Description

Technical Field

[0001] This invention relates to the field of commercial vehicle manufacturing technology, and more specifically, to a device for removing and installing a front suspension mount on a commercial vehicle cab. Background Technology

[0002] In the existing technology, the front suspension assembly tool is difficult to compensate for the assembly error during the disassembly and assembly of the front suspension of the cab. The alignment of the assembly holes depends on manual judgment, which is inaccurate and inefficient.

[0003] There is currently no effective solution to the aforementioned technical problems. Summary of the Invention

[0004] The main objective of this invention is to provide a device for removing and assembling the front suspension of a commercial vehicle cab, so as to solve the problems of low efficiency and poor assembly accuracy of the front suspension removal and assembly in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, a front suspension mounting and dismounting device for a commercial vehicle cab is provided, comprising: a base, the base including a base and a support platform, the distance between the base and the support platform being relatively adjustable along the height direction of the base; a clamping assembly connected to the support platform, the clamping assembly including a support bracket and a clamping member, at least a portion of the support bracket extending along the length direction of the base, the support bracket being movably disposed on the support platform, the space between the support bracket and the clamping member forming a clamping area, the clamping area being used to clamp the front suspension stabilizer bar; wherein, the clamping member is movably disposed on the support bracket along the extension direction of the support bracket, the clamping member having a clamping state moving away from the connecting end of the support bracket, and a releasing state moving toward the connecting end of the support bracket.

[0006] Furthermore, a support rod protrudes from the end of the support bracket away from the support platform, and a slide is provided on the support bracket. The clamping component is slidably mounted on the slide. The support rod is used to connect with the front suspension stabilizer bar, and a clamping area is formed between the support rod and the clamping component.

[0007] Furthermore, the commercial vehicle cab front suspension mounting and dismounting equipment also includes a control component, which includes: a first drive unit connected to a support platform and disposed on one side of the support platform; a connecting end of a support bracket connected to the first drive unit; the support bracket being movably disposed on the first drive unit along the width direction of the base; and the first drive unit being used to drive the support bracket to move along the width direction of the base; and a second drive unit, one end of which is connected to the connecting end of the support bracket, and the other end of which is connected to a clamping component; the second drive unit being used to drive the clamping component to be in a clamping state and a releasing state.

[0008] Furthermore, the control component also includes: an image acquisition unit, which is disposed on the support platform and is used to acquire position information of at least one of the support bracket and the front suspension stabilizer; and a control unit, which is connected to at least one of the base and the support platform, and is electrically connected to the image acquisition unit, the first drive member, and the second drive member, and is used to control the movement of the support bracket and the clamping member.

[0009] Furthermore, the commercial vehicle cab front suspension mounting and dismounting equipment also includes a dynamic compensation component. The support platform includes an upper support platform and a lower support platform. The dynamic compensation component is located between the upper support platform and the lower support platform. The upper support platform and the lower support platform are rotatably connected through the dynamic compensation component. The dynamic compensation component has a locked state that locks the upper support platform and the lower support platform, and also has an unlocked state.

[0010] Furthermore, the dynamic compensation component includes an upper connecting seat, a lower connecting seat, and a steering shaft. One end of the upper connecting seat is connected to the upper support platform, and one end of the lower connecting seat is connected to the lower support platform. The upper and lower connecting seats are rotatably connected to each other via the steering shaft. The steering shaft is electrically connected to the control unit, which is used to control the steering shaft to be in a locked state and an unlocked state.

[0011] Furthermore, the dynamic compensation component also includes a sensor, which is connected to at least one of the upper connecting seat and the steering shaft, and is electrically connected to the control unit. The sensor is used to obtain the direction and magnitude of the force on the support platform.

[0012] Furthermore, the commercial vehicle cab front suspension mounting and dismounting equipment also includes a support assembly, one end of which is connected to the lower support platform and the other end of which is connected to the base. The support assembly is movably arranged along the height direction of the base so that the lower support platform has a raised state away from the base along the height direction of the base, and a retracted state close to the base.

[0013] Furthermore, the support assembly includes: a push rod, one end of which is connected to the lower support platform and the other end of which is connected to the base; the push rod is electrically connected to the control unit and is used to push the lower support platform to move along the height direction of the base; and a connecting rod, one end of which is connected to the lower support platform and the other end of which is connected to the base and is used to provide the required support force for the lower support platform.

[0014] Furthermore, the commercial vehicle cab front suspension mounting and dismounting equipment also includes a moving component, which is connected to the base and is located on the bottom side of the base. The moving component is used to move the base.

[0015] Applying the technical solution of this invention, the commercial vehicle cab front suspension mounting and dismounting device is designed so that the base and support platform are relatively adjustable along the height direction of the base to adapt to different models and sizes of cab chassis. A clamping assembly is provided on the support platform, including a support bracket and clamping elements. By movably mounting the support bracket on the support platform, after the support platform is adjusted to the corresponding height, the support bracket can be further adjusted to move on the support platform to align with the stabilizer bar of the cab front suspension. This allows the support bracket to provide support and clamping force to the stabilizer bar, facilitating stable fixation of the front suspension. Simultaneously, a clamping area is formed between the support bracket and the clamping elements. When the support bracket supports the front suspension, the front suspension is within the clamping area. At this time, the clamping elements can move along the extension direction of the support bracket until they abut against the front suspension, adjusting the clamping elements to a clamping state. This further clamps and fixes the front suspension, ensuring stable fixation during the mounting and dismounting of the cab front suspension, preventing wobbling, improving assembly and disassembly efficiency, and ensuring assembly accuracy. This also avoids the problems of high labor intensity, low efficiency, and safety hazards associated with manually lifting and suspending the pre-positioned feature parts in traditional technologies.

[0030] Combination Figure 1 , Figure 2 As shown in the specific embodiment of this application, a front suspension mounting and dismounting device for a commercial vehicle cab is provided.

[0031] Specifically, such as Figure 1As shown, the commercial vehicle cab front suspension mounting and dismounting device includes a base 10 and a clamping assembly 20. The base 10 includes a base 11 and a support platform 12. The distance between the base 11 and the support platform 12 is adjustable relative to each other along the height direction of the base 11. The clamping assembly 20 is connected to the support platform 12 and includes a support bracket 21 and a clamping member 22. At least a portion of the support bracket 21 extends along the length direction of the base 11. The support bracket 21 is movably mounted on the support platform 12. The space between the support bracket 21 and the clamping member 22 forms a clamping area 200, which is used to clamp the front suspension stabilizer bar. The clamping member 22 is movably mounted on the support bracket 21 along the extension direction of the support bracket 21. The clamping member 22 has a clamping state where it moves away from the connecting end of the support bracket 21, and a releasing state where it moves toward the connecting end of the support bracket 21.

[0032] Applying the technical solution of this embodiment, the commercial vehicle cab front suspension mounting and dismounting device is configured such that the base 11 and the support platform 12 are relatively adjustable along the height direction of the base 11 to adapt to different models and sizes of cab chassis. A clamping assembly 20 is provided on the support platform 12, comprising a support bracket 21 and clamping elements 22. By movably mounting the support bracket 21 on the support platform 12, after the support platform 12 is adjusted to the corresponding height, the support bracket 21 can be further adjusted to move on the support platform 12 to align with the stabilizer bar of the cab front suspension. This allows the support bracket 21 to provide support and clamping force to the stabilizer bar, facilitating stable fixing of the front suspension. Simultaneously, a clamping area 200 is formed between the support bracket 21 and the clamping member 22. When the support bracket 21 supports the front suspension, the front suspension is within the clamping area 200. At this time, the clamping member 22 can move along the extension direction of the support bracket 21 until it abuts against the front suspension, thereby adjusting the clamping member 22 to a clamping state. The clamping member 22 can then further clamp and fix the front suspension, ensuring stable fixation during the assembly and disassembly of the cab front suspension, preventing wobbling, improving assembly and disassembly efficiency, and ensuring assembly accuracy. This also avoids the problems of high labor intensity, low efficiency, and safety hazards associated with manually lifting the front suspension's key parts in traditional technologies.

[0033] It should be noted that, due to the adjustable configuration of the support platform 12, support bracket 21 and clamping component 22, the commercial vehicle cab front suspension mounting and dismounting equipment can clamp and fix the front suspension according to the different models and sizes of the cab front suspension, thus improving the equipment's versatility and flexibility.

[0034] Specifically, a support rod 23 protrudes from the end of the support bracket 21 away from the support platform 12. A slide table 24 is provided on the support bracket 21, and the clamping member 22 is slidably mounted on the slide table 24. The support rod 23 is used to connect with the front suspension stabilizer bar, and a clamping area 200 is formed between the support rod 23 and the clamping member 22. The support rod 23 is used to connect with the front suspension stabilizer bar or feature structure to ensure the fixation and support of the front suspension during the assembly and disassembly process. At the same time, by providing a slide table 24 on the support bracket 21, the clamping member 22 can slide along the slide table 24, so that the position of the clamping member 22 can be adjusted to a clamping state or a released state according to specific operation requirements. Furthermore, the cooperation between the support rod 23 and the clamping member 22 further stabilizes the clamping of the front suspension, thereby ensuring that the front suspension can be stably fixed within the clamping area 200 when removing or installing bolts, reducing instability factors during operation, and improving operation safety and efficiency.

[0035] In one exemplary embodiment of this application, the support bracket 21 is configured with a cavity structure, and a transmission component such as a cylinder, hydraulic cylinder, or gear rack is provided in the cavity. The support rod 23 is connected to the transmission component in the cavity, so that the support bracket 21 can drive the adjustment support rod 23 to move or rotate, thereby allowing the support rod 23 to extend into the U-shaped slot or feature hole of the front suspension, realizing a stable connection between the support rod 23 and the front suspension, and preventing the support bracket 21 from detaching from the front suspension during the clamping process of the device.

[0036] In this embodiment, the support rod 23 is detachably connected to the support bracket 21, allowing the support rod 23 to be replaced with a matching structure when the front suspension of the equipment is designed for different models or structures, further improving the versatility and flexibility of the equipment. Simultaneously, when the support rod 23 malfunctions or is damaged, it can be quickly replaced, improving equipment maintenance and disassembly / reassembly efficiency.

[0037] Furthermore, the commercial vehicle cab front suspension mounting and dismounting equipment also includes a control component 30. The control component 30 includes a first drive member 31 and a second drive member 32. The first drive member 31 is connected to the support platform 12 and is disposed on one side of the support platform 12. The connecting end of the support bracket 21 is connected to the first drive member 31. The support bracket 21 is movably disposed on the first drive member 31 along the width direction of the base 11. The first drive member 31 is used to drive the support bracket 21 to move along the width direction of the base 11. One end of the second drive member 32 is connected to the connecting end of the support bracket 21, and the other end of the second drive member 32 is connected to the clamping member 22. The second drive member 32 is used to drive the clamping member 22 to be in a clamping state and a releasing state. The first drive unit 31 adjusts the movement of the support bracket 21 along the width direction of the base 11. Connected to the support platform 12, the first drive unit 31 ensures stability during movement. When the position of the support bracket 21 needs adjustment to accommodate cab front suspensions of different widths, the first drive unit 31 activates, moving the support bracket 21 along the width direction of the base 11 until a suitable clamping position is reached. Similarly, the second drive unit 32 adjusts the clamping member 22 to be in a clamped or released state according to the length of the front suspension, thus adjusting the clamping member 22's grip on the front suspension. By using the first drive unit 31 and the second drive unit 32 to adjust the support bracket 21 and clamping member 22, operation is simple, reducing physical exertion on operators, improving operational safety, flexibly adapting to the needs of cabs of different widths, and improving versatility and operational efficiency.

[0038] It should be noted that both the first driving component 31 and the second driving component 32 can use transmission components such as cylinders, hydraulic cylinders, and gear racks to control the movement of the support bracket 21 and the clamping component 22.

[0039] In one embodiment of this application, both the first drive member 31 and the second drive member 32 are driven by a lead screw and nut. The screw and nut are tightly fitted, and by controlling the rotation angle of the motor, very precise linear displacement can be achieved. The mechanism is simple in structure, easy to maintain, and can provide stable power transmission.

[0040] Specifically, the control component 30 also includes an image acquisition unit 33 and a control unit. The image acquisition unit 33 is mounted on the support platform 12 and is used to acquire position information of at least one of the support bracket 21 and the front suspension stabilizer bar. The control unit is connected to at least one of the base 11 and the support platform 12, and is electrically connected to the image acquisition unit, the first drive member 31, and the second drive member 32. The control unit is used to control the movement of the support bracket 21 and the clamping member 22. By setting up the image acquisition unit 33 and the control unit, the image acquisition unit 33 can acquire position images of components such as the front suspension and the support bracket 21, and transmit the image information to the control unit in the form of electrical signals. The control unit can analyze and calculate the optimal movement trajectory that the support bracket 21 and the clamping member 22 should take based on the image information and combined with the built-in control algorithm, and control the first drive member 31 and the second drive member 32 to adjust the support bracket 21 and the clamping member 22 to the correct position, ensuring the safety and efficiency of the operation. By combining the image acquisition unit 33 with the control unit, intelligent operation of the equipment is realized, reducing the complexity and risk of manual operation, ensuring high precision and efficiency of the front suspension disassembly and assembly operations, and significantly improving the intelligence level and practicality of the equipment.

[0041] Furthermore, such as Figure 2As shown, the commercial vehicle cab front suspension mounting and dismounting equipment also includes a dynamic compensation component 40. The support platform 12 includes an upper support platform 121 and a lower support platform 122. The dynamic compensation component 40 is disposed between the upper support platform 121 and the lower support platform 122. The upper support platform 121 and the lower support platform 122 are rotatably connected via the dynamic compensation component 40. The dynamic compensation component 40 has a locked state where the upper support platform 121 and the lower support platform 122 are locked, and it also has an unlocked state. By setting the dynamic compensation component 40 between the upper support platform 121 and the lower support platform 122, the dynamic compensation component 40 allows the connection between the upper support platform 121 and the lower support platform 122 to allow for a certain degree of relative rotation. During the disassembly and assembly of the front suspension, the front suspension components at the bottom of the cab may experience slight displacement or posture changes due to external forces (such as manual operation, vehicle weight, etc.) or different sizes and models. The dynamic compensation component 40 can respond in real time, maintaining its vertical support to the bottom of the cab by finely adjusting the posture of the upper support platform 121, thereby compensating for assembly errors and improving operational accuracy. After the dynamic compensation component 40 adjusts the angle according to the force on the upper support platform 121, it can automatically lock the rotation state. That is, the dynamic compensation component 40 can switch between a locked state and an unlocked state. In the locked state, the relative rotation between the upper support platform 121 and the lower support platform 122 is locked, forming a rigid connection to provide a stable support platform 12, suitable for equipment movement and initial positioning. When the equipment is in place and disassembly and assembly work begins, the dynamic compensation component 40 switches to the unlocked state, allowing the upper support platform 121 to rotate freely relative to the lower support platform 122 to adapt to the dynamic changes of the cab and achieve automatic compensation. The real-time response capability of the dynamic compensation component 40 reduces unexpected pressure or torsion caused by changes in cab posture, lowers the risk of component damage or personnel injury during operation, and significantly enhances operational safety.

[0042] Specifically, the dynamic compensation component 40 includes an upper connecting seat 41, a lower connecting seat 42, and a steering shaft 43. One end of the upper connecting seat 41 is connected to the upper support platform 121, and one end of the lower connecting seat 42 is connected to the lower support platform 122. The upper connecting seat 41 and the lower connecting seat 42 are rotatably connected relative to each other via the steering shaft 43. The steering shaft 43 is electrically connected to a control unit, which controls the steering shaft 43 to be in a locked state and an unlocked state. In the locked state, the steering shaft 43 uses a built-in braking or locking mechanism to fix the upper connecting seat 41 and the lower connecting seat 42 together, preventing any relative rotation. When the equipment reaches the working position and the front suspension needs to be removed or installed, the control unit switches the steering shaft 43 to the unlocked state. In this state, the steering shaft 43 allows relative rotation between the upper connecting seat 41 and the lower connecting seat 42. This dynamic compensation capability is achieved through a built-in servo motor. The motor automatically adjusts the angle of the steering shaft 43 based on data acquired from the image acquisition unit 33 and other sensors to compensate for posture changes caused by uneven weight distribution in the cab or minor deformation during assembly and disassembly. When a tendency for displacement of the front suspension component at the bottom of the cab is detected, the steering shaft 43 reacts in real time, adjusting the posture of the upper support platform 121 through a slight rotation to ensure that the upper support platform 121 remains perpendicular to the bottom of the cab, thereby maintaining the stability of the support system and the precise positioning of components. By compensating for minor displacement of the cab, the possibility of accidents during operation is reduced, such as damage to components due to uneven pressure or injury to personnel, increasing the safety of the entire operation. Simultaneously, the steering shaft 43 is electrically connected to the control unit, enabling the dynamic compensation component 40 to automatically adjust its working state based on real-time data, achieving intelligent switching between locking and unlocking, further enhancing the automation and intelligence level of the equipment.

[0043] Furthermore, the dynamic compensation component 40 also includes a sensor, which is connected to at least one of the upper connecting seat 41 and the steering shaft 43. The sensor is electrically connected to the control unit and is used to acquire the direction and magnitude of the force on the support platform 12. The sensor may include a force sensor and an angle sensor. The force sensor is used to measure the magnitude and direction of the force acting on the upper support platform 121, enabling the control unit to understand the current load-bearing state of the support platform and determine whether attitude adjustment is needed through the dynamic compensation component 40 to maintain the vertical relationship between the support platform and the bottom of the cab, reducing displacement or tilting caused by load changes. The angle sensor is used to detect the relative rotation angle of the upper support platform 121 relative to the lower support platform 122. By monitoring the rotation state of the steering shaft 43, the control unit can grasp the current dynamic compensation amount in real time, ensuring that the compensation action is appropriate and timely, and avoiding instability caused by over-adjustment.

[0044] In this embodiment, the force direction and magnitude data collected in real time by the sensors are transmitted to the control unit via an electrical connection. Based on this data and the position information provided by the image acquisition unit 33, the control unit can analyze the current dynamic changes in the cab using a built-in algorithm and determine the working status of the dynamic compensation component 40. If the detected force indicates displacement or attitude change at the bottom of the cab, the control unit will adjust the working mode of the dynamic compensation component 40 and fine-tune the tilt angle of the upper support platform 121 by controlling the motor of the steering shaft 43 to compensate for the change and ensure the stability of the support platform and the accuracy of operation.

[0045] Furthermore, the commercial vehicle cab front suspension removal and installation equipment also includes a support assembly 50. One end of the support assembly 50 is connected to the lower support platform 122, and the other end is connected to the base 11. The support assembly 50 is movably arranged along the height direction of the base 11, so that the lower support platform 122 has a raised state away from the base 11 along the height direction of the base 11, and a retracted state close to the base 11. The support assembly 50 can move along the height direction of the base 11, which can drive the lower support platform 122 to be raised and lowered. The raised state means that the lower support platform 122 is raised by the support assembly 50 to a height away from the base 11 to adapt to the cab of the high chassis or to perform front suspension removal and installation operations; while the retracted state means that the lower support platform 122 is lowered to a position close to the base 11 for easy storage or movement of the equipment.

[0046] Optionally, the support assembly 50 can employ various drive mechanisms, such as electric actuators, hydraulic cylinders, or screw jacks, to achieve its longitudinal movement capability. When the equipment is in place and ready to begin operation, the operator issues a command through the control unit to drive the actuators or cylinders of the support assembly 50 to extend, thereby raising the lower support platform 122 to the appropriate height.

[0047] Specifically, the support assembly 50 includes a push rod 51 and a connecting rod 52. One end of the push rod 51 is connected to the lower support platform 122, and the other end is connected to the base 11. The push rod 51 is electrically connected to the control unit and is used to push the lower support platform 122 to move along the height direction of the base 11. One end of the connecting rod 52 is connected to the lower support platform 122, and the other end is connected to the base 11. The connecting rod 52 is used to provide the required support force for the lower support platform 122. The support assembly 50 achieves precise control of the height of the lower support platform 122 through the push rod 51 and the connecting rod 52. At the same time, the push rod 51 is electrically connected to the control unit, allowing the operator to remotely adjust the height of the lower support platform 122, ensuring that the equipment can adapt to the height requirements of various working scenarios. The connecting rod 52 provides the necessary support for the lower support platform 122, ensuring that the lower support platform 122 can work stably at any height. Especially when the push rod 51 lifts the lower support platform 122, the connecting rod 52 can provide additional stability and safety, avoiding instability caused by load changes or movement.

[0048] Furthermore, the commercial vehicle cab front suspension mounting and dismounting equipment also includes a moving component 60, which is connected to the base 11 and is located on the bottom side of the base 11. The moving component 60 is used to move the base 11. By connecting to the base 11, the moving component 60 can be quickly moved between different work points without manual handling, thus significantly saving work preparation time and physical labor.

[0049] In one embodiment of this application, the moving component 60 is composed of an electric omnidirectional wheel system. The electric omnidirectional wheels can move omnidirectionally in all directions within a plane, including forward, backward, left, and right, and have the ability to rotate in place. This allows the equipment to flexibly turn in confined spaces and adapt to various complex working environments. The servo motors and differential control mechanisms incorporated in the electric omnidirectional wheels allow the equipment to intelligently plan its movement path and achieve autonomous positioning through commands from the control unit.

[0050] This application also provides a preferred embodiment of a commercial vehicle cab front suspension removal and installation device to solve problems such as high labor intensity, low removal and installation efficiency, difficulty in accurately aligning assembly holes, and inability to adapt to the dynamic posture of different models of cabs, thereby achieving fast, accurate, and safe removal and installation of front suspensions for multiple models of commercial vehicles.

[0051] Specifically, the commercial vehicle cab front suspension mounting and dismounting equipment includes a base 10 and a moving component 60. The moving component 60 consists of casters. The base 10 includes a support platform 12 and a base 11. The base 11 is a rigid welded frame, with a caster mounted at each of the four corners of the frame's bottom. The casters are driven by independent servo motors and can receive commands from the central control unit, achieving omnidirectional movement in the plane (forward, backward, left, right, diagonal, and rotational) through differential speed control. One or two electric push rods 51 are vertically mounted in the center of the base 11. The top of the push rods 51 are connected to the upper support platform 12. The support platform 12 constitutes the upper working plane of the entire equipment, used for mounting the clamping component 20 and the control component 30.

[0052] The implementation process is as follows: the operator selects the target equipment, the control system can call the preset program to automatically plan the movement path, the equipment is located by scanning with a camera, and autonomously drives to the optimal working position at the bottom of the cab. After arriving at the position, the casters lock and brake. Then the control unit sends a command, and the electric push rod 51 moves synchronously to precisely lift the support platform 12 to the required working height of the equipment. The height data can be obtained from the equipment database to ensure that the tool of the support bracket 21 can be aligned with the suspension mounting point.

[0053] The dynamic compensation component 40 is mounted on the support platform 12 and includes an electrically driven steering shaft 43, which integrates a servo motor to drive the upper connecting seat 41 to rotate slightly within ±10° in the horizontal plane. The upper end of the steering shaft 43 is connected to the upper connecting seat 41, and the lower end is connected to the lower connecting seat 42 via a bearing. The upper connecting seat 41 is connected to the upper support platform 121, which is used to mount the clamping component 20. The dynamic compensation component 40 integrates a force sensor and an angle sensor.

[0054] The implementation process is as follows: After the clamping assembly 20 contacts and initially clamps the cab suspension point, the dynamic compensation assembly 40 is activated and enters the floating compensation mode. At this time, the electric steering shaft 43 is no longer rigidly locked, and the angle of the upper connecting seat 41 is finely adjusted in real time according to the force feedback from the force sensor. When the operator removes or installs bolts, the cab may experience slight subsidence or displacement. The dynamic compensation assembly 40 can automatically adapt to the changes, always maintaining the support force vertically upward, avoiding lateral stress on the cab floor or suspension components, and greatly improving docking accuracy and operational safety.

[0055] The clamping assembly 20 and control assembly 30 are mounted as a single unit on the support platform 12, comprising three cooperating subsystems. A pair of support brackets 21 are mounted via connecting blocks on a lead screw with two threads of opposite directions and a smooth central rod, driven by a motor. The forward and reverse rotation of the lead screw causes the two support brackets 21 to move in opposite directions, thereby enabling the retraction and expansion of the two support brackets 21 to accommodate front overhangs of cabs of different widths. An image acquisition unit 33 is located at the end of the support platform 12 for observing the relative position of the support brackets 21 and the base 11. The support rod 23 and the clamping component 22 provide additional structural stability and safety protection.

[0056] The implementation process is as follows: After the equipment is in place, the motor drives the lead screw according to the equipment parameters to adjust the spacing of the support bracket 21 to the target width. The operator fine-tunes the equipment position through real-time image and video feedback so that the support bracket 21 is accurately inserted under the support point at the bottom of the cab.

[0057] The shape of the support rod 23 matches the contour of the front stabilizer bar. The clamping member 22 is mounted on a slide table 24 consisting of a lead screw and a nut, and is driven by another motor to achieve precise movement in the front and rear directions. The image acquisition unit at the rear end of the support platform 12 is used to observe whether the stabilizer bar enters the bracket slot.

[0058] The implementation process is as follows: after the support bracket 21 is in place, the motor drives the clamping component 22 to move forward until the camera recognizes that the stabilizer bar has accurately fallen into the contour groove of the bracket, thus completing the limitation of the cab in the front and rear directions and preventing it from swaying back and forth during disassembly.

[0059] The clamping power comes from the cylinder, which is connected to the compressed air source through an air pipe, a three-way valve, and a pneumatic control valve. The camera is aimed at the clamping point for final status confirmation and safety monitoring.

[0060] The implementation process is as follows: After the clamping component 20 and the control component 30 are positioned and supported, the system is activated, pushing the support rod 23 to tightly grip the front suspension assembly. The operator confirms that the suspension assembly is clamped through the image transmitted by the camera. At this time, the front suspension of the cab is supported by the equipment and is effectively constrained in all degrees of freedom, allowing the operator to safely remove and install bolts.

[0061] The control method for the commercial vehicle cab front suspension mounting and dismounting device in the above embodiments is as follows:

[0062] Step 1, Equipment positioning and overall movement adjustment: Activate the electric caster system to move the equipment to the target workstation. Adjust the front, back, left and right positions through the control unit, operate the electric push rod, and work with the connecting rod 52 and the support platform 12 to complete the equipment height adjustment;

[0063] Step 2, Adaptive floating state simulation and connection: Activate the electric steering shaft 43, the upper connecting seat 41 and the lower connecting seat 42 automatically match the initial posture of the cab, the control unit finely adjusts the angle in real time, compensates for assembly errors, realizes flexible docking, and improves safety;

[0064] Step 3, front suspension clamping and support system adaptation settings: Select the corresponding support rod 23 according to the vehicle model information and install it in place, start the first drive component 31, adjust the spacing of the support bracket 21 to match the cab width, start the camera, and confirm that the support bracket 21 is accurately positioned without interference;

[0065] Step 4, Precise support of the front stabilizer bar and the front suspension: Adjust the clamping assembly 20 of the front stabilizer bar, and achieve forward and backward positioning through the second drive component 32. The pneumatic valve is activated, and the cylinder is supplied with air through the air pipe and the three-way valve to quickly clamp the front suspension and complete the fixation. The camera confirms the clamping status and safety limit again.

[0066] Step 5, Status Confirmation and Work Completion: Check the image acquisition unit and signal feedback to confirm that all connection points are under uniform force and there are no abnormal alarms. Record the parameters of this operation for future reference and optimization.

[0067] As can be seen from the above description, the commercial vehicle cab front suspension mounting and dismounting device in the above embodiments has the following beneficial effects:

[0068] 1) Automation and efficiency: It completely replaces manual lifting and positioning operations, improving disassembly and assembly efficiency by more than 50%.

[0069] 2) Safety: Avoiding the risks of manual operation, the risk of component damage and personnel injury is reduced by 90% through real-time monitoring by sensors and cameras.

[0070] 3) Precision: The alignment accuracy of the assembly holes is controlled within ±1mm, which greatly improves the assembly quality.

[0071] 4) Adaptability: Modular and replaceable structure, covering the front suspension installation and removal of cabs for all mainstream commercial vehicle models.
