Abstract
The utility model relates to the field of a processing clamp, in particular to a clamp for processing a steam turbine shroud band. The clamp comprises a bracket, a base, a pressure plate, a screw bolt and a nut. A locating slot is arranged on the base. The base is rotationally connected with the bracket. One end of the screw bolt is fixed on the base. The pressure plate and the base are two discs with the same diameter. The pressure plate is hollow. The edge of the base is provided with breaches. The pressure plate is arranged above the base. Both the pressure plate and the base are respectively provided with two locating slots which are corresponded up and down. A locating bolt bar is arranged on the bracket. An internal and an external shroud bands are firstly rolled into a circle to ensure that the shroud bands do not deform, and are then fixed in the clamp to be processed synchronically. The clamp is simple and convenient, completes forming in one time, and has comparatively high precision.
Description
Technical field
The utility model relates to the clamp for machining field, especially a kind of steam turbine shroud clamp for machining.
Background technology
The steam turbine shroud is a vitals in the steam turbine, plays a part fixed blade.The quality of its crudy directly influences the stability of blade, remote-effects Efficiency of Steam Turbine.The instrument of in the past processing shroud is a punch press, is shroud is directly being gone out the hole of type one by one on the shroud with the shroud punching die on the punch press, will roll up circle on furling plate round machine towards the shroud in good type hole again.Shroud towards good type hole is rolled up circle again, and the type pore volume is yielding, the correction of need polishing during welding, and labour intensity is big, and the efficient low quality is poor, and blade connects unstable.The shortcoming of this complete equipment is, the cost height, and complex procedures, the product precision is low.
The utility model content
In order to overcome existing shroud machining tool cost height, the deficiency that precision is low, the utility model provides a kind of steam turbine shroud clamp for machining.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of steam turbine shroud clamp for machining, comprise support, base, pressing plate, screw bolt and nut, base is provided with locating slot, base is rotatably connected on support, one end of bolt is fixed on the base, and pressing plate and base are the disk of two same diameter, pressing plate hollow, base edge is provided with breach, and support is provided with fastening screw.
Pressing plate is positioned at base top, and both respectively are provided with the twice locating slot, and corresponding up and down.
The degree of depth of locating slot is 4mm.
Even four through holes that distribute on the pressing plate disc, and through hole is on the center line of two locating slots.
The quantity of bolt is four, is evenly distributed on the disc of base, and is on the center line of two locating slots.
The beneficial effects of the utility model are, earlier inside and outside shroud roll ups circle on furling plate round machine, guarantee not out of shapely, are placed in the anchor clamps again and fix, and it is carried out synchronous processing.Simple and convenient, one-shot forming, precision is higher.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a schematic diagram of the present utility model;
Fig. 2 is a side view of the present utility model.
1. supports among the figure, 2. base, 3. pressing plate, 4. bolt, 5. nut, 6. fastening screw.
The specific embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As Fig. 1 is structural representation of the present utility model, a kind of steam turbine shroud clamp for machining, comprise support 1, base 2, pressing plate 3, bolt 4 and nut 5, base 2 is provided with locating slot, base 2 is rotatably connected on support, one end of bolt 4 is fixed on the base 2, pressing plate 3 and base 2 are the disk of two same diameter, pressing plate 3 hollows, base 2 edges are provided with breach, support 1 is provided with fastening screw 6. pressing plates 3 and is positioned at base 2 tops, and both respectively are provided with the twice locating slot, and corresponding up and down, the degree of depth of locating slot is four through holes that evenly distribute on 4mm. pressing plate 3 discs, and through hole is on the center line of two locating slots. the quantity of bolt 4 is four, is evenly distributed on the disc of base 2, and is on the center line of two locating slots.
As Fig. 2 is side view of the present utility model, and the bottom is a support 1, and support 1 is provided with base 2 and fastening screw 6, one end of bolt 4 is fixed on the base 2, the other end penetrates the through hole of pressing plate 3, just can firmly shroud be sandwiched in the middle of base 2 and the pressing plate 3 processing of progressive type hole after tightening with nut 5.
Bored earlier the through wires hole of fixed knot distance during use on inside and outside shroud, with the breach of fastening screw 6 insertion bases 2, the base 2 that can rotate around the center of circle has been fixed with support 1, support 1 is fixed on the wire cutting machine tool again.Inside and outside shroud is embedded respectively in two locating slots of base 1 then, and make a pair of through wires hole on the inner and outer ring in the radial direction same.Pressing plate 3 is covered the top at inside and outside shroud again, and guarantee that the upper edge of inside and outside shroud embeds respectively in two locating slots of pressing plate 3, four bolts 4 insert through hole, and the tight back of lid fastening nut 5 is fixed.At last the molybdenum filament of wire cutting machine tool is passed a pair of through wires hole on the inside and outside shroud, the type hole on the inside and outside shroud of processing simultaneously.Process a pair of after, turnable base, adjusting position, processing is down a pair of.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
