Description

Technical Field

[0001] This utility model relates to the field of hinge manufacturing technology, and in particular, to a hinge laser welding device. Background Technology

[0002] A hinge is a mechanical device used to connect two solid objects (such as doors, windows, and cabinets), allowing them to rotate relative to each other to achieve an opening and closing function. Hinges can be classified by material, including stainless steel, zinc alloy, and iron, and their surfaces are often coated or polished to enhance durability. They are widely used in furniture (such as cabinets and wardrobes), building doors and windows, and industrial equipment.

[0003] The hinge plate is made up of a connecting plate and a bushing welded together. For example, the welding work is usually done by manually holding the connecting plate and the bushing together. However, this method depends on the experience of the operator and is prone to uneven welding quality. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a hinge laser welding device.

[0005] The objective of this utility model is achieved through the following technical solution: A hinge laser welding device includes a frame, a clamping seat on the frame, an arc-shaped groove for placing a bushing on the clamping seat, a clamping member on the clamping seat opposite to the arc-shaped groove, a clamping groove on the clamping member for engaging a connecting plate, and an ejector on the clamping seat for pushing the end of the connecting plate in the clamping groove against the bushing in the arc-shaped groove.

[0006] Preferably, the ejector includes a cylinder.

[0007] Preferably, the frame is provided with a transfer component, the clamping seat is provided on the transfer end of the transfer component, and a plurality of clamping seats are provided at intervals along the transfer direction of the transfer end; a welding machine is provided on the frame located on the transfer path of the transfer end.

[0008] Preferably, the transfer component includes a rotary table, and the rotating disk of the rotary table constitutes the transfer end.

[0009] Preferably, a connecting frame is provided on the clamping seat at the end of the arc-shaped groove, the clamping member is provided on the side wall of the connecting frame, and a positioning groove is provided through the side wall of the connecting frame. The clamping member includes two clamping units respectively disposed on both sides of the positioning groove, so that the clamping groove is aligned with the positioning groove. The positioning groove is adapted to allow the narrow part of the connecting plate to pass through, while the wide part of the connecting plate is stopped by the connecting frame.

[0010] Preferably, the side wall of the connecting frame is further provided with a mounting plate, and the ejector is disposed on the mounting plate.

[0011] Preferably, the transfer component includes a sliding table, and the slide base of the sliding table is configured as the transfer end.

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] like Figures 1 to 4 As shown, a hinge laser welding device includes a frame 1, a clamping seat 2 mounted on the frame 1, an arc-shaped groove 3 formed on the end face of the clamping seat 2, and a connecting frame 9 also mounted on the end face of the clamping seat 2. The connecting frame 9 has an ejector 6 and a clamping member 4 arranged from top to bottom on the connecting frame 9. The clamping member 4 is vertically opposite to the arc-shaped groove 3, and the clamping member 4 also has a clamping groove 5.

[0020] During welding, the bushing 20 is first placed into the arc-shaped groove 3, and then the connecting plate is inserted into the clamping groove 5, so that the bottom end of the connecting plate initially overlaps with the bushing 20. Next, the ejector 6 is controlled to perform an ejection action. For example, the ejector 6 may include a cylinder and a pressure plate mounted on the output shaft of the cylinder. The pressure plate pushes the connecting plate downwards, further pressing its end against the bushing 20. At this point, the operator can use a handheld welding torch or the welding machine 8 described below to complete the welding at the joint between the bushing 20 and the connecting plate.

[0021] In a preferred example, both the arc-shaped groove 3 and the clamping groove 5 are configured as openings in the lateral direction, so that the operator can easily insert the bushing 20 into the arc-shaped groove 3 from the side and insert the connecting plate into the clamping groove 5 from the side.

[0022] The connecting frame 9 is specifically adapted to be located at the end of the arc-shaped groove 3, meaning that the lateral snap-in action of the connecting plate and bushing 20 can be seen as gradually approaching the connecting frame 9. The clamping member 4 is correspondingly located on the side wall of the connecting frame 9. A positioning groove 10 is provided through the side wall of the connecting frame 9, and the clamping member 4 specifically includes two clamping units 11 located on both sides of the positioning groove 10. The positioning groove 10 is defined between the two clamping units 11, which also makes the clamping groove 5 aligned with the positioning groove 10.

[0023] For example, after the connecting plate is inserted into the positioning groove 10 in any direction, the connecting plate can be pushed further towards the connecting frame 9. At this time, the narrow part of the connecting plate will pass through the positioning groove 10, while the wide part of the connecting plate will be stopped by the connecting frame 9, thereby achieving the axial positioning of the connecting plate.

[0024] In a specific example, a mounting plate 12 may be provided on the top of the side wall of the connecting frame 9, and the aforementioned ejector 6 is provided on the mounting plate 12.

[0025] For example, the clamping unit 11 may specifically include clamping blocks 18, and the opposite sides of the two clamping blocks 18 are both constructed as clamping planes. It can be understood that the two clamping planes can define the aforementioned positioning groove 10. As another configuration, the clamping unit 11 may include a clamping roller 17 rotatably connected to the connecting frame 9, in which case the positioning groove 10 is defined between the two clamping tubes.

[0026] The clamping rollers 17 are also adapted to have different diameters in the circumferential direction. For example, when the thickness of the connecting plate to be welded is adjusted, the two clamping rollers 17 can be rotated to change the width of the positioning groove 10. In a preferred example, the diameter change of the clamping tube in the circumferential direction is uniform; for example, when the two clamping rollers 17 are rotated clockwise, the width of the positioning groove 10 gradually increases; while when the two clamping rollers 17 are rotated counterclockwise, the width of the positioning groove 10 gradually decreases.

[0027] In some embodiments, the frame 1 may preferably be provided with a transfer component 7, and a clamping seat 2 is provided on the transfer end of the transfer component 7, and several are spaced apart along the transfer direction of the transfer end. In addition, the frame 1 is also provided with a welding machine 8 on the transfer path located at the transfer end. The operator can first clamp the bushing 20 and the connecting plate in sequence on the first clamping seat 2, and then the transfer end can be transferred from the first clamping seat 2 to be opposite to the welding machine 8, so that the welding machine 8 can automatically complete the welding of the joint of the bushing 20 and the connecting plate; at the same time, the operator can clamp the bushing 20 and the connecting plate in the same way on the second clamping seat 2, so as to realize the semi-automatic welding of the hinge in a cycle.

[0028] In a possible example, the transfer component 7 can be a rotary table, in which case the rotary table's rotating disk is configured as the transfer end described above. A plurality of clamping seats 2 are arranged circumferentially on the rotary disk. Based on the rotation of the rotary disk at a preset angle, the clamping seats 2 can be transferred to the welding position of the welding machine 8.

[0029] Alternatively, the transfer component 7 can be a sliding table (not shown). For example, the sliding table can be driven by a linear module to transfer the slide along a linear direction, and several clamping seats 2 are arranged longitudinally at intervals on the slide. Similarly, the bushing 20 and the connecting plate can be inserted into the clamping table of the slide in sequence. After the last clamping seat 2 is opposite to the welding machine 8 and welding is completed, the slide can be controlled to slide back to the initial position, and this process can be repeated to achieve semi-automatic welding of the hinge.

[0030] In some embodiments, a detection block 13 may also be provided on the frame 1, and a detection groove 14 is provided on the end face of the detection block 13. For example, the detection groove 14 is adapted to accommodate the placement of the welded finished product, and may specifically include a connected circular hole portion 15 and a plate groove portion 16. It can be understood that, based on the position of the plate groove portion 16 relative to the circular hole portion 15, when the welded finished product can be smoothly placed into the detection groove 14, the welding can be determined to be qualified, and when the welded finished product cannot be smoothly placed into the detection groove 14, the welding can be determined to be unqualified, thereby enabling timely detection of unqualified products.

[0031] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
