Abstract
The invention provides a center shaft capable of being fast mounted and demounted. The center shaft comprises a tail cone and a center head which are connected with each other, and a threaded part is arranged between the tail cone and the center head of the center shaft. The center shaft is particularly suitable for a center hole which is positioned, matched and mounted by Morse taper on a lathe or a grinder.
Description
Technical field
The invention provides in a kind of field of machining can the tail spindle of quick-detachment.
Background technology
In mechanical processing industry, lathe and grinding machine obtain as the machining tool that machining is the most general and apply the most widely.And on lathe and grinding machine, the frock of carrying out processing for accommodating workpiece is top.Generally toply comprise afterbody taper shank and head centre head.And general lathe is used for positioning the Morse's taper of all taking coordinated with top afterbody taper shank coordinates.After tail spindle afterbody taper shank one end being inserted the center hole of lathe, because Morse's taper coordinates, it does not produce displacement by closely cooperating with the inner conical surface of lathe center hole firmly.Therefore, when changing top, be difficult to pull down top fast.The invention provides a kind of Novel top spivot, make this top can dismantle fast on the basis ensureing Morse's taper location fit top.
Summary of the invention
To achieve the above object of the invention, the present invention is by the following technical solutions:
Can the tail spindle of quick-detachment, described tail spindle comprises connected tail bone and centre head, comprises threaded portion between the tail bone of described tail spindle and centre head, wherein, described tail spindle also comprise one with the flange of the threaded engagement of described tail spindle.
Alternatively, the tail bone of described tail spindle is substantially in a taper.
Alternatively, the tail bone maximum dimension D of described tail spindle and being set as of length L: described maximum dimension D 1-2mm larger than the most outside diameter of standard Morse's taper standard.
Alternatively, when the most outside diameter of described Morse's taper is 31.267mm, described tail bone maximum dimension D is set as 32.267-33.267mm.
Alternatively, the threaded set of described tail spindle is at the tail bone maximum gauge of described tail spindle near centre head side, and described screw thread adopts standard regular screw threads, and the diameter of thread equals tail bone maximum diameter D, and reach L is 20-30mm.
Alternatively, the thickness of described flange is 10-15mm, and the internal thread of described flange and the threaded portion of described tail spindle can be worked in coordination, and the external diameter of described flange compares the large 40mm of its internal thread diameter.
Alternatively, offer the opening of 6-8 10mmX10mm in the periphery of flange, can coordinate with a hook-shaped wrench and carry out turn.
Adopt technique scheme, tail spindle can be dismantled from lathe fast.

Detailed description of the invention
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other embodiment can also be obtained according to the embodiment of these accompanying drawings.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment
Shown in composition graphs 1 and Fig. 2, for the tail spindle structure of one embodiment of the invention, tail spindle 1 comprises connected tail bone 102 and centre head 101, screw thread 103 part is comprised between the tail bone 102 of tail spindle 1 and centre head 101, wherein, tail spindle 1 also comprises a flange 2 coordinated with the screw thread 103 of tail spindle.The tail bone 102 of tail spindle is substantially in a taper, and the maximum dimension D of tail bone 102 of tail spindle and being set as of length L: maximum dimension D 1-2mm larger than the most outside diameter of standard Morse's taper standard, when the most outside diameter of Morse's taper is 31.267mm, described tail bone maximum dimension D is set as 32.267-33.267mm; The screw thread 103 of tail spindle is set in tail bone 102 maximum gauge of tail spindle near centre head 101 side, and this screw thread adopts standard regular screw threads, and the diameter of thread equals tail bone maximum diameter D, and reach L is 20-30mm; The thickness of flange 2 is 10-15mm, and the internal thread of flange 2 and screw thread 103 part of tail spindle can be worked in coordination, and the external diameter of flange 2 compares the large 40mm of its internal thread diameter; As shown in Figure 2, offer the opening 201 of 6-8 10mmX10mm in the periphery of flange 2, can coordinate with a hook-shaped wrench and carry out turn.
Further as shown in Figure 3, when installing tail spindle of the present invention, first dismounting flange 2 being mounted on tail spindle 1, and making the tail cone exposed portion screw thread of tail spindle, at this moment tail spindle 1 is mounted in lathe 3 center hole, can well with center hole location fit.When needing dismounting, turn dismounting flange 2, makes flange 2 face hold out against the end face of lathe 3 center hole, and turn dismounting flange 2, utilizes screw thread to eject top, reach the object of quick-detachment again.
In sum, although the invention discloses above preferred embodiment, above preferred embodiment does not limit the scope of the invention, and without departing from the spirit and scope of the present invention, the variation done all belongs to protection scope of the present invention to those skilled in the art.
