Description

Technical Field

[0001] The utility model belongs to the technical field of brazing equipment, in particular to an integrated automatic brazing machine for copper-aluminum welding. Background Art

[0002] Brazing machine is a kind of equipment for welding metals. Brazing machine completely replaces traditional brazing equipment. It is a new generation of brazing equipment that does not require flammable gas. Traditional electric welding machines use acetylene and other gases for welding, while brazing machine adopts IGBT inverter control principle. During welding, the flame is very stable. The whole equipment is light and convenient, suitable for outdoor welding, and only electricity is needed. The advantages of brazing machine are very obvious. Brazing machine is more common in metal processing places in factories. There are many types of brazing machines at present, which are more common equipment among welding equipment.

[0003] A Chinese authorized document with application number CN 111001893 A discloses a split automatic brazing machine. In order to solve the problems that the limiting and fixing of the welded parts during welding is not complete, the welding error is large, and the temperature during welding is high, and the welded parts are not completely limited, which easily leads to deformation of the welded finished product, a split automatic brazing machine is proposed, including a bottom plate and a protective cover, the protective cover is fixed to the top of the bottom plate, a first welding bin and a second welding bin are arranged side by side on the front of the protective cover, the first welding bin and the second welding bin are both provided with movable plates, the bottom ends of the two movable plates are both provided with driving mechanisms, the first welding bin is provided with a first fixing mechanism, and the bottom end of the first fixing mechanism is fixedly connected to the top of the movable plate.

[0004] In the above scheme, the semi-cylindrical support rod and the limiting plug are used to perform preliminary limiting on the rolling plate shell, the rotating plate is pulled and rotated 180 degrees to allow the fixed plug to rest on the surface of the fixed platform for limiting and fixing, so that the rolling plate shell can be sleeved inside the slot, and the circumference of the rolling plate shell can be effectively limited. There are the following problems. First, the rolling plate shell can be sleeved inside the slot, and there is only one slot and no slot on the other side. When welding, the force will be uneven, so that the other side will bounce open or have a gap. The contact of the rolling plate shell at the connection on both sides is not firm, which can easily cause the equipment after welding to have defective products, affecting the quality of product production; second, the use of limiting plugs to fix one side of the rolling plate shell requires opening a hole in the rolling plate shell, and it is more troublesome to close the hole later.

By setting the connecting block 201 and the limiting block 202, the limiting block 202 is utilized to control the moving position of the connecting block 201 to prevent the connecting block 201 from rotating, so that when the first threaded rod 17 rotates, the moving block 203 is driven to move horizontally instead of rotating.

During the initial clamping, one of the fixed bases 305 can be lowered to the lowest position, so that the bottom rotating block 304 contacts the pressing block 11, so as to limit the position of the material, so that the end of the material is against the fixed base 305, and then the other fixed base 305 is used for fixed clamping.

[0034] like Figures 1 to 8 As shown, the internal thread of the connecting block 201 is connected to the first threaded rod 17, the top of the moving block 203 is fixedly connected to the clamping block 13, the inside of the circular groove 204 is provided with the first threaded rod 17, the inner surface of the connecting seat 301 is fixedly connected to the pressing block 11, the outer surface of the second threaded rod 302 is movably sleeved with a fixed base 305, the clamping pad 306 is made of rubber material, the bottom of the clamping pad 306 is provided with an anti-slip groove, the bottom of the clamping pad 306 is movably connected to the support rod 10, and by providing the clamping pad 306, it is convenient to clamp and fix the material, thereby preventing it from slipping, facilitating subsequent operations, and facilitating later disassembly.

[0035] like Figures 1 to 8As shown, a mounting groove 12 is provided inside the pressing block 11, and the mounting groove 12 is matched with the clamping block 13. The outer surface of the pressing block 11 is arc-shaped, there are two clamping mechanisms 3, and there are eight moving mechanisms 2.

There are two first support plates 5, and the motor box 7 is located in the middle of the two first support plates 5. By setting the pressing block 11 and the clamping block 13, the pressing block 11 is installed on the clamping block 13 by utilizing the mounting groove 12, so that the user can replace the pressing block 11 conveniently, thereby realizing the production of compressor housing components for air conditioners with different inner diameters. By setting the pressing block 11, the surface of the pressing block 11 is set to an arc shape, so that the rolling plate shell forms a circle, so that it fits tightly and is fixed more firmly, preventing it from accidentally falling off, and facilitating processing.

[0036] The working principle and use process of this utility model:

[0037] During operation, the user installs the equipment inside the first welding bin and removes the original fixing device therein. After the installation is completed, the equipment is powered on. Then, according to the inner diameter of the air-conditioning compressor housing assembly to be processed, the pressing block 11 with different curvatures is selected, and then the pressing block 11 is installed on the clamping block 13 through the clamping block 13. Then, the plate rolling shell is clamped into the inside of the clamping mechanism 3 so that it is fixed to one side of the plate rolling shell, thereby avoiding the operation of opening a hole in the plate rolling shell. The knob 303 is turned to drive the second threaded rod 302 to rotate, so that the second threaded rod 302 moves up and down, and then drives the rotating block 304 to move, and then controls the up and down movement of the fixed base 305, so as to achieve the clamping and fixing of the material. Two fixed bases 305 are arranged inside a clamping mechanism 3. During the initial clamping, one of the fixed bases 305 can be lowered to the lowest position so that the bottom rotating block 304 contacts the pressing block 11, thereby limiting the material so that the end of the material is on the fixed base 305, and then the other fixed base 305 is used. A fixed base 305 is used for fixed clamping. After the clamping mechanisms 3 are provided on both sides of the material for fixing, the material is rotated so that the other side is also stuck in the inside of the clamping mechanism 3, and then the transmission shaft 14 is driven to rotate by the motor inside the motor box 7, thereby driving the first bevel gear 15 to rotate, and then driving the second bevel gear 16 to rotate, so that the first threaded rod 17 is rotated, and the moving mechanism 2 is controlled to move outward, and the limit block 202 is used to control the moving position of the connecting block 201 to prevent the connecting block 201 from rotating, so that when the first threaded rod 17 rotates, the moving block 203 is driven to move horizontally instead of rotating, and the moving mechanism 2 moves outward, driving the pressing block 11 to move, so as to fully contact with the inside of the rolling plate shell, and then fix it firmly, control its shape, and push the second set of discs 18 to move under the action of the electric telescopic rod 4, so that the material is inside the second set of discs 18 and the first set of discs 8 to prevent it from bouncing, and then welded by the brazing machine head.
