Description
Technical field
The present invention relates to a kind of device that two sections pipes are positioned of being used for.Specifically exactly two sections identical pipes of diameter are located centering fast, two sections pipes can be welded easily, applicable to the pipe of different tube diameters series.
Background technology
Various pipelines on the ship are called " blood vessel " of boats and ships, as the predominating path of ship power transmission, delivering vapor, gas, water and wet goods; In boats and ships, play considerable effect; When in the shipbuilding process, need carrying out centering welding, when the pipe of two sections same diameter is welded together, need carry out space orientation to two sections pipes earlier to a large amount of pipelines; Make two sections circle pipe centerings, just can weld then.
At present, mostly be artificial fixed form to carrying out sterically defined mode before two sections pipe welding.Though the centering of adopting artificial fixed form also can realize two sections pipes needs through repeatedly measuring, the range estimation positioning accuracy is low, needs to adjust repeatedly to realize welding, wastes time and energy.
Adopt caliber self adaptation pipe apparatus for welding and positioning can avoid above problem.Chinese patent CN200991869Y discloses a kind of pipe automatic centering device, and the inwall that this patent adopts hydraulic pressure to promote location tooth bar and pipe as power source offsets and positions, and this patent need be used hydraulic system, and cost is higher, and plant maintenance bothers.
Summary of the invention
Of the present invention a kind of caliber self adaptation pipe apparatus for welding and positioning is provided.Use this caliber self adaptation pipe apparatus for welding and positioning that two sections pipes are carried out centering, positioning accuracy is high, does not need external power supply, and plant maintenance is simple, and is time saving and energy saving, wherein locatees the pipe that the free folding of tooth bar can adapt to different tube diameters series.
The technical solution adopted for the present invention to solve the technical problems is:
Caliber self adaptation pipe apparatus for welding and positioning comprises same cardiac skeleton, location tooth bar, rotating shaft, servo-actuated cylinder sleeve, drive screw, left locking nut, right locking nut, left axle sleeve, right axle sleeve, left end cap and right end cap.Described have three planes and three axial pass troughs that are centrosymmetric with cardiac skeleton on circumferentially, and each axial pass trough is arranged in the middle of the corresponding plane, on axial pass trough, is processed with key seat; Key seat is equipped with the location tooth bar through rotating shaft, upwards is processed with three planar axes the week of servo-actuated cylinder sleeve to tooth bar, and three planar axes circumferentially are uniformly distributed with along the lateral surface of servo-actuated cylinder sleeve respectively to tooth bar; And respectively with corresponding with the axial pass trough on three planes of cardiac skeleton, described location tooth bar one side is an arcwall face, and opposite side is processed into dome; Wherein be processed with tooth on the arcwall face; And put corresponding axially tooth bar with servo cylinder and be meshed, the dome of location tooth bar opposite side then offsets with the inwall of pipe one and pipe two, and servo-actuated inboard wall of cylinder liner hollow also is processed with motion thread; Motion thread is meshed with drive screw; The drive screw two ends are equipped with left axle sleeve and right axle sleeve, are fixed on on the cardiac skeleton through left end cap and right end cap, and utilize left locking nut and right locking nut to lock.
The invention has the beneficial effects as follows: the present invention has adopted the servo-actuated cylinder sleeve that can realize left and right sides bidirectional-movement, utilizes the rotation of drive screw to drive the side-to-side movement of servo cylinder cover, rotates around the axis thereby drive the location tooth bar; Make the dome of location tooth bar and the inwall of pipe one and pipe two offset, two sections pipes are concentric about forcing, and realize the automatic concentric locating of pipe fast; Use the screw thread force-increasing mechanism, the dome that available less power realizes the location tooth bar is the inwall of pipe one and pipe two fixedly, and the self-locking of realization servo-actuated cylinder sleeve; Pipe one can centering be located with pipe two all the time when guaranteeing welding, has saved hydraulic system, and plant maintenance is simple; Reduce cost, compare, do not need repeatedly to measure, just adjust and to realize high-precision location with artificial pipe location centering; Exempted the fixing step of spot welding, time saving and energy saving.
