Description

Technical Field

[0001] The utility model relates to the field of concentric adjusting seats, in particular to a concentric adjusting seat. Background Art

[0002] The opening and closing rotating flange in the bell jar liquid injection machine usually needs to be adjusted concentrically with the bottom fixing seat to ensure the stability and normal operation of the opening and closing rotating flange during operation and facilitate the opening of the opening and closing rotating flange.

[0003] Usually, when adjusting the concentricity of the adjusting seat, after locking the fixing seat and the flange, adjusting bolts or nuts are used for fine adjustment. These steps usually require special tools, such as wrenches or adjusting screwdrivers, to ensure that the flange can rotate along the correct axis. During the adjustment process, it is necessary to repeatedly check and adjust to ensure that the required concentricity requirements are met.

[0004] Usually, when adjusting the concentricity of the adjusting seat, the whole adjusting seat is adjusted. However, the overall adjustment may increase the complexity of the adjustment, resulting in the need for multiple adjustments to reach the ideal position, which may consume more time and human resources, especially when the operating environment is limited or the accuracy requirements are high.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Refer to Figure 1 , Figure 8 , Figure 10 , an embodiment provided by the present invention: A concentric adjusting seat, including a base 1, a replacement mechanism is provided at the top end of the inner surface of the base 1. The replacement mechanism includes a fixed block 2. The bottom end of the outer surface of the fixed block 2 is fixedly connected to the top end of the outer surface of the base 1 through bolts. Through the bolts at the top end of the outer surface of the base 1, the fixed block 2 provides a fixed support effect. The left side of the inner surface of the fixed block 2 is elastically connected to a fixed shaft 4 through a volute spring 14, so that the fixed shaft 4 can always maintain an upward-expanded effect without being affected by external forces. A cam follower 5 is rotatably connected to the outer surface of the fixed shaft 4, so that the cam follower 5 can rotate along the outer surface of the fixed shaft 4. The right side of the inner surface of the fixed block 2 is elastically connected to an inclined block 15 through a spring 16, so that the inclined block 15 can always maintain an inward-moving effect without being affected by external forces. A pin 13 is slidably connected to the inner surface of the inclined block 15, so that the pin 13 can move horizontally along the inner surface of the inclined block 15. And because the left side of the pin 13 is a slope, when the pin 13 moves horizontally along the inner wall of the inclined block 15, it can drive the inclined block 15 to move outward. The left side of the outer surface of the fixed shaft 4 is rotatably connected to the left side of the inner surface of the fixed block 2, so that the fixed shaft 4 can expand upward along the left side of the inner surface of the fixed block 2. The outer surface of the inclined block 15 is slidably connected to the right side of the inner surface of the fixed block 2, so that the inclined block 15 can move horizontally along the inner surface of the fixed block 2. The left side of the inclined block 15 is clamped with the right side of the fixed shaft 4, so that the fixed shaft 4 can be fixed at a specified position when it is clamped with the inclined block 15. The outer surface of the pin 13 is slidably connected to the right side of the inner surface of the fixed block 2, so that the pin 13 can move horizontally along the inner surface of the fixed block 2.

[0039] Refer to Figure 4 , Figures 6 - 7, on the right side of the outer surface at the top of the fixed block 2, there is a sliding connection with an adjusting block 6, enabling the adjusting block 6 to move horizontally along the right side of the outer surface at the top of the fixed block 2, and having the effect of fixing the fixed block 2 on the outer surface of the adjusting block 6 by using bolts. At the top of the inner surface of the adjusting block 6, there is a sliding connection with a tightening screw 7, enabling the tightening screw 7 to move horizontally along the top of the inner surface of the adjusting block 6. At the bottom of the inner surface of the adjusting block 6, there is a threaded connection with a loosening screw 8, enabling the loosening screw 8 to move horizontally along the inner surface of the adjusting block 6 by rotation. At the inner surface of the adjusting block 6, there is a threaded connection with a fixing column 17, enabling the fixing column 17 to be fixed on the inner surface of the adjusting block 6 by rotation. At the top of the outer surface of the fixing column 17, there is a rotational connection with a cam follower 5, enabling the cam follower 5 to rotate along the top of the outer surface of the fixing column 17.

[0040] Refer to Figure 5 , Figure 7 , Figure 9 , on the right side of the outer surface of the tightening screw 7, there is a threaded connection with the top of the inner surface on the right side of the fixed block 2. When the tightening screw 7 moves horizontally along the inner surface of the fixed block 2 due to rotation, it can drive the adjusting block 6 to move together. On the right side of the outer surface of the loosening screw 8, there is a contact connection with the right side of the outer surface of the fixed block 2. When the loosening screw 8 is tightened, it can drive the adjusting block 6 to move outward. On the left side of the outer surface of the loosening screw 8, there is a threaded connection with a locking nut 9, enabling the loosening screw 8 to be prevented from rotating due to the locking nut 9. One end of the scroll spring 14 is fixedly connected to the left side of the outer surface of the fixed shaft 4, and the other end of the scroll spring 14 is fixedly connected to the left side of the inner surface of the fixed block 2. When the fixation on the right side of the fixed shaft 4 is released, the fixed shaft 4 can be unfolded upward due to the elastic force of the scroll spring 14.

[0041] Refer to Figures 2 - 3 , Figure 8 One end of the spring 16 is fixedly connected to the right side of the inner surface of the fixed block 2, and the other end of the spring 16 is fixedly connected to the right side of the outer surface of the inclined block 15. When the bolt 13 is pulled out, the inclined block 15 can move inward due to the elastic force of the spring 16. The outer surface of the cam follower 5 is in contact connection with a buckle rotating flange 10, enabling the buckle rotating flange 10 to rotate along the outer surface of the cam follower 5. The inner surface of the buckle rotating flange 10 is fixedly connected to a bell cover base 11, providing a fixing effect for the bell cover base 11 through the inner surface of the buckle rotating flange 10. The bottom of the outer edge of the bell cover base 11 is in contact connection with the top of the outer surface of the bottom support bearing 3, enabling the bottom of the outer surface of the bell cover base 11 to rotate along the bottom support bearing 3. There are multiple groups of adjusting seats, and they are evenly arranged on the outer surface of the bell cover base 11, enabling the multiple groups of adjusting seats to limit the bell cover base 11 in a specified position.

[0042] Working principle: When using the device, first unscrew the screw on the adjusting block 6 to release the fixation of the adjusting block 6. Then loosen the tightening screw 7 and also loosen the locking nut 9. Then tighten the jacking screw 8 to drive the cam follower 5 and the adjusting block 6 to move outwards. When the adjusting block 6 moves outwards to the specified position, place the opening rotating flange 10 on the top of the fixed block 2. Then first loosen the jacking screw 8, and then tighten the tightening screw 7 to drive the cam follower 5 and the adjusting block 6 to move towards the center of the circle, and make the cam follower 5 press against the outer surface of the opening rotating flange 10, so that the opening rotating flange 10 can be fixed at the specified position under the action of multiple groups of adjusting seats. Then tighten the locking nut 9 to prevent the jacking screw 8 from falling off due to vibration. Finally, fix the screw on the adjusting block 6 again.

[0043] When it is necessary to replace the bottom support bearing 3, insert the pin 13 along the right inner surface of the fixed block 2 so that the left shoe surface of the pin 13 contacts the inclined surface of the inner surface of the inclined block 15. Then continue to press the pin 13 to drive the two groups of inclined blocks 15 to move outwards, and at the same time release the fixation on the right side of the fixed shaft 4. Then the fixed shaft 4 will move upwards due to the elastic force of the scroll spring 14 and drive the bottom support bearing 3 to move together. Then remove the elastic retaining ring on the right side of the fixed shaft 4, and then pull out the bottom support bearing 3 obliquely upwards. Then insert the new bottom support bearing 3 obliquely downwards along the outer surface of the fixed shaft 4, and then fix the new bottom support bearing 3 on the fixed shaft 4 through the elastic retaining ring. Then press down the bottom support bearing 3 so that the bottom end of the outer surface on the right side of the fixed shaft 4 presses against the inclined surfaces of the two groups of inclined blocks 15, causing the two groups of inclined blocks 15 to move outwards simultaneously. When the fixed shaft 4 moves to the specified position, the two groups of inclined blocks 15 will move inwards due to the elastic force of the spring 16 and be clamped with the inner surface on the right side of the fixed shaft 4, fixing the fixed shaft 4 and the bottom support bearing 3 at the specified position.
