Abstract
The utility model relates to a central spindle planishing device, which comprises a support, and a roller central spindle arranged on the support through a support bearing, wherein a drive mechanism is fixedly connected onto the support; a nut capable of sliding up and down and pressing on a rear end part of the roller central spindle is arranged on the support; a screw rod matched with the nut is arranged in the nut; and the drive mechanism is connected onto the screw rod through a transmission mechanism and drives the screw rod to rotate. The central spindle planishing device overcomes the defects in the prior art and provides the planishing device for solving the problem that a central spindle is droopy.
Description
[technical field]
The utility model relates to a kind of printing element of set type flexible printing press, and what be specifically related to is the forme mandrel, net roller core shaft pressuring flat device.
[background technology]
The printing element of existing high-grade set type flexible printing machine, net roller, forme adopt telescoping structure more, because of sleeve will take out from fore side.So forme, the supporting construction of net roller core shaft mostly are a side fixed support of transmission, a side of operation is a movable supporting.After a side bearing of operation was opened, the mandrel front end all can be sagging, and sagging main cause is that mandrel is overweight, and is long, and mandrel produces distortion, and a side of transmission supports built on the sand, and flexible distortion causes, the size of sag of chain according to the weight of mandrel with length and different.Like this, when closing the bearing of operation one side again, sagging because of the mandrel front end causes bearing to close.
Existing way is: forme, the sagging very difficult solution of net roller core shaft, and sag of chain is little, how mandrel Leading end chamfer angle is increased, and increases the guiding length of bearing altogether the time, though can close bearing, effort is very big, and easily with the front end damage of bearings; If sag of chain is bigger, mostly be and use the lever people for levering up, very unreasonable.
[utility model content]
The utility model purpose is to provide a kind of sagging pressuring flat device of mandrel that solves in order to have overcome deficiency of the prior art.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposal:
A kind of net roller core shaft, forme mandrel pressuring flat device, it is characterized in that including bearing 1 and be located at roller core shaft 3 on the bearing by spring bearing 2, on bearing 1, be fixedly connected with driving mechanism 4, being provided with at bearing 1 can upper and lower slip and can be pressed in nut 5 on roller core shaft 3 rearward end, be provided with fit screw rod 6 with it in nut 5, driving mechanism 4 is connected on the screw mandrel 6 by transmission mechanism and drives screw mandrel and rotates.
Aforesaid a kind of net roller core shaft, forme mandrel pressuring flat device is characterized in that being provided with through hole 11 on described bearing 1, and described nut 5 places through hole and limits nut and rotate, and described screw mandrel 6 is arranged on the bearing 1 by screw mandrel bearing 7.
Aforesaid a kind of net roller core shaft, forme mandrel pressuring flat device is characterized in that described transmission mechanism includes the swing arm 8 that is fixedly connected on the screw mandrel 6, are articulated with rotating shaft 9 in swing arm 8, and the other end of this rotating shaft 9 is articulated on the described driving mechanism 4.
Aforesaid a kind of net roller core shaft pressuring flat device is characterized in that described driving mechanism 4 is the range-adjustable cylinder, and the cylinder rod that drives cylinder is fixedly connected on the rod end bearing 10, and rod end bearing 10 articulates with rotating shaft 9.
The utility model compared with prior art has following advantage:
The utility model is from causing the sagging main cause of mandrel, principle according to lever, with the spring bearing is fulcrum, adopt cylinder to drive screw mandrel, the roller core shaft rear end is depressed, force roller core shaft front end axle head to lift automatically, the mandrel front end can be overwhelmed horizontal state fully, thus when the supporting seat of front end closes again very easily and flexibly.

Fig. 1 is a schematic diagram of the present utility model.
Fig. 2 is the schematic diagram that cylinder connects swing arm.
Fig. 3 is the cooperation schematic diagram of screw mandrel and nut and roller core shaft.
[specific embodiment]
Below in conjunction with accompanying drawing the utility model is described in detail:
As shown in the figure, a kind of net roller core shaft pressuring flat device comprises bearing 1 and is located at roller core shaft 3 on the bearing by spring bearing 2, is fixedly connected with driving mechanism 4 on bearing 1.Being provided with at bearing 1 can upper and lower slip and can be pressed in nut 5 on roller core shaft 3 rearward end.In nut 5, be provided with fit screw rod 6 with it.Driving mechanism 4 is connected on the screw mandrel 6 by transmission mechanism and drives screw mandrel and rotates.
Specifically, be provided with through hole 11 on described bearing 1, described nut 5 places through hole and limits nut and rotate, and nut 5 can only upper and lowerly slide like this, and can not rotate.Described screw mandrel 6 is arranged on the bearing 1 by screw mandrel bearing 7.
Described transmission mechanism includes the swing arm 8 that is fixedly connected on the screw mandrel 6, is articulated with rotating shaft 9 in swing arm 8, and the other end of this rotating shaft 9 is articulated on the described driving mechanism 4.
Described driving mechanism 4 is for driving cylinder, and the cylinder rod that drives cylinder is fixedly connected on the rod end bearing on 10, and rod end bearing 10 articulates with rotating shaft 9.
Like this, when the front end of roller core shaft 3 will being moved down from bearing, then start the cylinder action earlier, cylinder rod then promotes swing arm 8 by rod end bearing 10 and rotates, thereby the rotation of swing arm 8 drives the rotation of screw mandrel 6, screw mandrel then promotes nut 5 to lower slider, and 5 on nut can suppress the end, rear end of roller core shaft 3.
