Description

[0001] This application is a divisional application with application number 2024102530665, application date March 6, 2024, and invention name “A car lower arm ball head assembly platform”. Technical Field

[0002] The invention relates to the technical field of automobile parts assembly, in particular to an assembly platform. Background Art

[0003] The car lower arm, also known as the car lower suspension, is a part of the car's suspension system. Among them, a component connected to the car lower arm is the ball head. The two work together to stabilize the car body and assist steering.

[0004] After the vehicle has been used for a long time, the ball head of the lower control arm may wear out the spherical surface due to lack of lubricating oil, thereby producing a gap. In this case, the vehicle is prone to bumps when driving, causing the steering wheel to shake, which poses a very high safety hazard. The ball head needs to be removed from the lower control arm and replaced. When disassembling or assembling in the prior art, a sleeve with the same size as the outer diameter of the ball head is required to limit the movement direction of the ball head so that it moves vertically, and the sleeve is placed on one side of the lower control arm so that it is opposite to the ball head to avoid the ball head from shifting during disassembly or installation, resulting in operation failure. The ball head is squeezed into the sleeve through the screw structure, but the sleeve is generally provided with several fixed sizes. When looking for a size that matches the ball head, it needs to be adapted one by one, and in the most suitable size, there is still a certain gap with the size of the diameter of the ball head, which leads to assembly errors that are still easy to occur during disassembly or assembly, and the assembly effect is not good.

A driving motor 16 is provided on the output shaft of the driving motor 16. The driving shaft includes a driving screw 4 and a first shaft 41. The driving screw 4 is fixedly mounted on the output shaft of the driving motor 16. A movable slide groove is provided at the bottom of the driving screw 4. The first shaft 41 is inserted into the movable slide groove. A moving mechanism is provided on the assembly table 1. The driving motor 16 drives the driving shaft to rotate to move the moving mechanism downward. The ball head 15 is squeezed by the moving mechanism and the lower swing arm 12 is fixed at the same time. The ball head 15 is moved downward to make it contact with the limit rod and drive the limit rod to expand. Under the action of the slide rail 14, the limit rod moves in the synchronous groove 21, thereby rotating the rotating disk 2. At the same time, the movement trajectory of the ball head 15 is limited by the limit unit so that it moves perpendicular to the lower swing arm 12, thereby solving the problem of easy assembly failure caused by the deviation of the movement direction of the ball head 15 when assembling the ball head 15 in the prior art.

[0033] The moving mechanism includes a movable block 42, a linkage disk 5, a spring telescopic rod 51 and a pressure plate 52. The movable block 42 is threadedly connected to the driving screw 4. The linkage disk 5 is fixedly connected to the bottom of the movable block 42 through a connecting rod. The spring telescopic rod 51 is fixedly installed at the bottom of the movable block 42.

The rotating groove 54 passes through the lower surface of the linkage disk 5. A first through hole 55 is opened on the upper surface of the linkage disk 5. The first through hole 55 is connected to the rotating groove 54. The first shaft 41 passes through the first through hole 55 and is fixedly installed There is a first gear 56, and a second gear 6 is rotatably connected in the rotating groove 54. The first gear 56 is meshed with the second gear 6. A plurality of pressing mechanisms are arranged on the linkage disk 5. The driving motor 16 drives the driving screw rod 4 to rotate. Under the action of the second slide rod 62, the movable block 42 is vertically moved downward, and the first shaft rod 41 is synchronously moved downward by the movable block 42. At the same time, under the action of the driving screw rod 4, the first gear 56 drives the second gear 6 to rotate, so that the pressing mechanism produces a rotating pressing effect. At the same time, when the pressing plate 52 moves to the specified position, the pressing plate 52 contacts the lower swing arm 12, and the movable block 42 continues to move downward, so that the spring telescopic rod 51 is compressed, and the lower swing arm 12 is clamped and fixed.

[0034] The pressing mechanism is evenly distributed along the circumference of the second gear ring 92, and the pressing mechanism includes a linkage groove 61, a second slide bar 62, a slider 63 and a ball 64. The linkage groove 61 is opened on the upper surface of the second gear 6, and the bottom of the linkage groove 61 passes through the lower surface of the second gear ring 92. The second slide bar 62 is fixedly installed on the inner wall of the linkage groove 61, and the slider 63 is sleeved on the second slide bar 62. The bottom of the slider 63 extends out of the linkage groove 61, and the ball 64 is rotatably connected to the bottom of the slider 63. A linkage mechanism is provided on the assembly table 1. When the movable block 42 moves down a specified distance, the ball 64 contacts the upper surface of the ball head 15, and the ball 64 is driven to rotate by the second gear 6, so that the ball 64 rotates continuously while squeezing the ball head 15, so that the upper surface of the ball head 15 is evenly stressed, further avoiding the deflection of the ball head 15 during the assembly process, resulting in a non-vertical movement direction.

[0035] The linkage mechanism includes an arc-shaped rack 7, a second shaft 8, a first gear ring 81, a rotating screw 82 of a cylindrical structure, a synchronous rod 83, a rotating wheel 84, a first pressure block 85 and a second pressure block 58. The rack 7 is fixedly mounted on the upper surface of the rotating disk 2, the second shaft 8 is rotatably connected to the assembly table 1, a second through hole 57 is opened on the linkage disk 5, and the second shaft 8 passes through the second through hole 57. The first gear ring 81 is fixedly connected to the second shaft 8, the rotating screw 82 is rotatably connected to the upper surface of the linkage disk 5, the rotating screw 82 is connected to the sliding structure of the second shaft 8, the synchronous rod 83 is threadedly connected to the rotating screw 82, and the rotating wheel 84 is rotatably connected to the bottom of the synchronous rod 83. The first pressure block 85 is fixedly mounted on the rotating wheel 84 and is evenly distributed along the outer wall of the rotating wheel 84. The second pressure block 58 is fixed Installed on the top of the slider 63, the first pressure block 85 conflicts with the second pressure block 58. When the first ball head 15 is assembled, the limit rod moves to the specified position. At this time, the outer diameter formed by the plurality of limit rods is the same as the outer diameter of the ball head 15, which is convenient for the subsequent assembly to directly limit the ball head 15. At the same time, the rack 7 is driven to rotate by the rotating disk 2, and then the second shaft rod 8 is driven to rotate by the first gear ring 81, and the rotating screw 82 is driven to rotate by the second shaft rod 8, so that the synchronization rod 83 is pressed down, and the first pressure block 85 is pressed down by the synchronization rod 83. Under the action of the first pressure block 85 and the first pressure block 85, the second pressure block 58 drives the slider 63 to move on the slide rod. When the slider 63 moves, the rotation radius of the ball 64 increases, which further adapts to the size of the upper surface of the ball head 15 to make it more evenly stressed.

[0036] A guide rod 17 with an arc structure is fixedly installed on the assembly table 1, and a first spring 18 with an arc structure is arranged on the guide rod 17. A reset plate 27 is fixedly installed on the outer ring wall of the rotating disk 2. The reset plate 27 is sleeved on the guide rod 17. The reset plate 27 is in contact with the first spring 18. The reset plate 27 is squeezed by the first spring 18, so that the rotating disk 2 can be reset.

[0037] A second spring 65 is disposed on the second slide bar 62 , and the second spring 65 is used for resetting the slide block 63 .

[0038] A fixed seat 9 is fixedly installed on the assembly table 1, and a third shaft rod 91 is rotatably connected between the fixed seats 9. A second gear ring 92 is fixedly installed on the third shaft rod 91. A plurality of evenly distributed transmission teeth 59 are arranged on the outer ring wall of the rotating disk 2, and the second gear ring 92 is meshed and connected with the transmission teeth 59. A ratchet 93 is arranged on the shaft rod, and a spring pawl 94 is arranged on the fixed seat 9. The transmission teeth 59 are rotated by rotating the rotating disk 2, and then the second gear ring 92 drives the third shaft rod 91 to rotate. At this time, the ratchet 93 rotates, and under the action of the first spring 18, the ratchet 93 is made to resist the spring pawl 94, and the ratchet 93 is clamped by the spring pawl 94, so that the rotating disk 2 is clamped, and the limiting column 3 is fixed.

[0039] The top of the limiting column 3 is rotatably connected with a pulley 10 , which contacts with the ball head 15 . The pulley 10 is used to prevent the limiting column 3 from contacting with the ball head 15 and thus jamming the ball head 15 .

[0040] The specific working principle and method of use of the present invention are explained in detail below: Figure 1 This is the initial state of the assembly table 1. When in use, the lower swing arm 12 is placed on the storage table 11, and then the ball head 15 is placed on the lower swing arm 12. At this time, the ball head 15 contacts the pulley 10, and the driving motor 16 drives the driving shaft to rotate, so that the movable block 42 moves downward. At the same time, the first shaft drives the first gear 56 to rotate, and the second gear 6 drives the ball 64 to rotate. When the movable block 42 moves down to the specified position, the ball 64 contacts the upper surface of the ball head 15, and the ball head 15 is squeezed by the ball 64 to move it downward. At the same time, the upper surface of the ball head 15 is evenly stressed under the rotation of the ball 64. When the ball head 15 moves downward under the action of pressure, the outer wall of the ball head 15 contacts the pulley 10, and then the limit column 3 expands outward to cooperate with the ball 64 to avoid the problem of deflection of the ball head 15 during the downward movement, resulting in a non-vertical movement direction.

[0041] When the ball head 15 gradually moves downward, the rotating disk 2 is driven to rotate through the limiting column 3. At this time, the first gear ring 81 is driven to rotate through the rack 7, and then the second shaft drives the rotating screw 82 to rotate, and the synchronous rod 83 is pressed down by the rotating screw 82, so that the first pressure block 85 squeezes the second pressure block 58, so that the plurality of sliders 63 are moved away from each other. At this time, the rotation radius of the ball 64 is continuously increased, so that the extrusion force on the ball head 15 is more uniform. It should be noted that the first pressure block 85 and the second pressure block 58 are always in a state of conflict, and when the second gear 6 drives the ball 64 to rotate, the second pressure block 58 drives the rotating wheel 84 to rotate synchronously through the first pressure block 85. At the same time, the rotating disk 2 rotates, so that the transmission tooth 59 drives the second gear ring 92 to rotate, and the ratchet 93 is driven to rotate through the third shaft 91. When the first ball head 15 is assembled, the ratchet 93 is clamped by the spring ratchet to maintain the position of the limit rod, so that the limit rod can limit the ball head 15 of the same model during subsequent assembly.

[0042] When assembling ball heads 15 of different models, the ratchet 93 is released by moving the spring ratchet, and the rotating disk 2 is driven to rotate in the opposite direction under the action of the first spring 18, thereby resetting the limit unit. At the same time, the rotating screw 82 is rotated in the opposite direction by the reverse rotation of the second rack 7, and the synchronous rod 83 drives the first pressure block 85 to move upward, and the slider 63 drives the ball 64 to reset under the action of the second spring 65, so as to facilitate the assembly of ball heads 15 of different models and sizes.

[0043] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
