Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a weld fixing device for a rotatable automobile frame assembly. Background Technique

[0002] The welding of an automobile frame assembly refers to the process of connecting the various components of the automobile frame into a whole through a welding process. The automobile frame is the main load-bearing structure of the automobile. It supports all the components and passengers of the automobile and bears various forces and torques from the road surface and the power system. During the welding process of the automobile frame assembly, common welding methods include, but are not limited to, resistance welding (such as spot welding, multi-spot welding), arc welding (such as shielded metal arc welding, CO2 gas shielded welding, tungsten inert gas welding, etc.), laser welding, ultrasonic welding, etc. These methods have their own characteristics and are suitable for different welding requirements and materials.

[0003] In the prior art, a rotatable weld fixing device for an automobile frame assembly with the publication number of "CN217344264U" includes a movable first base, a lifting table and a bracket. An elevating assembly is arranged on the upper surface of the movable first base. The lifting table is installed above the movable first base through the elevating assembly. An adjusting assembly is arranged on the upper surface of the lifting table. Two groups of brackets are symmetrically arranged above the lifting table through the adjusting assembly. Rotating shafts are rotatably installed on the inner sides of the ends of the brackets, and rotating discs are fixedly sleeved on the ends of the rotating shafts. Through the above technical solution, the height of the whole device is adjusted to meet the needs of welding processing. At the same time, when the driving motor works, the output end thereof will drive the main gear to rotate. Combining the meshing transmission effect of the main gear and the driven gear, the rotating shaft and the rotating disc on one side can be driven to rotate, so as to realize the turning effect of the workpiece and facilitate the welding processing of the welding parts at different positions on the surface of the workpiece.

[0004] However, there are still great deficiencies in the prior art, such as:

[0005] In the prior art, in order to realize the turning of the frame fixture, a worm and worm gear mechanism is often adopted to increase the torque during rotation. However, there is a serious phenomenon of heat generation at the meshing position of the worm and worm gear. Therefore, a device capable of cooling the worm and worm gear during turning is needed. Summary of the Utility Model

[0006] The purpose of the present utility model is to provide a rotatable weld fixing device for an automobile frame assembly to solve the problems raised in the above background technique.

[0007] To achieve the above purpose, the present utility model provides the following technical solutions:

[0012] When the driving motor rotates, through the worm gear ring and the worm, while driving the first connecting plate to rotate to realize the flipping of the welding table, the rotating shaft drives the blower wheel to rotate at a high speed, generating an air flow in the blower box, and the air flow blows to the meshing part of the worm gear ring and the worm through the duct to cool the meshing part of the worm gear ring and the worm;

[0013] Preferably, a second support platform is further fixedly arranged on the first base, a shaft seat is fixedly arranged on the second support platform, a second connecting plate is fixedly arranged on the other side of the welding table, a support shaft is fixedly arranged on the second connecting plate, and the support shaft is rotatably arranged in the shaft seat.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-5 , the present invention provides a technical solution:

[0029] Embodiment 1:

[0030] A welding and fixing device for a reversible automobile frame assembly. First, the basic part of the device is a solid and stable first base 1, which is made of high-quality steel to ensure that it can withstand various stresses without deformation during the welding process. A first support platform 2 is fixedly installed on the first base 1. The first support platform 2 provides accurate planar positioning for the subsequent installation of the reduction box 3, ensuring the stability and accuracy of the transmission system. The first support platform 2 is fixed at the center of the top of the first base 1 by welding or bolt connection, and is designed with sufficient strength and stiffness to support the subsequent components.

[0031] The reduction box 3 is one of the core components of the entire device. The reduction box 3 is fixed on the top of the first support platform 2 by bolt connection or welding to ensure its stability and position accuracy during operation. A worm gear ring 4 and a worm 5 that mesh with each other are rotatably arranged in the reduction box 3. One end of the support frame 6 is connected to the fixed part of the worm gear ring 4, and the other end is connected to the first connecting plate 7 by bolts or other fasteners. The design of the support frame 6 needs to consider its rigidity and stability to bear the weight of the welding table 8, the fixture 9 thereon and the frame assembly. One end of the worm gear ring 4 is closely connected to the first connecting plate 7 through the support frame 6, and a welding table 8 is fixedly installed on the first connecting plate 7.

[0032] On the welding table 8, a plurality of fixtures 9 are distributed, which are customized according to the shape and size of the frame assembly. These fixtures 9 are made of high-strength materials and are equipped with quick-locking mechanisms, which can quickly and accurately clamp the frame to ensure the stability and accuracy during the welding process. These fixtures 9 are fixed on the welding table 8 by bolts or other means for precisely clamping the frame assembly. The design of the fixture 9 needs to consider its clamping force and adjustment range to adapt to frame assemblies of different shapes and sizes. The positions and specifications of the fixtures 9 are arranged according to specific situations and will not be elaborated here.

[0033] To drive the flipping of the welding table 8, a high-performance drive motor 10 is installed at one end of the reduction gearbox 3. The drive motor 10 is fixed to one side of the reduction gearbox 3 through a motor bracket. A rotating shaft 11 is fixedly arranged on the shaft of the drive motor 10, and the rotating shaft 11 is connected to the worm 5 through a spline. When the drive motor 10 starts, the rotating shaft 11 drives the worm 5 to rotate, and then drives the welding table 8 to flip through the meshing of the worm gear ring 4 and the worm 5.

[0034] Embodiment 2:

[0035] Considering the heat problem that may occur when the worm gear ring 4 and the worm 5 operate under high load for a long time, an air-cooling component 12 is specially designed for cooling. The air-cooling component 12 includes a blower box 13 fixed to one side of the reduction gearbox 3. The blower box 13 is fixed to one side of the reduction gearbox 3 by bolts or welding. The blower wheel 14 is rotatably installed in the blower box 13, and the rotating shaft 11 is fixedly connected to the blower wheel 14.

[0036] When the drive motor 10 rotates, the rotating shaft 11 not only drives the worm 5 but also synchronously drives the blower wheel 14 to rotate. The high-speed rotation of the blower wheel 14 generates a strong air flow in the blower box 13. The reduction gearbox 3 is provided with a heat dissipation groove 15 at the position where the worm gear ring 4 and the worm 5 are meshed. A duct 16 is fixedly connected between the air outlet of the blower box 13 and the heat dissipation groove 15. The air flow is guided to the meshing position of the worm gear ring 4 and the worm 5 through the duct 16 for effective cooling treatment. This design not only extends the service life of the transmission system but also improves the working efficiency and stability of the entire device.

[0037] To enhance the stability of the welding table 8 and the smoothness of flipping, a second support platform 17 is additionally provided on the first base 1. A shaft seat 18 is fixedly installed on the second support platform 17. A second connecting plate 19 is arranged on the other side of the welding table 8, and a support shaft 20 is fixedly arranged on the second connecting plate 19. The support shaft 20 is rotatably arranged in the shaft seat 18, forming a multi-point support structure with the first connecting plate 7. This double-support design not only enhances the rigidity of the welding table 8 but also makes the flipping action more stable and reliable.

[0038] At the same time, to increase the side wall strength of the reduction gearbox, a reinforcing rib plate 21 is fixedly installed on its side wall. The presence of the reinforcing rib plate 21 effectively improves the anti-deformation ability of the reduction gearbox, making the entire transmission system more robust and durable.

[0039] To accommodate various working environments, a second base 22 is designed at the bottom of the first base 1. The first base 1 is rotatably mounted on the second base 22. Several fixing plates 23 are fixedly mounted on the second base 22, and adjustment bolts 24 are rotatably mounted on the fixing plates 23. Support pads 25 are rotatably mounted on the adjustment bolts 24, allowing for height adjustment as needed. Furthermore, several support legs 26 are provided on the second base 22, each with an adjustment slot 27. By using the adjustment slots 27 in conjunction with positioning bolts 28, the support legs 26 can be securely fixed to the second base 22, allowing the horizontal position and stability of the entire device to be adjusted as needed.

[0040] Working Principle: During the use of the present invention, the automobile frame assembly to be welded is placed on the welding table 8 and is precisely clamped using the clamp 9. The design of the clamp 9 ensures that the frame remains stable during the welding process and does not move or deform.

[0041] The position and clamping force of the clamp 9 can be adjusted to accommodate vehicle frame assemblies of different shapes and sizes.

[0042] When the welding needs to be turned over, the power is turned on and the drive motor 10 is started. The drive motor 10 is fixed to one side of the reduction box 3 through a motor bracket, and the rotating shaft 11 fixedly arranged on the shaft starts to rotate.

[0043] The rotating shaft 11 is connected to the worm 5 via a spline, so when the rotating shaft 11 rotates, the worm 5 also rotates.

[0044] The worm 5 and the worm gear ring 4 are meshed with each other in the reduction box 3 , and the rotation of the worm 5 drives the worm gear ring 4 to rotate.

[0045] One end of the worm gear ring 4 is tightly connected to the first connecting plate 7 via the support frame 6 , so the rotation of the worm gear ring 4 drives the first connecting plate 7 and the welding platform 8 to turn over synchronously.

[0046] During the turning process of the welding table 8 , the frame assembly is kept in a stable state in the fixture 9 , thereby allowing the welder to weld the frame from different angles.

[0047] When the driving motor 10 is started, the rotating shaft 11 not only drives the worm 5 but also drives the fan wheel 14 to rotate.

[0048] The fan wheel 14 rotates at high speed in the fan box 13, generating a strong airflow. The airflow is guided to the meshing part of the worm ring 4 and the worm 5 through the air guide 16, and is effectively cooled.

[0049] This process helps reduce heat buildup in the transmission system, extending its service life and improving the operating efficiency and stability of the entire unit.

[0050] If it is necessary to adjust the height or horizontal position of the device, the adjusting bolts 24 and the support pads 25 on the second base 22 can be operated. By rotating the adjusting bolts 24, the height of the support pads 25 can be changed, thereby adjusting the position of the entire device.

[0051] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
