Abstract

The utility model discloses a tool clamp for welding polar beams, which comprises two sub-clamps (1) with the same structure, a plurality of round pins (2) and two wedges (3), wherein the sub-clamps (1), the round pins (2) and the wedges (3) are independent bodies without any connection in a non-working state; this technical scheme is through setting up two J shape sub-anchor clamps, just is the C shape during the combination, and it is tight to weld the board clamp, uses the round pin to insert the locating hole and makes two sub-presss from both sides to middle indentation when pressing from both sides tightly, and the design can be applicable to not unidimensional welding board, inserts the wedge again after pressing from both sides between coupler body and the welding board, if meet crooked condition, only need strike the wedge and can revise the deformation, and then realized the purpose that welding formula limit was welded and was repaiied.

Description

Tool clamp for welding pole beam

Technical Field

The utility model relates to a welding jig field, concretely relates to frock clamp is used in utmost point roof beam welding.

Background

The existing large-scale storage tank, such as a natural gas storage tank, an oil tank and the like, is composed of a tank top, a tank wall and a tank bottom, the irrigation top is generally composed of a frame composed of a plurality of arc-shaped polar beams, and then is poured by concrete, the polar beams are formed by welding three plates, the cross sections of the polar beams are H-shaped, but bending towards two sides by taking a welding point as a center can occur in the welding manufacturing process, generally, people do not consider the problem, and do not correct the deformation of the polar beams, but consider that the deformation of several places is not considered for the large irrigation top, otherwise, once an accident occurs due to insufficient rigidity, unpredictable consequences can be brought, and the tool fixture capable of correcting the deformation while welding is designed to meet the real needs.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model aims to design a utmost point roof beam is frock clamp for welding, in order to realize this purpose, the utility model discloses a following technical scheme:

a tool clamp for welding an electrode beam comprises two sub-clamps with the same structure, a plurality of round pins and two wedges.

Furthermore, the sub-clamp is overall J-shaped, a row of positioning holes are formed in the upper end of the sub-clamp, and a hook body is arranged at the lower end of the sub-clamp.

Furthermore, the sub-clamps are symmetrically arranged in a working state, and the positioning holes in the two sub-clamps gradually tend to be concentric through the insertion of the round pins.

Furthermore, the cross section of the wedge is triangular, the wedge is placed in the hook body of the sub-clamp in a use state, and the placing directions of the two wedges are opposite.

The utility model discloses an effective fruit lies in again: through setting up two J shape sub-anchor clamps, just be the C shape during the combination, press from both sides the welding plate tightly, use the round pin to insert the locating hole and make two sub-presss from both sides to middle indentation when pressing from both sides tightly, the design can be applicable to not unidimensional welding plate, inserts the wedge again after pressing from both sides between coupler body and the welding plate, if meet crooked condition, only need strike the wedge and can revise the deformation, and then realized the purpose that the welding formula limit was welded and was repaiied.

in the figure: 1. the fixture comprises a sub-fixture, 2 round pins, 3 wedges, 4 positioning holes, 5 hook bodies and 6 workpieces.

Detailed Description

The present invention is described in detail below with reference to the attached drawings:

referring to fig. 1 to 3, the tool clamp for welding the polar beam comprises two sub-clamps (1) with the same structure, a plurality of round pins (2) and two wedges (3), wherein in a non-working state, the sub-clamps (1), the round pins (2) and the wedges (3) are independent bodies and are not connected with one another.

The sub-clamp (1) is overall J-shaped, a row of positioning holes (4) are formed in the upper end of the sub-clamp, and a hook body (5) is arranged at the lower end of the sub-clamp.

The sub-clamps (1) are symmetrically arranged in a working state, and the positioning holes (4) on the two sub-clamps (1) gradually tend to be concentric through the insertion of the round pins (2).

The cross section of the wedge (3) is triangular, the wedge (3) is placed in the hook body (5) of the sub-clamp in a use state, and the placing directions of the two wedges (3) are opposite. The using method comprises the following steps: the H-shaped polar beam is firstly spot-welded during welding, then is comprehensively welded, after spot welding is completed, two sub-fixtures (1) are used for tightly hooking workpieces (6) on two sides, then a round pin (2) is inserted into positioning holes (4) in the two sub-fixtures, so that the workpiece (6) is clamped by a hook body (5), welding can be performed after completion, a pin (3) is inserted between the hook body (5) and the workpiece (6) when the workpiece (6) deforms in the welding process, deformation can be corrected by knocking the pin (3), the pin can not be taken down temporarily after correction, and the pin can be taken down after welding is completed.

Claims
