Description
Technical field
The utility model relates to a kind of grinder parts, the universal platen device of especially a kind of grinder.
Background technology
Grinder is on the mode of exerting pressure at present, and using more all is the loaded with standard counterweight that uses certain mass.There is following shortcoming in this load mode: the one, and counterweight is relatively heavier, has not only increased greatly workman's workload when using manpower to load, and can make the workman tired, easily generation accident; The 2nd, the weight of counterweight all is specific, can't satisfy needed different loading forces in the different process situation.For a change this situation is enhanced productivity, and adopts the cylinder pressuring method to replace the load mode of manually-operated counterweight, and the size of pressure is regulated by the control valve in the control pressurer system, and is simple and quick.
Grinder cylinder compression system comprises cylinder, main shaft, pressure head, anchor clamps, the anchor clamps holding workpiece, and cylinder moves up and down pressure head, anchor clamps and workpiece by main shaft, and workpiece is applied grinding pressure.In process of lapping, pressure head-anchor clamps-workpiece-abrasive disk upper surface is close contact all the time between any two.So, want to realize the high precision plane grinding of workpiece, except the precision that will guarantee abrasive disk, also to guarantee the even applying of workpiece and abrasive disk upper surface, pressure is identical everywhere to make surface of the work, and grinding rate is identical everywhere.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and drive anchor clamps and workpiece universal swing, reaches the purpose of evenly fitting with the abrasive disk upper surface, the universal platen device of grinder of realizing the high precision plane grinding.
The technical scheme that provides according to the utility model, the universal platen device of described grinder, upper surface at cylinder mounting plate is fixed with cylinder, lower surface at cylinder mounting plate is fixed with axle sleeve, in axle sleeve, be slidingly fitted with apical axis, the piston rod of cylinder links to each other with the top ends of apical axis, bottom at apical axis is fixed with eccentric shaft, the coxopodite section of eccentric shaft is provided with external screw thread, coxopodite section at eccentric shaft is bolted with mounting nuts, be set with self-aligning bearing on the inferior coxopodite section of eccentric shaft, inner ring body bottom face and the mounting nuts of self-aligning bearing offset, and the eccentric shaft above self-aligning bearing is socketed with bearing cap, outer ring body top end face and the bearing cap of self-aligning bearing offset, outer ring body at self-aligning bearing is socketed with presser feet, and presser feet is fixedly connected with bearing cap, fixedly is embedded with the presser feet dish in presser feet.
As preferably, be fixed with guide pin bushing in the inside, upper end of axle sleeve with inside, lower end, described apical axis sliding plug is in guide pin bushing.
Be further used as preferably, be connected to telescopic protective cover in the outer cover of axle sleeve.
As preferably, be provided with low protection cover in the periphery of eccentric shaft and bearing cap, low protection cover and eccentric shaft are fixed, protective cover on low protection cover is fixed with; The bottom of described telescopic protective cover and the top end face of upper protective cover offset.
The utlity model has following advantage:
1, the utility model adopts self-aligning bearing, and platen can drive anchor clamps and workpiece universal swing, reaches the purpose of evenly fitting with the abrasive disk upper surface, realizes the high precision plane grinding;
2, the utility model adopts the cylinder pressurization, can regulate pressure-regulating valve according to needed different loading forces in the different process situation, gives different pressure, improves grinding rate and precision.
