Description

Technical Field

[0001] The utility model relates to the technical field of laser welding machines, in particular to a spot laser square tube column weld. Background Art

[0002] Laser welding is a highly efficient and precise welding method that uses a laser beam with a high energy density as a heat source.

[0003] Spot laser square tube column weld refers to a streamer welding machine used to complete the welding of square tube columns. A square tube column refers to a tubular structure with a square cross-sectional shape. Usually, such workpieces are formed by bending sheets, and one of the edges is formed by welding. After welding, a square tube column with a square cross-sectional shape is obtained. Spot laser is a working mode of the streamer welding machine.

[0004] In the prior art, the square tube column is usually formed by a forming device for the sheet before welding. During the welding process, only the parts of the formed sheet that need to be welded need to be welded together. After welding, a weld is formed on the square tube column, and this weld can form one of the edge lines of the square tube column.

[0005] However, in the prior art, the positioning strength during the welding of the square tube column is low, and the parts to be welded are in a free state. That is, due to the elastic deformation of the square tube column itself, the position accuracy of the welding parts during the welding process is low, the opening width of the formed weld is uneven, resulting in low welding efficiency or poor welding quality.

[0006] Therefore, the laser welding equipment in the prior art has the technical problem that the fixing effect of the material to be welded is poor, resulting in low welding quality. Summary of the Invention

[0007] A spot laser square tube column weld provided by the utility model solves the technical problem that the fixing effect of the material to be welded of the laser welding equipment in the prior art is poor, resulting in low welding quality.

[0008] Some implementation schemes for solving the above technical problems include:

[0009] A spot laser square tube column weld includes a frame, and a welding component is arranged on the frame;

[0010] The frame is further provided with a feeding component for pushing the material to be welded to move relative to the welding component;

[0011] The frame is further provided with a supporting component for supporting and defining the shape of the material to be welded. There are two supporting components, and the welding component is located between the two supporting components;

[0012] The support assembly includes a base installed on the frame. The base is provided with a self-centering chuck. The self-centering chuck is provided with jaws. The jaws are provided with clamping grooves. The clamping grooves include side walls. There are two side walls, and each of the two side walls is provided with balls that respectively contact two walls of the material to be welded.

[0013] Preferably, the jaw includes a sliding seat. The sliding seat is provided with a jaw body that forms the side wall. The sliding seat and the jaw body are of an integral structure. Each sliding seat is provided with two jaw bodies, and the jaw body and the sliding seat are of an integral structure.

[0014] Preferably, the jaw body is provided with a mounting groove for mounting the balls. The depth of the mounting groove is greater than the radius of the mounting groove.

[0015] Preferably, grease is provided between the mounting groove and the balls. Each jaw body is provided with a plurality of balls, and the balls are evenly distributed on the side wall.

[0016] Preferably, each self-centering chuck is provided with four jaws, and the four jaws are evenly arranged along the circumferential direction of the self-centering chuck.

[0017] Preferably, the feeding assembly includes a slide table slidably connected to the frame. The frame is provided with a driver for driving the slide table to slide. The slide table is provided with a push tube that contacts the material to be welded.

[0018] Preferably, the slide table is provided with a vertical plate, and the push tube is arranged on the vertical plate in a detachable connection manner.

[0019] Preferably, the driver includes a motor installed on the frame. The frame is further provided with a lead screw and an optical rod. The slide table is provided with a threaded hole that cooperates with the lead screw and a light hole that cooperates with the optical rod. The lead screw is driven by the motor, and the lead screw is rotatably connected to the frame.

[0020] Preferably, the frame is further provided with a guide groove, and a part of the slide table is located in the guide groove.

[0021] Preferably, the frame is further provided with a fan for quickly cooling the welded material.

[0022] Compared with the prior art, the utility model has the following advantages:

[0023] 1. By setting up support components, and there are two support components, the welding component is located between the two support components. Both support components are used to support the material to be welded. Moreover, the support components can also define the shape of the material to be welded, so that during the welding process, the material to be welded has the correct relative position. And because the support components can define the shape of the material to be welded, the material to be welded has higher precision, thus improving the welding quality.

[0024] 2. By setting up a self-centering chuck, all the jaws on the self-centering chuck move simultaneously, making it easy to install the material to be welded on the support components and improving the tooling efficiency of the material to be welded. In addition, the jaws of the self-centering chuck move simultaneously, so that the shape of the material to be welded has higher precision.

[0025] 3. By setting up balls, the balls are in point contact with the material to be welded, and there is a smaller contact area between the balls and the material to be welded. Since the material to be welded needs to displace relative to the support components during the welding process, by setting up balls, the material to be welded and the jaws have rolling friction, and the chuck is not likely to damage the material to be welded.

[0039] The following detailed implementation modes are intended as descriptions of various configurations of the subject technology of the present utility model, and are not intended to represent the only configurations in which the subject technology of the present utility model can be practiced. The detailed implementation modes include specific details intended to provide a thorough understanding of the subject technology of the present utility model. However, it will be clear and obvious to those skilled in the art that the subject technology of the present utility model is not limited to the specific details shown herein, and can be practiced without these specific details.

[0040] It can be understood that in this article, relational terms such as "first" and "second" are intended to distinguish one entity or operation from another entity or operation, and are not intended to explicitly or implicitly imply any actual relationship or order between these entities or operations.

[0041] The term "comprising", "including" or any other variant thereof is intended to cover non - exclusive inclusion, such that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including one..." does not exclude the presence of additional identical elements in the process, method, article or device including the said element.

[0042] Refer to Figures 1 to 6 As shown, a spot laser welding for square tube columns includes a frame 1, and a welding component 2 is provided on the frame 1;

[0043] The frame 1 is further provided with a feeding component 3 for pushing the material to be welded to move relative to the welding component 2;

[0044] The frame 1 is further provided with a support component 4 for supporting and defining the shape of the material to be welded. There are two support components 4, and the welding component 2 is located between the two support components 4;

[0045] The support assembly 4 includes a base 41 installed on the frame 1. The base 41 is provided with a self-centering chuck 42. The self-centering chuck 42 is provided with jaws 5. The jaws 5 are provided with a slot 51. The slot 51 includes side walls. There are two side walls, and both of the two side walls are provided with balls 52 that respectively contact two walls of the material to be welded.

[0046] In some embodiments, since the material to be welded has been formed by the forming device before welding, that is, the self-centering chuck 42 is mainly used to support the material to be welded. While supporting the material to be welded, the jaws 5 provide a certain clamping force, so that the welding part of the formed material to be welded has a smaller gap, thereby improving the welding efficiency and welding quality.

[0047] Therefore, the material to be welded does not require the support assembly 4 to provide a clamping force with high precision to maintain its shape. That is to say, using the chuck of the self-centering chuck 42 to clamp materials with a cross-section in a square or regular polygon shape can fully meet the welding requirements.

[0048] In some embodiments, the jaw 5 includes a sliding seat 53. The sliding seat 53 is provided with a jaw body 531 that forms the side wall. The sliding seat 53 and the jaw body 531 are of an integral structure.

[0049] The self-centering chuck 42 is provided with end face threads. Each sliding seat 53 is provided with mating threads that cooperate with the end face threads. During the rotation of the end face threads, all the sliding seats 53 are driven to move simultaneously. The working principle of the self-centering chuck 42 refers to the prior art.

[0050] In some embodiments, the jaw body 531 is provided with an installation groove for installing the ball 52, and the depth of the installation groove is greater than the radius of the installation groove.

[0051] A lubricating grease is provided between the installation groove and the ball 52. Each jaw body 531 is provided with a plurality of balls 52, and the balls 52 are evenly distributed on the side wall.

[0052] The ball 52 can be assembled into the installation groove by a hot assembly method. The size of the ball 52 is not limited in quantity and can be reasonably determined according to needs.

[0053] The ball 52 enables rolling friction between the jaw body 531 and the material to be contacted, which can prevent the jaw body 531 from damaging the material to be welded.

[0054] In some embodiments, each self-centering chuck 42 is provided with four jaws 5, and the four jaws 5 are evenly arranged along the circumferential direction of the self-centering chuck 42.

[0055] The base 41 of the support component 4 can be fixed to the frame 1 by screws.

[0056] The welding component 2 is a laser welding machine.

[0058] The sliding table is provided with a vertical plate 31, and the pushing tube 32 is arranged on the vertical plate 31 in a detachable connection manner. The vertical plate 31 and the sliding table can be an integral structure, or the vertical plate 31 can also be welded to the sliding table, or the vertical plate 31 can also be fixed to the sliding table by screws.

[0059] In some embodiments, the driver includes a motor installed on the frame 1. The frame 1 is further provided with a lead screw and an optical rod. The sliding table is provided with a threaded hole cooperating with the lead screw and an optical hole cooperating with the optical rod. The lead screw is driven by the motor and is rotatably connected to the frame 1. The motor can be fixed to the frame 1 by screws.

[0060] In some embodiments, the frame 1 is further provided with a guiding groove 33, and a part of the sliding table is located in the guiding groove 33.

[0061] The guiding groove 33 can penetrate through the frame 1, and both the lead screw and the optical rod can be arranged below the tabletop of the frame 1 so that there is a larger space on the tabletop of the frame 1 to place or arrange other structures.

[0062] In some embodiments, the frame 1 is further provided with a fan for quickly cooling the welded material.

[0063] The fan enables air to quickly flow through the welded material, so that the welded material can be quickly cooled down.

[0064] In some embodiments, the welding component 2 can be installed on the frame 1 through a bracket. The bracket can be fixed to the frame 1 by screws, and the welding component 2 can be fixed to the bracket by screws. The welding component 2 is a common laser welding machine in the prior art.

[0065] The above introduces the technical solutions of the subject matter of the present invention and the corresponding details.
