Compare with internal grinder, this building-block machine per hour processing capacity of connecting rod is about 3 times of internal grinder, has improved the working (machining) efficiency of connecting rod greatly, has reduced production cost; Simultaneously, the hole of this building-block machine processing is also higher with respect to interior mill stability, has eliminated the hidden danger of grinding crack after the Tool in Cutting, the safe in utilization and life-span of having improved connecting rod greatly.
Description of drawings:
Fig. 1 is the whole structural scheme of mechanism of the utility model;
Fig. 2 is the utility model main spindle box structural representation;
Fig. 3 is the utility model clamp structure schematic diagram.
As shown in Figure 1 and Figure 2, the building-block machine of present embodiment is a horizontal single face list station connecting rod right boring hole special plane.Lathe base 1 adopts monoblock cast, has rigidity and precision stability preferably.Main spindle box 3 and motor 4 are fixed on the SEHY400/400 hydraulic pressure moving platform 2, be provided with the main shaft of fixing by bearing 30,31 and back-up ring 32 33 in the main spindle box 3, offer the boring bar locating hole that is connected with boring bar 5 in one end of main shaft, the other end is connected with synchronizing wheel 44 by flat key 41.This synchronizing wheel is connected by belt 42 with synchronizing wheel 43 on motor 4 output shafts.Belt adopts Circular Arc Profile Synchronous Belt.
Anchor clamps 6 constitute (see figure 3) by pedestal, oil cylinder, paw, paw locating piece, locating bar and location pile crown, are fixed on the base 1 of a corresponding side with boring head.The lower, transverse of pedestal 61 has through hole, paw locating piece 81 is installed in this through hole, one end of paw locating piece and the lower cover of oil cylinder 67 are affixed by screw 83, be provided with hollow piston bar 68 in the oil cylinder, one end of screw rod 63 is by bolt 62 location, the other end is inserted by oil cylinder loam cake 65, passes hollow piston bar and oil cylinder lower cover, is connected with the head that inserts R shape paw 82 within it from the paw locating piece other end.The upper lateral of pedestal 61 is provided with the through hole that screw 73 is installed, and the both sides of this through hole are installed an adjustable plate 71,77 respectively, are linked together tightly by the adjustable plate and the screw 73 of screw 72 with these both sides.Screw be threaded by the vertically arranged screw rod 75 in pedestal top.The pedestal top is fixed with adjustable plate 74 by screw 76.With installing connecting rods location pile crown 78 on the adjustable plate 77 of paw homonymy, by adjusting screw(rod) 75, can realize the upper and lower displacement of connecting rod pile crown, to adapt to the needs of process multiple connecting rod, the utilization rate of expansion anchor clamps.
