Description
Technical field
The utility model relates to the auxiliary equipment in a kind of machined working angles, specifically is meant a kind of centre frame of machined stock-removing machine.
Background technology
In machining industry, particularly in the cut of slender piece, usually use centre frame.Centre frame is the servicing unit of work in-process radial support rotational workpieces; In processing thin and long shafts part, draw ratio L/D>15, produce flexural deformation in order to prevent workpiece to receive the effect of radial cutting force; The common central frame is as aiding support, to increase the workpiece rigidity.Add man-hour, do not have with workpiece and move to axial, centre frame should be fixed on the lathe bed, and with the thick centering of scriber, behind the lubricating oil, machine tool low speed changes according to the thickness and the weight of material turns speed, according to the feel centering on the point.Centre frame is mainly used in the turning of large-diameter workpiece axial end, behind workpiece selection centre frame position, centre frame is fixed on the bed ways, rotates the adjustment center at a slow speed, and is suitably grease-added between centre frame pawl post and workpiece.What centre frame was just not serious can only reinstall or change, and the light length that can adjust 3 contact studs is all unclamped three posts earlier and let main axis rotation; Adjust the centre frame contact stud then to workpiece, the strength of three posts should be identical, sees whether the rotation of workpiece beats after touching workpiece; Slowly find the optimum position according to beating of workpiece; Processing then because trickle adjustment is also wanted in the wearing and tearing of contact cylinder, will add enough lubricating oil during finish turning and cooling fluid reduces wear in the process.Centre frame mainly is used for processing long workpiece, is installed between chuck and the knife rest; Follow-rest is used and the processing slim axle, is installed on the slip crate, moves with knife rest, to increase the turning rigidity.Each cylindrical of processing slim multidiameter generally is bearing in centre frame the middle part of axle, first each cylindrical of car right-hand member, the cylindrical of the car other end again behind the same clamping in tune back; The end face of processing major axis or long tube (like cylinder body), and the hole of end and screw thread etc., available chuck clamping workpiece left end leans on medium position slightly with centre frame supporting right-hand member or right-hand member.In the adjustment support column,, be easy to generate locking phenomenon in the turning process if strength is excessive; If strength is too small, product forms ellipse easily.
The utility model content
The purpose of the utility model is to overcome present centre frame when the clamping workpiece, stressed difficult adjustment, causes the loosening problem that forms the oval or stressed excessive formation locking of workpiece end face of workpiece easily, and a kind of centre frame of machined stock-removing machine is provided.
The purpose of the utility model realizes through following technical proposals:
A kind of centre frame of machined stock-removing machine; Comprise mount pad; Mount pad is provided with the centre frame body; The centre frame body is provided with three adjusting tubes that are used to control distance between top wheel and the centre frame body axle center, regulates tube and runs through the centre frame body, is positioned at the intrinsic end of centre frame at three adjusting tubes the top wheel all is installed.The mount pad of centre frame body is installed on the guide rail of lathe; The top wheel is installed on the adjusting tube of centre frame body; Through adopting the mode of pushing up wheel, convert the frictional force between workpiece and the top wheel into the force of rolling friction that takes turns on the top, effectively overcome the locking problem between workpiece and the centre frame.
Said top wheel comprises the top tube; The top tube is whole cylindrical, and an end face of tube is connected with Coupling on the top, and another end face of tube is provided with mounting groove on the top; Two sides of mounting groove on the tube of top are parallel to each other and are symmetrical about the axis of top tube; Bearing is installed in mounting groove, and the two ends of bearing are connected on two sides of top tube mounting groove, on bearing, are set with roller; The radius of roller is greater than the axis of the bearing distance to the top tube end face at mounting groove place, and said top wheel tin is connected with regulating through Coupling.On the tube of top, cut out a mounting groove, the opening of this mounting groove is in the end face and the cylinder sides of top tube, and mounting groove is positioned at the middle part of end face at the opening of end face; Two sides in the tube of top of mounting groove are parallel to each other, and symmetrical about the axis of top tube, and bearing is installed in mounting groove; Bearing is connected on the top tube of mounting groove both sides, and its axis is parallel with the end face of top tube, on bearing, is set with roller; The radius of roller is greater than the distance between the upper surface of the axis of bearing and top tube, so, and after the Coupling center of being socketed in of top tube added; Active force between top tube and the workpiece is decomposed into both direction, along the tangential direction of workpiece with along the diametric(al) of workpiece, makes roller rotate around bearing along the power of the tangential direction of workpiece; Reduce the frictional force between top tube and the workpiece, avoided workpiece to be pushed up the situation of a locking.
Described Coupling is provided with the gathering sill that is parallel to top tube axis, in regulating tube, is provided with the gib block that is complementary with gathering sill.In order to keep pushing up the position of wheel, make the top wheel when regulating its can be around the top axis of tube rotate, Coupling is provided with gathering sill, through on the adjustable column of centre frame, gib block being set, matches with gathering sill, the situation of having avoided the top wheel to rotate.
Said adjusting tube is provided with rotating disk, and rotating disk is connected with the top wheel through the screw rod of regulating in the tube.In order to adapt to the needs of different workpieces, drive the screw rod of regulating in the tube through rotating disk, screw rod promotes the top wheel and moves along the diametric(al) of centre frame body, regulates the position of workpiece on the centre frame with this.
The utility model compared with prior art has following advantage and beneficial effect:
The centre frame of a kind of machined stock-removing machine of 1 the utility model; The top wheel is installed on the adjusting tube of centre frame body, converts the frictional force between workpiece and the centre frame body to force of rolling friction, reduced workpiece by the situation of locking; Simultaneously; Through the drive of rotating disk, can regulate the active force between top wheel and the workpiece, make workpiece stressed evenly;
The centre frame of a kind of machined stock-removing machine of 2 the utility model; Through on the tube of top, mounting groove being set; Bearing is installed in mounting groove, and the mode of suit roller on the bearing converts the frictional force between top wheel and the workpiece to force of rolling friction; Reduce workpiece by the situation of locking, helped the processing of workpiece.
