Abstract
The utility model discloses a chuck positioning device, which comprises a chuck, machine workbench centering holes and a centering mandrel, and the centering mandrel is coaxially connected with the centering holes. The chuck positioning device solves the technical problems of low centering accuracy and difficulty in operation for the chuck of a machine. With the adoption of the chuck positioning device disclosed by the utility model, a positioning reference substance is provided for the chuck by the centering mandrel matched with the centering holes, so that the centering accuracy is effectively improved, the difficulty in operation is lowered, and the efficiency for operational machining of the machine is increased.
Description
Technical field
The utility model relates to field of machining, particularly a kind of chuck positioner.
Background technology
Utilizing chuck to clamp is the machining most common means, kinds such as scroll chuck, chuck is generally arranged.Common ground when these chucks use is the requirement to part shape, and for example scroll chuck is suitable for processing the cross section and is circular or hexagonal part, and chuck is fit to the part that the processing cross section is circular, square, rectangle or ellipse.
In the machining work of reality, chuck is an extremely important machine tool accessories or instrument, is used to realize accurate location and chucking with workpiece usually.Except that lathe; In the manual operation and mechanically actuated of routine, the problem that the use of chuck has to face is must earlier chuck accurately be located before the chucking; Otherwise just can produce departing from of workpiece; Cause processing work to be scrapped, increase the scrappage that part is produced, increase production cost.
Summary of the invention
For addressing the above problem, the utility model discloses the chuck positioner, through location mandril, reduced the difficulty of chuck location effectively, improved the efficient of chuck location.
The disclosed chuck positioner of the utility model comprises chuck, platen internal point, centering plug, and the centering plug is connected with the platen internal point is coaxial.The disclosed chuck positioner of the utility model is realized quick on platen, the accurate location of chuck through the location mandril that is provided with; Improved the machining accuracy of work piece; Guarantee product quality, reduce the working time that chuck is located on platen, improved efficiency; Simple in structure, the low cost of manufacture of this improved location mandril, and the reusable production cost of having practiced thrift effectively simultaneously.
A kind of improvement of the disclosed chuck positioner of the utility model, workbench is provided with pressing plate, and pressing plate is arranged on the periphery of workbench internal point.This improvement is provided with pressing plate through workbench, has improved the location efficiency of chuck and the stability of chuck location effectively.
A kind of improvement of the disclosed chuck positioner of the utility model, pressing plate is connected with trapezoid block on being arranged on workbench through stud.This improvement flexibly connects pressing plate and workbench through stud, makes pressing plate to be made pressing plate to adapt to the fixedly requirement of different chucks through spinfunction simultaneously by flexible replacing.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment, further illustrate the utility model, should understand the following specific embodiment only be used to the utility model is described and be not used in the restriction the utility model scope.
To shown in Figure 3, the disclosed chuck positioner of the utility model comprises chuck 2, platen internal point 3 and centering plug 1, centering plug 1 and 3 coaxial connections of platen internal point like Fig. 1.
A kind of improvement of the disclosed chuck positioner of the utility model, workbench is provided with pressing plate 5, and pressing plate 5 is arranged on the periphery of internal point 3 on the platen.
A kind of improvement of the disclosed chuck positioner of the utility model, pressing plate 5 is connected with trapezoid block on being arranged on workbench 4 through stud.
As shown in Figures 2 and 3,, prepare a centering plug 1, pull down the protection screw on the platen internal point 3, expose platen internal point 3 according to platen internal point 3.After chuck placed workbench substantial middle position, unclamp three-jaw, the plug 1 of will feeling relieved is through inserting in the platen internal point 3 in the middle of the chuck three-jaw.Clamp centering plug 1 through tightening up three-jaw again, confirm that promptly chuck has been implemented on the platen accurately location.Utilize pressing plate 5 that chuck 2 is fixing with workbench 4 again.Pressing plate is movably connected in through stud on the trapezoidal contiguous block of workbench 4, unclamps three-jaw behind the location after accomplishing, and takes out centering plug 1, reinstalls the protection screw on the platen internal point 3.
The disclosed chuck positioner of the utility model is realized quick on platen, the accurate location of chuck through the location mandril that is provided with; Improved the machining accuracy of work piece; Guarantee product quality, reduce the working time that chuck is located on platen, improved efficiency; Simple in structure, the low cost of manufacture of this improved location mandril, and the reusable production cost of having practiced thrift effectively simultaneously.
