Description

Technical Field

[0001] The utility model relates to the technical field of integrated brake control systems, in particular to a sealing ring installation device of the integrated brake control system. Background Art

[0002] Components such as the connecting rod of an integrated brake control system (IBC) require seals. To ensure accurate delivery of the seals, a hollow guide rail is typically used to position the seals. Cylinders and other components then push the seals into their intended installation position.

[0003] The existing technology uses guide rails with unprocessed inner holes, which are used directly to guide the sealing rings. This can easily cause the sealing rings to become stuck while traveling along the guide rail inner holes. To address this problem, the existing method is to spray a large amount of oil into the guide rails. However, excessive oil injection not only increases costs but also pollutes the equipment.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present invention, and therefore may include information that does not constitute prior art known to ordinary technicians in this field. Utility Model Content

[0005] In view of this, the utility model provides a sealing ring installation device for an integrated brake control system, which can provide reliable guidance for the installation of the sealing ring, avoid the sealing ring from getting stuck, improve the qualified rate of the sealing ring installation, and avoid large amounts of oil spraying and contaminating the equipment.

[0006] According to one aspect of the utility model, a sealing ring installation device for an integrated brake control system is provided, comprising: a hollow guide tube, the inner wall of the guide tube being provided with honing grooves, the gaps between the honing grooves being filled with lubricating oil; a sealing ring clamp having a tubular profile that can be inserted into the guide tube, the sealing ring clamp being capable of tightening and loosening the sealing ring; and a driving mechanism having a push rod that can be inserted into the guide tube.

[0007] The utility model adopts honing technology to form honing grooves on the inner wall of the guide tube, effectively reducing the friction between the sealing ring and the guide tube, providing a reliable guide for the installation of the sealing ring, preventing the sealing ring from getting stuck, and improving the qualified installation rate of the sealing ring. The regular patterns formed by the honing grooves can ensure that the sealing ring is evenly stressed during its movement within the guide tube, avoiding local deformation. The regular patterns formed by the honing grooves can also realize an oil storage function, allowing lubricating oil to fill the gaps between the honing grooves, thereby increasing the lubrication effect, reducing lubricating oil usage, and avoiding equipment contamination. Through the driving mechanism and the sealing ring clamp, the sealing ring is tensioned and accurately pushed to the target installation position. Then, the sealing ring clamp releases the sealing ring, allowing the sealing ring to spring into the target product by its own elastic force.

[0008] In some embodiments, the sealing ring installation device has a sealing ring pushing state and a sealing ring installation state; in the sealing ring pushing state, the push rod pushes the sealing ring clamp to move along the inner wall of the guide tube, and the sealing ring clamp tightens the sealing ring; in the sealing ring installation state, the sealing ring clamp extends out of the guide tube and releases the sealing ring, and the sealing ring bounces off the sealing ring clamp.

[0009] During the installation process of the sealing ring, the sealing ring is first tensioned by the sealing ring clamp, and the push rod pushes the sealing ring clamp along the inner wall of the guide tube, so that the sealing ring accurately reaches the target installation position; when the sealing ring clamp extends out of the guide tube and the sealing ring reaches the target installation position, the sealing ring clamp releases the sealing ring, so that the sealing ring relies on its own elastic force to bounce into the target product.

[0010] In some embodiments, the sealing ring clamp includes a first notch and a second notch formed at the end, the first notch and the second notch are symmetrical in the radial direction and staggered in the axial direction, and are movably connected in the axial direction; when the sealing ring is pushed, the first notch and the second notch tighten the sealing ring; when the sealing ring is installed, the first notch and the second notch move toward each other along the axial direction to loosen the sealing ring.

[0011] The first and second notches are radially symmetrical and axially staggered, tilting and spreading the sealing ring so that it can at least partially spring into the target product when released. When the sealing ring is advanced, the first and second notches tension the sealing ring until it extends out of the guide tube. When the sealing ring is installed, the first and second notches move axially toward each other to release the sealing ring, allowing it to at least partially spring into the target product axially due to its own elastic force.

[0012] In some embodiments, the sealing ring clamp includes a main body and an end portion, the first notch and the second notch are respectively formed in the main body and the end portion, and the main body and the end portion are movably connected through an elastic member and / or a telescopic member.

[0013] The elastic member and / or the telescopic member are used to realize an axially movable connection between the main body and the end portion, thereby enabling the first notch and the second notch to tighten and loosen the sealing ring.

[0014] In some embodiments, the end portion includes an end piece and a connecting portion, the connecting portion can be movably extended into the main body portion, and the end piece and the main body portion are connected by a spring.

[0015] The connecting portion can be movably extended into the main body portion, and the end piece and the main body portion are connected via a spring, so that the first notch and the second notch can be movably connected in the axial direction to tighten and loosen the sealing ring.

[0016] In some embodiments, the connecting portion and the main body portion are clearance-fitted and provided with a snap-fit ​​structure; when the sealing ring is in the advanced state, the snap-fit ​​structure is engaged; when the sealing ring is in the installed state, the spring is compressed and the snap-fit ​​structure is disengaged.

[0017] When the sealing ring is pushed, the snap structure is engaged, so that the relative position between the end portion and the main body is kept fixed, so that the sealing ring is stably tensioned; when the sealing ring reaches the target installation position, for example, the sealing ring clamp is pushed to abut against the target product with a certain force, the spring is compressed, and the snap structure is disengaged, so that the first notch and the second notch move axially toward each other, so that the sealing ring is loosened and bounces into the target product by its own elastic force.

[0018] In some embodiments, the snap-fit ​​structure includes an arc-shaped protrusion and an arc-shaped groove formed on the connecting portion and the main body portion respectively.

[0019] The arc-shaped protrusion cooperates with the arc-shaped groove to facilitate the disengagement of the snap structure when the sealing ring is installed, so that the sealing ring is loosened.

[0020] In some embodiments, the guide tube is a steel tube.

[0021] The steel pipe has strong structural strength and low cost, and can achieve better guiding effect for the installation of the sealing ring.

[0022] In some embodiments, the driving mechanism is a cylinder.

[0023] Through the cylinder, precise and efficient propulsion is achieved.

[0024] In some embodiments, the guide tube and the drive mechanism are both mounted on a mounting bracket.

[0025] In this way, the guide tube and the drive mechanism are stably installed.

[0026] Compared with the prior art, the beneficial effects of the present invention include at least:

[0027] This utility model uses honing technology to form honing grooves on the inner wall of the guide tube, effectively reducing friction between the sealing ring and the guide tube, providing reliable guidance for the installation of the sealing ring, preventing the sealing ring from getting stuck, and improving the qualified installation rate of the sealing ring. The regular patterns formed by the honing grooves ensure that the sealing ring is evenly stressed during its movement within the guide tube, avoiding local deformation. The regular patterns formed by the honing grooves also realize an oil storage function, allowing lubricating oil to fill the gaps between the honing grooves, increasing the lubrication effect, reducing lubricating oil usage, and avoiding equipment contamination. In addition, the utility model uses a driving mechanism and a sealing ring clamp to tension the sealing ring and accurately push it to the target installation position. The sealing ring clamp then releases the sealing ring, allowing the sealing ring to spring into the target product by its own elastic force.

[0028] The sealing ring installation device of the utility model can improve the qualified rate of sealing ring installation from the original 72% to above 99.92% after testing.

[0029] The sealing ring installation device of the present invention is particularly suitable for the installation of dynamic sealing rings with sealing lips, such as the installation of sealing rings of connecting rods of integrated brake control systems. The honing grooves formed on the inner wall of the guide tube can be used to provide a stable guide for the installation of the sealing ring, thereby avoiding deformation of the sealing lip. The sealing ring clamp and the driving mechanism can be used to achieve accurate installation of the sealing ring.

[0036] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to make this disclosure more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art.

[0037] The accompanying drawings are only schematic diagrams of the present invention and are not necessarily drawn to scale. The same reference numerals in the drawings represent the same or similar structures, and their repeated description will be omitted.

[0038] The terms "first," "second," and similar terms used in the specific description do not indicate any order, quantity, or importance, but are simply used to distinguish different components. In the description of this utility model, when a device is said to be "connected" to another device, this includes not only direct connection but also indirect connection through other elements.

[0039] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in different embodiments may be combined with each other.

[0040] Figure 1 The structure of the sealing ring installation device in the embodiment of the utility model is shown; Figure 1 As shown, the sealing ring installation device of the integrated brake control system provided by the embodiment of the present invention includes:

[0041] A hollow guide tube 10, the inner wall of which is provided with honing grooves, and the gaps between the honing grooves are filled with lubricating oil;

[0042] The sealing ring clamp 20 has a tubular profile that can be inserted into the guide tube 10. The sealing ring clamp 20 can tighten and loosen the sealing ring;

[0043] The driving mechanism 30 has a push rod that can extend into the guide tube 10 .

[0044] Honing is a grinding process that uses a honing bar to rub along a specific path on the surface of a metal workpiece, producing a specific geometric shape and improving the surface texture. The present invention utilizes honing technology to form honing grooves on the inner wall of the guide tube 10, effectively reducing friction between the seal ring and the guide tube 10. This provides reliable guidance for the seal ring's installation, prevents the seal ring from getting stuck, and improves the seal ring's installation qualification rate. The regular patterns formed by the honing grooves ensure that the seal ring is evenly stressed during its movement within the guide tube 10, preventing localized deformation. The regular patterns formed by the honing grooves also provide an oil storage function, allowing lubricating oil to fill the gaps between the honing grooves, increasing lubrication effectiveness, reducing lubricating oil usage, and avoiding equipment contamination. The drive mechanism 30 and the seal ring fixture 20 tighten the seal ring and accurately push it to the target installation position. The seal ring fixture 20 then releases the seal ring, allowing it to spring into the target product under its own elastic force.

[0045] Figure 2 and Figure 3 The figure shows the comparison of the lines on the inner wall of the guide tube before and after honing. Figure 2 and Figure 3 Produced by a scanning electron microscope (SEM). Figure 2 As shown, before honing the inner wall of the guide tube, the lines 10a are messy and the resistance is large; Figure 3 As shown, after honing the inner wall of the guide tube, the lines 10b are regular and orderly, and the smoothness and oil storage and lubrication effect are significantly improved, which can effectively reduce the resistance to the sealing ring fixture and the sealing ring, so that the friction and force of the sealing ring are uniform during the movement of the guide tube, thereby improving the guide reliability and reducing the probability of sealing ring installation failure.

[0046] Continue to refer to Figure 1 As shown, in some embodiments, the sealing ring installation device has a sealing ring pushing state and a sealing ring installation state; in the sealing ring pushing state, the push rod pushes the sealing ring clamp 20 to move along the inner wall of the guide tube 10, and the sealing ring clamp 20 tightens the sealing ring; in the sealing ring installation state, the sealing ring clamp 20 extends out of the guide tube 10 and releases the sealing ring, and the sealing ring bounces off the sealing ring clamp 20.

[0047] During the installation of the sealing ring, the sealing ring is first tightened by the sealing ring clamp 20, and the push rod pushes the sealing ring clamp 20 to move along the inner wall of the guide tube 10, so that the sealing ring accurately reaches the target installation position; when the sealing ring clamp 20 extends out of the guide tube 10 and the sealing ring reaches the target installation position, the sealing ring clamp 20 releases the sealing ring, so that the sealing ring relies on its own elastic force to bounce into the target product.

[0048] The target product is, for example, a connecting rod of an integrated brake control system, and the target installation position is, for example, the sealing ring clamp 20 abutting against the connecting rod.

[0049] Figure 4 The structure of the sealing ring clamp in the embodiment of the utility model is shown; Figure 1 and Figure 4 As shown, in some embodiments, the sealing ring clamp 20 includes a first notch 20a and a second notch 20b formed at the end, the first notch 20a and the second notch 20b are symmetrical in the radial direction and staggered in the axial direction Z, and are movably connected in the axial direction Z; when the sealing ring is pushed, the first notch 20a and the second notch 20b tension the sealing ring; when the sealing ring is installed, the first notch 20a and the second notch 20b move toward each other along the axial direction Z to loosen the sealing ring.

[0050] The first notch 20a and the second notch 20b are radially symmetrical and staggered in the axial direction Z, tilting and stretching the sealing ring so that it can at least partially spring into the target product when released. When the sealing ring is advanced, the first notch 20a and the second notch 20b tension the sealing ring until it extends out of the guide tube 10. When the sealing ring is installed, the first notch 20a and the second notch 20b move toward each other in the axial direction Z to release the sealing ring, allowing the sealing ring to at least partially spring into the target product in the axial direction Z due to its own elastic force. Subsequently, when the target product leaves, the sealing ring, which has at least partially entered the sealing ring installation groove, is removed, completing the installation of the sealing ring.

[0051] In some embodiments, the sealing ring clamp 20 includes a main body 21 and an end portion 22, a first notch 20a and a second notch 20b are respectively formed in the main body 21 and the end portion 22, and the main body 21 and the end portion 22 are movably connected through an elastic member and / or a telescopic member.

[0052] The elastic member and / or the telescopic member realizes a movable connection between the main body 21 and the end head 22 in the axial direction Z, thereby enabling the first notch 20a and the second notch 20b to tighten and loosen the sealing ring.

[0053] When the seal ring is advanced, the elastic / telescopic member can be fixed in relative position by a limiting structure. Alternatively, because the inner wall of the guide tube 10 is provided with honing grooves and the gaps between the honing grooves are filled with lubricating oil, the inner wall of the guide tube 10 has low resistance and high lubricity. The movement of the seal ring fixture 20 along the inner wall of the guide tube 10 does not cause axial Z movement of the elastic / telescopic member, thus maintaining the seal ring tension. When the seal ring is installed, the push rod pushes the seal ring fixture 20 until it contacts the target product with a certain force, triggering axial Z movement of the elastic / telescopic member, causing the seal ring to release and automatically eject.

[0054] In some embodiments, the end portion 22 includes an end piece 221 and a connecting portion 222 . The connecting portion 222 can movably extend into the main body 21 . The end piece 221 and the main body 21 are connected via a spring.

[0055] The connecting portion 222 movably extends into the main body 21 , and the end piece 221 is connected to the main body 21 via a spring, so that the first notch 20a and the second notch 20b are movably connected in the axial direction Z to tighten and loosen the sealing ring.

[0056] In some embodiments, the connection portion 222 and the main body portion 21 are gap-fitted and provided with a snap-fit ​​structure (not specifically shown in the figure); when the sealing ring is pushed in, the snap-fit ​​structure is engaged; when the sealing ring is installed, the spring is compressed and the snap-fit ​​structure is disengaged.

[0057] When the sealing ring is pushed, the snap-fit ​​mechanism engages, securing the relative position between the end portion 22 and the main body 21, thereby stably tensioning the sealing ring. When the sealing ring reaches the target installation position, for example, when the sealing ring fixture 20 is pushed until it contacts the target product with a certain force, the spring compresses, disengaging the snap-fit ​​mechanism. This causes the first notch 20a and the second notch 20b to move toward each other along the axial direction Z, loosening the sealing ring and allowing it to spring back into the target product. The spring then returns the end portion 22 and the main body 21 to their initial position, and the snap-fit ​​mechanism reengages.

[0058] In some embodiments, the buckle structure includes an arc-shaped protrusion and an arc-shaped groove respectively formed on the connecting portion 222 and the main body 21. The arc-shaped protrusion cooperates with the arc-shaped groove to facilitate the disengagement of the buckle structure when the sealing ring is installed, so that the sealing ring is loosened.

[0059] In some embodiments, the guide tube 10 is a steel tube. Steel tubes have strong structural strength, low cost, and can provide a good guide for the installation of the sealing ring. The material of the steel tube is, for example, 302 stainless steel, but is not limited thereto.

[0060] In some embodiments, the drive mechanism 30 is a pneumatic cylinder. The pneumatic cylinder provides a precise and efficient push. The pneumatic cylinder can be a long-distance cylinder so that the push rod can extend into the guide tube 10 and push the sealing ring fixture 20 into place.

[0061] In some embodiments, the guide tube 10 and the driving mechanism 30 are both mounted on the mounting bracket 40. In this way, the guide tube 10 and the driving mechanism 30 are stably mounted.

[0062] In summary, the sealing ring installation device of the present invention effectively reduces friction between the sealing ring and the guide tube 10 by forming honing grooves on the inner wall of the guide tube 10, providing a reliable guide for the installation of the sealing ring and improving the qualified installation rate of the sealing ring. The regular patterns formed by the honing grooves ensure that the sealing ring is evenly stressed during its movement within the guide tube 10, avoiding local deformation. The regular patterns formed by the honing grooves also provide an oil storage function, allowing lubricating oil to fill the gaps between the honing grooves, thereby increasing the lubrication effect, reducing lubricating oil usage, and avoiding equipment contamination. In addition, the present invention tensions the sealing ring and accurately pushes the sealing ring to the target installation position through the drive mechanism 30 and the sealing ring fixture 20. The sealing ring fixture 20 then releases the sealing ring, allowing the sealing ring to spring into the target product by its own elastic force.

[0063] The sealing ring installation device of the utility model can improve the qualified rate of sealing ring installation from the original 72% to above 99.92% after testing.

[0064] The sealing ring installation device of the present invention is particularly suitable for the installation of dynamic sealing rings with sealing lips, such as the installation of sealing rings of connecting rods of integrated brake control systems. It can utilize the honing grooves formed on the inner wall of the guide tube 10 to provide a stable guide for the installation of the sealing ring, thereby avoiding deformation of the sealing lip, and utilize the sealing ring clamp 20 and the driving mechanism 30 to achieve accurate installation of the sealing ring.

[0065] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
