The invention discloses a kind of self-locking clamps, including chuck body, movable clamp and reinforcing lever, the chuck body has fluting, the top of the fluting of chuck body is equipped with retaining clip, the upper end of retaining clip has preceding clamping jaw, movable clamp is set on the front of chuck body, and movable clamp has a rotating junction, the rotating junction of movable clamp is rotationally connected in the fluting of chuck body, the upper end of the activity clamp has the rear clip-claw cooperated with the preceding clamping jaw of chuck body, spring is equipped between retaining clip and movable clamp, the posterior rotation of reinforcing lever is connected to the lower part of the fluting of chuck body, and the end effect of lever is reinforced in movable clamp.The present invention is by reinforcing leverage in movable clamp, so that movable clamp rotates, so that open or close between rear clip-claw and the preceding clamping jaw of retaining clip, to realize that the clamping to PIN needle is locked, it is very easy to use, it is time saving and energy saving without opening fixture by manpower.
Description
Technical field
The present invention relates to a kind of clamping device, in particular to a kind of self-locking clamp.
Background technique
In auto-parts, there is a kind of high voltage ring skeleton product, product ontology is pre- by the way of insertion or embedment
Let the acupuncture needle remain at a certain point shape connector (PIN needle), for welding wiring board.In order to reach the use function of product, PIN needle is inserted into product ontology,
Enough insertion dynamics are needed, guarantee that PIN needle cannot be separated with product ontology.In process of production, test coil is often needed to
Whether the pulling capacity of skeleton PIN needle meets standard, and pulling capacity is sufficiently large, just can guarantee that PIN needle is not easy to separate with product ontology.It is existing
Have in technology, tests the fixture of pulling capacity, it is inconvenient to use, when clamping PIN needle, manpower is needed to open fixture, it is time-consuming and laborious.
Summary of the invention
In order to solve the above technical problems, the purpose of the present invention is to provide a kind of self-locking clamp, easy to use, time saving province
Power.
To realize above-mentioned technical purpose and the technique effect, the invention is realized by the following technical scheme: one kind is certainly
Locking fixture, including chuck body, movable clamp and reinforcing lever, the chuck body have fluting, the fluting of chuck body
Top be equipped with retaining clip, after there is preceding clamping jaw, the activity clamp to be set to chuck body for the upper end of the retaining clip
In portion, and the activity clamp has a rotating junction, and the rotating junction of movable clamp is rotationally connected with opening for chuck body
In slot, the upper end of the activity clamp has the rear clip-claw cooperated with the preceding clamping jaw of chuck body, and the retaining clip and activity are pressed from both sides
Spring is equipped between body, the posterior rotation of the reinforcing lever is connected to the lower part of the fluting of chuck body, and reinforces lever
End effect is in movable clamp.
Further, the rear clip-claw of the preceding clamping jaw of retaining clip and movable clamp all has clamping face, and the folder of preceding clamping jaw
The clamping face for holding face and rear clip-claw is serrated face.
Further, the rear portion of the chuck body is equipped with erecting bed, and the activity clamp is set to the peace of chuck body
It fills on platform.
Further, the rotating junction of movable clamp and the rear portion of reinforcing lever are rotationally connected with by positioning pin
In the fluting of chuck body.
The beneficial effects of the present invention are: being pressed from both sides by reinforcing leverage in activity when using drawing PIN needle of the present invention
Body, so that movable clamp rotation, so that the rear clip-claw of movable clamp upper end is swung, so that the preceding clamping jaw of rear clip-claw and retaining clip
Between open or close, the clamping of PIN needle is locked to realize, it is very easy to use, without passing through manpower opening, time saving province
Power.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the fit structure schematic diagram of the chuck body and movable clamp in the present invention.
Specific embodiment
The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawing, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
As depicted in figs. 1 and 2, a kind of self-locking clamp, including chuck body 1, movable clamp 2 and reinforcing lever 3, it is described
Chuck body 1 has fluting 11, and the top of the fluting 11 of chuck body 1 is equipped with retaining clip 12, the upper end of the retaining clip 12
With preceding clamping jaw 13, the activity clamp 2 is set on the rear portion of chuck body 1, and the activity clamp 2 has a rotation connection
The rotating junction 21 in portion 21, movable clamp 2 is rotationally connected in the fluting 11 of chuck body 1, the upper end tool of the activity clamp 2
There is the rear clip-claw 22 with the cooperation of the preceding clamping jaw 13 of chuck body 1.The rear clip-claw of the preceding clamping jaw 13 of retaining clip 12 and movable clamp 2
22 all have clamping face, and the clamping face of the clamping face of preceding clamping jaw 13 and rear clip-claw 22 is serrated face.The retaining clip 12
Spring 4 is equipped between movable clamp 2, the posterior rotation of the reinforcing lever 3 is connected under the fluting 11 of chuck body 1
Portion, and the end effect of lever 3 is reinforced in movable clamp 2.
Furtherly, the rear portion of the chuck body 1 is equipped with erecting bed 14, and the activity clamp 2 is set to chuck body 1
Erecting bed 14 on.
Furtherly, the rotating junction 21 of movable clamp 2 and the rear portion of reinforcing lever 3 pass through positioning pin 5 and rotate
It is connected in the fluting 11 of chuck body 1.
When using drawing PIN needle of the present invention, lever 3 is reinforced by rotation, acts on movable clamp using lever principle
2, so that movable clamp 2 rotates, so that the rear clip-claw 22 of 2 upper end of movable clamp is swung out, so that rear clip-claw 22 and fixing clamp
It is opened between the preceding clamping jaw 13 of body 12, then makes PIN needle between preceding clamping jaw 13 and rear clip-claw 22, then unclamp reinforcing lever
3, under the action of spring 4, the rear clip-claw 22 of the preceding clamping jaw 13 of retaining clip 12 and movable clamp 2 clamps PIN needle, then utilizes
The fixture drawing PIN needle, is tested with the pulling capacity to PIN needle, and then the grafting tested between PIN needle and product ontology can
By property.Of the invention is very easy to use, time saving and energy saving without being opened by manpower, and compares the clamping of PIN needle locking
Reliably.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure or equivalent flow shift made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant skills
Art field, is included within the scope of the present invention.
