Abstract
The invention discloses a kind of self-locking clamp, including chuck body, activity clamp and afterburning lever, described chuck body has fluting, the top of the fluting of chuck body is provided with retaining clip, the upper end of retaining clip has front jaw, activity clamp is arranged on the front portion of chuck body, and activity clamp has a rotating junction, the rotating junction of activity clamp is rotationally connected with in the fluting of chuck body, the upper end of this activity clamp has the rear clip-claw that the front jaw with chuck body coordinates, it is provided with spring between retaining clip and activity clamp, the posterior rotation of afterburning lever is connected to the bottom of the fluting of chuck body, and the end effect of reinforcing lever is in activity clamp.The present invention passes through afterburning leverage in activity clamp so that activity clamp rotates so that opens between rear clip-claw and the front jaw of retaining clip or closes, thus realize the locking of the clamping to PIN needle, very easy to use, it is not necessary to open fixture by staff, time saving and energy saving.
Description
Technical field
The present invention relates to a kind of clamping device, particularly to a kind of self-locking clamp.
Background technology
In auto-parts, having a kind of high voltage ring skeleton product, its product ontology uses the mode inserted or imbed pre-
Let the acupuncture needle remain at a certain point shape connector (PIN needle), is used for welding wiring board.In order to reach the use function of product, PIN needle inserts product ontology,
Need enough insertion dynamics, it is ensured that PIN needle can not separate with product ontology.In process of production, often need to test coil
Whether the pulling capacity of skeleton PIN needle meets standard, and pulling capacity is sufficiently large, and guarantee PIN needle is difficult to separate with product ontology.Existing
Have in technology, the fixture of test pulling capacity, in-convenience in use, when clamping PIN needle, need staff to open fixture, waste time and energy.
Content of the invention
For solving above-mentioned technical problem, it is an object of the invention to provide a kind of self-locking clamp, easy to use, save time province
Power.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, the present invention is achieved through the following technical solutions: one is certainly
Locking fixture, including chuck body, activity clamp and afterburning lever, described chuck body has fluting, the fluting of chuck body
Top be provided with retaining clip, the upper end of this retaining clip has a front jaw, after described activity clamp is arranged at chuck body
In portion, and this activity clamp has a rotating junction, and the rotating junction of activity clamp is rotationally connected with opening of chuck body
In groove, the upper end of this activity clamp has the rear clip-claw that the front jaw with chuck body coordinates, described retaining clip and activity folder
Being provided with spring between body, the posterior rotation of described afterburning lever is connected to the bottom of the fluting of chuck body, and afterburning lever
End effect is in activity clamp.
Further, the rear clip-claw of the front jaw of retaining clip and activity clamp is respectively provided with clamping face, and the folder of front jaw
Hold face and the clamping face of rear clip-claw is serrated face.
Further, the rear portion of described chuck body is provided with erecting bed, and described activity clamp is arranged at the peace of chuck body
On dress platform.
Further, the rotating junction of activity clamp and the rear portion of afterburning lever are all rotationally connected with by alignment pin
In the fluting of chuck body.
The invention has the beneficial effects as follows: when utilizing drawing PIN needle of the present invention, pressed from both sides in activity by afterburning leverage
Body so that activity clamp rotates, thus the rear clip-claw of activity clamp upper end swings so that the front jaw of rear clip-claw and retaining clip
Between open or close, thus realize that very easy to use, it is not necessary to be opened by staff, save time province to the clamping of PIN needle locking
Power.
Brief description
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the chuck body in the present invention and the fit structure schematic diagram of activity clamp.
Detailed description of the invention
Below in conjunction with the accompanying drawings presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made and apparent clearly defines.
As depicted in figs. 1 and 2, a kind of self-locking clamp, including chuck body the 1st, activity clamp 2 and afterburning lever 3, described
Chuck body 1 has fluting 11, and the top of the fluting 11 of chuck body 1 is provided with retaining clip 12, the upper end of this retaining clip 12
Having front jaw 13, described activity clamp 2 is arranged on the rear portion of chuck body 1, and this activity clamp 2 has a rotation and connects
Portion 21, the rotating junction 21 of activity clamp 2 is rotationally connected with in the fluting 11 of chuck body 1, the upper end tool of this activity clamp 2
There is the rear clip-claw 22 that the front jaw 13 with chuck body 1 coordinates.The front jaw 13 of retaining clip 12 and the rear clip-claw of activity clamp 2
22 are respectively provided with clamping face, and the clamping face of front jaw 13 and the clamping face of rear clip-claw 22 are serrated face.Described retaining clip 12
And being provided with spring 4 between activity clamp 2, the posterior rotation of described afterburning lever 3 is connected under the fluting 11 of chuck body 1
Portion, and the end effect of afterburning lever 3 is in activity clamp 2.
Furtherly, the rear portion of described chuck body 1 is provided with erecting bed 14, and described activity clamp 2 is arranged at chuck body 1
Erecting bed 14 on.
Furtherly, the rotating junction 21 of activity clamp 2 and the rear portion of afterburning lever 3 are all rotated by alignment pin 5
It is connected in the fluting 11 of chuck body 1.
When utilizing drawing PIN needle of the present invention, by rotating afterburning lever 3, bar rod principle is utilized to act on activity clamp
2 so that activity clamp 2 rotates, thus the rear clip-claw 22 of activity clamp 2 upper end swings out so that rear clip-claw 22 and geometrical clamp
Open between the front jaw 13 of body 12, then make PIN needle be positioned between front jaw 13 and rear clip-claw 22, then unclamp afterburning lever
3, under the effect of spring 4, the front jaw 13 of retaining clip 12 and the rear clip-claw 22 of activity clamp 2 clamp PIN needle, then utilize
This fixture drawing PIN needle, tests with the pulling capacity to PIN needle, and then the grafting between test PIN needle and product ontology can
By property.The present invention's is very easy to use, it is not necessary to opened by staff, time saving and energy saving, and the clamping locking to PIN pin is compared
Reliably.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention, every utilize this
Equivalent structure or equivalence flow process that bright specification and accompanying drawing content are made convert, or are directly or indirectly used in other related skills
Art field, all in like manner includes in the scope of patent protection of the present invention.
