Description

Technical Field

[0001] This utility model relates to the field of surface treatment technology for brackets, specifically a polishing device for bracket production. Background Technology

[0002] As an important mechanical component, stents are widely used in medical devices, automobile manufacturing, aerospace and other fields. Their surface quality directly affects the performance and service life of the product. Polishing, as a key process in stent production, is of great significance for improving surface smoothness, removing burrs and improving surface stress distribution.

[0003] Typically, the bracket to be polished is conveyed to the worktable of the polishing device via a conveyor, and secured with clamps to ensure stability during polishing. The polishing device is then started, and the bracket is polished by rubbing against the polishing disc as it moves forward. During polishing, the dust collection device on the worktable can absorb and clean the generated metal shavings and dust in real time, preventing impurities from causing secondary damage to the surface of the bracket. After polishing is completed, the clamps are released, and the bracket is moved out of the work area by the conveyor or robotic arm, completing the entire polishing process.

[0004] Existing polishing devices polish the outer surface of the bracket by reciprocating movement. The polishing range is limited to a local side of the bracket, and the bracket needs to be rotated many times to complete the overall polishing, which leads to low efficiency, cumbersome operation and increased time consumption. In addition, metal shavings and dust easily accumulate on the surface of the worktable, which rubs and pulls against the surface of the bracket, causing scratches, abrasions and other defects, affecting the appearance quality of the bracket. Therefore, an innovative polishing device for bracket production is proposed to address the above problems. Utility Model Content

[0022] 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 scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] like Figure 1 As shown in the embodiment of this utility model, a polishing device for bracket production includes a workbench 1; a fixed base 11 is fixedly connected to one end of the workbench 1; two sets of baffles 15 are fixedly connected to the middle of the surface of the fixed base 11; screws 14 are threadedly connected to the middle of the baffles 15; rubber pads 16 are fixedly connected to the bottom of the screws 14; two sets of rubber wheels 13 are rotatably connected inside the fixed base 11 and arranged in a straight line; a second fixed base 12 is fixedly connected above the workbench 1, similar to the fixed base 11; a rotating shaft 19 is fixedly connected above the workbench 1; two sets of rotating shafts 19 are provided; the rotating shaft 19 is fixedly connected to the fixed base 11. A grinding wheel 17 is rotatably connected above the rotating shaft 19 at the middle of the fixed base 12; a rotating shaft 110 is fixed above the worktable 1; the rotating shaft 110 is fixed between the rotating shaft 19 and the fixed base 11; two sets of rotating shafts 110 are provided; a grinding wheel 18 is rotatably connected to the middle of the rotating shaft 110; two sets of grinding wheels 18 are provided in the middle of the rotating shaft 110; the grinding wheel 17 and the grinding wheel 18 are detachable, and grinding wheels of different sizes can be replaced; during operation, first measure the width of the square bracket, replace it with the appropriate grinding wheel 17 and the grinding wheel 18, and then screw the baffle 15 above the fixed base 11 into place. With the screws engaged, turn screw 14 outwards by a distance slightly larger than the width of the bracket measured by rubber pad 16, ensuring the square bracket is prevented from deviating. The same applies to the two sets of screws 14 above the second mounting base 12. Start grinding wheels 17 and 18, place the square bracket above the first mounting base 11, and apply a pushing force to the square bracket. This causes rubber wheel 13 to rotate and pass between the two sets of baffles 15. Polishing begins on the top and bottom sides of the square bracket from the center of grinding wheel 18, and on the left and right sides from the center of grinding wheel 17. The polished square bracket then moves forward via rubber wheel 13 above the second mounting base 12, passing through the two sets of baffles. 15. The rubber wheel 13 above the fixed base 11 facilitates the forward movement of the square bracket, avoiding direct contact between the square bracket and the fixed base 11, which could cause scratches on the surface of the square bracket due to friction. The multiple sets of screws 14 are adjustable and can adapt to square brackets of different sizes. The rotation distance of the screws 14 can prevent the square bracket from shifting during forward movement. The rubber pad 16 at the bottom of the screws 14 can reduce scratches on the square bracket during movement. The square bracket passes through the high-speed rotating abrasive wheel 17 and abrasive wheel 28 to polish all four sides simultaneously, avoiding repeated polishing. The screw 14 above the fixed base 2 is used to stabilize the forward linear movement of the polished square bracket.

[0025] like Figure 2As shown, a protective cover 5 is fixedly attached above the workbench 1; a cooling cover 2 is fixedly attached below the top of the protective cover 5; the cooling cover 2 is directly above the workbench 1; a rotating shaft 21 is provided in the middle of the cooling cover 2 and is rotatably connected to the cooling cover 2; multiple sets of fan blades 22 are fixedly attached to the top of the rotating shaft 21 and are distributed in a circle around the fan blades 22; during operation, when the high-speed rotating abrasive wheel 17 and abrasive wheel 28 polish the square bracket, high temperature and polishing residue will be generated. When the cooling cover 2 is activated, the airflow is directed towards the contact part between the polishing wheel and the workpiece. When the abrasive wheel 17 and abrasive wheel 2 18 rotate at high speed, the airflow generated by the cooling cover 2 can carry away some of the heat, preventing the square bracket from being affected by overheating or damaged during the polishing process. The airflow generated by the cooling cover 2 can also blow away some of the residue remaining on the surface of the polished square bracket.

[0026] like Figure 3 As shown, a first telescopic plate 3 is fixedly connected to the top of the workbench 1 near the fixed base 12; a second telescopic plate 31 is slidably connected to the side of the first telescopic plate 3; a handle 32 is fixedly connected to the side of the second telescopic plate 31; during operation, after the square bracket is polished, because its length exceeds the workbench 1, the handle 32 can be pulled to extend the length of the first telescopic plate 3, and the square bracket can be placed on top to provide additional support and prevent bending due to the square bracket being too long.

[0027] like Figure 3 As shown, a cleaning module 4 is provided above the workbench 1; the first telescopic plate 3 is fixed to the middle of the cleaning module 4; a cleaning brush 41 is provided inside the cleaning module 4, and the cleaning brush 41 is detachable and replaceable; during operation, the polished square bracket can move forward through the middle of the cleaning module 4 to contact the surface of the cleaning brush 41, removing polishing residue, dust and other impurities remaining on the surface of the square bracket, ensuring that the bracket surface is clean. The cleaning brush 41 is detachable and replaceable, which is convenient for replacement or cleaning after long-term use, thus extending its service life.

[0028] like Figure 4 As shown, a protective cover 5 is fixedly attached above the workbench 1. The protective cover 5 is located in the middle of the fixed base 11 and the fixed base 12. Two sets of handrails 51 are fixedly attached to one side of the protective cover 5. The handrails 51 on one side of the protective cover 5 are detachable. During operation, the high-speed rotating grinding wheel 17 and grinding wheel 28 will generate a large amount of polishing debris when polishing the square bracket. In order to prevent the debris from splashing, the device is equipped with a protective cover 5, which can effectively block the debris generated during the polishing process from spreading to the surroundings and keep the working environment clean. One side of the protective cover 5 can be removed through the handrails 51, which can facilitate the cleaning of the debris that has accumulated inside the protective cover 5 for a long time, ensuring the cleanliness of the inside of the device and avoiding the accumulation of debris from affecting the polishing effect and the normal operation of the equipment.

[0029] like Figure 5 As shown, a protective cover 5 is provided above the workbench 1; a light holder 61 and a light holder 62 are fixedly connected inside the protective cover 5; a light rod 6 is fixedly connected in the middle of the light holder 61 and the light holder 62; during operation, the light rod 6 installed inside the protective cover 5 can illuminate the polished parts, providing sufficient light to clearly observe the polishing process and the real-time condition of the workpiece surface, ensuring no shadow interference in the working area, improving polishing accuracy and quality. The light rod 6 has excellent waterproof and dustproof functions, and can operate stably in high dust and high humidity environments, avoiding dust pollution or water vapor corrosion due to long-term use, thereby effectively preventing the reduction of lighting brightness and extending its service life.

[0030] Working principle: First, measure the width of the square bracket. Replace with appropriate grinding wheels 17 and 18. Then, through the threaded connection, rotate screw 14 outwards on the baffle 15 above the fixing seat 11. The rotation distance should be slightly larger than the bracket width measured by the rubber pad 16, so that it can prevent the square bracket from deviating. Repeat the same process for the two sets of screws 14 above the fixing seat 12. Start grinding wheels 17 and 18, place the square bracket on the fixing seat 11, and apply a pushing force to the square bracket. This will cause the rubber wheels to... 13 rotates and passes between the two sets of baffles 15, polishing the upper and lower sides of the square bracket starting from the middle of the second grinding wheel 18, and polishing the left and right sides of the square bracket starting from the middle of the first grinding wheel 17. After polishing, the square bracket moves forward through the rubber wheel 13 above the fixed seat 2 12, passing through the two sets of baffles 15. When the high-speed rotating first grinding wheel 17 and second grinding wheel 18 polish the square bracket, high temperature and polishing residue are generated. The air cooling cover 2 is activated and the airflow is directed towards the contact area between the polishing wheel and the workpiece. When the first grinding wheel... When grinding wheels 17 and 18 rotate at high speed, the airflow generated by the air-cooled cover 2 can carry away some of the heat. After polishing, the square bracket, being longer than the worktable 1, can have its second telescopic plate 31 extended by pulling the handle 32 to extend the length of the first telescopic plate 3, placing the square bracket on top to provide additional support. After polishing, the square bracket can move forward through the middle of the cleaning module 4 to contact the surface of the cleaning brush 41, removing polishing residue, dust, and other impurities remaining on the surface of the square bracket, ensuring the bracket surface is clean. When the high-speed rotating grinding wheels 17 and 18 polish the square bracket, they generate a large amount of polishing debris. To prevent debris from splashing, the device is equipped with a protective cover 5, which can effectively block the debris generated during the polishing process from spreading to the surroundings, keeping the working environment clean. One side of the protective cover 5 can be removed through the handle 51, making it easy to clean the debris that has accumulated inside the protective cover 5 for a long time. The light bar 6 installed inside the protective cover 5 can illuminate the polished parts, providing sufficient light.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
