Abstract
The utility model discloses a kind of bicircular arcs forming grinding wheel burring machine, comprise grinding subassembly and feeder assembly, the abrading article that described grinding subassembly comprises motor and is connected with motor, described feeder assembly comprises power drive mechanism and is connected to the emery wheel on power drive mechanism, described abrading article is two diamond rollers, lays respectively at both sides above emery wheel.Adopt each shaping diamond roller in left and right, the swing of conditioning arm is replaced to carry out trimming wheel by the rotation of roller, emery wheel both sides are distributed in due to diamond roller symmetry, side force suffered by emery wheel is made evenly to be unlikely to cracked, diamond roller the arc surface even accuracy of manufacture of arbitrary surface can be ensured again simultaneously, thus ensure that the precision to crushing, improve the cutting ability of micro-brill.
Description
Technical field
The utility model relates to technical field of mechanical equipment, particularly a kind of bicircular arcs forming grinding wheel burring machine.
Background technology
When the micro-auger shell spin slot of grinding, need two sections of circular arcs abrasive wheel end face shape being become left and right different radii, take two conditioning arm front ends in left and right to insert diamond pen respectively at present during our large gauge bit grinding ditch, by the length that adjustment diamond pen stretches out, when conditioning arm swings, the movement locus of Buddha's warrior attendant nib is exactly the different circular arc of radius, and the abrasive wheel end face like this after finishing forms the arc surface of two sections of different radiis.The grinding wheel thickness used due to micro-brill grinding is very thin, take the form trimming wheel of conditioning arm, first disc wheel because of both sides unbalance stress frangible, secondly arc accuracy can not ensure, therefore, can only replace circular arc to repair two straight lines, the drill bit main cutting edge ground like this is the straight line that camber line instead of drill bit require, has influence on the cutting ability of drill bit.
Summary of the invention
The purpose of this utility model is to provide a kind of bicircular arcs forming grinding wheel burring machine, both avoided because of emery wheel thin repair time frangible problem, in turn ensure that the dressing accuracy of disc wheel circular arc end surface shape, improve micro-brill precision and cutting ability.
To achieve these goals, the utility model adopts following technical scheme: a kind of bicircular arcs forming grinding wheel burring machine, comprise grinding subassembly and feeder assembly, the abrading article that described grinding subassembly comprises motor and is connected with motor, described feeder assembly comprises power drive mechanism and is connected to the emery wheel on power drive mechanism.
Further, described power drive mechanism is made up of transmission main shaft and driving pulley, and described belt pulley is connected to one end of transmission main shaft, and described emery wheel is arranged on the other end of transmission main shaft.
Further, described emery wheel and described transmission main shaft pass through Flange joint.
Further, described abrading article is diamond roller.
Further, described grinding subassembly quantity is two, and described motor comprises the first motor and the second motor, and described first motor is connected with the first diamond roller, and described second motor is connected with the second diamond roller.
Further, described two diamond roller assemblies lay respectively at both sides above feeder assembly.
Above emery wheel, the diamond roller of a different arc radius is respectively installed in both sides, when emery wheel needs reconditioning, transmission main shaft rises, drive emery wheel from grinding position to touching diamond roller arc surface position, then start reconditioning, after reconditioning terminates, transmission main shaft declines, make emery wheel depart from reconditioning position, after reconditioning, recover sharp emery wheel can carry out grinding again.
The utility model compared with prior art, there is following beneficial effect: adopt each shaping diamond roller in left and right, the swing of conditioning arm is replaced to carry out trimming wheel by the rotation of roller, because diamond roller is symmetrically distributed in both sides before and after emery wheel, side force suffered by disc wheel is evenly unlikely to cracked, the dressing accuracy of disc wheel circular arc end surface shape can be ensured again, thus improve micro-brill precision and cutting ability.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of bicircular arcs forming grinding wheel of the utility model burring machine;
Fig. 2 is the side view of a kind of bicircular arcs forming grinding wheel of the utility model burring machine.
In figure: the first motor 1, second motor 2, driving pulley 3, first diamond roller 4, second diamond roller 5, transmission main shaft 6, flange 7, emery wheel 8.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Fig. 1 and 2, a kind of bicircular arcs forming grinding wheel of the utility model burring machine, comprise grinding subassembly and feeder assembly, the abrading article that described grinding subassembly comprises motor and is connected with motor, described motor comprises the first motor 1 and the second motor 2, described abrading article comprises the first diamond roller 4 and the second diamond roller 5, and described first motor 1 is connected with the first diamond roller 4, and described second motor 2 is connected with the second diamond roller 5.
Described feeder assembly comprises power drive mechanism and is connected to the emery wheel 8 on power drive mechanism, described power drive mechanism is made up of transmission main shaft 6 and driving pulley 3, described belt pulley 3 is connected to one end of transmission main shaft 6, described emery wheel 8 is arranged on the other end of transmission main shaft 6, and described emery wheel 8 is connected by flange 7 with described transmission main shaft 6.
Described two diamond roller assemblies lay respectively at both sides above feeder assembly.
Above emery wheel 8, both sides are respectively provided with the diamond roller of different arc radius, diamond roller is rotated with the speed of 3,000 turns per minute by motor, the linear velocity of emery wheel 8 is about 60 ~ 80 meter/second, when emery wheel 8 needs reconditioning, transmission main shaft 6 rises, and drives emery wheel 8 from grinding position to reconditioning touching diamond roller arc surface position, after reconditioning terminates, transmission main shaft 6 declines, and makes emery wheel 8 depart from reconditioning position, recovers sharp emery wheel 8 and can carry out grinding again after reconditioning.Because diamond roller is symmetrically distributed in both sides before and after emery wheel 8, side force suffered by disc wheel 8 is evenly unlikely to cracked.Diamond roller the arc surface even accuracy of manufacture of arbitrary surface can be ensured completely again simultaneously, thus ensure that the precision to crushing, improve the cutting ability of micro-brill.
