Description
Technical field
This utility model relates to a kind of rustless steel pipe fixing device, belongs to pipe fitting processing technique field.
Background technology
Stainless steel tube is widely used in conveyance conduit and the machine structural parts of the industry such as oil, chemical industry, medical treatment, food, light industry, machinery instrument.In current tap water supply industry, also widely used stainless steel tube is as water supply line, the advantage with health corrosion-resistant, clean.But the cost of stainless steel tube material is high, and particularly the tube wall of stainless steel tube is more thick, and the cost spent is more high.Therefore the stainless steel tube of practical application is usually the thin-wall stainless steel that 2-3mm is thick.Although adopting this thin-wall stainless steel can reduce cost, but due to too thin, cause hardness not and plasticity is high, add difficulty chip breaking in man-hour, and the course of processing of usual thin-wall stainless steel does not allow to scratch the surfaces externally and internally of stainless steel tube, if inner surface scratches or damages, it is easy to breed bacteria impact cleaning, if outer surface scratches, affect attractive in appearance.This causes that the difficulty of processing of thin-wall stainless steel is big, it is desirable to high, difficult fixing.Owing to hardness is inadequate, the easy degeneration of the great efforts fixing when turnery processing, dynamics is little to be difficult to meet machining accuracy.
Utility model content
The purpose of this utility model is in that to solve the problems referred to above, it is provided that a kind of novel rustless steel pipe fixing device.
Rustless steel pipe fixing device described in the utility model includes claw, and stainless steel tube is clamped by this claw in one end of stainless steel tube；Pad it is provided with, for preventing claw from being crushed by the outer surface of stainless steel tube between claw and stainless steel tube；The one end contacted with claw at stainless steel tube is provided with locating piece, and this locating piece is arranged on inside stainless steel tube, leaves the gap of 0.05 millimeter between excircle and the inner surface of stainless steel tube of locating piece；Fill in after the other end of stainless steel tube is provided with elasticity, after elasticity, the size of plug is identical with locating piece with material, the nose circle face of plug is provided with the conical bore of 60 degree after elasticity, it is provided with rolling center in this conical bore, this rolling center has the tip mated with conical bore size, rolling center is fixed in the length stop block be arrangeding in parallel with stainless steel tube, locating piece and after elasticity plug between be provided with push rod, be provided with space washer between push rod and locating piece.
Compared with prior art, technical solutions of the utility model provide the benefit that:
Stainless steel tube fixture structure described in the utility model is reasonable, the locating piece that adopts, the parts that every surfaces externally and internally with stainless steel tube such as plug, push rod and pad contacts after elasticity all adopt polytetrafluoroethylplastic plastic, owing to polytetrafluoroethylplastic plastic is softer, surfaces externally and internally thus without mill flower or folder flower stainless steel tube, claw only plays the effect of centering and auxiliary clamp, it is real that what play fixation is the cutting force of the top power of tailstock and lathe tool, center rest need not be adopted, meet the turnery processing requirement to location.
Accompanying drawing explanation
Fig. 1 is the structural representation of rustless steel pipe fixing device described in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical scheme in this utility model is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under the premise not making creative work, broadly fall into the scope of this utility model protection.
As it is shown in figure 1, rustless steel pipe fixing device described in the utility model includes claw 1, stainless steel tube is clamped by this claw in one end of stainless steel tube 9；Pad 2 it is provided with, for preventing claw from being crushed by the outer surface of stainless steel tube between claw and stainless steel tube；One end that stainless steel tube contacts with claw is provided with locating piece 3, and this locating piece is arranged on inside stainless steel tube, leaves the gap of 0.05 millimeter between excircle and the inner surface of stainless steel tube of locating piece；6 are filled in after the other end of stainless steel tube is provided with elasticity, after elasticity, the size of plug is identical with locating piece with material, the nose circle face of plug is provided with the conical bore of 60 degree after elasticity, rolling center 7 it is provided with in this conical bore, this rolling center has the tip mated with conical bore size, rolling center is fixed in the length stop block 8 be arrangeding in parallel with stainless steel tube, locating piece and after elasticity plug between be provided with push rod 5, be provided with space washer 4 between push rod and locating piece.
The operation principle of rustless steel pipe fixing device described in the utility model is: first locating piece 3 is filled in one end of stainless steel tube 9, put into space washer 4 and push rod 5, push rod 5 can be chosen according to the length of stainless steel tube 9, then after the other end of stainless steel tube 9 puts into elasticity, 6 are filled in, the cylindrical of stainless steel tube 9 is clamped with claw 1, the tailstock screw mandrel being connected with claw drives claw to move right, the position swell contacted with rolling center 7 is filled in, it is achieved fixedly secured between claw 1 and rolling center 7 by stainless steel tube 9 after making elasticity.
The locating piece 3 that adopts in rustless steel pipe fixing device described in the utility model, the parts that every surfaces externally and internally with stainless steel tube such as plug 6, push rod 5 and pad 2 contacts after elasticity all adopt polytetrafluoroethylplastic plastic, owing to polytetrafluoroethylplastic plastic is softer, surfaces externally and internally thus without mill flower or folder flower stainless steel tube, claw only plays the effect of centering and auxiliary clamp, it is real that what play fixation is the cutting force of the top power of tailstock and lathe tool, center rest need not be adopted, meet the turnery processing requirement to location.
In sum, being this utility model embodiment content, and obvious embodiment of the present utility model is not limited to that, it according to different application environment, can utilize functional realiey corresponding demand of the present utility model.
