Summary of the invention
For the problems referred to above, the utility model provides a kind of interior top structure welding earphone, its make the interior top of both sides can carry out enlargement and contraction simultaneously and guarantee synchronously to carry out, precision is high, improves the production efficiency of whole product line.
A kind of interior top structure welding earphone, its technical scheme is such: it comprises positioning seat, the cylindrical structure of described positioning seat, it is characterized in that: the Vertical dimension center of described positioning seat is provided with the driving cylinder of Vertical dimension, the lower end of described driving cylinder is connected with inner core, the conical structure of bottom in enlarging from bottom to top of described inner core, the both sides of described inner core are furnished with one to interior top, described interior top straight line is to the line correspondence positioning chamber being arranged in described positioning seat, the inner side of described interior top is close to the outer face of the described conical structure of correspondence position respectively, two described interior tops are respectively arranged with outer back-moving spring on the direction of straight line positioning chamber, fastening and the described positioning seat in one end of described outer back-moving spring, the other end is fastenedly connected the footpath convex backstay of described interior top, described evagination backstay and described straight line positioning chamber are not interfered.
It is further characterized in that: the inner side of described interior top is specially cylinder-shaped bearing structure, the outer face being close to the conical structure of described inner core of the outer ring surface of cylinder-shaped bearing structure, cylinder-shaped bearing structure and conical structure guarantee that the outer face of described conical structure is close in the inner side of interior top, when conical structure rises or declines, guarantee that frictional force is little, can not additional friction be produced;
The outer side center position of described interior top is provided with axial arranged inner spring, the two ends of described inner spring push up respectively fill described interior top inner side axial seat, outside top, make interior top can carry out axis adjustment automatically according to the thickness of pressed convenient barrel, guarantee the reliable and stable of axial compressive force;
The outside being positioned at described top along the direction of straight line positioning chamber is respectively arranged with two outer back-moving springs, the outer back-moving spring of every bar is connected respectively the footpath convex backstay of top in described in one of them, namely the reset come directly towards in every bar outer back-moving spring correspondence control one, guarantees that interior top quick and precisely resets when resetting and puts in place.
After adopting structure of the present utility model, the piston rod of the driving cylinder of Vertical dimension declines and drives inner core to decline, and then drive conical structure to decline, because conical structure is in flaring structure from bottom to top, conical structure drives the interior top of both sides to expand outwardly respectively, and then make the outer end of interior top tightly suppress the correspondence position of the inwall of convenient barrel, after completing the welding of weldering ear, the piston rod of cylinder is driven to rise, shrink under the drive of interior top back-moving spring outside, it makes the interior top of both sides can carry out enlargement and contraction simultaneously, and guarantee synchronously to carry out, precision is high, improve the production efficiency of whole product line.
Accompanying drawing explanation
Fig. 1 is that front view of the present utility model partly cuts open structural representation;
Fig. 2 is upward view structural representation of the present utility model;
Reference name in figure corresponding to each sequence number is as follows:
Positioning seat 1, driving cylinder 2, inner core 3, conical structure 4, interior top 5, straight line positioning chamber 6, outer back-moving spring 7, evagination backstay 8, cylinder-shaped bearing structure 9, inner spring 10, inner side axial seat 11, top, outside 12.
Detailed description of the invention
A kind of interior top structure welding earphone, see Fig. 1, Fig. 2: it comprises positioning seat 1, the cylindrical structure of positioning seat 1, the Vertical dimension center of positioning seat 1 is provided with the driving cylinder 2 of Vertical dimension, the lower end of cylinder 2 is driven to be connected with inner core 3, the conical structure 4 of bottom in enlarging from bottom to top of inner core 3, the both sides of inner core 3 are furnished with one to interior top 5, interior top 5 straight line is to the line correspondence positioning chamber 6 being arranged in positioning seat 1, the inner side of interior top 5 is close to the outer face of the conical structure 4 of correspondence position respectively, come directly towards 5 in two and be respectively arranged with outer back-moving spring 7 on the direction of straight line positioning chamber 6, one end of outer back-moving spring 7 is anchored on positioning seat 1, the other end is fastenedly connected the footpath convex backstay 8 of interior top 5, evagination backstay 8 and straight line positioning chamber 6 are not interfered.
The inner side of interior top 5 is specially cylinder-shaped bearing structure 9, the outer face of the conical structure 4 being close to inner core 3 of the outer ring surface of cylinder-shaped bearing structure 9, cylinder-shaped bearing structure 9 and conical structure 4 guarantee that the outer face of conical structure 4 is close in the inner side of interior top 5, when conical structure 4 rises or declines, guarantee that frictional force is little, can not additional friction be produced;
The outer side center position of interior top 5 is provided with axial arranged inner spring 10, the two ends of inner spring 10 push up inner side axial seat 11, the top, outside 12 of top 5 in dress respectively, make interior top 5 can carry out axis adjustment automatically according to the thickness of pressed convenient barrel, guarantee the reliable and stable of axial compressive force;
