Description
Technical field
The utility model relates to technical field of bearings, especially a kind of bearing circular runout detection device.
Background technique
Bearing is all to be installed with internal-and external diameter, therefore bearing internal external diameter size must be strictly controlled in the tolerance wanted when in use
In range, it otherwise just will appear and do not install or the excessive problem that can not be fixed in gap, therefore each bearing producer requires
The internal-and external diameter of bearing is accurately detected, the bearing circular runout due to caused by radial beat eccentricity deviation can be to bearing rotary
Precision impacts, and is in the prior art generally fixed bearing using a slewing equipment to the circular runout detection of bearing, so
Keep bearing concentric with slewing equipment in the heart afterwards, then plays table and detect radial jump degree, but the process that bearing is concentric with slewing equipment
It is complex, it is completely inaccurate if the jump degree that decentraction detected.
Utility model content
The problem of causing bearing rotation precision to reduce because of circular runout purpose of the utility model is to solve bearing, and
There is provided one kind can be by bearing and slewing equipment quickly to the bearing circular runout detection device of the heart.
The technical solution adopted in the utility model are as follows: a kind of bearing circular runout detection device, including can horizontally rotate
Bottom plate, helicla flute is provided on bottom plate, bottom plate is provided centrally with rotatable column, multiple cross bars, cross bar are evenly equipped with outside column
On be cased with the sliding block that can be slided on cross bar, protrusion insertion helicla flute is provided with below sliding block and is slided along helicla flute, sliding block
On be provided with boss for clamping bearing, all boss are used to clamp the stationary plane of bearing to rotation axis apart from identical, and also
Including the bracket for fixation measuring device.
Further, the boss is detachably connected with sliding block, make boss for clamp the stationary plane of bearing inwardly or
Outwardly.
Further, the bracket includes column and the cross bar that can go up and down on column, and being provided on cross bar being capable of edge
The mobile fixture for fixation measuring device of cross bar.
Further, the bottom plate by motor or can be manually rotated.
Further, the measuring device is amesdial.
The utility model has the beneficial effects that the detection device of the utility model being capable of quick fixing axle using chuck principle
It holds, concentricity is high, guarantees the accuracy of measurement circular runout, easy to use, the simple price of structure is low.
Detailed description of the invention
Fig. 1 is the main view of the utility model；
Fig. 2 is the top view of the utility model.
In figure: 1- bottom plate, 2- helicla flute, 3- column, 4- cross bar, 5- sliding block, 6- protrusion, 7- boss, 8- bracket, 801- are vertical
Column, 802- cross bar, 803- fixture, 9- measuring device.
Specific embodiment
The utility model is described further with reference to the accompanying drawing.
As shown in Figure 1, a kind of bearing circular runout detection device, including the bottom plate 1 that can be horizontally rotated, bottom plate 1 passes through
Motor can be manually rotated, and helicla flute 2 is provided on bottom plate 1, and bottom plate 1 is provided centrally with rotatable column 3, is evenly distributed with outside column 3
There are multiple cross bars 4, the sliding block 5 that can be slided on cross bar 4 is cased on cross bar 4, protrusion 6 is provided with below sliding block 5 and is inserted into spiral
Slot 2 is simultaneously slided along helicla flute 2, the boss 7 for clamping bearing is provided on sliding block 5, all boss 7 are for clamping consolidating for bearing
Face is determined to rotation axis apart from identical, and boss 7 is detachably connected with sliding block 5, makes boss 7 for clamping the stationary plane of bearing inwardly
Or outwardly, stationary plane inwardly when clamp bearing outer ring, can measure bearing inner race circular runout, it is fixed to clamp bearing when facing outwardly
Inner ring can measure bearing outer ring circular runout, further include the bracket 8 for fixation measuring device, and bracket 8 includes 801 He of column
The cross bar 802 that can be gone up and down on column 801 is provided with filling for fixation measuring of can moving along cross bar 802 on cross bar 802
9 fixture 803 is set, measuring device 9 is amesdial, naturally it is also possible to be other measuring devices.
The application method of the utility model detection device, it is first by taking the inner peripheral surface radial direction jump degree for detecting bearing inner race as an example
First the stationary plane that boss 7 is used to clamp bearing is fixed on sliding block 5 inwardly, rotates clockwise column 1, makes cross bar 4 with cunning
Block rotation, synchronizes all sliding blocks 5 to slide in and out, bearing is then placed on cunning since the protrusion 5 of sliding block is slided in helicla flute 2
On block, another mistake hour hands Rotary cloumn 1, the synchronous slid inwards of all sliding blocks 5 make boss 7 clamp bearing outer ring, clamp rear bearing with
Bottom plate 1 with one heart, then the height of adjusting bracket 8 and gos deep into length, is that the gauge outfit of amesdial is scheduled on the inner peripheral surface of bearing inner race
On, rotary bottom plate 1 can detect radial jump degree.Easy to use, detection is quick.
When similarly detecting the radial jump of bearing outer circumference surface and spending, it is only necessary to which boss 7 is used to clamp the stationary plane court of bearing
It is fixed on sliding block 5, is same as above with step outside.
In other embodiments, bracket 8 can also use sliding rail, the other embodiments fixation measuring such as flexible support dress
It sets.
Specific embodiment is the further explanation to the utility model rather than limits, and is come to those of ordinary skill in the art
It says and further transformation is done to structure in the case where not departing from the utility model in essence content, and all these transformation all should belong to
The protection scope of the appended claims for the utility model.
