Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a fixing support assembly for welding a ceramic liner. Background Art

[0002] Ceramic welding backings are suitable for welding processes in a variety of industries, including shipbuilding, bridges, boilers, pressure vessels, and steel structures. Existing adhesive ceramic welding backings are suitable for single-sided welding of general structural steel and common low-alloy structural steel in horizontal, vertical, and horizontal positions, and are easy to use. When using ceramic welding backings, the backing must be placed at the joint to be welded and then secured to the metal block using adhesive strips. However, in high humidity, the adhesive strips may lose their viscosity, preventing the backing from being effectively fixed to the metal block. Utility Model Content

[0003] The purpose of the present invention is to provide a reasonably designed fixing support assembly for ceramic liner welding in view of the defects and shortcomings of the prior art, which can solve the above-mentioned defects.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical solution: it comprises two fixed blocks with identical structures and symmetrically arranged, the tops of the opposite surfaces of the two fixed blocks are respectively provided with fixed grooves, elastic distance adjustment structures are installed in the two fixed blocks, and a magnetic adsorption component is installed on each fixed block.

[0005] Preferably, the elastic distance adjustment structure includes a sliding groove provided in the fixed block, a sliding rod is slidably installed in the sliding grooves relative to the two fixed blocks, and limit blocks are provided at both ends of the sliding rod; an adjustment groove is provided on the inner side of the fixed block, and the adjustment groove is coincident with the axial center line of the sliding groove, a tension spring is provided in the adjustment grooves of the two fixed blocks, and the two ends of the tension spring are respectively connected to the inner walls of the adjustment grooves of the two fixed blocks, and the tension spring is sleeved on the outer side of the sliding rod.

[0006] Preferably, the magnetic adsorption component includes a magnet block inserted in the fixed block, the magnet block is a permanent magnet, and a heat insulation wrapping layer is provided between the outer side of the magnet block and the fixed block.

[0007] Preferably, the thermal insulation wrapping layer is an alumina ceramic wrapping layer.

[0008] Preferably, the fixing block is made of copper plate.

[0009] Preferably, the fixing block is provided with anti-slip grooves.

[0010] After adopting the above structure, the beneficial effects of the utility model are:

[0011] 1. This device is equipped with a slide groove and a sliding rod. By pulling the fixed blocks to both sides, the tension spring is stretched to generate elastic force, so that the ceramic liner can be placed in the fixed groove. After releasing the hand, the tension spring rebounds, which can drive the two fixed blocks to move toward each other, clamping and fixing the ceramic liner. The installation is convenient and quick.

[0012] 2. This device can use magnetic attraction to adsorb the support component and ceramic liner to the steel plate by setting a magnet block, thereby achieving fixation. The fixing effect is stable and is not affected by humidity and surface pollution of the steel plate. No glue is required and there is no residue after disassembly.

[0013] 3. This device uses an alumina insulation wrapping layer that can effectively insulate, thereby reducing the impact of heat on the magnet block. The copper fixing block is heat-resistant, and copper itself is non-magnetic and will not affect the magnetic force of the magnet block. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See Figure 1-Figure 3 As shown, it comprises two fixed blocks 1 with identical structures and symmetrical arrangement, the tops of the opposite surfaces of the two fixed blocks 1 are respectively provided with fixing grooves 2, elastic distance adjustment structures are installed in the two fixed blocks 1, and a magnetic adsorption component is installed on each fixed block 1.

[0021] See Figure 1-Figure 2As shown, the elastic distance adjustment structure includes a slide groove 4 opened in the fixed block 1, and a sliding rod 5 is slidably installed in the slide grooves 4 relative to the two fixed blocks 1, and a limit block 6 is provided at both ends of the sliding rod 5; an adjustment groove 7 is opened on the inner side of the fixed block 1, and the adjustment groove 7 is coincident with the axial center line of the slide groove 4, and a tension spring 8 is provided in the adjustment groove 7 of the two fixed blocks 1, and the two ends of the tension spring 8 are respectively connected to the inner walls of the adjustment groove 7 of the two fixed blocks 1, and the tension spring 8 is sleeved on the outer side of the sliding rod 5.

[0022] As an optimization solution of the present invention, a slide groove 4 and a sliding rod 5 are provided, which can pull the fixed block 1 to both sides, so that the tension spring 8 is stretched to generate elastic force, so that the ceramic liner can be placed into the fixed groove 2. After releasing the hand, the tension spring 8 rebounds, which can drive the two fixed blocks 1 to move toward each other, clamping and fixing the ceramic liner.

[0023] See Figure 1-Figure 2 As shown, the magnetic adsorption component includes a magnet block 9 inserted into the fixed block 1. The magnet block 9 is a permanent magnet. A heat insulation wrapping layer 10 is provided between the outer side of the magnet block 9 and the fixed block 1.

[0024] As an optimization solution of the present invention, by providing a magnet block 9, the support assembly and the ceramic liner can be adsorbed onto the steel plate by magnetic attraction, thereby achieving fixation without the need for glue.

[0025] See Figure 1-Figure 2 As shown, the heat-insulating wrapping layer 10 is an alumina ceramic wrapping layer; the fixing block 1 is made of a copper plate; and the fixing block 1 is provided with anti-slip grooves 3.

[0026] As an optimization solution of the present invention, the thermal insulation wrapping layer 10 made of alumina can effectively insulate, thereby reducing the impact of heat on the magnet block 9. The fixed block 1 made of copper is heat-resistant, and copper itself is not magnetic and will not affect the magnetic force of the magnet block 9. The anti-slip grooves 3 can ensure that the fixed block 1 will not slide after installation.

[0027] The use process of this utility model:

[0028] First, pull the fixing block 1 to both sides, and then put the ceramic liner to be used into the fixing groove 2. After loosening the fixing block 1, the tension spring 8 drives the two fixing blocks 1 to rebound and clamp the liner. Then, move the support assembly to the position of the steel plate to be welded, align the liner with the gap to be welded, and gradually push the support assembly close to the steel plate. When the distance is close enough, suction is generated between the magnet block 9 and the steel plate, and the support assembly can be fixed to the steel plate, and then welding can begin.

[0029] After the welding is completed and the temperature drops, the worker can remove the support assembly and ceramic liner and use them again.
