The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further described in detail:
The balance weight mechanism front view that Fig. 1 is high-frequency reciprocating moving component of the present invention, Fig. 2 is the partial left side view in Fig. 1.
In Fig. 1,2, the balance weight mechanism of high-frequency reciprocating moving component of the present invention, comprise weight mass piece 1, lifting bolt 2, steel wire rope 3, pulley bracket 4, pulley 5, nut 6, pulley mandrel 7, motion slide unit 8, machine pillar 9; Its annexation is that described pulley bracket 4 is arranged on machine pillar 9 tops by screw; Be provided with positioning step on pulley mandrel 7, pulley 5 is arranged on pulley mandrel 7 and by nut 6 and is fixed on pulley bracket 4; Steel wire rope 3 is walked around each pulley 5 be arranged on pulley bracket 4, and two ends respectively arrange a lifting bolt 2 and are connected to the upper center of motion slide unit 8 and the upper center of weight mass piece 1.
Described weight mass piece 1 equates with the quality of motion slide unit 8.
Described lifting bolt is provided with two, and lifting bolt 2 is one of them.
Described pulley bracket 4 is semicircle.
Described pulley is provided with 12, and pulley 5 is one of them, and 12 pulleys distribute symmetrically along pulley bracket 4.
Described pulley mandrel is provided with 12, and pulley mandrel 7 is one of them, and pulley mandrel and pulley be corresponding matching one by one.
Described nut is provided with 12, and nut 6 is one of them, pulley mandrel of each nut check.
Described steel wire rope 3 provides high rigidity, guarantees the motion uniformity of weight mass piece 1 and motion slide unit 8.Adopt semicircular pulley bracket 4 and a plurality of pulley 5 to reduce steel wire rope 3 resistances of motion, and keep the radius of curvature of steel wire rope 3 larger, thereby reduce its bending stress, thereby extended the service life of steel wire rope 3.Balance weight mechanism can be saved the Z-direction driving force, provides protection when outage simultaneously, prevents that moving slide block 8 landings from damaging lathe and part to be processed.
