Abstract
The utility model discloses a large-scale unit processing guide vane split key pin hole fixing tool, which consists of a fixed pressing plate, a through groove, a threaded through hole, a fixed pressing plate and a gasket, wherein a positioning stud is connected with the fixed pressing plate through the threaded through hole in a screwing mode; the positioning stud penetrates through the gasket and the through groove to be connected with the fixed pressing plate. The utility model has the technical characteristics of easy and simple to handle, the commonality is strong, economic nature is high, effectively promote product quality.
Description
Technical Field
The utility model relates to a machining tool, in particular to processing appurtenance of stator split key pinhole.
Background
In the water turbine set, the guide vane and the guide vane arm are important components in a water distributor of the water turbine, and the guide vane, the guide vane arm and the connecting rod are connected with each other and are opened and closed to guide and cut off water flow and regulate the flow passing through the water turbine, so that the function of controlling the water quantity entering a volute is achieved. Two or three split keys are arranged on the guide vane and the guide vane arm, and in the case of a switch, the key is stressed greatly. And because a semicircle of the key is arranged on the guide vane and the other semicircle is arranged on the guide vane arm, in order to ensure that the key is not influenced to the matching of the guide vane and the guide vane arm in a stressed state, the processing quality of the split key pin hole is very important. When a split key pin hole of a large-diameter deep-hole guide vane is machined, the split key pin hole is often influenced by chip removal, vibration and the like, the problems of scratches, abrasions, groove marks and the like can exist on the surface of the split key pin hole in machining, the machining quality of a split key of the guide vane is influenced, a large amount of time is wasted, higher treatment cost can be generated subsequently, the consumption of manpower and material resources is large, and the delivery cycle of a product is seriously influenced.
Disclosure of Invention
In view of this, the utility model aims at providing an easy and simple to handle, the commonality is strong, economic nature is high, have the processing appurtenance who improves stator split key pinhole quality. The technical scheme of the utility model is that: the positioning device comprises a fixed pressing plate (1), a through groove (2), a threaded through hole (3), a fixed pressing plate (4) and a gasket (5), wherein a positioning stud (4) is connected with the fixed pressing plate (1) through the threaded through hole (3) in a screwing mode; the positioning stud (4) penetrates through the gasket (5) and the through groove (2) to be connected with the fixed pressing plate (1).
Technical effects
1. The utility model discloses a holding plate, gasket are the common instrument of workshop production and part, are convenient for add man-hour stator, stator arm equipment, use at stator split key pin hole, and are easy and simple to handle, and economic nature is high.
2. The utility model is suitable for an in the stator split key pin hole course of working, can realize that the stator is more firm after the combination of guide vane and guide vane arm, the problem that the work piece moved around the cluster, the clearance had the change when solving processing split key guarantees product quality.
3. The utility model discloses can be applied to the processing work of each unit stator split key pinhole on a large scale, the commonality is strong.

Detailed Description
As shown in fig. 1 and 2, the fixing tool for machining the split key pin hole of the guide vane of the large-scale unit comprises a fixing pressing plate 1, a through groove 2, a threaded through hole 3, a fixing pressing plate 4 and a gasket 5, wherein a positioning stud 4 is connected with the fixing pressing plate 1 in a screwing mode through the threaded through hole 3; the positioning stud 4 penetrates through the gasket 5 and the through groove 2 to be connected with the fixed pressing plate 1.
After the guide vane is placed on the V-shaped iron, the guide vane is aligned firstly, leveled and vertically qualified, the guide vane is fixed firmly, a fixed connecting plate and a square box of a guide vane arm are placed according to the position and the size given by a process file, then the guide vane arm, the connecting plate and the guide vane are combined, a fixed pressing plate is placed on the machining end face of the guide vane arm and the guide vane, a screw is screwed and connected with the guide vane and a threaded hole in the guide vane arm through a threaded through hole in the middle of the fixed pressing plate and through grooves in two sides respectively, the guide vane and the guide vane arm are fixed firmly, two workpieces cannot move when a guide vane split key pin hole is machined, and therefore the machining quality and the technical requirements of products of the guide vane split key pin hole are met.
The foregoing has outlined rather broadly the principles and features of the present invention in connection with the accompanying drawings. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by adopting equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
