Description

Technical Field

[0001] This utility model relates to the field of polishing technology, specifically to a grinding head structure for a polishing machine. Background Technology

[0002] As an indispensable piece of equipment in modern industry, the design and optimization of the polishing head structure of a polishing machine directly affects polishing efficiency, processing quality, and the overall performance of the equipment. The design of the polishing machine's grinding head structure needs to consider a variety of factors, including processing materials, processing precision, production efficiency, and equipment costs, to meet different processing needs.

[0003] For example, an existing patent (publication number: CN202640129U) discloses an external polishing head structure for a polishing machine, including a base, a lifting system, a rotating system, a polishing head system, and a deceleration system. This utility model, through the combined action of the lifting system, rotating system, polishing head system, and deceleration system, enables the polishing head to move up and down, left and right, and rotate.

[0004] However, the external polishing head structure of the polishing machine designed above still has some drawbacks in actual use: Although the external polishing head structure of the polishing machine can realize the up-down movement, left-right movement, and rotation of the polishing head through the combined action of the lifting system, rotation system, grinding head system and deceleration system, the grinding head system cannot be replaced with different types of grinding heads at any time, and the polishing machine cannot adapt to the polishing needs of different materials and surfaces at any time, which makes the range of applicable workpieces smaller.

[0005] To address these issues, we designed a grinding head structure for a polishing machine. Utility Model Content

[0006] The purpose of this invention is to provide a grinding head structure for a polishing machine to solve the problems mentioned in the background art.

[0008] Furthermore, the first connecting member includes a telescopic rod fixedly connected to the top of the second grinding head, and a first grinding head is provided on one side near the telescopic end of the telescopic rod. The first grinding head is provided with a groove adapted to the telescopic rod. The first grinding head is "umbrella" shaped, and the telescopic rod is fixedly connected in the groove. The surfaces of the first grinding head and the second grinding head are integrally formed with different polishing textures.

[0009] Furthermore, the polishing assembly also includes a sealing gasket fixedly connected to the bottom surface of the polishing box, the inner wall of the sealing gasket abutting against the connecting rod, and the polishing box containing polishing sand.

[0010] Furthermore, the polishing assembly also includes two polishing rings fixedly connected inside the polishing box, each polishing ring having multiple polishing balls rolled on it, the polishing balls being distributed in a ring array on each polishing ring.

[0011] Furthermore, a polishing ring is provided between the two polishing rings. One side of the polishing ring is fixedly connected to the inner wall of the polishing box, and a polishing roller is rotatably provided on the other side of the polishing ring. The polishing roller has polishing patterns integrally formed on it.

[0012] Furthermore, the polishing assembly also includes a mounting box fixedly connected to the polishing box.

[0018] 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.

[0019] Please see Figure 1-5This utility model provides a technical solution: a grinding head structure for a polishing machine, including a servo motor 3, a polishing assembly 2 on the top of the servo motor 3, a polishing box 203 rotatably connected to the drive end of the servo motor 3, the drive end of the servo motor 3 extending into the polishing box 203, a second grinding head 209 disposed inside the polishing box 203, a connecting rod 205 fixedly sleeved on the second grinding head 209, the connecting rod 205 fixedly sleeved on the drive end of the servo motor 3, and a first connecting member disposed on the top of the second grinding head 209.

[0020] The first connecting member includes a telescopic rod 208 fixedly connected to the top of the second grinding head 209. A first grinding head 204 is provided on one side near the telescopic end of the telescopic rod 208. The first grinding head 204 is provided with a groove that matches the telescopic rod 208. The first grinding head 204 is "umbrella" shaped. The telescopic rod 208 is fixedly connected in the groove. The surfaces of the first grinding head 204 and the second grinding head 209 are integrally formed and have different polishing textures.

[0021] In practice, the staff will put the polishing sand 207 into the polishing box 203. Depending on the desired polishing effect, the staff will adjust the extension distance of the telescopic rod 208, and then adjust the distance between the first grinding head 204 and the second grinding head 209 to achieve the desired polishing effect. When the polishing has progressed to a certain extent, the top cover 201 can be opened, the servo motor 3 can be stopped, the length of the telescopic rod 208 can be adjusted, and different degrees of polishing can be carried out. The top cover 201 and the mounting box 202 can be fixed again. Only after the entire process is completed can the top cover 201 be opened and the inserted object be taken out.

[0022] See Figure 3 The polishing assembly 2 also includes a sealing gasket 206 fixedly connected to the bottom surface of the polishing box 203. The inner wall of the sealing gasket 206 abuts against the connecting rod 205. The polishing box 203 contains polishing sand 207.

[0023] In practice, the sealing gasket 206 can prevent the polishing sand 207 from leaking from the gaps in the polishing box 203 during the polishing process, thus affecting the use of the servo motor 3.

[0024] See Figure 1-5 As shown, the polishing assembly 2 also includes two polishing rings 211 fixedly connected inside the polishing box 203. Each polishing ring 211 is rolled with multiple polishing balls, which are distributed in a ring array on each polishing ring 211.

[0025] A polishing ring 210 is also provided between the two polishing rings 211. One side of the polishing ring 210 is fixedly connected to the inner wall of the polishing box 203, and a polishing roller is rotatably provided on the other side of the polishing ring 210. The polishing roller has polishing patterns integrally formed on it.

[0026] In practice, when polishing is performed, the polishing ring 211 and polishing pad 210 promote the polishing sand 207 in the polishing box 203, making the polishing of the object more uniform.

[0027] See Figure 5 The polishing assembly 2 also includes a mounting box 202 fixedly connected to the polishing box 203. The mounting box 202 is frustum-shaped, and a top cover 201 is movably provided on the top of the mounting box 202. A second connector is provided at the connection between the top cover 201 and the mounting box 202.

[0028] The second connector includes a connecting shaft 212 fixedly connected to the mounting box 202, and a top cover 201 rotatably connected to the other side of the connecting shaft 212. A locking post is provided on the side of the top cover 201 away from the connecting shaft 212, and a slot for matching the locking post is also provided on the side of the mounting box 202 near the top cover 201.

[0029] In practice, by opening the top cover 201, since there is a connecting shaft 212 between the top cover 201 and the mounting box 202, the top cover 201 will be pressed against the inner wall of the mounting box 202, so that the polishing component 2 is kept open. During polishing, the top cover 201 is fixed by the locking post and the mounting box 202.

[0030] See Figure 1 A drive assembly 1 is provided on the outside of the servo motor 3. The drive assembly 1 includes a shock-absorbing frame 101 provided at both ends of the servo motor 3. The servo motor 3 is fixedly installed on one of the shock-absorbing frames 101, and the polishing assembly 2 is fixedly installed on the other shock-absorbing frame 101. Four shock-absorbing springs 103 are also provided between the two shock-absorbing frames 101. Each shock-absorbing spring 103 has a shock-absorbing sleeve 102 fixedly connected to both ends, and each shock-absorbing sleeve 102 is fixedly connected to the shock-absorbing frame 101.

[0031] In practice, when polishing with the servo motor 3, a lot of vibration will be generated. At this time, the vibration can be reduced by the damping spring 103 between the damping frame 101 and the damping sleeve 102, so that the polishing assembly 2 will not tip over.

[0032] Working principle: When the user needs to polish the item, first place the drive component 1 on a stable table. Then open the top cover 201. Since there is a connecting shaft 212 between the top cover 201 and the mounting box 202, the top cover 201 will be pressed against the inner wall of the mounting box 202, so that the polishing component 2 is kept open. Then the operator puts the polishing sand 207 into the polishing box 203. Adjust the extension distance of the telescopic rod 208 according to the polishing effect, and then adjust the distance between the first grinding head 204 and the second grinding head 209 to initially achieve the polishing effect desired by the operator. Next, place the object to be polished into the polishing box 203. After adjustment, fix the top cover 201 to the mounting box 202 by means of the locking post. At this time, start the servo motor 3. The servo motor 3 drives the connecting rod 205 to rotate and simultaneously drives the second grinding head 209 to rotate, stirring the polishing sand 207 inside the polishing box 203. At this time, the polishing ring 211 and polishing ring 210 promote the polishing sand 207 in the polishing box 203, making the object polished more evenly. When the polishing has been carried out to a certain extent, the top cover 201 can be opened, the servo motor 3 can be stopped, and the length of the telescopic rod 208 can be adjusted to carry out different degrees of polishing. Fix the top cover 201 to the mounting box 202 again. Only after the whole process is completed can the top cover 201 be opened and the object put in be taken out. When in use, the sealing gasket 206 can prevent the polishing sand 207 from leaking from the gaps in the polishing box 203 during the polishing process, thus affecting the use of the servo motor 3; When polishing using the servo motor 3, a lot of vibration will be generated. At this time, the vibration can be reduced by the damping spring 103 between the damping frame 101 and the damping sleeve 102, so that the polishing assembly 2 will not tip over.
