Description

Technical Field

[0001] This application relates to the field of fuel tank processing technology, specifically a positioning tooling for reducing thermal deformation during fuel tank welding. Background Technology

[0002] Fuel tanks are containers used to carry fuel in aircraft or automobiles, and are specialized containers for storing hydraulic oil or hydraulic fluid in hydraulic systems. Fuel tanks can be divided into open and closed types. During processing or repair, fuel tanks are welded using a welding machine, and a positioning structure is used to fix the tank in place during welding. During welding, the inner side of the fuel tank is prone to deformation. However, existing positioning fixtures can only fix the position of the tank and cannot support the deformation of the inner side, leading to deformation of the inner side of the tank.

[0003] Therefore, there is an urgent need for a positioning fixture that can reduce the thermal deformation of the oil tank during welding, in order to solve the problem of easy deformation of the inner side of the oil tank. Utility Model Content

This fixture offers the advantage of providing stable support for the oil tank welding points and solves the problem of easy deformation of the inner side of the oil tank.

[0005] To achieve the above objectives, this application provides the following technical solution: a positioning fixture for reducing thermal deformation during welding of fuel tanks, comprising a welding machine, a support column, and a welding head, wherein the support column is rotatably connected to the inside of the welding machine, the welding head is installed inside the welding machine, a positioning mechanism is provided on the back side of the welding machine, and a fixing mechanism is provided on both sides of the welding machine;

The electric cylinder one is installed on the back side of the welding machine, the support rod is installed on the back side of the welding machine, and the other end of the support rod is fixedly connected to the back side of the support block by screws. The electric cylinder two is installed in the groove at the bottom of the support block. One end of the connecting rod one is fixedly connected to the output end of the electric cylinder two, and the other end of the connecting rod one is fixedly connected to the bottom of the support plate by screws.

[0007] By adjusting the position and height of the support plate, it can be pressed tightly against the welding point inside the fuel tank, making the inside of the welding point less prone to deformation and improving the quality of the fuel tank.

[0008] Preferably, a support sleeve is slidably connected to the outer surface of the support rod, the support sleeve is fixedly connected to the plate on the back side of the welding machine, and the connecting rod is rotatably connected to the support block through a bearing.

[0009] Preferably, the outer side of the support rod is provided with four sets of square protrusions, and the inner side of the support sleeve is provided with a groove that matches the support rod.

[0010] Preferably, the support sleeve is connected to the welding machine by screws.

[0013] In summary, this application includes at least one of the following beneficial effects:

[0014] 1. This positioning fixture reduces thermal deformation during fuel tank welding. During welding, the fuel tank can be placed on a support column.

[0015] 2. This positioning fixture for reducing thermal deformation during oil tank welding can adjust the extension length of connecting rod 2. When connecting rod 2 extends, it drives the pressure block to press against both sides of the oil tank.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Please see Figure 1-5 A positioning fixture for reducing thermal deformation during welding of fuel tanks includes a welding machine 1, a support column 2, and a welding head 3. The support column 2 is rotatably connected to the inside of the welding machine 1 and can rotate inside the welding machine 1 to facilitate the movement of the fuel tank. The welding head 3 is installed inside the welding machine 1 and its position can be moved to weld different positions on the fuel tank. A positioning mechanism is provided on the back side of the welding machine 1, and fixing mechanisms are provided on both sides of the welding machine 1.

[0024] Specifically, the positioning mechanism includes a support plate 211, a support rod 112, a support block 114, a second electric cylinder 115, a first connecting rod 116, and a support plate 117. The first electric cylinder 111 is installed on the back side of the welding machine 1, and the support rod 112 is installed on the back side of the welding machine 1. The other end of the support rod 112 is fixedly connected to the back side of the support block 114 by screws. A support sleeve 113 is slidably connected to the outer surface of the support rod 112, and the support sleeve 113 is fixedly connected to the plate on the back side of the welding machine 1. Four sets of square protrusions are provided on the outer side of the support rod 112. The inner side of the support sleeve 113 is provided with a groove that matches the support rod 112. The support sleeve 113 is connected to the welding machine 1 by screws. The connecting rod 116 is rotatably connected to the support block 114 by bearings. The electric cylinder 115 is installed in the groove at the bottom of the support block 114. One end of the connecting rod 116 is fixedly connected to the output end of the electric cylinder 115, and the other end of the connecting rod 116 is fixedly connected to the bottom of the support plate 117 by screws.

[0025] With the above technical solution, the fuel tank can be placed on the support column 2 during welding. Electric cylinder 111 is activated, and it moves the support block 114 via the support rod 112. The support rod 112 slides inside the support sleeve 113 when it extends or retracts. By adjusting the position of the support block 114, it moves the support plate 117 via the connecting rod 116. Electric cylinder 115 is then activated, and it moves the support plate 117 up and down via the connecting rod 116. By adjusting the position and height of the support plate 117, it can be pressed against the welding point inside the fuel tank, making the inner side of the welding point less prone to deformation and improving the quality of the fuel tank.

[0026] Specifically, the fixing mechanism includes a support plate 211, an electric cylinder 212, a connecting rod 213, and a pressure block 214. The support plate 211 is welded to both sides of the welding machine 1. The electric cylinder 212 is installed on the outside of the support plate 211. One end of the connecting rod 213 is fixedly connected to the output end of the electric cylinder 212, and the other end of the connecting rod 213 is fixedly connected to the outside of the pressure block 214 by screws. The pressure block 214 has a circular slot on its inner side.

[0027] With the above technical solution, the oil tank can be placed on the support column 2 during welding. The electric cylinder 212 is started, and the electric cylinder 212 drives the pressure block 214 to move through the connecting rod 213. By adjusting the extension length of the connecting rod 213, the connecting rod 213 extends and drives the pressure block 214 to press the two sides of the oil tank. By adjusting the extension length of the two sets of connecting rods 213, the two sets of pressure blocks 214 cooperate to push the oil tank to move on the support column 2, so that the positioning fixture can easily adjust the position of the oil tank and make the positioning fixture easy to use.

[0028] During use, by adjusting the position and height of the support plate 117, the support plate 117 can be pressed against the welding point inside the oil tank, making the inside of the welding point less prone to deformation and improving the quality of the oil tank.
