Welding tool clamp for large chemical container tank

Abstract

The invention relates to the technical field of chemical containers, in particular to a welding tool clamp for a large chemical container tank. The clamp comprises a clamping mechanism, a working bottom plate, a lead screw, a movable strip block, a two-way screw rod, a position adjusting motor, a fixing seat, nut seats and wedge-shaped supporting blocks; through the two-way screw rod and the two nut seats, the two wedge-shaped supporting blocks are moved inwards or outwards to proper positions, then a V-shaped groove in a proper shape is formed by the inclined end faces of the two wedge-shapedsupporting blocks, and thus container tanks with different diameters are supported; the movable strip block and parts at the upper end of the movable strip block can be moved to proper positions through the position adjusting motor and the lead screw, and thus container tanks with different lengths are supported; and then the container tanks are clamped through the clamping mechanism, and thus the container tanks with different diameters and lengths are supported and are effectively prevented from deforming, and the application range is widened.

Description

technical field [0001] The invention relates to a large-scale chemical container tank tank welding processing jig, which belongs to the technical field of chemical containers. Background technique [0002] Chemical container tanks are used to store refined chemical substances such as acids and bases, alcohols, gases, and liquids. According to different materials, there are generally: polyethylene storage tanks, polypropylene storage tanks, glass fiber reinforced plastic storage tanks, ceramic storage tanks, rubber storage tanks, stainless steel storage tanks, etc. It has excellent corrosion resistance, high strength, long life, etc. In the production process of large-scale chemical container tanks, it is necessary to weld the surface of the tank body through fixtures. At present, large-scale chemical container tank welding processing fixtures are often The V-shaped groove mechanism is used to cooperate with the clamping mechanism to support and clamp the tank body in a hori...

AI Technical Summary

Problems solved by technology

It has excellent corrosion resistance, high strength, long life, etc. In the production process of large-scale chemical container tanks, it is necessary to weld the surface of the tank through jigs. The V-shaped groove mechanism is used to cooperate with the clamping mechanism to support and clamp the tank body in a horizontal state to facilitate subsequent welding. However, the V-shaped groove mechanism is often in an integral structure, which cannot support tanks with different diameters and often needs to be replaced. The supporting mechanism will affect the scope of application. Therefore, it is necessary to design a large-scale chemical container tank welding fixture to solve the above problems
