Description
Technical field
The utility model is related to the technology of field of machining " small for mouth and large for cavity " class cast housing inner cavity centering, specially one
Gib head gauge stand of the kind for centering " osculum " housing cavity benchmark.
Background technology
The casting long shell for frequently encountering " small for mouth and large for cavity " in process of production has stringent want to the uniformity of wall thickness
Ask, therefore benchmark is all in housing cavity, due to housing cavity sandbox be linked to be after section multistage core box made of, there are certain
Manufacturing and positioning errors, and the irregular deformation that itself shrinkage or subsequent heat treatment generate after shell cast molding can all influence
The quality of product.
It processes in the shells production process, typically by wall-thickness measurement value after roughing outer circle, further according to wall thickness value
It is adjusted processing, ensures shell uniform wall thickness.But during actual processing, to ensure shell uniform wall thickness, technique base
Standard is in housing cavity, and in centering housing cavity, existing centering mode is by more piece extension bar by indicator bracket to benchmark
At face, the gauge head of dial gauge is in direct contact reference plane, in centering " small for mouth and large for cavity " shells inner cavity benchmark, due to shell mouth
Portion is small, and dial gauge can not observe that table jumps situation after cannot be introduced into or entering, can only be using both ends oral area inner cavity as roughing standard centering
Processing, can not take into account inner cavity middle section, after roughing, cause shell evenness of wall thickness very poor, and borrow amount by wall-thickness measurement
Allowance is again insufficient when adjustment, leads to product rejection, causes prodigious economic loss.
