[0002] Support frame workpieces are often used as base components. They usually use a number of rods or pipes that are connected to each other to form a three-dimensional support frame body. In the process of processing the support frame, welding is a more commonly used connection method, which can make the support frame more stable and firm.

[0003] In the welding process of the support frame, multiple rods or pipes need to be arranged and connected in six directions: front, back, left, right, up and down, so as to form the frame of the support frame. Figure 1 As shown, the support frame 1 is usually provided with a plurality of mutually parallel cross beams 11, legs 12 bent downward at both ends of the cross beams 11, and ears 13 provided at the ends of the legs 12, so as to be able to support or serve as a base component, and to weld the rods or pipes at the positions where they are butted together, thereby completing the welding work of the support frame. At present, in many processing factories, it is usually a method of manually holding pipes or rods for alignment, and the rods are sequentially welded to the semi-finished workpiece to be welded, thereby completing the welding work of the support frame.

[0004] However, the above processing method relies too much on manual welding, which makes the labor intensity of the operators higher and the welding efficiency lower.

[0005] Therefore, there is an urgent need for a welding device that can weld the support frame workpiece. Utility Model Content

[0026] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0027] It should be noted that in the embodiments of the present utility model, all directional indications (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0028] In addition, the descriptions of “first”, “second”, etc. in the embodiments of the present invention are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features.

[0029] The embodiment of the utility model provides a support frame welding device, which can support and press rods or pipes during the welding process of the support frame body 10, and after forming the frame of the support frame body 10, it is convenient for the welding robot 100 to perform welding processing on the joints between the rods or pipes, thereby replacing the manual hand-held docking and positioning processing method, reducing the degree of manual participation and workload, and improving production efficiency.

[0030] In a support frame welding device provided in an embodiment of the utility model, as Figure 2-7As shown, it includes a welding robot 100 and a welding fixture 200 for supporting and positioning a workpiece. In this embodiment, the welding fixture 200 includes a welding plate 201, a support rod 210 and a pressing mechanism 220, wherein the support rod 210 has a plurality of support positions arranged at predetermined positions and are all fixedly mounted on the welding plate 201. The support rod 210 is provided with a support position 211 for supporting the workpiece. When welding the support frame 10, the rod or pipe to be welded is horizontally arranged and supported by the support position 211 on the support rod 210, thereby maintaining a horizontally arranged state. The pressing mechanism 220 is provided with a plurality of support positions 211 for holding the workpiece. The parts are pressed downward within the support position 211, and the pressing mechanism 220 includes a mounting rod 221 fixedly mounted on the welding plate 201, and a pressing fixture 222 is fixedly mounted on the mounting rod 221. The pressing fixture 222 includes a base 2221 fixedly mounted on the end of the mounting rod 221, and a toggle rod 2222 and a clamping arm 2223 are rotatably connected to the base 2221, and the rotating axes of the toggle rod 2222 and the clamping arm 2223 are parallel to each other. The pressing fixture 222 also includes a connecting rod 2224, one end of the connecting rod 2224 is rotatably connected to the middle section of the toggle rod 2222, and the other end is rotatably connected to the middle section of the clamping arm 2223.

[0031] Specifically, in the process of pressing down and fixing the rod or pipe to be welded, the clamping arm 2223 is driven to swing by swinging the toggle rod 2222, so that one end of the clamping arm 2223 moves downward to press down the rod or pipe to be welded located on the lower side thereof, thereby clamping it on the support position 211.

[0032] At the same time, the above-mentioned technical scheme can fix multiple rods or pipes to be welded, and directly assemble and align them with each other, so as to facilitate the welding robot 100 to weld the joints of the aligned and assembled pipes to be welded, and complete the welding work of the support frame 10. In the technical scheme provided in this embodiment, during the welding of the support frame 10, the welding tool 200 is used to align and clamp the workpieces to be welded, avoiding the operator's hand-held alignment operation, which can reduce the operator's participation in the welding process, reduce labor intensity, and improve welding efficiency.

[0033] In this embodiment, if Figure 6-7As shown, a pressing block is formed on the connecting rod 2224. When the toggle rod 2222 swings toward the clamping arm, the pressing block and the clamping arm abut against each other. The swinging toggle rod 2222 drives the clamping arm 2223 to swing through the connecting rod 2224, so that the end of the clamping arm 2223 flips downward. At this time, the low-pressure block 2225 on the connecting rod 2224 contacts and presses the side of the clamping arm 2223, so that downward pressure can be applied to the clamping arm 2223, thereby increasing the clamping force on the workpiece to be welded. It can be imagined that when the toggle rod 2222 and the connecting rod 2224 are in the same straight line, the toggle rod 2222 is in a dead point position, and the dead point position can make the clamping arm 2223 stably in a tightened state, and can prevent the welded workpiece from falling off due to unstable tightening.

[0034] In this embodiment, if Figure 3-5 As shown, a support seat 230 is fixedly arranged on the welding plate 201. The support seat 230 is provided with multiple parts adapted to the workpiece and used to support the part of the workpiece extending toward the welding plate 201. A slot 231 adapted to the lower end of the workpiece is opened on the top of the support seat 230, and a linkage platform 232 is arranged beside the slot 231, and a positioning column 233 is formed on the linkage platform 232.

[0035] The pipe or rod to be welded has a transversely arranged beam 11 and legs 12 bent downward at both ends of the beam 11. The support seat 230 is used to support the legs 12 of the workpiece to be welded, thereby ensuring that the legs 12 of the workpiece to be welded will not shake, and will not cause the clamped part of the beam 11 to rotate, providing stability for the supported and tightened workpiece to be welded. In the process of supporting the workpiece to be welded, the legs 12 of the workpiece are arranged in the slot. At the same time, the linkage table 232 is used to carry the ears 13 to be welded on the legs 12 of the workpiece, and the ears 13 are fixed by positioning columns 233.

[0036] like Figure 5As shown, in this embodiment, the slot 231 is set as an open structure, which has an opening toward the linkage platform 232, and the side wall of the slot 231 away from the linkage platform 232 defines a limiting portion 234 for limiting the lower end of the workpiece. When the workpiece to be welded is installed on the welding fixture 200, since there may be multiple beams 11 in most cases that are arranged side by side in the upper and lower directions, the support positions 211 may also be arranged side by side in the upper and lower directions. At this time, the support position 211 is usually arranged on a cantilever extending in the radial direction of the support rod 210. Therefore, when the leg 12 of the workpiece to be welded is placed in the slot 231, the leg 12 of the workpiece to be welded is placed in the slot 231 through the opening of the slot 231, which can facilitate the installation of the workpiece to be welded. At the same time, after the welding of the support frame 10 is completed, the support frame 10 can also be removed from the welding fixture 200 by moving it laterally, or the welded support frame 10 can be removed from the welding fixture 200 by lifting it upward slightly and then moving it laterally.

[0037] In this embodiment, if Figure 5 As shown, in order to more stably position and fix the leg 12 of the workpiece to be welded, a positioning boss 235 protruding upward for positioning the lower end of the workpiece is formed at the bottom of the slot 231, and the longitudinal section of the positioning boss 235 is a conical or truncated cone structure. Therefore, when the leg 12 of the workpiece to be welded is placed in the slot 231, the positioning boss 235 at the bottom of the slot 231 is embedded in the circular hole of the workpiece to be welded, thereby ensuring the stability of the workpiece to be welded.

[0038] In this embodiment, in order to ensure the stability of the tightening of the cross beam 11 of the workpiece to be welded, the support position 211 is provided with a support groove 2111 opened on the support rod 210. Figure 4 As shown, a hole 2112 is provided on at least one side wall of the support groove 2111, and a fastener for locking the workpiece in the support groove 2111 is installed in the hole 2112. Since the width of the support groove 2111 is greater than the width of the cross beam 11 of the workpiece to be welded, after the cross beam 11 is placed in the support groove 2111, the position of the cross beam 11 in the support groove 2111 is in a movable state, so it is not convenient for the clamping arm 2223 to clamp and fix it. The fastener passes through the hole 2112, so that the cross beam 11 is fixed in advance in the support groove 2111, so that the position of the cross beam 11 in the support groove 2111 is determined, so that it is convenient for the clamping arm 2223 to clamp the workpiece to be welded. In this embodiment, the fastener is a bolt, and an internal thread connected to the bolt thread is provided inside the hole 2112. After the bolt is screwed in, it contacts the side wall of the workpiece to be welded, thereby fixing the crossbeam 11 of the workpiece to be welded together with the inner wall of the support groove 2111.

[0039] The embodiment of the utility model provides a support frame welding device, which stably clamps the workpieces to be welded through the support rod 210 and the pressing mechanism 220 and aligns them with each other, so that it is convenient for the welding robot 100 to weld the docking position of the workpieces, and avoids the situation of manually holding the workpieces to be welded for aligning and welding during the welding process, which greatly reduces the labor intensity of workers and improves welding efficiency.

[0040] For those skilled in the art, various other corresponding changes and deformations can be obtained according to the structure and principle disclosed by the utility model, and all of these changes and deformations belong to the protection scope of the utility model.
