Description
Technical field
The utility model relates to measure workpiece areas more particularly to a kind of adjustable gear depth gauge.
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 be easy to appear error, precision not can guarantee, and while carrying out tooth high measurement to the gear of different size needs pair
Instrument is adjusted, and adjustment process is very complicated.
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 measurement accuracy to solve, and to difference
The problems such as gear of specification carries out when tooth high measurement needing that instrument is adjusted, and adjustment process is very complicated, the utility model
Provide a kind of adjustable gear depth gauge.First have to realize can gear teeth height to different size carry out the mesh of 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 adjustable gear depth gauge, including base plate and the fixes sleeve for being fixed on base plate upper end, fixes sleeve
It is inside plugged with perpendicular to base plate and elevating lever moving up and down, elevating lever upper end is plugged with a damping for being parallel to base plate
Bearing, damping bearing front end are fixedly connected with measuring rod, and damping bearing is plugged in the part in elevating lever and is fixedly connected with mark post,
The elevating lever upper end cooperation mark post is equipped with measuring flume, and mark post is in measuring flume and can rotate around damping bearing axis, Gu
Determine the interior mounting rod that grafting on sleeve is parallel to base plate, interior mounting rod is in the underface of damping bearing, outside interior mounting rod
It is arranged with installation rod sleeve, interior mounting rod extends to form handle to fixes sleeve rear end.
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 installation rod sleeve perpendicular to base plate, along with the radius of the circular section outer circle of installation rod sleeve is
For the radius of root circle, and when resisting Gear Root circular portion, as gear rotates, measuring rod is around damping BEARING SHAFT with negative side
To rotating and drive damping bearing and mark post to rotate, due between damping bearing and elevating lever there are motion-impeding frictional force,
Therefore measuring rod stability of rotation and will not by gravity drop or rotation when by inertia force act on rise, be able to maintain high
Stability therefore can ensure measurement accuracy, after gear turns an angle tooth top circular portion can not drive again measuring rod turn
It is dynamic, the angle of mark post rotation is read, radius of addendum can be rapidly calculated according to trigonometric function, and then tooth is calculated
Height realizes the purpose that rapid survey tooth is high and measurement result is made to have higher accuracy.Rod sleeve and interior mounting rod are installed
It is arranged back axis coincidence.Installation rod sleeve can carry out selection use according to gear set specifications, can prepare in advance various outer diameter specification,
Internal diameter is equal to the installation rod sleeve of interior mounting rod outer diameter, to carry out quick-replaceable in the gear measurement to different size.
Preferably, the installation rod sleeve and interior mounting rod are equipped with several screw holes being mutually adapted, rod sleeve is installed
It is fixed with interior mounting rod by installing bolt in compatible screw hole.
It is fixed by screw and bolt cooperation, the relative rotation for being able to maintain installation rod sleeve and interior mounting rod is stablized
Property, so in rotate gear keep gear stabilization, improve measuring accuracy.
Preferably, the screw hole is through-hole, the vertical interior mounting rod axle center in screw hole axle center, adjacent screw hole is in transverse and longitudinal friendship
It is wrong.
The staggered bolt of transverse and longitudinal and stability when screw hole cooperation backgear rotation are higher.
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, facilitates calculating, and measuring rod is needed to be reset to perpendicular to base plate
When only need for mark post to be pushed into 0 ° of scale, reset operation it is simpler.
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 installation rod sleeve, 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 peace
Altitude scale is read when filling rod sleeve 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 be realized rapidly and carry out tooth high measurement to the gear of different size；
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.
