Description
Technical field
The utility model relates to mechanical field, particularly a kind of vernier caliper of the blade symmetry for detecting auger bit.
Background technology
In order to judge whether two blades of auger bit cause symmetry undesirable because of concentrated wear, need auger bit to deliver to instrument room, and needing could examine and determine through showing to protect bridge in dismounting, for skilled detection person, detecting and once needing about 20 minutes.But in the process that the processing site at auger bit and the blade to auger bit are whetted a knife, auger bit being delivered to instrument room, to carry out calibrating be unpractical, therefore cannot examine and determine auger bit in these cases.
The information being disclosed in this background technology part is only intended to increase the understanding to general background of the present utility model, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Utility model content
The purpose of this utility model is the vernier caliper providing a kind of blade symmetry for detecting auger bit, thus overcomes the defect cannot examined and determine auger bit in processing site and sharpening process in prior art.
For achieving the above object, the utility model provides a kind of vernier caliper of the blade symmetry for detecting auger bit, the medial surface of the lower measuring jaw of the main scale of vernier caliper is inclined-plane, and the medial surface of the lower measuring jaw of the vernier of vernier caliper is inclined-plane, the medial surface of the medial surface of the lower measuring jaw of main scale and the lower measuring jaw of vernier forms enlarging in downward direction.
Preferably, in technique scheme, the medial surface of the lower measuring jaw of main scale is identical relative to the oblique angle of main scale with the medial surface of the lower measuring jaw of vernier relative to main scale.
Preferably, in technique scheme, the medial surface of the medial surface of the lower measuring jaw of main scale and/or the lower measuring jaw of vernier is 121 ° relative to the oblique angle of main scale.
Compared with prior art, the utility model has following beneficial effect:
Vernier caliper simple light of the present utility model, be convenient for carrying processing site to detect auger bit with the scene of whetting a knife, and the length of the blade of auger bit can be measured rapidly, and the symmetry of the blade of auger bit is judged fast by contrast, can complete in 2 minutes, and accuracy is higher, substantially increase work efficiency, the asymmetric bias that causes of the blade of auger bit can be avoided simultaneously and produce waste product.
Accompanying drawing explanation
Fig. 1 is the structural drawing of the vernier caliper according to the blade symmetry for detecting auger bit of the present utility model.
Main Reference Numerals illustrates:
1-vernier caliper, the lower measuring jaw of 11-main scale, the lower measuring jaw of 12-vernier, 2-auger bit, 21-first blade, 22-second blade, 23-seamed edge.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole instructions and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or ingredient, and do not get rid of other element or other ingredient.
As shown in Figure 1, substantially identical with the structure of common vernier caliper according to the structure of the vernier caliper 1 of the blade symmetry for detecting auger bit of the utility model embodiment, comprise main scale and vernier.The medial surface (near testee) of the lower measuring jaw 11 of main scale is inclined-plane, the medial surface (near testee) of the lower measuring jaw 12 of vernier is inclined-plane simultaneously, and the medial surface of the medial surface of the lower measuring jaw 11 of main scale and the lower measuring jaw 12 of vernier defines enlarging in downward direction.Preferably, the medial surface of the lower measuring jaw 11 of main scale is identical relative to the oblique angle of main scale with the medial surface of the lower measuring jaw 12 of vernier.
As shown in Figure 1, auger bit 2 comprises the first blade 21, second blade 22 and seamed edge 23.
When using above-mentioned vernier caliper to detect the blade symmetry of auger bit, respectively the length of two blades of auger bit is detected, then contrast the length of two blades, judge whether equal.If the length of two blades is equal, then the symmetry of auger bit meets the requirements; Otherwise, undesirable.
As shown in Figure 1, to detect the first blade 21, the first blade 21 is resisted against on the bottom surface of main scale, makes the seamed edge of auger bit 2 near the inclined-plane of the lower measuring jaw of main scale; Then moving cursor, makes vernier be resisted against on the point of a knife of auger bit 2; Finally, the reading of vernier caliper is read.Identical method is adopted to measure the length of the second blade 22.
Due to standard auger bit two blades between angle be 118 °, the angle of each blade and axial line (i.e. seamed edge) is 121 °, therefore, preferably, the medial surface of the medial surface of the lower measuring jaw 11 of main scale and/or the lower measuring jaw 12 of described vernier is 121 ° relative to the oblique angle of main scale, collides and be damaged with the inclined-plane of the lower measuring jaw preventing another blade and vernier when measuring one of them blade.
Vernier caliper simple light of the present utility model, be convenient for carrying processing site to detect auger bit with the scene of whetting a knife, and the length of the blade of auger bit can be measured rapidly, and the symmetry of the blade of auger bit is judged fast by contrast, can complete in 2 minutes, and accuracy is higher, substantially increase work efficiency, the asymmetric bias that causes of the blade of auger bit can be avoided simultaneously and produce waste product.
The aforementioned description to concrete exemplary of the present utility model is to illustrate and the object of illustration.These descriptions not want the utility model to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present utility model and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present utility model and various different selection and change.Scope of the present utility model is intended to limited by claims and equivalents thereof.
