Description

Technical Field

[0001] The invention belongs to the field of equipment assembly, and particularly relates to an inner hole sealing ring assembly device and a use method. Background Art

[0002] In industrial automation equipment, sealing rings, as key sealing components, are widely used in static sealing, reciprocating motion sealing, and low-speed rotary sealing. Their primary function is to prevent fluid or gas leakage and ensure a stable internal environment, playing a crucial role in ensuring the proper operation of industrial automation equipment. However, in actual use, as equipment operates over time, friction inevitably arises between the sealing ring and moving parts. This constant friction causes the sealing ring to gradually wear, weakening its sealing performance and potentially even causing leakage. To restore the sealing performance of the equipment, the worn sealing ring typically needs to be replaced.

[0003] During equipment maintenance, the assembly of the inner bore sealing ring is a particularly critical step. However, existing methods for assembling inner bore sealing rings have numerous shortcomings, being cumbersome and difficult to master. Due to a lack of effective auxiliary tools or methods, maintenance personnel struggle to precisely control the installation position and force of the sealing ring during assembly. This can easily lead to defects such as deformation or gaps in the sealing ring during assembly, resulting in unsatisfactory assembly results. These defects not only affect the sealing performance of the sealing ring but can also shorten its service life, causing significant inconvenience to maintenance work and reducing work efficiency. Summary of the Invention

[0007] In a possible implementation of the first aspect, fourth threaded holes are formed on the fourth slat near both ends; After the fourth threaded holes near the two ends of the fourth slat are aligned with the corresponding first threaded holes and second threaded holes on the first slat and the second slat, screws are used to connect the fourth slat with the first slat and the second slat.

[0008] In a possible implementation manner of the first aspect, the plurality of first threaded holes on the first slats are evenly distributed.

[0009] In a possible implementation of the first aspect, fifth threaded holes are formed on the fifth slat near both ends. After the fifth threaded holes near the two ends of the fifth slat are aligned with the corresponding first threaded holes and second threaded holes on the first slat and the second slat, screws are used to connect the fifth slat with the first slat and the second slat.

[0010] In a possible implementation manner of the first aspect, the plurality of second threaded holes on the second strip are evenly distributed.

[0011] In a possible implementation of the first aspect, a sixth threaded hole is formed in the middle of the fourth strip; One end of the first latch is provided with a first threaded head that cooperates with the sixth threaded hole.

DETAILED DESCRIPTION

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0021] Combine Figures 1 to 6 As shown, the specific implementation methods of the present invention are described in detail below in combination with the inner hole sealing ring assembly device and the use method thereof provided by the present invention, so that those skilled in the art can better understand and implement the present invention.

[0022] like Figure 1 As shown, the assembly of the inner hole sealing ring assembly device specifically involves the following steps: prepare a first plate 1, a second plate 2, a third plate 3, a fourth plate 4, and a fifth plate 5. Align the ends of the third plate 3 with the center of the first and second plates 1 and 2, respectively. Third threaded holes 31 are provided near the ends of the third plate 3. From the center toward the ends, a plurality of first threaded holes 10 and second threaded holes 20 are provided on the first and second plates 1 and 2, respectively. Appropriate first threaded holes 10 and second threaded holes 20 are selected so that they align with the third threaded holes 31. Then, screws are used to connect the third plate 3 to the first and second plates 1 and 2. The fourth and fifth plates 4 and 5 are located on either side of the third plate 3, respectively, and their distance from the third plate 3 is adjustable. Fourth threaded holes 40 and fifth threaded holes 50 are provided near the ends of the fourth and fifth plates 4 and 5, respectively. Similarly, select appropriate first threaded holes 10 and second threaded holes 20 so that they are aligned with fourth threaded holes 40 and fifth threaded holes 50, and then use screws to connect fourth slat 4 and fifth slat 5 to first slat 1 and second slat 2, respectively.

[0023] A sixth threaded hole 41 is defined in the middle of the fourth slat 4. A first threaded head 60 is provided at one end of the first latch 6 to mate with the sixth threaded hole 41, and the first latch 6 is vertically mounted on the fourth slat 4 via a threaded connection. Similarly, a seventh threaded hole 51 is defined in the middle of the fifth slat 5. A second threaded head 70 is provided at one end of the second latch 7 to mate with the seventh threaded hole 51, and the second latch 7 is vertically mounted on the fifth slat 5 via a threaded connection. The third latch 8 is slidably mounted within the elongated hole 30 of the third slat 3. No additional securing measures are required; simply ensure that the third latch 8 can slide freely within the elongated hole 30.

[0024] Adjust the positions of the fourth and fifth strips 4 and 5 based on the inner hole diameter and the thickness of the inner hole sealing ring. Specifically, the distance between the outer sides of the fourth and fifth strips 4 and 5 should be no greater than the inner hole diameter minus twice the thickness of the inner hole sealing ring. This step ensures that the inner hole sealing ring is properly stretched when fitted over the first and second latches 6 and 7, allowing it to be inserted into the inner hole.

[0025] After adjusting the positions of the fourth slat 4 and the fifth slat 5, use screws to fix the fourth slat 4 and the fifth slat 5 to the first slat 1 and the second slat 2 respectively to ensure that the positions of the fourth slat 4 and the fifth slat 5 will not change during the assembly process.

[0026] The inner hole sealing ring to be assembled is sleeved on the first latch 6 and the second latch 7. Since the cylindrical surfaces of the first latch 6 and the second latch 7 are smooth surfaces, the sealing ring can be easily sleeved on them, and the sealing ring will be properly stretched.

[0027] The third latch 8 is controlled to slide up or down along the elongated hole 30. During this sliding process, the third latch 8, together with the first and second latches 6 and 7, exerts a force on the inner hole sealing ring, causing it to form a concave shape. This operation facilitates the sealing ring's entry into the inner hole and reduces friction with the inner hole wall during assembly.

[0028] Use the first, second, and third latches 6, 7, and 8 to insert the inner bore sealing ring into the inner bore. Once the inner bore sealing ring is fully inserted, remove the third latch 8. Then, remove the first and second latches 6, 7. During this process, use your hands or another tool to hold the inner bore sealing ring in place to prevent it from being pulled out of the inner bore. After removing the latches, check that the sealing ring is properly installed and undamaged.

[0029] Through the description of the above specific embodiments, those skilled in the art can clearly understand the inner hole sealing ring assembly device and the use method thereof of the present invention, and can make corresponding adjustments and optimizations according to actual needs.

[0030] In one embodiment, the first and second strips 1 and 2 are rectangular metal plates with seven circular holes of equal size evenly spaced on their surfaces (i.e., first threaded holes 10 on the first strip 1 and second threaded holes 20 on the second strip 2). The first threaded holes 10 and second threaded holes 20 are standard metric threaded holes, and the first threaded holes 10 on the first strip 1 and the second threaded holes 20 on the second strip 2 are symmetrically arranged. The fourth and fifth strips 4 and 5 are rectangular metal plates with three circular holes on their surfaces (i.e., fourth threaded holes 40 near the ends and sixth threaded holes 41 in the middle of the fourth strip 4, and fifth threaded holes 50 near the ends and seventh threaded holes 51 in the middle of the fifth strip 5). The fourth threaded holes 40, sixth threaded holes 41, fifth threaded holes 50, and seventh threaded holes 51 are standard metric threaded holes, and the first threaded holes 10, second threaded holes 20, fourth threaded holes 40, sixth threaded holes 41, fifth threaded holes 50, and seventh threaded holes 51 are standard M6 threaded holes. The first, second, third, fourth, and fifth strips 1, 2, 3, 4, and 5 are all identical in shape and size, measuring 300 mm in length, 5 mm in width, and 20 mm in height. The elongated hole 30 in the third strip 3 is located in the center of the metal plate, measuring 240 mm in length and 8 mm in height. This is larger than the diameter of the third latch 8, allowing it to move within the elongated hole 30. The ends of the third strip 3 are provided with third threaded holes 31, both of standard M6 thread size. The first and second latches 6, 7, respectively, have first and second threaded heads 60, 70 at one end, each with standard M6 threads. Their lengths are the same as the widths of the fourth and fifth strips 4, 5. The first, second, and third latches 6, 7, and 8 are all cylindrical metal latches, each with a diameter of 7 mm and a length of 50 mm. The screws are full-thread standard metric M6 screws, which are used to fix the fourth slat 4 to the first slat 1 and the second slat 2, and the fifth slat 5 to the first slat 1 and the second slat 2. The selected screw thread length is greater than or equal to the width of the two overlapping rectangular metal plates, that is, greater than or equal to 10 mm.
