Fig. 1 is the clamping mechanism structural representation for workpiece single-sided polishing;
Fig. 2 is that Fig. 1 midplane is passed power supporting structure schematic diagram;
Fig. 3 is vertical pressurizing frame structural representation in Fig. 1;
Mark in above-mentioned figure is: 1, pressure head; 2, plane is passed power support; 3, nut; 4, vertical pressurizing frame; 5, carrier; 6, polishing pad; 7, polishing disk; 21, slideway.
The specific embodiment
Known referring to Fig. 1, for the clamping mechanism of workpiece single-sided polishing, being one fixes polishing workpiece, and by polishing workpiece to the frock pressing down on the polishing pad of polishing mechanism, polishing mechanism is existing equipment, generally include motor, be fixed on the polishing disk 7 on machine shaft, and be bonded in the polishing pad 6 on polishing disk 7.
Clamping mechanism comprises that pressure head 1, plane pass power support 2, vertical pressurizing frame 4 and carrier 5.
Plane is passed power support 2 and is comprised center fixed leg, and in edge, mind-set fixed leg is radially extended with several poles to surrounding, these poles wait angle to distribute conventionally, to guarantee equipment stress equalization, working stability, embodiment as shown in Figure 2, one has three poles, and the plane that mutual angle is 120 degree is passed power support 2.
Each plane is passed on power support 2 poles and is all fixed with a vertical pressurizing frame 4, and vertical pressurizing frame 4 one end are connected with pole, and the other end is towards the polishing pad of polishing mechanism, and this end is provided with the groove for fixing carrier 5.For the convenient center distance that regulates adjustment workpiece and polishing disk 7 is eccentric throw, on every pole, along its extension, be provided with slideway 21, as shown in Figure 3, vertical pressurizing frame 4 is provided with pole link can be through the screw rod of slideway 21, and be fixed on pole slideway 21 by nut 3, nut 3 can be the standard component of M6.And on each slideway 21, can also preset scale, when regulating the center distance of adjusting workpiece and polishing disk 7, can, according to scale, regulate more accurately like this.
Polishing workpiece is the center that the paraffin after utilization heating sticks on carrier, and cooling, make it fixing, the thickness that is stained with the carrier 5 of polishing workpiece is slightly less than the degree of depth of the groove of vertical pressurizing frame 4, and the planar dimension of groove can be according to the change of shape of workpiece.
