Abstract
Description
Technical Field
[0001] This utility model relates to the field of sealing ring production technology, specifically a center positioning mechanism for sealing ring production. Background Technology
[0002] A sealing ring is a mechanical part used to prevent fluid (liquid or gas) leakage and to block the entry of impurities such as dust and dirt. Metal sealing rings are often used in special working conditions such as high temperature, high pressure, and high vacuum. They are made of materials such as stainless steel and copper alloys. Metal sealing rings have advantages such as high strength, high temperature resistance, and wear resistance, but they are also more expensive and more difficult to process.
[0003] Existing metal sealing rings require grinding of their outer rings during production. Grinding the outer ring of the sealing ring is an important process for processing or repairing the sealing ring, which can improve its dimensional accuracy, surface quality and sealing performance. Existing sealing rings are generally clamped and positioned by clamping plates during grinding. Since the clamping plates include the outer surface of the metal sealing ring, grinding is inconvenient. In view of this, a center positioning mechanism for sealing ring production is proposed. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a center positioning mechanism for sealing ring production, which solves the problem of inconvenient sealing ring positioning.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a center positioning mechanism for sealing ring production, including a base, wherein four first sliding grooves are formed on the upper surface of the base;
[0006] The base is equipped with a positioning mechanism, which includes a motor, worm gear, worm wheel, lead screw, collar, limit plate, support rod, T-shaped plate, second slide groove, bidirectional threaded rod, knob, moving block, anti-slip pad, and groove.
[0007] Preferably, the motor is fixedly installed in the inner wall of the base, and the worm gear is fixedly installed at the output end of the motor;
[0008] The worm gear is meshed with the outer surface of the worm.
[0009] Preferably, the lead screw is fixedly sleeved on the inner surface of the worm gear, and the collar is threadedly sleeved on the outer surface of the lead screw;
[0010] Eight support rods are rotatably connected to the outer surface of the collar.
[0011] Preferably, the four T-shaped plates are rotatably connected to the ends of the eight support rods away from the collar, and the vertical plates of the four T-shaped plates are slidably connected to the four first sliding grooves respectively.
[0012] The four second grooves are located on the opposite side of the four T-shaped plates.
[0013] Preferably, the lower ends of the four bidirectional threaded rods are rotatably connected to the inner walls of the four second sliding grooves, and the upper ends of the four bidirectional threaded rods penetrate the upper surfaces of the four T-shaped vertical plates.
[0014] The four knobs are fixedly installed on the upper ends of the four bidirectional threaded rods.
[0015] Preferably, the eight movable blocks are respectively threaded onto the outer surface of the four bidirectional threaded rods, and the eight movable blocks are respectively slidably connected to the four second sliding grooves.
[0016] Preferably, the eight anti-slip pads are fixedly installed on the opposite sides of the eight movable blocks, and the grooves are respectively formed on the opposite sides of the eight anti-slip pads.
[0017] Compared with the prior art, this utility model provides a center positioning mechanism for sealing ring production, which has the following advantages:
[0018] 1. The center positioning mechanism for the production of this sealing ring uses a motor to drive the T-shaped plate to move towards the opposite side to fix the sealing ring in an inner circle. Furthermore, the self-locking property of the worm gear and worm can be used to make the sealing ring of the positioning component more stable.
[0019] 2. The center positioning mechanism used in the production of this sealing ring uses the up-and-down movement of the moving block to drive the anti-slip pad to achieve the vertical positioning and clamping action of the sealing element. According to different sealing element thicknesses and heights, it can be precisely adjusted to the appropriate position. Furthermore, the groove allows the sealing element to be better fixed and accommodated during the positioning process, preventing the sealing element from shifting during processing and ensuring that the sealing element is in a precise center position, thereby guaranteeing processing accuracy.

[0025] 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.
[0026] Please see Figure 1-4 This utility model provides a new technical solution: a center positioning mechanism for sealing ring production, including a base 1, and four first sliding grooves 2 are provided on the upper surface of the base 1;
[0027] The base 1 is equipped with a positioning mechanism, which includes a motor 3, a worm gear 4, a worm wheel 5, a lead screw 6, a collar 7, a limiting plate 8, a support rod 9, a T-shaped plate 10, a second sliding groove 11, a bidirectional threaded rod 12, a knob 13, a moving block 14, an anti-slip pad 15, and a groove 16.
[0028] Furthermore, the motor 3 is fixedly installed in the inner wall of the base 1, and the worm gear 4 is fixedly installed at the output end of the motor 3;
[0029] The worm gear 5 is meshed with the outer surface of the worm 4.
[0030] Furthermore, the lead screw 6 is fixedly sleeved on the inner surface of the worm gear 5, and the collar 7 is threadedly sleeved on the outer surface of the lead screw 6;
[0031] Among them, eight support rods 9 are rotatably connected to the outer surface of the collar 7.
[0032] Furthermore, the four T-shaped plates 10 are rotatably connected to the ends of the eight support rods 9 away from the collar 7, and the vertical plates of the four T-shaped plates 10 are slidably connected to the four first sliding grooves 2 respectively.
[0033] Among them, four second grooves 11 are opened on the opposite side of the four T-shaped plates 10.
[0034] Furthermore, the lower ends of the four bidirectional threaded rods 12 are rotatably connected to the inner walls of the four second sliding grooves 11, and the upper ends of the four bidirectional threaded rods 12 pass through the upper surfaces of the vertical plates of the four T-shaped plates 10.
[0035] The four knobs 13 are respectively fixedly installed on the upper ends of the four bidirectional threaded rods 12.
[0036] Furthermore, eight movable blocks 14 are respectively threaded onto the outer surfaces of four bidirectional threaded rods 12, and the eight movable blocks 14 are respectively slidably connected to four second sliding grooves 11.
[0037] Furthermore, eight anti-slip pads 15 are respectively fixedly installed on the opposite sides of eight movable blocks 14, and grooves 16 are respectively opened on the opposite sides of the eight anti-slip pads 15.
[0038] When using the center positioning mechanism for sealing ring production, the sealing ring is placed on the outer surface of four T-shaped plates 10. The motor 3 is then started, and its operation outputs power to the worm gear 4 fixedly mounted at the output end, causing it to rotate. The worm gear 4 drives the worm wheel 5, which is meshed with the outer surface, to rotate. The worm wheel 5, in turn, drives the lead screw 6, which is fixed on the inner surface, to rotate. Simultaneously, the collar 7 threaded onto the outer surface of the lead screw 6 moves downwards through the threads on its outer surface. At the same time, the lead screw 6 drives the eight support rods 9, which are rotatably connected to the outer surface, to move downwards. As the eight support rods 9 move downwards and become fixed, they gradually become horizontal. At this point, the eight support rods 9 are rotatably connected to the T-shaped plates at opposite ends. Plate 10 applies a thrust from the opposite side, causing the vertical plate of T-shaped plate 10 to move towards the opposite side within the inner walls of the four first sliding grooves 2, thus fixing the sealing ring in an inner supporting circle. At this time, by rotating knob 13, knob 13 drives the bidirectional threaded rod 12 fixedly installed on the lower surface to rotate. At this time, the moving block 14 threaded on the outer surface of the bidirectional threaded rod 12 continuously moves towards the opposite side through the thread provided on the outer surface of the bidirectional threaded rod 12. At this time, the anti-slip pads 15 fixedly installed on the opposite sides of the two moving blocks 14 contact the upper and lower surfaces of the sealing ring to clamp and fix it. The groove 16 can prevent the seal from shifting position during processing, ensuring that the seal is in a precise center position. At this time, the sealing ring can be processed.
[0039] The center positioning mechanism for producing this sealing ring uses a motor 3 to drive the T-shaped plate 10 to move towards the opposite side to fix the sealing ring in an inner circle. The self-locking property of the worm gear and worm ensures a more stable fixation of the sealing ring. The center positioning mechanism, through the up-and-down movement of the moving block 14, drives the anti-slip pad 15 to achieve vertical positioning and clamping of the sealing element. It can be precisely adjusted to the appropriate position according to different sealing element thicknesses and heights. The groove 16 ensures better fixation and containment of the sealing element during positioning, preventing positional shifts and ensuring the sealing element is precisely centered, thus guaranteeing processing accuracy.
[0040] Structural Description:
[0041] Base 1: This is the basic support component of the entire mechanism, providing a mounting location for other components.
[0042] First slide 2: The first slide 2 is used to provide a sliding track for the vertical plate part of the T-shaped plate 10, so that the T-shaped plate 10 can move in translation on the upper surface of the base 1, providing a planar constraint path for the unfolding and retracting action of the entire positioning mechanism.
[0043] Motor 3: Fixedly installed in the inner wall of base 1, serving as a power source, driving worm 4 to rotate through its output end. The rotation speed and direction of the motor can be adjusted by an external control system, thereby controlling the action rhythm and adjustment direction of the entire positioning mechanism.
[0044] Worm 4: Fixedly installed at the output end of motor 3. When motor 3 rotates, it drives worm 4 to rotate together. Its main function is to transmit the rotational power of the motor to the worm wheel 5 that meshes with it. It can also achieve the effect of speed reduction and torque increase through its own spiral structure and the cooperation of worm wheel 5 to meet the torque requirements of the positioning mechanism.
[0045] Worm Gear 5: It is meshed with the outer surface of the worm 4. Due to the transmission ratio characteristics of the worm 4 and worm gear 5, when the worm 4 rotates, it drives the worm gear 5 to rotate. The worm gear 5 can convert the rotational motion from the motor 3 and the worm 4 into a rotational motion with greater torque, providing stable and sufficient power for subsequent components. The lead screw 6 is fixedly sleeved inside it, and it transmits its own rotational motion to the lead screw 6.
[0046] Lead screw 6: A collar 7 is threaded on the outer surface of the lead screw 6. The rotational motion of the lead screw 6 is converted into the linear motion of the collar 7. The lead screw 6 generally has high-precision threads, which can ensure that the linear motion of the collar 7 has high precision, providing a basis for the precise adjustment of the entire positioning mechanism.
[0047] Collar 7: When the lead screw 6 rotates, the collar 7 will move linearly along the lead screw 6. Its outer surface is rotatably connected to eight support rods 9. The linear movement of the collar 7 will drive the T-shaped plate 10 to adjust its position through the support rods 9, thereby realizing the extension and retraction of the entire positioning mechanism and changing the range of the positioning mechanism.
[0048] Support rod 9: Converts the linear motion of collar 7 into the translational motion of T-shaped plate 10. Through the rotational connection of support rod 9, the T-shaped plate 10 can flexibly change its position in the horizontal direction, thereby changing the relative position and spacing between the four T-shaped plates 10 to achieve the purpose of adjusting the positioning range.
[0049] T-shaped plate 10: The shape design of the T-shaped plate 10 allows it to slide stably on the base 1 and its position can be adjusted by the transmission of the support rod 9, ultimately providing horizontal positioning support for the seal.
[0050] The second slide groove 11 provides a rotatable connection position for the lower end of the bidirectional threaded rod 12, and also provides a sliding track for the eight moving blocks 14, ensuring that the moving blocks 14 move linearly in the direction perpendicular to the movement direction of the T-shaped plate 10, and limiting the range of movement of the moving blocks 14 so that they can only slide up and down within the second slide groove 11.
[0051] Bidirectional threaded rod 12: The bidirectional threaded rod 12 is a key component for vertical positioning and adjustment of the seal. By rotating the bidirectional threaded rod 12, the moving block 14 sleeved on its outer surface can be moved up and down to achieve positioning and adjustment at different heights. The bidirectional threaded rod 12 can drive the moving block 14 in both positive and negative directions, giving it bidirectional adjustment capability.
[0052] Knob 13: Facilitates manual operation of the bidirectional threaded rod 12. Rotating the knob 13 drives the bidirectional threaded rod 12 to rotate, providing a convenient operating point for manual adjustment. The operator can manually adjust the rotation amount of the bidirectional threaded rod 12 according to the actual size and positioning requirements of the seal, thereby controlling the up and down position of the moving block 14.
[0053] Moving block 14: Moving block 14 slides up and down in the second slide groove 11 as the bidirectional threaded rod 12 rotates. The up and down movement of moving block 14 drives the anti-slip pad 15 to achieve the vertical positioning and clamping action of the seal. It can be precisely adjusted to the appropriate position according to different seal thicknesses and heights.
[0054] Anti-slip pad 15: Provides direct contact and support for the seal. The anti-slip pad 15 can increase the friction with the seal, prevent the seal from sliding during positioning, ensure the stability of the seal's position during processing, and improve the accuracy and reliability of positioning.
[0055] Groove 16: Groove 16 is designed to better fit the shape of the seal, so that the seal can be better fixed and accommodated during the positioning process, avoid the seal from shifting position during processing, and ensure that the seal is in a precise center position, thereby guaranteeing processing accuracy.
[0056] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
