Abstract
The invention relates to a clamp used during the metal processing process, in particular to a clamp for processing a dovetail key dovetail surface by a plane grinding machine. The clamp comprises at least two positioning blocks identical in structure, wherein the positioning blocks are arranged on an adjusting positioning pin in a penetrating manner, each positioning block is obliquely provided with a positioning surface, a chute is formed in the lower end of the positioning surface, a cylindrical pin is arranged by the side of the chute, a workpiece installation workstation is formed between the positioning surface and the cylindrical pin, a pressure plate is fixed on the front end of the positioning block, a locking bolt is obliquely arranged on the pressure plate, and a rod body of the locking bolt is perpendicular to the positioning surface. The clamp is simple and reasonable in structure, capable of effectively improving the processing efficiency of the dovetail key dovetail surface in the application process and also capable of improving the machining efficiency.
Description
Technical field
The present invention relates to the fixture used in process of metal working, specifically a kind of fixture of surface grinding machine processing dovetail key dovetail face.
Background technology
A little magneto designs oat tail groove structure in rotor core, for installing permanent magnet.Permanent magnet is fixed in rotor core by dovetail configuration.Because the gap between permanent magnet dovetail face and rotor core dovetail groove is very little, this just to rotor core laminate precision and to laminate quality requirement very high.Dovetail key ensures the frock laminating precision and laminate quality when being and laminating, the machining accuracy of dovetail key and crudy determine precision and the quality of rotor core.The processing of dovetail key dovetail face is the processing difficulties of dovetail key.
Summary of the invention
The present invention is directed to the problems referred to above, provide a kind of surface grinding machine to process the fixture of dovetail key dovetail face, this fixture effectively can improve machining accuracy and the working (machining) efficiency of dovetail key dovetail face.
According to technical scheme of the present invention: a kind of fixture of surface grinding machine processing dovetail key dovetail face, it is characterized in that: comprise the locating piece that at least two structures are identical, described locating piece is arranged in and regulates on alignment pin, each locating piece all tilts to be provided with locating surface, skewed slot is provided with in the lower end of locating surface, skewed slot side is provided with straight pin, clamping workpiece station is formed between locating surface and straight pin, locating piece front end is fixed with pressing plate, obliquely on pressing plate be provided with clamping screw, the body of rod and the locating surface of clamping screw keep vertical.
As a further improvement on the present invention, described pressing plate is connected by screw fastening with between locating piece.
As a further improvement on the present invention, described adjustment alignment pin has three, and three adjustment alignment pin shapes triangular in shape are arranged.
As a further improvement on the present invention, the height of described pressing plate is identical with the height of locating piece, and pressing plate lower end and locating piece lower end keep flushing.
Technique effect of the present invention is: product structure advantages of simple of the present invention, in use effectively can improve the machining accuracy of dovetail key dovetail face, and can improve working (machining) efficiency simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the left view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
In Fig. 1,2, comprise locating piece 1, locating surface 1-1, regulate 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 the fixture of a kind of surface grinding machine processing dovetail key dovetail face, comprise the locating piece 1 that at least two structures are identical, described locating piece 1 is arranged in and regulates on alignment pin 2, each locating piece 1 all tilts to be provided with locating surface 1-1, skewed slot 7 is provided with in the lower end of locating surface 1-1, skewed slot 7 side is provided with straight pin 4, clamping workpiece station is formed between locating surface 1-1 and straight pin 4, locating piece 1 front end is fixed with pressing plate 6, obliquely on pressing plate 6 be provided with clamping screw 3, the body of rod and the locating surface 1-1 of clamping screw 3 keep vertical.
Be connected by screw fastening between pressing plate 6 with locating piece 1; Described adjustment alignment pin 2 has three, and three adjustment alignment pin 2 shapes triangular in shape are arranged; The height of described pressing plate 6 is identical with the height of locating piece 1, and pressing plate 6 lower end keeps flushing with locating piece 1 lower end.
Locating piece 1 in the present invention is for the size of the angle and dovetail face sharp corner that control dovetail key dovetail face, and reserved measuring position on locating piece 1, facilitates in-process measurement simultaneously; Alignment pin 2 is regulated to be mainly used in the length of alignment jig, to adapt to the demand of processing different length workpiece (dovetail key 5); Clamping screw 3, for clamping work pieces, prevents workpiece sideslip.Dovetail key 5 is placed on the locating surface 1-1 of locating piece 1, and dovetail key 5 compresses by clamping screw 3, then uses surface grinding machine grinding dovetail key dovetail face, after side dovetail face grinding is good, and turn-over, grinding opposite side dovetail face.
Product of the present invention is when clamping workpiece, and dovetail key 5 bottom surface fits on locating surface 1-1, and the lateral support of dovetail key 5, on straight pin 4, forms linear contact lay.After long-term use, rotational circle pin 4 can change the locating surface of experience wear to product of the present invention; Skewed slot 7 can avoid before manufacturing procedure process the burr stayed, working (machining) efficiency promotes to some extent.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
