Abstract
Description
Technical Field
[0001] This utility model relates to the field of trailer processing technology, specifically to a trailer panel clamping device for trailer processing. Background Technology
[0002] A trailer is a vehicle towed by a truck but without its own power drive. It consists of one truck (truck, tractor, or forklift) and one or more trailers. The truck and tractor are the driving sections of the truck train, called the tractor unit, and the driven sections towed by the tractor unit are called trailers. Trailers are classified into full trailers and semi trailers according to the way they are connected to the tractor unit. A full trailer is towed by the tractor unit and bears all of its weight. A semi trailer is towed by the tractor unit and bears part of its weight. The body panel is an important component of a semi trailer. During its manufacturing process, the body panel is pressed to make its surface smoother.
[0003] However, most existing panel clamping devices can only fix the panel in one direction. Since the other direction of the panel is not fixed, the panel may shift in position, which makes the surface of the panel prone to uneven stress during clamping, thus affecting the quality of the finished panel. Utility Model Content
[0004] In view of this, the present invention provides a trailer panel clamping device that can clamp and fix the panel in both longitudinal and transverse directions, prevent the panel from shifting position, make the surface of the panel more uniform during clamping, and improve the quality of the finished panel.
[0005] To solve the above-mentioned technical problems, this utility model provides a trailer panel clamping device, including a base, a worktable on the upper part of the base, a clamping mechanism on the upper part of the worktable, and an all-around clamping mechanism inside the worktable. The all-around clamping mechanism includes a longitudinal clamping component and a transverse clamping component. The longitudinal clamping component is slidably disposed on both sides of the upper surface of the worktable and includes a clamping part and an L-shaped clamping plate. The clamping part is used to drive the L-shaped clamping plate to move closer together in the longitudinal direction to clamp and fix the trailer panel. The transverse clamping component is disposed on one side wall of the worktable and is used to drive the L-shaped clamping plate to move laterally. The L-shaped clamps are brought closer together to clamp and fix the panel. The worker places the panel to be pressed on the center of the workbench surface, and then adjusts the lateral position of the L-shaped clamps using the lateral clamping components, so that the L-shaped clamps fit against the lateral side walls of the panel. Then, the clamping components move the L-shaped clamps closer together in the longitudinal direction, so that the L-shaped clamps clamp and fix the panel in the longitudinal direction. Finally, the pressing mechanism presses and fixes the panel, so that the L-shaped clamps can clamp and fix the panel in both the longitudinal and lateral directions, preventing the panel from shifting position, making the surface stress of the panel more uniform during pressing, and improving the quality of the finished panel.
[0006] The clamping component includes two fixed frames that are slidably mounted on both sides of the upper surface of the workbench. Two movable blocks are slidably mounted on both sides inside each fixed frame. A bidirectional lead screw is rotatably mounted inside the fixed frame. The two movable blocks are threaded onto the threaded surfaces on both sides of the bidirectional lead screw. A handle is provided at one end of the fixed frame, with the end of the handle penetrating through the side wall of the fixed frame and connected to the end of the bidirectional lead screw. A connecting block is provided on one side of each movable block. A through groove adapted to the connecting block is opened on one side wall of the fixed frame. The connecting block is slidably mounted in the through groove of the side wall of the fixed frame. One side of the L-shaped clamping plate is fixed to the end of the connecting block. After the operator moves the L-shaped clamping plate against the lateral side wall of the panel using the transverse clamping assembly, they rotate the handle, causing the two movable blocks to move synchronously through the connecting block, thus bringing the two L-shaped clamping plates closer together longitudinally to clamp and fix the panel.
[0007] The lateral clamping assembly includes two drive slots located on both sides of the worktable. Each drive slot has a movable column slidably mounted therein, and connecting columns are located on both sides of the upper part of the movable column. The worktable surface has a sliding groove adapted to the connecting column, and the connecting column is slidably mounted in the sliding groove. The upper end of the connecting column is fixed to the lower wall of the fixed frame. The lateral clamping assembly also includes a drive frame located on the side wall of the worktable. The drive frame contains a drive component, which is used to drive the two movable columns to move closer to each other. When the panel is placed on the upper surface of the worktable, the drive component drives the two movable columns to move closer to each other. The movable columns drive the upper connecting columns to move synchronously, and the connecting columns drive the upper fixed frame to move. When the two movable columns move closer to each other, they drive the two upper fixed frames to move closer to each other synchronously, so that the L-shaped clamping plate on the side wall of the fixed frame can clamp the fixed panel laterally.
[0008] The driving component includes a gear rotatably mounted at the center of the drive frame. Guide rods are provided on both the upper and lower sides of the drive frame, and rack plates are slidably mounted on the surface of the guide rods. The two rack plates are respectively meshed and connected to the upper and lower sides of the gear. A fixed post is provided on one side wall of each rack plate. A connecting groove adapted to the fixed post is opened on the inner side wall of the drive frame, and the connecting groove is connected to the drive groove. The fixed post is slidably mounted in the connecting groove, and the end of the fixed post is fixed to one side wall of the movable post. A rotating component is provided at the center of the outer wall of the drive frame. The rotating component is used to drive the gear to rotate. The operator drives the gear to rotate by rotating the component, so that the fixed posts fixed on the side walls of the two rack plates move closer to each other. When the fixed posts move closer to each other, they drive the movable posts to move synchronously, so that the two movable posts move closer to each other.
[0009] The rotating assembly includes a limiting plate located at the center of the outer wall of the drive frame and corresponding to the end of the gear. A rotating shaft is rotatably mounted at the center of the surface of the limiting plate, with one end of the rotating shaft passing through the center of the limiting plate and connected to the center of the gear end. A fixing block is mounted at the other end of the rotating shaft, and a limiting component is mounted on the surface of the fixing block. The limiting component is used to limit and fix the gear. When the operator rotates the fixing block, the fixing block drives the rotating shaft to rotate, causing the rotating shaft to drive the gear to rotate. After the L-shaped clamping plate has finished laterally clamping the box plate, the limiting component limits and fixes the fixing block, preventing the fixing block from rotating. The gear and rotating shaft are also limited and fixed along with the fixing block, preventing the gear from rotating uncontrollably and improving the stability of the clamping process.
[0010] The limiting component includes a threaded hole at the end of the fixed block. A screw is threaded into the threaded hole at the end of the fixed block, and a rotating block is provided at one end of the screw. After the gear rotates, the operator holds the rotating block and rotates it. The rotating block drives the screw to rotate. At this time, the rotating block drives the screw to rotate around its own center axis. Since the screw is threaded into the threaded hole of the fixed block, the screw moves closer to the surface of the limiting plate while rotating, so that the end of the screw presses against the surface of the limiting plate. The friction force is increased by the screw pressing against the limiting plate to fix it, thereby limiting and fixing the fixed block.
[0011] A fixing rod is set at the center of the end of the rotating block. A bearing is installed on the surface of the fixing rod, and the fixing rod is fixed to the inner ring of the bearing. A sleeve is fixed to the outer ring of the bearing. When the operator needs to rotate the gear again, the rotating block is rotated in the opposite direction to make the end of the screw disengage from the surface of the limiting plate. Then, the sleeve is held and rotated. With the cooperation of the bearing, the fixing rod and the screw will not rotate around their own center, but will follow the fixing plate and rotate around the center of the rotation axis to drive the gear to rotate, making the operation more convenient.
[0012] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:
[0013] 1. When using this utility model, the worker places the panel to be pressed on the center of the workbench surface. Then, the L-shaped clamping plate is adjusted in the lateral direction by the lateral clamping component, so that the L-shaped clamping plate is attached to the lateral side walls of the panel. Then, the clamping component drives the L-shaped clamping plates to move closer to each other in the longitudinal direction, so that the L-shaped clamping plates clamp and fix the panel in the longitudinal direction. Finally, the pressing mechanism is used to press and fix the panel, so that the L-shaped clamping plate can clamp and fix the panel in both the longitudinal and lateral directions, preventing the panel from shifting position, making the surface force of the panel more uniform during pressing, and improving the quality of the finished panel.
[0014] 2. When using this utility model, the worker uses the transverse clamping component to drive the L-shaped clamping plate to adhere to the transverse side wall of the box panel, and then rotates the handle so that the two movable blocks drive the L-shaped clamping plate to move synchronously through the connecting block, so that the two L-shaped clamping plates move closer to each other in the longitudinal direction to clamp and fix the box panel.
[0015] 3. When this utility model is used, after the panel is placed on the surface of the workbench, the driving component drives the two movable columns to move closer to each other. The movable columns drive the upper connecting column to move synchronously, and the connecting column drives the upper fixed frame to move. When the two movable columns move closer to each other, they will drive the two upper fixed frames to move closer to each other synchronously, so that the L-shaped clamping plate on the side wall of the fixed frame can clamp the fixed panel from the horizontal direction.
[0016] 4. When using this utility model, the operator drives the gear to rotate by rotating the component, so that the fixed columns fixed on the side walls of the two rack plates move closer to each other. When the fixed columns move closer to each other, they drive the movable columns to move synchronously, so that the two movable columns move closer to each other. Attached Figure Description

Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-7 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.
[0026] According to one embodiment of the present invention, such as Figure 1 , Figure 2 , Figure 3 and Figure 6As shown: This embodiment provides a trailer panel clamping device for processing trailers, including a base 100, a worktable 200 on the upper part of the base 100, a clamping mechanism 300 on the upper part of the worktable 200, and an all-around clamping mechanism inside the worktable 200. The all-around clamping mechanism includes a longitudinal clamping component 500 and a transverse clamping component 600. The longitudinal clamping component 500 is slidably disposed on both sides of the upper surface of the worktable 200, and includes a clamping part and an L-shaped clamping plate 700. The clamping part is used to drive the L-shaped clamping plate 700 to move closer together in the longitudinal direction to clamp and fix the trailer panel. The transverse clamping component 600 is disposed on one side wall of the worktable 200, and is used to drive the L-shaped clamping plate 700 to move closer together in the longitudinal direction to clamp and fix the trailer panel. The clamping plates 700 move closer together in the lateral direction to clamp and fix the panel. The operator places the panel to be pressed on the center of the upper surface of the workbench 200. Then, the lateral clamping component 600 adjusts the lateral position of the L-shaped clamping plates 700 so that the L-shaped clamping plates 700 fit against the lateral side walls of the panel. Then, the clamping component moves the L-shaped clamping plates 700 closer together in the longitudinal direction so that the L-shaped clamping plates 700 clamp and fix the panel in the longitudinal direction. Finally, the pressing mechanism 300 presses and fixes the panel so that the L-shaped clamping plates 700 can clamp and fix the panel in both the longitudinal and lateral directions, preventing the panel from shifting position, making the surface force of the panel more uniform during pressing, and improving the quality of the finished panel.
[0027] Specifically, the clamping component includes two fixed frames 501 slidably disposed on both sides of the upper surface of the worktable 200. Two movable blocks 502 are slidably disposed on both sides inside each fixed frame 501. A bidirectional lead screw 503 is rotatably mounted inside the fixed frame 501. The two movable blocks 502 are threadedly connected to the threaded surfaces on both sides of the bidirectional lead screw 503. A handle 504 is provided at one end of the fixed frame 501, with the end of the handle 504 penetrating through the side wall of the fixed frame 501 and connected to the end of the bidirectional lead screw 503. A connecting block 505 is provided on one side of each movable block 502. A through groove adapted to the connecting block 505 is formed on one side wall of the fixed frame 501. 505 is slidably set in the through groove on the side wall of the fixed frame 501. One side of the L-shaped clamp 700 is fixed to the end of the connecting block 505. The operator drives the two fixed frames 501 to move closer to each other through the transverse clamping assembly 600. After the L-shaped clamp 700 on the side wall of the fixed frame 501 is attached to the transverse side wall of the box plate, the operator rotates the handle 504. The handle 504 drives the double-acting screw 503 to rotate. When the double-acting screw 503 rotates, it drives the two movable blocks 502 connected by threads on both sides of the surface to move closer to each other. The two movable blocks 502 drive the L-shaped clamp 700 to move synchronously through the connecting block 505. Thus, the two L-shaped clamps 700 move closer to each other in the longitudinal direction to clamp the fixed box plate.
[0028] According to another embodiment of the present invention, such as Figure 1, Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the transverse clamping assembly 600 includes two drive slots 400 formed on both sides of the interior of the worktable 200. A movable column 401 is slidably disposed within each drive slot 400. Connecting columns 403 are provided on both sides of the upper part of the movable column 401. A sliding groove adapted to the connecting column 403 is formed on the surface of the worktable 200. The connecting column 403 is slidably disposed within the sliding groove, and its upper end is fixed to the lower wall of the fixing frame 501. The transverse clamping assembly 600 also includes a drive frame 601 disposed on the side wall of the worktable 200. 1 is equipped with a driving component, which is used to drive the two movable columns 401 to move closer to each other. When the box plate is placed on the upper surface of the workbench 200, the driving component drives the two movable columns 401 to move closer to each other. The movable columns 401 drive the upper connecting column 403 to move synchronously, and the connecting column 403 drives the upper fixed frame 501 to move, so that when the two movable columns 401 move closer to each other, they will drive the two upper fixed frames 501 to move closer to each other synchronously, so that the L-shaped clamping plate on the side wall of the fixed frame 501 can clamp the fixed box plate from the lateral direction.
[0029] Specifically, the driving component includes a gear 602 rotatably disposed at the center of the drive frame 601. Guide rods 603 are provided on both the upper and lower sides of the drive frame 601. A rack plate 604 is slidably disposed on the surface of the guide rod 603, and the two rack plates 604 are respectively meshed with the upper and lower sides of the gear 602. A fixing post 402 is provided on one side wall of each rack plate 604. A connecting groove adapted to the fixing post 402 is formed on the inner side wall of the drive frame 601, and the connecting groove communicates with the interior of the drive groove 400. The fixing post 402 is slidably disposed within the connecting groove, and its end is fixed to one side of the movable post 401. On the wall, a rotating component is provided at the center of the outer wall of the drive frame 601. The rotating component is used to drive the gear 602 to rotate. The operator drives the gear 602 to rotate through the rotating component. Since the gear 602 is meshed with the rack plates 604 on the upper and lower sides, when the gear 602 rotates, it will drive the rack plates 604 to slide on the surface of the guide rod 603. At the same time, the rack plates 604 drive the fixed column 402 to slide in the connecting groove, so that the fixed columns 402 fixed on the side walls of the two rack plates 604 move closer to each other. When the fixed columns 402 move closer to each other, they drive the movable column 401 to move synchronously, so that the two movable columns 401 move closer to each other.
[0030] In another embodiment of this utility model, such as Figure 1 , Figure 5 and Figure 7As shown, the rotating assembly includes a limiting plate 801 disposed at the center of the outer wall of the drive frame 601 and corresponding to the end position of the gear 602. A rotating shaft 802 is rotatably disposed at the center of the surface of the limiting plate 801. The end of the rotating shaft 802 passes through the center of the limiting plate 801, and one end of the rotating shaft 802 is connected to the center of the end of the gear 602. A fixing block 803 is disposed at the other end of the rotating shaft 802. A limiting component 800 is disposed on the surface of the fixing block 803. The limiting component 800 is used to limit the gear 602. With the limit and fixation function in place, the worker rotates the fixing block 803, which drives the rotating shaft 802 to rotate, causing the rotating shaft 802 to drive the gear 602 to rotate. After the L-shaped clamping plate 700 has finished clamping the box plate laterally, the limiting component 800 limits and fixes the fixing block 803, preventing the fixing block 803 from rotating. The gear 602 and the rotating shaft 802 will also be limited and fixed along with the fixing block 803, preventing the gear 602 from rotating uncontrollably and improving the stability of the clamping process.
[0031] Specifically, the limiting component 800 includes a threaded hole at the end of the fixing block 803. A screw 804 is threadedly connected to the threaded hole at the end of the fixing block 803. A rotating block 805 is provided at one end of the screw 804. After the gear 602 rotates, the operator holds the rotating block 805 and rotates it. The rotating block 805 drives the screw 804 to rotate. At this time, the rotating block 805 drives the screw 804 to rotate around its own center axis. Since the screw 804 is threadedly connected to the threaded hole of the fixing block 803, the screw 804 moves closer to the surface of the limiting plate 801 while rotating, so that the end of the screw 804 presses against the surface of the limiting plate 801. The friction force is increased by the screw 804 pressing against the limiting plate 801 to fix it, thereby limiting and fixing the fixing block 803.
[0032] A fixing rod 806 is provided at the center of the end of the rotating block 805. A bearing 807 is installed on the surface of the fixing rod 806. The fixing rod 806 is fixed to the inner ring of the bearing 807. A sleeve 808 is fixed to the outer ring of the bearing 807. When the operator needs to rotate the gear 602 again, the rotating block 805 is rotated in the opposite direction, so that the end of the screw 804 is disengaged from the surface of the limiting plate 801. Then, the sleeve 808 is held and rotated. With the cooperation of the bearing 807, the fixing rod 806 and the screw 804 will not rotate around their own center, but will follow the fixing plate and rotate around the center of the rotating shaft 802 to drive the gear 602 to rotate, making the operation more convenient.
[0033] How to use this utility model:
[0034] First, it needs to be clarified that this utility model relates to panel clamping, mainly used for clamping and fixing panel during panel clamping. It should be noted that the clamping mechanism 300 is a common clamping device in the prior art. Since it is not a key technical feature of this utility model, its model will not be limited, nor will its structure be described in detail. Only the usage and installation position of the omnidirectional clamping mechanism will be described in detail. When clamping a panel, the panel is placed at the center of the upper surface of the workbench 200. Then, the sleeve 808 is rotated, causing the fixing block 803 and the rotating shaft 802 to rotate. The rotating shaft 802 drives the gear 602 to rotate. When the gear 602 rotates, it causes the rack plate 604 to slide on the surface of the guide rod 603. Simultaneously, the rack plate 604 causes the fixing column 402 to slide in the connecting groove, bringing the fixing columns 402 fixed to the side walls of the two rack plates 604 closer together. When the two movable columns 401 move closer together, they move synchronously, causing the two upper fixed frames 501 to move closer together. This allows the L-shaped clamping plates on the side walls of the fixed frames 501 to clamp the fixed panel laterally. After the L-shaped clamping plates 700 are attached to the lateral side walls of the panel, the handle 504 is rotated. The handle 504 drives the double-acting screw 503 to rotate. When the double-acting screw 503 rotates, it drives the two movable blocks 502 connected by threads on both sides of the surface to move closer together. This causes the two movable blocks 502 to move synchronously through the connecting block 505, so that the two L-shaped clamping plates 700 move closer together longitudinally to clamp and fix the panel. This allows the L-shaped clamping plates 700 to clamp and fix the panel both longitudinally and laterally, preventing the panel from shifting position and making the surface stress more uniform during panel pressing, thus improving the quality of the finished panel.
[0035] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
