It is low, and leather sheath 1 is easy to cause to deform, plastic tube 2 is not easy to be laid flat, leads to the not of uniform size of earphone leather sheath 1, influence product
Quality.
Utility model content
In view of the deficienciess of the prior art, the purpose of the utility model is to provide a kind of for the true of earphone leather sheath assembling
Empty adsorption jig, to solve the above problems.
To achieve the goals above, the technical scheme adopted by the utility model is
A kind of vacuum suction jig for the assembling of earphone leather sheath, including jig bottom plate, positioning ring and vacuum pump, it is described to control
The surface for having bottom plate has a positioning groove, and the bottom surface of the locating slot is additionally provided with symmetrically arranged first and vacuumizes slot and second very
Empty slot, jig bottom plate is interior to have symmetrically arranged first gas circuit and the second gas circuit, and first gas circuit vacuumizes slot company with first
Logical, second gas circuit vacuumizes slot with second and is connected to, and first gas circuit and the second gas circuit are also true by hose and institute respectively
Sky pump connection；The positioning ring is installed in the locating slot and transition fit therewith, and positioning ring is vertically arranged with several
Positioning ring upper space is vacuumized slot with described first respectively, second vacuumizes slot and be connected to by venthole, the venthole.
In further technical solution, the top of the positioning ring is equipped with a positioning region, and the outer diameter of positioning region is less than described
Positioning ring.
In further technical solution, the inner wall of the positioning ring is equipped with a positive stop lug boss.
In further technical solution, the jig bottom plate and positioning ring are all made of metal material and are made, and surface carries out
Anodized.
It further include manual switch, the manual switch is electrically connected with the vacuum pump in further technical solution.
After adopting the above structure, the utility model is compared to the prior art advantageously: the utility model passes through
Vacuum tool fixes leather sheath, and the flap of leather sheath is adsorbed, to guarantee that the sponge in earphone leather sheath exposes simultaneously
And horizontality is kept, plastic tube is directly installed to the installation effectiveness that plastic tube is improved to the top of sponge convenient for worker, and
And can guarantee that plastic tube can be horizontally mounted, the quality of product improves.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
A view is the structural schematic diagram before plastic tube assembling in Fig. 1, and b view is the structural schematic diagram after plastic tube assembling；
Fig. 2 is the overall structure diagram of the utility model；
Fig. 3 is the structural schematic diagram of the jig bottom plate of the utility model；
Fig. 4 is the structural schematic diagram of the positioning ring of the utility model.
Specific embodiment
Below it is only the preferred embodiment of the utility model, does not therefore limit the protection scope of the utility model.
A kind of vacuum suction jig for the assembling of earphone leather sheath as shown in Figures 1 to 4, including jig bottom plate 3, positioning
The surface of ring 4, vacuum pump and manual switch, the jig bottom plate 3 has a positioning groove 31, and the bottom surface of the locating slot 31 is also set
There is symmetrically arranged first to vacuumize slot 31a and the second vacuum tank, there is symmetrically arranged first gas circuit 31c in jig bottom plate 3
With the second gas circuit 31d, the first gas circuit 31c vacuumizes slot 31a with first and is connected to, and the second gas circuit 31d and second takes out true
Empty slot 31b connection, the first gas circuit 31c and the second gas circuit 31d are also connected to by hose with institute vacuum pump respectively, described manual
Switch is electrically connected with the vacuum pump；The positioning ring 4 is installed in the locating slot 31 and transition fit therewith, positioning ring 4
With several ventholes 41 being vertically arranged, the venthole 41 vacuumizes 4 upper space of positioning ring with described first respectively
Slot, second vacuumize slot connection.
When work, leather sheath 1 is tucked into first in the hole of positioning ring 4, leather sheath 1 is tentatively fixed, then by leather sheath 1
Flap 12 turns down, and entangles the outer wall section of positioning ring 4, so that the sponge being located in leather sheath exposes；After leather sheath fixation finishes,
Positioning ring 4 is installed in the locating slot 31 of jig bottom plate 3, the bottom face contact of its underpart and locating slot 31, so that positioning ring 4
Venthole 41 slot 31a and second vacuumized with first respectively vacuumize slot 31b and be connected to, press manual switch, open vacuum pump
Later, slot 31a and second is vacuumized by first vacuumizing slot 31b and all take the air in venthole 41 away, leather sheath 1 is inhaled
It is attached on positioning ring 4；Plastic tube 2 is directly horizontally arranged the top of sponge 11 by last worker, then turns down flap 12
Original position is gone back to, plastic tube 2 is fixed；Leather sheath 1 is fixed by vacuum tool, not only increases the installation effectiveness of plastic tube 2,
And can guarantee that plastic tube 2 can be horizontally mounted, the quality of product improves.
In the present embodiment, the top of the positioning ring 4 is equipped with a positioning region 42, and it is described fixed that the outer diameter of positioning region 42 is less than
Position ring 4；After the flap 12 of leather sheath is turned down, flap 12 just be located in positioning region 42, be more conducive to determining for leather sheath 1
Position, further increases the installation effectiveness of plastic tube 2.
In the present embodiment, the inner wall of the positioning ring 4 is equipped with a positive stop lug boss 43；Pass through the inner wall in positioning ring 4
A positive stop lug boss 43 is added, when earphone leather sheath is filled in positioning ring 4, can be sunk to avoid leather sheath transition, to ensure that earphone
The sponge of leather sheath is always positioned at the top of positioning ring 4, convenient for the installation of plastic tube 2.
In the present embodiment, the jig bottom plate 3 and positioning ring 4 are all made of metal material and are made, and surface has carried out sun
Pole oxidation processes；Since earphone leather sheath is before installing plastic tube, it also will use decontaminated water and carry out surface cleaning, so earphone skin
The surface of set can remain decontaminated water, easily corrode jig, therefore after anodized is done on jig surface, can be improved and control
The service life of tool.
The above content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
With novel thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as
