Description

Technical Field

[0001] The present invention relates to the technical field of welding tooling, and specifically to an ultrasonic welding tooling for the processing of a central passage body assembly. Background Art

[0002] The ultrasonic welding tooling for the processing of a central passage body assembly is a special equipment dedicated to the automated welding of automotive central passage components. Its core design includes a multi-station material transfer system, a detachable positioning and clamping module, and a welding head unit. The welding assembly uses a robotic arm to carry the ultrasonic welding head unit and is suitable for complex components such as central passages with large sizes and many welding points.

[0003] In the prior art, when performing the ultrasonic welding process on an automotive central passage assembly, due to the large number of positioning buckles and corners in the general assembly, a large amount of time is required to confirm before processing, and then welding can be carried out. Moreover, when taking it, it is easy to make mistakes with the just-installed card feet, so repeated confirmation is needed, wasting a large amount of time and affecting the processing efficiency. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide an ultrasonic welding tooling for the processing of a central passage body assembly, so as to solve the technical problems that a large amount of time is required to confirm before processing and then welding can be carried out, and when taking it, it is easy to make mistakes with the just-installed card feet, so repeated confirmation is needed, wasting a large amount of time and affecting the processing efficiency.

[0005] To achieve the above object, the present invention provides the following technical solution: An ultrasonic welding tooling for the processing of a central passage body assembly, including a die bottom plate and a backing plate. The top of the die bottom plate is fixedly connected to the backing plate through multiple groups of support plates. The top of the backing plate is fixedly connected with a first pressing mechanism, and one end of the top of the backing plate is fixedly connected with a second pressing mechanism. The first pressing mechanism and the second pressing mechanism press the outer surface of the central passage body. One end of the die bottom plate is fixedly connected with a third pressing mechanism, and the other end of the die bottom plate is fixedly connected with two groups of fourth pressing mechanisms. The two ends of the die bottom plate are respectively fixedly connected with a first fixing mechanism and a second fixing mechanism, and the first fixing mechanism is located on one side of the third pressing mechanism, and the second fixing mechanism is located between the two groups of fourth pressing mechanisms. Two groups of third fixing mechanisms and fourth fixing mechanisms are respectively fixedly connected to both sides of the top of the backing plate. A first positioning support and a second positioning support are fixedly connected between the die bottom plate and the backing plate. Two groups of third positioning supports are fixedly connected to the top of the backing plate, and the two groups of third positioning supports are located on both sides of the second pressing mechanism. Two groups of fourth positioning supports are fixedly connected to one end of the top of the backing plate.

[0006] By adopting the above technical solution, the present invention realizes the precise pre-positioning of the positions of the components of the central channel body through the coordinated action of multiple groups of positioning and supporting and pneumatic pressing mechanisms and the hierarchical positioning structure on the die bottom plate and the backing plate. Combining with the multi-angle pressing system formed by the rotating cylinder driving the connecting rod, the movable rod and the pressing block, it can synchronously complete the adaptive clamping of the surface, inside and both ends of the component, effectively preventing displacement or misalignment caused by vibration during the welding process. The slide rail type fixing mechanism equipped with the tooling further strengthens the stability of the component. By controlling the fixed blocks to move towards each other through the pneumatic slider, multi-point dynamic locking is formed, which not only realizes the rapid response and one-time precise positioning of the clamping process, but also ensures the operation safety through the external safety protection device, solves the problems of repeatedly adjusting the component position and easy loosening of the clamping feet in traditional welding, greatly shortens the clamping confirmation time, avoids rework, is especially suitable for the automatic welding scenario of multi-weld point and large-size complex components, and significantly improves the production rhythm and the qualified product rate.

[0009] By adopting the above technical solution, when the first pressing cylinder in the first pressing mechanism is started, the rotating rod will move up and down and rotate at the same time, so that the first pressing block can press the central channel body. When the second pressing mechanism is started, the second pressing cylinder therein will drive the lifting block to move up and down, thereby controlling the movement of multiple groups of connecting rods through the rotating shaft, and further enabling multiple groups of second pressing blocks to open and close, realizing the pressing of the internal components of the central channel body.

The first fixing mechanism is located on one side of the third pressing mechanism. However, after the first fixing cylinder is activated, it will drive the first fixing block to clamp the central channel body assembly. The second fixing mechanism is located in the middle of the two groups of fourth pressing mechanisms. When the second fixing cylinder is activated, it will drive the second fixing block to clamp the central channel body. The first fixing block and the second fixing block move towards each other, so as to realize the fixation of the central channel body.

[0014] Further, the third fixing mechanism includes a third fixing cylinder, a first movable plate, a slider, a slide rail and multiple groups of third fixing blocks.

Two groups of fourth fixing mechanisms are installed on both sides of the other end of the backing plate. After the fourth fixing cylinder is activated, it will drive the second movable plate to control one end of the fourth fixing block, so as to fix the central channel body.

[0045] The working principle of the present invention is as follows: When in use, first, the overall tooling can be moved through the handle 17, and can be fixed on the processing workbench through the positioning grooves 15 and the left-right locking positioning blocks 16, which is convenient for the robotic arm to control the welding unit to weld the central channel body assembly;

[0046] After the mold is fixed, multiple components of the central channel body can be placed on the mold bottom plate 1 and the backing plate 2.

When the third fixing cylinder 901 is started, it will drive the first movable plate 902 to slide on the slide rail 904 through the slider 903, so as to drive multiple sets of third fixing blocks 905 to move, and then fix the central channel body;

[0053] Two sets of fourth fixing mechanisms 10 are installed on both sides of the other end of the backing plate 2. After the fourth fixing cylinder 1001 is started, it will drive the second movable plate 1002 to control one end of the fourth fixing block 1003, so as to fix the central channel body;

[0054] Multiple sets of pressing mechanisms and fixing mechanisms fix each component of the central channel body through pneumatic means, enabling quick clamping and fixing of each component. Moreover, multiple sets of positioning supports can determine the positions of each component, ensuring that each component will not move easily and avoiding the situation where each component is misaligned during clamping and fixing.

[0055] Meanwhile, safety measures are also installed outside the mold bottom plate to ensure that operators will not be harmed when the robotic arm welds the central channel body assembly.

[0056] Through the above structure, the technical problems are solved that a large amount of time is required for confirmation before processing and then welding can be carried out, and when taking and placing, it is easy for the just-installed feet to be misaligned, thus requiring repeated confirmation, wasting a large amount of time and affecting the processing efficiency.
