Description
Technical field
The present invention relates to the bent axle anchor clamps of turning or grinding crank-shaft link neck, specifically a kind of replaceable eccentric disc is transferred the crankshaft eccentric anchor clamps of eccentric throw.
Background technology
We know; Bent axle is one of the strength member of load, transferring power that withstands shocks in the engine; Its structure and stressed complicacy; Live load is big; In order to guarantee the stationarity of engine operation, the connecting rod neck phase angle of different bent axles is distributed with 120 °, 60 °, 72 °, 90 °, 180 ° or more.And requirement on machining accuracy is all very high.Turning or grinding crank-shaft link neck have all adopted eccentric fixture.For small-sized bent axle is to adjust eccentric throw with leading screw and nut structure; But because cun required precision of crankshaft eccentric carpenters square is higher; In order to satisfy this requirement; Adopted fixing eccentric packing mostly for large-scale bent axle; Eccentric packing one end is installed on the machine tool chief axis; The other end links to each other with clamp body or clamp base through rectangular rail, and rotational lead screw drives clamp body through nut or clamp base moves with respect to eccentric packing, adjusts the desired eccentric throw of different bent axles.Not only time-consuming, also be difficult to guarantee required precision.Because bent axle is wide in variety, eccentric throw differs, and makes every sleeve clamp all need an eccentric packing, causes the anchor clamps manufacturing cost high.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes above-mentioned prior art, provides a kind of rational in infrastructure, installs simply, and cost is low, and is safe and reliable, and the replaceable eccentric disc that is suitable for the various large-scale crank-shaft link necks of turning is transferred the crankshaft eccentric anchor clamps of eccentric throw.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of crankshaft eccentric anchor clamps; It comprises spindle flange dish, packing, eccentric disc, clamp body, bent axle clamp mechanism; It is characterized in that: the said packing outside is provided with boss; Be fixedly mounted in the spindle flange dish hole through screw; The packing inboard is provided with the eccentric disc installing hole; The eccentric disc that has eccentric shaft is fixed on the packing through sunk screw, and the clamp body endoporus is installed on the eccentric shaft through bearing; Also be provided with several T-slot holes on the packing, clamp body is provided with the through hole corresponding with the T-slot hole, cooperates through T shape screw and nut to compress, and clamp body is fixed on the packing; The anterior bent axle clamp mechanism of installing of clamp body.
Bent axle clamp mechanism of the present invention is provided with lower slips, gland, upper slips; Lower slips and upper slips are fixed on clamp body and the gland through screw respectively; The clamp body front part sides is provided with groove; Gland one end is provided with boss; With clamp body one side groove fit, and link to each other with clamp body with hinge pin; Connect a homalocephalus nut through bearing pin in the clamp body opposite side groove, the gland other end is provided with the U-shaped mouth, and the U-shaped mouth penetrates the homalocephalus nut, compresses connection with clamp nut.
The present invention is owing to be provided with an eccentric disc installing hole in the packing inboard, and eccentric disc is fixed on the packing through sunk screw, can be very little according to different crankshaft eccentric carpenters squares, change eccentric disc, and transfer eccentric throw.Against existing technologies, the present invention is rational in infrastructure, installs simply, and operation is fast and saving time, and production efficiency is high, and is safe and reliable, and it is simple that eccentric disc is changed, and no longer need change complex structure, huge packing.The present invention is applicable to the bent axle anchor clamps of making turning or the various large-scale crank-shaft link necks of grinding.Left and right anchor clamps are used to clamp main bearing journal, turning or grinding crank-shaft link neck.
