Description
Technical field
The utility model relates to the little process equipment of support field, is specifically related to a kind of bush structure.
Background technology
The material of medical support generally comprises nonmetallic materials such as metallic supports such as stainless steel 316L, Nitinol, cobalt-base alloys, pure iron and macromolecule etc.These materials generally can be processed to diameter 5 ± 0.01 mm (the general diameter of coronary artery bracket is between 1mm ~ 2mm), wall thickness 0.2mm with interior seamless pipe.Consider that medical support generally can be through the sufferer place of insertion type operation implantable intravascular, and final and blood vessel applying, therefore, medical support has strict demand to rack surface fineness etc.General medical support is through after the Laser Micro-Machining; Need carry out a plurality of process procedures such as ultrasonic waves for cleaning, polishing, detection, assembling; Guarantee the fineness that final rack surface is good; Except that improving the fineness through the polishing after the support Laser Micro-Machining, also need guarantee in the support Laser Micro-Machining process, can not damage the destructiveness that support tubing causes follow-up glossing to be difficult to dispose.Cause scrapping of institute's processing support for fear of this kind situation occurring; Support Laser Micro-Machining equipment need be considered to design suitable anchor clamps and guarantee outside the support cut point place tubing stability, will consider that also this anchor clamps can not cause support in the Laser Micro-Machining process, to cause destructive damages such as scratch.
In the existing support Laser Micro-Machining equipment, adopt bush structure as shown in Figure 1 to come clamp bracket tubing usually: this lining 1 length overall 40mm, different linings need be changed according to different support tubing specification in the aperture of endoporus 11.There is following shortcoming in this lining 1: 1) support is in cutting process, and lining 1 can suitably increase the stability of cut point place tubing owing to cooperate with support tubing through long distance.But because the endoporus 11 of lining is longer, the length of fit of corresponding increase of inevitable requirement support tubing and lining 1 can cause more tubing waste, and this structure is unfavorable for that support tubing inserts the lining 1 from left end smoothly.2) because this lining 1 is to rely on growth lining 1 and support tubing length of fit that the stability of cut point place tubing is provided, the support tube surfaces is increased by the risk of scratch, and the endoporus difficulty of processing of lining itself also can increase, cost is higher.3), generally can adopt soft partially red copper of material or beryllium copper as lagging material, and this type material is through cooperating with the long-term of support tubing for the ease of the processing of this lining 1; Make endoporus 11 two ends of lining 1 be easy to worn into " horn mouth "; In case similar defective occurs,, should " horn mouth " can become big more more like untimely replacing; Directly cause support tubing clamping stability to continue to reduce; Cause unavailable at last and necessary the replacing, cause waste, or even bring uncertain factor for the control of the support quality of production.
Lining depends on the corresponding lining that is fit to of support tubing to certain specification usually with the cooperation of support tubing.In case the support tube outer diameter changes, lining is also wanted corresponding change.In addition, because the inconsistency of support tubing tolerance, the lining of the corresponding plurality of specifications of the support tubing of a certain specification has increased cost undoubtedly greatly.
The utility model content
The purpose of the utility model is, a kind of combined type bush structure that is applicable to the support cutting equipment is provided, and solves above technical problem.
The technical problem that the utility model solved can adopt following technical scheme to realize:
A kind of combined type bush structure that is applicable to the support cutting equipment comprises a lining main body, it is characterized in that, has a V-shape groove on the outer wall of said lining main body, and said V-shape groove is along the length direction setting of said lining main body;
The V-shape groove of said lining main body top be provided with one be used to compress support tubing hold down gag.
The utility model adopts exact constraint principles to carry out the clamping location of support tubing.During use support tubing is arranged in the V-shape groove, carries out the clamping location of support tubing.The utility model adopts the V-shape groove to carry out the location of support tubing, and utilizes hold down gag that tubing is compressed, and compares the difficulty of processing of pass lining in can reducing with traditional mode of in the lining main body, establishing endoporus.In addition, the utility model can also solve same support tubing tolerance inconsistency, and a lining main body can adapt to the support tubing of different size, and is applied widely, greatly reduces the cost of support Laser Micro-Machining equipment.
Said hold down gag comprises that one is arranged on the briquetting holder of said V-shape groove top, is provided with a briquetting between said briquetting holder and the said V-shape groove, and said briquetting connects said briquetting holder through adjustment screw.When the utility model used, briquetting was pushed down support tubing, and thrust is regulated through adjustment screw, so that the V-shape groove adapts to different support tubing.
When using adjustment screw to regulate thrust, for fear of because of regulating the excessive support tubing that damages, on adjustment screw, also be provided with a spring, so that when regulating thrust, protective cradle tubing.
Said hold down gag can comprise two or at least two adjustment screw.
Said combined type bush structure also comprises a lining mount pad, and said lining mount pad top is provided with a mount pad groove, and said lining main body is arranged in the said mount pad groove, and the V-shape groove of said lining main body up;
Said briquetting holder is fixed on the said lining mount pad.Can lining main body and briquetting holder be fixed through the lining mount pad.
Said lining main body can adopt die steel material to process.So that it is the integral hardness of lining main body is higher, all higher than general support tubing.In the support cutting process, the lining main body of the utility model can not be worn basically like this, has effectively prolonged the service life of lining main body.
Said lining main body can adopt the red copper alloy to process.Red copper alloy material processing characteristics is good, can easily process the V-shape groove.
Said lining main body can also adopt beallon to process.Beallon hardness is moderate, and processing characteristics is slightly poorer than red copper alloy, but is difficult in use being worn, and same lining main body can be used the long period, can be used for making high accuracy, the long-term lining main body of using.
Consider that support tubing continues to cooperate with the lining main body in the Laser Micro-Machining process; Caused the risk of support quality of production decline with the lining main body because of contacting with support tubing for a long time to be worn by the scratch risk in order to reduce the support tube surfaces; The length of said V-shape groove is not more than 10mm, has so also reduced the difficulty of processing of lining main body self.
Beneficial effect: owing to adopt technique scheme, the utility model can adapt to the support tubing cutting of different size, has reduced the cost of support Laser Micro-Machining equipment.
