Description

Technical Field

[0001] The present invention relates to the field of vehicle body production and transportation, and in particular to a vehicle body floor assembly conveying line. Background Art

[0002] Underbody assembly conveyor lines are crucial equipment in the automotive manufacturing process for efficiently and accurately transporting vehicle frames and their components. These lines typically integrate a variety of automation technologies and equipment to ensure smooth production at every step. Underbody assembly lines transport vehicle frames to various assembly stations, where they are then continuously loaded with components by manual or mechanical equipment.

[0003] In the transportation of the body floor assembly, the commonly used transportation method is to use a plate chain conveyor line for transmission. The body positioning mechanism is installed on the plate chain conveyor belt, and then the body floor assembly is fixed above the body positioning mechanism. The conveying capacity of the plate chain conveyor line is used to transport the body positioning mechanism and the body floor assembly together to the corresponding assembly station.

[0004] During the simultaneous assembly and conveyance of the vehicle body underbody assembly, as the various components of the vehicle body underbody assembly are added, its own weight will continue to increase, causing the vehicle body positioning mechanism to exert increasing local pressure on the plate chain conveyor belt. This will increase the pressure and friction on the local plate chain conveyor belt, which can easily cause severe wear of the local plate chain. If the local plate chain is subjected to excessive pressure for a long time, it can also easily cause the plate chain to bend and deform, which will cause damage to the plate chain. In addition, during the process of adding components to the vehicle body underbody assembly, the weight of each part of the vehicle body underbody assembly is not the same, which will cause the pressure difference caused by the vehicle body positioning mechanism on the plate chain conveyor belt to increase, resulting in uneven force on the plate chain conveyor belt, making the plate chain conveyor belt more prone to wear problems. To this end, we propose a vehicle body underbody assembly conveyor line. Summary of the Invention

[0014] Preferably, a scraper block is fixedly provided on one side of the bottom of the two walking wheel mounting frames at the forward end of the base plate body, and a flexible wear-resistant pad is fixedly provided on the bottom of the scraper block.

[0015] The present invention has the following beneficial effects: The present invention facilitates the adjustment of the position of the support frame. By adjusting the position of the support frame, it is suitable for installing different vehicle frames, thereby facilitating the transportation of different vehicle frames. The pressure of the vehicle frame is used to cause the positioning plate to generate friction on the sliding plate to clamp the sliding plate, so that the position of the sliding plate remains stationary. The fixing of the sliding plate is simple and convenient. During the manual assembly of the vehicle frame, the sliding plate is not easily moved laterally. This not only reduces the pressure of the sliding plate on the linear guide rail, making the linear guide rail less susceptible to wear and tear, but also avoids the problem of the subsequent assembly being affected by the change in the position of the vehicle frame on the base plate body due to external force during the assembly of the vehicle frame, thereby improving the transportation accuracy of the conveyor line.

[0016] When the vehicle frame is fixed on the support frame, the vehicle frame generates pressure on the base plate body through the structure of the sliding plate and the linear guide rail, so that the walking wheels are pressed on the guide seat. During this process, the walking wheels generate a reaction force on the sliding sleeve through the connecting shaft. Since the hydraulic component is fixedly installed on the base plate body, the output end of the hydraulic component pulls the sliding sleeve, so the overall structure of the walking support mechanism supports the base plate body, thereby supporting the vehicle frame.

[0017] 3. In the present invention, the conveyor belt pushes the card plate through the drive plate, driving the bottom plate body to move, so that the running wheels move on the guide seat. Therefore, the running support mechanism plays a supporting role on the vehicle body positioning mechanism and the frame, greatly reducing the supporting force of the conveyor belt on the vehicle body positioning mechanism and the frame, so that the pressure and friction on the conveyor belt are greatly reduced. During the long-term operation of the conveyor belt, it can not only reduce the local wear of the conveyor belt, but also avoid the problem of local deformation of the conveyor belt due to excessive force. In addition, the conveyor belt uses the structure of the drive plate and the card plate to form a traction and conveying effect on the vehicle body positioning mechanism and the frame. With the assistance of the running wheels, the conveyor belt is more convenient for conveying the vehicle body positioning mechanism and the frame, reducing the energy consumption of the device. Therefore, this design facilitates the protection of the conveyor belt and increases the service life of the conveyor belt.

[0018] 4. In the present invention, the connecting shaft is arranged inside the sleeve. When the positioning plate and the sliding plate are in conflict, the support force of the connecting shaft on the sleeve will change after the height of the sleeve is adjusted using the hydraulic assembly. At this time, the pressure of the sliding plate on the positioning plate changes, causing the pressure of the positioning plate on the conveyor belt to change. By using the hydraulic assembly to change the height of the sleeve, the pressure on the conveyor belt can be adjusted. During the continuous assembly of the frame, the weight of the frame will continue to increase, causing the pressure of the sliding plate on the positioning plate to continue to increase, resulting in a continuous increase in the force on the conveyor belt. At this time, by using the hydraulic assembly to lower the height of the sleeve, the pressure on the conveyor belt can be reduced, which plays a role in preventing the conveyor belt from being worn and deformed due to the increasing force. Since the weight of different positions of the frame is different, by using the hydraulic assembly to adjust the height of the sleeve, the pressure values of multiple sliding plates on the positioning plate can be made close, avoiding the problem of the conveyor belt being easily damaged due to uneven force.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0023] See also Figure 1 - Figure 10As shown, a vehicle body floor assembly conveying line includes a circulating conveying mechanism 1, a vehicle body positioning mechanism 2 arranged above the circulating conveying mechanism 1, and a walking support mechanism 3 provided at the four corners of the vehicle body positioning mechanism 2; The loop conveying mechanism 1 includes a guide base 101, a conveyor belt 102 movably mounted inside the guide base 101, and a drive plate 103 and a positioning plate 104 fixedly mounted above the conveyor belt 102. In this mechanism, the conveyor belt 102 is a plate-chain belt structure that provides power for the movement of the vehicle body positioning mechanism 2. The traveling support mechanism 3 moves on the guide base 101 and supports the vehicle body positioning mechanism 2. The conveyor belt 102 circulates on the guide base 101, which supports the conveyor belt 102. The loop conveying mechanism 1 also includes a drive device that drives the conveyor belt 102.

[0024] The vehicle body positioning mechanism 2 includes a base plate body 201, a linear guide rail 202 movably arranged in the middle above the base plate body 201, a sliding plate 203 arranged above the slide of the linear guide rail 202, a support frame 204 fixedly installed above the sliding plate 203, and a card plate 205 fixedly installed at the bottom of the base plate body 201. The support frame 204 is used to support the frame. The card plate 205 is adapted to the drive plate 103 and contacts the drive plate 103. The upper end of the positioning plate 104 passes through the base plate body 201 and is used to support and limit the support frame 204. During the transportation of the frame, the card plate 205 is stuck on the inner side of the drive plate 103.

[0025] When the device is working, the linear guide rail 202 is used to change the position of the sliding plate 203 to adjust the position of the support frame 204, so that the device can adjust the position of each support frame 204 accordingly, so that the support frame 204 can support frames of different sizes. When the support frame 204 fixes the frame, the frame is installed on the support frame 204, and the frame generates pressure on the sliding plate 203 through the support frame 204, so that the sliding plate 203 is pressed on the positioning plate 104. At this time, the positioning plate 104 supports the frame, and the positioning plate 104 also generates pressure on the conveyor belt 102 at the bottom.

[0026] During the operation of the conveyor belt 102, the clamping plate 205 engages with the driving plate 103 to drive the vehicle body positioning mechanism 2 to move. The driving plate 103 only acts as a traction force on the vehicle body positioning mechanism 2 and the vehicle frame, but does not bear the pressure of the vehicle body positioning mechanism 2 and the vehicle frame. The positioning plate 104 is used to bear the gravity of the vehicle body positioning mechanism 2 and the vehicle frame, thereby reducing the load on the chain plate corresponding to the bottom of the driving plate 103 and the bottom of the positioning plate 104. This ensures that the chain plates corresponding to the bottom of the driving plate 103 and the positioning plate 104 are not subjected to forces in different directions, thereby reducing the wear of the chain plates corresponding to the bottom of the driving plate 103 and the positioning plate 104.

[0027] Based on this device, the position of the support frame 204 is easily adjusted. By adjusting the position of the support frame 204, it is suitable for installing different frames, thereby facilitating the transportation of different frames. The pressure of the frame is used to make the positioning plate 104 generate friction on the sliding plate 203 to clamp the sliding plate 203, so that the position of the sliding plate 203 remains stationary. The fixing of the position of the sliding plate 203 is simple and convenient. During the manual assembly of the frame, the sliding plate 203 is not easily moved laterally. This not only reduces the pressure of the sliding plate 203 on the linear guide rail 202, making the linear guide rail 202 less susceptible to wear and tear, but also avoids the problem of the subsequent assembly being affected by the change in the position of the frame on the base plate body 201 due to external force, making the transportation accuracy of this conveyor line higher.

[0028] The walking support mechanism 3 includes a limit frame 301 fixedly installed above the corner of the base plate body 201, a sleeve 302 movably installed on one side of the inner part of the limit frame 301, a hydraulic component 303 fixedly installed above the corner of the base plate body 201, a connecting shaft 304 arranged at the lower inside of the sleeve 302, the connecting shaft 304 elastically supports the sleeve 302, and a walking wheel 305 arranged below the corner of the base plate body 201, the hydraulic component 303 is used to adjust the height of the sleeve 302 and to pull the sleeve 302, the bottom end of the connecting shaft 304 passes through the base plate body 201 and is fixedly connected to the mounting frame of the walking wheel 305, the wheel body of each walking wheel 305 rolls on the guide seat 101, and the upper end of the positioning plate 104 passes through the base plate body 201 and contacts the sliding plate 203.

[0029] Based on this device, when the positioning plate 104 bears the weight of the vehicle body positioning mechanism 2 and the vehicle frame, the hydraulic assembly 303 pulls the sleeve 302, and the connecting shaft 304 elastically supports the sleeve 302, so that the running wheels 305 and the connecting shaft 304, through the structure of the sleeve 302 and the hydraulic assembly 303, also support the vehicle body positioning mechanism 2 and the vehicle frame. Therefore, the running support mechanism 3 is used to share the weight borne by the positioning plate 104, and the rolling action of the running wheels 305 can greatly reduce the friction experienced by the device during movement, making it easier for the drive plate 103 to pull the device. Therefore, this device can further reduce wear on the corresponding chain plates at the bottom of the drive plate 103 and the positioning plate 104.

[0030] Due to the uneven weight distribution of various parts of the frame, the pressure exerted on each support frame 204 is different, resulting in different pressures on each positioning plate 104, and the friction force on the corresponding chain plate at the bottom of each positioning plate 104 is also different. During long-term operation, the degree of friction of the chain plate will also vary greatly, which can easily cause some chain plates to be severely worn, affecting the smooth operation of the conveyor belt 102. In order to solve this problem, the device shares the weight of the positioning plate 104 by changing the elastic support force of the connecting shaft 304 on the sliding sleeve 302. When the elastic support force of the connecting shaft 304 on the sliding sleeve 302 is changed, the running wheel 305 presses against the guide seat 101, and during this process, the running wheel 305 generates a reaction force on the sliding sleeve 302 through the connecting shaft 304. Since the hydraulic assembly 303 is fixedly mounted on the base plate body 201, the output end of the hydraulic assembly 303 pulls the sliding sleeve 302. Therefore, when the hydraulic assembly 303 lowers the height of the sliding sleeve 302, the elastic support force of the connecting shaft 304 on the sliding sleeve 302 is strengthened, and the running wheel 305 exerts a greater support force on the vehicle body positioning mechanism 2 and the vehicle frame through the connecting shaft 304. Therefore, by adjusting the corresponding hydraulic assembly 303 and lowering the height of the corresponding sliding sleeve 302, the force applied to the positioning plate 104 can be reduced, thereby reducing the friction of the chain plate at the bottom of the positioning plate 104, thereby reducing the wear of the chain plate.

[0031] Therefore, in this device, the conveyor belt 102 pushes the card plate 205 through the drive plate 103, driving the base plate body 201 to move, causing the running wheels 305 to move on the guide seat 101. Therefore, the running support mechanism 3 plays a supporting role on the body positioning mechanism 2 and the frame, greatly reducing the supporting force of the conveyor belt 102 on the body positioning mechanism 2 and the frame, and greatly reducing the pressure and friction on the conveyor belt 102. During the long-term operation of the conveyor belt 102, not only can the local wear of the conveyor belt 102 be reduced, but also the problem of local deformation of the conveyor belt 102 due to excessive force is avoided. In addition, the conveyor belt 102 uses the structure of the drive plate 103 and the card plate 205 to form a traction conveying effect on the body positioning mechanism 2 and the frame. With the assistance of the running wheels 305, the conveyor belt 102 is more convenient for conveying the body positioning mechanism 2 and the frame, reducing the energy consumption of the device. Therefore, this design facilitates the protection of the conveyor belt 102 and increases the service life of the conveyor belt 102.

[0032] When the device is working, the connecting shaft 304 is arranged inside the sleeve 302. When the positioning plate 104 and the sliding plate 203 conflict with each other, the height of the sleeve 302 is adjusted by using the hydraulic component 303, so that the supporting force of the connecting shaft 304 on the sleeve 302 is changed accordingly, and the pressure of the sliding plate 203 on the positioning plate 104 is changed accordingly, which plays a role in changing the pressure generated by the positioning plate 104 on the conveyor belt 102, making it easy to adjust the force of the plate chain on the conveyor belt 102 corresponding to each positioning plate 104, so that the force is balanced, thereby improving the working stability and service life of the conveyor belt 102.

[0033] Therefore, this device can adjust the pressure on the conveyor belt 102 by changing the height of the sliding sleeve 302 using the hydraulic component 303. During the continuous assembly of the frame, the weight of the frame will continue to increase, causing the pressure of the sliding plate 203 on the positioning plate 104 to continue to increase, resulting in a continuous increase in the force on the conveyor belt 102. At this time, by using the hydraulic component 303 to lower the height of the sliding sleeve 302, the pressure on the conveyor belt 102 can be reduced, which plays a role in preventing the conveyor belt 102 from being worn and deformed due to the increasing force. Since the weight of different positions on the frame is different, by using the hydraulic component 303 to adjust the height of the sliding sleeve 302, the pressure values of multiple sliding plates 203 on the positioning plate 104 can be close, avoiding the problem of the conveyor belt 102 being easily damaged due to uneven force.

[0034] Among them, through holes 4 are opened at the four corners of the base plate body 201, the connecting shaft 304 and the through holes 4 correspond one to one, the connecting shaft 304 slides inside the through holes 4, the hydraulic component 303 is located on the other side of the limit frame 301, and a guide member 5 compatible with the limit frame 301 is fixedly installed above the sliding sleeve 302. The guide member 5 slides inside the limit frame 301, and the output end of the hydraulic component 303 is fixedly connected to the upper side of the guide member 5.

[0035] In this device, the provision of the guide member 5 facilitates the hydraulic assembly 303 in adjusting the position of the sliding sleeve 302. The guide member 5 slides within the limiting frame 301. When the hydraulic assembly 303 pulls or pushes the guide member 5, the sliding sleeve 302 always moves vertically within the limiting frame 301. This structure improves the overall stability of the walking support mechanism 3 during operation.

[0036] Among them, the inner top of the sliding sleeve 302 is fixedly connected with the first spring 6 and the limiting rod 7, the limiting rod 7 is located inside the first spring 6, the bottom of the first spring 6 and the top of the connecting shaft 304 are fixedly connected, and a limiting hole 8 is opened in the middle of the top of the connecting shaft 304, and the limiting rod 7 is movably set inside the limiting hole 8.

[0037] Based on this device, the first spring 6 and the connecting shaft 304 are arranged inside the sliding sleeve 302. During the transportation of the frame, the first spring 6 is always in a compressed state. The first spring 6 bears gravity. At the same time, through the elasticity of the first spring 6, it plays a buffering role when the frame is erected on the support frame 204, avoiding impact on the positioning plate 104 and the plate chain at the bottom of the positioning plate 104, protecting the conveyor belt 102, and improving the stability of the transportation of the frame during transportation, preventing vibrations generated during transportation from causing wear on the conveyor belt 102. The limiting rod 7 is used to limit the first spring 6 to prevent lateral deformation of the first spring 6 during compression.

[0038] Among them, two slide grooves 9 are symmetrically opened above the bottom plate body 201, and a linear guide rail 202 is arranged inside each slide groove 9. Guide blocks 10 are fixedly installed on both sides of the slide groove 9, and a limit strip 11 is fixedly set above each guide block 10. Limit openings 12 corresponding to the limit strips 11 are opened on both sides of the bottom of the sliding plate 203, and the groove walls of the limit strips 11 and the corresponding limit openings 12 are fitted together. A rectangular opening 13 that passes through the bottom plate body 201 is opened inside each guide block 10, and the rectangular opening 13 corresponds to the limit opening 12 one by one. The rectangular opening 13 is located below the corresponding limit opening 12, and a positioning plate 104 is arranged inside each rectangular opening 13.

[0039] In this device, when the sliding plate 203 and the positioning plate 104 come into conflict, the guide block 10 also supports the sliding plate 203, thereby maintaining the stability of the sliding plate 203 and reducing the pressure exerted by the sliding plate 203 on the positioning plate 104. The limiting strip 11 and the limiting opening 12 limit the sliding plate 203 and, in conjunction with the guide block 10, prevent the sliding plate 203 from deflecting due to excessive force.

[0040] Among them, a friction plate 14 is fixedly installed at the bottom of each limit opening 12, and pressure sensors 15 are fixedly installed inside both ends of the sliding plate 203. The pressure sensors 15 and the friction plates 14 correspond one to one, and the pressure sensors 15 are located above the corresponding friction plates 14.

[0041] This device, through the friction plate 14 and the positioning plate 104, creates a greater frictional force between them, thus providing a better anti-slip effect on the sliding plate 203. The pressure sensor 15 is configured to detect the pressure between the friction plate 14 and the positioning plate 104. During the frame assembly process, by detecting the pressure between the friction plate 14 and the positioning plate 104, the height of the sliding sleeve 302 can be adjusted using the hydraulic assembly 303, thereby stabilizing the pressure between the friction plate 14 and the positioning plate 104.

[0042] Among them, a limit seat 16 is fixedly installed above the slide of the linear guide rail 202, a circular groove 19 is opened inside the upper part of the limit seat 16, a limit groove 17 is opened in the middle of the bottom of the sliding plate 203, a slip ring 18 is set in the middle of the inner part of the limit groove 17, and the slip ring 18 is movably set inside the circular groove 19, and the top wall of the limit groove 17 is fixedly connected to the second spring 25, and the bottom end of the second spring 25 is fixedly connected to the bottom of the circular groove 19.

[0043] Based on this device, the second spring 25 connects the sliding plate 203 and the limit seat 16 respectively, and supports the sliding plate 203. When the friction plate 14 and the positioning plate 104 come into contact, the bottom of the sliding plate 203 does not contact the inner bottom wall of the limit seat 16, so that the sliding plate 203 does not exert pressure on the slide of the linear guide 202 through the limit seat 16, thereby protecting the linear guide 202 and preventing it from being damaged by excessive force. The limit seat 16 is always located below the inner part of the limit slot 17. During the movement of the slide of the linear guide 202, the structure of the limit seat 16 drives the sliding plate 203 to move.

[0044] A first air hole 20 is provided at the lower side of the connecting shaft 304 , and the first air hole 20 is communicated with the limiting hole 8 . A second air hole 21 is provided at the upper side of the sliding sleeve 302 .

[0045] Based on this device, the first air hole 20 is convenient for balancing the internal and external pressure difference of the limiting hole 8 , and the setting of the second air hole 21 is convenient for balancing the internal and external pressure difference of the sliding sleeve 302 .

[0046] An anti-slip pad 22 is fixedly installed above the positioning plate 104 .

[0047] Based on this device, the anti-skid pad 22 and the friction plate 14 are in contact, and both have higher anti-skid properties.

[0048] Among them, a scraper block 23 is fixedly provided on one side of the bottom of the two walking wheel 305 mounting frames at the forward end of the base plate body 201, and a flexible wear-resistant pad 24 is fixedly provided on the bottom of the scraper block 23.
