Description

Technical Field

[0001] This utility model belongs to the field of welding equipment technology, and specifically relates to a laser welding fixture. Background Technology

[0002] Laser welding is one of the important applications of laser material processing technology. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process is heat conduction type, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses into the interior through heat conduction. By controlling parameters such as the width, energy, peak power and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool. Due to its unique advantages, it has been successfully applied to the precision welding of micro and small parts.

[0003] Chinese patent application number 202323588829.1 discloses a laser welding fixture. By setting a limiting groove, a second telescopic rod, a buckle, and a pressure rod, when the first telescopic rod moves the mounting frame towards the placement plate, the buckle engages in the groove, the pressure rod presses down on the part, and the second telescopic rod extends out and engages in the limiting groove to fix the placement plate, preventing it from shaking and improving its stability. It also prevents the part from shifting during laser welding. A pressing plate can press and fix the placement plate. The moving groove on the pressing plate moves relative to the bolts towards the placement plate, keeping the pressing plate close to it. The bolts fix the pressing plate, allowing the placement plate to move back and forth within the channel formed by the pressing plate and the side of the placement table, facilitating part replacement.

[0004] However, the device requires the workpiece to be welded to be placed in the placement slot for welding, resulting in the welding area being only the surface. When welding is required around the circumference of the workpiece, the orientation of the workpiece needs to be changed midway, which not only interrupts the welding progress but also easily causes burns to the user due to the high temperature generated during welding, posing a certain danger.

[0030] Working principle: All electrical components mentioned in this application are externally connected to a power supply and control switch during use. After installation, first check the installation, fixation, and safety precautions of this utility model before use. During use, the user places the collection box in front of the base plate 1, then places the part to be welded on the carrier plate 18, and then adjusts the positions of sliding seat 3 and sliding seat 4 on the slide rail 2. During adjustment, pull the lifting button 14 upwards to move the sliding rod 17 out of the slot 16. When the sliding rod 17 fully extends out of the slot 16, insert... Rod 15 disengages from slot 13, and then the lifting knob 14 is rotated to displace slide rod 17 from slot 16, thus fixing the position of insert rod 15. The user can then move sliding blocks 3 and 4. After adjusting their positions, the user rotates the lifting knob 14 to align slide rod 17 with slot 16. As slide rod 17 inserts into slot 16, insert rod 15 moves downwards simultaneously. Then, slightly move sliding blocks 3 and 4 to align insert rod 15 with the nearest slot 13. Complete the fixation; align one side of the workpiece to be welded with clamping plate 8, then activate electric push rod 9, causing output shaft 10 to move, which in turn causes clamping plate 11 to firmly hold the workpiece; then electric push rod 122 causes output shaft 123 to retract, causing carrier plate 18 to descend and detach from the workpiece; use welding equipment to weld the workpiece, activating motor 6 during welding, causing motor 6 to rotate shaft 7 and clamping plate 8, which in turn causes the workpiece to rotate, thus allowing the workpiece to be welded to move. The welding operation is carried out. After the welding is completed, the electric push rod 122 drives the carrier plate 18 to rise, and the electric push rod 9 drives the output shaft 10 to retract, so that the welded parts fall on the carrier plate 18. The electric push rod 122 drives the output shaft 123 to move downward. During the process of the output shaft 123 driving the carrier plate 18 to descend, the gear 127 meshes with the rack 128 and rotates, driving the connecting shaft 125 to rotate. The connecting shaft 125 drives the sleeve block 126 and the carrier plate 18 to rotate. The carrier plate 18 pours the welded parts at the top into the collection box for collection.
