Summary of the invention
The purpose of this utility model is to provide the eccentric cam of screw tap Special Turbine Grinding Machine, the eccentric cam of screw tap Special Turbine Grinding Machine is a vitals of Special Turbine Grinding Machine, design correct, rational in infrastructure, can make Special Turbine Grinding Machine normal operation, regular at work, thereby guarantee Special Turbine Grinding Machine working stability, keen edge, the precision of the screw tap that relief grinding goes out are high, relief grinding puts in place, have overcome the eccentric cam design fault, unreasonable structure of common Special Turbine Grinding Machine and the relief grinding dislocation that causes, the defect such as precision is not high, the knife edge is turned.
Technological scheme: the eccentric cam of screw tap Special Turbine Grinding Machine, comprise cam and hole, it is characterized in that cam is a cylindrical slug, the diameter of the cylindrical of cam is 27.5 ㎜, forward and backward width is 15 ㎜; At the front disc of cam and the round edge angle of rear disc, be cut into separately the chamfering of 45 °, chamfering distance is 1 ㎜; In the drilled in middle of the front disc of cam a circular through hole, circular through hole bores rear disc from the disc of cam always; The diameter of circular through hole is 10 ㎜; Among the front disc of cam and above circular through hole, bored again the through hole of a cuboid; The through hole of cuboid bores rear disc from the disc of cam always; The left and right width of the through hole of cuboid is 4 ㎜; The through hole of cuboid and circular through hole interconnect; The cylindrical of cam has the cylindrical center of circle, and the center of circle of circular through hole outside the vertical lower, the distance that departs from the cylindrical center of circle of the round heart be 2 ㎜, form eccentric cam; The center of circle of the cylindrical center of circle of cam and circular through hole can form the line in two centers of circle, and the line in two centers of circle is lines of Vertical direction; The vertical center line of the left and right direction of the through hole of cuboid is divided the left and right width of the through hole of cuboid equally, cam flat is divided into left and right each half block cam simultaneously, and left half block cam and right half block cam are symmetrical mutually; That is to say: the vertical center line of the left and right direction of the through hole of cuboid overlaps with the vertical center line of the left and right direction of cam; The vertical center line of the left and right direction of the through hole of cuboid overlaps with the line in above-mentioned two centers of circle again; The through hole of cuboid interconnects into eccentric cam through hole with circular through hole, and the upper and lower total height of this eccentric cam through hole is 12 ㎜; Cam can be made of materials such as stainless steel or aluminum alloys.
The utility model has the advantages that: the eccentric cam that screw tap Special Turbine Grinding Machine is provided, the eccentric cam of screw tap Special Turbine Grinding Machine is a vitals of Special Turbine Grinding Machine, design correct, rational in infrastructure, can make Special Turbine Grinding Machine normal operation, regular at work, thereby guarantee Special Turbine Grinding Machine working stability, keen edge, the precision of the screw tap that relief grinding goes out are high, relief grinding puts in place, have overcome the eccentric cam design fault, unreasonable structure of common Special Turbine Grinding Machine and the relief grinding dislocation that causes, the defect such as precision is not high, the knife edge is turned; Can meet enterprise's Production requirement.

Embodiment
Below in conjunction with accompanying drawing in detail the utility model is described in detail:
The eccentric cam of screw tap Special Turbine Grinding Machine, comprises cam and hole, it is characterized in that cam 1 is a cylindrical slug, and the diameter of the cylindrical of cam 1 is 27.5 ㎜, and forward and backward width is 15 ㎜; Front disc 2 at cam 1 is cut into the chamfering 5 of 45 ° separately with the round edge angle of rear disc, and chamfering distance is 1 ㎜; In the drilled in middle of the front disc 2 of cam 1 a circular through hole 3, circular through hole 3 bores thoroughly to rear disc from the disc 2 of cam 1 always; The diameter of circular through hole 3 is 10 ㎜; Among the front disc 2 of cam 1 and above circular through hole 3, bored again the through hole 4 of a cuboid; The through hole 4 of cuboid bores thoroughly to rear disc from the disc 2 of cam 1 always; The left and right width of the through hole 4 of cuboid is 4 ㎜; The through hole 4 of cuboid interconnects with circular through hole 3; The cylindrical of cam 1 has the cylindrical center of circle, and the center of circle of circular through hole 3 outside the vertical lower, the distance that departs from the cylindrical center of circle of the round heart be 2 ㎜, form eccentric cam; The center of circle of the cylindrical center of circle of cam 1 and circular through hole 3 can form the line in two centers of circle, and the line in two centers of circle is lines of Vertical direction; The vertical center line of the left and right direction of the through hole 4 of cuboid is divided the left and right width of the through hole of cuboid 4 equally, cam 1 is divided equally for left and right each half block cam simultaneously, and left half block cam and right half block cam are symmetrical mutually; That is to say: the vertical center line of the left and right direction of the through hole 4 of cuboid overlaps with the vertical center line of the left and right direction of cam 1; The vertical center line of the left and right direction of the through hole 4 of cuboid overlaps with the line in above-mentioned two centers of circle again; The through hole 4 of cuboid interconnects into eccentric cam through hole with circular through hole 3, and the upper and lower total height of this eccentric cam through hole is 12 ㎜; Cam 1 use stainless steel material is made.
