The deformation correcting device for the large-size bearing ring, which is provided by the utility model, has the characteristics of simple structure and convenient operation, and can ensure the quality of the bearing.
Description
Technical field
The utility model relates to a kind of large size bearing production equipment, more specifically says so to be applied to the means for correcting of wind electricity pitch variable bearings lasso distortion, belongs to machinery manufacturing technology field.
Background technology
Because wind electricity pitch variable bearings has bulky characteristics, the wind electricity pitch variable bearings performance requirement is higher, for satisfying these requirements, bearing ring (comprising outer ring and inner ring) will be through modified and surface induction heat treatment, during particularly for the heat-treating of its lasso, owing to its volume reason can't be heat-treated simultaneously to its integral body, thereby often adopt stepped approach piecemeal.But, because substep when heat-treating piecemeal, cause easily that lasso different parts temperature is different and produce metaboly, have a strong impact on follow-up machining.What therefore, the correction of lasso just showed is quite important.
The utility model content
At above-mentioned situation, the utility model provides a kind of simple in structure, easy to operate large-scale bearing ring distortion means for correcting, to guarantee the quality of bearing.
For achieving the above object, the utility model by the following technical solutions: a kind of large-scale bearing ring distortion means for correcting, it comprises framework, top-pressure mechanism and several backstays of regular polygon, the end of described top-pressure mechanism is provided with fore-set; Be provided with fixture in the described framework, described top-pressure mechanism is fixed on the interior fixture of framework; The framework of described regular polygon has several side columns, one of them side column is for proofreading and correct post, remaining side column is a reference column, described correction post is provided with correction hole, the fore-set of described top-pressure mechanism passes correction hole, described reference column is provided with locating hole, and described backstay passes locating hole and is threaded with reference column by locating hole.
Described fore-set stretches out two terminations that the end face of correction hole has a termination or vertical distribution.Described top-pressure mechanism can be a hydraulic press.The limit of the framework of described regular polygon is 4-10.Described fixture can be arranged on a crossbeam in the framework.
Adopt such scheme, the framework of regular polygon places in bearing outer ring or the inner ring, and the position of outer ring or inner ring distortion is corresponding with the correction post, and the backstay of each reference column is tight against outer ring or inner ring inboard, start top-pressure mechanism, finish the distortion of lasso by fore-set roof pressure outer ring or inner ring inboard and proofread and correct.When proofreading and correct inner ring, adopt the end face that stretches out correction hole to have the fore-set of a termination, when proofreading and correct the outer ring,, therefore, adopt the end face that stretches out correction hole to have the fore-set of two terminations of vertical distribution because the inboard, outer ring has two grooves.In a word, the utility model large-scale bearing ring distortion means for correcting has simple in structure, convenience operation, can guarantee the quality of bearing.
Description of drawings
Fig. 1 is the structural representation of the utility model large-scale bearing ring distortion means for correcting;
Fig. 2 is an example structure schematic diagram of the fore-set end face that stretches out correction hole;
Fig. 3 is another example structure schematic diagram of the fore-set end face that stretches out correction hole.
Among the figure: the framework of 1-regular polygon, the 2-top-pressure mechanism, the 3-fore-set, the 4-fixture, 5-proofreaies and correct post, 6-reference column, 7-correction hole, 8-locating hole, 9-backstay, 10-termination.
The specific embodiment
As shown in Figure 1, large-scale bearing ring of the present utility model is out of shape means for correcting, comprises framework 1, top-pressure mechanism 2 and several backstays 9 of regular polygon, and the limit of the framework 1 of regular polygon is 4-10, and the framework 1 of present embodiment is a regular hexagon.The quantity of backstay 9 mostly is than the quantity on the limit of regular polygon most lacks 1, and the quantity of the backstay 9 of present embodiment is 5, and 3 or 4 backstays 9 can certainly be set.Described top-pressure mechanism 2 can be a hydraulic press.
The end of described top-pressure mechanism 2 is provided with fore-set 3; Be provided with fixture 4 in the described framework 1, described top-pressure mechanism 2 is fixed on the fixture 4 in the framework 1.Described fixture 4 mainly is that top-pressure mechanism 2 is positioned, and can adopt the various fixing means of prior art, and the fixture 4 of present embodiment is arranged on a crossbeam 11 in the framework 1.
The framework 1 of described regular polygon has several side columns, one of them side column is for proofreading and correct post 5, remaining side column is a reference column 6, described correction post 5 is provided with correction hole 7, the fore-set 3 of described top-pressure mechanism 2 passes correction hole 7, described reference column 6 is provided with locating hole 8, and described backstay 9 passes locating hole 8 and is threaded with reference column 6 by locating hole 8.
Referring to Fig. 2, Fig. 3, at the inner ring and the outer ring of proofreading and correct bearing, the end face that described fore-set 3 stretches out correction hole 7 has two terminations 10 of a termination 10 or vertical distribution.When proofreading and correct inner ring, adopt the end face that stretches out correction hole 7 to have the fore-set 3 of a termination 10, when proofreading and correct the outer ring,, therefore, adopt the end face that stretches out correction hole 7 to have the fore-set 3 of two terminations 10 of vertical distribution because the inboard, outer ring has two grooves.
