DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] It can be understood that the terms "first", "second", etc. used in the present application can be used in this article to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish the first element from another element.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 and Fig.11 As shown, in one embodiment, a welding device for light steel structure processing is proposed, the device includes four stations: a loading station a, a locking station b, a docking station c and a resetting station d, and also includes:

[0039] The main frame 1 includes a mounting platform 101 disposed on the main frame 1;

[0040] Support device 2: includes four moving frames 201 installed on the mounting platform 101 for supporting the light steel, the contact surface between the moving frame 201 and the light steel is set as a smooth surface, and also includes four positioning frames 202 installed on the mounting platform 101 for limiting one end of the light steel, and a plurality of wiping wool wheels 203 in contact with one end of the light steel are fixedly installed on the surface of each positioning frame 202;

[0041] Tilt mechanism 3: Tilt and position the light steel by cooperating with the slide mechanism 4;

[0042] Contraction mechanism 5: releases the limit on the light steel welding end by cooperating with the tooth mechanism 6;

[0043] Driving mechanism 7: used to drive the light steel to revolve;

[0044] Thrust mechanism 8: used to drive two light steels to dock.

[0045] In actual application of the embodiment of the present invention, when welding light steel, the light steel is placed on the moving frame 201 by external feeding equipment, such as Figure 1 As shown, due to the action of the tilting mechanism 3 and the chute mechanism 4, the moving frame 201 at the loading station a is in an inclined state, so the light steel placed on the moving frame 201 slides obliquely downward along the moving frame 201 under the action of gravity, and the light steel at the end of the moving frame 201 is limitedly supported by the positioning frame 202, as shown in FIG. Fig.11 As shown, at this time, the position of the light steel is fixed under the action of the thrust mechanism 8, so that the welding end of light steels of different lengths can be accurately positioned, and the driving action of the driving mechanism 7 drives the moving frame 201 to revolve through the tilting mechanism 3. When it moves from the loading station a to the locking station b, as shown in FIG. Figure 3 and Figure 5 As shown, at this time, the cooperation of the tilting mechanism 3 and the sliding groove mechanism 4 makes the moving frame 201 no longer in a tilted state, and the moving frame 201 and the moving frame 201 at its symmetrical end are located in a straight line. When the moving frame 201 moves from the locking position b to the docking position c under the driving action of the driving mechanism 7, as shown in FIG. Figure 8 As shown, from Figure 8 From the front view direction, at this time, under the action of the retracting mechanism 5 and the tooth mechanism 6, the positioning frame 202 first moves downward and then moves to the left. In the process of the positioning frame 202 moving downward, the wiping wheel 203 contacts and wipes the end face of the welding end of the light steel, thereby preventing the stains on the end face of the welding end of the light steel from affecting the quality of welding. When the positioning frame 202 moves to the left, the welding end of the light steel is no longer blocked by the positioning frame 202. At the docking station c, the moving frame 201 is extended by the action of the thrust mechanism 8, so that the welding end face of the light steel on the moving frame 201 is butted against the welding end face of the light steel on the symmetrical end moving frame 201. At this time, the welding device Prepare to weld two light steels. After welding, the light steel is released by the thrust mechanism 8, so that the welded light steel falls on the receiving equipment below, thereby achieving the purpose of automatic welding and unloading. At this time, under the driving action of the driving mechanism 7, it moves from the docking station c to the reset station d, so that the shrinking mechanism 5 is reset, and then the positioning frame 202 is reset, and then the driving mechanism 7 moves from the reset station d to the loading station a, so that the tilting mechanism 3 is reset, and the tilting loading is performed at the loading station a, thereby achieving rapid cycle loading, and the purpose of precise end face positioning welding can be completed for light steels of different lengths.

[0046] like Figure 3 and Fig.11 As shown, as a preferred embodiment of the present invention, the tilting mechanism 3 includes two symmetrical circulation disks 305 fixedly mounted on the driving mechanism 7, and the inner wall of each circulation disk 305 is rotatably connected to eight rotating columns 304, and also includes eight support frames 301 installed on the mounting table 101, and the surface of each support frame 301 is fixedly mounted with two rotating columns 304, and the inner wall of the support frame 301 is slidably mounted with a moving frame 201, and the surface of the support frame 301 is in contact with the positioning frame 202, and the surface of each support frame 301 is slidably mounted with a moving slider 302, and the surface of the moving slider 302 is rotatably mounted with a thrust rod 303.

[0047] In practical application, when the embodiment of the present invention is at the loading station a, as shown in FIG. Figure 3 As shown, through the support of the slide mechanism 4, the thrust rod 303 lifts one end of the support frame 301 by moving the slider 302, as shown in FIG. Fig.11As shown, the support frame 301 is rotated on the circulation disk 305 through the rotating column 304. At this time, the support frame 301 is in an inclined state, which makes the moving frame 201 also in an inclined state. When moving from the loading station a to the locking station b, the thrust rod 303 is moved toward the central axis of the circulation disk 305 under the action of the slide mechanism 4, and then the rotating column 304 is rotated on the circulation disk 305 to make one end of the support frame 301 drop. When moving to the locking station b, the support frame 30 1 is located on the same straight line as the support frame 301 at its symmetrical end. When moving from the locking station b to the reset station d, the thrust rod 303 will not move under the action of the slide mechanism 4. When moving from the reset station d to the feeding station a, the thrust rod 303 is driven by the slide mechanism 4 to move away from the central axis of the circulation disk 305, so that the support frame 301 starts to tilt again and is in a tilted state again at the feeding station a, thereby achieving the purpose of ensuring the precise positioning of the light steel welding end through tilted feeding.

[0048] like Figure 3 As shown, as another preferred embodiment of the present invention, the slide mechanism 4 includes a slide plate 401 fixedly mounted on the mounting table 101, and the interior of the slide plate 401 is provided with a descending slide 402, a concentric slide 403 and an ascending slide 404 which cooperate with the thrust rod 303 and are smoothly connected in sequence, the trajectory radius of the descending slide 402 gradually decreases, the trajectory radius of the concentric slide 403 is equal, and the trajectory radius of the ascending slide 404 gradually increases.

[0049] In practical application of the embodiment of the present invention, when moving from the loading station a to the locking station b, as shown in FIG. Figure 3 As shown, at this time, the support frame 301 moves from the inclined state to the state in the same straight line with the symmetrical end support frame 301 through the cooperation of the thrust rod 303 and the descending slide groove 402. When moving from the locking station b to the reset station d, the thrust rod 303 does not move through the cooperation of the thrust rod 303 and the concentric slide groove 403. When moving from the reset station d to the loading station a, the support frame 301 returns to the inclined state through the action of the ascending slide groove 404, thereby achieving the purpose of cyclically changing the posture of the support frame 301 and ensuring cyclic loading and welding.

[0050] like Figure 5 , Figure 6 , Figure 7 , Fig.10 , Fig.12 and Fig.13As shown, as another preferred embodiment of the present invention, the retracting mechanism 5 includes a rotating gear 501 installed on the support frame 301, and a rotating screw 502 is coaxially fixedly installed on the surface of the rotating gear 501. The rotating screw 502 passes through the support frame 301 and is rotatably connected to the support frame 301. The rotating screw 502 and the screw slider 503 form a spiral pair transmission, and the screw slider 503 is slidably connected to the surface of the support frame 301. A connecting cylinder 504 is fixedly installed on the surface of the screw slider 503, and a sliding groove rod 505 and a tension plate 509 are fixedly installed on the surface of the connecting cylinder 504. A linkage rotating cylinder 506 passes through the surface of the support frame 301 and is rotatably connected to the linkage rotating cylinder 506. The inner wall of the linkage rotating cylinder 506 is provided with a spiral groove 506 that cooperates with the sliding groove rod 505 and is smoothly connected in sequence. 07 and straight groove 508, a connecting rod 511 passes through the interior of the linkage rotating cylinder 506 and is slidably connected to the connecting rod 511, one end of the connecting rod 511 is fixedly installed with a force plate 510, the radius of the tension plate 509 is larger than the inner diameter of the force plate 510, the surface of the connecting rod 511 is connected to the surface of the linkage rotating cylinder 506 through a compression spring 512, the other end of the connecting rod 511 is set to an I-shape, and the other end of the connecting rod 511 is slidably connected to the U-groove rod 513, the surface of the U-groove rod 513 is fixedly installed with an L-shaped plate 514, the L-shaped plate 514 is slidably connected to the inner wall of the sliding block 515, two connecting plates 516 are fixedly installed on the surface of the support frame 301, each connecting plate 516 is slidably connected to the sliding block 515, and the other end of the L-shaped plate 514 is fixedly connected to the surface of the positioning frame 202.

[0051] In practical application, the embodiment of the present invention is as follows: Fig.13 As shown, when moving from the locking position b to the docking position c, the gear mechanism 6 drives the rotating gear 501 to rotate, as shown in FIG. Figure 5 As shown, the rotation of the rotating gear 501 drives the rotating screw 502 to rotate synchronously, as shown in FIG. Figure 6 As shown, the screw slider 503 is driven to move to the left through the transmission action of the spiral pair. The leftward movement of the screw slider 503 first drives the linkage drum 506 to rotate through the cooperation of the slide rod 505 and the spiral groove 507. At this time, the rotation of the linkage drum 506 drives the connecting rod 511 to revolve. Figure 7As shown, at this time, the rotation of the connecting rod 511 drives the U-groove rod 513 to move downward through the sliding connection with the U-groove rod 513, and then drives the positioning frame 202 to move downward through the L-shaped plate 514. At the same time, the sliding block 515 slides downward along the connecting plate 516. The downward movement of the positioning frame 202 drives the wiping wheel 203 to wipe the welding end surface of the light steel, thereby preventing the stains on the welding end surface from affecting the welding quality. As the sliding groove rod 505 moves to the straight groove 508, the leftward movement of the connecting cylinder 504 no longer drives the linkage rotating cylinder 506 to rotate, and the tension plate 509 pulls the force plate 509 to rotate. 10 moves synchronously to the left, thereby pulling the connecting rod 511 to move to the left. The leftward movement of the connecting rod 511 drives the L-shaped plate 514 to move to the left through the U-slot rod 513, thereby driving the positioning frame 202 to move to the left, avoiding interference when the light steel is subsequently butted, increasing the operating space for light steel end face welding, thereby improving the efficiency of light steel welding. When the welding is completed and the material moves from the butt joint station c to the reset station d, the rotating gear 501 is caused to rotate in the reverse direction through the action of the tooth mechanism 6, and the reverse rotation of the rotating gear 501 drives the positioning frame 202 to reset, thereby facilitating the subsequent cyclic welding.

[0053] In practical application of the embodiment of the present invention, when moving from the locking station b to the docking station c, as shown in FIG. Fig.13 As shown, at this time, the rotating gear 501 is meshed with the inner ring teeth 602, which drives the rotating gear 501 to rotate, and then drives the positioning frame 202 to move downward first and then to the left through the contraction mechanism 5, so as to weld the light steel. When the welding is completed and moves from the docking station c to the reset station d, the rotating gear 501 is meshed with the outer ring teeth 603 to drive the rotating gear 501 to reverse, and then drives the positioning frame 202 to reset, so as to perform cyclic loading and welding.

[0054] like Fig. 9 As shown, as another preferred embodiment of the present invention, the driving mechanism 7 includes a driving motor 701 fixedly mounted on the surface of the slide plate 401, and a rotating main shaft 702 is fixedly mounted on the output end of the driving motor 701. The rotating main shaft 702 passes through the slide plate 401 and is rotatably connected to the slide plate 401, and two symmetrical circulating disks 305 are coaxially fixedly mounted on the surface of the rotating main shaft 702.

[0055] When the embodiment of the present invention is actually applied, when performing welding operations on light steel, the operation of the driving motor 701 drives the rotating spindle 702 to rotate, and the rotation of the rotating spindle 702 drives the circulating disk 305 to rotate, thereby performing cyclic welding operations at the four stations of loading station a, locking station b, docking station c and resetting station d.

[0057] In practical application of the embodiment of the present invention, when the light steel loading operation is completed at the loading station a, as shown in FIG. Fig.11 As shown, at this time, the light steel is fixed by the locker 804, and when it moves to the docking station c, as shown in FIG. Figure 5 As shown, from Figure 5 Looking from the front direction, the thrust motor 801 starts to run at this time, and the operation of the thrust motor 801 drives the thrust screw 802 to rotate, and then drives the thrust slider 803 to move to the right through the spiral pair transmission, and then drives the movable frame 201 to move to the right. At this time, the light steel symmetrically fixed at both ends of the docking station c is docked, and then the welding operation is completed. When the welding is completed, the locker 804 is operated to release the welded light steel, thereby achieving the purpose of automatic unloading. At the same time, the thrust motor 801 runs in the reverse direction to reset, which is convenient for the cyclic welding operation.
