Description

Technical Field

[0001] The utility model relates to the technical field of welding tooling, in particular to an automatic clamping welding tooling for a cross beam of an elevator base. Background Art

[0002] The elevator machine base is also called the elevator traction machine base. The elevator machine base is fixedly connected to the top of the elevator manned box. A crossbeam is provided between the elevator machine base and the elevator manned box. The crossbeam connects the elevator machine base and the elevator manned box. The crossbeam is usually composed of channel steel and multiple reinforcing plates fixedly connected to the inner side of the channel steel. Therefore, the crossbeam needs to be welded with the channel steel and the reinforcing plate during production. At present, when welding the channel steel and the reinforcing plate of the crossbeam, the reinforcing plates are usually manually placed on the inner side of the channel steel in sequence, and the reinforcing plates placed on the inner side of the channel steel are manually supported and welded. In this way, the handheld welding of the reinforcing plate not only makes the welding of the reinforcing plate not simple and convenient, but also the manual support of the reinforcing plate is prone to tilting of the reinforcing plate. The welding of the tilted reinforcing plate and the channel steel will make the welding quality of the reinforcing plate poor.

[0023] like Figure 2As shown, the clamping mechanism 5 includes a slide bar 501, which is connected to a side wall of the fixed horizontal plate 4. The outer wall of the slide bar 501 is sleeved with a plurality of sliding blocks 502 in sequence. A first connecting plate 503 is fixedly connected to a side wall of the sliding blocks 502. The upper end surface of the first connecting plate 503 is rotatably connected to a second connecting plate 504. A fixed vertical plate 505 is fixedly connected to a side wall of the first connecting plate 503. A connecting spring 506 is provided between the fixed vertical plate 505 and the second connecting plate 504. The two ends of the connecting spring 506 are respectively fixedly connected to a side wall of the fixed vertical plate 505 and the second connecting plate 504 by bolts. A clamping plate 507 is fixedly connected to the lower end surface of the second connecting plate 504. The plurality of clamping plates 507 correspond to the positions of the plurality of reinforcing plates 9 on the inner side of the channel steel 8. The left and right side walls of the clamping plates 507 are provided with magnet mounting slots 508. When it is necessary to weld the reinforcing plate 9 on the inner side of the channel steel 8 to the channel steel 8, first install magnets in the magnet installation slots 508 on the left and right walls of the clamping plate 507, then hold one end of the second connecting plate 504, and then press the second connecting plate 504 downward toward the reinforcing plate 9. The second connecting plate 504 is forced to rotate along the top of the first connecting plate 503, and the rotation of the second connecting plate 504 drives the clamping plate 507 to rotate until the bottom end of the clamping plate 507 is located on the reinforcing plate 9 on the inner side of the channel steel 8. The top of the clamping plate 507, the reinforcing plate 9 on the lower end face of the clamping plate 507 is in an upright state under the adsorption of the magnet on its outer wall surface. After the position of the reinforcing plate 9 inside the channel steel 8 is fixed and stable, the reinforcing plate 9 and the channel steel 8 can be welded together by the welding device. If it is necessary to adjust the welding position of the reinforcing plate 9 inside the channel steel 8, the reinforcing plate 9 can be moved along the inner wall of the channel steel 8. After the reinforcing plate 9 is moved to the specified position, the clamping plate 507 is moved along the slide bar 501 until the position of the clamping plate 507 and the reinforcing plate 9 after the movement correspond to each other. The setting of the clamping mechanism 5 can replace the manual support of the reinforcing plate 9 that needs to be welded on the inner side of the channel steel 8, which not only makes the welding between the channel steel 8 and the reinforcing plate 9 simpler and more convenient, but also improves the welding quality of the reinforcing plate 9. The left and right positions of the clamping plate 507 can be moved to different spacings between multiple reinforcing plates 9 inside the channel steel 8.

[0024] like Figure 3As shown, multiple limiting devices 6 correspond to the positions of multiple second connecting plates 504 respectively, and the limiting devices 6 include a placing plate 601, and the lower end surface of the placing plate 601 is fixedly connected with a slider 602, and the slider 602 is slidably connected in the slide groove 10, and one side of the upper end surface of the placing plate 601 is fixedly connected with a support plate 607, and a groove is provided on one side wall of the support plate 607, and a connecting block 603 is rotatably connected to the inner side of the groove, and a threaded hole is provided at one end of the connecting block 603, and a threaded rod 604 is rotatably connected to the inner side of the threaded hole, and the end of the threaded rod 604 away from the connecting block 603 is fixedly connected to the limiting block 605, and a limiting groove 606 is provided on the upper end surface of the support plate 607. When the clamping plate 507 clamps the reinforcing plate 9 inside the channel steel 8, one end of the second connecting plate 504 is inserted into the limiting groove 606 on the upper end surface of the supporting plate 607, and then the limiting block 605 is rotated so that the limiting block 605 is located above the second connecting plate 504 inside the limiting groove 606, and then the limiting block 605 is rotated, and the rotation of the limiting block 605 drives the threaded rod 604 to rotate, and the rotation of the threaded rod 604 drives the limiting block 605 to move toward the second connecting plate 504 inside the limiting groove 606, until the lower end surface of the limiting block 605 is set on the upper end surface of the second connecting plate 504 inside the limiting groove 606. The second connecting plate 504 clamped above the reinforcing plate 9 can be positionally limited by the setting of the limiting device 6, so that the clamping plate 507 can continuously clamp the reinforcing plate 9 inside the channel steel 8, thereby saving manpower for clamping the reinforcing plate 9.

[0025] like Figure 4 As shown, two positioning devices 7 are respectively fixedly connected to the upper end surfaces of the placement plate 601 on both sides of the upper end surface of the supporting bottom plate 1, and the positioning device 7 includes a fixing seat 701, and a hand grip 702 is rotatably connected to one side of the upper end surface of the fixing seat 701, and a guide tube 703 is fixedly connected to the other side of the upper end surface of the fixing seat 701. A connecting piece 704 is rotatably connected to one side wall of the hand grip 702, and a positioning rod 705 is rotatably connected to one end of the connecting piece 704 away from the hand grip 702, and an end of the positioning rod 705 away from the connecting piece 704 passes through the guide tube 703 and is mounted on one side wall of the channel steel 8. When the channel steel 8 needs to be positionally restricted, the hand grip 702 is held by hand, and then the hand grip 702 is pushed toward the channel steel 8, and the hand grip 702 pushes the positioning rod 705 to move through the connecting piece 704 until one end of the positioning rod 705 is mounted on one side wall of the channel steel 8. The positioning device 7 can be provided to limit the position of the channel steel 8, so as to avoid the position shift of the channel steel 8 due to force during welding, thereby affecting the welding quality between the channel steel 8 and the reinforcing plate 9.

[0026] The working principle of the utility model is:

[0027] First, install magnets in the magnet mounting slots 508 on the left and right side walls of the clamping plate 507, then place the channel steel 8 on the upper end surfaces of the first fixed plate 2 and the second fixed plate 3, then hold the holding handle 702 by hand, and then push the holding handle 702 in the direction of the channel steel 8, and the holding handle 702 pushes the positioning rod 705 to move through the connecting piece 704 until one end of the positioning rod 705 is topped on one side wall of the channel steel 8, and then the reinforcing plate 9 is placed on the inner side of the channel steel 8 in sequence, and then hold one end of the second connecting plate 504 by hand, and then press the second connecting plate 504 downward in the direction of the reinforcing plate 9, and the second connecting plate 504 is forced to rotate along the top end of the first connecting plate 503, and the rotation of the second connecting plate 504 drives the clamping plate 507 to rotate until the bottom end of the clamping plate 507 is topped on the top end of the reinforcing plate 9 inside the channel steel 8, and the reinforcing plate 9 on the lower end surface of the clamping plate 507 is in an upright state under the adsorption of the magnet on its outer wall surface. When the welding position is reached, the reinforcing plate 9 can be moved along the inner wall of the channel steel 8. After the reinforcing plate 9 is moved to the specified position, the clamping plate 507 is moved along the slide bar 501 until the clamping plate 507 corresponds to the position of the reinforcing plate 9 after the movement. When the clamping plate 507 clamps the reinforcing plate 9 inside the channel steel 8, one end of the second connecting plate 504 is inserted into the limiting groove 606 on the upper end face of the supporting plate 607, and then the limiting block 605 is rotated so that the limiting block 605 is located at the inner side of the limiting groove 606. The limit block 605 is then rotated above the second connecting plate 504. The rotation of the limit block 605 drives the threaded rod 604 to rotate. The rotation of the threaded rod 604 drives the limit block 605 to move toward the second connecting plate 504 inside the limit groove 606, until the lower end surface of the limit block 605 is pressed against the upper end surface of the second connecting plate 504 inside the limit groove 606. After the position of the inner reinforcing plate 9 of the channel steel 8 is fixed and stabilized, the reinforcing plate 9 and the channel steel 8 can be welded together by a welding device.
