Abstract
The invention discloses a centrifugal fixture. The centrifugal fixture comprises a fixture body provided with a cavity, and two or more clamping jaws arranged on the fixture body; the clamping jaws are hinged to the fixture body, one ends extend into the cavity, and the other ends extend to the end part of the fixture body; a positioning disc is arranged at the end part of the fixture body; and a stop pin for limiting a workpiece is arranged on the positioning disc. The centrifugal fixture rotates along with a main shaft of a machine tool to generate centrifugal force; the clamping jaws swing around shaft pins to automatically clamp the workpiece; and the centrifugal fixture is simple in structure, convenient for operation and reliable in clamping, saves both time and labors in workpiece unloading, is low in labor intensity of operators, and is high in production efficiency.
Description
Technical field
The invention belongs to comprise use centrifugal force technical field, be specifically related to a kind of centrifugal clamp.
Background technology
It is processed when cover board hole or part axial workpiece the surface quality and positional precision etc. of its both ends of the surface is less demanding at lathe, adopt end-driver center clamping the pusher dog impression that inevitably to stay on workpiece a end face, it is typically permission, adopt scroll chuck accommodate part exist dismounting part cost time, effort, operator's labor intensity is high, and production efficiency is low, and the correction accuracy of end face and endoporus is poor, time is long, and clamping efficiency is low.
Summary of the invention
In view of this, it is an object of the invention to provide a kind of centrifugal clamp, this centrifugal clamp produces centrifugal force by rotating with machine tool chief axis, claw swings and Automatic-clamping workpiece around pivot pin, and simple in construction is easy to operate, reliable clamping, dismounting workpiece is time saving and energy saving, and operator's labor intensity is low, and production efficiency is high.
In order to achieve the above object, one centrifugal clamp of the present invention, including the clamp body being provided with cavity and the claw being arranged on clamp body no less than 2, described claw is hinged on clamp body and its one end is stretched in cavity, the other end extends to clamp body end, described clamp body end is provided with location dish, and described location dish is provided with the backing pin for workpiece.
Further, the end, one end that described claw stretches in cavity is set to ball structure.
Further, described ball structure is set to hollow.
Further, it is provided with liquid in described hollow ball structure.
Further, it is provided with water or grease in described hollow ball structure.
Further, described workpiece setting is speaker upper cover plate, and described location dish is provided with the cannelure for holding upper cover plate projection.
Further, it is provided with, in described clamp body cavity, the Morse taper shank being connected with lathe spindle taper hole.
The beneficial effects of the present invention is:
Centrifugal clamp of the present invention produces centrifugal force by rotating with machine tool chief axis, and claw swings and Automatic-clamping workpiece around pivot pin, and simple in construction is easy to operate, reliable clamping, and dismounting workpiece is time saving and energy saving, and operator's labor intensity is low, and production efficiency is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of centrifugal clamp of the present invention.
Accompanying drawing labelling: 1-claw；2-location dish；3-backing pin；4-pivot pin；5-clamp body；6-Morse taper shank.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
It is illustrated in figure 1 the structural representation of centrifugal clamp of the present invention；One centrifugal clamp of the present invention, including the clamp body 5 being provided with cavity and the claw 1 being arranged on clamp body 5 no less than 2, described claw 1 is hinged on clamp body 5 and its one end is stretched in cavity, the other end extends to clamp body 5 end, described clamp body 5 end is provided with location dish 2, and described location dish 2 is provided with the backing pin 3 for workpiece.
Workpiece is positioned by the present embodiment by location dish 2 end face and backing pin 3, workpiece is carried out pretension by claw 1, after driving, claw 1 rotates with machine tool chief axis and produces centrifugal force, claw 1 swings and Automatic-clamping workpiece around pivot pin 4, this simple in construction, easy to operate, reliable clamping, dismounting workpiece is time saving and energy saving, and operator's labor intensity is low, and production efficiency is high further, the end, one end that preferred described claw 1 stretches in cavity is set to ball structure, and this structure is conducive to claw 1 to rotate generation centrifugal force with machine tool chief axis.
Further, preferred described ball structure is set to hollow, it is provided with liquid in preferred described hollow ball structure, it is provided with water or grease in preferred described hollow ball structure, the present embodiment by arranging water or grease in the spheroid of hollow, advantageously ensure that the balance of claw 1, it is ensured that reliable clamping, improve machining accuracy.
Further, preferred described workpiece setting is speaker upper cover plate, being provided with the cannelure for holding upper cover plate projection on the dish of described location, this structure is easy to the speaker upper cover plate cylindrical with end face and four small boss compositions location on the end face of location dish 2, cannelure and backing pin 3.
Further, it is preferred that being provided with, in described clamp body 5 cavity, the Morse taper shank 6 being connected with lathe spindle taper hole, this structure is for being arranged on lathe by centrifugal clamp, it is simple to dismounting.
What finally illustrate is, preferred embodiment above is only in order to illustrate technical scheme and unrestricted, although the present invention being described in detail by above preferred embodiment, but skilled artisan would appreciate that, in the form and details it can be made various change, without departing from claims of the present invention limited range.
