Description

Technical Field

[0001] The invention relates to the technical field of welding devices, and in particular to a welding device for steel structure construction used in assembled buildings. Background Art

[0002] Prefabricated steel structure refers to the prefabricated building components whose structural system is composed of steel (components). It has been widely promoted due to its advantages of fast construction speed, excellent seismic performance, light weight, green environmental protection and good economy. During the construction process of prefabricated steel structure, welding equipment is required to connect them.

[0003] The existing welding devices for steel structure construction of prefabricated buildings are usually composed of a base that can move freely in space and a clamping mechanism. The clamping mechanism clamps the welding rod and provides welding current to the welding rod to melt it and then connect the steel structure. When multiple groups of steel structures are operated continuously, the welding rod needs to be replaced multiple times. However, due to the lack of a method for containing and replacing the welding rod, the existing welding device usually needs to be moved to a workstation by a mobile device to replace the welding rod after use, and then moved to a welding station for welding. This operation method has poor continuity and reduces the efficiency of welding. At the same time, since secondary positioning is required during the welding process, it is easy to cause welding deviation, which reduces the quality of welding. Summary of the invention

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: during the forward and backward movement of the driving mechanism, the clamping mechanism switches between unlocking and locking states. In the unlocking state, the used welding rod is detached from the clamping mechanism. In the locked state, the clamping mechanism clamps the welding rod to perform welding operations. At the same time, the driving mechanism drives the feeding mechanism to move the welding rod to the clamping mechanism for clamping and fixing, thereby realizing automatic replacement of the welding rod, avoiding the time for the supporting base to move due to the need to replace the welding rod during the welding process, and at the same time, reducing the time-consuming subsequent adjustment of the welding position, maintaining the continuity of welding, and improving the welding efficiency while improving the welding quality. Specifically: The rear push rod drives the connecting rack to slide to the left, and the connecting rack drives the driving rack to move to the right through the matching gear meshing with it, and the driving slide block slides to the right along the connecting frame, and the sliding column slides along the driving slide groove, and the connecting frame moves to the left. Under the cooperation of the driving spring, the driving slide block slides to the left along the connecting frame, and the clamping mechanism gradually switches from the unlocking state to the locking state, realizing the clamping limit of the new welding rod, which is convenient for welding operation. The state of the clamping mechanism is conveniently switched through the linkage action, thereby realizing the release of the used welding rod and the replacement of the new welding rod. The structure is simple, the setting of the power components is reduced, and the maintenance cost of the device of the present invention is reduced. 2. The driving slide block moves to the right, and the driving sleeve drives the driving slide bar to slide along the positioning inclined groove, the two-way rotating column rotates, and the two-way rotating column drives the positioning slide groove to rotate synchronously. The positioning slide groove drives the positioning wedge-shaped tooth to rotate through the positioning slide block that slides with it, and the positioning wedge-shaped tooth rotates and drives the material-diverting rotating column to rotate through the material-diverting slide groove. The material-diverting roller rotates, and the new welding rod in the insulation box moves downward out of the insulation box. After that, the driving slide block moves to the left, and the two-way rotating column drives the positioning slide groove to rotate synchronously in the opposite direction. The positioning slide groove drives the positioning wedge-shaped tooth to rotate in the opposite direction through the positioning slide block that slides with it, and the positioning wedge-shaped tooth slides along the material-diverting slide groove without driving the material-diverting rotating column to rotate. The driving slide block only drives one welding rod to move out of the insulation box for pre-loading in one stroke, thereby avoiding blockage caused by the synchronous movement of multiple welding rods, ensuring smooth loading, and improving the stability of the operation of the device of the present invention. 3. The clamping mechanism drives the adjusting top block to move toward the driving wedge block by rotating the adjusting screw, so that the clamping arm can be rotated more widely while the driving wedge block moves the same distance toward the clamping arm, thereby increasing the clamping force and conveniently adjusting the clamping force of the clamping mechanism to avoid slippage or falling off of the welding rod during use, thereby ensuring the continuity of welding, increasing the welding speed and improving the welding quality.

DETAILED DESCRIPTION

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0026] Combined with Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 5 With attached Figure 7As shown, a welding device for steel structure construction of assembled buildings includes a supporting base 1, a driving wheel is rotatably provided at the lower end of the supporting base 1, a clamping mechanism 15 for clamping welding rods is provided on the supporting base 1, a storage mechanism 2 for storing welding rods is provided on the supporting base 1, the storage mechanism 2 can move freely in space, a feeding mechanism 3 for pushing welding rods from the storage mechanism 2 to the clamping mechanism 15 is provided at the lower end of the storage mechanism 2, a connecting frame 14 is provided at one end of the storage mechanism 2, and a driving mechanism for driving the feeding mechanism 3 to operate after the welding rods are used is provided on the connecting frame 14 4. The supporting base 1 is an L-shaped structure, a lifting plate 11 is slidably provided on the supporting base 1, a bearing plate 12 is slidably provided on the lifting plate 11, a supporting plate 13 connected to the storage mechanism 2 is slidably provided on the bearing plate 12, and the moving directions of the bearing plate 12 and the supporting plate 13 are perpendicular to each other, a lifting electric push rod 16 for driving the lifting plate 11 to move up and down is provided on the supporting base 1, a bearing electric push rod 17 for driving the bearing plate 12 to move forward and backward is provided on the lifting plate 11, and a supporting electric push rod 18 for driving the supporting plate 13 to move left and right is provided on the bearing plate 12.

[0027] The working principle of the present invention is as follows: the lifting electric push rod 16 can drive the lifting plate 11 to move up and down, the load-bearing electric push rod 17 can drive the load-bearing plate 12 to move forward and backward, and the supporting electric push rod 18 can drive the supporting plate 13 to move left and right, thereby driving the supporting plate 13 to move freely in the up and down, front and back, and left and right directions, which is convenient for welding operations on steel structures. Furthermore, the supporting plate 13 drives the connecting frame 14 to move synchronously during the movement process, and the connecting frame 14 drives the welding rod to move through the clamping mechanism 15 to weld the steel structure. During the process of the connecting frame 14 driving the driving mechanism 4 to move forward and backward, the driving mechanism 4 switches the clamping mechanism 15 between the unlocking state and the locking state. In the unlocking state, the clamping mechanism The structure 15 loses its grip on the used welding rod, and the used welding rod is detached from the clamping mechanism 15. In the locked state, the clamping mechanism 15 clamps the welding rod, thereby performing welding operations. At the same time, the driving mechanism 4 drives the feeding mechanism 3 to perform reciprocating linear motion during the movement process, and the feeding mechanism 3 moves the welding rod to the clamping mechanism 15 for clamping and fixing, thereby realizing automatic replacement of the welding rod, avoiding the time for the supporting base 1 to move due to the need to replace the welding rod during the welding process. At the same time, since the welding rod can be replaced without moving, the time-consuming subsequent adjustment of the welding position is reduced, the continuity of welding is maintained, and the welding efficiency is improved while improving the welding quality.

[0028] Combined with Figure 2 , Attachment Figure 3 With attached Figure 4As shown, the driving mechanism 4 includes a driving slider 41 slidably arranged on the inner side of the connecting frame 14, the driving slider 41 is provided with a driving spring 413 connected to the connecting frame 14, the driving slider 41 is provided with a driving slide 411, and the driving slide 411 is a heart-shaped structure, the connecting frame 14 is provided with a connecting column 141, and a rotating arm 42 is rotatably arranged on the connecting column 141, and a sliding column 421 slidably matched with the driving slide 411 is slidably arranged at one end of the rotating arm 42, and a sliding column 421 is sleeved with a rotating arm 42 The sliding spring 422 is connected, and the driving slide groove 411 has ups and downs. The driving slide groove 411 makes the sliding column 421 slide unidirectionally along the driving slide groove 411 through the height change. A front push rod 412 is provided at one end of the driving slider 41, and a driving rack 414 is provided on one side of the driving slider 41. A matching rotating column 43 is rotatably provided on one side of the connecting frame 14. A matching gear 431 meshing with the driving rack 414 is provided on the matching rotating column 43, and a matching bevel gear 432 matching with the feeding mechanism 3 is provided on the matching gear 431; A connecting slot 142 is provided on one side of the connecting frame 14, a connecting slider 143 is slidably provided in the connecting slot 142, a connecting rack 144 meshing with the matching gear 431 is provided on the connecting slider 143, and a rear push rod 145 matching with the supporting base 1 is provided on the connecting rack 144.

[0029] The working principle of the driving mechanism 4 is as follows: when the connecting frame 14 moves to the left, the connecting frame 14 drives the driving slider 41 to move to the left synchronously until the front push rod 412 contacts the steel structure. At this time, the welding rod is about to be used up. After that, the connecting frame 14 continues to move to the left until the welding rod is used up. The steel structure reacts on the front push rod 412, and the front push rod 412 drives the driving slider 41 to slide to the right along the connecting frame 14. The clamping mechanism 15 gradually switches from the locked state to the unlocked state, and the used welding rod falls off the clamping mechanism 15. During this process, the sliding column 421 slides along the driving slide groove 411, and the rotating arm 42 rotates counterclockwise. After that, the connecting frame 14 is controlled to move to the right to make the rotating arm 42 rotate clockwise to the position as shown in the attached figure. Figure 3 In the state shown, the feeding mechanism 3 pushes the new welding rod to cooperate with the clamping mechanism 15 in cooperation with the rotation of the bevel gear 432; Afterwards, the connecting frame 14 continues to move to the right, and the connecting frame 14 drives the driving slide block 41 to move to the right synchronously until the rear push rod 145 contacts the supporting base 1. The supporting base 1 reacts on the rear push rod 145, and the rear push rod 145 drives the connecting rack 144 to slide to the left. The connecting rack 144 drives the driving rack 414 to move to the right through the matching gear 431 meshing with it, and the driving slide block 41 slides to the right along the connecting frame 14, and the sliding column 421 slides along the driving slide groove 411. The rotating arm 42 rotates clockwise, and the sliding column 421 loses the limit on the driving slide block 41. At this time, the connecting frame 14 moves to the left, and with the cooperation of the driving spring 413, the driving slide block 41 slides to the left along the connecting frame 14, and the clamping mechanism 15 gradually switches from the unlocked state to the locked state, realizing the clamping limit of the new welding rod, which is convenient for welding operations. In this process, the bevel gear 432 rotates, and the feeding mechanism 3 is reset to prepare for the subsequent movement to push the welding rod.

[0030] Combined with Figure 2 , Attachment Figure 4 , Attachment Figure 5 With attached Figure 6 As shown, the clamping mechanism 15 includes a clamping arm 151 symmetrically rotatably arranged on the connecting frame 14, the clamping arm 151 is an L-shaped structure, a clamping groove 1511 is provided at the lower end of the clamping arm 151, an adjusting screw 152 is threadedly connected to the clamping arm 151, an adjusting top block 1521 is provided at the lower end of the adjusting screw 152, two groups of the clamping arms 151 are rotatably provided with a clamping rotating block 153, a clamping spring 154 is provided between the two groups of the clamping rotating blocks 153, a driving column 44 is provided at the lower end of the driving slider 41, and a driving wedge block 441 that slidably cooperates with the adjusting top block 1521 is provided at the lower end of the driving column 44.

[0031] The working principle of the clamping mechanism 15 is as follows: when the driving slider 41 moves toward the direction approaching the clamping arm 151, the driving slider 41 drives the driving wedge block 441 to move synchronously through the driving column 44, the driving wedge block 441 slides with the adjusting top block 1521, the driving wedge block 441 drives the clamping arm 151 to rotate synchronously through the adjusting top block 1521, the two groups of clamping grooves 1511 approach each other to clamp and fix the welding rod, the clamping arm 151 pulls the clamping spring 154 through the clamping rotating block 153, and the clamping spring 154 stretches. On the contrary, when the driving slider 41 moves away from the clamping arm 151, the driving slider 41 drives the driving wedge block 441 to move synchronously through the driving column 44, the clamping spring 154 resets and drives the clamping arm 151 to rotate synchronously through the clamping rotating block 153, the two groups of clamping grooves 1511 move away from each other, the used welding rod falls off the clamping groove 1511, and it is convenient to clamp the new welding rod. Furthermore, the adjusting screw 152 is rotated, and the adjusting screw 152 drives the adjusting top block 1521 to move toward the driving wedge block 441. When the driving slider 41 drives the driving wedge block 441 to move the same distance toward the clamping arm 151 through the driving column 44, the driving wedge block 441 drives the clamping arm 151 to rotate more through the adjusting top block 1521 and the adjusting screw 152, and the clamping groove 151 is narrowed, thereby increasing the clamping force.
