Description

Welding gun of push-pull wire robot Technical Field The utility model relates to a welding gun of a push-pull wire robot, and belongs to the technical field of welding guns of push-pull wire robots. Background The wire feeding mechanism of the wire pushing and drawing robot welding gun is arranged on the welding gun, welding is carried out by using welding wires, and the diameter of the welding wires is generally 1.0-1.6mm. The wire feeding mechanism comprises a pair of wire feeding wheels and a wire pressing wheel, and the wire feeding wheels are driven by a motor. The welding gun of the wire pushing and drawing robot in the prior art has the problem that a wire feeding wheel driving motor heats seriously, so that the production stability is influenced, the installation position of the wire feeding wheel is generally inconvenient to observe, the wire feeding wheel cannot be found out in time when abrasion occurs, and the production efficiency is influenced. Disclosure of utility model The utility model provides a welding gun of a push-pull wire robot, which aims to overcome the defects in the prior art, improve the heating condition of a wire feeding wheel driving motor and improve the convenience of observation and replacement of the wire feeding wheel. The technical scheme includes that the welding gun of the push-pull wire robot structurally comprises a gun head bent pipe, a wire feeding mechanism and a bumper, wherein the gun head bent pipe, the wire feeding mechanism and the bumper are sequentially connected, the wire feeding mechanism comprises a wire feeding wheel and a wire pressing wheel which are installed on a main body and are adjacently arranged, welding wires pass through the space between the wire feeding wheel and the wire pressing wheel, the wire feeding wheel is installed at the driving end of a driving motor, the driving motor is located at the bottom of the main body, water through blocks are arranged on two sides of the driving motor, the top of each water through block is connected with the bottom of the main body, a cooling waterway is arranged in each water through block, and a heat-conducting silica gel sheet is arranged between the driving motor and each water through block. And when the welding gun works, the heat of the operation of the driving motor can be transferred to the water through block through the heat conducting silica gel sheet. Because the water flows in the water through block, most heat of the driving motor can be taken away, and the normal operation of the driving motor is ensured. Preferably, the main body is a main copper piece, and the water-through block is a red copper water-through block. The heat conduction silicon sheet can realize heat conduction and insulation between the water through block and the driving motor.
