Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of rotary tank case end socket inner loop welder that guarantees welding quality is provided.
The utility model is to be achieved by the following technical programs:
A kind of rotary tank case end socket inner loop welder, comprise centralized positioning axle, center be fixed on centralized positioning axle and front and back arrange two three-pawl type locating racks and be located at the gas shielded welding frame that centralized positioning axle top is connected by bearing with centralized positioning axle, 60 ° of the axial phase phasic differences of described two three-pawl type locating racks, described three-pawl type locating rack comprises the locating detent at 120 °, three isometric intervals and is located at the centralized positioning card at locating detent center, described centralized positioning card and centralized positioning axle are affixed, described gas shielded welding frame comprises hack lever, be located at the balancing weight of hack lever one end and be located at the soldering tip with gas shield cover of the hack lever other end.
Described locating detent is provided with axial-adjustment unit.
Described axial-adjustment unit is adjusting screw(rod).
The top of described gas shield cover is the circular arc matching with tank case end socket inside.
The beneficial effects of the utility model are:
Due to two three-pawl type locating racks being set, 60 ° of two axial phase phasic differences of three-pawl type locating rack, described three-pawl type locating rack comprises the locating detent at 120 °, three isometric intervals and is located at the centralized positioning card at locating detent center, described centralized positioning card and centralized positioning axle are affixed, so overall locating rack contacts the location point different for 6 of 60 ° of phase phasic differences from tank case, guarantee the concentricity of centralized positioning axle and tank case, thereby guaranteed welding quality.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model.
Fig. 2 is two three-pawl type locating rack arrangement schematic diagrames of the present utility model.
In figure: 1. the first three-pawl type locating rack, 2. the second three-pawl type locating rack, 3. adjusting screw(rod); 4. centralized positioning axle, 5. bearing, 6. hack lever; 7. gas shield cover; 8. air inlet pipe, 9. end socket, 10. cylindrical shell; 11. weld seams; 1-1,1-2,1-3. the first three-pawl type locating rack locating detent, 2-1,2-2,2-3. the second three-pawl type locating rack locating detent.
The specific embodiment
In order to make those skilled in the art understand better the technical solution of the utility model, below in conjunction with accompanying drawing and most preferred embodiment, the utility model is described in further detail.
As shown in the figure, the utility model comprises centralized positioning axle 4, two three-pawl type locating racks (the first three-pawl type locating rack 1 that center is fixed on centralized positioning axle and front and back arrange, the second three-pawl type locating rack 2) and be located at the gas shielded welding frame that centralized positioning axle top is connected by bearing 5 with centralized positioning axle, 60 ° of the axial phase phasic differences of described two three-pawl type locating racks, described three-pawl type locating rack comprises the locating detent at 120 °, three isometric intervals and is located at the centralized positioning card at locating detent center, described centralized positioning card and centralized positioning axle are affixed, described gas shielded welding frame comprises hack lever 6, be located at the balancing weight of hack lever one end and be located at the soldering tip with gas shield cover 7 of the hack lever other end.Described in this example, locating detent is provided with axial-adjustment unit.Convenient fine setting centering.Described axial-adjustment unit is adjusting screw(rod) 3.The top of described gas shield cover is the circular arc matching with tank case end socket inside.Prevent that gas shield cover and tank case end socket inside from rubbing mutually.
