Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a device for removing burrs from mechanical seals. Background Technology

[0002] Mechanical seals are devices used to prevent fluid leakage. They are typically installed between a rotating shaft and a stationary component and consist of a rotating ring, a stationary ring, a spring, and a sealing ring. During operation, the rotating ring rotates with the shaft, while the stationary ring remains stationary. Under the action of spring force or medium pressure, the end faces of the rotating and stationary rings fit tightly together, forming a tiny gap. This gap ensures the rotation of the shaft while effectively preventing medium leakage. Mechanical seals have advantages such as good sealing performance, long service life, and low frictional power consumption. They are widely used in rotating machinery such as pumps, compressors, and reactors, effectively ensuring the normal operation of equipment and reducing the damage to the environment and equipment caused by medium leakage.

[0003] During the manufacturing process of mechanical seals, defects such as burrs often appear on the surface of the seals due to various factors such as processing technology and mold precision. These burrs not only affect the aesthetics of the seals, but more importantly, they seriously affect their sealing performance. Therefore, a mechanical seal burr removal device is needed to remove the burrs from mechanical seals. However, existing burr removal devices usually use tools such as sandpaper and files for polishing. This method has problems such as low efficiency, high labor intensity, and unstable removal effect. Moreover, existing burr removal devices are not stable enough when clamping the seals, and the seals may loosen or shift during processing, thus affecting the burr removal effect. At the same time, they cannot adapt to seals of different shapes and sizes when removing burrs, which limits the applicability of the device. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5As shown, a mechanical seal burr removal device includes a worktable 1 and a rotary table 2, which are disposed above the worktable 1. A bracket 3 is fixed on the top of the worktable 1, and a drive mechanism 4 for driving the rotary table 2 to rotate is provided on the top of the worktable 1.

[0026] It should be noted that: the worktable 1 serves as the basic support platform for the entire device, providing installation positions for other components and ensuring that each part of the device can be placed stably and operate normally. The rotary table 2 is used to place and fix the mechanical seals. It rotates under the drive mechanism 4, thereby changing the angle of the seals so that the burrs of the seals can be removed at different positions. The bracket 3 is fixedly installed on the top of the worktable 1, providing installation support for components such as the cylinder 5, and playing the role of connecting and fixing other components to ensure that components such as the cylinder 5 can work stably. The drive mechanism 4 can drive the rotary table 2 to rotate through its internal structure.

[0027] Cylinder 5 is installed on the inner wall of bracket 3. The piston rod of cylinder 5 is fixed with push block 6. A first connecting seat 7 is provided on one side of push block 6. A support arm 8 is rotatably connected to the inner wall of the first connecting seat 7. A second connecting seat 9 is rotatably connected to the other end of the support arm 8. A rotating mechanism 10 is provided on the outer side of both the first connecting seat 7 and the second connecting seat 9.

[0028] It should be noted that: Cylinder 5, as the actuator, pushes push block 6 to move through the extension and retraction of the piston rod, thereby driving the support arm 8 and other components to adjust the position of the grinding disc 18, so as to remove burrs from different parts of the seal. Push block 6 connects the piston rod of cylinder 5 and the first connecting seat 7, and moves under the push of cylinder 5, transmitting power and driving the support arm 8 to move, thereby adjusting the position of the grinding disc 18. The first connecting seat 7 serves as the rotation connection point at one end of the support arm 8, and also connects to the rotating mechanism 10, realizing the rotation and angle adjustment of the support arm 8. The support arm 8 is adjusted to change the angle of the grinding disc 18 to better adapt to the needs of removing burrs from the seal. The support arm 8 connects the first connecting seat 7 and the second connecting seat 9, which serve to support and transmit power. By rotating it, the position and angle of the grinding disc 18 can be adjusted so that the grinding disc 18 can accurately remove burrs from the seal. The second connecting seat 9 serves as the rotation connection point at the other end of the support arm 8, and also connects the rotating mechanism 10 and the fixed seat 15 to realize the rotation and angle adjustment of the support arm 8, and provide a foundation for the installation of the grinding disc 18, ensuring that the grinding disc 18 can work stably.

[0029] Meanwhile, cylinder 5 is composed of an air compressor, an air tank, a filter pressure reducing valve, a directional control valve, and a flow control valve. During use, the air compressor compresses ambient air to a set pressure and stores it in the air tank. The filter pressure reducing valve further purifies the air and stabilizes the pressure, then delivers it to the control valve through an air pipe. The directional control valve switches the airflow channel according to an electrical signal to determine the extension and retraction direction of cylinder 5. The flow control valve adjusts the airflow speed to control the movement speed of cylinder 5. Compressed air enters the rodless chamber or rodless cavity of cylinder 5, pushing the piston to move. The piston drives the piston rod to output linear reciprocating motion.

[0030] The movable frame 11 slides on the inner wall of the rotating table 2. A spring 12 is fixed on one side of the movable frame 11, and a clamping block 13 is fixed on one end of the spring 12. Two sets of limiting rods 14 are fixed on the outer side of the clamping block 13, and the outer side of the limiting rods 14 is slidably connected to the inner wall of the movable frame 11.

[0031] It should be noted that: the movable frame 11 slides within the rotary table 2, driving the clamping block 13 to move, realizing the clamping and releasing operation of the mechanical seal, ensuring that the seal can be stably fixed during processing. The spring 12 provides elastic force to the clamping block 13, enabling the clamping block 13 to clamp the seal more tightly, while also acting as a buffer to prevent excessive clamping force from damaging the seal, ensuring the integrity of the seal during processing. The clamping block 13 directly contacts the mechanical seal, realizing the clamping and fixing of the seal, ensuring that the seal will not move or shake during processing, ensuring the accuracy and quality of burr removal. The limit rod 14 restricts the movement direction of the clamping block 13, ensuring that the clamping block 13 moves in a straight line, while preventing the clamping block 13 from deviating or shaking during movement, ensuring the stability and accuracy of clamping.

[0032] The drive mechanism 4 includes a first motor 41 disposed on the top of the worktable 1. A first worm 42 is fixed to the output end of the first motor 41. A first worm wheel 43 is meshed with the outer side of the first worm 42. A vertically arranged rotating shaft 44 is fixed at the axis of the first worm wheel 43, and the top end of the rotating shaft 44 is fixedly connected to the bottom of the rotary table 2.

[0033] It should be noted that: the first motor 41 is the power source that drives the rotary table 2 to rotate, providing the necessary power for the rotation of the rotary table 2. The first worm gear 42 transmits the rotational motion of the first motor 41 to the first worm wheel 43 to realize power transmission. At the same time, the worm gear transmission has a certain speed reduction effect, which can adjust the rotational speed of the rotary table 2. The first worm wheel 43 meshes with the first worm gear 42 and transmits the rotational motion to the rotating shaft 44. The worm gear transmission also has self-locking properties, which can ensure that the rotary table 2 remains stable when it stops rotating and will not easily rotate due to external forces. The rotating shaft 44 connects the first worm wheel 43 and the rotary table 2, and transmits the rotational motion of the first worm wheel 43 to the rotary table 2, driving the rotary table 2 to rotate.

[0034] The rotating mechanism 10 includes two sets of bases 101 respectively fixed to one side of the push block 6 and the second connecting seat 9. A rotating disk 102 is rotatably connected to the outer side of the base 101, and the outer side of the rotating disk 102 is fixedly connected to one side of the first connecting seat 7. A screw 103 is threadedly connected to the inner wall of the rotating disk 102, and a turntable 104 is fixed to one end of the screw 103.

[0035] It should be noted that: the base 101 provides a rotation support point for the rotating disk 102, serving to fix and connect it, enabling the rotating disk 102 to rotate stably. The rotating disk 102 allows the first connecting seat 7 and the second connecting seat 9 to rotate, thereby adjusting the angle of the support arm 8 and fine-tuning the angle of the grinding disk 18 to meet the angle requirements for removing burrs from different seals. The screw 103 is threadedly connected to the rotating disk 102. By rotating the screw 103 through the rotating disk 102 and pressing against the base 101, the position of the rotating disk 102 can be fixed, thereby locking the angle of the support arm 8 and ensuring the angular stability of the grinding disk 18 during operation. The turntable 104 facilitates manual rotation of the screw 103 to fix and adjust the rotating disk 102.

[0036] A fixed base 15 is fixed to the outer side of the rotating disk 102 on one side of the second connecting seat 9. A protective shell 16 is fixed to the inner wall of the fixed base 15. A second motor 17 is installed inside the protective shell 16. A grinding disc 18 is installed at the output end of the second motor 17.

[0037] It should be noted that: the fixed base 15 fixes the protective shell 16, providing an installation position for the second motor 17, and plays a supporting and connecting role to ensure that the second motor 17 can work stably. The protective shell 16 is used to protect the second motor 17 inside, preventing dust, debris, etc. from entering the second motor 17 and affecting its normal operation. The second motor 17 serves as the power source for the grinding disc 18, driving the grinding disc 18 to rotate at high speed to remove burrs from the mechanical seal. The high-speed rotating grinding disc 18 contacts the surface of the seal, grinding away the burrs. The grinding disc 18 performs burr removal processing on the mechanical seal, removing burrs, unevenness, and other defects from the surface of the seal, so that the surface of the seal reaches the required precision and smoothness, thereby improving the quality of the seal.

[0038] The inner wall of the worktable 1 is provided with a ring-shaped limiting groove 19, and the bottom of the rotary table 2 is provided with two sets of rollers 20, and the outer side of the rollers 20 is in rolling connection with the inner wall of the limiting groove 19.

[0039] It should be noted that the limiting groove 19 cooperates with the roller 20 to limit the rotation trajectory of the rotary table 2, ensuring that the rotary table 2 remains stable during rotation, reducing shaking and offset, and ensuring the positional accuracy of the seal during processing. The roller 20 rolls in the limiting groove 19, reducing the friction when the rotary table 2 rotates, making the rotation of the rotary table 2 smoother, and at the same time, it plays a supporting role for the rotary table 2, ensuring that the rotary table 2 can rotate stably.

[0040] The inner wall of the bracket 3 is provided with a sliding groove 21, and two sets of limiting blocks 22 are slidably connected to the inner wall of the sliding groove 21, and one side of the limiting block 22 is fixedly connected to the outer side of the push block 6.

[0041] It should be noted that the sliding groove 21 cooperates with the limiting block 22 to restrict the movement direction of the push block 6, ensuring that the push block 6 moves in a straight line and preventing the push block 6 from deviating or shaking during the movement, thereby ensuring the accuracy of the position adjustment of the grinding disc 18. The limiting block 22 slides in the sliding groove 21 to restrict the movement trajectory of the push block 6, ensuring that the push block 6 moves smoothly. At the same time, it connects the push block 6 to the bracket 3, playing a guiding and supporting role, and ensuring the stability of the position adjustment of the grinding disc 18.

[0042] A third motor 23 is installed on the inner wall of the rotary table 2. A second worm 24 is fixed to the output end of the third motor 23. A second worm wheel 25 is meshed with the outer side of the second worm 24. A positive and negative threaded rod 26 is fixed at the axis of the second worm wheel 25, and the outer side of the positive and negative threaded rod 26 is threadedly connected to the inner wall of the movable frame 11. Two sets of support plates 27 are fixed to the inner wall of the rotary table 2. The inner wall of the support plate 27 is rotatably connected to the inner wall of the positive and negative threaded rod 26. Two sets of sliding rods 28 are fixed to one side of the support plate 27, and the outer side of the sliding rod 28 is slidably connected to the inner wall of the movable frame 11.

[0043] It should be noted that: the third motor 23 serves as the power source for the movement of the movable frame 11, driving the second worm gear 24 to rotate, thereby realizing the automatic movement of the movable frame 11 and adjusting the position of the clamping block 13 to clamp seals of different sizes. The second worm gear 24 transmits the rotational motion of the third motor 23 to the second worm wheel 25, realizing power transmission and deceleration, adjusting the moving speed of the movable frame 11, and ensuring the smoothness of the clamping operation. The second worm wheel 25 meshes with the second worm gear 24, transmitting the rotational motion to the forward and reverse threaded rods 26. At the same time, the worm gear transmission has self-locking properties, which can ensure the stability of the movable frame 11 when it stops and prevent the clamping block 13 from being clamped. 3. Loosening: The positive and negative threaded rod 26, through its positive and negative thread design, drives the two movable frames 11 to move closer or further apart, realizing the clamping and releasing operation of the clamping block 13 on the mechanical seal, adapting to the clamping requirements of seals of different sizes. The support plate 27 is used to support the positive and negative threaded rod 26 and the fixed slide bar 28, providing support and guidance for the movement of the movable frame 11, ensuring the smooth movement of the movable frame 11, and ensuring the accuracy of the clamping operation. The slide bar 28 is slidably connected to the inner wall of the movable frame 11, restricting the rotation of the movable frame 11, ensuring that the movable frame 11 moves in a straight line, improving the stability of the movement of the movable frame 11, and ensuring the accuracy of the movement of the clamping block 13.

[0044] When it is necessary to remove burrs from mechanical seals, the mechanical seal to be processed is first placed on the rotary table 2. Then, the third motor 23 is started, and its output end drives the second worm 24 to rotate. Since the second worm 24 meshes with the second worm wheel 25, the second worm wheel 25 can rotate accordingly, thereby driving the positive and negative threaded rod 26 to rotate. The special thread design of the positive and negative threaded rod 26 causes the two movable frames 11 connected to it to move closer to each other along the slide rod 28. During the movement, the movable frame 11 can push the clamping block 13 to contact the seal. At this time, the spring 12 is compressed. The elastic force generated by the contraction causes the clamping block 13 to tightly clamp the seal. At the same time, the limiting rod 14 ensures that the clamping block 13 moves in a stable direction, preventing the movable frame 11 from shifting. Then, the cylinder 5 is activated, and the piston rod of the cylinder 5 extends and retracts, pushing the push block 6 to move along the slide groove 21 on the inner wall of the bracket 3. Through the cooperation of the slide groove 21 and the limiting block 22, the push block 6 can move smoothly. At this time, the push block 6 drives the first connecting seat 7 to move, thereby causing the support arm 8 to rotate and change position. At the same time, the angle of the grinding disc 18 can be adjusted by the rotating mechanism 10, and the rotation can be done manually. The disc 104 drives the screw 103 to rotate, causing the rotating disc 102 to rotate on the base 101, thereby changing the angle of the first connecting seat 7 and the second connecting seat 9, achieving fine adjustment of the angle of the support arm 8, so that the grinding disc 18 is accurately aligned with the position of the seal that needs to be deburred. Then, the first motor 41 is started, and the output end of the first motor 41 drives the first worm 42 to rotate. Since the first worm 42 and the first worm wheel 43 mesh with each other, the first worm wheel 43 can rotate accordingly. The first worm wheel 43 drives the rotating shaft 44 fixed at its axis to rotate. The top of shaft 44 is fixedly connected to the bottom of the rotary table 2, so that the rotating shaft 44 can drive the rotary table 2 to rotate. The roller 20 at the bottom of the rotary table 2 rolls in the annular limiting groove 19 on the inner wall of the worktable 1, which reduces friction and ensures that the rotary table 2 rotates smoothly, so that different parts of the seal rotate to the bottom of the grinding disc 18 in sequence. Finally, the second motor 17 is started. The output end of the second motor 17 drives the grinding disc 18 to rotate at high speed. The high-speed rotating grinding disc 18 contacts the surface of the seal and grinds off the burrs on the surface of the seal, thus realizing the removal of burrs from the seal.
