Abstract
Description
Technical Field
[0001] The utility model relates to the inspection of the sizing dimensions of a stent, making measurement more convenient and the results more accurate. Background Art
[0002] After the filter stent is manufactured, it is necessary to measure the length and diameter of its branch rods. For some filter stents with regular shapes, they can be simply measured with tools. However, for filter stents with special-shaped structures, the conventional tools such as steel straight rulers and vernier calipers are slow in measurement, the number of branch rods of the stent is large and uneven, and the conventional measurement results are inaccurate; moreover, the measurement is easily affected by human factors, and the accuracy of the final result is low. Summary of the Utility Model
[0003] In order to overcome the deficiencies of the prior art, the utility model provides a sizing dimension inspection tooling for a filter stent, which can reduce the influence of human factors, improve the measurement efficiency, and improve the measurement accuracy.
[0004] The technical solution adopted by the utility model is as follows:
[0005] A sizing dimension inspection tooling for a filter stent includes a disc. A through hole is opened at the center of the disc. The through hole is circular, and multiple grooves are also opened around the through hole. The center of the filter stent is a central column, and multiple branch rods extend out around the central column. The center of the filter stent is aligned with the through hole, and each branch rod is located directly above a groove. The outer diameter of the disc is greater than the diameter of the filter stent. The grooves are divided into upper and lower sections. The caliber of the upper section is greater than that of the lower section, and the upper and lower sections are connected. The caliber of the upper section is greater than the diameter of the branch rod of the filter stent, and the caliber of the lower section is less than the diameter of the branch rod of the filter stent.
[0006] The length of the groove is the same as the length of the vertical projection of the two ends of the branch rod above it onto the disc.
[0007] The beneficial effect of the utility model is as follows:
[0008] During the measurement of the stent with this sizing dimension inspection tooling for a filter stent, only need to place it on the tooling. If the stent can fall off from the tooling with the upper limit dimension but cannot fall off from the tooling with the lower limit dimension, it can be explained that the sizing diameter dimension of the stent is qualified, thus reducing the influence of human factors and solving the problems of low measurement efficiency and low measurement accuracy of the existing tooling.

[0012] In the figure: disc 1, through hole 2, groove 3, upper section 4, lower section 5. Specific embodiments
[0013] Refer to Figure 1 , the present utility model relates to a sizing inspection tooling for a filter holder. The inspection tooling includes a disc 1, and a through hole 2 is opened at the center of the disc 1. The through hole 2 is circular, and multiple grooves 3 are also opened around the through hole 2. The position where each groove 3 is opened corresponds to the position of the branch rod of the filter holder to be inspected. The center of the filter holder is a central column, and multiple branch rods extend out from the periphery of the central column.
[0014] The center of the filter holder is aligned with the through hole 2, and each branch rod is located directly above the groove 3. The lengths of the grooves 3 are different, and they match the lengths of the vertical line projections of the two ends of the branch rod above them onto the disc 1. The outer diameter of the disc 1 is slightly larger than the maximum diameter of the filter holder.
[0015] Refer to Figure 2 , the groove 3 is divided into an upper section 4 and a lower section 5. The caliber of the upper section 4 is larger than that of the lower section 5. The upper section 4 and the lower section 5 are connected, and the caliber of the upper section 4 is larger than the diameter of the branch rod of the filter holder, while the caliber of the lower section 5 is smaller than the diameter of the branch rod of the filter holder.
[0016] Refer to Figure 3 , this sizing inspection tooling for a filter holder can be made in various specifications. Multiple sizes of tooling are prefabricated according to the diameter of the branch rod of the filter holder, and a suitable size of tooling is selected to inspect the filter holder. During the inspection, first select a suitable tooling. The caliber of the upper section of the tooling is larger than the diameter of the branch rod of the filter holder, and the caliber of the lower section is smaller than the diameter of the branch rod of the filter holder. Then, align the branch rods of the filter holder with each groove and place it on the tooling. If the holder can slide down from the upper section of the groove and does not slide down from the lower section of the groove, it indicates that the sizing diameter of the filter holder is qualified.
