Abstract
The utility model relates to a rotary platform for welding. The rotary platform comprises a supporting seat, wherein the upper end surface of the supporting seat is movably connected with a platform; a cavity structure is formed between the platform and the supporting seat; a transmission shaft system connected with an output shaft of a speed reducing machine penetrates through a connecting mechanism and the platform in the cavity structure in sequence and is then movably connected with the rotary platform; the other end of the speed reducing machine is connected with the motor; the connecting mechanism consists of a connecting seat and an insulating gasket; the insulating gasket is arranged between the connecting seat and the platform; and the transmission shaft system is movably connected with the platform by a stepped shaft through a deep-groove ball bearing and a single-direction thrust bearing. The rotary platform has the advantages that the parts can rotate at constant speed, the treatment for circumferential welding seams can be finished once, the welding quality is improved and meanwhile the productivity is improved; and the structure is compact and the practicability and the controllability are high.
Description
Technical field
The utility model relates to a kind of frock that is applicable to field of machining, relates in particular to a kind of welding turntable.
Background technology
At present, carrying out weld seam processing for light-wall pipe and thin-walled plate structures ring or light-wall pipe and light-wall pipe structure ring does not have special frock, and the welding process of carrying out structure ring structure in workshop is all that welder's hand rotation part welds.The method is inconvenient operation not only, and weld seam can not once complete, and needs the starting the arc repeatedly to receive arc, and so not only joint is more, affects attractive in appearancely, and joint easily do not merge, produces pore or the weld defect such as lack of penetration, had a strong impact on weldment quality.If adopt manipulator automatic welding, once complete welding by the rotation of welding gun, weldquality is good, but apparatus expensive has high input in early days, is not suitable for small lot batch manufacture.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of welding turntable, being specifically designed to clamping light-wall pipe and thin-walled part or light-wall pipe and light-wall pipe welds, realize by variable-frequency motor and passed motion to welding turntable, drive the workpiece rotation of clamping on welding turntable, complete the welding job of welding gun to workpiece, improve welding quality, reduce workman's the amount of labour, enhance productivity.
For overcoming the above problems, concrete technical scheme of the present utility model is as follows: a kind of welding turntable, comprise supporting seat, supporting seat upper surface is flexibly connected with platform, between platform and supporting seat, form cavity structure, the transmission shaft system being connected with speed reducer output shaft is flexibly connected with turntable after the bindiny mechanism in permeate chamber body structure and platform successively, the other end of reductor is connected with motor, described bindiny mechanism is made up of Connection Block and insulation spacer, insulation spacer is arranged between Connection Block and platform, described transmission shaft system is flexibly connected with platform by deep groove ball bearing and single thrust bearing by multidiameter.
The upper surface of described turntable is uniformly distributed several T-shaped grooves that runs through two ends, turntable left and right, and the indent height of T-shaped groove is less than the height of turntable; The edge, upper surface of turntable is provided with several tapped through holes.
Described motor is variable-frequency motor, and described reductor is S series plagiodont worm-gear speed reducer.
Multidiameter is flexibly connected with platform by deep groove ball bearing and single thrust bearing, wherein deep groove ball bearing can bear larger radial load, and can be used in the motion of High Rotation Speed, sturdy and durable, single thrust bearing can bear larger axial load, play positioning action, prevent the upper and lower play of transmission shaft system, affect welding quality.
Brief description of the drawings
Fig. 1 is the overall schematic of welding turntable.
Fig. 2 is the structural representation of welding turntable except motor and speed reducer.
Fig. 3 is the transmission shaft system structural representation of welding turntable.
Detailed description of the invention
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of welding turntable, comprise supporting seat 1, supporting seat 1 upper surface is flexibly connected with platform 6, between platform 6 and supporting seat 1, form cavity structure, the transmission shaft system being connected with reductor 13 output shafts is flexibly connected with turntable 7 after the bindiny mechanism in permeate chamber body structure and platform 6 successively, the other end of reductor 13 is connected with motor 12, described bindiny mechanism is made up of Connection Block 3 and insulation spacer 4, insulation spacer 4 is arranged between Connection Block 3 and platform 6, described transmission shaft system is flexibly connected with platform 6 by deep groove ball bearing 2 and single thrust bearing 5 by multidiameter.Deep groove ball bearing 2 can bear larger radial load, and can be used in the motion of High Rotation Speed, sturdy and durable; Single thrust bearing 5 can bear larger axial load, plays positioning action, prevents the upper and lower play of transmission shaft system, improves welding quality.
The upper surface of described turntable 7 is uniformly distributed several T-shaped grooves that runs through turntable 7 two ends, left and right, and the indent height of T-shaped groove is less than the height of turntable 7; The edge, upper surface of turntable 7 is provided with several tapped through holes.Several tapped through holes, for by being connected and fixed special tooling with bolt, improve workpiece welding precision.
Described motor 12 is variable-frequency motor, and described reductor 13 is S series plagiodont worm-gear speed reducer.
The course of work:
The special tooling of clamping parts is tightened by several screwed holes at bolt and turntable 7 edges, upper surface, adjust turning to of turntable 7, welding gun ground wire is connected with frock, treats arc stability after the starting the arc, starter motor 12, motor 12 will move through reductor 13 and pass to turntable 7, and turntable 7 drives the special tooling rotation of clamping parts, and welding gun starts girth joint welding, after having welded, welding gun is received arc, disable motor, and welding completes.
