Embodiment Construction

[0013] Depend on figure 1 with figure 2 As shown, a workbench 5 and its lifting device are arranged below the frame 1, and the lifting device is composed of a motor 61, a worm gear reducer 62, a screw 63, a guide rod 65, and a slider 64, and the screw rod 63 and the guide rod 65 are vertically arranged , the slider 64 is fixed on one side of the workbench 5, and the slider 64 has an internal thread that matches the screw mandrel 63 and a vertical guide hole that matches the guide rod 65. When the motor 61 is driven, the screw mandrel 63 is driven by the worm gear reducer 62 Rotate so that the slide block 64 on the screw mandrel 63 moves vertically along the guide rod 65. Proximity switches 13, 14 for controlling the upper and lower limit positions of the slider 64 are provided on the frame 1 .

[0014] The mechanical arm is arranged above the workbench 5 and consists of two sections of front and rear swing arms 21, 22 hinged by pin shafts 25. The other end of the rear swing...

Abstract

The invention relates to a locomotive capacitor shell seam welding machine, which comprises a welding gun, a rack, a working platform, a mechanical arm composed of front and back swing arms hinged with each other, a profile modeling frame horizontally fixed to the rack, and a travelling mechanism moved along a track and a drive device of the travelling mechanism; the other end of the back swing arm is hinged with the rack, so that the front and back swing arms can rotate on horizontal plane; a welding gun fixture is fixed to the front swing arm; the profile modeling frame is provided with the track matched in shape with section of capacitor shell to be welded; and the front swing arm is provided with a connecting arm fixedly connected with the travelling mechanism. The locomotive capacitor shell seam welding machine adopts a mechanical automatic welding process, has uniform welding seam and good weldment quality and can not only improve the quality of the product but reduce the labor intensity, improve the working efficiency and decrease the production cost.

Description

technical field [0001] The invention relates to a device for welding the capacitor casing of a locomotive, in particular to a gap welding machine for the capacitor casing of a locomotive. Background technique [0002] In the production process of oil-immersed water-cooled high-power locomotive capacitors, gap welding of capacitor shells is an essential process. At present, manual welding is usually used for shell gap welding in this process, that is, manually holding a welding torch, and aiming the torch head at the gap of the capacitor shell for welding operation. Due to factors such as technology and experience, it is inevitable that the solder joints to be welded will be uneven, resulting in affected product quality and even defective products. Contents of the invention [0003] The object of the present invention is to address the deficiencies of the prior art, and provide a gap welding machine for the capacitor shell of a locomotive to replace manual welding and impr...
