Description
Technical field
The present invention relates to engine cavity shell abrasor technical fields, and in particular to a kind of hand-held engine chamber shell polishing
Machine.
Background technique
Engine (Engine) be it is a kind of can be the machine that can be converted into mechanical energy of other forms, including such as internal combustion engine
(petrol engine etc.), external-combustion engine (Stirling engine, steam engine etc.), motor etc..If internal combustion engine is usually chemical energy
It is converted into mechanical energy.Engine is not only suitable for power generating apparatus, also can refer to include power device entire machine.
Wherein carrier of the chamber shell of engine as entire engine assembly, wherein engine is in production, transit chamber shell
It is carried out to assemble relevant part, wherein engine cavity shell during fabrication, be mostly using casting by the way of, wherein need by
The raw material of fluidised form, which is injected into sand mold mould, carries out casting forming, finally again separates the chamber shell of forming with sand mold mould.
Engine housing is rough after die cast, and not only there are many scabs, but also have more hair
Thorn first can carry out ball blast to the engine housing after die cast under normal circumstances, then be roughly ground and be refined, but due to being
Entity casting, heavier mass, it is very painstaking to polish after artificial overturning, and not only operator is arduous, but also reduces enterprise's production effect
Rate, especially medium-and-large-sized special engine shell, if being refined by artificial overturning engine housing, not only polishing is imitated
Rate is extremely low, and some edges are even more that can not set about to polish.Nowadays a small number of enterprises fill using tooling
After pressing from both sides engine housing, then row polishing, but since its device clamping is not sufficiently stable, make engine housing rolling occur when polishing
It is dynamic, it is difficult to guarantee its grinding accuracy
China State Intellectual Property Office discloses the patent application No. is 201821349561.2, which includes motor,
The leading exterior surface of the motor is fixedly installed with gear-box, and the upper end outer surface of gear-box is provided with lock spindle, the tooth
The lower end outer surface of roller box is fixedly connected with connected unit, and the lower end outer surface of connected unit is movably installed with grinding wheel, the connection
One side external surface of platform is fixedly installed with shield.The utility model is using the present apparatus by being provided with a series of structure
In the process, conducting wire can be stored convenient for user first, conducting wire is effectively protected, it is facilitated to carry polishing dress
It sets, secondly effectively grinding wheel can be protected, avoid increasing its safety used there is a phenomenon where grinding wheel incised wound user
Property, additionally being able to the clast for preventing from generating when polishing influences the progress of polishing work, increases the uniformity of its raw material of polishing, excellent
Change use process.
As the device also gradually exposes the deficiency of the technology during polishing engine cavity shell, mainly
It is embodied in the following aspects:
First, wherein being limited to the grinding wheel of high-speed rotation when being polished again the burr of chamber shell using the grinding tool, making
The burr and sand that must be polished off easily adhere on chamber shell others surface, so that secondary scratch easily is caused to the surface of chamber shell,
Be also inconvenient for after adherency burr and sand clear up, increase the output of the amount of labour, and by the polishing of high-speed rotation
So that the burr and sand thrown are it is easier that periphery working environment becomes muddy, the processing for influencing operator uses wheel.
Second, lumen shell is interior to be equipped with many channels even groove, this cannot be introduced into the grinding wheel to the space
It is interior, it is not easy to carry out grinding process to internal surface, so that can not polish to such position, so that also needing operator
Later-stage utilization rasp is surface-treated, and working efficiency greatly reduces, and extend the working time.
Third, after wherein grinding wheel polishes for a long time to chamber shell surface, wherein the burr and sand after polishing easily adhere to
To between the hairbrush of grinding wheel, so that easily limiting the displacement between hairbrush over time, hairbrush is thereby reduced to chamber shell
Polishing quality, and be adhered to the burr on hairbrush and sand and also easily occur with chamber shell surface in the state of grinding wheel high-speed rotation
Secondary contact causes friction to scratch on surface.
Operator's problem encountered during taking out chamber shell above, wherein research staff be around how
The burr and sand on chamber shell surface are removed, but has ignored and is limited to the in irregular shape of chamber shell, so that in hole and groove
It is interior that rasp is needed to polish；Burr and sand after polishing are easily adhered to chamber shell other surfaces again and scratch to it；With
And polishing after burr and sand be easily adhered in grinding wheel, by its grinding wheel burr and sand are easily caused to chamber shell surface
The phenomenon that secondary scratch.
From the foregoing, it will be observed that the existing technology has inconveniences and defects in actual use, so it is necessary to be improved.
