Description
Technical field
This utility model relates to a kind of tail stock for machine tool, the particularly a kind of mode that holds out against tailstock for grinding slender axles workpiece more.
Background technology
Tail stock for machine tool is to cooperate with the headstock and workpiece rises a vitals of supporting, certralizing ability, position high, top, its center and all identical with the headstock with the structural shape of workbench faying face.Realizing holding out against of workpiece by the movement of tailstock, the realization of its moving movement is said good-bye and is moved and two kinds of patterns of surging.The tailstock of general middle-size and small-size cylindrical grinder, all supports workpiece by the thrust of spring, and spring force is too little, can make workpiece top loosely, not only affects grinding accuracy, even can produce accident；Spring force is too big, can make again small workpiece or slender axles deformation, and therefore when designing tailstock, how correctly design and the selection rational physical dimension of spring are critically important.Additionally, when user needs the slender axles of grinding plurality of specifications, due to the difference of slender axles size, required pressure is also not quite similar, now then needing different tailstock spring top clamp forces, in the case, general tailstock holds out against structure cannot be competent at.
Summary of the invention
In order to overcome the deficiencies in the prior art, this utility model provides a kind of tailstock holding out against mode more, it is possible to select hydraulic pressure to hold out against mode or spring mode carrys out top tight workpiece, and the pressure of spring can be adjusted.
This utility model solves its technical problem and be the technical scheme is that a kind of tailstock holding out against mode more, including body shell, sleeve, intensive ball, spring base, spring, slip cap, little axle, drive set, connecting rod, piston rod, spacer shell, supporting axle, set, described body shell top is built with sleeve and top, equipped with the intensive ball making the forward and backward movement of sleeve between body shell and sleeve；Described sleeve rear end is fixing connects spring base, and be slidably connected in spring base slip cap, and the connection axle placing spring, the aperture of slip cap rear end and little axle front end between spring base and slip cap is connected, and the screw mandrel at little axle rear portion is connected with driving set；Built with piston rod in the middle part of described body shell, piston rod rear end is equipped with spacer shell, equipped with supporting axle on the rear end face of described body shell bottom, sliding connection set on supporting axle, described drive set, spacer shell, set are fixed together by connecting rod, and the axis of little axle, piston rod, supporting axle is parallel with the axis of sleeve.
Described body shell is fixing on the table by two compact heaps.Described spacer shell is compressed on the piston rod by nut.Equipped with cushion block in described slip cap.
This utility model provides the benefit that, structure of the present utility model is initially with intensive ball tailstock structure, and therefore sleeve moves light, flexible, simultaneously because ball adopts interference fit, therefore mobile accuracy is high, and guidance quality is good.Secondly in tailstock body shell, design the structural shape of hydraulic cylinder, piston rod is driven to move by hydraulic system, piston rod and tailstock are fixed together to realize the purpose that hydraulic system drive sleeve moves by connecting rod, the more manual tailstock automaticity of the tailstock that surges is high, it is simple to be used on the lathe of high automatization.Meanwhile, spring base, slip cap, spring are increased in the rear end of tailstock, the parts such as little axle, realize the spring top clamping purpose of workpiece, and the adjustment to spring top clamp force can be realized by rotating little axle, realize meeting the demand of the different tailstock spring top clamp force of user's request.In addition, guide post mechanism is increased so that the motion of piston rod drive tailstock is more reliable and more stable.
Accompanying drawing explanation
Fig. 1 is the structure sectional view of the tailstock holding out against mode of the present utility model more.
Detailed description of the invention
Below in conjunction with drawings and Examples to this utility model further instruction.
As it is shown in figure 1, a kind of tailstock holding out against mode, including body shell 1, sleeve 2, intensive ball 3, spring base 4, spring 5, slip cap 6, cushion block 7, little axle 8, drive set 9, connecting rod 10, piston rod 11, spacer shell 12, supporting axle 13, set 14 more.
Body shell 1 is fixing on the table by two compact heaps.Top being arranged in sleeve 2, intensive ball 3 is between body shell 1 and sleeve 2 so that sleeve 2 can move left and right, it is achieved holding out against of workpiece.The movement of sleeve 2 is light, flexible, precision is high, guidance quality is good.Spring base 4 is fixed by screws in sleeve 2 right-hand member, moves with sleeve 2 simultaneously.Spring 5 is placed in spring base 4, is pressed in spring base 4 by spring 5 by slip cap 6.Little axle 8 front end is inserted in the aperture of slip cap 6, and the rear end of little axle 8 is made up of screw mandrel, and screw mandrel can realize relative movement with driving set 9.Cushion block 7 is arranged in slip cap 6.Rotate the reduction length of the amount of movement between little axle 8 adjustable sliding set 6 and spring base 4 and adjustable springs 5, different spring top clamp forces can be obtained.Drive set 9, spacer shell 12 and set 14 are fixed together by connecting rod 10.Spacer shell 12 is pressed on piston rod 11 by nut, piston rod 11 drive the movement of spacer shell 12.Supporting axle 13 is fixed on body shell, and the axis of supporting axle 13 is parallel with the ideal axis of sleeve 2, when overlapping 14 and moving left and right on supporting axle 13, the movement of sleeve is played guiding and the effect of location.
The use of intensive roll structure of the present utility model so that sleeve moves light, flexible, simultaneously because ball adopts interference fit, therefore mobile accuracy is high, and guidance quality is good.When needing the mode of hydraulic top clamping of workpieces, rotate clockwise little axle, owing to now piston rod does not move, therefore connecting rod transfixion, make drive set not move, then little axle and drive the screw thread between set to make little axially to move left.Piston rod move make top withstand workpiece after, slip cap and spring base compress, and spring is ineffective, and the pressure of workpiece is provided by tailstock center by hydraulic system；When needing the mode of spring top clamping workpiece, rotate counterclockwise little axle, make little axially to move right.Piston rod move make top withstand workpiece after, have amount of movement between slip cap and spring base, now spring is effective, and regulates the reduction length of the amount of movement between slip cap and spring base and adjustable springs, can obtain different spring top clamp forces.Supporting axle is fixed on body shell, and the axis of supporting axle is parallel with the ideal axis of sleeve, when be enclosed within supporting axle moves left and right time, the movement of sleeve is played guiding and the effect positioned.
