However, during the manual grinding process, the sample is subjected to the lateral force of the rotation of the grinding disc and is very likely to fly out. Once the sample flies out, it is easy to injure nearby personnel and equipment, and the splashing of grinding paste will pollute the surrounding environment, reducing the use effect of the metallographic grinder. Therefore, a protective device for the metallographic grinder is needed. Utility Model Content

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0027] Embodiment 1, as Figure 1-Figure 5 As shown, the utility model provides a metallographic grinder protection device, including a grinder body 1, a protective cover 2 is placed on the top of the grinder body 1, two vertical grooves 3 are opened on one side of the outer wall of the protective cover 2, the inner surface walls of the two vertical grooves 3 are movably embedded with L-shaped support blocks 4, a baffle 5 is fixedly installed between the tops of the two L-shaped support blocks 4, a visual window 6 is fixedly installed on one side of the outer wall of the baffle 5, two connecting blocks 7 are fixedly installed on the outer wall of the baffle 5, two horizontal plates 8 are fixedly installed on the outer wall of the protective cover 2, forward and reverse motors 9 are fixedly installed on the tops of the two horizontal plates 8, and driving rods 10 are fixedly installed on one side of the outer walls of the two forward and reverse motors 9.

[0028] The effect achieved by the entire embodiment 1 is that when in use, the staff puts the sample on the grinder body 1 and performs manual grinding. At this time, the two forward and reverse motors 9 are started, and the two driving rods 10 and the two gears 11 are driven to rotate by the two forward and reverse motors 9. Since the two gears 11 are meshed and connected with the two tooth rows 12, the tops of the two tooth rows 12 are fixedly connected with the bottoms of the two connecting blocks 7, thereby driving the two tooth rows 12 and the two connecting blocks 7 to move up and down. Under the action of the two limit blocks 13, the two tooth rows 12 will not be separated from the two gears 11. Because the two sides of the baffle 5 are fixedly connected with the two connecting blocks 7, and the two L-shaped brackets 4 installed at the bottom of the baffle 5 are movably embedded in the two vertical grooves 3, the baffle 5 is driven to move up and down until it is moved to a suitable height. Under the action of the visual window 6, it not only does not affect the staff's observation of the sample grinding effect, but also prevents the sample from splashing out and injuring themselves during the grinding process. Under the action of the protective cover 2, it can also prevent the sample from flying out and injuring nearby personnel and equipment, thereby improving the use effect of the metallographic grinder protective device.

[0029] Embodiment 2, as Figure 2-Figure 5 As shown, the outer walls of the two driving rods 10 are fixedly sleeved with gears 11, the outer walls of the two gears 11 are meshed with tooth rows 12, and the tops of the two tooth rows 12 are fixedly connected to the bottoms of the two connecting blocks 7, and the bottoms of the two tooth rows 12 are fixedly installed with limit blocks 13, the outer wall of the protective cover 2 is fixedly installed with two support rods 14, and the tops of the two support rods 14 are fixedly connected to the bottoms of the two cross plates 8, and the outer wall of the protective cover 2 is fixedly installed with two mounting blocks 15, and the tops of the two mounting blocks 15 are opened with strip holes 16. Two fixed blocks 17 are fixedly installed on the top of the grinder body 1, and the outer walls of the two fixed blocks 17 are movably inserted into the two strip holes 16, the inner walls of the two fixed blocks 17 are threadedly connected with bolts 18, the outer walls of the two bolts 18 are movably sleeved with limit strips 19, and the bottoms of the two limit strips 19 are in contact with the tops of the two mounting blocks 15, a strip column 20 is fixedly installed on the top of the grinder body 1, a strip sleeve 21 is fixedly installed on the back of the protective cover 2, and the outer wall of the strip column 20 is movably inserted into the inside of the strip sleeve 21.

[0030] The effect achieved by the entire embodiment 2 is that when installing the protective cover 2, the protective cover 2 is first directly sleeved on the strip column 20 through the strip sleeve 21 installed on the back. At this time, the mounting blocks 15 installed on both sides of the protective cover 2 are sleeved on the two fixing blocks 17 through the two strip holes 16, and the two fixing blocks 17 are completely inside the two strip holes 16, and then the two limiting strips 19 are sleeved on the two bolts 18, and the two bolts 18 are threadedly connected inside the two fixing blocks 17 until the two limiting strips 19 are between the two bolts 18 and the two fixing blocks 17, and the two limiting strips 19 are perpendicular to the two fixing blocks 17 and the two mounting blocks 15, and then through the action of the two limiting strips 19, the protective cover 2 can be limited on the grinder body 1, maintaining the stability of the installation. After the grinder is used for a long time, it is convenient for the staff to remove the protective cover 2 and clean or repair the interior, thereby ensuring the effect of the metallographic grinder on the sample grinding, and further improving the use effect of the metallographic grinder protective device.

[0031] Working principle: First, when the staff is grinding the sample on the metallographic grinder, they start the two forward and reverse motors 9 to drive the two driving rods 10 and the two gears 11 to rotate. Since the connecting blocks 7 installed on both sides of the baffle 5 are connected to the tops of the two tooth rows 12, and the two L-shaped brackets 4 installed at the bottom of the baffle 5 move inside the two vertical slots 3, the two gears 11 drive the two tooth rows 12 to move up and down, and the baffle 5 can be driven to move up and down until it is moved to a suitable height. Under the action of the visual window 6 and the protective cover 2, the sample can be prevented from splashing out and injuring oneself and the surrounding during grinding. The surrounding staff and equipment can also be prevented from splashing and polluting the surrounding environment with grinding paste. Secondly, the protective cover 2 is put on the two fixed blocks 17 through the two bar holes 16, and then the bolts 18 with two limit strips 19 are threadedly connected to the inside of the two fixed blocks 17, so that the two limit strips 19 and the two fixed blocks 17 are perpendicular to each other, and then the two mounting blocks 15 are limited on the two fixed blocks 17, thereby ensuring the stability of the protective cover 2 on the grinder body 1. When the interior needs to be repaired or cleaned, it is convenient for the staff to disassemble and assemble the protective cover 2. Generally speaking, the use effect of the protective device of the metallographic grinder is improved.

[0032] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
