Description

Technical Field

[0001] This utility model relates to the field of polishing wheel technology, specifically to a wheel assembly for polishing metal surfaces. Background Technology

[0002] A grinding wheel, also known as a bonded abrasive, is a type of abrasive tool in which ordinary abrasive grains are bonded together with a bonding agent to form a specific shape (mostly circular with a central through-hole) and possess a certain strength. It generally consists of abrasive grains, a bonding agent, and pores; these three parts are often referred to as the three essential elements of a bonded abrasive tool. Based on the type of bonding agent used, common types include ceramic (bonded) grinding wheels, resin (bonded) grinding wheels, and rubber (bonded) grinding wheels.

[0003] Publication number CN221849783U discloses a special polishing wheel for hard-to-grind metals. This patent uses an electric telescopic rod to drive the polishing wheel to automatically grind the metal on the table. During grinding, the rotation of a third gear drives the metal on the table to move back and forth, allowing the metal surface to be ground multiple times, thus improving the grinding effect on hard-to-grind metals. However, this patent still has the following problems in actual use:

[0004] The polishing wheel, driven by an electric telescopic rod, can automatically grind the metal on the platform. However, in actual use, when the surface of the metal component is relatively rough and has obvious machining marks or burrs, it is necessary to first use a low-grit (e.g., 40-80 grit) wheel for rough grinding. As the polishing process progresses, in order to gradually reduce the surface roughness, it is necessary to switch to a medium-grit (e.g., 120-320 grit) wheel. For some metal components with extremely high surface quality requirements, such as optical lens molds and high-precision mechanical parts, a high-grit (e.g., 500 grit and above) wheel is finally used for fine polishing. Different grit wheels need to be used during the polishing process of metal components. It is also necessary to change the wheel or change different polishing wheel equipment during the polishing process. It is also necessary to transfer the metal components separately, which is inconvenient and results in low polishing efficiency.

[0005] A grinding wheel assembly for polishing metal surfaces is proposed to address the problems mentioned above. Utility Model Content

In addition, the metal components also need to be transported separately, which is inconvenient to use and results in low polishing efficiency of metal components.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a grinding wheel assembly for polishing metal surfaces, including a base;

[0008] A vertical plate is fixedly installed on one side of the top of the base;

[0009] Also includes:

[0010] A grinding wheel assembly is provided on one side of the vertical plate;

[0011] The grinding wheel assembly includes an electric cylinder fixedly installed on one side of the upper part of the inside of the vertical plate, and a movable plate is fixedly installed on the movable section of the electric cylinder. Guide rods are symmetrically installed on one side of the movable plate, and the guide rods are slidably connected to the vertical plate.

[0012] The movable plate has a fixed ring fixedly installed on the other side, and a rotating column is rotatably connected to the other side of the movable plate inside the fixed ring. Three mounting brackets are equidistantly installed on the outer side of the rotating column. A rotating shaft is rotatably connected to the inner side of the mounting bracket, and a grinding wheel body is fixedly installed at one end of the rotating shaft. A positioning bracket is rotatably connected to the outer side of the rotating shaft, and the positioning bracket is fixedly connected to the mounting bracket.

[0013] Preferably, the top and bottom of the movable plate are fixedly installed with support frames, and the support frames are slidably connected with positioning rods. The rotating column is provided with six positioning holes equidistantly on the inner side of the fixed ring. The positioning rods are slidably connected to the fixed ring and are inserted into the positioning holes.

[0014] Preferably, a telescopic spring is fitted on the outer side of each of the two positioning rods, and one end of the telescopic spring is fixedly connected to the support frame, while the other end of the telescopic spring is fixedly installed with a movable frame, which is fixedly connected to the positioning rod.

[0015] Preferably, movable rods are fixedly installed on the adjacent sides of the two movable frames, and support rods are slidably connected inside the movable frames, with one end of the support rods fixedly connected to a fixed ring.

[0016] Preferably, a limiting frame is slidably connected to the outer side of each of the two movable rods, and one end of the limiting frame is fixedly connected to a fixed ring. A rotating rod is rotatably connected to the outside of the fixed ring between the two movable rods. A rotating component is fixedly installed at one end of the rotating rod, and a connecting rod is symmetrically hinged to one side of the rotating component. The ends of the two connecting rods away from the rotating component are respectively hinged to the two movable rods.

[0017] Preferably, a handle is fixedly installed on the outer side of the rotating rod, and a limit hole is opened on the upper side of one side of the upright plate, and one end of the handle is inserted into the limit hole.

[0018] Preferably, a servo motor is fixedly installed on one side of the upright plate, which is located on the side of the electric cylinder. A connecting shaft is fixedly installed at the output end of the servo motor. A connecting groove is opened inside the rotating shaft, and the connecting shaft is inserted into the connecting groove. Three positioning grooves are equidistantly opened on the inner circumferential side of the connecting groove, and three positioning strips are equidistantly installed on the outer circumferential side of the connecting shaft. The positioning strips are inserted into the positioning grooves.

[0019] Compared with the prior art, the beneficial effects of this utility model are: this grinding wheel assembly for polishing metal surfaces allows for the replacement of grinding wheel bodies with different grit sizes according to different polishing processes, meeting the polishing needs of metal components at different stages and improving the polishing efficiency of metal components. The specific details are as follows:

[0020] 1. When polishing metal components, the electric cylinder can be activated to move the movable plate, causing the handle to disengage from the limiting hole and the rotating shaft to disengage from the connecting shaft. Then, the handle can be rotated to rotate the rotating rod, causing the rotating component on the rotating rod to rotate. After the rotating component rotates, the connecting rod can push the two movable rods away from each other, causing the movable frame to move. The movement of the movable frame can cause the positioning rod to slide on the support frame and stretch the telescopic spring, causing the positioning rod to disengage from the positioning hole. This causes the rotating column to lose its limiting position, allowing it to rotate. The three grinding wheel bodies have different grit numbers, allowing the appropriate grit grinding wheel body to rotate to one side of the connecting shaft. The handle can then be released, and the telescopic spring will reset the positioning rod, allowing it to insert into the corresponding positioning hole. This positions the rotating column. Afterward, the electric cylinder can be used to reset the movable plate, allowing one end of the handle to insert into the limiting hole. This prevents the rotating rod from rotating accidentally during metal component polishing, allows for the selection of a suitable grit grinding wheel body for polishing, and enables the replacement of different grit grinding wheel bodies according to different polishing processes, meeting the polishing needs of metal components at different stages and improving polishing efficiency.

[0021] 2. When switching between different grinding wheel bodies, the rotating shaft moves and the connecting shaft disengages from the connecting groove. When the grinding wheel body is reset and moved, the rotating shaft moves so that the connecting shaft can be inserted into the connecting groove. The inside of the positioning groove is flared on one side, which facilitates the insertion of the positioning strip into the positioning groove. Then, the servo motor can be started to drive the connecting shaft to rotate, which can drive the rotating shaft to rotate, so that the grinding wheel body can rotate, and the metal components can be polished.

Limiting frames 217 are slidably connected to the outer sides of both movable rods 216, and one end of the limiting frame 217 is fixedly connected to the fixed ring 204. The outer side of the fixed ring 204 is... A rotating rod 218 is rotatably connected between two movable rods 216. A rotating component 219 is fixedly mounted on one end of the rotating rod 218, and connecting rods 220 are symmetrically hinged to one side of the rotating component 219. The ends of the two connecting rods 220 away from the rotating component 219 are respectively hinged to the two movable rods 216, so that the rotation of the rotating rod 218 can drive the movable rods 216 to move. A handle 221 is fixedly mounted on the outer side of the rotating rod 218, and a limiting hole 222 is provided on the upper side of one side of the upright plate 101.

A servo motor 224 is fixedly installed on one side of the upright plate 101, which is located on the side of the electric cylinder 201. A connecting shaft 225 is fixedly installed at the output end of the servo motor 224. A connecting groove 223 is opened inside the rotating shaft 207. The connecting shaft 225 is inserted into the connecting groove 223. Three positioning grooves 226 are equidistantly opened on the inner circumference of the connecting groove 223.

[0032] Working principle: Before using this grinding wheel assembly for polishing metal surfaces, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 6As shown, when polishing metal components, the electric cylinder 201 can be activated to move the movable plate 202, causing the handle 221 to disengage from the limiting hole 222, and the rotating shaft 207 to disengage from the connecting shaft 225. Then, the handle 221 can be rotated to rotate the rotating rod 218, causing the rotating component 219 on the rotating rod 218 to rotate. After the rotating component 219 rotates, it can push the two movable rods 216 away from each other via the connecting rod 220, causing the movable frame 214 to move. The movement of the movable frame 214 can cause the positioning rod 211 to slide on the support frame 210 and stretch the telescopic spring 213, causing the positioning rod 211 to disengage from the positioning hole 212. This causes the rotating column 205 to lose its limit, allowing the rotating column 205 to rotate. The three grinding wheel bodies 208... The different grit sizes allow the grinding wheel body 208 of the appropriate grit size to rotate to one side of the connecting shaft 225, releasing the handle 221. Under the action of the telescopic spring 213, the positioning rod 211 is reset, allowing it to insert into the corresponding positioning hole 212, thus positioning the rotating column 205. Afterward, the moving plate 202 can be reset by the electric cylinder 201, allowing one end of the handle 221 to be inserted into the limiting hole 222. This prevents the rotating rod 218 from rotating accidentally when polishing metal components, allowing the appropriate grit size grinding wheel body 208 to be selected for polishing. Different grit sizes of grinding wheel body 208 can be changed according to different polishing processes to meet the polishing needs of metal components at different stages and improve the polishing efficiency of metal components.

[0033] When switching between different grinding wheel bodies 208, the rotating shaft 207 moves, and the connecting shaft 225 disengages from the connecting groove 223. When the grinding wheel body 208 is reset and moved, the rotating shaft 207 moves so that the connecting shaft 225 can be inserted into the connecting groove 223. The inside of the positioning groove 226 is flared on one side, which facilitates the insertion of the positioning strip 227 into the positioning groove 226. Then, the servo motor 224 can be started to drive the connecting shaft 225 to rotate, which can drive the rotating shaft 207 to rotate, so that the grinding wheel body 208 can rotate, and the metal components can be polished.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
