Description
Technical field
The utility model belongs to work pieces process technical field, and in particular to a kind of Large Crankshaft processing grinding tool.
Background technology
The large-scale straight side double crank press of our company's autonomous Design production, product deadweight have 8 to 10 tons, and bent axle is the lathe
One of vital part, crank shaft blank single-piece is heavier, and length is longer, and crankshaft stroke is larger, and eccentric rotary diameter is bigger than normal.Two bent axles
Crank throw is very high to the depth of parallelism of each shelves and two crank throw eccentric throw Geometrical Tolerance Principles, if not reaching design requirement, will influence should
The synchronism required precision of lathe.After accomplishing that uniformity, technological requirement two pieces bent axle answer disjunctor processed finished products, then from interposition
Put sawed-off, the flat both ends of the surface of lathe, turn into two uniformity bent axles, so process to difficulty is added in production, because lathe half
After smart car, fine cylindrical on bent axle peripheral milling need to be gone up.But the bent mill equipment of the fine grinding of so large-scale bent axle can be met,
Almost it is difficult to find, and remove from lathe and to be put into that processing transfer workpiece on grinding machine is heavy and clamping complex procedures again；If adopt
With on lathe smart car improve crankshaft surface finish, because crank up is eccentric big, turning property is larger, and lathe speed is lifted not
Come up, finish is unable to reach design requirement.
The content of the invention
The purpose of this utility model is to overcome that Large Crankshaft fine grinding demand, lathe smart car can not be completed in the prior art
A kind of the defects of being unable to reach smoothness requirements again, there is provided Large Crankshaft processing mill that directly can be refined on lathe
Tool.
Technical scheme is used by the utility model solves its technical problem：
A kind of Large Crankshaft processing grinding tool, on the knife rest of lathe, it is characterised in that：Including support, motor,
Driving pulley, driven pulley, driving belt, power transmission shaft, bearing block, bearing and bistrique, when carrying out fine grinding to Large Crankshaft,
The support is fixedly connected on the knife rest, the shell and bearing block of the motor are each attached on the support, institute
It is coaxially connected to state the output shaft of driving pulley and the motor, the driven pulley and bistrique are coaxially connected by power transmission shaft,
The power transmission shaft is erected on the bearing block by bearing, and the driving pulley is connected by driving belt and the driven pulley
Connect.
Further, the bistrique is grinding wheel.
Further, the bistrique is polishing disk.
Further, the support is bolted on the knife rest.
Relative to prior art, the utility model has an advantageous effect in that：After bent axle carries out semifinishing on lathe,
Heavy bent axle need not be taken down and change other machine tooling, this Large Crankshaft processing grinding tool only need to be installed on knife rest, use
Motor drives grinding wheel to carry out being ground to upper deviation requirement by shelves, grinding wheel then is changed into polishing disk, then each gear is carried out
Surface polishes.Reduce the risk to being damaged caused by the transfer of Large Crankshaft, and semifinishing, grinding and polishing add
Work machines on same lathe, greatlys save the expense of purchase of equipment, and simplifies processing technology.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is lathe front view of the present utility model；
Fig. 2 is the top view for installing lathe after grinding tool after Large Crankshaft is processed.
In figure：1st, knife rest, 2, support, 3, motor, 4, driving pulley, 5, driven pulley, 6, driving belt, 7, transmission
Axle, 8, bearing block, 9, bearing, 10, bistrique, 11, bent axle, 12, lathe.
Embodiment
The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram,
Only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the composition relevant with the utility model.
, it is necessary to which explanation, unless otherwise clearly defined and limited, term " are pacified in description of the present utility model
Dress ", " setting ", " connection " should be interpreted broadly, for example, it may be fixedly connected or be detachably connected, or integratedly
Connection；Can be joined directly together, can also be indirectly connected by intermediary.For the ordinary skill in the art,
Concrete meaning of the above-mentioned term in the utility model can be understood as the case may be.
Large Crankshaft processing of the present utility model as depicted in figs. 1 and 2 is arranged on the schematic diagram on lathe 12 with grinding tool,
Large Crankshaft processing need to be arranged on the knife rest 1 of lathe 12 with grinding tool and be worked, and Large Crankshaft processing grinding tool includes support 2, electricity
Motivation 3, driving pulley 4, driven pulley 5, driving belt 6, power transmission shaft 7, bearing block 8, bearing 9 and bistrique 10, motor 3 it is outer
Shell and bearing block 8 are each attached on support 2, and the output shaft of driving pulley 4 and motor 3 is coaxially connected, driven pulley 5 and bistrique
10 is coaxially connected by power transmission shaft 7, and power transmission shaft 7 is erected on bearing block 8 by bearing 9, and driving pulley 4 passes through driving belt 6
It is connected with driven pulley 5.
Bistrique 10 can be grinding wheel or polishing disk as needed.
After Large Crankshaft 11 completes half smart car on lathe 12, grinding tool of the present utility model is fixedly mounted on lathe 12
On knife rest 1, now the bistrique 10 on grinding tool is grinding wheel, and the motor 3 of high-speed rotation drives grinding wheel to rotate by V belt translation
The surface of revolution of Large Crankshaft 11 is carried out being ground to upper deviation requirement by shelves, then changes grinding wheel into polishing disk, then to bent axle
11 each shelves are polished.Save trouble and labor, it is practical.
It should be appreciated that specific embodiment described above is only used for explaining the utility model, it is not used to limit this reality
With new.By the obvious changes or variations that spirit of the present utility model is extended out still in protection of the present utility model
Among scope.
