Description

Technical Field

[0001] This invention relates to the field of chassis transportation technology, and more specifically to a tooling trolley. Background Technology

[0002] The chassis (or frame) of a pickup truck is the core of its non-load-bearing body structure, serving as the "backbone" of the entire vehicle. It is responsible for bearing the weight of the engine, transmission, body, cargo, and other components, as well as withstanding various forces and torques during driving. Therefore, chassis assembly is a crucial and preliminary step in the overall vehicle production process.

[0003] Traditional chassis assembly lines typically use ground-mounted chains or roller conveyors, with fixed or slowly moving workstations where operators complete assembly tasks. However, ground-mounted chains or roller conveyors suffer from extremely poor flexibility, lack of scalability, limited process layout, large space requirements, high civil engineering demands, and cumbersome maintenance during malfunctions. Summary of the Invention

[0004] This invention provides a tooling trolley to solve the problems of poor flexibility, lack of flexibility, insufficient scalability, limited process layout, large space occupation, high civil engineering requirements, and complicated fault maintenance of ground drag chains or roller conveyors.

[0005] This invention provides a tooling trolley, comprising: The trolley body has a placement position, and a support component is provided around the placement position to support the frame. The trolley body is provided with a connection part for connecting with the automated guided vehicle, and the connection part cooperates with the traction pin of the automated guided vehicle. The bottom of the trolley body has a moving component.

[0006] Beneficial effects: The connection design between the automated guided vehicle and the trolley body realizes the automation and flexibility of frame transportation, effectively solving the problems of poor flexibility and insufficient scalability of traditional ground drag chain or roller conveyor methods. The moving components at the bottom of the trolley body, together with the traction of the automated guided vehicle, make the entire transportation process smoother, and the process layout is no longer restricted, which greatly saves space, reduces civil engineering requirements, simplifies the maintenance of the tooling trolley, and improves production efficiency.

[0007] In one alternative embodiment, a limiting component is provided on the trolley body, and the limiting component is disposed on one side of the support component.

[0008] Beneficial effects: The limiting components can be used for positioning and limiting to prevent the chassis from falling out of its placement position during hoisting.

[0009] In one optional embodiment, the limiting component includes a positioning member and a positioning rod, the positioning rod being disposed on one side of the support component, and the positioning member being disposed on the top of the positioning rod, the positioning member being used to limit the frame on the support component.

[0010] Beneficial effects: The positioning element can hold the frame against one side, thereby limiting the frame in the horizontal direction and preventing the frame from shifting horizontally during transportation.

[0011] In one optional embodiment, a slide block is provided at the top of the positioning rod, the slide block has a sliding groove, the positioning member is slidably connected to the sliding groove, and the slide block has a fixing structure for fixing the positioning member.

[0012] Beneficial effects: The sliding positioning component greatly enhances the versatility and flexibility of the tooling trolley, enabling it to adapt to the transportation needs of various frame sizes. Operators can easily adjust the position of the positioning component according to the specific dimensions of the frame, ensuring the stability and safety of the frame during transportation.

[0013] In one optional embodiment, the fixing structure includes a plurality of first fixing holes and a fixing member. The plurality of first fixing holes are spaced apart along the guide direction of the slide groove. The positioning member has a second fixing hole that mates with the first fixing holes. The fixing member passes through the first fixing holes and the second fixing holes in sequence to fix the fixing member.

[0014] Beneficial effects: This fixing method features a simple structure and convenient operation, enabling quick fixing and disassembly of the positioning components. When the position of the positioning component needs to be adjusted, simply pull out the fixing component, slide the positioning component to the appropriate position, and then insert the fixing component again to complete the fixing. This greatly improves adjustment efficiency, reduces operation time, and further enhances the ease of use of the tooling trolley. Simultaneously, the multiple first fixing holes provide multiple adjustment positions, enabling more precise fulfillment of the positioning requirements of different frames.

[0015] In one optional embodiment, the top of the positioning rod is further provided with an adapter seat, the adapter seat having a horizontal part and a vertical part, the horizontal part being fixedly connected to the positioning rod, and the vertical part being fixedly connected to the slide.

[0016] Beneficial effects: The L-shaped adapter design not only enhances the connection stability between the positioning rod and the slide, but also makes the entire limiting assembly more compact and rational in structure. At the same time, the adapter facilitates the installation and disassembly of the limiting assembly, improving the maintenance efficiency of the tooling trolley.

[0017] In one optional embodiment, the adapter has a first stiffener and a second stiffener, the first stiffener being connected to the horizontal portion and the vertical portion respectively, the second stiffener being disposed on the side of the vertical portion opposite to the first stiffener, and the second stiffener being fixedly connected to the vertical portion and the slide block respectively.

[0018] Beneficial effects: The first stiffener effectively enhances the strength of the connection between the horizontal and vertical parts, preventing deformation under stress. The second stiffener improves the connection between the adapter and the slide, ensuring that the entire limiting assembly remains stable under the weight of the frame and various forces during transportation, without loosening or damage, thus guaranteeing the safety and reliability of the frame during transportation.

[0019] In one optional embodiment, the support assembly includes a pair of front support frames and a pair of rear support frames. The pair of front support frames are disposed on the side of the trolley body closer to the automated guided vehicle and are spaced apart. The pair of rear support frames are disposed on the side of the trolley body away from the automated guided vehicle and are spaced apart.

[0020] Beneficial effects: A pair of front support frames and a pair of rear support frames are located at the four corners of the placement position, forming a stable support frame to support the vehicle frame. The spacing between the front and rear support frames ensures greater stability of the vehicle frame during placement, preventing deformation or damage caused by concentrated stress. This layout also facilitates loading and unloading operations for the operators, improving work efficiency.

[0021] In one alternative embodiment, the contact surfaces of the front support frame and the rear support frame with the vehicle frame have flexible cushioning elements.

[0022] Beneficial effects: Flexible buffer components can buffer and dampen shocks, effectively reducing damage to the chassis caused by vibration during transportation. At the same time, flexible buffer components can also increase the friction between the chassis and the support components, preventing the chassis from sliding or shifting during transportation, further improving the safety and stability of transportation.

[0023] In one optional embodiment, the moving component includes a plurality of casters and a plurality of caster guards, the caster guards being fixedly disposed at the bottom of the trolley body, the casters being disposed within the caster guards, and the casters corresponding one-to-one with the caster guards.

[0024] Beneficial effects: Caster wheel guards serve to prevent foot crush and also protect the casters from damage caused by accidental collisions during movement. When the tooling trolley moves on uneven ground, the caster wheel guards reduce the impact of ground protrusions on the casters, extending their service life. Attached Figure Description

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

[0029] The following is combined with Figures 1 to 3 The following describes embodiments of the present invention.

[0030] According to an embodiment of the present invention, a tooling trolley is provided, comprising: a trolley body 1, the trolley body 1 having a placement position 2, a support component 3 being provided on the periphery of the placement position 2, the support component 3 being used to support the trolley frame, the trolley body 1 having a connecting part 4 for connecting to an automated guided vehicle, the connecting part 4 cooperating with a traction pin of the automated guided vehicle, and a moving component 5 being provided at the bottom of the trolley body 1.

[0031] Specifically, the trolley body 1 is rectangular in shape when viewed from above and below. The trolley body 1 has a placement position 2 for placing the frame, and support components 3 for supporting the frame are provided around the placement position 2. The trolley body 1 can be moved via a moving component 5. The trolley body 1 is provided with a connecting part 4, which is a traction hole. An automated guided vehicle (not shown) is positioned in front of the trolley body 1, and the rear of the automated guided vehicle has a traction pin (not shown). The traction pin is inserted into the traction hole to connect the automated guided vehicle to the trolley body 1. Moving the automated guided vehicle will move the trolley body 1. The automated guided vehicle is a known and publicly disclosed technical means, and therefore will not be described in detail.

[0032] The tooling trolley disclosed in this embodiment achieves automation and flexibility in frame transportation through the connection design between the automatic guide vehicle and the trolley body 1. It effectively solves the problems of poor flexibility and insufficient scalability of traditional ground drag chain or roller conveyor methods. The moving component 5 at the bottom of the trolley body 1, together with the traction of the automatic guide vehicle, makes the entire transportation process smoother and the process layout is no longer restricted, which greatly saves space, reduces civil engineering requirements, simplifies the maintenance of the tooling trolley, and improves production efficiency.

[0033] In one embodiment, a limiting component 6 is provided on the trolley body 1, and the limiting component 6 is located on one side of the support component 3.

[0034] Specifically, such as Figure 1 As shown, the limiting component 6 is located on the side of the support component 3 near the automated guided vehicle. The frame is hoisted onto the trolley body 1 by a hoisting device. The limiting component 6 can play the role of positioning and limiting, preventing the frame from leaving the placement position 2 during hoisting.

[0035] In one embodiment, the limiting component 6 includes a positioning member 61 and a positioning rod 62. The positioning rod 62 is disposed on one side of the support component 3, and the positioning member 61 is disposed on the top of the positioning rod 62. The positioning member 61 is used to limit the frame on the support component 3.

[0036] Specifically, such as Figure 3 As shown, the positioning element 61 is set at the top of the positioning rod 62. When the frame is placed on the support assembly 3, the positioning element 61 can abut against one side of the frame, thereby limiting the frame in the horizontal direction and preventing the frame from shifting horizontally during transportation.

[0037] In one embodiment, a slide block 63 is provided on the top of the positioning rod 62. The slide block 63 has a slide groove 631, the positioning member 61 is slidably connected to the slide groove 631, and the slide block 63 has a fixing structure 632 for fixing the positioning member 61.

[0038] Specifically, such as Figure 3 As shown, the positioning component 61 consists of a positioning pin 611 and an inverted U-shaped base 612. The positioning pin 611 is fixed to the upper end face of the inverted U-shaped base 612. The slide block 63 consists of two rectangular side plates 633 and a rectangular connecting block 634. The two side plates 633 are respectively fixed on the left and right sides of the connecting block 634. The perimeter of the left and right sides of the connecting block 634 is smaller than the perimeter of the side plates 633 facing the end face of the connecting block 634. The upper side of the connecting block 634 is constructed as a sliding groove 631. Both sides of the U-shaped groove have a bent portion 6122 that bends toward the other side wall. The bent portion 6122 is perpendicular to the side wall of the U-shaped groove. The bent portion 6122 forms a snap-fit ​​part. The bent portion 6122 snaps onto the bottom surface of the connecting block 634 to prevent the inverted U-shaped base 612 from falling off the connecting block 634. The U-shaped groove of the inverted U-shaped base 612 is slidably connected to the slide groove 631, allowing the inverted U-shaped base 612 to slide relative to the slide groove 631 along its guide direction. This adjusts the position of the positioning pin 611. When the positioning pin 61 slides to the appropriate position, the fixing member 6322 secures the positioning pin 61 to the slide 63. The slidable positioning pin 61 greatly enhances the versatility and flexibility of the tooling trolley, enabling it to adapt to the transportation needs of various frame specifications. Operators can easily adjust the position of the positioning pin 61 according to the specific dimensions of the frame, ensuring the stability and safety of the frame during transportation.

[0039] In one embodiment, the fixing structure 632 includes a plurality of first fixing holes 6321 and a fixing member 6322. The plurality of first fixing holes 6321 are spaced apart along the guide direction of the slide groove 631. The positioning member 61 has a second fixing hole 6121 that cooperates with the first fixing hole 6321. The fixing member 6322 passes through the first fixing hole 6321 and the second fixing hole 6121 in sequence to fix the fixing member 6322.

[0040] Specifically, such as Figure 3As shown, the fixing structure 632 includes three first fixing holes 6321 penetrating the front and rear sides of the connecting block 634. The fixing element 6322 is a spring pin. Second fixing holes 6121 are provided on both sides of the U-shaped groove. The spring pin passes through the second fixing holes 6121 and the second fixing holes 6121, that is, the inverted U-shaped base 612 is fixed on the connecting block 634 to limit the inverted U-shaped base 612. This fixing method has a simple structure and is easy to operate. It can quickly fix and disassemble the positioning element 61. When it is necessary to adjust the position of the positioning element 61, simply pull out the fixing element 6322, slide the positioning element 61 to the appropriate position, and then insert the fixing element 6322 to complete the fixation. This greatly improves the adjustment efficiency, reduces the operation time, and further enhances the ease of use of the tooling trolley. At the same time, the setting of multiple first fixing holes 6321 provides multiple adjustment positions, which can more accurately meet the positioning requirements of different frames.

[0041] In other alternative embodiments, the fixing structure 632 may include two or four or other numbers of first fixing holes 6321. The number of first fixing holes 6321 may be determined by the type of vehicle frame to be transported and the length of the connecting block 634, and is not specifically limited here.

[0042] In one embodiment, the top of the positioning rod 62 is also provided with an adapter 64, which has a horizontal part and a vertical part. The horizontal part is fixedly connected to the positioning rod 62, and the vertical part is fixedly connected to the slide 63.

[0043] Specifically, such as Figure 3 As shown, the positioning rod 62 is fixedly connected to the slide 63 via the adapter 64. The horizontal and vertical parts of the adapter 64 form an L-shaped structure. The horizontal part is fixedly connected to the positioning rod 62 by bolts, and the vertical part is fixedly connected to the slide 63.

[0044] The L-shaped adapter 64 design not only enhances the connection stability between the positioning rod 62 and the slide 63, but also makes the entire limiting assembly 6 more compact and rational in structure. At the same time, the adapter 64 facilitates the installation and disassembly of the limiting assembly 6, improving the maintenance efficiency of the tooling trolley.

[0045] In one embodiment, the adapter 64 has a first stiffener 641 and a second stiffener 642. The first stiffener 641 is connected to the horizontal part and the vertical part respectively, and the second stiffener 642 is disposed on the side of the vertical part away from the first stiffener 641. The second stiffener 642 is fixedly connected to the vertical part and the slide 63 respectively.

[0046] Specifically, such as Figure 3As shown, the first stiffening member 641 is located at the inner angle between the horizontal and vertical parts of the adapter 64. Its two right-angled sides are welded and fixed to the horizontal and vertical parts respectively, which can effectively enhance the strength of the connection between the horizontal and vertical parts and prevent deformation under stress. The second stiffening member 642 is located on the side of the vertical part away from the first stiffening member 641. One right-angled side is welded and fixed to the vertical part, and the other right-angled side is welded and fixed to the slide 63. This further improves the connection between the adapter 64 and the slide 63, so that the entire limiting assembly 6 can remain stable when bearing the weight of the frame and various forces during transportation, without loosening or damage, thereby ensuring the safety and reliability of the frame transportation.

[0047] In one embodiment, the support assembly 3 includes a pair of front support frames 31 and a pair of rear support frames 32. The pair of front support frames 31 are disposed on the side of the trolley body 1 close to the automated guided vehicle and are spaced apart. The pair of rear support frames 32 are disposed on the side of the trolley body 1 away from the automated guided vehicle and are spaced apart.

[0048] Specifically, such as Figure 1 As shown, the front support frame 31 is located at the front of the trolley body 1, and the rear support frame 32 is located at the rear of the trolley body 1. A pair of front support frames 31 and a pair of rear support frames 32 are respectively located at the four corners of the placement position 2, together forming a stable support frame for supporting the trolley frame. The spaced arrangement of the front support frames 31 and rear support frames 32 ensures greater stability of the trolley frame during placement, avoiding deformation or damage caused by concentrated stress. At the same time, this layout facilitates loading and unloading operations for operators, improving work efficiency.

[0049] Furthermore, such as Figure 1 As shown, a button box 7 is installed on any of the front support frames 31. The button box 7 is connected to the controller signal of the automated guided vehicle. The automated guided vehicle can be controlled to move forward, backward and stop through the button box 7.

[0050] In one embodiment, the contact surfaces of the front support frame 31 and the rear support frame 32 with the vehicle frame have flexible buffers 33.

[0051] Specifically, such as Figure 1 As shown, the flexible buffer 33 is made of elastic materials such as rubber or polyurethane. When the frame is placed on the support assembly 3, the flexible buffer 33 can buffer and dampen the shock, effectively reducing the damage to the frame caused by vibration during transportation. At the same time, the flexible buffer 33 can also increase the friction between the frame and the support assembly 3, preventing the frame from sliding or shifting during transportation, further improving the safety and stability of transportation.

[0052] In other embodiments, the shape of the flexible buffer 33 is adapted to the contact surface of the frame, allowing it to fit snugly against the frame.

[0053] In one embodiment, the moving component 5 includes a plurality of casters 51 and a plurality of caster guards 52. The caster guards 52 are fixedly installed at the bottom of the trolley body 1, and the casters 51 are installed inside the caster guards 52. The casters 51 and the caster guards 52 correspond one-to-one.

[0054] Specifically, such as Figure 2 As shown, several casters 51 and several caster guards 52 are evenly arranged on the upper and lower sides of the trolley body 1. The trolley body 1 can move via the casters 51. The caster guards 52 have cavities inside, and the brackets of the casters 51 are fixedly connected to the top plate of the caster guards 52. There is a gap between the caster guards 52 and the ground, so that there is no friction between the caster body 1 and the ground during movement. The number of casters 51 can be determined according to the length of the trolley body 1, and the specific number is not limited here. The caster guards 52 serve to prevent foot crushing. At the same time, the caster guards 52 also protect the casters 51 from damage caused by accidental collisions during movement. When the tooling trolley moves on uneven ground, the caster guards 52 can reduce the impact of ground protrusions on the casters 51, extending the service life of the casters 51.

[0055] Furthermore, such as Figure 2 As shown, casters 51 are located at the four corners of the trolley body 1. The moving component 5 also includes directional wheels 53, which are positioned between the two casters 51 on the upper and lower sides of the trolley body 1. The directional wheels 53 are housed within the caster guard plate 52 and are shock-absorbing wheels, serving both orientation and support functions. After the trolley body 1 is connected to the automated guided vehicle (AGV), the directional wheels 53 and the AGV's directional wheels 53 are collinear. This ensures that when the AGV carries the trolley body 1 and turns, the AGV's posture is consistent with that of the trolley body 1, preventing collisions between the AGV and the trolley body 1.

[0056] Furthermore, such as Figure 1 As shown, multiple material boxes 8 are also provided around the trolley body 1, with adjacent material boxes 8 spaced apart. The material boxes 8 are reserved for the placement of assembly auxiliary materials.

[0057] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
