Abstract
The utility model relates to a horizontal stator center measuring stand, which comprises a central column, a rotating arm, a measuring gauge stand, a positioning sleeve and a rotating shaft sleeve; the positioning sleeve is sleeved on the stator central column; the rotating shaft sleeve is mounted on the positioning sleeve through a thrust bearing; the detachable rotating arm is connected on the rotating shaft sleeve through a bolt; and the measuring gauge stand is fixedly connected at the outer end of the rotating arm through bolts. The utility model has the advantages that the measuring stand is accurately positioned with small error, has strong operability and ensures the implementation of each dimension of stator center in the time-saving and labor-saving manner; and the measuring stand lays the favorable foundation for the next stator rib-swinging and chipping procedures and is an indispensable tooling for stator assembly of the large-scale mixed flow and axial flow machine set.
Description
Technical field
The utility model belongs to field of motor manufacturing, particularly relates to a kind of stator center horizontal survey frame.
Background technology
At present, the out frame of mixed flow unit and axial flow unit all adopts large-scale ring flat-plate welding to constitute in the hydrogenerator, can cut down finished cost significantly like this.In support, install the location gusset between ring flat-plate and the support lower ring plate, therefore, need on the support internal diameter, corresponding base be set on schedule, i.e. the levelness of centering lower ring plate.Owing to the out frame after the welding not in the reasons such as collision of processing in internal diameter, ring flat-plate welding deformation and the transportation, cause support to deform easily, decide horizontal operation therefore for the stator seat and brought certain difficulty, can't guarantee to design the relative dimensions precision of proposition, cause next procedure to carry out, thereby can not guarantee the quality of out frame pendulum weldering positioning bar.
Summary of the invention
The utility model provides a kind of stator center horizontal survey frame simple in structure, easy to use for solving the technical matters that exists in the known technology.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:
Stator center horizontal survey frame, it is characterized in that: comprise newel, pivoted arm, measurement gauge stand, locating sleeve and rotary axle box, be set with locating sleeve on the newel, by thrust bearing rotary axle box is installed on the locating sleeve, be connected with removable pivoted arm by bolt on the rotary axle box, the pivoted arm outer end is fixed with the measurement gauge stand by bolt.
The utility model can also be by the following technical solutions:
Described locating sleeve and newel are clearance fit, uniformly on the locating sleeve are shaped on three threaded holes, and locating sleeve is by jackscrew and newel location.
Described rotary axle box and newel are for movingly.
Described rotary axle box is to be made of steel pipe and the brass bushing that is inlaid in the steel pipe.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, when need on the support internal diameter, be provided with, during the levelness of centering lower ring plate and positioning bar, this stator measurement bay is placed in the support, and on the measurement gauge stand of pivoted arm outer end, dial gauge is installed, can finish levelling.In addition, pivoted arm adopts dismantled and assembled structure, so that adapt to the ring flat-plate of different radii and satisfy the measurement needs of support internal diameter in various degree.The accurate positioning of this measurement bay, error are little, workable, guarantee the enforcement of each size, and be time saving and energy saving, lays a good foundation for next procedure stator pendulum muscle and chip, is that the stator of large-scale mixed flow and axial flow unit assembles indispensable frock.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, newel; 2, pivoted arm; 3, measure gauge stand; 4, locating sleeve; 5, rotary axle box; 6, thrust bearing; 7, jackscrew.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
A kind of stator center horizontal survey frame comprises newel 1, pivoted arm 2, measures gauge stand 3, locating sleeve 3 and rotary axle box 4, and described rotary axle box 4 is to be made of steel pipe and the brass bushing that is inlaid in the steel pipe.Be set with on the newel 1 and can prolong its locating sleeve that axially moves up and down 5, described locating sleeve and newel are clearance fit.By thrust bearing 6 rotary axle box 4 is installed on the locating sleeve 5, rotary axle box and newel are for movingly.Rotary axle box 4 is connected with removable pivoted arm 2 by bolt, and pivoted arm 2 outer ends are fixed with by bolt and measure gauge stand 3.Be evenly equipped with three threaded holes on 120 ° of directions of external arc of locating sleeve 5, locating sleeve is by the jackscrew 7 and newel 1 locking positioning of 3 M12.
Principle of work of the present utility model is as follows: when needs during in out frame internal diameter water detection Pingdu, dial gauge is installed on the measurement gauge stand 3 of this measurement bay pivoted arm outer end, length (because length size difference of every positioning bar) according to positioning bar, move up and down locating sleeve 4 to correct position, jackscrew on the screwed in place cover 4 can be with locating sleeve 4 and newel 1 locking positioning.Rotation rotary axle box 4 is measured the support lower ring plate, can measure the nonparallelism of ring flat-plate and positioning bar.For the ring flat-plate of different radii, can realize measuring by the pivoted arm 2 of changing different size.
