Problems solved by technology

[0006] The technical problem to be solved by the present invention is the low qualified rate of traditional Chinese medical stents after laser cutting in the prior art. The present invention provides a new automatic compensation processing method for the diameter tolerance of medical stents. The advantages of inconsistent or even out-of-tolerance and scrapping of the final cut stent due to the change of pipe diameter at each point

Embodiment 1

[0037] A method for automatically compensating the diameter tolerance of a medical bracket, the processing equipment used includes a bracket laser cutting machine, a through-beam measuring head and a control system processing center, and the through-beam measuring head is installed on the tube on the two-dimensional motion platform in the bracket laser cutting machine Between the chuck and the clamping bushing near the cutting area of ​​the pipe; the automatic compensation processing method includes the following steps:

[0038] a) The bracket pipe is clamped on the chuck of the laser cutting machine, the chuck is fixed on the rotation axis of the laser cutting machine, and the bracket pipe is between the signal generator and the signal receiver of the beam measuring head;

[0039] b) When the pipe is in the cutting state, the linear axis will drive the rotating axis to move to the right, and the through-beam measuring head will detect the actual pipe diameter of each point in ...

Embodiment 2

[0042] A processing method for automatically compensating the diameter tolerance of a medical stent, in which the through-beam measuring head 2 is installed on a stent laser cutting machine ( Figure 4 Shown) between the pipe chuck 4 on the inner two-dimensional motion platform 10 and the clamping bushing 1 near the cutting area of ​​the pipe, just let the bracket pipe 3 be between the signal generator 8 and the signal receiver 7 of the beam measuring head In between, the bracket pipe is first placed directly on the feeding support module 12, and passes through the rotating shaft 5 on the two-dimensional motion platform, and passes through the pipe chuck 4 in the middle, until the cutting head passing through the right end of the pipe bushing 1 is just below cutting area. Because the bracket pipe 3 passes through the through-beam measuring head first, and then passes through the pipe bushing on the right side, the measurement of the pipe diameter tolerance is performed prior t...

Embodiment 3

[0046] A processing method for automatically compensating the diameter tolerance of a medical stent. The processing equipment for automatically compensating for the caliber tolerance of the medical stent used in the method includes a stent laser cutting machine, a through-beam measuring head and a control system processing center. The through-beam measuring head is installed on the support Between the pipe chuck on the two-dimensional motion platform in the laser cutting machine and the clamping bushing near the cutting area of ​​the pipe; when the pipe is in the cutting state, the bracket pipe is clamped on the chuck, and the chuck is fixed on the rotating shaft On the top, the bracket pipe is between the signal generator and the signal receiver of the beam probe; the linear axis will drive the rotation axis to move to the right, and the beam probe will detect the actual pipe diameter of each point in real time, and the measured actual pipe diameter data It is transmitted to t...

Abstract

The invention relates to an automatic compensating machining method of medical bracket pipe diameter tolerance, which is mainly used for solving the problem that the qualification rate after the laser cutting of the bracket in the prior art is low. The equipment for the automatic compensating machining method of medical bracket pipe diameter tolerance comprises a bracket laser cutter, an opposite irradiating measuring head and a control system processing center; the opposite irradiating measuring head is arranged between a pipe chuck on a two-dimensional motion platform in the bracket laser cutter and a clamping lining sleeve of the pipe close to the cutting area; according to the technical scheme, when the pipe is in a cutting status, the bracket clamp is clamped on the chuck, the chuck is fixed on the rotary shaft, and the bracket pipe is arranged between a signal generator and a signal receiver of the opposite irradiating measuring head, so that the problem is well solved, and the automatic compensating machining method of medical bracket pipe diameter tolerance can be used in the medical bracket pipe measuring device manufacturing industry.

Description

technical field [0001] The invention relates to a processing method for automatically compensating the diameter tolerance of a medical bracket. Background technique [0002] With the rapid development of material science and precision micromachining technology, there are more and more types of medical stent materials. The more common ones are stainless steel 316L, nickel-titanium alloy, cobalt-based alloy, pure iron, magnesium alloy and other metal materials, as well as polymers, etc. non-metallic materials. Because the medical stent expands the vascular wall in the blood vessel to prevent vasoconstriction or even cause various diseases, it is required that the characteristic structure and size of the ribs on the stent be consistent in order to maintain the same tension at each point of the whole stent. The bracket processing technology puts forward higher requirements. Generally, medical stents are processed with seamless pipes. Due to the incomplete development of interv...
