This apparatus design conical surface body section, flexible hose endoporus is extended to suitable dimension by conical surface section, and cone angle design need be suitable for, be beneficial to flexible hose plug, be designed to 15 ° ~ 22 °, conical surface section surface smoothness requirements is higher, surface roughness be Ra1.6 and more than.
Design transition section connects guide section and conical surface section, is to reduce frictional force, and transition section length is designed to 0.5 ~ 2mm, external diameter 0.6-1mm larger than glass tube external diameter size, and limits to suitable tolerance, surface roughness be Ra1.6 and more than.
The outside dimension of this apparatus design cylinder 23 selects an optimum point between material cost and processing cost.Its length has requirement: after flexible hose is inserted in glass tube appropriate length, and circular hole 22 must expose flexible hose, is beneficial to and is extracted from glass tube and flexible hose by asessory shaft.
To sum up 2 technical schemes, have and what time need to illustrate:
1) total length of the in technical scheme one first cylindrical end face 1 to conical surface body 6; The length of the cylinder 23 in technical scheme two, need determine according to reality flexible hose length used.
2) the changeover portion outside dimension in two schemes and conical degree of conical surface size need reasonable in design, and changeover portion outside dimension is only greater than glass tube external diameter slightly, conical degree of conical surface and conical surface segment length suitable, plug in sebific duct time ratio be easier to, laborsaving.
3) guide section external diameter and length dimension moderate, outside dimension is less than glass tube internal diameter slightly.If guide section is long, due to reasons such as auxiliary rod mismachining tolerances, axiality is inadequate, and asessory shaft and glass tube have radial load, may damage glass tube.
4) auxiliary rod material therefor, need tool can processing type good, good surface smoothness can be reached, preferably there is self lubricity, the materials such as such as POM.
Also provide one to replace technical scheme based on above-described embodiment the present invention, Fig. 4 is shown in by structure chart.Comprise the cylinder 41, linkage section 43, conical surface section 44 and the changeover portion 45 that connect successively.The end face 48 of changeover portion 45 is provided with the via hole 47 running through whole device, end face 48 edge of changeover portion 45 is provided with fillet 46, the end face that cylinder 41 is connected with linkage section 43 is provided with fillet or chamfering 42.
When flexible hose is undamaged be socketed in glass tube appropriate length after, pinch cylinder 41 and fillet chamfering 42, firmly auxiliary sleeve extracted from flexible hose.Being designed for of conical surface section 44 and changeover portion 45 expands its internal diameter to appropriate size before flexible hose is socketed in glass tube outer wall.Glass tube inserts in auxiliary sleeve by the purpose of design of through hole 47.In order to the conical surface section 44 making sebific duct can insert auxiliary sleeve easily, changeover portion designs fillet 46.
Concrete use step comprises:
Step S41: flexible hose is inserted auxiliary sleeve changeover portion and conical surface suitable length;
Step S42: glass tube is inserted auxiliary sleeve from through hole, and make glass tube prop up flexible hose gently;
Step S43: make glass tube prop up flexible hose gently, more slowly the conical surface of flexible hose from auxiliary sleeve is taken off, allow flexible hose be attached on glass tube outer wall; Reaching appropriate length when being attached to flexible hose on glass tube, the sebific duct be attached on glass tube can be pinched, pinch auxiliary sleeve simultaneously, firmly auxiliary sleeve is extracted from sebific duct.
What deserves to be explained is, through hole 47 diameter on auxiliary sleeve is a bit larger a little than glass tube external diameter size, and through hole adds notes deviation from circular from and coaxiality error man-hour, is convenient to glass tube to insert.The external diameter design of changeover portion 45 is wanted rationally, the optimum size of changeover portion external diameter is: expanded by flexible hose internal diameter, after making glass tube prop up flexible hose gently, the end face 48 of glass tube end face and changeover portion has a bit of length, operator can pinch glass tube, is so convenient to auxiliary sleeve to extract from flexible hose; And during auxiliary sleeve insertion flexible hose, be easier to.Conical surface section 44 can be designed to the conical surface, also can be designed to the face of cylinder, is convenient to the plug of flexible hose.Auxiliary sleeve material therefor, also need tool can processing type good, good surface smoothness can be reached, preferably there is self lubricity, the materials such as such as POM.
Patent CN202219596U is the profile designing reamer as required, and the soft pipeline of Fast Heating is shaping, before temperature does not also lower, rapidly glass tube is inserted soft pipeline, be down to after room temperature until it, cooling recovers distortion, and soft pipeline fits tightly with glass tube again.Need not directly dock method and the patent CN202219596U of flexible hose and glass tube by any aid relative to now widely used, the present invention has following advantage:
1) apparatus structure is simple, and the heating system complex of patent CN202219596U.
2) cost only design cost, processing cost, because its structure is simple, these two expenses are low, without use cost; And the heating that patent CN202219596U proposes, design cost, processing cost and use cost are high.
3) operation uses simple, require low, and first the heating of patent CN202219596U requires that operating personnel have certain understanding to system, secondly need possess the thermal deformation knowledge of the material of flexible hose to the stock of knowledge of operating personnel.
4) yield rate is high, and apparatus of the present invention only utilize the elastic deformation of flexible hose to realize the connection of flexible hose and glass tube; And the heating of patent CN202219596U uses principle of expanding with heat and contracting with cold, probably damage the raw-material structure of flexible hose, and then cause after flexible hose cools back complex deformation, the sealing of flexible hose and glass tube has problems.
5) apparatus of the present invention structure is simple, easy to carry, can use in any place, is applicable to after-sale service; And the heater of patent CN202219596U is not easy to carry, heating source uses electrical heating, after-sales service poor practicability.
6) the present invention well can evade flexible hose and damaged risk by the sharp corner angle scratch of glass tube end face, also can not produce and scrape chip, and then causes that fluid system blocks, stuck exception.
Should be understood that, application of the present invention is not limited to above-mentioned citing, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to claims of the present invention.
