Description

The tooth support drilling tools of using more

Technical field

The utility model belongs to a kind of drilling tool, particularly relates to a kind of tooth support drilling tool of using more.

Background technology

The stator of hydrogenerator is the key component of whole unit, and its quality directly affects the life-span of unit.And the quality of stator quality directly depends on the quality of stator core.Stator core is made up of punching, stretching screw, tooth support etc.The folded sign indicating number of punching back compresses punching by stretching screw and tooth support.Because of stretching screw will pass the tooth support at two ends and the hole in the middle punching simultaneously, therefore require the axis in hole on punching, the tooth support on same axis, the position punch die in hole guarantees in the punching, Kong Yaoyong on the tooth support makes up mold or guarantees with drilling tool, only in this way could guarantee assembling.Adopt at present usually the boring tire that tooth support is holed, when using boring awl hole, tooth support of every brill will be moved twice and bore tire, repeat simultaneously to workpiece centering, operation such as compress; Especially when boring the tire weight, also will by suspender bring many inconvenience, and inefficiency, labour intensity are big to production.

Summary of the invention

The utility model for solving the tooth support drilling tools of using that the technical problem that exists in the known technology provides a kind of simple in structure, easy to use, province that saves time, increases work efficiency more.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:

A kind of tooth support drilling tool of using more, it is characterized in that: comprise base, be processed with several screws on the base, the back-up block of installing by securing member on the base, back-up block is provided with drill jig, drill jig is provided with alignment pin, and drill jig is fastened on the back-up block by pinching screw, and the lower end of base is equipped with cushion block by securing member, the right side of cushion block is equipped with housing screw, be set with pressing plate on the housing screw, the lower surface of cushion block is equipped with gripper shoe by securing member, is equipped with on the gripper shoe and holds out against screw.

Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, being about to the disposable location and installation of base on the workbench of lathe, save in operation in the past the moving of boring mold, thereby save man-hour, reduce labor intensity of operating personnel.Behind the fixed head location, utilize the drill jig that is packed on the back-up block to hole, drill jig is provided with alignment pin, can realize the quick location of workpiece when boring, significantly reduces preparations such as location before boring, centering.Therefore said structure is simple, easy to operate, time saving and energy saving and improved operating efficiency greatly.
