Description

Technical Field

[0001] The utility model relates to the field of welding equipment, in particular to welding equipment for producing metal parts. Background Art

[0002] Laser welding gun is a professional equipment that uses a high energy density laser beam as a heat source for welding operations; it is characterized by high efficiency, precision and high quality, and is widely used in the connection and repair of metal materials.

[0003] The protective lens and focusing lens in the laser welding gun are two very important optical components, which play a key role in ensuring the welding quality and the normal operation of the equipment. When these components are worn, contaminated or damaged, timely replacement is very necessary. In the prior art, when the lens holder is taken out to replace the protective lens and focusing lens, it is necessary to stick masking tape on the mounting port of the laser welding gun lens holder to prevent external dust and impurities from entering the welding gun through the mounting port. However, it is troublesome to stick masking tape, and workers do not carry masking tape with them when performing welding operations. Therefore, many workers do not perform this operation when replacing, resulting in dust entering the welding gun, affecting the subsequent use of the laser welding gun, and greatly reducing the life of the laser welding gun. Utility Model Content

[0004] In order to overcome the disadvantage that the entire lens seat needs to be taken out for replacement when replacing the protective lens and the focusing lens of the existing laser welding gun, which causes dust to easily enter the interior of the laser welding gun through the mounting port of the lens seat, affecting the subsequent use of the laser welding gun and greatly reducing the life of the laser welding gun, the utility model provides a welding device for metal parts production.

[0005] The technical implementation scheme of the utility model is: a welding equipment for metal parts production, including a laser welding gun, a lens seat and a wire feeding tube; two lens seats are fixedly connected to the laser welding gun; the wire feeding tube is rotatably connected to the laser welding gun; it also includes a magnetic block, a mounting seat, a pressure ring and a clamping assembly; a limiting part is arranged on the rear side of each lens seat, the limiting part slides in the laser welding gun and will not slide out of the laser welding gun; a plurality of upper and lower symmetrical magnetic blocks are fixedly connected to the front side of the limiting part; a mounting seat for mounting a lens is fixedly connected in each lens seat; a pressure ring is threadedly connected to the right side of each mounting seat; a clamping assembly for clamping the lens is connected to the pressure ring.

[0006] More preferably, the clamping assembly includes a rotating ring and a rubber pad; each pressure ring is rotatably connected to a rotating ring on the left side; each rotating ring is fixedly connected to a rubber pad on the left side, and the rubber pad is located on the inner ring of the rotating ring.

[0007] More preferably, a friction bump is further included; the friction bump is arranged at the handle of the laser welding gun.

[0008] More preferably, the friction bump is made of silicone.

[0009] More preferably, the right side surface of the pressure ring is a rough surface.

[0010] More preferably, an aligner is further included; the aligner is fixedly connected to the lower side of the wire feeding tube.

[0011] Compared with the prior art, the utility model has the following advantages: the limiting part prevents the worker from pulling the mirror holder completely out of the laser welding gun, and the rear side of the mirror holder seals the installation port of the laser welding gun to prevent dust from entering the laser welding gun;

[0012] When replacing the lens, the worker can judge whether the lens is installed correctly by whether obvious pressure is encountered when tightening the pressure ring, thereby solving the problem that the existing focusing lens is small and the convex surface is not obvious, which makes it easy for workers to install it incorrectly. The rotating ring is rotatably connected to the pressure ring, so when the rubber pad contacts the lens, when the worker continues to tighten the pressure ring, the pressure ring will rotate on the rotating ring. At the same time, as the pressure ring is tightened, the rotating ring and the rubber pad are squeezed toward the lens to compress the lens, thereby preventing the rubber pad from being worn by the pressure ring due to the continued rotation of the rubber pad after the rubber pad contacts the lens.

[0013] The utility model also has the following beneficial effects:

[0014] During the welding process, workers can open the aligner, which will emit an infrared laser line. The infrared laser line is in the same plane as the handle of the laser welding gun and the welding point. Therefore, the infrared laser line emitted by the aligner will point to the weld position, providing a reference for workers when welding. Workers only need to keep the infrared light at the weld to perform welding work more accurately. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] A welding device for producing metal parts, such as Figure 1-Figure 5 As shown, it includes a laser welding gun 1, a lens holder 2 and a wire feeding tube 3; the laser welding gun 1 is bolted with two lens holders 2, wherein the right lens holder 2 is installed with a protective lens 555, and the left lens holder 2 is installed with a focusing lens; the laser welding gun 1 is rotatably connected with the wire feeding tube 3;

[0024] It also includes a magnetic block 101, a mounting seat 102, a pressure ring 103 and a clamping assembly; a limiting portion 2001 is provided on the rear side of each mirror seat 2, and the limiting portion 2001 slides in the laser welding gun 1 and will not slide out of the laser welding gun 1; two upper and lower symmetrical magnetic blocks 101 are fixedly connected to the front side of the limiting portion 2001; each mirror seat 2 is bolted with a mounting seat 102; each mounting seat 102 is threadedly connected to a pressure ring 103 on the right side; and a clamping assembly is connected to the pressure ring 103.

[0025] The clamping assembly includes a rotating ring 104 and a rubber pad 105 ; the left side of each pressing ring 103 is rotatably connected to a rotating ring 104 ; the left side of each rotating ring 104 is fixedly connected to a rubber pad 105 , and the rubber pad 105 is located at the inner ring of the rotating ring 104 .

[0026] It also includes a friction bump 106 ; the friction bump 106 is arranged on the handle of the laser welding gun 1 .

[0027] The friction bump 106 is made of silicone, which is soft, wear-resistant, anti-aging, skin-friendly, has a certain hygroscopicity, and can enhance the sweat absorption effect by adding a microporous structure.

[0028] The right side of the pressing ring 103 is a rough surface, which is convenient for workers to rotate and tighten the pressing ring.

[0029] The working principle of the above embodiment is as follows:

[0030] When workers need to replace the protective lens or focusing lens, such as Figure 2-Figure 5 As shown; first, the worker loosens the connecting screws between the lens holder 2 and the laser welding gun 1, and then pulls the lens holder 2 forward. During this process, the limiting part 2001 slides forward in the laser welding gun 1. When the front side of the limiting part 2001 contacts the laser welding gun 1, the magnetic block 101 is adsorbed on the laser welding gun 1. At this time, the mounting port of the laser welding gun 1 is sealed through the rear side of the lens holder 2 to prevent dust from entering the laser welding gun 1. Then the worker loosens the connecting screws between the mounting seat 102 and the lens holder 2, and then pulls out the mounting seat 102; and unscrews the pressing ring 103, and then takes out the damaged lens 555, and then replaces the new lens 555;

[0031] When installing the new lens 555, the focusing lens is usually a convex lens. In this case, the convex surface needs to be installed toward the pressing ring 103. The focusing lens is small and the convex surface is not obvious, so workers are prone to installation errors. Therefore, when installing the focusing lens, Figure 4 and Figure 5 As shown in the figure: at this time, if the worker directs the convex surface of the lens 555 toward the pressing ring 103, when the worker screws the pressing ring 103 into the mounting seat 102, the rubber pad 105 located on the inner ring of the rotating ring 104 will first contact the convex part of the pressing ring 103, so the worker will feel obvious pressure when tightening the pressing ring 103. If the convex surface of the lens 555 is not directed toward the pressing ring 103, then when the pressing ring 103 is tightened, the rubber pad 105 will not first contact the pressing ring 103, so the worker will not feel obvious pressure when tightening the pressing ring 103. In addition, through this method, the worker can judge when tightening the pressing ring 103. Check whether the broken lens 555 is installed correctly; and the rotating ring 104 is rotatably connected with the pressing ring 103, so when the rubber pad 105 contacts the lens 555, the worker continues to tighten the pressing ring 103, and the pressing ring 103 rotates on the rotating ring 104. At the same time, as the pressing ring 103 is tightened, the rotating ring 104 and the rubber pad 105 are squeezed toward the lens 555 to compress the lens 555, so as to avoid the rubber pad 105 contacting the lens 555 and causing wear to the lens 555 due to the pressing ring 103 continuing to drive the rubber pad 105 to rotate, and the right side of the pressing ring 103 is a rough surface, which is convenient for the worker to rotate and tighten the pressing ring;

[0032] Furthermore, during the welding process, the friction of the worker holding the laser welding gun 1 is improved by the friction bump 106, which greatly improves the comfort of the worker holding the laser welding gun 1. The friction bump 106 is made of silicone, which is soft, wear-resistant, anti-aging, skin-friendly, has certain hygroscopicity, and can enhance the sweat absorption effect by adding a microporous structure.

[0033] Example 2

[0034] On the basis of Example 1, Figure 1As shown, an aligner 107 is also included; the aligner 107 is fixedly connected to the lower side of the wire feeding tube 3.

[0035] The working principle of the above embodiment is as follows:

[0036] During the welding process, the worker can open the aligner 107, and the aligner 107 will emit an infrared laser line, and the infrared laser line is in the same plane as the handle and welding point of the laser welding gun 1. Therefore, the infrared laser line emitted by the aligner 107 will point to the weld position, thereby providing a reference for the worker when welding. The worker only needs to keep the infrared light at the weld to perform the welding work more accurately.
