Abstract
The utility model relates to the technical field of connectors, in particular to an expanding type adjustable core rod. The expanding type adjustable core rod comprises an expansion shaft, wherein the tail portion of the expansion shaft is provided with the protruding portion, a shaft body at the front portion of the expansion shaft is provided with an outer threaded section, an expansion sleeve and a taper sleeve sequentially sleeve the expansion shaft, one end of the expansion sleeve is supported on the protruding portion, the other end of the protruding portion is supported on the conical face of the front end of the taper sleeve, and a nut is screwed on the outer threaded section to lock and fix the taper sleeve tightly. By adopting the expanding structure, the adjustable core rod is tightly matched with a workpiece without a gap, and processing errors are decreased. By adopting the adjustable structure, the expanding type adjustable core rod is good in universality, can be suitable for various workpieces and has no special requirements for the matching face size. The expanding type adjustable core rod is simple, reliable, low in fault rate and convenient to dismount and maintain.
Description
Technical field
The utility model relates to connector technical field, specifically the adjustable plug of a kind of expansion type.
Background technology
Along with industrial expansion, the precision of all kinds of process equipments is also improving constantly, and market is also more and more higher to Product Precision requirement simultaneously, and this just has higher requirement to the processing method in machining.In the higher manufacturing procedure of the required precision such as mill, roll flute outside, conventionally to use this frock of plug.Traditional plug is to coordinate by cylindrical and end face endoporus and end face higher with workpiece accuracy, because plug needs repeated disassembled and assembled, so be typically designed to matched in clearance, adds mismachining tolerance and wearing and tearing, and the gap between plug and workpiece is inevitable.The gap that plug coordinates with workpiece will cause the generation of error, thereby causes the decline of workpiece accuracy.On the other hand, traditional plug is because size is fixed, so wide usage is very low, often needs to make a lot of plugs, causes waste, increases cost.
Summary of the invention
The utility model, for the problems referred to above, provides a kind of expansion type adjustable plug, and this plug easy accessibility, can be applicable to various workpiece, and coordinates closely and can amplitude peak reduce the mismachining tolerance being caused by frock.
According to the technical solution of the utility model: the adjustable plug of a kind of expansion type, it is characterized in that: comprise main axis of dilatation, described main axis of dilatation afterbody has protuberance, the anterior axis body of main axis of dilatation is provided with one section of external thread section, expansion sleeve and tapered sleeve are set on described main axis of dilatation successively, described expansion sleeve one end is supported on described protuberance, and the expansion sleeve other end is supported on the described tapered sleeve nose circle conical surface, and nut screwing clamping is locked tapered sleeve on described external thread section.
As further improvement of the utility model, described expansion sleeve two ends inner sides is respectively provided with a conical socket, and expansion sleeve one side conical socket stretching is on protuberance, and expansion sleeve opposite side conical socket stretching is on described taper seat.
As further improvement of the utility model, the working face of described protuberance is conical.
As further improvement of the utility model, the described main axis of dilatation both ends of the surface centre of gyration is respectively offered a centre bore.
As further improvement of the utility model, described expansion sleeve is eight equal parts structure along the circumferential direction.
Technique effect of the present utility model is: adopted expansion type structure, coordinated tight gapless with workpiece, reduced mismachining tolerance; Adopted adjustable structure, wide usage is strong, applicable various workpiece, to mating surface size without specific (special) requirements; This plug is simple and reliable, and fault rate is little, dismounting, easy to maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A cutaway view in Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further described.
In Fig. 1, Fig. 2, comprise main axis of dilatation 1, expansion sleeve 2, tapered sleeve 3, nut 4, centre bore 5, external thread section 6, protuberance 7, taper seat 8, conical socket 9 etc.
As shown in Figure 1 and Figure 2, the utility model is the adjustable plug of a kind of expansion type, comprise main axis of dilatation 1, described main axis of dilatation 1 afterbody has protuberance 7, the anterior axis body of main axis of dilatation 1 is provided with one section of external thread section 6, and expansion sleeve 2 and tapered sleeve 3 are set on described main axis of dilatation 1 successively, and described expansion sleeve 2 one end are supported on described protuberance 7, expansion sleeve 2 other ends are supported on the described tapered sleeve 3 nose circle conical surfaces 8, and nut 4 is tightened against on described external thread section 6 tapered sleeve 3 is locked.
Described expansion sleeve 2 inner sides, two ends are respectively provided with a conical socket 9, and expansion sleeve 2 one side conical socket stretchings are on protuberance 7, and expansion sleeve 2 opposite side conical socket stretchings are on described taper seat 8.
The working face of described protuberance 7 is conical.
The described main axis of dilatation 1 both ends of the surface centre of gyration is respectively offered a centre bore 5.
As shown in Figure 2, described expansion sleeve 2 is eight equal parts structure along the circumferential direction.
The course of work of the present utility model is as follows: during use, pack main axis of dilatation 1 into expansion sleeve 2, expansion sleeve 2 other ends pack tapered sleeve 3 into, and at external thread section 6, is screwed into nut 4 and withstands tapered sleeve 3, and expansion sleeve 2 cylindrical alignment pieces are needed to cooperation position.Fastening nut 4, promotes tapered sleeve 3 and travels forward, and by the acting in conjunction of two pyramidal structures to two ends conical socket 9 on expansion sleeve 2 on tapered sleeve 3 and main axis of dilatation 1, expansion sleeve 2 is strutted; Expansion sleeve 2 eight equal parts evenly expand, and the corresponding mating surface of cylindrical and workpiece is adjacent to, by nut 4 is applied after enough screwing forces, expansion sleeve 2 completely and workpiece be adjacent to, complete clamping.During dismounting, only nut 4 need be loosened, expansion sleeve 2 can unclamp, and takes out workpiece and completes dismounting.
The utility model has adopted expansion type structure, coordinates tight gapless with workpiece, has reduced mismachining tolerance; Adopted adjustable structure, wide usage is strong, applicable various workpiece, to mating surface size without specific (special) requirements; This plug is simple and reliable, and fault rate is little, dismounting, easy to maintenance.
