Description

Technical Field

[0001] This utility model relates to the field of installation tooling, and in particular to an installation tooling for welding the bottom guide rails of a forklift cab. Background Technology

[0002] In the forklift manufacturing industry, the welding of the bottom guide rails of the cab is an important process to ensure the structural stability and installation accuracy of the cab. To ensure that the guide rails can maintain accurate position during the welding process, it is usually necessary to use special installation fixtures for auxiliary positioning and support. These fixtures are the basic equipment for achieving efficient and high-quality welding of the guide rails.

[0003] However, existing installation fixtures for welding guide rails at the bottom of forklift cabs have significant limitations in their structural design: their overall structure is difficult to flexibly adapt to the welding and installation needs of guide rails of different specifications, and cannot provide a stable and reliable support foundation for the guide rails, which can easily lead to guide rail displacement or shaking during the welding process, affecting operational stability; at the same time, the assembly method between the main body of the fixture and the auxiliary plates is relatively complex, often requiring a variety of special tools, and the assembly steps are cumbersome, which not only consumes a lot of time, but also seriously restricts assembly efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an installation fixture for welding the bottom guide rails of a forklift cab. This fixture solves the technical problem that the assembly method between the main body and auxiliary plates of the aforementioned fixture is complex, often requiring multiple specialized tools and involving cumbersome assembly steps, which not only consumes a lot of time but also severely restricts assembly efficiency.

[0005] To achieve the above objectives, this application provides the following technical solution: an installation fixture for welding bottom guide rails of a forklift cab, comprising a main body, a first sub-plate, and a second sub-plate, wherein the second sub-plate and the first sub-plate are respectively assembled on both sides of the main body, and the second sub-plate and the first sub-plate are connected to the main body via an assembly mechanism, wherein the assembly mechanism includes a locking block and a locking groove block, and the locking block is connected to the main body; The slot block is connected to the first sub-plate and the second sub-plate. The inner cavity of the slot block is provided with an assembly groove. The inner cavity of the assembly groove is slidably connected to a piston rod and a piston plate. Hollow boxes are inserted into both the upper and lower ends of the slot block. A card arm is slidably connected to the inner cavity of the hollow box. A first elastic element is connected between the card arm and the hollow box.

[0006] During assembly, the locking block is aligned with the locking slot block and inserted. The locking arm is squeezed by the locking block and slides into the hollow box, and the first elastic element is compressed. When the locking block is inserted into the assembly slot and aligned with the locking arm, the first elastic element is reset, pushing the locking arm to slide into the assembly slot, so as to realize the quick locking of the main body and the sub-plate. When disassembly is required, press the piston rod to generate air pressure in conjunction with the assembly slot. The air pressure drives the piston plate to push out the retaining arm, thus completing the disassembly.

[0007] No additional fasteners are required, improving assembly efficiency. The fit between the clamping arm and the assembly slot ensures connection stability, prevents sub-plate misalignment during welding, and improves guide rail welding accuracy.

[0008] Preferably, both the second sub-plate and the main body are provided with grooves on their exteriors, and reinforcing ribs are embedded in the inner cavity of the grooves.

[0009] The groove provides positioning and installation space for the reinforcing ribs, ensuring that the reinforcing ribs are accurately embedded and fit against the surface of the main component and the second sub-plate; The reinforcing ribs enhance the structural strength of the main component and the second sub-plate, preventing the tooling from deforming under the welding pressure of the guide rail and extending the service life of the tooling. At the same time, the groove design prevents the reinforcing ribs from protruding from the tooling surface and avoids interfering with the welding operation of the guide rail.

[0010] Preferably, the main body includes a horizontal shaft, with vertical shafts connected to both sides of the horizontal shaft. The vertical shafts are connected to the second sub-plate and the first sub-plate, and a reinforcing inclined arm is directly provided between the vertical shaft and the horizontal shaft.

[0011] The horizontal axis serves as the basic support structure for the main component, bearing the weight of the overall tooling and the force exerted during guide rail welding; the vertical axis connects vertically to the horizontal axis and is used to dock with the first and second sub-plates; the reinforcing oblique arm connects the vertical axis and the horizontal axis at an angle, forming a stable triangular structure to disperse the stress at the connection between the vertical axis and the horizontal axis. The triangular structure has excellent resistance to deformation, which can prevent the weld joint from breaking or bending after the vertical and horizontal axes are subjected to long-term stress, thus ensuring the overall stability of the main body and ensuring the positioning accuracy during guide rail welding.

[0012] Preferably, the inner cavity of the card slot block is provided with a sliding groove, and the inner cavity of the sliding groove is slidably connected to the outside of the card block.

[0013] The shape and size of the slide groove match the exterior of the card block, and the slide groove guides the movement direction of the card block when the card block is inserted into the card slot block; To avoid misalignment or jamming during insertion of the locking block, the assembly mechanism is precisely aligned, improving assembly efficiency. At the same time, the sliding cooperation between the slide and the locking block reduces friction and wear between them, extending the service life of the assembly mechanism.

[0014] Preferably, the outer surface of the clamping arm is designed with a slope, and the outer surface of the clamping arm is slidably connected to the inner cavity of the assembly groove.

[0015] When the card block is inserted into the card slot, the end of the card block first contacts the inclined surface of the card arm. The inclination angle of the inclined surface decomposes the squeezing force of the card block into a component force that pushes the card arm to slide into the hollow box. Pre-assembly can be completed without manual pressing of the card arm. When the card arm is aligned with the assembly slot, the card arm slides into the assembly slot. The reverse of the inclined surface can prevent the card block from easily coming out.

[0016] Preferably, the inner cavity of the assembly groove is provided with a partition, and a second elastic element is provided between the partition and the clamping arm and between the piston rod and the assembly groove. A hinge is provided inside the piston rod, and a pressure plate is provided at the top of the piston rod.

[0017] The partition divides the assembly slot into independent areas, each accommodating the locking arm, piston rod, and second elastic element, preventing interference between the components during operation. During disassembly, pressing the pressure plate causes the piston rod to slide downwards. The piston rod adjusts its angle via a hinge, squeezing the second elastic element on the corresponding side and simultaneously pushing the locking arm out of the assembly slot, thus separating the locking block from the slot block. After the pressing action is completed, the second elastic element can drive the piston rod and locking arm to reset, facilitating the next assembly.

[0018] In summary, this application provides an installation fixture for welding the bottom guide rails of a forklift cab, which has the following advantages: This installation fixture for welding guide rails at the bottom of forklift cabs, through its combined structure of a main body, a first sub-plate, and a second sub-plate, adapts to the installation requirements during guide rail welding, providing a stable support foundation for the guide rails and improving operational stability during the welding process. The assembly mechanism features a locking block and locking slot design. During assembly, simply align the locking block with the locking slot and insert it; the locking arm, after being compressed, achieves quick engagement through the reset function of the first elastic element, eliminating the need for complex tools. This significantly simplifies the assembly steps between the main body and the sub-plate, saving assembly time and improving assembly efficiency. When disassembly is required, simply pressing the piston rod utilizes the air pressure generated within the assembly slot to drive the piston plate, easily completing the disassembly operation. This avoids the cumbersome steps or component damage that may occur with traditional disassembly methods, making the fixture's assembly and disassembly process more convenient and flexible. This facilitates subsequent maintenance, replacement, or adjustment of the fixture, while also reducing wear and tear on fixture components caused by improper assembly and disassembly, extending the fixture's service life.

[0023] This application provides a technical solution; please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3 An installation fixture for welding bottom guide rails of a forklift cab includes a main body 1, a first sub-plate 2 and a second sub-plate 3. The second sub-plate 3 and the first sub-plate 2 are respectively assembled on both sides of the main body 1. The second sub-plate 3 and the first sub-plate 2 are connected to the main body 1 through an assembly mechanism 4. The assembly mechanism 4 includes a locking block 41 and a locking groove block 42. The locking block 41 is connected to the main body 1. The slot block 42 is connected to the first sub-plate 2 and the second sub-plate 3. The inner cavity of the slot block 41 is provided with an assembly groove 43. The inner cavity of the assembly groove 43 is slidably connected to the piston rod 44 and the piston plate 46. Hollow boxes 47 are inserted into both the upper and lower ends of the slot block 42. The inner cavity of the hollow box 47 is slidably connected to the slot arm 48. A first elastic element 49 is connected between the slot arm 48 and the hollow box 47.

[0024] During assembly, the locking block 41 is aligned with the locking slot block 42 and inserted. The locking arm 48 is pressed by the locking block 41 and slides into the hollow box 47, and the first elastic element 49 is compressed. When the locking block 41 is inserted into the assembly slot 43 and aligned with the locking arm 48, the first elastic element 49 is reset, pushing the locking arm 48 into the assembly slot 43, thereby realizing the quick engagement of the main body 1 and the sub-plate. When disassembly is required, press the piston rod 44 to generate air pressure in conjunction with the assembly groove 43. The air pressure drives the piston plate 46 to push out the retaining arm 48, thus completing the disassembly.

[0025] No additional fasteners are required, improving assembly efficiency. Furthermore, the cooperation between the clamping arm 48 and the assembly slot 43 ensures connection stability, prevents the sub-plate from shifting during the welding process, and improves the welding accuracy of the guide rail.

[0026] The second subplate 3 and the main body 1 are both provided with grooves on their exteriors, and reinforcing ribs are embedded in the inner cavity of the grooves.

[0027] The groove provides positioning and installation space for the reinforcing rib, ensuring that the reinforcing rib is accurately embedded and fits against the surfaces of the main component 1 and the second sub-plate 3; The reinforcing ribs enhance the structural strength of the main component 1 and the second sub-plate 3, preventing the tooling from deforming under the welding pressure of the guide rail and extending the service life of the tooling. At the same time, the groove design prevents the reinforcing ribs from protruding from the tooling surface and prevents interference with the welding operation of the guide rail.

[0028] The main body 1 includes a horizontal shaft, with vertical shafts connected to both sides of the horizontal shaft. The vertical shafts are connected to the second sub-plate 3 and the first sub-plate 2, and a reinforcing inclined arm is directly provided between the vertical shaft and the horizontal shaft.

[0029] The horizontal axis serves as the basic support structure of the main component 1, bearing the weight of the overall tooling and the force exerted during the welding of the guide rails; the vertical axis is vertically connected to the horizontal axis and is used to dock with the first and second sub-plates; the reinforcing oblique arm connects the vertical axis and the horizontal axis at an angle, forming a stable triangular structure to disperse the stress at the connection between the vertical axis and the horizontal axis. The triangular structure has excellent resistance to deformation, which can prevent the weld joint from breaking or bending after the vertical and horizontal axes are subjected to long-term stress, thus ensuring the overall stability of the main body 1 and ensuring the positioning accuracy during guide rail welding.

[0030] The inner cavity of the card slot block 42 is provided with a sliding groove, and the inner cavity of the sliding groove is slidably connected to the outside of the card block 41.

[0031] The shape and size of the slide groove match the outside of the card block 41. When the card block 41 is inserted into the card slot block 42, the slide groove guides the movement direction of the card block 41. To prevent the insertion of the locking block 41 from shifting or getting stuck, the assembly mechanism 4 is precisely aligned, improving assembly efficiency. At the same time, the sliding fit between the slide and the locking block 41 reduces friction and wear between them, extending the number of uses of the assembly mechanism 4.

[0032] The outer surface of the clamping arm 48 is designed with a slope, and the outer surface of the clamping arm 48 is slidably connected to the inner cavity of the assembly groove 43.

[0033] When the locking block 41 is inserted into the locking slot block 42, the end of the locking block 41 first contacts the inclined surface of the locking arm 48. The inclination angle of the inclined surface decomposes the squeezing force of the locking block 41 into a component force that pushes the locking arm 48 to slide into the hollow box 47. Pre-assembly can be completed without manual pressing of the locking arm 48. When the locking arm 48 is aligned with the assembly slot 43, the locking arm 48 slides into the assembly slot 43. The reverse of the inclined surface can prevent the locking block 41 from easily coming out.

[0034] The inner cavity of the assembly slot 43 is provided with a partition 411. A second elastic element 410 is provided between the partition 411 and the clamping arm 48 and between the piston rod 44 and the assembly slot 43. A hinge 45 is provided inside the piston rod 44 and a pressure plate is provided on the top of the piston rod 44. The outer rod part of the piston rod 44 can be folded through the hinge 45, thereby preventing the piston rod 44 from being accidentally touched by the environment or human factors when it does not need to move, thereby increasing the overall stability of the device.

[0035] The partition 411 divides the assembly slot 43 into independent areas, which respectively accommodate the locking arm 48, the piston rod 44 and the second elastic element 410, avoiding mutual interference when the components move. During disassembly, pressing the pressure plate causes the piston rod 44 to slide downward. The piston rod 44 adjusts its angle through the hinge 45, squeezing the second elastic element 410 on the corresponding side, and at the same time pushing the locking arm 48 out of the assembly slot 43, realizing the separation of the locking block 41 and the locking groove block 42. After the pressing action is completed, the second elastic element 410 can drive the piston rod 44 and the locking arm 48 to reset, which is convenient for the next assembly.
