A kind of can Multi-angle free rotate cylindrical shape appearance detection device support
Technical field
The present invention relates to the appearance detection device field of part, can Multi-angle free in particular to one
The cylindrical shape appearance detection device support rotated.
Background technology
Automobile engine cylinder is executive component important in parts.Owing to producing equipment or operating technology level
Etc. reason, often there is visual flaw in the cylinder block during reality produces.Therefore, it is necessary to go out in cylinder block
The outward appearance detection being correlated with is carried out before factory.The scope of outward appearance detection specifically includes that all planes of cylinder body should not have
Significantly protrusion, depression, cut and defect.Wherein, the deformation formed due to the effect of material internal stress
Depression is common flaw.
Following function at least should be had: be freely rotatable for detecting the appearance detection device of cylinder surface defect.
When appearance detection device rotates freely, appearance detection device can keep cylinder body to be fixed on appearance detection device
In, and then enable examiner to check all planes of cylinder body in all directions.But, how to make visual examination
Equipment can rotate freely, and is but a technical problem being worth research.
Summary of the invention
Technical problem solved by the invention: design a kind of support for carrying appearance detection device, this
Frame can make appearance detection device realize Multi-angle free rotation.
The present invention provides following technical scheme: a kind of can the cylindrical shape appearance detection device that rotates of Multi-angle free
Support, the bearing unit including pallet, being arranged on pallet, is arranged on pallet by axle and bearing unit
The movable machine frame of side, described movable machine frame is used for laying cylindrical shape appearance detection device, described movable machine frame with
Cylindrical shape appearance detection device phase-contact surface is the contact site in circular shape, and described contact site two ends are provided with axle
Hold;Bearing follower is installed in the middle part of described contact site;
Bearing unit fitted shaft on pallet is freely rotatable movable machine frame, and movable machine frame drives and lays thereon
Cylindrical shape appearance detection device, thus realize rotating freely of cylindrical shape appearance detection device, this is first
Rotating freely of angle;Technical scheme as described below can realize rotating freely of the second angle: cylindrical shape outward appearance
Inspection equipment is placed on movable machine frame by the contact site of circular shape, and the bearing at contact site two ends can make circle
Tubular appearance detection device rotates freely around the central axis of himself.
By technique scheme, cylindrical shape appearance detection device realizes Multi-angle free and rotates, for examiner
All planes of comprehensive inspection cylinder body provide technical conditions, and therefore, the technical program has useful skill
Art effect.
As a further improvement on the present invention, described movable machine frame base plate is provided with axle bed.
As a further improvement on the present invention, described pallet being also equipped with castor, the quantity of described castor is
Four, it is distributed in the corner of pallet.

Detailed description of the invention
As shown in Figures 1 to 5, a kind of can Multi-angle free rotate cylindrical shape appearance detection device support,
The bearing unit 21 that including pallet 10, is arranged on pallet 10, it is arranged on frame by axle and bearing unit 21
Movable machine frame 30 above platform 10, described movable machine frame 30 base plate is provided with axle bed, described movable machine frame
30 are used for laying cylindrical shape appearance detection device, and described movable machine frame 30 connects with cylindrical shape appearance detection device
Contacting surface is the contact site 31 in circular shape, and described contact site 31 two ends are provided with bearing 40, and middle part is provided with
Bearing follower 50.
Being also equipped with castor 60 on described pallet 10, the quantity of described castor 60 is four, is distributed in pallet
The corner of 10.
Bearing unit 21 fitted shaft on pallet 10 is freely rotatable movable machine frame 30, and movable machine frame 30 drives
It is placed in cylindrical shape appearance detection device thereon, thus realizes cylindrical shape appearance detection device the first angle
Rotate freely;Cylindrical shape appearance detection device is placed in movable machine frame 30 by the contact site 31 of circular shape
On, the bearing 40 at contact site 31 two ends can make cylindrical shape appearance detection device around the central axis of himself
Realize rotating freely of the second angle.
Above content is only the better embodiment of the present invention, for those of ordinary skill in the art, foundation
The thought of the present invention, the most all will change, this specification content
Should not be construed as limitation of the present invention.
