Abstract
The utility model relates to oil return pipe production equipment field, especially a kind of wrinkle resistant sheath assembly tool of oil return pipe, it comprises expansion segment and linkage section, described expansion segment is conical structure or circular cone structure, described linkage section is cylindrical structural, the bottom surface of expansion segment is connected with linkage section end face, and both are structure as a whole; The center line of described linkage section overlaps with the center line of expansion segment; The diameter of linkage section is less than or equal to the internal diameter of oil return pipe, and the basal diameter of expansion segment is greater than the external diameter of oil return pipe, and the end face diameter of expansion segment is less than the external diameter of oil return pipe.The wrinkle resistant sheath assembly tool of this oil return pipe, easy to use, effectively can reduce the frictional force between sheath and oil return pipe, thus reduce the wrinkling phenomenon of sheath, improve assembling property and packaging efficiency, minimizing is done over again.
Description
Technical field
The utility model relates to oil return pipe production equipment field, especially a kind of wrinkle resistant sheath assembly tool of oil return pipe.
Background technology
At present when oil return pipe production process, finally all need to assemble sheath on oil return pipe, prevent oil return pipe from use phenomenons such as being slided brokenly occurring; And in existing assembling process, be all directly sheath is set on oil return pipe, owing to there is certain frictional force between oil return pipe and sheath, easily cause sheath wrinkling, finally cause product to do over again, reduce production efficiency, and the waste of part material can be caused.
Utility model content
The purpose of this utility model is deficiency in order to solve above-mentioned technology and provides a kind of structure simple, effectively can reduce sheath produces the oil return pipe of wrinkling on oil return pipe wrinkle resistant sheath assembly tool in assembling process after using.
In order to achieve the above object, the wrinkle resistant sheath assembly tool of the oil return pipe designed by the utility model, it comprises expansion segment and linkage section, described expansion segment is conical structure or circular cone structure, described linkage section is cylindrical structural, the bottom surface of expansion segment is connected with linkage section end face, and both are structure as a whole; The center line of described linkage section overlaps with the center line of expansion segment; The diameter of linkage section is less than or equal to the internal diameter of oil return pipe, and the basal diameter of expansion segment is greater than the external diameter of oil return pipe, and the end face diameter of expansion segment is less than the external diameter of oil return pipe.
Technique scheme, in use, only linkage section need be set in one end of oil return pipe, then sheath be inserted in from expansion segment, directly be enclosed within oil return pipe after the expansion of expansion segment, more convenient to operate, and the frictional force of sheath after the expansion and between oil return pipe reduces greatly, thus the phenomenon that can effectively avoid sheath wrinkling, improve performance and the efficiency of assembling, reduce phenomenon of doing over again, enhance productivity; Expansion segment preferred structure is circular cone structure simultaneously, the top because of expansion segment effectively can be avoided too sharply to cause jacket inner wall impaired, can improve the security of processing assembling simultaneously.
The wrinkle resistant sheath assembly tool of the oil return pipe that the utility model obtains, easy to use, effectively can reduce the frictional force between sheath and oil return pipe, thus reduce the wrinkling phenomenon of sheath, improve assembling property and packaging efficiency, minimizing is done over again.
