Description

Technical Field

[0001] This invention relates to the field of vehicle frame welding technology, specifically to adjustable vehicle frame welding equipment and its usage method. Background Technology

[0002] The chassis is the foundation of the entire automobile, bearing various loads from both inside and outside the vehicle. Most components and assemblies, such as the engine, transmission system, suspension, steering system, cab, cargo box, and related control mechanisms, are fixed to the chassis. The chassis manufacturing process includes raw material selection, cutting, welding, heat treatment, machining, and surface treatment. Typically, the chassis is welded using welding equipment.

[0003] Existing welding equipment, when fixing the frame, can only hold a single size frame due to the fixed size of the clamps on the device. When welding frames of different lengths or diameters, the clamps need to be changed, affecting welding efficiency. At the same time, when welding the frame, it is usually necessary to rotate the frame itself so that the welding head can weld the frame seam from all directions. Since different types of frames occupy different spaces, the device needs to reserve enough space for frame rotation. Therefore, welding equipment of different sizes is required when welding frames of different sizes, which is very troublesome. Summary of the Invention

To simplify the disclosure of the embodiments of the present invention, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the embodiments of the present invention.

In addition, the embodiments of the present invention provide examples of various specific processes and materials, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0032] The present invention aims to overcome the shortcomings of the prior art by providing an adjustable frame welding device and method of use. By setting the clamping components, it can stably clamp frames of different sizes, while increasing the clamping area of ​​the frame and ensuring the stability of the clamping. By setting the adjusting components, it can adapt to frames of different lengths, improving the applicability of the device. By setting the welding components, it can change the position of the upper and lower welding heads, ensuring all-round welding operations on the frame. At the same time, the upper and lower welding heads work simultaneously, improving welding efficiency.

[0033] This invention provides an adjustable frame welding device and a method for using it. The adjustable frame welding device and method are described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0034] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings and specific implementation details.

[0035] Example 1 Please see Figures 1-3 In this embodiment, an adjustable frame welding device is provided, comprising: The housing 1 has a workbench 101 installed inside. The top of the workbench 101 has two slide rails 5, and the top of the slide rails 5 has a fixing plate 6. The top of the workbench 101 has a welding ring 2. The top of the housing 1 has two air compressors 4. The clamping assembly set on the fixing plate 6 is used to adapt to the clamping and fixing of different frames. The fixing plate 6 and the workbench 101 have an adjustment assembly. The welding ring 2 has a welding assembly.

[0036] The clamping components allow for the stable clamping of frames of different sizes. During clamping, the clamping block 608 can rotate adaptably to the surface of the frame, increasing the clamping area and ensuring stability. Furthermore, the adjustable components can accommodate frames of varying lengths, enhancing the equipment's versatility. The welding components allow for the alteration of the positions of the upper welding head 2023 and the lower welding head 2013, ensuring omnidirectional welding of the frame. Simultaneous operation of the upper and lower welding heads 2023 improves welding efficiency.

[0037] Example 2 Please see Figures 3-5 Based on Embodiment 1, the clamping assembly includes: a clamping groove on the top of the fixed plate 6, with two movable blocks 603 slidably connected inside the clamping groove, and a clamping plate 604 connected to the top of the movable blocks 603; multiple movable grooves 605 on one side of the clamping plate 604, with a movable plate 606 inside the movable groove 605, a clamping block 608 rotatably connected to one side of the movable plate 606 via a bearing, and rubber blocks 609 connected between the multiple clamping blocks 608; a movable spring 607 connected between the movable groove 605 and the movable plate 606; a rubber layer on the surface of the clamping block 608; a DC motor 601 installed on one side of the fixed plate 6; a threaded rod 602 driven by the DC motor 601 on one side, and one end of the threaded rod 602 connected to the inner wall of the clamping groove via a bearing; a threaded hole on the movable block 603 for use with the threaded rod 602; and two threads in opposite directions on the threaded rod 602.

[0038] When clamping and fixing the frame, the frame to be welded is placed on the fixing plate 6. Then, the DC motor 601 drives the threaded rod 602 to rotate. At this time, the threaded rod 602 drives the moving block 603 to move under the action of the threaded hole thread engagement. Since the threaded rod 602 has two sections of threads in opposite directions, the threaded rod 602 drives the two moving blocks 603 to move in opposite directions. This causes the moving blocks 603 to move towards the clamping plate 604 towards the frame, and the clamping block 608 clamps and fixes the frame. As the clamping block 608 approaches the frame, it contacts the frame, while the clamping plate 604 continues to move. At this time, the movable plate 606 compresses the movable spring 607, causing the movable spring 607 to deform elastically and generate elastic force. This elastic force is then applied to the clamping block 608, making the clamping block 608 fit tightly against the frame surface. This increases the clamping and fixing force of the clamping block 608 on the frame. Simultaneously, through the rubber block 609 between the multiple clamping blocks 608, the multiple clamping blocks 608 shift at an angle when they are in close contact with the frame, forming an arc-shaped clamping plate that can adapt to different outer surfaces of the frame, improving overall adaptability.

[0039] Please see Figure 3 , Figure 13 and Figure 14 The clamping plate 604 has an air pipe 7 inside, and multiple branch pipes are connected to the air pipe 7. The multiple branch pipes are connected to the movable groove 605 respectively. An air chamber 701 communicating with the air pipe 7 is opened inside the clamping plate 604. An air outlet pipe 402 is connected to the top of the clamping plate 604 and is connected to the air compressor 4. A blocking block 702 is provided inside the air chamber 701. An air hole is opened on the blocking block 702. A sealing block 703 is provided at the bottom of the blocking block 702. A sealing spring 704 is connected between the bottom of the sealing block 703 and the air chamber 701.

[0040] Before welding, the air compressor 4 needs to compress gas to clean the surface of the frame. During the operation of the air compressor 4, some of the compressed gas is discharged into the air chamber 701 through the air outlet pipe 402. At this time, the sealing block 703 moves downward under the action of air pressure difference, exposing the air hole. At this time, the gas in the air outlet pipe 402 can enter the air pipe 7 through the air hole and be discharged into multiple movable slots 605 through the diverter pipe on the air pipe 7. This causes the air pressure on one side of the movable plate 606 to rise and apply pressure to the movable plate 606, thereby increasing the supporting force of the movable plate 606 on the clamping block 608. After the air compressor 4 stops operating, the sealing block 703 rebounds under the action of the sealing spring 704, resealing the air hole. At this time, the air pressure inside the air pipe 7, the diverter pipe and the movable slot 605 remains unchanged, thus keeping the movable plate 606 and the clamping block 608 in their current positions and preventing loosening during the welding process.

[0041] Please see Figure 14Based on embodiment 2, the moving block 603 further includes a pressure relief chamber 705 communicating with the air pipe 7, a pressure relief block 706 inside the pressure relief chamber 705, a pressure relief spring 707 connected to one side of the pressure relief block 706, and push rods 708 connected to the inner walls of opposite sides of the clamping groove. A through hole is provided on one side of the moving block 603, and the push rods 708 correspond to the positions of the through holes. An annular pipe 3 is connected to opposite sides of the welding ring 2. Multiple air nozzles 301 arranged in a circular array are provided on the inner wall of the annular pipe 3. An air supply pipe 401 is connected to the bottom of the air compressor 4, and one end of the air supply pipe 401 is connected to the annular pipe 3.

[0042] After welding is completed, when the clamping plate 604 moves away from the frame, the moving block 603 moves closer to the push rod 708, causing the push rod 708 to insert into the through hole and squeeze the pressure relief block 706. This causes the pressure relief block 706 to move and open the connection between the air pipe 7 and the pressure relief chamber 705. At this time, the gas inside the air pipe 7 is discharged to the outside through the pressure relief chamber 705 and the through hole, so that the moving plate 606 is only subjected to the elastic force of the moving spring 607 and bounces back to its original position under the action of the elastic force. This drives the multiple clamping blocks 608 to move back to their original positions. At this time, the multiple clamping blocks 608 change from an arc shape back to a vertical state, waiting for the next clamping.

[0043] Example 3 Please see Figure 2 Based on embodiment 1, a drive block 105 is connected to the bottom of the welding ring 2, a drive groove 102 is opened on the top of the workbench 101, a drive motor 103 is installed inside the workbench 101, a drive rod 104 is driven and connected to one side of the drive motor 103, one end of the drive rod 104 is connected to the inner wall of the drive groove 102 through a bearing, the surface of the drive rod 104 is provided with threads, and a drive hole is opened inside the drive block 105 that is threadedly connected to the drive rod 104.

[0044] During welding operations, depending on the welding location, the drive motor 103 can drive the drive rod 104 to rotate, causing the drive rod 104 to move the drive block 105 under the action of the drive hole thread engagement, thereby moving the welding ring 2 to change the position of the welding ring 2 to adapt to the welding position of different frames.

[0045] Example 4 Please see Figure 3 and Figure 4Based on Embodiment 1, the adjustment component includes: two slide rails 5 installed on the top of the workbench 101, and the slide rails 5 have an I-shaped cross-section; a slider 501 connected to the bottom of the fixed plate 6, the bottom of the slider 501 has a groove 503, and the groove 503 is slidably connected to the slide rails 5, and a pulley is provided between the slide rails 5 and the groove 503; a cavity 502 opened inside the slider 501, a rotary motor 504 is installed inside the cavity 502, a rotary gear 505 is driven and connected to one side of the rotary motor 504, and a gear rack is provided on the upper surface of the slide rails 5, and the rotary gear 505 meshes with the gear rack.

[0046] Since the lengths of the frames to be welded vary, the rotary motor 504 can drive the rotary gear 505 to rotate. The rotary gear 505 meshes with the gear rack, and under the reaction force of the rotary gear 505, the slider 501 moves on the slide rail 5, thereby changing the position of the fixing plate 6 to facilitate clamping and fixing frames of different lengths. At the same time, the multiple pulleys and the I-shaped slide rail 5 can improve the smoothness of the slider 501's movement and prevent the slider 501 from tilting during the movement, thus limiting the direction of movement of the slider 501.

[0047] Example 5 Please see Figures 6-12 Based on Embodiment 1, the welding assembly includes: a first annular groove 201 and a second annular groove 202 formed inside the welding ring 2; a first limiting groove 2011 and a second limiting groove 2021 formed on the inner wall of the welding ring 2, wherein the first limiting groove 2011 and the second limiting groove 2021 are symmetrically distributed vertically, the first limiting groove 2011 communicates with the first annular groove 201, and the second limiting groove 2021 communicates with the second annular groove 202; a first annular block 2012 disposed inside the first annular groove 201, a second annular block 2022 disposed inside the second annular groove 202, a lower welding head 2013 installed on the inner wall of the first annular block 2012, and an upper welding head 2023 installed on the inner wall of the second annular block 2022, wherein both the lower welding head 2013 and the upper welding head 2023 are inclined inward.

[0048] After the frame is fixed, the position of the fixing plate 6 is adjusted so that the welding points of the frame on both sides are aligned with the inside of the welding ring 2. Then, the welding points of the frame are welded simultaneously by the lower welding head 2013 and the upper welding head 2023, which speeds up the welding efficiency. At the same time, both the lower welding head 2013 and the upper welding head 2023 are tilted inward so that the corresponding welding points of the lower welding head 2013 and the upper welding head 2023 are kept on the same vertical plane, avoiding misalignment of the welding points of the lower welding head 2013 and the upper welding head 2023, which would affect the welding effect.

[0049] The outer walls of the first annular block 2012 and the second annular block 2022 are both provided with teeth. The welding ring 2 has a lower equipment groove 203 that communicates with the first annular groove 201. A second servo motor 207 is installed inside the lower equipment groove 203. A lower gear 208 that meshes with the first annular block 2012 is driven and connected to one side of the second servo motor 207. An upper equipment groove 204 that communicates with the second annular groove 202 is opened inside the welding ring 2. A first servo motor 205 is installed inside the upper equipment groove 204. An upper gear 206 that meshes with the second annular block 2022 is driven and connected to one side of the first servo motor 205.

[0050] During the welding process, the first servo motor 205 drives the upper gear 206 to rotate, and the upper gear 206 meshes with the second annular block 2022, thereby driving the second annular block 2022 to rotate within the second annular groove 202. This causes the upper welding head 2023 to rotate along the second limiting groove 2021, thus performing welding on the weld seam on the upper surface of the frame. Meanwhile, the second servo motor 207 drives the lower gear 208 to rotate, and the lower gear 208 meshes with the first annular block 2012, thereby driving the first annular block 2012 to rotate within the first annular groove 201. This causes the lower welding head 2013 to rotate along the first limiting groove 2011, performing welding on the weld seam on the lower surface of the frame. Since the curvature of both the first limiting groove 2011 and the second limiting groove 2021 is greater than 180°, this ensures that the upper welding head 2023 and the lower welding head 2013 can perform welding operations on the periphery of the frame weld seam from all directions.
