Description

Technical Field

[0001] The utility model relates to the field of grinding and polishing, in particular to a multifunctional grinding and polishing system. Background Technique

[0002] The two processing methods of grinding and polishing are extremely similar. Both use tools to rub on the surface of the workpiece, making the uneven parts on the surface of the workpiece smoother. The difference is that polishing is more delicate than grinding and requires the surface of the workpiece to have a certain gloss to increase the aesthetics of the workpiece.

[0003] When grinding and polishing the workpiece, a certain order needs to be followed. First, grind and then polish. And during the grinding and polishing process, rougher tools need to be used first, and then finer tools, operating in the order from rough to fine.

[0004] However, in the prior art, replacing grinding tools with different thicknesses can only be done manually, and the grinding and polishing device cannot automatically replace the grinding tools during the operation process, reducing the efficiency of grinding and polishing. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a multifunctional grinding and polishing system. By magnetically driving the central shaft, the grinding wheels move, while the position of the workpiece remains unchanged. Thus, according to the normal order of grinding and polishing, different fineness grinding wheels can be automatically switched during the grinding and polishing process, which is more convenient and also improves the efficiency of grinding and polishing, and can effectively solve the problems in the background technique.

[0006] To achieve the above object, the technical solution adopted by the utility model is: a multifunctional grinding and polishing system, including a base.

[0008] One end of the central shaft facing the first sleeve extends into the first sleeve and is fixedly provided with an iron block. A fixed rod is provided inside the first sleeve. An electromagnet is fixedly provided on one side of the fixed rod facing the iron block. The magnetic force of the electromagnet can adsorb the fixed rod and control the movement of the grinding wheels and the central shaft.

[0009] Further, one end of the first sleeve away from the central shaft is provided with a second vertical plate through a bearing. The second vertical plate is provided at the top end of the base through bolts.

[0010] One end of the fixed rod away from the iron block is fixedly connected to the second vertical plate.

[0023] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the following will further elaborate on the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0024] As Figures 1-5 shown, the present utility model provides a multifunctional grinding and polishing system, including a base 1. A central shaft 9 is provided at the top of the base 1. A plurality of grinding wheels 8 are sleeved on the outer end of the central shaft 9. A first sleeve 10 and a second sleeve 11 are respectively provided at both ends of the central shaft 9. The grinding wheels 8 closer to the second sleeve 11 are finer.

[0025] One end of the central shaft 9 facing the second sleeve 11 extends into the second sleeve 11 and is fixedly provided with a spring 1101. One end of the spring 1101 is fixedly connected to the inner wall of the second sleeve 11. The position of the central shaft 9 and the grinding wheels 8 can be controlled by the elastic force of the spring 1101.

[0026] One end of the central shaft 9 facing the first sleeve 10 extends into the first sleeve 10 and is fixedly provided with an iron block 1001. A fixed rod 1002 is provided inside the first sleeve 10. An electromagnet 1003 is fixedly provided on the side of the fixed rod 1002 facing the iron block 1001. The magnetic force of the electromagnet 1003 can adsorb the fixed rod 1002 and control the movement of the grinding wheels 8 and the central shaft 9.

[0027] During the grinding process, the rotation of the central shaft 9 drives the grinding wheel 8 to rotate. During the rotation of the grinding wheel 8, it contacts the stationary workpiece, thus generating friction with the workpiece and achieving the purpose of grinding and polishing. During this process, the electromagnet 1003 is energized to generate magnetic force, and the magnetic force is continuously increased. Under the adsorption of the magnetic force, the iron block 1001 drives the central shaft 9 and the grinding wheel 8 to move towards the direction close to the electromagnet 1003. As a result, the spring 1101 is gradually stretched. During this process, the position of the workpiece is kept stationary, and the grinding wheel 8 will move relative to the workpiece. The contact position between the grinding wheel 8 and the workpiece will change, thereby achieving the purpose of automatically switching different grinding wheels 8. Moreover, the closer the central shaft 9 is to the electromagnet 1003, the finer the grinding wheel 8 in contact with the workpiece will be. Thus, according to the normal sequence of grinding and polishing, different fine-grind grinding wheels 8 can be automatically switched during the grinding and polishing process, which is more convenient and also improves the efficiency of grinding and polishing.

[0028] It is possible to adjust the change of the magnetic force according to the actual situation of processing, such as Figure 1 、 2 As shown in FIG. 5, one end of the first sleeve 10 away from the central shaft 9 is provided with a second vertical plate 4 through a bearing, and the second vertical plate 4 is provided on the top end of the base 1 through bolts;

[0029] One end of the fixing rod 1002 away from the iron block 1001 is fixedly connected to the second vertical plate 4.

[0030] A controller 5 is fixedly provided on the second vertical plate 4. An adjustment switch 2 is fixedly provided on the top end of the base 1. The adjustment switch 2 can control the change speed of the magnetic force of the electromagnet 1003. The adjustment switch 2 is provided at the input end of the controller 5, and the electromagnet 1003 is provided at the output end of the controller 5.

[0031] One end of the second sleeve 11 away from the central shaft 9 is provided with a first vertical plate 3 through a bearing. The first vertical plate 3 is provided on the top end of the base 1 through bolts. A motor 6 for driving the second sleeve 11 is fixedly provided on the first vertical plate 3. The motor 6 is provided at the output end of the controller 5.

[0032] By driving the second sleeve 11 to rotate by the motor 6, the central shaft 9 inserted inside the second sleeve 11 is thus driven. The other end of the central shaft 9 is inserted into the first sleeve 10, and the first sleeve 10 also rotates accordingly. And by the adjustment switch 2, the increasing speed of the magnetic force of the electromagnet 1003 during the working process can be set, and then the moving speed of the grinding wheel 8 and the central shaft 9 during the grinding and polishing process can be set and adjusted.

[0033] In order to fix the grinding wheel 8 at the outer end of the central shaft 9, such as Figure 2 、 3As shown, a limit plate 12 is fixedly provided at the outer end of the central shaft 9. A moving seat 13 is sleeved on the outer end of the central shaft 9. A fastening bolt is provided at the outer end of the moving seat 13 by means of a thread. A clamping plate 14 is fixedly provided at the outer end of the moving seat 13. The grinding wheel 8 is clamped between the clamping plate 14 and the limit plate 12.

[0034] Since the cross-section of the central shaft 9 is rectangular, the grinding wheel 8 sleeved on the outer end of the central shaft 9 can rotate synchronously with the central shaft 9. After the grinding wheels 8 are sleeved on the outer end of the central shaft 9 in sequence, the moving seat 13 is slid so that the clamping plate 14 on the moving seat 13 is in close contact with one of the grinding wheels 8. After the fastening bolt on the moving seat 13 is tightened, the positions of the moving seat 13 and the clamping plate 14 can be fixed, so that the grinding wheel 8 is clamped and fixed between the limit plate 12 and the clamping plate 14.

[0035] For dust prevention, as Figure 1 shown, a protective cover 7 is fixedly provided at the top of the base 1. The grinding wheel 8 and the second sleeve 11 are both arranged inside the protective cover 7, and the protective cover 7 can play a protective role for the grinding wheel 8.

[0036] By arranging the protective cover 7 on the outer side of the grinding wheel 8, during the grinding process, the workpiece is always located at one end of the protective cover 7 facing the first sleeve 10. Therefore, the protective cover 7 can help the workpiece maintain its position during the grinding process, and at the same time play a certain role in shielding the grinding wheel 8 and the central shaft 9, reducing the dispersion of dust.

[0037] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
