Description

It is diagonal to adjust version zero-bit accurate-location device

Technical field

The utility model relates to the printing plates in a kind of printing machine to angle adjusting mechanism, more particularly to a kind of diagonal tune version zero Position accurate-location device.

Background technique

Due to the picture and text chromatography requirement in multiple printing machines in normal printing process, the plate cylinder of each unit is equal Design has axial, radial printing plate adjustment mechanism, and with the raising of press quality, printing plate diagonally adjusts (also referred to as oblique pull version) technology Also more in application in the design of book and periodical printing machine.

The diagonal zero point for adjusting plate structure diagonally to adjust version functional module is by drawing on eccentric bushing and wallboard respectively at present Line, two lines are to just coming small change site.It is influenced by the range estimation ability of the scribing line gentle assembly crewman of dampening, the precision of zero-bit is not Height, to influence diagonal tune version zero-bit precision.

In the prior art, apply on books and periodicals machine printing machine to angle adjusting mechanism monnolithic case figure institute as shown in Figure 1, Figure 2 Show, the datum mark of books and periodicals machine is rubber cylinder, as long as plate cylinder is parallel with rubber cylinder.It is diagonal to adjust version module: when Printing image-text one side register, other end skew, is unable to register, diagonal oblique adjusting trace regulation is at this moment needed to operate plate cylinder Face has micro tilt angle with respect to driving face.Because being difficult to make 4 groups of printing plate position precision one during plate-making and curved version It causes.The diagonal mechanical zero for adjusting version is the plate cylinder guarantee parallel with rubber cylinder.

Mechanism principle: eccentric bushing is mounted in operation facing-wall board hole, driving face wallboard wall plate hole center and eccentric bushing it is interior Hole center is coaxial relation, in order to guarantee that roller and benchmark roller keeping parallelism, the periphery of eccentric bushing draw to obtain line and wallboard hole Line coincidence just can guarantee.

It is influenced by the range estimation ability of liner's level and assembly crewman, the precision of zero-bit is not high.

Utility model content

The purpose of the utility model is to provide a kind of diagonal tune version zero-bit accurate-location devices.

The purpose of this utility model is achieved through the following technical solutions:

The diagonal tune version zero-bit accurate-location device of the utility model, eccentric bushing are fixed on the wallboard of operating surface, and partially Heart set is mounted in the wallboard hole of operating surface, and mechanical positioner is equipped between the eccentric bushing and the wallboard hole.

The diagonal tune version provided by the embodiment of the utility model it can be seen from above-mentioned technical solution provided by the utility model Zero-bit accurate-location device improves the precision of the diagonal mechanical zero for adjusting version module and improves, and is overlapped using mechanical zero former Reason allows small change position and reset zero-bit to become simply to be easy, more reliable, improves the diagonal zero-bit precision for adjusting version module.

Detailed description of the invention

Fig. 1, Fig. 2 are respectively that the eccentric bushing of diagonal tune version zeroing fixture in the prior art and the structure in wallboard hole are shown It is intended to.

Fig. 3, Fig. 4 be respectively it is provided by the embodiment of the utility model it is diagonal adjust version zero-bit accurate-location device wallboard hole and The structural schematic diagram of eccentric bushing.

In figure:

1, eccentric bushing, 2, zero line on eccentric bushing, 3, wallboard, 4, zero line on wallboard hole；

5, pin hole, 6, pin grooves (locating slot).

Specific embodiment

The utility model embodiment will be described in further detail below.Do not make in the utility model embodiment in detail The content of description belongs to the prior art well known to professional and technical personnel in the field.

The diagonal tune version zero-bit accurate-location device of the utility model, preferable specific embodiment is:

Eccentric bushing is fixed on the wallboard of operating surface, and eccentric bushing is mounted in the wallboard hole of operating surface, the eccentric bushing Mechanical positioner is equipped between the wallboard hole.

The mechanical positioner includes the pin hole in the wallboard hole and the pin set on the eccentric bushing edge Slot installs pin between the pin hole and pin grooves.

The diagonal tune version zero-bit accurate-location device of the utility model, using mechanical zero be overlapped principle, allow small change position and Resetting zero-bit becomes simply to be easy, more reliable, improves the diagonal zero-bit precision for adjusting version module.It improves zero-bit positioning and answers Position precision is processed part by the high-precision of lathe and determined, reduces the requirement to operator's level.

Specific embodiment:

As shown in Figure 3, Figure 4.

Mechanism principle: pin hole site when finding zero-bit on wallboard hole according to the diagonal mechanism principle for adjusting version module passes through Numerically-controlled machine tool is processed, and the position precision of pinhole is guaranteed on wallboard；Eccentric bushing processes pin grooves, is positioning with pin grooves Point processing eccentric bushing inside and outside circle, though the processing anchor point of pin grooves eccentric bushing, and be zero-bit of the eccentric bushing on wallboard hole Point here using the installation of standard pin guarantees that quasi- timing and maintenance reset and uses.The structure makes full use of machine finish, Human error is eliminated, and improves diagonal drawing version reseting precision.

The utility model is not only applicable to the diagonal Tiao Ban mechanism design of book and periodical printing machine, simultaneously because the installation of mechanical zero It is simple and reliable with resetting, it applies also for original books and periodicals machine and increases diagonal tune version module；It is while meeting user's requirements at the higher level Enterprise provides more sale margin channels.

The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not It is confined to this, anyone skilled in the art can readily occur in the technical scope that the utility model discloses Change or replacement, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should Subject to the scope of protection of the claims.
