Description
Technical Field
[0001] This utility model relates to the field of stent technology, specifically a stent angle testing fixture. Background Technology
[0002] The support frame is subjected to significant forces during operation, thus requiring high structural strength and installation fixation strength. The structural strength of existing support frames is determined by the manufacturing process, while the installation fixation strength is determined by the assembly precision and standardized operation during installation. (See attached instruction manual.) Figure 4 The bracket shown includes a base and two wing plates, totaling three mounting surfaces. These three mounting surfaces are at three different angles. During installation, each surface must be aligned with its corresponding angle to ensure the strength of the installation. Due to various objective factors during the production process, angle errors may occur. Therefore, random inspections are necessary to monitor the product condition at all times and adjust any errors promptly to ensure product quality. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a bracket angle testing fixture, which is used to conveniently detect whether the angles of multiple mounting surfaces on the bracket meet the standards.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figure 1-4 As shown, this utility model provides a technical solution: a bracket angle testing fixture, including a fixed base 1. The fixed base 1 includes a raised base 101 whose width is adapted to the base plate 201 and a sunken base 102 adapted to the width of the entire bracket 2. The raised base 101 and the sunken base 102 are an integral structure, which is adapted to the feature that the bottom of the wing plate 202 is lower than the bottom of the base plate 201.
[0023] The fixed base 1 has multiple positioning posts 3 that are vertically installed on the base plate 201 of the bracket 2 and can be movably inserted into the vertical mounting holes. There are multiple positioning posts 3, and they correspond to the number and position of the vertical mounting holes on the base plate 201. The positioning posts 3 include two tall guide positioning posts 301 and multiple short base positioning posts 302. Based on the principle that two positioning posts 3 can position one bracket 2, when installing the bracket 2, the two taller guide positioning posts 301 are used for priority guidance, which makes it easy to insert the other base positioning posts 302 into other vertical mounting holes, making the operation convenient.
[0024] A sliding base 4 is horizontally slidably connected to one side of the bracket 2 on the fixed base 1. The sliding base 4 is slidably connected to the sliding groove 103 provided on the fixed base 1 through the bottom slide bar 401. A fixed frame 5 is fixed on the sliding base 4. Multiple movable rods 6 corresponding to the mounting holes on the wing plate 202 of the bracket 2 are horizontally movably inserted into the fixed frame 5. The ends of the positioning post 3 and the movable rods 6 are all bullet-shaped.
[0025] A retainer 11 is also fixed on the sliding base 4. The retainer 11 is located on the side of the position indicator plate 7 away from the return spring 8. The movable rod 6 is horizontally inserted into the retainer 11 to further position the movable rod 6 and ensure its horizontality. The position indicator plate 7 is vertically fixed on the surface of the movable rod 6. If the tilt angle of the wing plate 202 on the base plate 201 is determined and meets the standard, the position indicator plates 7 corresponding to multiple movable rods 6 are located in the same vertical plane.
[0026] A limiting block 601 is fixed on the surface of the movable rod 6 near one end of the wing plate 202. The limiting block 601 is spherical, which facilitates tangential contact with the inclined wing plate 202. The limiting blocks 601 on multiple movable rods 6 corresponding to the same wing plate 202 are located in the same inclined plane parallel to the wing plate 202, which reflects the inclination angle of the wing plate 202.
[0027] A return spring 8 is installed between the movable rod 6 and the fixed frame 5. The return spring 8 is sleeved on the movable rod 6, and the two ends of the return spring 8 are fixedly connected to one side of the fixed frame 5 and the surface of the movable rod 6, respectively. A retaining ring 602 located between the retainer 11 and the position indicator plate 7 is fixed on the surface of the movable rod 6. By pulling the sliding base 4 to the left, the movable rod 6 can be pulled out from the mounting hole on the wing plate 202 through the retainer 11 and the retaining ring 602.
[0028] A control handle 9 is movably hinged to the fixed base 1. A fixed connecting rod 901 is fixed to the control handle 9. A guide groove 902 is provided on the fixed connecting rod 901. A hinge seat 10 with a hinge shaft inserted into the guide groove 902 is fixed on one side of the fixed frame 5. The control handle 9 is located on the left side and the positioning post 3 is located on the right side. When in use, the right hand is used to install the bracket 2 and the left hand is used to operate the control handle 9, which is convenient to use.
[0029] Working principle:
[0030] This fixture focuses on checking angles, not hole positions. The hole positions of bracket 2 are checked using a dedicated fixture. Bracket 2 is installed by aligning the vertical mounting holes on the base plate 201 with the positioning posts 3. The guide positioning posts 301, after positioning the two vertical mounting holes, naturally position the entire bracket 2. Multiple positioning posts 3 work together to position bracket 2, ensuring stable installation. With the right hand aligned with bracket 2, the left hand operates the control handle 9, moving the sliding base 4 to the right. This causes the movable rod 6 to move to the right and insert into the mounting hole on the wing plate 202 of bracket 2. The limiting block 601 restricts the insertion depth. If the wing plate 202 angle is standard, the position indicator plate 7 remains aligned and within the same vertical plane after movement, completing the angle test. If the wing plate 202 angle is incorrect, the insertion depth of the movable rod 6 at the corresponding position will differ, causing the corresponding position indicator plate 7 to shift to the left or right. The overall position indicator plate 7 will no longer be within the same vertical plane and will no longer be aligned, thus facilitating error detection by staff.
