With the increasing demand for pressure gauges across various industries, their production efficiency and quality are receiving increasing attention.

[0003] Welding is a crucial step in the production of pressure gauges. However, traditional pressure gauge welding relies primarily on manual operation. Manual welding has several significant drawbacks: firstly, it demands extremely high skill levels from workers, and the varying proficiency and technical abilities among different workers lead to inconsistent weld quality, making it difficult to guarantee product consistency and stability, thus affecting the overall performance and lifespan of the pressure gauge; secondly, manual welding is inefficient, unable to meet the demands of large-scale production, and the prolonged repetitive manual labor easily causes worker fatigue, further reducing weld quality and increasing the defect rate. Therefore, those skilled in the art have provided an automated welding device for pressure gauge production to address the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this invention is to provide an automated welding equipment for pressure gauge production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automated welding equipment for pressure gauge production includes a main body, a main turntable, a support frame, and an upper clamping seat.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. Multiple Fixing Guarantees: Initial fixation is achieved by inserting the lower end of the pressure gauge into the insert. Then, with the clamping of the lower and upper clamps, the upper clamp moves up and down by rotating the threaded column, which can firmly fix the pressure gauge to the part to be welded. This multiple fixing method can effectively prevent the parts from loosening or shifting during the welding process, ensuring welding accuracy and quality.

[0013] 2. Precise welding trajectory: The robotic arm moves the welding torch to the welding position, which can accurately locate the welding point. At the same time, the servo motor drives the component to rotate, so that the welding torch can circle the part to be welded, ensuring the uniformity and integrity of the welding and effectively avoiding welding defects.

[0014] 3. Automated continuous operation: While welding is being performed on one support frame, the other support frame can be simultaneously used for component installation. After welding is completed, the main turntable is rotated by a servo motor to interchange the positions of the two support frames. This allows the equipment to perform installation, welding, and disassembly operations without interruption, greatly improving production efficiency and meeting the needs of large-scale production.

[0021] Please see Figures 1-4 In this embodiment of the present invention, an automated welding equipment for pressure gauge production includes a main body 1, a main turntable 7, a support frame 9, and an upper clamping seat 13. The main turntable 7 is rotatably connected to the upper end of the main body 1. Two support frames 9 are fixedly connected to the upper end of the main turntable 7. A servo motor 10 is fixedly connected to one side of the upper end of each support frame 9. An upper turntable 12 is rotatably connected to the upper end of each support frame 9. Threaded posts 17 are threadedly connected to the upper turntable 12. An upper clamping seat 13 is rotatably connected to the lower end of each threaded post 17.

A through-hole is opened at the bottom of the lower clamping seat 16. Two connecting rods are fixedly connected to the lower end of the lower clamping seat 16. The lower end of the connecting plate is fixedly connected to the lower turntable 14. The servo motors... The power output end of device 10 is fixedly connected to a rotating shaft 11, on which two main sprockets are fixedly connected. Spur sprockets are fixedly connected to the outer sides of the upper turntable 12 and the lower turntable 14. A chain is provided between the main sprockets and the spur sprockets, and the chain meshes with the main sprockets and the spur sprockets. A rotating handle is fixedly connected to the upper end of the threaded column 17. Two limit rods are fixedly connected to the upper end of the upper cassette 13, and the limit rods are slidably connected to the upper turntable 12. A slave gear 8 is fixedly connected to the lower end of the main turntable 7. A servo motor 5 is fixedly installed inside the main body 1. A main gear 6 is fixedly connected to the shaft of the servo motor 5, and the main gear 6 meshes with the slave gear 8.

A robotic arm 3 is fixedly installed on the upper end of the fixed column 2. A welding torch 4 is fixedly installed on one end of the robotic arm. A controller is external to the main body 1.

[0022] The working principle of this utility model is as follows: In use, firstly, the lower end of the pressure gauge (the part to be welded) is inserted into the insert 15 through the through-hole at the bottom of the lower retainer 16 to achieve initial fixation. Next, the pressure gauge is inserted into the lower retainer 16, connecting it to the part to be welded. Then, the handle at the upper end of the threaded column 17 is manually rotated, causing the threaded column 17 to rotate. The threaded column 17 moves the upper retainer 13 downwards, inserting the upper end of the pressure gauge into the upper retainer 13. The upper retainer 13 cooperates with the insert 15, firmly clamping and fixing the pressure gauge and the part to be welded in the middle. Then, the controller controls the robotic arm 3, which moves the welding torch 4 to the welding position. Simultaneously, the servo motor 10 is started, and its power output drives the rotating shaft 11 to rotate. The main sprocket on the rotating shaft 11 rotates accordingly. The chain drives the outer sprockets of the upper turntable 12 and the lower turntable 14 to rotate, which in turn causes the pressure gauge and the workpiece to be welded to rotate. The welding torch 4 welds the pressure gauge and the workpiece to be welded at the welding point. During its rotation, the welding torch 4 completes the welding by circling around the workpiece. While welding, the pressure gauge and the workpiece to be welded can be installed on another support frame 9. After welding is completed, the servo motor 5 is started, and the main gear 6 on its shaft rotates, which drives the driven gear 8 meshing with the main gear 6 to rotate. The driven gear 8 drives the main turntable 7 to rotate, and the main turntable 7 drives the left and right support frames 9 to exchange positions. At this time, the pressure gauge and the workpiece to be welded can be disassembled and installed at one support frame 9, and the welding operation can be performed at the other support frame 9, thereby improving the working efficiency of the equipment.
