Description

Technical Field

[0001] The invention relates to the technical field of tie rod ball end assembly, in particular to an automobile tie rod ball end assembly system. Background Art

[0002] The tie rod ball joint is a key component in a vehicle's steering system. Located at each end of the steering rod, its primary function is to connect the rod to the knuckle arm or tie rod, enabling force transmission and motion conversion, ensuring accurate steering according to the driver's intent. Tie rod balls are typically made of high-strength alloy steel, offering excellent wear and fatigue resistance to withstand the complex conditions and loads of vehicle operation. Its internal structure, including the ball pin, ball seat, boot, and seals, features a precise fit that ensures steering flexibility and stability. Regular inspection and maintenance are required during daily use. Wear, looseness, or poor sealing can lead to unusual steering noises, deviations, and decreased handling, compromising driving safety. Prompt replacement is essential to ensure proper steering system operation and overall vehicle performance.

[0003] At present, when automobile tie rod ball heads are produced and assembled, an automobile tie rod ball head assembly assembly system is often set up to assemble its various accessories. However, when the ball pin head is assembled into the ball head seat, in order to prevent the ball pin head from detaching from the ball head seat, it is often necessary to add a riveting process to ensure that the opening of the ball head seat can be closed, so that the ball head seat can restrict the ball pin head. However, this operation has high requirements for riveting, and excessive riveting may occur, causing the ball head seat to bite the ball pin head and make it unable to move. Riveting may also cause the strength of the opening position of the ball head seat to deteriorate, and ultimately cause the riveted part of the opening of the ball head seat to be damaged after long-term use of the automobile tie rod ball head, causing the ball pin head to detach from the ball head seat. Therefore, the current automobile tie rod ball head assembly assembly system needs to solve the problem of excessive riveting or poor strength of the ball head seat caused by riveting the opening position of the ball head seat.

A heating pipe sleeve 38 is fixedly connected to the workbench 1 and is sleeved on the outside of the feed pipe 37. The heating pipe sleeve 38 is fixedly connected with an electric heating wire wrapped around the outside of the feed pipe 37.

[0040] The automobile tie rod ball head produced and processed by the present invention is as follows: Figures 6 to 8 As shown, it includes a ball head seat 42, a ball cover, a ball head 43, and a connecting column portion 44 integrally formed with the ball head 43. There is an active cavity in the ball head seat 42, and an opening communicating with the active cavity is opened on the top surface of the ball head seat 42. The ball cover is embedded in the active cavity, and the ball head 43 is embedded in the ball cover.

[0041] The ball head 43 and the connecting column 44 are composed of stainless steel sheets that are butt-welded at the edges. After the insert 45 is embedded in one end of the connecting column 44 of the butt-welded stainless steel sheet, the inner circle of the connecting column 44 tightly wraps the outer circle of the insert 45, and the upper end of the insert 45 is fixedly connected with a pin 46. After installing the insert 45 and the pin 46, the internal thread of the inner circle of the connecting sleeve 25 of the artificial inflation component is threadedly connected with the external thread of the outer circle of the pin 46, so that the inflation pump 19 can pass air through the inlet hole 47 opened in the pin 46 and the insert 45 for ventilation and pressurization, and finally the connecting column 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, the connecting column 44 forms a cylindrical structure, and the inner connecting bevel 50 of the inner circle of the connecting column 44 can be connected with The outer connecting inclined surfaces 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 column 44. There is a receiving groove 53 in the ball head 43. The end of the insert 45 away from the pin part 46 is fixedly connected to the tubular insert column 51 which is connected to the inlet hole 47. The outer ring of the insert column 51 is provided with a number of vertical through grooves 52 connecting the inner ring of the insert column 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 position of the inlet hole 47. The molten POM is then solidified. Since the temperature of the molten POM is within 200°C, it is injected into the stainless steel ball pin without affecting it. It can also connect the various structures of the ball pin, so that it has good integrity.

[0042] Moreover, this structure is used to complete the assembly and production of the automobile tie rod ball head, avoiding the riveting and sealing of the outer ring of the opening position of the ball head seat 42, and avoiding the structural strength of the ball head seat 42 at this location from declining. In this way, it is also avoided that the ball head pin destroys the opening position of the ball head seat 42 from the ball head seat 42 and then detaches. In addition, the automobile tie rod ball head formed by this structure itself is lighter in texture, but can still maintain good structural strength. When metal products are replaced by polymer compounds, the manufacturing cost of the automobile tie rod ball head can be further reduced.

[0043] During the process of assembling the automobile tie rod ball head through the automobile tie rod ball head assembly system, the ball head seat 42 is clamped by the robot arm 8 and placed on the placement tray 5. When the ball head seat 42 is placed on the placement tray 5 of the first workstation, the distance sensor 41 will detect the distance between it and the ball head seat 42 through the through hole. When ensuring that the ball head seat 42 is placed with its opening facing upward, the robot arm 8 releases the clamping of the ball head 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, so that the time relay is turned on and the power supply is supplied to the electromagnet 7, thereby generating magnetic force at the location of the placement tray 5, and then adsorbing the ball head seat 42 to prevent the ball head seat 42 from falling during the rotation of the turntable 3.

[0044] Driven by the rotating table 3, the ball head seat 42 is driven to the third work station. During this process, the vibrating plate 18 works, so that the vibrating plate 18 guides the ball cover therein to be displaced. The front electric slide 10 drives the front cylinder 11 to move to the discharge end of the vibrating plate 18, and then the front cylinder 11 drives the front pneumatic finger 111 to move downward and clamp the ball cover, thereby clamping the ball cover, and then the front cylinder 11 moves in the opposite direction, and the front electric slide 10 also moves in the opposite direction, and then drives the front cylinder 11, the front pneumatic finger 111 and the ball cover to move above the adapter slot 17 of the adapter plate 16, and then the front cylinder 11 drives the front pneumatic finger 111 to move downward, and the front pneumatic finger 111 is loosened. The ball cover is opened so that it can fall into the adapter slot 17, and the drive motor drives the adapter plate 16 to rotate 180 degrees, and then the rear cylinder 14 drives the rear pneumatic finger 141 to move downward, and the rear pneumatic finger 141 clamps the ball cover, and then the rear cylinder 14 drives the rear pneumatic finger 141 and the ball cover to move upward, and the rear electric slide 13 drives the rear cylinder 14, the rear pneumatic finger 141, and the ball cover to move, so that the ball cover can go above the opening of the ball head seat 42, and the rear cylinder 14 drives the rear pneumatic finger 141 and the ball cover to move downward, so that the ball cover can 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 13 return to their original positions.

[0045] Afterwards, the ball head seat 42 follows the rotating table 3 to the fourth workstation, and the operator manually places the uninflated ball head 43 and connecting column 44 in the ball cover, and inserts the plug 51 and the plug 45 into the connecting column 44, so that the outer ring of the plug 45 and the inner ring of the connecting column 44 fit together and seal. Then the operator threadedly connects the internal thread of the inner ring of the connecting sleeve 25 with the external thread of the outer ring of the pin 46, and the air pump 19 starts to work, so that pressurized air can be inflated through the inflatable metal bellows 23, so that the ball head 43 can be inflated to form a spherical head structure, and the connecting column 44 forms a cylindrical structure. After that, after turning off the air pump 19 again, the connecting sleeve 25 is manually disconnected from the pin 46, and re-inserted into the groove through the chuck 24.

[0046] Then the rotating table 3 drives the ball seat to the bottom of the active injection molding component, and then the horizontal electric slide 27, the longitudinal electric slide 28, and the vertical electric slide 30 are used to adjust the position of the adjustment cylinder 31 and the guide plate 34. When the guide plate 34 moves downward, the guide arc groove 35 can guide the ball pin so that the ball pin can pass through the guide hole, and the opening of the inlet hole 47 on the ball pin is coaxially aligned with the injection head 33. Then the adjustment cylinder 31 drives the connecting seat 32 and the injection head 33 to move downward, so that the injection head The top surface of the pin portion 46 of 33 is in conflict, and the interior of the injection head 33 is coaxially connected with the inlet hole 47 on the pin portion 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 pin. In this process, the heating pipe sleeve 38 can keep the feed pipe 37 warm. At the same time, the heating wire in the heating pipe sleeve 38 can also ensure that the feed pipe 37 can still maintain a certain temperature to prevent the molten POM from solidifying in the feed pipe 37 and the molten metal bellows 39.

[0047] After the ball pin of the molten POM is injected and follows the ball seat 42 to continue to move with the turntable 3 through the sixth to eighth stations, the fan 40 is used to cool the ball pin to make the molten POM solidify as soon as possible, so that the ball pin can form a complete and integrated structure. At the eighth station, the time relay timing ends and disconnects the path between the power supply and the electromagnet 7. After the electromagnet 7 is powered off, the electromagnet 7 no longer attracts the ball seat 42, so that the automobile tie rod ball head can be unloaded.

[0048] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
