Abstract
The utility model provides a tool for measuring the width of a groove in a hole. The tool can conveniently and simply measure the tolerance of an oil groove in a workpiece hole, is high in measuring efficiency, and further ensures the processing quality of the oil groove in the workpiece hole. The tool comprises a measuring gauge body, wherein a through hole is arranged on the measuring gauge body, a movable measuring rod is arranged in the through hole, an operation handle is connected with the measuring rod through a long groove, measuring heads are arranged at two ends of the measuring rod, and the diameters of the measuring heads at two ends of the measuring rod are different.
Description
Technical field
The utility model relates to the technical field of measuring the instruments of inspection, is specially groove width measurer in a kind of hole.
Background technology
When being provided with oil groove in workpiece hole, for the fuel feeding that guarantees oil groove is normal, the oil groove width has certain tolerance, and because oil groove is in workpiece hole, very difficult to the measurement of its width, detection efficiency is low, has affected the crudy of workpiece hole inner oil sump.
Summary of the invention
For the problems referred to above, the utility model provides groove width measurer in a kind of hole, can measure workpiece hole inner oil sump width tolerance simply, easily, measures efficient high, has guaranteed the crudy of workpiece hole inner oil sump.
Its technical scheme is such: groove width measurer in a kind of hole, it comprises the measurement regulator, be provided with through hole on described measurement regulator, be provided with movable measuring stick in described through hole, lever connects described measuring stick by elongated slot, described measuring stick two ends are provided with measuring head, and the measuring head diameter at described measuring stick two ends does not wait.
It is further characterized in that: described measurement regulator connecting handle.
In said structure of the present utility model, measure on regulator and be provided with through hole, be provided with movable measuring stick in through hole, lever connects measuring stick by elongated slot, the measuring stick two ends are provided with measuring head, the measuring head diameter at measuring stick two ends does not wait, and does not wait the side-to-side movement of measuring head by diameter, and whether measuring head can judge whether the width of hole inside groove satisfies tolerance in the patchhole inside groove.
Description of drawings
Fig. 1 is the main TV structure figure of groove width measurer in the utility model hole;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
see Fig. 1, groove width measurer in a kind of hole, it comprises measures regulator 1, measure regulator 1 connecting handle 7, measure on regulator 1 and be provided with through hole 2, be provided with movable measuring stick 3 in through hole 2, lever 4 connects measuring stick 3 by elongated slot 5, measuring stick 3 two ends are provided with measuring head 6-1, 6-2, the measuring head 6-1 at measuring stick two ends, the 6-2 diameter does not wait, measuring head 6-1, 6-2 processing is in normal margin tolerance, do not wait measuring head 6-1 by diameter, the side-to-side movement of 6-2, measuring head 6-1, whether 6-2 can judge whether the width of hole inside groove satisfies tolerance in the patchhole inside groove, if measuring head 6-1, 6-2 can the patchhole inside groove in, the margin tolerance that the hole inside groove is described is excessive, if measuring head 6-1, 6-2 all can not the patchhole inside groove in, the margin tolerance that the hole inside groove is described is too small, if measuring head 6-1, in 6-2 the large diameter measurement head can not the patchhole inside groove in, and in minor diameter measuring head energy patchhole inside groove, the margin tolerance of hole inside groove is normal.
Claims (2)
