Description

Technical Field

[0001] This utility model belongs to the field of automotive chassis tie rod assembly technology, and more specifically, it relates to an automotive chassis tie rod clamping assembly fixture. Background Technology

[0002] In the automotive manufacturing industry, chassis tie rods are key components, and their assembly quality directly affects the performance and safety of the entire vehicle. The traditional process of assembling rubber bushings for automotive chassis tie rods has many drawbacks.

[0003] Traditionally, the assembly of rubber sleeves has required manual operation. Workers first place the sleeve into the ball joint assembly slot, a process demanding extremely high concentration. Because the assembly slot is relatively small, even slight miscalculations during manual placement can result in the sleeve being misaligned, affecting subsequent assembly accuracy. After manual placement, specialized pressing equipment is used to further press the sleeve into place. During this process, the pressing action generates considerable impact, and even slight negligence could result in worker fingers being crushed.

[0004] This traditional assembly method is not only inefficient and highly dependent on the skill level of workers, but also carries a high risk of safety hazards. Utility Model Content

[0005] The purpose of this utility model is to provide a tooling for clamping and assembling automotive chassis tie rods, which aims to solve the problems of low efficiency, heavy reliance on worker skill, and high potential safety risks associated with manual assembly of rubber sleeves.

[0009] In one possible implementation, a slide rail is longitudinally arranged at the center of the front side of the longitudinal mounting plate, and a slider is arranged at the rear side of the movable frame, the slider being slidably mounted on the slide rail.

[0010] In one possible implementation, clearance slots are provided on both sides of the movable frame, and the bidirectional cylinder is used to synchronously drive the two clamping components to move along the clearance slots respectively.

[0011] In one possible implementation, the clamping assembly includes a drive block, a connecting portion, and a clamping plate.

The drive block passes through the clearance groove and extends to the bottom of the movable frame. The connecting portion is disposed at the bottom of the inner side of the drive block. The clamping plate is installed on the inner side of the connecting portion. The two clamping plates are used to jointly clamp the rubber sleeve.

[0012] In one possible implementation, the inner end of the clamping plate is connected from bottom to top with a clamping notch and a clearance notch, the two clamping notches are used to clamp the opposite sides of the upper part of the rubber sleeve, and the two clearance notches form a clearance channel for providing passage for the pressing assembly.

[0013] In one possible implementation, the inner wall of the clamping notch is provided with an elastic layer.

[0014] In one possible implementation, the pressing assembly includes a pressing cylinder and a pressing end, wherein the upper cylinder body of the pressing cylinder is fixed to the middle of the lower end face of the movable frame, and the pressing end is disposed at the lower drive end of the pressing cylinder.

[0015] In one possible implementation, the lower end of the pressing end has a spherical end, the outer diameter of which is smaller than the inner diameter of the rubber sleeve.

[0027] Please see Figures 1 to 5 The present invention provides a description of the automotive chassis tie rod clamping and assembly fixture. The automotive chassis tie rod clamping and assembly fixture includes a worktable 1. A support platform 2 and a mounting bracket are provided on the upper surface of the worktable 1. A conformal positioning groove for placing the tie rod is formed on the upper surface of the support platform 2. The mounting bracket is located behind the support platform 2. A hydraulic cylinder 7 is mounted on the top of the mounting bracket. A movable frame 8 is connected to the lower drive end of the hydraulic cylinder 7. A bidirectional cylinder 9 is provided on the upper surface of the movable frame 8. Clamping components are connected to the drive ends of the left and right ends of the bidirectional cylinder 9, respectively. The two clamping components are located on the left and right sides below the movable frame 8. The bidirectional cylinder 9 is used to drive the two clamping components to move relative to each other to clamp the rubber sleeve. A pressing component is provided in the middle of the lower surface of the movable frame 8. The pressing component is located directly above the conformal positioning groove and is used to press the clamped rubber sleeve into the ball joint assembly groove of the tie rod.

[0028] Compared with the prior art, the automotive chassis tie rod clamping assembly fixture provided by this utility model has a support platform 2 and a mounting bracket installed on the upper surface of the workbench 1 from front to back. A conformal positioning groove is opened on the upper surface of the support platform 2. A hydraulic cylinder 7 is set on the top of the mounting bracket. The lower drive end of the hydraulic cylinder 7 is connected to a movable frame 8. A double-acting cylinder 9 is set on the upper surface of the movable frame 8. The drive ends of the left and right ends of the double-acting cylinder 9 are respectively connected to clamping components. A pressing component is set in the middle of the lower surface of the movable frame 8. When using the automotive chassis tie rod clamping assembly fixture provided by this utility model, the tie rod is first placed horizontally in the conformal positioning groove. Then, the double-acting cylinder 9 is used to synchronously drive the two clamping components to clamp the rubber sleeve. The hydraulic cylinder 7 drives the movable frame 8 to move downward so that the lower part of the rubber sleeve is placed in the ball joint assembly groove. The pressing component presses the rubber sleeve in the clamped state into the ball joint assembly groove of the tie rod. The automotive chassis tie rod clamping assembly fixture provided by this utility model can significantly improve assembly efficiency, eliminate the influence of worker skill level, and avoid safety risks.

[0029] Workbench 1, serving as the foundational load-bearing structure of the entire fixture, is constructed from high-strength alloy steel, possessing excellent rigidity and stability. Its upper surface undergoes high-precision milling, with flatness errors controlled within an extremely small range, providing a flat and reliable reference surface for the installation of support platform 2 and mounting bracket. Adjustable-height anchor bolts are installed at the bottom of workbench 1, which not only adapts to differences in the flatness of different workshop floors, ensuring the entire fixture remains level, but also effectively reduces the transmission of vibrations from the ground, guaranteeing that the assembly process's precision is not affected by external factors.

[0030] Please see Figure 1 and Figure 2The conformal positioning groove includes an end positioning groove 5 and a rod positioning groove 6. The end positioning groove 5 is located in the middle of the upper end face of the support platform 2, and the rod positioning groove 6 is located on the upper end face of the support platform 2. One end of the rod positioning groove 6 connects to the end positioning groove 5, and the other end extends to the side wall of the support platform 2. The outer diameter of the end positioning groove 5 decreases from top to bottom. This shape, which is wider at the top and narrower at the bottom, can effectively limit the horizontal displacement of the end of the pull rod, ensuring that it is always stably in the ideal position during assembly without any deviation, laying a solid foundation for subsequent rubber assembly operations. In addition, the decreasing outer diameter design also allows operators to more quickly and intuitively find the placement position by sight and touch when placing the pull rod, greatly improving the preparation efficiency in the early stage of assembly and ensuring that the rod is properly fixed throughout the assembly process. The bottom of the rod positioning groove 6 has an arc-shaped groove. This arc-shaped groove design perfectly matches the circular cross-section of the rod, greatly increasing the contact area and dispersing the pressure from the rod's own weight. This not only prevents damage to the surface of the support platform 2 due to excessive local pressure but also further enhances the stability of the rod placement. Moreover, during assembly, when fine-tuning or rotating the rod is required, the arc-shaped groove provides smooth support, making the operation smoother and reducing assembly errors caused by friction and jamming. This comprehensively improves the practicality and assembly accuracy of the automotive chassis rod clamping assembly fixture.

[0031] The support platform 2, located on the upper surface of the workbench 1, is a key component for positioning the chassis tie rod. Its upper surface features a conformal positioning groove, consisting of an end positioning groove 5 and a rod positioning groove 6. The end positioning groove 5 is located in the middle of the upper surface of the support platform 2, with its outer diameter decreasing from top to bottom. This design guides the end of the chassis tie rod into accurate positioning and firmly restrains it horizontally to prevent displacement. One end of the rod positioning groove 6 connects to the end positioning groove 5, and the other end extends to the side wall of the support platform 2. Its bottom arc-shaped groove perfectly matches the shape of the tie rod, increasing the contact area with the tie rod, improving positioning stability, and facilitating fine-tuning of the tie rod during assembly.

[0032] Please see Figure 1 and Figure 2 The mounting bracket includes a longitudinal mounting plate 3 and a transverse mounting plate 4. The longitudinal mounting plate 3 is vertically mounted on the upper end face of the support platform 2 and located on the rear side of the support platform 2. The transverse mounting plate 4 is horizontally mounted on the upper end of the longitudinal mounting plate 3 and extends horizontally forward. The upper cylinder body of the hydraulic cylinder 7 is vertically mounted on the upper end face of the transverse mounting plate 4, and the lower drive end of the hydraulic cylinder 7 longitudinally penetrates the transverse mounting plate 4.

[0033] The mounting frame serves as the power support and transmission hub for the entire tooling setup. It comprises a longitudinal mounting plate 3 and a transverse mounting plate 4. The longitudinal mounting plate 3 is vertically positioned on the rear side of the upper end face of the support platform 2, providing vertical support and positioning for the entire mounting frame. It is tightly connected to the support platform 2 using high-strength bolts. The transverse mounting plate 4 is horizontally fixed to the upper end of the longitudinal mounting plate 3 and extends horizontally forward, forming a stable cantilever structure. This structural design ensures sufficient space to keep the operating area below unobstructed while providing a reliable mounting platform for the hydraulic cylinder 7 above.

[0034] Hydraulic cylinder 7 serves as the core of the tooling's power output, with its upper cylinder body vertically mounted on the upper surface of the transverse mounting plate 4. To ensure the verticality and stability of the hydraulic cylinder 7's installation, the mounting portion of the transverse mounting plate 4 perfectly aligns with the mounting surface of the hydraulic cylinder 7's cylinder body and is secured with multiple high-strength bolts. The lower drive end of the hydraulic cylinder 7 longitudinally penetrates the transverse mounting plate 4, providing stable and precise axial thrust during operation. Internally, it employs piston sealing technology and piston rod machining processes, effectively reducing hydraulic oil leakage, ensuring stable output of driving force, and simultaneously improving the wear resistance and service life of the piston rod.

[0035] The movable frame 8, connected below the horizontal mounting plate 4, can move precisely vertically under the drive of the hydraulic cylinder 7. A two-way cylinder 9 is mounted on the upper surface of the movable frame 8, with clamping components connected to its left and right driving ends. The two-way cylinder 9 can precisely control the relative movement of the two clamping components, thereby achieving stable clamping of the rubber sleeve. A pressing component is located in the middle of the lower surface of the movable frame 8. When the pressing component descends with the movable frame 8 to the appropriate position, it can precisely press the clamped rubber sleeve into the ball joint assembly groove of the automotive chassis tie rod.

[0036] A slide rail 10 is longitudinally mounted on the center of the front side of the longitudinal mounting plate 3, and a slider is mounted on the rear side of the movable frame 8, sliding on the slide rail 10. The slide rail 10 is manufactured using high-precision machining technology, and its surface is hardened by quenching, resulting in extremely high hardness and wear resistance. The straightness error of the slide rail 10 is extremely small, ensuring smooth and precise movement. A corresponding slider is mounted on the rear side of the movable frame 8, perfectly matching the slide rail 10 with a high-precision sliding fit. This combination of slider and slide rail 10 provides precise guidance and stable support for the vertical movement of the movable frame 8.

[0037] The movable frame 8 has clearance slots 11 on both sides, and a bidirectional cylinder 9 is used to synchronously drive the two clamping components to move along the clearance slots 11 respectively. The clearance slots 11 provide space for the movement of the clamping components, and the bidirectional cylinder 9 on the upper surface of the movable frame 8 can synchronously drive the two clamping components to move relative to each other along the clearance slots 11. The bidirectional cylinder 9 has high-precision motion control capability and can accurately adjust the moving distance and speed of the clamping components.

[0038] Please see Figure 3 and Figure 4 The clamping assembly includes a drive block 12, a connecting part 13, and a clamping plate 14. The upper end of the drive block 12 is connected to the drive end on the same side as the bidirectional cylinder 9. The drive block 12 passes through the clearance groove 11 and extends to the bottom of the movable frame 8. The connecting part 13 is located at the bottom of the inner side of the drive block 12. The clamping plate 14 is installed on the inner side of the connecting part 13. The two clamping plates 14 are used to clamp the rubber sleeve together.

[0039] The bidirectional cylinder 9 serves as the power source, with its drive end on the same side tightly connected to the upper end of the drive block 12. When the bidirectional cylinder 9 starts working, it can precisely drive the drive block 12 to perform corresponding actions. The drive block 12 passes through the clearance groove 11 on the moving frame 8 and extends smoothly to the bottom of the moving frame 8. This structure ensures that the drive block 12 will not interfere with the moving frame 8 during movement, guaranteeing the smooth operation of the entire device. The connecting part 13 located at the bottom of the inner side of the drive block 12 plays a crucial transitional role. On the one hand, it stably receives the power transmission from the drive block 12, and on the other hand, it provides a reliable mounting point for the clamping plate 14. The construction of the connecting part 13 needs to fully consider mechanical performance to ensure that there will be no loosening or deformation during clamping, ensuring effective force transmission. The clamping plate 14 is installed on the inner side of the connecting part 13, and the two clamping plates 14 cooperate with each other. In actual operation, when the bidirectional cylinder 9 drives the drive block 12 to move, the two clamping plates 14 move synchronously towards or away from each other through the connecting part 13. When moving towards each other, the two clamping plates 14 can stably clamp the rubber sleeve together, and the clamping force must be moderate to ensure that the rubber sleeve does not shift or fall off in subsequent processes, while also preventing damage to the rubber sleeve due to excessive clamping force. When moving away from each other, the rubber sleeve can be released, completing one full clamping cycle. This process is repeated to meet the needs of the production line for frequent clamping operations of the rubber sleeve.

[0040] Please see Figure 3The clamping plate 14 has a clamping notch 15 and a clearance notch 16 connected sequentially from bottom to top on one inner end. The two clamping notches 15 are used to clamp the opposite sides of the upper part of the rubber sleeve, and the two clearance notches 16 form a clearance channel for the passage of the pressing component. The clamping notches 15 and clearance notches 16 are machined sequentially from bottom to top on one inner end of the clamping plate 14. The clamping notches 15 on the two clamping plates 14 are arranged opposite each other. When the bidirectional cylinder 9 drives the drive block 12 to move the two clamping plates 14 toward each other, the two clamping notches 15 can accurately clamp the opposite sides of the upper part of the rubber sleeve. The shape and size of the clamping notch 15 are customized according to the shape and size of the upper part of the rubber sleeve, usually an arc or polygon matching the contour of the upper part of the rubber sleeve, to ensure sufficient contact area during clamping, evenly distribute the clamping force, and avoid deformation or damage to the rubber sleeve due to uneven force. Meanwhile, to increase clamping stability, the surface of the clamping notch 15 can be treated with an anti-slip finish, such as knurling or attaching anti-slip rubber pads. The clearance notches 16 on the two clamping plates 14 are also positioned opposite each other. When the two clamping plates 14 are in the clamping position of the rubber sleeve, the two clearance notches 16 together form a clearance channel for the passage of the pressing assembly. The dimensions of the clearance notch 16 need to be designed according to the external dimensions of the pressing assembly to ensure that the pressing assembly can pass smoothly without colliding with the clamping plates 14 during passage. The pressing assembly is typically used for further pressing operations on the rubber sleeve, such as pressing the rubber sleeve into a specific installation position. In actual operation, after the rubber sleeve is clamped within the clamping notch 15, the pressing assembly can descend along the clearance channel, applying downward pressure to the rubber sleeve to complete the corresponding assembly process.

[0041] Preferably, the inner wall of the clamping notch 15 is provided with an elastic layer 17. The elastic layer 17 can be made of materials with good elasticity and wear resistance, such as rubber or silicone, and is fixed to the inner wall of the clamping notch 15 by processes such as bonding or injection molding. The elastic layer 17 can further enhance the clamping stability of the rubber sleeve, forming a tighter fit on the surface of the rubber sleeve and preventing it from slipping during clamping. On the other hand, it can buffer the clamping force and avoid causing hard damage to the surface of the rubber sleeve, which is especially suitable for rubber sleeves with easily scratched surfaces or soft textures.

[0042] The pressing assembly includes a pressing cylinder 18 and a pressing end 19. The upper cylinder body of the pressing cylinder 18 is fixed to the middle of the lower end face of the moving frame 8, and the pressing end 19 is located at the lower drive end of the pressing cylinder 18. The pressing cylinder 18 and the moving frame 8 can be fixed by bolts or welding to ensure that the pressing cylinder 18 does not shift or shake during operation. The lower end of the pressing end 19 has a spherical end, the outer diameter of which is smaller than the inner diameter of the rubber sleeve. This design allows the pressing end 19 to be easily aligned with the center of the rubber sleeve when it approaches it, reducing the difficulty of the pressing operation and improving the accuracy of the pressing. At the same time, the curved surface design of the spherical end helps guide the deformation of the rubber sleeve during the pressing process, allowing the rubber sleeve to be subjected to force more evenly, thus being pressed into the designated position more smoothly and reducing the risk of damage to the rubber sleeve due to excessive local force. The pressing end 19 is made of high-strength, wear-resistant metal material and undergoes a special heat treatment process to further improve its hardness and wear resistance, so as to adapt to frequent pressing operations and extend the service life of the pressing end 19.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
