Abstract
The invention discloses a deep hole boring cutter row. The deep hole boring cutter row comprises a cutter bar (1), a circular cutter disc (3) with cutter heads (2), and blades. The three or four cutter heads (3) are distributed on the cutter disc (3) in an annular array mode. The cutter blades (4) and the cutter heads (2) are fixed. The cutter disc (3) is arranged at the head end of the cutter bar (1). The deep hole boring cutter row has the advantages that the cutter heads which are distributed on the cutter disc in the annular array mode are selected, the bending moment of the cutter bar during cutting is balanced, and therefore the vibration of the cutter bar is reduced, the precision of machining products is improved, and meanwhile the service life of a cutter is prolonged.
Description
Technical field
The present invention relates to machine-building instrument, be specifically related to a kind of boring cutter row that is directed to deep hole boring.
Background technology
Press cutting movement mode and corresponding cutting edge shape, cutter can be divided three classes again.Universal cutter, as lathe tool, planing tool, milling cutter, boring cutter, drill bit, reamer, reamer and saw etc., forming tool, the blade of this class cutter has identical with workpiece to be machined section or approaches identical shape, as formed turning tool, shaping planing tool, form cutter, broaching tool, taper reamer and various threading tools etc.Generating tool is with the flank of tooth of generating machining gears or similar workpiece, as hobboing cutter, pinion cutter, gear shaver, bevel gear planing tool and bevel gear cutter dish etc.
Boring cutter is the one of cutting tool for boring, is generally circle handle, also has the larger workpiece user knife bar generally to see vertical car, the most frequently used occasion be exactly in hole process, reaming, profiling etc.But be not hole in can only processing, the outer fenestra of end face can be processed, and is not just such use traditionally.
Former Common boring cutter, is only provided with a cutter head, and in the time that boring depth exceedes 200mm, knife bar intensity is low, causes bore hole effect to decline; The degree of depth is excessively dark, thereby causes knife bar unbalance stress can cause that vibration causes the precise decreasing in the hole of processing, when serious, can cause product rejection, produces loss.
Summary of the invention
The deficiency of customer service background technology of the present invention provides a kind of vibration that is directed to deep hole boring few, the deep-hole boring blade row of stable mechanical property.
The invention provides following technical proposals: deep-hole boring blade row, comprise knife bar, be provided with circular cutterhead, the blade of cutter head, described cutter head circular array shape is distributed on described cutterhead, adopts such design can make cutter stressed evenly, and the quantity of described cutter head is three to four.Described blade and described cutter head fix; Described cutterhead is located at the head end of described knife bar.
Optimal case, the quantity of described cutter head is four.
Further, the material of described blade is high-speed steel.The material of described knife bar is spheroidal graphite cast-iron.
Beneficial effect of the present invention is, selected annular array shape to be distributed in the cutter head of described cutterhead, balance moment of flexure when knife bar cutting, thereby reduced cutter vibration of bar, improved the precision of converted products, the service life of also having improved cutter simultaneously.
Brief description of the drawings
Fig. 1 is the overall structure schematic diagram of boring cutter row of the present invention.
Fig. 2 is cutterhead of the present invention, cutter head structure schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further described.
In Fig. 1, Fig. 2: knife bar 1, cutter head 2, cutterhead 3, blade 4.
Deep-hole boring blade row, comprises knife bar 1, is provided with circular cutterhead 3, the blade 4 of cutter head 2, and cutter head 2 circular array shapes are distributed on described cutterhead 3, and the quantity of cutter head 2 adopts four.Blade 4 fixes with cutter head 2.Cutterhead 3 is located at the head end of described knife bar 1.
The material of blade 4 is M42 high-speed steel; The material of described knife bar 1 is spheroidal graphite cast-iron.
Operation instruction, this boring cutter row is for the endoporus of boring workpiece, and size and the edge of a knife of institute's boring endoporus match, and make the edge of a knife can complete smoothly whole working angles, do not need to add any cooling fluid in addition in the process of cutting; Reason be this boring cutter row blade adopt be high-speed tool steel, high-speed tool steel has higher resistance to elevated temperatures.
Claims (3)
1. deep-hole boring blade row, comprises knife bar (1), is provided with circular cutterhead (3), the blade (4) of cutter head (2), it is characterized in that, it is upper that described cutter head (2) circular array shape is distributed in described cutterhead (3), and the quantity of described cutter head (2) is three to four; Described blade (4) fixes with described cutter head (2); Described cutterhead (3) is located at the head end of described knife bar (1).
2. deep-hole boring blade row as claimed in claim 1, is characterized in that, the quantity of described cutter head (2) is four.
