Abstract
The utility model relates to a mechanical power chucking device, consisting of a jaw, a ring flange, a coupling flat key, a bolt, a screw rod, a worm wheel, a worm, an axial adjusting pad and a jaw base. The jaw is connected with a chuck screw rod; the worm is fixed with the ring flange by the bolt; the lower part of the worm is provided with the axial adjusting pad; the worm drives the worm wheel; the worm wheel is connected with the screw rod by the coupling flat key and is fixedly arranged on a chuck body; and the jaw base is fixedly arranged on the chuck body. When the wrokpiece is chucked, the jaw base is moved near the workpiece according to the diameter of the workpiece; the worm is rotated clockwise with a special spanner; the worm drives the worm wheel; the worm wheel is connected with the screw rod by the coupling flat key to transfer force; and consequently, the mechanical power chucking of the workpiece is realized. Mechanical loosening is realized contrarily and the axial clearance of the worm is ensured by the axial adjusting pad. The chuck is provided with four mechanical power chucking devices. The workpiece can be chucked tightly and loosened conveniently and reliably; the labor is saved; the labor intension is reduced; and the production efficiency is improved.
Description
Technical field
The utility model relates to the gripping mechanism in the heavy-duty engine lathe chuck, particularly a kind of mechanical booster gripping mechanism that heavy horizontal lathe workpiece reinforcement is clamped and loosens.
Background technology
At present, on heavy horizontal lathe, adopt feed screw nut's form to move claw to the gripping mechanism of workpiece great majority and carry out brute force and tighten, this chucking mode has not only increased the non-cutting time of lathe, increase working strength of workers again, and influenced labor productivity.It is reported, current only have the minority heavy horizontal lathe to adopt the imported mechanical clamping screw to be fixed on the master jaw to tighten, this kind chucking mode in actual use at first will according to the diameter of workpiece with master jaw move to workpiece near after carry out mechanical booster with the mechanical grip screw again and tighten; Owing to adopt the mechanical grip screw to need import, strengthened the funds spending of introducing equipment annex, thereby the cost of lathe is sharply increased, the cost performance of lathe descends.
Summary of the invention
The purpose of this utility model is to improve at the deficiencies in the prior art, and design provides a kind of mechanical booster gripping mechanism that is now changed into the Worm and Worm Gear Driving form by original feed screw nut's type of belt drive; This device can be realized fast moving and forward and reverse reinforcement chucking, can shorten the non-cutting time of lathe, can reduce working strength of workers, can enhance productivity.
The technical scheme that realizes the technical solution problem is: the mechanical booster gripping mechanism comprises claw (1), and ring flange (2) connects flat key (3), screw (4), and screw mandrel (5), worm gear (6), worm screw (7), axial adjusting pad (8), master jaw (9) is formed; Described claw (1) Connection Card parcel bar (5), worm screw (7) is fixing by screw (4) and ring flange (2), in the bottom of worm screw (7) axial adjusting pad (8) is housed, worm screw (7) worm gear (6) relatively carries out transmission, worm gear (6) is connected with screw mandrel (5) by connection flat key (3) and is packed on the chuck body, and master jaw (9) is fixed on the chuck body.
The end play of described worm screw (7) is adjusted by axial adjusting pad (8).
The transmission of described worm gear (6) and worm screw (7) thereof can realize self-locking.
Described four mechanical booster gripping mechanisms are installed on chuck.
The utility model compared with prior art has following advantage:
1, simple in structure, reasonable in design, easy to use;
2, four mechanical booster gripping mechanisms have been installed on chuck, can have been tightened and unclamp workpiece convenient, fast, laborsaving, reliably;
3, reduce cost, reduced working strength of workers, improved labor productivity.
Description of drawings
Fig. 1 is the utility model mechanical booster gripping mechanism structure connection diagram
Among the figure, 1-claw, 2-ring flange, 3-connect flat key, 4-screw, 5-screw mandrel, 6-worm gear, 7-worm screw, the axial adjusting pad of 8-, 9-master jaw;
The specific embodiment
Below in conjunction with the drawings and specific embodiments this technical scheme is further described
With reference to Fig. 1, the mechanical booster gripping mechanism is made up of claw 1, ring flange 2, connection flat key 3, screw 4, screw mandrel 5, worm gear 6, worm screw 7, axial adjusting pad 8, master jaw 9; Claw 1 Connection Card parcel bar 5, worm screw 7 is fixing with ring flange 2 by screw 4, and axial adjusting pad 8 is housed in the bottom of worm screw 7, and worm screw 7 relative worm gears 6 carry out transmission, worm gear 6 is connected with screw mandrel 5 by connection flat key 3 and is packed on the chuck body, and master jaw 9 is fixed on the chuck body.The end play of worm screw 7 is adjusted by axial adjusting pad 8; The transmission of worm gear 6 and worm screw 7 thereof can realize self-locking.
Its course of work is: when the chucking workpiece, according to the big I of diameter of work master jaw 9 is moved near the workpiece, again with the special spanner worm screw 7 that turns clockwise, drive worm gear 6 by worm screw 7, worm gear 6 connects the transmission that screw mandrel 5 reaches power by connecting flat key 3, thereby realizes the mechanical booster chucking of workpiece; Otherwise, realize that then machinery unclamps; The end play of worm screw 7 guarantees by the axial adjusting pad 8 of reconditioning.This mechanical booster gripping mechanism can be realized fast moving and forward and reverse reinforcement chucking, and utilize the transmission of worm gear 6 worm screws 7 can realize self-locking owing to adopt the type of belt drive of worm screw 7 worm gears 6.Simultaneously, four mechanical booster gripping mechanisms are installed on chuck, can be tightened and unclamp workpiece convenient, fast, laborsaving, reliably; Reduced labor strength, shortened non-cutting time, improved the cost performance of labor productivity and lathe, controlled the increase of cost, thereby solved the brute force chucking of common feed screw nut's type of belt drive well and unclamp and the contradiction of the rapid increase of institute's cost that causes when adopting mechanical grip screw chucking.
