Bar, two bolts are separately mounted under tailstock in the left and right counterbore of seat, and each bolt lower end is equipped with clamping press plate, and middle part is equipped with
Washer, washer are sequentially arranged with lower wedge, upper wedge, flange, the hydraulic cylinder left end by the threaded rod of external part with
The oblique iron phase in left side connects, and the cylinder body right end of hydraulic cylinder is connected by the oblique iron phase on bottom plate and screw rod and right side；The water
Square pushing up oil cylinder, ejector pin, brake iron, pressing plate by four groups of sides to clamping device forms, planar ends and the side top oil cylinder of the ejector pin
Piston rod is in contact, and sphere end and the brake iron of ejector pin connect, and the brake iron and pressing plate are separately mounted to the two of bed ways
Side.
The flange is equipped with stick and holding screw with the place of screwing at the top of bolt.
The upper wedge is equipped with angle coupling and lubricating oil pipe.
The hydraulic cylinder left and right ends are respectively arranged with nut with lower wedge junction.
The lower wedge lower end is connect with washer contacts, and upper end is fitted closely with flange, and flange is threadedly attached in spiral shell
Bolt top.
The utility model has the beneficial effects that：
Compared with the prior art, the utility model is by adopting the above-described technical solution, therefore big with clamping force, folder
Tightly, loosening operation is convenient, saves strength and time, can ensure Workpiece Machining Accuracy and suface processing quality to a certain extent
The advantages that.
Description of the drawings

Fig. 2 is the revolved sectional view along A-A in Fig. 1.
Fig. 3 be in Fig. 1 along X to revolved view.
Specific implementation mode
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Such as Fig. 1, shown in 2,3, a kind of CNC heavy-duty horizontal lathe tailstock clamp system, including bolt 1, clamping press plate 2, spiral shell
Mother 3, washer 4, lower wedge 5, upper wedge 6, stick 7, holding screw 8, flange 9, angle coupling 10, lubricating oil pipe 11, hydraulic cylinder 12,
Bottom plate 13, screw rod 14, ejector pin 16, side top oil cylinder 17, screw fastening shaft end baffle ring 18, brake iron 19, pressing plate 18, pressing plate 20, plate 21,
Limited block 22.
Vertical direction clamping device is made of four groups of oblique-wedge clamping systems, and washer 4 is mounted under tailstock in the counterbore of seat, under
Wedge 5 is mounted on washer 4, upper wedge 6 and the 5 mating installation of lower wedge, forms tapered wedges, and tapered wedges upper surface is tight with flange 9
Closely connected conjunction, flange 9, which is connected through a screw thread, is screwed in 1 top of bolt.Flange 9 is equipped with stick 7 and holding screw with the 1 top place of screwing of bolt
8.Upper wedge 6 is equipped with angle coupling 10 and lubricating oil pipe 11.
12 left end of hydraulic cylinder is connected by the threaded rod of external part with lower wedge 5, and 12 right end of hydraulic cylinder passes through with bottom plate 13
It is bolted, bottom plate 13 is connect with lower wedge 5 by screw rod 14.On the threaded rod and screw rod 14 of 12 left end external part of hydraulic cylinder
