Description

Technical Field

[0001] This invention relates to the field of automobile manufacturing technology, specifically to a front axle balancing device for automobile assembly lines. Background Technology

[0002] On the assembly line of automobile manufacturing, the balance adjustment of the front axle is crucial. The balance of the front axle directly affects the vehicle's handling stability, ride comfort, and tire lifespan.

[0003] Publication No. CN114589486B discloses a front axle balancing device for an automobile production line, comprising: an AGV body, a hydraulic support base, a controller, a double-end translation module, scissor lifts, a front axle 11 bracket mechanism, and an infrared level; the controller is located on the outside of the AGV body; the two scissor lifts are respectively located at the front and rear moving ends of the double-end translation module; the two front axle 11 bracket mechanisms are respectively located at the lifting ends of the front and rear scissor lifts; and the two infrared levels are respectively located at the top of the front and rear front axle 11 bracket mechanisms.

[0004] Although the aforementioned automotive front axle balancing equipment on the automotive production line can automatically adjust the horizontal angle, tilt angle, and offset direction of the vehicle's front axle in multiple angles and directions, making the vehicle's front axle installation more stable, thereby achieving the purpose of front axle balancing and making the vehicle more stable, it does not require workers to use external hoisting equipment for adjustment, making the operation simple and labor-saving.

[0005] However, existing technologies can only achieve static balance adjustment, that is, simple position or angle adjustments when the front axle is stationary. In actual driving, the front axle is in dynamic operation, and static balance adjustment alone cannot accurately guarantee the stable operation of the front axle under complex conditions. Furthermore, traditional equipment has extremely limited adaptability to different specifications and sizes of vehicle frames and front axles, failing to flexibly meet diverse production needs. Moreover, its adjustment operations are usually complex, requiring significant manual intervention, which not only leads to low production efficiency but also makes it difficult to guarantee the consistency and stability of product quality. In summary, a front axle balancing adjustment device for automotive assembly lines is proposed to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a front axle balancing adjustment device for automotive assembly lines. This device can be adapted and adjusted according to the size and angle of different vehicle frames and front axles, realizing the horizontal adjustment and dynamic balance detection of the front axle, improving production efficiency and product quality, and ensuring a perfect match between the front axle and the vehicle frame.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] The technical solution provided by this invention is: a front axle balance adjustment device for automobiles on an automobile production line, comprising a bracket and a front axle, the front axle comprising a bridge rod and a wheel hub, a leveling device symmetrically provided on both sides of the bracket, an adjustment device provided on the surface of the bracket, a fixed box fixedly provided above the adjustment device, a gear-meshing support device symmetrically provided inside the fixed box, a lifting device fixedly provided above the fixed box, a clamping device fixedly provided on one side of the lifting device, a transmission device fixedly provided at one end of the clamping device, a control device fixedly provided on one side of the bracket, and a leveling instrument fixedly provided above the bracket.

[0009] Furthermore, the leveling device includes a horizontal frame fixedly installed on both sides of the support, an adjustable horizontal hydraulic rod inside the horizontal frame, and a horizontal plate fixedly installed below the horizontal hydraulic rod.

[0010] Furthermore, the adjustment device includes an adjustment groove formed on the surface of the bracket, an adjustment box fixedly installed in the adjustment groove, a dual-head adjustment motor fixedly installed in the adjustment box, an adjustment threaded rod adapted to the output end of each dual-head adjustment motor, an adjustment slide plate adapted to the thread on the surface of the adjustment threaded rod, and an electric rotary table fixedly installed above the adjustment slide plate.

[0011] Furthermore, the bottom of the fixed box is fixedly connected to the surface of the electric rotary table.

[0012] Furthermore, the support device includes a support motor fixedly installed on the inner wall of the fixed box, a drive gear adapted to the output end of the support motor, a support shaft fixedly installed below the drive gear, a support plate fixedly installed on the side of the support shaft, and a support platform fixedly installed at one end of the support plate.

[0013] A support box is fixedly installed at the other end of the support platform. A hydraulic support rod is fixedly installed inside the support box, and a support pad is fixedly installed above the hydraulic support rod.

[0014] Furthermore, the lifting device includes a lifting box fixedly installed above the fixed box, with hydraulic lifting rods symmetrically arranged inside the lifting box, and a lifting plate fixedly installed above the hydraulic lifting rods.

[0015] Furthermore, the clamping device includes a clamping plate fixedly installed on one side of the lifting plate, and elastic clamping arc plates symmetrically arranged on both sides of the clamping plate. The clamping plate and the clamping arc plates are in contact with the surface of the bridge rod. A clamping box is fixedly provided at one end of the clamping plate, and a clamping groove is provided in the clamping box. The clamping groove is movably adapted to the size of the wheel hub.

[0016] Furthermore, the transmission device includes a transmission box fixedly installed on one side of the clamping box, a transmission motor fixedly installed inside the transmission box, a transmission gear fixedly installed at the output end of the transmission motor, a transmission roller fixedly installed on one side of the transmission gear, the transmission roller being movably adapted to the clamping groove and in contact with the wheel hub, a driven gear meshing on the surface of the transmission gear, a transmission rod movably installed on one side of the driven gear, and a speed sensor fixedly installed on the other side of the driven gear, the speed sensor being in contact with the side of the wheel hub.

[0017] The beneficial effects of this technical solution are:

[0018] (1) Unlike traditional equipment that can only perform static balance adjustment, the transmission device of the present invention can drive the transmission gear to rotate after the transmission motor is running, thereby driving the transmission roller to make the hub rotate. At the same time, the speed sensor monitors the speed of the hub in real time and feeds the data back to the control device. In this way, precise dynamic balance adjustment can be achieved, which can more realistically simulate the state of the car in actual driving process. This makes the front axle balance adjustment highly consistent with actual needs, greatly improves the stability and safety of the car when driving, and effectively reduces the potential accident risk caused by front axle imbalance.

[0019] (2) The adjustment device drives the adjustment threaded rod to rotate by adjusting the double-head motor, so as to realize the symmetrical translation of the adjustment plate in the adjustment groove, and accurately adapt to the size of different frames and bridges. At the same time, the electric rotary table can make the device rotate flexibly and easily cope with frames and front axles of different angles and directions. The support device can control the support motor to drive the active gear to rotate according to the actual needs of different frames, and drive the two sets of support devices to move symmetrically in sync. The hydraulic support rod is used to adjust the height of the support pad. This series of designs makes the equipment widely adaptable to frames and front axles of various specifications, sizes and angles, greatly improving the versatility of the equipment. When producing multiple models, automobile manufacturers do not need to frequently change equipment, which reduces production costs and improves production flexibility.

[0020] (3) The leveling device can precisely adjust the extension and retraction of the horizontal hydraulic rod based on the real-time feedback of the leveling instrument, so that the leveling plate is in close contact with the ground, providing a stable horizontal foundation for the entire adjustment device. The support device can precisely adjust the support height to ensure that the frame and the front axle are kept at the same level. The transmission device, combined with the speed sensor, performs dynamic balance detection and can accurately analyze the balance state of the front axle. These precise adjustment mechanisms work together to ensure the high precision of the front axle balance adjustment. Taking tire wear as an example, the front axle after high-precision adjustment by this equipment can make the tire wear more uniform, extend the tire service life, and reduce the cost of car use.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] The specific implementation process is as follows:

[0030] Example 1:

[0031] Please see Figure 1-6 The present invention provides a technical solution: a front axle balance adjustment device for automobiles on an automobile production line, including a bracket 1 and a front axle 11. The front axle 11 includes an axle rod 1101 and a wheel hub 1102. A horizontal device 2 is symmetrically arranged on both sides of the bracket 1. An adjustment device 3 is opened on the surface of the bracket 1. A fixed box 4 is fixedly arranged above the adjustment device 3. A gear meshing support device 5 is symmetrically arranged inside the fixed box 4. A lifting device 6 is fixedly arranged above the fixed box 4. A clamping device 7 is fixedly arranged on one side of the lifting device 6. A transmission device 8 is fixedly arranged at one end of the clamping device 7. A control device 9 is fixedly arranged on one side of the bracket 1. A horizontal adjuster 10 is fixedly arranged above the bracket 1.

[0032] The horizontal device 2 is fixedly installed on both sides of the bracket 1, and the horizontal frame 201 is fixed to the bracket 1 by welding; the horizontal hydraulic rod 202 is installed in a specific mounting slot inside the horizontal frame 201, and the piston rod of the horizontal hydraulic rod 202 is connected to the horizontal plate 203 by a shaft that can be slightly adjusted in angle;

[0033] Based on the horizontal status information of the support 1 fed back by the level adjuster 10, the horizontal plate 203 is pushed or pulled by adjusting the extension length of each horizontal hydraulic rod 202, so that the horizontal plate 203 is in close contact with the ground and remains stable, thereby adjusting the level of the entire adjustment device 3, providing a stable and reliable basic platform for the precise operation of the subsequent front axle 11 balance adjustment.

[0034] The adjusting device 3 is formed on the surface of the support 1. The adjusting groove 301 is machined on the surface of the support 1. The adjusting box 302 is fixedly installed in the adjusting groove 301, which can be fastened by welding or bolts. The adjusting double-head motor is installed inside the adjusting box 302. Its output shaft is connected to the adjusting threaded rod 303 through a coupling to ensure stable power transmission. The adjusting threaded rod 303 is installed on the inner wall of the adjusting box 302 through bearings and can rotate freely. The adjusting slide plate 304 is adapted to the adjusting threaded rod 303 through threads. The electric rotary table 305 is fixedly installed above the adjusting slide plate 304, which can be fixed by bolts or welding.

[0035] When the dual-head motor is started, its output shaft drives the adjusting threaded rod 303 to rotate. Due to the threaded connection between the adjusting slide plate 304 and the adjusting threaded rod 303, the adjusting slide plate 304 will move symmetrically in the horizontal direction within the adjusting groove 301, thereby achieving precise adjustment of the horizontal position of the entire adjusting device 3 to adapt to the lateral position requirements of different frames and front axles 11. At the same time, the electric rotary table 305 can rotate freely in the horizontal direction, driving the components installed above it, such as the fixed box 4, to adjust their angles, meeting the installation and adjustment requirements of the frame and front axle 11 at different angles.

[0036] The fixed box 4 is fixed to the surface of the electric rotary table 305 by welding or bolts to ensure a stable connection. When the electric rotary table 305 rotates, the fixed box 4 can rotate synchronously.

[0037] The fixed box 4 serves as the mounting carrier for components such as the support device 5 and the lifting device 6, providing a stable mounting foundation for these components. It moves as the position and angle of the adjustment device 3 are adjusted to cooperate with the overall equipment for adjusting different front axles 11 and frames.

[0038] The support device 5 is symmetrically installed inside the fixed box 4. The support motor 505 is fixedly installed at a specific installation position on the inner wall of the fixed box 4 and fastened with bolts. The drive gear 504 is installed on the output shaft of the support motor 505 and is connected by a key to realize power transmission. The support shaft 503 is installed inside the fixed box 4 through bearings and meshes with the drive gear 504 to ensure that the drive gear 504 can drive the support shaft 503 to rotate synchronously when it rotates. The support plate 502 is fixedly installed on the side of the support shaft 503 and is connected by welding or bolts. The support platform 501 is installed on one end of the support plate 502 and is also fixed by welding or bolts. The support box 506 is fixed on the other end of the support platform 501. The hydraulic support rod 507 is installed inside the support box 506 and its piston rod is connected to the support pad 508 by welding or thread.

[0039] When the control device 9 starts the support motor 505, the output shaft of the support motor 505 drives the drive gear 504 to rotate. The rotation of the drive gear 504 drives the symmetrically set support devices 5 to move synchronously and symmetrically. The drive gear 504 is fixedly connected to the support shaft 503, causing the support shaft 503 to rotate, which in turn drives the support plate 502 and the support platform 501 to move horizontally. By controlling the synchronous and symmetrical movement of the two sets of support devices 5, the support position can be adjusted to align with the support points of different frames. At the same time, the hydraulic support rod 507 can adjust the extension length of its piston rod according to the actual height requirements of the frame and the front axle 11, thereby driving the support pad 508 to rise or fall, providing stable support for the frame and keeping the frame and the front axle 11 at the same horizontal height, providing stable support for the installation and balance adjustment of the front axle 11.

[0040] The lifting device 6 is fixedly installed above the fixed box 4. The lifting box 601 is connected to the fixed box 4 by welding or bolts. The hydraulic lifting rod 602 is symmetrically installed inside the lifting box 601. Its cylinder body is fixed to the lifting box 601 by bolts or welding. The piston rod is connected to the lifting plate 603 by welding or high-strength bolts.

[0041] The extension and retraction of the hydraulic lifting rod 602 is controlled by the control device 9. The piston rod of the hydraulic lifting rod 602 pushes or pulls the lifting plate 603 to move up and down, thereby precisely adjusting the height of the front axle 11. This allows the front axle 11 to quickly and accurately reach the appropriate height position when it is installed with the vehicle frame, facilitating the docking and installation operation of the two.

[0042] The clamping device 7 is fixedly installed on one side of the lifting plate 603. The clamping plate 701 is connected to the lifting plate 603 by welding or bolts. The clamping arc plate 702 is symmetrically installed on both sides of the clamping plate 701 by elastic connecting parts, such as springs, so as to ensure the clamping force on the bridge rod 1101 and adapt to bridge rods 1101 of different diameters. The clamping box 703 is fixedly installed on one end of the clamping plate 701 by welding or bolts. The clamping groove 704 is formed inside the clamping box 703.

[0043] The clamping plate 701 and the elastic clamping arc plate 702 are used to tightly fit the surface of the bridge rod 1101 to firmly clamp the bridge rod 1101 and prevent the front axle 11 from shifting during the adjustment process. At the same time, the wheel hubs 1102 at both ends of the bridge frame are placed in the clamping grooves 704 in the clamping box 703. The clamping grooves 704 are adapted to the size of the wheel hubs 1102 to further stabilize the position of the front axle 11 and ensure the stability of the front axle 11 in subsequent dynamic balance testing and other operations.

[0044] The transmission device 8 is fixedly installed on one side of the clamping box 703. The transmission box 801 is connected to the clamping box 703 by welding or bolts. The transmission motor 802 is fixedly installed inside the transmission box 801, and its output shaft is connected to the transmission gear 803 by a key. The transmission roller is installed on one side of the transmission gear 803 and is fixedly connected to the transmission gear 803 on the same axis. The driven gear 804 is meshed with the transmission gear 803 and is installed on a specific shaft inside the transmission box 801, and can rotate freely through bearings. The transmission rod 805 is movably installed on one side of the driven gear 804, and the speed sensor 806 is fixedly installed on the other side of the driven gear 804, and its sensing end is in contact with the side of the hub 1102.

[0045] After the drive motor 802 starts, the output shaft drives the drive gear 803 to rotate, and the drive gear 803 drives the coaxial drive roller to rotate. Since the drive roller is in contact with the wheel hub 1102, it drives the wheel hub 1102 to rotate, simulating the dynamic operation state of the front axle 11 when the car is moving. During the rotation of the drive gear 803, the driven gear 804 meshing with it rotates synchronously. The driven gear 804 drives the speed sensor 806 to rotate. The speed sensor 806 monitors the rotation speed of the wheel hub 1102 in real time and feeds the data back to the control device 9, providing data support for the dynamic balance detection of the front axle 11, so that the control device 9 can judge the balance state of the front axle 11 based on the rotation speed data and make corresponding adjustments.

[0046] The control device 9 is fixedly installed on one side of the bracket 1 and is connected to the horizontal hydraulic rod 202 of the horizontal device 2, the adjusting double-head motor and electric rotary table 305 of the adjusting device 3, the support motor 505 and hydraulic support rod 507 of the support device 5, the hydraulic lifting rod 602 of the lifting device 6, and the transmission motor 802 of the transmission device 8 via wires to realize the transmission of control signals to these devices; the leveling instrument 10 is fixedly installed above the bracket 1 and is connected to the control device 9 via a data cable to transmit the monitored horizontal status data of the bracket 1 to the control device 9 in real time;

[0047] As the core of the entire equipment, the control device 9 receives the horizontal status data of the support 1 from the leveling device 10 and the rotational speed data of the wheel hub 1102 from the speed sensor 806. According to the preset program and algorithm, it issues control commands to various devices such as the leveling device 2, the adjusting device 3, the supporting device 5, the lifting device 6, and the transmission device 8, coordinating the operation of each device to achieve precise balance adjustment of the front axle 11. The leveling device 10 monitors the horizontal status of the support 1 in real time, providing accurate horizontal data to the control device 9 to ensure that the equipment performs balance adjustment of the front axle 11 in a horizontal state, thereby improving the adjustment accuracy.

[0048] Working principle: Place bracket 1 in a suitable position on the automobile production line, connect the power supply and hydraulic system; start the control device 9, monitor the horizontal status of bracket 1 through the leveling instrument 10, adjust the horizontal hydraulic rod 202 of the leveling device 2 to make the leveling plate 203 in close contact with the ground, and ensure that bracket 1 is in a horizontal position.

[0049] Based on the size and angle of the chassis and front axle 11, the control device 9 starts the adjustment dual-head motor of the adjustment device 3, drives the adjustment threaded rod 303 to rotate, and causes the adjustment slide plate 304 to move symmetrically within the adjustment groove 301 to adjust the horizontal position; at the same time, the electric rotary table 305 is started to rotate the device to a suitable angle to adapt to the orientation of the chassis and front axle 11.

[0050] The front axle 11 of the vehicle is placed on the equipment, so that the axle rod 1101 contacts the clamping plate 701 and the clamping arc plate 702 of the clamping device 7, and the wheel hub 1102 is placed in the clamping groove 704.

[0051] Start the support motor 505 of the support device 5, control the drive gear 504 to rotate, drive the gears meshing on one side to rotate synchronously in opposite directions, so that the two sets of support devices 5 move synchronously and symmetrically, adjust the position of the support plate 502 and the support platform 501, and align them with the support point of the frame.

[0052] Start the hydraulic support rod 507 of the support device 5, adjust the height of the support pad 508 to support the frame and keep the frame and front axle 11 at the same level.

[0053] Start the hydraulic lifting rod 602 of the lifting device 6, and adjust the height of the front axle 11 as needed to facilitate its installation with the vehicle frame;

[0054] The drive motor 802 of the transmission device 8 is started, which drives the transmission gear 803 to rotate. The transmission gear 803 drives the transmission roller to rotate, thereby causing the wheel hub 1102 to rotate. The speed sensor 806 monitors the rotation speed of the wheel hub 1102 in real time and feeds the data back to the control device 9. The control device 9 analyzes the balance state of the front axle 11 based on the feedback data. If the front axle 11 is unbalanced, the control device 9 adjusts the angle of the leveling device 2 to balance the front axle 11 until the balance requirement is met.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention.
