The outside dimension of this device design cylinder 23 is selected an optimum point between material cost and processing cost.Its length has requirement: after flexible hose is inserted in glass tube appropriate length, circular hole 22 must expose flexible hose, is beneficial to asessory shaft is extracted from glass tube and flexible hose.
2 technical schemes to sum up, have and what time need explanation:
1) the first cylindrical end face 1 in technical scheme one is to the total length of 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 designly, and changeover portion outside dimension is only slightly slightly larger than glass tube external diameter, and conical degree of conical surface and conical surface segment length are suitable, plug in sebific duct time ratio be easier to, laborsaving.
3) guide section external diameter and length dimension are moderate, and outside dimension is slightly slightly less than glass tube internal diameter.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, can reach good surface smoothness, preferably there is self lubricity, such as materials such as POM.
Based on above-described embodiment the present invention, also provide a kind of technical scheme that replaces, 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.On the end face 48 of changeover portion 45, be provided with the via hole 47 that runs through whole device, at end face 48 edges of changeover portion 45, be provided with fillet 46, on the end face being connected with linkage section 43 at cylinder 41, be 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 is 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 to glass tube outer wall.The purpose of design of through hole 47 is inserted glass tube in auxiliary sleeve.In order to make sebific duct can insert easily the conical surface section 44 of auxiliary sleeve, on changeover portion, design fillet 46.
The concrete step of using comprises:
Step S41: flexible hose is inserted to auxiliary sleeve changeover portion and conical surface suitable length;
Step S42: glass tube is inserted to auxiliary sleeve from through hole, and make glass tube prop up gently flexible hose;
Step S43: make glass tube prop up gently flexible hose, more slowly flexible hose is taken off from the conical surface of auxiliary sleeve, allow flexible hose be attached on glass tube outer wall; When being attached to flexible hose on glass tube, reach appropriate length, can pinch the sebific duct being attached on glass tube, pinch auxiliary sleeve simultaneously, firmly auxiliary sleeve is extracted from sebific duct.
What deserves to be explained is, through hole 47 diameters on auxiliary sleeve are 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: flexible hose internal diameter is expanded, make glass tube prop up gently after flexible hose, 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 auxiliary sleeve is while inserting flexible hose, is 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, can reach good surface smoothness, preferably there is self lubricity, such as materials such as POM.
Patent CN202219596U is the profile that designs as required reamer, and the soft pipeline moulding of Fast Heating, before temperature does not also lower, rapidly glass tube is inserted to soft pipeline, after it is down to room temperature, cooling recovery distortion, soft pipeline fits tightly with glass tube again.With respect to now widely used method and the patent CN202219596U that need not any aid directly docks flexible hose and glass tube, the present invention has following advantage:
1) apparatus structure is simple, and the heating system complex of patent CN202219596U.
2) only design cost, processing cost of cost, simple in structure because of it, 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 is used simply, low to operating personnel's stock of knowledge requirement, and first the heating of patent CN202219596U requires operating personnel to have certain understanding to system, secondly need possess the thermal deformation knowledge of the material of flexible hose.
4) yield rate is high, and apparatus of the present invention only utilize the elastic deformation of flexible hose to realize being connected of flexible hose and glass tube; And the heating of patent CN202219596U is used principle of expanding with heat and contracting with cold, probably the raw-material structure of flexible hose is damaged, 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 are simple in structure, easy to carry, can use in any place, are applicable to after-sale service; And the heater of patent CN202219596U is not easy to carry, heating source is used electrical heating, after-sales service poor practicability.
6) the present invention can well evade flexible hose by the sharp corner angle scratch damage risk of glass tube end face, also can not produce and scrape chip, and then cause fluid system obstruction, stuck abnormal.
Should be understood that, application of the present invention is not limited to above-mentioned giving an example, and for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of claims of the present invention.
