Description

Technical Field

[0001] This invention relates to the field of front suspension assembly tooling technology, and in particular to a multi-functional front suspension support device for chassis assembly. Background Technology

[0002] Currently, the installation of the front suspension in the final chassis assembly process remains a significant challenge in the industry. Although tooling assistance is available, manual installation is still the primary method, representing a semi-automatic assembly approach. A major difficulty with front suspension tooling lies in compatibility. Different vehicle models have varying front wheel spacing and brake disc spacing, making existing tooling unsuitable for brake discs in different locations. This compatibility issue poses a substantial challenge to front suspension tooling, hindering installation and significantly impacting efficiency. Furthermore, during the lifting process, the product design may encounter obstacles such as brake pipe supports, wheel speed sensor supports, or frame flanges along the upward installation path. In such cases, the upward installation is not linear; it requires a "Z" shaped path. However, existing tooling often follows a linear path, leading to potential interference issues.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0066] Please refer to Figures 1 to 7 The present invention provides a multi-functional front suspension support device for chassis assembly, which mainly includes a first base 10, a second base 20, a brake disc support mechanism 30, a front suspension rotation positioning mechanism 40, a front suspension support mechanism 50, a slide rail 60, and a positioning block 70.

[0067] The first base 10 is a support structure used to support the brake disc support mechanism 30 and the front suspension rotation positioning mechanism 40.

[0068] The brake disc support mechanism 30 is disposed on the first base 10 to support the brake disc. That is, when the front suspension is installed, it can limit and support the brake disc of the front suspension, and at the same time limit the front suspension. In this exemplary embodiment, the brake disc support mechanism 30 is inserted into the first base 10, and the insertion direction is from top to bottom. This facilitates the quick replacement of the brake disc support mechanism 30. By adopting a plug-in structure, different brake disc support mechanisms 30 can be quickly replaced, thereby switching according to different vehicle models and adapting to different vehicle models to achieve support for front suspensions of different heights. The top of the brake disc support mechanism 30 is provided with a support block. A U-shaped groove 31 is opened on the top surface of the support block. By providing the U-shaped groove 31, it cooperates with the brake disc to limit the forward and backward movement of the front suspension. At the same time, the outer side of the support block can achieve Y-direction limitation, restricting the Y-direction movement of the brake disc. The Y-direction of this invention refers to the direction consistent with the extension direction of the slide rail 60.

[0069] A slide rail 60 is disposed at the bottom of the first base 10 so that the first base 10 can move on the slide rail 60. In implementation, the slide rail 60 is fixed to the ground or other supporting structure and does not move. At this time, the first base 10 can move on the slide rail 60, that is, the first base 10 can move to a certain position on the slide rail 60. The slide rail 60 adopts a combination of a slider and a track. Either the slider or the track can be fixed to the first base 10. In this exemplary embodiment, the track is fixed to the first base 10, and the slider is fixed to the ground or other supporting structure.

[0070] The positioning block 70 is disposed next to the first base 10. During implementation, the positioning block 70 is fixed to the ground or other supporting structure and does not move. The positioning block 70 is provided with two or more positioning ports 71 along the extension direction of the slide rail 60. The number of positioning ports 71 is mainly based on the number of vehicle models to be adapted. For example, in this exemplary embodiment, there are two positioning ports 71, mainly to accommodate two vehicle models.

[0071] A limiting rod 11 is provided on the first base 10. The limiting rod 11 is rotatably configured so that when the first base 10 moves along the slide rail 60, it can be aligned with one of the positioning ports 71 of the positioning block 70 and can be engaged in the positioning port 71. At this time, when the first base 10 moves along the slide rail 60 to a certain position and the limiting rod 11 is aligned with one of the positioning ports 71, the limiting rod 11 is engaged in the positioning port 71. At this time, the first base 10 cannot move, that is, the first base 10 and the brake disc support mechanism 30 on it are fixed in a certain position.

[0072] The front suspension rotation positioning mechanism 40 is set on the first base 10 for positioning the front suspension.

[0073] The second base 20 is a support structure used to support the front suspension support mechanism. The first base 10 and the second base 20 are relatively independent.

[0074] The front suspension support mechanism 50 is located on the second base 20 to support the front suspension.

[0075] When implementing, please refer to Figure 8 and Figure 9 The front suspension support mechanism 50 provides limiting support for the front suspension and also serves as a positioning mechanism. The position of the first base 10 is adjusted according to different vehicle models. By inserting the limiting rod 11 into the corresponding positioning port 71, the first base 10 is fixed, and the brake disc support mechanism 30 on the first base 10 is fixed in a certain position. This allows for the support and limiting of the brake discs of the front suspension of a specific vehicle model. When used on another vehicle model, due to the different distances between the two front wheels, the distance between the brake discs is also different. In this case, the limiting rod 11 is rotated out of the positioning port 71, and the position of the first base 10 is adjusted. The limiting rod 11 then aligns with another positioning port 71. The limiting rod 11 is then inserted into the corresponding positioning port 71, and the first base 10 is fixed. The position of the brake disc support mechanism 30 is adjusted and fixed, enabling it to adapt to the support and limiting of the brake discs of the front suspension of a new vehicle model. The multi-functional front suspension support device for chassis assembly of the present invention can be used for the assembly of front suspension with brake discs in different positions, is compatible with various front wheel distances, has strong compatibility, that is, it can be used for the front suspension installation of multiple vehicle models, saves tooling usage, and improves assembly efficiency.

[0076] In this preferred embodiment, the front suspension rotation positioning mechanism 40 includes a sleeve 41, a sliding member 44, an elastic member, and a positioning rod 45. The sleeve 41 is vertically mounted on the first base 10 and is a cylindrical structure with an open top. The side wall of the sleeve 41 has an axially extending vertical groove 42 and a circumferentially extending annular groove 43. The annular groove 43 is connected to the bottom of the vertical groove 42, and the circumferential angle of the annular groove 43 is 90°. A locking groove 47 is provided upward at the end of the annular groove 43 away from the vertical groove 42. The sliding member 44 is partially fitted inside the sleeve 41. The sliding member 44 can slide axially and rotate circumferentially within the sleeve 41. A bushing is provided at the open top of the sleeve 41, and the bushing is fitted onto the sliding member 44. A handle 46 is provided on the side wall of the sliding member 44. The handle 46 extends through the side wall of the sleeve 41 and can move within the vertical groove 42 or the annular groove 43. For example, when the sliding member 44 slides axially up and down within the sleeve 41, the handle 46 moves up and down along the vertical groove 42; when the sliding member 44 rotates circumferentially within the sleeve 41, the handle 46 rotates circumferentially along the annular groove 43. The elastic element is preferably a gas spring, which is located inside the sleeve 41, between the bottom of the sliding member 44 and the bottom of the sleeve 41, so that the sliding member 44 has an upward tendency. A positioning rod 45 is provided at the top of the sliding member 44 for positioning; in implementation, it is connected to the front suspension to achieve positioning. In a preferred embodiment, the positioning rod 45 includes a lower positioning rod 451, an upper positioning rod 453, and a connecting rod 452. The lower positioning rod 451 is vertically positioned on top of the sliding member 44, and the upper positioning rod 453 is vertically positioned above the lower positioning rod 451, with the projections of the upper positioning rod 453 and the lower positioning rod 451 not overlapping. The connecting rod 452 connects the upper positioning rod 453 and the lower positioning rod 451 at its two ends, respectively. The upper positioning rod 453 is used to connect with the front suspension. In implementation, when the part is placed on the tray, the sliding member 44 and the positioning rod 45 are lifted up under the action of the elastic member (e.g., Figure 3 As shown), the front suspension is in a positioning state to ensure it does not rotate and maintains its posture (the front suspension has holes corresponding to the upper positioning rod 453); after assembly is completed and the front suspension is fixed to the vehicle body, the sliding part 44 and the positioning rod 45 are compressed to a retracted state along the vertical groove 42 by the handle 46 on the tooling, and rotated along the annular groove 43, thereby achieving rotation (at this time, as shown) Figure 4 As shown in the figure, the front suspension upper block is rotated and positioned by means of a retractable and rotatable mechanism 40.

[0077] The front suspension support mechanism 50 includes a support base 51, a support column 52, a support top seat 53, a flipping part 54, and an upper clamping head 55. The support base 51 is mounted on the second base 20, the support column 52 is mounted on the support base 51, and the support top seat 53 is mounted on the support column 52. The flipping part 54 is rotatably mounted on the support top seat 53. The support top seat 53 is provided with a flipping shaft 56, which is connected to the flipping part 54 via a flipping shaft 57, enabling the flipping part 54 to flip. When the flipping part 54 rotates to a horizontal position, it abuts against the support top seat 53 and cannot continue to flip downwards. Because it cannot continue to flip downwards, it has a certain supporting capacity to support the front suspension. The upper clamping head 55 is detachably mounted on the flipping part 54 and is used to clamp the front suspension, achieving axial clamping and limiting of the front suspension and providing support for the front suspension. Different car models have different front suspensions. Therefore, the detachable, quick-change upper clamping head of the tooling allows for quick changes to ensure compatibility with different car models. When the part is placed on the pallet, the flipping part 54 is rotated to a horizontal position (e.g., ...). Figure 5 (As shown in the image), at this position, the flipping part 54 is at a 90° angle to the upright posture, keeping the part in a clamped posture and clamping it (without locking it). After assembly, when the pallet and the overall mechanism fall, the upper clamping head 55 is subjected to an upward force, which will push the flipping part 54 to rotate upward 90° around the flipping axis 56, maintaining a vertical posture, thereby disengaging the upper clamping head 55 from the part, ensuring a smooth descent of the pallet and the overall mechanism, and achieving automatic disengagement of the upper clamping head 55.

[0078] A tension spring 56 is provided between the flipping part 54 and the support top seat 53 so that the flipping part 54 tends to rotate to a horizontal position. When the upper clamping head 55 disengages from the front suspension, the flipping part 54 can flip to a horizontal position under the action of the tension spring 56, thereby driving the upper clamping head 55 to flip back to the horizontal position, thus achieving automatic reset. In this exemplary embodiment, the upper clamping head 55 includes a mounting plate 551, a first clamping part 552, a second clamping part 553, and a locking pin 554. Mounting plate 551 is detachably mounted on flipping part 54 by bolt connection; first clamping part 552 is fixedly mounted on mounting plate 551; second clamping part 553 is slidably mounted on mounting plate 551. Specifically, the first clamping part 552 is provided with a limiting shaft, the second clamping part 553 has a mating hole, and the limiting shaft partially extends into the mating hole for guidance. The second clamping part 553 and the first clamping part 552 are opposite to each other and slide relative to each other to achieve clamping when they are close together; locking pin 554 is provided on mounting plate 551 to lock the second clamping part 553 onto mounting plate 551. When the locking pin 554 is tightened, it can press against the second clamping part 553, thereby locking the second clamping part 553 onto mounting plate 551. The upper clamping head 55 adopts a single-sided locking form. Through the single-sided movable structure, quick change can be achieved by simply rotating the quick-change locking pin, which can quickly assemble and disassemble the clamping.

[0079] In this exemplary embodiment, the support base 51 includes a lower support base 511, an upper support base 512, an attitude holding rod 513, a first attitude push rod 514, and a second attitude push rod 515. The lower support base 511 is fixedly mounted on the second base 20, and the upper support base 512 is rotatably mounted on the lower support base 511 so that the upper support base 512 can tilt to both sides, i.e., a seesaw-like structure; the attitude holding rod 513 is located on one side of the bottom of the upper support base 512 and can abut against the lower support base 511 to keep the upper support base 512 tilted to a certain position, i.e., at this time, the upper support base 512 can be kept stationary by the support of the attitude holding rod 513; the first attitude push rod 514 is located on one side of the upper support base 512 to hold the upper support base 512 in place when the first attitude push rod 515 is tilted to the side. When the first posture push rod 514 moves upward, it can abut against one side of the upper support base 512. Moving the first posture push rod 514 upward can lift one side of the upper support base 512, causing the upper support base 512 to tilt to the opposite side. The second posture push rod 515 is located beside the other side of the upper support base 512. When the second posture push rod 515 moves upward, it can abut against the other side of the upper support base 512. Moving the second posture push rod 515 upward can lift one side of the upper support base 512, causing the upper support base 512 to tilt to the opposite side. The first posture push rod 514 and the second posture push rod 515 can be driven to rise and fall by cylinders, electric actuators, etc. During assembly, to ensure that the front suspension does not interfere with the vehicle body, the attitude of the front suspension needs to be adjusted. The support device is equipped with attitude adjustment push rods. The first attitude push rod 514 is lifted by cylinders, etc., so that the front suspension tilts to one side. Similarly, the second attitude push rod 515 is lifted by cylinders, etc., so that the front suspension tilts to the other side. This ensures that the path is safely assembled in place without interference. It enables different angle adjustments during the lifting of the front suspension, which rises along a "Z" path, thereby avoiding interference between the front suspension and surrounding parts such as the bracket during the lifting process.
