Description
Technical field
The utility model relates to measure workpiece areas more particularly to a kind of high instrument for quick measuring of ruler.
Background technique
It is frequently necessary to use gear in mechanical equipment as a kind of driving parts, and it is wherein most commonly seen and ripe for people
The gear structure known is involute cylindrical gear.Gear needs high precision in production and processing, especially in ruler away from, tooth
High, space width and slot thickness etc., during Gear Production, need constantly to detect gear produced, but existing
Some measurement methods such as mostly use greatly to measure to gear items size at the measurement method than projective amplification, but the measurement method
Time and effort consuming, and it is easy to appear error, precision not can guarantee.
Patent Office of the People's Republic of China awards in a kind of utility model patent for disclosing device for measuring height of face tooth on the 15th of September in 2010
Power authorizes Publication No. CN201583222U comprising wedge block and pole, wherein the wedge block has a bottom flat
Face and a top bevel, and the angle between two faces is β；The end face of the angle β and face gear to be measured
The inclination angle of tooth is equal；The diameter of the pole when need to meet measurement pole at least part be stuck in the end face to be measured
It is in the tooth socket of tooth and tangent with two lateral tooth flanks.The utility model can actually efficiently measure height of face tooth, but still not
Tooth high measurement suitable for gear.
Utility model content
Current gear teeth high measurement is time-consuming and laborious, be easy to appear error, not can guarantee the problems such as measurement accuracy to solve, this
Utility model provides a kind of high instrument for quick measuring of ruler.It first has to realize the purpose that can carry out gear teeth high rapid survey,
And guarantee measurement accuracy on this basis, reduce operation difficulty, reduce human error.
To achieve the above object, the utility model uses following technical scheme.
A kind of high instrument for quick measuring of ruler, including base plate and the fixes sleeve for being fixed on base plate upper end, in fixes sleeve
It is plugged with perpendicular to base plate and elevating lever moving up and down, elevating lever upper end is plugged with a damping shaft for being parallel to base plate
It holds, damping bearing front end is fixedly connected with measuring rod, and damping bearing is plugged in the part in elevating lever and is fixedly connected with mark post, institute
It states elevating lever upper end cooperation mark post and is equipped with measuring flume, mark post is in measuring flume and can be fixed around damping bearing axis rotation
Grafting is parallel to the gear mounting rod of base plate on sleeve, and gear mounting rod is in the underface of damping bearing, and to fixation
Sleeve rear end extends to form handle.
Tooth height is that gear teeth the sum of is risen with height of teeth root, can also pass through measurement radius of addendum and root radius calculates two
Person's difference obtains.In the present apparatus, compared to measurement when measuring rod resists Gear Root circular portion to be measured perpendicular to base plate
The height that bar rises when resisting gear mounting rod perpendicular to base plate, along with the circular section radius of gear mounting rod is tooth root
Round radius, and when resisting Gear Root circular portion, as gear rotates, measuring rod is rotated around damping BEARING SHAFT with opposite direction
And damping bearing and mark post is driven to rotate, since there are motion-impeding frictional force between damping bearing and elevating lever, survey
Gauge rod stability of rotation and will not by gravity drop or rotation when by inertia force act on rise, be able to maintain high stabilization
Property therefore can ensure measurement accuracy, tooth top circular portion can not drive again measuring rod to rotate after gear turns an angle, read
The angle for taking mark post to rotate, can rapidly calculate radius of addendum according to trigonometric function, and then tooth height is calculated, and realize
Rapid survey tooth is high and measurement result is made to have the purpose of higher accuracy.
Preferably, the fixes sleeve side is equipped with fixing bolt, fixing bolt passes through fixes sleeve barrel and extends internally, Gu
Determine bolt bolt head after tightening to resist elevating lever, elevating lever is fixed.
Fixing bolt can be avoided the height when measuring rod is around damping BEARING SHAFT rotation and decline, and then cause under measurement accuracy
The problem of drop, occurs.
Preferably, the measurement groove edge is equipped with angle index, reading angular scale when measuring rod is perpendicular to base plate
It is 0 °.
Directly when measuring groove edge and being equipped with angle index and measuring rod perpendicular to base plate, reading angular scale makes for 0 °
The angle that can directly read mark post and measuring rod rotation is obtained, only needs to push away on mark post when facilitating calculating, and measuring rod being needed to be reset
To 0 ° of scale, it is simpler to reset operation.
Preferably, the elevating lever side is equipped with altitude scale, when measuring rod perpendicular to base plate and adjusts elevating lever
When measuring rod lower end being made to resist gear mounting rod, reading altitude scale is 0.
Similarly the setting of altitude scale and measuring rod are perpendicular to base plate and adjusting elevating lever makes measuring rod lower end resist tooth
Altitude scale is read when taking turns mounting rod can more easily read elevating lever lifting height, more convenient calculating for 0.And angle
Compared to taking remaining measurer to be read out, the numerical value of reading is more accurate, can avoid as far as possible for the setting of scale and altitude scale
The human error generated when using remaining gage measuring.
Preferably, the damping bearing, measuring rod and mark post three are mutually perpendicular to.
Three is mutually perpendicular to when then damping bearing is perpendicular to base plate mark post in parallel and base plate, read it is more convenient, it is whole
Body structure is more beautiful.
The beneficial effects of the utility model are:
1) the utility model clever structure can rapidly realize the high measurement of tooth；
2) easy to operate, it is not necessarily to special training, can quickly obtain tooth height by reading and substituting into formula calculating；
3) numerical value needed for each calculating can be directly read, and without remaining measurer, avoid human error.
