Description

Technical Field

[0001] This utility model relates to the field of welding tooling technology, specifically to an integrated tooling assembly for welding a vehicle frame and a side beam. Background Technology

[0002] In the automotive manufacturing and construction machinery industries, the side beam assembly of the chassis is a core component that bears the weight of the entire vehicle, transmits power, and ensures structural stability. Its welding precision and assembly quality directly determine the safety performance and service life of the entire vehicle. To meet the welding process requirements of the side beam assembly, the industry commonly uses specialized tooling assemblies to fix and limit the side beam assembly, ensuring that the workpiece will not shift due to external forces or thermal deformation during the welding process, thereby guaranteeing the strength and dimensional accuracy of the welded joint.

[0003] Existing integrated welding fixtures for vehicle frame side beams typically employ a symmetrical, left-right fixing design. This involves using simple clamping or abutment mechanisms on both sides of the fixture support to position the side beam assembly from left to right before welding. However, this traditional fixing method has certain technical drawbacks: On the one hand, it can only achieve rough horizontal positioning of the side beam assembly, and cannot effectively constrain the top surface, side surface and key assembly parts of the side beam assembly. During the welding process, the workpiece is prone to warping and displacement due to thermal stress, resulting in the overall dimensions of the side beam assembly exceeding the tolerance. Additional correction is required during subsequent assembly, which seriously affects production efficiency. On the other hand, the fixing structure of traditional tooling is mostly rigid connection, which lacks adaptability to the complex structure of the side beam assembly. For side beam assemblies with special structures such as hollow holes and anti-fool shafts, the fixing stability is even worse. This not only easily causes damage to the surface of the workpiece, but may also cause misalignment of the welded joint due to positioning deviation, reducing the overall load-bearing capacity of the frame.

[0004] With the increasing demands for lightweight and high strength in automobiles and construction machinery, the structural design of the frame side beam assembly is becoming increasingly complex. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a tooling assembly for welding the frame and side beams together.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A tooling assembly for welding a vehicle frame and side beams together includes: a tooling bracket, a reducer and a bearing housing respectively mounted on the top of the left and right sides of the tooling bracket, a turntable handle mounted on the front side of the reducer, a rotating chassis movably mounted between the reducer and the bearing housing, fixed brackets mounted on the left and right sides of the top of the rotating chassis, multiple sets of clamping assemblies mounted on the front of the top of the rotating chassis, symmetrical support shaft assemblies mounted on the left and right sides of the front of the top of the rotating chassis, and multiple sets of positioning assemblies mounted on the rear of the top of the rotating chassis. The clamping assemblies are used to press and fix the top and side surfaces of the side beam assembly with bolts, the positioning assemblies are used to position the L-shaped plate on the rear side of the side beam assembly, and the support shaft assemblies are used to support and limit the axle pins on the front side of the side beam assembly.

[0007] Preferably, the positioning component includes: a support column one, which is fixed to the rotating chassis by bolts; a rotating shaft is provided at the top of the support column one; a connecting plate is movably mounted on the rotating shaft; a first bolt tightening handle is sleeved on the connecting plate; a support seat one is fixedly mounted on the top surface of the rotating chassis below the first bolt tightening handle; a support seat two is provided on the left side of the support seat one; a wrench fixing component is fixedly mounted on the top of the support seat two; a support block is provided on the top of the support seat one; the wrench fixing component is used to rotate the wrench to control the extension and retraction of the tightening rod, pressing and fixing the side of the L-shaped plate to the side of the support block; and the first bolt tightening handle is used to rotate the handle to press and fix the top surface of the L-shaped plate between the bottom of the first bolt tightening handle and the top surface of the support block.

[0008] Preferably, the support shaft assembly includes: a second support column, a rotating shaft at the top of the second support column, a connecting plate movably connected to the rotating shaft, a second bolt tightening handle on the connecting plate, and a first support shaft seat and a second support shaft seat respectively on the left and right sides of the front of the second support column. The first support shaft seat and the second support shaft seat are used to support the anti-foolproof shaft on the front side of the limiting side beam assembly, and the second bolt tightening handle is used to rotate the handle to press and fix the anti-foolproof shaft on the support shaft seat.

[0009] Preferably, the fixed bracket includes: a bracket base, which is fixedly connected to the rotating chassis by bolts. The bracket base is provided with a long limiting protrusion and a short limiting protrusion at the front and rear respectively. The long limiting protrusion is used to fix and limit the side beam assembly by entering the hollow hole of the side beam assembly, and the short limiting protrusion is used to contact the side of the side beam assembly to limit the side beam assembly.

[0010] Compared with the prior art, this utility model provides a tooling assembly for welding the frame and side beams together, which has the following advantages: The positioning component can constrain the L-shaped plate on the rear side of the side beam assembly on both sides. The wrench fixing component controls the clamping rod to press the side of the L-shaped plate, while the first bolt clamping handle is used to press and fix the top surface of the L-shaped plate to the support block, so as to achieve precise positioning of the L-shaped plate and prevent the L-shaped plate from flipping or shifting during welding. The support shaft assembly forms a support and limit on the anti-fool shaft on the front side of the side beam assembly through support shaft seat one and support shaft seat two. In conjunction with the second bolt tightening handle, the top surface of the anti-fool shaft is pressed and fixed to ensure that the anti-fool shaft has no axial or radial displacement during the welding process, thus ensuring the accuracy of the front end assembly structure of the side beam assembly. By using positioning components and support shaft components, production efficiency can be improved without interfering with the welding process. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Reference Figures 1-5As shown, this embodiment of a chassis and side beam integrated welding fixture assembly includes a fixture bracket 1. The fixture bracket 1 serves as the basic support component of the entire fixture assembly, providing a stable carrier for the subsequent installation of various functional components. The top of the left and right sides of the fixture bracket 1 are fixedly connected to the reducer 201 and the bearing housing 204, respectively. This fixed connection method ensures that the reducer 201 and the bearing housing 204 will not shift during use, guaranteeing the stable operation of the subsequent rotating structure.

[0015] The front of the reducer 201 is movably connected to the turntable handle 202. By rotating the turntable handle 202, the output speed of the reducer 201 can be adjusted, thereby controlling the rotation speed of the rotating chassis 203 to meet the needs of adjusting the workpiece angle in different welding scenarios. The reducer 201 and the bearing housing 204 are movably connected to the rotating chassis 203. This movable connection allows the rotating chassis 203 to rotate flexibly around the axis formed by the reducer 201 and the bearing housing 204, facilitating welding operations of the side beam assembly 7 at different angles by the welder.

[0016] The top left and right sides of the rotating chassis 203 are fixedly connected to the fixed brackets 3 by bolts. This bolt connection allows for flexible adjustment of the fixed brackets 3 according to the specifications of the side beam assembly 7, improving the adaptability of the tooling. Multiple sets of clamping components 4 are provided on the front top of the rotating chassis 203. The distribution of these components provides uniform pressure on the top and sides of the side beam assembly 7, ensuring a secure fixation. The top front left and right sides of the rotating chassis 203 are symmetrically fixedly connected to the support shaft components 5. These symmetrically distributed support shaft components 5 provide stable support for the anti-foolproof shaft 702 on the front side of the side beam assembly 7, preventing positioning deviations caused by unilateral force. Multiple sets of positioning components 6 are provided on the rear top of the rotating chassis 203. These components provide multi-point positioning of the L-shaped plate 701 on the rear side of the side beam assembly 7, further enhancing the stability of the side beam assembly 7.

[0017] Positioning component 6 includes a first support column 601, which is fixed to the rotating base 203 by bolts. Bolting facilitates the disassembly, assembly, and position adjustment of the first support column 601. A rotating shaft is located at the top of the first support column 601, and a connecting plate is movably connected to the shaft. This movable connection allows the connecting plate to rotate flexibly around the shaft, facilitating adjustment of the pressing angle of the first bolt tightening handle 604. The first bolt tightening handle 604 is fitted onto the connecting plate. The top surface of the rotating base 203 below the first bolt tightening handle 604 is fixedly connected to a first support base 603. The left side of the first support base 603 is fixedly connected to a second support base 602. The top of the second support base 602 is fixedly connected to a wrench fixing component 403. A support block is located at the top of the first support base 603. The wrench fixing part 403 controls the extension and retraction of the clamping rod by rotating the wrench, which can press and fix the side of the L-shaped plate 701 to the side of the support block; the first bolt clamping handle 604 can press and fix the top surface of the L-shaped plate 701 between the bottom of the first bolt clamping handle 604 and the top surface of the support block by rotating the handle, thus realizing the double-sided constraint of the L-shaped plate 701.

[0018] The support shaft assembly 5 includes a second support column 501. A rotating shaft is provided at the top of the second support column 501, and the rotating shaft is movably connected to a connecting plate. A second bolt tightening handle 504 is fitted on the connecting plate. The front left and right sides of the second support column 501 are fixedly connected to the first support shaft seat 502 and the second support shaft seat 503, respectively. The first support shaft seat 502 and the second support shaft seat 503 can support and limit the anti-foolproof shaft 702 on the front side of the side beam assembly 7. The second bolt tightening handle 504 presses and fixes the anti-foolproof shaft 702 on the support shaft seat by rotating the handle, ensuring that the anti-foolproof shaft 702 has no axial or radial displacement.

[0019] The fixed bracket 3 includes a bracket base 3, which is fixedly connected to the rotating chassis 203 by bolts. The bracket base 3 is provided with a long limiting protrusion 301 and a short limiting protrusion 302 at the front and rear, respectively. The long limiting protrusion 301 can enter the hollow hole of the side beam assembly 7 for fixed limiting, and the short limiting protrusion 302 can contact the side of the side beam assembly 7, providing double limiting for the side beam assembly 7 and further improving the fixed stability of the side beam assembly 7.

[0020] In some examples, wear-resistant shims are provided at the connection between the reducer 201 and the rotating chassis 203. The wear-resistant shims can reduce the frictional loss between the reducer 201 and the rotating chassis 203, extend the service life of both, and at the same time ensure the smooth rotation of the rotating chassis 203, avoiding rotation jamming caused by excessive frictional resistance.

[0021] The working principle of this utility model is as follows: When using this integrated welding fixture assembly for the side beams of the vehicle frame, firstly, based on the specifications and dimensions of the side beam assembly 7 and the welding operation scenario, a flat and easy-to-operate installation area should be selected, and the fixture bracket 1 should be placed stably. The rigid structure of the fixture bracket 1 should be used to ensure the basic stability of the entire fixture assembly.

[0022] Next, pre-adjustment and inspection of the tooling components are carried out: confirm that the reducer 201 and bearing housing 204 are firmly fixed on the top of the left and right sides of the tooling bracket 1, and rotate the turntable handle 202 to test the rotation flexibility of the rotating base 203. The rotating base 203 should be able to rotate smoothly around the axis formed by the reducer 201 and bearing housing 204 without jamming or offset. According to the position of the hollow hole and the side dimension of the side beam group 7, adjust the installation position of the fixing bracket 3 on the top left and right sides of the rotating base 203 by bolts to ensure that the long limiting protrusion 301 on the fixing bracket 3 can accurately correspond to the hollow hole of the side beam group 7, and the short limiting protrusion 302 can fit with the side of the side beam group 7, so as to prepare for the subsequent workpiece limiting.

[0023] Then, the positioning and fixing of the side beam assembly 7 is carried out: the side beam assembly 7 is placed stably on the top of the rotating chassis 203, so that the L-shaped plate 701 on the rear side of the side beam assembly 7 corresponds to the support seat 603 of the positioning component 6, and the anti-foolproof shaft 702 on the front side corresponds to the support shaft seat 502 and the support shaft seat 503 of the support shaft assembly 5. First, operate the fixed bracket 3 to complete the initial limiting, allowing the long limiting protrusion 301 to be inserted into the hollow hole of the side beam assembly 7, and the short limiting protrusion 302 to be in close contact with the side of the side beam assembly 7, restricting the horizontal movement of the side beam assembly 7; next, fix the anti-foolproof shaft 702 on the front side of the side beam assembly 7: place the anti-foolproof shaft 702 in the groove of the first support shaft seat 502 and the second support shaft seat 503, rotate the connecting plate around the rotating shaft at the top of the second support column 501, so that the second bolt tightening handle 504 is aligned with the top surface of the anti-foolproof shaft 702, rotate the second bolt tightening handle 504, and fix the anti-foolproof shaft 702 on the support shaft seat by pressing the bolt, ensuring that the anti-foolproof shaft 702 has no axial or radial displacement; then fix the L-shaped plate 701 on the rear side of the side beam assembly 7: first rotate the support... The wrench fixing part 403 on the top of the support 602 controls the extension and retraction of the clamping rod, pressing the side of the L-shaped plate 701 against the side of the support block on the top of the support 603 to achieve side limiting; then, the connecting plate is rotated around the pivot on the top of the support column 601, so that the first bolt clamping handle 604 covers the top surface of the L-shaped plate 701. Rotating the first bolt clamping handle 604 presses and fixes the top surface of the L-shaped plate 701 between the bottom of the first bolt clamping handle 604 and the top surface of the support block, completing the double-sided constraint of the L-shaped plate 701; finally, multiple sets of clamping components 4 are activated, pressing the top surface and side of the side beam group 7 with bolts to form an all-round fixing system, preventing the workpiece from shifting due to thermal deformation or vibration during the welding process.

[0024] During the welding operation, the operator can adjust the output speed of the reducer 201 by rotating the turntable handle 202 according to the needs of the welding area. This controls the rotation angle of the rotating chassis 203, causing the side beam assembly 7 to rotate synchronously. This ensures that the area to be welded is always in a position easily accessible to the operator, eliminating the need for frequent workstation changes. During this process, the positioning component 6, support shaft assembly 5, clamping component 4, and fixing bracket 3 all avoid the welding joint area of ​​the side beam assembly 7, preventing obstruction of the welding torch's path and direct contact with welding spatter, thus ensuring smooth welding. Simultaneously, because the side beam assembly 7 achieves precise omnidirectional positioning, the workpiece remains stationary during welding, effectively guaranteeing the strength and dimensional accuracy of the weld joint, reducing subsequent calibration steps, and improving production efficiency.

[0025] If the position of the side beam group 7 needs to be temporarily adjusted during the welding process, the corresponding area's clamping component 4 or bolt clamping handle can be loosened first. After rotating the rotating base 203 to the target angle, the components can be tightened again to restore the fixed state. The operation is convenient and does not affect the overall positioning accuracy.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
