Abstract
The utility model discloses a quick-change collet chuck free-pull-rod type main shaft. A screw is machined outside the main shaft, the main shaft further is provided with a conical hole accordant with the conical hole of a clamp, and a cutter is clamped by a locking nut, so that the quick assembling and disassembling is realized without a pull rod.
Description
Technical field
The utility model relates to a kind of machine tool chief axis, especially relates to milling machine series quick change collet chuck non pull rod type main shaft.
Background technology
Existing machine tool chief axis utilizes the pull rod screw rotation that anchor clamps are locked usually; But this method is taken a lot of work and pull bar damages easily, sacrifices Z axle height, is prone to produce vibration and this structure when running up owing to have more a junction position; Cause precise decreasing, rigidity variation, be not suitable for heavily cutting.
The utility model content
The purpose of the utility model is to solve prior art machine tool chief axis locking fixture and problems such as taking a lot of work of producing and pull bar damage easily, precise decreasing, rigidity variation, and a kind of improved non pull rod type quick change main shaft is provided.
According to above-mentioned purpose, the utility model provides a kind of quick change collet chuck non pull rod type main shaft, and said main shaft external process has screw thread, and said main shaft has the internal taper hole with collet chuck external taper unification, and said collet chuck is through nut check.
According to the embodiment of the utility model, said collet chuck is an ER series (being that internal taper is 8 °).
According to the embodiment of the utility model, said collet chuck is OZ series (is internal taper be 2 ° 52 ').
According to the above-mentioned quick change collet chuck non pull rod type main shaft of the utility model each side, can improve working (machining) efficiency, reduce connecting portion, improve precision, and can not sacrifice the processing stroke.
Description of drawings
Fig. 1 is the sketch map according to the quick change collet chuck non pull rod type main shaft 100 of an embodiment of the utility model.
The specific embodiment
Fig. 1 is the sketch map according to the quick change collet chuck non pull rod type main shaft 100 of an embodiment of the utility model.As shown in Figure 1, main shaft 100 outside cars have screw thread, and main shaft 100 has the internal taper hole with collet chuck external taper unification, and collet chuck is through nut check.
In one embodiment; Quick change collet chuck non pull rod type main shaft 100 collet chuck select the anchor clamps collet chuck of general on the market and easy buying for use; Like ER series (being that internal taper is 8 °), OZ series (be internal taper be 2 ° 52 '); Utilize existing collet chuck and nut, can therefore effectively shorten tool change time directly with the collet chuck fixing and locking.
Experiment showed, the main shaft 100 of selecting the utility model for use, used tool change time shortened in 20 seconds by existing 1-2 minute; It is in the 0.005mm that the beating of cutter promoted by existing 0.02mm.
Because the main shaft of the utility model is not sacrificed Z axle height, therefore can guarantee that lathe Z axle is at needed height.
Can see from above description; The main shaft that the utility model provides; Through main shaft self screw thread and existing collet chuck and nut the cutter fixing and locking need not extra pull bar, significantly reduced easily-consumed products, and reduced the uneven vibrations that produce of pull bar when main shaft runs up; Guarantee that lathe operates more safely, and reach higher machining accuracy.
Though described the utility model with reference to several exemplary embodiments, should be appreciated that used term is explanation and exemplary and nonrestrictive term.Because the utility model practical implementation and do not break away from the spirit or the essence of invention in a variety of forms; So be to be understood that; The foregoing description is not limited to any aforesaid details; And should in enclose spirit that claim limited and scope, explain widely, therefore fall into whole variations and remodeling in claim or its equivalent scope and all should be the claim of enclosing and contain
Claims (3)
1. a quick change collet chuck non pull rod type main shaft is characterized in that said main shaft external process has screw thread, and said main shaft has the internal taper hole with collet chuck external taper unification, and said collet chuck is through nut check.
2. quick change collet chuck non pull rod type main shaft as claimed in claim 1 is characterized in that, said collet chuck is an ER series, and said collet chuck internal taper is 8 °.
3. quick change collet chuck non pull rod type main shaft as claimed in claim 1 is characterized in that, said collet chuck is an OZ series, said collet chuck internal taper be 2 ° 52 '.
