Abstract
The utility model discloses a vertical type connecting-rod-type intersecting line cutting head which comprises a main arm, a driven gear shaft and a swing angle component arranged on the driven gear shaft, the driven gear shaft is arranged on the main arm through a bearing, a reverse-rotation speed-reducing motor is arranged on the main arm, and the driven gear shaft is driven to rotate reversely due to the fact that a driving gear arranged on the rotary speed-reducing motor is meshed with a driven gear on the driven gear shaft. A rack is fixedly arranged on the lower portion of the driven gear shaft through a round nut, the swing angle component is arranged on the rack, and accurate angle-swinging at +- 90 degrees of a cutting torch is achieved through a four-connecting-rod mechanism of the swing angle component. The vertical type connecting-rod-type intersecting line cutting head can simply achieve organization motions needed by cutting of pipes through the combination of the rotary mechanism and the swing angle component, and ensures that the height position of a cutting point during a lifting process of a pipe fitting is constant. Due to the fact that only a rotary shaft is in linkage with a swing angle shaft, electric control is relatively simple, and programming workload is reduced in a large range.

The technical scheme that the utility model further limits is: aforesaid vertical link type intersection cutting head, described driven gear shaft is hollow structure, in described driven gear shaft, be installed with tracheae and electric wire, when head turns round, electric wire, tracheae etc. can not twined, reduce rate of breakdown.
Aforesaid vertical link type intersection cutting head, described four connecting rod reducing motors are L type structure, have so just shortened the length of reducing motor greatly, avoid motor and tracheae, electric wire to rub.
The vertical link type intersection cutting head of stating, described four connecting rod reducing motors are connected to form by servomotor and planetary reducer.
Further, aforesaid vertical link type intersection cutting head, described cutting torch is flame type cutting torch or plasma type cutting torch.
The beneficial effects of the utility model are: the utility model only can be realized the required mechanism action of pipe cutting by the combination of slew gear and pivot angle assembly, this covering device has guaranteed that pipe fitting height and position of cut point in lifting process is constant, because have only revolution, pivot angle two-axle interlocking, electrical control is simple relatively, and the programing work amount significantly reduces.Original horizontal quadric chain frame and connecting rod are horizontally disposed, have hindered cutting torch and have realized big pivot angle cutting.The utility model patent has adopted the mode with the vertical layout of four-bar mechanism, can realize cutting torch ± 90 degree cuttings.Because the vertical layout of mechanism, eliminated rod member because the winding degree deviation that deadweight produces, transmission precisely and member structure can do small and exquisitely relatively.The rotary decelerating motor is installed on the principal arm top, and is simple for structure, easy for installation, and saved the head space.
