Abstract

The invention discloses a novel automatic welding inner-supporting device for circular seams of tube sections of a storage box. The novel automatic welding inner-supporting device comprises a main shaft which is vertically arranged, and further comprises a horizontal flower disc, wherein the middle part of the flower disc is fixedly connected with the main shaft through a bushing; a plurality of long linear guide rails and a plurality of short linear guide rails are arranged in the radial direction on the upper surface of the flower disc; the long linear guide rails and the short linear guiderails are alternatively arranged and are uniformly distributed in the peripheral direction; the long linear guide rails are connected with an inner arc-shaped supporting block through slide blocks; the short linear guide rails are connected with an outer arc-shaped supporting block through slide blocks; and when inner and outer arc-shaped supporting blocks outwards slide to theoretical working positions along the guide rails, the arc-shaped surface of the inner arc-shaped supporting block and the arc-shaped surface of the outer arc-shaped supporting block can be spliced into a complete circumference. The novel automatic welding inner-supporting device is especially suitable for welding forming use of the tube sections of the storage box, adopts an air cylinder to provide power, adopts theflower disc to support, has enough structural strength and rigidity, and meets clamping positioning needs of an automatic welding process for the circular seams of the tube sections of the storage box.

Description

technical field

[0001] The invention relates to an inner support device, in particular to an inner support device for automatic welding of the circular seam of the barrel section of a storage tank. Background technique

[0002] The storage tank is a box body assembled and welded by several barrel sections and two box bottoms. The traditional manual welding production mode has been unable to meet the demand due to high labor intensity and low production efficiency. Therefore, the factory has launched an automatic storage tank Welding process research. In order to ensure the smooth progress of the tank automatic welding process test and subsequent product production tasks, the factory purchased the tank girth automatic welding equipment developed by a domestic manufacturer.

[0003] During the automatic welding process of the girth seam of the storage tank section, because the product welding seam is far away from the clamping end face of the equipment, objectively there is a...

Examples

Embodiment 1

[0033] Example 1: see Figure 1 to Figure 15 ,in, figure 1 It is a structural schematic diagram of the present invention when it is used, and it is used for automatic welding of the girth seam of the barrel section of the storage tank.

[0034] An automatic welding internal support device for the circular seam of the tank barrel section, including a vertically arranged main shaft, and a horizontal faceplate 2, the middle part of the faceplate 2 is fixedly connected to the main shaft through a bushing 13,

[0035] The upper surface of the faceplate 2 is provided with several long linear guide rails 7 and several short linear guide rails 3 along its radial direction, and the long linear guide rails 7 and short linear guide rails 3 are staggered and evenly distributed.

[0036] The long linear guide rail 7 is connected to an inner arc-shaped support block 6 through a slider, the end of the inner arc-shaped support block 6 away from the main shaft is an arc-shaped surface, the bo...
