Detailed Description
The invention will be further explained with reference to the drawings.
Referring to fig. 1 to 3, the axial adjusting mechanism of the printing press according to the present invention is used for the axial registration of a plate cylinder 1, and a driving side shaft head of the plate cylinder 1 is connected to a cylinder driving motor 10 through a set of transmission mechanism; the transmission mechanism comprises a driving gear 11 connected to a rotating shaft of the cylinder driving motor 10 and a transmission gear 12 meshed with the driving gear 11 and sleeved on a shaft head of a driving side of the plate cylinder 1, wherein the driving gear 11 and the transmission gear 12 are both arranged in a gear box 13, and the gear box 13 is arranged on the outer side surface of a driving side wall plate of the printing machine; the drive side stub shaft of the plate cylinder 1 is also fitted with a bearing 14 at the rear end of the drive gear 12, the bearing 14 being fitted within a bearing housing 15.
The axial adjusting mechanism of the printing machine comprises an axial adjusting motor 20, a guide mandrel 22, an external thread sleeve 23, an internal thread sleeve 24 and a limiting seat 25; wherein,
the axial adjustment motor 20 is mounted on the outer side of the gear box 13 coaxially with the plate cylinder 1 by means of a support 26;
the rear end of the guiding mandrel 22 is connected with the rotating shaft of the axial adjusting motor 20 through a coupling 21;
an external thread sleeve 23 is sleeved on the guide mandrel 22 through a key, and a front end flange of the external thread sleeve 23 is connected with a bearing seat 15 on a driving side shaft head of the plate cylinder 1;
the internal thread sleeve 24 is connected to the external thread sleeve 23 in a threaded manner, and the front end flange of the internal thread sleeve 24 is fixed on the outer side face of the gear box 13;
the limiting seat 25 is slid on the guide mandrel 22 and connected to the rear end of the internal thread sleeve 24.
The working principle of the axial adjusting mechanism of the printing machine is as follows: the axial adjusting motor 20 is provided with a guide mandrel 22 to rotate, because the external thread sleeve 23 is sleeved on the guide mandrel 22 through a key, the external thread sleeve 23 can not do circumferential motion relative to the guide mandrel 22 and can only do axial motion, therefore, the external thread sleeve 23 also synchronously rotates along with the guide mandrel 22, the internal thread sleeve 24 is in threaded connection with the external thread sleeve 23, and the internal thread sleeve 24 is fixed on the gear box 13 and can not rotate, therefore, the external thread sleeve 23 can do axial motion along the guide mandrel 22 while rotating, the axial motion of the external thread sleeve 23 drives the bearing seat 15 and the bearing 14 in the bearing seat 15 to do axial motion together, the motion of the bearing 14 drives the plate cylinder 1 to move, and the purpose of axial registration of the plate cylinder 1 is realized. During the movement of the external thread bushing 23, the guiding mandrel 22 ensures that the direction of movement of the external thread bushing 23 does not deviate. The limiting seat 25 connected with the rear end of the internal thread sleeve 24 plays a role in limiting the movement of the external thread sleeve 23, and ensures that the movement of the plate cylinder 1 cannot exceed the range.
The above embodiments are provided only for illustrating the present invention and not for limiting the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and therefore all equivalent technical solutions should also fall within the scope of the present invention, and should be defined by the claims.
