Abstract
The utility model discloses a quick positioning thread chuck, comprising a chuck main body. The chuck main body comprises a connector for connecting the main shaft part of a machine tool and a thread clamping chuck for connecting blank, as well as further comprises a pressure plate which is sheathed on the thread clamping chuck in a sliding manner; the edge of the pressure plate extends out of the connector in radial direction; the main shaft part of the machine tool pushes the edge of the pressure plate so as to support the upper end surface of the pressure plate against the end surface of the clamping end of the blank; by means of the axial pushing force of the pressure plate on the blank, the blank is locked on the thread clamping chuck. The thread chuck has a simple structure, is convenient to operate and has high positioning precision; the blank can be quickly clamped and dismounted, so that the machining efficiency and quality are improved.
Description
Technical field
The utility model belongs to the anchor clamps in the machining, relates in particular to the quick positioning threads chuck that is applied on the lathe.
Background technology
The screw thread chuck as a kind ofly be installed in the machine tool chief axis end, with the strain clamping work pieces of removable claw or clamping element or the machine tool accessories of cutter, be widely used at mechanical processing industry; One end of screw thread chuck is connected with the processing axle of lathe, its other end spins by screw thread and blank, the disassembly process of blank, the operator often will beat or pull blank by instrument, above-mentioned clamping process not only efficient is low, dangerous big, can't guarantee the axiality between blank and the screw thread chuck, cause the blank lumber recovery to descend.Therefore, be necessary traditional screw thread chuck is improved, to overcome above-mentioned shortcoming.
Summary of the invention
Problem to be solved in the utility model just provides simple in structure, easy to operate quick positioning threads chuck, and the positioning accuracy height can be realized quick-clamping, the dismounting of blank, to improve working (machining) efficiency and crudy.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: quick positioning threads chuck, comprise the chuck body, described chuck body comprises the connector that connection lathe main shaft part is used and connects the screw thread clamping head that blank is used, it is characterized in that: comprise that also slip cap is contained in the platen on the screw thread clamping head, described platen edge extends radially out connector, machine tool chief axis portion promotes the platen edge makes the platen upper surface prop up blank clamping end end face, by the axial thrust of platen blank clamping end is locked on the screw thread clamping head.
The beneficial effects of the utility model:
1, the quick positioning threads chuck that provides described in the utility model has only been set up platen on original chuck, and is simple in structure, design cost is low;
2, blank only needs to be screwed into several teeth slightly on screw thread clamping head and gets final product when connecting thread clamping head, has saved the blank clamping time greatly, increases work efficiency;
3, because blank only is screwed into several teeth on screw thread clamping head when clamping, thus when dismantling, blank is easy to just can take off, and unlike traditional screw thread chuck, need beat or pull with strength blank and could dismantle, improved safety coefficient;
4, the quick positioning threads chuck that provides described in the utility model is when realizing the blank fast assembling-disassembling, can also improve the clamping precision of blank: platen has corrective action to the axial thrust of blank to the axial line of blank, make it keep higher axiality with the screw thread chuck, thereby the less blank of energy allowance, improve the blank lumber recovery.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is this practical use principle figure.
The specific embodiment
With reference to Fig. 1, quick positioning threads chuck of the present utility model, comprise the chuck body, this chuck body is made up of a connector 1, screw thread clamping head 2, a platen 4, connector 1 is to be connected in the machine tool chief axis portion 5, screw thread clamping head 2 connects blank 3, and platen 4 slip caps are contained on the screw thread clamping head 2, and platen 4 edges extend radially out connector 1.
Concrete operating process is as follows: determine the thickness of platen 4, as shown in fig. 1 as can be known: platen 4 thickness B=D-A-C; The length of D screw thread clamping head 2 wherein; A is the length that blank clamping end 31 is screwed into screw thread clamping head 2; C is the spacing between platen 4 upper surfaces and blank 3 clamping end end faces under the free state.Determined after the thickness of platen 4, with the blank clamping end 31 screw thread clamping head 2 of screwing on, connector 1 with the chuck body is installed in the machine tool chief axis portion 5 again, the handle of operation lathe is retracted in the machine tool chief axis portion 5 the chuck body backward, machine tool chief axis portion 5 promotes platen 4 edges moves forward until the clamping end that props up blank 3 platen 4 upper surfaces, the lock collet body is finished clamping process then, and blank 3 at this moment is locked on the screw thread clamping head 2 by the axial thrust of platen 4 to its clamping end.After blank 3 machined, the chuck body stretched out machine tool chief axis portion 5, and platen 4 unclamps, and did not have other external force effects between blank 3 and the screw thread clamping head 2, very easily just can take off blank 3, finished discharge process.
Claims (1)
1. quick positioning threads chuck, comprise the chuck body, described chuck body comprises connector (1) that connects lathe main shaft part (5) usefulness and the screw thread clamping head (2) that connects blank (3) usefulness, it is characterized in that: comprise that also slip cap is contained in the platen (4) on the screw thread clamping head (2), described platen (4) edge extends radially out connector (1), machine tool chief axis portion (5) promotes platen (4) edge makes platen (4) upper surface prop up blank clamping end (31) end face, by the axial thrust of platen (4) blank clamping end (31) is locked on the screw thread clamping head (2).
