Description

Technical Field

[0001] The invention relates to the technical field of laser welding, in particular to a laser welding device used for processing lawn mower parts. Background Art

[0002] A lawn mower is a mechanical tool used to trim and clean vegetation. Its main function is to cut grass or other low plants to the required height through a specific cutting device to maintain the flatness, beauty and healthy growth of vegetation, or to clean weeds in wasteland, roadsides and other areas. Laser welding is a welding method that uses a high-energy-density laser beam as a heat source. After focusing, the laser beam can produce extremely high energy density in a very small area. When the laser beam irradiates the surface of the workpiece, the light energy is absorbed by the workpiece and quickly converted into heat energy, causing the workpiece material to melt or even vaporize instantly to form a molten pool. Subsequently, under the continuous action of the laser beam, the liquid metal fuses together. When the laser beam is removed, the molten pool cools and solidifies, thereby achieving material connection.

The invention drives the conduction rod and the sliding plate to move on the slide groove by a driving motor, thereby driving the piston rod and the piston block to move inside the spray barrel, and the coolant will be extracted through the rear end connecting pipe of the spray barrel, and then discharged from the top connecting pipe again. After being splashed to the atomizing block, it forms an atomized and scattered state, increasing the contact with the air, achieving the effect of cooling the coolant and accelerating the speed.

[0032] The following will be combined with the attached Figures 1 to 8 The technical solution of the present invention is described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] In this embodiment: the laser welding device for processing lawn mower parts is mainly divided into three parts: operating table 1, clamping mechanism 2 and welding mechanism 3. When the device is in use, first put the parts to be welded on both sides into the rotating ring 217, and then start the clamping motor 224 to drive the inner ring frame 2171 and the outer ring frame 2172 to rotate counterclockwise. At this time, the multiple groups of swing arms 219 swing inward relative to the clamping cavity 206 to clamp and fix the parts. When the incisions of the parts on both sides are perpendicular to the parts, the moving clamping part 202 is coaxial with the fixed clamping part 201, and the incisions of the parts on both sides are in contact. At this time, the turning cylinders 209 on both sides are driven and cooperate with the laser welding gun 305 on the top to perform all-round welding on the incision. When the incision of the part is tilted, the moving clamping part 202 is driven to deflect by the swing motor 102. At this time, the welding mechanism 3 also deflects synchronously with the moving clamping part 202. When the incisions of the parts on both sides abut, the flip cylinder 209 remains fixed and drives the laser welding gun 305 to reciprocate along the circular rail 301 and perform 360-degree welding on the incision.

[0035] See attached Figure 1 and attached Figure 3 A fixed seat 204 is arranged in the middle of the support frame 228 located on the fixed clamping part 201, a swing seat 205 movably connected to the fixed seat 204 is arranged in the middle of the support frame 228 located on the movable clamping part 202, and the ring rail 301 is fixedly arranged on the top of the swing seat 205.

[0036] In this embodiment: In order to increase the degree of freedom and thus meet the welding operations of parts with cuts of different specifications, the movable clamping part 202 is allowed to deflect freely relative to the operating table 1, and the ring rail 301 is fixedly set on the top of the swing seat 205, thereby ensuring that the welding mechanism 3 deflects synchronously with the movable clamping part 202.

[0037] See attached Figure 1 -Attached Figure 3 A through annular groove 101 is provided in the middle of the operating platform 1, and a swinging gear ring 203 located in the annular groove 101 is fixedly provided at the bottom of the support frame 228 located on the moving clamping part 202. A swinging motor 102 is installed at the bottom of the operating platform 1, and a driving gear 103 meshing with the swinging gear ring 203 is installed at the output end of the swinging motor 102.

[0038] In this embodiment, in order to drive the moving clamping part 202 to automatically deflect, a swing gear ring 203 and a swing motor 102 structure that cooperate with each other are designed.

[0039] See attached Figure 1 and attached Figure 8 A driven roller 213 located on both sides of the flip cylinder 209 is movably installed between the moving cavity 207, and a positioning roller 214 close to the flip cylinder 209 is movably installed between the driven rollers 213. A flip motor 215 is installed on the inner wall of the support frame 228. An active roller 212 located in the moving cavity 207 is installed at the output end of the flip motor 215. A belt 216 for driving the flip cylinder 209 to rotate is connected between the active roller 212, the driven roller 213 and the positioning roller 214.

[0040] In this embodiment: driven by the flip motor 215, the active roller 212 and the driven roller 213 rotate in conjunction. Since the outer wall of the belt 216 abuts against the flip cylinder 209 and the angle between the belts 216 is greater than the second flip notch 211, the flip cylinder 209 drives the outer rotating ring 217 to rotate freely.

[0041] See attached Figure 4 and attached Figure 7 -Attached Figure 8 A first flip notch 208 communicating with the clamping cavity 206 is provided on the top of the support frame 228, a second flip notch 211 cooperating with the first flip notch 208 is provided on the outer wall of the flip cylinder 209, and clamping notches 218 for conveniently clamping the parts to be welded are provided on the inner ring frame 2171 and the outer ring frame 2172.

[0042] In this embodiment, in order to facilitate the clamping of parts, it is not necessary to penetrate into the clamping cavity 206 from the side as in the prior art, so a first flip notch 208 and a second flip notch 211 structure that cooperate with each other are provided. In order to ensure that the parts are smoothly inserted, the clamping notch 218 is flush with the second flip notch 211 in the initial unclamped state.

[0043] See attached Figure 8 , limiting rollers 229 located on both sides of the first flip notch 208 are movably installed between the movement chambers 207.

[0044] In this embodiment, when the turning cylinder 209 rotates, since the angle between the driven rollers 213 on both sides is less than 180 degrees, a symmetrical limiting roller 229 structure is designed to ensure smooth rotation of the turning cylinder 209 and avoid accidental falling off.

[0045] See attached Figure 4 -Attached Figure 5 The outer side of the swing arm 219 is movably arranged on the outer wall of the limiting ring platform 210, and a clamping wheel 220 is movably installed at the end of the swing arm 219. A plurality of swing frames 221 are movably installed between the inner ring frame 2171 and the outer ring frame 2172, and the swing arm 219 is movably arranged in the swing frame 221; a boss 222 is also arranged on the outer wall of the inner ring frame 2171, and a swing block 223 is movably installed on the boss 222. A clamping motor 224 is installed on the limiting ring platform 210, and a threaded rod 225 is installed at the output end of the clamping motor 224, and the threaded rod 225 is threadedly connected to the swing block 223.

[0046] In this embodiment: when the clamping motor 224 drives the inner ring frame 2171 and the outer ring frame 2172 to rotate counterclockwise, the multiple sets of swing arms 219 swing inward relative to the clamping cavity 206 to clamp and fix the parts, and the inner ring frame 2171 and the outer ring frame 2172 block the first flip notch 208 and the second flip notch 211. When the clamping motor 224 drives the inner ring frame 2171 and the outer ring frame 2172 to rotate clockwise, the multiple sets of swing arms 219 swing outward relative to the clamping cavity 206 to unlock the parts, and the clamping notches 218 on the inner ring frame 2171 and the outer ring frame 2172 are flush with the first flip notch 208 and the second flip notch 211.

[0047] See attached Figure 5 -Attached Figure 6 A ring-shaped limiting rail 226 is arranged on the inner wall of the inner ring frame 2171 , and a limiting groove 227 cooperating with the limiting rail 226 is opened on the outer wall of the limiting ring platform 210 .

[0048] In this embodiment, in order to make the rotating ring 217 rotate freely relative to the limiting ring platform 210 and ensure its stability during rotation, a limiting rail 226 and a limiting groove 227 structure that cooperate with each other are designed.

[0049] See attached Figure 1 -Attached Figure 3 A traveling gear ring 302 is installed on the inner wall of the ring track 301, and a traveling motor 307 is installed on the outer wall of the moving hoop 303; a lifting cylinder 304 is also installed on the inner wall of the moving hoop 303, and the top of the laser welding gun 305 is connected to the output end of the lifting cylinder 304, and a storage box 306 is also fixedly provided below the ring track 301.

[0050] In this embodiment, in order to perform all-round welding on the parts, the laser welding gun 305 is freely rotated along the ring track 301 by the travel motor 307. In order to avoid welding dead angles, a driving device (not shown) is also provided between the laser welding gun 305 and the lifting cylinder 304, so as to ensure that the laser welding gun 305 can swing freely relative to the moving hoop 303 to adjust the deflection angle. In order to collect the welding slag and avoid damage to the equipment, a storage box 306 structure is designed.

[0051] See attached Figure 1 -Attached Figure 2 A control panel 104 is also provided on the outer wall of the operating table 1.

[0052] In this embodiment, in order to control the overall operation of the device, a control panel 104 structure is designed.

[0053] Working principle of the present invention: When the device is used, firstly, the parts to be welded on both sides are placed into the rotating ring 217, and then the clamping motor 224 is started to drive the inner ring frame 2171 and the outer ring frame 2172 to rotate counterclockwise. At this time, the multiple sets of swing arms 219 swing inward relative to the clamping cavity 206 to clamp and fix the parts. When the cutouts of the parts on both sides are perpendicular to the parts, the moving clamping part 202 and the fixed clamping part 201 are coaxial, and the cutouts of the parts on both sides are abutted. At this time, the turning cylinders 209 on both sides are driven and the laser welding gun 305 on the top are used to perform all-round welding on the cutouts. When the cutouts of the parts are tilted with the parts, the moving clamping part 202 is driven to deflect by the swing motor 102, and the welding mechanism 3 is also synchronously deflected with the moving clamping part 202. When the cutouts of the parts on both sides are abutted, the turning cylinder 209 remains fixed and drives the laser welding gun 305 to reciprocate along the ring rail 301 and perform 360-degree welding on the cutouts.
