Description

Technical Field

[0001] The utility model relates to the technical field of welding tooling, in particular to a tooling piece which is convenient for coaxially welding a connecting shaft on a large box. Background Art

[0002] Currently, in Figure 1 When welding the connecting shaft to the large box shown, one end of the connecting shaft blank is generally inserted into the welding hole of the large box first, and then the two surfaces of the connecting shaft in contact with the box (the inner side and the outer side) are welded. When welding, it is necessary to ensure that the connecting shafts at both ends of the box are welded coaxially. Finally, the connecting shaft needs to be slotted, chrome-plated, polished, and other finishing operations.

[0033] Specifically, the box support mechanism 3 includes a support plate 301, which is fixedly connected to a non-slip rubber pad, and the bottom of the support plate 301 is fixedly connected to a first screw rod 302, and the interior of the base 2 is rotatably installed with an internal threaded tube 303 through a second seat bearing 308, and the lower end of the first screw rod 302 is threadedly rotatably connected to the interior of the internal threaded tube 303, and a worm gear 304 is fixedly sleeved on the internal threaded tube 303, and the interior of the base 2 is rotatably connected to a worm 305 through a first seat bearing 307, and the worm 305 is meshed with the worm gear 304, and one end of the worm 305 is rotated and arranged to pass through one side of the base 2, and the bottom of the support plate 301 is fixedly connected to a limiting rod 310, and a sliding sleeve 309 is fixedly connected to the base 2, and the lower end of the limiting rod 310 is slidably inserted into the sliding sleeve 309.

[0034] By setting up the box support mechanism 3, when in use, the box 1 is placed on the support plate 301, and the box 1 can be quickly positioned so that the center lines of the welding hole 101 and the positioning slot 402 are on the same straight line. By rotating the worm 305, the worm wheel 304 can be driven to rotate, and then the height position of the support plate 301 can be adjusted by the first screw 302 cooperating with the internal threaded tube 303.

[0035] Furthermore, the connecting shaft positioning mechanism 4 includes a support base 401, which is fixedly connected to the top of the base 2. To increase the support strength of the support base 401, a reinforcing rib 403 is fixedly welded between the side of the support base 401 and the base 2. The upper end of the support base 401 is provided with a positioning notch 402. The positioning notch 402 is arranged in a V shape, and the connecting shaft 102 contacts the inclined surfaces on both sides of the inner wall of the connecting shaft 102. Through this arrangement, the connecting shaft 102 can be quickly positioned in the positioning notch 402. To avoid scratching the surface of the connecting shaft 102, an arc block 6 is fixedly welded to the inclined surface of the inner wall of the positioning notch 402.

[0036] Furthermore, the connecting shaft fixing mechanism 5 includes a second screw rod 501 and a guide rod 502. The second screw rod 501 is rotatably connected to the base 2 through a third seat bearing. The guide rod 502 is fixedly welded to the top of the base 2.

[0037] The above design, through the setting of the connecting shaft fixing mechanism 5, when in use, by rotating the second screw 501, the pressure plate 504 can be driven downward by the moving block 503, so that the rounded surface at the bottom of the concave block is tightly against the upper surface of the connecting shaft 102, thereby fixing the connecting shaft 102 in the positioning slot 402.

[0038] For ease of operation, one end of the worm 305 away from the worm wheel 304 is fixedly connected to the first hand wheel 306 , and the top of the second screw rod 501 is fixedly connected to the second hand wheel 505 .

[0039] In order to position the flange 103 on the box body 1 to ensure that the four flanges 103 on the box body 1 can be welded symmetrically, especially the two flanges 103 on the same side are coaxially welded to ensure the welding quality of the flange 103, four groups of flange positioning mechanisms 7 are symmetrically arranged on the upper part of the support plate 301, and each group of flange positioning mechanisms 7 includes a guide rail 701 fixedly installed on the upper part of the support plate 301, and a positioning seat 703 slidably installed on the upper part of the guide rail 701 through a slider 702.

[0040] Specifically, in order to improve the welding stability of the flange 103 and the coaxiality between several flanges 103, a stop block can also be set on one side of the guide rail 701, and the stop block is fixed on the support plate 301. One end of the stop block is fixed and is used to block the positioning seat 703 and perform a sliding limit on the positioning seat 703. The other end of the stop block is movably provided with a rotating block. When the positioning seat 703 slides to the desired position, the positioning seat 703 is stuck by operating the rotating block to prevent it from shifting during the processing operation and affecting the welding quality of the flange 103.

[0041] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process is described in detail below.

[0042] Working principle: When in use, place the box body 1 on the support plate 301, then rotate the first hand wheel 306, and lift the support plate 301 through the worm 305 and the worm gear 304, so that the welding holes 101 at both ends of the box body 1 roughly reach the position of the positioning notch 402, and then insert one end of the connecting shaft 102 into the welding hole 101, and then continue to adjust the height of the box body 1 so that the end of the connecting shaft 102 away from the welding hole 101 can be stably pressed in the positioning notch 402, and at the same time make the side of the connecting shaft 102 close to the welding hole 101 and the box body 1 The inner walls of the connecting shafts 102 are on the same plane. At this time, the axes of the two connecting shafts 102 are on the same line. Then rotate the second hand wheel 505. The rotating second screw rod 501 drives the pressure plate 504 to move downward through the moving block 503, so that the bottom of the concave block is pressed on the top of the connecting shaft 102, and the connecting shaft 102 is fixed in the positioning notch 402. Then the welding work between the connecting shaft 102 and the box body 1 can be carried out. After the welding of the connecting shaft 102 and the box body 1 is completed, the flange 103 is symmetrically welded to the box body 1 to complete the welding work of the entire box body 1.

[0043] When welding the flange 103, the slider 702 is loosened by the locking bolt, and then the positioning seat 703 is moved so that the positioning block 704 is inserted into the flange 103 on the box body 1 to position the flange 103, and then the locking bolt is tightened to lock the position of the slider 70 to ensure that the two flanges 103 on the same side can be coaxially welded to meet the processing requirements of the box body 1. The welded flange 103 is used to install tires of warships and the like.
