The clamping fixture comprises a whole rotating shaft mounted on an operating board, a clamping head mounted at one end of the whole rotating shaft, and a parallel two-finger clamping mechanism manufactured by adopting magnesium alloy with outstanding vibration reducing performance, wherein the parallel two-finger clamping mechanism is mounted on the operating board and comprises parallel two-finger clamping forceps, a bushing, and a bushing seat for placing the bushing. The clamping fixture for supporting the medical stent tubing, which is disclosed by the invention, has functions of vibration absorption and reduction, so vibration of the tubing, which is produced during the cutting, is reduced, a cut stent satisfies the precision requirement of a client, and the problems that the existing clamping fixture for clamping the stent tubing cannot well absorb and reduce the vibration, and since the stent tubing is easy to wear, destructive damages which cannot be polished away in the follow-up process are formed in the cut stent are solved.
Description
Technical field
The invention belongs to thin-wall pipes laser micro-machining technology field, relate in particular to a kind of anchor clamps that support medical support tubing of in medical support Laser Micro-Machining, using.
Background technology
Medical support is a kind of metal net shaped structure that is implanted to the vascular lesion position, in order to improve the blood flow state of diseased region, blood vessel is played the effect of support.Laser cutting is because technology is simple, speed is fast, have that width of slit is little, the otch depth of parallelism is good, surface roughness is little, dimensional accuracy is high, advantage such as workpiece deformation and heat affected area are little, the accurate micro-workpiece of cutting profile complexity, thereby become the main machining method of medical support processing.Medical support generally can be by the perform the operation sufferer place of implantable intravascular of insertion type, and final and blood vessel applying, and therefore, adding all has strict demand to medical rack surface fineness etc. man-hour.
When adopting the medical support of Laser cutting, laser beam to the cutting process of tubing in the effect of auxiliary process gas, current and cutting force all can cause the vibration of tubing, this vibration can produce very big influence to the finished surface quality of processed medical support tubing, when vibration is bigger, even may cause directly scrapping of processed medical support tubing.
Therefore, in to medical support tubing clamping, need protect medical support tubing by the anchor clamps that employing has vibration damping and a shock sucking function.In the prior art, anchor clamps generally adopt rubber or than the metal material of medical support tubing softness.Yet, adopt gum system cushion block, can not absorb vibration because the gum material is too soft, the trend that has the extent of vibration of making to increase on the contrary, while rubber is ageing hardening gradually, thereby loses the ability that alleviates vibration; And when adopting backing metal,, can not absorb vibration protection tubing because metal material is really up to the mark.This shows,, all can exist to produce vibration, produce problem such as abnormal sound that vibration damping, shock attenuation result are bad than metal, plastics or the gum anchor clamps of medical support tubing softness.Therefore, be necessary to develop research, solve above problem so that a kind of anchor clamps that support medical support tubing when being used for medical support Laser Micro-Machining to be provided.
Summary of the invention
For addressing the above problem, the object of the present invention is to provide a kind of anchor clamps with medical support tubing of support of good vibration damping, shock sucking function.
For achieving the above object, technical scheme of the present invention is:
A kind of anchor clamps that support medical support tubing, the chuck, that include the rotating shaft integral body that is installed on the operating desk, is installed on the whole end of rotating shaft parallel two refers to clamping devices by what the exsertile almag of damping property was made; Wherein, described parallel two refer to that clamping device is installed on the operating desk, and it includes parallel two and refers to clamp, lining and the liner clamp of settling lining.
Further, described parallel two refer to that clamp includes clamp and following clamp, and tubing is held between the upper and lower tongs.。
Further, described go up clamp and be respectively arranged with tubing on clamp and the inner surface that tubing contacts down protect cushion block.
Further, described parallel two refer to that clamping device is provided with the up-down adjustment screw in its top.
Further, described parallel two refer to that clamping device is provided with the left and right adjusting screw in the one side.
Further, described rotating shaft integral body has two frees degree, can drive tubing and rotate when chuck clamps tubing, and can carry out horizontal rectilinear motion, along with the cutting of laser cutting head, to realize the tubing feed motion.
Further, described tubing protection cushion block is installed in parallel two and refers on the inner layer surface of upper and lower clamp of clamps.
The anchor clamps that the present invention supports medical support tubing have the function of absorbing and vibration damping, reduce the vibration of tubing when cutting, the support that cuts out meets the required precision that the client proposes, and well absorbing of anchor clamps, vibration damping and the support tubing that has solved existing clamp bracket tubing wearing and tearing easily makes support after the cutting produce the problem that destructiveness that subsequent technique can't polishing falls is damaged.
