Abstract
The invention discloses a tool for confirming a central line in a workpiece slot. The tool comprises a cylindrical hand-holding part (1) and a working part, wherein the cylindrical hand-holding part and the working part are integrated; the whole working part is formed by inwardly retracting the diameter of the cylindrical hand-holding part; and upper and lower rectangular working planes (2) axially in parallel with the cylindrical hand-holding part are extended outwardly in a retracting position; and a sharp bump (4) is arranged in a center of an end plane (3) of the working part. The tool for confirming the central line in the workpiece slot has the following beneficial effects that the working part of the tool is arranged in the slot; two opposite angles of the end plane of the working part of the tool are contacted with a slot wall and the central line can be drawn by the sharp bump on the end plane; and therefore, the tool is convenient and efficient to use.
Description
Technical field
The present invention relates to field of machining, particularly relate to a kind of instrument determining center line in workpiece slot.
Background technology
At industrial machinery manufacture field, often need to mark various boost line in the groove to workpiece as center line etc., for perforating afterwards, standby boring and tapping are prepared, and the existing instrument of center line such as the gage that will mark in workpiece slot is difficult to accomplish owing to being blocked by notch, measurement result is inaccurate.
Summary of the invention
The technical problem to be solved in the present invention is that the instrument of center line in existing measuring workpieces groove is measured inaccurate, provides a kind of instrument can determining center line in workpiece slot for this reason.
Technical scheme of the present invention is: a kind of instrument determining center line in workpiece slot, it comprises integrated cylindrical Handheld Division and operate portions, described operate portions entirety be by cylindrical Handheld Division diametrically in shrink and form and extend outward upper and lower two rectangle working faces parallel with the axis of cylindrical Handheld Division in contraction place, the end face center of operate portions is provided with sharp protrusion.
The invention has the beneficial effects as follows and the operate portions of instrument is placed in groove, make two diagonal angle contact cell walls of the operate portions end face of instrument that the sharp protrusion on end face just can be utilized to mark center line, convenient to use.
Accompanying drawing explanation
Fig. 1 is that the present invention uses schematic diagram;
In figure, 1, cylindrical Handheld Division, 2, rectangle working face, 3, the end face of operate portions, 4, sharp protrusion.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, the present invention includes integrated cylindrical Handheld Division 1 and operate portions, described operate portions entirety be by cylindrical Handheld Division diametrically in shrink and form and extend outward upper and lower two rectangle working faces 2 parallel with the axis of cylindrical Handheld Division in contraction place, end face 3 center of operate portions is provided with sharp protrusion 4.
In the present invention, the end face catercorner length of operate portions is longer than workpiece groove width, and the groove insied width caing be compared to workpiece most grows 1.5mm.
The present invention uses like this: when needs are in the groove of workpiece during standardized bar 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 center contacts with groove inner bottom surface, along Move tool in groove, the center line of groove just can be marked.
Claims (1)
1. determine the instrument of center line in workpiece slot for one kind, it is characterized in that it comprises integrated cylindrical Handheld Division (1) and operate portions, described operate portions entirety be by cylindrical Handheld Division diametrically in shrink and form and extend outward upper and lower two rectangle working faces (2) parallel with the axis of cylindrical Handheld Division in contraction place, end face (3) center of operate portions is provided with sharp protrusion (4), and end face catercorner length grows 1.5mm than the groove insied width of workpiece.
