Description

Technical Field

[0001] This utility model relates to the field of space frame processing technology, specifically to a space frame welding device. Background Technology

[0002] The space frame is typically welded from high-temperature resistant metal wires, such as nickel-chromium wire or stainless steel wire. Its main function is to provide mechanical support and structural fixation. The space frame serves as a skeleton, with mica sheets covering or clamping both sides (or one side) of the frame. Heating wires are wound around the space frame and sandwiched between two layers of mica sheets, or passed through grooves in the mica sheets before being wound around the frame. In this way, the heating wires are firmly fixed to the structure provided by the space frame, while their charged parts are completely encased or isolated by the mica sheets, preventing them from contacting the metal space frame or outer shell.

[0003] Existing space frames are usually formed by welding together several groups of vertically arranged and horizontally arranged metal rods at equal intervals. Before welding, several groups of metal rods need to be manually loaded and arranged into the welding box. Then, the intersections of the metal rods are welded and fixed by welding equipment. Manual loading is cumbersome and difficult to apply to the mass production of space frames. Utility Model Content

Detailed Implementation

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1 Please see Figures 1-2 As shown, this utility model is a space frame welding equipment, including a workbench 1, a turntable 2 rotatably arranged on the workbench 1, a servo motor fixedly arranged at the bottom of the workbench 1, and the drive end of the servo motor fixed to the turntable 2; specifically, in this embodiment, the turntable 2 can be driven to rotate circumferentially on the workbench 1 by the servo motor. In this embodiment, several sets of positioning boxes 3 are fixedly arranged in a circumferential array on the turntable 2 to arrange the metal rods into a grid structure; specifically, in this embodiment, before welding the metal rods, several sets of metal rods are first arranged in the positioning boxes 3 to form a grid structure (see reference). Figure 4 ); As a further embodiment, the workbench 1 on the outer side of the turntable 2 is provided with a first loading section 4, a second loading section 5, a welding section 6 and a unloading section 7 arranged in a circumferential direction. The first feeding part 4 is used to arrange the first layer of metal rods in the positioning box 3, the second feeding part 5 is used to arrange the second layer of metal rods on the first layer of metal rods, and the arrangement directions of the first layer of metal rods and the second layer of metal rods are perpendicular, the welding part 6 is used to weld and fix the first layer of metal rods and the second layer of metal rods, and the unloading part 7 is used to remove the welded grid structure from the positioning box 3. It can be explained that, in the initial state, the positioning box 3 is rotated to the first loading section 4 by the turntable 2. The first loading section 4 first arranges several sets of metal rods vertically in the positioning box 3. As the turntable 2 continues to rotate, the positioning box 3 is rotated to the position of the second loading section 5. The second loading section 5 arranges several sets of metal rods horizontally in the positioning box 3, which intersects perpendicularly with the vertically arranged metal rods to form a grid-like structure. Next, the positioning box 3 is rotated to the welding section 6 by the turntable 2. The welding section 6 welds the intersections of the metal rods. After welding, the turntable 2 rotates the positioning box 3 to the unloading section 7 to unload the welded grid structure. Based on this, this embodiment sets multiple positioning boxes 3 on the turntable 2, so that the first loading section 4, the second loading section 5, the welding section 6, and the unloading section 7 can perform the corresponding processes simultaneously without affecting each other. This can effectively improve the loading, welding, and unloading efficiency of the grid structure, and eliminates the need for manual processing, resulting in a higher degree of automation.

[0021] Furthermore, in this embodiment, six sets of positioning boxes 3 are arranged circumferentially on the turntable 2. Correspondingly, the turntable 2 may also be provided with other numbers of sets. This embodiment does not limit this, as long as it meets the actual application requirements.

[0022] It should also be noted that welding equipment is provided at the welding section 6 in this embodiment for welding the contact ends of the first layer metal rod and the second layer metal rod. The welding equipment in this embodiment adopts existing technology, and its specific structure and model are not limited in this embodiment.

[0023] Example 2 Based on Embodiment 1, the first feeding section 4 includes a first storage box 201 fixedly arranged on the workbench 1 for storing metal rods, and the second feeding section 5 includes a second storage box 202 fixedly arranged on the workbench 1 for storing metal rods. The first storage box 201 and the second storage box 202 are provided with feeding modules for feeding several groups of metal rods one by one. It can be noted that in this embodiment, before feeding the metal rods, several groups of metal rods are first stored in the first storage box 201 and the second storage box 202. When the turntable 2 drives the positioning box 3 to move to the position of the first feeding section 4 or the second feeding section 5, the feeding module pushes out the metal rods one by one to facilitate feeding.

[0024] In this embodiment, please refer to Figure 3 as well as Figure 6The feeding module includes a storage cavity 204 located in a storage box. Several sets of feeding plates 205 for outputting metal rods are arranged in the storage cavity 204. The feeding plates 205 have arc-shaped grooves 207 for embedding metal rods. The feeding module also includes a lifting part for driving the feeding plates 205 to rise and fall vertically. It can be noted that in this embodiment, several sets of metal rods are stacked and stored in the storage cavity 204. In the initial state, the feeding plates 205 are located at the bottom of the storage cavity 204. When feeding is required, the feeding plates 205 are driven to rise by the lifting part. During the rising process, some metal rods will be stuck in the arc-shaped grooves 207 and can then rise with the feeding plates 205 to the top of the storage cavity 204 for subsequent feeding.

[0025] Accordingly, in this embodiment, you can refer to Figures 3-4 The grid structure of this embodiment includes a first layer of metal rods, with two sets of the first layer of metal rods arranged in two corresponding sets of feeding plates 205 in the first storage box 201. The second layer of metal rods has five sets of feeding plates 205 arranged in five corresponding sets in the second storage box 202. Specifically, by setting a number of feeding plates 205 corresponding to each layer of metal rods, the metal rods to be fed can be accurately pushed out each time they are fed.

[0026] As one possible implementation of this embodiment, a conical cavity 206 is provided at the bottom of the storage cavity 204, and the bottom of the conical cavity 206 is connected to the guide groove 209 for slidingly embedding into the feed plate 205. It can be explained that by providing the conical cavity 206, the metal rod placed in the storage cavity 204 can be gathered in the direction of the guide groove 209, and the arc groove 207 of the feed plate 205 is lowered to the guide groove 209, so that the metal rod can accurately fall into the arc groove 207.

[0027] In addition, the lifting unit includes a lifting cylinder or lifting electric cylinder fixedly arranged at the bottom of the guide groove 209, and its driving end is fixed to the loading plate 205; specifically, in this embodiment, the loading plate 205 can be driven to rise and fall along the guide groove 209 by the lifting cylinder or lifting electric cylinder.

[0028] In this embodiment, please refer to Figures 1-2 as well as Figure 5The first feeding section 4, the second feeding section 5, and the unloading section 7 all include a clamping section, which is used to clamp the metal rod pushed out of the storage chamber 204 by the feeding section. The clamping section includes an adjusting electric cylinder 401, the driving end of the adjusting electric cylinder 401 is fixed to the lifting plate 402, and the two ends of the lifting plate 402 away from the adjusting electric cylinder 401 are respectively fixedly and symmetrically arranged with clamping electric cylinders 403. The driving ends of the clamping electric cylinders 403 are respectively fixedly and symmetrically arranged with two sets of grippers 404. It can be noted that after the metal rod is pushed out by the feeding plate 205 in this embodiment, the adjusting electric cylinder 401 can drive the lifting plate 402 to descend to the corresponding height, so that the clamping electric cylinders 403 can drive the two sides of the grippers 404 to move closer to each other, thereby achieving the effect of clamping the metal rod.

[0029] In addition, the first loading section 4, the second loading section 5, and the unloading section 7 also include a translation mechanism 203. The drive end of the translation mechanism 203 is fixed to the adjusting electric cylinder 401. It can be explained that after the gripper 404 grips the metal rod, the translation mechanism 203 can drive the gripped metal rod to translate, so as to move the metal rod. For the loading section 7, the metal rod can be transferred to the positioning box 3. For the unloading section, the welded grid structure can be removed from the positioning box 3.

[0030] Specifically, the translation mechanism 203 can adopt the synchronous belt drive mechanism in the prior art. This embodiment does not limit its specific structure and model.

[0031] For easier clamping of the metal rods protruding from the feed plate 205, please refer to... Figure 3 The feeding plate 205 has a reserved groove 208. The opening position of the reserved groove 208 corresponds to the clamping position of the gripper 404, so as to facilitate the clamping of the metal rod and avoid interference.

[0032] Please see Figure 4 To position the metal rod in the positioning box 3, at least two sets of first positioning plates 502 are fixedly arranged at intervals in the positioning box 3. The first positioning plates 502 have first grooves 501 for embedding the first layer of metal rods. The positioning box 3 also has two sets of second positioning plates 503 fixedly arranged at intervals. The second positioning plates 503 have second grooves 504 for embedding the second layer of metal rods. It can be noted that when the metal rod in this embodiment is placed in the positioning box 3, the first layer of metal rod can be placed in the first groove 501 of the first positioning plate 502, and the second layer of metal rod can be placed in the second groove 504 of the second positioning plate 503. The first positioning plate 502 and the second positioning plate 503 are arranged perpendicularly. After placement, the first layer of metal rod and the second metal rod are in contact to facilitate subsequent welding.

[0033] A welding method for a space frame welding device includes the following steps: Please see Figures 1-4 S1, the servo motor can drive the turntable 2 to rotate circumferentially on the worktable 1, and the turntable 2 rotates the positioning box 3 to the first feeding part 4. The first feeding part 4 first arranges several groups of metal rods vertically in the positioning box 3. S2. As the turntable 2 continues to rotate, the positioning box 3 is rotated to the position of the second feeding part 5. The second feeding part 5 arranges several groups of metal rods horizontally in the positioning box 3 and intersects them perpendicularly with the vertically arranged metal rods to form a grid structure. S3, the turntable 2 rotates the positioning box 3 to the welding part 6, and the welding part 6 welds the intersection of each metal rod; S4. After welding is completed, the turntable 2 rotates the positioning box 3 to the unloading section 7 to unload the welded space frame structure.
