Description

Technical Field

[0001] This disclosure relates to the field of automotive assembly tool technology, and more specifically to a crash beam installation tool. Background Technology

[0002] The crash beam is a crucial safety component of a vehicle, a key part affecting collision safety. When installing crash beams using semi-automatic tools, a simple transport bracket is typically used. Its clamping part uses flat clamps to hold the upper and lower surfaces of the crash beam along its height, restricting its movement in that direction. However, during installation, the crash beam not only moves vertically but also longitudinally. This type of transport bracket cannot effectively restrict the longitudinal movement of the crash beam, resulting in unstable clamping and consequently affecting the quality of subsequent installation.

[0005] In some possible implementations, the first clamping part includes a first clamping body, and the limiting structure includes a first limiting part connected to the front end of the first clamping body. The first clamping body and the first limiting part are arranged in an L-shape, and the first limiting part is used to stop in front of the anti-collision beam; and / or, the second clamping part includes a second clamping body, and the limiting structure includes a second limiting part and a third limiting part. The second limiting part and the third limiting part are spaced apart on the second clamping body along the front-rear direction. The second limiting part is located in front of the third limiting part, and the second limiting part and the third limiting part are used to stop in front of the front and rear sides of the anti-collision beam.

[0006] In some possible implementations, the first limiting part, the second limiting part, and the third limiting part cooperate to form at least five constraint surfaces that restrict the movement of the anti-collision beam: the at least five constraint surfaces include a first constraint surface (S1) located on the first clamping body, a second constraint surface (S2) located on the first limiting part, a third constraint surface (S3) located on the second limiting part, a fourth constraint surface (S4) located on the second clamping body, and a fifth constraint surface (S5) located on the third limiting part.

[0007] In some possible implementations, the clamping mechanism further includes a first handle, a first connecting rod, a second connecting rod, a first support frame, a support beam, and a second column; the first support frame and the support beam are spaced apart from each other along the height direction and connected to the second column; the second clamping part is connected to the support beam; the first handle is hinged to the first support frame and can rotate about axis A; one end of the first connecting rod is hinged to the first handle and can rotate about axis B, and the other end is hinged to the second connecting rod and can rotate about axis C; one end of the second connecting rod is hinged to the first support frame and can rotate about axis D, and the other end is fixed to the first clamping part; the first handle is used to drive the second connecting rod and the first clamping part to rotate through the first connecting rod; wherein, axis D is the first pivot axis, and axis A, axis B, axis C, and axis D are parallel.

[0008] In some possible implementations, the walking mechanism includes a support frame, and the lifting mechanism includes a first column, a second support frame, a second handle, a fixed hinge, a third link, a fourth link, and a fifth link; the first column is mounted on the support frame, and the second support frame is mounted on the first column; the second handle is hinged to the second support frame and can rotate about the E-axis; one end of the fixed hinge is fixed to the second column, and the other end is hinged to the fifth link; one end of the third link is hinged to the second handle and can rotate about the F-axis, and the other end is hinged to the fourth link and can rotate about the G-axis; one end of the fourth link is hinged to the second support frame and can rotate about the H-axis, and the other end is hinged to the fifth link and can rotate about the I-axis; the second handle is used to drive the fixed hinge and the second column to move along the height direction via the third link, the fourth link, and the fifth link, wherein the E-axis, the F-axis, the G-axis, the H-axis, and the I-axis are parallel.

[0009] In some possible implementations, the fifth link has multiple hinge holes arranged in an array, and the fixed hinge seat and the fourth link can be hinged to any two different hinge holes respectively.

[0010] In some possible implementations, the lifting mechanism further includes a guide structure for guiding the movement of the clamping mechanism along the height direction.

[0014] Through the above technical solution, at least one of the first clamping part and the second clamping part is provided with a limiting structure for restricting the movement of the anti-collision beam in the front-back direction. The limiting structure provides active constraint in the front-back direction to prevent the anti-collision beam from slipping due to inertia when it suddenly stops or turns. Therefore, when the anti-collision beam is clamped, it is constrained both in the height direction and in the front-back direction, avoiding swaying and displacement of the anti-collision beam during handling or positioning, and improving the stability of clamping.

Detailed Implementation

[0018] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0019] In this disclosure, for ease of description, an XYZ coordinate system is established for the anti-collision beam installation tool, where the X direction represents the front-to-back direction, with the side facing the vehicle being front and the opposite side being rear; the Y direction represents the extension direction of each pivot axis from pivot A to pivot I; and the Z direction represents the height direction. Furthermore, it should be noted that when the height direction is vertical, the front-to-back direction can be horizontal. Additionally, it should be noted that the terms used, such as "first" and "second," are used to distinguish one element from another and do not have sequential or importance implications. Furthermore, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements. The above definitions are for explanation and illustration only and should not be construed as limiting this disclosure.

[0020] According to the first aspect of this disclosure, reference to Figures 1 to 6 As shown, the anti-collision beam installation tool includes a clamping mechanism 100, a lifting mechanism 200, and a traveling mechanism 300. The clamping mechanism 100 includes a first clamping part 110 and a second clamping part 120. The first clamping part 110 is rotatably arranged around a first pivot axis so as to be able to approach or move away from the second clamping part 120 to clamp or release the anti-collision beam. At least one of the first clamping part 110 and the second clamping part 120 is provided with a limiting structure for restricting the movement of the anti-collision beam in the front-back direction. The clamping mechanism 100 is disposed on the lifting mechanism 200, which is used to drive the clamping mechanism 100 to move in the height direction. The lifting mechanism 200 is disposed on the traveling mechanism 300, which is used to drive the lifting mechanism 200 to move. The first pivot axis, the front-back direction, and the height direction are perpendicular to each other.

[0021] Through the above-described technical solution, namely the anti-collision beam installation tool of this disclosure, at least one of the first clamping part 110 and the second clamping part 120 is provided with a limiting structure for restricting the forward and backward movement of the anti-collision beam. The limiting structure provides active constraint in the forward and backward direction to prevent the anti-collision beam from slipping due to inertia when it suddenly stops or turns. Therefore, when the anti-collision beam is clamped, it is constrained both in the height direction and in the forward and backward direction, avoiding swaying and displacement of the anti-collision beam during handling or positioning, and improving the stability of clamping.

[0022] Understandably, the clamping mechanism 100 is fixed to the lifting mechanism 200, which drives it to move precisely along the height direction; the lifting mechanism 200 is also mounted on the traveling mechanism 300, which provides omnidirectional movement support. In addition, the first pivot axis, the front-rear direction, and the height direction are all orthogonal to each other, forming a spatial rectangular coordinate system (X / Y / Z axes coordinated), ensuring that the clamping posture is strictly aligned with the vehicle body mounting reference.

[0023] In some embodiments, reference Figure 2 and Figure 6 As shown, the first clamping part 110 includes a first clamping body 111, and the limiting structure includes a first limiting part 112 connected to the front end of the first clamping body 111. The first clamping body 111 and the first limiting part 112 are arranged in an L-shape, and the first limiting part 112 is used to stop in front of the anti-collision beam; and / or, the second clamping part 120 includes a second clamping body 121, and the limiting structure includes a second limiting part 122 and a third limiting part 123. The second limiting part 122 and the third limiting part 123 are spaced apart on the second clamping body 121 in the front-rear direction. The second limiting part 122 is located in front of the third limiting part 123, and the second limiting part 122 and the third limiting part 123 are used to stop in front and rear sides of the anti-collision beam. The second limiting part 122 and the third limiting part 123 are arranged at intervals along the front-back direction. Together with the first clamping body 111 and the first limiting part 112 arranged in an L-shape, they form a multi-faceted constraint on the anti-collision beam. This not only restricts the movement of the anti-collision beam along the height direction, but also restricts the movement of the anti-collision beam along the front-back direction, so that the anti-collision beam will not slip off due to external force when clamped, thereby enhancing the clamping stability and anti-dislodgement capability.

[0024] It is understood that both the first clamping part 110 and the second clamping part 120 have a scratch-resistant protective layer on their working surfaces that contact the anti-collision beam. This scratch-resistant protective layer is polished, resulting in a surface roughness significantly lower than that of the anti-collision beam. Simultaneously, the hardness of the scratch-resistant protective layer is lower than that of the anti-collision beam. When the anti-collision beam receives clamping force, the scratch-resistant protective layer deforms, appropriately reducing the pressure on the surface of the anti-collision beam, ensuring that there are no visible indentations on the surface of the anti-collision beam after clamping and assembly. It is understood that the scratch-resistant protective layer includes, but is not limited to, high-molecular-weight wear-resistant materials, such as polytetrafluoroethylene (PTFE) and polyurethane elastomers.

[0025] In some embodiments, reference Figure 6 As shown, the first limiting part 112, the second limiting part 122 and the third limiting part 123 cooperate to construct at least five constraint surfaces that restrict the movement of the anti-collision beam, including: a first constraint surface (S1) on the first clamping body 111, a second constraint surface (S2) on the first limiting part 112, a third constraint surface (S3) on the second limiting part 122, a fourth constraint surface (S4) on the second clamping body 121 and a fifth constraint surface (S5) on the third limiting part 123. The first constraint surface (S1) (lower surface of the first clamping body 111) and the fourth constraint surface (S4) (upper surface of the second clamping body 121) restrict translation along the Z direction; the second constraint surface (S2) (inner surface of the first limiting part 112), the third constraint surface (S3) (working surface of the second limiting part 122) and the fifth constraint surface (S5) (vertical surface of the third limiting part 123) work together to restrict translation along the X direction; the five constraint surfaces work together to restrict the rotation of the anti-collision beam around the X, Y and Z axes and the translation along the X and Z axes, thus achieving five degrees of freedom constraints.

[0026] In some embodiments, the clamping mechanism 100 further includes a first handle 131, a first connecting rod 132, a second connecting rod 133, a first support frame 141, a support beam 142, and a second column 213; the first support frame 141 and the support beam 142 are connected to the second column 213 at intervals along the height direction, the second clamping part 120 is connected to the support beam 142, the first handle 131 is hinged to the first support frame 141 and can rotate about the A-axis, one end of the first connecting rod 132 is hinged to the first handle 131 and can rotate about the B-axis, and the other end is hinged to the second connecting rod 133 and can rotate about the C-axis, one end of the second connecting rod 133 is hinged to the first support frame 141 and can rotate about the D-axis, and the other end is fixed to the first clamping part 110, the first handle 131 is used to drive the second connecting rod 133 and the first clamping part 110 to rotate through the first connecting rod 132, wherein the D-axis is the first pivot axis, and the A-axis, B-axis, C-axis and D-axis are parallel. The first support frame 141 and the support beam 142 are connected at intervals along the height direction to the second column 213, forming a bending-resistant frame to ensure the stability of the clamping mechanism 100. The first handle 131 rotates around the A-axis as input, driving the first connecting rod 132 to push the second connecting rod 133, which in turn drives the first clamping part 110 to rotate around the D-axis. The second connecting rod 133 is fixedly connected to the first clamping part 110 to form a rigid output end. The parallel arrangement of each hinge axis (A / B / C / D) ensures that the motion trajectory is an ideal arc.

[0027] Understandably, through the synergistic lever principle of the first handle 131, the first connecting rod 132, and the second connecting rod 133, when the first connecting rod 132 moves to a position coinciding with the first handle 131 along the height direction, the mechanism consisting of the first handle 131, the first connecting rod 132, and the second connecting rod 133 reaches its dead point, locking the anti-collision beam and eliminating the risk of workpiece detachment associated with traditional clamps. When the operator applies a backward force to the first handle 131, the first connecting rod 132 passes the dead point, the first clamping part 110 rotates and opens around the D-axis, and the anti-collision beam is released.

[0028] In some embodiments, the walking mechanism 300 includes a support frame 320, and the lifting mechanism 200 includes a first column 211, a second support frame 212, a second handle 221, a fixed hinge 222, a third link 223, a fourth link 224, and a fifth link 225; the first column 211 is disposed on the support frame 320, and the second support frame 212 is disposed on the first column 211; the second handle 221 is hinged to the second support frame 212 and can rotate about the E-axis, and one end of the fixed hinge 222 is fixedly connected to the second column 213, and the other end is hinged to the fifth link 225. 25. One end of the third link 223 is hinged to the second handle 221 and can rotate around the F axis, and the other end is hinged to the fourth link 224 and can rotate around the G axis. One end of the fourth link 224 is hinged to the second support frame 212 and can rotate around the H axis, and the other end is hinged to the fifth link 225 and can rotate around the I axis. The second handle 221 is used to drive the fixed hinge seat 222 and the second column 213 to move along the height direction through the third link 223, the fourth link 224 and the fifth link 225. The E axis, F axis, G axis, H axis and I axis are parallel.

[0029] The second handle 221, with the E-axis as its fulcrum, establishes a force-saving lever. Its rotation drives the third link 223 to push the fourth link 224. The fourth link 224 oscillates around the H-axis on the second support frame 212, driving the fifth link 225 to rotate around the fixed hinge seat 222. The end of the fifth link 225 is fixedly connected to the second column 213, converting the rotational motion into linear displacement in the Z-direction. This constructs a motion transmission chain of "second handle 221 → third link 223 → fourth link 224 → fifth link 225 → second column 213 → clamping mechanism 100 → anti-collision beam," enabling the anti-collision beam to move along the Z-direction, facilitating precise alignment with the anti-collision beam mounting holes. One end of the fixed hinge seat 222 is fixedly connected to the second column 213, and the other end is hinged to the fifth link 225, forming a force closed loop, which linearizes the rotational motion into Z-axis movement; the linkage mechanism of the lifting mechanism 200 constructs a planar motion chain through five pivot axes E, F, G, H and I, which is compact and simpler in structure compared to hydraulic system and gear system.

[0030] In some embodiments, the fifth link 225 is provided with a plurality of hinge holes arranged in an array, and the fixed hinge seat 222 and the fourth link 224 can be hinged to any two different hinge holes. By selecting hinge combinations of the fixed hinge seat 222 and the fourth link 224 at different hole positions, the initial height of the clamping mechanism 100 can be adjusted simply by changing the connection hole positions. This design, while ensuring a fixed lifting stroke, allows for an adjustable initial position of the clamping mechanism 100 along the Z-direction; correspondingly, the endpoint position of the clamping mechanism 100 along the Z-direction is also adjustable. It is understood that the number of hinge holes arranged in an array on the fifth link 225 is not limited.

[0031] In some embodiments, the lifting mechanism 200 further includes a guide structure for guiding the movement of the clamping mechanism 100 along the height direction. The guide structure includes a slider 231 and a slide rail 232 that are slidably engaged. The slider 231 is connected to the first column 211, and the slide rail 232 is connected to the second column 213. The slider 231 and the slide rail 232 form a sliding kinematic pair through a sliding working surface. This kinematic pair provides rigid guiding constraint on the lifting trajectory of the clamping mechanism 100. The slider 231 is fixedly connected to the first column 211, and the slide rail 232 is fixedly connected to the second column 213. This design can constrain five degrees of freedom except for the Z-direction movement. This structure eliminates lateral sway during the lifting process, ensures that the anti-collision beam always moves along the Z-direction, avoids misalignment of the mounting holes due to trajectory deviation, and improves positioning accuracy.

[0032] In some embodiments, the number of second clamping portions 120 is at least two, and they are arranged at intervals along the extension direction of the support beam 142. For the anti-collision beam, which is a slender member with a length dimension significantly greater than its width and height, the multi-point support and clamping design ensures that the load is evenly distributed along the entire length of the anti-collision beam, effectively suppressing the cantilever beam effect caused by its own weight or vibration. Each clamping portion independently constrains its local degrees of freedom, synergistically improving the system's bending and torsional stiffness and preventing plastic deformation of the anti-collision beam due to single-point overload.

[0033] In some embodiments, the walking mechanism 300 includes a support frame 320 and a plurality of casters 310 disposed at the bottom of the support frame 320. The casters 310 can ensure that the anti-collision beam installation tool adapts to the undulations of the ground, moves flexibly, and is easy to quickly align with the installation holes of the anti-collision beam.

[0034] In some embodiments, the anti-collision beam installation tool further includes a seat 330 of the support frame 320, which is located behind the lifting mechanism 200 in the front-rear direction. The seat 330 is located behind the lifting mechanism 200, avoiding the operating area of ​​the lifting mechanism 200, and supports the operator in a seated position to operate the lifting mechanism 200 and the clamping mechanism 100 using the first handle 131 and the second handle 221. The height of the seat 330 matches the elbow height of a seated person, reducing labor intensity.

[0035] It should be noted that although modern automotive assembly lines generally employ fully automated equipment, the anti-collision beam installation tool of this application exhibits irreplaceable advantages in specific scenarios. For example, in vocational school practical training, students can understand the principles of force transmission (such as torque conversion and constraint positioning) through intuitive manual lever operation. This visualization of the physical process is a teaching value that closed automated equipment cannot provide. In addition, the tool's cost is only one-tenth of that of an automated system, significantly reducing the equipment investment cost of training bases. Furthermore, it is particularly crucial in the after-sales repair field. Accident vehicle repair often faces deviations in installation hole positions due to frame deformation. This tool compensates for these deviations in real time through mechanical fine-tuning mechanisms (such as hinge hole position switching and clamping arm angle adjustment), avoiding adaptation failures caused by fixed programming in automated equipment. It also meets the needs of field emergency rescue—in environments without power supply, the purely mechanical structure allows for immediate use after installation, solving the equipment support problem in remote areas.

However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0037] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0038] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
