Abstract
The utility model discloses a high efficiency automatic clamp apparatus to overcome the clamping difficulty of the present lathe clamp apparatuses when undertaking the lathe work of the excircle and the end-face of the big disk type component, which comprises a rotary cylinder, a cylinder rod connected with the rotary cylinder, a clamp apparatus body, a disk, a push bar, an expansion sheathing, and a gland, wherein the rotary cylinder is arranged on the back of the main spindle of the lathe main spindle box, a clamp apparatus is positioned in the taper hole on the front of main spindle, the cylinder rod is connected with a lather liquid pressure system, a disk is arranged in the clamp apparatus, three push bars are uniformly arranged on the disk, the expand sheathing is arranged on the front end face of the clamp apparatus, and the gland is arranged on the front end of the clamp apparatus. The utility model uses the elastic expansion sheathing to expand and clamp work piece from bore, simultaneously employing the automatic clamp of the liquid pressure system to freely clamp or loose the big disk type component, thereby reducing the labor intensity of the operator, and increasing the productive efficiency.
Description
Technical field
The utility model relates to a kind of hydraulic chucks, on a kind of specifically numerically controlled lathe or engine lathe that is mainly used in field of machining, to the end face of processing macropore disk-like accessory and the automatic jig of cylindrical turning processing.
Background technology
At present, on numerically controlled lathe or engine lathe, the chucking of workpiece and unclamp all be the manual operations, labor strength is big, inconvenient operation, productivity ratio is low.
The utility model content
The purpose of this utility model provides a kind of efficient jig automatically, with solve that existing lathe jig exists to macropore disk-like accessory cylindrical and facing processing the time the be installed problem of difficulty.
The utility model comprises angling cylinder, the piston rod that links to each other with angling cylinder, fixture body, disk, push rod, ringfeder, gland, angling cylinder is contained in the rear end of Lathe Spindle Box main shaft, fixture body is positioned in the front-end of spindle taper hole, and piston rod and machine tool hydraulic system link; Be provided with disk in fixture body, be evenly equipped with three push rods on disk, the fixture body front end face is provided with ringfeder, and the fixture body front end is equipped with gland.
The utility model adopt elastic expansion-sleeve from endoporus with the workpiece swelling, reach the purpose of chucking, adopt hydraulic system to tighten automatically simultaneously, can realize the chucking of macropore disk-like accessory at any time easily and unclamp, reduce operator's labour intensity, improved production efficiency.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model comprises angling cylinder 1, the piston rod 2 that links to each other with angling cylinder 1, fixture body 3, disk 4, push rod 8, ringfeder 7, gland 6, angling cylinder 1 is contained in the rear end of Lathe Spindle Box 5 main shafts, fixture body 3 is positioned in the front-end of spindle taper hole, and piston rod 2 links with machine tool hydraulic system; Be provided with disk 4 in fixture body 3, be evenly equipped with three push rods 8 on disk 4, fixture body 3 front end faces are provided with ringfeder 7 (for elastic expansion-sleeve), and the endoporus of ringfeder 7 is 1: 20 conical surface, this conical surface self-locking.The conical surface 9 of fixture body 3 is 1: 20 conical surface.Fixture body 3 front ends are equipped with gland 6.
Add man-hour, workpiece 10 is contained on the ringfeder 7, elastic expansion-sleeve 7 from the endoporus of workpiece 10 with workpiece 10 swellings, during work, angling cylinder 1 oil-feed, piston rod 2 is moved to the left, gland 6 forces ringfeder 7 spreadings, workpiece 10 from the endoporus tensioner, at this moment just can be carried out turning processing, but processing excircles, end face and forming surface.After the completion of processing, angling cylinder 1 reverse oil-feed, piston rod 2 moves right, and three push rods 8 that are distributed on the disk 4 are pushed workpiece 10 open from the conical surface (this conical surface self-locking) of fixture body 3, realize unclamping of workpiece 10, and workpiece just can be taken down from fixture body 3.
