Abstract
Disclosed is a double-blade adjustable rough boring cutter, comprising a cutter body and a cutter bed. The double-blade adjustable rough boring cutter is characterized in that a guide rail is arranged at the end of the cutter body and the cutter bed can slide along the guide rail; a cutter bed adjusting bolt is arranged at one side face of the cutter bed; a cutter bed locking bolt disposed inside a kidney hole of the cutter bed fixedly connects the cutter bed with the cutter body; a butterfly gasket is arranged between the cutter bed locking bolt and the cutter bed. The guide rail is rectangular. Since the cutter bed and the cutter body are connected by the rectangular guide rail, so when adjusting, the cutter bed slides freely on the guide rail of the cutter body and will not swing to the left or right sides, thus the boring cutter is of good stability. The cutter bed locking bolt is matched with the butterfly gasket, so when adjusting, the locking bolt will not totally loosen, and the butterfly gasket will generates certain pre-tightening force to enable the cutter bed and the cutter body to keep in contact all the time, thus adjusting accuracy is high; the boring size can be adjusted through the adjusting bolt inside the cutter bed, ensuring that the adjusted desirable size will not be changed when the cutter bed is locked.
Description
Technical field
The utility model belongs to the metal cutting processing technique field, is specifically related to a kind of adjustable heavy boring cutter of twolip that is used for hole processing.
Background technology
Modular twolip heavy boring cutter is widely used in field of machining, compare with integral type single-blade heavy boring cutter, modular twolip heavy boring cutter has many advantages: because twolip heavy boring cutter in process, has two blades to participate in cutting simultaneously, stock-removing efficiency is higher; The radial load that acts on the cutting edge of two symmetries is cancelled out each other, and makes boring bar be difficult for producing vibration etc.
Although twolip heavy boring cutter has many advantages, the twolip heavy boring cutter of domestic present production just simply is pressed on two tool rests on the cutter hub with bolt, adjusts very inconveniently, even after adjusting, in compaction process, size also may change.Now has twolip heavy boring cutter to exist structure single, and poor stability is difficult for shortcomings such as adjustment, is difficult to satisfy the demand.
The utility model content
The purpose of this utility model is: provide a kind of and be easy to adjust, the twolip heavy boring cutter of good stability.
For achieving the above object, the technical scheme that adopts is: a kind of twolip is adjustable heavy boring cutter, comprise cutter hub and tool rest, it is characterized in that: described cutter hub end is equipped with guide rail, described tool rest can slide along described guide rail, one side of tool rest is equipped with tool rest and adjusts bolt, places the tool rest clamping screw in the described tool rest mounting hole that described tool rest is fixedlyed connected with described cutter hub.
Be equipped with the butterfly pad between described tool rest clamping screw and the described tool rest.
Described guide rail be shaped as rectangle.
Compared with prior art, connect with rectangular guideway between the utility model tool rest and the cutter hub, tool rest can be free to slide on the guide rail at cutter hub when adjusting, and can not swing, and stability is high; The tool rest clamping screw is furnished with the butterfly pad, and when adjusting, clamping screw need not be totally released, and the butterfly pad can produce certain pretightning force, tool rest is remained with cutter hub contact, and adjusts precision and improves greatly; Carry out boring by the adjustment screw in the tool rest and expand size adjusting, finish grind on tool rest clamping screw and adjustment surface, screw contact site, and when guaranteeing tool rest locking, the size of adjusting can not change.
Description of drawings
The utility model is described in further detail below by way of embodiments and drawings
Fig. 1 is the structural representation of modular twolip heavy boring cutter;
Fig. 2 is that the A of Fig. 1 is to structural representation.
Among the figure, the 1-cutter hub; The 2-tool rest is adjusted screw; The 3-tool rest; 4-butterfly pad; 5-tool rest clamping screw; The 6-blade; The 7-guide rail; The 8-mounting hole.
The specific embodiment
A kind of twolip is adjustable heavy boring cutter, as depicted in figs. 1 and 2, comprise cutter hub 1 and tool rest 3, it is characterized in that: described cutter hub 1 end is equipped with guide rail 7, described tool rest 3 can slide along described guide rail 7, the head of tool rest 3 is equipped with blade 6, and a side of tool rest 3 is equipped with tool rest and adjusts screw 2, places the mounting hole 8 interior tool rest clamping screws 5 of described tool rest 3 that described tool rest 3 is fixedlyed connected with described cutter hub 1.
Be equipped with butterfly pad 4 between described tool rest clamping screw 5 and the described tool rest 3.
Described guide rail 7 be shaped as rectangle.
During use, slip into heavy boring tool rest 3 in the guide rail of heavy boring cutter hub 1 along the guide rail direction, tool rest is adjusted screw 2 to screw in the screw of heavy boring tool rest 3 end faces, between tool rest clamping screw 5 and heavy boring tool rest 3, add butterfly pad 4 then, heavy boring tool rest 3 is pressed abd fixed on the heavy boring cutter hub 1 with tool rest clamping screw 5.When needs carry out size adjusting, as long as unclamp tool rest clamping screw 5, this moment, tool rest 3 can slide in the rectangular guideway 7 of cutter hub 1, but because the pretightning force effect of butterfly pad 4, the two still keeps close contact, do not get loose fully, so just can guarantee can size arbitrarily not changed when boring cutter is adjusted on lathe because of the effect of tool rest 3 gravity.The turn tool rest is adjusted screw 2, and it can withstand on the face of cylinder of tool rest clamping screw 5, tool rest 3 is outwards promoted, till adjusting to the size that needs.Then, tighten tool rest clamping screw 5, tool rest 3 is pressed on the cutter hub 1.Tool rest clamping screw 5 and tool rest are adjusted surface, screw 2 contact site and are finish grinded, and when guaranteeing tool rest locking, the size of adjusting can not change.
Claims (3)
