Scaffolding buckle welding device

Abstract

The present invention belongs to the field of welding technology, and specifically provides a scaffolding buckle welding device, including a feeding assembly, a supporting assembly, a material support assembly, a hoop assembly, a positioning assembly and a welding assembly. The buckle to be welded is supported by the material support assembly. Multiple material support assemblies can be set as needed. Multiple material support assemblies are centrally arranged on a machine base, and the position is more centralized. When manually placing the buckle and the positioning ring, workers do not need to move around, which reduces the labor intensity. When working, firstly, the positioning assembly is used to stop and limit one side of the buckle, and then the hoop assembly is used to tighten the positioning ring and the steel pipe into one, so that the positioning ring stops and limits the buckle from the other side. The two work together to ensure that the buckle is firmly clamped during welding, ensuring the welding quality. In addition, the setting position of the welding assembly is far away from the material support assembly, and the welding slag will not splash onto the material support block, and will not affect the placement of the buckle and the positioning ring, which also helps to ensure the smooth progress of the welding work.

Description

Technical Field

[0001] The invention belongs to the technical field of welding, and in particular relates to a scaffolding buckle welding device. Background Art

[0002] The disc-type scaffolding is a common scaffolding structure, which consists of vertical poles, horizontal poles, diagonal poles and latches. Among them, the vertical poles are the most important and core structural parts of the disc-type scaffolding. The vertical poles are composed of round steel pipes and multiple disc-shaped discs distributed on the steel pipes at intervals. The discs are also called connecting discs. When producing the vertical poles, the discs and steel pipes need to be welded together. In addition, according to the requirements of relevant industry standards (such as "JG / T 503-2016-Socket-type disc-type steel pipe support components"), the connection between the disc and the steel pipe should be double-sided welded and fully welded.

[0003] In the prior art, there are related semi-automatic or automatic welding equipment for welding between steel pipes and buckles. It is only necessary to put multiple buckles into the corresponding tooling molds in turn, and after the vertical pole is passed through the multiple buckles by the automatic pipe threading machine, automatic welding is achieved by the welding machine. The shortcomings of this working method are: 1. It is necessary to rely on manual labor to place the buckle material into the corresponding tooling fixture. The spacing between the tooling fixtures is consistent with the spacing of the buckles on the vertical pole. Since the length of the vertical pole is generally 2-5m, when placing the buckle material, the worker needs to walk along the equipment to place the buckle material into multiple tooling molds respectively. 2. During welding, the buckle is always in the tooling mold. The welding slag generated during welding is easy to splash into the limit groove of the tooling mold. The welding slag adheres to the inner wall of the limit groove, which will cause the buckle to be stuck in the placement and position deviation after placement. It will have an adverse effect on the smooth progress of the welding work and the welding position accuracy of the buckle. Summary of the invention

[0029] The scaffolding buckle welding device provided by the present invention comprises a feeding assembly, a supporting assembly, a hoop assembly, a positioning assembly and a welding assembly. The feeding assembly can convey the steel pipe along the axial direction of the steel pipe. The supporting assembly is used to support the buckle and the positioning ring to be welded, so that the steel pipe can pass through the positioning ring and the buckle during conveying. The positioning assembly is used to stop the buckle before the buckle and the steel pipe are welded to prevent the buckle from moving forward together with the conveyed steel pipe. When the positioning ring moves to the position of the hoop assembly, the hoop assembly can clamp the positioning ring on the steel pipe. The clamped positioning ring forms a bulge on the outer wall of the steel pipe, which can stop and limit the buckle. When the positioning ring moves with the steel pipe to overlap with the buckle, the welding assembly welds the buckle, the positioning ring and the steel pipe into one. Since the positioning ring is small in size, it can be accommodated in the weld between the buckle and the steel pipe and welded to the steel pipe together with the buckle.

[0030] The scaffolding buckle welding device provided by the present invention supports the buckle to be welded by a supporting assembly. A plurality of supporting assemblies can be provided as needed. The plurality of supporting assemblies are centrally arranged on the machine base, and the positions are more centralized. When the buckle and the positioning ring are placed manually, the workers do not need to move around, and the labor intensity is reduced. During work, the positioning assembly is first used to stop and limit one side of the buckle, and then the positioning ring and the steel pipe are clamped together by the hoop assembly, so that the positioning ring stops and limits the buckle from the other side. The two work together to ensure that the buckle is firmly clamped during welding, and the welding quality is ensured. In addition, the setting position of the welding assembly is far away from the supporting assembly, and the welding slag will not splash onto the supporting block, and will not affect the placement of the buckle and the positioning ring, which also helps to ensure the smooth progress of the welding work.

The feeding assembly 10 is used to convey the steel pipe 70 along a preset direction; the supporting assembly 20 is arranged on the unloading side of the feeding assembly 10, and the supporting assembly 20 includes a machine base 21 and a track 22 arranged in sequence along the conveying direction of the steel pipe 70, and the track 22 extends along the conveying direction of the steel pipe 70. A moving vehicle 23 is movably provided on the track 22, and a clamping mechanism 231 is provided on the moving vehicle 23. The clamping mechanism 231 can clamp one end of the steel pipe 70 and drive the steel pipe 70 to rotate around its own axis; the supporting assembly 30 includes a supporting block 31 and a first lifting rod 32. The upper surface of the supporting block 31 is provided with a first receiving groove 311 and a second receiving groove 312 in sequence along the conveying direction of the steel pipe 70. The first receiving groove 311 and the second receiving groove 312 are both semicircular grooves. The first receiving groove 311 is used to accommodate the positioning ring 80, and the second receiving groove 312 is used to accommodate the buckle 90. The first lifting rod 32 is used to drive the supporting block 31 to lift vertically. When the supporting block 31 is at the upper dead center position, The positioning ring 80, the buckle 90 and the steel pipe 70 are on the same axis. When the support block 31 is at the lower dead center position, the support block 31 is accommodated in the inner cavity of the machine base 21; the hoop assembly 40 is arranged on the machine base 21 and is located on the side of the support assembly 30 away from the feeding assembly 10. The hoop assembly 40 is used to apply an extrusion force to the positioning ring 80, and the extrusion force is toward the center of the steel pipe 70, so that the positioning ring 80 can be clamped onto the steel pipe 70; the positioning assembly 50 is arranged on the machine base 21 and is located at the hoop assembly Part 40 is on the side away from the support assembly 30, and the positioning assembly 50 has a stop state and a release state.

When the disc buckle 90 and the steel pipe 70 are welded into one, the positioning assembly 50 switches to the release state.

[0050] Compared with the prior art, the advantageous effects of the disc buckle scaffold welding device provided by the embodiment of the present invention are:

[0051] The scaffolding buckle welding device provided by the embodiment of the present invention includes a feeding assembly 10, a supporting assembly 20, a supporting assembly 30, a hoop assembly 40, a positioning assembly 50 and a welding assembly 60. The feeding assembly 10 can transport the steel pipe 70 along the axial direction of the steel pipe 70. The supporting assembly 30 is used to support the buckle 90 and the positioning ring 80 to be welded, so that the steel pipe 70 can pass through the positioning ring 80 and the buckle 90 during transportation. The positioning assembly 50 is used to stop the buckle 90 before the buckle 90 and the steel pipe 70 are welded to prevent the buckle 90 from moving forward with the transported steel pipe 70. When the positioning ring 80 moves to the position of the hoop assembly 40, the hoop assembly 40 can clamp the positioning ring 80 on the steel pipe 70. The clamped positioning ring 80 forms a bulge on the outer wall of the steel pipe 70, which can stop and limit the buckle 90. When the positioning ring 80 moves with the steel pipe 70 to overlap with the disc buckle 90, the welding assembly 60 welds the disc buckle 90, the positioning ring 80 and the steel pipe 70 into one. Since the positioning ring 80 is relatively small in size, it can be accommodated in the weld between the disc buckle 90 and the steel pipe 70 and is welded to the steel pipe 70 together with the disc buckle 90.

[0052] The scaffolding buckle welding device provided by the embodiment of the present invention supports the buckle 90 to be welded through the support assembly 30. Multiple support assemblies 30 can be set as needed. Multiple support assemblies 30 are centrally arranged on the machine base 21, and the position is more concentrated. When the buckle 90 and the positioning ring 80 are placed manually, the workers do not need to move around, which reduces the labor intensity. When working, firstly, the positioning assembly 50 is used to stop and limit one side of the buckle 90, and then the hoop assembly 40 is used to tighten the positioning ring 80 and the steel pipe 70 as a whole, so that the positioning ring 80 stops and limits the buckle 90 from the other side. The two work together to ensure that the buckle 90 is firmly clamped during welding, ensuring the welding quality. In addition, the setting position of the welding assembly 60 is far away from the support assembly 30, and the welding slag will not splash onto the support block 31, and will not affect the placement of the buckle 90 and the positioning ring 80, which also helps to ensure the smooth progress of the welding work.

[0053] In order to facilitate the understanding of the present invention, the specific working method of the scaffolding buckle welding device provided by the present invention is described below, which mainly includes the following steps:

[0054] (1) Raw material preparation: specific, such as Figure 1 and Figure 2 As shown, the steel pipe 70, the positioning ring 80 and the disc buckle 90 are obtained by cutting. The surface of the steel pipe 70 should be smooth without defects such as rust, pits, and protrusions. The material of the steel pipe 70, the positioning ring 80 and the disc buckle 90 can adopt the common material of the disc buckle 90 type scaffolding.

[0055] (2) Material placement and transportation: Specifically, Figure 3As shown, the steel pipe 70 is placed on the loading assembly 10, the steel pipe 70 is placed horizontally, and the steel pipe 70 is transported along its own central axis direction. The positioning ring 80 and the buckle 90 are placed on the support block 31, and the support block 31 is in an ascending state. The steel pipe 70, the positioning ring 80 and the buckle 90 are coaxially aligned. Figure 4 As shown, the feeding assembly 10 drives the steel pipe 70 to be transported forward, and one end of the steel pipe 70 passes through the positioning ring 80, the buckle 90, and the hoop assembly 40 in sequence, and is then firmly clamped by the clamping assembly of the mobile vehicle 23.

[0056] (3) Release the positioning ring 80 and the buckle 90 on the first support block 31: Specifically, Figure 4 As shown, first, the first supporting block 31 descends, and the other supporting blocks 31 remain stationary, and the positioning ring 80 and the disc buckle 90 supported by the first supporting block 31 remain on the steel pipe 70; then the steel pipe 70 continues to move forward, driving the positioning ring 80 and the disc buckle 90 supported by the first supporting block 31 to move along with the steel pipe 70, and transporting the first disc buckle 90 to the positioning assembly 50, and at the same time transporting the first positioning ring 80 to the working position of the hoop assembly 40.

[0057] (4) Tighten the positioning ring 80 and the steel pipe 70 together: Specifically, Figure 5-Figure 7 As shown, when the positioning ring 80 moves to the working position of the hoop assembly 40, the hoop assembly 40 contracts to tighten the positioning ring 80 onto the steel pipe 70.

[0058] (5) Conveying the positioning ring 80 to abut against the disc buckle 90: Specifically, while the disc buckle 90 is limited by the positioning assembly 50, the steel pipe 70 drives the tightened positioning ring 80 to move forward along with the moving vehicle 23, and the positioning assembly 50 blocks the disc buckle 90 from moving forward along with the steel pipe 70 until the positioning ring 80 and the disc buckle 90 abut against each other. The pushing force applied by the positioning ring 80 to the disc buckle 90 is transmitted to the positioning assembly 50. When the positioning assembly 50 detects that the thrust has reached a certain value, it indicates that the positioning ring 80 and the disc buckle 90 are abutting against each other.

[0059] (6) Welding the first plate buckle 90 and the steel pipe 70 into one body: Specifically, Figure 8 As shown, the welding assembly 60 is lowered to the welding position to weld the two welds formed by the buckle 90 and the steel pipe 70. During the welding, the clamping assembly of the mobile vehicle 23 drives the steel pipe 70 to rotate at a constant speed to achieve full welding of the entire weld. Since the volume and diameter of the positioning ring 80 are small, it will be welded into the weld together.

[0060] (7) Repeat steps (3) to (6) to sequentially convey, position and weld the second, third and fourth disc buckles 90, and finally complete the welding of the scaffolding disc buckles.

[0061] In the embodiment of the present invention, the feeding assembly 10 is used to convey the steel pipe 70. The feeding assembly 10 can specifically adopt the pipe conveying equipment in the prior art, such as a roller conveyor, a feeding push rod, etc.

[0062] The support assembly 20 includes a base 21 and a track 22, wherein the base 21 is used to provide support for various components installed thereon, and the track 22 is used to support the mobile vehicle 23 and allow the mobile vehicle 23 to move. The mobile vehicle 23 has a clamping mechanism 231, which can be a clamp such as a three-jaw chuck that can clamp and fix the steel pipe 70, and can drive the steel pipe 70 to rotate, so that the welding assembly 60 can weld the entire circular weld.

[0063] The moving vehicle 23 can be driven by a built-in motor and can move at a constant speed along the track 22 to slowly pull the steel pipe 70 from the loading assembly 10 to one side of the track 22. During the pulling of the steel pipe 70, the buckles 90 and positioning rings 80 carried by the multiple supporting assemblies 30 are released in sequence and welded to the steel pipe 70.

[0064] The support assembly 30 includes a support block 31 and a first lifting rod 32. The support block 31 is a metal block, and its top surface is provided with a first receiving groove 311 and a second receiving groove 312 that are adapted to the shape and size of the positioning ring 80 and the buckle 90. Before welding, the worker needs to place multiple buckles 90 and multiple positioning rings 80 as shown in the following figure. Figure 3 The method shown is to manually place it on the supporting block 31.

[0065] The first lifting rod 32 can be a hydraulic lifting rod, an electric lifting rod, a pneumatic lifting rod, etc. After the first lifting rod 32 drives the supporting block 31 to descend, the limit stops of the positioning ring 80 and the buckle 90 are contacted, and the positioning ring 80 can move forward together with the steel pipe 70 until the buckle 90 reaches the limit position of the positioning assembly 50 and the positioning ring 80 reaches the working position of the hoop assembly 40.

[0066] The hoop assembly 40 can be a tube shrinking machine in the prior art, which can be directly purchased on the market, and its specific structure and working principle are not described in detail. The hoop assembly 40 can apply extrusion force to the entire circumferential direction of the positioning ring 80 to tighten the positioning ring 80 on the steel pipe 70. It should be noted that the tightening position of the positioning ring 80 is the welding position of the buckle 90. In order to ensure that the distance between the tightening position of the positioning ring 80 and the steel pipe 70 is accurate, the distance between the steel pipe 70 and the machine base 21 can be detected in real time by instruments such as a distance sensor 232.

[0067] The positioning component 50 is used to stop and limit the disc buckle 90. The positioning component 50 can adopt a structure such as a limit rod with a telescopic function, which can stop and limit the disc buckle 90 and can also retract to release the disc buckle 90.

[0068] The welding assembly 60 is used to weld the weld between the plate buckle 90 and the steel pipe 70. Figure 6 and Figure 8 In some possible embodiments, the welding assembly 60 includes two welding heads 61 arranged opposite to each other. The two welding heads 61 are respectively used to weld two welds formed between the buckle 90 and the steel pipe 70. The welding heads 61 can specifically be laser welding heads 61.

[0069] See also Figure 2 and Figure 7 In some possible embodiments, the inner hole edge of the buckle 90 is provided with a chamfer 91 for accommodating the positioning ring 80. The positioning ring 80 is accommodated in the chamfer 91 and can be welded into the weld without affecting the appearance of the buckle 90.

[0070] See also Figure 3 and Fig. 9 In some possible embodiments, a distance sensor 232 is provided on the mobile vehicle 23 , and the distance sensor 232 is used to detect the relative distance between the mobile vehicle 23 and the base 21 .

[0071] In this embodiment, the distance sensor 232 can directly use the existing distance detection element on the market, which can detect the relative distance between the moving vehicle 23 and the base 21 in real time. Since the moving vehicle 23 clamps the steel pipe 70, the conveying length of the steel pipe 70 can be calculated. When the steel pipe 70 is conveyed to a certain length, the distance sensor 232 feeds back the result to the controller, and the controller controls the action of the hoop assembly 40 to tighten the positioning ring 80 on the steel pipe 70. Such a setting can ensure that the relative position of the buckle 90 and the steel pipe 70 is accurate.

[0072] See also Figure 3 and Figure 4 In some possible embodiments, the feeding assembly 10 includes a support frame 11 and a conveying roller 12. The support frame 11 is arranged on the side of the machine base 21 away from the track 22; a plurality of conveying rollers 12 are arranged on the support frame 11 at intervals along the conveying direction of the steel pipe 70, and the conveying rollers 12 are used to support the steel pipe 70. The conveying rollers 12 can be driven by a motor, and the plurality of conveying rollers 12 rotate synchronously, which can drive the steel pipe 70 to be conveyed forward.

[0073] See also Figure 4 , Figure 6 , Figure 8 , Fig. 9 and Fig.10 In some possible embodiments, a plurality of supporting assemblies 30 are provided, and the plurality of supporting assemblies 30 are arranged in sequence along the conveying direction of the steel pipe 70. During operation, the first lifting rods 32 of the plurality of supporting assemblies 30 descend in sequence in the direction opposite to the conveying direction of the steel pipe 70.

[0074] When the support block 31 is still in the ascending state, the positioning ring 80 and the buckle 90 are limited on the support block 31 and will not move forward with the steel pipe 70. When the support block 31 descends, the first receiving groove 311 and the second receiving groove 312 release the positioning ring 80 and the buckle 90, and the positioning ring 80 and the buckle 90 can move forward with the steel pipe 70.

[0075] See also Figure 5 and Figure 7 In some possible embodiments, the hoop assembly 40 includes a plurality of telescopic rods 41 and a plurality of pressing heads 42. The plurality of telescopic rods 41 are arranged at intervals on the machine base 21 along the circumferential direction of the steel pipe 70; and the plurality of pressing heads 42 are arranged one by one at one end of the telescopic rods 41 facing the steel pipe 70.

[0076] In this embodiment, the telescopic rod 41 can be driven by electric, pneumatic, hydraulic or other means, and multiple telescopic rods 41 are synchronously extended and retracted. When the telescopic rod 41 is extended, the positioning ring 80 can be squeezed to tighten the positioning ring 80 onto the steel pipe 70. When the telescopic rod 41 is retracted, the telescopic rod 41 will not interfere with the forward movement of the steel pipe 70 and the buckle 90.

[0077] See also Figure 5 In some possible embodiments, a clamping groove is provided on one side of the top pressure head 42 facing the material incoming direction of the positioning ring 80. When the telescopic rod 41 is in an extended state, the positioning ring 80 is confined in the clamping groove, which can prevent the positioning ring 80 from moving forward together with the steel pipe 70.

[0078] like Figure 5 As shown, the clamping groove is an arc-shaped clamping groove adapted to the positioning ring 80, which can accommodate the positioning ring 80. Before the positioning ring 80 is clamped, the positioning ring 80 has been limited in the clamping groove. When the distance sensor 232 detects that the steel pipe 70 advances to a specified distance, the distance result is fed back to the controller, and the controller controls the hoop assembly 40 to clamp the positioning ring 80 to the outer periphery of the steel pipe 70.

[0079] See also Fig. 9 and Fig.11 In some possible embodiments, the positioning assembly 50 includes a fixed block 51, a movable rod 52, and a driving mechanism 53. The fixed block 51 is connected to the base 21, and a third receiving groove 511 is provided on the upper surface of the fixed block 51; the movable rod 52 is rotatably disposed in the third receiving groove 511, and the movable rod 52 has a stopping posture and a releasing posture. When in the stopping posture, the movable rod 52 can extend out of the third receiving groove 511 and stop and limit the buckle 90, and when in the releasing posture, the movable rod 52 can be retracted into the third receiving groove 511 to allow the buckle 90 to pass; the driving mechanism 53 is disposed on the fixed block 51, and is used to drive the movable rod 52 to switch between the stopping posture and the releasing posture.

[0080] The driving mechanism 53 may be a motor connected to the rotating shaft of the fixed block 51, and may drive the movable rod 52 to rotate through gear transmission, chain transmission, etc., so that the movable rod 52 switches between the stopping posture and the releasing posture.

[0081] In some possible embodiments, the positioning assembly 50 further includes a force sensor, which is disposed on a side of the movable rod 52 for contacting the buckle 90 , and is used to detect the pressure applied by the buckle 90 and the movable rod 52 .

[0082] The force sensor can be a piezoelectric, capacitive or other type of sensor that can accurately measure the pressure. When the pressure detected by the force sensor is small and does not reach the set threshold, it means that the positioning ring 80 has not yet contacted the buckle 90. At this time, the mobile vehicle 23 continues to pull the steel pipe 70 forward. When the force sensor detects that the pressure reaches the set threshold, it means that the positioning ring 80 has abutted against the buckle 90, and the buckle 90 and the steel pipe 70 are already in the position where welding is required. At this time, the mobile vehicle 23 and the feeding assembly 10 both stop moving, and the lifting rod of the welding assembly 60 drives the welding head 61 to descend, so that the welding head 61 and the weld are aligned, and the weld is welded. During welding, the clamping mechanism 231 drives the steel pipe 70 to rotate, so that the welding head 61 welds the entire circular weld.

[0083] In this embodiment, the welding head 61 is arranged above the steel pipe 70, and the positioning assembly 50 is arranged below the steel pipe 70. The two are arranged relative to each other. The welding slag during welding is not easy to splash onto the movable rod 52, and it does not need to be cleaned frequently, which helps to ensure the long-term and reliable operation of the positioning assembly 50.

The specific contents of each combination embodiment will not be repeated here. After this description, it can be considered that the specification of the present invention has recorded various combination embodiments and can support different combination embodiments.
