Detailed implementation manner

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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.

[0024] Embodiment 1: This embodiment provides a buffer mechanism for the blanking suction cup of a sintering furnace. Refer to Figures 1-4 , specifically, it includes a suction cup 1, a connecting pipe 12, a connecting plate 14, and a mounting plate 114. A flexible sealing ring 11 is fixedly arranged at the bottom of the suction cup 1, and an airtight ring 111 is fixedly arranged at the top of the suction cup 1. The suction cup 1 is slidably connected to the connecting pipe 12. A threaded fixing pipe 13 is fixedly arranged on the connecting pipe 12. The threaded fixing pipe 13 is slidably connected to the connecting plate 14. A fixing nut 15 is threaded on the threaded fixing pipe 13. A mounting nut 16 is threaded on the threaded fixing pipe 13. A connecting nozzle 17 is rotatably arranged on the mounting nut 16. A pair of vertical rods 18 are fixedly arranged on the connecting plate 14. Sealing rings 19 are fixedly arranged on the vertical rods 18. A pair of support columns 112 are fixedly arranged on the connecting plate 14. A first spring 113 is fixedly arranged on the connecting plate 14. The mounting plate 114 is slidably connected to the vertical rods 18. The other ends of the first springs 113 are fixedly connected to the mounting plate 114. A pair of air tanks 115 are fixedly arranged on the mounting plate 114. The sealing rings 19 are slidably connected to the air tanks 115.

[0025] The vertical rods 18 all penetrate through the mounting plate 114. A pair of mounting holes are opened on the mounting plate 114. The connecting nozzle 17 penetrates through the mounting nut 16. The flexible sealing ring 11 is located at the outer extension port of the bottom of the suction cup 1. The sealing rings 19 are all in contact with the inner walls of the air tanks 115. The threaded fixing pipe 13 penetrates through the connecting plate 14. A flexible cushion layer is provided on the support column 112. The vertical rods 18 are respectively located at the centers of the first springs 113.

[0026] In the specific implementation process, as Figure 1 and Figure 2As shown, when the suction cup 1 rapidly descends to suck the sucked object, the flexible sealing ring 11 at the bottom of the suction cup 1 contacts the sucked object first, which can play a certain buffering role. When the flexible sealing ring 11 is squeezed, the suction cup 1 drives the connecting plate 14 to move upward through the connecting pipe 12 and the threaded fixing pipe 13. The connecting plate 14 squeezes the first spring 113 upward and drives the vertical rod 18 to move upward. The vertical rod 18 drives the sealing ring 19 to move upward. The sealing ring 19 squeezes the air in the air tank 115. The air in the air tank 115 will gradually reach saturation when being squeezed, making it impossible to squeeze inward any further. The reaction force increases slowly during squeezing. The first spring 113 absorbs part of the pressure through squeezing. With the combined action of the squeezed air and the first spring 113, the suction cup 1 can be well buffered. Through the coordinated use of the flexible sealing ring 11, the vertical rod 18, the first spring 113, the connecting plate 14, the mounting plate 114, the sealing ring 19 and the air tank 115, when the suction cup 1 rapidly descends and contacts the sucked object, it can play a buffering role for movement and prevent rigid collision between the suction cup and the sucked object.

[0027] Embodiment 2: In Embodiment 1, there is still a problem that different-sized suction cups cannot be replaced flexibly. Therefore, on the basis of Embodiment 1, this embodiment further includes:

[0028] A plurality of fixing holes 2 are formed in the connecting pipe 12. Fixing balls 21 are rotatably arranged in the fixing holes 2. A trapezoidal ring groove 22 is formed in the suction cup 1. A second spring 23 is fixedly arranged on the connecting pipe 12. A mounting cylinder 24 is slidably arranged on the connecting pipe 12. The other end of the second spring 23 is fixedly connected to the mounting cylinder 24. An annular right-angled trapezoidal groove 25 is formed in the inner bottom of the mounting cylinder 24. The fixing holes 2 penetrate through the connecting pipe 12. The inside of the mounting cylinder 24 is in fit with the outer wall of the connecting pipe 12. The fixing holes 2 are distributed in an annular array. The connecting pipe 12 is located at the center of the second spring 23.

[0029] In the specific implementation process, such as Figure 3 and Figure 4When it is necessary to replace the suction cup 1 of different sizes, push the mounting cylinder 24 up and down and squeeze the second spring 23 to make the annular right-angle trapezoidal groove 25 in the mounting cylinder 24 parallel to the fixing hole 2. Pull out the suction cup 1 downward, insert the replaced suction cup 1 into the connecting pipe 12. The suction cup 1 squeezes the fixing ball 21, causing the fixing ball 21 to be squeezed to one side of the annular right-angle trapezoidal groove 25. Insert the suction cup 1 completely into the mounting cylinder 24, making the trapezoidal ring groove 22 on the suction cup 1 horizontal with the fixing hole 2. Release the mounting cylinder 24, and the second spring 23 pushes the mounting cylinder 24 downward. The inclined surface of the annular right-angle trapezoidal groove 25 in the mounting cylinder 24 squeezes the fixing ball 21, causing the fixing ball 21 to slide into the trapezoidal ring groove 22. The inner surface of the annular right-angle trapezoidal groove 25 blocks the fixing hole 2, making the fixing ball 21 unable to move. The fixing ball 21 limits the trapezoidal ring groove 22, limiting the suction cup 1 in the connecting pipe 12. Through the combined use of the fixing hole 2, the fixing ball 21, the trapezoidal ring groove 22, the second spring 23, the mounting cylinder 24 and the annular right-angle trapezoidal groove 25, when it is necessary to replace the suction cup 1, only need to push the mounting cylinder 24 upward to remove the suction cup 1 for replacement, which is very convenient and fast.

[0030] Specifically, the working principle and operation method of the present utility model are as follows:

[0031] Step 1, when the suction cup 1 quickly descends to suck the sucked object, the flexible sealing ring 11 at the bottom of the suction cup 1 first contacts the sucked object, which can play a certain buffering role. When the flexible sealing ring 11 is squeezed, the suction cup 1 drives the connecting plate 14 to move upward through the connecting pipe 12 and the threaded fixing pipe 13. The connecting plate 14 squeezes the first spring 113 upward and drives the vertical rod 18 to move upward. The vertical rod 18 drives the sealing ring 19 to move upward. The sealing ring 19 squeezes the air in the air tank 115. The air in the air tank 115 will gradually reach saturation when being squeezed, making it impossible to squeeze inward anymore. The reaction force also increases slowly during squeezing. The first spring 113 absorbs part of the pressure through squeezing. Through the combined action of the squeezed air and the first spring 113, the suction cup 1 can be well buffered. The flexible sealing ring 11 fits with the sucked object to prevent the sucked object from falling due to air leakage, and the airtight ring 111 prevents air leakage at the connection.

[0032] Step 2, when it is necessary to replace the suction cups 1 of different sizes, push the mounting cylinder 24 up and down to squeeze the second spring 23, so that the annular right-angle trapezoidal groove 25 in the mounting cylinder 24 is parallel to the fixing hole 2. Pull out the suction cup 1 downward, insert the replaced suction cup 1 into the connecting pipe 12. The suction cup 1 squeezes the fixing ball 21, so that the fixing ball 21 is squeezed to one side of the annular right-angle trapezoidal groove 25. Insert the suction cup 1 completely into the mounting cylinder 24, so that the trapezoidal ring groove 22 on the suction cup 1 is horizontal with the fixing hole 2. Release the mounting cylinder 24, and the second spring 23 pushes the mounting cylinder 24 downward. The inclined surface of the annular right-angle trapezoidal groove 25 in the mounting cylinder 24 squeezes the fixing ball 21, so that the fixing ball 21 slides into the trapezoidal ring groove 22. The inner surface of the annular right-angle trapezoidal groove 25 blocks the fixing hole 2, so that the fixing ball 21 cannot move. The fixing ball 21 limits the trapezoidal ring groove 22, so that the suction cup 1 is limited in the connecting pipe 12;

[0033] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
