Preferably, described mandrel is provided with butter at the lead to the hole site through on described cover plate.
The device of processing blades circular arc of the present invention is by carrying out fastening bearing with a nut and a back-up ring, nut screwing clamping on axle sleeve, and on nut, open a breach and come fastening nuts with holding screw, prevented the loosening of nut, between cover plate and mandrel, with butter, seal, well-done like this place is again:
One, cost are than original cover plate and gasket seal is fastening at least reduces by 50%;
Two, can reduce the gap of bearing seal, increase the life-span of bearing, solve the fastening problem that can not finely accomplish sealing of traditional approach cover plate and gasket seal;
Three, on nut, open a breach next fastening with holding screw, can well prevent the loosening of nut, protected bearing;
Four, convenient mounting and clamping saves trouble, and can increase work efficiency greatly;
Five, improve machining accuracy, guaranteed the uniformity of product.
Accompanying drawing explanation
Fig. 1 is the structural representation of the device of processing blades circular arc of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail, to make those skilled in the art can implement according to this with reference to description word.
As shown in Figure 1, the invention provides a kind of device of processing blades circular arc, it comprises: base plate 17;
Bearing holder (housing, cover) 13, it is vertically arranged on described base plate; Mandrel 9, its one end is arranged in described bearing holder (housing, cover) by least one bearing 14; Wherein, between described bearing and described base plate, be provided with a nut 15, tight fit between described nut and described bearing holder (housing, cover).
Preferably, the device of described processing blades circular arc also comprises: for fastening described nut, mark closely screw 16; Wherein said nut is provided with an opening, described in mark closely screw and be arranged on described opening part.
Preferably, the device of described processing blades circular arc also comprises: cover plate 10, and it is located on described bearing holder (housing, cover) by screw 12 lids; Wherein, described cover plate is provided with can be through the through hole of described mandrel 9, and the other end of described mandrel is through this through hole.
Preferably, described mandrel is provided with annular protrusion, is respectively equipped with clutch shaft bearing and the second bearing in the both sides of described annular protrusion; Wherein, described clutch shaft bearing 14 is near described base plate, and described the second bearing is near described cover plate.
Preferably, between described the second bearing and described cover plate, be provided with a back-up ring 11.
Preferably, the device of described processing blades circular arc also comprises: adjustable plate 1, and it is fixed on the other end of described mandrel; Wherein, on described adjustable plate, offer a plurality of screw holes.
