Description
Technical field
The utility model relates to a kind of positioning tool, relates in particular to a kind of for processing the positioning tool in belt pulley balance correction hole.
Background technology
As shown in Figure 1-2, belt pulley is provided with dynamic balance calibration hole 13 to existing belt sheave structure, and the angle of be separated by two dynamic balance calibration hole circle hearts and belt pulley endoporus 14 is 6 degree.At present, dynamic balance calibration hole mainly forms by artificial, due in process entirely with personal experience, the dynamic balance calibration pore size distribution that causes processing rear belt pulley is uneven, not of uniform size, also easily causes waste product.
Summary of the invention
In order to overcome the above-mentioned deficiency of prior art, the purpose of this utility model be to provide a kind of simple in structure, easy and simple to handle, machining accuracy is high for processing the positioning tool in belt pulley dynamic balance calibration hole.
For achieving the above object, the technical solution of the utility model is:
A kind of for processing the positioning tool in belt pulley dynamic balance calibration hole, it comprises a round turntable, one locating shaft, one spring, one ball ball and a rotary base, described locating shaft is fixed on rotary base by a plane bearing, the center of described rotating disk is provided with a circular hole, described circular hole passes locating shaft and by a bearing, rotating disk is fixed on locating shaft, on described locating shaft, be also provided with an opening pad and a nut, described rotating disk is provided with a drill bit correction hole, the disk lower surface corresponding with the described drill bit correction hole spherical locating slot of a circle of evenly arranging, described ball ball is fixed on described spring, described spring is arranged on rotary base by an adjustment screw, it is corresponding with described spherical locating slot that the installation site of spring should meet the ball ball making on spring.
Uniform 60 the spherical locating slots of arranging of lower surface of described round turntable.
Adopt such scheme, the utlity model has following usefulness:
By using positioning tool of the present utility model, effectively the concentricity of distance and workpiece and endoporus between control hole and hole, there will not be hole and edge break phenomenon, causes waste product, has improved product quality and production efficiency.
Operation:
Below in conjunction with accompanying drawing and body embodiment thereof, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing belt pulley;
Fig. 2 is the A-A direction schematic diagram of Fig. 1;
Fig. 3 is structural representation of the present utility model;
Fig. 4 is the top view of Fig. 3.
The specific embodiment
As shown in Figure 3-4 a kind of for processing the positioning tool in belt pulley dynamic balance calibration hole, it comprises a round turntable 6, one locating shaft 1, one spring 9, one ball ball 8 and a rotary base 10, described locating shaft 1 is fixed on rotary base 10 by a plane bearing 12, the center of described rotating disk 6 is provided with a circular hole, described circular hole passes locating shaft 1 and by a bearing 4, rotating disk 6 is fixed on locating shaft 1, on described locating shaft 1, be also provided with an opening pad 3 and a nut 2, described rotating disk 6 is provided with a drill bit correction hole 5, rotating disk 6 lower surfaces corresponding with the described drill bit correction hole 5 spherical locating slot 7 of a circle of evenly arranging, the number of described spherical locating slot 7 is 60, described ball ball 8 is fixed on described spring 9, described spring 9 is arranged on rotary base 10 by an adjustment screw 11, it is corresponding with described spherical locating slot 7 that the installation site of spring 9 should meet the ball ball 8 making on spring 9.
When belt pulley carries out dynamic balance calibration hole drilling, first positioning tool of the present utility model is arranged on Drilling machines bench, and drill bit is aimed to drill bit correction hole; Then belt pulley to be processed is placed on positioning tool of the present utility model, and endoporus aligning locating shaft, put opening pad, then nut check; Movable roundabout, spherical locating slot and the ball ball of disk lower surface match, and enter first boring position, and drill bit is holed downwards, complete after first boring, promote rotating disk, ball ball leaves first spherical locating slot, enters second spherical locating slot, now, rotating disk goes to second boring position, holes for the second time, and so forth
The utility model evenly arranges 60 spherical locating slots at the lower surface of rotating disk, thereby guarantees the concentricity of distance and workpiece and endoporus between Kong Yukong, there will not be hole and edge break phenomenon, causes waste product, has improved product quality and production efficiency.
