Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and more specifically to an automatic fixture for welding equipment and its clamping method. Background Technology

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure. Modern welding utilizes a variety of energy sources, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasound. Besides its use in factories, welding can be performed in various environments, such as outdoors, underwater, and in space. Welding is a process that joins two or more similar or dissimilar materials together through atomic or molecular bonding and diffusion.

[0003] A search revealed Chinese patent CN217071350U, which discloses a parts fixture for welding equipment, comprising a first placement slot, a second placement slot, a pressure plate, and a threaded shank. In use, the fixture is placed on the working platform of the welding equipment via a base plate. Two machined round rods and two machined rectangular rods are then taken. The round rods are placed into the second placement slots of their respective fixing mechanisms, while the rectangular rods are placed into their corresponding first placement slots. At this point, the ends of the round rods are in contact with the limiting baffles, and the two ends of the rectangular rods are in contact with the round rods. The pressure plate is then moved, pressing against the round rods and displacing the fixing notch to the outside of the threaded rod. The threaded locking block is then turned, pressing against the pressure plate with the help of the threaded rod, thus fixing the round rod to the fixing seat. Finally, the threaded shank is turned, causing its end to abut against the outer wall of the rectangular rod, thus fixing the rectangular tube. Welding can then be performed using the welding equipment.

[0004] However, when using this type of welding equipment with parts fixtures, after the parts are welded, it is necessary to wait for the parts to cool down before the next welding operation can be carried out. Otherwise, the high temperature will damage the fixtures, resulting in low work efficiency. Summary of the Invention

[0014] By adopting the above technical solution, the design enhances the fixing effect on the mounting block and improves the stability of the upper chuck body.

[0027] Step 4: Push the box onto the workbench, then cool the material using the cooling mechanism. Start the motor to rotate the first shaft, which is fixedly connected to the motor output. Since the impeller in the water pump is fixedly connected to the first shaft, the water pump delivers cooling water from the cooling tank to the cooling pipe. Cooling is generated through water cooling. At the same time, the rotation of the first shaft causes the first bevel gear, which is fixedly connected to the first shaft, to rotate. This causes the second bevel gear, which meshes with the first bevel gear, to rotate, driving the fan to rotate. This air cooling accelerates the airflow, allowing the cooling air from the cooling pipe to quickly cool the welded material.

[0028] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0029] 1. This invention provides an automatic fixture for welding equipment and its clamping method. By setting a cooling mechanism, after the part is welded, the box is pushed above the worktable, and then the material is cooled by the cooling mechanism, which effectively reduces the cooling time of the part, facilitates the quick start of the next welding operation, prevents high temperature from damaging the fixture, and improves work efficiency.

[0030] 2. This invention provides an automatic clamp for welding equipment and its clamping method. By setting a positioning mechanism, the workpiece to be welded can be clamped and fixed by the upper chuck body and the worktable, effectively preventing the workpiece from sliding during the welding process, making the welding more precise, improving product quality, effectively improving welding efficiency, avoiding accidental hand injury, and improving work safety.

[0031] 3. The present invention provides an automatic clamp for welding equipment and its clamping method. By setting a fixing mechanism, the upper clamp body can be easily replaced according to different workpieces to be welded, thereby improving the convenience of using the device and facilitating the disassembly and maintenance of the upper clamp body.

[0050] Example 4

[0051] like Figure 1-8 As shown, based on Examples 1-3, the present invention also provides a clamping method for an automatic fixture for welding equipment, comprising the following steps:

[0052] Step 1: Fixing the material. Place the material on the top of the workbench 4 and fix it with the clamping block 803. Specifically, pull the slider 802 so that the clamping block 803, which is fixedly connected to the slider 802, moves away from each other. At this time, the first spring 804 is in a compressed state. After placing the material on the top of the workbench 4, release the slider 802.

[0053] Step 2: Replace the upper chuck body 805 with different materials. First, turn off the power to the electromagnet 907 through the control panel 6 so that the electromagnet 907 no longer attracts the mounting block 902. Then pull the connecting block 904 so that the locking rod 903, which is fixedly connected to the connecting block 904, moves away from each other and away from the mounting block 902. At this time, the disassembly of the upper chuck body 805 is completed.

[0054] Step 3: Drive the upper chuck body 805 to move by the hydraulic cylinder 11 so that the materials to be welded fit together, and then weld the materials by the welding equipment;

[0055] Step 4: Push the box 5 above the workbench 4, and then cool the material through the cooling mechanism 7. Start the motor 7051, so that the first rotating shaft 7052, which is fixedly connected to the output end of the motor 7051, rotates. Since the impeller in the water pump 701 is fixedly connected to the first rotating shaft 7052, the water pump 701 delivers the cooling water in the cooling water tank 702 to the cooling pipe 703. The water cooling generates cold air. At the same time, the rotation of the first rotating shaft 7052 causes the first bevel gear 7053, which is fixedly connected to the first rotating shaft 7052, to rotate. The second bevel gear 7054, which meshes with the first bevel gear 7053, rotates, causing the second bevel gear 7054 to drive the fan to rotate. The air cooling accelerates the air circulation speed, so that the cold air in the cooling pipe 703 quickly cools down the welded material.

[0056] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
