Description

Technical Field

[0001] The present application relates to the technical field of medical device production, and more particularly, to a stent polishing tooling and a polishing device. Background Art

[0002] When the current stent is suspended and polished on a common L-shaped hanger, since the stent is in a static state, the polishing current will pass through the inner surface of the stent for a long time, especially at the local position where the stent is lapped with the hanger, and the current passes through all the time, which is not conducive to obtaining a relatively uniform polishing effect. In severe cases, problems such as orange peel are likely to occur, affecting the surface gloss of the stent.

[0003] On the other hand, when the stent is suspended on an L-shaped or other-shaped hanger, with the external stirring of the polishing liquid, it is easy to cause the stent to shake on the hanger, resulting in uneven beam widths of the polished stent, affecting the structural performance of the stent.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, rather than all of them. Usually, the components of the embodiments of this application described and shown in the accompanying drawings here can be arranged and designed in various different configurations.

[0040] In the description of this application, it should be noted that the orientation or positional relationship indicated by terms such as "inside", "outside", etc. is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this application is usually placed during use.

In addition, terms such as "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0041] In the description of this application, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific situations.

[0042] See Figure 1 and in combination with Figures 2 - 6 In the bracket polishing tooling of this application, mainly through the horizontal rotation of the rotating frame 2 in the polishing liquid, it drives the bracket to rotate during the polishing process. Further, while rotating, the bracket rolls around the bracket rod 21, maximizing the improvement of the state of the bracket during the polishing process.

[0043] By connecting the rotating shaft 3 to the rotating frame 2 and arranging a driving assembly on the polishing tank 1, and combining the driving connection between the driving assembly and the rotating shaft 3 through the transmission assembly 5, the rotating frame 2 can be driven by the driving assembly to rotate horizontally around the rotating shaft 3 as the axis.

[0044] The support rod 21 arranged on the rotating frame 2 can be sleeved with a support, so that the support can be placed on the rotating frame 2, and then rotate circumferentially following the horizontal rotation of the rotating frame 2.

[0045] Specifically under the action of the rotating shaft 3, the rotating frame 2 drives the support to rotate horizontally in a state of being completely immersed in the polishing liquid. During its rotation, a certain centrifugal force can be formed on the polishing liquid, further causing the support movably sleeved on the support rod 21 to roll around the support rod 21 to change the polishing state of the support on the existing L-shaped hanger.

[0046] The rotating frame 2 can form the revolution of the support around the rotating shaft 3, and at the same time can form the revolution of the support around the support rod 21, and also includes its own rotation. Through the combination of different rotation states, the static state of the existing support can be changed to dynamic rotation and rolling, so that the inner and outer surfaces of the support can be polished relatively evenly, improving the polishing effect of the overall surface.

[0047] The revolution of the support around the support rod 21 and the combination of its own rotation can avoid the irregular shaking of the support, and can make different linear parts on the inner surface of the support evenly in line contact with the support rod 21 to avoid the occurrence of irregular collisions of the support, resulting in uneven beam width and thickness.

[0048] In order to form a rotating relationship, the rotating shaft 3 passes through the rotating frame 2. Specifically, under the counterweight effect, the rotating frame 2 is located at the bottom of the rotating shaft 3, and the bottom end of the rotating shaft 3 is rotatably installed on the bottom of the polishing tank 1. Through this setting method, the rotating shaft 3 can rotate and be positioned inside the polishing tank 1, and at the same time can drive the rotating frame 2 to rotate synchronously with the rotating shaft 3.

[0049] The driving assembly includes a driving motor 4. A motor bracket 11 for installing the driving motor 4 is arranged on the outer side wall of the polishing tank 1, and the output shaft of the driving motor 4 is vertically upward.

[0050] A driving runner 41 is connected to the output shaft, and a transmission runner 31 is installed on the rotating shaft 3. Further, the driving runner 41 is installed at the top end of the output shaft, the transmission runner 31 is installed at the top end of the rotating shaft 3, and the transmission assembly 5 is arranged between the driving runner 41 and the transmission runner 31.

[0051] By installing a transmission assembly 5 between the driving runner 41 and the transmission runner 31, a transmission connection can be formed, enabling the driving motor 4 to drive the rotating shaft 3 and the rotating frame 2 to rotate at a constant speed.

[0052] The driving runner 41, the transmission runner 31, and the transmission assembly 5 include different forms. In one specific setting form, both the driving runner 41 and the transmission runner 31 can be pulley wheels, and the transmission assembly 5 includes a transmission belt disposed between the driving pulley wheel and the transmission pulley wheel.

[0053] In another specific setting form, both the driving runner 41 and the transmission runner 31 can be sprocket wheels, and the transmission assembly 5 includes a transmission chain disposed between the driving sprocket wheel and the transmission sprocket wheel.

[0054] In another preferred setting form, both the driving runner 41 and the transmission runner 31 can be gear wheels, and the transmission assembly 5 includes a transmission rack disposed between the driving gear wheel and the transmission gear wheel.

[0055] To facilitate the disassembly of the rotating shaft 3 and the rotating frame 2, both the driving runner 41 and the transmission runner 31 can be pulley wheels, and the transmission assembly 5 includes a transmission belt disposed between the driving pulley wheel and the transmission pulley wheel. By turning the transmission belt outwards, the transmission pulley wheel, the rotating shaft 3, and the rotating frame 2 can be disengaged from the transmission belt, and the rotating frame 2 can be fished out of the polishing liquid, thus facilitating the operation of placing and removing the bracket.

[0056] Furthermore, there are two driving motors 4 in the present utility model. The two driving motors 4 are respectively disposed on both sides of the polishing tank 1. Driving pulley wheels are provided on the output shafts of the driving motors 4, and the transmission belt is wound around between the two driving pulley wheels. When the driving motors 4 are running synchronously, the transmission belt can be synchronously wound and coiled between the two driving pulley wheels, thereby driving the transmission pulley wheel and the rotating shaft 3 to rotate.

[0057] There are two sets of the rotating shaft 3, the transmission pulley wheel, and the rotating frame 2. The two sets of transmission pulley wheels are respectively clamped between the transmission belts, which can play a certain limiting role. It should be noted that in order to prevent the top of the rotating shaft 3 from shifting, a movable cross plate can be provided at the top of the polishing tank 1. By opening a through hole for the rotating shaft 3 to pass through on the movable cross plate and lapping the movable cross plate on the two side edges of the polishing tank 1, the limiting effect on the rotating shaft 3 can be achieved.

[0058] The rotating frame 2 includes a wheel frame bracket. The wheel frame bracket includes a top wheel frame 22 and a bottom wheel frame 23. The support rod 21 is vertically installed on the bottom wheel frame 23. A support through hole 24 for the support to pass through is provided on the top wheel frame 22. Preferably, the height of the support rod 21 is less than the distance between the top wheel frame 22 and the bottom wheel frame 23, which is conducive to the through connection and installation of the support on the support rod 21.

[0059] Meanwhile, for the convenience of taking and placing the bracket, the positions of the bracket rod 21 and the bracket through-hole 24 are vertically opposite and concentrically arranged.

[0060] Furthermore, the diameter of the bracket through-hole 24 is larger than the outer diameter of the bracket rod 21, and the diameter of the bracket is smaller than the diameter of the bracket through-hole 24, which can make it more convenient to take and place the bracket on the bracket rod 21.

[0061] From the perspective of the structure of the rotating frame 2, a support vertical beam 25 is also arranged between the top wheel frame 22 and the bottom wheel frame 23, and the overall structure of the rotating frame 2 can be formed through the support vertical beam 25.

[0062] In order to reduce the influence of the support vertical beam 25 on the taking and placing of the bracket, and to avoid the bracket colliding with the support vertical beam 25 during the polishing process, which affects the polishing effect of the outer surface, the support vertical beam 25 is arranged at the radial edge of the wheel frame bracket.

[0063] The bracket rod 21 is arranged on the radial inner side of the support vertical beam 25 and includes multiple channels arranged in different radial directions. The multiple bracket rods 21 are arranged in a divergent manner. Furthermore, different bracket rods 21 can be arranged in multiple circles in the circumferential direction of the rotating frame 2, so as to form a divergent arrangement form in the three-dimensional space.

[0064] From the perspective of the cooperation between the rotating shaft 3 and the rotating frame 2, shaft holes 26 for the rotating shaft 3 to pass through are arranged at the centers of both the top wheel frame 22 and the bottom wheel frame 23, and the diameters of the shaft holes 26 are the same.

[0065] In order to enable the rotating frame 2 to be located at the bottom of the rotating shaft 3 with a counterweight effect and not to separate from the rotating shaft 3, a limiting boss 27 is arranged at the bottom of the rotating shaft 3, and the outer diameter of the limiting boss 27 is larger than the diameter of the shaft hole 26.

[0066] Meanwhile, based on the fact that the rotating shaft 3 drives the rotating frame 2 to rotate synchronously, in order to ensure the reliability of the driving cooperation, positioning fins are arranged on the top wall of the limiting boss 27, and positioning sunk grooves are arranged on the bottom wall of the bottom wheel frame 23. Through the cooperation and clamping of the positioning fins and the positioning sunk grooves, the rotating frame 2 and the rotating shaft 3 can be clamped in a form of movable cooperation, so as to ensure the reliability of the rotation of the rotating frame 2 following the rotating shaft 3.

[0067] The positioning sunk grooves are arranged on both sides of the shaft hole 26 and communicate with the shaft hole 26, which can reduce the difficulty in the clamping cooperation process. Furthermore, the length of the positioning sunk grooves can be slightly larger than the length of the positioning fins.

[0068] The bottom end of the rotating shaft 3 described above is rotatably installed at the bottom of the polishing tank 1. A positioning boss 28 is provided at the bottom of the limiting boss 27, and a rotating shaft groove 12 is provided on the bottom wall of the polishing tank 1. By making the positioning boss 28 and the rotating shaft groove 12 in clearance fit, the bottom end of the rotating shaft 3 can be rotatably fitted in the rotating shaft groove 12. Combining with the limiting of the rotating shaft 3 by the movable cross plate, especially the lower part of the driving pulley on the rotating shaft 3, can ensure that the rotating shaft 3 rotates in a vertical state, enhancing the reliability during operation.

[0069] The bracket polishing tooling in the present utility model can improve the state of the bracket in the polishing liquid, changing from static to dynamic, stabilizing the rotation and rolling speed of the bracket in the polishing liquid, maintaining a uniform speed. The rotating shaft 3 and the rotating frame 2 are made of corrosion-resistant metals such as pure titanium and platinum, which is convenient for carrying the bracket to obtain current. With the power provided by the driving motor 4, the rotating frame 2 can rotate uniformly, driving the bracket to rotate uniformly in the polishing liquid, improving the polishing effect of the inner and outer surfaces of the bracket. The driving pulley and the rotating pulley can be provided with external teeth, and the inner side of the transmission belt can be provided with meshing teeth, thereby improving the transmission efficiency of the transmission belt and increasing the qualified rate of bracket polishing.

[0070] The set number of the rotating frames 2 is limited by the size of the polishing tank 1 and can be specifically set according to the actual situation. The installation position and angle of the driving motor 4 can be adjusted according to the actual situation, and the transmission mode of the driving motor 4 is adjustable.

[0071] Driving the bracket to roll through external power has a better polishing effect compared to the static state of the bracket. It is applicable to brackets of different lengths. The size, number, and position of the bracket rods 21 on the rotating frame 2 can be adjusted according to the length, diameter, and structure of the bracket. The size, position, and number of the driving wheels 31 on the rotating shaft 3 can be adjusted and changed according to the transmission mode.

[0072] The present utility model also provides a polishing device, including a polishing machine and the above-mentioned bracket polishing tooling, which can improve the polishing effect of the bracket on the polishing device.

[0073] It should be noted that, without conflict, the features in the embodiments of the present application can be combined with each other.

[0074] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
