The automobile ball joint control arm, also known as a swing arm, is an indispensable part of a modern automobile suspension system. It is connected to the wheel and the vehicle body through a ball joint or a bushing, playing a role in force transmission and guiding; the ball joint assembly usually consists of a ball seat and a control arm body, and the assembly methods include embedding, welding, riveting or bolt connection. This structural design enables the ball joint to rotate freely in multiple directions, so as to adapt to various dynamic changes of the wheel during driving.

[0047] As Figures 1 - 3 shown, an automotive aluminum alloy ball joint control arm assembly includes a swing arm body 1. A ball head assembly 2 is assembled inside the tip of the middle part of the swing arm body 1. Swing arm bushing assemblies 3 are assembled inside both ends of the swing arm body 1.

The spherical end of the ball pin 203 is rotatably inserted into the inside of the ball seat 202. A plug seat 204 is clamped on one side of the ball shell 201, and a dust cover is arranged on the other side of the ball shell 201.

[0049] As Figures 4 - 13 shown, an automotive aluminum alloy ball joint control arm assembly modular assembly device includes an assembly machine table 6. A rotating platform 601 for fixedly placing the swing arm body 1 is rotatably assembled on the surface of the assembly machine table 6. A pre-assembly mechanism 7 for pre-assembling the ball head assembly 2 into the swing arm body 1, a press-fitting mechanism 8 for press-fitting the ball head assembly 2 into the swing arm body 1, and a lateral press-fitting mechanism 9 for assembling the swing arm bushing assembly 3 into the inside of both ends of the swing arm body 1 are sequentially arranged on the edge of the surface of the assembly machine table 6.

[0050] Referring to the attached Figure 4 and Figure 9, inside the assembly machine 6, there is a rotating mechanism for controlling the rotation of the rotating platform 601. The swing arm support seats 604 for fixedly placing the swing arm body 1 are arrayed and installed on the surface edge of the rotating platform 601. Ball head support seats 602 for supporting the assembly part of the swing arm body 1 and the ball head assembly 2 are installed on the surface of the rotating platform 601 and outside the swing arm support seats 604.

Bottom supports 603 are installed on the surface of the assembly machine 6 corresponding to the positions of the ball head support seats 602.

[0051] Embodiment 1:

[0052] Refer to the appendix Figures 5 - 8 , at the top of the pre-assembly mechanism 7, a lifting platform 702 is fixedly arranged. In the middle of the pre-assembly mechanism 7, a feeding platform 701 is fixedly arranged. On one side of the surface of the feeding platform 701, a belt feeder 703 for supplementing the ball head assembly 2 is fixedly installed. Above the belt feeder 703, a guide plate 704 for guiding the movement of the ball head assembly 2 is fixedly arranged. On the surface of the feeding platform 701 and on one side of the belt feeder 703, a track machine 705 is slidably assembled. One end of the track machine 705 is fixedly assembled with a sleeve 706 through a connecting rod. Inside the sleeve 706, a material-carrying block 707 for carrying the ball head assembly 2 to move is telescopically assembled. On the surface of the sleeve 706, a cylinder 708 is fixedly assembled, and the output end of the cylinder 708 is fixedly connected to the material-carrying block 707;

[0053] Refer to the appendix Figures 5 - 8 , on the surface of the feeding platform 701 and directly below the lifting platform 702, a clamping table 709 is installed. A through hole 710 is penetrated and opened at the central position of the clamping table 709. Inside the through hole 710, half-groove blocks 711 are symmetrically slidably assembled. On the surfaces of the two half-groove blocks 711, half-material grooves 712 for the ball head assembly 2 to fall into are opened. On both sides inside the clamping table 709, double-threaded screws 713 are rotatably installed. On the side walls of the half-groove blocks 711, screw tubes sleeved on the outer surfaces of the double-threaded screws 713 are fixedly arranged. On one side of the outer wall of the clamping table 709, a power housing 714 is fixedly arranged. Inside the power housing 714, a double-shaft motor for driving the two double-threaded screws 713 to rotate is assembled;

[0054] Refer to the appendix Figures 5 - 8, the telescopic output end of the lifting platform 1 702 is integrally provided with a clamping rod 715, and the edge of the bottom end of the clamping rod 715 is fixedly provided with an inclined groove rail 716 in a circular array, and the bottom of the clamping rod 715 is movably assembled with a clamping block 719 in a circular array, and the clamping block 719 is used to clamp the ball pin 203 when it is aggregated, and the outer wall of the clamping block 719 is integrally provided with a wedge block 720, and the wedge block 720 is slidably assembled inside the corresponding inclined groove rail 716, and the top of the clamping block 719 is fixedly connected with a guide rod 721, and the inside of the clamping rod 715 is fixedly installed with a cylinder 2 717, and the outer wall of the end of the telescopic output end of the cylinder 2 717 is fixedly provided with a straight groove body 718 in an array, and the guide rod 721 movably penetrates the corresponding straight groove body 718.

[0055] According to the above structure, the assembled ball head assembly 2 is arranged in the guide plate 704 of the belt feeder 703. In the process of pre-installing a ball head assembly 2, the belt feeder 703 first moves the ball head assembly 2 to the end of the guide plate 704, and then the cylinder 1 708 operates and controls the movement of the material block 707, and the material block 707 immediately contacts the ball head assembly 2 at the end, and then the track machine 705 operates and pushes the ball head assembly 2 to the clamping table 709, and the ball head assembly 2 immediately falls into the circular material groove composed of the half grooves 712 on the surface of the two half groove blocks 711;

[0056] Then, the lifting platform 1 702 controls the clamping rod 715 to move downward. When its bottom end is close to the ball pin 203, the cylinder 2 717 extends and operates, and each clamping block 719 will be pushed and move together along the inclined groove rail 716. When the clamping blocks 719 gather together, they will clamp the ball pin 203 together. In this process, since the half trough 712 restricts the ball head assembly 2, the clamping block 719 can correct the ball pin 203 at the same time to ensure that the ball pin 203 is perpendicular to the ball shell 201, and it is convenient for the subsequent press-fitting work;

[0057] Finally, the dual-axis motor in the power housing 714 starts and drives the two dual-thread screws 713 to rotate at the same time. At this time, the two half-slot blocks 711 will move away from each other, and then the clamping rod 715 will continue to move downward through the lifting platform 1 702. The clamping rod 715 will carry the ball head assembly 2 through the clamping platform 709 and finally be sent into the corresponding hole of the swing arm body 1;

[0058] In the above process, the swing arm body 1 is transported to the pre-installation mechanism 7 and the press-fitting mechanism 8 in sequence through the rotating platform 601. The pre-installation mechanism 7 can pre-install the ball head assembly 2 into the hole position of the swing arm body 1 one by one, and during the pre-installation process, the ball pin 203 is corrected to ensure that the ball pin 203 is perpendicular to the ball shell 201, which is conducive to the subsequent press-fitting work of the ball head assembly 2 by the press-fitting mechanism 8.

[0059] The working principle of the present invention is as follows: First, the ball head assembly 2 is moved to the end of the guide plate 704 by the belt feeder 703. Secondly, the first cylinder 708 operates and controls the movement of the belt block 707. The belt block 707 then contacts the ball head assembly 2 located at the end. Immediately afterwards, the rail machine 705 operates and pushes the ball head assembly 2 towards the clamping table 709. The ball head assembly 2 then falls into the circular material groove formed by the semi-material grooves 712 on the surfaces of the two semi-groove blocks 711. Subsequently, the first elevator table 702 controls the downward movement of the clamping rod 715. When the bottom end of the clamping rod 715 approaches the ball pin 203, the second cylinder 717 extends and operates. Each clamping block 719 will be pushed and move together along the inclined chute rail 716. While the clamping blocks 719 gather together, they will jointly clamp the ball pin 203. During this process, since the semi-material groove 712 restricts the ball head assembly 2, the clamping blocks 719 can correct the ball pin 203 at the same time, ensuring that the ball pin 203 is perpendicular to the ball shell 201, which is convenient for subsequent press-fitting work. Finally, the double-shaft motor in the power housing 714 starts and simultaneously drives the rotation of the two double-threaded screw rods 713. At this time, the two semi-groove blocks 711 will move away from each other. Subsequently, the first elevator table 702 controls the clamping rod 715 to continue moving downward. The clamping rod 715 will carry the ball head assembly 2 through the clamping table 709 and finally send it into the corresponding hole position of the swing arm body 1.

[0060] Embodiment 2:

[0061] Refer to the attached Figures 10 - 13 , at the top of the lateral press-fitting mechanism 9, a second elevator table 901 is fixedly arranged. The telescopic output end of the second elevator table 901 is integrally provided with a working rod 902, and the end of the working rod 902 is integrally provided with a connecting block 903. Inside the lateral press-fitting mechanism 9 and at the bottom of the second elevator table 901, a semi-tube body 904 is movably assembled. The bottom of the connecting block 903 is fixedly connected with a through rod 905. The through rod 905 slidably penetrates through the middle of the semi-tube body 904 and a first spring 906 is sleeved on its outer surface. On both side walls of the middle part of the semi-tube body 904, straight groove plates 907 are integrally provided, and on both sides of the connecting block 903, guide blocks 908 that movably penetrate through the straight groove plates 907 are integrally provided;

[0062] Refer to the attached Figures 10 - 13, push rods 909 and feeding parts 911 are movably assembled at both ends of the semi-tube body 904, and the push rods 909 are placed inside the feeding parts 911. Both ends of the tapping block 903 are connected to one end of the corresponding push rod 909 through a swing arm 910. A clamping tube plate 912 for sleeving the end of the swing arm body 1 is integrally provided at the edge of the feeding part 911 away from the push rod 909. A bushing groove 913 for placing the swing arm bushing assembly 3 is opened inside the feeding part 911 near one end of the clamping tube plate 912. An inclined plate 916 is integrally provided on the outer wall of the feeding part 911 containing the bushing groove 913. A partition plate 914 is integrally provided in the middle of the feeding part 911. A conduit 915 is fixedly provided on the outer wall of the feeding part 911 near one end of the clamping tube plate 912. One end of the push rod 909 passing through the partition plate 914 and extending into the bushing groove 913 is fixedly provided with a push block 917. Guide posts 918 are fixedly connected to the outer walls on both sides of the push block 917. The guide posts 918 pass through the corresponding conduits 915 and a second spring 919 is sleeved on the outer surface;

[0063] Refer to the appendix Figures 10 - 13 , a replenishing material rack 920 is fixedly installed on the side wall at the bottom of the elevator platform two 901 of the lateral pressing mechanism 9. Aggregate shells 921 for collecting the swing arm bushing assemblies 3 are integrally provided at both ends inside the replenishing material rack 920. A discharge chute 922 is integrally provided at the bottom end of the aggregate shell 921. A rectangular frame 923 is elastically and slidably assembled at the end of the discharge chute 922. An upper baffle 924 is integrally provided obliquely above the rectangular frame 923. A lower baffle 925 is integrally provided obliquely below the rectangular frame 923.

[0064] According to the above structure, the swing arm body 1 with the ball head assembly 2 installed will move to the lower part of the lateral pressing mechanism 9. Then the elevator platform two 901 operates and drives the semi-tube body 904 to move downward. When the semi-tube body 904 is supported by the semi-tube support 605, the semi-tube body 904 is just placed inside both ends of the swing arm body 1. Subsequently, the elevator platform two 901 continues to control the tapping block 903 to move downward. At this time, the through rod 905 will move relative to the semi-tube body 904 and simultaneously compress the first spring 906. At the same time, the two sides of the swing arms 910 push the two ends of the push rods 909 to move away from each other at the same time;

[0065] Under the elastic force of the second spring 919, the push rod 909 and the feeding part 911 will move together preferentially. When the clamping tube plate 912 sleeves the end of the swing arm body 1, the feeding part 911 is restricted and the push rod 909 will move relative to the feeding part 911, and the second spring 919 is compressed at the same time. Immediately afterwards, the push block 917 will penetrate into the bushing groove 913 and push out the swing arm bushing assembly 3 inside it. The swing arm bushing assemblies 3 at both ends will finally be pressed into both ends of the swing arm body 1;

[0066] When controlling the reset of the elevator platform two 901, both the push rod 909 and the feeding part 911 will be retracted into the interior of the end of the semi-tube body 904. Then, the semi-tube body 904 will move upward to reset. When it moves upward to the corresponding position, the inclined plate 916 will contact the bottom of the rectangular frame 923, and the rectangular frame 923 will then move. The upper baffle 924 will release the swing arm bushing assembly 3 at the bottommost position, and it will then roll into the corresponding bushing groove 913. The lower baffle 925 will enter the end of the discharge chute 922 and temporarily block the next swing arm bushing assembly 3, thus completing the replenishment work of the swing arm bushing assembly 3.

[0067] The above process provides a lateral pressing mechanism 9 that can press-fit two swing arm bushing assemblies 3 into both ends of the swing arm body 1 simultaneously. Cooperating with the pre-assembly mechanism 7 and the pressing mechanism 8, it jointly completes the assembly work of the ball joint control arm assembly. Moreover, this lateral pressing mechanism 9 can automatically complete the replenishment work of the swing arm bushing assembly 3 during the reset process of the semi-tube body 904, realizing the batch assembly work of the ball joint control arm assembly.

[0068] The working principle of the present invention is as follows: The swing arm body 1 with the ball head assembly 2 installed will move to the lower part of the lateral pressing mechanism 9. Then, the elevator platform two 901 will operate and carry the semi-tube body 904 downward. When the semi-tube body 904 is supported by the semi-tube support 605, the semi-tube body 904 is just placed inside both ends of the swing arm body 1. Subsequently, the elevator platform two 901 continues to control the sub-block 903 to move downward. At this time, the through rod 905 will move relative to the semi-tube body 904 and simultaneously compress the first spring 906. At the same time, the two side swing arms 910 will push the two end push rods 909 to move away from each other simultaneously. Under the elastic force of the second spring 919, the push rod 909 and the feeding part 911 will move together preferentially. When the clamping tube plate 912 sleeves the end of the swing arm body 1, the feeding part 911 is restricted and the push rod 909 will move relative to the feeding part 911, and the second spring 919 is compressed simultaneously. Immediately afterwards, the push block 917 will penetrate into the bushing groove 913 and push out the swing arm bushing assembly 3 inside it. The swing arm bushing assemblies 3 at both ends will finally be pressed into both ends of the swing arm body 1.

[0069] As Figure 14 shown, a modular assembly method for an automotive aluminum alloy ball joint control arm assembly is as follows:

[0070] S1: Assemble the ball head assembly 2, complete the production and assembly work of a single ball head assembly 2, and place each of them above the belt feeder 703 one by one.

[0071] S2: Pre-assemble the ball head assembly 2. Rotate the platform 601 to transport the swing arm body 1 to the pre-assembly mechanism 7 one by one, and use the pre-assembly mechanism 7 to pre-assemble the ball head assembly 2 into the corresponding hole positions of the swing arm body 1, and at the same time correct the angle of the ball pin 203.

[0072] S3: Press-fit the ball head assembly 2. Transport the swing arm body 1 carrying the ball head assembly 2 to the press-fitting mechanism 8 by rotating the platform 601, and use the press-fitting mechanism 8 to press-fit the ball head assembly 2 and the swing arm body 1;

[0073] S4: Press-fit the swing arm bushing assembly 3. Transport the swing arm body 1 with the ball head assembly 2 installed to the side press-fitting mechanism 9 by rotating the platform 601, and use the side press-fitting mechanism 9 to press-fit the swing arm bushing assembly 3 into both ends of the swing arm body 1 simultaneously.

[0074] The above are only the preferred embodiments of the present invention.
