Abstract
The present invention is that one kind makes plane positioning be more convenient reliable casting location structure in processing.The master reference of casting is the facet in three of the big in-plane pit of casting not equal parts, it first must three support column centering casting master references can clamping processing on oild chuck when processing, it can only be with manual feeling, being repeated as many times installation sometimes can be in place, now master reference is transferred on external disk, because there are casting pattern drafts for disk, two inclined-planes are formed along die joint, disk is now changed to circular conical surface, from circumferential edge to central protuberance, remain pattern draft, keep each point height on each concentric circles consistent, support column expands outward, it can one-time-reach-place when installation, it positions also reliable and stable.
Description
Technical field
Foundary industry casting sand mold die joint reserves the formative method of pattern draft.
Background technique
The turbocharger middle body of Honeywell Corp. USA such as 804153 all marks on drawing and reserves original base
Quasi- size and position is that three approximate trisections are reserved on the small conical surface that one middle side part of compressor is recessed in plane positioning
Facet, bearing area only hasCasting in processing toward when installing on numerically controlled lathe oild chuck, can only be with the feeling of hand
Going for positive casting master reference can be processed in the position of three support columns of chuck.Sometimes in place through claw clamping one
Rotation discovery is shaken too much, is would have to release claw and is reinstalled centering, although seeming sometimes can process, inside is accidentally
Difference is still very big.This kind of casting work in-processes are influenced by Set and Positioning with very big, not only machined surface and non-processing face position
Precision is unstable, also interferes the raising of processing efficiency.
Summary of the invention
The present invention is that one kind makes plane positioning be more convenient reliable casting location structure in processing.By casting master reference
From three facets on the lesser pit conical surface, it is transferred in external big plane and sets up technological datum, equal part is become into equal part.
The technical scheme is that the master reference outer ring plane of casting is reserved with 2-3 ° using die joint as starting point
Pattern draft, to plane formed two inclined-planes, can not three-point fix, now will circle inclined-plane be changed to circular conical surface, the gradient still retains, from
Disk, to central protuberance, keeps the height on each concentric circles consistent along side.
Remarkable result of the invention is that circumference can be expanded to nearly circular cone planar perimeter by the supported at three point column on chuck, makes three
Spot placement accuracy improves, and any circumference can position in plane, makes simple installation that can once not only increase the steady of positioning accuracy
It is qualitative, also improve casting installation efficiency when processing.
Detailed description of the invention
Fig. 1 casting installs positioning cross-sectional view on numerically controlled lathe oild chuck
The right view of Fig. 2 Fig. 1
1, casting 2, master reference 3, technological datum 4, circular conical surface
Specific embodiment
One kind makes plane positioning be more convenient reliable casting location structure in processing.The master reference 2 of casting 1 is transferred to
On 3 position of technological datum of conical plane 4, conical plane 4 remains pattern draft, the position of oild chuck positioning support column
Setting may be selected close to 4 edge of conical plane, then be clamped with oild chuck.
Claims (1)
1. a kind of make plane positioning be more convenient reliable casting location structure in processing, it is characterized in that: the master reference of casting
It is transferred on the technological datum position of conical plane, conical plane remains pattern draft, oild chuck positioning support column
Position may be selected close to conical horizontal edge, then clamped with oild chuck.
