Present invention is disclosed a kind of rotatable clamp for annulus class drilling part, this rotatable clamp structure is simple, clamping workpiece convenient, not only can meet the clamping requirement to different inner diameters annular workpieces Drilling operation, and greatly improve machining accuracy and the working (machining) efficiency in hole.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of the embodiment of the present invention for the rotatable clamp of annulus class drilling part;
In accompanying drawing, the mark of each parts is as follows: 1, Rotatable indexing dish, 2, clamp nut, 3, slotted pressure plate, 4, float centrih axle sleeve, 5, studs, 6, base, 7, pressure bearing, 8, pad, 9, spring, 10, turning handle, 11, locating hole, 12, alignment pin, 13, workpiece.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Fig. 1 is the structural representation of the embodiment of the present invention for the rotatable clamp of annulus class drilling part; The structure of this rotatable clamp comprises: Rotatable indexing dish 1, clamp nut 2, slotted pressure plate 3, float centrih axle sleeve 4, studs 5 and base 6, described Rotatable indexing dish 1 is connected with base 6 by pressure bearing 7, and described clamp nut 2, slotted pressure plate 3, float centrih axle sleeve 4 and Rotatable indexing dish 1 are chained together by studs 5.
The rotatable clamp for annulus class drilling part that the present invention mentions for core component, by selecting multiclass Rotatable indexing dish, can meet the clamping requirement of 4 hole annular workpieces, 6 hole annular workpieces and 8 orifice ring shape work pieces process with Rotatable indexing dish 1.Wherein, Rotatable indexing dish 1 relies on pressure bearing 7 to realize relatively rotating between base 6, and some grooves have been opened on its surface, in order that smooth chip removal in drilling process, has driven the locating hole 11 of respective numbers and positioned by alignment pin 12 below it.When processing 4 hole annular workpieces, the Rotatable indexing dish in 4 groove 4 holes can be selected; When processing 6 hole annular workpieces, the Rotatable indexing dish in 6 groove 6 holes can be selected; When processing 8 hole annular workpieces, the Rotatable indexing dish in 8 groove 8 holes can be selected.The side of this Rotatable indexing dish 1 is provided with turning handle 10, rotation Rotatable indexing dish 1 can be adjusted by regulating rotary fixed handle 10 and reach corresponding angle, then positioned by alignment pin 12, thus realize the rotation of workpiece fixed angle in the clamp state.
