Description

Technical Field

[0001] This utility model relates to the technical field of chassis parts welding devices, and in particular to a pickup truck chassis parts welding device. Background Technology

[0002] As the core load-bearing structure of a pickup truck, its strength and durability directly affect the vehicle's safety and versatility. Because pickup trucks are often used for heavy-duty transport, off-roading, or engineering work, the chassis is subjected to complex stresses over long periods, making it prone to problems such as beam deformation, weld cracking, or metal fatigue. These issues require repair or reinforcement through welding. In modification scenarios, users may install accessories such as roll cages, tow plates, or tow hooks, all of which need to be rigidly connected to the chassis through welding to ensure stability. During the manufacturing stage, the chassis is assembled from multiple steel components (such as longitudinal beams, cross beams, and suspension brackets), and welding is a key process to ensure structural integration. Whether in repair or production, welding quality directly affects the chassis's torsional rigidity, load distribution, and long-term reliability.

[0003] However, existing technologies have some problems: In traditional pickup truck chassis welding operations, workers usually need to operate the welding gun in the narrow space under the vehicle while also taking care of the positioning and fixing of multiple scattered fixtures. This not only puts workers in an inconvenient working posture and makes them prone to fatigue, but also makes it difficult to guarantee positioning accuracy and welding efficiency due to the lack of coordination between fixtures. Therefore, we propose a welding device for pickup truck chassis parts. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a welding device for pickup truck chassis parts. By setting up a liftable receiving platform and clamping components, the device uses adjustable angle and range components to clamp and fix the structure of the pickup truck chassis to be welded, improving the positioning accuracy of the welding part, reducing the labor intensity of workers, and increasing work efficiency.

[0005] The purpose of this utility model is achieved as follows: a welding device for pickup truck chassis parts includes a connecting seat, two connecting rods rotatably connected to the lower end of the connecting seat, a limit assembly provided between the connecting rods and the connecting seat for adjusting and fixing the rotation angle, a support foot hinged to the connecting rod, a handle rotatably connected to the connecting seat, a screw threadedly connected to the handle, a receiving platform provided on the screw, a clamping assembly provided on the receiving platform, and the clamping assembly adjusting the clamping range by rotation and extension.

[0006] Optionally, the connecting rod is provided with teeth, the connecting seat is provided with grooves, the teeth are inserted into the grooves, and a limit rod is threadedly connected to the connecting seat, the limit rod is in contact with the connecting rod.

[0007] Optionally, the receiving platform is rotatably connected to the screw, and a connecting member is provided at the lower end of the receiving platform.

[0008] Optionally, the clamping assembly includes a cantilever and a clamping body. One end of the cantilever is rotatably connected to a connector, and the other end of the cantilever is slidably connected to the clamping body. A sleeve is rotatably connected to the outer side of the cantilever, and the sleeve is threadedly connected to the clamping body.

[0009] Optionally, the clamping body is provided with a gripper, and a rotating component is provided between the gripper and the clamping body for adjusting the gripping angle of the gripper.

[0010] Optionally, the rotating assembly includes a rotating seat, which is connected to the gripper by a universal ball joint. The rotating seat has a sliding groove, and the gripper has a recess. A spring is provided in the sliding groove, one end of the spring is fixedly connected to the sliding groove, and the other end of the spring is fixedly connected to a limiting pin. The limiting pin contacts the recess.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By setting up a receiving platform and clamping components, the toothed meshing structure of the connecting rod and the connecting seat, together with the limiting rod, enables the chassis support to be quickly positioned and locked. This eliminates the need for workers to repeatedly adjust multiple independent clamps. The threaded transmission mechanism of the cantilever and sleeve allows the clamp to move precisely along the slide rail. Combined with the universal ball joint gripper, it can adapt to welded parts of various angles, improve positioning accuracy, avoid the cumulative errors caused by the dispersion of clamps in traditional operations, and reduce the difficulty of single-person operation, thereby improving work efficiency.

[0012] 2. The rotating connection structure between the receiving platform and the screw allows the entire clamping assembly to be adjusted in space, adapting to a certain range of operations. The adaptive angle adjustment function of the grippers, combined with the spring buffer limit mechanism, eliminates the need for workers to frequently enter the narrow space under the vehicle to manually correct the position of the clamps. This not only improves the worker's working posture and reduces fatigue-inducing movements such as bending over and crouching, but also enables multi-clamp linkage operation, which improves welding efficiency while significantly reducing labor intensity.

[0021] 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.

[0022] like Figures 1 to 6 The pickup truck chassis parts welding device shown includes a connecting seat 1. Two connecting rods 11 are rotatably connected to the lower end of the connecting seat 1. A limit assembly 2 is provided between the connecting rods 11 and the connecting seat 1 for adjusting and fixing the rotation angle. A support leg 12 is hinged to the connecting rod 11. A handle 13 is rotatably connected to the connecting seat 1. A screw 14 is threaded onto the handle 13. A receiving platform 3 is provided on the screw 14. A clamping assembly 4 is provided on the receiving platform 3. The clamping assembly 4 adjusts the clamping range by rotating and extending.

[0023] Furthermore, the use of adjustable support legs 12 and limiting components 2 enables the device to adapt to different terrains or work surfaces, ensuring overall stability during welding. The lifting receiving platform 3, in conjunction with the clamping components 4, allows for adjustment of the height and angle of the welding components, improving positioning accuracy. Through the extension and retraction of the cantilever 41 and the drive of the sleeve 43, it can be matched with chassis parts of different sizes, reducing changeover time.

[0024] Specifically, the connecting rod 11 is provided with teeth 21, the connecting seat 1 is provided with teeth 22, the teeth 21 and the teeth 22 are inserted into each other, and the connecting seat 1 is threadedly connected with a limit rod 23, which contacts the connecting rod 11.

[0025] Furthermore, the interlocking connection enables precise positioning of the connecting rod 11 after angle adjustment, ensuring that the support leg 12 can be quickly locked in the preset position after unfolding, thus enhancing the stability of the overall structure.

[0026] The threaded connection of the limit rod 23 provides mechanical locking force to prevent accidental displacement caused by vibration during welding, while retaining the convenience of quick adjustment; The multi-position structure of the toothed 21 allows the support leg 12 to adapt to different tilt angle support requirements without the need for complicated auxiliary tools. At the same time, the toothed 21 can provide a large meshing force to prevent the connecting rod 11 from shifting at an angle due to force.

[0027] Specifically, the receiving platform 3 is rotatably connected to the screw 14. The lower end of the receiving platform 3 is provided with a connecting piece 31. The clamping assembly 4 includes a cantilever 41 and a clamping body 42. One end of the cantilever 41 is rotatably connected to the connecting piece 31, and the other end of the cantilever 41 is slidably connected to the clamping body 42. A sleeve 43 is rotatably connected to the outer side of the cantilever 41. The sleeve 43 is threadedly connected to the clamping body 42. The clamping body 42 is provided with a gripper 44.

[0028] Furthermore, the stepless sliding adjustment of the clamp body 42 is achieved through the cooperation of the sleeve 43 and the cantilever 41, so that the gripper 44 can accurately position the workpiece at the optimal clamping position; the threaded drive ensures the smooth movement and self-locking of the clamp body 42, avoiding accidental loosening during the welding process; the rotational connection between the cantilever 41 and the receiving platform 3 allows the clamping assembly 4 to be adjusted at multiple angles to adapt to welding requirements in different spatial positions.

[0029] Specifically, a rotating assembly 5 is provided between the gripper 44 and the gripper body 42 to adjust the gripping angle of the gripper 44. The rotating assembly 5 includes a rotating seat 51, which is connected to the gripper 44 by a universal ball joint. A sliding groove 52 is provided on the rotating seat 51, and a groove 53 is provided on the gripper body 42. A spring 54 is provided in the sliding groove 52. One end of the spring 54 is fixedly connected to the sliding groove 52, and the other end of the spring 54 is fixedly connected to a limiting pin 55. The limiting pin 55 contacts the groove 53.

[0030] Furthermore, the rotating assembly 5 uses a universal ball joint structure to enable the gripper 44 to have multi-degree-of-freedom adjustment capability, allowing the gripper 44 to adaptively conform to the workpiece surface with different contours. When the clamping angle is adjusted, the gripper 44 drives the rotating seat 51 to deflect, and the limiting pin 55 in the slide groove 52 slides inward under force, compressing the spring 54. After the angle is rotated, the spring 54 returns to its original position and automatically pushes out the limiting pin 55, which then pushes it into the groove 53. During the workflow, the operator only needs to push the gripper 44 toward the workpiece, and the universal ball joint will automatically adjust the angle. The pressure of the spring 54 ensures stable contact, and the limit pin 55 cooperates with the groove 53 to prevent over-rotation.

[0031] Working principle: First, rotate the limiting rod 23 to release the limiting of the connecting rod 11, disengaging the toothed 21 from the toothed groove 22. Rotate the connecting rod 11 to bring the lower end of the connecting rod 11 into contact with the ground or support surface. Then, engage the toothed 21 with the toothed groove 22, tighten the limiting rod 23, rotate the handle 13, and adjust the receiving platform 3 to a suitable height through the screw 14 to hold the part to be welded. Rotate the sleeve 43 to drive the clamp body 42 to slide along the cantilever 41 to the vicinity of the workpiece. The jaws 44 approach and fit the contour of the part through the universal ball joint and clamp it. Finally, perform the welding operation. After completion, reverse the operation to release the workpiece.

[0032] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
