A press plate is fixed on a machine frame; a hole on the middle part of the press plate is provided with a support shaft; the right end of the support shaft is provided with a screw thread; a locknut is arranged on the support shaft; the left end of the support shaft is provided with a boss; a bearing and a support sleeve are orderly arranged on the support shaft near to the boss; the right end of the support sleeve is contacted with the press plate; the left end of an outer ring of the bearing is tightly adjoined with a step hole on the middle part of the cylinder; the right end of the outer ring of the bearing is contacted with a regulation pad in a press cover; the press cover is fixed on the shaft end of the cylinder; the inner side and the outer side of the press cover are provided with a regulation pad; double rows of cylindrical roller bearings are arranged between the cylinder and the round hole of the machine frame; the inner ring of the cylinder is contacted with the outer regulation pad of the press cover. The utility model has the advantages of accurate and reliable axial positioning of a printing press cylinder.
Description
The utility model belongs to the axial direction positioning device of the axial direction positioning device of lathe rotating shaft, particularly cylinders of printing press.
Printing machine cylinder at work carries out high speed rotation, and any axial float of cylinder can influence the precision of printing machine, causes the generation of spoilage.Axial direction positioning device such as Fig. 1 of existing cylinders of printing press, one end of cylinders of printing press is bearing on the lining of frame by two relative taper roll bearings, its outer shroud is made axial restraint by adjustment nut, spacer ring, gland, tighten clamp nut, ring move toward one another under the effect of clamp nut and cylinder step in two, the working clearance of two taper roll bearings of adjustment.This moment, taper roll bearing promptly play supporting role, and also played the axial location effect.Gap between taper roller and the inner and outer rings includes end play, and it can cause the axial float of cylinders of printing press.Therefore, in order to improve the printing precision of printing machine, must eliminate the axial float of existing cylinders of printing press.
The purpose of this utility model is that a kind of cylinders of printing press axial direction positioning device that can guarantee cylinders of printing press axial location precision will be provided.
The axial direction positioning device of cylinders of printing press, the purpose of this utility model is achieved in that pressing plate is fixed on the frame, the pressing plate center has circular hole, fulcrum is housed in the hole, the fulcrum right-hand member has screw thread, be screwed with locknut on it, between pressing plate and locknut, lock washer is housed, the left end of fulcrum has a convex, by convex at least two roller bearings and splicing sleeve are housed successively on fulcrum, the other end of splicing sleeve contacts with pressing plate, and the left end of outer race is near the stepped hole of centre of the drum, right-hand member contacts with adjusting pad in the gland, gland is fixed in the axle head of cylinder, and adjusting pad is equipped with in the inside and outside both sides of gland, and a Biserial cylindrical roller bearing fixedly is housed between the circular hole of cylinder and frame, right-hand member of ring contacts with the outer adjusting pad of gland in it, can be in axial sliding between interior ring and the cylindrical roller.
The adjusting pad of the inside and outside both sides of gland, be to treat to match after other correlated parts assembling is finished to install, or according to the right-hand member that encircles in the accurate measurement Biserial cylindrical roller bearing and gland left end, the right-hand member of two roller bearing outer shrouds and the gap size of gland left end, the adjusting pad of special processing.
The center of fulcrum has circular hole, and the left end of the stepped hole of centre of the drum also is equipped with successively, and the center has the axle of screwed hole stifled, and the stifled right-hand member of axle contacts with the left end of roller bearing outer shroud.
Advantage of the present utility model: to be fixed in the end of the isolated plant fixing printing machine cylinder on the fuselage, its axial location accurately, reliably; Simultaneously, cylinders of printing press is supported on the fuselage by Biserial cylindrical roller bearing, has strengthened support stiffness, has reduced the circular runout of cylinders of printing press end.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Fig. 1 is the axial direction positioning device of former cylinders of printing press
Fig. 2 is the axial direction positioning device of this cylinders of printing press
At least four screws 4 pass the uniform circular hole in pressing plate 13 edges, be screwed in the screwed hole of frame 2, the pressing plate center has circular hole, fulcrum 9 is housed in the hole, the fulcrum right-hand member has screw thread, be screwed with locknut 8 on it, lock washer 10 is housed between pressing plate and locknut, the left end of fulcrum has a convex, by convex at least two roller bearings 16 and splicing sleeve 11 are housed successively on fulcrum, the other end of splicing sleeve contacts with pressing plate, and the left end of two roller bearing outer shrouds is near the stepped hole of centre of the drum, and right-hand member contacts with adjusting pad 7 in the gland 6, at least four screws 12 pass circular hole uniform on the gland, be screwed in the screwed hole of cylinder 18 ends, adjusting pad is equipped with in the inside and outside both sides of gland, and a Biserial cylindrical roller bearing 1 is housed between the circular hole of cylinder and frame, the right-hand member of ring contacts with the outer adjusting pad 5 of gland in the Biserial cylindrical roller bearing, and with cylinder between contact with the corresponding conical surface, at the two ends of outer race back-up ring 14 is housed respectively, 3, can be in axial sliding between bearing inner ring and the cylindrical roller.
In order to guarantee the axial location precision of cylinders of printing press, the adjusting pad 7,5 of gland 6 inside and outside both sides, be to treat to match after other correlated parts assembling is finished to install, or according to the right-hand member and gland left end, the right-hand member of two roller bearing 16 outer shrouds and the gap size of gland left end that encircle in the accurate measurement Biserial cylindrical roller bearing 1, the adjusting pad of special processing.
The center of fulcrum has circular hole, and the left end of the stepped hole of centre of the drum also is equipped with successively, and there is the axle stifled 17 and the spacer ring 15 of screwed hole at the center, and the right-hand member of spacer ring contacts with the left end of roller bearing outer shroud.
