Description

Technical Field

[0001] This utility model relates to the field of prefabricated building component production technology, and in particular to a welding device for processing prefabricated building components. Background Technology

[0002] Composite slabs, as an important component of modern prefabricated buildings, are widely used in building floors, walls, and other structures. Their production process involves fixing prefabricated steel trusses to the base slab reinforcement at designed intervals, followed by concrete pouring. The steel trusses enhance the structural rigidity and load-bearing capacity. A typical steel truss consists of top chord reinforcement, bottom chord reinforcement, and web reinforcement connecting them, welded together to form a triangular unit frame structure. (Specific details are omitted as they are not directly related to the preceding text.) Figure 1 As shown, A-bottom chord reinforcement, B-web reinforcement, and C-top chord reinforcement. The steel truss structure not only effectively improves the overall performance of the composite slab, but also facilitates transportation and installation, greatly promoting the development of industrialized construction.

[0003] In the process of realizing this invention, the inventors discovered at least the following problems in the prior art:

[0004] In traditional welding processes, the welding of steel trusses in composite slabs is mostly done manually in sections. This method first requires assembling the top chord steel bars with two prefabricated steel skeletons (which are pre-welded together from the bottom chord steel bars and several web steel bars). However, manual support and fixation alone often cannot guarantee the precise positioning between the two steel skeletons. This positioning deviation will be further amplified in the subsequent welding process, resulting in significant dimensional and shape deviations in the welded steel truss, and even affecting the structural strength and installation accuracy of the entire composite slab. In addition, manual welding is time-consuming and cannot meet the needs of high-efficiency industrial production.

[0005] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, this utility model proposes a welding device for processing prefabricated building components, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows:

[0008] A welding device for processing precast building components includes a tooling mechanism for positioning and assembling an upper chord reinforcing bar and two reinforcing bar cages, and a welding mechanism for welding the positioned upper chord reinforcing bar to the two reinforcing bar cages.

[0009] The tooling mechanism includes a base plate and two symmetrically distributed support components located on opposite sides of the top of the base plate, as well as a positioning component located outside one of the support components. Each support component consists of a mounting base, a support member for mounting the end of the upper chord reinforcing bar, and two U-shaped slots for mounting the end of the lower chord reinforcing bar. The support member is located in the center of the inner side of the top of the mounting base, and the two support members are symmetrically arranged on opposite sides of the support member and both located on the outer side of the top of the mounting base. The positioning component includes a fixing plate vertically mounted to one side of the top of the base plate by a first bolt. Two sleeves for fitting and accommodating the ends of the lower chord reinforcing bars are vertically welded to the top of the inner side of the fixing plate. Each sleeve has a locking screw threaded vertically through its top.

[0010] The welding mechanism includes a vertical plate fixedly connected to the back of the base plate and a slide table horizontally mounted on the front of the vertical plate, as well as a cylinder fixedly installed on the slide table slide seat. The output end of the cylinder is fixedly mounted with a laser welding gun suspended directly above the upper chord steel bar through a connecting plate.

[0011] Preferably, the support member includes a support and a V-shaped groove block slidably fitted onto its upper part. The inner sides of the V-shaped groove block and the support are respectively provided with a first extended side and a second extended side. An adjusting screw is vertically threaded through the second extended side, and the top end of the adjusting screw passes through the first extended side and is rotatably connected to the first extended side. The support member is used for end support of the upper chord reinforcing bar. Specifically, the design of the V-shaped groove block facilitates the clamping of the upper chord reinforcing bar end, while the design of the adjusting screw facilitates fine-tuning of the height of the V-shaped groove, ensuring precise positioning of the upper chord reinforcing bar.

[0012] Preferably, the support and the two U-shaped groove blocks are all fixedly connected to the mounting base by the second bolts. The mounting base consists of a pad, two parallel T-slots on the top of the pad that accommodate the heads of the second bolts, and two sealing plates respectively covering the front and rear sides of the pad. The mounting base provides a foundation for the support and the U-shaped groove blocks, while the design of the T-slots and the second bolts facilitates fine-tuning of the positions of the support and the U-shaped groove blocks, as well as subsequent easy disassembly and maintenance.

[0013] Preferably, the two sealing plates are symmetrically distributed and both have an L-shaped structure. Both sealing plates are fixedly connected to the base plate by a third bolt. The base plate has four strip-shaped holes arranged in a rectangular array along its length, and each of the four strip-shaped holes is adapted to the third bolt. The base plate serves as the supporting foundation for the entire tooling mechanism, providing a stable installation platform. The easy-to-disassemble design of the strip-shaped holes and the third bolt facilitates the adjustment of the spacing between the two supporting components to accommodate positioning tooling for steel trusses of different lengths.

[0014] Preferably, the U-shaped groove has flared structures on both sides of the groove opening. The U-shaped groove is used to hold the end of the lower chord reinforcing bar, and the flared structure facilitates quick alignment and installation of the lower chord reinforcing bar end.

[0015] The beneficial effects of this utility model are:

[0016] The technical solution of this utility model, by setting up a tooling mechanism and with the help of two support members and the cooperation of the positioning component, can achieve high-precision positioning between the upper chord steel bar and the two steel bar skeletons, effectively reducing the size and shape deviation after welding. At the same time, by adopting laser welding technology and combining the automated action driven by cylinders and slides, the welding efficiency is significantly improved, the production cycle is shortened, and the needs of high-efficiency industrial production are met.

[0037] 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.

[0038] Please see Figures 1-9This utility model provides a technical solution: a welding device for processing precast building components, including a tooling mechanism 100 for positioning and assembling upper chord reinforcing bars and two reinforcing bar skeletons, and a welding mechanism 200 for welding the positioned upper chord reinforcing bars to the two reinforcing bar skeletons. The tooling mechanism 100 includes a base plate 110 and two support components 120 symmetrically distributed on both sides of the top of the base plate 110, and a positioning component 130 located outside one of the support components 120. The support component 120 consists of a mounting base 1210, a support member 1220 for clamping the end of the upper chord reinforcing bar, and two U-shaped groove blocks 1230 for clamping the end of the lower chord reinforcing bars. The support member 1220 is located in the middle of the inner side of the top of the mounting base 1210, and the two support members 1220 are symmetrically distributed. The positioning components 130 are respectively located on both sides of the support member 1220 and on the outer side of the top of the mounting base 1210. The positioning component 130 includes a fixing plate 1320 that is vertically installed on one side of the top of the base plate 110 by a first bolt 1310. Two sleeves 1330 that can be adapted to accommodate the ends of the lower chord steel bars are vertically welded to the top of the inner side of the fixing plate 1320. The top of the two sleeves 1330 is vertically threaded with locking screws 1340. The welding mechanism 200 includes a vertical plate 210 that is vertically fixed to the back of the base plate 110 and a slide 220 that is horizontally mounted on the front of the vertical plate 210. A cylinder 230 is fixedly installed on the slide of the slide 220. A laser welding gun 250 that is suspended directly above the upper chord steel bar is fixedly installed at the output end of the cylinder 230 through a connecting plate 240.

[0039] Based on the above structural configuration, the welding device for processing precast building components consists of a tooling mechanism 100 and a welding mechanism 200. The tooling mechanism 100 is used to assemble and position the upper chord reinforcement and two precast steel reinforcement cages, while the welding mechanism 200 is used to weld the positioned upper chord reinforcement and two steel reinforcement cages. Specifically, during operation, the two precast steel reinforcement cages are first symmetrically arranged and horizontally mounted on the base plate 110 using U-shaped groove blocks 1230. The two U-shaped groove blocks 1230 on the front side and the two U-shaped groove blocks 1230 on the rear side are grouped together to provide structural support for the two steel reinforcement cages. The ends of the lower chord reinforcement in the steel reinforcement cages are clamped in the U-shaped groove blocks 1230. Then, the upper chord reinforcement is placed between two support members 1220. By adjusting the two steel reinforcement cages, the tops of the web reinforcement on the two steel reinforcement cages are brought into contact with the upper chord reinforcement. Finally, the ends of the lower chord reinforcement are fixed using the sleeve 1330 and locking screw 1340 of the positioning component 130. This assembly and positioning of the upper chord steel bar and two steel reinforcement cages within the tooling mechanism 100 is completed. During the welding process, the laser welding gun 250 can move along the slide table 220 to the predetermined welding position with the slide block. The cylinder 230 can drive the laser welding gun 250 to rise and fall. The laser welding gun 250 emits a high-energy laser beam to rapidly heat and melt the contact surface between the upper chord steel bar and the two steel reinforcement cages, forming a strong welded joint. The positioned upper chord steel bar and steel reinforcement cages can be automatically welded according to the preset program. This welding device for prefabricated building components, by setting up the tooling mechanism 100 and with the help of two support members 1220 and the cooperation of the positioning component 130, can achieve high-precision positioning between the upper chord steel bar and the two steel reinforcement cages, effectively reducing the size and shape deviation after welding. At the same time, by using laser welding technology, combined with the automated action driven by the cylinder 230 and the slide table 220, the welding efficiency is significantly improved, the production cycle is shortened, and the needs of high-efficiency industrial production are met.

[0040] Furthermore, the support member 1220 includes a support 1221 and a V-shaped groove block 1222 slidably fitted on its upper part. The inner sides of the V-shaped groove block 1222 and the support 1221 are respectively provided with a first extension edge 1223 and a second extension edge 1224. An adjusting screw 1225 is vertically threaded through the second extension edge 1224. The top end of the adjusting screw 1225 passes through the first extension edge 1223 and is rotatably connected to the first extension edge 1223.

[0041] Furthermore, the support 1221 and the two U-shaped groove blocks 1230 are fixedly connected to the mounting base 1210 by the second bolt 1240. The mounting base 1210 consists of a pad 1211, two T-shaped grooves 1212 that are parallel to each other on the top of the pad 1211 and can accommodate the heads of the second bolts 1240, and two sealing plates 1213 that cover the front and rear sides of the pad 1211 respectively.

[0042] Furthermore, the two sealing plates 1213 are symmetrically distributed and both have an L-shaped structure. Both sealing plates 1213 are fixedly connected to the base plate 110 by the third bolt 1214. The base plate 110 has four strip holes 1110 arranged in a rectangular array and distributed along the length of the base plate 110. The four strip holes 1110 are all adapted to the third bolt 1214.

[0043] Furthermore, both sides of the U-shaped groove 1230 are provided with flared structures 1231.

[0044] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model.
