Description

Technical Field

[0001] This invention relates to the field of automotive parts assembly technology, and specifically discloses an automotive chassis steering knuckle assembly platform. Background Technology

[0002] With the development of automotive technology and the continuous maturation of automation technology, my country's industrial automation technology has been rapidly promoted. On the production line, more and more jobs are being replaced by automated assembly lines, and the automated assembly industry of construction machinery is constantly improving.

[0003] For example, the invention patent with patent number 2018115964968 discloses an automatic assembly machine and assembly method for automobile wheel hub steering knuckles. It includes a steering knuckle feeding conveyor line, which is connected to a pressing device I via a steering knuckle feeding robot. The pressing device I is connected to a bearing hopper with a conveying mechanism via a bearing feeding robot. The pressing device I completes the pressing and testing of steering knuckles, bearings, and snap rings. The pressing device I is connected to a pressing device II via a conveying robot. The pressing device II is connected to a wheel hub hopper with a conveying and stopping mechanism via a wheel hub feeding robot. The pressing device II completes the pressing of the wheel hub, the detection of wheel hub end face runout of the steering knuckle assembly, and the marking of the steering knuckle assembly. The pressing device II is connected to a finished product disassembly device via an unloading robot.

[0004] When installing a car steering knuckle, the bearing is first installed inside the steering knuckle, and then the wheel hub is pressed into the bearing to complete the installation. Existing car steering knuckle mounting platforms simply use a robotic arm to move the bearing and wheel hub to the designated position and then install the bearing and wheel hub sequentially. Because the steering knuckle needs to be pressed in twice, the assembly time is extended, thus reducing the efficiency of steering knuckle assembly. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide an automotive chassis steering knuckle assembly platform to solve the problem that existing automotive steering knuckle mounting platforms require a robotic arm to move the bearing and wheel hub to a designated position during steering knuckle installation, and then install the bearing and wheel hub sequentially, which requires two press-fitting operations on the steering knuckle, thereby reducing the efficiency of steering knuckle installation.

[0006] Technical issues.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a steering knuckle assembly platform for an automobile chassis, comprising a first fixed platform, a support base and a second fixed platform fixedly connected to the first fixed platform, a moving mechanism provided on the second fixed platform, the moving mechanism comprising a first rotating device fixedly connected to the second fixed platform, a mating block provided at the output end of the first rotating device, three sets of fixing components for fixing the steering knuckle provided on the mating block, each of the three sets of fixing components being fixedly connected to the steering knuckle; three sets of feeding and conveying devices provided on the first fixed platform, the three sets of fixing components respectively located above the three sets of feeding and conveying devices; a moving device for transporting bearings is provided above one set of feeding and conveying devices, an installation mechanism for installing the bearing and wheel hub into the steering knuckle is provided between the bearing and the corresponding feeding and conveying device, the moving device being located above the installation mechanism. By moving the steering knuckle through the moving mechanism, it is possible to clamp the new steering knuckle during installation and simultaneously release the already installed steering knuckle, thus making reasonable use of time and improving the efficiency of steering knuckle assembly.

[0008] Furthermore, the installation mechanism includes a second fixed frame, which is fixedly connected to a first fixed platform. A first fixed block is mounted on the second fixed frame, and a second rotating device is mounted on the first fixed block. A rotating block is fixedly connected to the output end of the second rotating device. Three sets of tensioning components are mounted on the rotating block, and the bearing is fitted onto these three sets of tensioning components. A telescopic hydraulic cylinder is mounted on the rotating block, and a push block is fixedly connected to the telescopic end of the cylinder. The push block contacts the bearing and is located below the bearing. This installation mechanism is used to install the bearing and wheel hub onto the steering knuckle. Simultaneously, the telescopic hydraulic cylinder completes the installation of the bearing and wheel hub with only one extension and retraction, thereby improving the efficiency of steering knuckle assembly.

[0009] Furthermore, the second fixed frame is provided with a support mechanism, which includes a movable rod. The steering knuckle has a second mounting hole, and the movable rod passes through the second mounting hole. A slider is slidably mounted on the second fixed frame, and the movable rod passes through the slider. A first connecting rod is fitted onto the movable rod, and a support platform is fixedly connected to the first connecting rod. A hydraulic cylinder is fixedly connected to the support platform, and the telescopic end of the hydraulic cylinder is fixedly connected to the movable rod. The support mechanism is used to cooperate with the fixed assembly to fix both ends of the steering knuckle, thereby ensuring that the steering knuckle remains level when the bearing and wheel hub are installed into the steering knuckle.

[0010] Furthermore, a fixing hole is provided on the first fixing platform, and a mating mechanism is provided below the fixing hole. The mating mechanism includes a connecting ring, on which a first connecting rod and a third connecting rod are fixedly connected. The third connecting rod is slidably engaged within the first fixing platform. A bracket is provided on the third connecting rod, and the slider is located below the fixing assembly, contacting the fixing assembly. The mating mechanism is used to lift the support mechanism and the fixing assembly, thereby ensuring that the steering knuckle can be raised and lowered smoothly, thus completing the assembly of the steering knuckle.

[0011] Furthermore, two sets of mating posts are fixedly connected below the connecting ring, and the two sets of mating posts are respectively installed inside the two sets of cylinders; hydraulic oil is provided between the mating posts and the cylinders, and a pressure valve is provided at one end of the cylinder, with a hydraulic oil pipe connected to the pressure valve, and the hydraulic oil pipe is connected to the hydraulic oil station. The mating posts cooperate with the cylinders, ensuring that the hydraulic oil in the cylinders will only flow out of the cylinders through the pressure valve when subjected to a certain pressure.

[0012] Furthermore, the fixing assembly includes a first connecting block fixedly connected to the mating block. A second connecting block, movable vertically, is mounted on the first connecting block. A double-headed hydraulic cylinder is fixedly connected to the second connecting block. Each of the two telescopic ends of the double-headed hydraulic cylinder is provided with a first connecting frame and a second connecting frame. Each of the two sets of second connecting frames is provided with two sets of fixing posts. The steering knuckle is provided with two sets of first mounting holes. The two sets of second connecting frames are respectively located at both ends of the first mounting holes. The two sets of fixing posts on the second connecting frames are respectively inserted into the two sets of first mounting holes. The fixing assembly is used to fix the steering knuckle, thereby allowing the steering knuckle to move.

[0013] Furthermore, the tensioning assembly includes a second fixing block, which is fixedly connected to the rotating block. The second fixing block has two sets of clamping blocks, and several sets of rotatable rubber wheels are positioned between the two sets of clamping blocks. These rubber wheels are in close contact with the inner wall of the bearing. The tensioning assembly secures the bearing through the rubber wheels, and prevents scratching the bearing when it is removed from the tensioning assembly, thus ensuring the integrity of the bearing.

[0014] Furthermore, a guiding mechanism is provided on the first fixed platform. The guiding mechanism is located above one of the sets of feeding and conveying devices. The guiding mechanism includes two sets of first guiding blocks, both of which are fixedly connected to the first fixed platform. Two sets of first fixing frames and two sets of second guiding blocks are fixedly connected to the first fixed platform. The two sets of first guiding blocks and the two sets of second guiding blocks are arranged in a V-shape. The guiding mechanism is used to guide the position of the steering knuckle, facilitating the fixing assembly to fix the steering knuckle.

[0015] Furthermore, a first fixing groove and a second fixing groove are provided on the first fixing platform, both of which are arc-shaped; the steering knuckle can move within the first fixing groove, and the wheel hub can move within the second fixing groove.

[0016] Furthermore, two sets of third fixing blocks are fixedly connected below the first fixing platform, and an arc-shaped frame is fixedly connected between the two sets of third fixing blocks. The arc-shaped frame is located above one of the feeding and conveying devices.

[0017] The working principle and beneficial effects of this solution are as follows:

[0018] Workers move the steering knuckle to the designated position using the loading and conveying device, then control the fixing component to secure the steering knuckle. Next, the first rotating device is activated, moving the fixing component and steering knuckle between the bearing and the wheel hub. Then, the support mechanism is activated to fix the steering knuckle in place. At this point, the support mechanism and fixing component secure both ends of the steering knuckle, ensuring it does not shift. The first rotating device is then activated again, placing the assembled steering knuckle, bearing, and wheel hub onto the corresponding loading and conveying device and moving them to the designated position. This allows for rapid installation of the steering knuckle, bearing, and wheel hub. During processing, only one step is needed to complete the installation of the steering knuckle, bearing, and wheel hub, thus improving installation efficiency.

[0019] When installing the steering knuckle, bearing, and wheel hub, the operator first activates the second rotating device to rotate the bearing 180 degrees. Then, the telescopic hydraulic cylinder is activated, and the bearing is moved downwards by the pusher block, allowing it to be inserted into the steering knuckle until it is completely pressed into the steering knuckle. The telescopic hydraulic cylinder then extends further, and pressure is applied to it, causing the steering knuckle to descend and allowing the wheel hub to be inserted into the bearing. This completes the installation of the steering knuckle, bearing, and wheel hub. The installation of the steering knuckle, bearing, and wheel hub can be completed with only one extension of the telescopic hydraulic cylinder, saving installation time and improving installation efficiency.

[0040] The second fixed frame 401 is provided with a support mechanism for auxiliary support of the steering knuckle 104. The support mechanism includes a movable rod 503.

[0041] A fixing hole 112 is provided on the first fixed platform 101. A set of steering knuckles 104 is located above the fixing hole 112. A mating mechanism is provided below the fixing hole 112. The mating mechanism includes a connecting ring 507, which is circular and aligned with the fixing hole 112. The connecting ring 507 is fixedly connected to the first connecting rod 506.

[0043] The moving device, the feeding and conveying device 102, the first rotating device 201, the double-headed hydraulic cylinder 207, the second rotating device 403, and the telescopic hydraulic cylinder 408 are all technical means commonly used by those skilled in the art, and their structures, connection methods, and usage methods are well known to those skilled in the art.

[0044] When the cylinder body 511 is engaged with the mating column 512, it is in a sealed engagement, similar to the principle of a hydraulic cylinder. The hydraulic oil station is a commonly used technical means in the field of hydraulics. By engaging the hydraulic oil station, hydraulic oil pipe 514, pressure valve 513, mating column 512 and cylinder body 511, the operating state of the hydraulic cylinder 504 can be simulated.

[0045] In practice:

[0046] In use, the operator first activates the loading and conveying device 102. Through the two sets of loading and conveying devices 102 and the moving device, the corresponding steering knuckle 104, bearing 105, and wheel hub 106 are moved to their designated positions. When the steering knuckle 104 is moved by the loading and conveying device 102, it first cooperates with two sets of first guide blocks 301 to ensure that it is moved to a position aligned with the corresponding fixed component. Then, through two sets of second guide blocks 303, the state of the steering knuckle 104 is adjusted, allowing it to move to the designated position. After placement, the fixing post 210 can be aligned with the first mounting hole 108. When the steering knuckle 104 moves to the designated position, the feeding transmission device 102 stops, and then the double-headed hydraulic cylinder 207 is activated. The telescopic end of the double-headed hydraulic cylinder 207 retracts, and the double-headed hydraulic cylinder 207 drives the two sets of first connecting frames 208 to move. The two sets of first connecting frames 208 drive the corresponding two sets of fixing posts 210 to move towards the steering knuckle 104, so that the fixing posts 210 are inserted into the first mounting hole 108. Through the cooperation of the two sets of fixing posts 210, one end of the steering knuckle 104 is fixed.

[0047] Then, the operator starts the first rotating device 201, which drives the mating block 202 to rotate. The mating block 202 drives the fixing component and the steering knuckle 104 to rotate until the steering knuckle 104 moves between the bearing 105 and the wheel hub 106. At this time, the second connecting block 204 and the two sets of first connecting brackets 208 are in contact with the bracket 510. Then, the operator starts the hydraulic cylinder 504. The telescopic end of the hydraulic cylinder 504 extends and drives the movable rod 503 to move until the movable rod 503 is engaged in the second mounting hole 109, thereby fixing the steering knuckle 104. At this time, the steering knuckle 104 is fixed by the support mechanism and the fixing component. The support mechanism and the fixing component fix both ends of the steering knuckle 104, so that when the bearing 105 and the wheel hub 106 are installed in the steering knuckle 104, the steering knuckle 104 will not be offset, thus ensuring that the bearing 105 and the wheel hub 106 can be smoothly installed on the steering knuckle 104.

[0048] Then, the operator activates the second rotating device 403, which drives the rotating block 404 to rotate. The rotating block 404 then drives the bearing 105 and the tensioning assembly to rotate. When the rotating block 404 rotates 180 degrees, it stops. At this point, the bearing 105 faces the steering knuckle 104. Then, the operator activates the telescopic hydraulic cylinder 408. The telescopic end of the telescopic hydraulic cylinder 408 extends, driving the push block 409 to move downward. The push block 409 pushes the bearing 105 downward. As the bearing 105 moves downward, the rubber wheel 407 rolls on the inner wall of the bearing 105. When the bearing 105 has not yet separated from the clamping block 406, one end of the bearing 105 is inserted into the steering knuckle 104 until the telescopic hydraulic cylinder 408, through the push block 409, completely presses the bearing 105 into the steering knuckle. Inside 104, the bearing 105 separates from the tensioning assembly, and the installation of the bearing 105 and the steering knuckle 104 is completed. Then, the telescopic hydraulic cylinder 408 continues to extend. At this time, due to insufficient applied pressure, the telescopic hydraulic cylinder 408 cannot drive the steering knuckle 104 to descend. At this time, the telescopic hydraulic cylinder 408 pressurizes until the pressure of the telescopic hydraulic cylinder 408 is greater than the threshold of the pressure valve 513. At this time, the telescopic hydraulic cylinder 408 can drive the steering knuckle 104 to descend. When the steering knuckle 104 descends, the cooperating mechanism works with it to ensure that the steering knuckle 104 can descend smoothly and always remain horizontal. At this time, through the descent of the steering knuckle 104, the wheel hub 106 is inserted into the bearing 105, thereby completing the installation of the steering knuckle 104, the bearing 105, and the wheel hub 106.

[0049] When the mechanism is in use, the steering knuckle 104 moves downward, causing the support mechanism and the fixing assembly to move downward simultaneously. The movable rod 503 in the support mechanism drives the slider 501 to slide in the sliding groove 502. Simultaneously, the movable rod 503 drives the first connecting rod 506 downward. At the same time, the fixing assembly, through the downward pressing bracket 510, separates the first connecting block 203 from the second connecting block 204. The limiting block 205 slides within the limiting groove 206, simultaneously causing the slider 501 to slide on the pressure valve 513. The bracket 510 then drives the third connecting rod 509 to move downward first. The first connecting rod 506 and the third connecting rod 509 simultaneously drive the connecting ring 507 to move downward. The connecting ring 507 drives the two sets of mating pins 512 to move downward. When the two sets of mating pins 512 move downward, they squeeze the hydraulic oil in the cylinder 511 into the hydraulic oil station through the pressure valve 513 and the hydraulic oil pipe 514, thereby ensuring that the steering knuckle 104 can descend smoothly. As the steering knuckle 104 and the bearing 105 move, the wheel hub 106 remains stationary. The wheel hub 106 is then installed in the bearing 105, completing the installation of the steering knuckle 104, the bearing 105, and the wheel hub 106.

[0050] After the steering knuckle 104, bearing 105, and wheel hub 106 are installed, the operator starts the hydraulic oil station and injects hydraulic oil into the cylinder 511, lifting the mating column 512. This causes the connecting ring 507, first connecting rod 506, third connecting rod 509, movable rod 503, and bracket 510 to rise, thereby lifting the steering knuckle 104, bearing 105, and wheel hub 106 as a whole. Simultaneously, the operator starts the telescopic hydraulic cylinder 408, causing its telescopic end to retract, moving the push block 409 to its initial position. At this point, the telescopic hydraulic cylinder 408 is fully retracted until the steering knuckle 104 reaches its initial position. At this point, the limit block 205 is engaged in the limit groove 206, and the first connecting block 203 is connected to the second connecting block 204. Then, the operator starts the hydraulic cylinder 504, causing its telescopic end to retract, lifting the steering knuckle 104, bearing 105, and wheel hub 106 as a whole. The movable rod 503 is moved, separating it from the second assembly hole 109. Then, the operator starts the first rotating device 201. The first rotating device 201, through the mating block 202 and the fixing component, drives the steering knuckle 104, bearing 105 and wheel hub 106 to rotate until they move above one of the feeding conveyor devices 102. Then, the double-headed hydraulic cylinder 207 is started. The double-headed hydraulic cylinder 207 drives the two sets of first connecting frames 208 and two sets of second connecting frames 209 to move. The two sets of first connecting frames 208 move away from the steering knuckle 104, separating the fixing column 210 from the first assembly hole 108 and releasing the fixing component from the steering knuckle 104. Then, the assembled steering knuckle 104, bearing 105 and wheel hub 106 are moved to the designated position by the feeding conveyor device 102 for stacking or proceeding to the next process.

[0051] After one set of steering knuckles 104 on the feeding conveyor 102 is fixed, it is moved out of the feeding conveyor 102 by the moving mechanism. At this time, the steering knuckle 104 moves in the first fixed groove 110, but the steering knuckle 104 does not contact the bottom surface or side wall of the first fixed groove 110. At this time, the feeding conveyor 102 starts and moves the other set of steering knuckles 104 to the designated position. At the same time, through the cooperation of two sets of first guide blocks 301 and two sets of second guide blocks 303, the position of the steering knuckle 104 is kept reasonable. When the steering knuckle 104 moves to the designated position, the feeding conveyor 102 stops, and the steering knuckle 104 waits to be clamped. When the tensioning assembly and the bearing 105 on the other set of feeding conveyor 102 and After the wheel hub 106 is fixed to the steering knuckle 104, it is moved out of the loading and conveying device 102 by the moving mechanism. At this time, the steering knuckle 104, bearing 105 and wheel hub 106 move in the second fixed groove 111, but do not contact the bottom or side wall of the second fixed groove 111. At this time, the operator controls the corresponding loading and conveying device 102 to move the wheel hub 106 to the designated position. When the loading and conveying device 102 drives the wheel hub 106 to move, the wheel hub 106 can move into the arc frame 601. The arc frame 601 ensures that the wheel hub 106 can always move to the appropriate position. At the same time, the operator first controls the second rotating device 403 to rotate, so that the tensioning component moves to the initial position, and then controls the moving device to move the bearing 105 onto the tensioning component.

[0052] When the tensioning assembly fixes the bearing 105, it uses several sets of rubber wheels 407 to secure the bearing 105 and prevent it from separating from the tensioning assembly. However, the rubber wheels 407 can roll between the two sets of clamping blocks 406. When the operator moves the bearing 105 with external force, the rubber wheels 407 roll on the inner wall of the bearing 105. At this time, the static friction between the rubber wheels 407 and the bearing 105 is converted into rolling friction, which makes it easier for the bearing 105 to move on the tensioning assembly without scratching the bearing 105, thus effectively preventing damage to the bearing 105.

[0053] The above descriptions are merely embodiments of the present invention, and common knowledge regarding specific structures and characteristics in the solutions is not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or its practicality.
