A through hole 710 is penetrated at the center of the clamping platform 709, and a half-groove block 711 is symmetrically slidably assembled inside the through hole 710, and the surfaces of the two half-groove blocks 711 are provided with half-grooves 712 for the ball head assembly 2 to fall into, double-threaded screws 713 are rotatably installed on both sides of the inside of the clamping platform 709, and the side walls of the half-groove blocks 711 are fixedly provided with spiral tubes sleeved on the outer surface of the double-threaded screws 713, and a power shell 714 is fixedly provided on one side of the outer wall of the clamping platform 709, and a double-axis motor for driving the two double-threaded screws 713 to rotate is assembled inside the power shell 714; See attached Figure 5-Figure 8 The telescopic output end of the lifting platform 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 ring array. The bottom of the clamping rod 715 is movably assembled with a clamping block 719 in a ring array, and the clamping block 719 is used to clamp the ball pin 203 when it is aggregated. The outer wall of the clamping block 719 is integrally provided with a wedge block 720, and the wedge block 720 is slidably assembled in the corresponding inclined groove rail 716. 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 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.

[0026] 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; Subsequently, the lifting platform 1 702 controls the clamping rod 715 to move downward. When the bottom end of the clamping rod 715 is close to the ball pin 203, the cylinder 2 717 extends and operates, and each clamping block 719 is pushed and moves together along the inclined groove rail 716. When the clamping blocks 719 gather together, they clamp the ball pin 203 together. In this process, since the half trough 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, and at the same time facilitate the subsequent press-fitting work; Finally, the dual-axis motor in the power housing 714 starts and drives the two double-threaded 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; 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 rotating platform 601. The ball head assembly 2 can be pre-installed into the hole position of the swing arm body 1 one by one through the pre-installation mechanism 7, and the ball pin 203 is corrected during the pre-installation process to ensure that the ball pin 203 is perpendicular to the ball shell 201, which is beneficial to the subsequent press-fitting work of the ball head assembly 2 by the press-fitting mechanism 8.

[0027] 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, 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 located 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; then, the lifting platform 1 702 controls the clamping rod 715 to move downward, and 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 moved along the inclined groove rail 71 6 gather and move, and each clamping block 719 will clamp the ball pin 203 together when it gathers. During the process, since the half-groove 712 limits 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, which is convenient for subsequent press-fitting work; finally, the double-axis motor in the power shell 714 starts and drives the two double-threaded screws 713 to rotate at the same time. At this time, the two half-groove blocks 711 will move away from each other, and then the clamping rod 715 will continue to move downward through the lifting platform 702. The clamping rod 715 will carry the ball head assembly 2 through the clamping platform 709 and finally send it into the corresponding hole position of the swing arm body 1.

[0028] Embodiment 2: See attached Figure 10-13 , a lifting platform 901 is fixedly provided on the top of the lateral pressing mechanism 9, a working rod 902 is integrally provided at the telescopic output end of the lifting platform 901, and a tapping block 903 is integrally provided at the end of the working rod 902, a semi-tube 904 is movably assembled on the inner side of the lateral pressing mechanism 9 and located at the bottom of the lifting platform 901, a through rod 905 is fixedly connected to the bottom of the tapping block 903, the through rod 905 slidably penetrates the middle of the semi-tube 904 and a spring 906 is sleeved on its outer surface, both side walls of the middle of the semi-tube 904 are integrally provided with straight groove plates 907, and both sides of the tapping block 903 are integrally provided with guide blocks 908 that movably penetrate the straight groove plates 907; See attached Figure 10-13, both ends of the half-tube body 904 are movably assembled with a push rod 909 and a feeding piece 911, and the push rod 909 is placed on the inner side of the feeding piece 911, and the two ends of the tapping block 903 are connected to one end of the corresponding push rod 909 through a rotating arm 910, and the edge of the feeding piece 911 away from the push rod 909 is integrally provided with a clamping plate 912 for covering the end of the swing arm body 1, and the inner part of the feeding piece 911 near the clamping plate 912 is provided with a bushing groove 913 for placing the swing arm bushing assembly 3, and the feeding piece The outer wall of the part of 911 containing the bushing groove 913 is integrally provided with an inclined plate 916, the middle part of the feeding piece 911 is integrally provided with a partition plate 914, the outer wall of the feeding piece 911 close to the tube clamping plate 912 is fixedly provided with a guide tube 915, the push rod 909 penetrates the partition plate 914 and extends to the end of the bushing groove 913, and a push block 917 is fixedly provided, and the outer walls on both sides of the push block 917 are fixedly connected with guide pillars 918, and the guide pillars 918 penetrate the corresponding guide pillars 918 and the outer surface is sleeved with a spring 2 919; See attached Figure 10-13 The lateral pressing mechanism 9 is located on the side wall of the bottom of the lifting platform 901, and a feeding rack 920 is fixedly installed. Both ends of the inner side of the feeding rack 920 are integrally provided with a collection shell 921 for collecting the swing arm bushing assembly 3, and the bottom end of the collection shell 921 is integrally provided with a discharge trough 922, and the end of the discharge trough 922 is elastically slidably assembled with a rectangular frame 923, and an upper baffle 924 is integrally provided at the oblique upper part of the rectangular frame 923, and a lower baffle 925 is integrally provided at the oblique lower part of the rectangular frame 923.

[0029] According to the above structure, the swing arm body 1 after the ball head assembly 2 is installed will move to the bottom of the lateral pressing mechanism 9, and the second lifting platform 901 will then operate and carry the half-tube body 904 downward. When the half-tube body 904 is supported by the half-tube support seat 605, the half-tube body 904 is just placed on the inner side of the two ends of the swing arm body 1. Then the second lifting platform 901 continues to control the tapping block 903 to move downward. At this time, the through rod 905 will move relative to the half-tube body 904 and compress the spring 1 906 at the same time. At the same time, the push rods 909 at both ends are pushed to move backwards at the same time through the rotating arms 910 on both sides. Under the elastic force of the second spring 919, the push rod 909 and the feed piece 911 will move together first. When the clamping plate 912 covers the end of the swing arm body 1, the feed piece 911 is restricted and the push rod 909 and the feed piece 911 will move relative to each other. The second spring 919 is compressed at the same time. Then, the push block 917 will go deep 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 eventually be pressed into the two ends of the swing arm body 1. When the second lifting platform 901 is controlled to reset, the push rod 909 and the feeding piece 911 will be recovered to the inside of the end of the half-tube body 904, and the half-tube body 904 will then move upward to reset. When it moves upward to the corresponding position, the inclined plate 916 will come into contact with 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 bottom, and it will then roll into the corresponding bushing groove 913, and the lower baffle 925 will enter the end of the discharge groove 922 and temporarily block the next swing arm bushing assembly 3, thereby completing the replenishment of the swing arm bushing assembly 3; The above process provides a lateral pressing mechanism 9 that can simultaneously press-fit two swing arm bushing assemblies 3 into the two ends of the swing arm body 1, and cooperates with the pre-installation mechanism 7 and the pressing mechanism 8 to jointly complete the assembly of the ball joint control arm assembly. In addition, the lateral pressing mechanism 9 can automatically complete the replenishment of the swing arm bushing assembly 3 during the resetting process of the semi-tube body 904, thereby realizing the batch assembly of the ball joint control arm assembly.

[0030] The working principle of the present invention is as follows: the swing arm body 1 after the ball head assembly 2 is installed will move to the bottom of the lateral pressing mechanism 9, and the second lifting platform 901 will then operate and carry the half-tube body 904 downward. When the half-tube body 904 is supported by the half-tube support seat 605, the half-tube body 904 is just placed on the inner side of the two ends of the swing arm body 1. Then the second lifting platform 901 continues to control the tapping block 903 to move downward. At this time, the through rod 905 will move relative to the half-tube body 904 and compress the spring 1 906 at the same time.
