Abstract
The utility model belongs to the technical field of automated machining, and particularly relates to a small cutter interface capable of allowing a cutter to be automatically replaced. The small cutter interface comprises a spindle connection portion, a tool magazine clamping portion and a tool installation portion, wherein the spindle connection portion and the tool installation portion are located at the two ends of the tool magazine clamping portion respectively, the spindle connection portion is composed of a conical handle shaped like a conical platform and a pull nail located at the small end of the conical nail, the large end of the conical handle is close to the tool magazine clamping portion, the cone angle of the conical handle is 10 degrees, and the diameter of the large end face of the conical handle ranges from 7mm to 14mm. The small cutter interface capable of allowing the cutter to be automatically replaced is simple in structure, automatic cutter replacement of a small high-velocity electric spindle and a small cutter can be achieved, rigidity connection of the small cutter interface and the spindle can be ensured, and high axial and radial positioning accuracy is achieved.
Description
Technical field
The utility model belongs to automation processing technique field, particularly a kind of small-sized cutter interface that can automatic tool changer.
Background technology
Along with the development of high speed machining, the miniature high-speed electricity main shaft with the little moment of torsion of high rotating speed has also obtained fast development, and the maximum speed of current domestic high-speed electric main shaft has reached 60000r/min, and main shaft external diameter can be less than 70mm, even reaches 40mm.The cutter interface that this type of electric main shaft is conventional is ER collet, and this interface pattern at present can only be for manual tool changing, and the full-automatic numerical control lathe for day by day rising, cannot meet the demands.In order to realize the automatic tool changer of small electrical main shaft, on market, also occurred adopting the mode of determining shank type tool changing, although this mode can be carried out automatic tool changer, tool changing poor reliability, and axially precision cannot guarantee.And for the research of automatic tool changer handle of a knife, be at present domesticly also confined to the stock size handle of a knife that traditional Digit Control Machine Tool is used, on market, not yet there is being exclusively used in the handle of a knife of high rotating speed small electrical main shaft.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of small-scale high rotational speed electricity main shaft handle of a knife is provided, and not only can realize automatic tool changer, can also guarantee and the rigid attachment of main shaft, realizes axial and radial accuracy preferably.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of small-sized cutter interface that can automatic tool changer, comprise main shaft connection part, tool magazine clamping part and Cutting tool installation manner portion, main shaft connection part and Cutting tool installation manner portion lay respectively at the two ends of tool magazine clamping part, main shaft connection part is comprised of with the blind rivet that is positioned at taper shank small end the taper shank of circular cone shape, the large end next-door neighbour of taper shank tool magazine clamping part, wherein the coning angle of taper shank is 10 degree, and the diameter range of taper shank large end face is 7～14mm.
Above-mentioned a kind of small-sized cutter interface that can automatic tool changer, the diameter of described taper shank large end face is 11.6mm.
Above-mentioned a kind of small-sized cutter interface that can automatic tool changer, described main shaft connection part, tool magazine clamping part and Cutting tool installation manner portion make by stainless steel.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple in structure, have realized the automatic tool changer of miniature high-speed electricity main shaft and small-sized cutter; Adopting cone angle is the taper shank structure of 10 degree, and while connecting with main shaft, the conical surface and end face are located simultaneously, can guarantee higher positioning precision.The utility model adopts stainless steel material manufacture to form in addition, has good rustless property, can under the processing environment of pure water, use applied range.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail.
As shown in Figure 1, a kind of small-sized cutter interface that can automatic tool changer of the present utility model, is made by stainless steel material, comprises blind rivet 1, taper shank 2 and tool magazine clamping part 3 and the Cutting tool installation manner portion 4 of main shaft connection part.Taper shank 2 and Cutting tool installation manner portion 4 are distributed in the two ends of tool magazine clamping part 3; Taper shank 2 is circular cone shape, and its cone angle alpha is 10 degree, and large end face diameter d is 11.6mm; In Cutting tool installation manner portion 4, be provided with external screw thread and Cutting tool installation manner endoporus; Blind rivet 1 is positioned at small end face one side of taper shank 2.
The utility model in use, first packs cutter in Cutting tool installation manner portion 4 into by collet and nut, forms a cutter module, now can pack in machine tool chief axis or tool magazine.While packing main shaft into, first the male cone (strobilus masculinus) of taper shank 2 is aimed to the internal taper hole of machine tool chief axis, then main shaft pulling claw is held blind rivet 1, under take-up device effect, the male cone (strobilus masculinus) of taper shank 2 and inner cone hole of main shaft are adjacent to, and the upper surface of cutter holding portion 3 and main shaft end face are adjacent to simultaneously, axially and radially equal accurate location of the present utility model now.During dismounting, main shaft pulling claw is released main shaft by the utility model under take-up device effect, and pulling claw opens, and now tool claw of tool storage is clamped to tool magazine clamping part 3, and the utility model is pulled down from main shaft, and then pack in tool magazine.
The utility model has been realized the automatic tool changer of miniature high-speed electricity main shaft and small-sized cutter, can eliminate the phenomenon that manual tool changing cutter length can not be consistent, and not only can guarantee good setting accuracy on work, and can greatly shorten the non-cutting time of processing.
