Description
Technical Field
The utility model relates to a threading instrument field, concretely relates to supplementary threading instrument for rubber spare.
Background
Along with the gradual development of automobiles, electronic components on the automobiles are more and more, and therefore wire harnesses on the automobiles are also more and more. The wire harness on the automobile usually needs to pass through the metal structure of the automobile body, and in order to prevent the metal sheet metal structure of the automobile from damaging the wire harness, a rubber protective sleeve needs to be arranged on the metal sheet metal part of the automobile, and then the wire harness passes through the rubber sleeve, so that the wire harness is protected. However, in the actual installation process, the aperture of the rubber protective sleeve is often slightly smaller than the diameter of the wiring harness or is just equal and has no movable gap, so that the wiring harness is difficult to directly pass through the rubber part in the assembly process. In addition, the large friction between the rubber piece and the wiring harness brings great trouble to the threading. Therefore, how to rapidly penetrate the wiring harness through the rubber piece is an urgent problem to be solved.
Disclosure of Invention
To the weak point among the above-mentioned prior art, the utility model provides an supplementary threading instrument for rubber spare, its simple structure, convenient operation for it is easier that the pencil passes the rubber spare.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
an auxiliary threading tool for rubber parts, characterized in that: the guide head is provided with a through center hole, the front part of the guide head is of a conical structure, the rear part of the guide head is provided with a step shaft, a small-diameter section of the step shaft is inserted into the center hole at the front end of the separate reamer, and the front end of the separate reamer and the large-diameter section of the step shaft are in smooth transition.
Furthermore, the separated reamer comprises a left semicircular groove and a right semicircular groove which are oppositely buckled into a cylindrical structure, wherein the left semicircular groove and the right semicircular groove are provided with sliding groove structures on a joint surface, so that the left semicircular groove and the right semicircular groove can be separated in a sliding mode relatively to the axial direction, and radial relative sliding is limited.
Furthermore, the rear ends of the left semicircular groove and the right semicircular groove are respectively provided with a handle arranged in the radial direction.
Furthermore, the outer wall of the separated reamer and the inner wall of the central hole are smooth surfaces.
The beneficial effects of the utility model include: simple structure, convenient operation has solved the pencil and has directly passed the big problem of the rubber spare degree of difficulty, is showing the assembly efficiency of pencil that improves on the car, has reduced workman's intensity of labour.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments and accompanying drawings.
An auxiliary threading tool for rubber members as shown in figures 1-2 comprises a separate reamer 1 and a guide head 2. The separated reamer 1 is provided with a through center hole, the outer wall and the inner wall of the separated reamer are smooth surfaces, and the wire harness can easily penetrate through the center hole of the separated reamer 1. The front part of the guide head 2 is of a smooth conical structure, the rear part of the guide head is of a smooth step shaft, a small-diameter section of the step shaft is inserted into a central hole in the front end of the separated reamer 1, and the front end of the separated reamer 1 and a large-diameter section of the step shaft are in smooth transition. The guide head 2 can guide the separated reamer 1 to easily penetrate through the hole in the rubber part, and has a certain reaming effect when the hole is small. After the split reamer 1 passes through the hole in the rubber part, the guide head 2 is taken down, namely the wire harness can penetrate into the wire harness from the central hole of the split reamer 1, and the split reamer 1 is taken down after the wire harness completely passes through the rubber part.
In the embodiment shown in fig. 2, the split reamer 1 includes a left semicircular groove 3 and a right semicircular groove 4 that are relatively buckled into a cylindrical structure, wherein the left semicircular groove 3 and the right semicircular groove 4 have a sliding groove structure on a joint surface, so that the left semicircular groove 3 and the right semicircular groove 4 can be separated by sliding in an axial direction, and the radial relative sliding is limited. Thereby ensuring that the split reamer 1 is structurally stable when passing through the rubber member and can be easily pulled out of the rubber member individually or simultaneously when the threading is completed.
Further, for the convenience of insertion and extraction, the rear ends of the left semicircular groove 3 and the right semicircular groove 4 are respectively provided with a handle 5 arranged in the radial direction.
The technical solutions provided by the embodiments of the present invention are described in detail above, and the principles and embodiments of the present invention are explained herein by using specific examples, and the descriptions of the above embodiments are only applicable to help understand the principles of the embodiments of the present invention; meanwhile, for a person skilled in the art, according to the embodiments of the present invention, there may be variations in the specific implementation manners and application ranges, and in summary, the content of the description should not be construed as a limitation to the present invention.
