Embodiment
Below in conjunction with accompanying drawing, brief description is made to embodiment of the present utility model.
As shown in Figure 1, a kind of gas pipeline laser-impact test multistation clamping device, motion structure mainly contains three parts: gas pipeline clamping and revolution drive part; Pipeline support adjustable length, variable diameters pipeline can support sections; Pipeline axial Feed servo system part.
As shown in Figure 2 and Figure 3, fixed support positioning and clamping mechanism.
Mechanism's chief component: end cap 2, cylindrical roller 3, outer coil support 4, fishbolt 5, inner ring 6 and screw 1.Wherein, cylindrical roller 3 is selected can to ensure the stability of gas pipeline rotary motion; The base of outer coil support 4 is fixed on movable base plate 28, realizes the feed motion along pipeline axial; Three fishbolts 5 are distributed in 120 ° of inner ring 6 and divide equally on direction, realize three-point fix and clamping, and the clamping realizing pipe diameter 90mm to 270mm are adjustable; Inner ring 6 is designed with a circle tooth 36, it engages with driven wheel and realizes rotary motion.
Gas pipeline outside surface to be held is unprocessed, and clamping adopts three-point fix, can avoid location and owe location, ensures that pipeline rotates stable.The thickness of outer coil support 4 is little, under the condition not affecting strength structure, is easily stretched out from this structure by pipeline.Outer coil support is bolted on movable base plate, in order to ensure the stability of support, and support envisaged underneath understructure.Inner ring structure designs processing one and enclose tooth, drive gear wheel 29 to be meshed with the tooth on inner ring 6 by revolution, realize gas pipeline along axis rotation.
As shown in Figure 4, Figure 5, traversing carriage mechanism.
The chief component of mechanism: handle 7, leading screw 8, bearing 9, bearing sleeve 10, roller bolt 11, roller 12, support arm 13, movable block 14, bracket slide seat 15 and clamping screw 16.Wherein, the pin-and-hole of movable block 14 is vertical with the center line antarafacial of threaded hole, and movable block 14 is connected by pin with support arm 13.On two support arms 13, the threaded hole one of movable block is left-handed, a dextrorotation.During work, first clamping screw 16 is unscrewed, rotational lead screw 8 again, two movable blocks moving axially along leading screw 8, drive the swing of support arm 13, drive bearing sleeve 10 to slide on vertical rail 37 simultaneously, tighten clamping screw 16 after arriving adjusting angle, thus realize the support to the pipeline of different-diameter (90mm ~ 270mm).
Support arm 13 tip designs has trundle 12, is beneficial to the rolling of gas pipeline on support.Frame bottom is sliding seat, and sliding seat coordinates with movable base plate head rail, realizes the support to the pipeline of different length by the relative position of both changes.
As shown in Figure 6, fixed base plate structure.
Fixed base plate structure 26 is arranged in cement platform, is designed with two base plate rails 31, to be angle bottom base plate rail 31 the be inclined-plane of 120 degree.For ensureing that pipeline has the space of feeding in the longitudinal direction of base plate, so the length of base plate should be greater than the maximum length 4000mm of gas pipeline.Motor and speed reduction unit to be placed in fixed base plate structure 26, and interference can not be formed to gas pipeline during running, suitably widen base plate.
Will realize the rotary motion of gas pipeline along axis in the utility model, itself and axial feed motion are separate two and move.Therefore, two drive motor are placed on different base plate platforms, and then realize non-interference.
Movable base plate structure as shown in Figure 7.
Movable base plate structure 28 forms primarily of drive installation seat 33, fixed support mount pad 34, rail plate 32 and tooth bar 17, and tooth bar 17 is connected with bolt with movable base plate structure.Drive installation seat 33 installs back rotating motor 30 and rotary reducer 25; Mounting and fixing bracket positioning clamping structure on fixed support mount pad 34; Traversing carriage structure is moved on rail plate 32; Driving pinion 18 engages with tooth bar 17, drives whole movable base plate structure 28 along gas pipeline 27 axially-movable.
When gas pipeline 27 moves in the axial direction, drive pinion wheel 18 to make the parts installed in fixed base plate structure 26 also can carry out feed motion by feeding motor 23 simultaneously.So the bottom of movable base plate structure 28 needs certain height, driven wheel can be made to be put between fixed base plate structure and movable base plate structure.
The length of movable base plate structure suitably should be less than the length of fixed base plate structure, meanwhile, and can not much smaller than the maximum length of gas pipeline.Meanwhile, also connecting tube locating and clamping apparatus to be carried out by bolt on the components, for preventing the threaded hole of coupling bolt from not interfering with each other with rack structure below and guide rail structure, also corresponding dimensional requirement will be considered when arranging threaded hole.
As shown in Figure 8, feeding driving mechanism.
Feeding driving mechanism forms primarily of tooth bar 17, pinion wheel 18, transmission shaft 19, feeding bearing 20, feeding speed reduction unit 21, shaft coupling 22, feeding motor 23 and output shaft 24.During work, pinion wheel 18 rotates, the gas pipeline 27 driving movable base plate 28 and install, and the overall guide rail movement along fixed floor 26, completes the feed motion along gas pipeline axis.
As shown in Figure 9, rotary motion mechanism.
During work, turning motor 30 outputs power on gear wheel 29 by rotary reducer 25, and gear wheel 29 engages with the circle tooth 36 on the inner ring 6 of clamping device, drives the gas pipeline 27 of inner ring 6 and installation to rotate, completes the gyration of gas pipeline along axis.
Working method:
Positioning clamping: according to gas pipeline length and external diameter, first adjusts fishbolt 5, be able to pass through inner ring 6 with gas pipeline 27; Turning leading screw 8 makes support arm 13 swing, and the bearing height of adjustment gas pipeline 27, makes it pass inner ring 6; And according to duct length, the position of adjustment two traversing carriages; Finally tighten three fishbolts 5 simultaneously.Like this, by regulating the grip bolt 5 on fixed support positioning and clamping mechanism, coordinating bearing height and the distance of adjustment traversing carriage, the positioning clamping of the gas pipeline 27 to different-diameter, different length can be realized.
Impulse test: start turning motor 30, gas pipeline 27 rotates vertically, gas pipeline 27 is arranged on the guide rail feeding of the mechanism in movable base plate structure 28 along fixed base plate structure 26 with whole, laser impacts from traversing carriage side to gas pipeline 27, along with the motion of pipeline, laser can impact the whole outside surface of gas pipeline.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
