Abstract

The utility model relates to an improved structure of a transmission swing arm for a printing machine. The improved structure is characterized in that the transmission swing arm adopts a split structure and comprises a left side connecting part, a connecting vertical plate and a right side connecting part, wherein the left side connecting part, the connecting vertical plate and the right side connecting part are independent from one another, the two connecting parts are connected with the connecting vertical plate through a middle plate, and every two adjacent components out of the left side connecting part, the middle plate, the connecting vertical plate and the right side connecting part are respectively welded together. The structure has the advantages that the traditional casting transmission swing arm adopts the split structure, thus the processing difficulty is reduced, the accuracy is easy to guarantee, the assembly and welding are convenient, the structure is rapidly welded, and the intensity after welding is greater than that of a casting structure.

Description

A kind of printing press architecture advances of transmission swing arm

Technical field

The utility model belongs to the printer technology field, particularly relates to the architecture advances that a kind of printing press is used the transmission swing arm.

Background technique

Cast structure is generally adopted in existing printing press transmission swing arm; the transmission arm of this kind structure is when reality is used; might be because the birth defects that cause during fabrication; for example pore or sand holes etc.; crack or fracture often appear, thus the potential safety hazard of causing, in case find to have the problems referred to above just to need to shut down maintenance and change; will cause the shutdown of long period like this, thereby influence manufacturing efficiency.

Summary of the invention

The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, easy to install, intensity is high, the printing press of increasing work efficiency is with the architecture advances of transmission swing arm.

The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:

A kind of printing press architecture advances of transmission swing arm, it is characterized in that, described transmission swing arm is adopted and is divided body structure, include separate left side joint, connection board and right side joint, be connected with connection board by intermediate plate between described two joints, weld together respectively between described left side joint, intermediate plate, connection board and right side joint adjacent.

The utility model can also adopt following technological scheme:

Be welded with between described intermediate plate and the connection board and tiltedly draw stiffening rib.

Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, be about to traditional founding type transmission swing arm and adopt split-type structural, so at first its difficulty of processing descends to some extent, and precision is guaranteed easily, comparatively convenient when the assembling welding, can rapid welding survive, welding survives its intensity of back and is far longer than cast structure, in addition, the stiffening rib that tiltedly draws that increases further improves the intensity of its antifatigue, torque resistant, thereby prolonged its working life, reduced maintenance cost.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the plan view of Fig. 1.

Among the figure: 1, left side joint; 2, connection board; 3, right side joint; 4, intermediate plate; 5, stiffening rib.

Embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1 and Fig. 2, a kind of printing press architecture advances of transmission swing arm, described transmission swing arm is adopted and is divided body structure, include separate left side joint 1, connection board 2 and right side joint 3, be connected with connection board 2 by intermediate plate 4 between described two joints, weld together respectively between described left side joint 1, intermediate plate 4, connection board 2 and right side joint 3 adjacent.

Said structure adopts split-type structural with traditional founding type transmission swing arm, so at first its difficulty of processing descends to some extent, and precision is guaranteed easily, and is comparatively convenient when the assembling welding, can rapid welding survive, welding survives its intensity of back and is far longer than cast structure.

In addition, the stiffening rib that tiltedly draws of increase further improves the intensity of its antifatigue, torque resistant, is welded with between described intermediate plate and connection board and tiltedly draws stiffening rib 5, thereby prolonged its working life, has reduced maintenance cost.

Although by reference to the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection domain of the present utility model.

Claims

1. a printing press is with the architecture advances of transmission swing arm, it is characterized in that, described transmission swing arm is adopted and is divided body structure, include separate left side joint, connection board and right side joint, be connected with connection board by intermediate plate between described two joints, weld together respectively between described left side joint, intermediate plate, connection board and right side joint adjacent.

2. printing press according to claim 1 is characterized in that: be welded with between described intermediate plate and the connection board and tiltedly draw stiffening rib with the architecture advances of transmission swing arm.
