Abstract
The utility model relates to a line card threading device, which belongs to the technical field of production auxiliary tools of motors, and comprises an outer sleeve and a core rod, wherein the outer sleeve is of a hollow structure, and the front end of the outer sleeve is formed with a diameter shrinkage portion whose outer diameter is smaller than an outer sleeve body. The core rod comprises a columnar body and a taper segment, wherein the outer diameter of the columnar body is matched with the inner diameter of the hollow structure of the outer sleeve, the diameter of the front end of the taper segment is smaller, the outer diameter which is close to the columnar body is bigger, the maximum outer diameter of the taper segment is bigger than the outer diameter of the columnar body, and the outer diameter of the diameter shrinkage portion of the outer sleeve is smaller and equal to the maximum outer diameter of the taper segment. The line card threading device is convenient to assemble a wire and a line card, can increase the production efficiency, and solves the problems in the prior art that the wire must be intruded into a via hole of the line card, and the assembly is not very convenient and the like.
Description
Technical field
The utility model relates to a kind of ply-yarn drill threader, belongs to the technical field that motor is produced auxiliary mould.
Technical background
In the process that motor is produced, cause from motor internal that the standing hollow ply-yarn drill of putting is scratched with the foreskin of avoiding outside such as lead between lead such as the power line of motor outside and holding wire and the through wires hole.Generally, the many total external diameters of the through hole of ply-yarn drill less than lead, i.e. the through hole close-fitting of lead and ply-yarn drill, during assembling, lead must be squeezed in the through hole of ply-yarn drill, and assembling is comparatively inconvenient.
Summary of the invention
The utility model purpose is to provide a kind of be convenient to lead and ply-yarn drill assembling, the ply-yarn drill threader that can enhance productivity, and the lead that has solved the prior art existence must be squeezed in the through hole of ply-yarn drill, assembles problems such as comparatively inconvenience.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: it comprises overcoat and plug, described overcoat is hollow structure, the overcoat front end is formed with the reducing diameter part of external diameter less than the overcoat body, plug comprises cylindrical body and conical section, the external diameter of cylindrical body cooperates with the internal diameter of the hollow structure of overcoat, the conical section point diameter is less and bigger near the external diameter at cylindrical body position, the maximum outside diameter of conical section is greater than the external diameter of cylindrical body, and the external diameter of overcoat reducing diameter part is smaller or equal to the maximum outside diameter of conical section.During assembling, plug is inserted into the conical section that makes plug in the overcoat to be exposed to outside the necking part of overcoat, the conical section of plug being inserted in the through hole of ply-yarn drill enlarges the through hole of ply-yarn drill, reducing diameter part with overcoat is inserted in the ply-yarn drill through hole of being opened by expansion again, again plug is pulled out, then lead is passed the hollow structure that always passes the overcoat reducing diameter part from the rear end of overcoat hollow structure, then the reducing diameter part of overcoat being extracted from the through hole of ply-yarn drill both to have made lead be positioned at the endoporus of ply-yarn drill, treat that ply-yarn drill shrinks and lead can be blocked under self flexible effect, thereby make things convenient for the assembling of lead and ply-yarn drill, improved production efficiency.
As preferably, the big cylindrical portion transition that equates with the maximum gauge of conical section by a diameter between the conical section of described plug and the cylindrical body.Wherein, between conical section and cylindrical body, can be beneficial to the through hole expansion of plug with ply-yarn drill by big cylindrical portion transition.
As preferably, the reducing diameter part of described overcoat front end is the thin wall shape structure.
Therefore, the utlity model has and be convenient to the assembling of lead and ply-yarn drill, characteristics such as can enhance productivity.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is a kind of structural representation of the utility model overcoat;
Fig. 3 is the A place partial enlarged drawing of Fig. 1;
Fig. 4 is a kind of structural representation of the utility model plug.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as shown in figures 1 and 3, comprise overcoat 1 and plug 2, overcoat 1 is hollow structure, and as shown in Figure 2, the front end of overcoat 1 is formed with the reducing diameter part 3 of external diameter less than the overcoat body, and reducing diameter part 3 is the thin wall shape structure.As shown in Figure 4, plug 2 comprises cylindrical body 4 and conical section 5, the external diameter of cylindrical body 4 cooperates with the internal diameter of the hollow structure of overcoat 1, conical section 5 point diameters are less and bigger near the external diameter at cylindrical body 4 positions, the maximum outside diameter of conical section 5 is greater than the external diameter of cylindrical body 4, the external diameter of overcoat reducing diameter part 3 is smaller or equal to the maximum outside diameter of conical section, big cylindrical portion 6 transition that equate with the maximum gauge of conical section by a diameter between conical section 5 and the cylindrical body 4.
As shown in figures 1 and 3, during assembling, plug 2 is inserted into the conical section 5 that makes plug 2 in the overcoat 1 to be exposed to outside the necking part 3 of overcoat 1, the conical section 5 of plug 2 being inserted in the through hole of ply-yarn drill 7 enlarges the through hole of ply-yarn drill 7, reducing diameter part 3 with overcoat 1 is inserted in ply-yarn drill 7 through holes of being opened by expansion again, again plug 2 is pulled out, then lead 8 is passed the hollow structure that always passes overcoat reducing diameter part 3 from the rear end of the hollow structure of overcoat 1, then the reducing diameter part 3 of overcoat 1 being extracted from the through hole of ply-yarn drill 7 both to have made lead 8 be positioned at the endoporus of ply-yarn drill 7, treat that ply-yarn drill 7 shrinks and lead can be blocked under self flexible effect, thereby make things convenient for the assembling of lead and ply-yarn drill, improved production efficiency.
