Description

Technical Field

[0001] The present invention relates to the technical field of grinding devices, and specifically to a grinding device for preparing high-precision modular components of a vacuum chamber. Background Art

[0002] High-precision modular components of a vacuum chamber refer to some high-precision component workpieces applied to the vacuum chamber. Since these workpieces need to be applied in a vacuum environment, certain requirements are imposed on the surface of the workpieces, such as some highly demanding smooth surfaces, to ensure the long-term stable use of the vacuum chamber.

[0003] Currently, when preparing existing high-precision modular components of a vacuum chamber, it is generally necessary to first cut the surface of the workpiece to remove the excess part on the surface of the workpiece, and then perform grinding. However, due to the large number of such high-precision modular components of the vacuum chamber and the relatively large size of some workpieces, a considerable amount of time is consumed in the intermediate conveying process. At the same time, for some workpieces that encounter accidents or are difficult to process during cutting, special attention needs to be paid to such workpieces. However, using the method of separating cutting and grinding makes it easy to cause workpiece damage or excessive grinding in the case of inattentive later grinding, affecting the accuracy of the workpiece.

[0031] Refer to Figure 1-7, a grinding device for preparing a modular component of a high-precision vacuum chamber, including a connecting arm 1. At a position near the right end of the top of the connecting arm 1, a driving motor 2 is fixedly connected.

At a position near the outside of the grinding disc 5 at the bottom of the connecting arm 1, an outer protective shell 6 is fixedly connected. At the bottom of the driving motor 2, a first pulley 10 is drivingly connected. An outer side of the first pulley 10 is movably sleeved with a transmission belt 11.

On the side of the cutting tool 15 close to the hinge shaft 34, two connecting members 32 are fixedly connected. The two connecting members 32 are respectively located at the position where the cutting tool 15 is close to the center of the grinding disc 5 and the position where the cutting tool 15 is close to the edge of the grinding disc 5. A push head 29 is movably sleeved on the side of the connecting member 32 away from the cutting tool 15. A pressing head 28 is attached to the side of the push head 29 away from the connecting member 32. A push control rod 20 is fixedly connected to the top of the pressing head 28. A first control ring 7 is fixedly connected to the top of the push control rod 20 close to the inner side of the grinding disc 5. A third control ring 9 is fixedly connected to the top of the push control rod 20 close to the outer side of the grinding disc 5. The provision of the first control ring 7, the second control ring 8 and the third control ring 9 can stably control the cutting tool 15 and ensure the stability of the equipment during use. First pressing rods 17 are fixedly connected to the bottoms of the first control ring 7 and the third control ring 9. A second limiting plate 25 is fixedly connected to the outer surface of the push control rod 20 close to the top. A second spring 26 is provided at the bottom of the second limiting plate 25. A third spring 30 is provided at the bottom of the second spring 26. The third limiting plate 27 is fixedly connected to the grinding disc 5. A fourth limiting plate 31 is provided in the middle of the push head 29. The fourth limiting plate 31 is fixedly connected to the grinding disc 5. A third spring 30 is provided on the side of the fourth limiting plate 31 away from the connecting member 32. The second spring 26 and the third spring 30 can assist the cutting tool 15 to quickly return to its position, facilitating the switching between grinding and cutting of the equipment. The side of the third spring 30 away from the fourth limiting plate 31 is in contact with one end of the push head 29 away from the connecting member 32. A fixing rod 19 is sleeved on the top of the cutting tool 15. A first limiting plate 24 is fixedly sleeved in the middle of the fixing rod 19. A first spring 23 is fixedly connected to the top of the first limiting plate 24. The first limiting plate 24 and the first spring 23 are both located in the inner cavity of the grinding disc 5. The top of the first spring 23 is fixedly connected to the top of the inner cavity of the grinding disc 5. A second control ring 8 is fixedly connected to the top of the fixing rod 19. An electric control telescopic cylinder 16 is fixedly connected to the bottom of the second control ring 8. The bottom of the electric control telescopic cylinder 16 is fixedly connected to the top of the grinding disc 5. Second pressing rods 22 are fixedly connected to the positions of the bottom of the second control ring 8 close to the inner edge and the outer edge. The first control ring 7 is provided inside the second control ring 8, and the third control ring 9 is provided outside the second control ring 8.

[0033] In the present invention, during use, the water delivery pipe can be fixed first through the fixing strap 3. The water delivery pipe is fixedly connected and communicated with the inner side of the bearing ring 4. Then, the electric control telescopic cylinder 16 is started, so that the electric control telescopic cylinder 16 jacks up the second control ring 8, causing the fixing rod 19 and the second extrusion rod 22 to rise. Further, due to the rise of the fixing rod 19, the bottom of the fixing rod 19 is no longer stuck in the cutting tool 15. At the same time, the rise of the second extrusion rod 22 will cause the hydraulic oil in the hydraulic pipe 18 to control the first extrusion rod 17 to descend, driving the first control ring 7 and the third control ring 9 to descend. The descent of the first control ring 7 and the third control ring 9 will drive the push control rod 20 to descend, causing the extrusion head 28 at the bottom of the push control rod 20 to squeeze the propulsion head 29. The propulsion head 29 pushes the connecting piece 32 to move. Then, due to the restriction of the hinge shaft 34 on the cutting tool 15, the cutting tool 15 tilts outward towards the conveying groove 14, causing the cutting head 21 to extend out of the conveying groove 14. Then, the driving motor 2 drives the first belt pulley 10, the first belt pulley 10 drives the transmission belt 11, the transmission belt 11 drives the second belt pulley 12, and the second belt pulley 12 drives the grinding disc 5 to rotate at a low speed, so as to cut the surface of the workpiece through the cutting head 21. After the cutting is completed, the electric control telescopic cylinder 16 can drive the second control ring 8 to return to its original position, and in cooperation with the first spring 23, the second spring 26 and the third spring 30, control the cutting tool 15 and the cutting head 21 to return to their original positions, and limit the position of the cutting tool 15 through the fixing rod 19. Then, by starting the driving motor 2, the driving motor 2 drives the first belt pulley 10, the first belt pulley 10 drives the transmission belt 11, the transmission belt 11 drives the second belt pulley 12, and the second belt pulley 12 drives the grinding disc 5 to rotate at a high speed to polish the surface of the workpiece. At the same time, the water delivery pipe in the bearing ring 4 is used for beam flow transportation, and the water is transported through the conveying groove 14 to clean the debris on the surface of the workpiece.
