[0002] The tee is an important component of the tent frame. It is mainly used to connect different poles in the tent, and plays a role of fixing and supporting, so that the tent can form a stable structure. The tee is usually prepared by welding two pipes, in which one end of one pipe needs to be cut and formed into an arc-shaped notch that can fit with the outer circumference of the other pipe. When welding, the arc-shaped notch is fitted against the peripheral side wall of the middle position of the other pipe, and then the two are welded and fixed using welding equipment.

[0003] Welding equipment usually includes a clamp and a welding robot arm; the welding robot arm is a linkage mechanism with a welding head at the end for welding and multiple degrees of freedom. The welding robot arm can drive the welding head to weld different positions of the weldment according to a preset program.

It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but such information should not be limited to these terms, which are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0061] The tee is an important component of the tent support, which is mainly used to connect different poles of the tent, and plays a role of fixing and supporting, so that the tent can form a stable structure; the tee is usually prepared by welding two pipes. In this application, the first pipe 9 and the second pipe 10 (which are aluminum alloy structural parts) are used as examples for explanation. It is necessary to cut and form an arc-shaped notch 101 (such as Fig.13 As shown), the arc-shaped notch 101 can fit against the peripheral side wall of the first pipe 9, and then welding is performed at the fitting point of the arc-shaped notch 101 and the first pipe 9 by welding equipment, so as to finally realize the welding connection between the first pipe 9 and the second pipe 10 and form a three-way pipe.

[0062] Currently, during the welding process, workers are required to manually position the pipe fittings so that the pipe fittings are in the preset welding position. In addition, the operating surface of the welding robot arm is located on the same side of the two pipe fittings, and can only weld the same side of the connection of the two pipe fittings. When welding on the other side is required, workers are required to manually remove the pipe fittings from the fixture and flip the two pipe fittings half a circle (180°) before welding the other side through the welding robot arm. After completing all the welding operations, the welded pipe fittings must be manually removed from the fixture.

[0063] Reference Figure 1-Figure 14 As shown, based on the above situation, on the first aspect, an embodiment of the present application proposes an automated welding device for a tent support, which is used to weld a first pipe 9 and a second pipe 10. The automated welding device for the tent support has X and Y directions perpendicular to each other, and includes: a frame 1 and a supporting frame 2, and the supporting frame 2 is rotatably arranged on the frame 1; illustratively, a driving motor 11 may be provided on the frame 1, and the driving motor 11 drives the supporting frame 2 to rotate relative to the frame 1.

[0064] like Figure 3As shown, the first clamping part 3 is fixedly arranged on the carrier 2, and two first clamping parts 3 are provided. The two first clamping parts 3 are arranged at intervals along the X direction to form a gap between the two first clamping parts 3, and the gap forms an operating space for welding the welding assembly 8; first annular clamping members 5 are respectively provided in the two first clamping parts 3, and the two first annular clamping members 5 are coaxially arranged, wherein one first annular clamping member 5 is used to clamp one end of the first pipe 9, and the other first annular clamping member 5 is used to clamp the other end of the first pipe 9, and the first pipe 9 is clamped and positioned by the cooperation of the two first annular clamping members 5; the first annular clamping member 5 has a clamping center, referring to Figure 3 As shown, the line L1 is continuous between the clamping centers of the two first annular clamping members 5 , that is, when the two first annular clamping members 5 complete the clamping and positioning of the first pipe 9 , the axial center line of the first pipe 9 coincides with the line L1 .

[0065] The second clamping portion 6 is arranged on the carrier 2 and moves along the Y direction. In the Y direction, the second clamping portion 6 is located on the same side of the two first clamping portions 3. The second clamping portion 6 has a rotatable second annular clamping member 7, such as Figure 3 As shown, the rotation axis of the second annular clamping member 7 extends along the Y direction, and the clamping center of the second annular clamping member 7 is located on the perpendicular bisector of the line connecting the clamping centers of the two first annular clamping members 5; Figure 3 The line L1 is the connecting line of the clamping centers of the two first annular clamping members 5, and the line L2 is the perpendicular bisector of the connecting line (L1) of the clamping centers of the two first annular clamping members 5; that is, the clamping center of the second annular clamping member 7 is located on the line L2; wherein the second annular clamping member 7 is used to clamp and position the second pipe 10, and when the second annular clamping member 7 completes the clamping and positioning of the second pipe 10, the axial center line of the second pipe 10 is colinear with the line L2.

[0066] Reference Figure 4 , Figure 5 As shown, the push member 33 is arranged in the first clamping part 3 along the X direction. In the X direction, the push member 33 is arranged on the side of the first annular clamping member 5 away from the working space; the push member 33 has an initial position away from the working space (such as Figure 4 As shown) and the adjustment position close to the working space, the pushing member 33 moves from the initial position to the adjustment position, which is used to adjust the first pipe 9 to the preset position; in the present application, the adjustment position of the pushing members 33 in the two first clamping parts 3 can be calibrated according to the length of the first pipe 9 to be welded, so that when the two pushing members 33 are respectively moved from the initial position to the adjustment position, the bisector line of the first pipe 9 in the length direction thereof coincides with the line L2, that is, the axial center lines of the first pipe 9 and the second pipe 10 are in the same plane and the axial center line of the second pipe 10 divides the first pipe 9 into equal parts.

[0067] The welding assembly 8 is arranged on the frame 1, and the welding assembly 8 includes a welding robot arm and a welding head arranged at the end of the welding robot arm, wherein the welding robot arm is composed of a connecting rod mechanism with multiple degrees of freedom. The welding robot arm can drive the welding head to weld the arc notch 101 of the second pipe fitting 10 and the abutment of the first pipe fitting 9 according to a preset program.

[0068] In the specific implementation of this embodiment, firstly, the end of the second pipe 10 without the arc-shaped notch 101 is inserted into the second clamping portion 6, and the second pipe 10 is clamped and positioned by the second annular clamping member 7 provided in the second clamping portion 6, so that the axial center line of the second pipe 10 coincides with the line L2; then, the two ends of the first pipe 9 are respectively placed into the corresponding first clamping portion 3, and the pushing member 33 is driven to move from the initial position to the adjustment position. In the process of the two pushing members 33 moving from the initial position to the adjustment position, the first pipe 9 is synchronously driven to move to the preset position, so that when the two pushing members 33 move to the adjustment position, the first pipe 9 is synchronously moved to the preset position, referring to Figure 3 As shown, at this time, the line L2 divides the first pipe 9 into equal parts; secondly, the second clamping portion 6 is driven to move along the Y direction toward the working space or the first pipe 9, and the second annular clamping member 7 is driven to rotate during the movement to adjust the angle of the arc-shaped notch 101 on the second pipe 10, so that the arc-shaped notch 101 of the second pipe 10 can fit against the peripheral side wall of the first pipe 9, refer to Figure 1 As shown, at this time, the contact position between the arc notch 101 of the second pipe fitting 10 and the first pipe fitting 9 is the middle position of the first pipe fitting 9. At this time, the first pipe fitting 9 and the second pipe fitting 10 are both in the preset welding position. Finally, the arc notch 101 of the second pipe fitting 10 and the surrounding side wall of the first pipe fitting 9 are welded by the welding assembly 8. The welding assembly 8 in the present application can perform welding operations on the first pipe fitting 9 and the second pipe fitting 10 in the preset welding position through a preset program, that is, only when the first pipe fitting 9 and the second pipe fitting 10 are in the preset welding position, the preset program will control the welding robot arm to drive the welding head to weld the first pipe fitting 9 and the second pipe fitting 10 along the preset welding trajectory.

[0069] It should be noted that: the welding range of the welding assembly 8 can only cover one side area of ​​the arc-shaped notch 101 of the second pipe fitting 10 and the side wall of the first pipe fitting 9, and the welding operation is performed on this area. After the welding operation on one side is completed, the driving motor 11 drives the support frame 2 to rotate relative to the frame 1, that is, after rotating half a circle, the other side of the arc-shaped notch 101 of the second pipe fitting 10 and the side wall of the first pipe fitting 9 is exposed to the welding range of the welding assembly 8, and the welding operation can be performed on this side; it is worth noting that: when the driving motor 11 drives the support frame 2 to rotate relative to the frame 1, the welding assembly 8 needs to adjust its position (so that its welding head is not on the rotation trajectory of the support frame 2) to avoid the rotation adjustment of the support frame 2; after the welding assembly 8 completes the welding operation on the other side, the welding operation on the first pipe fitting 9 and the second pipe fitting 10 is completed.

[0070] In order to achieve coordinated cooperation in the above-mentioned action process, the welding assembly 8, the first clamping part 3, the second clamping part 6, and the drive motor 11 in the present application are all electrically connected to a controller, and the controller controls the coordinated work between the above-mentioned components to jointly complete the welding operation of the first pipe fitting 9 and the second pipe fitting 10.

[0071] Reference Figure 2 , Figure 3 As shown, in some embodiments of the present application, the first clamping portion 3 includes a first half cylinder 31, which is fixed on the support frame 2; and a second half cylinder 32, which is located above the first half cylinder 31 and is spliced ​​with the first half cylinder 31 to form a cylindrical body, and in the X direction, the second half cylinder 32 is moved along the splicing point and connected to the first half cylinder 31; illustratively, the first half cylinder 31 and the second half cylinder 32 in this embodiment need to have the characteristics of high temperature resistance and high hardness, and can be metal structures or composite materials structures, wherein the first half cylinder 31 can be fixed to the support frame 2 by welding or fixedly installed on the support frame 2 by fasteners, and the fixing method of the first half cylinder 31 is not limited in this embodiment.

[0072] In this embodiment, the push member 33 is connected to the first half cylinder 31 and moves along the X direction. Figure 4 As shown, a guide groove extending along the X direction is provided in the first half cylinder 31, and the bottom of the pushing member 33 is slidably assembled in the guide groove, thereby realizing the movement of the pushing member 33 along the X direction on the first half cylinder 31, so that it can move between the initial position and the adjustment position; when the pushing frame is at the end of the guide groove away from the working space, it is in the initial position, and when the pushing frame is at the end of the guide groove close to the working space, it is in the adjustment position.

[0073] The second half cylinder 32 is connected to the first half cylinder 31 by movement along the X direction, so that the second half cylinder 32 has an avoidance position away from the working space and a working position close to the working space. Figure 3As shown, when the second half-cylinder 32 is in the avoidance position (at this time, the push piece 33 is in the initial position), the first pipe 9 can be placed from top to bottom into the two first half-cylinders 31 (at this time, the first pipe 9 is supported by the first annular clamp 5), that is, the two ends of the first pipe 9 along its length direction are respectively located in the corresponding first half-cylinders 31; since no precise alignment operation is performed, the first pipe 9 at this time is almost not in the preset welding position (the position of the first pipe 9 is either biased towards the first half-cylinder 31 close to the left side, or biased towards the first half-cylinder 31 close to the right side), and then the first pipe 9 is placed on the two first half-cylinders 31. The two pushing members 33 are moved from the initial position to the adjustment position. During the movement of the two pushing members 33 from the initial position to the adjustment position, one of the pushing members 33 will abut against one end of the first pipe 9 in the length direction and drive the first pipe 9 to move to the preset welding position (along the X direction). When both pushing members 33 move to the adjustment position, the two ends of the first pipe 9 in the length direction abut against the corresponding pushing members 33, and the first pipe 9 is in the preset welding position (the line L2 divides the first pipe 9 into equal parts). Then, the two second half cylinders 32 are driven to move from the avoidance position to the working position, that is, Figure 3 Move the position shown in Figure 2 In this embodiment, the push member 33 is moved from the initial position to the adjustment position and the second half cylinder 32 is moved from the avoidance position to the working position can be performed successively or simultaneously, which is not limited in this embodiment.

[0074] After the above process is completed, the first annular clamp 5 is used to clamp and position the first pipe 9 at the preset welding position, and the position adjustment and positioning of the first pipe 9 are completed.

[0075] Reference Figure 4 , Figure 5 , Figure 6 As shown, in some embodiments of the present application, the first annular clamp 5 includes a plurality of first telescopic rods 51 extending radially along the cylindrical body, each first telescopic rod 51 is telescoped radially along the cylindrical body, and the first telescopic rod 51 can be a hydraulic rod or an electric rod; the elongation of the first telescopic rod 51 is set accordingly according to the outer diameter of the first pipe 9 to be processed and the elongation of each first telescopic rod 51 is consistent, so that when each first telescopic rod 51 is extended by the set elongation, each first telescopic rod 51 abuts against the outer periphery of the first pipe 9 and enables the axial center line of the first pipe 9 to coincide with the line L1 (that is, when each first telescopic rod 51 is extended by the set elongation, the axial center line of the first pipe 9 coincides with the clamping center of the first annular clamp 5).

[0076] Exemplarily, in this embodiment, at least two first telescopic rods 51 are provided on the first half cylinder 31 (the two first telescopic rods 51 are arranged at intervals), and at least one first telescopic rod 51 is provided on the second half cylinder 32. Figure 6 As shown, in this embodiment, three first telescopic rods 51 are provided as an example for explanation; the reason why at least two first telescopic rods 51 are provided on the first half cylinder 31 is that when the two second half cylinders 32 are in the avoidance position and the first pipe 9 is placed into the first half cylinder 31 from top to bottom, the two first telescopic rods 51 provided on the first half cylinder 31 can realize reliable support and support for the first pipe 9 (at this time, the axial center line of the first pipe 9 is located below the line L1); when the push member 33 abuts against one of the first pipes 9 in the length direction, the push member 33 is in the position of the first pipe 9. When the end portion drives the first pipe fitting 9 to move to the preset welding position, the first pipe fitting 9 can move under the support of at least two first telescopic rods 51; when the second half-cylinder 32 moves from the avoidance position to the working position, the first telescopic rod 51 arranged on the second half-cylinder 32 also moves to the position corresponding to the two first telescopic rods 51 arranged on the first half-cylinder 31. At this time, each first telescopic rod 51 is controlled to extend by a preset extension amount, so that the first pipe fitting 9 can be centered, that is, the axial center line of the first pipe fitting 9 is made to be collinear with the line L1.

[0077] Preferably, the first telescopic rods 51 in the present embodiment are arranged at equal intervals around the circumference of the cylindrical body, so that the clamping force applied to the first pipe 9 by the first telescopic rods 51 is balanced and uniform, so as to ensure that the first pipe 9 can be stably maintained in the current position; at the same time, a clamping member is provided at the telescopic end of the first telescopic rod 51 (the side of the clamping member in contact with the first pipe 9 is rough and made of a material with a large friction coefficient), which is used to increase the friction resistance between the first pipe 9 and the first telescopic rod 51, thereby improving the clamping and positioning effect.

[0078] In this embodiment, in order to increase the contact surface between the push member 33 and the end of the first pipe member 9 (so as to evenly distribute the push force between the two), a plurality of extension rods 332 (such as Figure 4 As shown), and in the X direction, the extension rod 332 and the first telescopic rod 51 located on the second half cylinder 32 are staggered to prevent the extension rod 332 from touching the first telescopic rod 51 located on the second half cylinder 32 during the movement of the second half cylinder 32 between the working position and the avoidance position.

[0079] Reference Figure 4 , Figure 5 , Figure 6As shown, in some embodiments of the present application, the automated welding device of the tent support further includes a first electromagnetic driving component 4 provided on the first half cylinder 31, the first electromagnetic driving component 4 being used to drive the second half cylinder 32 to move between the avoidance position and the working position; and / or the first electromagnetic driving component 4 being used to drive the pushing component 33 to move between the initial position and the adjustment position.

[0080] Exemplarily, the first electromagnetic driving component 4 in the present embodiment is an electromagnet, and whether the first electromagnetic driving component 4 has electromagnetic force is controlled by controlling whether current flows through the electrical circuit of the electromagnet, and the magnetic poles (i.e., the N pole and the S pole) of the first electromagnetic driving component 4 are controlled by controlling the direction of the current flowing through the electromagnet; the first electromagnetic driving component 4 in the present embodiment can be used to drive the second half cylinder 32 to move between the avoidance position and the working position; or to drive the pushing component 33 to move between the initial position and the adjustment position; or to simultaneously drive the second half cylinder 32 to move between the avoidance position and the working position and drive the pushing component 33 to move between the initial position and the adjustment position; as a preferred embodiment, the present embodiment adopts the method of simultaneously driving the second half cylinder 32 to move between the avoidance position and the working position and driving the pushing component 33 to move between the initial position and the adjustment position through the first electromagnetic driving component 4, thereby saving the setting of driving components and reducing costs.

[0081] In this embodiment, the second half cylinder 32 and the push member 33 are both provided with a structural member that can respond to the electromagnetic force and thus interact with the electromagnetic force generated by the first electromagnetic driving member 4, and drive the second half cylinder 32 and the push member 33 to move; and when the magnetic pole direction of the first electromagnetic driving member 4 changes, the structural member can interact with the electromagnetic force to drive the second half cylinder 32 and the push member 33 to move in the opposite direction.

[0082] Reference Figure 6 As shown, in some embodiments of the present application, the second half cylinder 32 has a stopper 321 at one end away from the working space, and the stopper 321 is used to limit the distance that the second half cylinder 32 moves in the X direction toward the working space (when the stopper 321 abuts against the end of the first half cylinder 31 away from the working space, the first half cylinder 31 and the second half cylinder 32 remain flush toward the working space); refer to Figure 4 , Figure 5 As shown, a mounting portion 312 is provided at one end of the first half cylinder 31 away from the working space, and the first electromagnetic driving member 4 is provided on the mounting portion 312 and the first electromagnetic driving member 4 is provided along the X direction through the mounting portion 312; Figure 6As shown, a slider 3121 is provided at the upper end of the mounting portion 312, and a slide groove 323 cooperating with the slider 3121 is provided on the inner wall of the second half cylinder 32. The slide groove 323 is provided in part of the inner wall of the second half cylinder 32 along the X direction. The cooperation of the slide groove 323 and the slider 3121 is used to limit the distance that the second half cylinder 32 moves in the X direction away from the working space (to avoid separation between the first half cylinder 31 and the second half cylinder 32).

[0083] In this embodiment, Figure 5 As shown, a second magnet 331 is provided on the side of the push member 33 facing the mounting portion 312, referring to Figure 6 As shown, a first magnet 3211 is provided on the side of the stopper 321 facing the mounting portion 312, and the magnetic pole of the first magnet 3211 facing the mounting portion 312 is set to be the same as the magnetic pole of the second magnet 331 facing the mounting portion 312; the following description is taken as an example that the magnetic poles of the first magnet 3211 and the second magnet 331 facing the mounting portion 312 are both S poles; when the first electromagnetic driving component 4 is energized, the side of the first electromagnetic driving component 4 facing the stopper 321 is the N pole, and the side facing the pushing component 33 is the S pole. At this time, the first electromagnetic driving component 4 can simultaneously drive the second half cylinder 32 and the pushing component 33 to move in a direction close to the working space (even if the second half cylinder 32 is moved from the avoidance position to the working position, so that the pushing component 33 is moved from the initial position to the adjustment position), at this time, there is a magnetic attraction between the first electromagnetic driving component 4 and the first magnet 3211, and there is a magnetic repulsion between the first electromagnetic driving component 4 and the second magnet 331.

[0084] Reference Figure 7 , Figure 8 , Fig. 9 , Fig.10 As shown, in some embodiments of the present application, the second clamping portion 6 includes a clamping cylinder, which is connected to the supporting frame 2 for movement along the Y direction. Exemplarily, the clamping cylinder has a plurality of guide rods 65 arranged at intervals along the circumference of the clamping cylinder on the side away from the working space, and guide holes (not numbered in the figure) cooperating with each guide rod 65 are provided on the supporting frame 2, and the guide rods 65 are passed through the guide holes to realize the movement of the clamping cylinder relative to the supporting frame 2 in the Y direction.

[0085] The clamping cylinder has an inlet and outlet 61 connected to the working space on the side facing the working space, and the inlet and outlet 61 is used to allow the second pipe 10 to enter and exit the clamping cylinder. The end of the clamping cylinder away from the working space is closed (to form a closed end); an annular cylinder 62 is coaxially rotated in the clamping cylinder, and the second annular clamping member 7 is arranged in the annular cylinder 62. When the annular cylinder 62 is driven to rotate relative to the clamping cylinder, the second annular clamping member 7 can be driven to rotate synchronously (to adjust the circumferential angle); refer to Fig.10As shown, at least two groups of second annular clamps 7 are arranged in the Y direction in the clamping cylinder, and at least two groups of second annular clamps 7 are arranged at intervals in the Y direction (the two groups of second annular clamps 7 arranged at intervals are used to achieve reliable clamping and positioning of the second pipe 10), each group of second annular clamps 7 includes at least three second telescopic rods 71, and at least three second telescopic rods 71 ​​are arranged at equal intervals around the axial direction of the clamping cylinder; illustratively, the second telescopic rod 71 can be a hydraulic rod or an electric rod, and the elongation of the second telescopic rod 71 is set accordingly according to the outer diameter of the second pipe 10 to be processed and each second telescopic rod The elongation of the second telescopic rods 71 ​​is consistent, so that when each second telescopic rod 71 is extended by the set elongation, each second telescopic rod 71 abuts against the outer periphery of the second pipe fitting 10 and makes the axial center line of the two pipe fittings coincide with the line L2 (that is, when each second telescopic rod 71 is extended by the set elongation, the axial center line of the second pipe fitting 10 coincides with the clamping center of the second annular clamping member 7); in order to increase the friction resistance between the telescopic end of the second telescopic rod 71 and the second pipe fitting 10, a clamping pad is provided at the telescopic end of the second telescopic rod 71, and the clamping pad is rough on the side facing the second pipe fitting 10 and is made of a material with a large friction coefficient.

[0086] In this embodiment, when the clamping tube is in the initial position, the end of the second pipe fitting 10 without the arc-shaped notch 101 is fed into the clamping tube through the inlet and outlet 61, and the end of the second pipe fitting 10 without the arc-shaped notch 101 is abutted against the closed end of the clamping tube away from the working space, and then the second pipe fitting 10 is clamped and positioned by the second annular clamping member 7 (at this time, the axial center line of the second pipe fitting 10 coincides with the line L2); then the clamping tube is driven to move from the initial position to the working position, and the angle of the arc-shaped notch 101 of the second pipe fitting 10 is continuously adjusted during the movement, so that when the clamping tube moves to the working position, the arc-shaped notch 101 of the second pipe fitting 10 can just fit and abut against the circumferential side wall of the first pipe fitting 9 (so that part of the circumferential outer side wall of the first pipe fitting 9 is just embedded in the arc-shaped notch 101).

[0087] In traditional operations, the clamp also has an initial position and a working position, that is, when the clamp is in the initial position, it is used to clamp and position the pipe fitting, and then the clamp is moved to the working position for welding. However, since the arc-shaped notch 101 on the second pipe fitting 10 needs to fit the circumferential outer wall of the first pipe fitting 9, it is necessary to adjust the angle of the second pipe fitting 10 so that the arc-shaped notch 101 can just fit the circumferential outer wall of the first pipe fitting 9; if the worker first clamps and positions the second pipe fitting 10 with the clamp, then when the clamp is moved close to the working position, it is necessary to loosen the clamp to adjust the angle of the second pipe fitting 10 (repeatedly operating the clamp results in low efficiency and cumbersome operation); or the worker holds the second pipe fitting 10 and directly fits the arc-shaped notch 101 against the circumferential outer wall of the first pipe fitting 9 circumferential outer wall, and then drive the clamp to move to the working position and clamp and position the second pipe 10. However, during this operation, it is very easy for the clamp to accidentally touch the worker's hands or limbs due to improper operation, which poses a great safety hazard. In this embodiment, the second annular clamp 7 is arranged in an annular tube 62 that can rotate relative to the clamping tube, so that the second pipe 10 can be clamped and positioned first, and then while driving the clamping tube to move from the initial position to the working position, the annular tube 62 is rotated to adjust the angle of the arc-shaped notch 101 of the second pipe 10, so that it can fit and abut against the circumferential outer wall of the first pipe 9 when it moves to the working position. The second annular clamp 7 only needs to be operated once during the whole process, and the occurrence of accidental injuries to the workers' hands and limbs is greatly reduced.

[0088] After completing the clamping and positioning of the first pipe fitting 9 and the second pipe fitting 10, the arc notch 101 of the second pipe fitting 10 and the abutment of the first pipe fitting 9 can be welded by the welding assembly 8. After completing the welding of the arc notch 101 of the second pipe fitting 10 and the one side area of ​​the abutment of the first pipe fitting 9, the driving motor 11 drives the support frame 2 to rotate half a circle, so that the arc notch 101 of the two pipe fittings and the other side area of ​​the abutment of the first pipe fitting 9 are exposed to the welding operation range of the welding assembly 8, so that during the welding process, the welding operation between the first pipe fitting 9 and the second pipe fitting 10 can be completed without adjusting the position of the two pipe fittings, which reduces the labor intensity of the staff and avoids the problem of reduced welding accuracy caused by frequent disassembly of the first pipe fitting 9 and the second pipe fitting 10. At the same time, it also improves the welding efficiency of the welding assembly 8, which is conducive to mass manufacturing and processing of workpieces.

[0089] In this embodiment, after the welding operation of the first pipe 9 and the second pipe 10 is completed, the position relationship of the support frame 2 relative to the frame 1 is as follows: Fig.11 The state shown in the left station in the middle, the specific unloading process is as follows:

[0090] A1: First, release the clamping position of the second annular clamping member 7 on the second pipe 10, and drive the clamping cylinder to move from the working position to the unloading position, that is, Fig.12 The position shown in b is moved to Fig.12 c, when the clamping tube is in Fig.12 At the unloading position shown in c, the second pipe 10 has been completely removed from the clamping tube;

[0091] A2: Then release the clamping and positioning of the first annular clamping member 5 on the first pipe 9, adjust the direction of the current flowing through the first electromagnetic driving member 4, so that the first electromagnetic driving member 4 becomes the S pole on the side facing the stop portion 321, and becomes the N pole on the side facing the mounting portion 312. At this time, there is a magnetic repulsive force between the first electromagnetic driving member 4 and the first magnet 3211, and there is a magnetic attractive force between the first electromagnetic driving member 4 and the second magnet 331, thereby synchronously driving the second half cylinder 32 to move toward the avoidance position and the pushing member 33 to move toward the initial position; because the two second half cylinders 32 are located below the first half cylinder 31 at this time, when the two second half cylinders 32 are moved to the avoidance position, the first pipe 9 and the second pipe 10 that have been welded and maintained as a whole fall under the action of gravity (a conveyor belt or a collection box can be provided under the frame 1 for transporting or collecting the welded pipes), thereby realizing the automatic unloading process of the pipes.

[0092] In this embodiment, after the welding operation on the pipe fittings is completed, the welded pipe fittings can be automatically unloaded from the support frame 2 without the need for manual unloading by the staff, thereby avoiding direct contact between the staff and the welded pipe fittings, and minimizing the risk of the staff being burned by high temperature (when the pipe fittings are welded, the temperature of the pipe fittings rises sharply due to the heat generated during welding).

[0093] Reference Figure 7 , Figure 8 As shown, in some embodiments of the present application, the automatic welding device of the tent support further includes a second electromagnetic driving member 21. For example, the second electromagnetic driving member 21 is an electromagnet. Whether the second electromagnetic driving member 21 has an electromagnetic force is controlled by controlling whether current flows through the electrical circuit of the electromagnet. The magnetic poles (i.e., the N pole and the S pole) of the second electromagnetic driving member 21 are controlled by controlling the direction of the current flowing through the electromagnet. Fig. 9As shown, a third magnet 63 is provided on the side of the clamping cylinder facing the second electromagnetic driving member 21 (that is, the closed end), and a plurality of third magnets 63 may be provided and the plurality of third magnets 63 are arranged at intervals along the circumference of the clamping cylinder; in the present embodiment, by controlling whether current is passed through the second electromagnetic driving member 21 and the direction of the passed current, whether the second electromagnetic driving member 21 has electromagnetic force and the direction of the magnetic pole of the second electromagnetic driving member 21 are controlled, thereby driving the clamping cylinder to move between the initial position, the working position and the unloading position (the specific driving principle is the same as the principle of the first electromagnetic driving member 4 driving the second half cylinder 32 and the pushing member 33, and no further description is given here).

[0094] In this embodiment, when the clamping cylinder is in the initial position, no current flows in the second electromagnetic driving member 21 and no electromagnetic force is generated. In order to enable the clamping cylinder to be stably maintained in the initial position, Figure 7 , Figure 8 As shown, an elastic member 67 (spring) is sleeved on each guide rod 65 , one end of the elastic member 67 abuts against the clamping cylinder, and the other end abuts against the support frame 2 , so that the clamping cylinder can be stably maintained in the working position under the action of the elastic member 67 .

[0095] After the clamping and positioning of the second pipe fitting 10 is completed, the second electromagnetic drive member 21 is controlled to be energized and generate a magnetic repulsion force with the third magnet 63, thereby driving the clamping cylinder to move from the initial position to the working position. During the movement, the annular cylinder 62 is driven to rotate to adjust the angle of the arc-shaped notch 101 of the second pipe fitting 10, so that when the clamping cylinder moves to the working position, the arc-shaped notch 101 on the second pipe fitting 10 can just fit and abut against the circumferential outer wall of the first pipe fitting 9.

[0096] After completing the welding operation, when unloading is required, adjust the direction of the current passed into the second electromagnetic drive component 21, so that the magnetic pole direction of the second electromagnetic drive component 21 is adjusted, so that there is magnetic attraction between the second electromagnetic drive component 21 and the fourth magnet, and then drive the clamping cylinder to cross the initial position from the working position and move to the unloading position to complete the unloading operation.

[0097] Reference Figure 8 , Fig.10 As shown, in some embodiments of the present application, the automated welding device for the tent support further includes a third driving member 64. As an example, the third driving member 64 is a motor. The third driving member 64 is used to drive the annular cylinder 62 to rotate relative to the clamping cylinder. When the clamping cylinder moves from the initial position to the working position, the third driving member 64 is used to adjust the angle of the arc-shaped notch 101 of the second pipe 10 so that the arc-shaped notch 101 of the second pipe 10 fits against the first pipe 9. Specifically, as Figure 8As shown, a gear system 641 is provided in the circumferential direction of the annular cylinder 62 (a cavity for accommodating the gear system 641 is provided in the cylinder wall of the clamping cylinder, and when the annular cylinder 62 rotates relative to the clamping cylinder, the gear system 641 can rotate synchronously in the cavity), and a gear 642 meshing with the gear system 641 is rotatably installed on the outer wall of the clamping cylinder (a hole connected to the cavity is opened on the cylinder wall of the clamping cylinder, and the hole allows the gear 642 to mesh with the gear system 641 located in the cavity), and a third driving member 64 is fixedly installed on the outer wall of the clamping cylinder and is used to drive the gear 642 to rotate.

[0098] In the present embodiment, preferably, a rotating plate 68 is coaxially rotatable at the closed end of the clamping cylinder (a bearing is provided between the rotating plate 68 and the clamping cylinder to make the rotating plate 68 rotate more smoothly relative to the clamping cylinder), and both ends of the rotating plate 68 in the Y direction are flush with the closed end; that is, the end of the second pipe fitting 10 that is not provided with the arc-shaped notch 101 can abut against the rotating plate 68, and when the third driving member 64 drives the annular cylinder 62 to rotate relative to the clamping cylinder, the second pipe fitting 10 can synchronously drive the rotating plate 68 to rotate relative to the clamping cylinder under the clamping action of the second annular clamping member 7, thereby avoiding relative movement between the second pipe fitting 10 and the second annular clamping member 7 due to excessive friction between the second pipe fitting 10 and the closed end during the rotation of the annular cylinder 62.

[0099] Reference Figure 7 , Figure 8 As shown, in some embodiments of the present application, the automated welding device of the tent support further includes a detection component, and the detection component and the third drive member 64 are electrically connected to the control module; the detection component is used to collect the position of the clamping cylinder, and the control module is used to receive the position information of the clamping cylinder, and the third drive member 64 drives the annular cylinder 62 to rotate counterclockwise or clockwise according to the position information of the clamping cylinder, so that the clamping cylinder moves to the working position, and the control module controls the third drive member 64 to stop working.

[0100] Specifically, each guide rod 65 is provided with an abutment plate 66 at one end extending out of the carrier frame 2, and a detection component is provided on the side of the abutment plate 66 facing the clamping cylinder; illustratively, the detection component can be a contact sensor or a distance sensor; when the clamping cylinder is in the initial position, the guide rod 65 is provided with an abutment plate 66 at one end extending out of the carrier frame 2 in a direction away from the clamping cylinder by a distance (that is, the distance between the side of the abutment plate 66 facing the carrier frame 2 and the carrier frame 2, and the distance is set to S); in this embodiment, it is assumed that the second pipe 10 is not provided with an arc-shaped notch 1 When one end of 01 abuts against the rotating plate 68, when the arc-shaped notch 101 of the second tube 10 is fitted and abutted against the circumferential outer wall of the first tube 9, that is, the clamping tube moves from the initial position to the working position (at this time, the arc-shaped notch 101 of the second tube 10 just abuts against the circumferential outer wall of the first tube 9), the distance moved is also S, thereby the distance between the abutment plate 66 and the supporting frame 2 can be detected by the detection component to determine whether the arc-shaped notch 101 of the second tube 10 is fitted and abutted against the circumferential outer wall of the first tube 9.

[0101] In this embodiment, during the process in which the second electromagnetic driving member 21 generates electromagnetic force and cooperates with the third magnet 63 to drive the clamping cylinder to move to the working position, if the detection component detects that there is still a distance between the abutment plate 66 and the carrier frame 2, it indicates that the arc-shaped notch 101 on the second pipe 10 is not able to fit and abut the circumferential outer wall of the first pipe 9 (the circumferential outer wall of the first pipe 9 is not completely embedded in the arc-shaped notch 101). At this time, the control module receives the distance information of the abutment plate 66 detected by the detection component, and controls the third driving member 64 to start and drive the annular cylinder 62 to rotate circumferentially relative to the clamping cylinder (to adjust the arc-shaped notch). 101), specifically: the control module can be set to first control the third driving member 64 to drive the annular cylinder 62 to rotate slightly in the counterclockwise direction. If the detection component detects that the distance between the abutment plate 66 and the support frame 2 tends to decrease, the control module controls the third driving member 64 to drive the annular cylinder 62 to continue to rotate in the counterclockwise direction, until the detection component detects that the movement distance of the abutment plate 66 reaches S (that is, the abutment plate 66 abuts against the support frame 2), indicating that the arc-shaped notch 101 of the second pipe 10 is just in contact with the circumferential outer wall of the first pipe 9, and then the control module controls the third driving member 64 to stop working.

[0102] Or the control module first controls the third driving member 64 to drive the annular cylinder 62 to rotate slightly in the counterclockwise direction. If the detection component detects that the distance between the abutment plate 66 and the support frame 2 tends to increase (indicating that the rotation direction of the second pipe 10 is wrong at this time, and the rotation direction of the second pipe 10 drives the outer wall of the circumferential portion of the first pipe 9 to withdraw from the arc-shaped notch 101, that is, the edge of the arc-shaped notch 101 acts on the outer wall of the first pipe 9 to force the second pipe 10 to move away from the first pipe 9), the control module controls the third driving member 64 to drive the annular cylinder 62 to rotate in the clockwise direction until the detection component detects that the movement distance of the abutment plate 66 reaches S (that is, the abutment plate 66 abuts against the support frame 2), the control module controls the third driving member 64 to stop working.

[0103] In this embodiment, through the cooperation between the detection component, the third drive member 64 and the control module, it can be achieved that when the second electromagnetic drive member 21 drives the clamping cylinder to move from the initial position to the working position, the angle of the arc-shaped notch 101 of the second pipe fitting 10 can be automatically adjusted, and workers are no longer required to manually adjust it, which greatly reduces the labor workload of the staff and also saves the workers more time, so that the workers can be responsible for the welding work of multiple first pipe fittings 9 and second pipe fittings 10 at the same time.

[0104] As a preferred example, Figure 1 , Figure 2As shown, a plurality of workstations (including a carrier frame 2, a first clamping portion 3, a second clamping portion 6, a driving motor 11, etc.) may be arranged on the frame 1, and the plurality of workstations are arranged at intervals along the X direction. The welding assembly 8 is arranged on one side of the frame 1 along the Y direction, and the welding assembly 8 can be moved relative to the frame 1 along the Y direction (a guide rail for moving the welding assembly 8 is provided on the frame 1, and the welding assembly 8 can be moved between different workstations and used to perform welding operations on pipe fittings at different workstations); in this way, one worker can be responsible for multiple workstations, specifically, at one of the workstations H1 On the top, the worker puts the second pipe 10 into the clamping cylinder through the inlet and outlet 61, and then clamps and positions the second pipe 10 through the second annular clamping member 7, then puts the first pipe 9 into the first clamping portion 3 and adjusts the first pipe 9 to the preset welding position through the push member 33, and clamps and positions the first pipe 9 through the first annular clamping member 5; then controls the clamping cylinder to move from the initial position to the working position, and during the movement, drives the annular cylinder 62 to rotate to adjust the angle of the arc notch 101 until the arc notch 101 of the second pipe 10 is formed. 1 and the circumferential outer wall of the first pipe 9 are fitted and abutted, and finally the welding assembly 8 can start the welding operation; preferably, the operation between the above-mentioned components can be completely controlled by the controller (that is, each motor, each electromagnetic drive component, control module and welding assembly 8 are all connected to the controller signal), that is, the worker only needs to put the second pipe 10 into the clamping cylinder and the first pipe 9 into the first half cylinder 31, and the subsequent process is controlled by the controller to control the above-mentioned components to work in coordination; at this time, the worker has time to go to the adjacent workstation H2 and continue to repeat the above-mentioned pipe placement process, While the welding assembly 8 is welding the pipe fittings on the H1 station, the various components on the station H2 work together under the control of the controller to adjust the positions of the first pipe fitting 9 and the second pipe fitting 10, and to enable the arc-shaped notch 101 to fit and abut against the circumferential outer wall of the first pipe fitting 9; after the welding assembly 8 finishes welding the pipe fittings on the H1 station, the welding assembly 8 moves to the H2 station and can continue to weld the pipe fittings on the H2 station, thereby achieving uninterrupted welding operations, greatly improving welding efficiency, and facilitating mass production of workpieces. In specific implementation, the number of stations corresponding to the welding assembly 8 can be adjusted accordingly according to actual conditions, thereby maximizing the efficiency of workpiece production.

[0105] In this embodiment, when the welding assembly 8 moves along the guide rail, a calibration point can be set at the corresponding position of the guide rail and the corresponding workstation, that is, when the welding assembly 8 moves to the calibration point position corresponding to the workstation, the welding assembly 8 stops moving and starts welding; the specific calibration point can be an infrared transmitter set on one side of the guide rail, and the welding assembly 8 is provided with an infrared receiver corresponding to the infrared transmitter (the infrared transmitter and the infrared receiver are both connected to the controller signal). When the welding assembly 8 moves to the above-mentioned calibration point, the infrared receiver receives the infrared signal of the infrared transmitter, and the controller controls the welding assembly 8 to stop moving and perform welding operations on the workpiece on the workstation. It should be noted that the drive motor 11 and the third drive member 64 in this application are both motors with electromagnetic brakes. This motor automatically locks the motor shaft through the electromagnetic brake when power is lost to prevent it from rotating under the action of external force.

[0106] Reference Fig.14 As shown, as a preference, the welding assembly 8 in the present application may also be fixedly mounted on the frame 1, and workstations are provided on both sides of the welding assembly 8. Under this working condition, the welding assembly 8 does not need to move relative to the frame 1. After completing the welding operation of the pipe fittings at the workstation on one side, it only needs to rotate to the other side to perform welding operations on the pipe fittings at the workstation on the other side.

[0107] Reference Figure 4 , Figure 5 , Figure 6 As shown, as a preference, in order to improve the welding quality between the arc-shaped notch 101 of the second pipe 10 and the first pipe 9 by the welding assembly 8, the embodiment of the present application provides a structure capable of pre-cleaning the arc-shaped notch 101 of the first pipe 9 and the second pipe 10 before welding, and the structure can realize cleaning of dust attached to the arc-shaped notch 101 of the first pipe 9 and the second pipe 10; the details are as follows:

[0108] A semicircular ring 322 is coaxially connected to the stopper 321 on one side facing the first half cylinder 31, and a sliding cavity 311 matching the semicircular ring 322 is provided in the cylinder wall of the first half cylinder 31. When the second half cylinder 32 moves between the working position and the avoidance position, the semicircular ring 322 is synchronously driven to move in the sliding cavity 311. It is assumed that when the second half cylinder 32 is in the avoidance position, the semicircular ring 322 does not completely slide out of the sliding cavity 311. At the same time, the mounting portion 312 is set to a circular structure and its outer diameter is the same as the inner diameter of the cylindrical body. A plurality of air holes 3122 are penetrated through the mounting portion 312 along the X direction, and the plurality of air holes 3122 are arranged around the first electromagnetic driving member 4. In this way, When the second half cylinder 32 moves from the avoidance position to the working position under the action of the first electromagnetic driving member 4, the movement of the second half cylinder 32 synchronously drives the stopper 321 to move, so that the gas originally located in the space enclosed by the stopper 321, the semicircular ring 322, the mounting portion 312 and the second half cylinder 32 is blown out toward the working space through the multiple air holes 3122, and then the dust attached to the arc-shaped notch 101 of the first pipe fitting 9 and the second pipe fitting 10 is blown away; thereby, good contact between the welding material and the pipe fitting is achieved, and the mechanical properties of the weld are improved; at the same time, defects such as air holes and incomplete welding caused by the presence of dust during the welding process are also avoided.

[0109] In this embodiment, if Fig.12 As shown in a, it is a state diagram when the second pipe 10 is in the initial position and the first pipe 9 and the second pipe 10 have completed clamping and positioning. At this time, one end of the second pipe 10 with the arc-shaped notch 101 is on the air outlet cross-section of the cylindrical body composed of the first half cylinder 31 and the second half cylinder 32. When the airflow is guided and constrained by the cylindrical body, it can blow to the arc-shaped notch 101 of the first pipe 9 and the second pipe 10, and clean the dust attached to the surface of the above position; in this embodiment, the distance between the arc-shaped notch 101 of the second pipe 10 in the initial position and the line L1 is relatively close, and when the first pipe 9 is placed, a collision may occur between the peripheral side wall of the first pipe 9 and the arc-shaped notch 101; or the second pipe 10 is in the initial position and the first half cylinder 31 and the second half cylinder 32 are formed. When the pipe fitting 9 and the second pipe fitting 10 have completed clamping and positioning, the end of the second pipe fitting 10 with the arc-shaped notch 101 can be slightly away from the line L1. At this time, the arc-shaped notch 101 will slightly deviate from the air outlet cross-section of the cylindrical body composed of the first half cylinder 31 and the second half cylinder 32, resulting in a certain impact on the dust cleaning effect attached to the surface of the arc-shaped notch 101. However, since the distance between the arc-shaped notch 101 and the line L1 is slightly farther, the probability of the peripheral side wall of the first pipe fitting 9 touching the arc-shaped notch 101 is reduced when the first pipe fitting 9 is placed. This embodiment only provides the above two implementation methods. During specific implementation, the distance between the arc-shaped notch 101 and the line L1 when the second pipe fitting 10 is in the initial position can be set accordingly according to actual needs.

[0110] In this embodiment, the arrangement of the first half cylinder 31 and the second half cylinder 32 can also provide guidance and constraints for the movement of the airflow (forming a flow channel for the gas to flow), so that the airflow blown out from the air hole 3122 can be accurately blown to the arc-shaped notch 101 of the first pipe 9 and the second pipe 10 under the guidance of the first half cylinder 31 and the second half cylinder 32; at the same time, the airflow is blown out from the air hole 3122 to form a certain airflow resistance, which can also provide a certain degree of buffering for the movement of the second half cylinder 32, because the first electromagnetic driving member 4 generates an electromagnetic force and is provided at the stop portion When the first magnet 3211 on 321 acts, the magnetic force generated will drive the second half cylinder 32 to move from the avoidance position to the working position at a faster speed. When the second half cylinder 32 moves to the working position at a faster speed, a larger impact force will be generated, which will cause the corresponding structural parts to produce impact deformation over time (affecting the matching accuracy between the various parts); in this embodiment, the airflow resistance formed by the airflow blowing out from the air hole 3122 can just alleviate and improve the above situation, and can reduce the moving speed of the second half cylinder 32 to a certain extent, and reduce the impact force between the structural parts. Similarly, when the second half cylinder 32 moves from the working position to the avoidance position, the external airflow enters from the air hole 3122 into the space surrounded by the stopper 321, the semicircular ring 322, the mounting portion 312, and the second half cylinder 32, which can also reduce the speed of the second half cylinder 32 when it moves from the working position to the avoidance position.

[0111] In a second aspect, an embodiment of the present application provides a welding method, using the automated welding device for the tent support in the above embodiment, comprising the following steps:

[0112] S1: The second pipe 10 is fed into the clamping tube through the inlet and outlet 61, and the end of the second pipe 10 without the arc-shaped notch 101 is brought into contact with the side wall of the clamping tube away from the working space (that is, the closed end of the clamping tube), and the second pipe 10 is clamped and positioned by the second annular clamping member 7;

[0113] S2: driving the second half cylinder 32 to move to the avoidance position, and sending the first pipe 9 from top to bottom into each first half cylinder 31;

[0114] S3: The first electromagnetic driving member 4 drives the pushing member 33 to move from the initial position to the adjustment position, and drives the second half cylinder 32 to move from the avoidance position to the working position; then the first annular clamping member 5 clamps and positions the first pipe member 9;

[0115] S4: driving the clamping tube to move from the initial position to the working position, so that the arc-shaped notch 101 of the second pipe 10 abuts against the first pipe 9;

[0116] S5: welding the arc-shaped notch 101 of the second pipe 10 and one side of the abutment portion of the first pipe 9 by using the welding assembly 8;

[0117] S6: rotating the carrier 2, and continuing to weld the arc-shaped notch 101 of the second pipe 10 and the other side of the abutment between the first pipe 9 through the welding assembly 8;

[0118] S7: After the welding operation is completed, the second annular clamping member 7 is released from the clamping position of the second pipe 10, and the clamping cylinder is driven to move from the working position to the unloading position; then the first annular clamping member 5 is released from the clamping position of the first pipe 9, and the second half cylinder 32 is driven to move from the working position to the avoidance position for unloading.

[0119] In summary, the embodiment of the present invention provides an automatic welding device and a welding method for a tent support. This solution can realize automatic adjustment of the positions of the first pipe 9 and the second pipe 10 by setting a matching first clamping portion 3 and a second clamping portion 6, so that the first pipe 9 and the second pipe 10 are adjusted to a preset welding position; when the arc notch 101 of the second pipe 10 and the one side of the abutment of the first pipe 9 are welded, the carrier frame 2 is rotated to expose the other side to the working range of the welding assembly 8, so that the entire welding operation can be completed without re-adjusting the positions of the first pipe 9 and the second pipe 10; the above process does not require manual intervention, improves welding efficiency and reduces the labor burden of the staff; and after the welding operation is completed, the second half cylinder 32 is driven to move from the working position to the avoidance position, and the second clamping portion 6 is driven to move from the working position to the unloading position, so that the pipe can be automatically unloaded without the need for manual operation by the worker, thereby avoiding the occurrence of burns to the staff due to the increase in temperature of the pipe during welding.

[0120] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
