Description
Technical field
The utility model relates to survey inspection field of tool, more specifically, it relates to measure the outside circle of odd number gear shaft gear
With the vernier caliper of root diameter.
Background technique
It in the mapping experiment for making gear, needs to measure tip diameter, root diameter, determines that gear is each main with this
Parameter.Measurement tip diameter, root diameter are also required to when fabricating gear in the factory, whether detection gear part accords with
Close drawing requirement.When measuring even number gear, it can use vernier caliper and directly measure, but when measuring odd number gear,
Just opposite two teeth or two tooth sockets can not be found out, it is necessary to first survey some related amounts, then carry out necessary cumbersome
Conversion, be related to angle, trigonometric function etc..Due to measuring indirectly, error is big, precision is low, is such as surveyed using photoelectric instrument
Amount, cost is again higher, and school and some factories are difficult to realize.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of measurements to solve the above problems
The outside circle of odd number gear shaft gear and the vernier caliper of root diameter, are simply reequiped on common calliper, are led to
The tip diameter and root diameter of odd number gear shaft gear can be calculated after simple measurement twice, easy to operate accurate, cost
It is lower to be convenient for popularizing.
To achieve the above object, the utility model provides following technical solution:
The outside circle of odd number gear shaft gear and the vernier caliper of root diameter are measured, including main scale and is slidably connected at master
Auxiliary scale on ruler, main scale front end set up the first fixation measuring pawl and the second fixation measuring pawl separately up and down, and auxiliary scale front end sets up the separately up and down
One sliding measuring claw and the second sliding measuring claw, are fixed with measurement fixture block at the second fixation measuring pawl back side, measure fixture block
Medial surface is resisted against the medial surface that fixture block is measured on gear teeth tips periphery or on the root face of gullet base and the second fixed survey
Measuring jaw medial surface flushes.
It is that measure the measurement fixture block of outside circle be cuboid that the utility model, which is further improved technical solution,.Cuboid connects
Contacting surface is larger, is easy to jam on the tooth top periphery of the gear teeth when measuring outside circle, convenient for operation.
It is that measure the measurement fixture block of root circle be triangular prism or prismatoid that the utility model, which is further improved technical solution,.
Convenient for being stuck in tooth socket.
The further improved technology scheme of the utility model is, the prismatoid, triangular prism medial surface be rounded to cambered surface,
The top of cambered surface is flushed with the second fixation measuring pawl medial surface.The conflict cambered surface of measurement fixture block is bonded with root circle, measurement accuracy
It is more acurrate.
The further improved technology scheme of the utility model is the second fixation measuring pawl back side and the second sliding measuring claw back
Face flushes, and develops in measurement with gear face.Guarantee the accuracy measured size.
The utility model the utility model has the advantages that
The utility model slightly improves in existing vernier caliper structure, is additionally arranged measurement fixture block, and measurement outside circle is straight
When diameter jam the shaft gear gear teeth to be measured tooth crest, when measuring root diameter jam in the bottom of shaft gear tooth socket to be measured,
The second traverse measurement claw hook in auxiliary scale lives gear shaft relative on the distal end periphery of the tested gear teeth or tooth socket, measurement gained ruler
Very little to can be obtained again with gear shaft diameter of axle progress simple computation, easy to operate, data are accurate, and measurement card structure is simple, at low cost,
Convenient for universal.
Detailed description of the invention
Fig. 1 is the utility model backsight structure chart；
Fig. 2 is measurement tip diameter method schematic diagram.
Fig. 3 is measurement root diameter method schematic diagram.
Specific embodiment
As shown in Figure 1, the utility model includes main scale 1 and the auxiliary scale 2 that is slidably connected on main scale, above and below 1 front end of main scale
Set up the first fixation measuring pawl 11 and the second fixation measuring pawl 12 separately, 2 front end of auxiliary scale sets up the first sliding measuring claw 21 and the separately up and down
Two sliding measuring claws 22 are fixed with measurement fixture block 13 at the second fixation measuring pawl back side 121, and measurement fixture block medial surface 131 supports
Lean against the medial surface 131 that fixture block is measured on gear teeth tips periphery or on the root face of gullet base and the second fixation measuring pawl
Medial surface 122 flushes.
When measuring tip diameter, the medial surface for measuring fixture block hooks wheel tooth crest, the second traverse measurement pawl in auxiliary scale
Distal end periphery of the gear shaft relative to the tested gear teeth is hooked, in order to guarantee the accuracy measured size, second is fixed when measurement
The measuring claw back side and the second traverse measurement pawl back side flush, and all develop with gear face, as shown in Figure 2.A is measured size, then is surveyed
Gear diameter of axle size B is measured, formula D is passed throughTop=2A-B calculates tested addendum circle diameter of gear, is not required to by any tooling, two
Secondary measurement can be completed, and greatly improve measurement efficiency, guarantee measurement accuracy.The preferential cuboid of measurement fixture block 13 of outside circle
Shape is easy to jam on the tooth top periphery of tooth when measuring outside circle because rectangular contact level is larger, convenient for operation.
It when measuring root diameter, measures the preferred triangular prism of fixture block (or prismatoid), triangular prism measures fixture block insertion tooth slot
In, gullet base is hooked, the second traverse measurement claw hook in auxiliary scale lives distal end periphery of the gear shaft relative to tested tooth socket.For
Guarantee the accuracy measured size, the second fixation measuring pawl back side and the second traverse measurement pawl back side flush when measurement, all and
Gear face develops, as shown in Figure 3.A is measured size, then measures gear diameter of axle size B, passes through formula DRoot=2A-B, calculate by
Survey root diameter of gear.In order to measure fixture block fitting gullet base, it is described measurement fixture block prismatoid, triangular prism medial surface fall
At cambered surface, the top of cambered surface flushes circle with the second fixation measuring pawl medial surface.
