[0013] The present invention has the following beneficial effects: (1) The present invention provides a pressure vessel tank body processing device. When in use, the unwelded circular plate is placed with its opening facing upward on two strip mounting boxes. At this time, a number of special-shaped grooved rubber wheels on the strip mounting boxes will support the unwelded circular plate. After receiving the force of the unwelded circular plate, the special-shaped grooved rubber wheels will move toward the strip mounting box. The special-shaped grooved rubber wheels drive the rotating rod to move, and the rotating rod drives the strip block to move. At this time, the support spring is compressed and deformed when it is subjected to the extrusion force of the strip block. The support spring generates a reaction force under the action of its own elastic force, so that the strip block and the special-shaped grooved rubber wheels will not move too much, so that the unwelded circular plate will not contact the fitting base. At this time, the unwelded circular plate is in a slidable hollow state, which provides flexibility when pushing the unwelded circular plate to move, thereby indirectly reducing the workload of manual labor. (2) The present invention provides a pressure vessel tank body processing device. The driving motor is started, and the driving motor drives the reciprocating screw to rotate. The reciprocating screw drives the limit movable block to move in a direction close to the driving motor. The limit movable block drives the bar limit rod to move. The bar limit rod drives the sliding mounting block to move. The sliding mounting block drives the rubber block to move. The rubber block will move downward under the action of the rectangular limit sliding groove and contact the inner wall of the unwelded circular plate. Under the friction of the rubber block, the unwelded circular plate will be driven to move in a direction close to the driving motor. At this time, the special-shaped grooved rubber wheel will rotate with the unwelded circular plate. Under the elastic force of the spring, the trapezoidal block will continuously perform telescopic movement and be inserted into different grooves of the special-shaped grooved rubber wheel. Since the thread on the reciprocating screw is reciprocating, the limit movable block will drive the rubber block to move when it moves away from the driving motor. At this time, since the trapezoidal block clamps the special-shaped grooved rubber wheel, the special-shaped grooved rubber wheel can only rotate clockwise, so the special-shaped grooved rubber wheel will not rotate when the rubber block moves back. Under the friction force of the special-shaped grooved rubber wheel, the rubber block will reset along the rectangular limit sliding groove. When the rubber block continuously moves back and forth, the unwelded circular plate will continuously move toward the direction of the driving motor. (3) The present invention provides a pressure vessel tank body processing device. When the unwelded circular plate contacts the trapezoidal plate, the trapezoidal plate moves away from the welding fixing box, the trapezoidal plate drives the driving rod to move, and the driving rod drives the Z-shaped rod to move toward the trapezoidal plate. At this time, the reset spring is compressed and deformed. When the Z-shaped rod leaves the limit groove, the locking of the rectangular rod is released. Since the unwelded circular plate is not welded, the position of the unwelded circular plate can be calibrated and clamped during the clamping process of the rotating roller. After the rectangular rod is unlocked, the opening of the unwelded circular plate will open under the action of gravity. At this time, the rotating roller will move toward the fixing sleeve due to the gravity of the unwelded circular plate. At this time, the unwelded circular plate will generate a downward force due to the loss of the fixing sleeve. (4) The present invention provides a pressure vessel tank body processing device. When the unwelded circular plate contacts the L-shaped ladder panel, the L-shaped ladder panel will drive the connecting rod to move in the direction away from the welding fixing box, and the connecting rod will drive the rectangular sliding block to move in the direction away from the driving motor. The rectangular sliding block drives the arc-shaped fixing block to move in the direction close to the unwelded circular plate. During the movement, the arc-shaped fixing block will contact the unwelded circular plate and drive the unwelded circular plate to descend. When the end of the unwelded circular plate contacts the back inner wall of the welding fixing box, the arc-shaped fixing block will also push the unwelded circular plate to fit tightly against the fitting base. At this time, the positioning and fixing of the unwelded circular plate are completed, the stability of the unwelded circular plate is improved, and shaking during welding that affects the welding effect is avoided.

[0014] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figure 1 - Fig.10 As shown in the figure, the present invention is a processing device for a pressure vessel tank body, including a welding fixing box 1. A reciprocating screw 2 is rotatably installed on the back inner wall of the welding fixing box 1. A driving motor 3 is fixedly installed on the back of the welding fixing box 1. The end of the reciprocating screw 2 extends outside the welding fixing box 1 and is fixedly connected to the driving motor 3. Two fitting bases 4 are fixedly installed on the bottom inner wall of the welding fixing box 1. An unwelded circular plate 501 is arranged in the welding fixing box 1. The device further includes: Two supporting mechanisms 5. The supporting mechanism 5 includes a strip-shaped installation box 502 fixedly installed on the back inner wall of the welding fixing box 1. A plurality of supporting springs 503 are fixedly installed on the left inner wall of the strip-shaped installation box 502. The right ends of the plurality of supporting springs 503 are fixedly installed with a strip-shaped block 504. A plurality of rotating rods 505 are rotatably installed on the strip-shaped block 504. Special-shaped grooved rubber wheels 506 are respectively fixedly sleeved on the plurality of rotating rods 505. The plurality of special-shaped grooved rubber wheels 506 are all in contact with the inner wall of the unwelded circular plate 501.

[0020] As Figure 4As shown, a strip groove 507 is provided on the right side of the strip block 504, a telescopic spring 508 is fixedly installed on the left inner wall of the strip groove 507, a long block 509 is fixedly installed on the right end of the telescopic spring 508, and a plurality of trapezoidal clamping blocks 510 are fixedly installed on the right side of the long block 509, and the plurality of trapezoidal clamping blocks 510 are respectively inserted into the grooves of the corresponding special-shaped grooved rubber wheels 506.

[0021] Since the trapezoidal clamping block 510 clamps the special-shaped grooved rubber wheel 506 , the special-shaped grooved rubber wheel 506 can only rotate clockwise, so the special-shaped grooved rubber wheel 506 will not rotate when the rubber block 805 moves back.

[0022] like Figure 4 and Figure 7 As shown, two clamping mechanisms 6 are provided on the welding fixing box 1, and the clamping mechanism 6 includes a rectangular rod 601 slidably installed on the right side of the welding fixing box 1, and the left end of the rectangular rod 601 extends into the welding fixing box 1, and the left end of the rectangular rod 601 is fixedly installed with an installation box 602, and a plurality of rotating rollers 603 are rotatably installed in the installation box 602, and the outer walls of the plurality of rotating rollers 603 are in contact with the outer walls of the unwelded circular plate 501, and a fixing sleeve 604 is fixedly provided on the rectangular rod 601, and a clamping spring 605 is provided on the rectangular rod 601, and the right end of the clamping spring 605 is fixedly connected to the fixing sleeve 604, and the left end of the clamping spring 605 is fixedly connected to the welding fixing box 1.

At this time, the rotating roller 603 will move toward the fixing sleeve 604 due to the gravity of the unwelded circular plate 501. At this time, the unwelded circular plate 501 will generate a downward force due to the loss of the fixation of the fixing sleeve 604.

[0024] like Figure 7 As shown, a sliding groove 606 is provided on the welding fixing box 1, a round rod 607 is fixedly installed in the sliding groove 606, a Z-shaped rod 608 is slidably sleeved on the round rod 607, a limiting groove 609 is provided on the back of the rectangular rod 601, the front end of the Z-shaped rod 608 extends into the limiting groove 609 and is slidably connected to the limiting groove 609, a return spring 610 is sleeved on the round rod 607, the front end of the return spring 610 is fixedly connected to the Z-shaped rod 608, and the end of the return spring 610 is fixedly connected to the sliding groove 606.

[0025] When the Z-shaped rod 608 leaves the limiting groove 609 , the locking of the rectangular rod 601 is released. Since the unwelded circular plate 501 is not welded, the position of the unwelded circular plate 501 can be calibrated and clamped during the clamping process of the rotating roller 603 .

[0026] like Figure 6As shown, a driving rod 611 is hinged and installed on a Z-shaped rod 608, and a trapezoidal plate 612 is slidably installed on a welding fixing box 1.

[0027] When the unwelded circular plate 501 contacts the trapezoidal plate 612, the trapezoidal plate 612 will move away from the welding fixing box 1. The trapezoidal plate 612 drives the driving rod 611 to move, and the driving rod 611 drives the Z-shaped rod 608 to move towards the trapezoidal plate 612.

[0028] As Figure 6 shown, two fixing mechanisms 7 are arranged on the welding fixing box 1. The fixing mechanism 7 includes an L-shaped ladder panel 701 slidably installed on the welding fixing box 1. The left end of the L-shaped ladder panel 701 extends into the welding fixing box 1. A connecting rod 702 is hinged and installed on the L-shaped ladder panel 701. A C-shaped plate 703 is fixedly installed on the top of the welding fixing box 1. A rectangular sliding block 704 is slidably sleeved on the C-shaped plate 703. A sliding long plate 705 is fixedly installed on the left end of the C-shaped plate 703. An arc-shaped fixing block 706 is slidably sleeved on the sliding long plate 705. A movable rod 707 is hinged and installed on the front surface of the arc-shaped fixing block 706. The front end of the movable rod 707 is hinged to the rectangular sliding block 704. The front end of the connecting rod 702 is hinged to the rectangular sliding block 704.

[0029] The L-shaped ladder panel 701 will drive the connecting rod 702 to move away from the welding fixing box 1. The connecting rod 702 will drive the rectangular sliding block 704 to move away from the driving motor 3. The rectangular sliding block 704 drives the arc-shaped fixing block 706 to move towards the unwelded circular plate 501. During the movement, the arc-shaped fixing block 706 will contact the unwelded circular plate 501 and drive the unwelded circular plate 501 to descend. When the end of the unwelded circular plate 501 contacts the inner wall of the back surface of the welding fixing box 1, the arc-shaped fixing block 706 will also push the unwelded circular plate 501 against the fitting base 4. At this time, the positioning and fixing of the unwelded circular plate 501 are completed, the stability of the unwelded circular plate 501 is improved, and the shaking during welding is avoided, which affects the welding effect.

[0030] As Fig. 9As shown, a conveying mechanism 8 is provided on the reciprocating screw 2, and the conveying mechanism 8 includes a limiting movable block 801 threadedly sleeved on the reciprocating screw 2, and the right and right sides of the limiting movable block 801 are respectively in contact with two strip mounting boxes 502, and the front end of the reciprocating screw 2 is rotatably installed with a limiting strip 802, and the end of the limiting strip 802 is fixedly connected to the back inner wall of the welding fixed box 1, and a rectangular limiting groove 803 is opened on the limiting strip 802, and a sliding mounting block 804 is slidably installed in the rectangular limiting groove 803, and a rubber block 805 is fixedly installed on the bottom of the sliding mounting block 804, and a strip limiting rod 806 is hingedly installed on the top of the sliding mounting block 804, and the top of the strip limiting rod 806 is hinged to the limiting movable block 801.

[0031] The reciprocating screw 2 drives the limit movable block 801 to move toward the direction close to the driving motor 3, the limit movable block 801 drives the strip limit rod 806 to move, the strip limit rod 806 drives the sliding mounting block 804 to move, the sliding mounting block 804 drives the rubber block 805 to move, and the rubber block 805 will move downward under the action of the rectangular limit slide groove 803 and contact the inner wall of the unwelded circular plate 501.

[0032] like Figure 1-10 As shown, a method for processing a pressure vessel body is provided, and the method steps are as follows: S1: initial support; S2: Push the plate to move; S3: Release the preliminary calibration; S4: Fix the plate.

[0033] When in use, the unwelded circular plate 501 is placed with the opening facing upward on the two strip installation boxes 502. At this time, the several special-shaped grooved rubber wheels 506 on the strip installation boxes 502 will support the unwelded circular plate 501. After receiving the force of the unwelded circular plate 501, the special-shaped grooved rubber wheels 506 will move towards the direction close to the strip installation boxes 502. The special-shaped grooved rubber wheels 506 drive the rotating rod 505 to move, and the rotating rod 505 drives the strip block 504 to move. At this time, the support spring 503 is compressed and deformed when it is squeezed by the strip block 504. The support spring 503 will be deformed under its own elastic force. Under the action, a reaction force is generated, so that the strip block 504 and the special-shaped grooved rubber wheel 506 will not move too much, so that the unwelded circular plate 501 will not contact the fitting base 4. At this time, the unwelded circular plate 501 is in a slidable hollow state, which provides flexibility when pushing the unwelded circular plate 501 to move, and indirectly reduces the workload of manual labor; start the driving motor 3, the driving motor 3 drives the reciprocating screw 2 to rotate, the reciprocating screw 2 drives the limit movable block 801 to move in the direction close to the driving motor 3, the limit movable block 801 drives the strip limit rod 806 to move, and the strip limit rod 806 drives The sliding mounting block 804 moves, and the sliding mounting block 804 drives the rubber block 805 to move. The rubber block 805 moves downward under the action of the rectangular limiting slide groove 803 and contacts the inner wall of the unwelded circular plate 501. The friction force of the rubber block 805 drives the unwelded circular plate 501 to move toward the direction close to the driving motor 3. At this time, the special-shaped grooved rubber wheel 506 rotates with the unwelded circular plate 501. Under the elastic force of the telescopic spring 508, the trapezoidal clamping block 510 continuously performs telescopic motion and is inserted into different grooves of the special-shaped grooved rubber wheel 506. Due to the reciprocating The thread on the screw rod 2 is reciprocating, and the limit movable block 801 will drive the rubber block 805 to move when it moves away from the driving motor 3. At this time, because the trapezoidal block 510 clamps the special-shaped grooved rubber wheel 506, the special-shaped grooved rubber wheel 506 can only rotate clockwise, so the special-shaped grooved rubber wheel 506 will not rotate when the rubber block 805 moves back. Under the friction force of the special-shaped grooved rubber wheel 506, the rubber block 805 will reset along the rectangular limit sliding groove 803. When the rubber block 805 keeps moving back and forth, the unwelded circular plate 501 will keep moving in the direction of the driving motor 3. When the unwelded circular plate 501 contacts the trapezoidal plate 612, the trapezoidal plate 612 will move in the direction away from the welding fixing box 1, the trapezoidal plate 612 drives the driving rod 611 to move, and the driving rod 611 drives the Z-shaped rod 608 to move in the direction close to the trapezoidal plate 612. At this time, the return spring 610 is compressed and deformed. When the Z-shaped rod 608 leaves the limiting groove 609, the locking of the rectangular rod 601 is released. Since the unwelded circular plate 501 is not welded, the position of the unwelded circular plate 501 can be calibrated during the clamping process of the rotating roller 603. After the rectangular rod 601 is unlocked, the opening of the unwelded circular plate 501 will open under the action of gravity. At this time, the rotating roller 603 will move in the direction close to the fixing sleeve 604 due to the gravity of the unwelded circular plate 501. At this time, the unwelded circular plate 501 will drop due to the loss of the fixation of the fixing sleeve 604. Force; when the unwelded circular plate 501 contacts the L-shaped ladder panel 701, the L-shaped ladder panel 701 will drive the connecting rod 702 to move in the direction away from the welding fixing box 1, and the connecting rod 702 will drive the rectangular sliding block 704 to move in the direction away from the driving motor 3, and the rectangular sliding block 704 will drive the arc-shaped fixing block 706 to move in the direction close to the unwelded circular plate 501. During the movement, the arc-shaped fixing block 706 will contact the unwelded circular plate 501 and drive the unwelded circular plate 501 to descend. When the end of the unwelded circular plate 501 contacts the back inner wall of the welding fixing box 1, the arc-shaped fixing block 706 will also push the unwelded circular plate 501 to fit tightly against the fitting base 4. At this time, the positioning and fixing of the unwelded circular plate 501 are completed, thereby improving the stability of the unwelded circular plate 501 and avoiding shaking during the welding process that affects the welding effect.

8. A method for using a pressure vessel body processing device, using the pressure vessel body processing device according to claim 7, characterized in that: The method steps are as follows: S1: When in use, place the un-welded circular plate (501) with the opening facing upwards on the two strip-shaped mounting boxes (502). At this time, a plurality of special-shaped grooved rubber wheels (506) on the strip-shaped mounting boxes (502) will support the un-welded circular plate (501). After being subjected to the force of the un-welded circular plate (501), the special-shaped grooved rubber wheels (506) will move towards the direction close to the strip-shaped mounting boxes (502). The special-shaped grooved rubber wheels (506) drive the rotating rod (505) to move, and the rotating rod (505) drives the strip-shaped block (504) to move. At this time, the support spring (503) undergoes a compressive deformation when subjected to the extrusion force of the strip-shaped block (504). The support spring (503) will generate a reaction force under the action of its own elastic force, so that the strip-shaped block (504) and the special-shaped grooved rubber wheels (506) will not move too much, and the un-welded circular plate (501) will not contact the fitting base (4). At this time, the un-welded circular plate (501) is in a slidable hollow state; S2: starting the driving motor (3), the driving motor (3) drives the reciprocating screw (2) to rotate, the reciprocating screw (2) drives the limit movable block (801) to move in a direction close to the driving motor (3), the limit movable block (801) drives the bar limit rod (806) to move, the bar limit rod (806) drives the sliding mounting block (804) to move, the sliding mounting block (804) drives the rubber block (805) to move, the rubber block (805) will move downward under the action of the rectangular limit slide groove (803) and contact the inner wall of the unwelded circular plate (501), the friction force of the rubber block (805) will drive the unwelded circular plate (501) to move in a direction close to the driving motor (3), at this time, the special-shaped grooved rubber wheel (506) will rotate with the unwelded circular plate (501), and the expansion spring (508) will rotate. Under the elastic force, the trapezoidal clamping block (510) will continuously perform telescopic movement and insert into different grooves of the special-shaped grooved rubber wheel (506). Since the thread on the reciprocating screw (2) is reciprocating, the limit movable block (801) will drive the rubber block (805) to move when it moves in a direction away from the drive motor (3). At this time, since the trapezoidal clamping block (510) clamps the special-shaped grooved rubber wheel (506), the special-shaped grooved rubber wheel (506) can only rotate clockwise. Therefore, the special-shaped grooved rubber wheel (506) will not rotate when the rubber block (805) moves back. Under the friction force of the special-shaped grooved rubber wheel (506), the rubber block (805) will reset along the rectangular limit sliding groove (803). When the rubber block (805) continuously moves back and forth, the unwelded circular plate (501) will continuously move in the direction of the drive motor (3); S3: When the unwelded circular plate (501) contacts the trapezoidal plate (612), the trapezoidal plate (612) moves away from the welding fixing box (1), the trapezoidal plate (612) drives the driving rod (611) to move, and the driving rod (611) drives the Z-shaped rod (608) to move toward the trapezoidal plate (612). At this time, the return spring (610) is compressed and deformed. When the Z-shaped rod (608) leaves the limiting groove (609), the locking of the rectangular rod (601) is released. The circular plate (501) is not welded, and the position of the unwelded circular plate (501) can be calibrated during the process of being clamped by the rotating roller (603). After the rectangular rod (601) is unlocked, the opening of the unwelded circular plate (501) will open under the action of gravity. At this time, the rotating roller (603) will move towards the fixing sleeve (604) due to the gravity of the unwelded circular plate (501). At this time, the unwelded circular plate (501) will generate a downward force due to the loss of the fixing sleeve (604). S4: When the unwelded circular plate (501) contacts the L-shaped ladder panel (701), the L-shaped ladder panel (701) drives the connecting rod (702) to move in a direction away from the welding fixing box (1), and the connecting rod (702) drives the rectangular sliding block (704) to move in a direction away from the driving motor (3). The rectangular sliding block (704) drives the arc-shaped fixing block (706) to move in a direction close to the unwelded circular plate (501). During the movement, the arc-shaped fixing block (706) contacts the unwelded circular plate (501) and drives the unwelded circular plate (501) to descend. When the end of the unwelded circular plate (501) contacts the back inner wall of the welding fixing box (1), the arc-shaped fixing block (706) also pushes the unwelded circular plate (501) to fit tightly against the fitting base (4). At this time, the positioning and fixing of the unwelded circular plate (501) are completed.
