Problems solved by technology

[0004] However, in the above-mentioned girth welding equipment, the cylinder or pipe fittings are usually placed horizontally, and then the cylinder is rotated and welded by the rotary displacement mechanism. The circle calibration of the cylinder needs to be done manually, and the appearance of the product after calibration Not very beautiful, and the workload of the workers is relatively large

Embodiment Construction

[0022] Specific embodiment 1 of the present invention, as figure 1 As shown in the figure, a tooling for cylinder ring seam assembly includes a frame 1, an oil tank for the entire hydraulic system of the tooling can be installed inside the frame 1, and a vertical rotating shaft 10 is installed on the frame 1, such as image 3 As shown, a horizontally arranged working platform 2 is installed on the rotating shaft 10. The working platform 2 is driven by a main driving device and can rotate around a vertical rotating shaft. The main driving device includes a motor 7 installed on the working platform 2 , a pinion 11 is installed on the rotating shaft of the motor, the pinion 11 is located on the underside of the working platform 2, and meshes with the large gear 9 fixed on the frame 1, as figure 2 , image 3 and Figure 4 shown. A lifting device is installed on the working platform 2. The lifting device in this example is an oil cylinder 5 installed on the working platform 2. ...

Abstract

The invention discloses a fixture used in combination of circular seams of a cylinder. The fixture comprises a frame, and is characterized in that the frame is equipped with a horizontal working platform; the working platform is driven by a main drive unit and can rotate around a rotating shaft in the vertical direction; and an elevating device is arranged on the working platform and is equipped with not less than 8 pushing devices which are positioned in the same horizontal plane and are uniformly distributed along the circumferential direction. The fixture has the beneficial effects that quick up-down devices can complete combination within 30 seconds at a high speed, and quick support devices can reach the desired effect within about one minute; by the adoption of the fixture, the cylinder with poor ellipticity can be automatically rounded, and the time for dealing with alignment tolerance and appearance of the circular seams can be saved; in addition, practical inspection proves that circular seam combination time can be reduced by one than half by adopting the fixture.

Description

technical field [0001] The invention relates to a frock for pairing circular seams of cylinder bodies. Background technique [0002] In the prior art, the pair assembly and welding of the cylinder part of the pressure vessel is usually carried out by using simple pair tooling. During the pair assembly process, it is necessary to manually correct the circle of the circular seam, and then pair weld. [0003] Due to the large workload and low efficiency of manual calibration and welding in the process of circular seam grouping, and the appearance of the product often leaves defects during the circular seam grouping process, therefore, in the prior art, the circular seam grouping equipment of the cylinder is carried out. Improvements have been made. For example, Chinese invention patent 200710023268.7 discloses a large-scale pipe girth welding positioner, which includes a frame body, a rotary displacement mechanism rotatably arranged on the frame body, and a rotary displacement ...
