Abstract
The invention discloses a self-locking device which comprises a base, a clamp and a self-locking part. The clamp is arranged on the base and clamps a workpiece with the help of external force, the self-locking part is arranged on the base and comprises a self-locking handle and an arc-shaped supporting and holding portion for supporting and holding the clamp, and a supporting and holding plane is arranged on the supporting and holding portion of the self-locking part. In the self-locking device, when the self-locking part rotates to a certain angle, the contact planes of the supporting and holding plane and the clamp abut against each other, and therefore the workpiece is clamped tightly, and the self-locking device is simple in process, easy to operate and high in reliability.
Description
Technical field
The present invention relates to fixation workpiece technical field in machinery, relate in particular to a kind of self-locking device.
Background technology
In present machine-building, its workpiece firmly extremely important, a skew all can cause workpiece defective.But in prior art, most of robust structure is all to complete and to implement to fix by extraneous application of force apparatus.Like this, use apparatus to complete and greatly increased manufacturing cost.
Summary of the invention
Object of the present invention is exactly that simple to operate, reliability is high, need can not complete by the application of force apparatus device of fixation workpiece in order to provide a kind of technique simple.
In order to solve above proposed problem, the invention provides a kind of self-locking device, comprising:
Pedestal;
Fixture, is arranged on pedestal, by by external force holding workpiece;
Self-locking body, is arranged on pedestal, includes Self-locking handle and for supporting the arc support division of described fixture;
Wherein, the arc support division on described self-locking body is provided with one and supports plane.
As a further improvement on the present invention, described fixture and described self-locking body contact portion are a plane.
As a further improvement on the present invention, described Self-locking handle and the one-body molded setting of described arc support division.
As a further improvement on the present invention, on described arc support division, also comprise a through hole, for being connected to described pedestal.
As a further improvement on the present invention, also comprise a connection piece, run through described through hole, be connected in described pedestal.
As a further improvement on the present invention, described self-locking body rotates centered by described connector.
Accompanying drawing explanation
Fig. 1 is a kind of self-locking device structural representation of the present invention;
Fig. 2 is self-locking body structural representation in a kind of self-locking device of the present invention;
The specific embodiment
Describe the present invention below with reference to the specific embodiment shown in the drawings.But these embodiments do not limit the present invention, the conversion in structure, method or function that those of ordinary skill in the art makes according to these embodiments is all included in protection scope of the present invention.
Shown in please refer to the drawing 1 and Fig. 2, the invention provides a kind of self-locking device, comprising: pedestal 10, provides an operating platform; Fixture 20, is arranged on pedestal 10, by by external force holding workpiece, concrete, and fixture one side supports workpiece, and opposite side needs external force device to support relatively, thereby reaches the object of holding workpiece; Self-locking body 30, is arranged on pedestal 10, includes Self-locking handle 31 and for supporting the arc support division 32 of described fixture, and its Self-locking handle 31 and the one-body molded setting of arc support division 32 lay respectively at the two ends of this self-locking body 30.
Wherein, the contact portion of fixture and self-locking body 30 is a plane 21, and its self-locking body arch section joint jig plane 21 parts form a rotary device.On the arc support division 32 of self-locking body 30, comprise a through hole 321, this through hole 321 is by the connector 323 in the present invention, through its through hole 321, be connected on pedestal 10, preferably, this connector 323 is less than the diameter of through hole 321 through the section diameter of through hole 321, self-locking body 30 just can rotate take connector 323 as axle like this.
In the present invention, the arc support division 32 of self-locking body 30 is provided with one and supports plane 33, in the time that self-locking body 30 turns to certain angle, supports plane 33 identical with the plane 21 on fixture 20, thereby has formed the device of clamping work pieces.In this device, Self-locking handle 31 is set as circular arc, has greatly reduced the resistance in rotation process, and in operative employee's operating process, simple to operate, reliability is high.
Be to be understood that, although this description is described according to embodiment, but be not that each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should make description as a whole, technical scheme in each embodiment also can, through appropriately combined, form other embodiments that it will be appreciated by those skilled in the art that.
Listed a series of detailed description is above only illustrating for feasibility embodiment of the present invention; they are not in order to limit the scope of the invention, all do not depart from the equivalent embodiment that skill spirit of the present invention does or change and all should be included in protection scope of the present invention within.
