[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Example: An automatic welding equipment for mechanical parts, please see below. Figures 1 to 7As shown, the equipment includes a base plate 1, a gantry frame 2, a mounting frame 3, a cylinder 4, a welded component 5, a welding torch 6, a support plate 7, an electric push rod 8, a connecting plate 9, a clamping plate 10, a protective pad 101, an electric push rod 2 11, a push plate 12, a gantry frame 2 13, a laser rangefinder 14, an adjustment frame 15, an adjustment port 151, a rangefinder head 16, a placement frame 17, a fixing plate 18, and a welding torch 2 19. The base plate 1 serves as the supporting foundation for the entire equipment, used to fix and connect all other components. The gantry frame 2 is horizontally connected to the top of the base plate 1. A cylinder 4 is installed at the center of the top of the gantry frame 2. The piston rod of the cylinder 4 is connected to the mounting frame 3. The welded component 5 is installed inside the mounting frame 3. By extending and retracting the piston rod of the cylinder 4, the mounting frame 3 and the welded component 5 are moved. The vertical movement of the welding torch allows for vertical displacement during the welding process. A welding torch 6 is mounted on the right side of the welding component 5, used for welding the mechanical tube. Support plates 7 are symmetrically connected to the top of the base plate 1, supporting the mechanical tube. Electric push rods 8 are symmetrically mounted on the top of the base plate 1, each connected to a connecting plate 9. Clamping plates 10 are symmetrically connected to the sides of the two connecting plates 9 that are close to each other. The extension and retraction of the push rods by the electric push rods 8 causes the connecting plates 9 and clamping plates 10 to clamp and release the mechanical tube. Protective pads 101 are placed on each clamping plate 10 to prevent damage to the surface of the mechanical tube during clamping. Electric push rods 11 are symmetrically mounted vertically upwards on the top right side of the base plate 1. The push rods of the electric push rods 2 11 are all connected to push plates 12. The extension and retraction of the push rods of the electric push rods 2 11 drives the push plates 12 to push or position the mechanical tubes. The two electric push rods 2 11 are located to the left of the connecting plate 9 on the right side. A gantry frame 2 13 is horizontally connected to the front of the top of the base plate 1. The gantry frame 2 13 is located in front of the support plate 7 on the front side. Laser rangefinders 14 are symmetrically installed at the top of the gantry frame 2 13 to measure the distance between mechanical tubes or equipment, providing accurate measurement data. Square openings are symmetrically opened at the center of the top of the gantry frame 2 13. Adjustment frames 15 are slidably installed in each square opening. Adjustment ports 151 are opened at the top of the gantry frame 2 13, and these ports are adapted to the fixing ports on the side of the adjustment frames 15. After moving the adjustment frame 15 to a different position, the locking rod on the adjustment frame 15 is inserted into the adjustment port 151 to fix the adjustment frame 15. The position of the adjustment frame 15 can be moved and adjusted to meet different measurement needs. A distance measuring head 16 is embedded in the middle of the adjustment frame 15. The distance measuring head 16 is connected to the port of the nearby laser rangefinder 14 through a connecting line. The distance measuring head 16 is used to measure the actual distance. A placement frame 17 is connected at the top center of the base plate 1. The placement frame 17 is located between the two support plates 7. A fixing plate 18 is connected to the left side of the placement frame 17. A welding gun 2 19 is installed on the upper part of the fixing plate 18. The welding gun 2 19 is connected to the left port of the welding part 5 through a connecting line. The welding gun 2 19 is used to perform additional welding operations on the workpiece.

[0024] When using an automated welding equipment for mechanical parts, first, place the mechanical tube to be welded on the support plate 7, ensuring the tube is stable and correctly positioned. Next, adjust the position of the adjusting frame 15 on the gantry frame 13 according to the tube's size and welding requirements. Adjusting the position of the adjusting frame 15 allows it to better accommodate mechanical tubes of different sizes, ensuring measurement accuracy. After adjustment, insert the locking lever on the adjusting frame 15 into the adjusting port 151 to fix its position. This step is crucial for ensuring that the distance measuring head 16 can stably and accurately measure the distance between mechanical tubes or equipment.

[0025] Next, check the connection cable between the distance measuring head 16 and the laser rangefinder 14 to ensure they are correctly connected. Also, ensure that the distance measuring head 16 can accurately measure the distance between the mechanical tubes or equipment. This is crucial for real-time monitoring and adjustment of the welding position during the welding process.

[0026] Next, activate the electric push rod 8 to extend its push rod, causing the connecting plate 9 and clamping plate 10 to move closer to the mechanical tube. When the clamping plate 10 contacts the mechanical tube, continue to apply appropriate pressure to ensure that the mechanical tube is firmly clamped. At the same time, the protective pad 101 prevents damage to the surface of the mechanical tube during clamping.

[0027] According to the welding requirements, the electric push rod 11 is activated, causing its push rod to extend or retract, which in turn drives the push plate 12 to push the mechanical tube. Due to the friction between the push plate 12 and the mechanical tube, the mechanical tube can be precisely positioned or its welding position can be adjusted. This step is crucial to ensuring the accurate positioning of the mechanical tube during the welding process.

[0028] Then, cylinder 4 is activated, extending its piston rod and moving the mounting frame 3 and welding component 5 downwards above the mechanical tube. At this point, welding torch 6 begins operation, performing welding on the mechanical tube. The welding parameters of welding torch 6 can be adjusted according to the welding process requirements to ensure welding quality and efficiency.

[0029] For additional welding operations, welding torch 219 can be activated and connected to the left port of workpiece 5 via a connecting cable to perform welding. This allows for further fulfillment of complex welding requirements.

[0030] During the welding process, it is necessary to continuously monitor the measurement data provided by the laser rangefinder 14 to ensure that the distance between the mechanical tubes or equipment remains within the predetermined range. Depending on actual needs, the positions and parameters of the electric push rod 1 8, electric push rod 2 11, and cylinder 4 can also be adjusted to ensure welding quality and efficiency.

[0031] After welding is completed, turn off welding torch 6 and welding torch 19. Then activate electric push rod 8 to retract its push rod, release clamp 10, and release the mechanical tube. Finally, remove the welded mechanical tube from support plate 7 for further processing or inspection.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of claim 1.
