Description

Technical Field

[0001] This invention relates to the field of tie rod ball joint assembly technology, and more particularly to an automotive tie rod ball joint assembly system. Background Technology

[0002] The tie rod ball joint is a key component of a car's steering system. Located at both ends of the steering tie rod, its main function is to connect the tie rod to the steering knuckle arm or steering tie rod, enabling the transmission of force and the conversion of motion, ensuring that the wheels can be steered accurately according to the driver's intentions. Tie rod ball joints are typically made of high-strength alloy steel, possessing excellent wear resistance and fatigue resistance to withstand various complex conditions and loads during vehicle operation. Its internal structure includes the ball joint head, ball joint seat, dust cover, and seals, with precise fit ensuring steering flexibility and stability. In daily use, tie rod ball joints require regular inspection and maintenance. Wear, loosening, or poor sealing can lead to problems such as abnormal steering noise, vehicle drift, and decreased handling performance, affecting driving safety. Timely replacement is necessary to ensure the normal operation of the car's steering system and the overall performance of the vehicle.

[0003] Currently, in the production and assembly of automotive tie rod ball joints, an automotive tie rod ball joint assembly system is often set up to assemble its various components. However, when assembling the ball pin into the ball joint seat, in order to prevent the ball pin from detaching from the ball joint seat, a riveting process is often added to ensure that the opening of the ball joint seat can be closed, thereby restricting the ball pin. However, this operation has high requirements for riveting, and over-riveting may occur, causing the ball joint seat to lock the ball pin and prevent it from moving. Alternatively, riveting may weaken the strength of the opening of the ball joint seat, ultimately leading to damage at the riveted area of ​​the ball joint seat opening after long-term use, causing the ball pin to detach from the ball joint seat. Therefore, it is necessary to solve the problem of over-riveting or weakening of the ball joint seat due to riveting at the opening of the current automotive tie rod ball joint assembly system.

[0039] The active injection molding assembly includes an injection molding machine 36 mounted on one side of the worktable 1, a support frame 26 fixedly connected to the worktable 1, a horizontal electric slide rail 27 fixedly connected to the support frame 26, a vertical electric slide rail 28 fixedly connected to the slide base of the horizontal electric slide rail 27, a vertical electric slide rail 30 fixedly connected to the slide base of the vertical electric slide rail 28 via a mounting base 29, a guide plate 34 fixedly connected to the slide base of the vertical electric slide rail 30, and a connecting seat 32 located above the guide plate 34. The guide plate 34 has a guide hole and an upwardly recessed part on its bottom surface. A guide arc groove 35 is recessed and coaxially connected to the guide hole. A vertically arranged adjusting cylinder 31 is fixedly connected to the slide of the vertical electric slide rail 30. A connecting seat 32 is fixedly connected to the movable end of the adjusting cylinder 31. An injection head 33 is fixedly connected inside the connecting seat 32 and passes through it and is coaxially arranged with the guide hole. The injection head 33 is connected to the output end of the injection molding machine 36 through the molten metal bellows 39 and the feed pipe 37 in sequence. A heating tube sleeve 38 is fixedly connected to the worktable 1 and sleeved on the outside of the feed pipe 37. An electric heating wire is fixedly connected inside the heating tube sleeve 38 and wound around the outside of the feed pipe 37.

[0040] The automotive tie rod ball joint produced and processed by this invention, such as... Figures 6 to 8 As shown, it includes a ball head seat 42, a ball cover, a ball head 43, and a connecting column 44 integrally formed with the ball head 43. The ball head seat 42 has a movable cavity, and the top surface of the ball head seat 42 has an opening communicating with the movable cavity. The ball cover is embedded in the movable cavity, and the ball head 43 is embedded in the ball cover.

[0041] The ball head 43 and the connecting post 44 are composed of stainless steel sheets welded to their edges. After the insert 45 is embedded in one end of the connecting post 44, the inner ring of the connecting post 44 tightly wraps the outer ring of the insert 45. The upper end of the insert 45 is fixedly connected to a pin 46. After installing the insert 45 and the pin 46, the inner thread of the inner ring of the connecting sleeve 25 of the artificial air-blowing assembly is threaded to the outer thread of the outer ring of the pin 46, so that the air pump 19 can pressurize the air by passing air through the inlet holes 47 opened in the pin 46 and the insert 45. Finally, the connecting post 44 and the ball head 43 can be inflated and pressurized. Under the influence of the air pressure forming process, the ball head 43 forms a spherical structure, and the connecting post 44 forms a cylindrical structure. The inner connecting slope 50 of the inner ring of the connecting post 44 can connect with the inner thread of the connecting post 44. The outer connecting bevels 48 of the outer ring of the insert 45 fit together, and there is an inlet groove 49 between the outer ring of the insert 45 and the inner ring of the connecting post 44. There is a receiving groove 53 in the ball head 43. The end of the insert 45 away from the pin 46 is fixedly connected to a tubular insert post 51 that communicates with the inlet hole 47. The outer ring of the insert post 51 has several vertical through grooves 52 that communicate with the inner ring of the insert post 51 and the receiving groove 53. The subsequent injection assembly injects molten POM through the inlet hole 47 toward the receiving groove 53, the inlet groove 49, and the vertical through groove 52 until the molten POM overflows from the opening of the inlet hole 47. Then, the molten POM is allowed to solidify. Since the temperature of the molten POM is below 200℃, it will not affect the stainless steel ball head pin when injected into it. It can also connect the various structures of the ball head pin, giving it good integrity.

[0042] Furthermore, this structure enables the assembly and production of automotive tie rod ball joints, avoiding the need for riveting and sealing the outer ring of the ball joint seat 42 opening. This prevents a decline in the structural strength of the ball joint seat 42 at that location. Consequently, it also prevents the ball pin from breaking through the opening of the ball joint seat 42 and detaching. Moreover, the automotive tie rod ball joint formed by this structure is lightweight yet maintains good structural strength. By replacing metal products with polymer compounds, the manufacturing cost of automotive tie rod ball joints can be further reduced.

[0043] During the assembly of the automotive tie rod ball joint assembly using this automotive tie rod ball joint assembly system, the robotic arm 8 clamps the ball joint seat 42 and places it on the placement tray 5. When the ball joint seat 42 is placed on the placement tray 5 of the first station, the distance sensor 41 detects the distance between itself and the ball joint seat 42 through the through hole. When the ball joint seat 42 is placed with its opening facing upwards, the robotic arm 8 releases its grip on the ball joint seat 42 and controls the wireless transmitter to transmit a wireless signal to the wireless receiver through the controller. The wireless receiver receives the signal and sends a signal to the time relay, causing the time relay to conduct and powering the electromagnet 7. This generates a magnetic force at the location of the placement tray 5, which then attracts the ball joint seat 42, preventing the ball joint seat 42 from falling off during the rotation of the turntable 3.

[0044] Driven by the rotating table 3, the ball head seat 42 is moved to the third station. During this process, the vibratory plate 18 works, allowing the ball cover within it to move. The front electric slide rail 10 drives the front cylinder 11 to move to the discharge end of the vibratory plate 18. Then, the front cylinder 11 drives the front pneumatic finger 111 to move downward and clamp the ball cover, thus holding the ball cover. Then, the front cylinder 11 moves in the opposite direction, and the front electric slide rail 10 also moves in the opposite direction, thereby moving the front cylinder 11, the front pneumatic finger 111, and the ball cover to the top of the transfer groove 17 of the transfer plate 16. Then, the front cylinder 11 drives the front pneumatic finger 111 to move downward, and the front pneumatic finger 111 releases... The ball cover is opened, allowing it to fall into the adapter slot 17. The drive motor drives the adapter plate 16 to rotate 180°. Then, the rear cylinder 14 drives the rear pneumatic finger 141 to move downward, clamping the ball cover. Afterward, the rear cylinder 14 drives the rear pneumatic finger 141 and the ball cover to move upward. The rear electric slide rail 13 drives the rear cylinder 14, the rear pneumatic finger 141, and the ball cover to move, allowing the ball cover to reach above the opening of the ball head seat 42. The rear cylinder 14 drives the rear pneumatic finger 141 and the ball cover to move downward, allowing the ball cover to be embedded in the ball head seat 42. After the rear pneumatic finger 141 releases the ball cover, the rear cylinder 14 and the rear electric slide rail 13 return to their original positions.

[0045] Then, the ball head seat 42 follows the rotating table 3 to the fourth station. The operator manually places the uninflated ball head 43 and connecting column 44 inside the ball cover, and inserts the insert 51 and insert 45 into the connecting column 44, so that the outer ring of the insert 45 and the inner ring of the connecting column 44 fit together and seal. Then, the operator threadedly connects the inner thread of the inner ring of the connecting sleeve 25 with the outer thread of the outer ring of the pin 46. The air pump 19 starts to work, so that pressurized air can be inflated through the air-inflating metal bellows 23, so that the ball head 43 can be inflated to form a ball head structure and the connecting column 44 can form a cylindrical structure. After that, the air pump 19 is turned off again, and the connecting sleeve 25 and the pin 46 are disconnected manually and re-clamped into the groove through the chuck 24.

[0046] Then, the rotating table 3 moves the ball seat below the active injection assembly. The horizontal electric slide rail 27, vertical electric slide rail 28, and vertical electric slide rail 30 then adjust the position of the adjusting cylinder 31 and the guide plate 34. When the guide plate 34 moves downward, the guide groove 35 guides the ball pin, allowing it to pass through the guide hole and aligning the inlet hole 47 on the ball pin with the injection head 33 coaxially. Then, the adjusting cylinder 31 moves the connecting seat 32 and the injection head 33 downward, allowing the injection head... The top surface of the pin 46 abuts against the injection head 33, making the inside of the injection head 33 coaxially connected with the inlet hole 47 on the pin 46. Then, the injection molding machine 36 guides the molten POM through the feed pipe 37 and the molten metal bellows 39, and the injection head 33 into the ball head pin. During this process, the heating sleeve 38 can keep the feed pipe 37 warm, and the heating wire inside the heating sleeve 38 can also ensure that the feed pipe 37 can still maintain a certain temperature, preventing the molten POM from solidifying in the feed pipe 37 and the molten metal bellows 39.

[0047] After the ball head pin, which has been injection-molded with molten POM, continues to move along with the ball head seat 42 and the rotating table 3 through the sixth to eighth stations, the fan 40 cools the ball head pin, so that the molten POM solidifies as soon as possible, thereby enabling the ball head pin to form a complete and integrated structure. At the eighth station, the time relay ends and disconnects the power supply from the electromagnet 7. After the electromagnet 7 is de-energized, it no longer attracts the ball head seat 42, so that the ball head of the automotive tie rod can be unloaded.

[0048] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
