Description
Technical field
The utility model relates to a kind of cutting machine, particularly relates to a kind of cutting machine turning axle.
Background technology
In opticglass production process, many product needed are through secondary processing to obtain the product of specified dimension and to remove product defects, and this can use cutting machine product is cut.Existing cutting machine turning axle as shown in Figure 1-Figure 3, is divided into rotating part and stationary part, and rotating part is comprised of main shaft 1, flange 2, cutter 3, cutter holder 4, and stationary part is comprised of bearing 5, bearing support 8, nut 6, fastening slide block 7.Wherein, main shaft 1 is step shaft, and main shaft 1 is engaged in bearing 5, bearing 5 is fixed on bearing support 8, and nut 6 and bearing 5 thread fit, for regulating the position of bearing 5, nut 6 is outside equipped with the fastening slide block 7 of hold-doun nut 6 positions, and fastening slide block 7 is fixed on bearing support 8 by web member 9.Main shaft 1 front end is fixed with flange 2, and cutter 3 and cutter holder 4 are set on flange 2.In order to guarantee that main shaft 1 normally rotates, running fit between main shaft 1 and bearing 5, nut 6, fastening slide block 7.During cutting machine work, flange 2 and cutter 3, tool fastening device 4 and main shaft 1 form rotating part and jointly rotate, and bearing 5, nut 6, fastening slide block 7 and bearing support 8 are motionless, heat-eliminating medium 10 is washed on cutter 3 with certain flow, and cutter 3 is carried out to cooling and cleaning.
These cutting machine turning axle existing problems are, because cutter 3 with certain circular frequency along main shaft 1 axle center high speed rotating, when heat-eliminating medium 10 runs into the cutter 3 of high speed rotating, under the reactive force of centripetal force and 3 pairs of heat-eliminating mediums 10 of cutter, heat-eliminating medium 10 can be splashed on main shaft 1 with cutting chip, by the gap between main shaft 1 and bearing 5, enter in bearing 5, during main shaft 1 rotation, cutting chip plays the effect of grinding medium between bearing 5 and main shaft 1, bearing 5 and main shaft 1 are ground, when too much cutting chip enters bearing 5, the phenomenon (locking) that the easy appearance of main shaft 1 cannot be rotated, meanwhile, heat-eliminating medium 10 enters behind the gap of bearing 5 and main shaft 1 can corrosion bearing 5 and main shaft 1, has accelerated the damage of bearing 5 and main shaft 1, thereby has shortened the work-ing life of cutting machine, has increased production cost.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of cutting machine turning axle of long service life.
The technical scheme that the utility model technical solution problem adopts is: cutting machine turning axle, main shaft is engaged in bearing, described bearing is fixed on bearing support, nut and bearing thread fit, described nut is outside equipped with the fastening slide block of hold-doun nut position, and described fastening slide block is fixed on bearing support, and described front-end of spindle is fixed with flange, on described flange, by web member, be provided with gear cylinder, described gear cylinder is arranged between flange and fastening slide block.
Further, on described flange, cutter and cutter holder are set.
Further, running fit between described main shaft and bearing, nut, fastening slide block.
Further, described main shaft is step shaft.
Further, described fastening slide block is fixed on bearing support by web member.
Further, described web member is screw or bolt.
Further, described gear cylinder and flange are integrative-structures.
The beneficial effects of the utility model are: the utility model prevents that by increasing by one between the rotating part at cutting machine turning axle and stationary part heat-eliminating medium and cutting chip from entering the safety guard of bearing, during cutting, can well prevent that the chip after heat-eliminating medium and cutting from entering in main shaft, prevents its corrosion to main shaft and bearing.

Embodiment
Cutting machine turning axle of the present utility model is provided with gear cylinder 11 by web member 9 on flange 2, and gear cylinder 11 is arranged between flange 2 and fastening slide block 7, as Figure 4-Figure 6.Gear cylinder 11 covers up being exposed to outer part main shaft 1 between flange 2 and fastening slide block 7, to avoid entering of heat-eliminating medium 10.
Above-mentioned web member 9 can be screw, bolt etc., or directly adopts and be welded to connect.Above-mentioned flange 2 is enclosed within the front end of main shaft 1, and cutter 3 is enclosed within on flange 2.Bearing 5 is arranged on bearing support 8, and bearing 5 regulates its motion in the axial direction by nut 6, and nut 6 is fixed on bearing support 8 by fastening slide block 7 and web member 9, and assurance bearing 5 is fixed with bearing support 8.
When cutting machine moves, flange 2, cutter 3, gear cylinder 11 rotate jointly with main shaft 1, and bearing 5, fastening slide block 7 and bearing support 8 are motionless, and gear cylinder 11 can stop that heat-eliminating medium 10 and cutting chip are splashed in the gap between bearing 5 and main shaft 1 well.
Above-mentioned gear cylinder 11 and flange 2 can be also integrative-structures, as shown in Figure 6.
