Description
Technical field
The utility model belongs to the measuring instrument field of circularity.
Background technology
Axle is support rotary part and turned round therewith to transmit motion, moment of torsion or the conventional machinery part of moment of flexure.One
As for, major axis refers to axle of the length more than 2 meters.And the length of axle is longer, then it more easily shifts in quick rotation
Vibration, stability are then also poorer.
Axle is intended to carry out the measurement of circularity after machining.The roundness measuring device of existing axle generally includes base
And dial gauge, shaft member to be measured is rotatably arranged on base, then dial gauge and shaft member to be measured offseted, turning of work piece
One week, and the fluctuation of percentage list index is observed, full-scale reading Mmax and least count Mmin difference are taken, then can calculate this
The coaxiality error in section.However, in the actual measurement process of major axis, because velocity of rotation is too fast, bearing can be caused inclined
Move, cause the deviation of roundness measurement to increase.In order to avoid the phenomenon, then the velocity of rotation for slowing down major axis that can be tried one's best, and big
When the detection of batch, then the measurement efficiency of major axis can be caused too low.
Utility model content
The purpose of this utility model is to provide a kind of major axis roundness measuring device, to increase the measurement efficiency of major axis.
In order to achieve the above object, base case of the present utility model provides a kind of major axis roundness measuring device, including bottom
Seat and dial gauge, the base be provided with for shaft member to be measured rotate bearing, in addition to slide rail, warning lamp and for control warn
The switch of lamp, the slide rail are arranged on base, and the warning lamp is fixed on base, and the switch electrically connects with warning lamp,
And switch is slidably arranged on slide rail.
The principle of this base case is：First, major axis is arranged on base；Then dial gauge and switch are adjusted
Position, the surface of dial gauge and major axis is offseted, and have the decrement of 1~2 circle；Meanwhile switch is set to be located at the lower section of major axis.
The specific distance of switch and major axis is then adjusted according to actual acceptable error.Afterwards, can be with relatively quick speed
To rotate major axis, ensure as far as possible at the uniform velocity.If indicator lamp is non-lit up during this, illustrate that the numerical value that dial gauge measures is more accurate.And
If indicator lamp is lighted during this, specification error is bigger to be remeasured, it is necessary to slow down speed.
The beneficial effect of this base case is：For traditional measuring instrument, this programme when measuring major axis,
The speed that can more accelerate measures, and the situation for occurring excessive velocities once in a while and causing indicator lamp to be lighted even occurs, then
It is secondary regulate the speed after the speed that measures still be faster than traditional instrument, be effectively increased the detection efficiency of major axis.Meanwhile
Because speed is relative to before faster, then comparatively, skew during measurement can be larger, therefore, passes through the major axis of the test
Precision it is more preferable.
Scheme two：Scheme is preferred based on this, and the first magnet is hinged with the side wall on the switch, the slide rail
Bottom is provided with second magnet corresponding with the first magnet, when first magnet rotors are to bottom, the first magnet and
Two magnet mutually attract.Because switch is slidably arranged on slide rail, once contacted with major axis, easily it is moved.First
The setting of magnet and the second magnet, together with by the first magnet rotors to bottom, mutually attracting with the second magnet, then it will can open
Close and fix.It is easy to operate again the first magnet rotors to top when needing moving switch.
Scheme three：Scheme is preferred based on this, and first magnet and the second magnet are permanent magnet.Relative to common
Magnet, the life-span of the first magnet and the second magnet made of permanent magnet are higher.
Scheme four：Scheme is preferred based on this, and the dial gauge is digital display centimeter.Digital display centimeter is easier to observe
Measurement result, it is easy to operate.
Scheme five：Scheme is preferred based on this, and the warning lamp is red LED lamp.Red LED lamp when lighting,
More obvious, warning function is stronger.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment major axis roundness measuring device.
Fig. 2 is Fig. 1 side view.
Fig. 3 is the structural representation of the first magnet in Fig. 1.
Embodiment
The utility model is described in further detail below by embodiment：
Reference in Figure of description includes：Base 10, dial gauge 20, major axis 30, warning lamp 40, switch 50, peace
Fill seat 60, slide rail 70, the second magnet 80, the first magnet 90.
As shown in Figure 1 and Figure 2, a kind of major axis roundness measuring device, including base 10, dial gauge 20, slide rail 70, warning lamp
40 and for controlling the switch 50 of warning lamp 40.The quantity of base 10 is two, is equipped with each base 10 for shaft member to be measured
The bearing of rotation.Dial gauge 20 uses digital display centimeter 20, and measurement more facilitates.Slide rail 70 is arranged between two bases 10,
And positioned at the lower section of major axis 30.
Warning lamp 40 is adopted as red LED lamp, and red LED lamp is more obvious when lighting, and warning function is stronger.
Led lamps are arranged on base 10, and are connected by electric wire with switch 50.Switch 50 is provided with mounting seat 60, is set in mounting seat 60
There are the structure with the phase clamping of slide rail 70, specially prior art, just do not repeat excessively.
As shown in figure 3, being also hinged the first magnet 90 in the side wall of mounting seat 60, the first magnet 90 is plate-like.Meanwhile
The second magnet 80 to match with the first magnet 90 is further fixed in slide rail 70, when the first magnet 90 is turned into bottom,
Apart from very near, its magnetic force from each other can be used for fixed switch 50 for first magnet 90 and the second magnet 80.In order to more preferable
Increase the service life of this product, also the first magnet 90 and the second magnet 80 are made of permanent magnet material.
During concrete operations, first, major axis 30 is arranged on base 10；Then the position of dial gauge 20 and switch 50 is adjusted
Put, the surface of dial gauge 20 and major axis 30 is offseted, and have the decrement of 1~2 circle；Meanwhile switch 50 is set to be located at major axis 30
Lower section.The specific distance of switch 50 and major axis 30 is then adjusted according to actual acceptable error.Afterwards, can be with relatively fast
The speed of speed rotates major axis 30, ensures as far as possible at the uniform velocity.If indicator lamp is non-lit up during this, illustrate the number that dial gauge 20 measures
Value is more accurate.And if indicator lamp is lighted during this, specification error is bigger to be remeasured, it is necessary to slow down speed.
For traditional measuring instrument, this programme when measuring major axis 30, surveyed by the speed that can more accelerate
, even there is the situation for occurring excessive velocities once in a while and causing indicator lamp to be lighted, is measured after regulating the speed again in amount
Speed is still faster than traditional instrument, is effectively increased the detection efficiency of major axis 30.Simultaneously as speed is relative to before more
It hurry up, then comparatively, skew during measurement can be larger, and therefore, the precision by the major axis 30 of the test is more preferable.
Above-described is only embodiment of the present utility model, and the general knowledge such as known concrete structure and characteristic is herein in scheme
Do not describe excessively.It should be pointed out that for those skilled in the art, the premise of the utility model structure is not being departed from
Under, several modifications and improvements can also be made, these should also be considered as the scope of protection of the utility model, and these are all without influence
The effect and practical applicability that the utility model is implemented.This application claims protection domain should be with the content of its claim
It is defined, the record such as embodiment in specification can be used for the content for explaining claim.
