Description

Technical Field

[0001] This utility model relates to the field of flattening machine technology, specifically to a special vehicle floor welding auxiliary flattening machine. Background Technology

[0002] In the manufacturing process of special-purpose vehicles, the welding of the vehicle floor is a crucial step. However, the traditional methods of welding the vehicle floor have many drawbacks.

[0003] In existing welding processes, welding the vehicle floor typically requires one person to hold down the floor to prevent movement or deformation during welding, while another person performs the welding operation. This method is inherently inefficient. Because it requires two people working together, the pace of the entire welding process depends entirely on their coordination. Any misalignment in coordination will hinder the welding progress, significantly reducing production efficiency.

[0004] Moreover, this method incurs very high labor costs. Hiring two workers for a relatively simple welding task undoubtedly increases a company's labor costs. Especially in today's highly competitive market environment, high labor costs can severely impact a company's competitiveness and profitability.

[0005] Furthermore, manually pressing down on the floor panel makes it difficult to ensure uniform and stable pressure. Different people may apply varying pressure, which can easily lead to localized deformation or inconsistent weld quality during the welding process, thus affecting the overall quality and lifespan of the vehicle floor panel.

[0006] In summary, the current method of welding the vehicle floor plate by having one person press down the plate while another person welds is inefficient, has high labor costs, and makes it difficult to guarantee welding quality. There is an urgent need for a new welding auxiliary equipment to change this situation. Utility Model Content

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components.

[0044] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0045] Reference Figures 1-5The first embodiment of this utility model proposes a special vehicle floor welding auxiliary flattening machine, including a support frame with a support beam 8; a vehicle frame, which is overlapped above the support beam 8; a floor plate, which is overlapped above the vehicle frame; and also includes: a frame body 1 with several crossbeams; several rotating wheels 2, which are rotatably mounted on the frame body 1 and move along the support beam 8 after rotating; and several pressure plates 3, which are respectively raised and lowered on the several crossbeams and are used to press the floor plate after descending.

[0046] In this embodiment, the support beam 8 bears the pressure of the frame and the base plate. Adjustable anchor bolts can be installed at the bottom of the support beam 8 to allow for adjustments on uneven ground and ensure the equipment's levelness. The frame adopts a welded structure, composed of crossbeams and longitudinal beams. The frame can stably rest on top of the support beam 8. The frame body 1 consists of several crossbeams and several longitudinal beams, with the crossbeams and longitudinal beams of the frame body 1 corresponding to the crossbeams and longitudinal beams of the vehicle frame for convenient and accurate welding. The rotating wheels 2 can be in the form of rollers or bearings, rotatably mounted on the frame body 1. The number and layout of the rotating wheels 2 should match the support beam 8 to ensure stable movement along the support beam 8. The pressure plates 3 can be raised and lowered hydraulically or pneumatically, corresponding to several crossbeams. The number and layout of the pressure plates 3 should correspond to the crossbeams and longitudinal beams of the vehicle frame so that when the pressure plates 3 descend, they press the base plate and the crossbeams and longitudinal beams of the vehicle frame together, facilitating welding.

[0047] The pressing action of pressure plate 3 ensures the base plate remains flat during welding, reducing welding deformation and defects, and improving welding quality. Automated control allows for rapid operation, eliminating the need for multiple operators; one person can perform welding, increasing production efficiency. Furthermore, the equipment's simple structure facilitates maintenance and upkeep, reducing maintenance costs. The equipment is easy to operate and can be automated through a control system, further reducing the labor intensity of manual operation. Finally, the equipment's stable and reliable structure ensures operator safety.

[0048] Furthermore, it also includes: hooks 4, having several hooks, one end of hooks 4 is set on the frame 1, and the other end is used by the frame 1 to form a clamping space 41, the clamping space 41 is used to clamp the support beam 8.

[0049] In this embodiment, the hooks 4 can stably clamp the support beam 8 during operation. The number of hooks 4 is determined according to the size of the frame 1 and actual needs; generally, multiple hooks 4 are provided to ensure clamping stability. The hooks 4 are designed to be curved to form a clamping space 41, effectively clamping the support beam 8. The size of the hooks 4 should be designed according to the size of the support beam 8 to ensure that the clamping space 41 can fit tightly against the support beam 8, preventing the frame 1 from shaking or shifting when the pressure plate 3 is pressed down.

[0050] When using a dedicated vehicle chassis welding auxiliary flattening machine, first, place the chassis frame on top of the support beam 8, and then place the chassis plate on top of the chassis frame. Next, move the frame 1 to a suitable position so that the clamping space 41 of the hook 4 aligns with the support beam 8, and lower the hook 4 to clamp the support beam 8. When the pressure plate 3 needs to be pressed down to squeeze the chassis plate, the chassis frame will not be lifted due to the clamping action of the hook 4, thus ensuring that the pressure plate 3 can smoothly press down to squeeze the chassis plate. During the pressing process of the pressure plate 3, pay attention to the pressure of the pressure plate 3 and the deformation of the chassis plate to ensure welding quality. After the welding work is completed, first raise the pressure plate 3, and then lift the hook 4 to release the clamp on the support beam 8. Finally, remove the frame 1 to proceed to the next step.

[0051] The clamping action of hook 4 effectively prevents the frame from being lifted when pressure plate 3 is pressed down, thus ensuring that the base plate can be welded in a stable state. This helps reduce welding deformation and defects, improving welding quality. The use of hook 4 makes the equipment more stable and reliable during operation, reducing operational interruptions and adjustment time caused by the frame being lifted. This helps improve work efficiency and shorten the production cycle. Hook 4 is simple and convenient to operate; simply lowering or raising it clamps or releases the support beam 8. This allows operators to operate quickly and accurately, improving work efficiency.

[0052] Furthermore, the frame 1 has several sliding grooves 11, and the hook 4 includes: a mounting plate 42, which overlaps above the sliding groove 11; and a first hook 43, which is disposed on the mounting plate 42, with one end of the first hook 43 passing through the sliding groove 11 and the other end forming a clamping space 41 with the frame 1.

[0053] In this embodiment, the slide groove 11 on the frame 1 has sufficient strength and wear resistance to ensure that it will not deform or be damaged during long-term use. The number and layout of the slide groove 11 are determined according to the size of the frame 1 and actual needs. Generally, multiple slide grooves 11 are provided so that the hook 4 can be adjusted in different positions to better clamp the support beam 8. The slide groove 11 is designed to be elongated, with a width slightly larger than the thickness of the mounting piece 42 of the hook 4, so that the mounting piece 42 can move smoothly within the slide groove 11. The size of the mounting piece 42 is larger than the slide groove 11 so that it can overlap the slide groove 11 and move smoothly within the slide groove 11. The first hook 43 will not deform or be damaged when clamping the support beam 8. One end of the first hook 43 passes through the slide groove 11, and the other end forms a clamping space 41 with the frame 1. The other end of the first hook 43 is designed to be curved so that it can better fit the shape of the support beam 8 and increase the stability of clamping. Based on the position and dimensions of the support beam 8, adjust the position of the mounting plate 42 within the slide groove 11 to ensure that the first hook 43 accurately clamps the support beam 8. The slide groove 11 and the movable hook 4 enhance clamping stability. Operators can quickly and accurately adjust the position of the clamping space 41 by adjusting the position of the mounting plate 42 within the slide groove 11. This makes operation more convenient and efficient, improving work productivity.

[0054] Furthermore, it also includes: a number of driving components 5, which are respectively arranged on the crossbeam. Each driving component 5 corresponds to a pressure plate 3, and one driving component 5 is used to drive one pressure plate 3 to rise and fall.

[0055] In this embodiment, the drive component 5 can be a hydraulic cylinder, pneumatic cylinder, or electromagnetic actuator, etc. The appropriate type of drive component 5 is selected based on the equipment's working requirements and actual conditions. For example, if greater driving force and stability are required, a hydraulic cylinder can be selected; if higher speed and precision are required, an electric push rod can be selected. The drive components 5 are installed on the crossbeams respectively. During installation, ensure that the position of the drive component 5 is accurate and the connection with the pressure plate 3 is firm and reliable. Fixing can be achieved using bolt connections, welding, or other methods. Simultaneously, ensure that the driving direction of the drive component 5 is consistent with the lifting direction of the pressure plate 3.

[0056] Furthermore, the hook 4 is raised and hinged on the frame 1, and also includes: a number of pads 6, which are slidably disposed on the frame 1. After the pads 6 slide, they are used to lift the hook 4.

[0057] In this embodiment, to ensure the smoothness and accuracy of the lifting and lowering of the hook 4, a guide rail can be installed on the frame 1, allowing the hook 4 to move up and down along the guide rail. A sliding rail is also installed on the frame 1, allowing the pad 6 to slide on it. The design of the sliding rail should ensure that the pad 6 can slide smoothly and will not easily disengage from the rail.

[0058] When hook 4 is needed to hook the support beam 8, first place hook 4 at a height lower than the support beam 8. Then, use a crane to directly place the frame 1 onto the support beam 8. As the frame 1 descends, hook 4 swings, with the other end of hook 4 directly below the support beam 8. The pad 6 can be slid under hook 4, and then the pad 6 can be used to lift hook 4, securing it firmly against the support beam 8. During welding, hook 4 and pad 6 maintain the stability of the support beam 8, preventing the frame from being lifted, thus ensuring that the pressure plate 3 can smoothly press against the base plate, improving welding quality.

[0059] The hook 4, with its sliding pad 6, can accommodate support beams 8 of different sizes, improving the equipment's versatility and applicability. Whether large or small, the support beams 8 can be easily hooked and secured, meeting diverse welding needs. The lifting design of the hook 4 makes hooking the support beam 8 more convenient and faster, reducing manual operation time and labor intensity. Operators can quickly lower the hook 4, hook the support beam 8, and raise it to perform welding work, improving work efficiency.

[0060] Furthermore, the hook 4 includes: a lifting rod 44, which is lifted and hinged on the frame 1; and a second hook 45, which is lifted and hinged on the lifting rod 44. The second hook 45 and the frame 1 form a clamping space 41. After the second hook 45 is lifted and hinged, it is used to clamp the support beam 8.

[0061] In this embodiment, a suitable installation position is set on the frame 1 to ensure that the lifting rod 44 can move up and down smoothly. Simultaneously, to ensure the stability of the lifting rod 44, a guide device can be installed on the frame 1 to maintain the vertical movement of the lifting rod 44 during lifting. The hinged connection between the lifting rod 44 and the frame 1 can be achieved using a pin connection or similar method, allowing the lifting rod 44 to swing within a certain angle range. This design aims to allow the lifting rod 44 to adjust its position when the frame 1 is placed onto the support beam 8 by a crane, so that the second hook 45 can accurately move directly below the support beam 8. The second hook 45 is designed with a hook-shaped structure that can cooperate well with the support beam 8. A suitable installation position and guide device are set on the lifting rod 44 to ensure that the second hook 45 can move up and down smoothly. Furthermore, to ensure that the second hook 45 can accurately engage with the support beam 8, a positioning device, such as a positioning pin or positioning block, can be installed on the second hook 45. The lifting movement of the second hook 45 can be controlled manually, electrically, or hydraulically. During operation, the operator can adjust the lifting height of the second hook 45 according to the height and position of the support beam 8, so that it can accurately engage the support beam 8.

[0062] When a special vehicle chassis welding auxiliary flattening machine is required, the frame 1 is first lifted by a crane, and then the position and height of the crane are adjusted so that the frame 1 is close to the support beam 8. During this process, the lifting rod 44 is in a lowering state and can be swung and adjusted as needed to ensure that the second hook 45 can move accurately to directly below the support beam 8.

[0063] After the second hook 45 moves directly below the support beam 8, the lifting rod 44 is raised by operating the pad 6. During the rise of the lifting rod 44, the second hook 45 is also raised until it engages with the support beam 8. At this point, the frame 1 is completely secured to the support beam 8, forming a stable clamping structure.

[0064] The second hook 45 can be raised and lowered to a suitable position to accommodate support beams 8 of different heights. This design allows the special vehicle floor welding auxiliary flattening machine to be used in various working environments, improving the equipment's versatility and applicability. The swinging motion of the lifting rod 44 and the raising and lowering operation of the second hook 45 can quickly and accurately clamp the frame 1 onto the support beam 8, reducing installation and adjustment time. Simultaneously, during the welding process, the stable clamping action of the hook 4 ensures smooth welding operations, improving work efficiency.

[0065] Furthermore, the lifting rod 44 has a slide rail 441, and the second hook body 45 is rotatably and vertically disposed within the slide rail 441. The slide rail 441 has a first protrusion 442, and the second hook body 45 has a plurality of second protrusions 451. The plurality of second protrusions 451 are spaced apart in the vertical direction to form a plurality of locking gaps 452. After the second hook body 45 rotates, the first protrusions 442 slide into or out of the locking gaps 452.

[0066] In this embodiment, a vertical slide rail 441 is machined on the lifting rod 44. The width of the slide rail 441 is slightly larger than the thickness of the second hook 45, allowing the second hook 45 to smoothly rise, fall, and rotate within the slide rail 441. A first protrusion 442 is provided on the inner wall of the slide rail 441. The second hook 45 is shaped like a curved hook to securely engage with the support beam 8. Several second protrusions 451 are machined on the second hook 45, spaced vertically to form several engagement gaps 452. Each engagement gap 452 must match the first protrusion 442, allowing the first protrusion 442 to smoothly slide into or out of the engagement gap 452.

[0067] When the height of the second hook 45 needs to be adjusted, the operator can manually or electrically rotate the second hook 45 within the slide rail 441, causing the first protrusion 442 to rotate out of the locking gap 452, thus raising or lowering it. When the position of the second hook 45 needs to be fixed, the second hook 45 can be rotated at a certain angle, causing the first protrusion 442 to slide into one of the locking gaps 452, thereby fixing the second hook 45.

[0068] The height of the second hook 45 can be precisely adjusted by the lifting and rotating of the second hook 45 within the slide rail 441, and by the locking gap 452 formed by the first protrusion 442 and the second protrusion 451. This allows the special vehicle floor welding auxiliary flattening machine to adapt to support beams 8 of different heights, improving the equipment's versatility and applicability. When the first protrusion 442 slides into the locking gap 452, it effectively prevents the second hook 45 from moving accidentally during operation. This fixing method is firm and reliable, ensuring the stability of the equipment during the welding process and improving welding quality.

[0069] Furthermore, the second hook body 45 has two rows of second protrusions 451, which are arranged circumferentially on the second hook body 45. There are two first protrusions 442, which correspond one-to-one with the two rows of second protrusions 451.

[0070] In this embodiment, each row of second protrusions 451 has several second protrusions 451 spaced vertically. The processed second hook 45 is installed into the slide rail 441 of the lifting rod 44 to ensure smooth lifting and rotation. During installation, the engagement gap 452 between the two first protrusions 442 and the two rows of second protrusions 451 must be maintained to achieve a good engagement effect.

[0071] The two rows of second protrusions 451 on the second hook 45 correspond one row to the two first protrusions 442 on the lifting rod 44, forming a more stable locking structure. This design effectively prevents the second hook 45 from shaking or shifting during operation, improving the structural stability of the equipment. Due to the double-row protrusion design, the contact area between the first protrusions 442 and the second protrusions 451 is increased, thereby improving the load-bearing capacity of the equipment.

[0072] Furthermore, it also includes: a scale line 7, which is set on the second hook body 45, and the scale line 7 is located between the two columns of second protrusions 451.

[0073] In this embodiment, a scale line 7 is made on the second hook body 45, located between the two rows of second protrusions 451, using methods such as laser engraving, printing, or machining. The scale line 7 can be equally spaced numerical scales or simple line markings, so as to clearly show the lifting position of the second hook body 45.

[0074] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
