Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a high-efficiency laser welding device for condensers. Background Technology

[0002] As a core component of the refrigeration system, the welding quality of the condenser directly affects the equipment's sealing performance, pressure resistance, and service life. Laser welding technology, with its advantages of small heat-affected zone, fast welding speed, and high precision, has gradually replaced traditional argon arc welding and resistance welding processes, becoming the mainstream welding method in condenser manufacturing.

[0003] However, existing laser welding equipment still faces the following technical bottlenecks in practical applications:

[0004] First, condensers of different specifications vary in size, while traditional welding equipment mostly uses a fixed clamping structure, which can only accommodate condensers of a single size. When the workpiece specifications change, the entire set of clamps needs to be replaced, resulting in long debugging time and high costs. Moreover, the clamping parts are mostly in hard metal contact, which can easily leave indentations or damage on the condenser surface.

[0005] Secondly, laser welding generates metallic fumes and harmful gases, such as zinc oxide and ozone. These harmful substances float in the air and can endanger the health of operators. Utility Model Content

[0006] This utility model relates to a high-efficiency laser welding device for condensers, which solves the problems of traditional welding devices that mostly adopt fixed clamping structures, can only be adapted to condensers of a single size, and generate metal fumes and harmful gases during laser welding, which float in the air and endanger the health of operators.

[0007] This utility model provides a high-efficiency laser welding device for condensers, specifically including: an operating table;

[0008] The main body of the operating table is a rectangular plate structure. Four support legs are fixedly installed on the lower end face of the operating table, and a fixed vertical plate is welded to the left side of the upper end face of the operating table.

[0009] A drive motor is fixedly mounted on the outer end face of the fixed vertical plate, and a drive shaft is connected to the front end face of the drive motor.

[0010] A sliding vertical plate is located on the upper end face of the operating table. A connecting plate is fixedly installed below the outer end face of the sliding vertical plate, and two connecting holes are opened on the surface of the connecting plate.

[0011] The limiting plate is provided in two symmetrical sets. The left limiting plate is fixedly connected to the drive shaft at the front end of the drive motor, and the right limiting plate has a rotating shaft installed on its outer end face. The rotating shaft is rotatably connected to the surface of the sliding vertical plate.

[0012] The hanging plate is fixedly installed on the upper end face of the fixed vertical plate. The horizontal plate of the hanging plate has a track groove, and a laser welding gun is slidably locked inside the track groove.

[0013] Furthermore, the upper surface of the operating table has two transverse sliding grooves, and fastening blocks are slidably installed inside the transverse sliding grooves. Fastening screws are fixedly installed on the upper surface of the fastening blocks.

[0014] Furthermore, the surface of the connecting plate has two connecting holes, and the fastening screw at the upper end of the fastening block is engaged inside the connecting holes, with a nut connected to the surface of the fastening screw.

[0015] Furthermore, rubber strips are evenly installed on the inner end face of the vertical plate of the limiting plate, and the outer end face of the rubber strips has an arc-shaped structure.

[0016] Furthermore, the surface of the sliding vertical plate has two first through holes. When the right end limiting plate is in a horizontal state, the fixing pin passes through the first through hole and is engaged in the second through hole on the surface of the limiting plate.

[0017] Furthermore, a connecting block is fixedly installed on the outer end face of the laser welding gun, and a smoke extraction tube is fixedly installed on the outer end face of the connecting block.

[0018] This invention provides a high-efficiency laser welding device for condensers, which has the following advantages:

[0019] In this invention, the condenser workpiece is placed between two sets of symmetrical limiting plates. The left limiting plate is fixedly connected to the drive shaft of the drive motor, and the right limiting plate is rotatably connected to the sliding vertical plate through a rotating shaft, so that the drive motor can drive the two limiting plates to rotate. The arc-shaped rubber strip on the inner end face of the limiting plate fits against the surface of the condenser, which ensures clamping stability and avoids damage to the workpiece.

[0020] Furthermore, by mounting the fastening block in the transverse groove, the worker can move the position of the sliding vertical plate left and right according to the length of the condenser workpiece, thereby adjusting the distance between the two limiting plates to accommodate condensers of different sizes. The outer end face of the right limiting plate has two second through holes. When fixing the condenser workpiece, a fixing pin can be passed through the first through hole on the surface of the sliding vertical plate and then inserted into the second through hole to fix the right limiting plate.

[0021] In addition, the drive shaft at the front end of the drive motor can rotate the limit plate half a turn, so that the back of the workpiece faces upward, thus allowing the back to be welded after the front is welded, improving welding efficiency. The upper part of the laser welding gun is slidably mounted in the track groove, allowing the laser welding gun to move back and forth inside the track groove. The design of the track groove ensures that the welding gun moves smoothly. Combined with the rotation of the workpiece, it can complete the automated welding of circular or straight weld seams.

[0022] In addition, a connecting block is fixedly installed on the inner end face of the fumigation tube, and the connecting block is fixedly installed on the outer end face of the laser welding gun. The end of the fumigation tube has an umbrella-shaped structure. The fumigation tube is connected to an external dust collection device, which absorbs the smoke and dust generated during welding, thereby improving the working environment and avoiding pollution.

[0042] The upper surface of the operating table 1 has two horizontal sliding grooves 102. The inside of the horizontal sliding grooves 102 is fitted with fastening blocks 6. The upper surface of the fastening blocks 6 is fixedly installed with fastening screws 601. The surface of the connecting plate 4 has two connecting holes 401. The fastening screws 601 at the upper end of the fastening blocks 6 are engaged in the connecting holes 401. A nut is connected to the surface of the fastening screws 601. In use, by the setting of the fastening blocks 6 sliding in the horizontal sliding grooves 102, the worker can move the position of the sliding vertical plate 3 left and right according to the length of the condenser workpiece, thereby achieving the purpose of adjusting the distance between the two limit plates 5, thus adapting to condensers of different sizes. After the worker tightens the nut on the surface of the fastening screws 601, the sliding vertical plate 3 can be fixed.

[0043] Among them, rubber strips 501 are evenly installed on the inner end face of the vertical plate of the limiting plate 5. The outer end face of the rubber strip 501 is an arc-shaped structure. In use, the arc-shaped rubber strip 501 on the inner end face of the limiting plate 5 fits against the surface of the condenser, which not only ensures clamping stability but also avoids damage to the workpiece.

[0044] The sliding vertical plate 3 has two first through holes 301 on its surface. When the right end limiting plate 5 is in a horizontal state, the fixing pin passes through the first through hole 301 and is engaged in the second through hole 502 on the surface of the limiting plate 5, which can fix the right side limiting plate 5.
