Technical Field

[0001] The utility model relates to the field of ejection rod welding, in particular to a welding device for ejection rod production. Background Art

[0002] The catapult rod is used on the deck of a ship to lock and unlock the catapult rod when launching an aircraft. During the production of the catapult rod, multiple rods need to be welded together, which requires the use of a welding device.

[0003] Common welding devices used in ejection rod production only include a fixing function during welding, which can fix the rod body, but lack an adjustable height protection function. It cannot guarantee that the mask can be adjusted according to the height of the person during welding to prevent welding slag from splashing onto the person's face. It is easy for people of different heights to have high-temperature welding slag generated when welding the rod body splash onto the person's face. Since the height of the mask does not match the person's height, the face cannot be completely covered, causing injury and affecting safety.

[0004] Therefore, in view of the fact that the welding device for producing ejection rods lacks the protective function of adjustable height, a welding device for producing ejection rods can be designed. By pressing the drive bar, the protective mask is driven downward. At this time, the spring is squeezed and contracts. After releasing the drive bar, the drive block is pushed upward by the characteristics of the spring. The drive block drives the protective mask upward through the drive bar. After the protective mask moves to the specified position, the pin is passed through the limit hole and the drive block to fix it, ensuring that the protective mask can be adjusted according to the height of the person.

After the protective mask 6 moves to the specified position, the pin 9 is passed through the limiting hole 8 and the driving block 4 to fix it, ensuring that the protective mask 6 can be adjusted according to the height of the person, so as to solve the common welding device for ejection rod production, which only includes a fixing function during welding and can fix the rod body, but lacks a protective function with adjustable height. It cannot ensure that the mask can be adjusted according to the height of the person during welding to prevent welding slag from splashing onto the person's face. It is easy for people of different heights to have high-temperature welding slag generated when welding the rod body splash onto the person's face. Since the height of the mask does not match the person's height, the face cannot be completely covered, causing injury, affecting safety.

[0024] See also Figure 2-Figure 5In this embodiment, two fixing plates 10 are symmetrically arranged at the left and right ends of the top rear side of the workbench 1, and a semicircular groove 11 is opened in the middle of the front side of the fixing plate 10.

At this time, the spring 3 is squeezed and contracted, and after releasing the driving bar 5, the driving block 4 is pushed upward by the characteristics of the spring 3, and the driving block 4 drives the protective mask 6 to move upward through the driving bar 5. After the protective mask 6 moves to the specified position, the pin 9 is passed through the limit hole 8 and the driving block 4 to fix it, ensuring that the protective mask 6 can be adjusted according to the height of the person, and then the rod body is placed inside the semicircular groove 11. After the rod body is placed inside the semicircular groove 11, the screw rod 13 is rotated by rotating the handle 14, and the screw rod 13 pushes the semicircular The clamping plate 16 moves toward the semicircular groove 11 until the semicircular clamping plate 16 cooperates with the semicircular groove 11 to clamp the rod body. After the rod body is fixed, the rod body is welded by a welding gun. The exhaust fan 20 is started during the welding process. After the exhaust fan 20 is started, the exhaust gas generated during welding is sucked in through the air inlet groove 18. When the exhaust gas passes through the air inlet groove 18, the welding slag is filtered through the filter mesh 19, thereby preventing the welding slag from entering the interior of the exhaust fan 20 and causing damage to it. The exhaust fan 20 discharges the inhaled exhaust gas into the interior of the filter box 21, filters the exhaust gas through the activated carbon filter plate 22, and then discharges it through the outlet pipe 23, realizing an adjustable height protection function.
