The two movable movable plates 203 are respectively threadedly connected to the outer sides of the two screws. The second motor 204 is fixed on the opposite side of the two movable plates 203. The outer sides of the output shafts of the two second motors 204 are both transmission-connected with belts 205. The opposite sides of the two movable plates 203 are rotatably connected to movable columns 206 through bearings, and the opposite sides of the two movable columns 206 are fixed with positioning plates 207.

In this example, the positioning mechanism 2 also includes four electric push rods 208 fixed on opposite sides of the two positioning plates 207, and the automobile parts and shaft parts are respectively fixed between the two electric push rods 208 on the front and rear sides. The two movable columns 206 are respectively connected to the inside of the two belts 205, and a sliding rod is fixed between the opposite sides of the two mounting plates 5. The two movable plates 203 are both slidably connected to the outside of the sliding rod. By starting the first motor 201, since the threaded rod 202 is composed of two screws with opposite thread directions, the two movable movable plates 203 are respectively threadedly connected to the outside of the two screws, and the two movable plates 203 are both slidably connected to the outside of the sliding rod, so that the clamped automobile parts and shaft parts can move relative to each other.

Please refer to Figure 3. In order to absorb and process the harmful smoke, the processing mechanism 4 in this embodiment includes a fan 401 fixed on the upper surface of the base plate, the exhaust end of the fan 401 is fixedly connected to the exhaust pipe 402, a processing box 403 is fixed to the upper surface of the base plate, the left side of the processing box 403 is fixedly connected to the connecting pipe 404, and the right side of the right vertical plate 3 is fixed to the third motor 405.

A connecting plate is fixed to the upper surface of the threaded sleeve 407, and two movable plates 408 are vertically fixed to the upper surface of the connecting plate, and suction heads are fixed on the opposite sides of the two movable plates 408.

In this example, one end of the connecting pipe 404 away from the processing box 403 is fixedly connected to a tee, and one end of the tee away from the connecting pipe 404 is fixedly connected to two hoses, and the two hoses are fixedly connected to two suction heads respectively. Since harmful smoke will be generated during welding, the fan 401 is started to evacuate the processing box 403, so that the two suction heads begin to absorb the harmful smoke and transmit it to the inside of the processing box 403. The two mounting plates 5 are provided with sliding grooves on the opposite sides, and the two movable plates 408 are fixed with sliders connected by sliding grooves on the opposite sides. The harmful smoke is absorbed by the multiple activated carbon plates placed inside the processing box 403. Smoke is filtered to prevent harmful smoke from entering the interior of the fan 401 and damaging the fan 401. A processing door is installed on the front of the processing box 403. A plurality of activated carbon plates are placed vertically inside the processing box 403. The end of the exhaust pipe 402 away from the fan 401 is fixedly connected to the right side of the processing box 403. A positioning rod is fixed between the opposite sides of the two vertical plates 3. The threaded sleeve 407 is slidably connected to the outside of the positioning rod. When the position of the suction head needs to be adjusted to facilitate improving the absorption rate of harmful smoke, the third motor 405 is started to make the screw rod 406 start to drive the threaded sleeve 407 to move horizontally, thereby adjusting the positions of the two suction heads.

It should be noted that the automobile parts and shaft parts are respectively fixed between the two electric push rods 208 on the front and rear sides, and the first motor 201 is started to make the clamped automobile parts and the shaft parts move relative to each other. At this time, the welding machine 6 can be used to weld the gaps between the automobile parts and the shaft parts. The fan 401 is started so that the two suction heads begin to absorb the harmful smoke and transmit it to the inside of the treatment box 403. The harmful smoke is filtered by using multiple activated carbon plates placed inside the treatment box 403. By starting the third motor 405, the screw rod 406 begins to drive the threaded sleeve 407 to move horizontally, thereby adjusting the positions of the two suction heads to facilitate improving the absorption rate of the harmful smoke.

The working principle of the above embodiment is:

(1) When it is necessary to perform production welding on automobile parts, the automobile parts and shaft parts are respectively fixed between the two electric push rods 208 on the front and rear sides, and then the first motor 201 is started. Since the threaded rod 202 is composed of two screws with opposite thread directions, the two movable plates 203 are respectively threadedly connected to the outside of the two screws, and the two movable plates 203 are slidably connected to the outside of the sliding rod, so that the clamped automobile parts and shaft parts move relative to each other. At this time, the welding machine 6 can be used to weld the gap between the automobile parts and the shaft parts.

(2) At the same time, since harmful smoke is generated during welding, the fan 401 is started to evacuate the processing box 403, so that the two suction heads begin to absorb the harmful smoke and transmit it to the inside of the processing box 403. The harmful smoke is filtered by using multiple activated carbon plates placed inside the processing box 403 to prevent the harmful smoke from entering the inside of the fan 401 and damaging the fan 401. At the same time, when it is necessary to adjust the position of the suction head to facilitate improving the absorption rate of the harmful smoke, the third motor 405 is started to make the screw rod 406 start to drive the threaded sleeve 407 to move horizontally, thereby adjusting the position of the two suction heads.
