One end of pole is fixedly connected with the downside of the bottom of two grooves, and the other end of the second connecting rod, the other end of the pole is fixed
On the upside of the one end for connecting the 3rd connecting rod, the other end activity of the 3rd connecting rod runs through the bottom of the 3rd groove, and the 3rd
The other end of connecting rod is fixedly connected with the second crushing block.
It is preferred that, the second spring at least two, and equidistantly distribute the flat side in the first crushing block.
It is preferred that, first crushing block is a quarter cylindrical structure.
It is preferred that, second crushing block is semiglobe.
It is preferred that, one end that the pressure ram is located at cartridge exterior is semiglobe.
Compared with prior art, the beneficial effects of the invention are as follows:The present invention it is simple in construction, by add head rod,
The structures such as sleeve, the first spring, pressure ram and permanent magnet, when needing to open fixture, by connecting external power source, energization electromagnetism
Iron, due to being provided with permanent magnet in pressure ram, makes electromagnet attract pressure ram, pressure ram is pressed down against the second crushing block, make the
Three connecting rods are moved away from pressure ram, and by the effect of pole, in the presence of the 3rd spring, head rod is moved up,
Move up sleeve, now pressure ram keeps the position of the second crushing block of extruding, now again powers off electromagnet, so as to will squeeze
Depression bar is ejected from the first groove, so as to open fixture, this not only firmly secures the position of small-sized copper product, and
Fixture is opened when conveniently needs.

Embodiment
To further appreciate that present disclosure, the present invention is described in detail in conjunction with the accompanying drawings and embodiments.It should be understood that
, embodiment be only the present invention is explained and and it is non-limiting.
A kind of small-sized copper product positioning fixture, including chuck body 1, chuck body 1 are hollow structure, chuck body 1
Provided with matrix clip slot, provided with the head rod 2 being vertically arranged in chuck body 1, fixture sheet is run through in the upper end of head rod 2
The upper end side wall of matrix clip slot is run through in the upper end of body 1, the lower end of head rod 2, and head rod 2 is located in chuck body 1
One section be fixedly connected with connecting plate 7, the upper surface of connecting plate 7 is fixedly connected with the lower end of the 3rd spring 15, the 3rd spring 15
Upper end is fixedly connected on roof on the inner chamber of chuck body 1, and the lower end of head rod 2 is fixedly connected with the upper end of sleeve 3, sleeve
3 inwall is connected with pressure ram 5 by the first spring 4, and the activity of pressure ram 5 is plugged on the inside of sleeve 3, and pressure ram 5 is located at set
One end outside cylinder 3 is semiglobe, and the inside of pressure ram 5 is provided with permanent magnet 6;
The bottom side of the wall of chuck body 1 offers the first groove, and the bottom of the first groove is fixedly connected with electromagnet 14, the
The sidewall symmetry of one groove offers the second groove, and the sidewall symmetry of the first groove offers the 3rd groove, the second groove and
Three grooves are in same plane, and the second groove is located at the top of the 3rd groove, and the bottom of the second groove is fixedly connected with second
One end of spring 9, the other end of second spring 9 is fixedly connected with the flat side of the first crushing block 8, second spring 9 at least two,
And the flat side of the first crushing block 8 is equally distributed on, the flat side of the first crushing block 8 is fixedly connected with the one of the second connecting rod 10
End, the first crushing block 8 is a quarter cylindrical structure, and the other end activity of the second connecting rod 10 runs through the bottom of the second groove
One end of pole 11 is fixedly connected with the downside of end, and the other end of the second connecting rod 10, the other end of pole 11 is fixedly connected with the 3rd
On the upside of one end of connecting rod 12, the other end activity of the 3rd connecting rod 12 runs through the bottom of the 3rd groove, and the 3rd connecting rod 12
The other end be fixedly connected with the second crushing block 13, the second crushing block 13 is semiglobe.
Operation principle:The small-sized copper product for needing to position is put in matrix clip slot bottom, Manual press head rod 2,
Make sleeve 3 by the through hole set by matrix clip slot upper end side wall, sleeve 3 is entered the first groove, sleeve 3 extrudes the first crushing block
8, the region that sleeve 3 and pressure ram 5 enter between the first crushing block 8 and the second crushing block 13, now the first crushing block 8 be stuck in set
The upper end of cylinder 3, extrudes the side wall of head rod 2, so that the position of small-sized copper product is secured, when needing to open fixture,
By connecting external power source, energization electromagnet 14, due to being provided with permanent magnet 6 in pressure ram 5, makes electromagnet 14 attract pressure ram 5,
Pressure ram 5 is pressed down against the second crushing block 13, the 3rd connecting rod 12 is moved away from pressure ram 5, by the effect of pole 11,
Move connecting rod 10, so that the first crushing block 8 is moved away from pressure ram 5, the first crushing block 8 is no longer stuck in head rod
2 side wall, in the presence of the 3rd spring 15, head rod 2 is moved up, and moves up sleeve 3, now pressure ram 5
The position of the second crushing block 13 of extruding is kept, is now again powered off electromagnet 14, so that pressure ram 5 be hit by a bullet from the first groove
Go out, so as to open fixture, this not only firmly secures the position of small-sized copper product, and is opened when being also convenient for needing
Fixture.
