Abstract
The utility model discloses a tool for fixing a center line in a work piece groove, which comprises a cylindrical handheld part (1) and an operating part which are integrally formed. The operating part is formed by inward contracting the diameter of the cylindrical handheld part; two rectangular operating surfaces (2) which are parallel with the axial direction of the cylindrical handheld part extend out from the contracting position; and a sharp bulge (4) is formed at the center of the end surface (3) of the operating part. The tool has the beneficial effects that the operating part of the tool is arranged in the groove, so that two opposite angles of the end surface of the operating part contact with the wall of the groove, then the sharp bulge on the end surface can be utilized to mark a center line, and the tool is convenient and efficient to use.
Description
Technical field
The utility model relates to field of machining, relates in particular to the instrument of center line in a kind of definite workpiece groove.
Background technology
At the industrial machinery manufacture field, often need to mark various boost lines such as center line etc. in the groove to workpiece, for perforating afterwards, standby boring and tapping are prepared, and the center line that will mark in the workpiece groove is difficult to accomplish owing to being blocked by notch with existing instrument such as gage, and measurement result is inaccurate.
The utility model content
The technical problems to be solved in the utility model is that the instrument measurement of center line in existing measuring workpieces groove is inaccurate, and a kind of instrument that can determine center line in the workpiece groove is provided for this reason.
The technical solution of the utility model is: the instrument of center line in a kind of definite workpiece groove, it comprises integrated cylindrical Handheld Division and operate portions, described operate portions integral body is inwardly to shrink by cylindrical Handheld Division diameter the rectangle working face that consists of and extend outward two of up and down and the axially parallel of cylindrical Handheld Division in the contraction place, and the end face center of operate portions is provided with sharp protrusion.
The beneficial effects of the utility model are that the operate portions with instrument is placed in groove, make two diagonal angles contact cell walls of the operate portions end face of instrument just can utilize the sharp protrusion on end face to mark center line, and are convenient to use.
Description of drawings
Fig. 1 is that the utility model uses schematic diagram;
In figure, 1, cylindrical Handheld Division, 2, the rectangle working face, 3, the end face of operate portions, 4, sharp protrusion.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, the utility model comprises integrated cylindrical Handheld Division 1 and operate portions, described operate portions integral body is inwardly to shrink by cylindrical Handheld Division diameter the rectangle working face 2 that consists of and extend outward two of up and down and the axially parallel of cylindrical Handheld Division in the contraction place, and end face 3 centers of operate portions are provided with sharp protrusion 4.
In the utility model, the end face catercorner length of operate portions is longer than the workpiece groove width, and the groove insied width that cans be compared to workpiece most grows 1.5mm.
The utility model is to use like this: in need to the groove at workpiece during standardized center line, the end face 3 of the operate portions of instrument is inserted in groove, make two diagonal angle contact cell walls of the end face 3 of operate portions, the sharp protrusion 4 at operate portions end face 3 centers contacts with the groove inner bottom surface, along Move tool in groove, just can mark the center line of groove.
Claims (1)
