Description

Technical Field

[0001] The invention relates to the technical field of embedded grooves, and more particularly to a welding tool for embedded grooves. Background Art

[0002] Embedded channel is widely used in high-speed rail, subway, building curtain wall projects. It is a component pre-installed in the concealed project and is a structural accessory placed during the structure pouring. The embedded channel includes the channel body and the I-beam or hanger welded to the back of the channel body. During the embedded operation, the I-beam or hanger is inserted into the concrete.

[0003] Existing embedded channel welding tooling, such as the Chinese patent document with application number CN202321479634.0, locates the welding position of the I-beam through a welding positioning assembly, and then drives the upper clamping assembly to press the I-beam against the channel body, and by flipping the I-beam positioning plate, the movable end of the I-beam positioning plate contacts the back of the channel body. At the same time, the I-beam positioning plate is inserted into the first positioning groove of the channel positioning plate. At this time, the I-beam positioning plate is flipped and positioned at the back of the channel body; since the I-beam positioning plate is provided with the first positioning groove, when the I-beam contacts the back of the channel body, the position of the first positioning groove is convenient for placing the I-beam, and the I-beam position can be positioned by simply inserting the I-beam into the first positioning groove.

[0004] The welding position of the I-beam is positioned by the welding positioning assembly, and the staff needs to place the I-beams on the I-beam positions one by one. The operation is time-consuming and labor-intensive, the work efficiency is low, and the labor intensity is high. It is only applicable to the same size of grooves and I-beams, and the scope of application is small. The different sizes of I-beams can easily cause the position to shift, which can easily cause the welding to be in place, reducing the quality of the finished product. All I-beams need to be placed in place at the same time. The length of the groove is long, which makes the length of the device long, the volume of the device is large, and the area occupied is large.

[0005] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Summary of the invention

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.

[0035] The embodiment of the present application provides a welding tooling for embedded channels. Please refer to Figure 1-Figure 9 : It includes a welding platform 1, two fixed side plates 2 are installed on the welding platform 1, a plurality of conveying rollers 3 are rotatably connected between the two fixed side plates 2, a welding robot 4 is installed on the welding platform 1, a channel conveying mechanism is provided on the welding platform 1, a hanging rod conveying mechanism is provided on the welding platform 1, and an adjustment and positioning mechanism is provided on the welding platform 1;

[0036] The channel conveying mechanism includes a power push rod 5, a C-shaped bracket 6, a fixed support plate 7, a guiding slide bar 8, a rectangular guiding block 9, and a rotating conveying part 10. The power push rod 5 is installed inside the two fixed side plates 2, the C-shaped bracket 6 is installed on the telescopic end of the power push rod 5, the fixed support plate 7 is installed on the back of the C-shaped bracket 6, the guiding slide bar 8 is installed on the fixed support plate 7, the guiding slide bar 8 penetrates through the fixed side plate 2 and is slidably connected to the fixed side plate 2, the rectangular guiding block 9 is installed on the fixed support plate 7, the rectangular guiding block 9 is located on one side of the C-shaped bracket 6, and the rotating conveying part 10 conveys the channel;

[0037] The boom conveying mechanism includes a boom conveying table 11, a fixed guide plate 12, two clamping plates 13, a bearing seat 14, a double-headed threaded screw 15, a rotating knob 16, a boom moving part 17 and a boom positioning part 18. The boom conveying table 11 is installed on the welding platform 1, the fixed guide plate 12 is installed on one side of the surface of the boom conveying table 11, the two clamping plates 13 are slidably connected to the boom conveying table 11, there are notches on the two clamping plates 13, and the notches are completely fitted with the fixed guide plate 12. The bearing seat 14 is installed at the center of one side of the fixed guide plate 12, the double-headed threaded screw 15 is rotatably connected to the bearing seat 14, there are two threaded grooves with opposite spiral directions on the double-headed threaded screw 15, and the two clamping plates 13 are respectively threadedly connected to the two threaded grooves. The rotating knob 16 is installed at one end of the double-headed threaded screw 15. The boom moving part 17 moves the boom, and the boom is positioned and clamped by the boom positioning part 18.

[0038] Specifically, in actual application, the trough is placed with its opening facing upward on the conveying roller 3, and the trough is conveyed by the trough conveying mechanism. The large head of the boom is placed downward on the boom conveying mechanism, and the boom is conveyed by the boom conveying mechanism. The boom and the trough are welded together by the welding robot 4, and the position of the boom is positioned by adjusting the positioning mechanism.

[0039] The two power push rods 5 start to work. The telescopic ends of the power push rods 5 extend in to drive the U-shaped brackets 6 to move. The two U-shaped brackets 6 approach each other, so that the rotating conveying part 10 on the U-shaped brackets 6 is in close contact with the trough. When the U-shaped brackets 6 move, the U-shaped brackets 6 drive the rectangular guide block 9 to move through the fixed support plate 7. The trough is guided by the rectangular guide block 9 so that the trough is located exactly in the middle of the two U-shaped brackets 6. The fixed support plate 7 also drives the guide slide rod 8 to slide along the fixed side plate 2, and the guide slide rod 8 plays a guiding role for the U-shaped brackets 6 to prevent the U-shaped brackets 6 from shifting. The two U-shaped brackets 6 can approach and move away from each other, which is applicable to troughs of different sizes and models, improving the scope of application.

[0040] The large heads of multiple booms are placed downward on the boom conveying table 11. By rotating the rotating knob 16 to rotate the double-headed threaded screw 15, the double-headed threaded screw 15 drives the two clamping plates 13 to move away from and close to each other. The two clamping plates 13 slide along the fixed guide plate 12. The boom moving part 17 drives the boom to move along the two clamping plates 13. There is a gap between the two clamping plates 13 and the boom, which is convenient for the boom to move. It is applicable to booms of different sizes and models, improving the scope of application.

[0041] Refer to the attached instruction Figure 3 、the attached instruction Figure 4 and the attached instruction Figure 5, the rotating conveying part 10 includes a rotating rod 19 rotatably connected to two U-shaped brackets 6. There are three rotating rods 19 on each U-shaped bracket 6. An anti-slip washer 20 is provided on the rotating rod 19. A driving motor 21 is installed on one side of the U-shaped bracket 6. The output end of the driving motor 21 is fixedly connected to the rotating rod 19 on one side. A connecting gear 22 is installed on the top of the rotating rod 19. Multiple connecting gears 22 are connected by a chain 23.

[0042] Specifically, in actual application, the driving motor 21 starts to work. The output end of the driving motor 21 drives the rotating rod 19 on one side to rotate. While the rotating rod 19 is rotating, it drives the connecting gear 22 to rotate. The remaining rotating rods 19 are driven to rotate through the chain 23 and the connecting gear 22. The anti-slip washer 20 on the rotating rod 19 contacts the channel, increasing the friction force. The channel is driven to move on the conveying roller 3 by the rotation of the rotating rod 19, which facilitates the conveying of the channel, reduces the volume of the device, and reduces the floor area of the device.

[0043] Refer to the attached drawings of the specification Figure 6 and the attached drawings of the specification Figure 7 , the boom moving part 17 includes a transverse through groove 24 opened on the boom conveying table 11. An intermittent motor 25 is installed on one side of the bottom of the boom conveying table 11. A connecting bracket 26 is installed on the other side of the bottom of the boom conveying table 11. A threaded lead screw 27 is installed on the output end of the intermittent motor 25. The end of the threaded lead screw 27 away from the intermittent motor 25 is rotatably connected to the connecting bracket 26. A moving slider 28 is threadedly connected to the threaded lead screw 27. The upper part of the moving slider 28 extends into the transverse through groove 24 and is slidably connected to the transverse through groove 24. A moving push plate 29 is installed on the top of the moving slider 28. The bottom of the moving push plate 29 is slidably connected to the boom conveying table 11. A lifting cylinder 30 is installed on the welding platform 1. A lifting positioning plate 31 is installed on the telescopic end of the lifting cylinder 30. The lifting positioning plate 31 is located on one side of the boom conveying table 11. The lowest position of the lifting positioning plate 31 is on the same horizontal plane as the boom conveying table 11.

[0044] Specifically in practical applications, the intermittent motor 25 starts to work, and the output end of the intermittent motor 25 drives the threaded screw 27 to rotate on the connecting bracket 26. The threaded screw 27 rotates to drive the moving slider 28 to slide along the transverse through groove 24, and the moving slider 28 drives the moving push plate 29 to slide on the boom conveying platform 11. The boom is pushed to slide on the boom conveying platform 11 by the moving push plate 29, so that the front end of the boom is moved to the lifting positioning plate 31, and the boom is positioned and clamped by the boom positioning part 18. The lifting cylinder 30 starts to work, and the telescopic end of the lifting cylinder 30 extends in to drive the lifting positioning plate 31 and the boom to rise, so that the top of the boom is tightly fitted with the groove, and the boom is welded together with the groove by the welding robot 4. The intermittent motor 25 is used to make the boom intermittently move to the bottom of the groove, and the boom can be connected and moved for welding in sequence, which improves work efficiency and reduces labor intensity.

[0045] Refer to the drawings, drawings and appendices of the specification Figure 5 The boom positioning portion 18 includes two clamping cylinders 32 installed on a lifting positioning plate 31, a fixing block 33 is installed on the telescopic end of the clamping cylinder 32, a triangular clamping plate 34 is installed on the fixing block 33, the openings of the two triangular clamping plates 34 are opposite, and an anti-slip pad 35 is installed on the inner wall of the triangular clamping plate 34.

[0046] Specifically in practical applications, after the boom is transported to the lifting and positioning plate 31, it is not at the center of the lifting and positioning plate 31. The two clamping cylinders 32 start to work, and the telescopic ends of the two clamping cylinders 32 extend to drive the triangular clamping plate 34 to move. The two triangular clamping plates 34 are close to each other, and one side of the triangular clamping plate 34 first contacts the boom, so that the boom can be moved to the center of the lifting and positioning plate 31. When the two sides of the triangular clamping plate 34 contact the boom, the boom is located at the center of the lifting and positioning plate 31. The anti-skid pad 35 on the triangular clamping plate 34 plays an anti-skid role, which facilitates the positioning and clamping of the boom, avoids the boom from bending and tilting, improves the welding quality, and improves the quality of the finished product.

[0047] The triangular clamping plate 34 can be replaced with a flat clamping plate to clamp and fix the I-beam.

[0048] Refer to the instruction manual Figure 2 , Instruction Manual Figure 3 And the instruction manual Fig. 9, the adjustment and positioning mechanism includes a transverse chute 36 opened on one side fixed side plate 2. A sliding side plate 37 is slidably connected in the transverse chute 36. A plurality of rotating balls 38 are provided at the upper and lower ends of the transverse chute 36. The upper and lower ends of the sliding side plate 37 are in contact with the rotating balls 38. A locking screw 39 is threadedly connected to the fixed side plate 2. The locking screw 39 penetrates into the transverse chute 36 and is in contact with the sliding side plate 37. A fixed seat 40 is installed on the side of the sliding side plate 37 away from the fixed side plate 2. A contact displacement sensor 41 is installed on the fixed seat 40.

[0049] Specifically, in actual application, according to the distance between adjacent suspension rods, the position of the contact displacement sensor 41 is adjusted. The sliding side plate 37 slides in the transverse chute 36. The upper and lower ends of the sliding side plate 37 are in contact with the rotating balls 38. The rotating balls 38 facilitate the sliding of the sliding side plate 37. The sliding side plate 37 drives the contact displacement sensor 41 to move through the fixed seat 40. After the contact displacement sensor 41 moves into place, the locking screw 39 is tightened. The locking screw 39 contacts the sliding side plate 37 to fix the sliding side plate 37. After the suspension rod and the channel are welded together, the channel moves towards the contact displacement sensor 41. When the contact displacement sensor 41 detects the suspension rod, the movement of the channel stops. The next suspension rod and the channel are welded together. The positioning of the suspension rod is accurate, and the distance between adjacent suspension rods is the same, avoiding the situation where the suspension rod is not welded in place and improving the product quality.

[0050] Refer to the attached drawings of the specification Figure 1 and the attached drawings of the specification Figure 2 , a carrying roller 42 is provided on one side of the U-shaped bracket 6. The carrying roller 42 is rotatably connected between the two fixed side plates 2. A fixed connecting plate 43 is installed between the two fixed side plates 2. A pressing cylinder 44 is installed at the bottom of the fixed connecting plate 43. A pressing bracket 45 is installed on the telescopic end of the pressing cylinder 44. A pressing roller 46 is rotatably connected to the pressing bracket 45. Two connecting rollers 47 are rotatably connected to the two fixed side plates 2. There is a distance between the two connecting rollers 47. The pressing bracket 45 is located between the carrying roller 42 and the connecting roller 47.

[0051] Specifically, in actual application, the channel is conveyed onto the carrying roller 42 and the two connecting rollers 47. The pressing cylinder 44 starts to work. The telescopic end of the pressing cylinder 44 extends and drives the pressing bracket 45 to descend. The pressing roller 46 on the pressing bracket 45 contacts the channel, preventing the channel from moving up when the suspension rod contacts the channel, avoiding the phenomenon of channel displacement, and avoiding insecure welding. The welded suspension rod can be removed from between the two connecting rollers 47.
