Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without making creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution: a smoke and dust removing device of a numerical control plasma cutting machine is arranged on a movable power head 7 of the plasma cutting machine, and a gun head 6 is arranged at the bottom of the power head 7. The power head 7 is a component which can move in a coordinate system range in the numerical control plasma cutting machine, is used for communicating and fixing the gun head 6, and can drive the gun head 7 to move to a specified cutting position of the numerical control plasma cutting machine.
The smoke and dust removing device of the numerical control plasma cutting machine comprises a rotating ring 5 which is rotatably connected with the periphery of a ring power head 7, the rotating ring 5 is connected with a rotary driving unit which drives the rotating ring to rotate relative to the power head 7, a cross arm 10 which extends outwards along the radial direction of the rotating ring 5 is arranged on one side of the rotating ring 5, a dust removing bin 11 is pivoted at the extending end of the cross arm 10, the dust removing bin 11 is in a hollow cylindrical shape, one end of the dust removing bin is open, the open end of the dust removing bin 11 faces downwards, and the top end of the dust removing bin 11 is pivoted with the extending end of the cross arm 10. The side wall of the dust removing bin 11 is provided with a pipe connector 12 communicated with the interior of the dust removing bin. The external air extraction equipment or negative pressure equipment works to connect the pipe connector 12 through the pipeline, so that negative pressure is generated inside the dust removing bin 11, and thus, smoke dust generated when the air flow at the open end of the dust removing bin 11 drives the gun head 6 to cut is sucked into the dust removing bin 11 and then is discharged and collected through the pipe connector 12, or further deep treatment is performed.
In the present embodiment, the dust removing compartment 11 is connected to a turning drive unit for turning the dust removing compartment around the pivot position with the horizontal arm 10. The overturning driving unit comprises an overturning seat 9 pivoted on the other position of the cross arm 10, an electric push rod 15 is fixedly installed at one end of the overturning seat 9, a movable block 14 is connected to the tail end of a telescopic rod of the electric push rod 15 through threads, and the movable block 14 is pivoted with the side wall of the dust removal bin 11. The distance between the movable block 14 and the turning seat 9 is further changed by the extension and retraction of the telescopic rod of the electric push rod 15, so as to drive the dust removing bin 11 to turn around the pin joint position with the cross arm 10. In the process of collecting the cutting smoke dust, the dust removal bin 11 is driven to perform overturning motion through the overturning driving unit, the mouth orientation of the dust removal bin 11 can be adjusted, the smoke dust collection angle of the dust removal bin 11 is further adjusted, the collection area is enlarged, and the dust removal efficiency is improved.
In this embodiment, the open end of the dust removing bin 11 is provided with a collecting port 13 which is flared and the flaring direction of which is downward. When the collection port 13 is in the lowermost position, the direction of the collection port is exactly aligned with the cutting position of the lance tip 6 for the metal. Through the flaring-shaped collecting port 13, the collecting range of the smoke is expanded, and the smoke collecting efficiency is improved.
The rotary driving unit in the embodiment comprises a mounting ring 8 fixedly sleeved on the periphery of a ring power head 7, a support arm 2 extending outwards along the radial direction of the mounting ring 8 is arranged on one side of the mounting ring 8, a motor 1 is installed on the support arm 2, and a driving gear 3 is fixedly installed on an output shaft of the motor 1. An annular rack 4 with an open ring structure is fixedly sleeved on the periphery of the rotating ring 5, and the annular rack 4 is meshed with the driving gear 3. Since the open position of the ring-shaped rack 4 is the position where the horizontal arm 10 extends, the rotary ring 5 and the pinion gear 3 rotate reciprocally relative to each other. The external power supply supplies power to the motor 1, and the motor 1 rotates and drives the driving gear 3 to rotate, so that the driving gear 3 drives the annular rack 4 to rotate, and further the rotating ring 5 can be driven to rotate synchronously, the dust removal bin 11 is driven to rotate around the power head 7, and the collection range of the dust removal bin 11 to smoke dust is further enlarged.
