[0003] The working principle of the existing vertical grinder is to drive the motor shaft and the grinding head to rotate through the drive of the motor to achieve the purpose of grinding. As the motor shaft rotates at a high speed, it and the end cover of the machine body will generate more friction. If this continues for a long time, it is easy to cause the motor shaft to wear, resulting in the grinding disc to vibrate during use, thereby affecting the normal grinding of the workpiece. For this reason, we propose a grinder anti-vibration mechanism to solve the above problem. Utility Model Content

DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0022] Reference Figure 1-4 , a grinder anti-vibration mechanism, including a grinder body 1, with a rotating shaft 2 symmetrically connected to both ends of the grinder body 1, and a grinding head 3 is sleeved on the ends of the rotating shaft 2. The installation method of the rotating shaft 2 and the grinding head 3 is the existing technology, which will not be repeated here. A connecting block 4 is sleeved on the outer side of the rotating shaft 2, and an oil storage tank 5 is opened inside the connecting block 4. A sealing plug 6 is clamped inside the connecting block 4 above the oil storage tank 5, and a drainage groove is opened on the inner wall of the connecting block 4 below the oil storage tank 5. The opening of the drainage groove can facilitate the injection of lubricating oil into the outer surface of the rotating shaft 2.
[0023] Further, see Figure 3 It can be seen that the front and back sides of the connecting block 4 are symmetrically connected with the mounting blocks 17, and the interior of the mounting blocks 17 are connected to the grinder body 1 through bolts. By setting two groups of mounting blocks 17, the connecting block 4 can be installed at the side position of the grinder body 1.
[0024] Further, see Figure 2 It can be known that a sealing sleeve 18 is provided at the bottom opening of the connecting block 4, and the inner wall of the sealing sleeve 18 and the outer surface of the rotating shaft 2 are tightly fitted. The setting of the sealing sleeve 18 can effectively prevent the injected lubricating oil from leaking.
[0025] Further, see Figure 2 and Figure 4 It can be known that fixed blocks 9 are symmetrically distributed on the inner wall of the bottom end of the oil storage tank 5, and a movable plate 10 is engaged with the side of the fixed blocks 9 that are close to each other. The top of the movable plate 10 is connected to the support plate 12 through a connecting rod 11, and a pulling rod 13 is vertically connected to the upper side of the support plate 12. A vertical rod 15 is vertically inserted on the left side of the support plate 12, and the upper end of the vertical rod 15 is connected to the inner wall of the oil storage tank 5, and the lower end of the vertical rod 15 is fixedly connected to the fixed block 9. Through the mutual cooperation of the fixed block 9 and the movable plate 10, the top of the drainage groove can be blocked. When lubrication is needed, the staff only needs to pull the pulling rod 13 to drive the movable plate 10 to lift up, so that the lubricating oil flows out from the gap between the fixed block 9 and the movable plate 10, which can facilitate the staff to control the injection amount of the lubricating oil and realize the control of the injection time.
[0026] Further, see Figure 3 and Figure 4It can be seen that an observation port 8 is opened on the side of the connecting block 4, and the inner wall of the observation port 8 is connected to a transparent plate. Through the cooperation between the observation port 8 and the transparent plate, the staff can check the capacity of the lubricating oil inside the grinder body 1 conveniently so that the staff can replenish it in time.
[0027] Further, see Figure 4 It can be known that the longitudinal section of the support plate 12 is set to an arc structure, and a connecting spring 16 is connected to the bottom of the support plate 12, and the other end of the connecting spring 16 is fixedly connected to the fixed block 9. The support plate 12 set by the arc structure can prevent the retention of lubricating oil. Combined with the setting of the vertical rod 15 and the connecting spring 16, the support plate 12 can be guided to ensure the linear sliding of the movable plate 10 and the sealing effect above the drainage groove.
[0028] Further, see Figure 4 It can be known that the top end of the pulling rod 13 extends to the oil storage tank 5, and the upper side of the oil storage tank 5 is connected with a pulling block 14, and the side of the sealing plug 6 is connected to the connecting block 4 through a connecting rope 7. The setting of the pulling block 14 can facilitate the staff to pull the pulling rod 13, and the setting of the connecting rope 7 can prevent the sealing plug 6 from being lost.
[0029] Working principle: When the utility model is used, the staff can first place the device at a suitable position, and then start the grinder body 1 to drive the rotation of the shaft 2, and use the grinding head 3 set at the end of the shaft 2 to grind the workpiece. After grinding for a period of time, the staff can open the sealing plug 6 set above the connecting block 4, so that the lubricating oil can be poured into the oil storage tank 5 for temporary storage, and the observation port 8 set on the side of the connecting block 4 can prevent the lubricating oil from being injected too much. After the injection is completed, the sealing plug 6 can be clamped on the top of the connecting block 4 again to seal the oil storage tank 5;
[0030] Then the staff can pull up the pulling block 14, so that the pulling rod 13 drives the support plate 12 to lift up. At this time, the movable plate 10 arranged under the support plate 12 can move inside the oil storage tank 5, and the oil stored in the oil storage tank 5 can fall through the gap between the fixed block 9 and the movable plate 10, so that the lubricating oil flows into the outer surface of the rotating shaft 2 through the drainage groove, and then with the continuous rotation of the rotating shaft 2, the lubricating oil can penetrate into the gap between the rotating shaft 2 and the end cover to realize the lubrication operation on the outer surface of the rotating shaft 2, thereby effectively preventing the rotating shaft 2 from wearing and shaking during rotation. The above is the entire working principle of the utility model.
[0031] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
