As shown in figure 5, by cuboid C23 from positioning principle demonstration part take away, it is assumed that to process rectangular channel B20 and
The part that cuboid C23 is engaged, understands to need to limit 6 frees degree by analysis, now needs to place 3 in XOY plane 2
Supporting nail, 2 supporting nails are placed in YOZ planes, are placed a supporting nail in XOZ planes 1, are thus demonstrated to the complete of workpiece
Full positioning.If now placing a supporting nail less in arbitrary plane, it is possible to deficient positioning of the demonstration to workpiece.
As shown in fig. 6, cuboid A21 or cuboid B22 and cuboid C23 is taken away from positioning principle demonstration part, this
When assume to process rectangular channel B20, by analysis understand need limit 5 frees degree, now need XOY plane 2 place 3
Supporting nail, places 2 supporting nails in YOZ planes 3, thus demonstrates the incomplete positioning to workpiece.
If as shown in fig. 7, to process heart axle B14 external cylindrical surface, now heart axle B14 is placed on plane XOY2,
Long heart axle C17 is penetrated in heart axle B14 center hole B16, now equivalent to plane XOY2 limit heart axle B14 around X and Y
The rotation of axle, 3 frees degree that move along Z axis, long heart axle C17 limit heart axle B14 moving, around X and Y-axis along X and Y-axis
4 frees degree of rotation, can now demonstrate to workpiece cross position.
When heart axle A13 is regarded as workpiece, when being positioned using V-block A9；Heart axle B14 is regarded as workpiece, using V-block B10
During positioning；When heart axle A13 is regarded as workpiece, when being positioned using semicircle orifice A11；When heart axle A13 is regarded as workpiece, using semicircle orifice
When B12 is positioned；When heart axle C17 is regarded as workpiece, when being positioned using circular hole A15 or circular hole B16；Workpiece locating surface, which can be demonstrated, is
Positioning during external cylindrical surface.
When circular hole A15 is regarded as workpiece, when being positioned using heart axle C17；When circular hole B16 is regarded as workpiece, using heart axle C17
During positioning, positioning when workpiece locating surface is circular hole can be demonstrated.
A kind of principle of six-point fixing demonstration teaching aid of the utility model, can with ocular demonstration principle of six-point fixing, completely positioning,
Not exclusively positioning, owe positioning, cross positioning and representative workpiece locating surface positioning, allow student to representative workpiece locating surface, often
With setting element have deeper into understanding, more intuitively understand and grasp principle of six-point fixing, distinguish positioning and clamp area
Other and contact, carries out Machine Tool Fixture Design to student and establishes good basis.
