Description

Technical Field

[0001] The invention relates to the technical field of mechanical seal processing, in particular to a mechanical seal processing fixture with a flipping function. Background Art

[0002] Mechanical seals are one of the most precise and complex basic mechanical components. They are key components of various pumps, reaction reactors, turbine compressors, submersible motors and other equipment. Their sealing performance and service life depend on many factors, such as selection, machine accuracy, correct installation and use, etc.

[0003] According to the disclosed adjustable clamping fixture for mechanical seal processing (publication number: CN216066452U), in the above application, by setting an adjustment block, when the rotating column is rotated clockwise, the linkage plate drives the four adjustment blocks to push the four connecting rods to move toward one end away from each other, and when the rotating column is rotated counterclockwise, the linkage plate drives the four adjustment blocks to pull the four connecting rods toward one end away from each other. In this way, the positions of the four connecting rods can be adjusted according to the actual size of the mechanical seal to be processed, which meets different needs in the work and greatly improves the practicality.

[0004] The device clamps the mechanical seal through four groups of connecting rods and fixed blocks.

When the other end of the mechanical seal needs to be processed, it is necessary to first release the clamp of the mechanical seal and then manually turn it over, and then use the four groups of connecting rods and fixed blocks to clamp the mechanical seal again, which is too troublesome to operate.

While the worm 63 rotates, the worm wheel 611 meshed with it can drive the rotating rod 62 to rotate on the inner wall of the base 1.

[0034] The above-mentioned stabilizing mechanism 7 includes a boss 71, an arc block 72, a swing rod 73, a suction cup 74, a hollow rod 75, a ball head rod 76, a fixed shaft 77, and a spring 78; the boss 71 is fixedly mounted on the outer wall of the clamping plate 4, the outer wall of the slide plate 2 is fixedly mounted with the arc block 72, the outer wall of the boss 71 is hinged with a swing rod 73, one end of the swing rod 73 is fixedly mounted with a suction cup 74, and the other end of the swing rod 73 is fixedly mounted with a hollow rod 75, and the swing rod 73 is driven to rotate by the hollow rod 75 so that the suction cup 74 can be adsorbed on the outer wall of the mechanical seal, the inner wall of the boss 71 is slidably connected with the ball head rod 76, and the ball head rod 76 passes through the boss 71, and the outer wall of the ball head rod 76 is fixedly mounted with a fixed shaft 77, the outer wall of the fixed shaft 77 is fitted against the inner wall of the hollow rod 75, and the ball head rod 76 slides while cooperating with the fixed shaft 77 and the hollow rod 75 to drive the rocker arm 73 to rotate on the outer wall of the boss 71. One end of the ball head rod 76 is fitted against the outer wall of the arc block 72. When the ball head rod 76 moves to the outer wall of the arc block 72, it will be squeezed by the arc block 72. At this time, the ball head rod 76 will slide into the inside of the boss 71 and compress the spring 78. The other end of the ball head rod 76 is fixedly installed with a spring 78. The end of the spring 78 away from the ball head rod 76 is fixedly installed on the inner wall of the boss 71. The elasticity of the spring 78 can drive the ball head rod 76 to slide and reset on the inner wall of the boss 71.

[0035] The auxiliary mechanism 8 includes an air cylinder 81, an air pipe 82, a piston 83, a push rod 84, a vertical rod 85, and a connecting rod 86; the air cylinder 81 is fixedly mounted on the outer wall of the boss 71, the air pipe 82 is fixedly mounted on the outer wall of the air cylinder 81, the end of the air pipe 82 away from the air cylinder 81 is fixedly mounted on the outer wall of the suction cup 74, the interior of the air cylinder 81 is connected to the interior of the suction cup 74 through the air pipe 82, the inner wall of the air cylinder 81 is slidably connected with the piston 83, the outer wall of the piston 83 is fixedly mounted with a push rod 84, the end of the push rod 84 away from the piston 83 passes through the air cylinder 81 and is fixed A vertical rod 85 is installed, and a push rod 84 is slidably connected to the penetration point of the air cylinder 81. The push rod 84 slides and cooperates with the piston 83 to inject the air inside the air cylinder 81 into the interior of the suction cup 74 through the air pipe 82, or the air inside the suction cup 74 is sucked into the interior of the air cylinder 81 through the air pipe 82. A connecting rod 86 is hinged on the outer wall of the vertical rod 85, and one end of the connecting rod 86 away from the vertical rod 85 is hinged on the outer wall of the fixed shaft 77. When the fixed shaft 77 moves, it cooperates with the vertical rod 85 and the connecting rod 86 to drive the push rod 84 to slide on the inner wall of the air cylinder 81.

[0036] Working principle: first, place the mechanical seal between the two groups of clamping plates 4, then start the cylinder 5 to push the slide plate 2, so that the two groups of slide plates 2 slide synchronously on the inner wall of the base 1 and approach each other, and at the same time, the slide plate 2 will drive the rotating shaft 3 to move synchronously, and the movement of the rotating shaft 3 will drive the clamping plates 4 to move synchronously. At this time, the mechanical seal can be clamped by the two groups of clamping plates 4 close to each other, so as to process the mechanical seal. When one end of the mechanical seal is processed and the other end needs to be processed, the worm 63 is rotated by the knob 612. When the worm 63 rotates, it can drive the worm wheel 611 meshing with it to rotate. When the worm wheel 611 rotates, it will drive the rotating rod 62 to rotate synchronously on the inner wall of the base 1. When the rotating rod 62 rotates, it will drive the rotating disk 69 to rotate synchronously. When the rotating disk 69 rotates, it will drive the eccentric rod 610 to fit in The inner wall of the limiting groove 68 moves, and the eccentric rod 610 pushes the sliding rod 67, so that the sliding rod 67 slides on the inner wall of the base 1. When the sliding rod 67 slides, under the limiting action of the limiting groove 68, the sliding rod 67 pushes the guide rod 66, so that the guide rod 66 drives the slider 61 to slide synchronously on the inner wall of the slide plate 2. When the slider 61 slides, it drives the rack 64 to move synchronously. When the rack 64 moves, it drives the gear 65 meshing with it to rotate. When the gear 65 rotates, it drives the rotating shaft 3 to rotate on the outer wall of the slide plate 2. When the rotating shaft 3 rotates, it drives the splint 4 to rotate synchronously. When the splint 4 rotates, it drives the clamped mechanical seal to rotate synchronously, so that the mechanical seal can be flipped over so that the other end of the mechanical seal can be processed, and there is no need to release the clamping of the mechanical seal, which is more convenient to use.

[0037] When the clamp plate 4 rotates, it will drive the boss 71 to make a circular motion around the rotating shaft 3. At this time, the boss 71 will drive the ball head rod 76 to move synchronously. During the movement of the ball head rod 76, the spring 78 will push the ball head rod 76, so that the ball head rod 76 fits the outer wall of the arc block 72 and moves gradually away from the arc block 72. At the same time, the ball head rod 76 will slide on the inner wall of the boss 71, and the ball head rod 76 will drive the fixed shaft 77 to move synchronously while sliding. When the fixed shaft 77 moves, it will push the hollow rod 75, so that the hollow rod 75 pushes the rocker arm 73, so that the rocker arm 73 rotates on the outer wall of the boss 71. When the rocker arm 73 rotates, it will drive the suction cup 74 to move synchronously, so that the suction cup 74 can be adsorbed on the outer wall of the mechanical seal clamped by the clamp plate 4. The adsorption of the suction cup 74 and the support of the rocker arm 73 can make the mechanical seal more stable during the flipping process, and prevent the mechanical seal from slipping off the clamp plate 4.

[0038] As the fixed shaft 77 pushes the hollow rod 75 so that the rocker arm 73 drives the suction cup 74 to gradually approach the mechanical seal, the fixed shaft 77 will push the connecting rod 86 so that the connecting rod 86 pushes the vertical rod 85. At this time, the vertical rod 85 will push the push rod 84 so that the push rod 84 slides on the inner wall of the air cylinder 81 and gradually slides out of the air cylinder 81. At this time, the push rod 84 will drive the piston 83 to slide synchronously on the inner wall of the air cylinder 81. While the piston 83 slides, the air inside the suction cup 74 will be sucked into the air cylinder 81 through the air pipe 82. When the suction cup 74 is adsorbed on the outer wall of the mechanical seal, the air inside the suction cup 74 is extracted through the air pipe 82 to evacuate the inside of the suction cup 74, so that the suction cup 74 can be more firmly adsorbed on the outer wall of the mechanical seal, thereby improving the adsorption effect of the suction cup 74, thereby further improving the stability of the mechanical seal during the flipping process.

[0039] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
