Technical Field

[0001] This utility model relates to the field of welding technology, specifically to laser welding equipment that facilitates the butt welding of steel materials. Background Technology

[0002] Laser welding equipment mainly consists of a laser, a welding head, and a base cabinet. The laser generates a high-energy-density laser beam, which is then output from the welding head. The front of the upper surface of the base cabinet is equipped with a placement platform via an electric cross slide, allowing for flexible adjustment of the platform's position to accommodate different workpiece positioning requirements. The rear of the upper surface of the base cabinet is equipped with a welding head via a cross module, enabling the welding head to be raised, lowered, and moved forward and backward to ensure that the steel joint is fully and effectively covered.

[0003] In the existing laser welding process for steel butt joints, the steel needs to be placed on a platform in advance and positioned and clamped by bolts or clamps at specific locations. However, this process is quite cumbersome when dealing with steel with different splicing shapes, requiring frequent adjustments to the positions of bolts or clamps. This not only reduces production efficiency but also limits the flexible manufacturing capabilities of the equipment, causing inconvenience in actual use.

[0004] Therefore, in order to solve the above problems, laser welding equipment that facilitates the butt welding of steel is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a laser welding device that facilitates the butt welding of steel, with better clamping flexibility and stronger flexible manufacturing capabilities, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a laser welding device for facilitating steel butt welding, comprising an electric cross slide table, a housing fixedly mounted on the upper side of the electric cross slide table, a platform fixedly mounted on the upper side of the housing, a guide groove provided on the platform, and a work box slidably mounted within the guide groove; brake plates are mounted on both sides of the work box via transmission components; a push-pull electromagnet is fixedly mounted on the top inner side of the work box, a crossbeam is fixedly mounted on the lower end of the push-pull electromagnet, and a square slot is provided in the work box for the crossbeam to pass through; both ends of the crossbeam are connected and assembled with the transmission components; a worm gear rotary table is fixedly mounted on the upper side of each work box, and opposing lead screw modules are fixedly mounted on the upper side of each worm gear rotary table; clamping plates are fixedly mounted on the two slides of each opposing lead screw module.

The crossbeam is located between each pair of connecting rods, and the crossbeam has an elongated hole for the pin to pass through.

[0009] Furthermore, each of the pins is rotatably mounted with a roller, which is located inside the elongated hole.

[0010] Specifically, roller belts are fixedly installed on both sides of the work box, and there are two roller belts on each side distributed on the upper and lower parts of the platform.

[0011] Specifically, friction pads are fixedly installed on the upper side of each brake plate, and friction strips aligned with the friction pads are fixedly installed on the bottom of each platform.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 5 This utility model provides a laser welding device for facilitating steel butt welding, including an electric cross slide table 18, which is fixedly installed on a base cabinet. A housing 1 is fixedly installed on the upper side of the electric cross slide table 18, serving as the base for installing and accommodating other components. A platform 6 is fixedly installed on the upper side of the housing 1, which mainly provides support. The platform 6 has a guide groove 16, in which a work box 4 is slidably installed. The electric cross slide table 18 is an existing component used for horizontal and vertical movement adjustment of all structures on the housing 1, and the work box 4 can move along the guide groove 16.

[0027] Brake plates 15 are installed on both sides of the work box 4 via transmission components 5. A push-pull electromagnet 2 is fixedly installed on the top inner side of the work box 4. A crossbeam 3 is fixedly installed at the lower end of the push-pull electromagnet 2. The work box 4 has a square slot for the crossbeam 3 to pass through. Both ends of the crossbeam 3 are connected and assembled with the transmission components 5. The push-pull force on the push-pull electromagnet 2 can be synchronously transmitted to the transmission components 5 on both sides via the crossbeam 3, thereby driving the brake plates 15 to move up and down. When the brake plates 15 are in contact with the lower surface of the platform 6, they act as brakes. When the brake plates 15 are separated from the lower surface of the platform 6, the brakes are released.

[0028] A worm gear rotary table 11 is fixedly installed on the upper side of the work box 4. A counteracting screw module 10 is fixedly installed on the upper side of the worm gear rotary table 11. A clamping plate 7 is fixedly installed on the two slides of each counteracting screw module 10. The counteracting screw module 10 is used to adjust the clamping plate 7 in opposite directions to clamp steel of different widths. The worm gear rotary table 11 is used to rotate the counteracting screw module 10 in the circumferential direction, thereby changing the orientation of the steel. The counteracting screw module 10 and the worm gear rotary table 11 are existing components and can be driven by electric or manual means without affecting the implementation of this embodiment.

[0029] Please see Figure 5 There are four guide grooves 16, which are arranged in a cross shape. The guide grooves 16 arranged in this way make full use of the space and can also meet the usage requirements.

[0030] Please see Figure 3 The transmission assembly 5 includes a wing plate 53 and connecting rods 51. Wing plates 53 are fixedly installed on the bottom of both sides of the work box 4. Two pairs of parallel connecting rods 51 are rotatably installed between the wing plate 53 and the brake plate 15 on the same side. A pin 52 is rotatably installed between each pair of connecting rods 51. The crossbeam 3 is located between each pair of connecting rods 51, and the crossbeam 3 has an elongated hole for the pin 52 to pass through. When the crossbeam 3 moves up and down, the four pairs of connecting rods 51 at this point can swing simultaneously through the pin 52. The elongated hole is used to compensate for the horizontal displacement of the pin 52. The two pairs of parallel connecting rods 51 on each side can keep the brake plate 15 and the platform 6 in a parallel position relationship, ensuring the contact area of ​​the brake plate 15 during braking and also ensuring the strength of use.

[0031] Please see Figure 4 Each pin 52 is rotatably mounted with a roller 54, which is located inside the elongated hole. The rolling of the roller 54 reduces the friction of the pin 52 inside the elongated hole, thereby improving the smoothness of the movement.

[0032] Roller belts 12 are fixedly installed on both sides of the work box 4, and there are two roller belts 12 on each side distributed on the upper and lower parts of the platform 6. The roller belts 12 are components composed of an outer shell and multiple internal rotating rollers, which are used to reduce the resistance of the work box 4 moving in the guide groove 16.

[0033] Friction pads 14 are fixedly installed on the upper side of the brake plate 15, and friction strips 13 aligned with the friction pads 14 are fixedly installed on the bottom of the platform 6. The friction strips 13 and friction pads 14 are made of rubber, which can generate greater friction when they come into contact with each other to improve the braking effect. In addition, the length of the friction strip 13 is the same as the length of the guide groove 16, and the width of the friction strip 13 is at least 1.1 times that of the friction pads 14 to meet the contact requirements.

[0034] An extension plate 9 is fixedly installed at the top center of the opposing lead screw module 10, and universal balls 8 are evenly fixedly installed on the upper side of the extension plate 9. The extension plate 9 is used to increase the support area between the extension plate and the steel, improve the stability of the steel placement, and facilitate the clamping of the clamping plate 7. The universal balls 8 can facilitate the steel to move on the extension plate 9 when the clamping plate 7 is not clamping the steel, so as to facilitate the adjustment of the position.

[0035] The upper side of the platform 6 is provided with a scale band 17 along the guide groove 16; when the work box 4 moves along the guide groove 16, the position can be quickly determined according to the scale band 17, which facilitates the quick determination of the position.

[0036] The top of the platform 6 has screw holes 19 for installing support screws. The screw holes 19 are arranged in a rectangular and uniform array. Support screws can be screwed in at the required positions to support the steel and prevent the steel from tilting when it is clamped.

[0037] The push-pull electromagnet 2, the electrically driven worm gear rotary table 11, and the electrically driven opposing lead screw module 10, etc., are electrically connected to the external control cabinet and control panel.

[0038] The working principle of this embodiment:

[0039] In the initial state, the push-pull electromagnet 2 is in the initial position of the lower push beam 3. At this time, the friction belt 13 and the friction plate 14 are separated, and each pair of clamping plates 7 are in a position far away from each other.

[0040] For example Figure 6 For the welding requirements of steel butt joints, each work box 4 can be moved to the designated position along the scale band 17 according to the shape of the formed steel. The opposing lead screw module 10 is rotated by the worm gear rotary table 11, and each part of the steel can be placed on the extension plate 9 for alignment. If there are unstable supports, support screws can be added for auxiliary support. The push-pull electromagnet 2 pulls up the crossbeam 3, and after being transmitted by the transmission component 5, the friction plate 14 on the brake plate 15 can be pressed against the friction band 13 to complete the braking and positioning.

[0041] The opposing lead screw module 10 controls the opening and closing of each pair of clamping plates 7, which allows each piece of steel to be placed. After welding, the plates are flipped over to complete welding on the other side. The same shape of steel can be welded repeatedly with one adjustment.

[0042] When it is necessary to connect steel of other shapes, simply readjust the position of each work box 4 and the angle of the worm gear rotary table 11.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0044] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
