Description
Technical field
The utility model belongs to a kind of parts of grinding machine, refers in particular to a kind of super smart head of machining bearing raceway.
Background technology
Super smart head is generally used for the surface of microstoning raceway.In the prior art, the oilstone on the super smart head generally is installed on the piston rod middle part in the oscillating mechanism, does not generally have the oilstone automatic compensation function, and can not realize the workpiece one-time positioning, thick, smart secondary is super smart, thereby, be not suitable for automatic production, in addition, and machining accuracy is also lower.
Summary of the invention
The purpose of this utility model is to design the super smart head of a kind of microstoning circular cone, cylindrical bearing raceway, and the oilstone in this super smart head is provided with compensation mechanism, and can realize one-time positioning, that thick essence surpassed for two steps is super smart.
According to design provided by the utility model, piston is arranged in cylinder body, the piston rod on the piston stretches out cylinder cap, and at the overhanging end of piston rod the pressing plate that is used to connect oilstone is installed.
In the side of cylinder body guide rod in axial sliding is set, and this guide rod is approximate parallel with piston rod, the end of guide rod is connected with pressing plate.Cylinder body has two, in the piston rod outer end of each cylinder body pressing plate is installed respectively, and oilstone is installed respectively on two block pressur plates.The end of oilstone is passed the through hole on the oilstone frame that is positioned at the place ahead respectively.
On pressing plate, connect the sender switch.The one end bending in opposite directions respectively of oilstone is installed on two pressing plates that are parallel to each other, and oilstone lays respectively at the end of bending, and, two approximate being on the same axis of oilstone.
The utility model has the advantages that be installed on oilstone on the cylinder piston bar after, when carrying out microstoning, all the time be subjected to one thrust on the oilstone, this burst thrust can guarantee that oilstone and workpiece are in the excellent contact state all the time, in traditional microstoning process, owing to do not have the cylinder piston mechanism of this redeeming, thereby, be difficult to control the contact condition of oilstone and workpiece, influenced the superlinishing effect; Secondly, because this device respectively simultaneously is installed on the piston rod of two cylinder bodies on, therefore with smart super oilstone slightly super oilstone, when the feed mechanism feeding, can realize the workpiece one-time positioning, it is super smart that thick, essence surpassed for two steps, thereby improved positioning accuracy, simplified manufacturing procedure.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is the A-A view of Fig. 1.
The specific embodiment
As shown in the figure: piston 5 is arranged in cylinder body 2, and the piston rod on the piston 5 stretches out cylinder cap 6, and at the overhanging end of piston rod the pressing plate that is used to connect oilstone is installed.During work, oilstone is installed on pressing plate, and oilstone is contacted with workpiece, in the process of Work piece high-speed rotation, oilstone carries out microstoning to it.Because oilstone is installed on the piston rod of cylinder body 2, therefore, along with oilstone constantly is worn to the grinding of workpiece, piston can constantly advance oilstone, makes oilstone press workpiece all the time, and workpiece is carried out accurately and effectively grinding.
Utilize bearing setting guide rod 1 in axial sliding in the side of cylinder body 2; lining 3 is set between two bearings; with location bearing; guide rod 1 should be similar to parallel with piston rod; the end of guide rod 1 is connected with pressing plate; the effect of guide rod is to guarantee that piston rod does rectilinear motion accurately, avoids having influence on machining accuracy because of shake.
Cylinder body 2 has two, piston rod outer end at each cylinder body 2 is installed pressing plate 8 and 7 respectively, thick super oilstone 9 and smart super oilstone 10 are installed respectively on two block pressur plates 8 and 7, so just super oilstone of essence and thick super oilstone one-time positioning can be installed, in original technology, must carry out earlier slightly surpassing, behind thick super the finishing, pull down thick super oilstone again, smart super oilstone is installed then, when oilstone being installed, all must carry out accurate localization, this can increase the workload of installation undoubtedly and reduce positioning accuracy at every turn, this device is realized one-time positioning, slightly, essence has improved positioning accuracy after surpassing super essence of two steps, has reduced the workload of installing with the location.
The end of oilstone 9,10 is passed the through hole on the oilstone frame 11 that is positioned at the place ahead respectively, so that make oilstone in grinding process, can obtain good guidance and location.On pressing plate 8,7, connect sender switch 12, be used at oilstone wearing and tearing or fracture back sender, lathe autostop.
The one end bending in opposite directions respectively of oilstone is installed on two pressing plates that are parallel to each other 8 and 7, oilstone lays respectively at the end of bending, so just can make two blocks of oilstones after installing, approximate being on the same axis, this root axis is generally the machining center of workpiece, after two blocks of oilstones lay respectively on the same axis, help the location and install.
