Abstract
The utility model relates to a grinding wheel balancer which comprises a supporting frame and at least four bearings. The supporting frame comprises a bottom plate, parallel side walls and grooves, the bottom surface of the bottom plate is a horizontal plane, the side walls are perpendicular to the bottom plate and arranged on two sides of the bottom plate, the grooves are embedded into the tops of the side walls respectively, the bearings are used for carrying grinding wheel fixing shafts and symmetrically and rotatably mounted in the grooves in the tops of the side walls, and the distance between the bearings on the same side wall is shorter than the diameter of the corresponding fixing shaft. The rotatable bearings are symmetrically mounted on the side walls of the supporting frame and placed in the grooves, on one hand, a plane formed by shaft axes of the bearings is parallel to the horizontal plane, the balancer does not need to be corrected before use, on the other hand, the friction force among the bearings and the grinding wheel fixing shafts is small, and static balance conditions of grinding wheels can be accurately and rapidly tested.
Description
Technical field
The utility model relates to balace weight, is specifically related to a kind of balace weight for grinding wheel static balancing.
Background technique
General diameter is greater than the emery wheel of 125 millimeters all will carry out balance, and the center of gravity of emery wheel is overlapped with its spin axis.Unbalanced emery wheel can produce vibration in the time of High Rotation Speed, affects quality of processing and machine tool accuracy, also can cause machine damage and emery wheel cracked when serious.Cause unbalanced former tired be mainly emery wheel each several part Density inhomogeneity, the asymmetric and setting-up eccentricities of geometrical shape etc. therefore all will carry out balance before emery wheel is installed.The balance of emery wheel has two kinds of static balancing and dynamic balancing.Generally, only static balancing need be done, but when high speed grinding (speed is greater than 50m/s), dynamic balancing must be carried out.Wheel balance device is the annex that grinding machine must be equipped with, can static balancing emery wheel with it, to reach the object of correct use emery wheel, add leveling instrument and can also detect the static balancing of precision workpiece.When balance, emery wheel is contained in balance axle, then the emery wheel that installs axle is kept flat on the balance guide rail of wheel balance support, emery wheel can swing back and forth, and stops until swinging.The emery wheel of balance can be at an arbitrary position transfixions all, if wheel unbalance, below its heavier part always forwards to, the at this moment position of Moveable balance block or add equilibrium block in emery wheel both sides, makes it reach balance.Existing wheel balance device will first be corrected balace weight, complicated operation before each use.
Summary of the invention
The utility model object be provide in order to overcome the deficiencies in the prior art a kind of simple in structure, can accurately correct and wheel balance device easy and simple to handle emery wheel.
For achieving the above object, the technical solution adopted in the utility model is: a kind of wheel balance device, and it comprises:
Supporting frame, support frame as described above comprise bottom surface be horizontal plane base plate, be parallel to each other and be located at the sidewall of its both sides, be embedded at respectively the groove of top side wall perpendicular to base plate;
Bearing, for carrying on a shoulder pole the stationary axle of establishing emery wheel, described bearing is at least four, symmetrical and be rotatably installed on top side wall, and is located in groove;
Distance between described same sidewall upper bearing (metal) is less than the diameter of stationary axle.
Optimally, the radius that defines described stationary axle is R, and the radius of bearing is r, and the distance between described same sidewall upper bearing (metal) is less than 2(
).
Optimally, described groove is two.
Because technique scheme is used, the utility model compared with prior art has following advantages: the utility model wheel balance device, rotating bearing is installed and is placed in groove by symmetrical on supporting frame sidewall, on the one hand the plane that the shaft axis of bearing forms is paralleled with horizontal plane, thereby do not need to correct before use balace weight, frictional force between bearing and emery wheel stationary axle is little on the other hand, can accurately and fast test the static balancing situation of emery wheel.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the utility model wheel balance device;
Accompanying drawing 2 is the left view of accompanying drawing 1;
Wherein, 1, supporting frame; 11, base plate; 12, sidewall; 13, groove; 2, bearing; 3, emery wheel; 31, stationary axle.
Embodiment
Below in conjunction with accompanying drawing, the utility model preferred embodiment is elaborated:
Wheel balance device as shown in Fig. 1 to 2, mainly comprises supporting frame 1 and bearing 2.
Wherein, supporting frame 1 comprise bottom surface be horizontal plane base plate 11, be located at base plate 11 both sides sidewall 12, be embedded at the groove 13 at sidewall 12 tops; Sidewall 12 is two, is parallel to each other and perpendicular to base plate 11; Bearing 2 is rotatably installed on sidewall 12 tops and is located in groove 13.Bearing 2 quantity on two side 12 equate, every side has two bearings 2 at least, and the distance of 2 of same sidewall 12 upper bearing (metal)s is less than the diameter of stationary axle 31, the stationary axle 31 of emery wheel 3 central authorities can be carried on a shoulder pole and be located between bearing 2; Bearing 2 on two side 12 is symmetrical arranged the plane that the shaft axis of bearing 2 forms is paralleled with horizontal plane.Because the frictional force between the stationary axle 31 of bearing 2 and emery wheel 3 is little, emery wheel 3 loads are located at the static balancing situation that just can accurately and fast test emery wheel between bearing 2, do not need to correct balace weight before use.
In the present embodiment, the radius of stationary axle 31 is R, and the radius of bearing 2 is r, and the distance of 2 of same sidewall 12 upper bearing (metal)s should be less than 2(
), can make like this stationary axle 31 be positioned at the top of sidewall 12 and not contact with it, thereby further reduce the frictional force of bearing 2 and stationary axle 31.Groove 13 is two, is located at respectively the top of two sidewalls 12, and simple in structure, minimizing material consumption, reduces costs.
Above-described embodiment is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present utility model and implement according to this; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
