Abstract
A measuring device for measuring and inspecting various linear dimensional properties of a machined groove in a workpiece includes a fixing base, a measuring assembly, and first and second positioning members received through and protruding from the fixing base at right angles during the movement of the measuring assembly. The measuring assembly includes a measuring member, a shim, and an elastic member, the shim sleeves on an end of the measuring member, and the elastic member resists between the shim and the fixing base. The measuring assembly, together with the first positioning member and the second positioning member, enable the required depth and relative position of the machined groove to be accurately determined and inspected.
Claims20
A measuring device for inspecting dimensional properties of a machined groove in a workpiece relative to a side wall of the workpiece, the workpiece further comprises a bottom wall connected with the side wall, the groove is defined in the bottom wall and cooperative defined by a curved bottom surface in three dimensions, a first connecting surface, and a second connecting surface, the second connecting surface is located oppositely to the first connecting surface and connected to the first connecting surface via the bottom surface, the second connecting surface abuts the side wall of the workpiece, and the measuring device comprising:
- a fixing base,
- a measuring member movably assembled to the fixing base along a first direction;
- a first positioning member and a second positioning member received through and protruding from the fixing base at as same side of the fixing base along a second direction substantially perpendicular to the first direction, the first positioning member being spaced from the second positioning member,
- wherein the first positioning member resists against the bottom surface and the first connecting surface, and the second positioning member resists against the bottom surface, when the measuring member is forced to move along a first direction until a bottom of the measuring member attaches to a top of side wall, the position of the groove relative to the side wall of the workpiece has thereby deemed to be of desired machining quality.
A measuring device for measuring and inspecting dimensional properties of a machined groove in a workpiece, the measuring device comprising:
- a fixing base,
- a measuring assembly telescopically received through the fixing base along a first direction, wherein the measuring assembly comprises a measuring member, a shim, and an elastic member, the measuring member movably passes through the fixing base, two ends of the measuring member protrude from the fixing base, the shim sleeves on an end of the measuring member, and the elastic member resists between the shim and the fixing base;
- and
- a first positioning member and a second positioning member received through and protruding from the fixing base during moving of the measuring assembly, the first positioning member spaced from the second positioning member, wherein the measuring assembly together with the first positioning member and the second positioning member, enable the required depth and relative position of the machined groove to be accurately determined.
