Abstract

The utility model relates to the field of a power generator, in particular to a stator inner hole expansion clamp for machining a conventional power generator stator. The stator inner hole expansion clamp comprises a rotation expansion body (1), a locating mould (2), a tight pressing locking piece (3), an expansion sleeve (4) and a fastening bolt (5). The stator inner hole expansion clamp is characterized in that the rotation expansion body (1) is fastened with the locating mould (2) which is of a circular ring shape, the ring-shaped plane is tightly attached to the rotation expansion body (1), the expansion sleeve (4) is arranged inside a workpiece to be machined, the rotation expansion body (1) is sleeved with the expansion sleeve (4) and the workpiece to be machined, wherein the expansion sleeve (4) and the workpiece to be machined form a whole, and the circular ring plane of the expansion sleeve (4) tightly leans against the locating mould (2), and the tight pressing locking piece (3) and the fastening bolt (5) lock the expansion sleeve (4). The stator inner hole expansion clamp has the advantages that uniformity of products can be excellently guaranteed when the outer circle of the stator is machined, the products can be rapidly clamped, working efficiency of workers is greatly improved, and the stator inner hole expansion clamp is suitable for mass production operation of factories.

Description

A kind of stator inner hole expansion anchor clamps
Technical field
The utility model relates to electrical generator fields, particularly relates to the stator inner hole expansion anchor clamps that the machined of conventional power generation usage machine stator is used, and also can be used for annular parts outer circumference surface dimensioned.
Background technology
All the time can not guarantee the form and position tolerances such as the circularity of stator internal and external circumference and axiality in the processing of electrical generator fields stator excircle and both sides end face, this relates to some fixture technologies in machined field, the processing of especially annular parts periphery, the circularity of periphery can not be well controlled all the time, the perpendicularity of the planar annular of circular parts and inner periphery can not control to and size accurately in addition, common clamping method is for to divide anchor ring to process with the scroll chuck holding part on the lathe, also have in addition other method clamping method, but all can not well guarantee the above-mentioned tolerance and size of mentioning.
The utility model content
The purpose of this utility model is to provide a kind of stator inner hole expansion anchor clamps, overcomes the following problem of bringing of existing traditional mold: can not well guarantee circularity and axiality during the annular parts inside and outside circle side face of (1) processing.(2) processing annular element two annular end faces are bigger than normal to the perpendicularity form and position tolerance of periphery.(3) the parts clamping is loaded down with trivial details with dismounting.
For achieving the above object, the technical solution of the utility model is as follows: a kind of stator inner hole expansion anchor clamps comprise and turn round the body (1) that rises, positioning clamping fixture (2), hold out against locking plate (3), ringfeder (4) and fastening bolt (5) is characterized in that:
Rise body (1) and positioning clamping fixture (2) of described revolution is fastening; Described positioning clamping fixture (2) is annular, and planar annular is close to the revolution body (1) that rises; Ringfeder (4) is to be processed inside, and ringfeder (4) is enclosed within to be processed integral body and turns round on the body (1) that rises, and the circular planes of ringfeder (4) abuts against on the positioning clamping fixture (2); Hold out against locking plate (3) and fastening bolt (5) locking ringfeder (4).
Further, described positioning clamping fixture (2) is circular, and periphery is the conical surface, and inner headed face is two sections faces of cylinder that size is different.
Further, the described locking plate (3) that holds out against is circular or dish shape, has hollow structure.
The beneficial effects of the utility model are: be used for effectively control generator unit stator excircle dimension, bowlder can be good at guaranteeing the uniformity of product outside the processing stator, and can realize the quick-clamping product, to stator without any damage, improve greatly especially workman's operating efficiency, be applicable to the production in enormous quantities operation of factory.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram.
Fig. 2 is the lock plate structure schematic diagram that holds out against of the present utility model.
Fig. 3 is fastening bolt structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The utility model is a kind of stator inner hole expansion anchor clamps, comprising: turn round the body 1 that rises, positioning clamping fixture 2 holds out against locking plate 3, ringfeder 4, fastening bolt 5.Described revolution body 1 front end that rises is cone boss, and the large end of boss has two sections pillow blocks, is cylindrical-shaped structure behind two sections pillow blocks, and boss small end center is tapped blind hole.Positioning clamping fixture 2 is circular parts, and periphery is the conical surface, and inner headed face is two sections faces of cylinder that size is different.Hold out against locking plate 3 and be circular parts, periphery is the face of cylinder or with the conical surface, inner headed face is two sections faces of cylinder that size is different.Ringfeder 4 is comprised of three identical parts of profile, is external cylindrical surface after the combination, and there are the combined type parts of taper vacancy inside.Fastening bolt (5) is for hexagon-headed bolt makes into, and unnecessary screw thread is fallen in the root Vehicle Processing.
In order to realize the accurate processing of stator periphery, the first step is carried out clamping, locking with lathe chuck to the revolution body 1 rear end axle cylindrical that rises.
Second step is loaded on revolution with positioning clamping fixture 2 by direction as shown and rises on the body 1, and makes planar annular be closely attached on the revolution body 1 that rises.
The 3rd step, ringfeder 4 is put into to be processed inside, its integral body is enclosed within turns round on the body 1 that rises again, circular planes is abutted against on the positioning clamping fixture 2, direction is as shown.
The 4th step will hold out against locking plate 3 by on ringfeder 4 by direction as shown, and lock with fastening bolt 5.
When processing same specification parts in enormous quantities, for realizing quick-clamping, available spanner is unscrewed fastening bolt (5) after initial workpiece workpiece completion of processing, fully demounting bolt, with next parts fixation locking processing, operation can realize quick-clamping and so forth again.
The utlity model has following advantage: 1, can well guarantee the form and position tolerances such as the circularity of Workpiece internal-external circle face and axiality.2, the squareness tolerance of workpiece circular in the face of inside and outside disc can be controlled in the very little scope.3, can realize quick-clamping, enhance productivity greatly.
