Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-Figure 9 The present invention provides a technical solution: a welding device for assembling a spherical storage tank, comprising a processing table 1 and a welding mechanism 2 arranged on the processing table 1, a clamping seat 3 is rotatably arranged on the top of the processing table 1, a plurality of limiting components 4 for limiting the spherical tank flaps are arranged on the clamping seat 3, a rotating turntable 5 is rotatably arranged inside the clamping seat 3, a power piece 501 is fixedly arranged inside the clamping seat 3, the power piece 501 is a servo motor, can be rotated forward and reversely, and is electrically connected to an external power supply; the output shaft of the power piece 501 is fixedly arranged at the center of the rotating turntable 5, and the rotating turntable 5 is driven to rotate by starting the power piece 501; wherein, the rotating turntable 5 rotates to drive the limiting components 4 to drive the plurality of spherical tank flaps to approach each other until their edge portions are in contact;

[0035] A support column 6 is rotatably arranged inside the processing table 1, and the clamping seat 3 is fixedly arranged on the top of the support column 6. The setting of the support column 6 provides support for the clamping seat 3 to improve its stability; a locking structure 7 is arranged inside the processing table 1 to limit the support column 6, so that the support column 6 can only rotate intermittently in a certain direction.

[0036] A driving member 8 is fixedly arranged on the processing table 1. The driving member 8 is an electric push rod, and its oil inlet is connected to the oil outlet of the external oil pump. A connecting rod 10 is slidably arranged inside the processing table 1, and the output end of the driving member 8 is fixedly arranged on the connecting rod 10, so that the connecting rod 10 is driven to reciprocate in the horizontal direction by starting the driving member 8; the driving member 8 drives the welding mechanism 2 to move in the horizontal direction, wherein, when the driving member 8 drives the welding mechanism 2 to move to the left, the support column 6 is driven to rotate through the transmission connection assembly 9, and the support column 6 is limited by the locking structure 7 after the rotation angle.

[0037] Among them, regarding the design scheme of the limiting component 4, the limiting component 4 includes a movable seat 401 that is slidably arranged on the clamping seat 3, and a plurality of movable seats 401 are arranged and distributed in a circular array; a movable through groove is opened through the clamping seat 3, and the movable seat 401 passes through the movable through groove and is slidably arranged with its inner surface, thereby improving the stability of the movable seat 401 during movement; a support seat 402 is fixedly arranged on one side of the movable seat 401 for supporting and limiting the bottom of the spherical tank flap, and an arc-shaped placement groove with open ends is opened on the top of the support seat 402, so that the bottom of the spherical tank flap can be snapped into the arc-shaped placement groove to initially limit the spherical tank flap; a magnetic suction block 403 is fixedly arranged on one side of the movable seat 401 for limiting the outer top of the spherical tank flap, and the spherical tank flap is limited and fixed through the cooperation of the magnetic suction block 403 and the support seat 402.

[0038] As a further technical solution, a convex column 404 is fixedly provided at the bottom of the movable seat 401, a guide groove 405 is provided on the inner bottom wall of the clamping seat 3, one end of the convex column 404 extends into the guide groove 405 and is slidably provided with the inner surface thereof; an arc-shaped adjustment groove 406 with an inclined design is provided through the rotating turntable 5, wherein the convex column 404 passes through the arc-shaped adjustment groove 406. When the rotating turntable 5 rotates, the arc-shaped adjustment groove 406 on its surface is driven to rotate around its axis, and at the same time, under the limiting action of the guide groove 405, the arc-shaped adjustment groove 406 pushes the convex column 404 to move along the inner surface of the guide groove 405, thereby driving the multiple movable seats 401 to approach each other, thereby driving the spherical tank petals to approach each other, until the edges of two adjacent spherical tank petals are fitted together.

[0039] Among them, regarding the design scheme of the transmission connection component 9, the transmission connection component 9 includes an extension rod 901 fixedly arranged on the outer surface of the connecting rod 10, a transmission rod 902 is rotatably arranged on the extension rod 901, and a plurality of baffle rods 903 are fixedly arranged on the outer surface of the support column 6, and the number of baffle rods 903 is the same as the number of movable seats 401, and are distributed in a circular array on the outer surface of the support column 6; wherein, when the driving member 8 drives the extension rod 901 to move to the left through the connecting rod 10, the transmission rod 902 pushes the baffle rod 903 to drive the support column 6 to rotate. When the telescopic end of the driving member 8 is shortened, it drives the connecting rod 10 to move to the left, and the connecting rod 10 drives the extension rod 901 to move, and the extension rod 901 drives the transmission rod 902 to move synchronously, so that the transmission rod 902 gradually approaches the baffle rod 903 and contacts it, and the transmission rod 902 continues to move, pushing the baffle rod 903, so that it drives the support column 6 to rotate until the transmission rod 902 disengages from the baffle rod 903 and the support column 6 stops rotating; during the rotation process, the support column 6 drives the clamping seat 3 to rotate synchronously, and the clamping seat 3 drives the ball tank petal to rotate, so that the next welding point to be rotated is rotated to the bottom of the welding mechanism 2 for welding operation.

[0040] As a further technical solution, the end of the extension rod 901 extends outward to form a limiting portion 904, one side of the transmission rod 902 is in contact with the limiting portion 904, and a reset elastic member 905 is fixedly provided between the other side of the transmission rod 902 and the extension rod 901. The reset elastic member 905 is a spring, and its elastic coefficient can be set according to requirements. When the extension rod 901 drives the transmission rod 902 to move to the right, the support column 6 is locked by the locking structure 7, so that the transmission rod 902 continues to move after contacting the stop rod 903, the reset elastic member 905 is compressed, and the transmission rod 902 rotates around the connection with the extension rod 901 until the transmission rod 902 is disengaged from the stop rod 903, and the transmission rod 902 is reset by the reset elastic member 905 and returns to its initial state; when the extension rod 901 drives the transmission rod 902 to move to the left, after the transmission rod 902 contacts the stop rod 903, the transmission rod 902 cannot rotate under the limiting action of the limiting part 904, thereby pushing the stop rod 903 to drive the support column 6 to rotate.

[0041] Among them, regarding the design scheme of the locking structure 7, the locking structure 7 includes a locking rod 701 fixedly arranged inside the processing table 1, a fixed gear disc 702 is fixedly arranged on the top of the locking rod 701, a movable gear disc 703 is slidably arranged on the outer surface of the support column 6, the movable gear disc 703 is meshed with the fixed gear disc 702, and a locking elastic member 704 is fixedly arranged on the outer surface of the support column 6. The locking elastic member 704 is a spring, and its elastic coefficient can be set according to requirements. The elastic coefficient of the locking elastic member 704 is greater than the elastic coefficient of the reset elastic member 905; wherein, one end of the locking elastic member 704 is fixedly connected to the top of the movable gear disc 703.

[0042] When the extension rod 901 drives the transmission rod 902 to move to the left, the transmission rod 902 gradually approaches the baffle rod 903 and contacts it. Since the transmission rod 902 is limited by the limiting part 904, the transmission rod 902 cannot rotate. Therefore, the transmission rod 902 continues to move, which will push the baffle rod 903. The baffle rod 903 drives the support column 6 to rotate, and the support column 6 drives the movable gear plate 703 to rotate. Since the position of the fixed gear plate 702 is limited, the movable gear plate 703 moves up and down along the outer surface of the support column 6 under the action of the fixed gear plate 702 and the locking elastic member 704. When the transmission rod 902 is disengaged from the baffle rod 903, the movable gear plate 703 is engaged with the fixed gear plate 702 again, so that the support column 6 cannot rotate, thereby preventing the position of the ball tank petal from moving during the processing and affecting the welding effect.

[0043] Among them, regarding the design scheme of the welding mechanism 2, the welding mechanism 2 includes a mounting frame 201 that passes through the top of the processing table 1 and is slidably arranged with the inner surface thereof, and the inner wall of the mounting frame 201 on the side close to the support column 6 is designed in an arc shape, and has the same curvature as the outer surface of the spherical tank petal; the top end of the connecting rod 10 is fixedly arranged with the mounting frame 201, and a support block 202 is slidably arranged inside the side of the mounting frame 201 close to the support column 6, and a welding head 203 is fixedly arranged on one side of the support block 202, and the welding head 203 adopts the existing technology, which is common knowledge known to those skilled in the art, so it is not described in detail; the mounting frame 201 An elastic telescopic rod 204 is rotatably arranged inside the mounting frame 201, and the elastic telescopic rod 204 is composed of two supporting rods plugged into each other between opposite ends, and a connecting spring is fixedly arranged between the opposite ends of the two supporting rods. When the support block 202 is farthest from the rotating member 205, the connecting spring is at its original length; and one end of the elastic telescopic rod 204 is rotatably arranged with the support block 202, and a rotating member 205 is fixedly arranged inside the mounting frame 201, and the rotating member 205 is a three-phase asynchronous motor that can be reversed and electrically connected to an external power supply; the output shaft of the rotating member 205 is fixedly arranged with the other end of the elastic telescopic rod 204.

[0044] When the connecting rod 10 moves, it drives the installation frame 201 to move to the right. The installation frame 201 moves through the support block 202 to drive the welding head 203 to move until the end of the welding head 203 contacts the outer surface of the connection between the spherical tank petals. At this time, the rotating member 205 is started, and the rotating member 205 drives the elastic telescopic rod 204 to rotate around its axis. The elastic telescopic rod 204 drives the support block 202 to move around the arc-shaped side wall of the installation frame 201, thereby moving along the connection between the spherical tank petals and welding the connection.

[0045] For illustration, in the present technical solution, the transmission rod 902 contacts the blocking rod 903 only after the installation frame 201 moves out of the surface of the clamping seat 3 to prevent movement interference.
