Abstract
This utility model relates to a kind of detection instrument, is specifically related to a kind of for bit central special detection tool.Including drill bit to be detected, described detection instrument is made up of cylindrical gauge block and datum line, described gauge block is spliced by two pieces of identical semi-cylindrical gauge blocks one and gauge block two, the internal diameter of described gauge block matches with the external diameter of the drillstock of drill bit to be detected, described gauge block can be sheathed on drill bit to be detected just, described gauge block is made up of metal material, and described datum line is the copper wire of 0.1mm or tungsten filament or fine rule.This utility model simple in construction, easy to use, practical, bit central accuracy in detection is high, relatively prior art, it is possible to be prevented effectively from the adverse consequencess such as the Drill Crack caused because of range estimation deviation, punching deflection.
Description
Technical field
This utility model relates to a kind of detection instrument, is specifically related to a kind of detection instrument for bit central.
Background technology
During machinery industry produces at present, great majority use manual crusher drill, are determined the center of drill bit by range estimation.Yet with the poor accuracy of range estimation, easily cause hard alloy, high-speed steel drill Drill Crack phenomenon, breaking for several times in even a day when using, drastically increase production cost；It is easily caused the adverse consequences such as punching deviation, punching part quality decline, even part rejection simultaneously.
Utility model content
For the deficiencies in the prior art, this utility model provides a kind of bit central special detection tool.
Technical solutions of the utility model are as follows:
A kind of bit central special detection tool, including drill bit to be detected, described detection instrument is made up of cylindrical gauge block and datum line, described gauge block is spliced by two pieces of identical semi-cylindrical gauge blocks one and gauge block two, the internal diameter of described gauge block matches with the external diameter of the drillstock of drill bit to be detected, described gauge block can be sheathed on drill bit to be detected just, and described gauge block is made up of metal material, and described datum line is the copper wire of 0.1mm or tungsten filament or fine rule.
The beneficial effects of the utility model are: simple in construction, easy to use, practical, and bit central accuracy in detection is high, relatively prior art, it is possible to be prevented effectively from the adverse consequencess such as the Drill Crack caused because of range estimation deviation, punching deflection.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Wherein: 1, gauge block one；2, datum line；3, gauge block two.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
Refering to Fig. 1, a kind of bit central special detection tool, including drill bit to be detected, described detection instrument is made up of cylindrical gauge block and datum line 2, described gauge block is spliced by two pieces of identical semi-cylindrical gauge blocks 1 and gauge block 23, and the internal diameter of described gauge block matches with the external diameter of the drillstock of drill bit to be detected, and described gauge block can be sheathed on drill bit to be detected just, described gauge block is made up of metal material, and described datum line 2 is the copper wire of 0.1mm or tungsten filament or fine rule.
During use, the drill bit to be detected of manual milled is inserted in gauge block, and datum line strain clamp is held in gauge block 1 and the connecting portion at gauge block 23 two ends, whether observe bit central through datum line 2, the most again by bit 90 degree, whether again observe bit central through this datum line 2, if all passing through this datum line 2 for twice, then explanation bit central heart position wherein, simple to operate, accuracy in detection is high, relatively prior art, the adverse consequencess such as the Drill Crack caused because of range estimation deviation, punching deflection can be prevented effectively from.
Above-mentioned drawings and Examples are merely to illustrate this utility model, suitably change that it is done by any art those of ordinary skill or modify, or use other flower pattern instead and make this technical change, the most all should be regarded as without departing from this utility model patent category.
