Description
Technical field
This technology relates in steam turbine assembling process, and the steam turbine used when cylinder at different levels connects cylinder assembling connects cylinder smoothing measurement mechanism.
Background technology
It is one important procedure in Steam Turbine Manufacturing Process that steam turbine cylinder at different levels connects cylinder assembling, and when carrying out this procedure, after needing the horizontal flange adjusting cylinder at different levels to ensure to connect cylinder, the horizontal flange flatness of cylinder at different levels meets design requirement.In order to measure this flatness, usual needs winch to boring and milling machine by connecing the lower cylinder halfs at different levels after cylinder, lathe drags dial gauge measure, this workload is very large, have influence on production efficiency, and under the prerequisite not having measurement mechanism, be all after welding is good, on gantry mill, brush finish ensures flatness, directly affects the machining precision of product.
Summary of the invention
The object of this technology is to provide a kind of steam turbine and connects cylinder smoothing measurement mechanism, its simple structure, easy to use, can the difference of height of accurately MEASUREMENT OF STEAM turbine cylinder at different levels and bearing seat horizontal flange, flatness error can be found in advance with this device before connecing cylinder welding, reach best by equipment adjustment and machine work reparation and connect cylinder state, improve the assembly precision of steam turbine.
Steam turbine described in this technology connects cylinder smoothing measurement mechanism, comprise base, there is line slideway, the travelling carriage of guide and movement parts, the bottom surface of base is parallel with movement parts moving direction, and guide is fixed on base, and travelling carriage is connected with one end of movement parts; Dial gauge is arranged on one end of travelling carriage, and moving direction and the movement parts moving direction of the sounding rod of dial gauge are perpendicular.
The beneficial effect of this technology: during use, the bottom surface of base is fixed on the horizontal flange of a cylinder, and by dial gauge zero setting on this cylinder horizontal flange, then travelling carriage is dragged, dial gauge is made to move on the horizontal flange of another cylinder, change in size is measured with dial gauge, now dial gauge react the difference of height that reading is two cylinder horizontal flanges, the flatness error of two cylinder horizontal flanges can be determined by repetitive measurement, reach best by equipment adjustment and machine work reparation and connect cylinder state, improve the assembly precision of steam turbine.
Above-mentioned steam turbine connects cylinder smoothing measurement mechanism, and travelling carriage is connected with the meter reading back up pad that can move up and down on the moving direction of sounding rod, and dial gauge is connected in meter reading back up pad.When needs measurement two planes have certain altitude difference time, meter reading back up pad can be moved, make dial gauge with meter reading back up pad lifting certain altitude.
Above-mentioned steam turbine connects cylinder smoothing measurement mechanism, and base is provided with magnet.Can be fixed the absorption of this device by magnet.
Above-mentioned steam turbine connects cylinder smoothing measurement mechanism, and travelling carriage is provided with dog screw, and when making dog screw and base contacts when rotational positioning screw, travelling carriage can not move relative to base.

Embodiment
Below in conjunction with embodiment and application examples, this technology is elaborated.It is pointed out that illustrated embodiment is the better embodiment of this technology, instead of the restriction to this technical requirement protection domain, the application of this technology and using method are also not limited to lifted application examples.
Cylinder smoothing measurement mechanism is connect see the steam turbine shown in Fig. 1,2, comprise: meter reading back up pad 1, front end-plate 2, travelling carriage 3, the guide of 4 line slideways, high-head knurling screw (dog screw) 5, the movement parts 6 of line slideway, attachment screw 7, attachment screw 8, attachment screw 9, base 10, attachment screw 11.
Meter reading back up pad 1 is arranged on front end-plate 2 by attachment screw 11, front end-plate 2 is arranged on travelling carriage 3 by attachment screw 8, travelling carriage 3 is arranged in the movement parts 6 of line slideway by attachment screw 9, the movement parts 6 of line slideway can relative to guide 4 linear slide, guide 4 is arranged on base 10 by attachment screw 7, base plate is equipped with magnet, can be adsorbed on workpiece level split.Dial gauge peace 12 is contained in meter reading back up pad 1.
Travelling carriage is provided with high-head knurling screw 5, and when high-head knurling screw being contacted when rotating high-head knurling screw 5 with guide, travelling carriage can not move relative to base.
As shown in Figure 5, middle cylinder and front cylinder two cylinder connect cylinder assemble time, this device to be placed in two cylinders vertical joint face 15 side on cylinder horizontal flange 13, the absorption of this device fixes by base bottom magnet, by dial gauge zero setting on middle cylinder horizontal flange, drag travelling carriage, dial gauge is moved on front cylinder horizontal flange 14, change in size is measured with dial gauge, now dial gauge react the difference of height that reading is two cylinder horizontal flanges, the flatness error of two cylinder horizontal flanges can be determined by repetitive measurement, reach best by equipment adjustment and machine work reparation and connect cylinder state, improve the assembly precision of steam turbine.
This device can also measure the flatness of horizontal flange between cylinder and bearing seat in addition, as shown in Figure 5, when cylinder and bearing seat assemble, the horizontal flange of two workpiece is not direct contact, after this device is arranged on cylinder horizontal flange 16, drag travelling carriage, dial gauge can measure on the horizontal flange 17 of bearing seat by the guide rail stroke of this device, in like manner can measure the flatness error of cylinder and bearing seat.
In addition, this device also has with a face for benchmark, measure the function of another face relative to this face depth of parallelism, as shown in Figure 7, this device is fixed on a reference field 18, meter reading back up pad is adjusted to correct position on front end-plate vertical direction, measures the difference of height of 3 points in another plane 19, just can calculate the depth of parallelism of this plane 19 and reference field 18.
This device be applicable to cylinder at different levels in Steam Turbine connect cylinder assembling time, accurately can measure the difference of height of cylinder at different levels and bearing seat horizontal flange, flatness error can be found in advance with this device before connecing cylinder welding, reach best by equipment adjustment and machine work reparation and connect cylinder state, improve the assembly precision of steam turbine, this device has good ease for use and portability, can improve efficiency of assembling.
