Abstract
The utility model relates to a mechanical machining cutter, in particular to a deep hole drilling cutter for graphite parts; the deep hole drilling cutter is characterized in that the deep hole drilling cutter also comprises a first flat drill, a first flat drill support, a second flat drill and a second flat drill support, wherein the first flat drill is arranged at the foremost end of a cutter body, the first flat drill support is arranged above the flat drill; the second flat drill which is used for machining a stepped hole is arranged above the first flat drill support; and the second flat drill support is arranged above the second flat drill. Compared with the prior art, the deep hole drilling cutter can be applied to a common lathe so that machined holes turn to be an auxiliary support for the follow-up machining, the effective suspension elongation of the cutter is effectively shortened, and the rigidity of the drill bit is intensified.
Description
[technical field]
The utility model relates to a kind of machining tool, specifically a kind of drilling deep hole cutter that is used for graphite parts processing.
[background technology]
Because the isostatic pressing formed graphite material is relative and metal material has intensity low, so in the graphite machined, there is cutting brisk.Under the situation of equal cutting load, the amount of feeding in the machining graphite cutting parameter and cutting depth usually can be selected several times of metal processing for use.So the deep hole machining of graphite all is a difficult problem of field of machining for a long time, though deep hole drilling machine collocation drill gun is a good solution.But the input of Special Equipment and cutter also is a no small expense.
[summary of the invention]
The purpose of the utility model is the deficiency that overcomes prior art, and the drilling deep hole cutter that provides a kind of design on engine lathe, to process the isostatic pressing formed graphite part is achieved the deep hole machining of isostatic pressing formed graphite part on engine lathe.
In order to achieve the above object; The utility model has designed a kind of graphite parts drilling deep hole cutter; The connecting portion that comprises blade and be connected the blade afterbody is characterized in that: also comprise blade first chit drill foremost, and first chit drill support that is positioned at first chit drill top; First chit drill supports the top for to be used for second chit drill of processing shoulder hole, and second chit drill support that is positioned at second chit drill top.
The diameter of said second chit drill is greater than the diameter of first chit drill.
Said first chit drill is consistent with the angle of taper of second chit drill.
The utility model is compared with prior art, and this gun drilling cutter can be used on the engine lathe, makes the hole that processes become the supplemental support of following process, has shortened the length that effectively overhangs of cutter greatly, has strengthened the rigidity of drill bit.
[description of drawings]
Fig. 1 is the structural representation of the utility model.
Referring to Fig. 1,1 is blade; 2 is that second chit drill supports; 3 is that first chit drill supports; 4 is connecting portion; 5 is first chit drill; 6 is second chit drill.
[specific embodiment]
Combine accompanying drawing that the present invention is done further describes at present.
Connecting portion as shown in Figure 1, that the utility model comprises blade and is connected the blade afterbody also comprises blade 1 first chit drill 5 foremost, and first chit drill support 3 that is positioned at first chit drill, 5 tops; It is second chit drill 6 that is used for processing shoulder hole that first chit drill supports 3 tops, and second chit drill support 2 that is positioned at second chit drill, 6 tops.Wherein, the diameter of second chit drill 6 is greater than the diameter of first chit drill 5.Before using this ladder depth drill, need on part, process the centre of location, and first chit drill 5 is consistent with the angle of taper of second chit drill 6 with centre drill.
The utility model is compared with prior art, and this ladder depth drill cutter can be used on the engine lathe, makes the hole that processes become the supplemental support of following process, has shortened the length that effectively overhangs of cutter greatly, has strengthened the rigidity of drill bit.
