However, existing welding equipment is mostly of a fixed design, making adjustments inconvenient and difficult to quickly adapt to the welding needs of different products, resulting in long production preparation times and poor flexibility. At the same time, when welding at complex angles and positions, ordinary equipment is difficult to operate and prone to welding defects such as porosity and cracks, affecting product quality.

[0004] In order to solve the above-mentioned technical problems, this utility model designs an adjustable cam pump flange automatic welding device. Utility Model Content

[0024] like Figure 1 As shown, an adjustable cam pump flange automatic welding device includes an integral support 1, a rotating assembly 2, and a flange positioning device 8.

[0025] The overall support 1 is provided with a first adjustment component 5, which is slidably connected to a second adjustment component 6. A vertical sliding component 4 is connected to the second adjustment component 6. A welding torch 7 is provided on the vertical sliding component 4. A flange positioning device 8 is slidably provided on the overall support 1. A welding table 3 is rotatably connected to the rotating component 2.

[0026] like Figure 2 and Figure 5As shown, the rotating assembly 2 includes a rotating bracket 21 and a rotating platform 22. The rotating platform 22 is detachably connected to the rotating bracket 21. A rotating motor 23 is fixedly mounted on the rotating platform 22. The output end of the rotating motor 23 is connected to a worm gear 24. A worm wheel 25 and a rotating rod 26 are disposed in the rotating platform 22. The worm wheel 25 meshes with the worm gear 24 and is fixedly connected to the rotating rod 26. A welding platform 3 is connected to the rotating rod 26. Starting the rotating motor 23 drives the worm wheel 25 and the rotating rod 26 to rotate, thereby causing the welding platform 3 to rotate. Using the worm gear mechanism, precise rotation angle control of the welding platform 3 can be achieved. This design enables multi-angle welding operations on the cam pump during the welding process, improving the flexibility and adaptability of the welding process.

[0027] like Figure 3 As shown, the first adjustment component 5 includes a first motor 51 and a first screw 52. The first motor 51 is fixedly connected to the overall bracket 1, and its output end is connected to the first screw 52. The second adjustment component 6 is fitted onto the first screw 52 and threadedly connected to the first screw 52. A first slide rail is fixedly connected to the overall bracket 1, and the second adjustment component 6 is slidably connected to the first slide rail.

[0028] The first motor 51 drives the first screw 52 to rotate, enabling the second adjustment component 6, mounted on the first screw 52, ​​to move precisely along a predetermined trajectory. This design allows for fine-tuning of the welding torch 7 in the x-direction, thereby achieving high-precision welding. This design allows for quick and accurate adjustment of the welding torch position according to different welding requirements, adapting to various complex working conditions and different welding tasks, thus enhancing the equipment's versatility and application range.

[0029] like Figure 4 As shown, the second adjustment component 6 includes a second bracket 60 and a second motor 61. The second motor 61 is fixedly connected to the second bracket 60, and the output end of the second motor 61 is connected to a second screw 62. The vertical sliding component 4 is fitted onto the second screw 62 and threadedly connected to it. The second bracket 60 is provided with a second slide rail, and the vertical sliding component 4 is slidably connected to the second slide rail. The second motor 61 drives the second screw 62 to rotate, allowing the vertical sliding component 4 to move precisely up and down along the second screw 62. This design allows for fine-tuning of the position of the welding torch 7 in the y-axis direction, ensuring high accuracy during the welding process.

[0030] The vertical sliding assembly 4 includes a third motor 41 and a mounting plate 43. The third motor 41 is fixed to the sliding bracket 40, and its output end is connected to a third screw. The mounting plate 43 is fitted onto the third screw and threadedly connected to it. A welding torch 7 is detachably connected to the mounting plate 43. By driving the third screw to rotate through the third motor 41, the mounting plate 43 can move precisely up and down along the third screw. This allows for fine-tuning of the vertical position of the welding torch 7, ensuring high accuracy during the welding process.

[0031] A cam pump positioning device is installed on the welding table 3. The position of the cam pump can be precisely determined by using positioning pins and a set reference surface. This method is simple and effective, suitable for applications requiring high-precision positioning. Alternatively, a positioning fixture, such as a jaw-type fixture, can be used to clamp the outer wall of the cam pump from different directions using multiple adjustable jaws. Such fixtures are readily available to those skilled in the art and will not be described in detail here.

[0032] like Figure 6 As shown, the flange positioning device 8 includes a sliding block 81, a connecting rod 82, and a fixing ring 83. One end of the connecting rod 82 is connected to the sliding block 81, and the other end is detachably connected to the fixing ring 83. An adjusting slide is provided on the overall support 1, and the sliding block 81 slides on the adjusting slide. The sliding block 81 can slide freely on the adjusting slide provided on the overall support 1, which means that the position of the flange positioning device can be quickly and accurately adjusted according to the specific size and position requirements of the flange. This design greatly improves the adaptability of the equipment to workpieces of different specifications. The connecting rod 82 and the fixing ring 83 are detachably connected, making it easy to install and remove the fixing ring 83 and replace it with a fixing ring 83 suitable for flanges of different specifications. When the sliding block 81 slides on the adjusting slide, one or more locking bolts or knobs can be installed on the sliding block 81. After the sliding block is adjusted to the correct position, the slide can be clamped by tightening these bolts or knobs, thereby preventing the sliding block from moving.

[0033] The fixing ring 83 comprises two half-rings connected by bolts. The fixing ring 83 consists of two half-rings connected by bolts, which not only facilitates clamping flanges of different diameters but also allows for adjustment of its opening size as needed, increasing the versatility and flexibility of the flange positioning device.

[0034] The connecting rod 82 is a telescopic rod. The length of the telescopic rod can be adjusted according to actual needs, meaning the flange positioning device can adapt to cam pump flanges of different sizes and shapes. Whether the flange is large or small, adjusting the length of the connecting rod ensures accurate positioning and secure fixing of the flange. Furthermore, the telescopic rod facilitates the positioning, installation, and removal of the retaining ring 83. When it is necessary to install or remove the retaining ring 83, the position of the retaining ring can be changed by adjusting the length of the telescopic rod, making it easier to access the cam pump flange to be welded. During installation, the telescopic rod can be extended to make it easier to align the retaining ring with the flange; during disassembly, the telescopic rod can be shortened appropriately to provide more space for operation.

[0035] In the structural design of the telescopic rod, different segments of the connecting rod 82 can be set as inner and outer tube sleeves, with matching threads machined on the outer wall of the inner tube and the inner wall of the outer tube. When adjusting the length, the relative position of the inner and outer tubes is changed by rotating the inner or outer tube to achieve the required length. After adjustment, the self-locking characteristic of the threads can fix the inner and outer tubes relatively, preventing the telescopic rod from expanding or contracting due to external forces during the welding process.

[0036] This device is suitable for situations where the flange is welded above the cam pump. If welding to the side is required, the direction of the cam pump can be adjusted so that the flange welding end faces upward.

[0037] In use, the cam pump to be welded is positioned and fixed on the welding table 3, and the flange to be welded is fixed on the flange positioning device 8. The sliding block 81 in the flange positioning device 8 slides along the adjusting slide to the appropriate position and is fixed. The connecting rod 82 is used as a telescopic rod to adjust the length to adapt to flanges of different sizes. Finally, the flange is firmly clamped by the fixing ring 83.

[0038] Select a rotating bracket 21 of appropriate height according to the position of the flange and the cam pump to match the height of the flange and the cam pump.

[0039] The position of the welding torch 7 is initially adjusted by adjusting the first adjustment component 5, the second adjustment component 6, and the vertical sliding component 4.

[0040] After the device is started, the first motor 51 drives the first screw 52, ​​which in turn moves the second adjusting component 6 along the x-direction; the second motor 61 drives the second screw 62, which controls the vertical sliding component 4 to move along the y-direction, thereby precisely adjusting the position of the welding torch 7. The third motor 41 further fine-tunes the height of the welding torch to ensure that the welding torch is accurately aligned with the welding point.

[0041] When the rotating motor 23 in the rotating assembly 2 is started, it drives the welding table 3 to rotate through the cooperation of the worm gear 24 and the worm wheel 25, so that different parts of the flange enter the welding range in sequence.

[0042] Once a flange welding is completed, stop all motors, release the flange positioning device 8, remove the welded flange, and then prepare for the next workpiece by repeating the above steps.

[0043] It should be noted that the cam pump positioning device, welding torch 7, fixing ring 83, and telescopic rod in this embodiment are all general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
