[0033] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] See also Figures 1 to 9As shown, an automated welding equipment for factory-prefabricated long components comprises a workbench 1, a mounting frame 2, a shape-adjusting mechanism 3, a fixing mechanism 4 and a welding mechanism 5; the mounting frame 2 is arranged at the center of the workbench 1, and two rings 21 are arranged on the mounting frame 2 in a mirror image, and the two rings 21 are arranged coaxially in a vertical state, and an annular slide groove 211 is arranged on the opposite sides of the two rings 21; there are two groups of shape-adjusting mechanisms 3, and the shape-adjusting mechanisms 3 are arranged on corresponding rings 21; each group of shape-adjusting mechanisms 3 comprises a plurality of rectangular positioning frames 31 slidably arranged in corresponding annular slide grooves 211; a square bar 32 is slidably arranged in each rectangular positioning frame 31, and an L-shaped adjusting plate 33 is arranged at one end of each square bar 32 close to the axis of the corresponding ring 21, and a rotating wheel 34 is rotatably arranged on each L-shaped adjusting plate 33, and a plurality of rotating wheels 34 located on the same ring 21 are connected by a synchronous belt 35 for transmission; the fixing mechanism 5 There are two groups of fixing mechanisms 4, which are mirror-imaged on the workbench 1 and located on both sides of the mounting frame 2; the fixing mechanism 4 is used to fix the prefabricated long member to be welded; two mounting plates 36 are also arranged between the two synchronous belts 35, and the two mounting plates 36 are symmetrically arranged relative to the axis of the ring 21, and the two ends of the mounting plates 36 are respectively arranged on the corresponding synchronous belts 35, and there are two groups of welding mechanisms 5, which are arranged on the corresponding mounting plates 36 and can weld the prefabricated long member along the moving trajectory of the synchronous belt 35; each group of welding mechanisms 5 includes a first hydraulic rod 51, an elastic telescopic rod 52 and a horizontal plate 53; the first hydraulic rod 51 is arranged on the corresponding mounting plate 36, the actuator of the first hydraulic rod 51 passes through the mounting plate 36 and is provided with an elastic telescopic rod 52, and each elastic telescopic rod 52 is provided with a horizontal plate 53 at one end away from the first hydraulic rod 51, and a welding gun 54 is arranged on the horizontal plate 53.

[0035] The staff places two prefabricated long members to be welded inside the two collars 21 respectively. At this time, the prefabricated long members to be welded are fixed by the fixing mechanism 4 arranged on the workbench 1, so that the corresponding ends of the two prefabricated long members to be welded can correspond to each other and be located between the two collars 21; the cross section of the prefabricated long members to be welded is a regular polygon, which can be a regular hexagon, a regular heptagon, etc.; in this embodiment, the cross section of the prefabricated long members to be welded is a regular hexagon (depending on the shape of the cross section). Figure 1As shown in the figure, according to the shape of the prefabricated long member to be welded in this embodiment, there are six rectangular positioning frames 31 on each collar 21, and a square bar 32 is slidably arranged in each rectangular positioning frame 31. The rotating wheels 34 on the six square bars 32 are connected by a synchronous belt 35. The staff adjusts the position of the rectangular positioning frame 31 so that the rectangular positioning frame 31 can be moved to the corresponding corner of the prefabricated long member to be welded, and then adjusts the square bar 32 in the rectangular positioning frame 31, so that the synchronous belt 35 is kept in a taut state, and the shape of the synchronous belt 35 is the same as the cross-sectional shape of the prefabricated long member to be welded. Two mounting plates 36 are also arranged between the two synchronous belts 35, and the two mounting plates 36 are symmetrically arranged relative to the axis of the collar 21. The actuator of the welding gun 54 (and the welding part of the welding gun 54) passes through the horizontal plate 53 and faces the direction of the prefabricated long member. By adjusting the first hydraulic rod 51, the welding gun 5 4 can contact with the contact ends of the two prefabricated long members to be welded; a servo motor for driving the rotating wheel 34 to rotate is arranged on one of the L-shaped adjustment plates 33 located on the same sleeve ring 21. As the two servo motors rotate, the two synchronous belts 35 rotate synchronously, so that the welding gun 54 can weld the contact ends of the two prefabricated long members to be welded along the shape of the synchronous belt 35 as the synchronous belt 35 moves. Under the action of the elastic telescopic rod 52, not only can the welding gun 54 be prevented from having a rigid collision with the prefabricated long member to be welded, but the welding gun 54 can also always fit the prefabricated long member to be welded, thereby ensuring the continuity of welding; by providing two welding guns 54, the welding time can be reduced and the welding efficiency can be improved; and during the welding process, the welding gun 54 is in a moving state, and the two prefabricated long members to be welded are in a stationary state, thereby ensuring the consistency of the weld and improving the welding quality of the welding gun 54.

[0036] It is particularly noted that the facing sides in the present application are the sides that are close to each other.

[0037] See also Figure 8 As shown, each rectangular positioning frame 31 is further provided with a vertical plate 311 on one side close to the corresponding collar 21, a threaded hole 312 is provided on the vertical plate 311, a threaded rod 313 is threadedly connected to the threaded hole 312, each square bar 32 is provided with a strip avoidance groove 321 for avoiding the threaded rod 313, an annular groove 314 is provided at one end of each threaded rod 313 away from the vertical plate 311, a clamping plate 315 is rotatably provided in each annular groove 314, a clamping block 316 is provided at one end of each clamping plate 315 away from the annular groove 314, and an annular clamping groove 212 cooperating with the clamping block 316 is provided on the away sides of the two collars 21.

[0038] The staff moves the corresponding number of rectangular positioning frames 31 to the corresponding positions of the collar 21 according to the shape of the prefabricated long component to be welded, and then rotates the threaded rod 313, which is threadedly connected to the threaded hole 312 on the vertical plate 311. As the threaded rod 313 rotates, the clamping plate 315 set on the threaded rod 313 can be moved toward the annular groove 212 close to the corresponding collar 21. Each square bar 32 is provided with a strip avoidance groove 321 for avoiding the threaded rod 313, thereby avoiding the volume collision between the threaded rod 313 and the square bar 32, so that the clamping block 316 on the clamping plate 315 can conflict with the annular groove 212 on the corresponding collar 21, thereby limiting the position of the rectangular positioning frame 31, thereby improving the stability of the movement of the welding gun 54 during welding.

[0039] It is particularly noted that the diverging side in the present application refers to a side that is away from each other.

[0040] See also Figure 8 and Fig. 9 As shown, each square bar 32 is provided with a strip-shaped groove 322, and the strip-shaped groove 322 is connected with the corresponding strip-shaped avoidance groove 321. A rotating hole 317 is provided on the side of each rectangular positioning frame 31 away from the corresponding sleeve 21. A rotating shaft 318 is rotatably provided in the rotating hole 317, and an adjusting gear 3181 is provided at one end of the rotating shaft 318 extending into the strip-shaped groove 322. A plurality of first gear teeth 323 are provided on the inner wall at the bottom of each strip-shaped groove 322 along the length direction, and the first gear teeth 323 are meshed with the corresponding strip gear.

[0041] When the rectangular positioning frame 31 moves to the corresponding position, by adjusting the rotating shaft 318, as the rotating shaft 318 rotates, the adjusting gear 3181 set at the end of the rotating shaft 318 and the first gear tooth 323 in the strip-shaped groove 322 engage with each other, so that the corresponding square bar 32 can move in the direction away from the axis of the corresponding ring 21, so that the corresponding synchronous belt 35 can be in a taut state, ensuring the stability of the movement of the welding gun 54.

[0042] See also Figures 4 to 6As shown, a synchronization mechanism 6 for making multiple rotating shafts 318 on two sleeve rings 21 rotate synchronously is arranged on the mounting frame 2; the synchronization mechanism 6 includes an inner gear ring 61 and a drive shaft 62; there are two inner gear rings 61, and the two inner gear rings 61 are rotatably arranged on the mounting frame 2 in a vertical state, and the two inner gear rings 61 are connected to each other through a reinforcing column 611; the drive shaft 62 is rotatably arranged on the mounting frame 2 in a horizontal state, and two driving gears 621 are equidistantly arranged on the drive shaft 62, and the outer wall of each inner gear ring 61 is provided with a plurality of tooth grooves 612 along the axial direction, and the driving gear 621 is meshed with the corresponding tooth grooves 612, and a driving motor 63 for rotating the driving shaft 62 is also arranged on the mounting frame 2; each rotating shaft 318 is away from the adjusting gear A guide groove 3182 is mirrored on the outer wall of one end of the wheel 3181, and a synchronizer ring 3183 is slidably arranged on each rotating shaft 318. A plurality of second gear teeth 3184 cooperating with the inner gear ring 61 are arranged on the outer wall of the synchronizer ring 3183 along the axial direction, and a guide block 3185 cooperating with the guide groove 3182 is mirrored on the inner wall of the synchronizer ring 3183. The guide block 3185 can be slidably arranged in the corresponding guide groove 3182. A threaded portion 3186 is also provided on the end of each rotating shaft 318 away from the adjusting gear 3181, and a sleeve 3187 is threadedly connected to the threaded portion 3186. A separation spring 3188 is also sleeved on each rotating shaft 318, and the separation spring 3188 is located between the corresponding rectangular positioning frame 31 and the synchronizer ring 3183.

[0043] Before welding is performed, the separation spring 3188 generates an elastic force, thereby enabling the synchronizer ring 3183 to move toward the direction close to the threaded portion 3186. The setting of the threaded portion 3186 can prevent the synchronizer ring 3183 from being pushed out of the rotating shaft 318 due to the elastic force of the separation spring 3188. At this time, the second gear teeth 3184 on the outer wall of the synchronizer ring 3183 are separated from the corresponding inner gear ring 61, thereby preventing the synchronizer ring 3183 from meshing with the inner gear ring 61 during the movement of the rectangular positioning frame 31, resulting in a change in the position of the square bar 32.

[0044] When welding is required, the staff adjusts the position of the rectangular positioning frame 31. After the position of the rectangular positioning frame 31 is fixed, the sleeve 3187 is adjusted. With the cooperation of the threaded portion 3186, the sleeve 3187 moves toward the direction close to the synchronous ring 3183. In this process, the synchronous ring 3183 overcomes the elastic force of the corresponding separation spring 3188 and moves toward the direction close to the corresponding rectangular positioning frame 31, so that the second gear teeth 3184 on the outer wall of the synchronous ring 3183 can mesh with the corresponding inner gear ring 61. As the drive motor 63 drives, the drive shaft 62 rotates, and the drive shaft 62 meshes with the tooth grooves 612 of the corresponding inner gear ring 61 through two drive gears 621, so that the two inner gear rings 61 can rotate synchronously, thereby ensuring that the shapes of the two synchronous belts 35 are the same, ensuring the stability of the movement of the welding gun 54, and improving the welding quality.

[0045] See also Figure 6 and Figure 7 As shown, two extension bars 531 are provided on one side of each horizontal plate 53 away from the elastic telescopic rod 52 . The two extension bars 531 are located on both sides of the corresponding welding gun 54 . A positioning wheel 532 is rotatably provided on one end of each extension bar 531 away from the horizontal plate 53 .

[0046] During the welding process of the welding gun 54, the positioning wheel 532 arranged on the extension bar 531 can contact the two prefabricated long members to be welded respectively, which can not only further avoid the rigid collision between the welding gun 54 and the prefabricated long members to be welded, but also make the movement of the welding gun 54 more stable, thereby improving the welding effect; and an elastic and high-temperature resistant friction sleeve is also arranged on the outer wall of the positioning wheel 532. With the driving of the first hydraulic rod 51, the friction sleeve can be squeezed, and under the elastic force of the elastic telescopic rod 52, the welding gun 54 can always fit the contact ends of the two prefabricated long members to be welded during the movement, thereby ensuring the overall welding quality. And the extension bar 531 can block a certain amount of sparks during the welding process, thereby ensuring the safety of the staff.

[0047] See also Figure 1 and Figure 3 As shown, the fixing mechanism 4 includes an arc-shaped fixing frame 41, a positioning ring 42 and a second hydraulic rod 43; the arc-shaped fixing frame 41 is arranged on the workbench 1, the positioning ring 42 is fixedly arranged on the arc-shaped fixing frame 41, and a plurality of second hydraulic rods 43 are radially arranged on the inner wall of the positioning ring 42 along the axial direction, and each second hydraulic rod 43 is hinged with a fitting plate 44 at one end facing the axis of the positioning ring 42.

[0048] By providing a plurality of second hydraulic rods 43, the staff places the prefabricated long member to be welded inside the corresponding positioning ring 42. Subsequently, by adjusting the plurality of second hydraulic rods 43, the plurality of second hydraulic rods 43 can be synchronously moved toward the direction close to the prefabricated long member to be welded, and the fitting plate 44 hinged at the end of the second hydraulic rod 43 can be tightly attached to the outer wall of the prefabricated long member to be welded, thereby fixing the prefabricated long member to be welded and ensuring the stability of the prefabricated long member to be welded during the welding process.

[0049] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
