Description

Technical Field

[0001] The present invention relates to the technical field of brake assembly, and in particular to a brake installation method and system. Background Art

[0002] During the brake installation process, the sealing ring needs to be installed in the mounting groove of the brake cylinder. The operation method commonly used in the existing technology is to apply an external force to squeeze the sealing ring radially inward, causing it to deform and achieve a reduction in diameter. After completing this operation, the sealing ring is placed in the corresponding mounting groove. In this process, the inherent resilience of the sealing ring itself is considered a key characteristic. After the external squeezing effect is removed, this force theoretically drives the sealing ring material to try to restore its original shape and size. This expected rebound behavior is the basic mechanism for achieving the final stable embedding of the sealing ring in the mounting groove. Its function is to enable the sealing ring to fully expand after the diameter is reduced until its outer wall or specific sealing part forms the necessary close contact and interference fit with the groove wall of the mounting groove, thereby ensuring that the sealing ring is firmly fixed in the mounting groove and providing structural support for the subsequent sealing function.

[0003] However, the main problem faced by the existing technology is that the actual resilience provided by the sealing ring material has inherent limitations. When the sealing ring is forcibly squeezed and compressed during installation, it is limited by the elastic recovery ability of the material itself and cannot produce sufficient and timely radial rebound after the external pressure is removed. This insufficient rebound directly results in the sealing ring being unable to effectively return to the expected size or generate sufficient radial expansion force. As a result, the sealing ring cannot achieve the required stable engagement state in the installation groove. Specifically, it cannot form a reliable fit between the sealing ring and the installation groove wall, and there is a risk of loosening, falling off or sealing failure. Summary of the Invention

During this process, the movement of the installation unit within the sealing ring's interior along the second set direction effectively applies a radially outward expansion force to the sealing ring, thereby forcing its outer peripheral wall into a secure interference fit with the installation groove. This operation overcomes the limitation of the sealing ring's inherent material resilience, which can lead to insufficient rebound. Ultimately, it resolves the issue of the sealing ring's inability to securely install within the brake unit's mounting groove, ensuring reliable installation and securing the sealing ring within the groove.

[0019] During the brake installation process, the seal ring 42 needs to be installed into the installation groove 413 of the brake unit 41. This process often squeezes the seal ring 42, allowing it to be placed into the brake cylinder 412 of the brake unit 41. However, due to the limited resilience of the seal ring 42, the seal ring 42 does not rebound sufficiently and cannot effectively return to the required state for a secure installation.

[0020] The brake includes a brake assembly 40, a base assembly 10, a first mounting assembly 20, and a second mounting assembly 30. The brake assembly 40 includes a brake unit 41 and a sealing ring 42. The brake unit 41 includes a support arm 411, a brake cylinder 412, and a mounting groove 413. The brake cylinder 412 is configured as a cylindrical body with one end open. The support arm 411 is connected to the side of the brake cylinder 412 away from the opening. The mounting groove 413 is recessed from the inner circumferential wall of the brake cylinder 412 toward the outer circumferential wall of the brake cylinder 412. The outer diameter of the sealing ring 42 is greater than the inner diameter of the brake cylinder 412 and less than or equal to the inner diameter of the mounting groove 413. The first mounting assembly 20 includes a positioning portion 21. The positioning portion 21 is connected to the base assembly 10. The positioning portion 21 is used to fix the relative position of the base assembly 10 and the brake unit 41. The second mounting assembly 30 includes a retracting unit 31, a mounting unit 33, and a movable groove 32. The retracting unit 31 includes a first retracting module 312 and a support portion 313. The first shrinking module 312 is connected to the supporting portion 313. The first shrinking module 312 is located in an area where the supporting portion 313 is projected toward the first shrinking module 312.

[0021] Example 1: This example discloses a brake installation method, such as Figure 1 As shown, the installation method may include steps S10 to S40 performed in sequence, and each step is described in detail as follows: In step S10, based on the installation instruction trigger, the installation unit 33 presses the outer peripheral wall of the sealing ring 42 along the first setting direction through the moving groove 32 to the first setting state. The first setting direction includes the direction from the first end of the moving groove 32 in the length direction to the second end of the moving groove 32 in the length direction, that is, Figure 5 As shown from right to left, the first set state includes the maximum diameter of the outer circumference of the sealing ring 42 being smaller than the diameter of the brake cylinder 412 of the brake unit 41. By squeezing the sealing ring 42 to make its diameter smaller than the diameter of the brake cylinder 412, the sealing ring 42 can easily enter the space enclosed by the brake cylinder 412, creating conditions for subsequent movement.

[0022] In step S20, after the installation unit 33 compresses the sealing ring 42 along the first set direction through the movable groove 32 to a first set state, the retraction unit 31 drives the sealing ring 42 to move to a second set state. The second set state includes the sealing ring 42 being located within the space enclosed by the brake cylinder 412, with the radial projection of the sealing ring 42 coinciding with the installation groove 413 of the brake unit 41. By positioning the sealing ring 42 within the space enclosed by the brake cylinder 412 and aligning its radial projection with the installation groove 413 of the brake unit 41, the sealing ring 42 is initially aligned with the installation position, paving the way for subsequent engagement of the installation unit 33.

[0023] In step S30, based on the retraction unit 31 driving the sealing ring 42 to move to the second set state, the installation unit 33 moves through the movement groove 32 into the space enclosed by the inner circumferential wall of the sealing ring 42. By entering the space enclosed by the inner circumferential wall of the sealing ring 42, the installation unit 33 is in a position to apply a force to the sealing ring 42, preparing to directly drive the sealing ring 42.

[0024] In step S40, based on the installation unit 33 moving through the movable groove 32 to the space surrounded by the inner wall of the sealing ring 42, the installation unit 33 drives the sealing ring 42 to move to the third setting state along the second setting direction. The second setting direction includes the direction from the second end of the movable groove 32 to the first end of the movable groove 32 in the longitudinal direction, that is, Figure 5 As shown from left to right. The third setting state includes the outer peripheral wall of the sealing ring 42 abutting against the installation groove 413. The sealing ring 42 is driven to partially abut against the installation groove 413 by the contraction unit 31 to achieve preliminary fixation of the sealing ring 42. Then, while the sealing ring 42 itself provides a rebound force, the sealing ring 42 is driven to move along the second setting direction by the installation unit 33 until the outer peripheral wall of the sealing ring 42 abuts against the installation groove 413, so that the sealing ring 42 rebounds fully, thereby solving the problem that the sealing ring 42 cannot be firmly installed in the installation groove 413. Furthermore, the movement speed of the installation unit 33 when driving the sealing ring 42 to move to the third setting state along the second setting direction can be fast at first and then slow, so that the installation unit 33 can be consistent with the rebound speed of the sealing ring 42.

[0025] Furthermore, step S10 includes step S11 and step S12. Step S11, step S12, step S20, step S30, and step S40 are performed in sequence. Step S11 and step S12 are described in detail as follows: In step S11, triggered by the installation instruction, the installation unit 33 drives the sealing ring 42 to move to a fourth set state. The fourth set state includes the spacing between the central axis of the first retractable module 312 and the central axis of the installation groove 413 being less than a first set spacing, which can be 0 mm to 5 mm. This allows the central axis of the first retractable module 312 and the central axis of the installation groove 413 to coincide with or nearly coincide with each other, and the sealing ring 42 is spaced apart on the side of the installation groove 413 away from the support arm 411. By pre-moving the sealing ring 42 close to the bottom of the brake cylinder 412, premature compression of the sealing ring 42 is avoided, thereby reducing the impact of prolonged compression on the resilience of the sealing ring 42.

[0026] In step S12, the installation unit 33 drives the sealing ring 42 to move to the fourth set state. The installation unit 33 compresses the outer peripheral wall of the sealing ring 42 along the first set direction to the first set state through the movable groove 32. By compressing the sealing ring 42 as it moves below the brake cylinder 412, the sealing ring 42 is compressed only when it is about to enter the brake cylinder 412, thereby preventing damage to the sealing ring 42 due to prolonged compression.

[0027] Furthermore, step S40 includes step S41 and step S42, and step S10, step S20, step S30, step S41, and step S42 are performed in sequence. Step S41 and step S42 are described in detail as follows: In step S41, after the installation unit 33 has moved through the movable groove 32 into the space enclosed by the inner circumferential wall of the sealing ring 42, the installation unit 33 drives the inner circumferential wall of the sealing ring 42 in the movable groove 32 along a first set direction. By driving the inner circumferential wall of the sealing ring 42, the position of the sealing ring 42 is adjusted so that the portion of the sealing ring 42 near the second end of the movable groove 32 in the longitudinal direction can enter the installation groove 413, thereby achieving preliminary positioning of the sealing ring 42.

[0028] In step S42, based on the installation unit 33 moving along the first set direction in the movable groove 32 until the distance between the installation unit 33 and the inner wall of the brake cylinder 412 is less than the second set distance, the installation unit 33 drives the sealing ring 42 to move to the third set state along the second set direction. The second set distance can be 30% of the difference between the outer diameter of the sealing ring 42 and the inner diameter of the sealing ring 42. After the sealing ring 42 enters the installation groove 413, in order to achieve sealing, a part of the sealing ring 42 will be located in the space surrounded by the brake cylinder 412 and cannot enter the installation groove 413. The sealing ring 42 is a flexible material and can be compressed. If the sealing ring 42 does not enter the installation groove 413, even if the sealing ring 42 is squeezed, the distance between the mounting portion 331 and the inner wall of the brake cylinder 412 will be relatively large and will not be less than the second set distance. Therefore, when it is detected that the installation unit 33 moves along the first set direction in the movable groove 32 until the distance between the installation unit 33 and the inner wall of the brake cylinder 412 is less than the second set distance, it can be determined that this part of the sealing ring 42 has entered the installation groove 413, and then subsequent steps are performed to improve the success rate of the installation of the sealing ring 42.

[0029] Furthermore, step S30 includes steps S31 to S33, and steps S10, S20, S31, S32, and S40 are performed in sequence. Steps S31 to S33 are described in detail as follows: In step S31, based on the retraction unit 31 driving the sealing ring 42 to move to the second setting state, the installation unit 33 moves along the support arm 411 to the installation groove 413 (i.e., downward direction) to be spaced apart from the sealing ring 42 to prevent the sealing ring 42 from being damaged during the subsequent movement of the installation unit 33. Figure 6 The lower end surface causes friction, which improves installation efficiency by reducing the movement path of the installation unit 33.

[0030] In step S32, based on the installation unit 33 moving along the direction from the support arm 411 to the installation groove 413 to be spaced apart from the sealing ring 42, the installation unit 33 moves to the projection area of ​​the space surrounded by the inner peripheral wall of the sealing ring 42 toward the installation unit 33 (i.e., Figure 4 top-down orientation as shown).

[0031] In step S33, based on the installation unit 33 moving to the projection area of ​​the space surrounded by the inner wall of the sealing ring 42 toward the installation unit 33, the installation unit 33 moves into the space surrounded by the inner wall of the sealing ring 42. By directly entering the space surrounded by the inner wall, additional movement is avoided, thereby improving the installation efficiency.

[0032] Preferably, step S30 includes steps S34 to S37, and steps S10, S20, S34, S35, S36, S37, and S40 are performed in sequence. Steps S34 to S37 are described in detail as follows: In step S34, based on the retraction unit 31 driving the sealing ring 42 to move to the second set state, the installation unit 33 moves a set distance in the second set direction. This prevents relative friction between the installation portion 331 and the outer periphery of the sealing ring 42, thereby reducing wear and vibration of the sealing ring 42. Vibration can cause the sealing ring 42 to deviate from the installation groove 413, affecting the installation position accuracy of the sealing ring 42. Furthermore, the installation unit 33 moves a set distance in the second set direction at a set speed, which can be greater than the rebound speed of the sealing ring 42.

[0033] In step S35, based on the installation unit 33 moving the set distance in the second set direction, the installation unit 33 moves in the third set direction to a sixth set state. The third set direction includes the direction from the support arm 411 to the installation groove 413 (i.e., from top to bottom). The sixth set state includes the sealing ring 42 spaced apart from the installation unit 33 in the third set direction. This further reduces friction between the installation unit 33 and the sealing ring 42.

[0034] In step S36, based on the installation unit 33 moving to the sixth setting state along the third setting direction, the installation unit 33 moves to the projection area of ​​the space surrounded by the inner peripheral wall of the sealing ring 42 toward the installation unit 33, that is, Figure 4 By moving the sealing ring 42 into the projection area of ​​the space enclosed by the inner peripheral wall of the sealing ring 42 toward the mounting unit 33 , the mounting unit 33 can accurately position the sealing ring 42 .

[0035] In step S37, the installation unit 33 moves into the projection area of ​​the space enclosed by the inner circumferential wall of the sealing ring 42 toward the installation unit 33. The installation unit 33 moves into the space enclosed by the inner circumferential wall of the sealing ring 42. By moving the installation unit 33 into the space enclosed by the inner circumferential wall, the installation unit 33 can position the sealing ring 42 while avoiding friction and vibration of the sealing ring 42, ensuring stable installation.

[0036] Preferably, the set distance is 30% to 80% of the distance between the first set position and the second set position. The first set position includes the position of the mounting unit 33 proximal to the sealing ring 42 when the sealing ring 42 is in the first set state. The second set position includes the position of the mounting unit 33 proximal to the sealing ring 42 when the mounting unit 33 abuts the inner circumferential wall of the brake cylinder 412. If the movement distance is too large, the moving unit may impact the brake cylinder 412, which will also increase the moving time and reduce efficiency. If the movement distance is too small, the rebound force of the sealing ring 42 itself is large (the more compressed the sealing ring 42, the greater the rebound force), resulting in greater friction between the moving unit and the sealing ring 42, causing damage to the sealing ring 42. By setting the distance to 30% to 80% of the distance between the first set position and the second set position, excessive movement can be avoided, preventing collisions caused by excessive movement and friction caused by insufficient movement, thereby balancing brake installation efficiency and preventing damage to the sealing ring 42.

[0037] Furthermore, step S10 includes steps S13 to S15, and steps S13, S14, S15, S20, S30, and S40 are performed in sequence. Steps S13 to S15 are described in detail as follows: In step S13, based on the detection of the brake unit 41 by the sensor 23, the pressing portion 22 moves to abut against the positioning portion 21 and sleeves the sealing ring 42 on the outer peripheral side of the first contraction module 312. The movement of the pressing portion 22 and the sleeve of the sealing ring 42 are triggered by the sensor 23 to achieve the conditions for triggering the installation instruction, ensuring that the device responds accurately. The first installation component 20 includes a sensor 23, which is connected to the base 11 and is arranged on one side of the positioning portion 21. When the sensor 23 detects that there is a brake unit 41 on the first positioning unit, it is determined that the installation unit 33 can move the sealing ring 42 to below the brake cylinder 412 detected by the sensor 23.

[0038] In step S14 , the installation instruction is triggered based on the pressing portion 22 moving to abut against the positioning portion 21 and the sealing ring 42 being sleeved on the outer circumference of the first shrinking module 312 .

[0039] In step S15, triggered by the installation instruction, the installation unit 33 presses the outer peripheral wall of the sealing ring 42 along the first set direction to the first set state through the movable groove 32. The relative position of the brake unit 41 and the positioning portion 21 is fixed by the pressing portion 22, thereby reducing unnecessary displacement of the brake unit 41 during assembly.

[0040] Embodiment 2: This embodiment discloses a brake installation system, which can be applied to the brake installation method of any of the above embodiments. The brake installation system includes a brake assembly 40, a base assembly 10, a first installation assembly 20, and a second installation assembly 30.

The mounting groove 413 is recessed from the inner circumferential wall of the brake cylinder 412 toward the outer circumferential wall of the brake cylinder 412. The outer diameter of the sealing ring 42 is larger than the inner diameter of the brake cylinder 412 and smaller than or equal to the inner diameter of the mounting groove 413. The first mounting assembly 20 includes a positioning portion 21. The positioning portion 21 is connected to the base assembly 10. The positioning portion 21 is used to fix the relative position of the base assembly 10 and the brake unit 41. The second mounting assembly 30 includes a retracting unit 31, a mounting unit 33, and a movable groove 32. The retracting unit 31 includes a first retracting module 312 and a support portion 313. The support portion 313 is movably connected to the base assembly 10. The first retracting module 312 is connected to the support portion 313. The first shrinking module 312 is located in the area where the support portion 313 is projected toward the first shrinking module 312. The sealing ring 42 can be sleeved on the outer peripheral side of the first shrinking module 312, and one axial end of the sealing ring 42 can abut against the end of the support portion 313 close to the first shrinking module 312, so that the support portion 313 supports the sealing ring 42, so that the sealing ring 42 can move synchronously with the support portion 313. Figure 3 As shown, the base assembly 10 includes a base 11 and a rotating disk 12, and the rotating disk 12 is movably connected to the base 11. A plurality of positioning parts 21 are connected to the rotating disk 12, and the plurality of positioning parts 21 are spaced apart along the circumferential direction of the rotating disk 12. The support arm 411 is detachably connected to the positioning part 21, and the positioning part 21 is used to fix the relative position of the base 11 and the brake unit 41. The shrinkage unit 31 also includes a first driving part 314, and the first driving part 314 is provided on the base 11 and the first driving part 314 is drivingly connected to the support part 313. The support part 313 is movably connected to the base 11 through the first driving part 314. The first driving part 314 can drive the support part 313 to move toward or away from the brake cylinder 412. As shown Figure 2As shown, the second mounting assembly 30 also includes a feeding unit 34, which includes a feeding portion 341 and a grabbing portion 342.

The grabbing portion 342 is connected to the base 11, and the grabbing portion 342 can grab the sealing ring 42 on the feeding portion 341 and sleeve it on the outer peripheral side of the first shrinking module 312.

[0041] The diameter of the support portion 313 is larger than the inner diameter of the sealing ring 42 and smaller than or equal to the inner diameter of the brake cylinder 412, so that the support portion 313 can drive the sealing ring 42 into the brake cylinder 412. The first retracting module 312 is smaller than or equal to the inner diameter of the brake cylinder 412 and smaller than the inner diameter of the sealing ring 42. The movable groove 32 passes through the first retracting module 312 and the support portion 313 from one side to the other side along the radial direction of the first retracting module 312. Figure 6 As shown, the mounting unit 33 is movably connected to the support portion 313. The mounting unit 33 can change the shape of the sealing ring 42 on the support portion 313 through the movable groove 32, so that the sealing ring 42 can be placed in the mounting groove 413 of the brake cylinder 412. The width of the movable groove 32 is greater than or equal to the sum of twice the difference between the outer diameter of the sealing ring 42 and the inner diameter of the sealing ring 42 and the width of the mounting unit 33, so that the mounting unit 33 can drive the sealing ring 42 to move in the movable groove 32. Further, as Figure 7 As shown, the mounting unit 33 includes a mounting portion 331, a second driving portion, and a third driving portion. The second driving portion is connected to the support portion 313. The third driving portion is also connected to the support portion 313. The mounting portion 331 is movably connected to the support portion 313 via the second and third driving portions. The mounting portion 331 can change the shape of the sealing ring 42 on the support portion 313 via the movable groove 32, thereby allowing the sealing ring 42 to be placed within the mounting groove 413 of the brake cylinder 412. The width of the movable groove 32 is greater than or equal to the sum of twice the difference between the outer diameter and the inner diameter of the sealing ring 42 and the width of the mounting portion 331, allowing the mounting portion 331 to drive the sealing ring 42 within the movable groove 32. The mounting portion 331 is drivingly connected to the second driving portion. The mounting portion 331 is drivingly connected to the third driving portion. The second driving portion drives the mounting portion 331 to move horizontally, while the third driving portion drives the mounting portion 331 to move vertically.

[0042] Further, if Figure 9As shown, the first contraction module 312 includes two first contraction platforms 3121 and two second contraction platforms 3122. The first contraction platform 3121 and the second contraction platform 3122 are respectively connected to the same side of the support portion 313. The first contraction platform 3121 is arranged on one side of the width direction of the movable groove 32. The second contraction platform 3122 is arranged on the other side of the width direction of the movable groove 32. The distance between the two first contraction platforms 3121 gradually decreases along the first set direction. The outer peripheral side of the first contraction platform 3121 is smoothly transitioned. The outer peripheral side of the second contraction platform 3122 is smoothly transitioned. As shown Figure 10 As shown, the first and second contraction platforms 3121, 3122 can be arranged in a semicircular shape, with the arc portion of the first contraction platform 3121 positioned away from the second contraction platform 3122. The arc portion of the second contraction platform 3122 is positioned away from the first contraction platform 3121. When squeezing the sealing ring 42, the smooth transition between the outer circumferences of the first and second contraction platforms 3121, 3122 prevents the sealing ring 42 from being damaged or even broken by excessive bending.

[0043] Furthermore, the shrinking unit 31 also includes a second shrinking module 311. The second shrinking module 311 includes a third shrinking platform 3111 and an avoidance opening 3112. The height of the first shrinking module 312 is greater than or equal to the axial dimension of the sealing ring 42. The second shrinking module 311 is connected to the end of the first shrinking module 312 away from the support portion 313. The maximum inner diameter of the sealing ring 42 when it is in the first setting state is smaller than the diameter of the second shrinking platform 3122. The diameter of the third shrinking platform 3111 is smaller than or equal to the inner diameter of the sealing ring 42. The avoidance opening 3112 is recessed from one radial side of the third shrinking platform 3111 toward the other side. By providing the avoidance opening 3112, the sealing ring 42 is prevented from being twisted and deformed after being squeezed, thereby ensuring the installation quality of the sealing ring 42.
