Abstract
The invention discloses a belt pulley coplanar detection device and method. The belt pulley coplanar detection device comprises: two bases which are detachably connected to an end face of a belt pulley; two scale devices which are connected to the bases correspondingly; and a laser transmitter which is detachably mounted on one of the bases and can rotate relative to the base. Because the laser transmitter is detachably connected with the base and can rotate relative to the base, the detection freedom degree is enabled to be larger and the detection is more flexible. At the same time, because the base is detachably connected with the belt pulley, the entire detection mechanism is enabled to be easy to carry and convenient in disassembly and assembly, and has the quite high detection precision.

Detailed description of the invention
Below in conjunction with the accompanying drawings, the detailed description of the invention of the present invention is described in detail, it is to be understood that this
The protection domain of invention is not limited by detailed description of the invention.
As it is shown in figure 1, which show the pedestal 1 of the band guide hole 11 according to the present invention.Pedestal 1 is detachable
Be arranged on the end face of belt pulley.In the present embodiment, pedestal 1 is made up or in it of magnetic material
Magnet is contained in portion, is therefore adsorbed the end face at belt pulley by magnetic force.Certainly it is not limited thereto, this
Skilled person is readily apparent that, in other dismountable mode, pedestal is assembled to belt pulley
On.
In this specific embodiment, pedestal 1 includes protuberance 12, and this protuberance 12 is inserted into pedestal 1
In and be fixed on pedestal 1 by bolt 13.Guide hole 11 is arranged on the free end of protuberance 12, and this is led
Hole 11 is through hole, is circular in the present embodiment, but is not limited thereto.
See Fig. 2, which show the generating laser 2 according to the present invention and be arranged on the end face of pedestal 1.
In this embodiment, generating laser 2 is removably pacified by the rotary shaft 21 with certain damping
It is contained on pedestal 1, and can rotate relative to pedestal 1 under the drive of rotary shaft 21.Specifically,
Such as in figure 2 it is shown, be provided with mounting seat in the end of rotary shaft 21, generating laser passes through locking screw
Following closely 22 and be fixed in mounting seat, after assembling, this generating laser 2 is the most irremovable, but permissible
The depth of parallelism with base mounting surface is adjusted by lock screw 22.
In practical operation, generating laser 2 is guided to be positioned at the side of belt pulley, is easily subject to weight
The impact of power and rotate and then affect measuring accuracy.In the present invention, due to rotary shaft 21 and pedestal 1 it
Between with certain damping, the most only this generating laser 2 just meeting in the case of operator applies external force
Rotate, this generating laser 2 will not rotate because of gravity factor, and need not dish move belt pulley can be complete
Become to measure, hence in so that measure easier and efficient.
See Fig. 3, which show the graduation apparatus 3 according to the present invention.In the middle of this detailed description of the invention,
Graduation apparatus 3 includes scale 31 and race probe 32.One end of described scale 31 has scale, another
Hold and fix with race probe 32.This scale 31 is cylindrical in the present embodiment, its diameter and base
The diameter of the guide hole 11 of seat 1 matches and closely cooperates with this guide hole, and scale 31 can be along guide hole 11 axle
To movement.One end of scale 31 is provided with scale, and its other end fixes with race probe 32.
With reference to Fig. 3 as shown in Figure 4, due to the V-shaped groove that the pulley groove of belt pulley A is symmetry, therefore
Under the effect of external force, the free end of race probe 32 can automatic centering in V-shaped groove 4, thus real
Existing coplanar detection.
Below in conjunction with Fig. 5 and Fig. 6, the detection method that the belt pulley according to the present invention is coplanar is situated between in detail
Continue.
First, the pedestal 1 with generating laser 2 is adsorbed onto on the end face of belt pulley A, then exists
Guide hole inserts the race probe of band scale, rotates and move axially along guide hole the race probe 32 of band scale,
The race probe 32 making band scale is stuck on the corresponding V-shaped groove of belt pulley A.
Then the pedestal 1 ' with same size is adsorbed onto on the end face of belt pulley B, its absorption position with
The pedestal 1 absorption position relative to belt pulley A is the most corresponding.It is not provided with generating laser on this pedestal 1 '
2.Then, and in the guide hole of pedestal 1 ' insert band scale race probe 32 ', the scale of this pedestal 1 '
The scale arranged in the size popped one's head in race and pedestal 1 and the consistent size of race probe.Rotate and edge
Guide hole moves axially the race probe 32 ' of band scale, makes the race probe 32 ' of band scale be stuck in belt pulley
On the corresponding V-shaped groove of B.
It follows that rotary laser emitter 2, it is respectively radiated to the scale on pedestal 1 and pedestal 1 ', respectively
Reading scale reading D and D ' thereon, the difference of comparative reading value i.e. can get belt pulley A and belt pulley
B pulley groove is the most coplanar and calculates its difference.
It is connected with pedestal by dismountable mode due to laser beam emitting device and can revolve relative to pedestal
Turn, hence in so that detection degree of freedom is bigger, detect the most flexible.Simultaneously as pedestal is by detachable
Mode be connected with belt pulley so that whole testing agency is convenient for carrying, easy accessibility, and has
The highest accuracy of detection.
The specific embodiment being only the present invention disclosed above, but, the present invention is not limited to this, appoints
What what those skilled in the art can think change all should fall into protection scope of the present invention.
