Abstract
The utility model relates to a be used for hot jacket iron core support ring with straight key, unable adjustment base (1) is advanced line location with clamp plate (2) through locating pin (4) and is fixed, nut (9) on clamp plate (2) are used for adjusting the tightly stroke of piece (3) that expands, threaded connection is passed through with screw (5) in nut (9), expand tight piece (3) through inclined plane and unable adjustment base (1) and clamp plate (2) contact, expand tight piece (3) symmetric distribution in clamp plate (2) both sides, extension spring (6) both ends are connected respectively on the tight piece (3) that expands of both sides, through expand tight piece (3) the take -up of extension spring (6) with both ends. This is novel to have the dismouting of being convenient for advantage to the operating procedure obtains simplifying and avoided because of using the clamp to lead to stator core (7) excircle surface fish tail.
Description
Technical field
This novel one that relates to is for the hot jacket straight key of iron core support ring.
Background technology
Stator core hot jacket support ring generally uses general flat key to position, and one end is inserted in stator core keyway, extension
Demultiplexing positions iron core support ring, but due in stator core keyway can not thread mill drilling, so flat key is fixing highly difficult,
General using steel band around stator core cylindrical one week, and be fixed with clip, this fixed form, the dismounting of key is the most not
Convenient, and during steel band banding, easily scratch stator core outer round surface.
Summary of the invention
This novel purpose is to provide a kind of for the hot jacket straight key of iron core support ring, it is possible to effectively solve iron core during hot jacket
The problem of positioning key fixing difficulty during support ring.This novel technical scheme is: a kind of for the hot jacket straight key of iron core support ring,
Firm banking (1) is fixed on the positioning by alignment pin (4) with pressing plate (2), and the nut (9) on pressing plate (2) is used for adjusting swelling
The stroke of block (3), nut (9) is threaded connection with screw (5), and expanding block (3) is by inclined-plane and firm banking (1) and pressure
Plate (2) contacts, and expanding block (3) is symmetrically distributed in pressing plate (2) both sides, and extension spring (6) two ends are connected to the expanding block (3) of both sides
On, by extension spring (6), the expanding block (3) at two ends is strained.
The planform of expanding block (3) is: symmetrical ramp structure, the position of intersecting point on inclined-plane extends one section of gusset, muscle
With being used for hiding screw (5) and the waist hole of alignment pin (4), the through hole of installation extension spring (6) on plate.
Four holes being distributed on firm banking (1) and alignment pin (4) external diameter interference fit, four holes on pressing plate (2)
With alignment pin (4) external diameter interference fits, position relative with hole, firm banking (1) inclined-plane, both sides and pressing plate (2) inclined-plane, both sides with
The relative position in hole is completely the same.
This Novel work principle:
Four holes being distributed on firm banking (1) and alignment pin (4) external diameter interference fit, four holes on pressing plate (2)
With alignment pin (4) external diameter interference fits, position relative with hole, firm banking (1) inclined-plane, both sides and pressing plate (2) inclined-plane, both sides with
The relative position in hole is completely the same, and when tightening nut (9), pressing plate (2) is guided by four alignment pins (4), and pressing plate (2) is with solid
Determine base (1) and jointly extrude the inclined-plane coordinated with expanding block (3), moving to two ends of expanding block (3) uniformity.
This Novel work process:
First 4 nuts (9) on screw (5) being unclamped, both sides expanding block (3) is tensioned to two ends to centre by extension spring (6)
The width of expanding block (3) is less than stator core (7) width of keyway, and straight key puts into keyway, tightening nut (9) along with two ends
The movement of expanding block (3), is finally pressed on stator core (7) keyway inwall, and hot jacket iron core support ring (8), by the fixing end
The part that seat (1) stretches out outside stator core (7) keyway positions with iron core support ring (8) keyway, unclamps screw after cooling
(5) nut (9) on, expanding block (3) is reduced by extension spring (6) tension, two expanding blocks (3) spacing, is taken off straight key and complete iron core
Support ring (8) hot jacket operation.
Basis is the most novel to be had the advantages that
This is the most novel has and is easy to dismount advantage, and the stroke of regulation expanding block (3) needs to be realized by adjusting nut (9),
Compare and use the mode that fixes for one week around stator core (7) cylindrical of clip, operating procedure be simplified and avoid because of
Clip is used to cause stator core (7) outer round surface to scratch.

Detailed description of the invention
One as shown in Figure 1 is used for the hot jacket straight key of iron core support ring, and firm banking 1 and pressing plate 2 are by alignment pin 4
Being fixed on the positioning, as in figure 2 it is shown, the nut 9 on pressing plate 2 is used for adjusting the stroke of expanding block 3, nut 9 and screw 5 pass through spiral shell
Stricture of vagina connects, as it is shown on figure 3, expanding block 3 is contacted with firm banking 1 and pressing plate 2 by inclined-plane, expanding block 3 is symmetrically distributed in pressing plate 2
Both sides, extension spring 6 two ends are connected on the expanding block 3 of both sides, are strained by the expanding block 3 at two ends by extension spring 6.
As shown in Figure 4, the planform of expanding block 3 is: symmetrical ramp structure, the position of intersecting point on inclined-plane extends one section
Gusset, with being used for hiding the waist hole of screw 5 and alignment pin 4, installing the through hole of extension spring 6 on gusset.
As shown in Figure 4, four holes being distributed on firm banking 1 and alignment pin 4 external diameter interference fit, four on pressing plate 2
Individual hole and alignment pin 4 external diameter interference fits, position relative with hole, inclined-plane, firm banking 1 both sides and inclined-plane, pressing plate 2 both sides and hole
Relative position completely the same.
