Detailed description of the invention
As shown in Figure 1, Superfinishing machine oilstone clamping device, comprises oil stone clip housing.Described oil stone clip housing lower end is tapered, is provided with oil stone clip in oil stone clip housing, and oil stone clip hollow is for placing oilstone, and oil stone clip lower end is multijaw cone-shaped, and the conical section of oil stone clip lower end has multiple groove, makes oil stone clip lower end be multijaw cone-shaped.In the present embodiment, piston type oil stone clip conical section has 4 grooves.Oil stone clip sidewall is provided with groove, and the oil stone clip housing corresponding with groove is provided with guider screw.Guider screw is provided with nut.
The sidewall of oil stone clip housing is provided with two air inlet/outlets, and on the oil stone clip between two air inlet/outlets, cover has sealing ring.On the position corresponding with air inlet/outlet, oilstone is folded with groove.Two air inlet/outlets are connected with pressure cylinder respectively.Oil stone clip housing upper end is provided with gland, is provided with sealing ring between oil stone clip housing and gland.Oil stone clip protrudes upward gland, and oilstone advances depression bar to compress the oilstone being positioned at oil stone clip hollow position, and oilstone advances depression bar to be connected with oilstone propulsion cylinder.On oil stone clip above two air inlet/outlets, cover has sealing ring.Oilstone propulsion cylinder is arranged on oil stone clip housing.
Oilstone is machining tool.Bearing ring or roller are workpieces to be processed.In process, the front end of oilstone and bearing ring or roller treat that fine abrasive face contacts, oil stone clip makes the conical surface of oil stone clip head and the taper-face contact of oil stone clip enclosure interior under the promotion of proper amount of gas pressure.Again because the conical section of oil stone clip head has four grooves, the conical surface of oil stone clip oil stone clip under the promotion of air pressure is squeezed and shrinks, thus clamps oilstone and do not leave gap.Like this, machining accuracy and surface quality can effectively be improved in process.Because oilstone in use can shorten because of wearing and tearing, oilstone advances depression bar under the effect of oilstone propulsion cylinder, be pressed in the rear end of oilstone, makes oilstone front end keep tightly contacting with bearing ring or roller fine abrasive face and not depart from all the time in process.
Guider screw, by being screwed at oil stone clip housing, ensures that oil stone clip does straight reciprocating motion in radial directions.Nut, by being screwed on guider screw, is used for fixing guider screw.Adjusted the air pressure that oil stone clip is applied by two air inlet/outlets, control oil stone clip and do straight reciprocating motion in radial directions, and then control oil stone clip to the clamping degree of oilstone.When air inlet/outlet A is greater than the gas pressure of air inlet/outlet B, oil stone clip retreats, and now oilstone can take out from oil stone clip.When air inlet/outlet B is greater than the gas pressure of air inlet/outlet A, push away before oil stone clip, oil stone clip clamping oilstone.
Before processing, the atmospheric pressure applied oil stone clip by two air inlet/outlets is comparatively large, and make the conical section of oil stone clip tightly clamp oilstone, the insufficient pressure of oilstone propulsion cylinder is to promote oilstone.Now, workpiece to be processed material loading, be put into Working position,
In process, this device is fed into appropriate location, and what make the front end of oilstone and bearing ring or roller treats that fine abrasive face contacts, and oil stone clip makes the conical surface of oil stone clip head and the taper-face contact of oil stone clip housing under the promotion of little atmospheric pressure.Again because the conical section of oil stone clip head has four grooves, the conical surface of oil stone clip oil stone clip under the promotion of air pressure is squeezed and shrinks, thus clamp oilstone and do not leave gap, but now oil stone clip is less at atmospheric pressure, and the pressure of oilstone propulsion cylinder is enough to promote oilstone.Like this, machining accuracy and surface quality can effectively be improved in process.Because oilstone in use can shorten because of wearing and tearing, oilstone advances depression bar under the effect of oilstone propulsion cylinder, be pressed in the rear end of oilstone, makes oilstone front end keep tightly contacting with bearing ring or roller fine abrasive face and not depart from all the time in process.This device moves along certain track, thus realizes the superfinishing of bearing ring or roller.
After completion of processing, increased the atmospheric pressure that oil stone clip applies by two air inlet/outlets, make oil stone clip conical section tightly clamp oilstone, the insufficient pressure of oilstone propulsion cylinder is to promote oilstone.Now, this device exits Working position.Now, workpiece to be processed blanking, take out from Working position.
Finally should be noted that: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit; Although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the field are to be understood that: still can modify to the specific embodiment of the present invention or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solution of the present invention, it all should be encompassed in the middle of the technical scheme scope of request of the present invention protection.
