Abstract
Title of the present utility model is grinder wheel static balance adjusting device, relates to bearing and repairs in grinding process, grinding wheel balance device on centerless grinder used.It mainly solves existing grinding machine grinding wheel static balancing adjusting device, in the left end groove of grinding wheel flange body, balance weight is housed, and the static balance of emery wheel needs just can carry out through more than twice or twice, uses inconvenience, the problem that the adjustment trouble time is long.The main shaft that the utility model comprises disc flange body and is closely connected in the conical axis hole of disc flange body, be connected to the blind flange on disc flange body, and threaded engagement is connected to the flange hold-down nut of spindle nose, it is characterized in that: flange hold-down nut is a convex shape, in the center screw of flange hold-down nut and spindle nose, be connected with adjustment screw.Utility model structure is simple, and cost is low, and operating efficiency is high, and Adjustment precision is 3 times of prior art, and the surface roughness that grinding goes out can improve 1 to 2 grade.
Description
Technical field
The utility model relates to the device of grinding machine grinding wheel static balancing adjustment, and what be specifically related to is that bearing is repaired in grinding process, the grinding wheel balance device on centerless grinder used.
Background technology
Existing grinding machine grinding wheel static balancing adjusting device as shown in Figure 1, the method of adjustment wheel balance is, grinding wheel flange body and main shaft pass through taper fit, flange clamp nut and main shaft right-hand member threaded engagement screw, emery wheel right-hand member blind flange is fixed on grinding wheel flange body by hold-down screw, when needing to install emery wheel additional, according to the thickness installing emery wheel, adjustment hold-down screw and flange clamp nut.In the left end groove of grinding wheel flange body, balance weight is housed, during adjustment grinding wheel static balancing, allow its balance weight Free-rolling adjust the block number of the balance on grinding wheel chuck, adjusted towards eminence by balance on grinding wheel chuck, the static balance of such emery wheel needs just can carry out through more than twice or twice.Carry out in grinding process at use grinding machine, the balance of emery wheel is very important, especially in high-speed grinding process, the balance of emery wheel directly has influence on machining accuracy and surface roughness, there is balance quality difference in grinding wheel static balancing method and the wheel balancing device of above traditional grinding machine, use inconvenience, the defects such as the adjustment trouble time is long.
Summary of the invention
The purpose of this utility model is for above-mentioned deficiency, and the one provided is easy to use, and machining accuracy is high, regulation time is short, without the need to the grinder wheel static balance adjusting device of counterweight.
Technical solution of the present utility model is: the main shaft that grinding wheel balance device comprises disc flange body and is closely connected in the conical axis hole of disc flange body, be connected to the blind flange on disc flange body, and threaded engagement is connected to the flange hold-down nut of spindle nose, it is characterized in that: flange hold-down nut is a convex shape, in the center screw of flange hold-down nut and spindle nose, be connected with adjustment screw.
The side plane of the flange hold-down nut described in technical solution of the present utility model and adjustment screw exceeds the outerplanar of blind flange.
The utility model is after the screw of mounting flange lid and the knockout screw of spindle nose fix, adjust emery wheel again, when emery wheel rotation has high point, by the amount of unbalance part of diamond cutter adjustment emery wheel, the static balance of emery wheel can be realized, adjustment once carries out trimming wheel, and can complete statically balanced all processes, grinding wheel flange body left end does not need to add balancing weight; The utility model is compared with prior art balancing method, and structure is simple, and cost is low, operating efficiency is high, and Adjustment precision is 3 times of prior art, with a grinding machine, same stock removal carries out grinding to same workpiece, and the surface roughness that grinding goes out can improve 1 to 2 grade; The emery wheel of the utility model static balance method adjustment is used to carry out grinding, not only favourable to raising crudy, and pressure, frictional force and internal stress when can reduce machine tool running, also can obtain beneficial effect to the raising many index such as mechanical efficiency and service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art.
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 2, the utility model is made up of main shaft 1 and disc flange body 2, blind flange 3, hold-down screw 4, adjustment screw 5, flange hold-down nut 6, the outer shape of main shaft 1 is identical with the shape and size of the axis hole of disc flange body 2 with size, and the taper shape of main shaft 1 is identical with disc flange body 2 hole tapering, and main shaft 1 is closely connected in the conical axis hole of disc flange body 2, flange hold-down nut 6 threaded engagement is connected to the end of main shaft 1, blind flange 3 is fixed on grinding wheel flange body 2 by hold-down screw 4, flange hold-down nut 6 is in a convex shape, adjustment screw 5 is connected with in the center screw of this convex shape flange hold-down nut 6 and main shaft 1 end, adjustment screw 5 is passed from flange hold-down nut 6 center screw, be fixed in the center screw of main shaft 1 end, the side plane of flange hold-down nut 6 and adjustment screw 5 exceeds the outerplanar of blind flange 3, after hold-down screw 4 and adjustment screw 5 are fixed, then emery wheel 7 is contained on grinding wheel flange body 2, according to the thickness installing emery wheel 7, adjustment hold-down screw 4 and adjustment screw 5, starter motor, main shaft 1 drives emery wheel 7 to rotate, all components is all on emery wheel 7 rotation centerline, after flange hold-down nut 6 and main shaft 1 screw thread screw, the axial displacement of main shaft 1 is limited, after adjustment screw 5 and main shaft 1 screw thread screw, the axial displacement of flange hold-down nut 6 and blind flange 3 is all limited, realize emery wheel 7 to be fixed, when now emery wheel 7 rotates, only its peak need be repaiied by diamond cutter mill, emery wheel 7 just can realize static balance, namely when emery wheel 7 rotation has high point, by the amount of unbalance part of diamond cutter adjustment emery wheel 7, once can realize the static-unbalance adjusting emery wheel 7.
