Abstract
The utility model discloses a bearing-ring turning numerical-control lathe which is a turning fixture suitable for machining a bearing-ring specially. The bearing-ring turning numerical-control lathe comprises a dragging plate for a bearing worktable; the dragging plate is arranged on a guiding rail which is firmly connected with the inner lateral surface of a hydraulic cylinder retaining plate vertically; a hydraulic cylinder is fixedly connected to the outer lateral surface of the retaining plate; one end of a piston rod passes through the retaining plate and connected with one end of a double-threaded screw; and the other end of the double-threaded screw is connected with the dragging plate. The bearing-ring turning numerical-control lathe adopts the double-threaded screw and the piston rod to connect the worktable with the hydraulic cylinder, so as to replace the original rigid connection manner of utilizing the piston rod directly, the position of the worktable can be adjusted freely, the stable running of the worktable can be ensured, and the phenomena of oil leakage of the hydraulic cylinder and the pressure due to damages to the a sealing element of the hydraulic cylinder caused by the deflection of the piston rod can be prevented.
Description
Technical field
The utility model discloses a kind of bearing ring turning digital control lathe, is the truning fixture that is specially adapted for bearing ring processing.
Background technology
Conventional bearing ring turning digital control lathe, its workbench directly is connected with general employing of hydraulic cylinder, be that the piston rod end in planker side end face and the hydraulic cylinder is connected on the workbench baseplane, this direct-connected mode also is called hard connection usually, because when processing its end face, can't guarantee absolute vertical its guide pass at workbench planker and guide rail, thereby just can't guarantee that workbench is consistent with the vertical line and the horizontal line of hydraulic cylinder, so tend to make the flexible flexibility ratio of piston rod not enough, fault such as cause the workbench speed of service to slow down even stuck, and damage the sealing ring of piston rod easily at the hydraulic cylinder external part, can cause the hydraulic cylinder leakage of oil when seal is damaged then, and pressure fault such as reduces and occurs.
The utility model content
The utility model is at the deficiencies in the prior art, and purpose is to provide a kind of bearing ring turning digital control lathe, by adding double-threaded screw is installed, change the workbench connected mode, the assurance workbench is stable, prolong hydraulic cylinder sealing element service life, and it is less to increase cost.
The technical solution adopted in the utility model is: a kind of bearing ring turning digital control lathe, it is characterized in that: comprise the planker that carries workbench, planker places on the guide rail, vertical being connected of medial surface of guide rail and hydraulic cylinder fixed head, the outside of fixed head is fixed with hydraulic cylinder, piston rod passes fixed head and is connected with an end of double-threaded screw, and the other end of double-threaded screw connects planker.
The utility model further is set to:
The baseplane of described workbench is provided with the swallow-tail form projection, and the upper surface of planker is provided with and swallow-tail form projection immovable fitting dovetail groove.Workbench and planker are for closely cooperating, be after the swallow-tail form projection is pushed the other end of dovetail groove by an end, workbench baseplane and plane, planker upper surface also fit tightly, and swallow-tail form projection and dovetail groove are interference fits, and swallow-tail form projection and workbench are integral structure.
The upper surface of described guide rail is provided with the rail groove along the longer sides direction, and the planker cooperation places on the guide rail, and does reciprocating linear motion with the rail groove.
The two ends of described double-threaded screw are provided with the screw thread that matches with left and right nut, and double-threaded screw links to each other with planker, piston rod respectively by left and right nut.Having additional of this double-threaded screw is beneficial to the twisted phenomena that reduces piston rod, improves the stationarity of movable workbench, prolongs the service life of hydraulic cylinder.The effect of left and right nut is the connection between fastening double threaded screw and the planker, and the distance of regulating planker and hydraulic cylinder.
Described piston rod 4 is by hauling out in the piston cylinder in the hydraulic cylinder 6, and the connecting portion of piston cylinder and fixed head 5 is provided with round nut 7.
The utility model will adopt double-threaded screw to link to each other with piston rod between workbench and the hydraulic cylinder, replace the original rigid ways of connecting of piston rod of directly passing through.Originally directly there was piston rod to connect, often be difficult to guarantee that workbench and hydraulic cylinder piston rod keep level with vertical, injury to piston cylinder is bigger in process of production, make piston rod damage the seal of cylinder ends cap position easily, damage the fault that seal also will cause hydraulic cylinder leakage of oil and motion stress to reduce.Now, after piston rod connected double-threaded screw, the planker that connects the workbench bottom again by double-threaded screw, so not only guaranteed the stable of workbench, reduced the injury to piston cylinder, prevented that adjusting the improper piston rod that makes because of workbench is subjected to big distortion power to damage hydraulic cylinder sealing element, most of distortion power is absorbed by double-threaded screw, adjust the position of workbench according to the debugging situation, thereby prolong the service life of parts such as piston rod and hydraulic cylinder sealing.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
