Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, specifically relating to a high-pressure gas filling and welding mechanism. Background Technology

[0002] A high-pressure gas filling and welding mechanism is a comprehensive industrial equipment or system that integrates high-pressure gas preparation, storage, transportation and welding operations. It melts the base material and filler material through electric arc, flame or other energy forms to achieve material connection. This mechanism is widely used in manufacturing scenarios with strict requirements for welding quality and gas pressure, such as high-pressure pipelines, pressure vessels, and heavy machinery.

[0015] Compared with the prior art, this utility model provides a high-pressure gas filling and welding mechanism, which has the following beneficial effects:

[0016] 1. The welding mechanism incorporates a mounting block, feeding platform, positioning mechanism, inflatable welding components, high-pressure seals, high-pressure air inlet and outlet, quick-change V-blocks, product position monitoring, product presence / absence detection, mounting base, slots, guide rods, sliding holes, fixing plates, buffer springs, spring limit holes, and spring grooves. The mounting block is positioned on top of the welding mechanism body, and the feeding platform is installed on top of it. This layout integrates the feeding function into the main body of the welding mechanism, reducing the equipment's footprint and creating a compact structure. Simultaneously, the mounting base, through its slots, corresponds to the mounting block, providing a stable foundation for the feeding platform and ensuring overall equipment stability. The quick-change V-blocks on top of the feeding platform allow for rapid adaptation to products of different shapes. The product position monitoring on the left and right sides and the product presence / absence detection on the top provide real-time and accurate monitoring of the product's position. The product placement ensures the product is in the correct processing position, improving processing accuracy and efficiency. A buffer spring array at the bottom of the feeding platform, along with spring limit holes inside the mounting base and spring grooves on the top of the mounting block, effectively buffers vibration during equipment operation, reducing the impact of vibration on product processing accuracy and improving welding and inflation quality. The guide rod engages with sliding holes inside the feeding platform, and its bottom is fixed by a fixing plate, allowing the feeding platform and mounting base to slide smoothly through the guide rod. This ensures smooth sliding during installation and use, facilitating maintenance and adjustment. The inflation welding component on the top of the mounting block, along with the top high-pressure seal and side high-pressure air inlet / outlet, provides a high-pressure inflation environment for the product, meeting specific processing needs and enhancing the equipment's functionality.

[0017] 2. Through the installation of a positioning cylinder, a steel ball blocking mechanism, a clamping cylinder, a buffer sleeve, positioning pins, and limit pins, the positioning cylinder at the top of the positioning mechanism drives the movement of the steel ball blocking mechanism. The steel ball blocking mechanism connects to the gas-inflated welding component, accurately determining the position of the product during the gas-inflated welding process, ensuring consistency in product position during each processing run, thereby improving processing accuracy and product quality stability. The clamping cylinder located behind the steel ball blocking mechanism further clamps and fixes the product after positioning. This combination of positioning and clamping ensures that the product will not shift due to external forces during processing. The positioning mechanism provides a stable working foundation for operations such as high-pressure inflation and welding. The buffer sleeve at the top of the steel ball blocking mechanism and the internal positioning pin play a buffering role during positioning and clamping, which can effectively avoid hard impact on the product during positioning and clamping, and prevent the product from being damaged or deformed due to impact. It is especially suitable for processing impact-sensitive products. The limit pin set on the right side of the positioning cylinder can limit and adjust the stroke of the positioning cylinder. By reasonably adjusting the position of the limit pin, it can adapt to the positioning requirements of different specifications of products, enhance the versatility and flexibility of the positioning mechanism, and make it applicable to the processing and production of a variety of products.

[0035] In this embodiment, the specific implementation steps of a high-pressure inflation and welding mechanism are as follows: The main body 1 of the welding mechanism is placed in a predetermined work site and its stability is ensured. Using suitable connectors such as bolts, the mounting base 29 at the bottom of the feeding platform 2 is firmly fixed to the mounting block 21 through the fixing hole 25 at the top of the mounting block 21. The guide rod 28 is inserted into the sliding hole 32 inside the feeding platform 2, and the bottom of the guide rod 28 is fixed by the fixing plate 30 to form a stable support structure. Simultaneously, the buffer springs 27 arranged in an array at the bottom of the feeding platform 2 are installed in the spring limiting hole 31 inside the mounting base 29 and the spring groove 24 at the top of the mounting block 21 to provide a buffer function for the feeding platform 2. The L-shaped mounting plate 18 at the bottom of the positioning mechanism 3 is then... The bolts are fixedly connected to the base plate 17. Check whether the high-pressure seal 11 on the top of the gas-inflated welding component 7 is properly installed to ensure sealing performance.

At the same time, check the installation of the electrode rod 9 in the electrode rod clamp 13 to ensure that the electrode rod 9 can be properly connected to the gas-inflated welding component 7 through the feed groove 22. Connect the high-pressure inflation and welding mechanism to an external power supply through appropriate wiring to ensure normal power supply to the equipment. Check whether the control wiring in the control box 14 is correctly connected and whether the functions of each control button and switch are normal. Place the product to be processed on the quick-change V-block 4 at the top center of the feeding platform 2. The quick-change V-block 4 can quickly adapt and position according to the shape of the product, which is convenient for products of different specifications. After the product is placed, the product position monitoring 5 on both sides of the quick-change V-block 4 on the feeding platform 2 starts working to detect whether the product is placed in the correct position. At the same time, the product presence detection 6 determines whether a product is placed on the quick-change V-block 4. If the product position is incorrect or no product is placed, the system will issue a corresponding prompt, and the operator needs to adjust or replace the product. When the product position monitoring 5 and the product presence detection 6 confirm that the product is placed correctly, the positioning cylinder 10 on the top of the positioning mechanism 3 is activated, pushing the steel ball blocking mechanism 8 on the front side of the positioning mechanism 3 to move. The steel ball blocking mechanism 8 is connected to the inflatable welding part 7, and through its specific structure and action, it positions the product to ensure that the product will not shift during inflation and welding. The clamping cylinder 19 on the rear side of the stop mechanism 8 actuates to further clamp and fix the product, improving its stability during processing. Simultaneously, the buffer sleeve 16 and positioning pins 15 work together to buffer and precisely guide the positioning and clamping process, preventing damage from excessive impact. After positioning and fixing, the gas-inflated welding component 7 undergoes high-pressure inflation through the high-pressure gas inlet / outlet 23 on its side. High-pressure gas enters the interior of the gas-inflated welding component 7, creating specific environmental conditions for subsequent welding processes. During or after inflation, the electrode rod 9 in the electrode rod clamp 13 begins operation. The electrode rod 9 connects to the gas-inflated welding component 7 through the feed groove 22. Under appropriate welding parameters such as current, voltage, and welding time, the welding process is completed.Welding is a process where the heat generated melts and bonds the parts of the product to the surface, completing the welding process.

The inflation welding part 7 on the top of the mounting block 21, together with the high-pressure sealing part 11 on the top and the high-pressure air inlet and outlet port 23 on the side, provides a high-pressure inflation environment for the product, meets specific processing requirements, and improves the function of the equipment.

The clamping cylinder 19 located behind the steel ball blocking mechanism 8 further clamps and fixes the product after positioning. This combination of positioning and clamping ensures that the product will not shift due to external forces during processing, providing stable operation for high-pressure gas inflation and welding. The buffer sleeve 16 at the top of the steel ball blocking mechanism 8 and the internal positioning pin 15 play a buffering role during positioning and clamping, which can effectively avoid hard impact on the product during positioning and clamping, and prevent the product from being damaged or deformed due to impact. It is especially suitable for processing impact-sensitive products. The limit pin 20 set on the right side of the positioning cylinder 10 can limit and adjust the stroke of the positioning cylinder 10.
