Description

Technical Field

[0001] This invention relates to the field of tooling installation technology, and more specifically, to a bushing installation method and system. Background Technology

[0002] During the assembly of the connecting beam assembly, bushings are typically pressed into the corresponding mounting holes of the upper and lower beams of the connecting beam in sequence to achieve the assembly connection between the bushings and the connecting beam assembly. In related technologies, a pressure head with a flat end face is usually used to press the bushings in one go. To control the axial distance between the upper and lower beams after assembly with the bushings and to avoid damage to the parts, the upper beam is set to an inclined state before pressing. After the bushing is placed into the connecting beam, it is also in an inclined state before pressing. When the pressure head directly acts on the inclined end face of the bushing, localized pre-contact is likely to occur in the contact area between the pressure head and the bushing end face. This results in uneven distribution of the pressing force on the bushing, which can easily cause local crushing, deformation, or misalignment of the pressing posture. Simultaneously, the central axis of the bushing is difficult to stably align with the central axis of the second mounting hole, affecting the assembly accuracy of the bushing between the two mounting holes.

[0003] Furthermore, during the pressing process of the bushing from the upper side beam to the lower side beam of the connecting beam, the gap between the upper and lower side beams changes with the pressing action. If a supporting structure is lacking to mate with the two side beams, problems such as excessively narrow gaps, collision interference, or deformation under stress may occur between the side beams. If the supporting structure is not easily removable from the side beams, it may also cause pulling damage to the connecting beam assembly after pressing. Therefore, there is an urgent need to provide a bushing installation method and system that can solve the problems of bushing damage, deformation, and misalignment during the pressing process.

[0034] To address the problems of bushing damage, deformation, and press-fit misalignment during assembly, this invention offers the following advantages:

[0035] This invention utilizes a pressing assembly to sequentially press the bushing through a first pressing zone and a second pressing zone in stages, thereby adapting to the bushing's tilted posture at a first preset position. The height of the first pressing zone gradually increases along the pressing direction towards the second pressing zone, allowing for a more thorough contact with the tilted bushing end face. This ensures a more uniform pressing force as the bushing's central axis gradually changes from tilted to vertical, reducing the risk of localized crushing, deformation, or damage to the bushing due to excessive localized stress. After the first stage of pressing, the pressing assembly moves a preset distance along the recovery direction and rotates a second preset angle, separating the first pressing zone from the bushing before adjusting the second pressing zone to a position suitable for continued pressing. The second pressing zone is a plane perpendicular to the pressing direction, allowing for planar pressing of the bushing end face after the tilt has decreased. This further homogenizes the stress on the bushing end face and improves the alignment stability when the bushing is pressed onto the second side beam. Therefore, this invention prevents damage, deformation, and misalignment of the bushing during the pressing process. Attached Figure Description

[0047] In existing technologies, bushings are typically press-fitted in one go using a pressure head with a flat end face. To control the axial distance between the upper and lower beams of the connecting beam after they are fitted with the bushing, and to avoid damage to parts or difficulty in assembling with other parts due to excessively narrow gaps, the upper beam is set in an inclined position before pressing. After the bushing is placed into the connecting beam, it is also in an inclined state before pressing. When the pressure head acts directly on the end face of the bushing in an inclined state, the pressing force on the bushing is unevenly distributed, which can easily cause local crushing, deformation, or offset of the pressing posture. Therefore, a bushing installation method is needed to solve the problems of bushing damage, deformation, and offset during pressing.

[0048] Example 1:

[0049] This invention discloses a bushing installation method; please refer to [the relevant documentation]. Figure 1This includes steps S10-S30:

[0050] Step S10: Based on the bushing 50 being pre-installed at a first preset position on the connecting beam assembly 40, the pressing assembly 30 is driven to press the bushing 50 to a second preset position on the connecting beam assembly 40 along the pressing direction using the first pressing area 321; wherein, at the first preset position, the central axis of the bushing 50 and the central axis of the connecting beam assembly 40 at a third preset position have a first preset angle α along the pressing direction; wherein, the first preset angle α is, for example, 0°-15°, including but not limited to, and the specific value shall be subject to the actual value.

[0051] Specifically, in the first stage of pressing, the bushing 50 is pre-installed at the first preset position of the connecting beam assembly 40, so that the bushing 50 is in an inclined posture. The pressing assembly 30 presses the bushing 50 along the pressing direction with the first pressing area 321. This avoids the problem that when the bushing 50 is in an inclined state, the pressing assembly 30 and the surface of the bushing 50 do not fit together, causing the pressure to concentrate at the pressure point on the surface of the bushing 50, thereby damaging the surface of the bushing 50 or even causing pressing misalignment.

[0052] Step S20: Based on the bushing 50 being located at the second preset position, drive the pressing assembly 30 to move a preset distance along the recovery direction and drive the pressing assembly 30 to rotate a second preset angle; wherein, the pressing direction is opposite to the recovery direction; the second preset angle can be 90°, depending on the actual application.

[0053] Specifically, after the first stage of pressing is completed, the pressing component 30 is moved along the recovery direction and then driven to rotate by a second preset angle, so that the pressing component 30 rotates in the direction of pressing without damaging the surface of the bushing 50, in preparation for the second stage of pressing mentioned below.

[0054] Step S30: Based on the pressing component 30 moving a preset distance and rotating a second preset angle, drive the pressing component 30 to press the bushing 50 to a third preset position along the pressing direction with the second pressing area 322; wherein, the first pressing area 321 and the second pressing area 322 are on the side of the pressing component 30 facing the connecting beam component 40; the height of the first pressing area 321 along the pressing direction gradually increases towards the second pressing area 322; the second pressing area 322 is a plane perpendicular to the pressing direction.

[0055] In this design, the flat pressure head of the pressing assembly 30 is changed to a central flat surface and two inclined surfaces with tilted angles on both sides. This divides the pressing assembly 30 into two pressing areas: a first pressing area 321 and a second pressing area 322. Simultaneously, the pressing process is divided into two stages. In the first stage, the first pressing area 321 is used to press the bushing 50 pre-installed on the connecting beam. Because the first side beam 412 of the connecting beam is in an inclined position before pressing, the bushing 50 pre-installed on it is also in an inclined state. The first pressing... Zone 321 is an inclined surface of the pressing component 30 with an angle. During pressing, the inclined surface of the first pressing zone 321 is in contact with the surface of the highest point of the inclination of the bushing 50, and the lowest point of the inclination of the bushing 50 is separated from the pressing component 30. This makes the contact area between the first pressing zone 321 of the pressing component 30 and the surface of the bushing 50 greater than the contact area between the flat head and the highest point of the inclination of the bushing 50. This avoids the bushing 50 from being crushed, deformed, or having its pressing posture shifted during the pressing process due to the small local contact area between the pressing component 30 and the surface of the bushing 50.

[0056] The bushing 50 is pressed into the second preset position, and the inclined bushing 50 is pressed until its surface is close to being horizontal with the reference plane. That is, during the first pressing stage, the first preset included angle α of the bushing 50 gradually decreases, and the height difference between the highest and lowest points of the inclined bushing 50 also gradually decreases. Based on the rotation of the pressing assembly 30 by the second preset included angle, the pressing process enters the second pressing stage. In this stage, the second pressing area 322 is a plane perpendicular to the pressing direction. The second pressing area 322 contacts the end face of the bushing 50, so that the planar second pressing area 322 can simultaneously abut against the end face of the bushing 50 after the height difference decreases in the first pressing stage, further eliminating the end face height difference. The contact area between the second pressing area 322 and the end face of the bushing 50 gradually increases, reducing the probability of deformation or crushing of the bushing 50 by the pressing assembly 30.

[0057] Specifically, steps S01, S02, and S03 are executed sequentially before step S10, as detailed below. Furthermore, the bushing installation method also includes step S01:

[0058] Step S01: Based on the connection beam assembly 40 being installed on the support assembly 20, the central axis of the first side beam 412 has a first preset angle α with the pressing direction, and the central axis of the second side beam 413 coincides with the pressing direction; wherein, the connection beam assembly 40 includes a connection beam body 411 and a first side beam 412 and a second side beam 413 disposed at at least one end of the connection beam body 411; the first side beam 412 and the second side beam 413 are spaced apart along the pressing direction.

[0059] Specifically, in related technologies, the upper and lower side beams of the connecting beam are usually spaced apart. This gap is used for assembly with other mechanical structures. If the gap is too narrow, it will not be able to be assembled with other mechanical structures. To avoid this problem, in this solution, the first side beam 412 is set to be inclined upward relative to the reference plane. This avoids the collision interference caused by the first side beam 412 being too narrow after being subjected to pressure by the pressing assembly 30 along the pressing direction. This ensures that the gap between the first side beam 412 and the second side beam 413 after pressing the connecting beam assembly 40 is in a qualified state under the same pressure, thereby facilitating the assembly of the connecting beam assembly 40 with other mechanical structures.

[0060] Furthermore, the bushing installation method also includes steps S02-S03:

[0061] Step S02: Based on the connection beam assembly 40 being installed on the support assembly 20, the third support seat 213 of the support assembly 20 is installed at the gap between the first side beam 412 and the second side beam 413 along the pressing direction, and the first side beam 412 and the second side beam 413 abut against the opposite sides of the third support seat 213 along the pressing direction; wherein, the support assembly 20 includes the second support seat 212 and the third support seat 213; the connection beam assembly 40 is installed on the second support seat 212; the third support seat 213 and the second support seat 212 are arranged radially spaced apart;

[0062] Specifically, by installing the third support 213 at the gap between the first side beam 412 and the second side beam 413 along the pressing direction, when the first side beam 412 is subjected to pressure from the pressing assembly 30 along the pressing direction, the third support 213 simultaneously applies a force to the first side beam 412 opposite to the pressing direction, thereby controlling the gap between the first side beam 412 and the second side beam 413 to be too narrow under the pressure of the pressing assembly 30, and thus providing support for the first side beam 412.

[0063] Step S03: Based on the third support 213 being installed at the gap between the first side beam 412 and the second side beam 413 along the pressing direction, the bushing 50 is pre-installed in the first mounting hole 421 of the first side beam 412; wherein, the first preset position includes the bushing 50 being pre-installed in the first mounting hole 421; in the first preset position, the central axis of the bushing 50 and the central axis of the second side beam 413 have a first preset angle α along the pressing direction.

[0064] Specifically, by axially spacing the first side beam 412 and the second side beam 413, the third support 213 is installed at the gap between the first side beam 412 and the second side beam 413 to provide support for the first side beam 412 and the second side beam 413. This prevents the gap between the first side beam 412 and the second side beam 413 from becoming too narrow after the pressing assembly 30 applies force to the first side beam 412. At the same time, in order to control the axial spacing between the first side beam 412 and the second side beam 413, in addition to installing the third support 213, the first side beam 412 is also set to an inclined state before pressing, and the bushing 50 is pre-installed in the first mounting hole 421 of the first side beam 412 so that the bushing 50 also has an inclined state before pressing. In this solution, the first pressing area 321 of the pressing assembly 30 is used to press the bushing 50. The first pressing area 321 has an inclined surface that can fit with the bushing 50 in the inclined state, avoiding local crushing of the bushing 50 due to excessive local force.

[0065] Specifically, steps S11, S12, S13, S14, S20, and S30 are executed sequentially, as detailed below.

[0066] Further, in step S10, based on the bushing 50 being pre-installed at a first preset position on the connecting beam assembly 40, driving the pressing assembly 30 to press the bushing 50 to a second preset position on the connecting beam assembly 40 along the pressing direction in the first pressing area 321 includes steps S11-S14:

[0067] In step S11, based on the bushing 50 being pre-installed at a first preset position on the connecting beam assembly 40, the radial end face of the bushing 50 has a third preset angle β with the reference plane; wherein, the reference plane is a plane perpendicular to the pressing direction; the third preset angle β can be 0°-15°, depending on the actual application. The bushing 50 is installed in an inclined state.

[0068] In step S12, based on the third preset angle β between the radial end face of the bushing 50 and the reference plane, the first pressing area 321 of the pressing assembly 30 is moved along the pressing direction and abuts against the end face of the bushing 50. The height of the first pressing area 321 of the pressing assembly 30 increases towards the second pressing area 322 along the pressing direction, that is, the first pressing area 321 is an inclined slope, which is used to abut against the bushing 50 with an inclined posture. This increases the contact area between the first pressing area 321 of the pressing assembly 30 and the highest point plane of the bushing 50 in the inclined posture, relative to the planar pressure head in the prior art. This avoids the problem of local crushing, deformation and pressing misalignment of the bushing 50 surface caused by the small contact area between the pressing assembly 30 and the inclined surface of the bushing 50, which would damage the surface of the bushing 50.

[0069] Step S13: Based on the first pressing area 321 of the pressing component 30, the bushing 50 is pressed along the pressing direction, and the third preset included angle β is gradually reduced to the target angle; wherein, the target angle refers to the angle position where the end face of the bushing 50 along the radial direction is flush with or below the reference surface.

[0070] In step S14, based on gradually decreasing to the target angle, the bushing 50 is pressed into the second preset position of the connecting beam assembly 40. When the bushing 50 is pressed into the second preset position, it means that in the first pressing stage, the pressing assembly 30 has changed the bushing 50 from its tilted state during pre-installation to a state where the surface of the bushing 50 is perpendicular to the reference plane, thus completing the pressing of the bushing 50 into the first mounting hole 421 of the connecting beam assembly 40.

[0071] Furthermore, after step S14, steps S21, S22, and S30 are executed sequentially, as detailed below.

[0072] Further, in step S20, based on the bushing 50 being located at the second preset position, driving the pressing assembly 30 to move a preset distance along the recovery direction and driving the pressing assembly 30 to rotate a second preset included angle includes steps S21-S22:

[0073] Step S21: Based on the pressing component 30 moving a preset distance along the recovery direction, the first pressing area 321 separates from the bushing 50;

[0074] Step S22: Based on the separation of the first pressing area 321 from the bushing 50, drive the pressing assembly 30 to rotate at a second preset angle.

[0075] Specifically, before the second stage of pressing, the first driving unit 12 first drives the pressing component 30 to move a preset distance along the recovery direction, so that the first pressing area 321 is separated from the bushing 50, which facilitates the subsequent rotation of the pressing component 30. By driving the pressing component 30 to rotate a second preset angle, the pressing component 30 is rotated to the second pressing area 322 for the subsequent second stage of pressing.

[0076] Further, steps S31 and S32 are executed sequentially, as detailed below.

[0077] Furthermore, in step S30, based on the pressing component 30 moving a preset distance and rotating a second preset angle, driving the pressing component 30 to press the bushing 50 to the third preset position along the pressing direction with the second pressing area 322, the process further includes step S31:

[0078] Step S31: Based on the separation of the first pressing zone 321 from the bushing 50, the third support seat 213 is driven to move towards the direction close to the central axis of the bushing 50; wherein, the third support seat 213 includes a second support body 2131, a third support body 2132, and a support groove 2133; the second support body 2131 is connected to the second support seat 212; the third support body 2132 is connected to the second support body 2131; the support groove 2133 is provided on the third support body 2132; at least part of the first side beam 412 and the second side beam 413 are located in the support groove 2133; the height of the third support body 2132 along the pressing direction gradually decreases towards the direction close to the connecting beam body 411.

[0079] Specifically, by driving the third support 213 to move closer to the central axis of the bushing 50, the first side beam 412 of the connecting beam is controlled to move closer to the second side beam 413 due to the pressure applied by the pressing assembly 30, thus avoiding the problem of excessively narrow spacing between the two side beams. In the prior art, a rectangular support structure is usually used to control the spacing between the upper and lower side beams of the connecting beam. The surface of the rectangular support structure is interference-fitted with the surface of the upper side beam, and the upper side beam fits more tightly with the rectangular support structure under uniform pressure. When the bushing 50 is pressed and the connecting beam is removed from the rectangular support structure, the friction between the rectangular support structure and the upper side beam is too large, which hinders the movement of the rectangular support structure away from the connecting beam, thereby damaging the surface of the upper side beam of the connecting beam. In this solution, the height of the third support body 2132 along the pressing direction decreases towards the connecting beam body 411, that is, the third support body 2132 is set into an inclined shape, so that the height decreases as it moves closer to the first side beam 413. In the direction of 12, at least part of the third support body 2132 has a gap with the surface of the first side beam 412, reducing the contact area and facilitating the removal of the connecting beam assembly 40 from the third support seat 213 after the bushing 50 is pressed, without damaging the surface of the first side beam 412. The support groove 2133 is located in the groove on the third support body 2132 near the connecting beam assembly 40, and is used to accommodate the axial gap between the first side beam 412 and the second side beam 413. The inclined structure of this application ensures the spacing between the first side beam 412 and the second side beam 413 during the pressing process, and also prevents damage to the connecting beam assembly 40 when the third support seat 213 is driven away from the connecting beam assembly 40.

[0080] Furthermore, in step S30, based on the pressing component 30 moving a preset distance and rotating a second preset angle, driving the pressing component 30 to press the bushing 50 to the third preset position along the pressing direction with the second pressing area 322, the process further includes step S32:

[0081] Step S32: Based on the movement of the third support 213 toward the direction of the central axis of the bushing 50, the second pressing area 322 of the pressing assembly 30 is driven to continue pressing the bushing 50 along the pressing direction and pressing the bushing 50 to the third preset position; wherein, the third preset position includes the bushing 50 being pressed into the second mounting hole 422 of the second side beam 413; the second side beam 413 is provided with the second mounting hole 422.

[0082] For details, please refer to Figure 2 , Figure 5 and Figure 6 In the second stage of pressing, the pressing assembly 30 continues to press the bushing 50 along the pressing direction using the second pressing zone 322. Since the bushing 50 has been gradually adjusted from an inclined posture to a surface that is radially horizontal with the reference plane in the first stage, the second pressing zone 322 contacts the end face of the bushing 50 in a planar manner, and the contact area with the surface of the bushing 50 gradually increases. This means the pressing force applied by the pressing assembly 30 to the surface of the bushing 50 tends to be uniform, causing the central axis of the bushing 50 to further approach the central axis of the second mounting hole 422, until the bushing 50 is pressed into the second mounting hole 422 of the second side beam 413, i.e., installed in the third preset position. The second pressing zone 322 can reduce localized off-center loads during the second stage of pressing, reducing the possibility of deformation, damage, or pressing misalignment of the bushing 50.

[0083] Further, steps S10, S20, S30, S40 and S50 are executed sequentially, as detailed below.

[0084] Furthermore, the bushing installation method also includes steps S40-S50:

[0085] In step S40, based on the bushing 50 being pressed to the third preset position, the pressing assembly 30 is driven to move along the recovery direction; after the bushing 50 is pressed, the pressing assembly 30 is driven to leave the surface of the bushing 50, which facilitates the subsequent removal of the bushing 50 and the connecting beam assembly 40.

[0086] In step S50, based on the movement of the pressing assembly 30 along the return direction, the third support 213 is driven to move away from the bushing 50. After the pressing assembly 30 is driven away from the surface of the bushing 50, the third support 213 is driven to move away from the bushing 50, so that the third support 213 is removed from the connecting beam assembly 40, making it easier to remove the bushing 50 and the connecting beam assembly 40.
