Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 5 As shown in this embodiment, a welding apparatus for the production and processing of ethylene tanks includes:

[0029] Base 1, on which is placed an ethylene cylinder 100 to be welded;

[0030] The V-shaped supports 2 consist of four sets, fixedly connected to the top of the base 1 at equal intervals in the front-to-back direction. Two support wheels 201 are rotatably installed on the inner walls of both sides of the V-shaped supports 2. The support wheels 201 are in movable contact with the bottom outer side of the ethylene cylinder 100 to be welded. Support rods 202 are fixedly connected between the two sides of the V-shaped supports 2 and the top of the base 1. The outer side of the support wheels 201 is fitted with anti-collision rubber sleeves. The anti-collision rubber sleeves are used to reduce the hard impact when the ethylene cylinder 100 to be welded is placed inward. The V-shaped supports 2, together with the four support wheels 201 on their inner side, form a V-shaped movable support effect at the bottom. The V-shaped support method, with the spacing decreasing from top to bottom, is convenient and applicable to the movable support of ethylene cylinders 100 to be welded of various diameter specifications.

[0031] The PLC controller 3 is fixedly installed on the bottom left side of the V-shaped support 2 on the front side;

[0032] The pressure-controlled vertical guide drive assembly is fixedly installed on the top of the base 1 and electrically connected to the PLC controller 3;

[0033] The friction rotary drive assembly is fixedly installed on the top of the pressure-controlled vertical guide drive assembly and contacts the bottom of the ethylene cylinder 100 to be welded. The pressure-controlled vertical guide drive assembly is used to drive the friction rotary drive assembly upward to press and squeeze the ethylene cylinder 100 to be welded under controlled pressure, and the friction rotary drive assembly is used to drive the ethylene cylinder 100 to be welded to rotate after pressing.

[0034] Specifically, the pressure-controlled vertical guide drive assembly includes a lifting seat 401 positioned between two V-shaped supports 2 at the frontmost side. A pressure sensor 402 is fixedly installed at the bottom of the lifting seat 401. A multi-stage electric telescopic rod 4, with its extended end fixedly connected to the bottom of the pressure sensor 402, is fixedly installed at the top of the base 1. Two vertical guide sleeves 404 are fixedly connected to both sides of the lifting seat 401. A vertical guide rod 403, fixedly connected to the top of the base 1, is slidably fitted inside the vertical guide sleeve 404. The pressure sensor 402 and the multi-stage electric telescopic rod 4 are both electrically connected to the PLC controller 3. The lifting seat 401, pressure sensor 402, and multi-stage electric telescopic rod are configured as follows: 4. The vertical guide sleeve 404 and the vertical guide rod 403 cooperate. The PLC controller 3 uses a preset pressure value to control the closing of the multi-stage electric telescopic rod 4. The multi-stage electric telescopic rod 4 is started in the forward direction, causing the pressure sensor 402 to move upward. The pressure sensor 402 drives the lifting seat 401 to move upward. When the lifting seat 401 moves upward to the point where it can no longer move upward, the pressure sensor 402 detects the upward pressing force applied by the multi-stage electric telescopic rod 4 and transmits it to the PLC controller 3. When the preset value is reached, the PLC controller 3 controls the multi-stage electric telescopic rod 4 to close automatically, thereby achieving the effect of driving the lifting seat 401 to rise and adjust and control and tighten it.

[0035] Furthermore, the friction rotary drive assembly includes a fixed box 5 fixedly connected to the top of the lifting seat 401. A rotating shaft 501 is rotatably installed between the front and rear inner walls of the fixed box 5. A circular through hole is provided on the rear side of the fixed box 5. Bearings are fixedly installed in the circular through hole and on the front inner wall of the fixed box 5. The inner ring of the bearing is fixedly fitted with the outer side of the rotating shaft 501, which achieves the effect of rotating the rotating shaft 501. The rear end of the rotating shaft 501 extends to the rear side of the fixed box 5 and a rotating wheel 505 is welded and fixed thereon. An anti-slip rubber sleeve 506 is adhesively fitted on the outer side of the rotating wheel 505. The top of the anti-slip rubber sleeve 506 contacts the bottom of the ethylene cylinder 100 to be welded. A large gear 502 located inside the fixed box 5 is fixedly fitted on the outer side of the rotating shaft 501. A small gear 503 meshes with the bottom of the large gear 502. A drive motor 504 with an output shaft fixedly connected to the front side of the small gear 503 is fixedly installed on the front side of the fixed box 5. The drive motor 504 is electrically connected to the PLC controller 3.

[0036] The fixed box 5, rotating shaft 501, rotating wheel 505, anti-slip rubber sleeve 506, large gear 502, small gear 503, and drive motor 504 work together to sequentially move the anti-slip rubber sleeve 506 upwards via the fixed box 5, rotating shaft 501, and rotating wheel 505 as the lifting seat 401 moves upwards. This continues until the anti-slip rubber sleeve 506 is pressed tightly against the bottom of the ethylene cylinder 100 to be welded, preventing further upward movement. When the lifting seat 401 is pressed under controlled pressure, the anti-slip rubber sleeve 506 is driven upwards to press tightly against the ethylene cylinder 100 to be welded. This controlled pressure pressing method ensures tight contact between the two, and the set pressure value is less than that of the ethylene cylinder 100 to be welded. The weight of the ethylene cylinder 100 is used to prevent it from being lifted. The drive motor 504 drives the pinion 503 to rotate. The pinion 503 drives the large gear 502 meshing with it to rotate slowly. The large gear 502 drives the rotating wheel 505 to rotate through the rotating shaft 501. The rotating wheel 505 drives the ethylene cylinder 100 to be welded to rotate slowly through the friction of the anti-slip rubber sleeve 506. By driving the ethylene cylinder 100 to be welded to rotate, when the operator operates the welding gun to perform a full circle welding, he only needs to weld on one side. This reduces the effort caused by the operator walking back and forth around the ethylene cylinder 100 to be welded and the inconvenience caused by the dragging of the welding gun tube.

[0037] Furthermore, a welding station is formed between the two V-shaped supports 2 in the middle, and the welding station is either one side of the ethylene cylinder 100 to be welded.

[0038] The method of use in this embodiment is as follows: When using the welding device for ethylene tank production and processing, the ethylene round tank 100 to be welded is suspended inside the two corresponding V-shaped supports 2 and in contact with the corresponding multiple support wheels 201. The multiple support wheels 201 provide movable support for the ethylene round tank 100 to be welded. The unobstructed upper part facilitates the direct hoisting and placement of the heavier ethylene round tank 100 to be welded, providing convenience for hoisting and lifting operations. In addition, the V-shaped support method with the spacing decreasing from top to bottom facilitates the movable support of ethylene round tanks 100 to be welded of various diameter specifications, improving applicability.

[0039] The pressure value for closing the multi-stage electric telescopic rod 4 is pre-set using the PLC controller 3, and the delay control command time for controlling the drive motor 504 is set to 2-3 minutes using the PLC controller 3. The multi-stage electric telescopic rod 4 is then started in the forward direction, causing the pressure sensor 402 to move upward. The pressure sensor 402 drives the lifting seat 401 to move upward, and the lifting seat 401 drives the four vertical guide sleeves 404 to slide upward on their corresponding vertical guide rods 403, performing vertical guiding work. As the lifting seat 401 moves upward, it sequentially drives the anti-slip rubber sleeve 506 upward through the fixed box 5, the rotating shaft 501, and the rotating wheel 505 until the anti-slip rubber sleeve 506... When the multi-stage electric telescopic rod 4 continues to apply lifting force to the pressure sensor 402, the pressure sensor 402 detects the squeezing force applied by the multi-stage electric telescopic rod 4 and transmits the pressure value to the PLC controller 3. When the preset value is reached, the PLC controller 3 controls the multi-stage electric telescopic rod 4 to automatically close, thereby adjusting the height of the anti-slip rubber sleeve 506 and squeezing it tightly with the ethylene cylinder 100 to be welded under controlled pressure. By using the controlled pressure squeezing method, the two are ensured to be tightly squeezed and contacted, and the set pressure value is less than the weight of the ethylene cylinder 100 to be welded to prevent it from being lifted.

[0040] Within the time delay control command period for starting the drive motor 504, personnel use a welding torch to first weld a portion of the side splicing position, initially forming a single unit from the front and rear sections of the ethylene cylinder 100 to be welded. Upon reaching the time delay control command period, the PLC controller 3 controls the drive motor 504 to start. The drive motor 504 drives the pinion gear 503 to rotate, which in turn drives the meshing large gear 502 to rotate slowly. The large gear 502, through the rotating shaft 501, drives the rotating wheel 505 to rotate. The rotating wheel 505 is protected by an anti-slip rubber sleeve. The friction of 506 drives the ethylene cylinder 100 to be welded to rotate slowly. Since the front and rear ends have been preliminarily welded to form a fixed whole, the cylinder rotates as a whole. By driving the ethylene cylinder 100 to be welded to rotate, when the operator operates the welding gun to perform a full circle of welding, he only needs to weld on one side. This reduces the effort required for the operator to walk back and forth around the ethylene cylinder 100 to be welded and the inconvenience caused by dragging the welding gun tube. It also avoids the phenomenon that the welding is interrupted due to dragging the welding gun tube, which affects the welding accuracy, thus improving the convenience and labor saving of welding.

[0041] The PLC controller 3, pressure sensor 402, multi-stage electric telescopic rod 4, and drive motor 504 in this utility model are well known to those skilled in the art and belong to conventional methods or common knowledge. Those skilled in the art can arbitrarily select and match them according to their needs or convenience. In addition, the PLC controller 3 receives the pressure value transmitted by the pressure sensor 402 and controls the multi-stage electric telescopic rod 4 to close when the preset value is reached. The drive motor 504 is started by delay control through editing and setting the start-up delay (timing) control command. These are basic numerical control setting control methods of programmable controllers well known to those skilled in the art. They all belong to conventional methods or common knowledge of programmable controllers for programmers and will not be described in detail here.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
