Description
Technical field
The utility model belongs to grinding head technical field, and in particular to a kind of grinding head of adjustable size.
Background technique
What is played a crucial role in material polishing is grinding head, and grinding head is a kind of general name of mini zone handle grinding tool, is answered
For electrical grinding machine, grinding machine and electric hand drill are hung, type much mainly has ceramic bistrique, rubber bistrique, diamond grinding head and sand
Cloth bistrique etc..
Currently, inner wall of the pipe grinding head has the following problems in use: 1, grinding head is after a protracted use
It will lead to grinding head damage, therefore grinding head needs to replace it after work lengthens the time, keeps its grinding effect
Normally, and grinding head integral replacing causes the increase of certain waste and cost.2, sander is different when polishing inner wall of the pipe
The hole of size, it is necessary to different size of grinding head, and replace grinding head and waste time, while reducing working efficiency,
And increase operation cost.
Utility model content
The utility model solves the deficiencies in the prior art, provide a kind of replacement of grinding disc is convenient, grinding head size can be with
The grinding head of adjusting.And structure is simple, work efficiency is high.
The technical scheme adopted by the utility model is a kind of grinding head of adjustable size, the grinding head includes circle
Axis, sleeve and grinding disc, the sleeve are tubular structure, several rectangular through holes, the circular shaft is distributed in even circumferential
It is arranged in sleeve, the circular shaft includes center circular shaft and several cones, and the cone is sheathed on the circular shaft of center, institute
It states grinding disc to be set in rectangular through holes, the grinding disc includes grinding disc ontology, and grinding disc ontology one end is provided with
Frosted item, the other end are provided with several right angle v notch vs, and the right angle v notch v is equidistantly arranged with cone, the circle
Cone is embedded in right angle v notch v.
Preferably, the frosted item is fabricated from a flexible material.
It is further preferred that the slope ratio of the right angle v notch v is 1:5, and the slope ratio and circular cone of the right angle v notch v
Body slope is than identical.
Still more preferably, the grinding disc ontology is process by titanium alloy material.
Compared to the prior art, the utility model has the advantages that by setting circular shaft, sleeve and grinding disc, both
The function of realizing polishing inner wall of the pipe, in turn simplifies structure and improves work efficiency；The polishing of the extension type of setting
Piece solves the problems, such as that different size inner wall of the pipe needs different grinding heads, and the replaceable abrasive segments being arranged, and reducing makes
Use cost.
Detailed description of the invention
Fig. 1 is the utility model structure diagram；
Fig. 2 is the utility model sleeve cross-sectional view；
Fig. 3 is the utility model grinding disc structural schematic diagram；
Fig. 4 is the utility model circular shaft cross-sectional view.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of grinding head of adjustable size, refering to fig. 1, Fig. 2, Fig. 3 and Fig. 4, the grinding head includes circular shaft 3, sleeve 1
With grinding disc 2, the sleeve 1 is tubular structure, several rectangular through holes 11 are distributed in even circumferential, and the circular shaft 3 is worn
In sleeve 1, the circular shaft 3 includes center circular shaft 31 and several cones 32, and the cone 32 is sheathed on center circle
On axis 31, the grinding disc 2 is set in rectangular through holes 11, and the grinding disc 2 includes grinding disc ontology 21, the grinding disc
21 one end of ontology is provided with frosted item 22, and the other end is provided with several right angle v notch vs 23, the right angle v notch v 23 with
Cone 32 corresponds, and the cone 32 is movably embedded in right angle v notch v 23.
In order to play buffer function when polishing, the frosted item 22 is fabricated from a flexible material.
In order to allow polishing 2 slowly to strut outward, refering to fig. 1, the slope ratio of the right angle v notch v 23 is 1:5, and described
The slope ratio of right angle v notch v 23 is with 32 slope of cone than identical.
The grinding disc ontology 21 is process by titanium alloy material.
Described 3 one end of circular shaft is moved forward by a constant force, circular shaft 3, and circular shaft 3 passes through the cone 32 on circular shaft
Grinding disc 2 is strutted outward, after grinding disc 2 and inner wall of the pipe contact, starts to polish, on frictional resistance and circular shaft 3 at this time
Constant force reach balance, when frosted item 22 is polished after a period of time, frosted item 22 is thinning, frictional resistance reduce, this
When circular shaft 3 on constant force push circular shaft 3 to move forward, the grinding disc 2 that the cone 32 on circular shaft 3 continues to press on continue to
It struts outside, reaches new balance, repeatedly.
When 22 thickness of abrasive segments is less than the 1/3 of original thickness, new abrasive segments 22 are needed replacing.
Above-described embodiment, the only preferred embodiment of the utility model not are used to limit the implementation model of the utility model
It encloses, therefore all equivalent variationss done with content described in the utility model claims, the utility model right should all be included in and wanted
Within the scope of asking.
