Description

Technical Field

[0001] The utility model relates to the field of product welding, and more specifically, it relates to a jacking device based on anti-deformation. Background Technique

[0002] Welding of workpieces is an important metal connection process, which is usually used in the fields of manufacturing machinery, building structures, automobiles, ships, etc. During the welding process, by heating or pressurizing, the metal surface of the workpiece reaches the melting or plastic state, and then a firm connection is formed after cooling. Common welding methods include arc welding, gas shielded welding, resistance welding, etc. Arc welding uses the high temperature generated by the arc to locally melt the welding rod and the workpiece, so as to achieve connection. Gas shielded welding prevents oxidation of the welding area through the shielding gas, improving the welding quality. Resistance welding uses the resistance heat generated when the current passes through the workpiece for welding. Before welding, it is necessary to clean the workpiece, prepare suitable welding materials and equipment, and select appropriate welding methods and parameters according to the material and requirements of the workpiece. Attention should be paid to safety during the welding process to avoid the hazards of electric shock, fire and harmful gases. After welding, it is also necessary to inspect and process the weld to ensure that the welding quality meets the requirements.

[0003] However, for the existing welding devices, during the welding process, the arc force and droplet impact force may cause local depression or protrusion of the metal material at the welding part for easily deformable products, especially more obvious in thin plate welding or thin-walled structure welding, destroying the original flatness.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a jacking device based on anti-deformation. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present utility model is to provide a jacking device based on anti-deformation.

[0006] To achieve the above purpose, the present utility model provides the following technical solution: A jacking device based on anti-deformation, including a bracket and a support table located at the top of the bracket. A through hole is opened on the tabletop of the support table. An air jack is installed at the position directly below the through hole on the bracket. The top end of the air jack is installed with a jacking rod that extends out of and retracts into the through hole. An air compressor for inflating the inside of the air jack is also installed at the top end of the bracket.

[0007] Preferably, the air compressor is interconnected with the air jack through a connecting hose.

[0008] Preferably, a valve is installed at the air outlet end of the air compressor, and the end of the valve is interconnected with the head of the connecting hose, which can meet the strict requirements for the pressure rising speed of the air jack under different working conditions.

[0009] Preferably, the end of the connecting hose is sleeved on the air inlet nozzle of the lifting airbag and fixed by a clamp, so that the connecting hose and the lifting airbag can be quickly installed and removed.

[0010] Preferably, the air compressor is detachably connected to the bracket and can be disassembled for repair in case of damage.

[0011] Preferably, a convex block is fixedly connected to the surface of the bracket, and a mounting block is fixedly connected to the bottom end of the air compressor. A convex groove matching the convex block is provided at the bottom of the mounting block. This installation method of first limiting and then fixing is more convenient for tooling personnel to operate.

[0012] Preferably, screw holes are provided on both sides of the bottom end of the convex block, and through holes are provided on both sides of the bottom end of the mounting block. Screws are installed at the openings of the through holes, and the screws are successively passed upward through the through holes and then rotated clockwise to be installed in the screw holes, and the convex block and the mounting block are fixed together by the screws.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 2. A valve is installed on the gas delivery end of the air compressor of the utility model, which can provide more precise flow regulation and can adjust the air intake speed to a very accurate degree according to actual needs, meeting the strict requirements on the pressure rise speed of the lifting airbag under different working conditions;

[0025] like Figures 1-5 As shown, the utility model provides a lifting device based on reverse deformation, including a bracket 1, and a support platform 2 located on the top of the bracket 1, a through hole 3 is opened on the surface of the support platform 2, a lifting airbag 4 is installed on the bracket 1 just below the through hole 3, a lifting rod 5 extending from and retracting into the through hole 3 is installed on the top of the lifting airbag 4, and an air compressor 6 for inflating the inside of the lifting airbag 4 is also installed on the top of the bracket 1.

[0026] When in use, gas is filled into the lifting airbag 4 through the air compressor 6 to make it expand, thereby driving the lifting rod 5 thereon to move upward. The lifting rod 5 passes through the through hole 3 at the top of the support platform 2 (the lifting rod 5 can be limited by the through hole 3), thereby supporting the welding part of the workpiece fixed to the support platform 2. When the welded product is subjected to the arc force and the impact force of the molten droplet during the welding process, the lifting airbag 4 is used to offset the deformation force, so that a good flatness can be maintained after the welding is completed.

[0027] It should be noted that during the welding process, the air compressor 6 needs to continuously inflate the jacking airbag 4. This is because as the welding process progresses, the deformation trend of the workpiece may change continuously. Continuous inflation can ensure that the jacking airbag 4 always provides a stable counter-deformation force to effectively offset the deformation force generated by welding, ensuring that the workpiece can maintain good flatness and shape after welding is completed.

[0028] Furthermore, a valve 8 is installed at the air delivery end of the air compressor 6. The end of the valve 8 is interconnected with the head of the connecting hose 7. The air compressor 6 can usually only roughly adjust the output air volume and pressure within a certain range and it is difficult to achieve very precise speed control. However, the valve 8 can provide more precise flow regulation and can adjust the intake speed to a very accurate level according to actual needs, meeting the strict requirements for the pressure rising speed of the jacking airbag 4 under different working conditions.

[0029] The air compressor 6 is detachably connected to the bracket 1. In this way, when the air compressor 6 is damaged, it is convenient to disassemble it for repair or replacement. The following is the specific detachable structure: A convex block 9 is fixedly connected to the surface of the bracket 1, and an installation block 10 is fixedly connected to the bottom end of the air compressor 6. A convex groove 11 adapted to the convex block 9 is provided at the bottom of the installation block 10. Threaded holes 12 are provided on both sides at the bottom end of the convex block 9, and through holes 13 are provided on both sides at the bottom end of the installation block 10. Screws 14 are installed at the opening parts of the through holes 13, and the screws 14 sequentially pass through the through holes 13 upward and then are screwed into the threaded holes 12 in the clockwise direction. During installation, the connecting hose 7 on the air compressor 6 is hermetically connected to the air inlet nozzle of the jacking airbag 4. Then, the installation block 10 at the bottom of the air compressor 6 is slid into the convex block 9 through its convex groove 11 for positioning. After the sliding is completed, the threaded holes 12 and the through holes 13 are exactly aligned, and the installation block 10 can be fixed to the convex block 9 by screwing the screws 14 through the through holes 13 and then into the threaded holes 12 in the clockwise direction, thus installing the air compressor 6 on the bracket 1. This installation method of first positioning and then fixing does not require the operator to hold by hand when installing the screws 14, making it more convenient for the tooling personnel to operate. Similarly, during disassembly, only the connection between the connecting hose 7 and the jacking airbag 4 needs to be disconnected, the screws 14 are removed, and the installation block 10 is slid off the convex block 9 to realize the disassembly of the air compressor 6. The disassembly and assembly are very convenient.

[0030] The present utility model also provides the connection method between the connecting hose 7 and the air inlet nozzle of the jacking airbag 4, that is, the end of the connecting hose 7 is sleeved on the air inlet nozzle of the jacking airbag 4 and fixed by a clamp. In this way, it can be quickly installed and disassembled. The clamp can be quickly loosened by rotating the nut on the clamp, and the disassembly between the connecting hose 7 and the jacking airbag 4 can be completed. For installation, similarly, the connecting hose 7 is sleeved on the air inlet nozzle of the jacking airbag 4, and then the nut on the clamp is tightened to complete the sealing connection between the two.

[0031] The above are only the preferred embodiments of the present utility model, and do not impose any formal restrictions on the present utility model; any ordinary technician in the industry can smoothly implement the present utility model as shown in the accompanying drawings of the specification and as described above; however, any minor changes, modifications, and equivalent variations made by those skilled in the art within the scope of the technical solution of the present utility model by using the technical content disclosed above are all equivalent embodiments of the present utility model; at the same time, any equivalent changes, modifications, and evolutions made to the above embodiments based on the essential technology of the present utility model still fall within the protection scope of the technical solution of the present utility model.
