Summary of the invention
For solving the problems referred to above that prior art exists, the utility model will design a kind of compact conformation and simple a kind of bevel for welding cutter sweep based on slew gear.
To achieve these goals, the technical solution of the utility model is as follows: a kind of groove cut-off apparatus based on slew gear comprises cutting torch frame, slew gear, swing mechanism and Z shaft movement mechanism, described cutting torch frame is installed on the crossbeam of gantry cutting machine, slew gear is installed, in its left hand external the Z shaft movement mechanism is installed by bearing in its through hole; Described Z shaft movement mechanism has leading screw slip through hole and guide post slip through hole, and the outside right side of described slew gear is separately installed with servomotor, decelerator and motor cover, and the slew gear outer left side is equipped with seal cover; In the described swing mechanism central through hole swinging axle is installed, cutting torch is installed in the lower end of swinging axle; Described swing mechanism is installed in the inside of slew gear by bearing, and the connecting axle of described slew gear and cutting torch frame is a hollow shaft, and the service line of cutting torch is concentrated through hollow shaft.
The gyroaxis of slew gear described in the utility model and the swinging axle of swing mechanism all are directly connected to servomotor by decelerator.
Compared with prior art, the utlity model has following beneficial effect:
1, because slew gear gyroaxis of the present utility model is hollow, and swing mechanism is installed in wherein, thereby makes structure compact more and simple and clear, saved the space.
2, because slew gear gyroaxis of the present utility model is hollow, and the service line of cutting torch is all therefrom passed, thereby solve the problem that service line is twined, realized unlimited revolution curve slope cutting.
3, because the gyroaxis of slew gear of the present utility model and the swinging axle of swing mechanism all directly are connected by decelerator,, thereby reduced the sum of errors energy loss of transmission of power intermediate link by motor direct-drive.
4, the utility model structure is simple and clear, saves the space, is easy to processing, and is with low cost.
