Abstract
The utility model discloses a kind of grinding tool, comprise powered rotation electric motor units, emery wheel, turning handle; Described emery wheel comprises the first abrading block and the second abrading block that keep at a certain distance away, and described first abrading block becomes round pie with the second abrading block, and the center of described emery wheel is provided with through hole, and one end of described turning handle is fastening to be arranged in described through hole; The other end of described turning handle is connected with the rotating shaft of the motor of described powered rotation electric motor units by an axle sleeve; One end that described powered rotation electric motor units is connected with described turning handle is provided with a shaped hollow round table locating part, and described locating part is being symmetrically arranged with four limited posts away from described powered rotation electric motor units.By design a kind of have keep at a certain distance away and become the first abrading block of round pie and the emery wheel of the second abrading block, can process double-ring groove to the hole on a part, and working (machining) efficiency is improved, precision is also guaranteed simultaneously.
Description
Technical field
The utility model relates to grinding technique field, particularly relates to a kind of grinding tool.
Background technology
Grinding tool is the instrument in order to grinding, grinding and polishing.Most grinding tool adds with abrasive material the artificial grinding tool that bonding agent is made, also the natural grinding tool that is directly processed into of useful natural ore rock.Grinding tool except being widely adopted in machine-building and other metal-processing industries, also for the processing of the nonmetallic materials such as grain processing, paper industry and pottery, glass, stone material, plastics, rubber, timber.
If the hole on a part processes annular ditch groove also can utilize grinding tool.If but the hole machined on a part goes out double-ring groove (consulting Fig. 1), utilize common grinding tool not only to waste time and energy, and working (machining) efficiency is low, precision also can not be guaranteed.
Utility model content
In view of above content, the utility model provides a kind of grinding tool that simultaneously can process double-ring groove to the hole on a part.
For achieving the above object, the utility model solves the technical scheme that its technical problem adopts and is:
A kind of grinding tool, comprises powered rotation electric motor units, emery wheel, turning handle; Described emery wheel comprises the first abrading block and the second abrading block that keep at a certain distance away, and described first abrading block becomes round pie with the second abrading block, and the center of described emery wheel is provided with through hole, and one end of described turning handle is fastening to be arranged in described through hole; The other end of described turning handle is connected with the rotating shaft of the motor of described powered rotation electric motor units by an axle sleeve; One end that described powered rotation electric motor units is connected with described turning handle is provided with a shaped hollow round table locating part, and described locating part is being symmetrically arranged with four limited posts away from described powered rotation electric motor units.
Due to the utilization of technique scheme, the utility model compared with prior art has following beneficial effect:
By design a kind of have keep at a certain distance away and become the first abrading block of round pie and the emery wheel of the second abrading block, can process double-ring groove to the hole on a part, and working (machining) efficiency is improved, precision is also guaranteed simultaneously.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the partial sectional view of the double-ring trench portions needing in background technology to process on part.
Fig. 2 is the structural representation of a kind of grinding tool of the utility model.
Fig. 3 is the front view of a kind of grinding tool medium plain emery wheel of the utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, content of the present utility model is described in further detail:
Consult Fig. 2 and Fig. 3, a kind of grinding tool, comprise powered rotation electric motor units 1, emery wheel 4, turning handle 5; Described emery wheel comprises the first abrading block 41 and the second abrading block 42 kept at a certain distance away, and described first abrading block becomes round pie with the second abrading block, and the center of described emery wheel is provided with through hole, and one end of described turning handle is fastening to be arranged in described through hole; The other end of described turning handle is connected with the rotating shaft of the motor of described powered rotation electric motor units by an axle sleeve; One end that described powered rotation electric motor units is connected with described turning handle is provided with a shaped hollow round table locating part 2, and described locating part is being symmetrically arranged with four limited posts 3 away from described powered rotation electric motor units.
The simple course of work:
Aimed at by emery wheel and need the hole of processing parts, to be deep in machining hole, the outside of withstanding machining hole by the limited post of locating part after being deep into machining hole prevents emery wheel in grinding process deeply too much, ensure that crudy.
Above-described embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
