Description

Technical Field

[0001] The invention relates to the technical field of laser welding, and mainly relates to a laser welding machine used for welding irregular metal parts. Background Art

[0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding is one of the important aspects of the application 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 a heat conduction type, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the inside through heat conduction. By controlling the width, energy, peak power and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool;

[0003] At present, when laser welding irregular metal parts, due to their irregular size, many laser welders are difficult to perform laser welding. Therefore, laser welding of irregular metal parts is still more often done by manually holding the irregular metal parts. However, this has the disadvantage that it is very easy to cause harm to workers, and the quality of laser welding is also low, that is, the quality of the weld at the welding point is low. Therefore, it is necessary to design a laser welding machine for welding irregular metal parts to solve the above problems. Summary of the invention

[0004] The object of the present invention is to provide a laser welding machine for welding irregular metal parts to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a laser welding machine for welding irregular metal parts, comprising a bracket, the top of the bracket is connected to a stabilizing device, the bottom of the bracket and the stabilizing device is connected to a clamping device, one side of the clamping device is connected to a limiting device, and one side of the limiting device is connected to the irregular metal part;

[0006] The top of the bracket is connected to a driving device, and the top of the bracket is connected to a welding device. The welding device includes a turntable rotatably connected to the top of the bracket, a first cylinder connected to one side of the bottom of the turntable, a Z-shaped plate connected to the driving end of the first cylinder and a second cylinder connected to one side of the bottom of the Z-shaped plate, the driving end of the second cylinder is connected to a fixed plate, one side of the fixed plate is connected to a buffer component, one side of the buffer component is connected to a protective shell, one side of the buffer component is connected to a welding device, and the welding device is located inside the protective shell.

[0007] In the present invention, the first cylinder facilitates the lowering of the Z-shaped plate so that the two irregular metal parts are in contact and the welding equipment is lowered. The second cylinder facilitates the movement of the protective shell so that the protective shell is close to the irregular metal part. The buffer assembly provides a buffer space for the protective shell. The turntable rotates to rotate the welding equipment and the protective shell, so that the elastic force of the buffer assembly causes the protective shell to slide along the surface of the irregular metal part.

[0008] Furthermore, the driving device includes a rotating motor connected to one side of the top of the bracket, a first gear connected to the driving end of the rotating motor, a second gear meshingly connected to one side of the first gear and a hollow cylinder connected to the bottom of the second gear, and the bottom of the hollow cylinder is connected to a turntable.

[0009] In the present invention, the first gear drives the second gear to rotate, thereby driving the hollow cylinder to rotate, and further causing the turntable to rotate.

[0010] Furthermore, the buffer assembly includes a first telescopic member connected to both sides of the fixed plate, a first spring sleeved on the first telescopic member and a buffer plate connected to one side of the first telescopic member, and one side of the buffer plate is connected to the welding equipment and the protective shell.

[0011] In the present invention, the first spring facilitates the reset of the buffer plate, thereby making the protective shell close to the irregular metal piece.

[0012] Furthermore, a C-shaped frame is fixed on the top of the bracket, and the bottom of the C-shaped frame is connected to a stabilizing device. The stabilizing device includes a sliding rod connected to the bottom of the C-shaped frame and a sleeve slidably connected to the bottom of the sliding rod. The bottom of the sleeve is connected to a clamping device, and the bottom of the sleeve is rotatably connected to a Z-shaped plate.

[0013] In the present invention, the cooperation between the slide bar and the sleeve facilitates improving the stability of the clamping device and facilitates the clamping device to be lifted and lowered along with the Z-shaped plate.

[0014] Furthermore, the clamping device includes a fixing seat connected to the bracket and the bottom of the sleeve, a driving motor connected to one side of the fixing seat, a bidirectional screw connected to the driving end of the driving motor, and a clamping plate connected to both sides of the bidirectional screw.

[0015] In the present invention, the rotation of the bidirectional screw rod facilitates the clamping plates on both sides to move in opposite directions, thereby achieving the clamping and loosening of the irregular metal piece.

[0016] Furthermore, the limiting device includes a C-shaped plate connected to one side of the fixing seat, a second telescopic member connected to both sides of the C-shaped plate, a second spring sleeved on the second telescopic member and a limiting plate connected to one side of the second telescopic member.

[0018] Furthermore, a first bevel is provided on the inner side of the top of the limiting plate, and the limiting plate cooperates with the irregular metal part.

[0019] In the present invention, the first beveled edge facilitates the irregular metal piece to press the limiting plate, thereby causing the limiting plate to shrink.

[0020] Furthermore, a rubber pad is installed on the inner side of the clamping plate.

[0021] In the present invention, the rubber pad increases the friction between the clamping plate and the irregular metal piece, thereby preventing the irregular metal piece from sliding.

[0022] Furthermore, the two sides of the protective shell are rotatably connected to the rollers, and the two sides of the protective shell are provided with second bevels, and the second bevels are located on the two sides of the rollers.

[0023] In the present invention, the roller reduces the friction between the protective shell and the irregular metal part, avoids scratches on the surface of the irregular metal part, and avoids wear of the protective shell.

[0024] Furthermore, a welding pipe is provided on one side of the welding device, and the welding pipe is located inside the protective shell.

[0025] In the present invention, the welding pipe is located inside the protective shell to protect the welding pipe and prevent the welding pipe from being worn.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] The present invention uses the elastic force of the second spring to make the limit plate squeeze the irregular metal part, thereby limiting the position of the irregular metal part, and drives the bidirectional screw rod to rotate by the driving motor, so that the clamping plates on both sides move in opposite directions, thereby realizing the clamping of the irregular metal part, and the Z-type plate is lowered by the first cylinder, so that the two irregular metal parts are in contact, and the buffer assembly and the protective shell are moved by the second cylinder, so that the protective shell is tightly attached to the irregular metal part. At this time, the first spring is compressed, and the elastic force of the first spring is used to make the protective shell tightly attached to the irregular metal part. The first gear is driven to rotate by the rotating motor, thereby driving the second gear to rotate, and then driving the hollow cylinder and the turntable to rotate, so that the welding equipment and the protective shell are rotated, and the protective shell slides along the surface of the irregular metal part, so that the welding equipment can fully weld the irregular metal part. The device avoids harm to workers and improves the quality of welding. BRIEF DESCRIPTION OF THE DRAWINGS
