[0019] Furthermore, a positioning method for a marine machinery seat welding positioning device comprises the following steps:

[0020] Step 1: After the plywood clamps and fixes the seat, turn on motor 2 to drive the worm to rotate in the fixed box. The rotation of the worm can drive the shaft to rotate in the fixed box through the worm gear. The rotation of the shaft can drive the plywood to rotate. The rotation of the plywood can drive the seat to rotate. By setting a rotating component, the seat after clamping and fixing can be rotated and adjusted, which is convenient for welding work on different positions of the seat. By setting a supporting component, when the plywood rotates, the slides at one end of several connecting columns at one end of the plywood can slide in the annular rail at one end of the fixed box. At the same time, several reinforcing columns are set between the connecting column and the plywood, and between the connecting column and the slide to make the connection between the connecting column and the plywood, and between the connecting column and the slide stronger. By setting the supporting component, the connection between the plywood and the fixed box is more stable, and the rotation of the plywood is more stable.

[0021] Step 2: Turn on the suction fan during welding work. The suction fan generates negative pressure in the dust hood through the dust reduction box and the connecting pipe. The smoke generated by welding is sucked into the dust hood, and then the smoke enters the dust reduction box. The smoke is filtered through the sand and gravel layer and the activated carbon layer in the dust reduction box. By setting the dust reduction component, the smoke generated by welding can be treated to reduce the pollution of the smoke to the air. By setting the installation component, the sand and gravel layer and the activated carbon layer are inserted into the card slot in the dust reduction box through the installation port when installing the sand and gravel layer and the activated carbon layer, and then the installation plate is placed in the installation port, and finally the installation bolts are screwed into the installation hole to fix the installation plate, so as to achieve the effect of limiting and fixing the sand and gravel layer and the activated carbon layer. The installation component is provided to facilitate the disassembly and replacement of the sand and gravel layer and the activated carbon layer;

[0022] The third step is to pull the pull plate to drive the slide bar and the limit plate to slide in the fixed frame, and the spring is compressed. Then the chip box is placed on the base until the rear end of the chip box is close to the positioning plate. Then the pull plate is released, and the spring extends to push one end of the slide bar into the card hole on the side of the chip box to achieve the effect of limiting and fixing the chip box. The chip box can receive the waste chips dropped by welding. By setting the chip collection assembly, the waste chips generated by welding can be collected in a centralized manner to avoid the waste chips falling at will and polluting the processing environment. By setting the limit assembly, when there is no need to pull the pull plate, the rotating rod is toggled by the toggle rod, and the rotating rod is rotated on one side of the fixed frame through the pin shaft. After the rotating rod is rotated to the plate at one end of the pull plate, the rotating rod can limit the pull plate to avoid the pull plate being pulled by mistake.

[0023] Step 4: When the device needs to be moved, turn on motor 3 to drive the stud to rotate. The rotation of the stud drives the moving seat to move in the bottom box. The movement of the moving seat drives the T-shaped seat to slide in the slide groove at the upper end of the turn plate through the vertical rod. The movement of the T-shaped seat pushes the turn plate to rotate in the bottom box. The rotation of the turn plate rotates the universal wheel at the lower end out of the bottom box, thereby lifting the device. The device can be moved by the universal wheel. By setting up a moving component, the device can be easily moved and the device can be easily moved to different positions for use.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The present invention sets a rotating assembly. After the splint clamps and fixes the seat, the second motor is turned on to drive the worm to rotate in the fixed box. The rotation of the worm can drive the rotating shaft to rotate in the fixed box through the worm gear. The rotation of the rotating shaft can drive the splint to rotate. The rotation of the splint can drive the seat to rotate. By setting the rotating assembly, the seat can be rotated and adjusted after being clamped, which is convenient for welding work at different positions of the seat.

[0026] 2. The present invention sets a dust reduction component. When welding is carried out, the suction fan is turned on. The suction fan generates negative pressure in the dust hood through the dust reduction box and the connecting pipe. The smoke generated by welding is sucked into the dust hood, and then the smoke enters the dust reduction box. The smoke is filtered through the sand and gravel layer and the activated carbon layer in the dust reduction box. By setting the dust reduction component, the smoke generated by welding can be treated by dust reduction, thereby reducing the pollution of the smoke to the air.

[0027] 3. The present invention sets a chip collection component, pulls the pull plate to drive the slide rod and the limit plate to slide in the fixed frame, and the spring is compressed. Then the chip collection box is placed on the base until the rear end of the chip collection box is close to the positioning plate, and then the pull plate is released. The spring stretches and pushes one end of the slide rod into the card hole on the side of the chip collection box, thereby achieving the effect of limiting and fixing the chip collection box. The chip collection box can receive the waste chips dropped by welding. By setting up the chip collection component, the waste chips generated by welding can be collected in a centralized manner to prevent the waste chips from falling randomly and polluting the processing environment.

[0028] 4. The present invention sets a moving component. When the device needs to move, the motor 3 is turned on to drive the stud to rotate. The rotation of the stud drives the moving seat to move in the bottom box. The movement of the moving seat drives the T-shaped seat to slide in the slide groove at the upper end of the rotating plate through the vertical rod. The movement of the T-shaped seat pushes the rotating plate to rotate in the bottom box. The rotation of the rotating plate rotates the universal wheel at the lower end out of the bottom box, thereby lifting the device. The device can be moved by the universal wheel. The setting of the moving component facilitates the movement of the device, and the device can be easily moved to different positions for use. BRIEF DESCRIPTION OF THE DRAWINGS
