Description

A kind of CNC heavy-duty horizontal lathe tailstock chuck
Technical field
The utility model belongs to field of machining, is related to CNC heavy-duty horizontal lathe more particularly to a kind of NC heavy Horizontal lathe tailstock chuck.
Background technology
Currently, domestic existing CNC heavy-duty horizontal lathe, when meeting thin-wall part, elongate articles processing, in order to ensure work Part both ends centering, prevents workpiece from trembling, and meets the machining accuracy of workpiece and the safety of operation.It is required that CNC heavy-duty horizontal lathe Band tailstock chuck assembly, all CNC heavy-duty horizontal lathes can only cannot be satisfied adding for heavy parts with light-duty tailstock chuck Work.In mandrel, mandrel is inserted in tailstock centre taper hole common chuck assembly, then puts together on tailstock set with the flange of mandrel On cylinder, sleeve stretches out together when stretching out, and load-bearing capacity is very low, inconvenient to use, can not use top, loses protocercal tail seat Tightly-pressing function cannot meet 63 tons or more of CNC heavy-duty horizontal lathe tailstock weight-bearing function.
Utility model content
For existing CNC heavy-duty horizontal lathe there are the problem of, the utility model, which provides, a kind of meeting 63 tons or more The Tailstock of Heavy Horizontal Lathe chuck assembly of CNC heavy-duty horizontal lathe tailstock load-bearing requirements.
To achieve the goals above, this utility model uses following technical scheme:A kind of CNC heavy-duty horizontal lathe tail Seat chuck, including tailstock, are set with sleeve in the tailstock upper body of the tailstock, and socket end end is fixedly arranged in the middle of top, tailstock Upper body end end is fixed with tailstock chuck body, and tailstock chuck body is equipped with claw, and master jaw is installed by bolt pair on chuck body, Claw is installed in by reinforcement lead screw on master jaw.
The tailstock chuck body and the ring flange of its rear end are connected by screw and are fixed on bearing, before bearing and chuck body The ring flange at end, which is connected by screw, to be fixed on tailstock upper body, is used for adjusting bearing clearance by spacer between two bearings, be ensured The service precision of bearing.
The beneficial effects of the utility model are:The utility model expands the function of CNC heavy-duty horizontal lathe Exhibition.Tailstock chuck body is fixed on tailstock upper body by bearing and ring flange, then master jaw is mounted in chuck body with bolt pair On, refill upper clipping claw.Tailstock chuck uses reinforcement lead screw as spindle box chuck function, and the clamping force of super large, single action is adjustable, It also ensure that the CNC heavy-duty horizontal lathe tailstock tightly-pressing function of 63 tons of workpiece weight or more simultaneously, gripper chuck is next to have self-locking Performance ensures to be reliably clamped after power source cut-out, and reinforcement leading screw clamping force is big, operational torque is small, and cooperation torque spanner can Realization quantitatively adjusts clamping force;Or by special tooling electronic rotation reinforcement lead screw, claw movement folder is driven by screw-driven Clamping of workpieces, since the lead angle of reinforcement lead screw trapezoidal thread is far smaller than the equivalent friction angle of bolt pair, to ensure safety;Folder Tight rigidity is high, it is precisely firm, easy to operate, versatile to clamp;It is simple and reasonable, have sufficiently large static dynamic rate etc. Feature.CNC heavy-duty horizontal lathe can be made to have and ensure workpiece both ends centering, prevent workpiece from trembling, meet the machining accuracy of workpiece With the security functions of operation.
Description of the drawings
A kind of structural schematic diagrams of CNC heavy-duty horizontal lathe tailstock chuck assembly of Fig. 1;
The left view of Fig. 2 Fig. 1.
In figure:1, chuck body;2, the first and second bearing;3, spacer;4, second flange disk;5, screw;6, sealing ring;7, tail Seat upper body;8, sleeve;9, first flange disk;10, bolt pair;11, master jaw;12, claw;13, reinforcement lead screw.
Specific implementation mode
The utility model is described further below in conjunction with attached drawing, example is served only for explaining the utility model, and It is non-to be used to limit the scope of the utility model.
A kind of CNC heavy-duty horizontal lathe tailstock chuck, including tailstock are set with sleeve in the tailstock upper body 7 of the tailstock 8, being fixedly arranged in the middle of for socket end end is top, and 7 end end of tailstock upper body is fixed with tailstock chuck body 1, round tailstock chuck body 1 Master jaw 11 is installed by bolt pair 10 on upper and lower, left and right, passes through one claw of installation of reinforcement lead screw 13 on each master jaw 11 12。
7 front end of tailstock upper body is equipped with the first and second bearing 2, is used for adjusting bearing clearance by spacer 3 between two bearings, protect Demonstrate,prove the service precision of bearing;Tailstock chuck body 1 and the second flange disk 4 of its rear end are mounted on two after being connected and fixed by screw 5 On bearing;First bearing is mounted in the front end of tailstock upper body 7, is connected by screw with the first flange disk 9 of 1 front end of tailstock chuck body It is fixed.Entire tailstock chuck body 1 can be made to be rotated on tailstock upper body 7 by two bearings, realize the workpieces processing on lathe It is required that.
The tailstock chuck device has the clamping force of super large, and single action is adjustable, also to ensure the numerical control weight of 63 tons or more workpiece Type horizontal lathe tailstock tightly-pressing function has self-locking property after clamping, ensure to be reliably clamped after power source cut-out, to ensure Safety;And it is simple in structure easy to operate.
In use, first unclamp bolt pair 10 moves near workpieces by master jaw, bolt pair 10 is tightened, master jaw 11 is fixed On chuck body 1, claw 12 is mounted on by reinforcement lead screw 13 on master jaw 11, is then rotated reinforcement lead screw 13, is made claw 12 It moves inward, clamps workpiece.Chuck body 1 is to meet the use purpose that the tailstock of CNC heavy-duty horizontal lathe clamps workpiece.Due to Sleeve 8 is sleeved in the form of existing be slidably matched on tailstock upper body 7, can by drive sleeve when workpiece needs to hold out against So that sleeve 8 is directly stretched, with top top tight workpiece among sleeve, the tailstock work(of original CNC heavy-duty horizontal lathe is kept Can, it reaches the tailstock clamping of CNC heavy-duty horizontal lathe and holds out against the requirement being all suitable for.
