Description

Technical Field

[0001] The present invention relates to the technical field of welding processing, and particularly relates to a positioning welding device for building metal embedded parts. Background Art

[0002] Building metal embedded parts are metal components pre-embedded in concrete structures during construction projects; the most common and main function of embedded parts is to serve as connection points for connecting steel structures, mechanical equipment, or other structural components to concrete structures. Embedded parts mainly consist of bent anchor bars and anchor plates, that is, four bent anchor bars that are bent to increase the uplift resistance of the embedded parts and prevent them from being pulled out of the concrete are evenly welded in a rectangular distribution on an anchor plate.

[0003] In the existing method of welding bent anchor bars to the anchor plate, workers measure and mark the center positions of the four anchor bars on the anchor plate manually, then fix the anchor plate through a fixture, and then place the anchor bars to the corresponding marked positions in sequence and perform welding processing.

[0004] However, the current embedded parts have the following problems during the welding process: In the existing welding method, the alignment and welding of each anchor bar are carried out independently, which means that the anchor bars need to be repositioned and fixed before each welding, thus increasing the time and labor costs of the entire welding process. Moreover, the individual alignment of each anchor bar will accumulate errors, resulting in inconsistent welding quality. Summary of the Invention

Detailed implementation manners

[0032] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0033] As Figure 1 shown, a positioning and welding device for building metal embedded parts includes a bottom plate 10; a fixing frame 11 is installed at the upper end of the bottom plate 10, the fixing frame 11 is in an inverted U-shaped structure, and a rectangular frame 12 for limiting the anchor plate is fixedly installed at the upper end of the bottom plate 10 below the horizontal section of the fixing frame 11, and a positioning mechanism 2 is arranged on the fixing frame 11.

[0034] As Figure 1 and Figure 2 shown, the positioning mechanism 2 includes a rectangular groove. Rectangular grooves are opened on both vertical sections of the fixing frame 11. Fixing blocks 20 are slidably installed in the rectangular grooves. A first compression spring 21 is installed between the upper end of each fixing block 20 and the inner wall of the corresponding rectangular groove. A supporting plate 22 located directly above the rectangular frame 12 is fixedly installed between the two fixing blocks 20, and two symmetrically arranged support plates 23 are slidably installed at the lower end of the supporting plate 22.

[0035] As Figure 1 and Figure 2As shown, a pressing part 28 for pressing down and aligning the anchor bars is provided on the supporting plate 22. Pre-fixing parts 24 for pre-positioning the corresponding anchor bars are provided on both of the two supporting plates 23. A fixing part 25 for pushing and fixing the anchor bars and a driving part 27 for driving the pressing part 28 and the two supporting plates 23 to move are further provided on the supporting plate 22. A welding part 26 for welding the anchor bars and the anchor plate is provided on the fixing part 25.

[0036] During specific operation, an operator places the anchor plate into the rectangular frame 12. The inner contour of the rectangular frame 12 is the same as the outer contour of the anchor plate, so that the anchor plate can be limited. The driving part 27 then pushes the pressing part 28, the pre-fixing part 24, the fixing part 25 and the welding part 26 to move downward. With the pushing of the driving part 27 on the above components and under the action of the first compression spring 21, the supporting plate 22 is driven by the fixing block 20 to move downward until the fixing plate 281 abuts against the lower end of the rectangular groove. After that, with the pushing of the driving part 27, the two supporting plates 23 are pushed away from each other to move to the corresponding positions. Then the operator places the anchor bars at the positions of the pre-fixing parts 24. Then the fixing part 25 moves close to the anchor bars to squeeze and fix the anchor bars. Then the pressing part 28 presses the anchor bars from top to bottom to make the anchor bars closely adhere to the anchor plate. Then the welding part 26 welds the connection part of the anchor bars and the anchor plate.

[0037] As Figure 2 and Figure 3 shown, the pre-fixing part 24 includes a supporting component. Two groups of symmetrically arranged front and rear supporting components are installed on the opposite sides of the two supporting plates 23. Each group of supporting components consists of two symmetrically arranged upper and lower supports 240. The support 240 has a U-shaped structure. Two symmetrically arranged and coaxial limiting rings 241 are hinged between the two horizontal sections of the support 240. Support plates are installed on the opposite sides of the two limiting rings 241 on the same support 240. A return spring 242 is installed between the support plate and the corresponding support 240.

[0038] As Figure 1 、 Figure 2 and Figure 4 shown, the fixing part 25 includes a positioning plate 250. Two symmetrically arranged left and right positioning plates 250 are slidably installed at the lower end of the supporting plate 22. The two supporting plates 23 are located between the two positioning plates 250. A connecting plate 251 is installed at the lower end of the positioning plate 250. Two pushing blocks 252 are symmetrically installed on the opposite surfaces of the two connecting plates 251 in the front and rear directions. A second V-shaped groove is formed on the side of the pushing block 252 close to the corresponding supporting plate 23. A pushing component for driving the pushing block 252 to move is provided on the supporting plate 22.

[0039] As Figure 4As shown, the pushing component includes a bidirectional screw rod 253. The upper end of the supporting plate 22 is rotatably installed with a bidirectional screw rod 253 through a bearing seat. Each of the two threaded sections of the bidirectional screw rod 253 is threadedly connected with a screw plate 254. The supporting plate 22 is provided with sliding grooves corresponding to the screw plates 254 one by one. After the screw plate 254 slides through the corresponding sliding groove, it is fixedly connected with the corresponding positioning plate 250.

[0040] During specific operation, after the driving part 27 pushes the two supporting plates 23 to corresponding positions, an operator pushes the anchor bar into the corresponding supporting component, that is, pushes the limiting ring 241 from the notch position between the two limiting rings 241 on the corresponding support 240, so that the two limiting rings 241 on the same support 240 move away from each other and compress the return spring 242 at the same time. At this time, with the pushing of the operator, the anchor bar will move to the middle position between the two limiting rings 241 on the same support 240. At the same time, the limiting ring 241 rotates and resets under the action of the return spring 242, so that the two limiting rings 241 on the same support 240 are combined into a C-shaped structure to pre-limit the corresponding anchor bar.

[0041] The external motor installed on the supporting plate 22 operates to drive the bidirectional screw rod 253 to rotate. The bidirectional screw rod 253 drives the corresponding two positioning plates 250 to approach each other through the two screw plates 254. The positioning plate 250 drives the corresponding pushing block 252 to move towards the corresponding anchor bar through the connecting plate 251 until the pushing block 252 abuts against the anchor bar and pushes the anchor bar to closely adhere to the inner wall of the corresponding limiting ring 241 to complete the limiting of the anchor bar. Then, the pressing part 28 presses the anchor bar downward, so that the anchor bar is limited and straightened, and the anchor bar is closely adhered to the anchor plate to ensure the welding quality of the subsequent welding part 26 for the anchor bar and the anchor plate.

[0042] As Figure 1 、 Figure 2 and Figure 5 shown, the pressing part 28 includes a second compression spring 280. The upper end of the supporting plate 22 is installed with a fixing plate 281 through the second compression spring 280. The lower end of the fixing plate 281 is fixedly installed with four support columns 282 distributed in a rectangle. The lower end of the support column 282 is installed with a pressing plate 283, and the lower end of the pressing plate 283 is provided with a first V-shaped groove.

[0043] As Figure 1 、 Figure 2 and Figure 5As shown, the driving part 27 includes a cylinder 270, and the upper end of the fixed frame 11 is equipped with the cylinder 270, and the telescopic end of the cylinder 270 passes through the fixed plate 281 and is equipped with a push plate 271, and the lower end of the push plate 271 is symmetrically equipped with two shaft rods 272, and the lower ends of the two shaft rods 272 slide through the fixed plate 281 and the supporting plate 22 and are jointly equipped with a driving block 273, and the driving block 273 is provided with a pushing and pulling member 4 for pushing and pulling the two support plates 23, and the lower end of the driving block 273 is provided with a pressing member 5 for pressing the anchor plate.

[0044] like Figure 2 and Figure 4 As shown, the push-pull member 4 includes a push-pull plate 40, and two push-pull plates 40 that are symmetrical front and back and located on the front and back sides of the driving block 273 are installed on the opposite surfaces of the two support plates 23. A roller shaft 41 is installed between the two front and rear opposite push-pull plates 40, and guide grooves 42 are opened at positions on the driving block 273 corresponding to the roller shafts 41. The upper part of the guide groove 42 is a vertical section, and the lower part is an inclined section. The roller shaft 41 slides through the corresponding guide groove 42.

[0045] like Figure 1 and Figure 2 As shown, the pressing member 5 includes a No. 3 compression spring 50, and the lower end of the driving block 273 is installed with a pressing plate 51 through the No. 3 compression spring 50. The four corners of the upper end of the pressing plate 51 are fixedly installed with guide columns, and the guide columns are also slidably connected to the driving block 273.

[0046] During specific operation, the cylinder 270 pushes the push plate 271 to move downward, and the push plate 271 pushes the driving block 273 to move downward through the shaft 272. In the initial state, the driving block 273 pulls and resists the supporting plate 22. At this time, as the driving block 273 moves downward, the supporting plate 22 will maintain a fit with the supporting plate 22 under the action of the No. 1 compression spring 21 and move downward synchronously until the fixed block 20 contacts the lower end of the rectangular groove to limit the further downward movement of the supporting plate 22. After that, as the driving block 273 is pushed to continue to move downward, the supporting plate 22 cannot continue to move downward, and the driving block 273 at this time will gradually move away from the supporting plate 22. The support plate 22 and the driving block 273 are guided by the roller shaft 41 through the inclined section of the guide groove 42, so that the push-pull plate 40 pushes the corresponding support plate 23 away from the driving block 273 to the corresponding position. When the support plate 23 moves into place, the roller shaft 41 moves to the connection between the vertical section and the inclined section of the guide groove 42. At this time, the anchor bar is manually placed at the corresponding position of the pre-fixed part 24. After the placement is completed, the anchor bar is squeezed and fixed by the fixing part 25. In addition, during the downward movement of the driving block 273, the No. 3 compression spring 50 will push the resistance plate 51 to contact and squeeze the anchor plate, so as to further improve the stability of the anchor plate.

[0047] Then, as the driving block 273 continues to move downward, the roller shaft 41 will move to the vertical section of the guiding groove 42, enabling the driving block 273 to continue moving downward while maintaining the pushing of the supporting plate 23 through the pushing and pulling plate 40. The continuous downward movement of the driving block 273 will cause the pushing and pressing plate 271 to abut against the upper end of the fixing plate 281, so as to push and squeeze the fixing plate 281 to move downward, and at the same time compress the second compression spring 280. The downward movement of the fixing plate 281 will push the corresponding pressing plate 283 to squeeze the corresponding anchor bar through the support column 282, so as to ensure the fitting of the anchor bar and the anchor plate. At the same time, under the action of the inner wall of the first V-shaped groove, the anchor bar will be pushed and adjusted in position to be straightened.

[0048] After the anchor bar is straightened and fixed, the welding part 26 will carry out welding processing on it. After the welding processing is completed, the external motor drives the bidirectional screw 253 to rotate in the reverse direction, so that the pushing block 252 releases the extrusion and fixation of the anchor bar and moves away from the anchor bar. Then, the air cylinder 270 pulls the pushing and pressing plate 271 to move upward. The pushing and pressing plate 271 will pull the driving block 273 to move upward through the shaft rod 272. At this time, the fixing plate 281 remains in contact with the pushing and pressing plate 271 and moves upward under the action of the second compression spring 280, so that the pressing plate 283 moves away from the anchor bar until the second compression spring 280 is reset. Then, the roller shaft 41 moves to the connection of the vertical section and the inclined section of the guiding groove 42. With the pulling of the air cylinder 270, the pushing and pulling plate 40 will move away from the fixing plate 281, and the driving block 273 moves upward synchronously, so that the roller shaft 41 slides in the inclined section of the guiding groove 42 to guide the supporting plate 23 to move and reset in the direction close to the driving block 273. During the movement of the supporting plate 23, the corresponding two limiting rings 241 will abut against the corresponding anchor bar and rotate away from each other, so that the anchor bar disengages from the corresponding two limiting rings 241. Then, the reset spring 242 is reset. At the same time, the upper end of the driving block 273 abuts against the supporting plate 22. With the upward movement of the driving block 273, it will pull the pressing plate 51 to move upward away from the anchor plate, so as to push the supporting plate 22 to move upward and compress the first compression spring 21, so that the supporting plate 22 is higher than the anchor bar. At this time, the welded embedded part can be taken out.

[0049] As Figure 5 、 Figure 6 and Figure 7 shown, the welding part 26 includes an L-shaped plate 260. The opposite surfaces of the two connecting plates 251 are fixedly installed with L-shaped plates 260 corresponding to the supporting components one by one. One end of the horizontal section of the L-shaped plate 260 close to the middle of the bottom plate 10 is fixedly installed with a C-shaped plate 261. An arc-shaped groove 262 having the same contour as the C-shaped plate 261 is opened at the lower end of the C-shaped plate 261. Two sliders are symmetrically slidably installed in the front and back in the arc-shaped groove 262. Welding assemblies 263 are installed at the lower ends of the two sliders. An actuator 3 for driving the corresponding welding assembly 263 to move is arranged on the C-shaped plate 261.

[0050] As Figure 5 、 Figure 6 andFigure 7 As shown, the actuator 3 includes a movable groove. An activity groove communicating with the arc groove 262 is formed in the C-shaped plate 261. A C-shaped gear ring 30 coaxial with the C-shaped plate 261 is rotatably installed in the activity groove. A stepping motor 31 is installed at the upper end of the C-shaped plate 261 through a motor base. The output shaft of the stepping motor 31 rotatably penetrates through the motor base and is then installed with a spur gear 32. A notch 33 is formed in the C-shaped plate 261 at a position corresponding to the corresponding spur gear 32. The notch 33 communicates with the activity groove. The spur gear 32 meshes with the corresponding C-shaped gear ring 30 through the notch 33.

[0051] During specific operation, when an external motor drives the connecting plate 251 to move towards the anchor bar through the bidirectional screw 253, the connecting plate 251 will drive the C-shaped plate 261 to move towards the anchor bar through the L-shaped plate 260, so that the anchor bar is located in the middle of the C-shaped plate 261. After the anchor bar is aligned and fixed, the stepping motor 31 drives the C-shaped gear ring 30 to rotate 180 degrees through the spur gear 32, and the C-shaped gear ring 30 drives the corresponding two welding assemblies 263 to rotate synchronously to perform welding processing on the connection between the corresponding anchor bar and the anchor plate. After welding is completed, the fixing part 25, the pre-fixing part 24, and the pressing part 28 release the limit fixation on the anchor bar and drive the supporting plate 22 and the welding part 26 to move away from the anchor bar together. At this time, the embedded part can be taken out, and then the above operation is repeated to continue the welding processing operation of the embedded part.
