Description
Technical field
The present invention relates to a kind of protective devices.
Background technique
Certain large slewing parts, there are assembly relations for end face, so there are roughness, dimension precision requirement, and
These large slewing parts are easily destroyed its apparent mass and dimensional accuracy, then influence its assembly during transhipment, group weldering
Quality.
Summary of the invention
Place, the present invention provide a kind of protective device, solve huge revolving in order to overcome the above-mentioned deficiencies of the prior art
The problem of colliding with being easy to appear in the turnover of class part, welding process, improves component assembly quality.
To achieve the above object, the present invention adopts the following technical scheme: a kind of protective device, including shield, bolt, spiral shell
Female, screw thread protection cover, the shield include muti-piece protective plate, and muti-piece protective plate is combined into the shield of circular ring shape, described anti-
The surface of protection part is arranged in shield, which is equipped with multiple through-holes, and shield is fixed by through-hole, screw bolt and nut
On protection part, the back side of protection part is arranged in nut, and protective plate is equipped with screw thread that is multiple and needing part to be protected
The adaptable anti-guard aperture in hole site is equipped with screw thread protection cover in the anti-guard aperture, and the screw thread protection cover is cylindrical shape.
In the above-mentioned technical solutions, the central angle of protective plate described in muti-piece is identical.
In the above-mentioned technical solutions, the outer wall lower end of the screw thread protection cover is equipped with one section for increasing the convex of frictional force
It rises.
In the above-mentioned technical solutions, screw thread protection cover top surface is equipped with the ring flat-plate extended to outer rim, the ring flat-plate and screw thread
Protective cover is integrally formed.
In the above-mentioned technical solutions, the protective plate is bakelite plate.
It has enough to meet the need, be easy in welding process the beneficial effects of the present invention are: the protective device solves large slewing parts
The problem of colliding with occurred, improves component assembly quality, while sectional type bakelite plate being taken both to mitigate as the structure of protection board
Installation weight, reduces device materials usage amount, while enhancing protective capacities.

Specific embodiment
With reference to the accompanying drawing and specific embodiment the invention will be further described.
It is described such as a kind of Fig. 1 to protective device shown in fig. 5, including shield, bolt 2, nut 3, screw thread protection cover 4
Shield includes muti-piece protective plate 1, and muti-piece protective plate 1 is combined into the shield of circular ring shape, and the shield setting is in protection zero
The surface of part 5, the shield are equipped with multiple through-holes, and shield is fixed on protection part 5 by through-hole, bolt 2 and nut 3
On, the back side of protection part 5 is arranged in nut 3, and protective plate 1 is equipped with multiple screw thread hole site phases with need part to be protected
The anti-guard aperture adapted to, screw thread protection cover 4 is equipped in the anti-guard aperture, and the screw thread protection cover 4 is cylindrical shape.Protection part 5 be
To need large slewing parts to be protected.
In the above-mentioned technical solutions, the central angle of protective plate 1 described in muti-piece is identical.
In the above-mentioned technical solutions, the outer wall lower end of the screw thread protection cover 4 is equipped with one section for increasing the convex of frictional force
It rises.The both ends of the protrusion are equipped with chamfering.
In the above-mentioned technical solutions, 4 top surface of screw thread protection cover is equipped with the ring flat-plate 6 extended to outer rim, the ring flat-plate 6 and spiral shell
Line protective cover 4 is integrally formed.By screw thread protection cover 4 be packed into when, ring flat-plate 6 prevent screw thread protection cover 4 entirely enter protective plate 1 and
Be inconvenient to take out.Ring flat-plate 6 can be in circular ring shape or other shapes.
In the above-mentioned technical solutions, the protective plate 1 is bakelite plate.
These are only the preferred embodiment of the present invention, is not intended to restrict the invention, for those skilled in the art
For member, the invention may be variously modified and varied.All within the spirits and principles of the present invention, it is made it is any modification,
Equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
