The corrosion resistance of stainless steel makes stainless steel storage tanks meet the production needs of various materials.

[0003] At present, when welding V-shaped stainless steel storage tanks, it is necessary to butt-joint two cut stainless steel cylinder bodies, and then weld the gap between the cylinder bodies. When butt-jointing the two cylinder bodies, due to their large volume, there are errors in manual butt-jointing, and since they cannot be effectively fixed after butt-jointing, misalignment may occur during the welding process, resulting in the quality of the welded product not meeting the requirements, and ultimately requiring rework, which seriously affects production efficiency.

[0032] 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.

[0033] 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.

[0034] like Figure 1 , 3 As shown in , 4, and 6, in one embodiment, a high-efficiency welding device for a stainless steel storage tank is proposed, and the device includes:

[0035] The main frame 1 includes a mounting platform 101 disposed on the main frame 1;

[0036] Adjustment mechanism 2: includes a rotating cylinder 203 and a cylinder body 204 mounted on the mounting platform 101. Four limiting balls 201 are inserted into the cylinder body 204 and are slidably connected to the limiting balls 201. Each limiting ball 201 is slidably connected to the inner wall of the rotating cylinder 203 through a limiting spring 202. The tracks formed by the four limiting balls 201 are contoured to the inclined surface of the cylinder body 204.

[0037] Release mechanism 3: used to cancel the limit of the cylinder body 204 by the limit ball 201;

[0038] Rotation mechanism 5: used to drive the rotating cylinder 203 to rotate, so that the limiting balls 201 are in contact with the cylinder body 204;

[0039] Rotation mechanism 6: used to tilt the cylinder body 204 by rotation, so that the cylinder body 204 moves along the direction of gravity.

[0040] In practical application, the embodiment of the present invention is as follows: Figure 1 As shown, when the cylinder body 204 is docked, as shown in Figure 3 As shown, from Figure 3 , and with Figure 3 Taking the right half of the device as an example, at this time, the cylinder body 204 slides to the left through the rotating mechanism 6 under the action of external force. The cylinder body 204 is pushed by external force here to avoid the cylinder body 204 from sliding rapidly under the action of gravity and impacting the limiting ball 201, thereby increasing the service life of the device. At this time, the operation of the rotating mechanism 6 drives the cylinder body 204 to rotate counterclockwise. Under the action of gravity and the rotating mechanism 6, the cylinder body 204 slides to the left and fits the surface of the limiting ball 201. At the same time, as the rotating mechanism 6 rotates, the rotating cylinder 203 rotates under the action of the rotation mechanism 5. At this time, the rotation of the rotating cylinder 203 causes the limiting ball 201 to rotate synchronously, and the cylinder body 204 will not rotate under the limiting action of the rotating mechanism 6. As the rotating mechanism 6 drives the rotating cylinder 203 to revolve ninety degrees, the limiting ball 201 rotates one circle. Figure 6 As shown, since the trajectories of the four limiting balls 201 are contoured with the cylinder body 204, during the rotation process, the inclined surface of the cylinder body 204 falls onto the four limiting balls 201. At this time, the cylinder body 204 is out of contact with the rotating mechanism 6, and the rotating mechanism 6 is reversed forty-five degrees. The self-rotating mechanism 5 no longer drives the rotating cylinder 203 to rotate. At this time, the positioning of the cylinder body 204 is completed, and the inclined surface of the cylinder body 204 is vertically downward, thereby achieving the purpose of accurately positioning the cylinder body 204. It should be noted here that four limiting balls 201 are provided here, but a plurality of limiting balls 201 can be provided in actual production to ensure the stability of the relative motion between the cylinder body 204 and the limiting balls 201. At the same time, during the reversal of the rotating mechanism 6, as shown in FIG. Figure 4 As shown, under the action of the release mechanism 3, the limiting ball 201 is driven to move to a position away from the central axis of the rotating cylinder 203. When the rotating mechanism 6 reverses forty-five degrees, the limiting ball 201 no longer restricts the cylinder body 204. The cylinder bodies 204 at both ends drop together and fit together under the action of gravity, and will not fall off under the limit of the rotating cylinder 203. Therefore, the two cylinder bodies 204 are pressed against each other by gravity to ensure that there is no misalignment during welding.

[0041] like Figure 4 and Fig. 9As shown, as a preferred embodiment of the present invention, the release mechanism 3 includes an L-shaped connecting rod 301 fixedly connected to the limiting ball 201, the surface of the L-shaped connecting rod 301 is rotatably connected to a swing rod 302, one end of the swing rod 302 away from the L-shaped connecting rod 301 is rotatably connected to the surface of a connecting ring 303, the surface of the connecting ring 303 is coaxially contacted with a sliding ring 304, and the inner wall of the connecting ring 303 is slidably connected to the surface of the rotating mechanism 6, the inner wall of the sliding ring 304 is slidably connected to a telescopic rod 306, the telescopic rod 306 is connected to the inner wall of the sliding ring 304 through a compression spring 305, the telescopic rod 306 is slidably connected to the inner wall of the slide groove mechanism 4, and the sliding ring 304 is slidably connected to the inner wall of the rotating mechanism 6.

[0042] In practical application, the embodiment of the present invention is as follows: Fig. 9 As shown, when the rotating mechanism 6 rotates, the telescopic rod 306 slides along the track of the sliding groove mechanism 4, and the telescopic rod 306 does not move relative to the sliding groove mechanism 4. Fig. 9 As shown, at this time, the trajectory radius of the chute mechanism 4 gradually increases, as shown in FIG. Figure 4 As shown, from Figure 4 When viewed from the front direction, the telescopic rod 306 moves to the left, and the telescopic rod 306 drives the connecting ring 303 to move to the left through the sliding ring 304, and then drives the L-shaped connecting rod 301 to move away from the central axis of the rotating cylinder 203 through the swing of the swing rod 302, so that the limiting ball 201 is away from the central axis of the rotating cylinder 203, thereby releasing the limiting effect on the cylinder body 204, and allowing the cylinder body 204 to slide down and splice under the action of gravity, thereby achieving the purpose of releasing the limit of the cylinder body 204 and automatically fitting it.

[0043] like Figure 4 , Figure 8 and Fig. 9 As shown, as another preferred embodiment of the present invention, the slide mechanism 4 includes a slide disc 401 in contact with the mounting platform 101, and the interior of the slide disc 401 is provided with an equal-diameter slide 402 and a variable-diameter slide 403 connected end to end, and the surface of the equal-diameter slide 402 is in contact with the surface of the telescopic rod 306.

[0044] In practical application, the embodiment of the present invention is as follows: Fig. 9 As shown, when the rotating mechanism 6 rotates, the telescopic rod 306 slides along the track of the equal-diameter slide groove 402. When it moves to the end of the equal-diameter slide groove 402, due to the height difference between the equal-diameter slide groove 402 and the variable-diameter slide groove 403, as shown in FIG. Figure 4 As shown, at this time, under the action of the compression spring 305, the telescopic rod 306 contacts the variable diameter slide groove 403, and when the rotating mechanism 6 is reversed, as shown in FIG. Fig. 9 As shown, at this time, the trajectory radius of the variable diameter chute 403 gradually increases, as shown in FIG. Figure 4 As shown, from Figure 4 When viewed from the front direction, the telescopic rod 306 moves to the left, and the telescopic rod 306 drives the connecting ring 303 to move to the left through the sliding ring 304, and then drives the L-shaped connecting rod 301 to move away from the central axis of the rotating cylinder 203 through the swing of the swing rod 302, so that the limiting ball 201 is away from the central axis of the rotating cylinder 203, thereby releasing the limiting effect on the cylinder body 204, and allowing the cylinder body 204 to slide down and splice under the action of gravity, thereby achieving the purpose of releasing the limit of the cylinder body 204 and automatically fitting it.

[0045] like Figure 5 As shown, as another preferred embodiment of the present invention, the rotation mechanism 5 includes a fixed cone disk 501 coaxially fixedly mounted on the surface of the rotating cylinder 203, the fixed cone disk 501 is provided with ratchet teeth, the fixed cone disk 501 is meshed with a conical rack 502, and the conical rack 502 is fixedly mounted on the surface of the slide groove disc 401.

[0046] In practical application, the embodiment of the present invention is as follows: Figure 5 As shown, when the rotating mechanism 6 drives the rotating cylinder 203 to revolve, the rotating cylinder 203 is driven to rotate by itself under the meshing action of the fixed cone disk 501 and the bevel rack 502, and then the limiting ball 201 is driven to rotate by itself. When the rotating mechanism 6 revolves ninety degrees, the fixed cone disk 501 drives the rotating cylinder 203 to rotate one circle, so that the inclined surface of the cylinder body 204 fits the trajectory of the limiting ball 201 during the process of the limiting ball 201 rotating one circle. At this time, the cylinder body 204 is separated from the limiting action of the rotating mechanism 6 and falls on the limiting ball 201, so as to perform preliminary positioning, thereby ensuring the accuracy of the subsequent docking of the two cylinder bodies 204.

[0047] like Figure 3 As shown, as another preferred embodiment of the present invention, the rotating mechanism 6 includes a rotating motor 601 fixedly mounted on the surface of the slide groove disc 401, the output end of the rotating motor 601 passes through the slide groove disc 401 and is fixedly mounted with a follower drum 602, a plurality of transmission wheels 603 are rotatably mounted on the surface of the follower drum 602, the transmission wheels 603 are in contact with the surface of the cylinder body 204, the surface of the follower drum 602 is slidably connected with a connecting ring 303 and a sliding ring 304, and the transmission wheel 603 is coaxially rotatably connected with the rotating drum 203.

[0048] In practical application, the embodiment of the present invention is as follows: Figure 3 As shown, from Figure 3Looking from the front and back, when the cylinder body 204 approaches the limiting ball 201 through the transportation effect of the transmission wheel 603 under the action of external force, the rotating motor 601 starts to run, and the operation of the rotating motor 601 drives the follower drum 602 to rotate, and then drives the cylinder body 204 to rotate. At this time, under the gravity of the cylinder body 204 and the guiding effect of the transmission wheel 603, the cylinder body 204 moves to the left, and the cylinder body 204 contacts the limiting ball 201, so as to accurately position the cylinder body 204 when the limiting ball 201 rotates subsequently.

[0049] like Figure 2 As shown, as another preferred embodiment of the present invention, the device also includes a thrust mechanism 7, which includes a thrust motor 701 fixedly mounted on the follower drum 602, the output end of the thrust motor 701 passes through the follower drum 602 and is fixedly connected with a rotating gear 702, the rotating gear 702 is meshed with a moving rod 703, and the moving rod 703 passes through the follower drum 602 and is slidably connected to the follower drum 602.

[0050] In actual application of the embodiment of the present invention, when the cylinder body 204 is docked, as shown in FIG. Figure 2 As shown, at this time, the thrust motor 701 starts to run, and the thrust motor 701 drives the rotating gear 702 to rotate, thereby driving the moving rod 703 to move laterally, and the moving rod 703 pushes the cylinder body 204 to move laterally along the transmission wheel 603, thereby preventing the cylinder body 204 from impacting the limiting ball 201 under the action of gravity, thereby achieving the purpose of increasing the movement stability.

[0051] like Figure 7 As shown, as another preferred embodiment of the present invention, the device also includes a feeding mechanism 8, the feeding mechanism 8 includes a feeding motor 801 fixedly mounted on the mounting table 101, a feeding cone disk 802 is fixedly mounted on the output end of the feeding motor 801, two secondary bevel gears 803 are meshed on the surface of the feeding cone disk 802, a rotating screw 804 is coaxially fixedly mounted on the surface of the secondary bevel gear 803, the rotating screw 804 and the screw slider 805 form a spiral pair transmission, the surface of the screw slider 805 is fixedly mounted with a slide groove disc 401, and the rotating screw 804 is rotatably connected to the slide groove disc 401.

[0052] In practical application, the embodiment of the present invention is as follows: Figure 7 As shown, after the welding of the cylinder body 204 is completed, the unloading motor 801 starts to run, and the unloading motor 801 drives the unloading cone 802 to rotate, and then drives the rotating screw 804 to rotate. The rotation of the rotating screw 804 drives the screw slider 805 to move obliquely upward along the central axis of the rotating screw 804. At this time, the cylinder body 204 is separated from the rotating cylinder 203, so as to achieve the purpose of automatically and quickly unloading the welded cylinder body 204.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.
