Abstract
The utility model discloses a large assembled chuck for solving the problem of unstable workpiece machining caused by large weight of the chuck and weight increase of the chuck of the existing machine tool of the class of enlarge rotary diameter. The utility model a base, a cutter frame, a base of a spindle box, the spindle box, a motor device connected with the spindle box, a chuck body connected with the spindle box through screws, and chuck jaws, wherein the chuck body is arranged on the spindle box, is connected with small chuck jaws through T-shaped screws, and is connected with the small chuck jaws also through a second lead screw; the small chuck jaws and the second lead screw can integrally move along a T-shaped groove on the chuck body; the base of the spindle box is provided with two auxiliary supporting devices through the screws; the exicrcle of the chuck body is support with an auxiliary supporting block which is connected with a third lead screw. Through the support of the auxiliary supporting devices and the variable disassembly of diameters of work pieces of large chuck jaws, the utility model can rotate stably when machining the workpieces, which can lighten the weight of the chuck and increase the bearing capacity of the machine tool.
Description
Technical field
The utility model relates to the chucks that is adapted to major diameter class part, a kind of specifically huge combined type chuck.
Background technology
In the lathe of big tactical diameter class, as numerical control end face face lathe, the diameter of work of machine tooling is Φ 3150mm, because tactical diameter is big, the vary in diameter scope of workpiece is big, when wanting clamping Φ 3150mm workpiece, the outside diameter of the main body of chuck will be Φ 3150mm at least, and lathe seems big especially relatively, makes chuck weight increase, the rotation instability of chuck when processing work, and weakened the bearing capacity of lathe.
The utility model content
The purpose of this utility model provides a kind of huge combined type chuck, and is big because of chuck body with the lathe that solves existing big tactical diameter class, and chuck weight increases, problem of unstable during processing work.
Chuck body, claw that the utility model comprises base, knife rest, main spindle box base, main spindle box, the electric machine that links to each other with main spindle box, links to each other with main spindle box by screw, described chuck body is contained on the main spindle box, chuck body links to each other with little claw by T shape screw, described chuck body links to each other with little claw by second screw mandrel, but the little claw and the second screw mandrel one move along the T type groove on the chuck body; By screw two secondary support means are housed on described main spindle box base, at the cylindrical upper support of chuck body the supplemental support piece are arranged, the supplemental support piece links to each other with the 3rd screw mandrel.
The utility model adopts assembly type eight dog chucks at the processing characteristic of large-scale dish, ring parts in design, big jaw body can be dismantled from chuck body.Chuck can be assembled along with the size variation of diameter of part.The dismounting that supporting by secondary support means and big claw diameter of work change, the spin stabilization of chuck when processing work has alleviated chuck weight like this, has improved the bearing capacity of lathe.Alleviated the deflection when workpiece clamps greatly.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is the outside drawing of lathe in the utility model;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the installation diagram of chuck in the utility model;
Fig. 4 is the A-A cutaway view among Fig. 3.
The specific embodiment
The Reference numeral implication is as follows: 1. base, 2. supplemental support, 3. knife rest, 4. chuck, 5. main spindle box, 6. electric machine, 7. main spindle box base, 8. chuck body, 9. screw, 10. big jaw body, 11. first screw mandrel, 12. claws, 13. second screw mandrels, 14. little claw, 15. supplemental support pieces, 16. the 3rd screw mandrels, 17. screw, 18. protective plates, 19.T shape screw.
Chuck body 8, claw that the utility model comprises base 1, knife rest 3, main spindle box base 7, main spindle box 5, the electric machine 6 that links to each other with main spindle box 5, links to each other with main spindle box 5 by screw, chuck body 8 is contained on the main spindle box 5, and chuck 4 can be assembled along with the size variation of diameter of part.Chuck body 8 links to each other with lesser calorie pawl 14 by T shape screw 19, rotate second screw mandrel 13, lesser calorie pawl 14 is moved along second screw mandrel 13, to realize clamping to the different-diameter workpiece, but lesser calorie pawl 14 and second screw mandrel, 13 one move along the T type groove on the chuck body 8 simultaneously, realize the clamping of diameter less than φ 1600mm workpiece.On described main spindle box base 7, two secondary support means 2 are housed by screw 17, cylindrical upper support at chuck body 8 has supplemental support piece 15, supplemental support piece 15 links to each other with the 3rd screw mandrel 16, secondary support means 2 can be come mobile back-up block 15 by rotating the 3rd screw mandrel 16, adjust the supporting of 2 pairs of chucks of secondary support means, make chuck spin stabilization, improved bearing capacity.Alleviated the deflection when workpiece clamps greatly.
When wanting the processing work diameter greater than φ 1600mm, by eight big jaw body 10 of screw 9 assemblings, realize the clamping of workpiece at chuck body 8 cylindrical places, big jaw body 10 links to each other with big claw 12 by first screw mandrel 11.Can rotate first screw mandrel 11 from the big jaw body 10 of chuck body 8 dismountings when unclamping screw 9, big claw 12 can move along first screw mandrel 11, to adjust the clamping range of 12 pairs of workpiece of big claw, makes the maximum grip scope of chuck reach φ 3150mm.Chuck body 8 is provided with protective plate 18.
The utility model is at the processing characteristic of large-scale dish, ring parts, and for improving the stable and working ability of lathe, big jaw body 10 is 8 in design.
The utility model mainly is applicable to the large diameter gyroaxis class of processing, dish cover class, and ring parts especially is adapted to the clamping of major diameter class part.
