Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary tools for welding, and particularly relates to a quick installation fixture for FAB welding backing pads and an installation method thereof. Background Art

[0002] FAB welding is mainly applied to the longitudinal welds of the inner bottom and deck of the ship's cargo hold. During welding, a backing pad needs to be installed on the back of the weld to prevent the high-temperature liquid metal formed during welding from flowing under the action of gravity, so that the back of the weld is well formed and a uniform and beautiful weld shape is obtained.

[0003] In production practice, due to the inconsistent ship types, the distance between the position where the backing pad is pasted and the standing surface of the personnel is often large. It is necessary to use an aluminum ladder or other climbing fixtures to complete the pasting, and the aluminum ladder needs to be continuously moved back and forth, resulting in a large labor intensity. Summary of the Invention

A support rod is provided at the head end of the lifting plate, and a positioning anti-slip magnet is provided at the tail end of the lifting plate; the FAB welding backing pad includes a backing block and an aluminum foil tape. A lifting groove is provided at the top of the lifting plate, the backing block is placed in the lifting groove, and the backing block is in contact with the groove wall of the lifting groove. The aluminum foil tape is located outside the lifting groove; the lifting plate is provided with a sliding pressing rod, and the sliding pressing rod can slide along the length direction of the lifting plate; a pressing roller is provided at the upper end of the sliding pressing rod, and the pressing roller is in pressure contact with the aluminum foil tape. The pressing rollers are arranged on both sides of the lifting plate.

[0007] Preferably, the sliding pressing rod is set to be T-shaped. The sliding pressing rod includes a vertical pressing rod and a horizontal pressing rod; the lifting plate is provided with a long strip-shaped sliding hole, and both ends of the horizontal pressing rod are movably inserted through the sliding hole. The end of the horizontal pressing rod passing through the sliding hole is provided with a pressing roller. Hold the sliding pressing rod and slide it along the sliding hole, so as to realize the rolling pressure of the pressing roller on the aluminum foil tape.

[0008] Preferably, the vertical cross-section of the lifting plate is H-shaped. The lifting plate includes two vertical plates and a horizontal plate, and the horizontal plate is the bottom of the lifting groove; the part of the vertical plate below the horizontal plate is provided with a sliding hole.

[0009] Preferably, the positioning and anti-slip magnet is fixed on the cross plate of the lifting plate, and the positioning and anti-slip magnet contacts and positions one end of the cushion block. The positioning and anti-slip magnet is installed at the tail end of the lifting plate, and it has two main functions: one is to position and stop the tail end of the FAB welding gasket when the FAB welding gasket is temporarily placed in the lifting plate, and the other is to adsorb on the steel plate to temporarily replace the sliding pressing rod after the lifting and positioning is completed, playing the role of temporarily fixing the tail end of the lifting plate.

[0010] Preferably, a centering cut is provided in the middle of the head end of the lifting plate and the middle of the tail end of the lifting plate. The centering cut is set in a V shape, and the positioning and anti-slip magnet is arranged close to the centering cut. The centering cut is set in a V shape to facilitate centering with the weld seam.

[0011] Preferably, the support rod is hinged to the lifting plate.

[0012] Preferably, a rubber layer is provided on the outer periphery of the pressing roller.

[0013] An installation method of a quick installation fixture based on an FAB welding gasket includes the following steps:

[0014] (1) Slide the sliding pressing rod to the tail end of the lifting plate;

[0015] (2) After removing the protective film on the back of the aluminum foil tape, place the cushion block in the lifting groove, and one end of the cushion block contacts and positions with the positioning and anti-slip magnet;

[0016] (3) Hold the support rod and the sliding pressing rod to lift the lifting plate, so that the lifting plate approaches the weld seam;

[0017] (4) According to the centering cuts at the head end and the tail end of the lifting plate, align the centering cuts with the weld seam;

[0018] (5) The lifting plate presses against the steel plate where the weld seam is located, and the positioning and anti-slip magnet is attracted to the steel plate to realize the positioning of the tail end position of the lifting plate;

[0019] (6) Keep the support rod pressing against the steel plate, and then drive the sliding pressing rod to slide towards the head end of the lifting plate, and the pressing roller rolls the aluminum foil tape;

[0020] (7) Continue to drive the sliding pressing rod to slide towards the tail end of the lifting plate, so that the pressing roller rolls back and forth along the aluminum foil tape once, and the aluminum foil tape adheres firmly to the steel plates on both sides of the weld seam;

[0021] (8) Hold the support rod and the sliding pressing rod by hand, and pull down the lifting plate at the same time to remove the lifting plate. Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. The present invention can attach the FAB welding gasket to the steel plates on both sides of the weld seam by using an installation jig, without the need to use an elevated jig. The operators can work on the ground, improving the operation safety.

[0023] 2. The present invention first performs lifting and positioning, and then by pushing and pulling the sliding pressing rod, the pressing roller reciprocally rolls on the aluminum foil tape, realizing the tight attachment between the FAB welding gasket and the steel plates on both sides of the weld seam. One operator can perform the attachment of the FAB welding gasket, with simple operation and greatly reducing the labor intensity of the operators.

[0024] 3. The overall design of the present invention is simple, the jig is lightweight, low-cost, and has practicality. BRIEF DESCRIPTION OF THE DRAWINGS
