Problems solved by technology

The utility model fixes the tank body through clamps. Although the fixation is reliable, it has the following disadvantages: one is that the clamp structure is complicated, which makes the cost of the positioning device for welding the tank high; It is installed in the jig. On the one hand, the jig needs to bear a heavy weight. On the other hand, the opening angle of the jig must be large, which further increases the equipment cost; third, because the jig needs to clamp a part of the tank, This will cause the part clamped by the fixture to be unable to be welded, so the scope of use is limited

Embodiment 2

[0042] Such as Figure 4 As shown, when different from Embodiment 1, a driving bearing 51 and a driving bearing 52 are installed under the left support frame 50, and the left supporting frame can move left and right on the base 53 through the driving bearing 51 and the driving bearing 52, and move to the desired position. Position, that is, after finding the position of the fixed tank body 54, the left support frame 50 is fixed on the base 53 by the driving positioning fixing screw clamp 55, so that the range of the tank body length that can be positioned is larger.

[0043] Such as Figure 5 As shown, it also includes a first ball bearing 57 and a first ball bearing 58 installed at the end of the piston rod 56, and a flexible suction cup 59 can be rotatably installed between the first ball bearing 57 and the first ball bearing 58 relative to the piston rod 56. The flexible suction cup 59 is fixed with the first ball bearing 57 and the first ball bearing 58 .

Embodiment 3

[0045] Such as Figure 5 As shown, the difference from Embodiment 2 is that a fourth screw driving motor 71 is installed on the fourth screw 70 , and a fifth screw driving motor 73 is installed on the fifth screw 72 .

[0046] The clamping mechanism on the right end face of the tank body includes a right support frame 74, a second threaded through hole (not shown) with a vertical straight line segment and a horizontal plane parallel to the right support frame 74, installed on the second threaded The second screw rod 76 on the through hole, two first bearings (not shown) installed on the second screw rod 76, the second screw rod drive motor 77, the lower end is installed on the second screw rod 76 and the third screw rod perpendicular to the horizontal plane 78, the upper end of the third screw rod 78 passes through the right support frame 74 and is screwed with the right support frame 74, is installed on the third screw rod 78 and is located on the third screw drive motor 79 a...

Embodiment 4

[0048] Such as Figure 6 As shown, different from Embodiment 2, the clamping mechanism on the left end surface of the tank body includes a left support frame 93, a fixed rod 91 installed on the left support frame 93, a sixth screw rod 92 whose lower end is fixed to the fixed rod 91, and a sixth screw rod 92 fixed to the fixed rod 91. The upper end of the screw rod 92 passes through the left support frame 93 and is threadedly engaged with the left support frame 93, and is installed on the sixth screw rod 92 and is positioned at the sixth adjusting handwheel 94 above the left support frame 93. The air cylinder 95 is fixed on the fixed rod 91 .

Abstract

A positioning device for a welded tank body, including a base fixed to the ground, a roller mechanism installed on the base to support the tank body, a roller driving mechanism that drives the rollers of the roller mechanism to rotate to drive the tank body to rotate, clamping from left and right directions The left end surface clamping mechanism of the tank body and the right end surface clamping mechanism of the tank body hold the tank body; the left end surface clamping mechanism of the tank body includes a left support frame fixed to the base or movable left and right relative to the base, and a cylinder installed on the left support frame , The flexible suction cup installed at the end of the piston rod of the cylinder to clamp the tank body; the advantages are high welding precision, beautiful weld seam, and not easy to damage the appearance of the tank body at the clamping position of the end surface, the tank body is beautiful, and the quality of the weld seam and the tank body are improved. The qualification rate of the tank body is high, so that the dimensional accuracy, row position tolerance and welding quality of the tank body can meet the high-quality requirements.

Description

technical field [0001] The invention relates to a positioning device for a welded tank body, in particular to a welding device for welding a tank body when the welded seam is in a straight line or a three-dimensional curved circular seam, and the end surface of the tank body is a curved surface and the side surface of the tank body is a cylindrical surface. Positioning means. Background technique [0002] For tank welding, especially for tanks that need to withstand a certain pressure, the process requirements are stricter. It is required that the dimensional accuracy, row position tolerance and welding quality of a single tank must meet certain quality requirements. Therefore, welding such tanks requires There are certain technological equipment to ensure the welding quality. When the welded seam is in a straight line, whether the weld seam can be kept on the same straight line, the key factor is whether the tank body positioning device can fix the tank body without any di...
