Description

Surface grinding machine processes the fixture of dovetail key dovetail face
Technical field
The present invention relates to the fixture used in process of metal working, specifically a kind of surface grinding machine processes dovetail key swallow The fixture of tail surface.
Background technology
A little permanent magnet generators design oat tail groove structure in rotor core, for installing permanent magnet.Permanent magnet passes through dovetail Structure is fixed in rotor core.Due to the gap very little between permanent magnet dovetail face and rotor core dovetail groove, this is just to turning Sub- iron core laminate precision and to laminate quality requirement very high.Dovetail key is to ensure to laminate precision when laminating and laminate the work of quality Dress, the machining accuracy and processing quality of dovetail key determine the precision and quality of rotor core.The processing of dovetail key dovetail face is The processing difficulties of dovetail key.
Invention content
In view of the above-mentioned problems, providing a kind of fixture of surface grinding machine processing dovetail key dovetail face, which can have the present invention Effect improves the machining accuracy and processing efficiency of dovetail key dovetail face.
Technical solution according to the invention:A kind of fixture of surface grinding machine processing dovetail key dovetail face, it is characterized in that:Including The identical locating piece of at least two structures, the locating piece are arranged in regulates alignment pin, are provided tiltedly on each locating piece Positioning surface is equipped with skewed slot in the lower end of positioning surface, is equipped with straight pin beside skewed slot, forms workpiece dress between positioning surface and straight pin Station is pressed from both sides, locating piece is fixedly arranged at the front end with pressing plate, angularly disposed on pressing plate to have clamping screw, the body of rod and the positioning surface of clamping screw to protect It holds vertical.
As a further improvement on the present invention, it is fastenedly connected by screw between the pressing plate and locating piece.
As a further improvement on the present invention, there are three the regulates alignment pins, three regulates alignment pin triangular shapes Arrangement.
As a further improvement on the present invention, the height of the pressing plate and the height of locating piece are identical, and pressing plate lower end with Positioning block bottom holding flushes.
The technical effects of the invention are that:Product structure advantages of simple of the present invention, can effectively improve swallow in use The machining accuracy of tail key dovetail face, and processing efficiency can be improved simultaneously.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the left view of Fig. 1.
Specific implementation mode
The specific implementation mode of the present invention is further described below in conjunction with the accompanying drawings.
In Fig. 1,2, including locating piece 1, positioning surface 1-1, regulates alignment pin 2, clamping screw 3, straight pin 4, dovetail key 5, Pressing plate 6, skewed slot 7 etc..
As shown in Figure 1, 2, the present invention is a kind of fixture of surface grinding machine processing dovetail key dovetail face, including at least two knots The identical locating piece 1 of structure, the locating piece 1 are arranged in regulates alignment pin 2, and positioning surface is provided tiltedly on each locating piece 1 1-1 is equipped with skewed slot 7 in the lower end of positioning surface 1-1, and 7 side of skewed slot is equipped with straight pin 4, shape between positioning surface 1-1 and straight pin 4 At clamping workpiece station, locating piece 1 is fixedly arranged at the front end with pressing plate 6, angularly disposed on pressing plate 6 to have clamping screw 3, clamping screw 3 The body of rod is vertical with positioning surface 1-1 holdings.
It is fastenedly connected by screw between pressing plate 6 and locating piece 1;There are three the regulates alignment pins 2, and three adjust positioning 2 triangular shape of pin is arranged;The height of the pressing plate 6 is identical as the height of locating piece 1, and 6 lower end of pressing plate and 1 lower end of locating piece Holding flushes.
Locating piece 1 in the present invention is for controlling the angle of dovetail key dovetail face and the size of dovetail face sharp corner, simultaneously It is reserved on locating piece 1 and measures position, facilitate in-process measurement;Regulates alignment pin 2 is mainly used for the length of alignment jig, To adapt to processing different length workpiece(Dovetail key 5)Demand;Clamping screw 3 prevents workpiece sideslip for clamping workpiece.Dovetail Key 5 is placed on the positioning surface 1-1 of locating piece 1, and clamping screw 3 compresses dovetail key 5, then is ground dovetail key swallow with surface grinding machine Tail surface, after after side, dovetail face is ground, turn-over, grinding other side dovetail face.
In clamping workpiece, 5 bottom surface of dovetail key fits on positioning surface 1-1 product of the present invention, the lateral support of dovetail key 5 It is contacted on straight pin 4, forming line.After long-term use, rotational circle pin 4 can replace determining of having worn out to product of the present invention Plane;Manufacturing procedure processes the burr left before skewed slot 7 can be avoided, and processing efficiency is promoted.
The above described is only a preferred embodiment of the present invention, be not intended to limit the present invention in any form, it is all It is that any simple modification, equivalent change and modification made by above example are still fallen within according to the technical essence of the invention In the range of technical solution of the present invention.
