be installed on cutter holder 3 by trundle 2.Described floating draws reamer head 1 to have cutter pilot to divide and cutting edge, and cutter pilot divides and is positioned at cutting edge rear portion.Described floating draws reamer head 1 also to comprise handle of a knife and chip area, and the little ratio of the transition portion diameter between cutting edge and handle of a knife is in the little 2 ~ 5mm of chip area base diameter.Described floating drawing on the handle of a knife of reamer head 1 has aperture.
Drawing the cutter holder 3 of reamer through inner hole of workpiece by floating, then workpiece being contained on self-centering chuck with floating to draw together with reamer, clamping cutter holder 3 with the drill point on tail stock.After starting lathe, pull reamer with tailstock.
Diameter is greater than to the deep hole of 10mm, the interior spray type of cooling can be adopted, improve the chip resistance of cutting.
