[0002] In the commercial vehicle assembly line, the positioning and stabilization of the cab are key links, directly affecting the accuracy and efficiency of subsequent assembly work. Traditional cab positioning methods mainly rely on the positioning mechanism between the cab lifting tool and the vehicle body, indirectly stabilizing the cab by fixing the lifting tool. However, this method has limitations in actual operation. There is a soft connection between the cab and the vehicle body, resulting in possible slight displacement of the cab even after the lifting tool is fixed. Especially during precise operations in the assembly process, such as installing heat insulation pads and tightening nuts, the slight displacement may affect the assembly quality.

[0003] In view of the above technical problems, no effective solution has been proposed yet. Summary of the Invention

[0036] Now, exemplary embodiments according to the present application will be described in more detail with reference to the drawings. However, these exemplary embodiments can be implemented in many different forms and should not be construed as being limited only to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present application is thorough and complete, and the concept of these exemplary embodiments is fully conveyed to those of ordinary skill in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and thus their descriptions will be omitted.

[0037] Combined with Figures 1 to 4 As shown, according to a specific embodiment of the present application, a cab fixing system is provided.

[0038] Specifically, as Figure 1 、 Figure 3 shown, the cab fixing system includes a lifting fixture 1 and a fixing beam 30. The lifting fixture 1 is movably arranged on the safety beam 2. The lifting fixture 1 is used to clamp the cab 3 and drive the cab 3 to move. The fixing beam 30 is arranged on the cab 3. The fixing beam 30 has a connection state connected to the assembly mechanism, and the fixing beam 30 has a separation state separated from the assembly mechanism. Wherein, the assembly mechanism is located at the assembly position, and the assembly mechanism is used to perform assembly operations on the cab 3.

[0039] Applying the technical solution of this embodiment, a fixing beam 30 is arranged on the cab 3. When the cab 3 is assembled, the fixing beam 30 can connect the cab 3 and the assembly mechanism at the same time. When the cab 3 is moved to the assembly position by the lifting fixture 1, the relative position of the cab 3 and the assembly mechanism is fixed through the fixing beam 30, which can ensure that when the assembly mechanism performs assembly operations on the cab 3, the position of the cab 3 can be accurately recognized by the assembly mechanism, facilitating the assembly mechanism to perform precise assembly operations, thereby maintaining the stability of the cab 3 during the assembly process, avoiding the possible small displacement of the cab 3 in the traditional lifting method, and improving the assembly accuracy.

[0040] Specifically, as Figure 3 , Figure 4 shown, the fixed beam 30 includes a front beam body 300, a plurality of first connectors 310 and a plurality of second connectors provided on the front beam body 300. Along the extending direction of the front beam body 300, the plurality of first connectors 310 and the plurality of second connectors are arranged at a distance. The first connectors 310 are used to connect with the cab 3, and the second connectors are used to connect with the assembly mechanism. The fixed beam 30 bears and shares the weight of the cab 3 and the forces generated during the assembly process through the front beam body 300 to ensure the structural stability. By arranging the plurality of first connectors 310 and the second connectors at a certain distance along the extending direction of the front beam body 300, the connection between the cab 3 and the assembly mechanism is ensured to be more uniform and stable, avoiding local stress concentration that may be caused by single-point connection, improving the reliability of the connection and the stability of the cab 3, making the position of the cab 3 more stable during the assembly process, reducing the assembly error, improving the assembly quality and efficiency, and at the same time being able to better control the positioning of the cab 3 and reducing its displacement during the assembly process.

[0041] It should be noted that the second connectors are also arranged at a distance along the extending direction of the front beam body 300. The plurality of second connectors are connected to the assembly mechanism, which can ensure the stable connection between the assembly mechanism and the fixed beam 30. In an embodiment of the present application, the second connectors are of a telescopic type, realized by an internal spring or a pneumatic cylinder, so that the connectors can be telescoped within a certain range. When the assembly mechanism needs to operate with the cab, the telescopic second connectors can automatically adjust the length according to the contact points of the assembly mechanism to ensure the vertical contact between the assembly mechanism and the surface of the cab, reducing the assembly error caused by angle or distance mismatch.

[0042] In another embodiment of the present application, the second connectors have multi-directional adjustment capabilities, including universal joints. The universal joints can enable the second connectors to move freely in three-dimensional space, ensuring that no matter from which direction the assembly mechanism approaches the cab, the second connectors can quickly adjust to the optimal contact position, improving the flexibility and efficiency of the assembly.

[0043] Furthermore, at least one of the first connecting member 310 and the second connecting member is slidably disposed along the extending direction of the front beam body 300. By means of the sliding function of the first connecting member 310 or the second connecting member, fine adjustment can be made according to the size of the cab 3 and the position of the assembly mechanism, ensuring the accuracy and flexibility of the connection, improving the adaptability and precision of the assembly, and reducing the assembly difficulties caused by size mismatches. During the assembly process, when the position of the connecting member needs to be adjusted, the slidable connecting member enables the operator to easily manually or through auxiliary equipment adjust the position of the connecting member, reducing the operation time and labor intensity and improving the production efficiency. When the connecting member is worn or damaged during use, the operator does not have to disassemble the entire fixing system, but only needs to simply move or replace a specific connecting member to restore the normal operation of the system, reducing the maintenance cost and downtime.

[0044] Furthermore, at least one of the first connecting member 310 and the second connecting member has a locked state in which it is locked to the front beam body 300, and a released state in which it is slidable relative to the front beam body 300. Through the locking and releasing mechanism, the position of the first connecting member 310 or the second connecting member can be fixed when needed to ensure the stability of the connection, and the locked state is released when adjusting the position to achieve flexible adjustment, improving the flexibility and stability of the assembly, reducing the small displacements during the assembly process, and improving the assembly precision. At the same time, the locked state ensures the firm connection between the cab and the fixing system, can effectively prevent the cab from being displaced due to external forces, reduces the occurrence of assembly errors, and improves the assembly quality and safety of the product; while the released state allows the connecting member to slide along the front beam body 300 as needed, and can be quickly adjusted to the optimal position when facing different types of cabs 3 or assembly operations, improving the versatility and adaptability of the system.

[0045] Furthermore, as Figure 3 , Figure 4 shown, stoppers 320 are provided at both ends of the front beam body 300. By restricting the movement range of the front beam body 300 through the stoppers 320, accidental movement of the front beam body 300 during the assembly process can be prevented, ensuring the positioning accuracy of the cab during the assembly process and the safety of the system operation. This design not only enhances the structural stability and durability of the system, but also facilitates maintenance and adjustment, reduces excessive wear of components, extends the service life, thus significantly improving the overall performance and reliability of the cab fixing system, enhancing the stability of the cab 3 during the assembly process, and reducing the assembly errors caused by the movement of the front beam body 300.

[0046] Furthermore, the first connecting member 310 has a plurality of connecting segments 311. The connecting segments 311 are used to connect the cab 3. When the first connecting member 310 is connected to the cab 3, at least one connecting segment 311 is used to connect the bottom end of the cab 3, and at least one connecting segment 311 extends into the cab 3. By connecting the plurality of connecting segments 311 to the bottom end and the interior of the cab 3, the contact area of the connection is increased, and the stability and reliability of the connection are improved. At least one connecting segment 311 is used to connect the bottom end of the cab, and at least one connecting segment extends into the cab, reducing the displacement of the cab during the assembly process, making the position of the cab 3 more stable during the assembly process, reducing the displacement during the assembly process, and improving the assembly accuracy.

[0047] It should be noted that extending some of the connecting segments 311 into the cab can provide additional support to prevent the cab from tilting or falling due to unstable center of gravity during hoisting or assembly, ensuring the safety of the operators and reducing the potential safety risks during the production process. In an embodiment of the present application, the connecting segment 311 extending into the cab 3 and the connecting segment 311 connecting the bottom of the cab 3 can exert a clamping effect on the cab 3, preventing the fixed beam 30 from detaching from the cab 3 during the movement or assembly of the cab 3, causing damage to people and property.

[0048] In an embodiment of the present application, the connecting segment 311 is integrally formed with the front beam main body 300. The integrally formed connection method reduces potential structural weaknesses and improves the strength and stability of the overall structure. When bearing heavy loads or encountering strong vibrations, the integrally formed design can better maintain the connection between the connecting member and the front beam main body, avoiding the cab being fixed unstably or damaged due to the failure of the connection point. At the same time, the integral forming reduces the need for additional connecting components such as bolts, pins or welding materials, thereby simplifying the manufacturing process and reducing the material cost and labor cost during the manufacturing process.

[0049] Furthermore, the lifting jig 1 has a fixed position locked with the safety beam 2, and the lifting jig 1 has a release position movable relative to the safety beam 2. A guide groove 21 is provided on the safety beam 2. When the lifting jig 1 is in the fixed position, at least part of the lifting jig 1 extends into the guide groove 21. The locking design of the lifting jig 1 and the safety beam 2 ensures the stability during the hoisting of the cab 3, reduces the risk of accidental slipping during the operation, thereby improving the safety standards on the assembly line; the lifting jig 1 extending into the guide groove 21 provides accurate guidance and positioning, helping to precisely control the position of the cab during the hoisting process and avoiding minor offsets. At the same time, the locked state can effectively resist the vibrations on the production line, preventing the jig from loosening and causing the cab to shift, ensuring the smoothness and efficiency during the assembly process.

[0050] In this embodiment, the guiding groove 21 is set as a V-shaped groove along the extending direction of the safety beam 2. The geometric shape of the V-shaped groove can form a tight fit with the corresponding part of the lifting fixture 1, effectively guiding the precise movement of the lifting fixture thereon, ensuring more accurate positioning of the cab during the assembly process, and reducing the assembly errors caused by position deviation; the V-shaped groove increases the stability of the contact surface. Even when encountering vibration or slight displacement during the lifting process, the lifting fixture 1 is not easily slipped out of the guiding groove, improving the stability and safety of the entire system. At the same time, the inclined surfaces on both sides of the V-shaped groove have a self-positioning effect, that is, after the lifting fixture 1 enters the V-shaped groove, it will naturally adjust its position until it contacts the two sides of the groove, thus realizing automatic centering, simplifying the adjustment work of the operator, and improving the work efficiency.

[0051] Specifically, a plurality of clamping members are further provided on the safety beam 2. Along the extending direction of the safety beam 2, the plurality of clamping members are arranged at intervals. When the lifting fixture 1 is in a fixed position, the clamping members abut against at least a part of the lifting fixture 1 to clamp and fix the lifting fixture 1. By clamping and fixing the lifting fixture 1 through the plurality of clamping members, the stability of the cab 3 during the lifting and assembly processes is further enhanced, avoiding the displacement of the cab 3 caused by the loosening of the lifting fixture 1, significantly improving the stability of the cab 3 during the lifting and assembly processes, reducing the displacement and assembly errors, and improving the assembly efficiency and product quality. The arrangement of the plurality of clamping members ensures that the lifting fixture 1 can be evenly stressed when in a fixed position, effectively preventing the fixture from displacing or vibrating due to single-point stress, and enhancing the overall stability and reliability of the system.

[0052] In an embodiment of the present application, the clamping members are arranged at the four corners of the circumferential frame of the lifting fixture 1. The clamping members use air cylinders or electric cylinders to abut against and clamp the frame of the lifting fixture 1. The power output provided by the air cylinders or electric cylinders can be precisely controlled. This power-type clamping method can ensure the stability and uniformity of the clamping force, avoiding uneven force that may be brought by manual operation, thereby improving the stability of the entire system and the accuracy of cab positioning; at the same time, the fast response characteristics of the air cylinders or electric cylinders enable the clamping action to be completed quickly, not only shortening the assembly preparation time, but also improving the flexibility of the production line. Using air cylinders or electric cylinders as clamping members can also be integrated with the automated control system of the production line to realize the automation of the clamping operation, reducing manual intervention, improving the production efficiency and reducing the labor intensity of the operators, reflecting the overall intelligent effect of the system.

[0053] Further, as Figure 1 、 Figure 2As shown, the cab fixing system further includes a safety protection mechanism 4. The safety protection mechanism 4 is arranged on the lifting fixture 1. There are two safety protection mechanisms 4, and the two safety protection mechanisms 4 are respectively arranged on the opposite sides of the cab 3. The safety protection mechanism 4 has a protection position for preventing the cab 3 from falling, and the safety protection mechanism 4 has an avoidance position for avoiding the cab 3. When the safety protection mechanism 4 is in the protection position, at least part of the safety protection mechanism 4 extends into the cab 3. When the safety protection mechanism 4 is in the avoidance position, the safety protection mechanism 4 is located outside the cab 3. By arranging the safety protection mechanism 4 on both sides of the cab 3, additional safety protection can be provided during the lifting and assembly process to prevent the cab 3 from accidentally falling. At the same time, it can move flexibly when avoidance is needed without affecting the assembly operation, significantly improving the safety of the cab 3 during the lifting and assembly process, reducing the occurrence of accidents, and improving the operation efficiency. When in the protection position, part of the structure of the safety protection mechanism 4 extends into the cab, forming a physical barrier, effectively preventing the cab from accidentally falling during the lifting process, and significantly improving the safety of the assembly operation. At the same time, the safety protection mechanism 4 can be moved to the avoidance position, located outside the cab, without hindering the progress of the assembly operation, enabling the operator or mechanical equipment to approach the cab without obstacles for necessary assembly and adjustment work.

[0054] In an exemplary embodiment of the present application, the safety protection mechanism 4 is an arm arranged on both sides of the cab 3 window. The arm directly acts on both sides of the cab window, forming a stable physical support, effectively preventing the cab from accidentally tipping over or falling during the lifting or assembly process, and significantly improving the operation safety. When the arm is in the protection position, the two arms extend into the side windows of the cab 3 but do not contact the cab 3. When the cab 3 loses weight or accidentally detaches from the lifting fixture 1, the arm can provide support on both sides of the cab 3 to prevent the cab 3 from falling onto the production line and causing damage to people and property.

[0055] Further, as Figure 1 、 Figure 2As shown, the cab fixing system further includes an auxiliary fixing mechanism 5. The auxiliary fixing mechanism 5 is arranged on the lifting fixture 1. There are two auxiliary fixing mechanisms 5, and the two auxiliary fixing mechanisms 5 are respectively arranged on the opposite sides of the cab 3. The auxiliary fixing mechanism 5 abuts against at least one of the cab 3 and the safety protection mechanism 4. By arranging the auxiliary fixing mechanism 5 on both sides of the cab 3, it can abut against at least one of the cab 3 and the safety protection mechanism 4, further enhancing the stability of the cab 3 during the hoisting and assembly processes, avoiding the displacement of the cab 3 caused by external factors, significantly improving the stability of the cab 3 during the hoisting and assembly processes, and reducing the displacement and assembly error. By abutting against the cab or the safety protection mechanism 4, the auxiliary fixing mechanism 5 provides additional fixing points, enhancing the stability of the entire system and effectively preventing the shaking and displacement of the cab during the assembly process. The position adjustment and fixation of the auxiliary fixing mechanism 5 contribute to the precise alignment of the cab with the assembly mechanism, reducing the positioning error that may be caused by the single-point force of the lifting fixture and improving the assembly accuracy and efficiency.

[0056] In an embodiment of the present application, a lifting component is arranged on the assembly mechanism. The lifting component is used to connect with the second connecting piece to fix the relative position between the cab and the assembly mechanism. The precise connection between the lifting component and the second connecting piece can ensure the position fixation of the cab during the assembly process, reduce the assembly deviation caused by displacement, and improve the assembly accuracy; by automatically completing the connection with the second connecting piece through the lifting component, the adjustment process of the operator is simplified, the requirements for the operator's skills are reduced, and the operation efficiency is improved; at the same time, the automated operation of the lifting component is integrated with the overall control system, improving the automation level of the assembly line, reducing manual intervention, and facilitating the realization of intelligent production.

[0057] Adopting the cab fixing system in the above-mentioned embodiment, through the setting of the fixing beam 30, the hoisting fixture 1, the safety protection mechanism 4, the auxiliary fixing mechanism 5, and the lifting component of the assembling mechanism, the accurate positioning, stable clamping and safety protection of the cab 3 during the assembling process are realized. Among them, the slidable setting of the first connecting piece 310 and the second connecting piece on the fixing beam 30 enables the system to adapt to cabs 3 of different sizes and types, enhancing the flexibility and applicability of the system; the locking and releasing mechanism of the hoisting fixture 1 and the safety beam 2 ensures the safety of the cab 3 during movement and assembly; the dual fixing and protection functions of the safety protection mechanism 4 and the auxiliary fixing mechanism 5 effectively prevent the accidental dropping or displacement and shaking of the cab 3 during the assembling process, guaranteeing the safety of the operators and the assembling quality of the cab 3. The lifting component of the assembling mechanism realizes the relative position fixing between the cab 3 and the assembling mechanism through precise connection with the second connecting piece, greatly improving the assembling efficiency and precision. The above-mentioned components are connected through integration with the control system, which not only solves the problems of inaccurate positioning, poor stability and high safety risks existing in the prior art during the cab assembling process, but also provides reliable technical support for the automated, intelligent and high-precision assembling of the cab 3, with remarkable technical and economic benefits.

[0058] As can be seen from the above description, the cab fixing system in this embodiment has the following beneficial effects: Through the combined use of the fixing beam 30 and the auxiliary fixing mechanism 5, the displacement of the cab 3 during the assembling process is effectively controlled, providing a stable working environment for the assembling mechanism to identify studs and accurately tighten nut gaskets, thus significantly improving the assembling precision. Reducing the shaking of the cab 3 during the assembling process can not only improve the assembling precision, but also reduce the assembly failures and manual interventions caused by the shaking of the cab 3, thereby shortening the beat time of a single assembly and improving the efficiency of the production line.
