Description

Technical Field

[0001] This invention relates to the field of medical device processing technology, and in particular to a sandblasting system and method. Background Technology

[0002] Most medical device products require high-temperature shaping. In order to eliminate internal stress and improve overall performance, the surface of medical device products needs to be sandblasted to remove oxidation and polish the product surface.

[0003] In the prior art, sandblasting equipment includes a nozzle and a support. The nozzle can be connected to the sandblasting structure to perform sandblasting at a specified speed. The support is installed inside the support along the axial direction of the bracket. One end of the support is fixedly connected to a pulley. During sandblasting, a drive motor drives the pulley to rotate via a belt. The pulley then drives the bracket to rotate during the sandblasting process via the support, thereby completing the sandblasting process.

[0004] However, during the sandblasting process, the torque generated by the drive motor is transmitted to the support through the belt and the support, and the support is difficult to limit the support in the axial direction. When the support is impacted during the sandblasting process, it is easy for the support to move axially, which causes the torque of the support to deviate from the torque of the drive motor. As a result, the speed of the support is prone to be uneven, which leads to a poor sandblasting effect. Summary of the Invention

[0005] The purpose of this invention is to provide a sandblasting system and method that solves the problem in the prior art where the support is prone to axial movement during the sandblasting process, which leads to uneven rotation speed and a deterioration in the sandblasting effect.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] In a first aspect, this application provides a sandblasting system comprising:

[0008] A sandblasting device having a nozzle that can slide back and forth and is used for sandblasting;

[0009] A rotating shaft is positioned opposite to the nozzle, and the support to be sandblasted is fitted onto the rotating shaft;

[0010] Multiple sets of support components are distributed at intervals along the circumference of the rotating shaft. The support components pass through the mesh of the bracket and are snapped and fixed to the rotating shaft.

[0011] A driving component is connected to the rotating shaft to drive the rotating shaft to rotate the bracket.

[0012] Optionally, the support component includes:

[0013] The first support rod passes through the mesh of the bracket along the first direction and is engaged with the rotating shaft. The side wall of the first support rod abuts against the mesh wall of the bracket.

[0014] The second support rod passes through the mesh of the bracket along the second direction and is engaged with the rotating shaft. The side wall of the second support rod abuts against the mesh wall of the bracket.

[0015] Optionally, the angle between the first direction and the second direction is β, where 30°≤β≤150°.

[0016] Optionally, the diameter of the support is D, and the distance between the mesh through which the first support rod passes and the mesh through which the second support rod passes is L, where L = tan(β / 2)*D.

[0017] Optionally, the rotating shaft has a through hole corresponding to the support component, and the support component is inserted into the through hole.

[0018] Optionally, a connecting sleeve is provided at the position of the rotating shaft corresponding to the support component. The connecting sleeve is elastic and has a plug hole for the support component to be inserted.

[0019] Optionally, the angle between the direction of the spraying head and the axial direction of the rotating shaft is between 30° and 90°.

[0020] Optionally, the sandblasting device includes:

[0021] An adjustment disc is provided, and the nozzle is disposed on the adjustment disc, which is used to adjust the orientation of the nozzle;

[0022] A drive component is connected to the adjustment disc to drive the adjustment disc to move the nozzle back and forth.

[0023] Optionally, multiple nozzles are spaced apart.

[0024] Secondly, sandblasting methods include:

[0025] The bracket is fitted onto the rotating shaft, and multiple support components are inserted at intervals on the bracket so that the support components are snapped and fixed to the rotating shaft;

[0026] The drive unit is activated, and the drive unit drives the rotating shaft to rotate the bracket through the support assembly;

[0027] Start the sandblasting device, control the nozzle to slide back and forth relative to the bracket, and perform multiple sandblasting processes on the bracket during the sliding process.

[0028] The beneficial effects of this invention are:

[0029] Firstly, during sandblasting, a bracket is fitted onto a rotating shaft, with multiple sets of support components spaced apart on the bracket. The support components are locked to the rotating shaft, creating a rigid limit between the bracket and the shaft. This effectively restricts the axial movement of the bracket. When the drive unit rotates the shaft, the shaft, through the support components, drives the bracket to rotate. During this rotation, the sandblasting nozzles blast the bracket. When the bracket is impacted during sandblasting, the fixed support components prevent axial displacement, ensuring the bracket does not shift along its axis. Therefore, this sandblasting system ensures no axial displacement of the bracket on the rotating shaft, allowing it to rotate synchronously with the shaft. This ensures the torque of the bracket matches the torque output by the drive unit, reducing the possibility of uneven bracket rotation. Consequently, the bracket receives uniform impact from the sand, effectively improving the sandblasting effect.

[0030] Secondly, through the above steps, the bracket can be effectively limited during the sandblasting process, ensuring that the bracket will not shift axially, thereby ensuring that the rotation speed of the bracket remains stable and effectively improving the sandblasting effect on the bracket.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0052] This application discloses a sandblasting system and method.

[0053] Example 1:

[0054] Reference Figure 1 The sandblasting system includes a sandblasting device 1, a rotating shaft 2, a drive unit 3, and multiple sets of support components 4. The sandblasting device 1 has a nozzle 11 that can reciprocate and slide for sandblasting; the rotating shaft 2 is arranged opposite to the nozzle 11, and the support 5 to be sandblasted is sleeved on the rotating shaft 2; multiple sets of support components 4 are distributed circumferentially along the rotating shaft 2, and the support components 4 pass through the mesh of the support 5 and are snapped and fixed to the rotating shaft 2; the drive unit 3 is connected to the rotating shaft 2 to drive the rotating shaft 2 to rotate the support 5.

[0055] Specifically, the sandblasting device 1 includes a suspension bracket 12, which is elongated. A drive assembly 121 is slidably connected to the middle of the suspension bracket 12. The drive assembly 121 can automatically move back and forth on the suspension bracket 12. A suspension frame 13 is fixedly connected to the drive assembly 121. Multiple nozzles 11 can be spaced out on the suspension frame 13. Each nozzle 11 is connected to the suspension frame 13 via an adjustment disc 131. The adjustment disc 131 can adjust the orientation of the nozzle 11 so that the spraying angle of the nozzle 11 can be flexibly adjusted. In this embodiment, the angle between the direction of sandblasting by the nozzle 11 and the axial direction of the rotating shaft 2 is between 30° and 90°, so as to ensure that the impact force on the support 5 and other structures is minimized during the sandblasting operation while ensuring smooth sandblasting.

[0056] A rotating shaft 2 is installed below the nozzle 11. One end of the rotating shaft 2 is connected to the output end of the drive component 3. The drive component 3 can be a motor, which is directly connected to one end of the rotating shaft 2 via a coupling, or it can be connected to one end of the rotating shaft 2 via a belt drive or chain drive, etc., as long as it can smoothly drive the rotating shaft 2 to rotate. The bracket 5 is a long cylindrical shape with a grid pattern, which is sleeved on the rotating shaft 2. Multiple sets of support components 4 are distributed at intervals along the axial direction of the bracket 5. The support components 4 pass through the bracket 5 and are locked to the rotating shaft 2. The support components 4 and the bracket 5 can be pressed against each other to form a lock. The support components 4 and the rotating shaft 2 can be locked by inserting them together to achieve an interference fit or a tapered fit, so that the bracket 5 and the rotating shaft 2 are rigidly limited. For example, the diameter of the through hole of the rotating shaft 2 is slightly smaller than the outer diameter of the insertion part of the support component 4 to form an interference fit. The tapered fit can be achieved by setting the through hole of the rotating shaft 2 as a tapered hole or setting the insertion part of the support component 4 as a tapered shape.

[0057] During sandblasting, the bracket 5 is fitted onto the rotating shaft 2, and multiple sets of support components 4 are arranged at intervals on the bracket 5. The support components 4 are fixed to the rotating shaft 2 by snapping together, so that a hard limit is formed between the bracket 5 and the rotating shaft 2. This fixes the bracket 5 on the rotating shaft 2 and effectively restricts the axial movement of the bracket 5. When the driving component 3 drives the rotating shaft 2 to rotate, the rotating shaft 2 can drive the bracket 5 to rotate through the support components 4. During the rotation of the bracket 5, the nozzle 11 of the sandblasting device 1 can perform sandblasting on the bracket 5. During the sandblasting process, when the bracket 5 is impacted, it will not move because the support components 4 are snapped together with the rotating shaft 2. This effectively limits the axial movement of the bracket 5 and ensures that the bracket 5 will not deviate along its axial direction. Therefore, when the sandblasting system sandblasts the bracket 5, it can ensure that the bracket 5 does not undergo axial displacement on the rotating shaft 2, so that the bracket 5 can rotate synchronously with the rotating shaft 2, ensuring that the torque of the bracket 5 matches the torque output by the drive component 3, reducing the possibility of uneven rotation speed of the bracket 5, so that the bracket 5 can be evenly impacted by the sand and gravel, thereby effectively improving the sandblasting effect.

[0058] Reference Figures 2 to 5 Optionally, the support assembly 4 includes a first support rod 41 and a second support rod 42. The first support rod 41 passes through the mesh of the bracket 5 along a first direction and is engaged with the rotating shaft 2, with the side wall of the first support rod 41 abutting against the mesh wall of the bracket 5; the second support rod 42 passes through the mesh of the bracket 5 along a second direction and is engaged with the rotating shaft 2, with the side wall of the second support rod 42 abutting against the mesh wall of the bracket 5.

[0059] Specifically, the mesh of the bracket 5 includes two first mesh holes 51 and two second mesh holes 52. The two first mesh holes 51 correspond to each other when the bracket 5 is cylindrical, allowing the first support rod 41 to pass through. The side wall of the first support rod 41 abuts against the hole wall of the first mesh hole 51 to lock the first support rod 41. A through hole 21 is provided through the rotating shaft 2, through which the first support rod 41 passes and exits from the other first mesh hole 51, thereby achieving the snap-fit ​​fixation of the first support rod 41 and the rotating shaft 2. The second support rods 42 are all inserted in a different direction than the first support rods 41, which will not be described in detail here. The first support rods 41 and the second support rods 42 are spaced a certain distance apart along the circumference of the bracket 5.

[0060] By setting the first support rod 41 and the second support rod 42, the bracket 5 can be limited in at least two directions, thereby ensuring that the connection strength between the bracket 5 and the rotating shaft 2 is good. Then, the rotating shaft 2 can drive the first support rod 41 and the second support rod 42 to rotate synchronously during the rotation process, and the first support rod 41 and the second support rod 42 can drive the bracket 5 to rotate synchronously.

[0061] Reference Figures 6 to 9Optionally, the angle between the first direction and the second direction is β, 30°≤β≤150°, the diameter of the support 5 is D, and the distance between the mesh through which the first support rod 41 passes and the mesh through which the second support rod 42 passes is L, where L=tan(β / 2)*D.

[0062] Specifically, the diameter of the bracket 5 when fully expanded is D. When the diameter D changes, the relative positions of the first mesh 51 and the second mesh 52 also change. Consequently, the included angle formed by the first support rod 41 and the second support rod 42 after insertion also varies. The β angle is limited to the range of 30° to 150° to allow the first support rod 41 and the second support rod 42 to intersect, thus effectively limiting and fixing brackets 5 of various sizes. Furthermore, when the diameter D of the bracket 5 changes, according to L = tan(β / 2) * D, the distance L between the first support rod 41 and the second support rod 42 along the axial direction of the bracket 5 is adjusted accordingly. This allows the limiting position between the support assembly 4 and the bracket 5 to be appropriately adjusted according to the size of the bracket 5, ensuring effective limiting of the bracket 5. The number of support assemblies 4 can also be adjusted according to the size of the bracket 5. In this embodiment, only one set of support assemblies 4 is provided at each end of the bracket 5.

[0063] Reference Figures 10 to 12 Optionally, when the support 5 is in the coiled state, and its diameter is D when it is fully expanded, the arc length between the mesh through which the first support rod 41 passes and the mesh through which the second support rod 42 passes can be set as H, where H = (β / 180) * πD. In this case, H is directly proportional to the diameter D; that is, the larger the diameter of the support 5, the larger H is, and the larger the arc length of the first support rod 41 and the second support rod 42 along the circumferential direction of the support 5. Therefore, the arc lengths of the first support rod 41 and the second support rod 42 can be appropriately adjusted according to the dimensions of the support 5, thereby ensuring that the support 5 maintains a high connection strength with the rotating shaft 2. The calculation of the spacing L or the arc length H based on the diameter D of the support 5 has the same effect; either method can be chosen for calculation based on the actual situation during the design process.

[0064] The sandblasting method includes:

[0065] Reference Figure 13 Step S1: Fit the bracket 5 onto the rotating shaft 2, and insert multiple support components 4 at intervals on the bracket 5 so that the support components 4 are snapped and fixed to the rotating shaft 2;

[0066] Step S2: Start the operation of the drive component 3. The drive component 3 drives the rotating shaft 2 to rotate the bracket 5 through the support component 4.

[0067] Step S3: Start the sandblasting device 1, control the nozzle 11 to slide back and forth relative to the bracket 5 and perform multiple sandblasting processes on the bracket 5 during the sliding process.

[0068] Specifically, multiple brackets 5 can be simultaneously mounted on the rotating shaft 2, and each bracket 5 can be equipped with multiple support components 4. The support components 4 and the rotating shaft 2 can be fixed with an interference fit or a tapered fit to secure each bracket 5 to the rotating shaft 2. The driving component 3 can drive the rotating shaft 2 and the brackets 5 to rotate at a speed w, which can range from 100 rpm to 600 rpm. Before sandblasting begins, the spray direction of the nozzle 11 located on the right side of the bracket 5 intersects with the rotating shaft 2 at a distance of 2 cm to 5 cm in front of the head end of the bracket 5. After sandblasting begins, the nozzle 11 moves at a constant speed v, which can be between 0.05 m / min and 0.3 m / min. When the spray direction of the nozzle 11 located on the left side of the bracket 5 intersects with the rotating shaft 2 at a distance of 2 cm to 5 cm from the tail end of the bracket 5, the nozzle 11 begins to move in the opposite direction and returns to its initial position, thus ending a single sandblasting session. Generally, the above sandblasting process is repeated 2 to 6 times.

[0069] Through the above steps S1 to S3, the bracket 5 can be effectively limited during the sandblasting process, ensuring that the bracket 5 will not deviate along the axial direction, thereby ensuring that the rotation speed of the bracket 5 remains stable and effectively improving the sandblasting effect of the bracket 5.

[0070] Example 2

[0071] Based on Embodiment 1, the difference between this embodiment and Embodiment 1 lies in the connection method between the rotating shaft 2 and the support component 4.

[0072] Reference Figures 14 to 15 Optionally, a connecting sleeve 6 is provided at the position of the rotating shaft 2 corresponding to the support component 4. The connecting sleeve 6 is elastic and has a plug hole for the support component 4 to be inserted.

[0073] Specifically, a connecting sleeve 6 is fixedly installed on the rotating shaft 2. The fixing method can be non-removable, such as welding or bonding, or removable, such as screwing, snap-fitting or bolting. Taking bolting as an example, a through threaded hole is opened on the connecting sleeve 6, and the bolt is screwed into the threaded hole. The bolt can extend into the connecting sleeve 6 to form a tight fit with the rotating shaft 2, thereby realizing the fixed connection between the connecting sleeve 6 and the rotating shaft 2.

[0074] The connecting sleeve 6 is made of a material with a certain elasticity, such as hard rubber. An insertion hole is provided on the outer wall of the connecting sleeve 6. The first support rod 41 can be inserted into the insertion hole and pass through the through hole 21 on the rotating shaft 2 and out of the insertion hole on the other side, and then pass through the first mesh 51 and out of the bracket 5. Similarly, the second support rod 42 is also set through the bracket 5. In another embodiment, the first support rod 41 is provided with one connecting sleeve 6, and the second support rod 42 is provided with another connecting sleeve 6. The specific arrangement can be adjusted according to the actual distance between the first support rod 41 and the second support rod 42. This application does not limit this.

[0075] By setting a flexible connecting sleeve 6, the insertion hole can deform to a certain extent when the support component 4 is inserted into it, thus facilitating the insertion of the first support rod 41 and the second support rod 42 of the support component 4 at different angles. It should be understood that after setting the connecting sleeve 6, it is not necessary to drill a hole separately on the rotating shaft 2. In this case, neither the first support rod 41 nor the second support rod 42 passes through the rotating shaft 2. Instead, insertion holes are set on opposite sides of the connecting sleeve 6. The first support rod 41 is divided into two sections. One section passes through a first mesh 51 and is inserted into the insertion hole, while the other end is inserted through another first mesh 51 and plugged into the corresponding insertion hole. The second support rod 42 is set in a similar manner. This eliminates the need to drill a hole on the rotating shaft 2, thus ensuring that the strength of the rotating shaft 2 meets the requirements.

[0076] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
